feat(async-intent): intent normalization at the execution boundary

MODEL OUTPUT = INTENT; RUNE CONTROLLER = EXECUTION SEMANTICS.

scripts/await_intent.py: deterministic resolver that derives canonical
op_type from stored normalized records / open PRs / git ancestry — model
supplied op_type and deadline_secs are recorded but NEVER used as policy
(git/Gitea truth outranks even legacy wait records). Sleep/check/poll
intent aimed at a known pending operation compiles to
ContinuePendingOperation; plain legitimate sleeps are untouched.
Timing provenance: USER_EXPLICIT/EXTERNAL_CONTRACT authoritative,
MODEL_INVENTED discarded. Ambiguity fails safe with structured
candidates. await_intent_cli.py = tool surface; compact JSONL
observability per normalization. await-operation.ts rewired to normalize
before dispatch (needs commit of harness tool separately).

+// 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.

+The model may express continuation intent in any quality — `await_operation

+"sleep 300 then check CI", "poll until done". When a matching

+  GOVERNED_OPERATION_POLICY  -> authoritative, retained
+  MODEL_INVENTED             -> non-authoritative, ignored

+(rune.event_wait) and git/Gitea state. The canonical continuation remains

+
+    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
+    ROLLED_BACK_REVERTED     switched, health red, prior current restored

+# 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)
+- Runtime loaded: confirmed via log (service=plugin event-wait-guard loaded)
+
+## Mandatory gate accounting
+- 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.

