L08-07 — Qualify two clients, decision receipts, and the inspector #67

Outcome

Prove that Editor and PdfTool clients see the same observation identity, abstention, fallback, and provenance after restart. Ship the decision inspector and trace modeled on jev's inspector: the indexed table, every head's distribution, the selected head, reason codes, latency and token usage, and a pause before handoff that lets the operator stop or choose manually.

Parent and boundary

Parent: #9. Owner: proposed Decision module. This issue owns one bounded slice of Bounded Decision Worker; consume accepted upstream contracts and keep PDF/verdict/publication authority with Core.

Acceptance

• The receipt stores the full request, all raw head answers, the validated selection, provider/model identity, budget use, and timing. Replay reads the receipt; it does not re-ask the model.
• Recorded decision replay is stable even if a stochastic model rerun differs.
• The inspector and the PdfTool trace render the same receipt.
• Failure case: a client-specific cache, a missing receipt, or an inspector that recomputes probabilities cannot count as parity.

Required proof

Two-client installed test, restart, inspector/trace parity fixture, and target-hardware cost report (per-decision latency, decisions per task, tokens). Record the exact source SHA, test command or hosted run, fixture/artifact identity, and any skipped or unavailable lane. Run the repository's mapped proof and check-change gate for a PR.

Handoff

Record changed files, observed result, remaining risk, and a 1–3 sentence anti-slop review. Completion means acceptance evidence, not merely a merged implementation.
