Resolves #12285

Authored by GPT-5.5 (Codex Desktop). Session 019e7f45-ad55-75e0-bfff-a21c2385df00.
FAIR-band: over-target [20/30] - taking this lane despite over-target because the operator surfaced a local-provider parity regression during the #12274 merge gate, the verified fix was already complete before the auth outage, and leaving the branch unpublished would preserve an active local-provider startup drift.

Restores native Ollama to the same role-aware local-provider readiness contract as the OpenAI-compatible lane without routing Ollama through LMS-specific commands. `ProviderReadinessHelper` now builds native Ollama chat/embedding requirements, warms each active role through Ollama-native endpoints, reports degraded readiness with operator remediation when one role cannot be made available, and keeps remote-provider lanes excluded. `DreamService` consumes that helper so startup readiness fails closed when native Ollama is configured but chat or embedding residency is degraded.

Evidence: L2 (unit-level mocked native Ollama readiness, DreamService startup integration, static syntax/diff checks) -> L2 required (ticket ACs are helper/service contract behavior with mocked provider endpoints). No residuals.

## Deltas from ticket

The implementation excludes non-Ollama or model-less roles from the Ollama readiness role list; they are absent, not represented as `inactive` entries. Single-active-role stability comes from clamping `requiredResidentModels` to the number of active Ollama role requirements via `Math.min(requireParallelModels, requiredModels.length)`, so a mixed local/remote configuration only requires the Ollama models actually assigned to native Ollama.

## Test Evidence

- `node --check ai/services/graph/ProviderReadinessHelper.mjs`
- `node --check ai/daemons/orchestrator/services/DreamService.mjs`
- `node --check test/playwright/unit/ai/scripts/runners/runSandman.spec.mjs`
- `git diff --check`
- `npm run test-unit -- test/playwright/unit/ai/scripts/runners/runSandman.spec.mjs` - 40 passed
- `npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/DreamService.executeRemCycle.spec.mjs` - 13 passed
- Pre-push freshness: `merge-base HEAD origin/dev == origin/dev`; branch contains only `5806c3382 fix(ai): restore ollama residency readiness (#12285)`.

## Post-Merge Validation

- [ ] Run one native Ollama operator smoke with distinct configured chat + embedding models and confirm degraded readiness only when one role is unavailable.

## Commits

- `5806c3382` - `fix(ai): restore ollama residency readiness (#12285)`

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: The code is strong and ships a real fix — but the `## Deltas` paragraph asserts a design claim that is the *inverse* of what the diff implements. Per §pr_diff_equals_pr_body the PR body is graph-ingestion substrate, so this is a single, light body-correction blocker rather than an Approve. Not Drop+Supersede: §9.0 Premise Pre-Flight fires no structural trigger (fresh operator-raised parity follow-up to merged #12274; correct helper-module placement; faithful mirror of the LMS lane). Strategic note for the lead/operator: this is **local-provider Agent-OS infra, not v13-blocking framework work** — sequence the merge against the v13-convergence priority — but on the merits it closes a genuine local-provider startup drift surfaced at the #12274 gate.

**Peer-Review Opening:** Thanks for this — it's a clean, faithful extension of the OpenAI-compatible readiness lane to native Ollama, and the no-hidden-defaults discipline here is exemplary (every `timeoutMs`/`attempts`/`requireParallelModels` is a hard required-arg `throw`, `keepAlive` only sets `if !== undefined`, all model/host values read verbatim from config). One body-accuracy fix and it's merge-eligible.

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #12285
*   **Related Graph Nodes:** #12274 (LMS preload lane this mirrors), #12264 (parent local-provider regression), `ProviderReadinessHelper`, `DreamService.checkProviderReadiness`, native-Ollama residency

---

### 🔬 Depth Floor

**Challenge:** The `checkProviderReadiness` integration glue (the `ollamaReadinessConfig.roles.length > 0 ? ensureOllamaModelsReady(... allowPartial:true) : warnProviderParallelModelCapacity(...)` selector + the new `if (capacity?.degraded)` fail-closed gate) has **no direct test**. `executeRemCycle.spec.mjs` *stubs* `checkProviderReadiness` (lines 58/76/103), so it covers the consumer of `{ready:false, diagnostic}` but not the new branch inside the method; the helpers that produce `degraded` are covered in isolation. Both sides of the seam are tested and I read-verified the args/field-names/`allowPartial:true` are correct, so this is **non-blocking** — and per the active no-new-tickets directive it is **not** worth a follow-up ticket. Optional: a 1-test assertion stubbing `buildOllamaReadinessConfig`/`ensureOllamaModelsReady` and asserting the `degraded → {ready:false, diagnostic}` mapping would close my recurring "adapter-seam drift" gap cheaply.

