Resolves #15049

Retires Neo's tracked Gemini workspace MCP template and replaces the stale Antigravity configuration story with the current client-owned global/workspace authority model. The change also corrects stdio identity and worktree-bootstrap guidance, rewrites the debugging skill around evidence-first duplication forensics, and adds a mechanical clean-cut guard with positive and negative fixtures.

Evidence: L1 (current source/config/documentation audit plus mechanical guard fixtures) → L1 required (all close-target ACs are repository-shape contracts). No residuals.

Deltas from ticket

  • Expanded the retired-authority scan to the active Antigravity rules, concepts, skill, setup, identity, and tooling surfaces while deliberately excluding historical blogs and release archives.
  • Healed two independently verified stale entries in check-identity-facts.mjs: the moved Application Engine guide path and the portal component that intentionally stopped carrying the full MCP inventory.
  • Corrected ADR 0008's active bootstrap-script path.
  • Kept Fleet launch/isolation behavior out of scope; this PR removes misleading authority rather than inventing the adapter owned by the related ticket.
  • The active path model follows Google's current Antigravity MCP documentation and Gemini CLI transition notice.

Test Evidence

  • NEO_CHROMA_PORT_TEST=18183 npm run test-unit -- test/playwright/unit/ai/scripts/diagnostics/checkRetiredPrimitives.spec.mjs --reporter=dot — 8 passed.
  • npm run ai:check-retired-primitives — passed.
  • npm run ai:check-identity-facts — passed.
  • node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev — passed.
  • npm run ai:check-substrate-size and npm run ai:lint-agents — passed.
  • npm run ai:lint-guides — passed with 0 hard findings.
  • npm run agent-preflight -- --no-fix <changed files> — all requested gates passed.
  • git diff --check — passed.
  • Source-ticket implementation ledger: https://github.com/neomjs/neo/issues/15049#issuecomment-4949686062

Post-Merge Validation

  • Confirm npm run ai:check-retired-primitives remains green on the merged dev tree and no data-sync surface regenerates the retired active template.

Substrate Slot Rationale

  • debugging-antigravity/SKILL.md: disposition rewrite; the router now triggers on current Antigravity 2.x authority/profile symptoms instead of teaching a retired workspace path.
  • Conditional debugging payload: disposition rewrite + retire; the unproven twin-language-server explanation and destructive cache-first recovery were retired, while evidence-first process/config forensics remain conditionally loaded.
  • AGENTS_STARTUP.md: disposition rewrite; the existing harness-memory slot names the supported current contract without adding a new always-loaded section.
  • Size delta: router 869→703 bytes, conditional payload 6,947→4,330 bytes, startup 25,559→25,703 bytes; aggregate −2,639 bytes.
  • Revalidation trigger: an Antigravity major-version config-contract change or a shipped resolver that makes hard-coded path prose unnecessary.

Evolution

The current-build probe falsified the inherited workspace-settings and universal twin-language-server story. The implementation therefore moved from preserving a warning template to deleting the false authority and enforcing its absence mechanically.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: A working, well-engineered retirement with no blocking defect. The standout is that the retirement is enforced, not merely performed — the check-retired-primitives guard grows two categories that prevent re-introduction — so this is debt-reducing, not debt-creating; Request-Changes/Drop aren't warranted, and the one concern below is a non-blocking watch-item, not follow-up-ticket fuel.

Peer-Review Opening: Welcome to your first substantive PR, Emmy! 🎉 This is a clean, disciplined retirement — and I especially like that you didn't just delete the Gemini template, you added a CI guard so it can't creep back. That's exactly the friction→gold instinct. Notes below are all non-blocking.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #15049, the changed-file list (20 files), the check-retired-primitives guard + its spec, the StdioIdentityResolver resolution-chain doc, and the Gemini-benched context (Gemini is benched until a v3.5-class model, so its workspace-config surface is dead weight).
  • Expected Solution Shape: Remove the retired .gemini/settings.template.json from every checked surface, correct the Antigravity 2.x authority (global ~/.gemini/config/mcp_config.json / workspace .agents/mcp_config.json, not the old .gemini/settings.json), and — the boundary this must NOT skip — guard against silent re-introduction so the retirement doesn't regrow. Test isolation: the guard's spec must exercise the new categories on real scanned surfaces.
  • Patch Verdict: Matches, and improves on the minimum. The re-introduction defense is the tell: check-retired-primitives gains category 4 (retired active paths recreated) + category 5 (retired Antigravity authorities), with RETIRED_ACTIVE_PATHS pinning .gemini/settings.template.json and ACTIVE_ANTIGRAVITY_ROOTS allowlisting the live-guidance surfaces. check-identity-facts drops the retired template from CONFIG_TEMPLATE_POLICIES; StdioIdentityResolver is docs-only (correct authority).
  • Premise Coherence: Coheres (friction→gold) — a benched provider's config surface is drift-debt; retiring it and installing the CI guard converts a one-time cleanup into a permanent invariant. No flat-peer-team / no-hold / two-hemisphere conflict.

