Migration applied to production, in the only order that does not break the
promote flow:
1. Created `ai_agent_prod_prod_write` (id=5) with the narrow `prod-write` scope —
invoices, payments, and document submission (needed by builddoc to regenerate
a modified invoice's PDF). Verified functionally: reads pass, DELETE on an
invoice returns 403.
2. Repointed the promote pipeline at that user's key. It no longer borrows the
read skills' credential; if the key is absent it dies with the provisioning
command rather than silently falling back.
3. Revoked 12 write/delete rights from `ai_agent` (id=3), the credential every
read skill holds: create/modify on customer AND supplier invoices,
thirdparties, contacts, thirdparty payment details, proposals, exports,
accounting links — and delete on proposals, events, and GED documents.
Verified after: invoices, thirdparties, contacts, products, proposals, supplier
invoices and bank accounts all still read; creating an invoice returns
`403 Forbidden: Insuffisant rights`. The documented posture and the real one
finally agree.
scopes.ts corrected against the live instance: 262 is NOT "créer/modifier les
produits" as the first catalogue guessed but the `voir_tous` ACL extension — a
READ right the skills depend on (without it, list endpoints return empty arrays
instead of 403). Revoking it would have silently blinded every read skill. This
is why the audit reads labels off /user/perms.php rather than trusting ids in
code. The READ_ONLY baseline is now the audited read surface (35 rights), not a
guess.

The discipline (ADR-0003, the promote flow, the operating rules) was written
down and still depended on whoever was driving choosing to follow it. On
2026-07-25 an agent session wrote five documents into the production ledger
through direct API calls, bypassing the promote flow entirely — a correct result
reached by a path nobody could audit. A rule an operator can skip is a
recommendation.
The five stages are now chained by artefacts on disk. Each refuses to run until
the previous produced its file, and the file says what it needs to hear:
rehearse (sandbox, host-guarded) -> judge --pre -> gate (human) -> apply
(prod) -> judge --post. The gate binds to a manifest digest, so approving a
change-set approves THAT change-set.
An op is defined ONCE, as an API call, and replayed on the sandbox then on
production — because the first design described each write twice (a sandbox
script input and a prod API body) and the pre-gate judge immediately caught them
diverging: the rehearsal was creating a EUR invoice with no due date while
production would have received a USD one at 60 days. Two descriptions of the
same write are two things that can disagree.
Judges are context-free, cross-family per the PRD qa-strategy rule, and
advisory: a BLOCK still lets the operator approve, and the override is recorded
with their name. Blocking authority stays with the human gate and the host
guards — an LLM verdict never silently starts or stops a production write.
Verified end to end against the real 24/08 change-set (M3 deferred, USD 3,000):
- pre-gate judge (Mistral) returned BLOCK twice, correctly — first on the
sandbox/prod divergence, then on a duplicate left by a repeated rehearsal;
- apply refuses after a rejected gate;
- apply refuses without ARCO_PROD_CONFIRM;
- editing an amount after approval invalidates the gate on digest mismatch.

- runs/2026-07-18/: the 8 sha256-pinned verifier transcripts (4 runtimes ×
2 tests), blind-judging verdicts (2 independent judges per cell, unanimous),
the erp#56 builder-bench journal + prompt + caps, and the evidence README
with the parity table.
- run-verifier.sh: mistral runtime drops the tool-filter flag (--enabled-tools
with a no-match pattern hangs vibe 2.21.0); plain -p with --max-turns 1.
Verdicts: Mistral (vibe -p, mistral-medium-3.5) and Ornith 35B (hermes MLX)
reach verdict parity with the Claude baseline on both tests → admitted to
verifier duty. Qwen2.5-7B-4bit fails both → the honest small-model floor.
Builder bench: erp#56 completed by the Mistral runtime, 0 code corrections,
261 s, acceptance run clean (0 bank-UNKNOWN) → merged as PR #68.
Closes#63 (with the paired factory qa-strategy PR).

The harness layer (builder sessions, cold verifiers, evidence flow) gets a
committable home, per the PRD model-fleet § harness portability and erp#63:
- fleet/harness/verifier/: the two canonical verifier tests (locate-test,
cold-reader backlog audit) with pinned inputs, verbatim prompts, ground
truth and pass rules — judged context-free, never self-graded.
- fleet/harness/bin/run-verifier.sh: runs a test against any OpenAI-style
local endpoint (Ornith/MLX) or vibe -p (Mistral); emits sha256-pinned
JSON transcripts.
- fleet/harness/bin/vibe-builder.sh: the bounded shell for scoped builders
and recurring tasks — refuses the trunk (linked-worktree guard), hard
--max-turns/--max-price caps, full JSON journal per run.
- fleet/README.md layout + AGENTS.md Fleet section updated in the same
change (same-change freshness rule).
Part of erp#63 (harness portability spike, D2).