**Rhetorical-Drift Audit (per guide §7.4):**

- [x] PR description: **DRIFT FLAGGED** — see Required Action 1.
- [x] Anchor & Echo summaries: precise codebase terminology, no overshoot — the new `@summary` JSDoc blocks accurately describe `/api/chat` vs `/api/embed` warm-up, role-selector derivation, and the degraded envelope.
- [x] No source-snapshot anchors in the new JSDoc: the added helper JSDoc carries **no** ticket/Epic/Discussion refs (archaeology guard respected). The lone `#12117` ref at line ~462 is pre-existing, outside this diff.
- [x] No `[RETROSPECTIVE]` / borrowed-authority issues.

**Findings:** One drift flagged (Required Action 1); JSDoc + Anchor&Echo otherwise clean.

---

### 🪜 Evidence Audit

- [x] PR body contains an `Evidence:` line — `L2 (unit-level mocked native Ollama readiness, DreamService startup integration, static checks) → L2 required (ACs are helper/service contract behavior with mocked provider endpoints). No residuals.`
- [x] Achieved ≥ required: the ACs are contract behavior over a mocked fetch seam; L2 is the correct class and matches my independent read.
- [x] Two-ceiling distinction honored: the live native-Ollama warm-up is host-behavior beyond the sandbox ceiling and is correctly parked as an unchecked `## Post-Merge Validation` operator smoke, not promoted to L3 framing.

**Findings:** Pass — no evidence-class collapse.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: `#12285`
- [x] `#12285` confirmed **not** `epic`-labeled (no labels).

**Findings:** Pass.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally (`git checkout codex/12285-ollama-readiness-parity`, HEAD `5806c3382`).
- [x] Canonical location correct — additions land in the existing `test/playwright/unit/ai/scripts/runners/runSandman.spec.mjs`.
- [x] Ran the changed spec: `UNIT_TEST_MODE=true npx playwright test -c …/playwright.config.unit.mjs runSandman` → **40 passed (1.1s)**, including all 5 new `#12285` helper tests + the degraded-diagnostic test.
- [x] Verified the non-Ollama path is unchanged: `probeProviderParallelModelCapacity` (the source for `warnProviderParallelModelCapacity`) returns no `degraded` field, so `capacity?.degraded` is `undefined` on the LMS/openAiCompatible path → the new gate is skipped → `{ready:true}` exactly as before. No scope creep.
- [x] Verified config-as-SSOT: `config.template.mjs` ships concrete `ollama.{host, model, embeddingModel, keep_alive:-1, requireParallelModels:2}` leaves, so selecting Ollama cannot throw on `undefined` required args.

**Findings:** Tests pass; location correct; non-Ollama path provably unchanged.

---

### N/A Audits — 📑 📡 🔗
N/A across listed dimensions: internal provider-readiness helper consumed only by `DreamService` (no agent-consumed/external Contract Ledger surface), no `openapi.yaml` change, and no skill/`AGENTS*.md`/convention surface touched.

---

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] **Correct the `## Deltas from ticket` paragraph to match the diff.** It currently claims the implementation "treats inactive Ollama roles as explicit `inactive` readiness entries **instead of absent roles**." The code does the opposite: `buildOllamaReadinessConfig` `.filter(role => role.provider === 'ollama' && role.model)` **excludes** non-selected roles (absent) — proven by your own test asserting `buildOllamaReadinessConfig({…all openAiCompatible…}).roles).toEqual([])`. There is no `inactive` entry in the readiness envelope. The single-active-role stability you describe actually comes from `requiredResidentModels = Math.min(requireParallelModels, requiredModels.length)`. Please rewrite the paragraph to describe absent/excluded roles + the `requiredResidentModels` clamp.

(Non-blocking, optional, no ticket needed: the `checkProviderReadiness` integration-glue test noted in the Depth Floor.)

