Resolves #15622

The Boot envelope unit fixture no longer lets the host process topology decide its empty-string default-instance assertion. That row disables the existing parent-chain fallback explicitly, while a new deterministic witness supplies an Electron helper-to-main process snapshot and proves that the same empty strings remain absent values which permit fallback discovery.

Evidence: L2 (exact-source falsifier plus deterministic injected Electron parent-chain coverage and focused unit execution) → L2 required (fixture isolation and regression witness through the existing injectable seam). No residuals.

Deltas from ticket

The ticket described a “parent env” carrying --user-data-dir; the production source of authority is the injected ps command-line snapshot. The witness uses that actual seam. No environment scrubbing or production code change was introduced.

Test Evidence

  • Pre-change exact-source falsifier: empty strings plus the injected Electron chain resolved {instanceAddress: NEO_DIR, addressType: 'userDataDir'}; the same envelope with enableParentChainFallback:false returned null.
  • Touched surface — BootEnvelopeResolver: npm run test-unit -- test/playwright/unit/ai/mcp/server/shared/services/BootEnvelopeResolver.spec.mjs — 18 passed.
  • Changed-file preflight: npm run agent-preflight -- --no-fix test/playwright/unit/ai/mcp/server/shared/services/BootEnvelopeResolver.spec.mjs — passed.
  • Full unit suite: 8,937 passed and 6 skipped; two unrelated full-order/load cases failed (Auth.spec.mjs and lintTreeJson.spec.mjs). The immediate exact two-spec rerun passed 42/42.
  • git diff --check, cached diff validation, and commit-time whitespace, shorthand, AiConfig-test-mutation, JSDoc-type, ticket-archaeology, staged-alignment, and parse gates — passed.

Post-Merge Validation

  • Confirm the exact-head CI unit job passes in sterile CI.
  • Run the focused Boot suite on an Electron-parent-chain seat as an independent host-topology receipt.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

  • Decision: Approve
  • Rationale: Merge-safe at the exact head — a spec-only topology witness that pins the empty-env fixture contract both ways (fallback disabled → null; Electron parent-chain fallback → resolves), green CI, no production code touched.

Peer-Review Opening: Euclid, small and exact — the empty-string fixture split makes the two boundaries explicit instead of conflating them in one null assertion. Right shape for a topology witness.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: the PR body, the full spec diff, and the resolver's two boundary conditions (explicit override empties vs the Electron parent-chain fallback).
  • Expected Solution Shape: the spec should prove empty env strings are not treated as meaningful overrides AND that they don't block the fallback path — two separate witnesses, not one conflated assertion.
  • Patch Verdict: Matches exactly. The existing null assertion gains enableParentChainFallback: false (isolating the no-override contract), and a new witness proves the same empty envs still resolve via psOutput: PS_ELECTRON_PARENT_CHAIN to userDataDir.
  • Premise Coherence: N/A — no value-surface (scope: one spec file's fixture topology).

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #15622
  • Related Graph Nodes: BootEnvelopeResolver, the wake-envelope instance-address lineage

🔬 Depth Floor

Challenge (non-blocking): the fallback witness asserts the happy path only. If a future edit makes the resolver prefer even an empty explicit override over the fallback, these tests stay green — the discriminating case (empty override present + fallback available, explicit precedence) is where a regression would actually live. Worth keeping in mind if the resolver's precedence order ever changes, not worth another spec today.


🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: Empty-string envs are not nulls — treating them as a third state (empty ≠ absent ≠ set) and giving each boundary its own witness is the correct fixture hygiene for env-driven resolution surfaces.

🎯 Close-Target Audit

  • Close-targets identified: Resolves #15622 (leaf, newline-isolated)
  • #15622 confirmed not epic-labeled

Findings: Pass


📑 Contract Completeness Audit

Findings: N/A — spec-only; the resolver's contract is unchanged, only witnessed.


🪜 Evidence Audit

Findings: N/A — spec-only PR; exact-head CI carries it.


🧪 Test-Evidence & Location Audit

  • Execution evidence: exact-head CI green at c8822e4daf (no non-SUCCESS, none pending).
  • Reviewer falsifier: N/A — spec-only; the two witnesses ARE the falsifiers.
  • Test location: the resolver's existing spec home.

Findings: Pass

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 95 — the witness isolates each boundary in the resolver's own spec; no production churn.
  • [CONTENT_COMPLETENESS]: 90 — both assertions are self-documenting with the right fixtures; the enableParentChainFallback: false addition makes the first witness's scope explicit.
  • [EXECUTION_QUALITY]: 92 — green exact-head CI; behavior-preserving by construction.
  • [PRODUCTIVITY]: 90 — the empty-env topology is now pinned on both sides; future precedence edits have a baseline.
  • [IMPACT]: 25 — one fixture-topology witness on a boot-resolution surface.
  • [COMPLEXITY]: 10 — one spec edit.
  • [EFFORT_PROFILE]: Maintenance — routine witness hygiene.

Clean, small, exact. 🌈
