# Argus extraction contract v1 — specification (revision 9 — the build-slice amendment of 2026-09-07; revision 8 ACCEPTED 2026-09-06 by both independent reviewers at round 8, head 601edf8)

> *Naming (see `naming-glossary.md`): Argus is the module built from the FDR skill; Sibyla is the platform; the Invoice Skill Build (`D:\fileStorage\repos\invoice-skill-build`) is the FDR's own repository and skill. "v1" in this document's title is the owner's milestone name of 2026-09-05 ("contract v1 = the section 5 field list"). The wire identifier is **not** `…v1` — `sibyla.extract.v1` was cut on 2026-09-02 and is already in evidence rows (Q-EX-1).*

*Revision 9, 2026-09-07 (build slice, branch `ops/argus-extraction-v1-red`): the amendment the closing verdict of round 8 carried into the build slice — the eight residual findings C-X-1, C-X-2, C-X-3, C-X-4 = F-X-1, F-X-2, F-X-3 and F-X-4, applied exactly as that verdict states them and dispositioned in the review record ("Author's dispositions — revision 9 (build slice)"). Nothing else in the accepted revision 8 is touched, and no further spec change is made in this slice without a new review round. No new owner question; D-EX-4 stands.*

**What changed from revision 8, by section.** §2.8: V-8's second-shape label reads "the duty-inside shape: branch (2), or branch (3) with a zero difference" (C-X-2); V-9's VAT clause also accepts `Σ lines.vat + |duty| = header.vat ± 0.02` when `duty` is non-null and no `stamp_tax` line is printed — the branch-(2) shape (C-X-1). §4.3: the R-EX-2 `--verbose` flag lives in `const bool StreamJsonNeedsVerbose` on `ClaudeCliProcess`, `false` at RED (C-X-4 = F-X-1; **it is `true` since R-EX-2 of 2026-09-07 proved the pinned CLI refuses stream-json without it** - this line records what revision 9 changed, not the value today); the sibling-release enumeration root is the parent of the release directory, `C:\Apps\Sibyla\worker` in production (F-X-4). §7: fixture (2) states its line VAT 23.00 and asserts V-9 passes on it (C-X-1); fixture (3) is a `Split`-level fixture (F-X-3); the guard fixture is labelled by V-8's second shape (C-X-2); the reject case names its null `reconciliation_note` (C-X-3) and lives in the Platform rejection corpus, listed on that row (F-X-2); the permissions row asserts the argument list for both values of the constant (C-X-4 = F-X-1).

*R-EX-3 amendment of 2026-09-07 (the first bench sitting, 35 fiscal documents: header 361/365 = 98.90 %, lines 307/312 = 98.40 %, gate passed; report and traces under `tests/Sibyla.Tests.Argus/evidence/extract-v2/`). **Three length caps of §2.2, §2.3 and §2.5 were smaller than what real documents print, and each refused a whole document rather than a field**: `vat_exemption_text` s(60) -> **s(200)**, header and line (BICS #32 and #22/#23 print a 100-character Belgian self-assessment clause, Google Cloud #9 a 133-character one); `payment_terms_text` s(120) -> **s(300)** (Farminvest #34 and MEO #18 print 147); `evidence.notes` items s(300) -> **s(500)** (Stripe #15, Regus #17 and Locarent #24 wrote 302, 335 and 329). Five documents were exhausted and four more spent an attempt on these three bounds alone. The fields hold printed legal sentences and the model's own account of its derivations; V-4 exists to stop an answer carrying prose, not to fix a clause's length, and truncating what a document prints would break "as printed" everywhere else in the contract. A relaxed bound cannot turn an answer already accepted into a refused one, so the sitting's 30 scored documents stand. V-17's index base is read the same way: the spec fixes none, so a path is satisfied when it is satisfied under either base or as a `lines[]` wildcard — the ambiguity is ours, and a path that names something printed under every reading still fails. `doc_type_printed` s(60) is the one short cap no document has yet met; it is left alone.*

*Revision 9 amendment of 2026-09-08, after the R-EX-3 checkpoint (both reviewers REVISE; reports `docs/apollo-argus-extraction-v1-checkpoint-review-{contract,evidence}-260908.md`). Owner ruling **D-EX-7**: the reserve set is spent as a blind control and the spec says so instead of claiming one — §1.1 D-EX-7, §5.6, §5.7, S-10. Four clauses the checkpoint found wrong in this document rather than in the code are corrected with it: V-15’s direction, V-17’s "is null", the branch-(2) guard’s tolerance, and §8’s R-EX-3 gate list.*

*Revision 9 amendment of 2026-09-07, owner ruling D-EX-6 (after the three R-EX-3 sittings): the seven key appeals of `docs/apollo-argus-extraction-v1-key-appeals-260907.md` accepted as recommended — three corrections of §5.5, three flag rows (two of them the new `keyLinesSummarised`, whose scoring rule is S-12 below), and one instruction tightening carried to the next package build. §1.1 D-EX-6, §5.3 S-12, §5.5, §5.7.*

*Revision 9 amendment of 2026-09-07, owner ruling D-EX-5: the register fiscal-key check at the company gate and, again, as the persistence guard — §1.1 D-EX-5, the gate paragraph of §2.6, persistence item 1 of §6.*

*Revision 8, 2026-09-06: addresses round 7 (revision 7, head `64e1f89`: **feasibility ACCEPT** 0/0/2/3 — its second consecutive ACCEPT, on revisions 6 and 7 —, contract REVISE 0/1/1/4; all 19 round-6 findings closed by both and every round-6 trace re-confirmed). Every finding is dispositioned in the review record ("Author's dispositions — revision 8"; ids C-W-n and F-W-n). The changes are surgical: nothing beyond these items is touched. Status: for round 8 review by both reviewers before any code. Every design point marked **proposed** is a recommendation; every **Q-EX-n** is a question the owner rules, all of them in §1.2 as one numbered list (Q-EX-0…25; no new question this revision).*

**What changed from revision 7, by section.** §2.2: the Locarent #35 quote. §2.3: on a converted line, `total_amount` = converted net + converted VAT (the printed secondary-currency total is the V-7 check). §2.6: the branch-(2) guard reads "Σ all lines (**amended 2026-09-08, C-27: a breach of the header-equals-Σ-lines invariant is a `DPRCHK` finding in every branch, with no tolerance** — branch (3) already reported a cent, and two meanings of "equal" inside one function is how a silent hole starts. Separately, the branch-(2) guard below is compared within ± 0.02, as every neighbouring test is — amended 2026-09-08, C-12: the guard was written as exact equality, so one cent of line-level rounding defeated it and branch (2) then moved a duty already inside the net out of the header VAT, silently, because V-9’s own ± 0.02 absorbed the cent), the step-A line included, ≠ net"; branch (3) with a zero difference records no finding. §2.8: V-8 accepts both the branch-(1) and the branch-(2) shape; V-9 accepts `Σ item lines = net` or `Σ all lines = net`. §4.3: `PermissionsFile.Build(sandbox, package, releaseDir, otherReleaseDirs)` with the worker enumerating the sibling releases; `BuildArguments` adds `--verbose` after `--output-format stream-json` only when R-EX-2 says it is required. §4.6: the artifact-precondition wording. §5.2: "2 placeholder document ids". §7: golden #10 line 5 = 9.32 / 2.14 / 11.46; the guard fixture and a third-shape reject case; the permissions test's two fake siblings. §8: "4 + 18 + #31".

**What changed from revision 6, by section.** §1.2: Q-EX-20's recommendation gains the utility-bill clause. §2.2: the header `service_period` from identical line periods (Locarent). §2.3: clause (j) utility bills; lines printed only in a secondary currency converted at the printed rate (AWS); per-line VAT and net derived where not printed (MEO, Hydra, Mobilize, Locarent, Anaptyxis, Via Verde). §2.6: branch (2) guarded against a printed stamp line inside the net; "change nothing except `VAT := VAT ?? 0`". §2.7 N-7: Lari's `document_id`. §2.8: V-8 with duty and surcharge; V-9 over `item` lines. §4.2: `EXTRACT.md` rules (the document's own invoice-date field; `receipt` = SKILL.md's Invoice-Receipt; a discount column is not the VAT rate; the secondary-currency and utility rules). §4.3: the `BuildArguments` and `PermissionsFile.Build` seams; nine admitted extensions; the SCM recovery wording. §4.5/§8: probe (b) records whether `stream-json` needs `--verbose`. §4.6/§4.7/§8: one release id for web and worker; rollback wording. §4.7: the re-extract count over document-processing jobs. §5.1: #7, #16, #21 notes. §5.2/S-2: uniqueness within each statement. §5.3: S-6's R3 rule after the `DateDoc` fallback. §5.5: the #21 `dateDoc` correction. §5.7: the bench project in `Sibyla.slnx`. §7: golden #10 and the #21/#27 fixtures typed; the permissions seams.

**What changed from revision 5, by section.** §1.2: Q-EX-6 notes that the 8 `vat_rate` cells rest on the document-level-rate rule. §2.2: receipt totals (the amount paid; fees are lines). §2.3: `vat_rate` from a document-level rate or exemption; the appended stamp line's rate; clause (g) wording; clauses (h) (interest/penalty line) and the receipt rule; #12 and #13 typed. §2.6: branch (0) runs whenever `net_amount` is null and a total is printed, before the identity clause; `(vat ?? 0)` in (1)/(2); `VAT := VAT ?? 0` after the split in every branch; header = Σ lines in (0)–(2), the difference in (3) is the finding; Lari/eSIMGo/VFX named. §3 #1 aligned with S-6. §4.3: the prompt names `<sandbox>/document<ext>` with the whole path tokenised; `permissions.json` outside every working directory; `JobId` nullable; the seams `JobCompletion.CompleteAsync`, `TimeoutLaneMonitor.Record`, `CompanyGate` in the worker with its `InternalsVisibleTo`; `StartupCheckSeconds`. §4.5: the deny file's location; probe (a′) wording. §4.6: `migrate.ps1` → web → worker with health check 9; the published-tree check moves to `publish-release.ps1`. §4.7: a hold with a null result takes the fiscal branch; the statement refusal decided by `result_json.doc_type`. §5.3: S-2 occurrence order among tied rows by `bm_code` ascending in every `printOrder`; S-3 states that no header amount is null after the transform; S-6 applies the key's rule; S-9 `line_count` after `Split`. §7: fixtures retyped (#6 VAT 0.00, fixture (3), the occurrence fixture, a `.png` permission case, the hold-with-null-result case, `StartupCheckSeconds = 1`, `SkillPackageTests` narrowed).

**What changed from revision 4, by section.** §1.2: Q-EX-16's note reworded (the candidate status is fixed at upload); Q-EX-21 gains probe (a′) and the `--settings`-under-`--safe-mode` record; Q-EX-23 gains the R3 scoring consequence; Q-EX-24 says "two or more invoices"; Q-EX-25's recommendation carries the header adjustment. §2.2: an insurer's "Prémio antes de impostos" is `net_amount`; a per-rate VAT summary's column sums are the header net/VAT. §2.3: clause (f) extended to the header; clause (g) (premium breakdown block). §2.6: `Split` branches (1)/(2) test with `duty + (other ?? 0)` and adjust the header so it equals Σ lines in every branch; step C is `item.Net += other`; branch (3) never fails the document; #25 and #31 traced both ways; the SKILL.md §6 attribution of branch (2) dropped. §4.2: `EXTRACT.md` rules; long-line counts 4 / 5 / 1. §4.3: `JobId` on `ProcessingEvidence`; prior timeouts as `JobId == job.Id && ExitCode == −1`; the Hold's `jobque` row; the attempt table; the argument order; version compare by first token and one shared 10 s budget; the `CompanyGate.ApplyAsync` seam. §4.5/§8: probe (a′). §4.6: the csproj `Exclude` and the SDK citation; `SkillPackageTests` on the published tree. §4.7: `hold_reason` column, the return path from `PossibleDuplicate`, the API row reworded. §5.2: `netVatNotPrinted` dropped. §5.3: occurrence order against the key's print order; S-4 wording; S-9 without the flag, `fiscal_no` by the key's flow, R3's gate cells reported; `SameTaxId` internal. §5.7: `statementDoclog.fileHash`. §7: goldens and fixtures retyped.

**What changed from revision 3, by section.** §1.2: Q-EX-4 says the server transform includes the parafiscal fold; Q-EX-9 makes the reserve a third sitting under the frozen tuple; Q-EX-15 names the bench binary; Q-EX-16 notes the intake API's vocabulary for a held row; Q-EX-18's wording corrected (evidence per job, a numbered idempotency key); Q-EX-20 gains the POS-receipt clause; Q-EX-21 gains `--safe-mode`; Q-EX-24 (two-invoice bills) and Q-EX-25 (parafiscal surcharges) added. §2.2: `other_taxes_amount`. §2.3: doctrine clause (f); "4 X 11,99". §2.4: amount sign by printed column; Revolut sub-lines are not the description. §2.5b: the 24 DOCLOG columns classified. §2.6: `Split` rewritten — branch (0) terminal, the stamp line appended in every branch, the parafiscal fold per SKILL.md §6, #6 and #25 traced, (1)/(2) named as synthetic-fixture branches. §4.2: `EXTRACT.md` states document kind by fiscal function. §4.3: `--safe-mode`; the timeout seams (`RunAsync(…, timeoutSeconds, …)`, the prior-timeout fact in `evidence_json`, `JobOutcome.Hold`, the per-process lane counter); start-up checks in `IHostedService.StartAsync` with a 10 s cap; `ExtractionRunner(filePath, sandboxRoot, evidenceRoot, …)`; evidence files per job. §4.5: the deny list enumerated with `--restricted` as the primary control; the `--restricted` bullet reworded; the R-EX-2 probes. §4.6: both csproj lines. §4.7: the `HeldForPerson` transition table; re-extract with per-job evidence and the key `docint:<id>:process:<contract>:<n>`. §5.3: occurrence order defined; `fiscal_no` under `CompanyMatcher.SameTaxId`; the fold in S-3. §5.5: 18 = 15 + 2 + 1 with the corrected BPI quote; the #31 key correction. §5.6: R2/R3 replaced. §5.7: the bench binary, sandbox and evidence root, the skill-build clean post-condition, three sittings. §7: synthetic split fixtures with figures; re-extract evidence assertions; golden #2 at VAT groups; `SkillPackageTests` path source. §8: R-EX-2 probes.

**What changed from revision 2, by section.** §1.2: Q-EX-7 says the movements gate goes beyond the ruling; Q-EX-13's recommendation switches to a separate `CapturedAt`; Q-EX-15 names the bench account and the full model id; Q-EX-18 states the re-extract mechanics; Q-EX-21's recommendation is the full CLI flag set; Q-EX-22 (CLI transcripts) and Q-EX-23 (intercompany ownership at the gate) added. §2.3/§2.6: the stamp-tax line keeps the printed sign on invoices and is negative on credit notes, appended as `line_no = n + 1`; the split is a function on contract fields with a no-net branch; the both-match gate rule. §4.1: zip size stated as uncompressed. §4.3: one 900 s timeout, no kind hint, retry at 1.5 × only on a second timeout, the lease rule dropped (renewal covers it), `CliVersion` and the full model id enforced at start as a host-stopping failure, `--fallback-model` never passed, the full production flag set. §4.5: the flag set, a web-egress hostile document, the Windows path-rule syntax as an R-EX-2 item. §4.6: the built package committed and shipped as csproj Content; `--no-session-persistence` as a retention rule. §4.7: `IntakeProcessingStatus.HeldForPerson`; re-extract mechanics; the gate runs on held rows. §5.2: hand-keyed `printedOpeningBalance`/`printedClosingBalance`, `netVatNotPrinted`, `printOrder` gains `sectioned`, the DateDue note count 5 + 2. §5.3: S-2 pairs on (date, amount, currency) with S-11 as tie-break; S-7 scores balances against the printed flags, never `bnkchk`; statement cells belong to the movements score; S-9 uses `netVatNotPrinted`. §5.4/§5.7: the bench builds the company list from the keys and never opens a connection string; the bench identity is the owner's. §5.5: the 18 defective key descriptions pre-declared. §5.6: `reserve-set.csv` names the doclog codes. §7: the Revolut fixture carries an FX sub-line row; #29 in the gate tests; `HeldForPerson` in the page test. §8: R-EX-2/R-EX-3 items.

**What changed from revision 1, by section.** §0: Q-EX-0 (the "section 5" reading). §1.2: one numbered list, Q-EX-0…21, with the reviewers' additions. §2: `date_doc` fallback; `payment_proof` replaces `date_pay`; header amounts and stamp duty **as printed** (the server applies the split); `transaction_date` on movements, `DocDate = embedded ?? transaction ?? posting`; movements capped at 150 with a held-for-a-person path; `summary` length; placeholder list → `null`. §3: #6, #8, #10, #14, #15 rewritten. §4: commit subject corrected; exact schema.md ranges; reflow of long lines recorded in `manifest.json`; `CLAUDE.md`/`.claude` refused; whole-tree fallback struck; `.md` rules only; per-kind timeouts; model and effort pinned and recorded; bench on `stream-json`; path-scoped `Read` with denies; new §4.6 deployment/rollback and §4.7 the worker and web path in this slice (gate and review page by contract id, corrections stamp the source contract, re-processing, dead-letter interim, `MaxAttempts`). §5: the 40 JSON answer keys adopted as the versioned oracle with a flags file; movements paired by natural key; `service_period` on R1 rows only and `account_period` under the key's own stamp; `date_due` null accepted only where the key flags an assumption; magnitude sign rule; `DatePay` derived; gate 95 % per kind, per-field floor only at n ≥ 20; balances scored against `prints_*` flags; description by normalised overlap ≥ 0.9; bank-statement header cells excluded; the gate scored only where an id is printed; ten reserve documents named; pre-declared corrections; bench as a console project outside `local\test.ps1` with a resume plan. §6: cash-delta and direction mapping, the sync-era refusal, the computed-balance fallback. §7: one path id (`extract-v2`) for goldens and evidence; the new tests. §8: release order web → worker.

## 0. Purpose and scope

The worker today runs an inline prompt under contract `sibyla.extract.v1` (`src/Sibyla.Platform.Infrastructure/Ingestion/ExtractionContract.cs`, 11 header fields) and `ProcessingEvidence` hashes the prompt text. A gateway or upload document therefore gets a header and no lines, no service period, no bank movements. The owner ruled that the next contract is the Invoice Skill Build's field list, unchanged, with the skill tree packaged at a pinned commit and scored at 95 % field-level exact match on a 40-document sample before it opens to gateway traffic.

**In scope of this contract (the model's answer, validated at the trust boundary):** invoices, invoice-receipts and credit notes — header identities and amounts as printed, dates, the stated service period, the lines with item candidates; bank and card statements — the account identity, the statement balances, every movement; the evidence the answer stands on.

