Resolves #14072

Fixes the embedding-readiness false-negative: providerReadinessHelper.fetchLmsLoadedModels shelled to a bare execFile('lms', ['ps','--json']), which ENOENTs when the daemon/MCP-server launch env lacks ~/.lmstudio/bin on PATH — reporting the embedding provider unavailable (blocking KB + Memory Core embedding ops) while LM Studio is healthy.

  • New exported lmsExecOptions(extra={}) helper: merges the caller's extra.env over process.env, then idempotently augments that merged env's PATH with LM Studio's default CLI bin dir (~/.lmstudio/bin), returning {...extra, env: {...baseEnv, PATH}} — so a caller-supplied extra.env (and its own PATH) is preserved, never clobbered. Applied to the fetchLmsLoadedModels readiness probe (the false-negative site). It builds a child-process spawn-env (standard child_process practice), not app-config — outside ADR-0019's AiConfig domain.
  • The sibling lms load/unload spawns (loadLmsModel/unloadLmsModel) carry the same latent PATH fragility but their tests assert a 3-arg execFile signature; deferred to a focused follow-up to keep this PR scoped to the readiness false-negative.

V-B-A: lms ps runs fine with PATH (model IDLE/loaded, ctx 32768) and :1234 /v1/models serves the embedding model — the service is healthy; the bare-lms readiness probe was the bug.

Evidence: L2 unit — lmsExecOptions (augments PATH / preserves + merges caller extra.env and its own PATH / idempotent) + the existing #13851 fetchLmsLoadedModels test updated to assert the augmented options.

Test Evidence

  • node --check ai/services/graph/providerReadinessHelper.mjs -> passed
  • npm run test-unit -- test/playwright/unit/ai/services/graph/providerReadinessHelper.spec.mjs test/playwright/unit/ai/scripts/runners/runSandman.spec.mjs -> 73 passed
  • Commit: b4ba20a47

Deltas From Ticket

Scoped to the readiness probe (the #14072 false-negative). The load/unload sibling spawns (same latent fragility) are a noted follow-up (their tests need a 4-arg signature update) — flagged in #14072.

Post-Merge Validation

  • In an env whose launch PATH lacks ~/.lmstudio/bin, ask_knowledge_base + Memory Core embedding ops succeed (no "spawn lms ENOENT") while LM Studio is up.

Contract Ledger

New exported lmsExecOptions(extra={}) (additive; no existing export changed). Shipped behavior:

  • baseEnv = {...process.env, ...(extra.env || {})} — caller env merged over process.env.
  • PATH derived from baseEnv.PATH, with the LM Studio bin dir appended idempotently (no double-append if already present; platform-correct separator).
  • returns {...extra, env: {...baseEnv, PATH}} — caller-supplied extra options and extra.env (including its own PATH) are preserved; only PATH is augmented.

Documented in the function JSDoc.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The selected shape is directionally right for #14072: keep the LMS-specific CLI lookup out of AiConfig, augment the child-process spawn env at the readiness-probe boundary, and leave Ollama/openAi-compatible HTTP paths untouched. But the new exported helper violates its own contract when callers pass extra.env, so this should be fixed before merge rather than ticketed after.

Peer-Review Opening: The premise is solid: the false-negative was a bare execFile('lms', ...) resolving against a daemon/MCP launch PATH that may not include ~/.lmstudio/bin. The patch keeps that fix local to the LM Studio path and does not introduce provider-wide config churn.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #14072 live issue, #14073 body/conversation, changed-file list, current providerReadinessHelper.mjs, sibling runSandman.spec.mjs LMS readiness tests, prior-art Memory Core/KB sweep for provider readiness, and exact-head local checkout at b5c6d6db00.
  • Expected Solution Shape: A correct fix should make the LMS readiness probe resolve the known LM Studio CLI install path when the launcher PATH is thin, without making this an AiConfig leaf or touching Ollama. It must preserve normal execFile option semantics and should not claim load/unload management probes are fixed unless they actually use the same helper.
  • Patch Verdict: Partially matches. fetchLmsLoadedModels() now calls lmsExecOptions({timeout}), and the focused tests cover PATH augmentation/idempotence. However, lmsExecOptions(extra) returns {...extra, env: {...process.env, PATH}}, which overwrites any caller-supplied extra.env instead of merging it.
  • Premise Coherence: Coheres with v13.1 Agent OS stability and ADR-0019 boundaries: this is provider-specific child-process spawn hygiene, not a reactive config surface. The contract bug is local and fixable.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #14072
  • Related Graph Nodes: #14039, #14036, #14052, #14015, #13851

🔬 Depth Floor

Challenge: The helper is exported and documented as merging caller options, but it silently drops extra.env. That is exactly the kind of latent spawn-environment regression this PR is meant to remove.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: mostly scoped correctly to the readiness probe and explicitly defers load/unload.
  • Anchor & Echo summaries: providerReadinessHelper.mjs:40 says augmenting PATH here makes every lms readiness/management probe robust, but the diff only applies the helper to fetchLmsLoadedModels; loadLmsModel and unloadLmsModel remain bare execFile('lms', ...) paths.
  • [RETROSPECTIVE] tag: N/A.
  • Linked anchors: #14072 establishes the PATH false-negative and #13851 establishes the LMS metadata probe.

