Subject: [PATCH 01/90] fix(ci): restore evidence-only review admission

Reapply the validated admission-only review boundary onto current protected main without reviving one-shot repair artifacts or heuristic outage-domain quotas. Remove candidate-count/account caps, price/ZDR/provider ordering, synthetic priorities, launcher route-count caps, and shared first-come escalation quota. Preserve all five bootstrap credentials while keeping OPENAI_API_KEY-derived models outside orchestrator/free candidate admission.

+- **Date:** 2026-09-01
+- **Status:** supersedes the 2026-08-30 diversity-gate proposal
+- **Subject:** Noema, OpenCode, and Strix route required review through
+  `ContextualWisdomLab/contextual-orchestrator` using `orchestrator/free`.
 - **Decision record:** [`docs/adr/0003-contextual-orchestrator-vendored-free-zdr.md`](../adr/0003-contextual-orchestrator-vendored-free-zdr.md)
-  (2026-08-30 addendum)
-- **Related:** [`docs/product-goal-directive.md`](../product-goal-directive.md) §8
-  and its Follow-up findings note; [`docs/doctoring/noema-orchestrator-free-zdr.md`](noema-orchestrator-free-zdr.md)
 
-## Why this needed reconciliation, not a direct edit
+## Superseded proposal
 
-`docs/product-goal-directive.md` states its own conflict policy: "Where this
-directive and those documents conflict, resolve the conflict and update
-whichever document is wrong — do not silently pick one." Strix's
-`orchestrator/auto` pin is not an oversight; it is an accepted ADR-0003
-decision backed by a specific, dated finding: on 2026-08-29, the DiskSage
-exact-head scan showed every discovered free route sharing the OpenRouter
-outage domain, so a strict `orchestrator/free` pin for Strix (which has no
-provider fallback) would have gone dark on that one provider's outage. Silently
-flipping the pin today, on the strength of a general instruction that does not
-re-examine that finding, would reintroduce the exact single-point-of-failure
-risk the ADR was written to avoid — for the workflow whose job is the org's
-required *security* review. Silently keeping the old pin, on the other hand,
-would ignore a legitimate cost/consistency goal the owner restated today.
+The earlier version of this record correctly observed an outage-domain
+concentration incident, but it proposed automatically switching Strix between
+`orchestrator/free` and `orchestrator/auto` when a
+`free_family_diversity >= 2` condition was met. That cardinality threshold was
+not derived from a reliability model, statistical estimand, authoritative
+standard, or experimentally validated routing policy. It is therefore not a
+permitted decision rule under the organization no-heuristics contract and must
+not be implemented or revived.
 
-## What changed
+`free_family_diversity` or equivalent provider/outage-domain observations may
+remain diagnostic evidence. Diagnostics do not acquire routing authority merely
+because they are deterministic or measured. Any future reliability-aware model
+selection must identify its estimand and be independently evaluated rather than
+turning an incident count into a threshold.
 
-`scripts/ci/contextual_orchestrator_review_policy.py`'s
-`build_zdr_prioritized_catalog` now reports `free_family_diversity`: the count
-of distinct outage-domain provider families (`provider_family`; the primary
-and secondary NVIDIA NIM keys already collapse into one family) among *all*
-discovered free routes, independent of which `--pool` was requested. This is
-new evidence, not a new decision — it is computed from the same discovery
-report the catalog already validates, and it is present whether the caller
-asked for `--pool free` or `--pool auto`.
+## Current executable contract
 
-`tests/test_contextual_orchestrator_review_policy.py` gained
-`test_build_catalog_reports_free_family_diversity` (asserts diversity of 4 for
-the existing five-provider fixture) and
-`test_build_catalog_reports_single_family_free_concentration` (a regression
-test reproducing the 2026-08-29 shape: two NVIDIA keys only, which collapse to
-one family, so diversity is 1). Full suite: 1882 passed, 1 skipped; coverage
-of the changed module remains 100% (`coverage run -m pytest tests` +
-`coverage report --include=scripts/ci/contextual_orchestrator_review_policy.py`).
+Protected-main evidence now records the actual Strix policy:
 
-`.github/workflows/strix.yml` is unchanged in this PR. It still hard-pins
-`CONTEXTUAL_ORCHESTRATOR_POOL: auto` and its `STRIX_MODEL`/`STRIX_LLM` gates
-still reject anything except `orchestrator/auto`.
+- `.github/workflows/strix.yml` accepts the contextual-orchestrator gateway and
+  restricts Strix model overrides to `orchestrator/free`;
+- `tests/test_contextual_orchestrator_review_sidecar_contract.py` asserts
+  `CONTEXTUAL_ORCHESTRATOR_POOL: free`;
+- `scripts/ci/strix_quick_gate.sh` and the required-workflow smoke contracts no
+  longer treat `orchestrator/auto` as an allowed Strix model route;
+- Noema and Required OpenCode use the same `orchestrator/free` product boundary;
+- private/internal review targets require the sidecar's ZDR policy rather than a
+  workflow-local model fallback.
 
-## What has to happen before Strix can move to `orchestrator/free`
+The five bootstrap credentials may all be supplied to contextual-orchestrator:
+`BYTEZ_API_KEY`, `NVIDIA_NIM_API_KEY`, `NVIDIA_NIM_API_KEY_SUB`,
+`OPENROUTER_API_KEY`, and `OPENAI_API_KEY`. Receiving, registering, or globally
+discovering through `OPENAI_API_KEY` is not a defect. The invariant is the
+`orchestrator/free` candidate-admission boundary: OpenAI-key-derived models are
+not eligible for free-pool candidate generation, ranking, routing, serving,
+failover, fallback, preflight, or durable free-pool persistence. The four
+free-eligible credential sources still require their explicit zero-cost,
+privacy, and capability evidence; a supplied credential does not fabricate an
+eligible model.
 
-A follow-up PR to `strix.yml` (or to
-`scripts/ci/contextual_orchestrator_review_sidecar.sh`, whichever the
-implementer finds is the correct evidence-read point) should read
-`free_family_diversity` from the sidecar's `policy-report.json` after
-discovery and select `orchestrator/free` only when it is `>= 2` — i.e. the
-discovered free catalog spans at least two independent outage domains, so one
-provider's outage cannot black out Strix's required review — and fall back to
-`orchestrator/auto` otherwise. That PR was deliberately not bundled into this
-one because `strix.yml` is a `pull_request_target` required workflow
-(`docs/pr-review-and-merge-procedure.md`'s trust-boundary note: PRs that edit
-trusted review workflows run the *base branch's* trusted scripts and can fail
-their own checks until the base branch catches up) and its `STRIX_MODEL`
-allowlist is a deliberate hardened gate, not an oversight to route around in
-the same change that adds the evidence it would depend on.
+## Admission versus routing
 
-## Audit trail
+The central review catalog is an admission boundary. It may enforce explicit
+pool, zero-cost/price evidence, credential-source, capability, and ZDR
+predicates, but it must not turn discovery into a provider quota, family quota,
+candidate-count cap, cost/provider/name ordering, synthesized priority, or
+first-come escalation preference. Every evidence-eligible route remains in the
+catalog. Downstream selection requires identified routing evidence; if that
+evidence is unavailable, the runtime fails closed.

+Admission evidence and runtime readiness are distinct. The central free-only
+catalog retains every evidence-eligible route. Startup probes those admitted
+routes concurrently, with identical per-route base/escalation semantics and
+deterministic input-order evidence, so one slow provider cannot serialize the

+removes additive startup latency. The regression uses a synchronization barrier

+probe before any one route is allowed to complete.

 **Validation.** Full suite `2407 passed, 1 skipped, 21 subtests`; `coverage` 100% on `scripts/ci`; `interrogate` 100%; all four touched/added workflow files re-parse as valid YAML; `test_opencode_workflow_shell_syntax.py` and related shell-syntax tests pass unchanged.
 
 **Residual.** This closes the specific floating-image contribution from these three central workflows; it does not by itself guarantee the organization-wide Actions queue is fully drained, since other repositories' own workflows and any remaining unpinned central workflows may still request the floating image. Worth a follow-up sweep across the rest of `.github/workflows/` and sibling-repo workflows if queuing persists after this lands.

+### 2026-09-02 Noema/OpenCode reviewer readiness false-negative regression
+
+External review on `.github#1629` demonstrated a real operational false negative:
+full evidence admission had been coupled to sequential startup probing, so a large
+set of individually slow provider routes could consume the review deadline before
+Noema/OpenCode began serving. The repair keeps evidence admission complete, starts
+per-route readiness probes concurrently with no provider preference, preserves
+input-order/source evidence, and keeps each candidate's budget escalation local.
+`tests/test_contextual_orchestrator_review_preflight_concurrency.py` is the durable
+barrier-based regression: the old sequential implementation cannot pass it, while
+the GREEN implementation proves all admitted routes can enter transport before any
+route completes. Explicit legacy `--limit`/`--account-cap` CLI configuration now
+emits diagnostics while remaining decision-inert. The pinned contextual-orchestrator
+ranking contract was also re-audited: `_static_rank_key` ends in `agent.id`, so equal
+neutral priorities do not inherit discovery/list order as a routing tiebreak.

