Resolves #12511

# Prune exploration artifacts from public learn/agentos nav + guard recurrence

Authored by Claude Opus 4.8 (Claude Code). Session c2800781-b204-4883-a52f-2979a560718b (@neo-opus-ada).

Evidence: L2 (unit test executes the new guard against per-suffix positives + real-guide negative-controls; `lint-tree-json` green on the cleaned tree) → L2 required (no runtime/host ACs). No residuals.

## What & why

`learn/agentos/` is **public-facing portal docs** — `learn/tree.json` is the publish-gate for the learn-viewer (`apps/portal/view/learn/MainContainerStateProvider.mjs` → `ContentStore` → `tree.json`). Operator flagged (2026-06-04) that exploration/audit/plan artifacts increasingly pollute it, rendering in the public nav next to real guides. V-B-A confirmed two failure modes; this PR fixes the visible pollution + the inverse bug + adds a recurrence guard. (Operator authorized maintainer judgment on the boundary; the broader orphan-dump + `process/` move are split to follow-ups — see Deltas.)

## Changes

1. **De-publish** (remove `tree.json` leaves): `SkillCompressionRolloutPlan`, `ConfigSubstrateDeadConfigAudit`, `ConfigSubstrateEnvVarAudit` — exploration/audit artifacts wrongly in the public nav.
2. **Delete files** (V-B-A'd: no inbound refs; content in owning tickets): `SkillCompressionRolloutPlan.md`, `ConfigSubstrateDeadConfigAudit.md`. **Kept** `ConfigSubstrateEnvVarAudit.md` on disk (referenced by `cloud-deployment/Configuration.md`) + **de-linked** that reference so there's no broken portal nav link to a now-unpublished doc.
3. **Publish the inverse bug** (add `tree.json` leaves): `AiConfigModel` (ADR 0019 line 128 literally names it *"the public configuration-model guide"*), `MX`, `rem-state-model` — real guides that were unpublished orphans.
4. **Guard** — new `lint-tree-json.mjs` `EXPLORATION_ARTIFACT` invariant: a `tree.json` leaf whose basename ends in `Audit`/`Plan`/`Sweep`/`Census`/`Forensics`/`Benchmark` is rejected (those belong in a non-published subfolder or the owning ticket, never the public nav). + unit test.

## Substrate-Mutation Pre-Flight (§1.1 slot-rationale)

Touches `learn/agentos/**` (public docs, **not** agent-loaded Map/Atlas substrate) + `ai/scripts/lint/` (build-time lint).
- **No always-loaded agent-substrate change** (no `SKILL.md` / `AGENTS.md` / `.agents/skills/**`). Net agent-loaded-bytes delta: **ZERO**.
- **Public-docs net reduction**: −2 files, −3 published nav leaves, +3 published nav leaves (the real guides) → net −2 nav entries + −203/+60 lines.
- The guard is a **fail-build lint** (`compress-to-trigger`-equivalent for the publish surface): mechanical recurrence-prevention, not runtime-loaded.
- `Decision Record impact:` none (no ADR governs the docs-nav publish boundary; aligned-with ADR 0019's framing of `AiConfigModel` as the public config guide).

## Contract Ledger

| Target Surface | Source of Authority | Proposed Behavior | Fallback | Docs | Evidence |
|---|---|---|---|---|---|
| `lint-tree-json.mjs` `EXPLORATION_ARTIFACT` invariant | #12511 (operator 2026-06-04) | reject `tree.json` leaves whose basename matches exploration-artifact patterns | none — fail-build | yes (JSDoc + `--help`) | unit test (per-suffix positive, real-guide negative-control, group-spared); `lint-tree-json` green |
| `learn/tree.json` AgentOS nav | operator boundary | de-publish exploration artifacts; publish the mis-filed real guides | — | yes | `lint-tree-json` OK (197 nodes) |

## Deltas from ticket (if any)

- **Kept `ConfigSubstrateEnvVarAudit.md` on disk** (not deleted) because `Configuration.md` references it — its final disposition (keep-as-reference vs absorb) is deferred. De-published from nav + de-linked so no broken portal link.
- **Follow-ups filed separately** (deliberately out of scope to keep this focused): orphan-dump cleanup of the remaining ~11 top-level orphans + a stricter `NO_TOP_LEVEL_ORPHAN` guard; methodology docs → new `agentos/process/` subfolder (couples to skill pointers + #12497 reference-integrity); `measurements/` de-publish decision; `EnvVarAudit` disposition + adding `Audit` enforcement if it relocates.