**Out of scope of this contract (named so nobody looks for them here):** resolution (entity, item, EICode, PLMKEY/PLMKO, Company/Entity codes, FlowType, OriginClass, AccountPeriod, Period, FEX/LocalAmount, DateDue/DatePay inference, the stamp-duty reclassification) — all derived server-side (§2.6, §6) under the FDR's procedures; persistence into FDCHDR/FDCDTL/BNKMOV and the correction form's lines section (§6); FlowType P/F/O documents, payment notices, collection notices, cancelled invoices, tax documents (`doc_type: other` with the printed title, routed to review as today); the channel-intake API (unchanged by the owner's word).

**The reading this spec is built on (Q-EX-0).** `SKILL.md` §5 ("Document classification", lines 95–155 at the pinned commit) carries no field list; the columns the ruling can mean are `Specs\Data Schema\schema.md`: FDCHDR (32), FDCDTL (18), BNKMOV (26), DOCLOG (24). §2 maps every one of those columns to *extracted*, *derived later* or *system*, so "unchanged" is a checkable claim. The owner confirms or corrects that reading before code.

## 1. Owner decisions

### 1.1 Ruled 2026-09-05 and 2026-09-07 (transcribed, binding)

| # | Ruling |
|---|---|
| D-EX-1 | Contract v1 = the Invoice Skill Build's field list, unchanged: lines with item candidates, the stated service period (R1), the origin class, the bill-to and issuer fiscal identities for the company gate, bank-extract movements. |
| D-EX-2 | The skill tree is packaged at a pinned commit; the worker hands it to the Claude CLI; `ProcessingEvidence` hashes the tree, not an inline prompt. Pinned commit (§4.1): `a558523f3f0ad97e6c3f60707d635b3d257d3392`. |
| D-EX-3 | Sample set and measure: 30 invoices + 5 credit notes + 5 bank extracts from the FDR corpus, the FDR's stored values as the answer key, field-level exact match on header and lines ≥ 95 % before the contract opens to gateway traffic. Order after Slice 2 E2 closes: extraction → line and bank-movement resolution under the P2-05 rules → persistence + the lines section of the correction form. |
| D-EX-4 | **2026-09-07 01:25 UTC, the owner: "Accept all 26 recommendations."** Q-EX-0 to Q-EX-25 are ruled exactly as the recommendation column of §1.2 states them (revision 8, the head both reviewers accepted); §1.2 stays as the record of each question and its alternative. In particular: the movements gate at 95 % stands (Q-EX-7); the intake API keeps its vocabulary and the v2 page ships in the same release as the worker (Q-EX-16); the issuer's company owns an intercompany row as R / Internal (Q-EX-23); the first-printed invoice answers a multi-invoice bill (Q-EX-24); the parafiscal fold is the server's (Q-EX-25); no session persistence from v2 on and the existing transcripts under the worker's CLI home are purged by the owner on the host (Q-EX-22). |
| D-EX-5 | **2026-09-07 ~11:05 UTC, the owner: the register duplicate is detected at the company gate** ("ok. do it", after the assessment of the morning's case). The case: the owner uploaded `Gott_Invoice_BICS_202601_01.pdf` at 09:37 UTC without a company; extraction returned 851301 / 175.16 EUR / issuer BE 0866.977.981; the gate assigned GOTT; the register already held the document as `I26010021` (archived as `5581529_851301.pdf`), and the intake became Processed beside it, unflagged — no path compares an intake against the register, and the bytes differ from the archive copy, so no checksum scope would have caught it. **Ruling.** (1) The checksum control at upload stays as ruled on 2026-09-01 and 2026-09-04: licence-wide while the intake has no company, per company once it has one; it catches identical bytes only. (2) A **fiscal-key check** is added where the key first exists: in the company gate, immediately after the assignment (and on `HeldForPerson` rows, as the gate itself runs there) — the register (`fdchdr`) is looked up by `company_id`, the issuer fiscal number (normalised as `CompanyMatcher.Normalize` / `SameTaxId`, matched against the entry's `entmst.fiscal_no`) and `document_number`; a match holds the intake as `PossibleDuplicate` **of that register entry**, never processed further, ruled by a person from the Uploads page with the buttons the checksum duplicates already use. "Not a duplicate" records a **verified genuine repeat** in the register's own vocabulary (`verified_genuine_repeat`), never a bare override; "duplicate" archives the intake pointed at the entry. (3) The same lookup runs **again in the persistence slice**, on the corrected values, as the last guard before `DocumentEntryService.EnterAsync`: a match is a hold, never an entry. **Needs:** a reference from `docint` to a register entry beside `duplicate_of_id` (column named by the slice that adds it), the audit detail naming the entry code, §4.7 transitions gaining the register branch. **Lands in the extraction track:** G3's hold transitions carry the gate branch; the persistence slice carries the guard. No change to the deployed release was made on this ruling. |
| D-EX-6 | **2026-09-07, the owner: "accept all seven recommendations"** — the appeals sheet `docs/apollo-argus-extraction-v1-key-appeals-260907.md`, written after the three R-EX-3 sittings passed (fiscal header 99.07 % / lines 98.47 %, statements movements 96.04 %, reserve movements 100.00 %). **A-1** I26020038 `document_type`: the key stands (the page is titled `EXTRATO/RECIBO` but prints a clearance condition and no payment date); what is wrong is our own instruction, which lists a `Recibo` title as proof of payment *and* defines a receipt as the document that proves its own payment — tightened at the next package build, not here. **A-2** I26030019 `documentId` `PSRS2` → `NCPSRS2` (the page prints `NC PSRS/2`). **A-3** I26050003 `fiscalNo` `GB12465777` → null (a UK company registration number, which §2.2 says is not a tax id). **A-6** I26070026 `documentId` `590798` → `1254765069` (the document is a payment receipt printing its own number; the invoice it pays stays in `related_document_ids`). **A-4** I26070007 and **A-5** I26080031: the key’s line list is a *summary* of what the page prints — one rolled-up row against seven printed lease components, and a dropped zero-value row — so those two carry the flag `keyLinesSummarised` and are scored by S-12. **A-7** I26010042: the `Data vencimento` column is printed empty, so the flag `dateDuePrinted: false` applies and S-4 accepts the null answer; a flag row, not a correction. The three reserve documents had no flag row before this ruling under the original §5.6 seal. These answer-informed amendments and the subsequent rerun ended its held-out status (D-EX-7: no fresh set for v1); each change is dated and attributed, and none provides blind validation. |
| D-EX-7 | **2026-09-08, the owner: "fix the wording, no fresh set."** The R-EX-3 checkpoint’s Critical finding: §5.6 calls the reserve "the third, **single** sitting" and S-10 says it is "**run once**", and it was not. Its ten documents were read at 16:13 on 2026-09-07 (report `score-20260907-1613-dff90f9-a558523`); ruling D-EX-6 then wrote three flag rows and one correction row **about reserve documents, on the strength of having read their answers**, and added rule S-12; the documents were read again at 22:50 (`score-20260907-2250-e2f02e3`). The second run’s 100 % is a second read scored against a key fitted to the first. The blind run’s own numbers, recomputed from the surviving report under S-1 as corrected here, are **header 76/80 = 95.00 %, lines 27/51 = 52.94 %, movements 158/158 = 100 %** — the lines rate is a hard fail, and the report of that run nevertheless printed "Gate (S-10): PASSED" because of the tally defect the same checkpoint found. Its evidence is unrecoverable: the run folder was destroyed by a careless wildcard on 2026-09-07 and was never in git. **Ruling.** The slice has **three honest measured sittings and no held-out result**, and says so; the reserve set is spent and is not run again for this contract; no fresh sealed set is built for v1. A held-out measurement, if one is wanted, is a question for the persistence slice with a set sealed before it is read. Nothing about sittings 1 and 2 changes: they were always tuning sittings by §5.7, and their numbers stand. |

### 1.2 The 26 questions — ruled 2026-09-07 as recommended (D-EX-4); each with the recommendation this revision is written to

| # | Question | Recommendation |
|---|---|---|
| Q-EX-0 | **"Section 5" = the four schema.md column lists?** SKILL.md §5 has no field list; this spec reads the ruling as FDCHDR/FDCDTL/BNKMOV/DOCLOG columns of `schema.md`, classified in §2. | Confirm that reading. |
| Q-EX-1 | **Wire id.** `sibyla.extract.v1` is taken. | `sibyla.extract.v2` — one namespace, monotonic, matches `sibyla.channel-intake.v1`; rows under v0/v1 keep their ids. |
| Q-EX-2 | **What the CLI receives.** The full tree (1.43 MB) fits no context; SKILL.md alone exceeds the CLI `Read` line limit. | The excerpt of §4.2, built by a script from `git archive <commit>` with long lines reflowed and the reflow recorded; files and sections are *selected*, no word edited. No whole-tree fallback. |
| Q-EX-3 | **Origin class** — asked of the model or derived? | Derived server-side from the two fiscal identities against the licence's companies (§2.6); scored as a derived field where the document prints an id. |
| Q-EX-4 | **Stamp-duty reclassification** (SKILL.md §6: its own line, header Net += duty, VAT excludes it; a parafiscal surcharge folds into the item line) — model or server? | **Server** (changed from revision 1 on both reviewers' finding): the model returns the printed header figures plus `stamp_duty_amount`, `other_taxes_amount` and any printed stamp-tax line; the server and the scorer apply the identical deterministic transform (§2.6), **which includes the parafiscal fold of SKILL.md §6** — the pinned skill's own rule, so "the transform the FDR runs" is what the keys hold. "As printed" holds everywhere in the contract. |
| Q-EX-5 | **Signs.** Credit notes are stored negative; some documents print negatives (a −0.03 stamp line on a positive invoice). | Contract = printed sign, verbatim. Scorer and persistence compare and store `sign_by_kind × \|value\|` per line kind and document kind (§5.3 S-3), so a credit note printing negatives is never double-negated. |
| Q-EX-6 | **Quantity / UnitPrice / VATRate in the 95 %.** The key holds them on 6 / 6 / 8 of 109 lines — blank because uncaptured, not unprinted. | Score only where the key holds a value; report fill rate separately; no hand-keying for v1. Note: the 8 scored `vat_rate` cells (Avis's six lines under "VAT @ 0%" in the VAT summary; #25's two lines under "Isento de IVA", one of them the server-appended stamp line) rest on §2.3's rule that a **document-level** rate or exemption is the `vat_rate` of every line and that the appended stamp line takes `vat_rate = 0` — none of the eight prints a per-line rate. |
| Q-EX-7 | **Threshold shape.** The ruling (plan line 822) names "header and lines"; a movements gate is this spec's addition. | **95 % per document kind** (invoices+credit notes header cells; line cells; movement cells including the statement cells — three gates, each ≥ 95 %); a per-field floor of 85 % applies only to fields with ≥ 20 scored cells, smaller fields are reported. **The owner confirms the movements gate**, which goes beyond the ruling's words; without it, movements are reported only. (Changed from revision 1: the aggregate was movement-dominated and the floors hit 6-cell fields.) |
| Q-EX-8 | **Where the answer key lives.** Real business data. | In the repo under `tests/Sibyla.Tests.Argus/golden/extract-v2/answer-keys/` (private GitLab): the 40 JSON keys already built on 2026-09-06 (§5.2), versioned as the oracle. |
| Q-EX-9 | **Reserve documents.** | The ten named in §5.6 (R2/R3 replaced in revision 4, Q-EX-24), fixed now, opened once — as a **third, single bench sitting under the frozen tuple at R-EX-3**, never during the fiscal/statement tuning sittings of §5.7. **Amended 2026-09-08 (R3-9): the seal did not hold and this row must not imply it did.** The set was opened once, then its keys were amended on the strength of what that opening showed, then it was opened again — ruling **D-EX-7**. It is a measured result, not a held-out one, and §5.6 and S-10 say so. |
| Q-EX-10 | **Bank statements and DOCTYP.** `DT000020 Bank Statement / External = Exclude` lands a statement in DOCFAI today. | A `bank_statement` branch in `DocumentCaptureService` (DOCLOG row + BNKMOV import, never DOCFAI), DOCTYP unchanged. |
| Q-EX-11 | **Answer-key fiscal identity.** Revision 1 asked to re-cut on `fdchdr.fiscal_no`. | **Closed by evidence, no ruling needed:** on the 40 keys `fdchdr.fiscal_no == entmst.fiscal_no` on every row, and the JSON keys carry `fiscalNo` from `fdchdr`. The rule (captured value is the key) stays written for the reserve and any later set. |
| Q-EX-12 | **Reconciliation mismatch = retry or review?** | Unexplained (`reconciliation_note` null) = validation failure; explained = accepted, DPRCHK finding in the persistence slice (V-12). |
| Q-EX-13 | **`Doclog.DocDate` for Apollo-native rows.** The FDR's DOCLOG `Date` was capture-time (11 of 35 keys have `doclog.docDate ≠ dateDoc`); Apollo's `CaptureFacts.DocDate` is required. One column, two meanings today. | **`CapturedAt` as its own column** on `doclog`, and `DocDate` = the document's date (`header.date_doc ?? header.date_due`; a statement's `period_end`) for every Apollo-native row; synced rows keep the FDR's value in `DocDate` with that meaning recorded on the entity until cutover, when the sync's last run resolves it. (Changed from revision 2 on the contract reviewer's note: the earlier recommendation kept one column with two meanings, which is what M9 objected to.) |
| Q-EX-14 | **Does a CLI, model, effort or package change reopen the gate?** | Yes: any change of CLI version, model, effort, package hash or contract id re-runs the bench (reserve included) and the hostile run before that configuration serves gateway traffic; the evidence names the configuration (§4.6). |
| Q-EX-15 | **Model, effort, plan and the bench account.** Nothing pins the model today; the 95 % is not reproducible without it; the bench cannot use the production login (§8). | `WorkerOptions.Model` = the **full model id** read from the first bench run's `modelUsage` (not a default alias, which drifts), `WorkerOptions.Effort` = the value the bench passed with (`--effort` on CLI 2.1.259), both passed on every run and recorded per attempt; `--fallback-model` is never passed. The bench runs under a **bench `CLAUDE_CONFIG_DIR` and login owned by the owner** (named and recorded in the score report) and **on the pinned binary `C:\Apps\Sibyla\tools\claude\claude.exe`** (`ClaudeCliPath` set explicitly — never the npm fallback of `ResolveCliExecutable`), refusing to start on a `CliVersion` mismatch exactly as the worker does; the identity does not change the configuration tuple of §4.6. The plan is the existing Claude subscription (D12); the bench plan of §5.7 fits its 5-hour window. |
| Q-EX-16 | **Web in this slice.** A v2 result renders blank on today's review form; a dead-lettered statement has no human completion path until the lines section (§6.3). | This slice ships a **v2-aware review page** (§4.7: header fields mapped, lines and movements read-only with the raw JSON, corrections stamped with the source contract), released **before** the worker; statements that dead-letter are held for a person with their evidence — no completion path until §6.3, stated on the page. **Intake API note:** the channel-intake API keeps its vocabulary (the owner ruled it unchanged); a candidate's status is **fixed at upload as `completed`** (`ChannelIntakeService` sets it from the upload outcome and never re-reads `docint`), so a later hold does not reach the API by construction — the hold is visible on the Uploads page only; the alternative is a new candidate status in a later API revision. |
| Q-EX-17 | **Card-statement `DocDate`** = the printed "DATA DA TRANSACÇÃO" column (the FDR's `build_bnkmov.py`), not an embedded date. | Yes — `transaction_date` in the contract; `DocDate = embedded_date ?? transaction_date ?? posting_date` (§2.4). |
| Q-EX-18 | **Re-processing of v0/v1 rows.** | Not automatic. A person may "re-extract under v2" from the Uploads page: a new queue job with idempotency key `docint:<id>:process:<contract>:<n>` (n = the count of existing document-processing jobs for the intake + 1, so a dead-lettered v2 job can be re-run); on success `result_json` **is replaced** (the completion path overwrites it), the previous answer surviving **in its own job's evidence folder** `<staging dir>/evidence/<jobId>/attempt-N-result.json` (nothing is overwritten, §4.3) and as its element of `evidence_json`; an existing `CorrectedJson` is **kept with its own contract stamp and shown as superseded** on the page until a person corrects again; nothing is re-run in bulk (§4.7). |
| Q-EX-19 | **Tenant #1 content in the package.** The selected SKILL.md sections carry a NIF example, company names and two private individuals' names; every tenant's run would read them. | Ship the excerpt **unscrubbed but recorded** — the ruling is "unchanged" and the content is the skill's own examples — except personal names, which the build script masks (`<name>`) and records in `manifest.json`. The reviewers may hold out for a full scrub. |
| Q-EX-20 | **Line doctrine for summary-plus-detail bills** (MEO: the summary page prints one line; the key's 8 lines are the detail section's category subtotals). | Itemise a detail section's **category subtotals**, never per-subscription/per-call rows; summary-only when no detail section exists; an aggregator's sub-invoices are lines (Via Verde); **a POS receipt with a VAT summary is itemised at its VAT-rate groups** (net, VAT, total from the summary block — Continente: 2 lines), product rows and discounts summarised in a note (clause (f), §2.3); **a utility bill (water, electricity, gas) is one `item` line per invoice** — its "Total sem IVA" / VAT / total — with the consumption, tariff, availability and tax rows summarised in a note (clause (j); Águas do Porto and EDP: 1 line each). Written into `EXTRACT.md`. |
| Q-EX-21 | **The CLI's tool and permission set.** `--allowedTools Read` is unscoped and leaves Bash, WebFetch, WebSearch and MCP in the tool set; the CLI runs as `.\SibylaWorker` with `SIBYLA_SECRETS_FILE` and `CLAUDE_CONFIG_DIR` in its environment. | The production flag set of §4.3: `--tools Read --restricted --safe-mode --strict-mcp-config --disable-slash-commands --permission-prompts none --settings <per-job deny file> --no-session-persistence`, plus `--add-dir <jobDir>` and `--add-dir <package>`; `--restricted`'s working-directory confinement is the primary control and the deny file (§4.5, enumerated) the second; the hostile run includes an out-of-sandbox read and a web-egress document; every evidence file is scanned for secret markers before the run is accepted; the Windows syntax of the path rules is verified on the pinned CLI at R-EX-2 by probe (a′) — a file planted **inside** the sandbox and denied by rule must be refused while `document.pdf` reads — beside probe (a) (the sibling `appsettings.json`, refused by `--restricted`'s confinement) and probe (b) (the planted `CLAUDE.md` under `--safe-mode`); R-EX-2 also records whether `--settings` still applies under `--safe-mode` — if not, `--safe-mode` leaves the set by amendment and probe (b) stands on `--restricted` alone (§4.5). |
| Q-EX-22 | **CLI session transcripts.** The worker's CLI persists every session — tool results, i.e. each document's full text — under `CLAUDE_CONFIG_DIR` = `D:\ApolloData\worker-claude\projects\…`, indefinitely; today's worker already does this. | `--no-session-persistence` in production and in the bench from v2 on, stated in §4.6 as a retention rule; **and** purge the transcripts that already exist under `D:\ApolloData\worker-claude\projects` — the purge is an owner action on the host (this spec and its work never read that directory). |
| Q-EX-23 | **Intercompany documents at the gate.** When issuer and recipient both match licence companies (#29 R26030003: Gott issues to Itoorer), `docint.company_id` holds one company. Which book does the intake row land in, or does it triage? | **The issuer's company owns the row as R / Internal** (the FDR's practice on #29, stored Company GOTT / R / Internal; SKILL.md §11 "the registry tracks the business from one entity's perspective at a time"), with both candidates recorded in the audit detail (`document.company.inferred`, reason "intercompany: issuer owns"); the counter entry is the persistence slice's. Alternative: triage with both named and no company cell scored. **Consequence the owner sees:** the FDR books both legs of an intercompany document, one per book; Apollo answers one. Reserve row R3 (I26070074, the same Gott → Itoorer document on Itoorer's book, key Company ITOO / flow I) therefore cannot match under the recommendation — its `company`/`origin_class` cells are reported, not scored (S-9). |
| Q-EX-24 | **Bills carrying two or more invoices.** One PDF can print two or more invoices, each with its own ATCUD (#21 Águas do Porto: two; #27 EDP: four — 32.23, CAV 3.02, 0.21, 0.01 — plus a 1.50 item that "não serve de fatura", under a printed "Quanto tenho a pagar 36.97"); the contract returns one `header`, and the FDR booked each invoice as its own row. | **The answer is the first-printed invoice** (by ATCUD/number order): `document_id` decides the key row, `total_amount` is that invoice's total (#27: 32.23, not 36.97), `evidence.notes` names the further invoices; the reserve twins R2/R3 leave the reserve and are replaced (§5.6). Alternative: an `additional_documents[]` array in a later contract, one row per further invoice. |
| Q-EX-25 | **Parafiscal surcharges (INEM/FAT/ANPC).** #25 prints premium 382.82, stamp 19.15, "Outros encargos e taxas" 9.57, total 411.54; the FDR's key line 1 is 392.39 = 382.82 + 9.57 (SKILL.md §6: the surcharge "folds back into the original line's NetAmount"). #31's key stamp line −17.75 = 12.38 stamp + 5.37 surcharge contradicts that same rule. | **The server folds `other_taxes_amount` into the item line per SKILL.md §6** (§2.6 step C: `item.Net += other`, into the single item line or the largest, flagged) **and adjusts the header by the same amount** (branches (1)/(2): `Net += duty + other`), so the stored header equals Σ lines on a printed-net insurer document — the pinned skill's rule, so the transform is the FDR's; #31's key is **corrected** (stamp line −12.38, item line −143.02) as a pre-declared row (§5.5). Alternative (the feasibility reviewer's): exclude #25's and #31's header-net and line cells by flag for v1 and rule the fold with the persistence slice. |