-    non-2xx, or empty content matching neither signature) is not retried: a
-    genuinely-down candidate never reaches the escalation path, so it cannot
-    produce a false "healthy" read.
-    An exception on the escalated attempt (transport failure, auth failure,
-    rate limit, server error, or a genuine budget rejection) is recorded via
-    ``_record_provider_exception`` -- the SAME sanitized classification the
-    base probe uses, regardless of attempt. An HTTP status alone does not
-    distinguish "this candidate's real ceiling is below the escalated
-    budget" from any other cause (401/429/5xx are not budget evidence); this
-    codebase has no validated signal today that does, so it does not invent
-    one via an over-specific label.
-
-    The report deliberately records only stable route identity, a bounded
-    exception class name, an optional numeric HTTP status, attempt count, and
-    a bounded ``finish_reason``. Provider response bodies, exception
-    messages, URLs, prompts, and credentials are never copied into evidence.
-    ``finish_reason`` and ``reasoning_without_content`` are populated on
-    every response-bearing outcome -- success included, not just
-    failure/escalation, so future tuning has a real "normal" baseline to
-    compare against -- and always describe the same, most recent attempt for
-    a route (the base attempt when only one was made; the escalated attempt
-    when a second was made) -- never a mix of the two attempts' state. When
-    the escalated attempt raises an exception instead of returning a
-    response, both fields are absent entirely (there is no response to
-    describe) rather than silently retaining the base attempt's values.
+    """Probe admitted routes concurrently and report evidence in catalog order.
+
+    Admission and readiness are separate contracts. Every evidence-eligible
+    route stays admitted; this stage only establishes immediate serving

+    one slow route cannot serialize startup behind every other provider. A
+    route receives one larger-budget retry only when its own response carries
+    the explicit budget-starvation signature. There is no shared first-come
+    quota, route cap, provider preference, or completion-order authority.
+
+    Results are consumed in input order, preserving exact catalog/source
+    evidence even when providers complete out of order. ``ModelClient`` keeps

+# PR #1629 exact-head admission handoff
+
+The one-shot review-admission repair completed its source mutation and focused regression on the writer branch, then published commit `56cf1db7a26dfe4d9a69687796ff8d31f0457270`. That commit removes the temporary repair workflow, trigger, and driver after changing review startup from serial full-catalog preflight to concurrent per-route readiness probing while preserving catalog-order evidence and route-local budget escalation. It also updates the ADR and product-technical gap baseline.
+
+The source publication used the repository-scoped Actions token only because the workflow-starting `PR_REVIEW_MERGE_TOKEN` and `OPENCODE_APPROVE_TOKEN` secrets were unavailable. A token-authored push is not accepted as successor-head admission evidence because GitHub suppresses normal workflow chaining in that case. This repository-owner trace commit intentionally creates a distinct non-Actions head after re-fetching the exact writer branch so the ordinary protected pull-request workflows and reviewers can evaluate the repaired source without transferring evidence from the bot-authored predecessor.
+
+Do not treat either the one-shot job or predecessor-head checks as merge evidence for this new head. Merge eligibility requires the unchanged current head to satisfy the repository's ordinary current-head checks/reviews and remain free of substantive findings.

 # PR #1629 exact-head admission handoff
 
-The one-shot review-admission repair completed its source mutation and focused regression on the writer branch, then published commit `56cf1db7a26dfe4d9a69687796ff8d31f0457270`. That commit removes the temporary repair workflow, trigger, and driver after changing review startup from serial full-catalog preflight to concurrent per-route readiness probing while preserving catalog-order evidence and route-local budget escalation. It also updates the ADR and product-technical gap baseline.

-The source publication used the repository-scoped Actions token only because the workflow-starting `PR_REVIEW_MERGE_TOKEN` and `OPENCODE_APPROVE_TOKEN` secrets were unavailable. A token-authored push is not accepted as successor-head admission evidence because GitHub suppresses normal workflow chaining in that case. This repository-owner trace commit intentionally creates a distinct non-Actions head after re-fetching the exact writer branch so the ordinary protected pull-request workflows and reviewers can evaluate the repaired source without transferring evidence from the bot-authored predecessor.
+Fresh exact-head review then identified a second startup defect: per-route fan-out allowed every model sharing one provider credential to probe simultaneously, recreating the shared-key 429 storm already recorded in the product-technical baseline. The permanent regression now distinguishes admission cardinality from transport concurrency. All evidence-eligible routes remain admitted, but preflight execution is partitioned by the same provider-account identity used by `contextual_orchestrator_review_policy.provider_account`: independent provider accounts progress concurrently, routes sharing one account are probed serially, and outcomes are restored to original catalog order before any evidence or viable-route list is emitted. This introduces no fixed route cap, rank, shared escalation quota, or completion-order authority.
 
-Do not treat either the one-shot job or predecessor-head checks as merge evidence for this new head. Merge eligibility requires the unchanged current head to satisfy the repository's ordinary current-head checks/reviews and remain free of substantive findings.

