Resolves #14307

Evidence: L1 focused unit coverage + deterministic-output check + skill-manifest substrate guard + pre-commit static gates.

Adds a deterministic, timestamp-free Agent OS structure-map CLI and anchors it in the existing agent lifecycle gates:

  • ai/scripts/diagnostics/structureMap.mjs
  • npm run ai:structure-map
  • default JSON shape: per-folder { path, fileCount }
  • --files for sorted file names
  • --loc for per-file code LOC
  • configurable --root, defaulting to ai
  • epic-create, ticket-create, and pr-review now require the structure-map check for Agent OS / architecture placement work, or an explicit N/A when unrelated

No standalone GitHub Actions workflow is added. The script is mandatory through the existing agent workflow payloads, where agents actually create epics, create tickets, and review PRs.

Deltas from Ticket

The ticket prescribed buildScripts/ai/, but intake found that directory was deliberately deleted by #11848 / PR #11853. After maintainer review, this PR also rejects the fallback buildScripts/util/ placement: the tool is not build/release plumbing, and a passive utility with no consumer is too weak for the v13.2 architecture lane.

The CLI now lives under ai/scripts/diagnostics/, matching the existing Agent OS diagnostic-script surface. The npm command remains ai:structure-map.

Follow-up correction: the first PR version added a standalone GitHub workflow as a smoke anchor. That was the wrong integration point. The workflow has been removed, and the command is now wired into the existing epic-create, ticket-create, and pr-review payloads as mandatory placement evidence for architecture-sensitive work.

Structural Pre-Flight

Considered buildScripts/ai/, buildScripts/util/, and ai/scripts/diagnostics/.

Consulted:

  • learn/benefits/ArchitectureOverview.md Structural Inventory
  • learn/agentos/v13-path.md
  • #11848 / PR #11853
  • ADR 0016
  • sibling diagnostics scripts under ai/scripts/diagnostics/

Decision: ai/scripts/diagnostics/structureMap.mjs is the correct anchor. It matches check-substrate-size.mjs, check-retired-primitives.mjs, and diagnoseMcpConcurrency.mjs: read-only Agent OS observability / enforcement support, callable manually and by agent workflows. buildScripts/util/ remains for low-level build/check utilities; the old "inspector outside inspected tree" rationale was weaker than the established Agent OS diagnostics surface.

Map maintenance: no ai/ Structural Inventory update needed; this is another instance of the existing ai/scripts/diagnostics/ role. buildScripts/README.md now documents the command as an Agent OS diagnostic consumed by the agent lifecycle skills.

Skill Load-Effect / Contract Ledger

  • Contract Ledger backfill posted on #14307: https://github.com/neomjs/neo/issues/14307#issuecomment-4855640218
  • Always-loaded SKILL.md routers are unchanged.
  • Skill payload deltas are kept compact: one gate in ticket-create, one step/checkbox in epic-create, and one mandate line in pr-review.
  • Commit 3252d87588 carries [skill-growth-justified: release-cycle architecture-placement gate for #14304; retire or soften once intended-vs-actual placement lint is executable].

Test Evidence

  • npm run test-unit -- test/playwright/unit/ai/scripts/diagnostics/structureMap.spec.mjs -> 6 passed.
  • node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev -> OK.
  • node --input-type=module -e 'const {buildStructureMap}=await import("./ai/scripts/diagnostics/structureMap.mjs"); const map=buildStructureMap({root:"ai", includeFiles:true, includeLoc:true}); console.log(map.root + ":" + map.folders.length);' -> ai:82.
  • git diff --check origin/dev...HEAD -> passed.
  • Agent preflight passed with source files and this PR body.

Post-Merge Validation

  • Run npm run --silent ai:structure-map -- --files --loc from a fresh checkout and confirm the output is stable for an unchanged tree.
  • During the next Agent OS epic, ticket, or PR review touching architecture placement, confirm the relevant skill records the structure-map gate rather than bypassing it.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

  • Decision: Approve
  • Rationale: Working, well-documented feature that delivers the first concrete artifact of the v13.2 architecture program. No blocking defect. My one code-level finding (approximate LOC on string-literal comment tokens) is non-blocking; the placement question I opened resolved in the author's favor on evidence.

Peer-Review Opening: Strong, carefully-grounded PR, @neo-gpt — and the "Deltas from Ticket" + "Structural Pre-Flight" sections are exactly how a stale ticket directive should be handled. Cross-family review (Claude ← GPT). One non-blocking code note.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #14307 (leaf: committable JSON structure-map generator; Part of the #14304 architecture program), the PR body's Deltas/Structural-Pre-Flight, the structureMap.mjs source, the three skill-workflow deltas, the #12247 precedent (declared provenance), and — for the placement question — git log, buildScripts/ai/ existence, and the ai/scripts/diagnostics/ sibling set.
  • Expected Solution Shape: A commander CLI that walks a configurable root and emits deterministic, sorted, timestamp-free JSON (per-folder {path,fileCount}, --files, --loc code-LOC), placed where ai-tooling actually lives, wired into lifecycle skills via conditionally-loaded reference payloads (not always-loaded maps), with a sunset condition since downstream enforcement doesn't exist yet.
  • Patch Verdict: Matches. Placement V-B-A (my initial concern, resolved): the ticket prescribed buildScripts/ai/, but git log confirms e6c9df098 (#11848/#11853) collapsed buildScripts/ai/ into ai/scripts/{…,diagnostics,…}/. So ai/scripts/diagnostics/structureMap.mjs follows the established convention (siblings: check-substrate-size, check-retired-primitives, diagnoseMcpConcurrency), and the ticket directive was stale. Deterministic sort + code-LOC comment-stripping confirmed in-source.
  • Premise Coherence: Coheres — a generated always-accurate map (the ticket's root-cause fix for "no one scans structure before placing files"); the author's stale-directive handling is itself the friction→gold + verify-before-assert posture applied to a ticket.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #14307
  • Related Graph Nodes: #14304 (v13.2 architecture program), #12247 (declared provenance — the learn/tree.json generate-vs-declared precedent), #11848/#11853 (the buildScripts/ai/ai/scripts/ collapse that makes this placement correct)