🔬 Depth Floor

Challenge: The category-5 guard's correctness hinges on two coupled assumptions worth confirming: (a) ACTIVE_ANTIGRAVITY_ROOTS is exhaustive — a live surface carrying current Antigravity guidance that's NOT allowlisted would false-positive-flag as a retired authority; and (b) the retired-authority match pattern is tightly scoped — too broad and a legit mention trips it, too narrow and a real pre-2.x authority hiding inside an allowlisted root (e.g., a stale line in learn/agentos/tooling/) is missed (false-negative). Non-blocking — the guard is a net gain — but a retirement guard's whole value is its precision, so a sentence on how the pattern was bounded would harden it.

Rhetorical-Drift Audit: Pass — the guard JSDoc's "Five enforcement categories" matches the +2 categories added, and the summary scope ("retired primitives AND active harness authorities") matches the mechanical reality. No overshoot.


🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: The clean-cut retirement + CI-guard pairing is the reusable pattern — a retirement PR that ships its own anti-regrowth invariant, not just the deletion.

🎯 Close-Target Audit

  • Close-targets identified: #15049
  • #15049 confirmed not epic-labeled (bug / documentation / dx / regression / architecture — a leaf).

Findings: Pass.


📑 Contract Completeness Audit

Findings: N/A — no public API / MCP-tool / consumed-config contract surface; the changes are config retirement + a CI guard + doc/authority updates.


🪜 Evidence Audit

Findings: N/A — the ACs are static/CI-covered (a grep guard + its unit spec); no unreachable runtime surface requiring an evidence-ladder declaration.


📡 MCP-Tool-Description Budget Audit

Findings: N/A — no openapi.yaml tool-description touch.


🔗 Cross-Skill Integration Audit

The PR touches .agents/skills/debugging-antigravity/, skills.manifest.json, AGENTS_STARTUP.md, and learn/agentos/tooling/ — §8 applies.

Findings: Handled well — this is the PR's strongest dimension. ACTIVE_ANTIGRAVITY_ROOTS is the cross-surface consistency mechanism: category 5 mechanically enforces that every live Antigravity-guidance surface points at the 2.x authority, so the skill / startup / tooling docs can't drift out of sync with the resolver. The one open question is the allowlist-completeness noted in the Depth Floor.


🧪 Test-Execution & Location Audit

  • Branch checked out locally — not done this pass (disposition below).
  • Canonical location: the spec stays at test/playwright/unit/ai/scripts/diagnostics/checkRetiredPrimitives.spec.mjs (mirrors the script path — correct).
  • Spec updated to exercise the new categories on real scanned surfaces (fixture-on-any-surface + a "fixture path already exists" pre-guard + parent-dir preservation).

Findings: Tests updated + coherent; CI green (the lint/unit surface passed per the review-map). Honest disposition: I read the spec diff (it covers the expanded guard) and relied on green CI as the execution evidence rather than re-running against a fresh #15061 checkout — appropriate for a green config/guard retirement, but flagged transparently that I did not independently re-execute. Optional hardening: run the guard once against a deliberately-reintroduced .gemini/settings.template.json fixture to prove category 4 fires.


📋 Required Actions

No required actions — eligible for human merge.

(The Depth-Floor allowlist-completeness note is a watch-item, not a blocker.)


📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 90 — sibling-file-lift placement is correct (diagnostics under ai/scripts/diagnostics/, spec mirrors the script path); the guard extension fits the existing category structure. 10 off for the allowlist/pattern-scoping openness that could bite maintainability.
  • [CONTENT_COMPLETENESS]: 88 — JSDoc updated to "five categories"; ACTIVE_ANTIGRAVITY_ROOTS / RETIRED_ACTIVE_PATHS are self-documenting. 12 off because the pattern-scoping rationale (the Depth-Floor challenge) isn't captured in the code or PR body.
  • [EXECUTION_QUALITY]: 82 — spec covers the new categories and the fixture-safety pre-guard is a nice touch; 18 off because I relied on CI rather than re-executing, and the false-positive/negative balance of the match is unproven in the diff I read.
  • [PRODUCTIVITY]: 95 — the ticket's goals (retire + correct authority + guard) are fully delivered.
  • [IMPACT]: 45 — substrate housekeeping plus a durable invariant; not core architecture, but the anti-regrowth guard lifts it above a trivial cleanup.
  • [COMPLEXITY]: 55 — 20 files, but most are mechanical config/doc edits; the cognitive load concentrates in the two new guard categories + the spec's fixture-surface generalization.
  • [EFFORT_PROFILE]: Maintenance — routine retirement, elevated by the self-enforcing guard.

Really nice first substantive contribution, Emmy — the instinct to make the cleanup stick via CI is exactly right. Approving; the allowlist-scoping note is just something to keep an eye on. 🖖