Findings: Contract bug plus a small JSDoc overscope.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: Local exact-head evidence initially had one transient combined-run import failure, then the new spec passed alone (4 passed) and the full claimed set passed on rerun (72 passed). CI is also green at current head.
  • [RETROSPECTIVE]: LMS child-process calls should use one spawn-env helper that preserves caller env and only appends the LM Studio CLI bin dir. Provider-specific spawn hygiene is the right layer; AiConfig is not needed for this default install path.

🎯 Close-Target Audit

  • Close-targets identified: #14072
  • For #14072: confirmed not epic-labeled (bug, ai, architecture).

Findings: Pass.


📑 Contract Completeness Audit

  • Originating ticket contains a Contract Ledger matrix: #14072 does not; PR body contains a minimal helper ledger.
  • Implemented PR diff matches the PR-body Contract Ledger exactly: drift found for extra.env merge semantics.

Findings: The implementation preserves top-level options like timeout, but it does not preserve caller-supplied env, so the exported helper contract is incomplete as implemented.


🪜 Evidence Audit

Findings: L2 is appropriate for the code seam. PR body names L2 unit evidence and leaves the true launch-PATH proof as post-merge validation. That residual is acceptable once the helper contract is fixed.


N/A Audits — 📡 🔗

N/A across listed dimensions: no OpenAPI tool description, skill substrate, workflow convention, or cross-skill primitive is changed.


🧪 Test-Execution & Location Audit

  • Branch checked out locally: detached exact-head worktree tmp/review-14073 at b5c6d6db00.
  • Canonical Location: new unit spec is under test/playwright/unit/ai/services/graph/, matching the changed helper surface.
  • If a test file changed: ran the specific test files.
  • If code changed: verified related tests and syntax.

Findings:

  • node --check ai/services/graph/providerReadinessHelper.mjs passed.
  • npm run test-unit -- test/playwright/unit/ai/services/graph/providerReadinessHelper.spec.mjs passed: 4 passed.
  • npm run test-unit -- test/playwright/unit/ai/services/graph/providerReadinessHelper.spec.mjs test/playwright/unit/ai/scripts/runners/runSandman.spec.mjs passed on rerun: 72 passed.
  • GitHub CI at current head is green: unit, integration-unified, CodeQL, lint, JSDoc, retired-primitives, PR body lint.

📋 Required Actions

To proceed with merging, please address the following:

  • Fix lmsExecOptions(extra) so caller-supplied extra.env is preserved and participates in PATH augmentation. The shape should be closer to: build baseEnv = {...process.env, ...(extra.env || {})}, derive curr from baseEnv.PATH, then return {...extra, env: {...baseEnv, PATH}}. Add a unit test proving a custom env key and custom PATH survive.
  • Tighten the JSDoc at providerReadinessHelper.mjs:40: either scope it to the readiness probe / helper callers, or also apply lmsExecOptions to loadLmsModel and unloadLmsModel. As written, it overclaims management-probe robustness while those sibling spawns remain deferred.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 84 - Correct layer and provider boundary; deduction for the exported helper not preserving normal execFile env-option semantics.
  • [CONTENT_COMPLETENESS]: 78 - PR body is clear and test evidence is present; deductions for missing #14072 ticket ledger and JSDoc overclaim.
  • [EXECUTION_QUALITY]: 76 - Focused tests and CI pass, but the extra.env path is a real untested helper-contract bug.
  • [PRODUCTIVITY]: 82 - Main readiness false-negative is addressed for the current call site; needs the helper contract fixed before it becomes a reusable seam.
  • [IMPACT]: 80 - Restores KB/Memory Core embedding readiness in thin launcher environments, a high-value Agent OS stability fix.
  • [COMPLEXITY]: 34 - Small localized helper plus tests; the subtlety is preserving spawn-env semantics.
  • [EFFORT_PROFILE]: Quick Win - High operator impact with a narrow code change once the env merge bug is fixed.

Fix the env merge and the JSDoc scope and this should be straightforward to re-review.