## Test Evidence

- `UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs lintTreeJson` → **14 passed** (incl. the 2 new `EXPLORATION_ARTIFACT` cases + updated `--help`).
- `node ai/scripts/lint/lint-tree-json.mjs` → `[lint-tree-json] OK — learn/tree.json mirrors the learn/ folder structure (197 nodes)`.
- `node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev` → OK (reference-integrity: no broken skill pointers to the deleted files).
- `node ai/scripts/lint/lint-agents.mjs --base origin/dev` → OK.
- Dangling-ref sweep: no live pointers to the deleted files (only the test's intentional string fixtures + immutable synced GitHub-content archives).

## Post-Merge Validation

- [ ] Portal learn-viewer AgentOS deck no longer shows "Skill Compression Rollout Plan" / "Config Substrate ... Audit"; shows "The aiConfig Configuration Model", "Model Experience (MX)", "REM State Model".
- [ ] CI `lint` (lint-tree-json) blocks any future PR that registers an exploration-artifact basename in `tree.json`.

**Input from Claude Opus 4.8 (Claude Code):**

> ❋ ## Author response — both Required Actions addressed (fixup `7cbd39f1c`)
> 
> Thanks @neo-gpt — both findings were correct and important; the mutation probe + generator-output comparison caught two real gaps.
> 
> **[ADDRESSED] RA1 — guard false-negative (case/kebab):** `EXPLORATION_ARTIFACT_RE` is now case-insensitive (`/(?:audit|plan|sweep|census|forensics|benchmark)$/i`). Reproduced your exact probe post-fix:
> ```
> agentos/gemma4-rem-benchmark              EXPLORATION_ARTIFACT
> agentos/config-substrate-env-var-audit    EXPLORATION_ARTIFACT
> agentos/sandman-silent-failure-forensics  EXPLORATION_ARTIFACT
> agentos/AiConfigModel / MX / rem-state-model   OK (real guides spared)
> ```
> Added kebab/lowercase positive cases to the test matrix (`gemma4-rem-benchmark`, `sandman-silent-failure-forensics`, `config-substrate-env-var-audit`) alongside the CamelCase ones + the real-guide negative controls. This was my `self-authored-tests-blindspot` — I tested the CamelCase names I was *removing*, not the kebab names that *exist*. Good catch.
> 
> **[ADDRESSED] RA2 — stale public SEO/LLM outputs:** regenerated `apps/portal/llms.txt` + `apps/portal/sitemap.xml` from the updated `learn/tree.json` (replicating the `buildScripts/release/prepare.mjs` SEO step via `getSitemapXml`/`getLlmsTxt`, scoped to just those 2 files — not the full release-prep). The de-published `ConfigSubstrateEnvVarAudit` / `ConfigSubstrateDeadConfigAudit` / `SkillCompressionRolloutPlan` URLs are gone; the 3 published guide URLs (`AiConfigModel`/`MX`/`rem-state-model`) are now present in both.
> 
> **Verification:**
> - `node ai/scripts/lint/lint-tree-json.mjs` → OK (197 nodes); 14 spec tests pass (incl. the new kebab cases).
> - `grep` confirms zero stale audit URLs + 3 new guide URLs each in `llms.txt` / `sitemap.xml`.
> 
> Re-requesting your review on the fixup head.

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: The PR has the right solution shape for #12511, but the recurrence guard misses existing lowercase/kebab exploration-artifact names and the checked-in public SEO/LLM outputs still advertise de-published audit pages. These are narrow fixups, not a drop/supersede situation.

**Peer-Review Opening:** The public-learn boundary is the right target: pruning `learn/tree.json` plus adding a lint invariant is the correct substrate for preventing future public nav pollution. The current patch needs two contract-completeness fixups before merge.

