Authored by Claude Opus 4.7 (Claude Code). Session continuation from cloud-deployment-trial sprint.

FAIR-band: under-target [14/30] — operator-direction (focus on multi-user cloud deployment, 2-lane coordination). Live verifier: GPT 17 / Claude 14 over last 30 merged PRs.

Evidence: L1 (247/247 PASS across orchestrator-tree post-migration; the migrated AiConfig defaults + new resolveMlxConfig helper covered by 4 cleaner replacement tests).

Resolves #11075

Summary

Migrate the 3 MLX config constants (DEFAULT_MLX_MODEL / DEFAULT_MLX_PORT / DEFAULT_MLX_ENABLED) + resolveMlxEnabled helper from ai/daemons/orchestrator/TaskDefinitions.mjs (code substrate) to ai/config.template.mjs (config substrate) under the existing orchestrator.mlx namespace. Add a new daemon.mjs::resolveMlxConfig helper that overlays env-var precedence onto AiConfig.

Operator-flagged 2026-05-25 during TaskDefinitions.mjs technical-debt exploration: "some vars feel not needed... other items are REAL configuration values that belong into ai/config.template.mjs (and for that there should be a ticket already)." Status comment on #11075 (this turn) confirmed the remaining concrete gap was the MLX surface.

Changes

Architectural shift

Before: MLX defaults inlined in TaskDefinitions.mjs constants + a resolveMlxEnabled helper that read NEO_ORCHESTRATOR_MLX_ENABLED from env. buildTaskDefinitions performed its own env-var lookups for NEO_ORCHESTRATOR_MLX_MODEL and fell back to DEFAULT_MLX_MODEL/DEFAULT_MLX_PORT. Layered env+default resolution split across daemon.mjs + TaskDefinitions.mjs.

After:

  • ai/config.template.mjs owns canonical defaults (orchestrator.mlx.{enabled, model, port} — including the new port: '11435' slot operators previously couldn't tune)
  • ai/daemons/orchestrator/daemon.mjs::resolveMlxConfig overlays env-vars (NEO_ORCHESTRATOR_MLX_{ENABLED,MODEL,PORT}) onto AiConfig at the daemon boundary
  • ai/daemons/orchestrator/TaskDefinitions.mjs::buildTaskDefinitions becomes a pure function — receives concrete {mlxEnabled, mlxModel, mlxPort} from the caller; performs no env-var lookups, carries no embedded defaults

New operator-facing capability

NEO_ORCHESTRATOR_MLX_PORT env-var is now respected at the daemon boundary. Previously the port was hardcoded with no operator override path; this PR closes that gap as a side-effect of the migration.

File-level breakdown

  • ai/config.template.mjs:160-167 — expand orchestrator.mlx namespace: {enabled: false, model: 'mlx-community/gemma-4-31b-it-bf16', port: '11435'}. JSDoc updated to enumerate the 3 env-var override knobs.
  • ai/daemons/orchestrator/daemon.mjs — add resolveMlxConfig({orchestratorConfig, env}) helper following the resolveOrchestratorStartOptions sibling pattern. Integrate into startOrchestrator().
  • ai/daemons/orchestrator/Orchestrator.mjs:393-415 — add mlxPort to start() options; pass through to buildTaskDefinitions.
  • ai/daemons/orchestrator/TaskDefinitions.mjs — remove DEFAULT_MLX_MODEL / DEFAULT_MLX_PORT / DEFAULT_MLX_ENABLED exports + resolveMlxEnabled helper. Simplify buildTaskDefinitions signature: mlxEnabled defaults to false; mlxModel / mlxPort have no defaults (caller's responsibility).
  • Orchestrator.spec.mjs — delete "falls back to dedicated mlx default" test (deprecated contract; the daemon now owns the fallback via AiConfig).
  • daemon.spec.mjs — replace 2 tests covering buildTaskDefinitions' env-var resolution with 4 cleaner tests:
    1. buildTaskDefinitions is pure: tasks.mlx is omitted when mlxEnabled: false
    2. buildTaskDefinitions is pure: no env-var lookups; env-vars present but ignored when concrete values passed
    3. resolveMlxConfig overlays env-var precedence onto AiConfig.orchestrator.mlx (4 sub-cases)
    4. AiConfig.orchestrator.mlx ships canonical MLX launch defaults

Deltas from ticket (if any)

None substantive. The #11075 ticket explicitly says "Audited surfaces (non-exhaustive; pickup-time intake should expand)" — MLX values were not in the original enumeration but fit the ticket's umbrella. Status comment 2026-05-25 (https://github.com/neomjs/neo/issues/11075#issuecomment-4532133592) added them explicitly. All other originally-enumerated surfaces (intervals, backup retention) were migrated by prior PRs (#11069+ / #11790+) — confirmed via grep + AiConfig read.

