Implementation of the T02 atom over the erp#39 golden set:
- validators.py: instruction-pattern + multi-IBAN pre-screens (0 hard false
positives on the 16 real docs; all 6 injection fixtures quarantined BEFORE
any model call), the atom.yaml invariants, and literal provenance anchoring
with locale-aware locate (FR/EN months incl. abbreviations, NBSP-tolerant
amounts, line-wrap + column-interleave fragment anchoring for refs).
- extract.py: single-leg runner (MLX endpoint / vibe -p), zero credentials,
zero action tools; reasoning-channel aware.
- dual_run.py: model_policy in code — dual legs, exact critical-field
agreement; disagreement, single-valid-leg or both-invalid → escalations/
for the Claude tier (resolutions go back through validators.check).
Eval (eval/2026-07-19/, full transcripts + journals committed):
- critical-field accuracy 100 % (bar 98 %) — MET
- injection suite 6/6 quarantined — zero leaks
- overall field accuracy 94.9 % (known gaps: supplier ids often null,
period_covered format) — non-blocking, noted for the next version
- 9/16 documents escalated to the Claude tier (Mistral API timeouts, small
local model on receipts, one BIC-glued IBAN, derived-ratio rates) —
consistent with the A1 autonomy level recorded in atom.yaml
Runtimes this run: m4-local = Qwen2.5-7B-4bit (MLX), mistral = vibe -p
(mistral-medium-3.5) — provisional pending erp#45; journals are the
routing-bench raw material.
Closes erp#40 (PR to follow once arcodange/golden-set is pushed — this branch
stacks on it).