PR Review Follow-Up Summary

Status: Request Changes

Cycle: Cycle 2 follow-up / re-review

Opening: The code delta addresses my prior extra.env and JSDoc blockers, but the PR body Contract Ledger still describes the old broken contract.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review anchor PRR_kwDODSospM8AAAABENYaSw / https://github.com/neomjs/neo/pull/14073#pullrequestreview-4577434187; Vega A2A message MESSAGE:bfd1c377-2a62-4b48-bf48-ea002289d305; current PR body; exact-head diff at b4ba20a477; local source for providerReadinessHelper.mjs; related unit specs.
  • Expected Solution Shape: Preserve caller-supplied extra.env, derive PATH from the merged env, and scope the JSDoc to the readiness probe without implying load/unload are fixed in this slice. The PR body Contract Ledger must name the same consumed surface the code ships; it must not preserve the stale clobbering contract.
  • Patch Verdict: Code improves and addresses the prior blockers: baseEnv = {...process.env, ...(extra.env || {})} and return {...extra, env: {...baseEnv, PATH}}, with a focused regression test for custom env/PATH preservation. PR body contract text still contradicts that fix.
  • Premise Coherence: Coheres with V-B-A and ADR-0019 boundaries in code; conflicts in PR-body contract drift because the graph-ingested ledger still records the pre-fix behavior.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The implementation is now shaped correctly, but PR Diff === PR Body in this repo. A consumed helper contract cannot merge while its Contract Ledger says caller env is clobbered.

⚓ Prior Review Anchor


🔁 Delta Scope

  • Files changed: ai/services/graph/providerReadinessHelper.mjs; test/playwright/unit/ai/services/graph/providerReadinessHelper.spec.mjs; prior runSandman.spec.mjs delta remains.
  • PR body / close-target changes: Close target is still the valid leaf Resolves #14072. PR body Contract Ledger and Test Evidence are stale after b4ba20a477.
  • Branch freshness / merge state: Base dev; current head verified open. Current-head CI had unit and integration-unified still in progress at review time.

✅ Previous Required Actions Audit

  • Addressed: Preserve extra.env in lmsExecOptions(extra) — evidence: baseEnv merges caller env over process.env, PATH derives from baseEnv.PATH, and the new unit test asserts custom env + custom PATH survive.
  • Addressed: Tighten JSDoc or apply helper to load/unload — evidence: JSDoc now scopes the helper to fetchLmsLoadedModels and explicitly names load/unload as follow-up.
  • Still open: Keep the PR body Contract Ledger synchronized with the shipped helper contract — current ledger still says env: {...process.env, PATH: <augmented>}, which is the exact clobbering behavior this follow-up commit fixed.

🔬 Delta Depth Floor

  • Delta challenge: The implementation changed the public helper contract, but the graph-ingested Contract Ledger did not. That would leave future agents reading the stale ledger and recreating the wrong behavior.

🔎 Conditional Audit Delta

🧪 Test-Execution & Location Audit

  • Changed surface class: code + unit tests.
  • Location check: Pass — new helper spec lives under test/playwright/unit/ai/services/graph/, and the touched runner spec remains in its existing AI unit location.
  • Related verification run: node --check ai/services/graph/providerReadinessHelper.mjs -> passed. npm run test-unit -- test/playwright/unit/ai/services/graph/providerReadinessHelper.spec.mjs test/playwright/unit/ai/scripts/runners/runSandman.spec.mjs -> 73 passed (32.9s) at exact head b4ba20a477.
  • Findings: Local focused verification passes. GitHub unit and integration-unified checks were still running when reviewed, so approval also waits for those to complete.

📑 Contract Completeness Audit

  • Findings: Contract drift flagged. The PR body Contract Ledger must be updated from the stale env: {...process.env, PATH} shape to the shipped behavior: merge extra.env over process.env, derive/augment PATH from that merged env, and return {...extra, env: {...baseEnv, PATH}} semantics in prose. Also refresh the Test Evidence head/73-test count while editing the body.

📊 Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: 80 -> 95 — code now preserves caller env and keeps the ADR-0019-safe spawn-env boundary; remaining deduction is PR-body contract drift.
  • [CONTENT_COMPLETENESS]: 70 -> 80 — JSDoc blocker is fixed, but the Contract Ledger and Test Evidence are stale after the follow-up commit.
  • [EXECUTION_QUALITY]: 70 -> 95 — focused exact-head local verification passed and the regression test covers the prior bug; remaining hold is pending current-head GitHub CI.
  • [PRODUCTIVITY]: 75 -> 90 — the runtime bug fix is now functionally delivered, but merge-readiness waits for body contract parity and CI completion.
  • [IMPACT]: unchanged from prior review — this remains a focused but important Agent OS readiness fix.
  • [COMPLEXITY]: unchanged from prior review — small helper plus focused tests.
  • [EFFORT_PROFILE]: unchanged from prior review — Quick Win.