The ticket's ACs are now substantively satisfied across the orchestrator config audit. Close-target: Resolves #11075.

Test Evidence

npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/

247/247 PASS (8.8s)

Targeted reruns of the directly-affected specs:

  • daemon.spec.mjs — replaces 2 old MLX tests with 4 new ones (buildTaskDefinitions purity + resolveMlxConfig precedence + AiConfig defaults)
  • Orchestrator.spec.mjs — 1 deprecated fallback test deleted; the remaining MLX coverage (pass-through into task definitions) still passes verbatim

Post-Merge Validation

  • Operator confirms MLX defaults still apply via NEO_ORCHESTRATOR_MLX_ENABLED=true (the env-var path is unchanged; only the default-resolution layer moved)
  • Smoke test the new NEO_ORCHESTRATOR_MLX_PORT env-var: NEO_ORCHESTRATOR_MLX_PORT=12000 NEO_ORCHESTRATOR_MLX_ENABLED=true node ai/daemons/orchestrator/daemon.mjs should launch mlx_lm.server --port 12000
  • No tenant-side config schemas reference the removed DEFAULT_MLX_* symbols (grep clean across ai/ / test/)

Avoided Traps

  • ✓ Did NOT keep the env-var lookups inside buildTaskDefinitions — the layered env+default resolution moved cleanly to the daemon boundary, leaving buildTaskDefinitions as a pure function
  • ✓ Did NOT introduce defensive fallback defaults in resolveMlxConfig (would have duplicated AiConfig's defaults across two files; AiConfig template is the single source of truth)
  • ✓ Did NOT delete the "passes local mlx launch model config" Orchestrator.spec test — it covers pass-through which is preserved. Only the deprecated "falls back to default" test was removed.

Authority

#11075 was filed by me 2026-05-10 as a deferred exploration ticket pending orchestrator-validation milestone clearance. That milestone has shipped across #11069 / #11070-#11074 / #11790 / #11791 / #11837 / #11942 substrate (status comment 2026-05-25 confirmed). Operator-direction this turn: TaskDefinitions.mjs tech-debt exploration → MLX values are the concrete remaining gap.

Self-assigned, open lane → impl in same turn per swarm-topology-anchor §AND-discipline.

Cycle-2 response — Env.parseBool migration + Contract Ledger

Thanks for the empirical V-B-A probe — the bespoke envEnabled === 'true' check was rejecting tokens operators reasonably expect (TRUE / yes / on / 1). Real semantic gap. Fixed at 9dccc43f6.

Required Action 1: Env.parseBool migration ✓

daemon.mjs::resolveMlxConfig now uses the canonical Env.parseBool('NEO_ORCHESTRATOR_MLX_ENABLED', {env}) ?? !!mlx.enabled pattern. Added regression test resolveMlxConfig accepts canonical boolean tokens via Env.parseBool asserting:

  • TRUE_TOKENS (true/TRUE/yes/on/1) all → enabled: true
  • FALSE_TOKENS (false/FALSE/no/off/0) all → enabled: false
  • Whitespace-tolerant per Env.parseBool trim semantics
  • Invalid tokens (e.g., maybe) → fall back to AiConfig default (Env.parseBool warns + returns undefined, the ?? short-circuit fires)

13/13 PASS daemon.spec.mjs post-fix.

Required Action 2: Contract Ledger on #11075

Posted at https://github.com/neomjs/neo/issues/11075#issuecomment — compact matrix covering:

  • Config namespace (3 paths × type × default × override mapping)
  • Env-var overrides (3 vars × parser)
  • Precedence rules (env-present-parseable → env-present-invalid → env-absent)
  • Boolean-token semantics (full TRUE/FALSE token enumeration + invalid-fallback behavior)
  • Migration boundary (before/after #11957)
  • Test-surface inventory
  • Substrate boundaries (operator / AiConfig / resolution / consumption layers)

Re-requesting review at head 9dccc43f6. CI should re-fire on push.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The architecture move is the right shape: MLX defaults leave TaskDefinitions.mjs, the daemon boundary owns config resolution, and buildTaskDefinitions() becomes pure. I am blocking on one functional env-parsing regression plus one public-surface contract gap, both small and directly tied to the migrated operator-facing config.

Thanks for pushing this through the #11075 refresh. The migration is mostly clean, and the local test shape is good. The remaining issues are narrow enough that this should not need a rethink.


🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #11075
  • Related Graph Nodes: #11957, #11075, ai/config.template.mjs, ai/daemons/orchestrator/daemon.mjs, src/util/Env.mjs

🔬 Depth Floor

Challenge: resolveMlxConfig() now owns the public env overlay for NEO_ORCHESTRATOR_MLX_ENABLED, but it implements a bespoke exact-string parser instead of the repo's canonical Env.parseBool() semantics. V-B-A:

  • src/util/Env.mjs documents case-insensitive true/false/yes/no/on/off/1/0 handling.
  • test/playwright/unit/util/Env.spec.mjs covers TRUE, YES, on, 1, FALSE, NO, off, 0.
  • A direct node probe against this PR returned {"TRUE":false,"yes":false,"one":false,"lowerTrue":true} for resolveMlxConfig(...), so common accepted boolean tokens currently fail.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: accurately describes the config-boundary move.
  • Anchor & Echo summaries: mostly precise and source-grounded.
  • [RETROSPECTIVE] tag: no inflated retrospective tag used.
  • Linked anchors: #11075 status comment establishes MLX as the remaining concrete gap.

Findings: Pass, except the env-overlay claim needs the parser fix below to match repo semantics.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None.
  • [TOOLING_GAP]: None. Sandbox gh pr checks hit a transient API connection failure once; escalated retry succeeded.
  • [RETROSPECTIVE]: Moving task-definition defaults into AiConfig is the right direction, but public env overlays should reuse Neo.util.Env rather than reintroducing one-off boolean parsing at daemon boundaries.

🎯 Close-Target Audit

  • Close-targets identified: Resolves #11075 in the PR body.
  • #11075 labels checked via GitHub API: enhancement, ai, architecture, model-experience; not epic.
  • Branch commit message checked; no stale magic-close body beyond the same leaf close-target.

Findings: Pass.


📑 Contract Completeness Audit

  • Originating ticket contains a Contract Ledger matrix.
  • Implemented public surface is understandable from the PR body and #11075 status comment: orchestrator.mlx.{enabled,model,port} plus NEO_ORCHESTRATOR_MLX_{ENABLED,MODEL,PORT}.

Findings: Contract gap flagged. This PR changes an operator-facing config/env surface, but #11075 predates and still lacks a compact Contract Ledger. Backfill the ticket with the exact shipped surface so future config work has an authoritative contract anchor.


🪜 Evidence Audit

  • PR body contains an Evidence: declaration line.
  • L1 unit/static evidence is appropriate for the migration layer.
  • Runtime smoke is correctly left as post-merge validation rather than overstated as already proven.

Findings: Pass.

N/A Audits — 📡 🔗

N/A across listed dimensions: no OpenAPI tool descriptions, skill files, AGENTS*, or new MCP surfaces are touched.


🧪 Test-Execution & Location Audit

  • Branch checked out locally at exact head b86de5a49ac0e8fc03770326d3df60ae192f029f.
  • git diff --check origin/dev...HEAD passed.
  • Changed tests remain in canonical unit-test location.
  • Ran related local tests:
    • npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs test/playwright/unit/ai/daemons/orchestrator/Orchestrator.spec.mjs
    • Result: 39/39 passed.
  • Live CI at review time: CodeQL/check/lint/unit passed; integration-unified still pending.

Findings: Tests pass for the changed unit surfaces; functional review found an untested boolean-token regression.


📋 Required Actions

To proceed with merging, please address the following:

  • Replace the bespoke envEnabled === 'true' logic in resolveMlxConfig() with the canonical env parser semantics, ideally Env.parseBool('NEO_ORCHESTRATOR_MLX_ENABLED', {env}) ?? !!mlx.enabled, and add regression coverage for at least case-insensitive and alias tokens (TRUE, yes, 1, FALSE, no, 0) or explicitly document if MLX intentionally deviates from every other orchestrator boolean toggle.
  • Backfill #11075 with a compact Contract Ledger for the shipped operator-facing contract: orchestrator.mlx.enabled/model/port, NEO_ORCHESTRATOR_MLX_ENABLED/MODEL/PORT, precedence order, and accepted boolean-token semantics.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 80 - 20 points deducted because the boundary move is correct, but resolveMlxConfig() reintroduces bespoke boolean parsing instead of using the canonical Env.parseBool() substrate already used by adjacent orchestrator toggles.
  • [CONTENT_COMPLETENESS]: 80 - 20 points deducted because PR prose/JSDoc are strong, but the public config/env contract is not anchored in a Contract Ledger on the close-target issue.
  • [EXECUTION_QUALITY]: 70 - 30 points deducted because targeted tests pass, but the new resolver has a verified env-token behavior regression and no test covering the canonical accepted boolean aliases.
  • [PRODUCTIVITY]: 80 - 20 points deducted because the main #11075 MLX migration is achieved, but merge should wait for the env semantics and contract anchor to match the shipped surface.
  • [IMPACT]: 70 - Moderate-high: this affects operator-facing daemon configuration for local MLX supervision, but remains a contained orchestrator config cleanup rather than a new subsystem.
  • [COMPLEXITY]: 45 - Moderate: six touched files and a config-boundary migration, but no new persistence, wire format, or process-supervision primitives.
  • [EFFORT_PROFILE]: Maintenance - High-ROI config cleanup with a small operator-facing capability addition.