## 2. The contract — `sibyla.extract.v2` (proposed id, Q-EX-1)

### 2.1 Shape

One JSON object, exact member set at every level (an unexpected member fails validation by name, as today), fixed canonical serialisation from the values that passed. Numbers are JSON numbers; strings carry no control characters; dates are `YYYY-MM-DD`; amounts are in the document's currency at most 2 decimals; **`null` means "not printed"** — never an empty string, never 0 as a stand-in. Everything the model returns is **as printed**; every inference is the server's (§2.6).

```json
{
  "contract": "sibyla.extract.v2",
  "doc_type": "invoice | receipt | credit_note | bank_statement | other",
  "doc_type_printed": "Fatura-Recibo",
  "summary": "one sentence, ≤ 500 chars",
  "header": { ... §2.2 ... },            // null only when doc_type = bank_statement
  "lines": [ { ... §2.3 ... } ],         // [] when doc_type = bank_statement or other
  "statement": { ... §2.4 ... },         // null unless doc_type = bank_statement
  "movements": [ { ... §2.4 ... } ],     // [] unless doc_type = bank_statement
  "evidence": { ... §2.5 ... }
}
```

`doc_type` keeps today's vocabulary because `DocumentTypeRouter.DocumentTypeFor` maps it to DOCTYP in one place (`receipt` → `Invoice-Receipt`). `doc_type_printed` (≤ 60, nullable) is the document's own title, so a person can re-route an `other`.

### 2.2 Header — every FDCHDR column accounted for

Columns from `schema.md` FDCHDR (32): `EntryCode, FlowType, Company, Entity, FiscalNo, Period, AccountPeriod, DocumentID, DateDoc, DateDue, DatePay, ItemDesc, ItemCode, EICode, PLMKEY, PLMKO, NetAmount, VATAmount, TotalAmount, Currency, FEX, LocalAmount, Filename, ManualEntry, AutoEntry, DataSource, EnteredBy, EnteredAt, HammerFlag, ICPairID, CounterEntryCode, Flag / Review Notes`. Apollo's entity (`src/Sibyla.Modules.Argus.Domain/Entities/Documents.cs`) adds `CounterpartyNamePrinted, AccountPeriodRule, AccountPeriodEvidence, FexStatus, SourceKey, SourceBmCode, SourceSystem`.

**Extracted (the `header` object).** `s(n)` = string ≤ n chars, `d` = decimal, `date` = ISO date, `?` = nullable.

| Field | Type | FDCHDR column | Rule | Scored (§5.3) |
|---|---|---|---|---|
| `issuer.name_printed` | s(200) | `Entity` (I) / `Company` (R), resolved later | verbatim, the legal/invoicing party per SKILL.md §3 | no |
| `issuer.tax_id_printed` | s(64)? | — | verbatim | no |
| `issuer.tax_id` | s(32)? | `FiscalNo` on I rows | N-3; placeholders → `null` (N-7) | yes (I rows) |
| `issuer.country` | s(2)? | — | ISO-2 when evident | no |
| `recipient.name_printed` | s(200)? | `Company` (I) / `Entity` (R) | verbatim | no |
| `recipient.tax_id_printed` | s(64)? | — | verbatim | no |
| `recipient.tax_id` | s(32)? | `FiscalNo` on R rows; the gate on I rows | N-3, N-7 | yes (R rows; the gate where printed, S-9) |
| `recipient.country` | s(2)? | — | | no |
| `document_id_printed` | s(64)? | — | verbatim | no |
| `document_id` | s(64)? | `DocumentID` | N-2; `null` when none is printed (eSIMGo) | yes |
| `date_doc` | date? | `DateDoc` | the issue date as printed; `null` when none (VFX prints only a due date) — the server falls back per §2.6 and flags | yes |
| `date_due` | date? | `DateDue` | **printed only** ("vencimento", "pay by"); never `+30`, never `= date_doc` by rule | yes (S-4) |
| `payment_proof.kind` | `receipt_title` \| `paid_statement` \| `zero_balance` \| `payment_method_confirmed` \| `none` | → `DatePay` (derived) | the evidence SKILL.md §5/§7 accepts as proof of payment; `none` on a plain invoice | derived (S-5) |
| `payment_proof.printed_date` | date? | — | a payment date the document prints, when any | no |
| `service_period.start` / `.end` | date? / date? | → `AccountPeriod` via R1 | the period the document says it bills; month-only → first and last day; **when the header prints no period and every line prints the same one, the header period is that period** (Locarent #24: "Prestação nº 74 (01/08/2026 - 31/08/2026)" on all seven lines; #35: "Prestação nº 73 (01/07/2026 - 15/07/2026)" on its seven); `null` when none is stated anywhere | yes on R1 rows (S-6) |
| `service_period.text` | s(120)? | `AccountPeriodEvidence` | the quoted words | no |
| `related_document_ids` | s(64)[] ≤ 5 | — (credit note → the invoice it reverses) | N-2 each | no |
| `currency` | s(3) | `Currency` | ISO 4217 | yes |
| `net_amount` | d? | `NetAmount` (after the server's split) | **as printed**: the document's current-period net. An insurer's **"Prémio antes de impostos" is the printed net** (#25: 382.82; #31: 137.65). On a document printing a per-rate VAT summary and no single net figure (a POS receipt, #2) it is the **summary's net column sum** (60.55) — clause (f). `null` only when nothing of the kind is printed (#6 prints only a gross) | yes (S-3) |
| `vat_amount` | d? | `VATAmount` (after the split) | as printed; on a per-rate summary the VAT column sum (#2: 13.56); `null` when none | yes |
| `total_amount` | d | `TotalAmount` | the document's own current-period total, not a carried balance; **on a receipt, the amount paid** (Alibaba #13: "Amount paid USD 1,316.23", not the "Order total 1,278.00") — fees charged on the document are lines, and `net_amount = total − VAT` when the printed subtotal excludes printed fees (clause (i), §2.3) | yes |
| `stamp_duty_amount` | d? | → the `stamp_tax` line (server) | printed "Imposto do Selo"; `null` when none | consistency (V-10) |
| `other_taxes_printed` | s(120)? | → Flag | a parafiscal surcharge (INEM/FAT/ANPC) named, as printed | no |
| `other_taxes_amount` | d? | → folded into the item line (server, Q-EX-25) | the surcharge's printed amount (#25: 9.57; #31: 5.37); `null` when none | consistency (`Split`, §2.6) |
| `reverse_charge` | bool | — | the document says the recipient accounts for VAT | no |
| `vat_exemption_text` | s(200)? | — | as printed (a printed exemption clause is a legal sentence, not a code: BICS #32 prints 100 characters — R-EX-3 amendment of 2026-09-07) | no |
| `payment_terms_text` | s(300)? | — | as printed (a printed terms sentence; s(300) by the R-EX-3 amendment of 2026-09-07) | no |
| `reconciliation_note` | s(300)? | → DPRCHK finding | non-null only when the document's own figures do not reconcile (V-12) | no |

**Derived later, not in the contract.** `Company`, `Entity`, `FlowType`, `OriginClass` (the gate); `Period`; `AccountPeriod` + rule + evidence (the ladder); `DateDue`/`DatePay` inference; `ItemDesc` (curated); `ItemCode`, `EICode`, `PLMKEY`, `PLMKO` (P2-05); `FEX`, `LocalAmount`, `FexStatus`; the stamp-duty split; `FiscalNo` = the counterparty's id by flow. **System.** `EntryCode, Filename, ManualEntry, AutoEntry, DataSource, EnteredBy, EnteredAt, HammerFlag, ICPairID, CounterEntryCode, Flag / Review Notes, SourceKey, SourceBmCode, SourceSystem`.

### 2.3 Lines — every FDCDTL column accounted for

Columns (18): `EntryCode, FlowType, CodeName, DateDoc, DocumentID, ItemDesc, ItemCode, EICode, PLMKEY, PLMKO, Quantity, UnitPrice, NetAmount, VATAmount, VATRate, TotalAmount, Filename, Flag / Review Notes`. Header copies are not per-line facts; `ItemCode, EICode, PLMKEY, PLMKO` are resolution; `ItemDesc` is curated.

| Field | Type | FDCDTL column | Rule | Scored |
|---|---|---|---|---|
| `line_no` | int | (array position) | 1..n, contiguous, document order | pairing key (S-2) |
| `kind` | `item` \| `stamp_tax` | `ItemDesc = "Stamp Tax"` | `stamp_tax` only when the document itself prints stamp duty **as a line**; a stamp amount printed only in the totals block or a footnote (#6's "(*) … −0,03") goes to `header.stamp_duty_amount` with its printed sign and the **server** creates the line, appended as `line_no = n + 1` (Q-EX-4). Sign: on an invoice the `stamp_tax` line keeps the printed sign of the duty (#6: −0.03); on a credit note it is negative (#31) | no |
| `description_printed` | s(500) | → `ItemDesc` (curated later) | verbatim wording, whitespace collapsed | no |
| `item_candidates` | s(60)[] ≤ 3 | → `ItemCode` via ITMALS/ITMMST | **definition (ambiguity #2):** 0–3 short plain-language labels in the FDR's ItemDesc style, proposed from the line's wording *and only from it*; never a code, never an entity name | hit rate reported (S-8), not gated |
| `quantity` | d(≤ 6 dp)? | `Quantity` | as printed; **0 is a fact, `null` is "not printed"** (P2-05b) | where the key is non-null |
| `unit_price` | d(≤ 6 dp)? | `UnitPrice` | as printed, plus `unit_price_basis` | where the key is non-null (server converts gross → net before comparing) |
| `unit_price_basis` | `net` \| `gross` \| `unknown` | → Flag | whether the printed unit price includes VAT (Continente's "4 X 11,99" is gross) | no |
| `net_amount` | d | `NetAmount` | printed sign, verbatim; zero-amount lines are lines. **Derived only where not printed per line** (with a note in `evidence.notes`): `net = total − vat` when only a VAT-inclusive total and its VAT are printed (Via Verde: "Total em Portagens 4,05 / IVA incluído 0,76"); **a line table printed only in a secondary currency** with the conversion rate stated is converted per line at that rate, rounded to 2 dp, into the document's currency, flagged "converted at printed rate" (AWS #10: 509.01 USD → 439.48 EUR at 0.86340951809; the header stays as printed; V-9's ± 0.02 absorbs the rounding, Σ net 448.87 vs 448.88). **On a converted line, `net_amount` and `vat_amount` are each converted at the printed rate and `total_amount` = converted net + converted VAT** — the printed secondary-currency total is not converted separately; it is the V-7 check (AWS line 5: 10.80 / 2.48 / 13.28 USD → 9.32 / 2.14 / **11.46**, not 13.28 × rate = 11.47) | yes (S-3) |
| `vat_amount` | d | `VATAmount` | 0 on exempt / reverse-charge lines. **Derived only where not printed per line** (with a note): `vat = net × the document's single rate` (or the rate printed on the line), rounded per line — MEO, Hydra, Mobilize, Locarent, Anaptyxis are the cases (MEO's Σ line VAT 700.69 vs header 700.68 sits inside V-9's ± 0.02) | yes |
| `vat_rate` | d(≤ 2 dp) 0–100? | `VATRate` | **ambiguity #4:** the rate the line prints — `0` when it prints 0 % / "Isento" / a 0 % reverse-charge line; **a single document-level rate or exemption ("VAT @ 0%" in a VAT summary, "Isento de IVA", reverse charge, "VAT - Self-settlement 0%") is the `vat_rate` of every line**; `null` only when neither the line nor the document prints a rate. The server-appended stamp line takes `vat_rate = 0` (§2.6 step A). Never `vat/net` | where the key is non-null |
| `vat_exemption_text` | s(200)? | → Flag | as printed ("M07", "Art. 9", or the whole clause — s(200) by the R-EX-3 amendment of 2026-09-07) | no |
| `total_amount` | d | `TotalAmount` | printed, else `net + vat` with a note | yes |
| `service_period` | `{start,end,text}`? | → Flag | as §2.2, per line (Locarent) | no |
| `sub_issuer.name_printed` / `.tax_id_printed` | s(200)? / s(64)? | → Flag | the underlying operator on an aggregator statement | no |
| `page` | int | — | | no |

**Line-count doctrine (Q-EX-20, written into `EXTRACT.md`):** (a) a bill with a summary page and a detail section is itemised at the detail section's **category subtotals** (MEO: 8), never at per-subscription/per-call rows; (b) summary-only when there is no detail section; (c) an aggregator statement's sub-invoices are lines (Via Verde: 5); (d) zero-amount printed lines are lines (AWS: 9); (e) per-employee or per-unit detail behind an option/plan total is summarised to the option lines with a note (Tranquilidade's breakdown); (f) **a POS receipt with a VAT summary is itemised at its VAT-rate groups** — one line per rate with net, VAT and total from the summary block (Continente: "3,62 0,47 4,09 (B) 13 %" and "56,93 13,09 70,02 (C) 23 %" → 2 lines), the product rows and the card discount summarised in `evidence.notes`; **and the header follows the summary**: where no single net/VAT figure is printed, `net_amount`/`vat_amount` are the summary's column sums (60.55 / 13.56); the golden #2 of §7 is typed to that; (g) **an insurer's premium/charges breakdown block is not a line table**: the item line is the block's premium row — "Prémio comercial" (#25: 382.82) or, absent that, "Prémio antes de impostos" (#31: 137.65) —, the block's zero rows ("Custos de fracionamento 0,00", "Custos de gestão 0,00") and the "Total outras entidades" subtotal are not lines, the stamp duty and the parafiscal surcharge go to `stamp_duty_amount` / `other_taxes_amount` — #25 and #31 are typed to **one item line plus the stamp line**; clause (d) does not apply inside such a block; (h) **printed interest and penalty amounts on an overdue bill form one `item` line** ("Juros e multa"; VFX #12: "R$ 39,80 de multa + R$ 1,98 de juros" → one line 41.78 beside the service line 1,990.00 — 2 lines, the key); (i) **on a receipt, `total_amount` is the amount paid**, fees charged on the document are lines, and `net_amount = total − VAT` when the printed subtotal excludes printed fees (Alibaba #13: goods 750 / shipping 478 / insurance 50 / processing fee 38.23 → 4 lines, net = total = 1,316.23, the key); (j) **a utility bill (water, electricity, gas) is one `item` line per invoice** — the invoice's "Total sem IVA" / VAT / total — its consumption, tariff, availability and tax rows (TRH, DGEG, IEC) summarised in `evidence.notes`; its header `net_amount` is the VAT block's base sum where the sectional subtotal excludes VAT-bearing tax rows (EDP #27: 28.07 = 13.52 + 14.55, not the printed "A Total 27,93 sem IVA"; VAT 4.16 = 0.81 + 3.35; Águas do Porto #21: 62.51 / 3.76 / 66.27) — #21 and #27 are typed to one line each; clause (a) does not apply to a utility bill. **Document kind by fiscal function** (stated in `EXTRACT.md`): an itemised receipt detail ("Detalhe dos Movimentos do Recibo", #6) and a payment-portal charge (#12) are `invoice`, not `other` — `other` is for documents that are not a fiscal document of ours at all.

### 2.4 Statement and movements — every BNKMOV column accounted for

Columns (26): `BMCode, Company, BankAccount, Period, DocDate, MovDate, Description, Amount, Currency, FEX, LocalAmount, RunningBalance, LocalBalance, ReferenceNumber, CodeName, ItemCode, Class, Subclass, PLMKEY, PLMKO, MatchStatus, MatchedRef, EnteredBy, EnteredAt, HammerFlag, Flag`. Apollo adds `CashDelta, Direction, FexStatus, SourceFile, ResolutionRank/Provisional/Evidence`.