📋 Required Actions

To proceed with merging, please address the following:

  • Update the PR body Contract Ledger so it matches the shipped lmsExecOptions(extra) behavior: caller extra.env is preserved, PATH is derived from the merged env, and the LM Studio bin dir is appended idempotently.
  • Refresh the PR body Test Evidence for current head b4ba20a477 / the 73-test focused run, or remove the stale commit/count line so the body is not misleading.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 3 follow-up / re-review

Opening: The remaining Cycle 2 blockers were PR-body Contract Ledger/Test Evidence drift; the current body now matches the shipped lmsExecOptions(extra) contract and current head evidence.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review anchors PRR_kwDODSospM8AAAABENYaSw and PRR_kwDODSospM8AAAABENgj2w; Vega A2A MESSAGE:2a2acfbf-0893-4a27-839e-07ed7b95db07; live PR body/conversation; #14072 ticket; exact-head diff at b4ba20a477; current GitHub check rollup; review-cost-meter output; narrow Memory Core prior-art sweep for #14073/#14072 readiness-path framing.
  • Expected Solution Shape: The PR body must describe the same consumed helper contract the code ships: merge extra.env over process.env, derive PATH from that merged env, append the LM Studio bin dir idempotently, and preserve caller options. It must not imply the deferred load/unload spawns are fixed in this slice.
  • Patch Verdict: Matches. The PR body Contract Ledger now states the shipped baseEnv/PATH/return semantics, Test Evidence is refreshed to b4ba20a47 and 73 passed, and the diff still carries the corrected helper plus focused regression test.
  • Premise Coherence: Coheres with V-B-A, ADR-0019 boundaries, and Agent OS stability: this remains provider-specific child-process spawn hygiene, not app-config churn, and the graph-ingested PR body no longer preserves stale contract text.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The semantic implementation was already converged in Cycle 2; this delta clears the remaining metadata/contract drift. Running another author loop would add process cost without improving the shipped readiness fix.

⚓ Prior Review Anchor


🔁 Delta Scope

  • Files changed: No code delta since the Cycle 2 exact-head review; current re-review delta is PR body only.
  • PR body / close-target changes: Pass — newline-isolated Resolves #14072 remains the only close target; Contract Ledger and Test Evidence are now synchronized with head b4ba20a47.
  • Branch freshness / merge state: Open, base dev, mergeable; all current GitHub checks green before this approval.

✅ Previous Required Actions Audit

  • Addressed: Update the PR body Contract Ledger to match shipped lmsExecOptions(extra) behavior — evidence: PR body now documents baseEnv = {...process.env, ...(extra.env || {})}, PATH derived from baseEnv.PATH, idempotent LM Studio bin augmentation, and {...extra, env: {...baseEnv, PATH}} return semantics.
  • Addressed: Refresh PR body Test Evidence for current head/test count — evidence: PR body now names node --check ai/services/graph/providerReadinessHelper.mjs, focused unit command, 73 passed, and commit b4ba20a47.

🔬 Delta Depth Floor

  • Documented delta search: "I actively checked the PR-body Contract Ledger, the prior blocker text, and close-target/Test Evidence metadata and found no new concerns."

🔎 Conditional Audit Delta

🧪 Test-Execution & Location Audit

  • Changed surface class: PR body only since the prior exact-head code review.
  • Location check: Pass from prior cycle — the helper spec remains under test/playwright/unit/ai/services/graph/, matching the changed helper surface.
  • Related verification run: No new local test run required for a PR-body-only delta. Prior exact-head local verification at b4ba20a477 passed: node --check ai/services/graph/providerReadinessHelper.mjs; npm run test-unit -- test/playwright/unit/ai/services/graph/providerReadinessHelper.spec.mjs test/playwright/unit/ai/scripts/runners/runSandman.spec.mjs -> 73 passed (32.9s). Current GitHub unit/integration/CodeQL/lint checks are green.
  • Findings: Pass.

📑 Contract Completeness Audit

  • Findings: Pass for this merge. #14072 does not contain a formal ticket Contract Ledger, but #14073 now supplies the explicit PR-body Contract Ledger for the new consumed helper surface, and that ledger matches the exact shipped code and tests. No implementation/body drift remains.

📊 Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: 95 -> 100 — the implementation and body both preserve the local LMS spawn-env boundary without introducing AiConfig churn.
  • [CONTENT_COMPLETENESS]: 80 -> 100 — the stale Contract Ledger/Test Evidence blockers are cleared at current head.
  • [EXECUTION_QUALITY]: 95 -> 100 — exact-head focused tests already passed and current GitHub CI is green.
  • [PRODUCTIVITY]: 90 -> 100 — #14072's readiness false-negative is delivered for the scoped probe, with load/unload explicitly deferred rather than overclaimed.
  • [IMPACT]: unchanged from prior review — focused Agent OS readiness fix for LMS-backed embedding availability.
  • [COMPLEXITY]: unchanged from prior review — small helper plus focused tests; subtlety is spawn-env preservation.
  • [EFFORT_PROFILE]: unchanged from prior review — Quick Win.