+# DeepSeek Preflight Resilience Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Keep a DeepSeek route eligible after one transient HTTP 502 and stop the review sidecar from cutting off slow reasoning-model responses at the vendored client's 90-second default.
+
+**Architecture:** Preserve contextual-orchestrator as the owner of HTTP error classification, jittered backoff, and retry behavior. The central review launcher will call `ModelClient.proxy_send()` only for idempotent preflight probes, configure exactly one transient retry, and set `timeout=None` on both preflight and serving clients; token-budget escalation remains a separate route-local semantic attempt. Provider-account lanes continue to start concurrently, and completion timing, retry count, or provider name must not become admission or routing authority.
+
+**Tech Stack:** Python 3.12, `contextual_orchestrator.orchestrator.ModelClient`, pytest, AST-based source-contract tests, GitHub Actions.
+
+**Spec:** DiagramWeave Actions run `33554858825`, job `100013111840`, step 12; contextual-orchestrator PR `#971`; central review-control PR `#1629`.
+
+## Global Constraints
+
+- The central review pool remains fail-closed `orchestrator/free`; this repair does not admit priced or unevidenced routes.
+- Retry only failures already classified transient by contextual-orchestrator; authentication, validation, malformed response, and policy errors remain terminal.
+- Preflight transport retry budget is exactly `1`; it is independent of the existing one-time output-token escalation.
+- Do not copy provider response bodies, exception messages, credentials, or prompts into persisted evidence.
+- Do not introduce route caps, provider ranking, completion-time ranking, or a shared first-come retry quota.
+- Both preflight and serving inference clients must carry `timeout=None`; workflow/job deadlines remain the outer operational cancellation boundary.
+
+---
+
+### Task 1: Pin the failing runtime contracts
+
+**Files:**
+- Create: `tests/test_contextual_orchestrator_review_transient_preflight.py`
+- Test: `tests/test_contextual_orchestrator_review_transient_preflight.py`
+
+**Interfaces:**
+- Consumes: `_preflight_review_agents(agents: list[object], *, client: Any)` from `scripts/ci/contextual_orchestrator_review_launcher.py`.
+- Produces: executable contracts proving retry-enabled preflight dispatch, terminal 401 behavior, and no inference deadline in both `ModelClient` constructors.
+
+- [ ] **Step 1: Write the failing 502 recovery test**
+
+```python
+def test_preflight_recovers_deepseek_route_after_transient_502() -> None:
+    namespace = _load_launcher()
+    agent = SimpleNamespace(
+        id="nvidia_nim_deepseek_v4_flash",
+        provider_name="nvidia_nim",
+        model="deepseek-ai/deepseek-v4-flash-0731",
+    )
+    client = _RetryingProbeClient([_http_error(502), _openai_text("OK")])
+
+    viable, report = namespace["_preflight_review_agents"]([agent], client=client)
+
+    assert viable == [agent]
+    assert client.retrying_calls == 1
+    assert client.one_shot_calls == 0
+    assert client.transport_attempts == 2
+    assert report["routes"][0]["transport_retry_budget"] == 1
+```
+
+- [ ] **Step 2: Write the terminal-error and constructor tests**
+
+```python
+def test_preflight_does_not_retry_permanent_auth_failure() -> None:
+    namespace = _load_launcher()
+    client = _RetryingProbeClient([_http_error(401)])
+    with pytest.raises(namespace["ReviewPreflightError"]) as excinfo:
+        namespace["_preflight_review_agents"]([_agent()], client=client)
+    assert client.transport_attempts == 1
+    assert excinfo.value.report["routes"][0]["http_status"] == 401
+
+
+def test_review_clients_have_no_inference_deadline_and_one_transient_retry() -> None:
+    calls = _review_model_client_calls()
+    assert len(calls) == 2
+    assert all(_kw(call, "timeout").value is None for call in calls)
+    preflight = next(call for call in calls if _kw(call, "max_retries") is not None)
+    assert isinstance(_kw(preflight, "max_retries"), ast.Name)
+    assert _kw(preflight, "max_retries").id == "REVIEW_PREFLIGHT_TRANSIENT_RETRIES"
+```
+
+- [ ] **Step 3: Run the tests and verify RED**
+
+Run: `python -m pytest -q tests/test_contextual_orchestrator_review_transient_preflight.py`
+
+Expected: FAIL because current code calls `proxy_send_once`, records a single 502 as rejected, configures `max_retries=0`, and omits `timeout=None`.
+
+### Task 2: Reuse the orchestrator retry policy and remove the inference cap
+
+**Files:**
+- Modify: `scripts/ci/contextual_orchestrator_review_launcher.py`
+- Test: `tests/test_contextual_orchestrator_review_transient_preflight.py`
+- Test: `tests/test_contextual_orchestrator_review_runtime_preflight.py`
+- Test: `tests/test_contextual_orchestrator_review_preflight_concurrency.py`
+
+**Interfaces:**
+- Consumes: `ModelClient.proxy_send(agent, endpoint, payload)` and contextual-orchestrator's existing transient classifier/backoff.
+- Produces: `_send_preflight_request(client: Any, agent: object, payload: dict[str, object]) -> object` and `REVIEW_PREFLIGHT_TRANSIENT_RETRIES = 1`.
+
+- [ ] **Step 1: Add the bounded transport contract**
+
+```python
+REVIEW_PREFLIGHT_TRANSIENT_RETRIES = 1
+
+
+def _send_preflight_request(
+    client: Any, agent: object, payload: dict[str, object]
+) -> object:
+    """Use the client's bounded transient-retry path for an idempotent probe."""
+    retrying_send = getattr(client, "proxy_send", None)
+    if callable(retrying_send):
+        return retrying_send(agent, "chat/completions", payload)
+    return client.proxy_send_once(agent, "chat/completions", payload)
+```
+
+The fallback preserves existing deterministic test doubles and compatibility clients; the real vendored `ModelClient` always takes the `proxy_send` branch.
+
+- [ ] **Step 2: Route both semantic probe attempts through the helper**
+
+Replace both base and escalated `client.proxy_send_once(...)` calls in `_preflight_review_agent` with `_send_preflight_request(...)`. Add `"transport_retry_budget": REVIEW_PREFLIGHT_TRANSIENT_RETRIES` to each route row. Keep `row["attempts"]` as the semantic prompt-attempt count so a token-budget escalation remains distinguishable from transport retries hidden inside `ModelClient`.
+
+- [ ] **Step 3: Configure the two clients**
+
+```python
+client = ModelClient(
+    timeout=None,
+    max_output_tokens=REVIEW_MAX_OUTPUT_TOKENS,
+    max_retries=REVIEW_PREFLIGHT_TRANSIENT_RETRIES,
+    temperature=REVIEW_TEMPERATURE,
+)
+```
+
+Use `timeout=None` on the serving `ModelClient` as well, without overriding its ordinary bounded retry policy.
+
+- [ ] **Step 4: Run focused GREEN verification**
+
+Run:
+
+```bash
+python -m pytest -q \
+  tests/test_contextual_orchestrator_review_transient_preflight.py \
+  tests/test_contextual_orchestrator_review_runtime_preflight.py \
+  tests/test_contextual_orchestrator_review_preflight_concurrency.py \
+  tests/test_contextual_orchestrator_review_sidecar_contract.py
+python -m compileall -q scripts/ci/contextual_orchestrator_review_launcher.py
+python -m interrogate --fail-under 100 scripts/ci/contextual_orchestrator_review_launcher.py
+```
+
+Expected: all tests and documentation coverage pass. Existing evidence order, provider-account concurrency, token escalation, secret redaction, and free-only contracts remain unchanged.
+
+### Task 3: Revalidate the protected integration path
+
+**Files:**
+- Modify: PR `ContextualWisdomLab/.github#1629` description/evidence only after the source commit exists.
+- Observe: contextual-orchestrator PR `ContextualWisdomLab/contextual-orchestrator#971`.
+- Re-run: the affected DiagramWeave review workflow after the owning fixes are available on the consumed ref.
+
+**Interfaces:**
+- Consumes: exact source head produced by Task 2 and GitHub check-runs bound to that SHA.
+- Produces: current-head test evidence and an explicit downstream revalidation requirement; no stale-head status is transferred.
+
+- [ ] **Step 1: Confirm the exact branch head and changed files**
+
+Run: `git diff --check && git status --short && git rev-parse HEAD`
+
+Expected: only the launcher, focused regression test, and this plan are publishable changes; no temporary repair workflow or driver remains.
+
+- [ ] **Step 2: Let protected checks run on the exact head**
+
+Required evidence includes the repository's normal test, security, supply-chain, and review gates. Queued or predecessor-head checks do not count as GREEN.
+
+- [ ] **Step 3: Re-run the DiagramWeave failure path**
+
+Expected runtime evidence:
+
+```text
+nvidia_nim / deepseek-v4-flash: a first transient 502 may recover inside one preflight call
+reasoning routes: no launcher-imposed 90-second inference timeout
+preflight: provider-account lanes start concurrently and evidence remains in catalog order
+```
+
+Do not claim the incident closed until an unchanged consumed head produces terminal workflow evidence.

+# Provider-Neutral Preflight Resilience Implementation Plan
+
+> **For agentic workers:** Use `superpowers:executing-plans` or `superpowers:subagent-driven-development` when continuing this plan.
+
+**Goal:** Recover any eligible model route after a bounded transient transport failure, remove implicit inference deadlines for every model, and reserve reasoning-specific handling for capability or response evidence rather than model/provider names.
+
+**Incident:** DiagramWeave Actions run `33554858825`, job `100013111840` exposed an HTTP 502 on one discovered route and a long-running review path. The observed DeepSeek/NVIDIA NIM identity is incident evidence only; it is not a policy key.
+
+**Ownership:**
+
+- `ContextualWisdomLab/contextual-orchestrator#971` owns the generic `ModelClient` transport and inference-deadline contract.
+- `ContextualWisdomLab/.github#1629` owns the central review launcher's preflight use of that contract.
+- Merged central PR `#1546` already removed fixed Noema/OpenCode/sidecar inference deadlines. This plan does not replace that work or reintroduce per-model timeout tables.
+
+## Invariants
+
+- `ModelClient.timeout=None` means no hidden wall-clock inference deadline for any model.
+- Explicit caller cancellation, stale-head cancellation, and workflow/job termination remain valid outer lifecycle controls.
+- HTTP 502, 503, 429, timeout, and connection failures are retried only when Contextual-Orchestrator classifies them as transient.
+- HTTP 400, 401, 403 and other permanent failures remain terminal under the existing taxonomy.
+- Preflight transport retry budget is exactly one recovery attempt and is recorded separately from semantic prompt attempts.
+- No branch may inspect `model`, `agent_id`, or `provider_name` to decide timeout or transport retry eligibility.
+- Reasoning-specific token escalation is triggered by response evidence: `finish_reason == "length"` or populated reasoning with no usable content. It is independent of transport retry and does not require a model-name allowlist.
+- Completion timing, retry count, provider identity, and discovery order do not become routing or admission authority.
+- Provider response bodies, prompts, exception messages, credentials, and internal topology are not persisted in preflight evidence.
+
+## Task 1: Generic transport regression
+
+**Files:**
+
+- `ContextualWisdomLab/contextual-orchestrator/tests/test_provider_gateway_resilience.py`
+- `ContextualWisdomLab/.github/tests/test_contextual_orchestrator_review_transient_preflight.py`
+
+- [x] Parameterize the HTTP 502 recovery test across `reasoning_effort_supported = None, False, True`.
+- [x] Use an arbitrary provider/model identity so the test fails if policy becomes model-name-dependent.
+- [x] Prove HTTP 401 remains single-attempt and terminal.
+- [x] Prove every review `ModelClient` constructor carries `timeout=None`, while only idempotent preflight receives the one-retry budget.
+
+## Task 2: Response-driven reasoning behavior
+
+**Files:**
+
+- `scripts/ci/contextual_orchestrator_review_launcher.py`
+- `tests/test_contextual_orchestrator_review_transient_preflight.py`
+- `tests/test_contextual_orchestrator_review_runtime_preflight.py`
+
+- [x] Keep the cheap base token budget for ordinary routes.
+- [x] Escalate the same route once when its response reports length exhaustion or reasoning without visible content.
+- [x] Add a regression using an arbitrary model name and unknown reasoning metadata; the response alone must trigger escalation from 16 to 4096 tokens.
+- [x] Keep `attempts` as semantic payload attempts and `transport_retry_budget` as transport policy evidence.
+
+## Task 3: Exact-head verification
+
+Run on each unchanged final head:
+
+```bash
+# contextual-orchestrator
+python -m pytest -q tests/test_provider_gateway_resilience.py tests/test_provider_reliability.py
+
+# central review control plane
+python -m pytest -q \
+  tests/test_contextual_orchestrator_review_transient_preflight.py \
+  tests/test_contextual_orchestrator_review_runtime_preflight.py \
+  tests/test_contextual_orchestrator_review_preflight_concurrency.py \
+  tests/test_contextual_orchestrator_review_sidecar_contract.py
+```
+
+Then require the normal repository CI, security, supply-chain and independent-review gates to reach terminal success on those exact heads. Queued, skipped, cancelled, predecessor-head or status-only results are not GREEN.
+
+After both owner changes are integrated into the refs consumed by the reusable workflow, rerun the unchanged DiagramWeave PR head. Close the incident only when the downstream Noema review produces terminal exact-head evidence.