+# Rune Memory T0 — As-Is Memory Inventory Report
+
+*Prepared for external review. Self-contained: no prior context assumed.*
+
+---
+
+## 1. What this is
+
+An archaeology report on the memory system of **Rune** — a self-hosted AI coding assistant / personal agent running on Linux (repo: private Gitea, deployed generations under `/mnt/workdrive/rune-code`, canonical worktree `/mnt/workdrive/issue161-harness`).
+
+Rune just completed a long Scaffolding V1 programme (tranches T21.4/T21.5, accepted 2026-09-17 with 17/17 gates, deployed release v0.83.3). The first post-V1 phase is **Memory**. Its first tranche, **Memory T0**, was deliberately read-mostly: establish what memory machinery *actually exists today* before designing anything new.
+
+Central rule of T0: never collapse `EXISTS IN SOURCE ≠ WIRED ≠ RUNTIME REACHABLE ≠ ACTUALLY USED ≠ CANONICAL AUTHORITY`.
+
+**Verdict: MEMORY_T0_COMPLETE** — 17/17 gates PASS, `can_accept() = true`, merged as PR #333. Artifacts: `store/scaffold/memory_t0_gates.json` (gate object) and `store/scaffold/memory_t0_asis_map.json` (central map).
+
+---
+
+## 2. What Rune actually has today (the short answer)
+
+One canonical experiential store, one derived knowledge file, several dormant subsystems, one harness-native duplicate, and a set of adjacent non-memory stores that are correctly separated.
+
+### The canonical store
+
+`~/.config/opencode/memory/store/memory.db` — 456.8 MB SQLite with **two retrieval engines side by side**:
+
+- **Dense**: sqlite-vec, 256-dim Matryoshka-truncated embeddings via local Ollama (`nomic-embed-text`), content-hash cached.
+- **Lexical**: FTS5/BM25.
+
+`recall()` fuses both with reciprocal-rank fusion, applies a **0.42 relevance floor** (below it: abstain rather than inject distractors), supports query expansion via a lexicon, type targeting, and QPP-based abstention.
+
+**Contents**: 899 entries (812 active / 57 superseded / 25 inactive / 5 archived), 118,210 chunks, 5,732 documents, 1,149 associative links, 337 use-history rows. Warm neurons are stored as `kind='neuron'` rows (195) in the same DB — a previous file-based system (`.pasture` markdown files) was migrated and retired.
+
+**Supersession is real and receipted.** A dedupe policy gate sits on writes: similar new content either touches the existing row (`duplicate`), or — if longer/stronger — **supersedes** it (old row marked `status='superseded'`, `valid_until=now`, embedding nulled; history retained). Receipt ledger: 1,465 decisions (41 created / 1,306 duplicates / 118 superseded). Every row carries `source`, `method`, `confidence`, `temperature`, timestamps.
+
+### Derived knowledge
+
+`~/.rune/consolidation/knowledge.json` — 7,965 consolidated items (source-attributed: 7,207 from the store, 583 from abstraction, 165 from neurons, 10 from graph), actively growing (675 new in September). Read back into context via one of the selector's six sources. Whole-file rewrite per consolidation; rebuildable.
+
+### Dormant subsystems (exist, wired for read, no live writer)
+
+- **graph.sqlite** — a well-designed bi-temporal concept knowledge graph (typed nodes, `valid_from`/`valid_until` + `learned_at` edge semantics, supersession columns). 281 edges, **272 superseded**, last write 2026-08-26. The write path is a CLI; nothing in the live runtime feeds it. The read path (selector `graphs` source) queries a graph that hasn't been fed in three weeks.
+- **shards** — 131 topic-partition DB files containing **10 rows total** (one-row topic placeholders); typed queries bypass shards by policy. Effectively retired-in-place.
+- **temporal.db** — 3 facts, no importer in the repo's `src/rune` at all (harness-script-era relic).
+- **warm/memory.db** — 0 bytes; dead path.
+
+### Adjacent systems (correctly *not* memory)
+
+Task state (durable task repo + orchestration), Spine/Project Scaffold/Project Registry (structural truth), capability/behaviour ledgers (governance), the W/R event-wait bridge (task continuation), `behavior.db` (corrections/habits — borderline, near-empty). T0 verified no experiential facts live in structural stores and no structural facts in memory stores.
+
+### The duplicate-authority surface (the big architectural question)
+
+The **MiMoCode harness itself** (the VSCode-like agent harness Rune runs inside) maintains its own memory: `mimocode.db` (1.2 GB — 651 sessions, 98,692 messages, 773,595 parts, plus its own FTS) and `~/.local/share/mimocode/memory` (4.3 MB of markdown). Two systems remember the same operational life. T0 flagged this as the primary authority-boundary question for future design — nothing was reconciled.
+
+A second, smaller drift risk: the repo module `src/rune/memory_store.py` and the harness copy `~/.config/opencode/scripts/memory_store.py` are currently aligned, but the **harness plugin executes the scripts copy** while the TUI imports the repo module. Same code today, two deployment paths.
+
+---
+
+## 3. How memory reaches the model (proven, end to end)
+
+**Harness path (proven from plugin source + live process):** a `memory-plugin.ts` runs per turn:
+1. **Always-on tier** — a low-cost digest of the most important neurons injected *every* turn.
+2. **Keyword tier** — `warm_router.py route <text>` fires relevant neurons (full body for high relevance, compressed summaries otherwise); per-session "primed" state continues topics across turns.
+3. **Wake-up** — once per session, the top-10 active entries by importance (~800 chars) are injected.