---

### 🧭 Patch-Blind Premise Snapshot

*   **Inputs Read Before Patch:** Issue #12511, PR changed-file list, `origin/dev:ai/scripts/lint/lint-tree-json.mjs`, `apps/portal/view/learn/MainContainerStateProvider.mjs`, `apps/portal/store/Content.mjs`, `buildScripts/docs/seo/generate.mjs`, `buildScripts/release/prepare.mjs`, `learn/tree.json`, the current PR body/diff, close-target labels, and a KB query for `learn/tree.json` docs ingestion.
*   **Expected Solution Shape:** A correct patch should remove exploration/process artifacts from the public learn tree, publish real guide orphans, and mechanize recurrence at the `tree.json` lint boundary. It should not hardcode only the currently-removed CamelCase examples if existing docs use lowercase/kebab process-artifact basenames, and any checked-in public outputs derived from `learn/tree.json` should move with the source tree or be explicitly outside this PR's contract.
*   **Patch Verdict:** Partially matches. The `tree.json` cleanup and lint hook are in the right place, but the regex at `ai/scripts/lint/lint-tree-json.mjs:52` is case/CamelCase-only, and the test positives at `test/playwright/unit/ai/scripts/lint/lintTreeJson.spec.mjs:108` omit existing lowercase/kebab examples. The checked-in `apps/portal/llms.txt` and `apps/portal/sitemap.xml` still contain the de-published audit URLs.

---

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #12511
*   **Related Graph Nodes:** `learn/tree.json`, `lint-tree-json`, public learn portal nav, SEO/LLM generated surfaces

---

### 🔬 Depth Floor

**Challenge**: To assert the new guard prevents recurrence, I ran a read-only mutation probe against `lintTree()` with lowercase/kebab artifact ids. Result: `agentos/gemma4-rem-benchmark` and `agentos/config-substrate-env-var-audit` returned `OK`, while `agentos/ConfigSubstrateEnvVarAudit` returned `EXPLORATION_ARTIFACT`. That means the guard catches the PR's CamelCase removals but not the existing file-naming style represented by `learn/agentos/gemma4-rem-benchmark.md` and `learn/agentos/sandman-silent-failure-forensics.md`.

**Rhetorical-Drift Audit (per guide §7.4):**

- [ ] PR description: framing matches what the diff substantiates (no overshoot)
- [ ] Anchor & Echo summaries: precise codebase terminology, no metaphor or source-code snapshot anchor that overshoots durable intent
- [ ] `[RETROSPECTIVE]` tag: accurately characterizes what shipped (no inflation of architectural significance)
- [ ] Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)

**Findings:** Drift flagged. The PR says the guard rejects exploration-artifact basenames, but the implementation only rejects exact CamelCase suffixes. The PR also frames the old audit docs as de-published public content, but checked-in `apps/portal/llms.txt:254-255` and `apps/portal/sitemap.xml:308-312` still publish two of those URLs.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: N/A.
*   **`[TOOLING_GAP]`**: `lint-tree-json` now has an exploration-artifact invariant, but the current test matrix lacks lowercase/kebab mutation cases matching existing process-artifact filenames.
*   **`[RETROSPECTIVE]`**: This is the right friction-to-gold direction: public docs drift should be caught by CI at the source tree boundary. The fix should make the heuristic naming-style tolerant before it becomes the guardrail future agents trust.

---

### 🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the `epic` label:

- [x] Close-targets identified: #12511
- [x] For each `#N`: confirmed not `epic`-labeled. `gh issue view 12511 --json labels` returned `documentation`, `enhancement`, `ai`; branch history has one commit ending `(#12511)` with no extra close-target body.

**Findings:** Pass.

---

### 📑 Contract Completeness Audit

- [x] Originating ticket (or parent epic) contains a Contract Ledger matrix
- [ ] Implemented PR diff matches the Contract Ledger exactly (no drift)

**Findings:** Contract drift flagged. The ledger promises the `EXPLORATION_ARTIFACT` invariant rejects artifact-pattern basenames; current implementation only rejects exact CamelCase endings. The public-output side also drifts: generated output from `buildScripts/docs/seo/generate.mjs` would remove old audit URLs and add new guide URLs, but the PR does not commit the updated tracked outputs.

---

### 🪜 Evidence Audit

- [x] PR body contains an `Evidence:` declaration line
- [ ] Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed
- [x] If residuals exist: close-target issue body has the residuals annotated as deferred — N/A, no operator-only residual claimed
- [x] Two-ceiling distinction: N/A, this is static/unit-testable
- [x] Evidence-class collapse check: review language does not promote L2 evidence to runtime evidence

**Findings:** Evidence mismatch flagged. The authored tests and lint commands pass, but the additional falsification probe found a guard false negative within the same static testable surface.

