**Indexing:** prefer `runFullWorkspaceIndex` -> publish repository state. If that has not run, fall back to `buildWorkspaceSnapshot` (honest fingerprint: indexes unavailable).
+**Index pipeline health:** call `readIndexPipelineHealth({ workspaceRoot })` (or CLI `mitii index --status`) to see which pipeline is ready vs failed: Code Index, Text FTS5, Embeddings, Graph/Map, Tree-sitter, and native sqlite / LanceDB / ONNX. Overall is `ready`, `lexical_only`, `running`, `failed`, or `missing`.
+
**Semantic retrieval** is off unless the host passes `semanticIndex.enabled` (and a ready embedding profile). When disabled, repository context logs `semantic_index_disabled` and falls back to path-based discovery.
**Memory** persists under `.mitii/memory/facts.json` when `createWorkspaceMemoryStore` is injected. The adapter accepts validated facts and returns validated facts through `query`/`list`; `delete` returns `{ id, deleted, message }`. Mutations read and validate the stored envelope and every row before replacing the file using a same-directory temporary file and rename. A per-instance mutation queue serializes calls through one adapter object; exclusive directory locks coordinate separate instances and processes on the same facts file. `transact` applies a scoped decision and writes its full change set under that same lock.

- `StructuralShadowGrantAuthorizer` can evaluate a Cedar-shaped structural grant in parallel with normal validation.
- Mutation batches enforce `maxPatchesPerCall`, `maxUniqueFilesPerCall`, and `maxPatchPayloadCharacters`. Exceeding those caps fails preflight with `mutation_budget_exceeded` (not a generic `limit_exceeded`).
- Mutation tools (`apply_patch`, delete, move) authorize against `grant.mutationPathScopes` when present; discovery tools keep `grant.pathScopes`.
-- `apply_patch` defaults to exact `oldText` matching (no regex). Optional `replaceAll: true` replaces every exact occurrence in that file; empty `oldText` still means create or full-file replace and rejects `replaceAll`. Optional `fuzzyMatch=true` (or host `fuzzyMatchDefault`) enables bounded recovery when exact oldText is missing (trim / indent / ±5 line window); ambiguous fuzzy hits return `patch_fuzzy_ambiguous`. Distinct reason codes describe why a hunk failed: `old_text_not_found`, `old_text_ambiguous`, `patch_fuzzy_ambiguous`, `patch_target_missing`, `patch_hash_mismatch`, `identical_old_and_new`, `patch_syntax_invalid`. Retryable conflicts, including no-op `identical_old_and_new`, attach clipped `currentContent` in the tool result. `patch_conflict` remains as a legacy umbrella for older hosts.

- Preflight coerces common model mis-encodings for `apply_patch`: a flat `{ path, oldText, newText }` object is wrapped into `{ patches: [...] }`, and a JSON-string `patches` value is parsed into an array before schema validation.
- Preflight also normalizes common discovery/command aliases via
`normalizeCommonToolArguments`: `search_files.pattern` → `query`,

## Technical Details
+- **Grant profiles:** `BuildToolGrant` selects exactly one profile from mode×route — `none` | `network_only` | `readonly` | `agent_execute`. Ask/plan never get `agent_execute`. Only **agent + route `execute`** grants `apply_patch` (and other mutation tools). Profile is emitted as `grant_profile_*` reason codes for audit.
+- **Authority ladder:** Intake (mode / turnKind / artifacts) → Request Understanding Officer ballot (LLM ≥0.70; TurnKind clears soft clarify) → Decision Policy authorizes route + grant. Soft `looksLike*` heuristics lose to a trusted write ballot; **vitest/jest failure pastes** also yield to accepted act+mutation at ≥0.60. Hard plan-only / hard read-only still win.
+- **Facts-first default:** When understanding is high-confidence (≥0.70 + margin, accepted, no clarify), route resolution prefers the ballot over classic heuristics. Set `policyFactsFirst: false` only as a kill-switch. Continuation turns (`steer` / `follow_up` / `continue` / `recover`) emit `turn_continuation` and do not re-suspend on soft Task Analyzer clarity alone.
+- **Officer plan-then-finish:** RU `taskSize` / `planningHint` (`medium`/`short` → internal; `large`/`long` → visible when affordable) emit `officer_task_size_plan` on agent execute — still **route execute**, not plan-only.
- Ask and plan modes cannot receive write grants.
- Optional `userSafetyRules` (from `.mitii/safety.json`) may only tighten a grant after mode seals and injection clamp — never widen.
- Agent (and ask) "run the tests / can you test" requests route to `diagnose` with `run_readonly_command`. Implement/fix phrasing still wins over a mention of running tests.
-- Agent clarify gate: clear "implement/fix …" asks still execute when understanding only has soft ambiguity. Material forks (diagnose vs mutation alternatives, investigate-vs-fix ambiguity questions, or `needsClarification` with confidence below 0.75) route to `clarify` instead of guessing.
+- Agent clarify gate: clear "implement/fix …" asks still execute when understanding only has soft ambiguity. Material forks (diagnose vs mutation alternatives, investigate-vs-fix ambiguity questions, or `needsClarification` with confidence below 0.75) route to `clarify` instead of guessing. On continuation turns, material heuristic↔ballot conflict prefers safe `diagnose` over re-clarify.
- Intent ballot: rule↔LLM agreement grows confidence; on conflict, LLM ≥ 0.70 wins the route (e.g. LLM `act` over rule `question`) unless `needsClarification` is set. The same ≥0.70 write ballot also wins soft Decision Policy keyword hits on follow-ups (soft read-only, soft "make a plan", pasted dumps, verification/symptom when they would steal the route). Hard overrides still win: `plan only`, "no code/file changes".
- Soft workspace symptoms (stuck loading / hang with server or localhost) route to `diagnose` in Agent mode — never tool-less `direct_answer`.
- Injection scanning never broadens authority.

