Resolves #15005

Closes two Fleet registry security boundaries discovered by the post-merge author-defense audit of PR #14998: credentialless creation can no longer inherit an orphaned secret left by a failed cross-file rollback, and public projections now redact anchored credential-key families without hiding benign metadata.

Evidence: L2 (failure-injection plus exact-head focused contract tests) → L2 required (local registry recovery and public projection boundaries). Residual: none.

Contract Ledger

Surface Source of authority Accepted behavior Fail-closed behavior Evidence
FleetRegistryService.defineAgent() registry row plus encrypted credential snapshot an explicit credential-bearing retry may replace an orphan and publish the row a credentialless create refuses a credential entry that has no registry owner rollback-failure regression in the canonical registry spec
public Fleet projections anchored sensitive-key classifier benign names such as credentialState, tokenBudget, commandLabel, and environmentName remain visible credential, token, secret, authorization, private-key, argv, env, and launch key families are removed recursively positive and negative projection matrix

Deltas from ticket

None substantive. The implementation follows the ticketed recovery invariant and anchored classifier shape.

Test Evidence

  • node --check ai/services/fleet/FleetRegistryService.mjs — passed.
  • git diff --check origin/dev...HEAD — passed.
  • NEO_TEST_SKIP_CI=true npm run test-unit -- test/playwright/unit/ai/FleetRegistryService.spec.mjs test/playwright/unit/ai/services/fleet/FleetRegistryService.spec.mjs — 38/38 passed after rebasing onto the merged PR #14998 head.
  • Broader Fleet registry, bridge, transport, Accounts, and configuration focused set — 108/108 passed before the clean rebase; the rebased delta is the same single security commit.

Post-Merge Validation

  • Confirm the merged-head focused Fleet registry suites remain green on dev.
  • Confirm no public Fleet response exposes the covered credential-key variants in the packaged harness path.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Two real security boundaries closed at the owning service with the recovery-authority semantics the ticket ratified — credentialless creation can never adopt a stranger's orphaned secret, and the public projection's deny-vocabulary is now anchored family classification instead of an exact list with standard-variant holes. Working, defect-free, sharply scoped.

Peer-Review Opening: Clean author-defense harvest, Euclid — auditing your own merged PR and cutting the falsifiers as an honest successor leaf is the pattern working as designed. The anchored regex earns its complexity: every claimed deny/survive pair actually splits.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #15005 (both falsifiers + the recovery invariant + the explicit over-redaction rationale for anchoring), current dev FleetRegistryService.mjs (the write-order two-store transaction, the exact PUBLIC_REDACTED_KEYS set, readCredentials/resolveCredential fail-closed idioms), the changed-file list, the #14918/#14998 credential-boundary lineage from hot session context.
  • Expected Solution Shape: (a) a pre-create orphan check in defineAgent — credentialless + credential-store-entry-without-row ⇒ named refusal that leaks no secret bytes; explicit credential ⇒ overwrite-as-recovery; (b) the deny-set replaced by segment-anchored family matching so refresh_token/client_secret/authorization/nested privateKey redact while credentialState/tokenBudget/commandLabel/environmentName survive; raw Brain-internal getDefinition stop-line untouched; tests in the canonical registry suites.
  • Patch Verdict: Matches exactly. The hoisted previousCredentials read also removes the old double-read in the credential-write path; the rollback comment is updated to state the new truth (failed rollback ⇒ the orphan guard is the recovery invariant); argv joins the launch family (a real gap in the old set).
  • Premise Coherence: Coheres — fail-closed over convenient on a credential surface, and the recovery authority is placed with the only caller that can legitimately claim it (one who HOLDS a credential to write). No value-surface beyond that.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

  • Challenge (non-blocking, follow-up-grade): the anchored classifier is a finite deny-family set — vocabularies like sshKey, passphrase, jwt, or cookie would pass the public projection if they ever enter fleet metadata. Today none of our surfaces write them, and the ticket's architectural-reality section correctly rejects substring matching (over-redaction of the benign quartet), so this is the right shape now — but if public-facing metadata ever grows arbitrary operator-authored keys, the durable answer flips to a benign-ALLOWLIST for public projections. Worth carrying as a design note on the registry, not as a change to this PR.
  • Also actively checked and cleared: Object.hasOwn safety (readCredentials NEVER returns undefined — missing/unreadable store fail-closes to Object.create(null), and the null-proto + hasOwn pairing mirrors the existing prototype-pollution-aware resolveCredential idiom, so toString-shaped ids stay safe); orphan-error hygiene (the refusal names the id, never the secret bytes); guard ordering (row-exists check fires first, so an existing agent keeps its own error and the orphan path is precisely credential-without-row); old deny-set regression (all 17 previous keys remain covered by the composed regex branches — spot-walked accesstoken/apitoken/githubtoken/pat through the new alternations); the claimed deny/survive matrix (walked the normalization + anchors for every pair in the test: refreshtoken/sessiontoken/clientsecret/authorization/privatekey match, credentialstate/tokenbudget/commandlabel/environmentname cannot — the $ anchor does the work).