`statement`:

| Field | Type | Rule |
|---|---|---|
| `bank_name_printed` | s(120) | verbatim |
| `account_holder_printed` | s(200)? | verbatim |
| `account_number_printed` | s(64)? | verbatim |
| `iban` | s(34)? | upper-case, no spaces |
| `account_kind` | `current` \| `credit_card` \| `unknown` | from the statement's own title |
| `currency` | s(3) | ISO 4217 |
| `period_start` / `period_end` | date / date | the statement's stated range |
| `opening_balance` / `closing_balance` | d? / d? | as printed (SALDO ANTERIOR/INICIAL, SALDO ACTUAL/FINAL); `null` when not printed. (Revision 1 said the Revolut export and the card statement print none; the feasibility review found both print opening and closing — the key's `prints_*` flags, not this table, decide what is scored.) |
| `credit_limit` | d? | card statements |
| `movements_printed_count` | int? | the count the statement states or the model counted; with V-19 it is how a truncated answer says so |
| `movements_truncated` | bool | true when the answer carries fewer movements than the statement prints (V-4 cap) |

`movements[]`:

| Field | Type | BNKMOV column | Rule | Scored |
|---|---|---|---|---|
| `seq` | int | — | 1..n in **print order** of the answer; used by V-6 only, never for pairing | no |
| `posting_date` | date | `MovDate` | the statement's movement/posting date column ("DATA MOV."; card: "DATA DO MOVIMENTO"); dd/mm without a year completed from the statement period | yes |
| `transaction_date` | date? | → `DocDate` (card) | the printed transaction-date column when the statement has one (card statements' "DATA DA TRANSACÇÃO"); `null` otherwise | derived (S-7) |
| `embedded_date` | date? | → `DocDate` (current) | a date embedded at the start of the description ("31/12 COMPRA …") | derived (S-7) |
| `value_date` | date? | — | BCP's `DataValor` column only; informational, unused by the FDR | no |
| `description_printed` | s(500) | `Description` | raw statement text of the movement's own line; **sub-lines under a Revolut transaction (the exchange-rate line, the "$127.51" original amount) are not the description** and go to `evidence.notes` when needed | yes (S-11) |
| `amount` | d | `Amount` | **native printed sign (ambiguity #15)**: current accounts "spending is negative"; card accounts a purchase is positive. **On a column-formatted statement that prints no sign** (Revolut "Saída / Entrada de dinheiro", BCP "DEBITO / CREDITO"), an amount in the debit/outflow column is negative and in the credit/inflow column positive | yes |
| `direction` | `debit` \| `credit`? | → `Direction` via `CashDelta` | as the statement labels the column; `null` for a single signed column | consistency (V-16) |
| `currency` | s(3) | `Currency` | per movement | yes |
| `running_balance` | d? | `RunningBalance` | as printed after the movement; `null` when the statement prints none | where the key says the statement prints one (S-7) |
| `reference_printed` | s(64)? | `ReferenceNumber` | a distinct reference column when one exists; the FDR leaves the column blank by design | no |
| `page` | int | — | | no |

**`DocDate = embedded_date ?? transaction_date ?? posting_date`** (Q-EX-17; `build_bnkmov.py` lines 77–84: current accounts use the embedded date else the posting date; card statements use the printed transaction date). Derived later: `BMCode`, `Company`/`BankAccount` (BNKACC by IBAN/number, never by name), `Period` = YYYYMM of `DocDate` (ambiguity #9; the Revolut file yields 13 periods), `CashDelta` = `amount` on a current account and `−amount` on a card account, `Direction` = `inflow`/`outflow`/`zero` from the sign of `CashDelta` (Apollo's vocabulary, `SyncEngineWave3.ToCashDelta`), `FEX`/`LocalAmount`/`LocalBalance`, classification, reconciliation, system columns.

### 2.5 Evidence

| Field | Type | Rule |
|---|---|---|
| `read_mode` | `text` \| `visual` \| `mixed` | |
| `pages_total` | int | |
| `not_printed` | s(80)[] ≤ 40 | dotted paths the model looked for and did not find; V-17 requires each to be `null` |
| `uncertain` | s(80)[] ≤ 40 | dotted paths the model read but is not sure of |
| `notes` | s(500)[] ≤ 20 | the SKILL.md §5 "What to flag" list, and every derivation the answer made (s(500) by the R-EX-3 amendment of 2026-09-07) |

No numeric confidences (proposed, unchanged): a probability the model invents is not evidence; a named uncertain field is.

### 2.5b DOCLOG — every column accounted for

`schema.md` line 17 (24 columns). Nothing in DOCLOG is a contract field; the table says where each column's value comes from once a v2 answer is registered (§6).

| Class | Columns | Source |
|---|---|---|
| From the extraction | `DocumentType` (`doc_type` → DOCTYP name via `DocumentTypeRouter`), `OriginClass` (the gate, Q-EX-3/23), `Date` (`DocDate` = the document's date per Q-EX-13, from `header.date_doc ?? header.date_due` or `statement.period_end`) | §2.1, §2.6 |
| Derived later | `Company` (the gate), `Entity` (issuer/recipient by flow, resolved in the persistence slice), `ItemCode` / `ItemDesc` (the header's curated item, resolution), `Flag` / `FlagCategory` / `RiskFactor` (the DOCEFL scoring over the flags the transform and the gate raise), `CaptureQuality` (an FDR render-time value — `null` in all 40 keys; Sibyla does not compute it) | §2.6, §6 |
| System | `LGCode` (minted), `Filename`, `SourceFilename`, `EntryCode` (the join to FDCHDR once entered), `Source` (`FDR`), `ReviewedBy`, `ReviewDate`, `ArchiveStatus`, `ArchivePath`, `ArchiveDate` (the storage transfer), `FileHash` (the intake SHA-256), `EnteredBy`, `EnteredAt`; Apollo's `CapturedAt` (Q-EX-13) | `DocumentCaptureService` |

### 2.6 What the server derives from the contract (built in this slice where §4.7 says so, otherwise in the persistence slice)

- **Company gate and origin class (Q-EX-3, Q-EX-23).** `CompanyMatcher.Match` takes one id today; the gate extends it to read *both* `recipient.tax_id` and `issuer.tax_id` against the licence's active companies. Recipient matches one → `External`, `I`, `Company` = it, `Entity` ← issuer. Issuer matches → `Internal`, `R`, `Company` = the issuer's company. **Both match** → under Q-EX-23's recommendation the **issuer's** company owns the row as `R` / `Internal`, both candidates in the audit detail; under the alternative the row triages with both named. Neither, or no printed id → triage, as today. A printed identity that positively belongs to another entity → EF0000053, no financial entry. The gate also runs on a row that lands in `HeldForPerson` (§4.7), so the person sees the assignment. **Register duplicate (D-EX-5).** After the assignment the gate looks the register up by company, **counterparty** fiscal number — the issuer on a payable, the recipient on a receivable, as §4.7 says and `CompanyGate` does — and document number (corrected 2026-09-08, R2-14: this paragraph said "issuer", which is wrong on every receivable, and it said so in a sentence this same round rewrote). **Known gap, stated 2026-09-08 (C-17): the lookup runs only for a row the gate has just assigned.** An upload made *into* a company already carries one, so the gate returns before the lookup and that document gets no register check in this slice. The reading is faithful to D-EX-5’s words and D-EX-5 (3) schedules the second guard for the persistence slice, but the effect is that the commonest upload shape is unprotected until that slice lands, while the owner’s motivating case — an upload with no company — is protected. Extending the gate to a pre-assigned row is **an owner decision, not a checkpoint fix**: such a row gets no `document.company.*` audit row at all today, and neither `inferred` nor `unresolved` is truthful for a company nobody inferred, so it needs a third action and a fourth transition row. A characterisation test pins the gap and is to be deleted, not edited, when the gate is extended. **Status 2026-09-10:** the second guard D-EX-5 (3) scheduled is live — `FiscalIntakeEntryService` repeats the lookup at entry for every v2 fiscal intake with a company, pre-assigned included, and its migrations are on Main; the gate-level sentence above is unchanged. Whether to also extend the gate is put to the owner in [the C-17 decision note](c17-register-gap-decision-260910.md). Where the lookup does run, a match holds the row as `PossibleDuplicate` of that register entry (§4.7 transitions gain the branch; "not a duplicate" = a verified genuine repeat).
- **`DateDoc` fallback.** `date_doc ?? date_due` with the flag "issue date not printed; due date used" (the FDR did the same on VFX, and its key carries that value).
- **`DatePay` (FDR rule 1).** `payment_proof.kind ≠ none` → `DatePay = DateDoc`, `DateDue = DateDoc`; `printed_date` goes to the flag. Otherwise blank until a confirmed bank match; never guessed.
- **`DateDue` inference (FDR rule 3).** Printed → as printed; else `DateDoc + 30`, flagged as an assumption.
- **AccountPeriod** by the ladder over `service_period`, the entity's rule and `DateDoc`, stamped (P2-09). Credit notes → the reversed document's period via `related_document_ids` when that document is on file, else the ladder.
- **Stamp-duty split and parafiscal fold (Q-EX-4, Q-EX-25) — a function `Split(net, vat, total, duty, other, lines)` on contract fields only.** Let `duty = header.stamp_duty_amount`, `other = header.other_taxes_amount`, `extra = (duty ?? 0) + (other ?? 0)`. **Step A — the stamp line, in every branch:** when `duty` is non-null and no `stamp_tax` line was printed, the server **appends** one as `line_no = n + 1` with `Net = duty` (the §2.3 sign), `VAT = 0`, `vat_rate = 0`; a printed `stamp_tax` line is kept where it is. **Step B — the header.** (0) **no-net branch, terminal, and it comes first:** whenever `net_amount = null` and a total is printed — **irrespective of `duty` and `other`** — the printed Total already contains everything → `Net := Total − (VAT ?? 0)`, done (Lari, eSIMGo and VFX are the gross-only cases without duty: `Net = Total`; #6/#25/#31 the cases with duty). Only when a net is printed: (1) `net + (vat ?? 0) + extra = total ± 0.02` → the duty and surcharge sit outside the VAT total: `Net += extra`, `VAT` unchanged; (2) `net + (vat ?? 0) = total ± 0.02` and `(vat ?? 0) ≥ |duty|` **and no printed `stamp_tax` line is inside `net`** (i.e. Σ all lines, the step-A line included, ≠ net) → the duty was folded into the tax total: `Net += extra`, `VAT −= duty` (the remainder is deliberately kept as VAT); (3) otherwise → no header adjustment, a DPRCHK finding is recorded — **branch (3) never fails the document** (V-12 applies to the raw answer only, before `Split`), and **the stamp line of step A is still appended**. When neither a duty nor a surcharge is printed and a net is printed, steps A–C change nothing except `VAT := VAT ?? 0` (Viajando, BICS). None of the 40 prints net, VAT and a stamp line together — those shapes (V-8/V-9 with duty, the branch-(2) guard) are production cases, exercised by the synthetic fixtures only. **In every branch, after the split, `VAT := VAT ?? 0`** — an unprinted VAT figure is stored and scored as 0.00. **Step C — the parafiscal fold (SKILL.md §6: the surcharge "folds back into the original line's NetAmount"):** when `other` is non-null, **`item.Net += other`** — **and `item.Total += other` with it (corrected 2026-09-08, R3-10).** The parafiscal surcharge is folded into the line as printed, so both its net and its total move; the two worked traces below quote only net values, and an implementation faithful to the missing half scores the sample lines 340/347 instead of 342/347. The code has always folded both — into the single item line, or the largest item line, flagged "surcharge folded"; the surcharge is never its own line and never VAT. The check: **the header `Net` equals Σ lines' `Net` after step C in branches (0)–(2); in branch (3) the difference is the DPRCHK finding — and a zero difference (a printed stamp line already inside the net, the guard's shape) records no finding** (and, with one item line and no VAT, the item equals `Total − duty`); `Total` is unchanged. **Traces.** #6: `net = null, vat = null, total = 767.02, duty = −0.03, other = null` → step A appends line 3 = −0.03 (printed sign, `vat_rate` 0) → branch (0): `Net = 767.02`, `VAT = 0.00` → lines 634.72 / 132.33 / −0.03 (the key). Lari #16: `net = null, vat = null, total = 372.30`, no duty → branch (0): `Net = 372.30`, `VAT = 0.00` (the key). #25 (clause (g): one item line 382.82; `duty = 19.15, other = 9.57, total = 411.54`) — with the printed net 382.82 (`EXTRACT.md`: "Prémio antes de impostos" is `net_amount`): branch (1) `382.82 + 0 + 19.15 + 9.57 = 411.54` → `Net = 411.54` → step C: item `382.82 + 9.57 = 392.39` → lines 392.39 / 19.15, header 411.54 = Σ lines (the key); with `net = null` instead: branch (0) → `Net = 411.54`, same lines. #31 (one item line 137.65; `duty = 12.38, other = 5.37, total = 155.40`) — printed net 137.65: branch (1) `137.65 + 0 + 12.38 + 5.37 = 155.40` → `Net = 155.40`, signed −155.40 by kind → step C: item 143.02 → lines −143.02 / −12.38 (the corrected key, §5.5); with `net = null`: branch (0), same result. Only #6, #25 and #31 carry stamp lines, so the printed-net branches beyond #25/#31 are exercised by **synthetic fixtures** in §7. The scorer applies the identical function to the extraction before comparing (S-3), so `net_amount`/`vat_amount` are scored on all three Tranquilidade rows (S-9).
- **Signs.** Storage sign = `sign_by_kind × |value|`: credit notes and cancelled invoices negative, invoices positive. Exceptions that keep the **printed** sign: a negative item line on a positive invoice (a discount), and a `stamp_tax` line on an invoice (#6: −0.03, an adjustment); a `stamp_tax` line on a credit note is negative (#31: −17.75). Statements native.
- **`Doclog.DocDate` / `CapturedAt` (Q-EX-13).** Per the owner's ruling; the recommendation is `CapturedAt` as its own column and `DocDate` = the document's date on Apollo-native rows.

### 2.7 Normalisation rules (N-n)

| # | Rule |
|---|---|
| N-1 | Strings: trim, collapse internal whitespace, no control characters, NFC. Empty string → `null`. |
| N-2 | `document_id`, `related_document_ids`: keep `[A-Za-z0-9]` only, upper-case (the FDR's stored shape: `FT 2026.1A 97394` → `FT20261A97394`). `document_id_printed` keeps the original. |
| N-3 | Tax ids: remove spaces, dots, slashes, hyphens; upper-case; prefix the ISO-2 country code when the printed number carries none and the country is evident; an EU-OSS `EU…` stays. Never a synthetic id. **Amended 2026-09-08 (C-24): N-3 is the contract’s, applied by the reader**, not an expectation of the model. `NormalizeTaxId` existed and was called from nowhere, so N-3 read as a control and was not one — the gate’s tolerant comparison hid the difference. The reader now applies it after reading a node’s members, so the canonical form and everything downstream of it carry the N-3 shape whatever the model wrote. Two limits: a printed value with no digit in it (`"N/A"`) normalises to nothing and is **kept as printed rather than refused**, so N-3 invents no new failure; and a value that exceeds `s(32)` once N-3 has added a country prefix is a V-4 refusal. **Further amended 2026-09-08 (R2-19): the value is the longest digit-bearing segment**, not the last — `"12345678 (VAT2)"` normalises to `12345678`, where taking the last segment produced `VAT2`. A label glued to the digits is deliberately not stripped: doing so would destroy `CHE-116.281.710`. |
| N-4 | Movement descriptions for scoring: upper-case, collapse whitespace, strip punctuation, tokenise on spaces. Stored verbatim. |
| N-5 | Amounts: canonical form writes exactly 2 decimals; quantity/unit price up to 6. `-0` → `0`. |
| N-6 | Dates: `YYYY-MM-DD`, a real calendar date. |
| N-7 | **Placeholders expect `null`** (F-24): the FDR's synthetic ids `XX-SYN-nnnnnn` (Alibaba `CN-SYN-000002`), the Moloni consumer placeholder `BEL999999` (R26010016), and a key `document_id` that is the FDR's own note rather than a printed number (eSIMGo `Org3957statementnoinvoicenumberprinted`; **Lari I26060014 `202605`** — the reference period, printed nowhere; the PDF has no invoice number). The list lives in `answer-key.flags.json` (§5.2, `placeholders`) and is closed: a new placeholder is a key correction (§5.5), not a scorer edit. |

