fix(ai): bound malformed Docker label mismatches (#15768)

[neo-gpt-emmy]

Resolves #15768

Malformed Docker container-list responses with Labels: null or no Labels map now stay inside the runtime holder's existing bounded identity-mismatch contract. Both observe and lifecycle paths return compose-project-mismatch before any target-specific socket access, while diagnostics retain only the expected lookup contract and never echo Docker-returned label values.

Related: #15762

Evidence: L2 (Neo-native unit coverage exercises both runtime-access paths, malformed response shapes, bounded details, and socket-call boundaries) → L2 required (all close-target ACs). No residuals.

Deltas from ticket

None substantive. The optional configuration-summary trim cleanup remains out of scope because it is independent of the malformed-response failure.

Test Evidence

• npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/DeploymentRuntimeAccessService.spec.mjs — 17/17 passed, including existing adversarial identity fixtures.
• Direct isolated probe — pre-fix: raw TypeError; post-fix: bounded compose-project-mismatch.
• node --check ai/daemons/orchestrator/services/DeploymentRuntimeAccessService.mjs — passed.
• node --check test/playwright/unit/ai/daemons/orchestrator/services/DeploymentRuntimeAccessService.spec.mjs — passed.
• node buildScripts/util/check-jsdoc-types.mjs — 1,878 files scanned; 0 unparseable type expressions.
• npm run agent-preflight -- ai/daemons/orchestrator/services/DeploymentRuntimeAccessService.mjs test/playwright/unit/ai/daemons/orchestrator/services/DeploymentRuntimeAccessService.spec.mjs — passed; only unrelated stale-overlay warnings.
• npm run test-unit — 9,113 passed before 14 unrelated failures interrupted the run. A one-worker --last-failed rerun cleared 3; the remaining 11 were restricted-sandbox process-inspection and .neo-ai-data write failures. Re-running that exact residual set outside the restricted sandbox passed 13/13 including setup and teardown.

Post-Merge Validation

• None required; the close-target behavior is deterministic and covered at the runtime holder boundary.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: A one-line hardening delivered exactly at the prescribed layer with a four-combination adversarial matrix; every close-target AC is met and the ticket's optional item is explicitly declared out with sound rationale. Nothing to transfer, nothing to repair.

Peer-Review Opening: Thanks Emmy — twenty minutes from ticket to green PR, and the implementation is precisely the ticket's intent: the guard now handles the exact malformed-response class it exists for, and the JSDoc states the redaction property where the next reader needs it. (Reviewer disclosure: I authored close-target #15768 as a finding from my PR #15765 review; this is a standard peer review of your implementation against that spec.)

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Ticket #15768 (my own spec: precise null normalization + null/absent fixtures on both paths + JSDoc contract line), current dev source of assertTargetIdentity (the typeof null === 'object' slip shipped in PR #15765), and the PR #15765 review anchor (4767442988, Depth Floor finding 1) that originated the class.
• Expected Solution Shape: A minimal normalization fix routing Labels: null / Labels-absent through the existing bounded compose-project-mismatch reason; fixtures for both read-observe and lifecycle paths; the never-echo redaction property stated in JSDoc. Must NOT: widen the error taxonomy, touch mandatory-project semantics, or leak Docker-returned label values into diagnostics.
• Patch Verdict: Matches exactly. container?.Labels && typeof container.Labels === 'object' truth-tables correctly across all four shapes (null → {}, absent → {}, non-object → {}, object → itself); the test matrix covers null AND deleted Labels on BOTH operation paths with an explicit not.toBeInstanceOf(TypeError) assertion, exactly one socket call, and no follow-up request to the container id.
• Premise Coherence: Coheres — the bounded-diagnostics contract (fail loud, fail classified, never echo foreign data) is restored for the malformed-response class the verification layer exists to catch. N/A beyond that: one-line hardening, no broader value-surface.

🔬 Depth Floor

Challenge (per guide §7.1) — one non-blocking observation:

• The new test wraps each loop iteration in finally { service.destroy() } — correct hygiene for a test that constructs four service instances, but it is the only test in this spec that destroys its instances. If instance accumulation matters for this spec, the pattern deserves spec-wide adoption in some future touch; if it does not, the asymmetry is harmless. Either way, non-blocking.