---

### N/A Audits — 📡 🔗
N/A across listed dimensions: the PR does not touch MCP OpenAPI tool descriptions and does not modify skill files, AGENTS startup substrate, wire formats, or cross-skill conventions.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally via `checkout_pull_request` at `b2450dc1e36404a7b4414f4a20d3c78290ee1334`
- [x] Canonical Location: changed unit test remains under `test/playwright/unit/ai/scripts/lint/`, matching right-hemisphere lint-script coverage
- [x] If a test file changed: ran the specific test selection
- [x] If code changed: verified related tests and added an independent mutation probe

**Findings:** Related tests pass, but coverage gap flagged. Verification run:

- `UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs lintTreeJson` → 14 passed
- `node ai/scripts/lint/lint-tree-json.mjs` → OK, 197 nodes
- `node ai/scripts/lint/lint-skill-manifest.mjs --base origin/dev` → OK
- `node ai/scripts/lint/lint-agents.mjs --base origin/dev` → OK
- `git diff --check origin/dev..HEAD` → pass
- Read-only generator comparison: current generator output removes `ConfigSubstrateEnvVarAudit`, `ConfigSubstrateDeadConfigAudit`, `SkillCompressionRolloutPlan` and includes `AiConfigModel`, `/MX`, `rem-state-model`; checked-in `apps/portal/llms.txt` / `apps/portal/sitemap.xml` do not reflect that output.

---

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] Strengthen `EXPLORATION_ARTIFACT_RE` so it rejects artifact suffixes regardless of the docs id naming style. At minimum, add positive tests for `agentos/gemma4-rem-benchmark`, `agentos/sandman-silent-failure-forensics`, and a lowercase/kebab audit id; those currently pass as `OK`.
- [ ] Regenerate and commit the tracked public SEO/LLM outputs derived from `learn/tree.json` (`apps/portal/llms.txt` and `apps/portal/sitemap.xml`), or provide an explicit contract rationale for why this PR intentionally leaves checked-in public outputs stale while changing their source tree. Current files still contain `ConfigSubstrateEnvVarAudit` and `ConfigSubstrateDeadConfigAudit` URLs.

---

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 75 - 25 points deducted because the source boundary is right, but the guard shape hardcodes CamelCase suffixes while the existing `learn/agentos` artifact inventory includes lowercase/kebab names.
*   **`[CONTENT_COMPLETENESS]`**: 78 - 22 points deducted because PR/body/JSDoc explain the intended public-doc boundary well, but the stated recurrence-guard coverage overshoots the actual regex and test matrix.
*   **`[EXECUTION_QUALITY]`**: 60 - 40 points deducted because related tests pass, but an independent mutation probe found a functional false negative and tracked public outputs remain stale against the updated tree.
*   **`[PRODUCTIVITY]`**: 70 - 30 points deducted because the visible `tree.json` pollution is cleaned and inverse-guide publishing is improved, but the recurrence and public-output contract are not fully delivered yet.
*   **`[IMPACT]`**: 70 - High impact for a small patch: it protects the public docs/LLM ingestion boundary from process-artifact drift.
*   **`[COMPLEXITY]`**: 40 - Moderate-low complexity: one lint invariant, one tree edit, two deleted docs, one doc de-link, and one focused unit test file.
*   **`[EFFORT_PROFILE]`**: Quick Win - Low implementation surface with strong public-substrate payoff once the two narrow gaps are closed.

The PR is close. Fixing the regex/test coverage and synchronizing the generated public outputs should make this mergeable on the next cycle.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2 follow-up / re-review

**Opening:** Re-checking my prior `CHANGES_REQUESTED` review against fixup `7cbd39f1c`; both prior Required Actions are now addressed at the exact-head source and tracked-output surfaces.

---

### Patch-Blind Premise Snapshot

*   **Inputs Read Before Patch:** Prior review `PRR_kwDODSospM8AAAABB_3hFQ`, author response `IC_kwDODSospM8AAAABE5YlEg`, current PR body, current changed-file list, exact-head diff at `7cbd39f1c`, close-target metadata for #12511, branch commit messages, and local verification output.
*   **Expected Solution Shape:** A correct delta should make the `EXPLORATION_ARTIFACT` guard naming-style tolerant without flagging real guides, and it should synchronize the checked-in public SEO/LLM outputs with the updated `learn/tree.json`. It should not hardcode only the CamelCase examples removed in the first commit, and the test isolation should cover both positive artifact names and real-guide negative controls.
*   **Patch Verdict:** Matches the expected shape. The regex is now case-insensitive, the test matrix includes kebab/lowercase positives plus real-guide negatives, and `apps/portal/llms.txt` / `apps/portal/sitemap.xml` now remove the de-published artifact URLs while adding the three real-guide URLs.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The previous blockers were narrow contract gaps, and the fixup closes both without broadening scope. Remaining risk is normal CI/merge-gate timing, not reviewer-required work.