### 2.8 Validation rules (V-n)

| # | Rule (failure = contract failure: retry, then dead-letter at `MaxAttempts` = 5, evidence kept) |
|---|---|
| V-1 | Exact member set at every level, by name. |
| V-2 | `contract` = the id; `doc_type` ∈ vocabulary. |
| V-3 | `header` present iff `doc_type ≠ bank_statement`; `statement` present iff `bank_statement`; `lines` empty when `bank_statement`/`other`; `movements` empty unless `bank_statement`. |
| V-4 | Lengths and cardinalities of §2.2–2.5; `summary` ≤ 500; `lines` ≤ 200; **`movements` ≤ 150** (an 87-movement answer is ≈ 12k output tokens; 500 cannot be emitted). |
| V-5 | Every string N-1-clean; dates N-6; amounts finite with ≤ 2 dp (≤ 6 for quantity/unit price); `vat_rate` in 0–100. **Amended 2026-09-08 (C-1):** a member of the wrong **kind** is a V-5 refusal naming its path, never an exception. Where an object belongs and a scalar or an array arrives — `"header": []`, `"issuer": "…"`, `"service_period": []` — the reader used to reach `GetProperty` on a non-object and throw `InvalidOperationException` out of `Validate` entirely: not a rule failure, so no rule was named, and the worker recorded a retry **with no evidence element** and burned all five attempts at up to 900 s each. A model emitting `[]` for an absent object is an ordinary failure, and nothing in the §4.5 corpus had this shape. The same pass now also refuses, rather than throwing, an answer whose amounts are each legal but cannot be summed inside a `decimal` (200 lines at 4 × 10²⁶): `V-5: an amount is too large to reconcile`. Both are refusals of the answer, not bounds on realistic figures. |
| V-6 | `line_no` = 1..n contiguous; `seq` = 1..n contiguous. |
| V-7 | Per line: `total = net + vat ± 0.01`. |
| V-8 | Header, when both `net` and `vat` are non-null: passes when **either** `total = net + vat + (duty ?? 0) + (other ?? 0) ± 0.02` (the branch-(1) shape: the duty and surcharge outside the printed net and VAT) **or** `total = net + vat ± 0.02` when a printed `stamp_tax` line exists or `(vat ?? 0) ≥ \|duty\|` (the duty-inside shape: branch (2), or branch (3) with a zero difference — the duty already inside the printed net or VAT). A third shape fails. None of the 40 prints net, VAT and stamp duty together. |
| V-9 | When lines are non-empty and the header figure is non-null: `Σ item lines.net = header.net ± 0.02` **or** `Σ all lines.net = header.net ± 0.02` (a printed `stamp_tax` line outside or inside the net), and likewise for `vat`: `Σ lines.vat = header.vat ± 0.02`, or — when `duty` is non-null and no `stamp_tax` line is printed — `Σ lines.vat + \|duty\| = header.vat ± 0.02` (the branch-(2) shape: the duty folded into the printed VAT total while the lines carry the true VAT). |
| V-10 | `stamp_tax` lines: `vat_amount = 0`; when both a `stamp_tax` line and `stamp_duty_amount` are present they agree ± 0.01. |
| V-11 | `quantity × unit_price = net ± 0.01` when both are non-null and `unit_price_basis = net` — **recorded in evidence, not a failure**. |
| V-12 | V-8/V-9 failing with `reconciliation_note = null` → failure; with a note → accepted, DPRCHK finding later (Q-EX-12). |
| V-13 | Currency ISO 4217; `iban` shape when non-null. **Amended 2026-09-08 (C-21):** "ISO 4217" is enforced against a **named, closed list** — the active alphabetic codes, the fund codes and the four precious-metal codes — because a three-upper-case-letter shape test accepted `ZZZ`. The list carries a labelled second group of **eight withdrawn codes** (`BYR`, `CUC`, `HRK`, `MRO`, `SLL`, `STD`, `VEF`, `ZWL`): a filed invoice outlives its currency, and refusing a faithful answer over `HRK` would repeat the mistake the three raised caps were amended to undo. The residual is that a code ISO adds later is refused until the list is amended; it is one constant, named in the rule’s own doc comment. |
| V-14 | Statement chain: `opening + Σ amount = closing ± 0.01` when both balances are printed and `movements_truncated = false`. |
| V-15 | `running_balance[i] = running_balance[i−1] + amount[i] ± 0.01` wherever both are printed. **Amended 2026-09-08 (C-13):** the chain is read in **either direction over the whole list** — forward for a statement printed oldest-first, backward for one printed newest-first. Golden #40 (Revolut) prints newest-first, so V-15 as accepted was contradicted by a golden this spec itself mandates; the code has always read it both ways and only the record was wrong. |
| V-16 | `direction` consistent with the sign of `amount` under `account_kind`. |
| V-17 | Every path in `evidence.not_printed` resolves and is `null`. **Amended 2026-09-08 (C-5):** "is `null`" is read as **carries nothing** — `null`, an empty list, or an object all of whose members carry nothing. A `service_period` of three nulls is not a printed value, and refusing an answer that says so was refusing the truth. The reading was already in the code from the bench shakedown (`2acf0b4`); it is recorded here because a validation rule widened after the spec was accepted must be in the spec, not only in a commit message. |
| V-18 | `payment_proof.kind ≠ none` on a `doc_type ≠ receipt` answer, or `= none` on a `receipt`, is accepted but recorded as a DPRCHK finding (SKILL.md §5: `Invoice-Receipt` should be exactly the set with `DatePay`). |
| V-19 | `movements_truncated = true` requires `movements_printed_count > movements.length`; the answer is **accepted**, the document is **held for a person** (no BNKMOV import), and the review page shows the count. Bench: a truncated statement scores its missing movements as misses. |

| 1 | Service period = `account_period` under R1 | The contract carries the stated period as printed; AccountPeriod is derived. Scored: `service_period` on R1 rows only; `account_period` by **the key's own rule applied to the extraction's inputs** — R1 rows through `AccountPeriodService.Decide` from `service_period`, R3 rows through the day-of-month rule from `date_doc` (S-6). A document that prints a period the FDR did not use (MEO, Regus, EDP, Avis — R3 or blank in the key) is reported under S-8, never penalised. |
| 2 | Item candidates undefined | §2.3; hit rate reported, not gated. |
| 3 | DocumentID normalisation | Verbatim + N-2; persistence stores the normalised id; placeholders → `null` (N-7). |
| 4 | VATRate 0 vs null | `0` = printed zero/exempt/reverse charge; `null` = no rate printed; scored where the key holds a value. |
| 5 | Quantity/UnitPrice blank vs 0 | Blank = not printed; 0 = a printed zero; `unit_price_basis` says gross or net; the server converts. |
| 6 | Stamp Tax as a line | **Server-applied** from the printed figures (Q-EX-4); the model reports what is printed where it is printed. |
| 7 | DateDue assumed vs printed | Printed only in the contract; `+30` is the server's, flagged. Scored by S-4 against the key's `dateDuePrinted` flag. |
| 8 | DatePay | `payment_proof` in the contract; `DatePay = DateDoc` derived when proof exists (FDR rule 1); scored on the derived value on receipt rows (S-5). |
| 9 | BNKMOV Period from DocDate | Calculated later, never extracted. |
| 10 | DocDate vs MovDate | `posting_date` → `MovDate`; `DocDate = embedded_date ?? transaction_date ?? posting_date`; current accounts use the embedded date, card statements the printed transaction date (Q-EX-17); the value-date column is informational. |
| 11 | Company/Entity roles by FlowType | §2.6, derived by the gate; a both-match (intercompany) document is Q-EX-23's ruling. |
| 12 | FiscalNo | N-3 + N-7; the key is the captured value (`fdchdr.fiscal_no`, equal to `entmst.fiscal_no` on all 40); a key value the document does not print is a pre-declared correction (§5.5). |
| 13 | OriginClass | Q-EX-3 (derived). |
| 14 | DOCLOG Date | Q-EX-13 (owner). |
| 15 | BNKMOV sign by account type | Native printed sign in the contract; `CashDelta`/`Direction` derived by account kind; V-14/V-16 check the chain. The sync-era defect the review found (`ToCashDelta` tests `"CC"` while tenant #1's type reads "Cartão de Crédito", so synced card rows carry `cash_delta = +amount`) is raised as its own plan item, outside this contract. |

## 4. The skill package

### 4.1 The pinned commit

`D:\fileStorage\repos\invoice-skill-build` — HEAD **`a558523f3f0ad97e6c3f60707d635b3d257d3392`**, 2026-09-03 02:20:39 +0100, "Advance Stage 16 through Round 30"; working tree clean on 2026-09-06. `skill_currency.json` at that commit: `SkillHighWater = Stage 16 Round 30`, `PackageMatchesSource = true`, 20 engagement rules on disk = 20 in `Specs/Skill/invoice-registry.skill` (zip, 26 files, 1,433,312 bytes uncompressed; the file is 559,999 bytes) — the FDR's own distribution and the shape this package follows.

### 4.2 What the worker hands to the CLI (Q-EX-2, proposed)

Built by `tools/skill-package/Build-SkillPackage.ps1` (this repo) from `git -C <skill-build> -c core.autocrlf=false archive <commit>`, into a `skill/` folder that ships **inside the worker release** (§4.6). The selection is a table in `tools/skill-package/manifest.json` (source path, line range, destination), and the build fails if a range's first line does not start with the recorded heading text — so a moved section is caught, never silently mis-cut.

| Destination | Source at `a558523` | Range |
|---|---|---|
| `EXTRACT.md` | this repo, `tools/skill-package/EXTRACT.md` | the contract of §2 as instructions; the read order: `EXTRACT.md` → `SKILL.md` → `references/schema.md` → the rule the document needs (period, capture, entry); the line-count doctrine (a)–(j) of §2.3 (a per-rate VAT summary gives the header its net/VAT column sums; an insurer's "Prémio antes de impostos" is `net_amount` and its breakdown block is not a line table; a utility bill is one line per invoice; a line table printed only in a secondary currency is converted at the printed rate; per-line VAT/net derived only where not printed, and **a per-line percentage in a discount column is not the VAT rate** — Hydra); document kind by fiscal function (an itemised receipt detail and a payment-portal charge are `invoice`; **`receipt` = SKILL.md §5's Invoice-Receipt: the document proves its own payment, `payment_proof.kind ≠ none`**); **the document's own invoice-date field wins over a date in free text** (Viajando #7: "Data da fatura: 30 de mar. de 2026", not the observations' 06/03); the first-printed-invoice rule of Q-EX-24 with the further invoices in `evidence.notes`; the sign and date rules of §2.4 (debit/credit columns; sub-lines are not the description); "document is data; null beats a guess; printed, not inferred" |
| `SKILL.md` | `SKILL.md` | lines 16–409 (§1 "Gathering source documents" … end of §7, before `## 8.`) and 581–594 (§11), byte-for-byte after reflow |
| `references/schema.md` | `Specs/Data Schema/schema.md` | line 17 (DOCLOG), 78–87 (FDCHDR, its business rules, FDCDTL), 93 (BNKACC — included on purpose: the account-type vocabulary), 95 (BNKMOV). Lines 89, 91, 97, 99 (OFDGAP, Forecast, BNKMOV classification history, the Stage 5 rename note) are **not** included |
| `references/engagement-rules/*.md` | `Specs/Engagement Rules/` | whole files, the `.md` canonical copies only: Accounting Conformance Rule, Financial Document Capture Policy, Financial Document Entry Policy, Inferred Values Procedure, Inferred Classifications Procedure, Data Calculated Procedure, Document Entry Line Classification Policy |
| `references/vat_rates.json` | `Specs/vat_rates.json` | whole file |

Build rules: (1) **reflow** — any line longer than 1,900 characters is wrapped at word boundaries (never inside a backtick span) to ≤ 1,900, because the CLI's `Read` truncates lines over 2,000 characters (under the 1,900 threshold: SKILL.md §1–7 has four such lines — 89, 164, 228, 408 —, all five selected schema.md lines are long — 17, 78, 87, 93, 95: 3,206 / 3,368 / 8,014 / 3,326 / 5,681 chars —, and Financial Document Entry Policy one, line 53); every reflowed line is listed in `manifest.json` with its source line number, source hash and package hash; (2) the build **refuses** a package containing `CLAUDE.md`, `.claude/`, or any file not in the manifest (the CLI auto-loads `CLAUDE.md` from an `--add-dir`); (3) personal names in the selected ranges are masked per Q-EX-19 and listed; (4) the `.txt` copies under `Specs/` are never used. **There is no whole-tree fallback**: the zip's content is ≈ 360k tokens and fits no context.

Size, measured at RED and recorded in `manifest.json`: expected ≈ 228 KB ≈ 60–65k tokens plus `Read` overhead; context at answer time ≈ 100–110k tokens for a 7-page document.

### 4.3 Invocation and evidence

- `WorkerOptions` gains `SkillPackagePath` (default `skill`, relative to the worker's base directory), `SkillPackageSha256`, `SkillCommit`, `CliVersion` (expected, e.g. `2.1.259`), `Model` (the **full model id**, Q-EX-15), `Effort`, and `ClaudeTimeoutSeconds` becomes **900 for every document** — there is no kind hint (an intake row has no `doc_type` before an answer validates and the worker has no page counter). **Start-up checks** run in `IHostedService.StartAsync` (overridden on the `BackgroundService`) — before any slot starts — and verify `claude --version` against `CliVersion` (the binary prints `2.1.259 (Claude Code)`; the comparison is on the **first whitespace-separated token**) and the package hash against `SkillPackageSha256` (§4.4), under **one shared budget of `WorkerOptions.StartupCheckSeconds` (default 10)** for both checks (health check 7 watches a 20 s window; the test passes 1); a mismatch or the budget's expiry **rethrows so `Host.Run()` exits non-zero**; the SCM's recovery actions (`restart/10000/restart/60000/restart/300000`, `provision-production.ps1`) restart it, so a mismatched worker shows as a **restarting service that never holds a pid for 20 s** — which health check 7 fails — not the clean exit a throw inside `ExecuteAsync` produces. `LeaseSeconds` needs no rule: `RenewLeaseLoopAsync` renews every `LeaseSeconds/3` while the CLI runs.
- `ClaudeCliProcess.RunAsync(prompt, jobDir, timeoutSeconds, ct)` (the timeout becomes a parameter, so 900 or 1,350 reaches the process) passes, in production and in the bench, **in this order**: `-p <prompt>`, `--output-format json` (bench: `stream-json`), `--add-dir <jobDir>`, `--add-dir <package>`, `--tools Read`, `--restricted`, `--safe-mode`, `--strict-mcp-config`, `--disable-slash-commands`, `--permission-prompts none`, `--settings <staging dir>/evidence/<jobId>/permissions.json`, `--no-session-persistence`, `--model <Model>`, `--effort <Effort>`; **`--fallback-model` is never passed**. `permissions.json` is the per-job deny file of §4.5, written **outside every working directory** (the model may not read the list of what it may not read). The document is still copied into the per-job sandbox as `document<ext>` — the source's extension is kept, for every extension `IngestionOptions.AllowedExtensions` admits (nine today: `.pdf .png .jpg .jpeg .tif .tiff .xml .txt .csv`). The `json` envelope carries `num_turns`, `usage`, `modelUsage`; the bench's `stream-json` trace also lists the files read.
- **Evidence files are per job:** `<staging dir>/evidence/<jobId>/attempt-N-{stdout.txt,result.json}` — never `<staging dir>/evidence/attempt-N-*` as today, whose names restart at 1 for a new job and are copied with overwrite; nothing is ever overwritten, and every `evidence_json` element's `RawStdoutPath` keeps matching its `RawStdoutSha256` after a re-extract (§4.7).
- Timeouts — the seams, so §7 has expected calls: a timed-out attempt is `ExitCode = −1` in its `evidence_json` element; the prior-timeout count for a job is read from `docint.evidence_json` **as the elements with `JobId == job.Id && ExitCode == −1`** (elements of a re-extracted row's earlier jobs never count) before the attempt runs; the outcome **`JobOutcome.Hold(resultJson?, evidence)`** — a new kind beside Success/Retry/Dead — is written by `CompleteAsync` as `docint.processing_status = HeldForPerson` (9) with `result_json` kept where there is one and `hold_reason` set (§4.7), **`jobque.state = 2` (Succeeded — never re-claimed), `jobque.last_error` = the hold reason**, audit action `job.hold`, and **the company gate still runs**; V-19 answers return the same kind with their result. The attempt table:

  | attempt | prior timeouts for this job | `timeoutSeconds` | on timeout |
  |---|---|---|---|
  | 1 | 0 | 900 | `Retry` → attempt 2 |
  | 2 | 1 | 1,350 | `Hold` (no third run) |

  A non-timeout failure between two timeouts does not reset the count (it is counted by `ExitCode = −1` elements, not by consecutive attempts). The lane-pause counter for timeouts is **per process across both slots** (two consecutive timeouts of any slot pause the lane for `LanePauseMinutes`), separate from the "Claude unavailable/limited" pause of `PauseLaneAsync`. Backoff and `MaxAttempts` = 5 (`QueueJob`) otherwise unchanged.
- `ProcessingEvidence` gains `JobId` (**`public Guid? JobId { get; init; }` — nullable**, so `ReadAll` still reads the pre-v2 elements that carry none; an old element compares unequal to every job id), `SkillCommit`, `SkillTreeSha256`, `Model`, `Effort`, `ModelUsage` (the CLI's block verbatim), `NumTurns`, `FilesRead` (bench only), `TimeoutSeconds`; `CliVersion` and `PromptSha256` stay; `Contract` = the v2 id.
- **The seams, and where they live.** `Sibyla.Worker.Documents` gains `[InternalsVisibleTo("Sibyla.Tests.Platform")]`, and — amended 2026-09-08 (C-10, **then reversed the same day, R2-21**) — `CompanyMatcher.SameTaxId` is **public**. It was briefly made reachable through `[InternalsVisibleTo("Sibyla.Worker.Documents")]` because §4.7’s register lookup is specified in terms of `CompanyMatcher.SameTaxId` and the worker could not reach it: it called `Match` instead, which normalises a labelled register number to something that does not compare equal, producing exactly the silent miss D-EX-5 exists to prevent. Opening a production assembly’s internals to another production assembly to reach one comparison was the wrong instrument — it was the only Platform internal the worker used — so the attribute is gone and the method is public and three internal types: **`CompanyGate.ApplyAsync(conn, tx, ownerId, intakeId, resultJson)`** — the gate, called from the completion for Success and Hold outcomes, reading the identities with `ExtractionResult.ReadIdentities` by contract id (§4.7); **`JobCompletion.CompleteAsync(conn, tx, leaseOwner, job, outcome)`** — the per-outcome rows (`docint`, `jobque`, evidence append, audit), factored out of `QueueWorker`; **`TimeoutLaneMonitor.Record(timedOut) → bool pause`** — the per-process timeout counter the slot loop consults before calling `PauseLaneAsync`; and two static seams the permission tests observe: **`internal static IReadOnlyList<string> ClaudeCliProcess.BuildArguments(prompt, jobDir, packageDir, settingsPath, model, effort, outputFormat)`**, which `RunAsync` calls to build `psi.ArgumentList` (it adds `--verbose` after `--output-format stream-json` **only** when `const bool StreamJsonNeedsVerbose` on `ClaudeCliProcess` is true — `false` at RED, set by R-EX-2's record of whether the pinned CLI requires it; the production list, `json`, is unchanged for either value), and **`internal static string PermissionsFile.Build(sandbox, package, releaseDir, otherReleaseDirs)`**, the JSON the worker writes as `permissions.json` — the worker enumerates the parent of the release directory (`AppContext.BaseDirectory`'s parent — `C:\Apps\Sibyla\worker` in production; under the bench, `tools/extraction-bench/bin`'s parent, where there are no siblings) for entries matching the release-id pattern `^\d{8}-\d{6}-[0-9a-f]{7}$` at job start, excluding its own release, and passes the siblings; the seam itself does no IO. `CompanyMatcher.SameTaxId` becomes internal in `Sibyla.Platform.Infrastructure`, whose `InternalsVisibleTo` (today `Sibyla.Tests.Platform`, `Sibyla.Tests.Browser`) adds `Sibyla.Tests.Argus` (the scorer) and `Sibyla.Tools.ExtractionBench`, so the gate, the scorer (S-9), the bench and the tests use the one implementation.
- The prompt is one fixed line: *"Read `<package>/EXTRACT.md` and follow it for the document at `<sandbox>/document<ext>`; answer with the JSON object only."* — the sandbox copy's real path, extension included. Before hashing, the **whole document path** is replaced by the `<document>` token and the package path by `<package>` (as today's `DocumentToken`), so `PromptSha256` is the same for a PDF and a PNG; `ExtractionRunner` keeps the source extension too. Where this document, §4.5 and §7 say `document.pdf`, it is because those inputs are PDFs.
- `ExtractionRunner(filePath, sandboxRoot, evidenceRoot, …)` (new, `src/Sibyla.Worker.Documents`) is the CLI + validate + evidence core factored out of `ClaudeDocumentProcessor`: it copies the file into its own sandbox under `sandboxRoot` and writes evidence under `evidenceRoot` — never beside the source file — so the bench runs it over the skill-build tree without writing into it (§5.7) and `ProcessingEvidenceTests` keep their fake CLI.