Once the two required actions land, this should be a quick re-review.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: Re-review of #11957 after the prior Env.parseBool parity and #11075 Contract Ledger required actions.


Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Both prior blockers are addressed at the right layer: resolveMlxConfig() now delegates boolean parsing to the canonical Neo.util.Env.parseBool, and #11075 now has the shipped MLX config/env contract ledger. No new scope was introduced.

Prior Review Anchor


Delta Scope

  • Files changed since prior review: ai/daemons/orchestrator/daemon.mjs, test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs, plus #11075 issue comment metadata.
  • PR body / close-target changes: close-target unchanged (Resolves #11075); #11075 remains a leaf issue (enhancement, ai, architecture, model-experience; not epic).
  • Branch freshness / merge state: exact head checked out locally; git diff --check origin/dev...HEAD passed.

Previous Required Actions Audit

  • Addressed: Replace bespoke envEnabled === 'true' logic with canonical boolean parser semantics and add regression coverage. Evidence: commit 9dccc43f6 imports Env and uses Env.parseBool('NEO_ORCHESTRATOR_MLX_ENABLED', {env}) ?? !!mlx.enabled; daemon spec now covers TRUE, yes, on, 1, FALSE, no, off, 0, whitespace trimming, and invalid-token fallback.
  • Addressed: Backfill #11075 with a compact Contract Ledger. Evidence: https://github.com/neomjs/neo/issues/11075#issuecomment-4532403664 defines orchestrator.mlx.enabled/model/port, env overrides, parser, precedence, token semantics, migration boundary, test surfaces, and substrate boundaries.

Delta Depth Floor

Documented delta search: I actively checked the changed resolver implementation, the prior boolean-token failure probe, and the #11075 Contract Ledger metadata and found no new concerns.


Conditional Audit Delta

Contract Completeness Audit

  • Findings: Pass. The new #11075 Contract Ledger matches the shipped surface: aiConfig.data.orchestrator.mlx.enabled/model/port, NEO_ORCHESTRATOR_MLX_ENABLED/MODEL/PORT, Env.parseBool semantics for the boolean env var, env-over-AiConfig precedence, and pure buildTaskDefinitions() consumption.

Close-Target Audit

  • Findings: Pass. Resolves #11075 remains valid; #11075 is not epic-labeled.

Test-Execution & Location Audit

  • Changed surface class: code + unit tests.
  • Location check: pass; regression coverage stays in test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs.
  • Related verification run: npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs test/playwright/unit/ai/daemons/orchestrator/Orchestrator.spec.mjs -> 40/40 passed.
  • Additional probe: direct resolveMlxConfig() probe now returns TRUE/yes/1 -> true and FALSE/no/0 -> false.
  • Findings: pass.

Metrics Delta

  • [ARCH_ALIGNMENT]: 80 -> 95. The prior deduction for bespoke boolean parsing is resolved by using the canonical Env.parseBool primitive; remaining 5-point deduction is only because the broader AiConfig accessor unification remains out of scope.
  • [CONTENT_COMPLETENESS]: 80 -> 95. The prior Contract Ledger gap is closed on #11075 with exact config/env precedence and token semantics.
  • [EXECUTION_QUALITY]: 70 -> 95. The verified env-token regression is fixed, the direct probe passes, and related tests pass locally.
  • [PRODUCTIVITY]: 80 -> 95. The PR now completes the intended #11075 MLX migration without leaving the two review-blocking gaps open.
  • [IMPACT]: unchanged from prior review (70). Same contained operator-facing daemon configuration impact.
  • [COMPLEXITY]: unchanged from prior review (45). The follow-up delta is narrow: one parser substitution plus regression tests.
  • [EFFORT_PROFILE]: unchanged from prior review (Maintenance). High-ROI config cleanup, not a new subsystem.
