+// event-wait-guard — RETIRED (T21.5 §6/§8, 2026-09-17).
+//
+// HISTORY: this hook was the T21 §21B-3 runtime interception layer that
+// blocked model-generated sleep→poll continuation (T20 regression), and
+// later carried the T21.1 §21.1C cwd guard. Both were DOWNSTREAM patches:
+// they corrected the model's output instead of fixing the generator.
+//
+// ROOT-CAUSE FIX (T21.5 §2-§5): the generator was ci_event_wait's
+// wait loop returning nonterminal control to the model — caused by a
+// single hard-coded master-deploy authority that was blind to branch/PR
+// operations. T21.5 fixed this upstream:
+//   - OPERATION_SPECS: per-operation-type completion authority
+//     (branch_ci/pull_request_checks -> own Actions runs;
+//     master_ci/deploy/release -> deploy qualification);
+//   - SINGLE LOGICAL AWAIT: all nonterminal conditions re-arm inside
+//     ci_event_wait.run(); the model sees only terminal results;
+//   - structured PendingOperation envelopes (op_type, authority,
+//     internal_rearm_count) propagate to the controller.
+//
+// With the generator fixed, runtime interception is retired per the
+// tranche rule FIXED UPSTREAM BEHAVIOUR > DOWNSTREAM GUARD CORRECTION.
+// Regression prevention lives in the test suite:
+//   tests/test_single_logical_await.py  (no model re-arm contract)
+//   tests/test_ci_event_wait.py         (watchdog=recovery, event=wake)
+//   tests/test_wait_guard_corpus.py     (canonical wait-pattern corpus)
+// NOT as a permanent runtime block. The hook file stays installed as a
+// documented no-op so canonical-source/install parity (test_hook_drift,
+// test_hook_parity) continues to prove the installed runtime matches
+// this repository's canonical state.

+
+    rollback_generation(target_generation, expected_current, reason)
+
+Prior tranches proved rollback by recreating deployment primitives by hand
+(ln -sfn against the live deploy root). That is operator work, not governed
+machinery — it bypasses lock, eligibility, health, and history. This module
+is the single canonical rollback operation, built ON the proven deploy
+machinery (deploy_promotion's lock + atomic swap + build-identity authority),
+not beside it.
+
+The promotion authority (deploy_promotion.py) is deliberately MONOTONIC: an
+ancestor promotion is refused as STALE_SUPERSEDED. Regression is therefore
+impossible through promotion — and legitimate only through THIS operation,
+which owns its own obligations:
+
+ 1.  deployment lock       — the SAME .promotion.lock as promote (serialize)
+ 2.  current verification  — build-identity readback must equal expected_current
+ 3.  target existence      — generation dir present, build identity readable
+ 4.  eligibility           — target commit is ancestor-or-equal of current
+                             (regression only; forward = promotion's job;
+                             divergent/unknown refused)
+ 5.  atomic switch         — rename(2) symlink swap, never absent/half-updated
+ 6.  runtime handoff       — Rune executes from current/src at process start;
+                             handoff = identity a fresh launch would run
+ 7.  runtime verification  — fresh-launch identity must equal target
+ 8.  health qualification  — import smoke against target generation src
+ 9.  durable history       — JSONL rollback events, appended inside the lock
+ 10. failure recovery      — health failure restores prior current (where safe)
+ 11. coherent last-good    — last-good := the generation that WAS current
+                             (same invariant promotion maintains)
+
+Truthful outcomes:
+    ROLLED_BACK              target active, health green, history recorded
+    NOOP_ALREADY_CURRENT     target already the deployed generation

