machine-docs: move all per-phase coordination files out of repo root

STATUS/BACKLOG/REVIEW/JOURNAL for bsky/conc/dstamp/kuma/lvl5/mailu/rcust/shot
(32 files) were at the repo root; move them into machine-docs/ to match the
mandated file-location rule (DECISIONS/DEFERRED/INBOX + older phases already
live there). AGENTS.md gains an explicit File-location rule. No content change.

+# STATUS — Phase lvl5 (L5 lint rung + de-cap)
+
+## DONE
+
+Phase complete 2026-06-11: M1 PASS (cfc87fd) + M2 PASS (13cad1f), both <24h, no VETO.
+The 5-rung ladder (L5 = abra recipe lint on the exact tested ref) and the de-capped level
+semantics (pass/fail/skip/unver; fails AND unverified rungs block, intentional skips climb;
+no cap/cap_reason anywhere) are live on main @ a521d43 and verified end-to-end
+(results.json schema 2 → card → dashboard → badge → PR comment, drone path included).
+Cleanup done: throwaway PR custom-html#4 closed, branch lvl5-lintdemo deleted; WC5
+stage-completeness observation filed in machine-docs/DEFERRED.md.
+
+## M2 claim — proven in real CI
+
+**WHAT:** plan-phase-lvl5 §4 M2: P3 matrix complete for ALL 19 enrolled recipes; P4 runs done
+(genuine L5, lint-blocked L4, N/A-skip climb, drone path ×3, canaries at re-derived designed
+levels, synthesized unver-blocks run); old artifacts render; durations not inflated;
+before/after table complete; card/dashboard/badge visually verified.
+
+**WHERE:** main @ `dc924c679b4ae6dd1e21bfe9d231acb28b58ddf8` (implementation merged 08e6cc8 after
+M1 + PR-path fix 68c3486). Evidence runs (all artifacts at
+`https://ci.commoninternet.net/runs/<n>/{results.json,summary.png,badge.svg,lint.txt}`):
+
+| run | what it proves | EXPECTED content |
+|---|---|---|
+| 398 hedgedoc cold | genuine L5, full clean climb | level=5, all 5 rungs pass, schema=2, no cap keys, dur 100s |
+| 399 custom-html-tiny cold | N/A-skip climb (was L2 @ #205) | level=5, backup_restore=skip + declared reason in skips.intentional, dur 45s |
+| 405 custom-html PR4 (!testme) | lint-blocked L4 + verdict-neutral | level=4, lint=fail rules_failed=[R011], **drone build status SUCCESS**, dur 61s |
+| 406 immich PR2 (!testme) | drone path L5 on real PR | level=5, dur 199s (shot baseline 198-199s — no inflation) |
+| 407 plausible PR3 (!testme) | drone path L5 on real PR | level=5, dur 164s (shot baseline 166s) |
+| 413 mumble cold | table row (no prior artifact) | level=5, dur 80s |
+| 415/416 bkp-bad/rst-bad (SRC+REF) | canaries at re-derived designed level | **verdict FAILURE (red)**, level=1, rungs {install pass, upgrade skip (no version tags on mirror), backup_restore fail, functional unver, lint pass} |
+| host `/var/lib/cc-ci-runs/lvl5-unver-demo/results.json` | synthesized unver-blocks (mission ex. #3) | hand-run STAGES=install,upgrade,custom on custom-html: level=2, backup_restore=unver in skips.unintentional, functional+lint pass above it |
+
+**HOW to verify (cold):**
+1. Fresh clone main; `cc-ci-run -m pytest tests/unit/ -q` → EXPECTED **247 passed** (new since M1:
+   `test_run_lint_detached_pr_tree_lints_exact_ref` — PR-path regression, see fix 68c3486:
+   abra lint checks out the repo's DEFAULT BRANCH, so run_lint forces local `main` AT the tested
+   ref + repoints origin to the scratch itself; found live in builds 400-402 where the rung
+   correctly degraded to unver/level 4 with run verdicts unaffected).
+   `nix develop .#lint --command bash scripts/lint.sh` → PASS.
+2. Fetch each run's results.json above and check the EXPECTED column; drone build statuses via
+   API (only 415/416 red — and red by tier failure, not by lint).
+3. Visuals: Read `summary.png` of 398 (level 5 of 5, lint row PASS, green 5 badge), 399
+   (backup/restore row "INTENTIONAL SKIP" + reason, level 5), 405 (lint row FAIL red, level 4 of
+   5, badge #a0b93f); badges are number+colour ONLY.
+4. Old artifacts: `/runs/370/{results.json,summary.png}` 200 + render (pre-lvl5 schema-1 with cap
+   fields); dashboard `/` and `/recipe/immich` 200 with mixed-schema rows; unit history-compat
+   tests (test_card/test_dashboard old-schema cases).
+5. lint.txt served: `/runs/398/lint.txt` 200 (full abra table; rc/status header).
+6. P3 matrix + §2.9 before/after table: BACKLOG-lvl5.md (19/19 lint pass sweep — re-runnable per
+   the documented scratch method; baseline column from latest artifacts; REAL column from the
+   runs above; canary re-derivation note).
+7. Dashboard runtime is the rolled image `cc-ci-dashboard:15addbc7bf45` (reconcile per DECISIONS
+   Phase 3/U2 — no host switch).
+
+**Notes for the verdict:**
+- The throwaway lint-violation PR (custom-html#4, branch lvl5-lintdemo) is left OPEN and marked
+  do-not-merge so you can re-run `!testme` independently; Builder will close branch+PR after M2.
+- Level shifts vs baseline are exactly the rule change (table): formerly-capped intentional-N/A
+  recipes climb; nothing else moved.
+- Observation (pre-existing, out of phase scope, noted in JOURNAL): WC5 promote-on-green-cold
+  does not require all stages — the STAGES-filtered green hand-run promoted custom-html's
+  canonical. Filed as a JOURNAL note; flag if you want it as a finding.