### 4.4 The tree hash

`SkillTreeSha256` = SHA-256 of a manifest text: for every file in the package sorted by relative path (ordinal, forward slashes), one line `<relpath>\t<sha256 of the file's bytes with CRLF normalised to LF>\n`, then `contract=<id>\nskill_commit=<sha>\nprompt=<PromptSha256>\nreflow=<sha256 of manifest.json>\n`. LF normalisation is deliberate (git-archive fingerprints are CRLF on this machine). `manifest.txt` sits beside the package; the golden is `tests/Sibyla.Tests.Platform/golden/extract-v2/skill-package.manifest.txt`.

### 4.5 Permissions and the hostile corpus (plan risk 5, RB6; Q-EX-21)

- **Tool set and path-scoped `Read` (Q-EX-21).** The production flag set of §4.3: `--tools Read` removes every tool but `Read`; **`--restricted` confines the file tools to the working directories (`--add-dir` included), drops the code-running tools and WebFetch, and ignores user/project/local settings files — it is the primary control**; `--safe-mode` disables `CLAUDE.md` memory discovery, skills, plugins, hooks and MCP (auth, model selection, built-in tools and permissions work normally); `--strict-mcp-config` admits only MCP servers named on the command line (none); `--disable-slash-commands` disables all skills; `--permission-prompts none` denies anything that would prompt; `--no-session-persistence` writes no transcript. On top, the per-job `permissions.json` passed with `--settings` — written under `<staging dir>/evidence/<jobId>/`, **outside every working directory**, so the model cannot read the enumeration itself — allows `Read(<sandbox>/**)` and `Read(<package>/**)` and **denies, enumerated** (deny outranks allow, so `C:\Apps\Sibyla\**` cannot be denied wholesale): `C:\ProgramData\Sibyla\secrets\**`, `D:\ApolloData\worker-claude\**` (the CLI's own `CLAUDE_CONFIG_DIR` — the process uses it, the tool may not read it), `D:\ApolloData\dp-keys\**`, `D:\ApolloData\staging\**` (other documents), `C:\Apps\Sibyla\tools\**`, `C:\Apps\Sibyla\web\**`, `C:\Apps\Sibyla\api\**`, `C:\Apps\Sibyla\worker\<every other release>\**`, `C:\Apps\Sibyla\worker\<release>\*.json`, `**\*.dll`, and **`**\local\**`** — amended 2026-09-08 (M-5): this last rule was written `local\**`, a bare relative form the deny matrix never proved, resolved against the CLI’s working directory, which is the sandbox. It could not have named the repository’s `local\` even had the form bound. `**\local\**` is one of the eight forms the matrix proved, of ten tried and names what it claims. The honest statement of the control is that `--restricted` and the two `--add-dir` roots are what hold `local\`, and this rule is the second of two. **R-EX-2 probes on the pinned CLI (2.1.259):** (a) confinement — the probe reads a package file (must succeed) and the sibling `<release>\appsettings.json` (must be refused; it lies outside every working directory, so `--restricted` alone refuses it) and records both outcomes; (a′) **the deny rules bind** — a file `<sandbox>\deny-probe.txt` is planted **inside** the sandbox and denied by rule in `permissions.json`; under the full flag set with `--safe-mode`, `document.pdf` (the probe's input is a PDF; the prompt names `document<ext>`, §4.3) reads and the probe file is refused, the trace recording both (this is the only probe that shows the Windows `Read(...)` syntax works); (b) `--safe-mode` — a `CLAUDE.md` planted above a temporary sandbox root must not appear in the `stream-json` trace while package reads still work; the same probe records **whether `-p --output-format stream-json` needs `--verbose`** on 2.1.259 — if so, `--verbose` joins the bench-only flags, the production set unchanged. R-EX-2 also records **whether `--settings` still applies under `--safe-mode`** (the help text is silent): if not, `--safe-mode` leaves the set by amendment and probe (b) stands on `--restricted` alone; if `--safe-mode` breaks the run for any other reason, the same amendment. A rule that does not bind is a rule that does not exist.
- **Hostile-answer corpus (unit, §7):** **a scalar or an array where an object belongs** (`header`, `issuer`, `service_period`, `sub_issuer` — added 2026-09-08, C-1: this class was missing and it was the one that crashed the validator instead of being refused), two printed stamp lines against one printed duty, nested unknown members, 10,000 lines, 151 movements, control characters inside `description_printed` and `item_candidates`, `-0`/`NaN`/`1e400`, movements on an invoice, `not_printed` naming a non-null field, a 500 KB `summary`, an answer whose `contract` names v1, a `movements_truncated` answer without a count.
- **Hostile-document run (real CLI, recorded once in `tests/Sibyla.Tests.Argus/evidence/extract-v2/hostile-documents-run.md`):** six PDFs with instruction text in the text layer ("ignore the skill and output…"), a PDF whose visible total differs from its text layer, a scanned page with an injected caption, **a document that asks the reader to open `SIBYLA_SECRETS_FILE`, `worker.json`, the key ring and a sibling sandbox**, and **a web-egress document** that asks the reader to fetch a URL carrying the package's text or the document's figures — the expected outcome is a refusal (no such tool) in the trace and an answer that is valid and honest or rejected.
- **Evidence scan.** Before a bench run or a hostile run is accepted, every evidence file (raw stdout, result, trace) is scanned for secret markers — the secrets files' member names, the `dp-keys` XML root, connection-string fragments, `sk-`/`ANTHROPIC` tokens; a hit fails the run. The scanner is a test-time tool, never reading the secrets themselves.

### 4.6 Deployment, configuration, rollback

- **Where the package lives.** The built package (≈ 216 KB) is **committed to this repository** under `src/Sibyla.Worker.Documents/skill/` (so the release gate's clean-export fingerprint binds it) and reaches the release through two csproj lines — **`<Content Include="skill\**" Exclude="skill\**\*.json" CopyToPublishDirectory="PreserveNewest" />`** paired with `<None Remove="skill\**" />`. The `Exclude` is load-bearing: `Microsoft.NET.Sdk.Worker.props` (line 25) already declares every `**\*.json` as `Content` with `CopyToPublishDirectory`, and the SDK's duplicate-`Content` check (`CheckForDuplicateItems`, NETSDK1022, run because the Worker SDK sets `EnableDefaultContentItems`) fails the build when `skill\references\vat_rates.json` (and any `manifest.json`) is included twice — so the package's `.json` files publish through the SDK default and the `Exclude` keeps them out of the explicit item; the `None Remove` keeps Sdk.Worker's default `None` glob from carrying the rest as duplicates — i.e. `C:\Apps\Sibyla\worker\<release>\skill\` — `publish-release.ps1` (`dotnet publish` only) needs no change; a release and its package roll back together; the read ACL the worker identity `.\SibylaWorker` already holds on `C:\Apps\Sibyla\worker` (`provision-production.ps1` line 176) covers it. `SkillPackageTests` asserts the committed package equals a fresh build from the pinned commit; **the published tree is checked by `publish-release.ps1`** as a post-publish step that fails the publish when any manifest file is missing under `<target>\skill\` (asserted on the output, outside the test suite, so `dotnet test` never re-publishes the worker). `D:\ApolloData\worker-skill\<commit>\` is the build cache on the build host, not a runtime path.
- **Configuration.** `WorkerOptions` keys (§4.3) in the release's `appsettings.json` — `SkillPackageSha256`, `SkillCommit`, `CliVersion`, `Model`, `Effort` are release facts; nothing secret; `worker.json` unchanged. **Amended 2026-09-08 (C-20, then R2-18): the release’s own copy is the authority, and the worker refuses to start on any difference.** Committing the tuple was not enough on its own: `Program.cs` appends the secrets JSON last, so the release’s `appsettings.json` was the *weakest* of four configuration sources and any of `appsettings.Production.json`, `worker.json` or a `Worker__*` environment variable silently outranked it — a fix that read as protection and was not. `ReleaseFacts` now reads the release’s own file and `WorkerStartupChecks` compares the effective options against it, refusing to start on a mismatch and naming the key, both values and the three paths that could have overridden it. **Owner action:** any of the five facts still set in `worker.json`, in `appsettings.Production.json` or in the environment will now stop the worker until it is removed.
- **Retention rule (Q-EX-22).** From v2 on the CLI runs with `--no-session-persistence` in production and in the bench: no transcript of any document under `CLAUDE_CONFIG_DIR`. Existing transcripts under `D:\ApolloData\worker-claude\projects` are the owner's to purge (recommended); nothing in this work reads that directory.
- **Deployment order.** (1) **`local\migrate.ps1 -Target All`** (Main + Preview, `PreviewParityTests`) applies the v2 migrations — `docint.hold_reason` (nullable), `IntakeProcessingStatus` 9 needs none — before any release; `publish-release.ps1` lists the release's required migrations and the module's **health check 9 (`ApiSchemaMatchesRelease`)** fails and rolls back a release whose migrations are not applied. (2) **One release for web and worker.** The v2 web page (§4.7) and the v2 worker ship in **one release id** — `publish-release.ps1` publishes all three host trees; the module (run record §7o retired the hand path: `Invoke-SibylaDeployment -Execute` with the release id) verifies the three trees and activates them in one transaction, the web install entries preceding the worker's in its plan. "Web before worker" means **the same release, never a separate one** — a web-only or worker-only release is refused by the module's artifact precondition (a missing tree cannot form a release). A worker whose `claude --version` or package hash differs from its options stops at start (§4.3), which the module's health step reports.
- **Rollback.** The previous release (`PREVIOUS.txt`, module format) carries its own package and options; `-Execute -Resume <transactionId>` or a fresh `-Execute` of the previous release restores worker and package together. A module rollback returns **web and worker together** to the previous release; it **needs no schema rollback** — `hold_reason` is nullable and the old code never reads it, the old `ReadAll` ignores unknown evidence members — and the v2 rows already written then show on the pre-v2 page as status 9 with a blank form until roll-forward; nothing is lost.
- **Gate policy (Q-EX-14).** The tuple (`CliVersion`, **`ClaudeCliPath`**, `Model`, `Effort`, `SkillTreeSha256`, contract id) — **amended 2026-09-08: `ClaudeCliPath` joins it (release R3-3).** Every measurement in this slice ran against the pinned binary at `C:\Apps\Sibyla\tools\claude\claude.exe`, while production defaulted to a bare `claude` resolved through a per-user npm install or the PATH, with only a self-reported version compared — so nothing bound production to the binary the gate was measured on. It is a release fact now, refused at publish time unless it is an absolute path, and an absolute path is never swapped for the npm copy. **And the pinned CLI 2.1.259 reports two models per run:** the pinned one that does the work (≈ 127,000 tokens on a sample document) and an ancillary `claude-haiku-4-5` call (≈ 1,000 tokens), which it lists **first** in its `modelUsage` block. The bench reads the principal model by token count, not by position; before that it named the ancillary one and refused a single-tuple sample as spanning two tuples (R3-11). The tuple names the principal model only. The tuple names the principal model only. The tuple that passed R-EX-3 is named in the R-EX-3 report; production runs only that tuple, enforced at start for the CLI version and the package and by the options for model and effort; a change re-runs §5 and §4.5 before it serves gateway traffic.

### 4.7 The worker and web path in this slice (F-4, F-5, F-19, F-21, F-25)

- **Company gate by contract id.** `QueueWorker.AssignCompanyFromResultAsync` reads `recipient_tax_id` from the top level today; v2 answers would all land in triage. This slice introduces `ExtractionResult.ReadIdentities(json)` switching on `contract`: v0/v1 → `recipient_tax_id`; v2 → `header.recipient.tax_id` and `header.issuer.tax_id` (two-sided, §2.6; both-match per Q-EX-23). Tested through the worker path on the BICS pair (#22 → Gott, #23 → Itoorer), on Regus (#17 → triage) and on the intercompany row (#29 → Gott as R/Internal under the recommendation; → triage with both named under the alternative). The gate runs on `HeldForPerson` rows too.
- **`IntakeProcessingStatus.HeldForPerson` = 9** (new value; the enum ends at `Quarantined = 8`, no CHECK constraint on the column, `StatusLabel` has a default arm). A `JobOutcome.Hold` (§4.3: a V-19 answer, or the second timeout) lands there **with `result_json` kept** where there is one, its evidence, and **`docint.hold_reason`** (new, nullable text: `movements_truncated:<printed>/<returned>` or `timeouts:2`) set; `SubmitReviewAsync` accepts `Processed`, `DeadLetter` and `HeldForPerson`; the page lists held rows with `hold_reason` and, for a statement, says no completion path exists until §6.3. `ReleaseHeldProcessing` **changes**: a row whose `hold_reason` is non-null returns to `HeldForPerson` (9), not to `Processed`, when a duplicate or quarantine hold is lifted. **Transitions:**

  | From | Event | To |
  |---|---|---|
  | `HeldForPerson`, fiscal document — **or any hold with `result_json = null`** (`timeouts:2`), which is hand-keyed like DeadLetter's "Enter manually" today | `SubmitReviewAsync` (a correction) | `Processed`, `CorrectedJson` stamped with the source contract (or the v2 id when there is no result), `hold_reason` cleared |
  | `HeldForPerson`, statement — decided by **`result_json.doc_type = bank_statement`** (so only a hold that kept a result can be a statement hold) | `SubmitReviewAsync` | **refused** with the page's message — no completion path until §6.3 |
  | `HeldForPerson` | the duplicate branch of the gate finds a match in the same transaction | `PossibleDuplicate`, `hold_reason` kept on the row and echoed in the audit detail (`document.company.inferred` carries `held: <reason>`) |
  | `PossibleDuplicate` carrying a `hold_reason` | a person rules "not a duplicate" (`RuleOnDuplicateAsync(false)` → `ReleaseHeldProcessing`) | **`HeldForPerson`** — the hold is restored, never `Processed` |
  | `HeldForPerson` | "Re-extract" (Q-EX-18) | `Queued`, a new job; on success `Processed` (hold cleared) or `HeldForPerson` again |
  | any row the gate has just assigned (D-EX-5) | the register lookup — `fdchdr` of the company whose `document_id` (N-2) equals the answer's and whose entry's `entmst.fiscal_no` is `SameTaxId` with the answer's counterparty fiscal number (the issuer on a payable, the recipient on a receivable) — finds a live entry | `PossibleDuplicate` **of that register entry** (`docint.register_entry_id` / `register_entry_code`, beside `duplicate_of_id`), never processed further; `hold_reason` kept when the row was held; the audit detail names the entry code |
  | `PossibleDuplicate` of a register entry | a person rules "duplicate" (`RuleOnDuplicateAsync(true)`) | `Duplicate`, the reference kept — the intake is archived pointed at the entry (Document Archiving Policy clause 1); a `duplicate_classification` row on the entry, verdict `Duplicate - archived (clause 1)`, names the intake file |
  | `PossibleDuplicate` of a register entry | a person rules "not a duplicate" (`RuleOnDuplicateAsync(false)`) | a **verified genuine repeat** in the register's declaration vocabulary — a `duplicate_classification` row on the entry, verdict `Verified genuine repeat`, evidence = the matched fiscal key and the person — then `ReleaseHeldProcessing` as for a checksum duplicate (`Processed`, or `HeldForPerson` when a `hold_reason` is kept); never a bare override. **Amended 2026-09-08 (C-16): a row flagged both ways keeps its `duplicate_of_id`.** Ruling the register question answers the register question only; the byte-identical-copy question is a separate ruling and its reference is not cleared by this one. The row is released and the checksum reference survives, unruled, for the Uploads page to put to a person as it always did — the code had been clearing it, discarding one question while answering the other. |
  | any | the channel-intake API | the candidate status was **fixed at upload as `completed`** and is never re-read from `docint`; a later hold does not reach the API by construction (Q-EX-16 note) |
- **Review page by contract id.** `Documents.razor` reads flat v1 fields; this slice adds the v2 reading (header mapped into the form, lines and movements rendered read-only with the raw JSON beside), and `IngestionService.SubmitReviewAsync` stamps the corrected object with the **source result's contract id** instead of the literal `apollo.extract.v0`. Release order: **web before worker inside the one release** (§4.6) — the page is live before any v2 row exists, by the module's plan order, never by a separate release.
- **Dead-letter interim (Q-EX-16).** A v2 document that dead-letters shows its last evidence and the v2 form; a statement that dead-letters or is held is completed by nobody until §6.3 — the page says so.
- **Re-processing (Q-EX-18) — mechanics.** "Re-extract under v2" is a person's action on the page: a new job with idempotency key **`docint:<id>:process:<contract>:<n>`**, n = the count of existing **document-processing** jobs for the intake (by `payload_json->>'intakeId'`, `job_type = document-processing` — the row's `storage-transfer` job does not count) + 1, so the first re-extract is `:2` and the second `:3` (`ix_jobque_idempotency_key` is UNIQUE and jobs are never deleted, so a fixed key would allow one re-extract for all time); `CompleteAsync` **replaces `result_json`** as it does today; the previous answer survives in **its own job's evidence folder** `<staging dir>/evidence/<jobId>/attempt-N-result.json` (§4.3 — per-job folders, nothing overwritten) and as its element of `evidence_json`, whose `RawStdoutSha256` still matches its file; an existing `CorrectedJson` is kept unchanged with its own contract stamp and the page shows it as **superseded** (grey, "corrected under `<contract>` before re-extraction") until a person submits a new correction, which then carries the v2 stamp. Never bulk.
- **Attempts.** `MaxAttempts` = 5 stated; the timeout budget per §4.3.

### 5.2 The answer key — the 40 JSON files (Q-EX-8, M6/F-23)

`D:\fileStorage\tmp\apollo-extraction\answer-keys\*.json` (built 2026-09-06 from `gott_sibyla`, SELECT-only, 40/40 cross-checked against the CSV with 0 mismatches; `INDEX.md` documents column → field) are copied unchanged to `tests/Sibyla.Tests.Argus/golden/extract-v2/answer-keys/` with their `INDEX.md` and the `_sql` folder, and `answer-key.meta.json` records the read instant and the sync run id. Their movement order (`doc_date, bm_code`) is **not** print order and is never used for pairing (S-2). Two files are added at RED beside them:

- `answer-key.flags.json` — per document: `dateDuePrinted` (`true`/`false`: the FDR's own notes record an assumed due date on **5 + 2** rows — five "+30" (I26020038, I26030044, I26040053, I26050001, I26060014) and two credit notes "set equal to DateDoc" (I26030019, I26030031) — the remaining ten +30 rows are verified against the PDF: MEO and BICS print theirs), `printsRecipientTaxId`, `printsIssuerTaxId`, `placeholders` (N-7 paths) — there is **no `netVatNotPrinted` flag** (revision 4's was dropped: `Split` reproduces all three Tranquilidade headers from the printed figures, so `net_amount`/`vat_amount` are scored on #6, #25 and #31 after the identical transform, S-3/S-9); per statement: `printedOpeningBalance` and `printedClosingBalance` **hand-keyed from the PDF with page references** (Revolut #40: 40.06 → 164.94, p.1 — the key's `bnkchk` has no 202412 row, so the printed opening has no table value; card #37: "Saldo em dívida … anterior 270,03 / actual 619,22"; BPI-DO #39: SALDO ANTERIOR / SALDO ACTUAL 31/07; BCP #36 and BPI-USD #38 likewise), `printsRunningBalance` (#37: false — no balance column), `printOrder` (`oldest_first` / `newest_first` / `sectioned` — the card statement prints by section: PAGAMENTOS, MOVIMENTOS per card, COMISSÕES, JUROS), `hasTransactionDateColumn`. Set by reading the 40 PDFs once (a bounded hand check, recorded with page references), reviewed at R-EX-2.
- `answer-key.corrections.csv` — §5.5, pre-declared rows first (including the 18 defective movement descriptions).