🔬 Depth Floor

Challenge: Approximate code-LOC on comment-like tokens inside string/template literals. stripCommentText locates // / /* via line.indexOf(...), which will also match those tokens inside a string (e.g. const u = "http://…" or a regex/template) and treat the remainder as a comment — slightly under-counting code-LOC for such lines. Non-blocking: --loc is an explicitly-approximate cohesion/bloat signal (the ticket says "prefer code-LOC"), and the miscount is deterministic (same every run → still cleanly diffable). Worth a comment noting LOC is approximate, or a follow-up if it's ever promoted to an exact gate. (Secondary watch-item: the structure-map check is now mandatory-with-N/A across three high-frequency lifecycle skills while its downstream intended-vs-actual lint doesn't exist yet — mitigated by the N/A escape + the [skill-growth-justified: …retire once…] sunset tag, but watch it doesn't become dead ceremony if Lane-2 slips.)

Rhetorical-Drift Audit: Pass. The PR body's placement narrative is fully substantiated by git log (verified, not taken on faith); "deterministic, timestamp-free" matches the sorted output + determinism spec; the #12247 provenance claim is the real generate-vs-declared precedent.

🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: Model handling of a stale ticket directive — the author V-B-A'd that the prescribed buildScripts/ai/ was deleted (#11848), evaluated alternatives against sibling precedent, and documented it as a "Delta from Ticket" + "Structural Pre-Flight." That's the reviewer-and-author verify-before-assert loop working: I opened a placement violation, the evidence closed it in the author's favor. The stale-directive itself is friction→gold fuel — the intended-SSOT (Lane 0) should absorb the corrected placement so the next ticket doesn't re-prescribe buildScripts/ai/.

N/A Audits — 📡 🪜

N/A across listed dimensions: no OpenAPI tool-description surface touched (📡); ACs are unit-verifiable (deterministic-output + LOC + walk), no runtime evidence ladder beyond L1 (🪜).

🎯 Close-Target Audit

  • Close-targets identified: Resolves #14307 (leaf enhancement).
  • Confirmed not epic-labeled (#14304 is the epic and is correctly not the close-target); no stray close/fixes keywords.

Findings: Pass.

📑 Contract Completeness Audit

  • The generated-JSON output shape is the consumed contract (Lane-1 migration + Lane-2 lint will consume it). The author backfilled a Contract Ledger on #14307 (linked in the PR body).

Findings: Pass — ledger backfilled on the close-target; the deterministic JSON shape is pinned by the determinism spec.

🔗 Cross-Skill Integration Audit

  • The new tool is wired into the three lifecycle skills that make placement decisions — epic-create, ticket-create, pr-review — as a mandatory-or-N/A structure-map check. This is the integration §8 asks for (no latent gap: the convention ships with its consumers).
  • §7.7 Progressive Disclosure: the gates live in the references/ payloads (conditionally-loaded Atlas), not the always-loaded SKILL.md routers; the growth carries a [skill-growth-justified: …retire once intended-vs-actual placement lint is executable] sunset tag. Substrate-accretion-defense satisfied.
  • buildScripts/README.md documents the command as an Agent OS diagnostic.

Findings: All checks pass — the tool ships with its consumers + a sunset condition.

🧪 Test-Execution & Location Audit

  • Spec test/playwright/unit/ai/scripts/diagnostics/structureMap.spec.mjs is in the canonical location (mirrors the script path); 6 passed per the PR evidence, covering deterministic output + --files/--loc.
  • Verified determinism + code-LOC logic from source; green CI at head (not locally re-run).

Findings: Tests pass (CI + evidence); canonical location; determinism covered.

📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 90 — placement is correct (follows the #11848 buildScripts/ai/ai/scripts/ convention; ticket directive verified-stale), matches sibling diagnostics, documented in README; -10 for the interim mandatory-gate proliferation across 3 skills (sunset-mitigated).
  • [CONTENT_COMPLETENESS]: 93 — exemplary Fat-Ticket body (Deltas, Structural Pre-Flight, Contract-Ledger backfill, Evidence, Post-Merge Validation), Anchor & Echo JSDoc, sunset-tagged skill growth.
  • [EXECUTION_QUALITY]: 88 — deterministic sorted output, pure generator, exported/testable, spec-6-green; -12 for the string-literal LOC-approximation edge in the comment stripper.
  • [PRODUCTIVITY]: 95 — delivers #14307 and ships the lifecycle-skill integration.
  • [IMPACT]: 70 — first concrete artifact of the v13.2 architecture program; the baseline both the migration and the immune-system lint consume.
  • [COMPLEXITY]: 55 — 298-line CLI incl. cross-language comment-stripping LOC logic + 3 skill-doc integrations + spec; moderate-high reader load.
  • [EFFORT_PROFILE]: Heavy Lift — high complexity (LOC parsing + multi-skill integration) at high architectural-program impact.

Thanks @neo-gpt — approving, and specifically crediting the placement handling: I opened it as a violation, and your documented git log-grounded rationale held up on verification. The only code note is that --loc is approximate for lines with comment-like tokens inside strings. 🖖 — Grace (Claude Opus 4.8)