+4. **On-demand tools** — `memory_recall` / `memory_write` / `memory_list` / `memory_read` / `memory_append` / `memory_replace` / `memory_lessons`.
+5. On session idle, a sleep sub-agent is launched (once per hour guard).
+
+**TUI/operator path (proven from source):** `rune_operator.send_task` → `ContextBroker.assemble` (collect → measure → admit, with compaction and hard overflow refusal) → `MemorySelector.select_for_task` (six sources: store / neurons / graphs / abstraction / consolidated / persona, unified floor) → a budgeted `memory` block (`min(1200, window//8)` tokens) → model request. Zero candidates = recorded abstention, never filler.
+
+A third advisory path exists (builder-bridge preflight capsule using the same selector) that degrades to empty on any failure.
+
+**The T21.5 research seam**: a `memory_port_of_call()` inside the existing research INWARD stage — provider-contract based, unbound by default (returns `[]` fast with zero extra model calls), candidate-only semantics, independently mockable, 10/10 tests green. Verified as safe to preserve as-is.
+
+---
+
+## 4. Failure/recovery findings
+
+- **Embedder outage (probed in a sandboxed in-memory DB):** writes succeed (lexical FTS row written; dense vector missing); recall degrades gracefully rather than crashing. The system fails soft.
+- **Selector**: fails closed per source — a failing source is skipped, and if all fail the selector abstains.
+- **Rebuildable**: FTS indexes, embeddings, knowledge.json, cache. **Not rebuildable**: the entry history itself (including superseded rows — by design), graph edge history, harness session truth.
+- **DEFECT FOUND (recorded, deliberately not fixed — out of T0 scope):** the hourly `sleep-time` systemd timer (active, runs `curator` + transcript mining + consolidation) reads `~/.local/share/opencode/opencode.db` — a **stale database from a defunct harness, 30.7 days old** — instead of the live `~/.local/share/mimocode/mimocode.db`. Every run logs "No sessions found". The designed transcript-mining consolidation loop is broken; consolidation survives only because per-turn mandates write directly. This is the first concrete fix candidate for the Memory build phase.
+
+---
+
+## 5. Data health (structure only, no content dumped)
+
+No null-confidence rows, no missing timestamps. Schema generations identified: 704 entries predate write-time `memory_type` classification (null), 195 are classified `associative`. Shards/`warm_state.json`/temporal are residue. 121 of 131 shard files are empty. The oldest live data is 2026-08-12; the newest is the day of the audit. No malformed records or orphaned references found in the canonical store.
+
+---
+
+## 6. Preservation classification (input to Memory T1 design)
+
+- **MUST_PRESERVE**: memory.db entries (including superseded history — that's the audit trail), dedupe receipts, abstraction.db facts, graph edge history, harness session truth.
+- **LIKELY_PRESERVE**: knowledge.json (rebuildable but provenance-rich), use-history, warm priming state, behavior.db.
+- **REBUILDABLE**: cache, FTS, embeddings, knowledge.json, shards.
+- **LEGACY_BUT_UNIQUE**: temporal.db's 3 facts (inspect before retiring); .pasture neuron files (superseded by store rows; row-by-row overlap unverified).
+
+---
+
+## 7. Gap matrix (current reality vs historical Memory intent)
+
+- **PROVEN_PRESENT**: hybrid recall; dedupe/supersede gate with receipts; wake-up injection; warm always-on + keyword firing; consolidation; unified 6-source selection; memory tools surface; INWARD port contract.
+- **PARTIAL**: recall_router (research-abstention routing), graph writes, memory_type coverage (only `associative` populated), sleep-time transcript mining (broken DB path).
+- **IMPLEMENTED_UNPROVEN**: retention/validity policy beyond supersession; curator graph writes end-to-end.
+- **DORMANT**: shards, temporal.db, warm/memory.db, .pasture.
+- **ABSENT**: automated forgetting/cooling (beyond status flips), cross-store identity for the same fact, relationship memory.
+- **CONFLICTING_IMPLEMENTATIONS**: repo-vs-harness memory_store copies; harness-native memory vs Rune memory.
+- **UNKNOWN**: none remaining (T0 exit criterion).
+
+---
+
+## 8. What was *not* done (by design)
+
+No future architecture designed. No data migrated, repaired, or deleted. No runtime guard or behavior changed. Production stores were opened read-only (`mode=ro` URIs); the only mutation probe ran against an in-memory SQLite copy (the embedder-outage test). Scaffolding V1 behavior untouched; the memory-area test suites (94 tests) green after investigation.
+
+---
+
+## 9. Recommended next phase (Memory T1 — design, not build)
+
+1. Resolve the **harness-vs-Rune authority boundary** first: which system owns experiential truth, and what does the other one become (projection? source? separate scope?).
+2. Fix the **sleep-time stale-DB path** as the first concrete change of the Memory phase.
+3. Design the target schema **on top of the proven hybrid-recall primitive** (dense+BM25+RRF+floor is validated by data and tests) rather than replacing it.
+4. Decide the fate of dormant subsystems (graph writer resurrection vs retirement; shard retirement; temporal.db inspection) with the preservation register in hand.
+5. Close the repo-vs-harness code-copy drift risk.
+
+---
+
+*Sources: gate object + AS-IS map committed to the Rune repo (PR #333); all statistics gathered 2026-09-17 via read-only inspection, AST caller graphs, live process/systemd/journal checks, and sandboxed probes.*