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: matches the diff (both boundaries, the anchored-classifier claim, the rebase note)
  • Anchor & Echo summaries: isPublicSensitiveKey's JSDoc states the anchoring intent with the exact deny/survive examples the tests pin
  • [RETROSPECTIVE] tag: N/A in PR body
  • Linked anchors: the #14998 author-defense origin checks out; the PR-body Contract Ledger rows match the shipped behavior

Findings: Pass.


🧠 Graph Ingestion Notes

  • [KB_GAP]: None — the service's JSDoc plus the ticket carried the full review premise.
  • [TOOLING_GAP]: None — failure-injection via method stubbing with finally restoration runs clean in the canonical suites.
  • [RETROSPECTIVE]: Two reusable primitives: (1) cross-file write pairs need an explicit RECOVERY INVARIANT, not just best-effort rollback — "who has authority to resolve the orphan" is the design question, and the answer here (only an explicit credential-bearing retry) generalizes to every two-store transaction in the Brain; (2) anchored family classification is the middle path between exact deny-lists (variant holes) and substring matching (benign over-redaction).

N/A Audits — 🪜 📡 🔗

N/A across listed dimensions: the PR body's Evidence: L2 → L2 required declaration is honest (failure-injection + focused contract tests are exactly the required tier for local registry recovery and projection boundaries; residual: none claimed, none found); no OpenAPI surface touched; no new cross-skill convention introduced.


🎯 Close-Target Audit

  • Close-targets identified: Resolves #15005 (newline-isolated, PR body first line)
  • #15005 confirmed not epic-labeled (bug/ai); single branch commit, subject-convention ticket ref only, no stale magic keywords (git log origin/dev..HEAD verified)

Findings: Pass.


📑 Contract Completeness Audit

  • Contract Ledger present (PR body) over the ticket's ratified fix shape
  • Implementation matches both rows exactly: credentialless-create refuses an ownerless credential entry with a named recovery error / explicit retry replaces the orphan and publishes; the anchored classifier removes the credential/token/secret/authorization/private-key/argv/env/launch families recursively while the benign quartet survives (both directions pinned in the projection matrix)

Findings: Pass — no drift.


🧪 Test-Execution & Location Audit

  • Exact head 63cd99679d9236c7be1cef23f5e4532e6ed4041d checked out in a detached worktree
  • Canonical locations: both established registry suites (test/playwright/unit/ai/ + test/playwright/unit/ai/services/fleet/) extended in place
  • env NEO_TEST_SKIP_CI=true npm run test-unit -- test/playwright/unit/ai/FleetRegistryService.spec.mjs test/playwright/unit/ai/services/fleet/FleetRegistryService.spec.mjs --workers=138 passed at the exact head
  • node --check on the service → clean; current-head CI 10/10 SUCCESS re-verified immediately before posting

Findings: Tests pass.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 100 - Actively checked placement (both boundaries land at the owning registry service; the raw getDefinition stop-line untouched), recovery-authority semantics (the overwrite right belongs exclusively to a credential-HOLDING caller), and the anchoring-vs-substring design call; all clear.
  • [CONTENT_COMPLETENESS]: 100 - The classifier's JSDoc pins intent with the exact deny/survive examples; the rewritten rollback comment states the new invariant truthfully; the PR body is a complete fat ticket with ledger and honest evidence line.
  • [EXECUTION_QUALITY]: 100 - 38/38 at exact head; the failure-injection test walks the FULL recovery arc (crash → orphan visible Brain-internally → credentialless refused → row absent → explicit retry recovers) with stub restoration in finally; the projection matrix pins both redaction directions.
  • [PRODUCTIVITY]: 100 - Both ticket falsifiers retired with permanent regressions; no scope creep.
  • [IMPACT]: 65 - Real security boundaries on the FM product path: cross-caller secret inheritance and standard-variant credential leakage through every public projection (define/get/list/configure readback) — both now fail closed.
  • [COMPLEXITY]: 35 - One guard + one anchored regex + two test extensions; the regex demands careful family reasoning but the change surface is small.
  • [EFFORT_PROFILE]: Quick Win - Small diff, high security-value density, permanent regression coverage.

Author-defense finding its own falsifiers and closing them same-day — the loop at its best. Eligible for human merge.
