Operator requirement (2026-07-11): mechanical measures against
hallucinated values in agent-performed edits. Four deterministic
layers in agent-architecture: (1) no free-text critical fields —
code copies values from validated extraction/bank-feed payloads,
the model never re-types them; (2) provenance anchors per critical
field {source_sha256, raw_excerpt} re-verified by a deterministic
checker against re-extracted source text (locale-normalized);
(3) cross-system corroboration against FRESH bank pulls + arithmetic
/checksum invariants; (4) read-back closes the loop. A failed check
refuses, never repairs. Woven into hub goal, C1 strategy, and QA
write-path (seeded-wrong-value fixtures must FAIL). Proven live:
the books-regularization pack shipped with a standalone
verify-provenance checker — 36 field-level checks green against
source PDFs + fresh Qonto/Wise feeds before the human gate.

New compliance.md leaf: French bookkeeping obligations mapped to fleet
mechanisms — inaltérabilité (L.123-22) via an append-only production
ledger grammar (create/validate/pay/avoir, never mutate a validated
document) enforced by a promote-plan compliance linter; FEC (L.47 A
LPF) with quarterly export + Test Compta Demat validation (accounting-
module binding flagged as unverified gap); piste d'audit fiable (289
VII CGI) framed as a by-product of journals + tx-id reco + monthly
packs; retention, numbering, copie fiable; loi anti-fraude scoped out
(B2B-only) with BlockedLog as sandbox-first belt-and-braces.
New Environments section in agent-architecture: prod = the ledger
(grammar-bound), sandbox = disposable iso-prod rehearsal (exempt, never
wired to production third parties); side_effect_class -> environment/
credential mapping; POCs write on sandbox only; evals target fresh
checkpoints; irreversible-by-design features trial on checkpoints.
Woven through hub (goal, requirement, success criteria, leaves table),
T03/T05/T15 guardrails, QA (linter suite, pure-append snapshots, FEC
cadence, PAF evidence framing), C2, POC-1 exit criteria.

Operator direction: Qonto is the capital-deposit bank, a DGFiP-registered
PA with e-invoicing included in every plan, and the fleet's richest
existing API integration. POC-6 rewritten from shortlist to validation
spike (reception + business-API pull + GED archival + 2027 e-reporting
path for the KM export invoices); C12 residual now names the vendor-
concentration trade-off; terminology refreshed PDP -> PA (renamed by the
administration in July 2025); 2027-09 milestone clarified (e-reporting
for export invoices; emission only if a French B2B client arrives).

The PARA Obsidian vault (arcodange/SecondBrain — git-synced, sb.py
digest/inbox/gitea-ingest jobs on the hermes cron ticker, local Ornith
model, mcp-obsidian access) enters the PRD as a first-class component:
new T17 knowledge capture & retrieval fiche, knowledge-layer section in
the architecture (ERP = book of record, vault = context + institutional
memory, append-only idempotent deposits, trusted-but-stale retrieval),
hermes/Ornith recognized as the resident M4 runtime (D2 leaning, new D7
cluster<->vault access decision), foundation ledger row, diagram +
goals updated (mermaid revalidated, 231 links/anchors re-checked green).

New PRD tree vibe/PRD/ai-back-office/ (hub + 6 leaves + STATUS): task
inventory T01-T16 with mode operatoire, atom/contract architecture on
the ADR-0003 write gate, four-tier model fleet (Claude/Mistral/M4/Pi),
12 challenges with mitigations, POC plan with exit criteria, QA
strategy with autonomy promotion gates. Index row + bidirectional
backlinks (erp guidebook, safe-prod PRD).