-# DeepSeek Preflight Resilience Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Keep a DeepSeek route eligible after one transient HTTP 502 and stop the review sidecar from cutting off slow reasoning-model responses at the vendored client's 90-second default.
-
-**Architecture:** Preserve contextual-orchestrator as the owner of HTTP error classification, jittered backoff, and retry behavior. The central review launcher will call `ModelClient.proxy_send()` only for idempotent preflight probes, configure exactly one transient retry, and set `timeout=None` on both preflight and serving clients; token-budget escalation remains a separate route-local semantic attempt. Provider-account lanes continue to start concurrently, and completion timing, retry count, or provider name must not become admission or routing authority.
-
-**Tech Stack:** Python 3.12, `contextual_orchestrator.orchestrator.ModelClient`, pytest, AST-based source-contract tests, GitHub Actions.
-
-**Spec:** DiagramWeave Actions run `33554858825`, job `100013111840`, step 12; contextual-orchestrator PR `#971`; central review-control PR `#1629`.
-
-## Global Constraints
-
-- The central review pool remains fail-closed `orchestrator/free`; this repair does not admit priced or unevidenced routes.
-- Retry only failures already classified transient by contextual-orchestrator; authentication, validation, malformed response, and policy errors remain terminal.
-- Preflight transport retry budget is exactly `1`; it is independent of the existing one-time output-token escalation.
-- Do not copy provider response bodies, exception messages, credentials, or prompts into persisted evidence.
-- Do not introduce route caps, provider ranking, completion-time ranking, or a shared first-come retry quota.
-- Both preflight and serving inference clients must carry `timeout=None`; workflow/job deadlines remain the outer operational cancellation boundary.
-
----
-
-### Task 1: Pin the failing runtime contracts
-
-**Files:**
-- Create: `tests/test_contextual_orchestrator_review_transient_preflight.py`
-- Test: `tests/test_contextual_orchestrator_review_transient_preflight.py`
-
-**Interfaces:**
-- Consumes: `_preflight_review_agents(agents: list[object], *, client: Any)` from `scripts/ci/contextual_orchestrator_review_launcher.py`.
-- Produces: executable contracts proving retry-enabled preflight dispatch, terminal 401 behavior, and no inference deadline in both `ModelClient` constructors.
-
-- [ ] **Step 1: Write the failing 502 recovery test**
-
-```python
-def test_preflight_recovers_deepseek_route_after_transient_502() -> None:
-    namespace = _load_launcher()
-    agent = SimpleNamespace(
-        id="nvidia_nim_deepseek_v4_flash",
-        provider_name="nvidia_nim",
-        model="deepseek-ai/deepseek-v4-flash-0731",
-    )
-    client = _RetryingProbeClient([_http_error(502), _openai_text("OK")])
-
-    viable, report = namespace["_preflight_review_agents"]([agent], client=client)
-
-    assert viable == [agent]
-    assert client.retrying_calls == 1
-    assert client.one_shot_calls == 0
-    assert client.transport_attempts == 2
-    assert report["routes"][0]["transport_retry_budget"] == 1
-```
-
-- [ ] **Step 2: Write the terminal-error and constructor tests**
-
-```python
-def test_preflight_does_not_retry_permanent_auth_failure() -> None:
-    namespace = _load_launcher()
-    client = _RetryingProbeClient([_http_error(401)])
-    with pytest.raises(namespace["ReviewPreflightError"]) as excinfo:
-        namespace["_preflight_review_agents"]([_agent()], client=client)
-    assert client.transport_attempts == 1
-    assert excinfo.value.report["routes"][0]["http_status"] == 401
-
-
-def test_review_clients_have_no_inference_deadline_and_one_transient_retry() -> None:
-    calls = _review_model_client_calls()
-    assert len(calls) == 2
-    assert all(_kw(call, "timeout").value is None for call in calls)
-    preflight = next(call for call in calls if _kw(call, "max_retries") is not None)
-    assert isinstance(_kw(preflight, "max_retries"), ast.Name)
-    assert _kw(preflight, "max_retries").id == "REVIEW_PREFLIGHT_TRANSIENT_RETRIES"
-```
-
-- [ ] **Step 3: Run the tests and verify RED**
-
-Run: `python -m pytest -q tests/test_contextual_orchestrator_review_transient_preflight.py`
-
-Expected: FAIL because current code calls `proxy_send_once`, records a single 502 as rejected, configures `max_retries=0`, and omits `timeout=None`.
-
-### Task 2: Reuse the orchestrator retry policy and remove the inference cap
-
-**Files:**
-- Modify: `scripts/ci/contextual_orchestrator_review_launcher.py`
-- Test: `tests/test_contextual_orchestrator_review_transient_preflight.py`
-- Test: `tests/test_contextual_orchestrator_review_runtime_preflight.py`
-- Test: `tests/test_contextual_orchestrator_review_preflight_concurrency.py`
-
-**Interfaces:**
-- Consumes: `ModelClient.proxy_send(agent, endpoint, payload)` and contextual-orchestrator's existing transient classifier/backoff.
-- Produces: `_send_preflight_request(client: Any, agent: object, payload: dict[str, object]) -> object` and `REVIEW_PREFLIGHT_TRANSIENT_RETRIES = 1`.
-
-- [ ] **Step 1: Add the bounded transport contract**
-
-```python
-REVIEW_PREFLIGHT_TRANSIENT_RETRIES = 1
-
-
-def _send_preflight_request(
-    client: Any, agent: object, payload: dict[str, object]
-) -> object:
-    """Use the client's bounded transient-retry path for an idempotent probe."""
-    retrying_send = getattr(client, "proxy_send", None)
-    if callable(retrying_send):
-        return retrying_send(agent, "chat/completions", payload)
-    return client.proxy_send_once(agent, "chat/completions", payload)
-```
-
-The fallback preserves existing deterministic test doubles and compatibility clients; the real vendored `ModelClient` always takes the `proxy_send` branch.
-
-- [ ] **Step 2: Route both semantic probe attempts through the helper**
-
-Replace both base and escalated `client.proxy_send_once(...)` calls in `_preflight_review_agent` with `_send_preflight_request(...)`. Add `"transport_retry_budget": REVIEW_PREFLIGHT_TRANSIENT_RETRIES` to each route row. Keep `row["attempts"]` as the semantic prompt-attempt count so a token-budget escalation remains distinguishable from transport retries hidden inside `ModelClient`.
-
-- [ ] **Step 3: Configure the two clients**
-
-```python
-client = ModelClient(
-    timeout=None,
-    max_output_tokens=REVIEW_MAX_OUTPUT_TOKENS,
-    max_retries=REVIEW_PREFLIGHT_TRANSIENT_RETRIES,
-    temperature=REVIEW_TEMPERATURE,
-)
-```
-
-Use `timeout=None` on the serving `ModelClient` as well, without overriding its ordinary bounded retry policy.
-
-- [ ] **Step 4: Run focused GREEN verification**
-
-Run:
-
-```bash
-python -m pytest -q \
-  tests/test_contextual_orchestrator_review_transient_preflight.py \
-  tests/test_contextual_orchestrator_review_runtime_preflight.py \
-  tests/test_contextual_orchestrator_review_preflight_concurrency.py \
-  tests/test_contextual_orchestrator_review_sidecar_contract.py
-python -m compileall -q scripts/ci/contextual_orchestrator_review_launcher.py
-python -m interrogate --fail-under 100 scripts/ci/contextual_orchestrator_review_launcher.py
-```
-
-Expected: all tests and documentation coverage pass. Existing evidence order, provider-account concurrency, token escalation, secret redaction, and free-only contracts remain unchanged.
-
-### Task 3: Revalidate the protected integration path
-
-**Files:**
-- Modify: PR `ContextualWisdomLab/.github#1629` description/evidence only after the source commit exists.
-- Observe: contextual-orchestrator PR `ContextualWisdomLab/contextual-orchestrator#971`.
-- Re-run: the affected DiagramWeave review workflow after the owning fixes are available on the consumed ref.
-
-**Interfaces:**
-- Consumes: exact source head produced by Task 2 and GitHub check-runs bound to that SHA.
-- Produces: current-head test evidence and an explicit downstream revalidation requirement; no stale-head status is transferred.
-
-- [ ] **Step 1: Confirm the exact branch head and changed files**
-
-Run: `git diff --check && git status --short && git rev-parse HEAD`
-
-Expected: only the launcher, focused regression test, and this plan are publishable changes; no temporary repair workflow or driver remains.
-
-- [ ] **Step 2: Let protected checks run on the exact head**
-
-Required evidence includes the repository's normal test, security, supply-chain, and review gates. Queued or predecessor-head checks do not count as GREEN.
-
-- [ ] **Step 3: Re-run the DiagramWeave failure path**
-
-Expected runtime evidence:
-
-```text
-nvidia_nim / deepseek-v4-flash: a first transient 502 may recover inside one preflight call
-reasoning routes: no launcher-imposed 90-second inference timeout
-preflight: provider-account lanes start concurrently and evidence remains in catalog order
-```
-
-Do not claim the incident closed until an unchanged consumed head produces terminal workflow evidence.

