Neither weakens an assertion; both were rewritten to +assert the new guarantee. + +1. **`tests/test_tc_run_cli.py`.** Its injected `RecordingClient.run_task` has a + fixed signature that the new `snapshot`/`decision` pair breaks, and + `test_terminal_routes_exit_3_without_backend_execution` patched + `triage_core.client.choose_resilience_route` — a call the governed path no + longer makes, so the patch had become a silent no-op. The test now drives the + router at the seam, and its `deterministic` arm asserts the stronger new + fact: an unbindable member falls through to the next already-authorized + envelope member rather than executing anything. +2. **`tests/test_tc_run_plan_cli.py`.** The governed snapshot bounds an explicit + task ID to letters, marks, numbers and `._:+-`, so `--task-id 'tâsk-☃'` is now + rejected at the seam instead of rendered. The unicode-escaping test keeps its + snowman in the source path and the backend model and uses a non-ASCII + *letter* in the task ID, so the escaping it exists to prove is still proven. + +### Behavioral changes an accepting reviewer is approving + +- **Capability no longer reaches route policy** (Resolved Question 1, as + recorded). Both preview and execution now form the decision with + capability-free availability. A run whose local capability is unknown produces + a decision naming local routes and then fails at binding, where previously the + router resolved to no local route earlier. The observable terminal outcome for + `tc run` is unchanged — a local-only run with no usable local capability still + exits 2 through the existing local-route guard — but the *reason* now arrives + at binding rather than at routing. +- **`tc run --plan` output gains one line**, + `permitted_fallback_envelope`, and its `route_required_checks` line now lists + the governed verification codes rather than the router's (previously empty) + list. The `governed_run_plan.v1` contract, its field set, `plan_body_digest` + and `artifact_byte_digest` semantics are unchanged, and `decision_id` is + absent from the artifact. +- **Plan-artifact digests change value.** The artifact's `assembled_input_binding` + now digests the snapshot's authoritative assembled bytes + (`instruction + b"\n\nDATA:\n" + task_data`) instead of a second independent + `f"{prompt}\n{data}"` assembly. This is the point of the slice — one assembly + rule for digests and execution alike — and it means a digest recorded before + this change will not match one recorded after. No schema version changes. +- **`--model` is now validated on the execution path too.** An unknown profile + exits 1 rather than being ignored, because a governed decision requires a + resolved context/model profile. +- **An execution-path privacy failure now reports bounded finding codes.** The + seam's scan runs before `verify_packet`, so the message is the plan path's + `finding_codes=` form rather than the scanner's free text. Exit code is + unchanged at 2. +- **A local-only run whose ethical firewall triggers now exits 2 rather than 3** + in the narrow case where the firewall triggers but deterministic risk is low. + The decision forces `human_handoff`, and the pre-existing local-route guard + treats a non-local route on a local-only packet as fail-closed. Both are + non-executing terminal outcomes; exit 2 is the more conservative of the two. + +### Repairs after the `909838f` acceptance review + +Acceptance was withheld at `909838f` with three required repairs. All three are +implemented. + +**Repair 1 — scope record.** No implementation allowlist was ever granted, so the +lifecycle record was corrected rather than reconstructed. See **Authority +record** in **Status**. The repair recorded the defect and named the dispositions; +the operator subsequently chose corrective ratification, which is recorded +verbatim there. The defect itself is preserved, not closed retroactively. + +**Repair 2 — remaining decision-bearing recomputation removed.** Both offenders +are gone from the governed path. + +*`ProjectSteward`.* The governed path now consumes `ethical_firewall` from the +decision and never calls `evaluate()`. **A claim in the previous revision of this +record was wrong and is corrected here:** it said removing the steward "would +silently drop the credit-allowance and energy gates." It would not. +`ProjectSteward.__init__` does `self.budgets = budgets or {}`, so `ProjectSteward()` +and `ProjectSteward(budgets={})` are the same object state; `token_credit_allowance` +is therefore always `0` on this path and the credit gate is unreachable, and the +energy and validation gates require a non-empty `completed_orders`, which +`run_task` never supplies. The only live output was the ethical firewall on the +prompt text — which the decision already carries as a first-class field. So there +was no gate to lose, and the recomputation was pure duplication. The reviewer's +reading was correct and mine was not. + +*`SpecialistRouter.route_task`.