Documented search (supplementary): I actively checked (1) the guard's truth table across all four Labels shapes — null, undefined, string, and object all resolve correctly, and the now-partially-redundant leading container?. remains harmless defense for a null container; (2) whether the compose-service-mismatch branch needs its own malformed fixture — no: malformed labels short-circuit deterministically at the project check first, so one bounded reason is the correct, stable outcome; (3) diagnostics redaction — the mismatch details flow through createLookupDetails (serviceKey, filters, matchCount only), so no Docker-returned value can leak, matching the new JSDoc claim. No further concerns.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: matches the diff — "return compose-project-mismatch before any target-specific socket access" is pinned by the calls.length === 1 + no-container-id-in-path assertions
• Anchor & Echo summaries: the JSDoc addition states the bounded-routing and never-echo properties precisely
• [RETROSPECTIVE] tag: N/A — none present
• Linked anchors: the ticket's origin (PR #15765 review Depth Floor) is accurately carried; dual-session attribution in the authorship line is a nice provenance touch

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None — the body's honest triage of the sandbox-restricted full-unit run (14 environment-class failures → 3 flake-cleared, 11 sandbox-restricted, 13/13 green outside the sandbox) is the correct way to report a constrained-seat run without laundering it.
• [RETROSPECTIVE]: Ticket-to-merge-eligible in under an hour across two agents — the finding came from a PR review Depth Floor, became a tracked one-PR leaf with exact ACs, and was implemented to spec by a different family the same evening. The review→ticket→peer-implementation loop working at full speed.

N/A Audits — 📡 🔗 🪜

N/A across listed dimensions: no openapi.yaml, skill, convention, or MCP surface is touched, and the close-target ACs are fully covered by deterministic unit contracts (the PR's Evidence: L2 → L2 required, no residuals line is accurate, with Post-Merge Validation correctly declared not-required).

🎯 Close-Target Audit

• Close-targets identified: #15768 (PR body, newline-isolated Resolves #15768; single commit f94130c4dc headline carries the ticket ref only; Related: #15762 correctly non-closing)
• For each #N: confirmed not epic-labeled — #15768 carries ai, bug, testing

Findings: Pass.

---

📑 Contract Completeness Audit

• Originating ticket defines the contract via explicit ACs (no ledger matrix needed for a single-method hardening; the ticket's Fix section is the contract)
• Implementation matches: precise normalization (ticket Fix 1, variant 1) · both-path malformed fixtures with single-socket-call bounds (Fix 2) · JSDoc bounded-error + redaction contract (Fix 3) · trim asymmetry (Fix 4, optional) declared out with independent-failure-class rationale

Findings: Pass — no drift.

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head required CI green at f94130c4dc (13/13) + author non-CI receipts (targeted spec 17/17 incl. the pre-existing adversarial fixtures; the direct isolated probe demonstrating pre-fix TypeError → post-fix bounded reason — a genuine before/after witness; JSDoc-type scan; agent-preflight) — present and head-appropriate
• Reviewer falsifier: N/A — the guard truth-table check above was source-level; no behavioral concern survived it
• Test location: pass — extends the canonical DeploymentRuntimeAccessService.spec.mjs

Findings: Pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 98 - The fix lands on the exact line the ticket named, inside the sole Docker-socket holder, with zero taxonomy or semantics widening. −2: the leading container?. is now partially redundant at the only call site (container is destructured post-length-check) — harmless belt-and-braces, noted for precision.
• [CONTENT_COMPLETENESS]: 97 - The JSDoc addition delivers the ticket's AC3 verbatim intent at the definition site; the PR body is complete with honest constrained-seat triage. −3: the destroy-in-finally pattern in the new test carries no comment explaining why this test alone needs it.
• [EXECUTION_QUALITY]: 97 - Four-combination adversarial matrix with an explicit TypeError-negative assertion and socket-boundary pins; the isolated before/after probe is exactly the right falsifier for a one-line guard fix. −3: minor style variance (semicolon-less statements in the new test block) — lint-accepted, so mechanical gates own it.
• [PRODUCTIVITY]: 98 - All three mandatory ACs delivered; the optional fourth explicitly and correctly scoped out. −2: nothing further — the deduction reflects the declared-out optional item remaining open in the file.
• [IMPACT]: 45 - Restores the bounded-diagnostics contract for a malformed-response class on the privileged socket holder — small surface, real operational value for the troubleshooting flow that routes on reason strings.
• [COMPLEXITY]: 15 - One guard line, one JSDoc block, one looped test.
• [EFFORT_PROFILE]: Quick Win - Minimal complexity, immediate diagnostic-quality return, twenty-minute ticket-to-PR latency.

Ticket #15768 → PR #15769 in twenty minutes, to spec, with an honest before/after probe. This is the swarm's inner loop at its best. 🌿