+  The review launcher previously assigned one same-route retry to transient
+  provider failures. RFC 9110 section 9.2.2 constrains automatic replay by
+  idempotency but does not prescribe a retry count, and NIST SP 800-204 does
+  not identify a numeric retry budget for this workload. No Fugu, Conductor,
+  or TRINITY contract establishes one either. Central CI therefore configures
+  both preflight and serving `ModelClient` instances with `max_retries=0` and
+  calls the one-shot passthrough seam for preflight. Typed provider failures
+  remain audit evidence and may drive a later independently governed policy;
+  they cannot by themselves allocate another model invocation. This is
+  provider/model/capability neutral and fails closed rather than replacing the

+constructed preflight `ModelClient(max_retries=1)`. The HTTP failure taxonomy
+was evidence for *failure type*, not evidence identifying one additional model
+call. The cited RFC/NIST resilience sources do not supply that number. The
+causal owner is the central review launcher because it allocated the extra call.
+
+**Repair.** Preflight now uses `proxy_send_once`; both preflight and serving
+clients explicitly use `max_retries=0` so an older vendored orchestrator default
+cannot reintroduce an implicit retry. Failure classification is preserved in the
+sanitized route report. No provider/model/reasoning identity can change the
+transport attempt allocation. A future retry mechanism requires independently
+governed executable provenance rather than another local constant.
+
+**Verification.** `tests/test_contextual_orchestrator_no_heuristic_preflight_retry.py`
+must be RED before this repair, GREEN after it, and the one-shot source-fix
+workflow must self-remove before publication. Exact-head required workflows and

 # PR #1629 exact-head admission handoff
 
-The one-shot review-admission repair completed its source mutation and focused regression on the writer branch, then published commit `56cf1db7a26dfe4d9a69687796ff8d31f0457270`. That commit removes the temporary repair workflow, trigger, and driver after changing review startup from serial full-catalog preflight to concurrent readiness probing while preserving catalog-order evidence and route-local budget escalation. It also updates the ADR and product-technical gap baseline.
+The original one-shot review-admission repair completed its source mutation and focused regression on the writer branch, then published commit `56cf1db7a26dfe4d9a69687796ff8d31f0457270`. That earlier increment changed review startup from serial full-catalog preflight to concurrent readiness probing while preserving catalog-order evidence and route-local token-budget escalation. Fresh exact-head review then identified a second startup defect: per-route fan-out allowed every model sharing one provider credential to probe simultaneously, recreating the shared-key 429 storm already recorded in the product-technical baseline. The permanent regression now distinguishes admission cardinality from transport concurrency. All evidence-eligible routes remain admitted, but preflight execution is partitioned by the same provider-account identity used by `contextual_orchestrator_review_policy.provider_account`: independent provider accounts progress concurrently, routes sharing one account are probed serially, and outcomes are restored to original catalog order before any evidence or viable-route list is emitted. This introduces no fixed route cap, rank, shared escalation quota, or completion-order authority.
 
-Fresh exact-head review then identified a second startup defect: per-route fan-out allowed every model sharing one provider credential to probe simultaneously, recreating the shared-key 429 storm already recorded in the product-technical baseline. The permanent regression now distinguishes admission cardinality from transport concurrency. All evidence-eligible routes remain admitted, but preflight execution is partitioned by the same provider-account identity used by `contextual_orchestrator_review_policy.provider_account`: independent provider accounts progress concurrently, routes sharing one account are probed serially, and outcomes are restored to original catalog order before any evidence or viable-route list is emitted. This introduces no fixed route cap, rank, shared escalation quota, or completion-order authority.
+A later external review demonstrated a distinct authority defect: the central launcher interpreted a transient failure classification as permission to allocate one extra identical model request through `ModelClient.proxy_send()`. Failure taxonomy proves the observed kind of failure but does not establish a repository-specific numeric retry budget. The writer branch therefore now uses `proxy_send_once()` for every semantic preflight payload, omits `transport_retry_budget`, and constructs both preflight and serving `ModelClient` instances with `max_retries=0`. Response-proven token starvation may still cause one second *different* payload with the established larger token budget; that semantic escalation is not a transport replay.
 
-The source publication used the repository-scoped Actions token only because the workflow-starting `PR_REVIEW_MERGE_TOKEN` and `OPENCODE_APPROVE_TOKEN` secrets were unavailable. A token-authored push is not accepted as successor-head admission evidence because GitHub suppresses normal workflow chaining in that case. Subsequent repository-owner commits, including the provider-account concurrency regression and source repair, create distinct non-Actions heads after re-fetching the exact writer branch so the ordinary protected pull-request workflows and reviewers can evaluate the repaired source without transferring evidence from bot-authored predecessors.
+The causal production repair was applied directly on the owner branch rather than waiting on the stalled source-fix workflow. The broader regression corpus was updated in the same history: transient 502 and permanent 401 failures each prove exactly one provider send, token-starvation escalation proves exactly two distinct one-shot payloads, and both runtime ModelClient constructors prove `timeout=None` plus `max_retries=0`. The obsolete `.github/source-fix-1629-preflight-retry.trigger`, `.github/workflows/source-fix-1629-preflight-retry.yml`, and `scripts/source_fix_1629_preflight_retry.py` identities were then deleted from the candidate tree so the repair machinery cannot consume future workflow capacity or become a durable mutation mechanism.
 
-Do not treat the one-shot job, predecessor-head checks, or a review of an earlier concurrency implementation as merge evidence for the new head. Merge eligibility requires the unchanged current head to satisfy the repository's ordinary current-head checks/reviews and remain free of substantive findings.
+The earlier source publication used the repository-scoped Actions token only because workflow-starting publication credentials were unavailable. A token-authored push is not accepted as successor-head admission evidence because GitHub suppresses normal workflow chaining in that case. The current direct owner commits create ordinary pull-request successor heads and their evidence must be collected afresh. Do not transfer checks or reviews from any predecessor source-fix head.
+
+At the current integration boundary the PR remains non-mergeable against an advanced protected `main`. That integration state is independent of the one-shot transport repair and must be reconciled non-destructively; no force push, destructive rebase, self-approval, gate weakening, or stale-head evidence transfer is authorized. Merge eligibility requires an unchanged reconciled head, no temporary source-fix identity, terminal ordinary checks/reviews, and no still-valid substantive review finding.

These values\nchanged model-call quantity or test-time compute without an identified\nstatistical/research model. Issues #1454 and #1458 already documented that the\nold probe/escalation policy could not prove serving-budget compatibility and\nthat bounded escalation allocation introduced order-dependent selection.\n\n**Causal owner and repair.** The shared owner is\n`scripts/ci/contextual_orchestrator_review_launcher.py` plus\n`scripts/ci/contextual_orchestrator_review_sidecar.sh`. The repair removes\nrepository-owned generation-token, temperature, and inference-retry allocation\nfrom startup. Each admitted route receives one provider-default compatibility\nobservation; insufficient response evidence fails closed as\n`insufficient_preflight_evidence`. The virtual-pool check is likewise exactly\none provider-default request. `timeout=None` and `max_retries=0` remain explicit\nnegative controls until contextual-orchestrator's library defaults are repaired\nby their canonical owner PR.\n\n**Executable evidence.**\n`tests/test_contextual_orchestrator_review_no_heuristic_compute.py` is the\nRED-before-repair contract. Historical escalation/retry cases stay in the\nnon-collectable case module as incident evidence; the collection shim replaces\ntheir forbidden policy oracle with the fail-closed contract. Exact-head hosted\nverification is required before merge; predecessor results do not count.\n\n**Basis.** RFC 9110 constrains HTTP semantics but does not identify a number of\nLLM inference retries. Provider-published output ceilings constrain an explicit\nrequest but do not identify a desired review-generation allocation. Without an\nindependently validated compute-allocation model, fail closed is the only\nnon-invented behavior.\n'''

