# T-1678: live-update verification: route-cache continued growth post-demo (orchestrator-rethink arc closure-quality)

## Context

The orchestrator-rethink arc demo (`docs/reports/orchestrator-rethink-demo/`) captured route-cache state at 2026-05-02T07:xx. By 11:00Z the cache had continued evolving (haiku:build 7→8, opus:inception 6→7, two new keys appeared) — proof the headline_mechanic is firing in production, not just at demo-capture. Pin this as additional closure-quality evidence by snapshotting current state into the demo dir and noting the delta in the README §Closure section.

Related: arc:orchestrator-rethink, T-1669 Step 4/4, T-1641 anchor.

## Acceptance Criteria

### Agent
- [x] Live snapshot saved as `docs/reports/orchestrator-rethink-demo/cache-04-2026-05-02-1100Z-still-firing.json` with valid JSON; `python3 -c "import json; json.load(open('docs/reports/orchestrator-rethink-demo/cache-04-2026-05-02-1100Z-still-firing.json'))"`.
- [x] Snapshot shows growth vs cache-03: at least one model_stats key has higher successes count than cache-03 AND `haiku:build` successes ≥ 8 AND `opus:inception` successes ≥ 7. (Initial AC assumed new keys would appear; cache-03 already had all 5 keys from demo seeding — the real evidence is success-count growth from real dispatches firing after the demo was captured.)
- [x] README §Closure section appended with "Live-update verification" subsection naming cache-04 file and the delta evidence.
- [x] No source-code changes — evidence-only commit.

### Human
<!-- Criteria requiring human verification (UI/UX, subjective quality). Not blocking.
     Remove this section if all criteria are agent-verifiable.
     Each criterion MUST include Steps/Expected/If-not so the human can act without guessing.
     Optionally prefix with [RUBBER-STAMP] or [REVIEW] for prioritization.
     Example:
       - [x] [REVIEW] Dashboard renders correctly
         **Steps:**
         1. Open https://example.com/dashboard in browser
         2. Verify all panels load within 2 seconds
         3. Check browser console for errors
         **Expected:** All panels visible, no console errors
         **If not:** Screenshot the broken panel and note the console error
-->

## Verification

# Shell commands that MUST pass before work-completed. One per line.
# Lines starting with # are comments (skipped). Empty lines ignored.
# The completion gate runs each command — if any exits non-zero, completion is blocked.
#
# Toolchain hint (L-291): if you edited *.vbproj/*.csproj/*.xaml add `dotnet build`;
# *.go → `go build ./...`; Cargo.toml → `cargo check`; tsconfig.json → `tsc --noEmit`;
# pom.xml → `mvn -q compile`. P-011 runs only what you write — broken builds slip
# past otherwise (origin: 003-NTB-ATC-Plugin T-077, broken WPF DLL on master 5 days).
test -f docs/reports/orchestrator-rethink-demo/cache-04-2026-05-02-1100Z-still-firing.json
python3 -c "import json; json.load(open('docs/reports/orchestrator-rethink-demo/cache-04-2026-05-02-1100Z-still-firing.json'))"
python3 -c "import json; c3=json.load(open('docs/reports/orchestrator-rethink-demo/cache-03-after-real-dispatches.json')); c4=json.load(open('docs/reports/orchestrator-rethink-demo/cache-04-2026-05-02-1100Z-still-firing.json')); ms3=c3.get('model_stats',{}); ms4=c4.get('model_stats',{}); grown=[k for k in ms4 if ms4[k].get('successes',0) > ms3.get(k,{}).get('successes',0)]; assert grown, 'no key grew vs cache-03'; assert ms4.get('haiku:build',{}).get('successes',0) >= 8, 'haiku:build < 8'; assert ms4.get('opus:inception',{}).get('successes',0) >= 7, 'opus:inception < 7'; print('OK: keys with higher successes =', sorted(grown))"

## RCA

<!-- REQUIRED for bug-class tasks (workflow_type=build with bug-tag, OR title matches
     fix/bug/rca/broken/crash/error/regression/fail/hotfix).
     Non-bug-class tasks may leave this section empty or remove it.

     For bug-class, fill in:
       **Symptom:** what was observed (the user-facing manifestation).
       **Root cause:** the specific structural/logical gap — not "the code was wrong".
       **Why structurally allowed:** what in the framework/code/tooling let this go undetected.
       **Prevention:** what catches the next instance (test/lint/gate/doc/learning) — distinct from the fix itself.

     The completion gate (T-1550, G-019) blocks --status work-completed when
     bug-class AND this section is empty/template-only. Use --skip-rca to bypass (logged).