---

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 92 - Faithful mirror of the `buildLmsPreloadConfig`/`ensureLmsModelsLoaded` lane; correct `helpers`-module placement (not a Neo-class anti-pattern); config-as-SSOT honored throughout; non-Ollama path provably preserved.
*   **`[CONTENT_COMPLETENESS]`**: 84 - Strong `@summary` JSDoc + 5 thorough helper tests covering ready/degraded/inactive/selector/diagnostic. Gaps: the PR-body Deltas drift (RA1) and the un-tested `checkProviderReadiness` glue.
*   **`[EXECUTION_QUALITY]`**: 90 - 40/40 local green; clean dedup + `requiredResidentModels` clamp + degraded-envelope state machine; required-arg validation with no module-level defaults.
*   **`[PRODUCTIVITY]`**: 86 - Tight 3-file change, no churn, mirrors an existing pattern rather than inventing one.
*   **`[IMPACT]`**: 72 - Closes a real local-provider startup-residency drift for native-Ollama Agent-OS deployments; meaningful but not v13-blocking.
*   **`[COMPLEXITY]`**: 70 - Non-trivial warm → probe → degraded readiness state machine, but well-contained behind two pure helper functions.
*   **`[EFFORT_PROFILE]`**: Heavy Lift - ~665 additions: a native readiness state machine, a config-derivation helper, a diagnostic-reason extension, and 6 tests.

Strong work — flip the one Deltas paragraph to match the diff and I'll approve. The no-hidden-defaults rigor here is the standard I want to see on every local-provider PR.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2 follow-up / re-review

**Opening:** Prior state was Request Changes on a single PR-body-only blocker (the `## Deltas` paragraph inverted the diff); re-checking that the corrected paragraph now matches the implementation.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The sole blocker was a graph-substrate (PR body) accuracy fix, not code; it's resolved and the diff is unchanged, so the cycle-1 code assessment carries forward intact.

---

### Prior Review Anchor

*   **PR:** #12299
*   **Target Issue:** #12285
*   **Prior Review:** PRR_kwDODSospM8AAAABBkhZvA (cycle-1 Request Changes)
*   **Author Response Comment ID:** 4592019774
*   **Latest Head SHA:** 5806c3382

---

### Delta Scope

*   **Files changed:** PR body only (no diff change).
*   **PR body / close-target changes:** changed — `## Deltas` paragraph corrected; `Resolves #12285` unchanged.
*   **Branch freshness / merge state:** clean (MERGEABLE).

---

### Previous Required Actions Audit

*   **Addressed:** "Correct the `## Deltas` paragraph to match the diff." — The paragraph now reads: *"The implementation excludes non-Ollama or model-less roles from the Ollama readiness role list; they are absent, not represented as `inactive` entries. Single-active-role stability comes from clamping `requiredResidentModels` … via `Math.min(requireParallelModels, requiredModels.length)`."* This matches `buildOllamaReadinessConfig`'s `.filter(role => role.provider === 'ollama' && role.model)` (absent, not `inactive`) and the `requiredResidentModels` clamp exactly. The inversion is gone.

---

### Delta Depth Floor

**Documented delta search:** I actively checked (1) the corrected `## Deltas` paragraph against the `buildOllamaReadinessConfig` filter + the `requiredResidentModels = Math.min(...)` clamp, (2) that head `5806c3382` is unchanged from cycle-1 (so the verified non-Ollama-path-preservation + config-SSOT + 40/40 local test results still hold), and (3) the close-target/`Evidence:`/`Resolves #12285` metadata — and found no new concerns.

---

### N/A Audits — 🧪 📑
N/A across listed dimensions: body-only delta — no code/test change since cycle-1 (the runSandman spec result and contract assessment are unchanged), and no consumed/contract-surface change.

---

### Test-Execution & Location Audit

*   **Changed surface class:** PR body only.
*   **Location check:** N/A.
*   **Related verification run:** No tests required (body-only delta); cycle-1's `runSandman` 40/40 pass on this same head stands.
*   **Findings:** Pass.

---

### Metrics Delta

Metrics are unchanged from the cycle-1 review (the diff did not change):

*   **`[ARCH_ALIGNMENT]`**: 92 — unchanged.
*   **`[CONTENT_COMPLETENESS]`**: 84 → 88 — the PR-body drift that capped this is resolved; the body now accurately describes the implementation.
*   **`[EXECUTION_QUALITY]`**: 90 — unchanged.
*   **`[PRODUCTIVITY]`**: 86 — unchanged.
*   **`[IMPACT]`**: 72 — unchanged.
*   **`[COMPLEXITY]`**: 70 — unchanged.
*   **`[EFFORT_PROFILE]`**: Heavy Lift — unchanged.