* Not invoked at all on the governed path. Its +offload verdict is a second policy decision: two of its three offload branches +turn on a live `is_internet_available()` probe, which Resolved Question 1 +forbids from answering what route a task receives, and its third branch — high +risk — the decision already expresses as a preferred `human_handoff`. Only its +two execution *parameters* were still needed, and both are pure functions of the +classification the decision carries. `client._governed_execution_parameters` +returns them, and a parametrized drift guard asserts they equal `route_task`'s +own tables for every category the deterministic classifier can emit. The +executed timeout is now exactly the `specialist_timeout_forecast_seconds` the +preview published, so the budget a reviewer reads is the budget the worker gets. + +Consequences worth naming: `tc run` no longer emits a `specialist_offload_decision` +event, because no specialist offload decision is made; the CR-DD-018 evidence +contract is untouched and still governs the direct-library path. And a +medium-risk or large-context task no longer offloads on the basis of live +connectivity — which is the corrected architecture, not a lost feature. + +*`verify_packet` remains,* and is the one survivor. It produces the +`VerifiedTaskPacket` type token the routing boundary requires, so it is +validation rather than recomputation, it cannot alter policy, and it is itself +one of the decision's `required_checks`. + +**Repair 3 — ethical-firewall exit 3 restored.** A firewall handoff is a governed +terminal outcome, not an unavailable route, and it now returns `handoff_required` +with a `worker_result` record at exit 3 rather than being caught by the +local-only guard at exit 2. The distinguishing fact is the binding outcome, not +the route name: `human_handoff` bound as **primary** with a triggered ethical +firewall is a governed handoff; `human_handoff` reached as an envelope +**fallback** means the authorized route could not bind and stays fail-closed at +exit 2. Both cases are pinned by regression tests. + +One residual asymmetry, flagged rather than changed, and since **settled as +out of scope for this slice** by the accepting reviewer: a **high-risk** +local-only run also routes to a primary `human_handoff` and still exits 2, +because `test_high_risk_local_only_fails_closed_exit_2` pins that as a CR-DD-009 +exit-code contract and it was not a regression this slice introduced. It is +recorded as a separate discovery in **Open Discovery: High-Risk Terminal Exit +Class** below. Folding it in here would have turned a convergence slice into a +semantic rewrite. + +### Where the implementation is narrower than the recommendation + +One item remains, stated plainly rather than absorbed: **`verify_packet` still +runs inside `run_task`**, for the reason given under repair 2.

Volatile facts stay in a validated internal `RuntimeObservation` that subsumes CR-DD-013's capability resolution without re-deriving it; actual backend binding is a filter over the decision's closed ordered fallback envelope, never an injection surface; and bounded `decision_id` linkage rides the existing open route/worker payload extension point with no new ledger schema. Direct `run_task` callers that omit the decision keep current behavior. All three previously open questions are settled by recorded decision: capability evidence constrains execution binding only and never governed-decision formation, so a volatile observation may execute, bind an already-authorized fallback, or fail closed but never invent a route — a deliberate correction to current `tc run` route selection, recorded as such rather than absorbed as an implementation detail; the deterministic classifier is authoritative while any model-assisted classifier stays advisory; and `build_run_plan`'s signature is preserved only if it remains one coherent projection, since a narrow break beats an attractive second integration path. Five approval gates are recorded across two stages: two proposal-stage preconditions — the capability decision and the pre-`planning` seam statement — are satisfied, while three test obligations must be bound by any bounded implementation approval and pass before implementation acceptance, merge, or closeout; those three are replacing rather than deleting the CR-DD-012A integration-absence guard and negative tests for capability volatility and unavailability.