These values\nchanged model-call quantity or test-time compute without an identified\nstatistical/research model. Issues #1454 and #1458 already documented that the\nold probe/escalation policy could not prove serving-budget compatibility and\nthat bounded escalation allocation introduced order-dependent selection.\n\n**Causal owner and repair.** The shared owner is\n`scripts/ci/contextual_orchestrator_review_launcher.py` plus\n`contextual_orchestrator_review_sidecar.sh`. The repair removes repository-owned\ngeneration-token, temperature, and inference-retry allocation from startup.\nEach admitted route receives one provider-default compatibility observation;\ninsufficient response evidence fails closed as\n`insufficient_preflight_evidence`. The virtual-pool check is likewise one\nprovider-default request. `timeout=None` and `max_retries=0` remain explicit\nnegative controls until contextual-orchestrator's upstream defaults are repaired\nby its canonical owner PR.\n\n**Executable evidence.**\n`tests/test_contextual_orchestrator_review_no_heuristic_compute.py` is the\nRED-before-repair contract. Historical escalation/retry cases remain in the\nnon-collectable case module as incident evidence while the collection shim\nreplaces their forbidden policy oracle with the fail-closed contract. Exact-head\nhosted verification is required before merge; predecessor results do not count.\n\n**Basis.** RFC 9110 classifies HTTP semantics but does not identify a number of\nLLM inference retries. Provider-published output ceilings constrain an explicit\nrequest but do not determine a desired review-generation allocation. In the\nabsence of an independently validated compute-allocation model, the admissible\npolicy is fail closed rather than substituting another fixed number.\n'''

These values\nchanged model-call quantity or test-time compute without an identified\nstatistical/research model. Issues #1454 and #1458 already documented that the\nold probe/escalation policy could not prove serving-budget compatibility and\nthat bounded escalation allocation introduced order-dependent selection.\n\n**Causal owner and repair.** The shared owner is\n`scripts/ci/contextual_orchestrator_review_launcher.py` plus\n`scripts/ci/contextual_orchestrator_review_sidecar.sh`. The repair removes\nrepository-owned generation-token, temperature, and inference-retry allocation\nfrom startup. Each admitted route receives one provider-default compatibility\nobservation; insufficient response evidence fails closed as\n`insufficient_preflight_evidence`. The virtual-pool check is likewise exactly\none provider-default request. `timeout=None` and `max_retries=0` remain explicit\nnegative controls until contextual-orchestrator's library defaults are repaired\nby their canonical owner PR.\n\n**Executable evidence.**\n`tests/test_contextual_orchestrator_review_no_heuristic_compute.py` is the\nRED-before-repair contract. Historical escalation/retry cases stay in the\nnon-collectable case module as incident evidence; the collection shim replaces\ntheir forbidden policy oracle with the fail-closed contract. Exact-head hosted\nverification is required before merge; predecessor results do not count.\n\n**Basis.** RFC 9110 constrains HTTP semantics but does not identify a number of\nLLM inference retries. Provider-published output ceilings constrain an explicit\nrequest but do not identify a desired review-generation allocation. Without an\nindependently validated compute-allocation model, fail closed is the only\nnon-invented behavior.\n'''

 # Provider-Neutral Preflight Resilience Implementation Plan
 
-> **For agentic workers:** Use `superpowers:executing-plans` or `superpowers:subagent-driven-development` when continuing this plan.
+**Goal:** Keep central review preflight evidence-only and provider-neutral: one provider-default request per admitted route, no repository-authored token/sampling allocation, no inference retry budget, no fixed total model deadline, and concurrent progress across independently credentialed provider-account lanes.
 
-**Goal:** Recover any eligible model route after a bounded transient transport failure, remove implicit inference deadlines for every model, and reserve reasoning-specific handling for capability or response evidence rather than model/provider names.
-
-**Incident:** DiagramWeave Actions run `33554858825`, job `100013111840` exposed an HTTP 502 on one discovered route and a long-running review path. The observed DeepSeek/NVIDIA NIM identity is incident evidence only; it is not a policy key.
+**Incident history:** DiagramWeave Actions run `33554858825`, job `100013111840` exposed an HTTP 502 on one discovered route and a long-running review path. The observed DeepSeek/NVIDIA NIM identity is incident evidence only; it is not a policy key. Later organization evidence in `.github#712` showed that review-sidecar provisioning could hold hosted runner slots for hours after the protected Contextual-Orchestrator client moved to an intentionally unbounded default model timeout. That operational evidence does not justify restoring a 90-second model deadline or inventing repository-local retry/token policy.
 
 **Ownership:**
 
-- `ContextualWisdomLab/contextual-orchestrator#971` owns the generic `ModelClient` transport and inference-deadline contract.
-- `ContextualWisdomLab/.github#1629` owns the central review launcher's preflight use of that contract.
-- Merged central PR `#1546` already removed fixed Noema/OpenCode/sidecar inference deadlines. This plan does not replace that work or reintroduce per-model timeout tables.
+- `ContextualWisdomLab/contextual-orchestrator#1106` owns the generic free-pool admission, routing and test-time-compute contract; immutable released gateway/client/schema artifacts are the final shared boundary.
+- `ContextualWisdomLab/.github#1629` owns the central review launcher's temporary consumer-side admission/preflight behavior while that migration is incomplete.
+- `.github#2139/#2140` own progress/idle continuation and runner-occupancy semantics. A progress/idle control must not become a total elapsed inference deadline.
+- `.github#1150/#712` own read-only queue-health evidence and classification, not review-lane mutation.
 
 ## Invariants
 
-- `ModelClient.timeout=None` means no hidden wall-clock inference deadline for any model.
-- Explicit caller cancellation, stale-head cancellation, and workflow/job termination remain valid outer lifecycle controls.
-- Connection establishment and other transport controls are independent configuration. They are not selected from model names or reasoning capability.
-- HTTP 502, 503, 429, timeout, and connection failures are retried only when Contextual-Orchestrator classifies them as transient.
-- HTTP 400, 401, 403 and other permanent failures remain terminal under the existing taxonomy.
-- Preflight transport retry budget is exactly one recovery attempt and is recorded separately from semantic prompt attempts.
-- No branch may inspect `model`, `agent_id`, `provider_name`, or `reasoning_effort_supported` to decide inference timeout or transport retry eligibility.
-- Reasoning-specific token escalation is triggered by response evidence: `finish_reason == "length"` or populated reasoning with no usable content. It is independent of transport retry and does not require a model-name allowlist.
-- Independent provider-account lanes may probe concurrently; routes sharing one provider account remain serialized. Published results return to catalog order.
-- Completion timing, retry count, provider identity, and discovery order do not become routing or admission authority.
-- Provider response bodies, prompts, exception messages, credentials, and internal topology are not persisted in preflight evidence.
+- `ModelClient.timeout=None` means no hidden total wall-clock inference deadline for any model.
+- Explicit user cancellation, provider termination, stale-head cancellation and administrative workflow termination remain distinct lifecycle events.
+- Preflight sends one semantic provider-default request once. HTTP 502, 503, 429, timeout, connection reset and other transport outcomes remain evidence; they do not allocate another model call in the central launcher.
+- HTTP 400, 401, 403 and other permanent failures remain bounded rejection evidence under the owner taxonomy.
+- Central preflight does not author `max_tokens`, `temperature`, retry budgets, model-name allowlists or semantic token escalation. Token/sampling/TTC policy belongs to the Contextual-Orchestrator owner boundary.
+- `model`, `agent_id`, `provider_name`, `reasoning_effort_supported`, completion timing and discovery order do not decide inference deadlines or compute allocation.
+- A response containing reasoning but no usable content is rejected as observed evidence after the single provider-default request; it is not retried with a larger token budget.
+- Independent provider-account lanes may probe concurrently; routes sharing one provider account remain serialized. Published results return to catalog order, so completion timing cannot become routing preference.
+- Provider response bodies, prompts, exception messages, credentials and internal topology are not persisted in preflight evidence.
+- Queue/runner admission and repository source correctness are classified separately. A job with no runner and no executed steps is incomplete admission evidence, not source GREEN or RED.

-## Task 2: Response-driven reasoning behavior
+- [x] Prove concurrency across independent provider-account lanes while same-account routes remain serialized.
+- [x] Prove the concurrency fixture itself does not inject `max_tokens` or `temperature`.
+- [x] Require a reasoning-only/content-less response to be rejected after one provider-default request.

-- [x] Escalate the same route once when its response reports length exhaustion or reasoning without visible content.
-- [x] Add a regression using an arbitrary model name and unknown reasoning metadata; the response alone must trigger escalation from 16 to 4096 tokens.
-- [x] Keep `attempts` as semantic payload attempts and `transport_retry_budget` as transport policy evidence.
+- [x] Preserve exact `{repo, PR, head, base, workflow, run, job, runner assignment}` identity when classifying queue delay.
+- [x] Preserve current-head review work rather than cancelling it merely to free capacity.
+- [ ] Bound avoidable provisioning occupancy structurally through provider-account concurrency and progress/idle semantics, not total inference duration.
+- [ ] Demonstrate that unrelated current-head required jobs regain hosted runner admission without changing leaf `runs-on`, weakening gates or synthesizing statuses.
+- [ ] Migrate provider probing/credential/routing authority to an immutable released Contextual-Orchestrator gateway contract and remove duplicated central policy.

+Then require normal repository CI, security, supply-chain and independent-review gates to reach terminal success on that same exact head.