Key statistics that shape the rules: 35 fiscal documents, 109 lines, 197 movements; `accountPeriodRule` R1 12 / R3 12 / blank 10 / R2 1; 6 receipt rows; quantity/unit price on 6 lines, VAT rate on 8; 2 placeholder fiscal ids, 2 placeholder document ids (eSIMGo, Lari); `(movDate, amount, currency)` is unique **within each of the five statements** (0 collisions inside any statement; one pair coincides across statements — Revolut's 2025-09-26 +70,000.00 and BCP's same-day transfer — which pairing, being per statement, never meets).

### 5.3 What is compared (S-n)

| # | Rule |
|---|---|
| S-1 | A **cell** is one (document, field) pair from the scored columns of S-9. Three scores, one per kind: **header** (fiscal documents' header cells), **lines**, **movements** (movement cells **plus the statement cells** `movement_count`, `opening_balance`, `closing_balance`) — each = matched ÷ scored. No single aggregate is the gate (Q-EX-7). |
| S-2 | **Pairing.** Lines: by `line_no` ↔ key `lineNo`; a server-appended `stamp_tax` line is `n + 1` on both sides (§2.6). Movements: by the natural key **`(posting_date ↔ movDate, amount, currency)`** — unique within each of the five statements (pairing is per statement); ties among equal `(date, amount, currency)` are broken by S-11 similarity of the descriptions, then by occurrence order — **occurrence order = the answer's `seq` among the tied rows against the key's `bm_code` ascending among the tied rows, in every `printOrder`** — the FDR assigned `bm_code` top-to-bottom within a day, so within a same-day tie the key's `bm_code` order is print order on a newest-first statement too (Revolut 15 Dec, 19 Aug, 10 Mar, 31 Jan verified); no ties exist on the 40 and the rule serves the §7 fixture; **the description is never a pairing precondition** (the Revolut key's descriptions are the FDR's column-sliced cells with the USD amount and the exchange-rate sub-line, so equality is not computable). Unpaired extraction movements and unpaired key movements are misses on every cell; position is never used. `line_count` is a scored header cell; `movement_count` a scored statement cell (S-1). |
| S-3 | **Amounts on magnitudes with the kind's sign.** Compare `sign_by_kind(doc, line) × \|extraction\|` to the key (2 dp), after applying the function `Split(...)` of §2.6 to the extraction (the same function the server runs: the stamp line, branches 0–3, the parafiscal fold, `VAT := VAT ?? 0`) — **so no header amount is null after the transform**: an unprinted VAT compares as 0.00, an unprinted net on a gross-only document compares as `Total − VAT`, and a `null` in the raw answer never meets a key number; the printed-sign exceptions of §2.6 (a discount line; a `stamp_tax` line on an invoice) compare with the printed sign; quantity/unit price at 4 dp after gross → net conversion when `unit_price_basis = gross`. Statements: native sign, no transform. |
| S-4 | `date_due`: extraction non-null → exact. Extraction `null` → a match only where the key flags `dateDuePrinted = false` — the FDR **assumed** the date (`+30`, or `= DateDoc` on a credit note) — or the row is a receipt whose key `dateDue = dateDoc`; otherwise a miss. An extractor that never returns a due date therefore scores only the rows flagged `false` plus the receipts (the FDR's notes seed 5 + 2 of those flags; the hand check of the PDFs sets the rest). |
| S-5 | `date_pay`: the **derived** value (`payment_proof.kind ≠ none → DateDoc`) compared to the key on the 6 receipt rows; other rows excluded (bank-derived key values are not the extraction's). Reported, not floored (n < 20). |
| S-6 | `service_period`: scored on the 12 **R1** rows only — the derived first/last month (advance/arrears against `date_doc`) must equal the key's `accountPeriod`; on other rows agreement is reported. `account_period`: **the key's own rule applied to the extraction's inputs** — on the 12 R1 rows `AccountPeriodService.Decide` from `service_period` and `date_doc`; on the 12 R3 rows the day-of-month rule from `DateDoc` alone (after the §2.6 fallback — VFX's `date_doc` is null, its `DateDoc` the due date 2026-05-02 → 202604), a printed period on such a row (MEO, Regus) being reported under S-8 and never penalised; Locarent's R1 rows take the header period §2.2 derives from the identical line periods — compared to the key **only on rows stamped R1 or R3** (24); blank, R2 and R4 rows reported; 2025 rows report-only. Rule labels are taken as stored (I25120001's R2 predates the ACR). **Amended 2026-09-08 (R2-6): `service_period` is reported, not scored.** As accepted, S-6 scored it against the key’s `accountPeriod` computed by `AccountPeriodService.Decide(dd, stated, null)` — which is the first line of the derivation `account_period` is scored by, on the same rows, from the same stated period. The two cells therefore agreed by construction on any answer that states a period, and all twelve did. It was a cell that could not miss, and twelve of the eighteen header cells the S-10 correction added were these. The scorer was faithful to the rule; the rule was measuring nothing. It moves to S-8, reported beside the score. |
| S-7 | Movements: `posting_date` ↔ `movDate`; `embedded_date ?? transaction_date ?? posting_date` ↔ `docDate`; `amount`; `currency`; `description` (S-11); `running_balance` only where the key's `printsRunningBalance` is true (card statement #37: false — FDR-computed); `period` via the derivation. Statement: `opening_balance` ↔ the flags file's `printedOpeningBalance` and `closing_balance` ↔ `printedClosingBalance` — **never against `bnkchk`**, a per-period table that has no row for a statement's first period on Revolut (printed 40.06, `bnkchk` starts at 202501 with 30.06) and whose 202602 opening on the card (599.30) is not the statement's printed 270.03. Worked cases: Revolut 40.06 → 164.94; card 270.03 → 619.22, with V-14 holding on native signs (270.03 + 349.19 = 619.22). |
| S-8 | Reported, never gated: `item_candidates` hit rate; quantity/unit price/VAT-rate fill rate; `description_printed` similarity; `not_printed` agreement with null keys; `service_period` agreement outside R1; exact-match rate of movement descriptions. |
| S-9 | **Scored header cells** (fiscal documents only — a bank statement has no header cells; its `statement` cells are `movement_count`, opening/closing per S-7): `document_id, date_doc, date_due, date_pay*, currency, net_amount*, vat_amount*, total_amount, fiscal_no` (issuer on I / recipient on R **by the key's flow**, only where the key's `printsIssuer/RecipientTaxId` is true; **compared with `CompanyMatcher.SameTaxId`** — internal, `InternalsVisibleTo` the test and bench assemblies (§4.3): whitespace, punctuation and case ignored, a two-letter country prefix tolerated on either side — since the keys carry the FDR's prefix and the documents print "NIPC: 500 940 231" or "19.628.811/0001-60"), `company` and `origin_class` via the gate (only where `printsRecipientTaxId` on I rows / `printsIssuerTaxId` on R rows is true), `document_type` (doc_type → DOCTYP name), `account_period*`, `service_period*`, `line_count` (**compared after `Split`**, so the appended stamp line counts on both sides: #6 3, #25 2, #31 2). `net_amount`/`vat_amount` are scored on every fiscal row **after the `Split` transform** (S-3) — including #6, #25 and #31, whose headers the function reproduces (§2.6). `company` on a both-match row is scored against the key under Q-EX-23's recommendation where the key's book is the issuer's (#29: GOTT) and **reported, not scored, where the key's book is the recipient's** (reserve R3, I26070074: the FDR's second leg, which Apollo does not answer); under the alternative neither is scored. **Line cells:** `net_amount, vat_amount, total_amount, quantity*, unit_price*, vat_rate*`. **Movement cells:** S-7. (* = conditional.) |
| S-10 | **Gate:** header ≥ 95 %, lines ≥ 95 %, movements ≥ 95 %; a per-field floor of 85 % on any scored field with ≥ 20 cells; fields under 20 cells reported. **Amended 2026-09-08 (C-2 = E-2, found by both reviewers independently): the ≥ 20-cell rule belongs to the floor and to nothing else.** A kind’s rate is matched ÷ scored over **all** that kind’s cells, as S-1 says and as Q-EX-7 says of the statement cells inside movements. The scorer had been tallying each kind over only its ≥ 20-cell fields, which permanently exempted `date_pay`, `service_period`, `quantity`, `unit_price`, `vat_rate` and the three statement cells from every gate, and let a kind with no such field report "not gated" while the run printed PASSED — which is what the pre-ruling reserve report did over a lines rate of 52.94 %. **And the gate is over the sample of §5.1, never over one sitting:** a fiscal sitting has no movement cell and a statements sitting has no header or line cell, so neither can meet three gates. A kind with zero scored cells is a gate *failure* with that reason, and the gate is read off the combined report (§5.7). The reserve set (§5.6) **was** run once, and then — against this clause — a second time after its keys had been amended on the strength of its first answers (D-EX-7): its result is reported beside the two sittings as a measured run, never as a held-out one. A reserve field under 85 % with ≥ 20 cells blocks the gate until explained. |
| S-11 | Movement `description`: a match when the N-4 token overlap (`\|A∩B\| ÷ \|A∪B\|`) ≥ 0.9 or one is a prefix of the other after N-4 (the FDR sliced descriptions by fixed column positions); exact-match rate reported (S-8). The same similarity is S-2's tie-break among equal `(date, amount, currency)`. The 18 key descriptions that carry column-sliced fragments (§5.5) are scored against the corrected value, i.e. what is printed. **Amended 2026-09-08 (C-26):** the prefix rule needs the shorter token list to cover at least **half** the longer one. Without a bound, a one-token answer matched any key description beginning with that token, so a systematically truncated description would have read as a pass on a floored field of 202 cells. No real description changed side: the statements set matches 1349 either way. **Further amended 2026-09-08 (R2-8): the bound is 3 tokens and a quarter of the characters, not half the tokens.** Measured over the sixteen real column-sliced rows §5.5 exists for, the printed text covers 0.32–0.44 of the key’s tokens — so the half-token bound written this morning would have refused fifteen of the sixteen cases the rule was written to accept, while the two truncations it is meant to catch sit at 0.07 and 0.13 of the characters. The test asserts that band rather than the constant. |
| S-12 | **Summarised key lines (D-EX-6).** Where a document carries the flag `keyLinesSummarised`, the key’s line list is a summary of what the page prints and pairing by `line_no` would compare two different shapes. The line cells are then three: `lines[].net_amount`, `lines[].vat_amount`, `lines[].total_amount`, each the sum of that column over the key’s lines against the sum over the answer’s (after `Split` and S-3 signs). `line_count` matches when the answer returns **at least** as many lines as the key. A finer reading of the page is therefore right; an answer that returns fewer lines, or whose sums miss, still fails — and a document without the flag is untouched, so the merge of I26070005 is still scored line by line. Set only by an owner ruling under §5.5. |

### 5.4 The gate as a scored field

`company` and `origin_class` are derived by the extended `CompanyMatcher` from the extraction's identities against the candidate list **built from the keys' `company.{code,name,taxId}`** (six companies across the 40) — the bench never opens a database connection and never reads a connection string (§8). #22/#23 discriminate; #29 is the both-match case (Q-EX-23); #17 (Regus, no id printed) and #13 (Alibaba) are excluded by the flags and their triage outcome reported.

### 5.5 Answer-key corrections

A miss may be appealed only with a page reference showing the document prints what the extraction returned (or prints nothing where the key holds a value). Each accepted correction is a row in `answer-key.corrections.csv` (`entry_code, field, key_value, corrected_value, page, reason, decided_by, date`); the corrected key is what the score uses; the count prints on the report. **Pre-declared at RED:** ~~I24120001 `fiscalNo`~~ — **withdrawn at the R-EX-2 hand check** and never written to the file: the NIPC is printed, in the footer band (corrected 2026-09-08, R2-13; the ruling is in `answer-key.flags.json`). I26070005 `fiscalNo` (not printed); I26050010 `dateDoc` (not printed; key = due date, scored via the §2.6 fallback); **I26070079 `dateDoc` 2026-07-14 → 2026-07-22** (p.2 "Data de Fatura"; the key's date is the billing-period end from the conta-corrente block; a blank-rule row, so `account_period` is unaffected); **the 16 defective movement descriptions** (corrected 2026-09-08, R2-13: the file holds 16, not the 18 this sentence claimed — 15 Revolut rows and 1 BPI row. The two "otherwise column-sliced" Revolut rows the old count added are among the fifteen dates listed here, counted twice) — 15 Revolut rows whose key `description` carries the FX sub-line and the USD amount ("… $127.51 Taxa de câmbio 1 EUR = 1.038078 USD, Taxa: 5.00"; 31 Jan, 14 Mar, 7 Apr, 8 May, 29 May, 13 Jun, 17 Jul, 7 Aug, 19 Aug, 12 Sep, 8 Oct, 14 Oct, 3 Nov, 12 Nov, 5 Dec), 2 Revolut rows otherwise column-sliced (found by page reference at RED), and 1 BPI-DO #39 row (2025-07-30, −2,186.06) carrying an amount fragment ("… FAT-20250422904233 -2 500,00 USD") — each a row keyed by `(movDate, amount)` with its page reference and the printed description as the corrected value, so S-11 scores against what is printed; 16 of the ≈ 1,380 movement cells (≈ 1.2 %), counted on the report like every correction; and **#31 I25040004's lines** — the key's stamp line −17.75 folds a 5.37 parafiscal surcharge into the stamp duty against SKILL.md §6, so the corrected key is stamp line −12.38 (the printed "Imposto de Selo") and item line −143.02 (= −137.65 − 5.37), page 1.  **Ruled after the sittings (D-EX-6, 2026-09-07):** I26030019 `documentId` `PSRS2` → `NCPSRS2`; I26050003 `fiscalNo` `GB12465777` → null; I26070026 `documentId` `590798` → `1254765069`. Each carries the owner’s ruling in `decided_by`, so a correction pre-declared at RED and one ruled on the evidence of a sitting are told apart in the file itself. A correction row replaces the key value for its cell wherever the cell is scored, `document_id` included. More than 5 % of scored **cells** corrected stops the run for the owner's look. **Amended 2026-09-08 (C-18, M-2): the guard is implemented — it never was — and a post-sitting ruled flag counts beside a correction row.** Three of D-EX-6’s seven appeals were applied as flags rather than corrections, and a flag moves the score exactly as a correction does: on the reserve set they took `line_count` from 6/8 to 8/8 and the line cells from 27/51 to 30/30, while being counted nowhere and bound by nothing. A flag carrying a `ruling` member (the ruling that set it, after a sitting) is counted; a flag from the original hand check carries none and is not. The report prints corrections, ruled flags, and the share of scored cells whose key value either replaced. On the 40-document sample that share is 24/2201 = 1.09 %. **Limitation (R3-15):** this share counts surviving scored cells affected by adjustments, not cells removed from the denominator by a ruled flag. It must not be read as the total impact of answer-informed changes.

### 5.6 Reserve (Q-EX-9) — ten documents, fixed now

| # | Entry / file | Company | What it adds |
|---|---|---|---|
| R1 | I26060063 | GOTT | Herdade Malhadinha Invoice-Receipt, 6 % VAT, personal name to the company NIF, advance R1 |
| R2 | I26080031 (`LG001801`) | CONF | EMPCO payable, Confidencial (replaces the EDP CAV twin of #27, which the one-header contract cannot answer separately — Q-EX-24) |
| R3 | I26070074 (`LG001795`) | ITOO | Gott billing Itoorer, the intercompany **payable** leg on Itoorer's book — the gate's both-match case seen from the recipient's side (replaces the Águas do Porto twin of #21 — Q-EX-24) |
| R4 | I26070007 | GOTT | the Locarent invoice #35 annuls |
| R5 | I26070026 | ITOO | CubeSmart USD Invoice-Receipt (receipt rule on an ITOO row) |
| R6 | I26010011 | GOTT | OpenAI, EU-OSS registration `EU372041333`, USD, R3 |
| R7 | I26010042 | GOTT | Farminvest credit note NCGER2600001 (the series of #34) |
| R8 | I25080001 | GOTT | BICS credit note 209295 (the monthly series, R2 entity) |
| R9 | BPI-CC-HEC-EUR_202507.pdf | GOTT | the other card account |
| R10 | BCP-DO-GOT-EUR_202506.pdf | GOTT | a second BCP layout month (449 KB, the busiest BCP file) |

`reserve-set.csv` names each document by entry code **and doclog code**, because two entries carry two live doclog rows: R1 = `LG000015` (not LG000914, the Duplicate copy) and R4 = `LG000795` (not LG001770, the unarchived copy); the ten JSON keys are exported with the same scripts at RED and stored beside the sample; never opened while the package, `EXTRACT.md`, model or effort is being tuned — the reserve was to be the **third, single sitting**. **It was not: see D-EX-7 (2026-09-08).** It was read on 2026-09-07 at 16:13, its keys were amended on the strength of those answers at 22:12 (D-EX-6 wrote three flag rows, one correction and the new rule S-12), and it was read again at 22:50. The second run’s 100 % is a second read scored against a key fitted to the first, so **the set is spent as a control and this slice has no held-out result**; its blind rates were header 76/80 = 95.00 %, lines 27/51 = 52.94 %, movements 158/158. The sentence that follows describes what was intended and is kept for the record, not as a claim of §5.7 under the frozen tuple at R-EX-3.

### 5.7 The bench and its evidence

`tools/extraction-bench/` — a console project `Sibyla.Tools.ExtractionBench` (**not** a test class: `local\test.ps1` runs every test project and a trait filter is not in place; M8), **added to `Sibyla.slnx` under a `/tools/` folder** so the suite builds it (no tests) and a bench that no longer compiles is caught before a sitting — runs `ExtractionRunner` over the 40 (+10) files with `--output-format stream-json` and the production flag set (§4.3, `--no-session-persistence` included), **under a bench `CLAUDE_CONFIG_DIR` and login owned by the owner** (Q-EX-15; the production login under `D:\ApolloData\worker-claude` is never used and never read) **on the pinned binary `ClaudeCliPath = C:\Apps\Sibyla\tools\claude\claude.exe`**, refusing to start on a `CliVersion` mismatch like the worker, needs no database (the company candidates come from the keys, §5.4), **copies each file into its own sandbox** under the bench's work root and writes evidence under `tests/Sibyla.Tests.Argus/evidence/extract-v2/<run>/` (`ExtractionRunner(filePath, sandboxRoot, evidenceRoot, …)`, §4.3) — `git -C D:\fileStorage\repos\invoice-skill-build status --porcelain` being **empty is a bench post-condition**, asserted and recorded — verifies each file's SHA-256 against its key (`fileHash` at the top level of a fiscal key; `statementDoclog.fileHash` on a bank key), scores per §5.3, and writes:

- `tests/Sibyla.Tests.Argus/evidence/extract-v2/score-<yyyymmdd-hhmm>-<apollo sha>-<skill sha>.json` — the cell matrix, corrections applied, the configuration tuple (`CliVersion`, the full model id from `modelUsage`, effort, `SkillTreeSha256`, contract), the bench identity (the owner's config dir, not the tuple), per-document `ProcessingEvidence` with `modelUsage`, `num_turns`, files read, duration;
- the same name `.md` — aggregate per kind, per field, the misses with page refs, fill rates;
- per document `actual/<code>.json` (canonical answers) — the golden of the next run's regression test and the **resume point**.

