+# Phase 5 — Exit evidence
+
+**Captured:** 2026-05-11T16:15Z (Track E landing).
+
+Per [`phase5-plan.md` §10 "Phase 5 Done — Definition"](phase5-plan.md):
+clean runs of the four enforcement gates plus per-PR CI wiring + a
+weekly cron firing are the documented exit. This doc mirrors the
+[`phase4-evidence.md`](phase4-evidence.md) shape: one section per
+gate, "What this proves" wrap-up, then each §10 done-criterion cited
+green.
+
+Phase 5 is the operational-loop close: with all four watchdogs live,
+every architectural promise the framework makes is now backed by an
+automated CI check rather than maintainer discipline.

+
+Phase 4 closed at 51 cases. Phase 5 added 65 more across the four
+gates + the carry-over fix:
+
+| Track | Module | Cases |
+|---|---|---|
+| A — freshness | `test_check_freshness.py` | 15 |
+| B0 — validate-repo-meta binary-URL fix | `test_validate_repo_meta.py` | 5 |
+| B — link-check | `test_check_links.py` | 13 |
+| C — license-reconcile | `test_check_licenses.py` | 18 |
+| D — schema-version policing | `test_check_schema_compat.py` | 14 |
+
+## `make check-freshness` — clean (worst=OK)
+
+Per [phase5-plan.md §2](phase5-plan.md). Status taxonomy:
+OK / WARN / STALE / MISSING / INVALID; aggregator ranks
+**STALE > MISSING > INVALID > WARN > OK** (STALE is the strongest
+fix-now signal; INVALID/MISSING outrank WARN because they signal a
+real bug, not just age).
+
+10 catalog entries + 4 recipes, all dated 2026-05-10 or 2026-05-11:
+
+```
+check-freshness: clean (worst=OK)
+```
+
+PR-mode runs default thresholds (`--warn-days 90 --stale-days 180`;
+WARN allowed). The weekly cron firing escalates with `--strict` so
+a freshness slip past 90 days surfaces within 7 days.
+
+## `make check-links` — clean (offline; 59 URLs catalogued)
+
+Per [phase5-plan.md §3](phase5-plan.md). Walks every URL surfaced
+by:
+
+* `profile/llms.txt` — Markdown link targets.
+* `profile/tools.json` — top-level `$schema` + every
+  `tools.<key>.<field>_url` value.
+* `profile/task_index.json` — top-level `$schema` + every `doc`
+  field across every category/row.
+
+```
+check-links: clean (offline; 59 URLs catalogued)
+```
+
+PR-mode is `--offline` (inventory only — no network round-trip).
+The weekly cron firing on the handshake job runs the full HEAD walk:
+200/301/302 OK, 405→GET fallback, anything else FAIL. Binary URLs
+(`.whl` / `.tar.gz` / …) work the same way — HEAD only, no decode.
+
+**Carry-over fix in the same PR (B0):** `validate-repo-meta.py`'s
+UTF-8-decode crash on binary `exposes.*` URLs is fixed. The
+pre-Phase-4 workaround `ARGS=--no-resolve` is no longer required;
+`make check-repo-meta` in full-resolve mode now works against the
+v0.1.0 wheel URL.
+
+## `make check-licenses` — clean (worst=SKIP)
+
+Per [phase5-plan.md §4](phase5-plan.md). Per-license signature dict
+— **AGPL-3.0**, **Apache-2.0**, **MIT**, **BSD-3-Clause**,
+**GPL-3.0** — each with three distinct substring markers. A body
+matches when ≥ 2 markers hit (per plan §9: prefer false negatives
+over false positives). Specificity ordering: AGPL is tried before
+GPL because both share "GENERAL PUBLIC LICENSE" + "Version 3" but
+only AGPL carries "AFFERO".
+
+```
+check-licenses: clean (worst=SKIP)
+```
+
+9 INVENTORIED rows + 1 SKIP (`m-modern-corpus` declares
+`LicenseRef-mixed-per-subdir` — per-subdir licensing can't be
+reconciled by signature match).
+
+PR-mode is `--offline`; the weekly cron firing fetches each repo's
+`LICENSE` at `raw.githubusercontent.com/<repo>/main/LICENSE` and
+signature-matches the body.
+
+## `make check-schema-compat` — clean
+
+Per [phase5-plan.md §5](phase5-plan.md). Diffs
+`profile/tools.schema.json` + `profile/task_index.schema.json`
+between a base ref (default `origin/main`) and HEAD; enforces two
+rules:
+
+1. If `schema_compat` bumps in either schema,
+   `profile/schema-changelog.md` must appear in the same diff →
+   otherwise `MISSING_CHANGELOG_ROW` (exit 1).
+2. Non-additive shape changes without a `schema_compat` bump →
+   `NON_ADDITIVE_WITHOUT_BUMP` (exit 1). Three heuristics:
+   required field removed, enum value removed, `additionalProperties`
+   tightened `true` → `false`.