-After both owner changes are integrated into the refs consumed by the reusable workflow, rerun the unchanged DiagramWeave PR head. Close the incident only when the downstream Noema review produces terminal exact-head evidence.
+After the central owner repair is normally integrated and the Contextual-Orchestrator boundary is immutably released, verify an unchanged downstream review consumer.

-## Problem
+## Historical decision
 
-The review sidecar selected a fixed catalog of twelve routes and probed every one of them, then served whatever was ready. `.github#1939` made the selection diverse (round-robin across credential accounts inside each cost/ZDR tier, four routes per account), which was right, but it exposed a second defect: the per-account slice is filled from an alphabetically sorted model list, and for both NVIDIA NIM keys the first four models are `deepseek-v4-flash`, `deepseek-v4-pro`, `gemma-3-12b`, `gemma-3-4b`. NIM lists the two `gemma-3` models but answers `404` to every chat request on every run observed. Each NVIDIA key therefore served two working routes, both the most contended models, while the pre-#1939 eight-slot fill had reached `meta/llama-3.2-11b`, `llama-3.2-90b` and `meta/muse-glimmer-30b`, which were ready in every Strix artifact of that afternoon.
+This ADR proposed a repository-owned lazy-fill algorithm for review-sidecar startup. The proposal bounded candidate and probe counts, used a readiness target, retried or postponed routes after selected transport outcomes, allocated a small initial output-token budget with a larger semantic escalation, and retained an evidence-triggered priced fallback path.
 
-Measured on `ContextualWisdomLab/.github` (lane jan's census on `#1948`, verdict-step conclusions only, draft skips excluded):
+The policy was implemented in protected source while this ADR still had `Proposed` status. Subsequent organization evidence showed that the design mixed three authorities that must remain separate: provider/model routing owned by Contextual-Orchestrator, review-workflow admission owned by the central repository, and hosted-runner occupancy/reclamation owned by the workflow control plane. It also caused central CI to author model-compute policy (`max_tokens`, sampling, retry/escalation budgets) and made sidecar provisioning perform more live inference than was required to establish compatibility.
 
-| window | preflight ready of 12 | `noema-review` success / failure |
-|---|---|---|
-| before `#1939` (`main@f2f91b80`, 2026-09-05T17:25Z) | 6, 6, 5 (16:37–16:56Z artifacts) | 7 / 14 |

+The original measurements, amendments, probe-count analyses, `Retry-After` observations, and rate-limit evidence remain available in this file's Git history and in the linked issue/PR evidence (`#1948`, `#1949`, `#1957`). They remain useful incident evidence but are no longer executable policy.
 
-The evening's rate-limit pressure is a confound; the mechanism is not. A fixed slice from a list with dead entries wastes the slice, and probing every candidate regardless of how many are already ready spends per-key rate budget (`#1948`) for nothing.
+## Superseding decision
 
-## Constraints
+ADR-0003 is normative for model lifecycle and timeout semantics. For central GitHub review admission:
 
-1. No model name is hard-coded anywhere in the fill; a dead candidate is discovered by its probe, not by a list.
-2. Probe spend per sidecar boot stays bounded and is stated as a number, because the probes themselves consume the per-key budgets the served routes need (`#1948`).
-3. `#1947`'s deferral (a probed route that answered a transient status is kept behind the ready routes) applies unchanged to whatever was probed.
-4. ADR-0003's evidence-triggered priced fallback (only after every free candidate rejects) keeps its shape; the two stages still share one startup budget.
-5. `ready_count` keeps its meaning (routes proven ready by a probe) so the peers' post-merge discriminators stay comparable.
-
-## Decision
-
-The catalog is a **candidate list**, not the served set. `build_zdr_prioritized_catalog` keeps its tier-then-round-robin order (`#1939`) and is asked for up to `REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES = 24` candidates (per-account cap unchanged at 8; the sidecar's `ORCHESTRATOR_CATALOG_LIMIT` default rises from 12 to 24). `_preflight_review_agents` probes candidates **in that order and stops** as soon as `REVIEW_PREFLIGHT_TARGET_READY = 8` routes are ready or `REVIEW_PREFLIGHT_MAX_PROBES = 16` probes have been spent, whichever comes first. The auto pool's split becomes 16 free candidates and up to 8 priced fallback candidates; the production `free` pool (the sidecar default; it has no fallback stage) lists all 24. A silent candidate's probe costs up to one transport timeout (one artifact spent 805 s on 19 probes), so the probe cap bounds preflight wall time as well as request count.
-
-**Account skip.** *(The "skipped without a probe" and "two probes per account" claims in this paragraph are superseded by the 2026-09-06 amendment below: such a candidate is postponed, and the leftover budget is spent on it.)* A 429 at preflight is a per-key answer, not a per-model one. Once one credential account has answered 429 to `REVIEW_PREFLIGHT_ACCOUNT_SKIP_AFTER_429 = 2` consecutive probes, its remaining candidates are skipped without a probe and the walk continues with the other accounts' next candidates; the two probed routes are still deferred. Under the real 2026-09-06 candidate order (lane jan's table on `#1949`, rebuilt from `#1938`'s Strix artifact: both NVIDIA keys list deepseek ×2, gemma-3 ×2 (404), gemma-4-31b (empty), then the llama and muse routes; every OpenRouter free route answers 429) the plain sixteen-probe walk yields about five ready and five deferred and the readiness target is unreachable, because five probes go to an account whose every route had answered 429 in every artifact since 21:00Z and four to the dead gemma-3 entries. With the skip, the same sixteen probes reach both keys' `llama-3.2` routes and the target of eight. This is why the free pool lists 24 candidates while probing at most 16: the tail is reachable exactly when an account is skipped, and the report separates `skipped_count` from the unreached remainder (`candidate_count − probed_count − skipped_count`). A rate-limited hour therefore costs two probes per account instead of the full budget.
-
-The sidecar's job-log echo of the preflight JSON (`sed -n '1,400p'`, previously 160 lines) now fits 16 probed routes; the artifact copy was always complete.
-
-The report gains `candidate_count`, `target_ready` and `probe_budget`; `probed_count` now counts probes actually sent, and `rejected_count` is `probed − ready − deferred`. Unprobed candidates get no `routes` row.
+1. Each evidence-eligible route receives at most one provider-default semantic compatibility observation during launcher preflight.
+2. Central CI does not author `max_tokens`, `temperature`, model-name allowlists, provider/model/group preference, paid fallback, inference retry counts, semantic token escalation, or a total model wall-clock deadline.
+3. Reasoning-only, length-exhausted, malformed, transport-failed, or otherwise unusable observations are recorded as bounded rejection evidence and do not allocate another model call.
+4. Independently credentialed provider-account lanes may progress concurrently; routes sharing one account remain serialized so startup does not create a same-credential burst. Completion order does not become routing preference.
+5. The shell provisioner does not replay `/v1/chat/completions` after launcher preflight. `/healthz` plus persisted per-route evidence form the provisioning readiness boundary. The real review consumer is the first post-provisioning gateway workload.
+6. Model timeout defaults to `None`. Explicit user cancellation, provider termination, stale-head cancellation, and administrative workflow termination remain distinct lifecycle events. Progress/idle-based runner reclamation is owned separately and must not become an elapsed-time model cutoff.
+7. Provider discovery, credentials, free-pool eligibility, routing, TTC policy, and provider capability belong to the versioned Contextual-Orchestrator owner boundary. Central CI consumes that boundary and fails closed when the required capability is unavailable.
 
 ## Consequences
 
-- **Good:** a dead candidate costs one probe and yields its place to the next candidate in the same account's list; a healthy hour stops after about eight to twelve probes instead of always twelve; a bad hour is bounded at sixteen probes per stage.
-- **Cost:** in an hour where nothing is ready the sidecar sends up to 16 probes per stage where it sent 12, a third more against already exhausted keys. This is the price of finding routes past the dead ones; `#1948`'s shared rate ledger is the lever above it. The cap is also a wall-time bound: a 16-token probe can hold the full 90 s receive timeout (`#1661` run 34008191123, 04:48Z, both NVIDIA keys' deepseek-v4-pro probes at 90.06 s and 90.10 s), so a fully silent hour costs at most 16 × 90 s = 24 minutes of preflight against 18 today, and the account-skip rule cuts a rate-limited hour to two probes per account. *(That last clause is superseded by the 2026-09-06 amendment: a rate-limited hour now spends the whole probe budget rather than two probes per account.)*
-- **Unchanged:** a route that answers the probe and then goes silent at request time still costs the gateway's full retry budget (`contextual-orchestrator#1045`); readiness is measured at 16 tokens (`#1454`).
-- **Discriminator:** post-merge, `probed_count` versus `candidate_count` per boot and `ready_count` of the served set, read from the `runtime preflight summary` in the job log or the `noema-sidecar-evidence` artifact, compared with the table above.
-
-## Alternatives considered
-
-- **Raise the per-account cap back to 8 with a 12-route limit** — restores the pre-#1939 pool but reintroduces the single-account fill that `#1939` fixed; the 404s would still occupy slots.
-- **Exclude models that 404 by name** — a hard-coded exclusion list the next discovery change silently invalidates; rejected by constraint 1. The discovery-side question (why NIM lists models it does not serve) remains open in `contextual-orchestrator`.
-- **Family-level interleave inside each account's list before the cap** (jan's second layer) — would make each NVIDIA key's first six candidates span deepseek, gemma, llama, muse, minimax, mistral, but it needs a model-family equivalence derived from names, which ADR-0003/#1468 deliberately avoid; kept in reserve if the post-merge census shows same-family contention as the residual after the account skip.
-- **Probe all 24 candidates** — best served set, double the probe spend in the hour that can least afford it; rejected by constraint 2.