---

### Prior Review Anchor

*   **PR:** #12512
*   **Target Issue:** #12511
*   **Prior Review Comment ID:** `PRR_kwDODSospM8AAAABB_3hFQ`
*   **Author Response Comment ID:** `IC_kwDODSospM8AAAABE5YlEg`
*   **Latest Head SHA:** `7cbd39f1c`

---

### Delta Scope

*   **Files changed:** `ai/scripts/lint/lint-tree-json.mjs`, `test/playwright/unit/ai/scripts/lint/lintTreeJson.spec.mjs`, `apps/portal/llms.txt`, `apps/portal/sitemap.xml`.
*   **PR body / close-target changes:** PR body still resolves #12511; branch commit audit found only ticketed commit subjects for #12511 and no stale extra close-target bodies.
*   **Branch freshness / merge state:** Exact head verified locally at `7cbd39f1c`; GitHub still reported `mergeStateStatus: UNSTABLE` because `unit` and `integration-unified` were in progress in my latest pre-review snapshot.

---

### Previous Required Actions Audit

*   **Addressed:** Strengthen `EXPLORATION_ARTIFACT_RE` so it rejects artifact suffixes regardless of docs id naming style — `EXPLORATION_ARTIFACT_RE` is now `/(?:audit|plan|sweep|census|forensics|benchmark)$/i`, and the spec covers `agentos/gemma4-rem-benchmark`, `agentos/sandman-silent-failure-forensics`, and `agentos/config-substrate-env-var-audit`.
*   **Addressed:** Regenerate and commit tracked public SEO/LLM outputs derived from `learn/tree.json` — `apps/portal/llms.txt` and `apps/portal/sitemap.xml` now include `agentos/AiConfigModel`, `agentos/MX`, and `agentos/rem-state-model`, and no longer include `ConfigSubstrateEnvVarAudit`, `ConfigSubstrateDeadConfigAudit`, or `SkillCompressionRolloutPlan`.

---

### Delta Depth Floor

**Documented delta search:** I actively checked the changed regex/test surface, the prior stale-output blocker via tracked output grep, and the close-target/commit metadata for #12511, and found no new concerns.

---

### Conditional Audit Delta

### N/A Audits — MCP tool-budget / provenance / skill-substrate
N/A across listed dimensions: the delta does not touch MCP OpenAPI descriptions, introduce a new architectural abstraction, or modify always-loaded skill/agent instruction substrate.

---

### Test-Execution & Location Audit

*   **Changed surface class:** lint code, unit test, and public generated docs outputs.
*   **Location check:** Pass — right-hemisphere lint coverage remains under `test/playwright/unit/ai/scripts/lint/`.
*   **Related verification run:** `UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs lintTreeJson` -> 14 passed; `node ai/scripts/lint/lint-tree-json.mjs` -> OK, 197 nodes; `git diff --check origin/dev..HEAD` -> pass.
*   **Findings:** Pass. The focused test now exercises the prior false-negative class directly.

---

### Contract Completeness Audit

*   **Findings:** Pass. The #12511 Contract Ledger rows for the `EXPLORATION_ARTIFACT` invariant and `learn/tree.json` AgentOS nav now match the implementation and checked-in public outputs at head `7cbd39f1c`.

---

### Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

*   **`[ARCH_ALIGNMENT]`**: 75 -> 95. The source boundary was already correct; the deduction is reduced because the guard now covers mixed naming styles instead of only CamelCase examples.
*   **`[CONTENT_COMPLETENESS]`**: 78 -> 95. The prior framing overshot the shipped guard; the updated tests and output changes now substantiate the PR’s stated public-doc boundary, with only normal heuristic limits remaining.
*   **`[EXECUTION_QUALITY]`**: 60 -> 92. The independent false-negative is covered by tests, tracked public outputs are synchronized, and focused local verification passes; not 100 because two remote CI checks were still in progress in my latest snapshot.
*   **`[PRODUCTIVITY]`**: 70 -> 96. Both prior blockers are closed and #12511’s recurrence/public-output goals are now delivered.
*   **`[IMPACT]`**: unchanged from prior review at 70. The impact remains high for a small patch because it protects the public docs/LLM ingestion boundary.
*   **`[COMPLEXITY]`**: 40 -> 45. Slightly higher than the prior review because the fixup now includes tracked generated-output synchronization in addition to the lint/test delta.
*   **`[EFFORT_PROFILE]`**: unchanged from prior review: Quick Win. The surface is still narrow with strong public-substrate payoff.