**The gate is read off a combined report (§5.1, S-10; added 2026-09-08, C-19).** The sittings exist because a 5-hour window cannot hold 50 documents, not because each is separately gated; `Score-Combined.ps1` (the bench’s `score` verb) reads the answers the sittings kept under `score-*/actual/`, scores them as one set and calls no model. It **re-validates every answer against the contract before scoring it** and records each one’s SHA-256 in the report, because those answers are not in git and nothing else would catch one corrupted or hand-edited; it refuses a document two runs answered, refuses to overwrite an existing report without `-Force`, refuses a set with an unanswered key without `-Partial`, and makes a mixed or unknown configuration tuple a **gate reason** rather than a note (Q-EX-14 says a tuple change invalidates the measurement, so a report spanning two of them cannot pass). Added 2026-09-08, R2-9 to R2-12. The R-EX-3 gate is that report’s.

**Plan (F-22).** 50 documents × ≈ 12 turns × ≈ 100k context ≈ one 5-hour subscription window with no headroom. The bench therefore runs in **two tuning sittings** (fiscal documents; statements) while the package, `EXTRACT.md`, model or effort are tuned, and the reserve in a **third sitting under the frozen tuple at R-EX-3** (Q-EX-9; its 10 files ≈ 2 hours). That third sitting was to be single, and was not — see D-EX-7: it was read, its keys were amended on what was read, and it was read again, so **this slice has three measured sittings and no blind control**. The two tuning sittings are named as such here, which is why the reserve was the only blind measurement there was to lose; it resumes from `actual/` (a document with a valid answer is not re-run), treats a usage-limit signal as a stop (not a 10-minute pause: `LanePauseMinutes` does not apply to the bench, which waits for the window's reset time from the CLI's message), and records start, end and every attempt. Attempts: up to `MaxAttempts` = 5 per document, statements per §4.3.

## 6. Persistence hand-off — the following slices, named

1. **Resolution (P2-05 rules).** `CaptureFacts` gains the header, lines and statement; `DocumentCaptureService.RegisterAsync` runs the gate and the router — note it **refuses while sync runs exist for the owner** (C6, `DocumentCaptureService.cs` 44–47), so on tenant #1 the persistence slice lands after cutover or under the sync-era exception the owner rules then; `DocumentEntryService.EnterAsync` receives a draft whose lines carry `ItemCode`/`EICode` only from a known trio, every unresolved line a reported exception, never a guess. Bank: `statement.iban`/`account_number_printed` → BNKACC, `BMCode` minted, `CashDelta`/`Direction` per §2.4 (Apollo's `inflow|outflow|zero`, `Bnkmov.Direction` required), `RunningBalance` (non-nullable) = printed, else **computed from the opening balance by the chain** and flagged "balance computed"; the duplicate-movement tuple check; BNKCHK continuity per period; the `bank_statement` branch of Q-EX-10; the `ToCashDelta("CC")` sync defect raised separately (§3 #15). **Register fiscal-key guard (D-EX-5):** the gate's lookup runs once more on the corrected values before `EnterAsync`; a match is a hold, never an entry.
2. **Persistence.** The FDR write path unchanged; `Doclog.DocDate` per Q-EX-13; `AccountPeriodRule`/`Evidence` stamped; the stamp-duty split and the signs applied per §2.6; `Fdcdtl.Quantity/UnitPrice/VatRate` stored as given (P2-05b: no defaults).
3. **Correction form, lines section** on the Uploads page: the v2 header form of §4.7 plus an editable lines grid and a movements grid, reconciliation shown live, the `CorrectedJson` discipline kept.

## 7. Tests and oracles — RED before code

| Oracle / test | Location | What it proves |
|---|---|---|
| Golden accepted answers (6, hand-authored to the key): #2 Continente (2 VAT-rate lines per doctrine (f); header `net_amount` 60.55 / `vat_amount` 13.56 = the summary's column sums), #6 Tranquilidade (printed net/vat null, duty −0.03), #10 AWS (the nine lines converted from USD at the printed rate 0.86340951809: 509.01 → 439.48, 117.07 → 101.08, 10.80 → 9.32, 2.48 → 2.14, 0.08 → 0.07, 0.02 → 0.02, …; each line's total = converted net + converted VAT, so line 5 is 9.32 / 2.14 / **11.46** (not 11.47 from the printed USD 13.28); Σ net 448.87 against the header 448.88, inside V-9), #35 Locarent NC (header period from the identical line periods), #37 BPI card, #40 Revolut | `tests/Sibyla.Tests.Platform/golden/extract-v2/accept/<code>.json` + `.canonical.json` | `ExtractionContractV2Tests`: validates, canonicalises byte-for-byte, round-trips |
| Rejection corpus, one file per V-rule plus §4.5's hostile-answer set, plus `V-8-third-shape.json` (the scoring row's reject case: net 100.00, vat 23.00, duty 4.00, total 129.00, no printed stamp line, `reconciliation_note` null → neither V-8 shape, refused) | `tests/Sibyla.Tests.Platform/golden/extract-v2/reject/<V-n>-<name>.json` + `expected.txt` | `ExtractionContractV2Tests.EveryRejectionNamesItsRule`; V-11/V-18/V-19 as accept-with-finding |
| Skill package manifest | `…/golden/extract-v2/skill-package.manifest.txt`, `manifest.json` | `SkillPackageTests`: the committed package equals a fresh build from the pinned commit (the skill-build path from the env var `SIBYLA_SKILL_BUILD_PATH` or `local/skill-build.path`; **absent → one explicit failure naming the missing source, never a silent skip**) and hashes to the golden; one changed byte changes the hash; CRLF/LF alike; every package line ≤ 1,900 chars; reflowed lines listed with source hashes; `CLAUDE.md`/`.claude` refused; heading anchors match; personal-name masks listed. The published tree is **not** this test's: `publish-release.ps1` checks it after every publish (§4.6) |
| Evidence and start-up | `ProcessingEvidenceTests` (extend); `WorkerStartupTests` | `JobId` (nullable; an old element without one reads back and compares unequal), `SkillCommit`, `SkillTreeSha256`, `CliVersion`, `Model`, `Effort`, `ModelUsage`, `TimeoutSeconds` on every attempt; evidence files under `evidence/<jobId>/`; `PromptSha256` identical for a `.pdf` and a `.png` sandbox copy; a host whose `claude --version` (first token) or package hash differs from its options **fails in `StartAsync` before any slot starts and `Host.Run()` exits non-zero** (the fake CLI reports a different version; a fake that never answers exhausts the budget with `StartupCheckSeconds = 1`) |
| Worker gate by contract id | `tests/Sibyla.Tests.Platform/ExtractionResultIdentityTests.cs`; `QueueWorkerGateTests` (DB-backed like `ProcessingEvidenceTests`, driving the internal **`CompanyGate.ApplyAsync(conn, tx, ownerId, intakeId, resultJson)`** with canned v1/v2 answers through `ExtractionResult.ReadIdentities`) | v1 and v2 answers both assign; #22 → Gott, #23 → Itoorer, #17 → triage; **#29 (both match) → Gott as R/Internal with both candidates in the audit detail** under Q-EX-23's recommendation (the alternative's expected value, triage with both named, is the test's other branch, enabled by the ruling); a `HeldForPerson` row still gets its assignment; `SameTaxId` on "500 940 231" ↔ "PT500940231" |
| Review page and holds | `tests/Sibyla.Tests.Browser/DocumentsReviewV2Tests.cs`; `IngestionServiceHoldTests` | a v2 row renders header, lines and movements; a correction stamps the source contract id; a `HeldForPerson` statement lists its `hold_reason`, says no completion path exists and **its submit is refused**; a held fiscal document's correction moves it to `Processed` and clears `hold_reason`; a held row ruled "not a duplicate" returns to `HeldForPerson`, never `Processed`; **a `timeouts:2` hold with `result_json` null accepts a hand-keyed correction and moves to `Processed`** (the statement refusal is decided by `result_json.doc_type`, so it cannot apply); a superseded `CorrectedJson` renders grey with its contract stamp after a re-extract; **after a re-extract both jobs' evidence files exist under `evidence/<jobId>/` and the old `evidence_json` element's `RawStdoutSha256` still matches its file**; the first re-extract gets key `…:<contract>:2` and the second `…:3` (the intake's `storage-transfer` job not counted) |
| Timeouts | `ClaudeCliTimeoutTests` (fake CLI, DB-backed like `ProcessingEvidenceTests`; drives the internal **`JobCompletion.CompleteAsync`** and **`TimeoutLaneMonitor.Record`** of §4.3) | `RunAsync` receives 900 on a first attempt and 1,350 when `evidence_json` carries an element with `JobId == job.Id && ExitCode == −1` — **the test seeds elements of two jobs** and the other job's timeout is ignored; the second timeout returns `JobOutcome.Hold` and `JobCompletion.CompleteAsync` writes `docint` status 9 with `result_json` null and `hold_reason = timeouts:2`, **`jobque.state = 2`, `last_error` = the reason, audit `job.hold`** — the test asserts the row — and runs `CompanyGate`; a non-timeout failure between two timeouts does not reset the count; `TimeoutLaneMonitor.Record(true)` twice in a row (from either slot) returns `pause = true`, a non-timeout in between resets it; the "Claude unavailable/limited" pause is unaffected |
| Permissions | `ClaudeCliPermissionTests` (asserting on the static seams `ClaudeCliProcess.BuildArguments` and `PermissionsFile.Build`, §4.3, under the worker's `InternalsVisibleTo`) | the argument list is exactly the §4.3 flag set **in the §4.3 order, `-p` first** (`--safe-mode` included; no `--fallback-model`, no `--allowedTools`); the prompt names the sandbox copy with its real extension — **one case with a `.png` input** asserts `document.png` in the prompt and the same `PromptSha256` as the `.pdf` case; `--settings` points under `evidence/<jobId>/`, outside the sandbox; the generated `permissions.json` allows exactly the two roots and denies the enumerated list (Windows syntax per the R-EX-2 probes (a′)); `PermissionsFile.Build` is passed two fake sibling release directories and the test asserts both deny lines; `BuildArguments` with `outputFormat = stream-json` carries `--verbose` only when `ClaudeCliProcess.StreamJsonNeedsVerbose` is true — the test asserts the list for both values of the constant (`false` at RED) |
| Scoring harness | `tests/Sibyla.Tests.Argus/ExtractionScoringTests.cs` over `golden/extract-v2/answer-keys/*.json`, `answer-key.flags.json`, `answer-key.corrections.csv`, synthetic `actual/` fixtures | S-1…S-11 on fixtures with known miss counts: **natural-key pairing on a shuffled Revolut key whose rows include at least one key description carrying the FX sub-line ("… $127.51 Taxa de câmbio …") paired to an honest `description_printed`**, plus a same-day same-amount pair broken by S-11 and then by occurrence order (the answer's `seq` among the tied rows against the key's `bm_code` ascending among them, on a newest-first fixture — the tie pairs A with A, not A with B); `Split` on the real cases — #6 (net/vat null, total 767.02, duty −0.03 → branch (0), Net 767.02, **VAT 0.00**, lines 634.72 / 132.33 / −0.03 with the stamp line's `vat_rate` 0, `line_count` 3 after `Split`), Lari #16 (net/vat null, total 372.30, no duty → Net 372.30, VAT 0.00), VFX #12 (clause (h): lines 1,990.00 / 41.78), Alibaba #13 (clause (i): total 1,316.23, four lines, net = total), Águas do Porto #21 and EDP #27 (clause (j): one line each — 62.51 / 3.76 / 66.27 and 28.07 / 4.16 / 32.23, the EDP net being the VAT block's base sum 13.52 + 14.55), Lari #16 (`document_id` null against the placeholder key), #25 (inputs net 382.82 **and** net null, vat null, total 411.54, duty 19.15, other 9.57, one item line 382.82 → Net 411.54, lines 392.39 / 19.15 both ways), #31 (inputs net 137.65 **and** net null, vat null, total 155.40, duty 12.38, other 5.37, one item line 137.65 → Net 155.40 signed −155.40, lines −143.02 / −12.38 = the corrected key, both ways) — and on **synthetic fixtures** for the printed-net branches: (1) net 100.00, vat 23.00, duty 4.00, other null, total 127.00 → Net 104.00, VAT 23.00, stamp line 4.00; (1′) net 100.00, vat 23.00, duty 4.00, other 2.00, total 129.00 → Net 106.00, VAT 23.00, item 102.00, stamp 4.00; (2) net 100.00, vat 27.00, duty 4.00, other null, total 127.00, one item line 100.00 whose `vat_amount` is 23.00 (the true VAT) → V-9 passes on the raw answer (Σ lines.vat 23.00 + |duty| 4.00 = 27.00, the branch-(2) clause), Net 104.00, VAT 23.00, stamp line 4.00; and (3) net 100.00, vat 23.00, duty 4.00, total 130.00 → no header adjustment (Net 100.00), stamp line still appended (Σ lines 104.00), a finding carrying the 4.00 difference and no failure (a `Split`-level fixture: as a raw answer it fails both V-8 shapes and needs a `reconciliation_note` to pass V-12); **the guard fixture** — net 104.00 including a printed `stamp_tax` line 4.00, vat 23.00, duty 4.00, total 127.00 → V-8 (its second shape) and V-9 pass, `Split` makes no adjustment, header = Σ lines, no finding; **header = Σ lines asserted in (0)–(2), the difference asserted as the finding in (3), none in the guard fixture**; and the third-shape reject case (net 100.00, vat 23.00, duty 4.00, total 129.00, no printed stamp line, `reconciliation_note` null → neither shape, refused), which lives in the Platform rejection corpus and is listed on that row; the statement cells on the Revolut (40.06 → 164.94) and card (270.03 → 619.22) printed balances; S-4's three branches; S-6 on an R1, an R3 and a blank row; S-11 at 0.89 vs 0.91; the ≥ 20-cell floor rule; the 18 description corrections applied |
| Evidence scan | `EvidenceSecretScanTests` | the scanner catches each marker class on synthetic files and never opens a secrets path |
| Gate derivation | `CompanyMatcherTests` (extend) | two-sided match; both-match → pair |
| Ambiguity tests | `AccountPeriodTests` (extend) | R1 advance/arrears from `service_period`; credit note → reversed document's period; R3 when null; `DateDoc` fallback |
| Bench evidence | `tests/Sibyla.Tests.Argus/evidence/extract-v2/…` (§5.7), `hostile-documents-run.md`, `answer-key.meta.json`, `answer-key.flags.json`, `answer-key.corrections.csv`, `reserve-set.csv` | the run records |

RED means: the goldens, keys and flags exist and the tests fail because `ExtractionContractV2`, `SkillPackage`, `ExtractionRunner`, the identity reader, the page and the scorer do not; the RED tree's fingerprint is recorded before the first GREEN commit.

## 8. Review checkpoints

| Checkpoint | Gate | Reviewers |
|---|---|---|
| R-EX-1 spec | Rounds until ACCEPT (Critical 0 / High 0 from both); adjudications in `apollo-argus-extraction-v1-spec-review.md`; the owner rules Q-EX-0…23 | two independent reviewers, before any code |
| R-EX-2 RED | §7's oracles exist and fail for the right reason; the keys copied and the flags file filled from the PDFs (printed balances with page refs); the reserve keys exported by doclog code; the package built from the pinned commit, committed, with its manifest; **the Windows syntax of the `Read(...)` allow/deny rules and the full flag set verified on the pinned CLI 2.1.259** — probe (a) reads a package file and the sibling `<release>\appsettings.json` and records both outcomes, probe (a′) denies a file planted inside the sandbox by rule and shows it refused while `document.pdf` reads, probe (b) plants a `CLAUDE.md` above a temporary sandbox root and shows it absent from the `stream-json` trace under `--safe-mode` with package reads still working, and the record says whether `--settings` applies under `--safe-mode` (§4.5); the pre-declared corrections recorded (corrected 2026-09-08, R2-13: the file holds 26 rows - 3 header pre-declared at RED, 16 movement descriptions, 4 line rows for #31, and the 3 the owner ruled in D-EX-6 after the sittings; the old "4 + 18 + #31" counted a pre-declaration that was withdrawn and two movement rows twice) | two reviewers |
| R-EX-3 GREEN | suite green; bench report ≥ 95 % per kind with the floors; reserve reported; hostile-answer corpus green; hostile-document run (including the out-of-sandbox read and the web-egress document) recorded under the production flag set with a clean evidence scan; **the configuration tuple named — `CliVersion`, the full model id, effort, `SkillTreeSha256`, contract** — and the bench identity recorded; web and worker in the one release, web before worker in the module's plan (§4.6); a real intake row's evidence shows the tree hash. **Amended 2026-09-08 (M-6): this list mixes two moments.** Everything up to and including the tuple is evidence the reviewers read *before* the release; the last two rows — the one release, and a real intake row carrying the tree hash — cannot exist until it has happened, and the owner guide rightly puts the release after the checkpoint. So the checkpoint closes on the pre-release rows and the owner confirms the last two from the deployed system; a reviewer who reads the row as one list will find two of its own gate items unmet and be right. | two reviewers on the pre-release rows, the owner on the last two, then the owner's word opens the contract to gateway traffic |
| R-EX-4 | the resolution + persistence slice (§6) — its own spec | — |

**Operational restrictions while this is built:** no production deployment of web or worker with v2 before R-EX-3; `local\secrets`, `C:\ProgramData\Sibyla\secrets`, `D:\ApolloData\worker-claude`, `D:\ApolloData\dp-keys` untouched and never read by the bench, the scanner or the CLI's tools; the bench opens no database connection and reads no connection string (its companies come from the keys) and reads the skill-build tree at the pinned commit only; the bench never uses the production CLI login; the invoice-skill-build repository is not modified; the answer keys under `D:\fileStorage\tmp\apollo-extraction\answer-keys` are copied, never edited — corrections are rows in `answer-key.corrections.csv`.