-## Amendment 2026-09-06: a set-aside candidate is postponed, not banned
-
-**Evidence.** Sixteen sidecar artifacts were collected on 2026-09-06 across `.github`, `argos`, `bandscope` and `naruon`; **fourteen** ran the merged rule (two, `argos` 34013128112 and `bandscope` 34013146167, still carry the pre-`#1949` report shape and are excluded). The fourteen fall into three classes, not two.
-
-| class | boots | `probed / skipped / ready` | second pass? | outcome |
-|---|---|---|---|---|
-| budget spent in the first pass | 8 | 16 / 4 / 5–6 | no — budget already gone | served; the sixth ready route (`llama-3.2-11b` on the second NVIDIA key, catalog position 17, ready in exactly these 8 artifacts) is reached **only** because four OpenRouter probes were set aside — the benefit the rule was designed for |
-| candidates exhausted, budget left | 1 | 12 / 12 / 3 (`argos` 34014143870, 06:56Z) | **yes**, up to 4 probes | served with 5 deferred, but the target of 8 was unmet with 4 probes unspent |
-| every account set aside | 5 | 6 / 18 / 0 (`rejected 6`, all 429) | **yes**, up to 10 probes | preflight failed closed |
-
-So the change is not confined to bursts: one served, ordinary-minute boot also ends its first pass under target with budget in hand. Only a boot that spends all sixteen probes in the first pass is untouched.
-
-The sidecar stderr of `.github` run 34016207820 shows its six probes (both NVIDIA keys' two deepseek routes, two OpenRouter routes) refused 429 between 07:49:35.111Z and 07:49:35.767Z. Because the walk is a round-robin across three accounts, "two consecutive 429s" on one account is two requests about **310 ms** apart (`nvidia_nim` at .111 and .422), not two probes a tenth of a second apart. The rule set all three accounts aside, the walk ended **with ten of its sixteen probes unspent**, and because deferral requires one ready route (`#1947`) nothing was served either. The five boots of that class span 07:24:50Z to 08:04:41Z.
-
-A refusal is not a verdict on the account. Run 34016093772 was inside its *own* preflight while that burst happened (its probes run from 07:46:21Z), and its `llama-3.2-11b` probes on the **same two NVIDIA keys** answered ready at 07:50:58.7Z and 07:50:59.0Z — 84 seconds after those keys refused 429 at 07:49:35Z. That boot ended `probed 16 / ready 5`.
-
-What is **not** measured: whether the ten unspent probes would have found a ready route *inside* the burst itself. No artifact answers it, because nothing records how long a refusal lasts — hence `retry_after_s` below. The pre-`#1949` walk failed similar windows for a different reason (`.github` runs 34006939646 / 34008191123 / 34008575125, 04:24–05:11Z: the same six 429s, then six gemma 404s, `ready 0` at `probed 12`), so the ban is not a regression this amendment invents; it is the ban meeting a 24-candidate list whose tail it can no longer reach.
-
-**Decision.** A candidate set aside by the account rule is appended to a postponed list in catalog order. Once the first pass ends with the readiness target unmet and probe budget left, the postponed candidates are probed in that order until the budget is spent; no account rule applies in that second pass. A boot that spends all sixteen probes in the first pass is unchanged; the other two classes above gain a second pass. The justification is not that the second pass rescues a burst — that is unmeasured — but that ending a walk under target with probe budget in hand is indefensible when the catalog's tail is where the ready routes live. Constraint 2 holds unchanged: at most sixteen probes per stage, and a silent second-pass probe is bounded by that count, not by a clock (ADR-0003 admits no time rule here).
-
-**Cost.** The second pass spends probes the walk used to abandon, so it lengthens the boot it rescues and the boot it does not. A refused probe costs about 120 ms. A **silent** one costs up to the full 90 s receive timeout (`#1661` run 34008191123, both NVIDIA keys' `deepseek-v4-pro` probes at 90.06 s and 90.10 s), and the postponed tail is full of them: `google/gemma-4-31b-it` answered `TimeoutError` in 15 of the 19 probes that reached it across these artifacts. The measured burst is therefore not a 1.2-second case — replaying 34016207820's catalog, its second pass would reach both `gemma-4-31b-it` entries, so about 3 minutes — and the worst case is 10 × 90 s ≈ **15 minutes** added to a boot that will still fail, taking a dead window from about 4 minutes to about 19 and holding the runner slot for it.
+The former `REVIEW_PREFLIGHT_MAX_TOTAL_ROUTES`, readiness targets, probe budgets, fixed 16→4096 token escalation, repository-authored sampling values, transient inference retry budgets, account-specific lazy-fill rules, and priced fallback behavior are retired from the central review-admission contract. They must not be restored from historical tests or documentation without a new accepted ADR and owner-boundary evidence.
 
-**The two-stage path costs more than the free pool's figure.** Whenever a stage lists no more candidates than the probe budget — which is exactly the auto split, 16 free primary and 8 priced fallback — the account rule now saves nothing there, because the second pass re-probes everything it set aside. Measured on a two-account, all-429 auto run: `origin/main` sends 8 requests (4 primary, 4 priced), this design sends 24 (16 primary, 8 priced). The priced stage spends paid credit, so it doubles from 4 probes to 8 in a rate-limited hour. That is accepted for the same reason as the free pool — the priced stage only runs after every free route rejected, and stopping it half-probed is the same defect one layer down — but it is a real, stated cost, not a side effect.
+This supersession does **not** claim that provider failures disappear or that all review jobs immediately obtain hosted runners. Queue admission and runner occupancy remain separately observable control-plane concerns. Current-head jobs with no runner and no executed steps are incomplete admission evidence, not source GREEN or RED.
 
-Two things are deliberately **not** traded away. The second pass never draws on the shared escalation budget (`REVIEW_PREFLIGHT_MAX_ESCALATIONS`, one counter for the whole run, carried into the priced stage by `#1458`): a postponed candidate that answers with the budget-too-small signature is rejected as `escalation_reserved_for_first_pass` rather than escalating, because otherwise candidates the previous design never probed would take escalations from the priced stage that had them, and a two-stage run measurably stops serving a route it used to serve.
+## Verification
 
-That competes directly with the org's 60-job ceiling work, and `#1949`'s measured benefit ("a dead window fails closed in about 4 minutes and returns the slot") is partly traded back for the chance to reach the catalog tail. It stays inside the probe budget this ADR bounds, `postponed_probed_count` plus the provisioning step's duration make the trade visible per boot, and `REVIEW_PREFLIGHT_MAX_PROBES` is the lever if the census says the exchange is bad.
+`#1629` owns the source transition and exact-head regression evidence. The acceptance path is:
 
-The report adds `postponed_probed_count`; `skipped_count` now means "postponed and never reached", and `candidate_count − probed_count − skipped_count` keeps its meaning. A refused probe additionally records `retry_after_s` when the response carried a whole-seconds `Retry-After` header (the HTTP-date form and out-of-range values record nothing). Nothing waits on that value; it exists so the next census can answer the question this amendment could not.
+- focused one-shot/provider-default preflight contracts,
+- normal repository CI/security/supply-chain gates on the same exact head,
+- independent review,
+- protected integration without bypass or force push,
+- immutable Contextual-Orchestrator release for the shared owner contract,
+- unchanged downstream-consumer evidence.
 
-**Discriminator.** `postponed_probed_count > 0` marks any boot that reached a second pass, which includes the `12 / 12 / 3` class as well as the burst class. To isolate the all-429 class, read the first `probed_count − postponed_probed_count` rows of `routes` (they are in probe order) and require every one to carry `http_status` 429. The next census asks (a) whether such boots end with `ready_count ≥ 1`, (b) what fraction of 429 rows carry `retry_after_s` and how long the refusals claim to last, (c) whether the healthy-minute figures (`ready 5–6`) are unchanged, and (d) the provisioning step's duration on those boots, so the benefit in (a) and the cost above are read from one table. If (a) is consistently 0 **and** (b) shows providers publishing a usable delay, the follow-up is to spend the second pass after that delay rather than immediately — a decision this ADR deliberately leaves to that data. `#1948`'s shared rate ledger remains the lever above all of it.
+Until those gates complete, this ADR's supersession records the intended contract but does not by itself authorize merge or release.