+
+```
+check-schema-compat: clean
+```
+
+**Per-PR-only gate** — no cron firing. `schema_compat` bumps land
+via PRs by definition; a periodic re-run adds no signal. Critical
+wiring detail: the `check` job's `actions/checkout@v4` uses
+`fetch-depth: 0` so `git show origin/main:…` works in CI.
+
+## Companion gates (Phase-3-era, still passing)
+
+```
+make handshake          — step 8 — exit 0 (success)
+make recipes-check      — 4 recipe(s) clean
+make validate-catalog   — OK
+```
+
+The Phase-3 discovery handshake, recipe structural gate, and
+catalog drift gate continue to pass after the Phase 5 additions —
+no regression from layering the four new watchdogs on top.
+
+## What this proves
+
+1. **Every architectural promise has a watchdog.** Pre-Phase-5,
+   `verified_on` correctness, URL liveness, declared-license
+   accuracy, and schema-compat discipline lived in maintainer heads.
+   Post-Phase-5, each has an automated gate that surfaces drift —
+   either per-PR (synchronous, fast) or via the weekly cron
+   firing (within 7 days; matches the parent-plan §7 Phase-5 exit
+   criterion).
+2. **Failures are structured.** Each gate emits a stable status
+   taxonomy (OK / WARN / STALE / FAIL / MISMATCH / etc.) plus a
+   Markdown table sorted worst-first. CI logs are immediately
+   actionable.
+3. **TDD coverage holds.** Every behavior added in Phase 5 has a
+   pinned regression test, including the validate-repo-meta
+   binary-URL fix (B0) and the schema-compat ephemeral-git-repo
+   end-to-end cases. 116/116 total.
+4. **Offline + live modes split cleanly.** PR-mode is `--offline`
+   (no network, no flake). Weekly cron mode fetches live URLs +
+   live LICENSE bodies. The split keeps per-PR CI fast while still
+   surfacing upstream drift within a week.
+5. **CI fetch-depth gotcha is fixed.** Track D's
+   `check-schema-compat.py` needs `origin/main` reachable in the
+   CI runner's git history; the workflow change to `fetch-depth: 0`
+   keeps the gate working without slowing the runner (this repo is
+   small).
+
+## Phase 5 closed
+
+All seven [`phase5-plan.md` §10](phase5-plan.md) done-criteria met:
+
+1. **`profile/build/check-freshness.py`** exists, TDD-covered
+   (15 cases), `make check-freshness` exits 0 on `main` ✓ (Track A
+   PR #32 / `e9e00cb`).
+2. **`profile/build/check-links.py`** exists, TDD-covered
+   (13 cases), `make check-links --offline` and full-fetch both
+   exit 0 on `main`. The `validate-repo-meta.py` binary-URL bug is
+   fixed (5 cases) ✓ (Track B PR #33 / `16bbd08`).
+3. **`profile/build/check-licenses.py`** exists, TDD-covered
+   (18 cases), `make check-licenses` exits 0 across all 10 active
+   repos ✓ (Track C PR #34 / `5d9a995`).
+4. **`profile/build/check-schema-compat.py`** exists, TDD-covered
+   (14 cases), `make check-schema-compat` exits 0 against `main`
+   (no schema bump in any Phase-5 PR) ✓ (Track D PR #35 /
+   `8792787`).
+5. **`.github/workflows/ci.yml`** runs all four `--offline`
+   variants on every push/PR ✓ (`Freshness gate` + `Link inventory`
+   + `License inventory` + `Schema-version policing` steps in the
+   `check` job).
+6. **The weekly cron firing** runs `--strict` freshness + live
+   link-check + full LICENSE-fetch ✓ (handshake job; Monday-14:00
+   UTC cron from Phase-3 Track D).
+7. **`docs/ai-discoverability/phases/phase5-evidence.md`** captures
+   clean runs of every gate, with each criterion cited green ✓
+   (this file).
+
+When all seven are true (now), the AI-discoverability framework's
+operational loop is complete. Future phases — if any — address
+*growth* scenarios (more repos, more tools, more catalog kinds)
+rather than enforcement coverage.
+
+## Out-of-scope follow-ups noted in the plan
+
+These remain open after Phase 5, by design:
+
+- **Phase-3-era YAML parser limitation** in `run-recipe.py`'s
+  `_parse_minimal_yaml` (no `>` block scalars / `[]` inline empty
+  arrays). The four shipped recipes work around it; the gate runs
+  clean.
+- **Live-fetch freshness mode.** Track A's `--strict` cron only
+  re-reads the committed catalog's `verified_on`; a future
+  improvement would walk each repo's upstream `repo.meta.json` and
+  detect maintainers who re-verified but forgot to bump. Deferred
+  per plan §9.
+- **Multi-license per-file detection.** Phase-5 Track C reconciles
+  the project-level `LICENSE` file against the declared license;
+  per-file SPDX expressions are explicitly out of scope per plan
+  §0 "Not in scope".
+
+Phase 5 close. The framework's invariants are now CI-enforced.