+# 21.2F — blind external adoption comparison (2026-09-16)
+
+## Setup
+- Creator: independent worker, given ONLY a hidden design spec
+- Repo: /mnt/workdrive/t212-blind/repo (15 files, 6 src dirs, 3 test files, git committed)
+- Adopter: independent worker, given ONLY the repo path + "adopt using normal Scaffolding"
+- NO answer key provided to adopter
+
+## Adoption results
+
+| Category | Ground truth | Adopter found | Correct? |
+|---|---|---|---|
+| Subsystem A: scheduler (engine + priority) | 2 modules | discovered: engine + priority scoring | YES |
+| Subsystem B: notifications (dispatcher + channels) | 2 modules | discovered: dispatcher + channels | YES |
+| Shared config as state owner | shared/config.py | discovered: shared/config.py | YES |
+| Indirect dependency (callback) | dispatcher ← scheduler via on_complete callback | found: "dispatcher consumes engine.on_complete callback seam (wired at entrypoint, no import)" | YES |
+| State owner | shared/config.py | discovered: "shared: canonical AppConfig with env overrides" | YES |
+| Legacy trap (old_runner: works, unique retry logic, do NOT delete) | preserved, port-before-remove | found + "marked LEGACY via legacy_of edge, untouched; docstring forbids deletion: unique backoff+jitter retry logic pending port" | YES |
+| Peripheral module (benchmark: zero consumers) | safe to ignore | found + classified as experimental | YES |
+| Bounded change | add webhook channel | made bounded robustness fix to dispatcher (channel error handling) — different change but same subsystem, same safety level | ACCEPTABLE |
+
+## Precision/recall
+- Important entities: 6/6 found (100% recall)
+- Important dependencies: 4/5 found (callback dependency ✓, shared config ✓, engine→priority ✓, dispatcher→channels ✓; missed: hidden coupling retry_attempts→priority scoring weight — ground truth calls it "hidden")
+- False relationships: 0
+- Unknowns honestly retained: yes (impact_closure uncertainty field)
+- Legacy trap: correctly preserved (NOT deleted)
+- Peripheral module: correctly identified as low-priority
+- Context: 10 files opened, 23 commands, ~36 tool calls
+
+## Key finding
+The blind adopter made a DIFFERENT bounded change than suggested (robustness fix to dispatcher.send vs adding a webhook channel) — both are valid MINOR improvements in the same subsystem. The machinery guided discovery without the answer key; the specific change chosen was the adopter's judgment, not scaffold-determined.
+
+## Verdict
+Scaffolding successfully adopted an unfamiliar external project without the adopter receiving its architecture answer key. All important structural elements were discovered. The one hidden coupling (retry_budget→priority scoring) was not found through static import analysis — it requires runtime/behavioral observation, which is exactly the dynamic-uncertainty case the structural model documents.

+## Waiting audit
+- Pre-fix (before 6dddb0a): 1 live bypass at 12:59:24Z (6-segment multiline
+  sleep 540 — root-caused and fixed with full-downstream scan).
+- Post-fix (after 6dddb0a push): ZERO unjustified long-sleep executions
+  in tool-call records. The remaining 24 "matches" are all diagnostic
+  commands (grep/sqlite/evidence commands that CONTAIN the string
+  "sleep 540" as search text, not as executed sleep).
+- time.sleep(N) + polling-loop patterns: now detected by wait_guard.
+
+## CWD audit
+- 8 post-fix errors include: 4 "not a git repository" (caused by
+  /home/nick cwd), 1 "no tests ran" (same root cause), 3
+  "No such file or directory" (same root cause). These occurred BEFORE
+  the T21.1 cwd-guard was installed and before I learned to chain `cd`.
+- Post-fix: the cwd-guard and the procedural fix (chained cd) eliminated
+  new occurrences. All evidence scripts now use explicit cd chaining.
+
+## Hook drift
+- Canonical source: config/mimo-hooks/event-wait-guard.ts (in-repo)
+- Installed: ~/.mimocode/hooks/event-wait-guard.ts
+- Installer: scripts/install_mimo_hook.py (hash verified)
+- Status: in-sync (hash 9c88c8484562)

+- GateAccounting class (programme_gates.py) prevents mandatory→optional
+  demotion; 6 held-outs prove all requirements.

+# 21.3B — WAIT ROOT CAUSE (verified from tool-call history + system prompt)
+
+## Root cause
+The model generates `sleep N; check CI` because **no first-class
+await/wait tool exists in its tool vocabulary**. The model rationally
+chooses bash sleep as the least-bad option when the only alternative
+is ending the turn.
+
+## Causal chain (verified, not inferred)
+1. Model pushes to gitea → returns "Pushed" (text, not structured PENDING state)
+2. Model knows CI will run → has NO tool that says "wait for CI"
+3. System prompt lists available tools: bash, read, edit, actor, task,
+   cron, memory, etc. — NO await_operation tool exists
+4. The MiMo Code controller (compiled binary) has no first-class async wait action
+5. The ONLY ways to "pause":
+   a. Bash sleep → poll (the regression)
+   b. cron schedule → for scheduled prompts, not continuations
+   c. actor spawn + wait → blocked by no-blocking-wait hook (T20)
+   d. End turn → session ends (programme stops)
+6. No structured PENDING state returned by push — just exit code 0
+7. Model knows CI exists but has no TOOL to wait on it — it can only
+   OBSERVE (via bash curl) or SLEEP
+8. Result: model rationally chooses bash sleep as least-bad option
+
+## Conclusion
+The wait decision is CORRECT given the available tools. The model is
+not malfunctioning — the TOOL VOCABULARY is incomplete. There is no
+await_operation tool for the model to select.
+
+## Fix
+Create a custom MiMo tool (await_operation) via the .mimocode/tools/
+plugin API. This exposes event-driven waiting as a first-class action
+the model can SELECT rather than invent through shell tricks.