## What This Module Does
- Validates the incoming request shape.
-- Requires meaningful content through a message or referenced artifacts.
-- Normalizes mode, origin, workspace scope, referenced artifacts, and correlation metadata.
+- Requires meaningful content through a message, referenced artifacts, or a meta command.
+- Sanitizes user text and classifies leading slash commands (mode + meta lifecycle).
+- Extracts `@path` mentions into `referencedArtifacts` (paths only — no content load).
+- Normalizes image attachments (mime allowlist + size caps).
+- Normalizes mode, origin, turn kind, workspace scope, referenced artifacts, and correlation metadata.
- Assigns request ids and timestamps through injected ports.
- Produces the stable envelope consumed by Request Understanding and Decision Policy.

+## Intake Stages (inject order)
+
+1. Sanitize
+2. Command classify (`/stop|/new|/plan|…`)
+3. Mention extract → `referencedArtifacts`
+4. Attachment normalize
+5. Mode resolve (slash overrides host when `/ask|/plan|/agent`)
+6. Validate + build envelope
+
+Meta commands with non-agent lifecycle set `shortCircuitMeta` via `intakeDetailed` so the engine can exit before pin/understand.
+
+Engine `session-control` then **handles** classified commands:
+- `/compact` — force-compacts `start.conversation` and returns `result.sessionControl.compactedConversation` for the host to persist
+- `/new` `/clear` — returns `sessionAction` so the host clears transcript storage
+- `/stop` — cancelled run
+- `/help` `/status` `/resume` — side-channel answers (host owns resume storage)
+
+## Host Contract (selection / open tabs)
+
+Intake never calls IDE APIs. Hosts must pre-fill structured refs on `CreateUserRequestInput`:
+
+| Host signal | Envelope field |
+|-------------|----------------|
+| Active editor selection | `referencedArtifacts[]` with `kind: "selection"`, `path`, `startLine`, `endLine` |
+| Explicit @-picker / drag files | `referencedArtifacts[]` with `kind: "file"` or `"folder"` |
+| Open / visible tabs (optional) | additional `kind: "file"` refs (cap with envelope limits) |
+| Pasted / attached images | `attachments[]` (mime allowlist + size caps) |
+| Mid-run steer / follow-up | `turnKind: "steer" \| "follow_up" \| "continue"` (+ optional `parentRequestId`) |
+| Session new/resume | `sessionAction` — classify only; host owns storage |
+
+Intake will also parse `@path` and whole-message bare paths into artifacts, but **selection ranges and open-tab sets are host-only**.
+
## Types And Contracts
- `CreateUserRequestInput`: boundary input with `sessionId`, `mode`, `userMessage`, optional `requestId`, `origin`, `referencedArtifacts`, `workspace`, and `correlation`.

Request Understanding converts a normalized `UserRequestEnvelope` into structured task evidence. It tells policy and planning what the user appears to want, but it does not grant authority.
+**Authority model (Evidence → Officer):** Investigators (rules, size draft, artifacts, attachments meta, MCP ids, skill tags, history digest) build an evidence pack. The **Officer LLM** is the sole judge of interaction/task intent (except explicit slash / exact intent). SuperIntent no longer lets strong heuristics override the LLM primary. Decision Policy issues the warrant later — it must not re-investigate.
+
## What This Module Does
-- Extracts the primary user message from the envelope.
-- Classifies task and interaction intent.
-- Resolves a Super Intent result with confidence and clarification signals.
-- Runs Task Analyzer to derive scope, complexity, risk, clarity, targets, constraints, and requested outcomes.
-- Recommends whether repository discovery, planning, verification, or clarification may be needed.
+- Builds an investigator **evidence pack** before classification.
+- Runs heuristic rules as **advisory priors** (not silent winners).
+- Classifies task and interaction intent via the Officer LLM.
+- Resolves a thin Super Intent result (coerce, mode remaps, turnKind, diagnostics).
+- Runs Task Analyzer for scope/complexity/risk/clarity plus **`taskSize`** / **`planningHint`**.
+- Mode-shaped clarification guidance in the Officer prompt (ask ≠ agent).

## Types And Contracts
- `RequestUnderstandingPipelineInput`: the `UserRequestEnvelope`.
-- `RequestUnderstandingResult`: `{ intent, taskAnalysis }`.
-- `intent`: Super Intent result with status, classification, scores, confidence margin, clarification recommendation, and diagnostics.
-- `TaskAnalysis`: scope, complexity, risk, clarity, targets, constraints, requested outcomes, recommendations, estimated file impact, signals, and confidence.
+- `RequestUnderstandingResult`: `{ intent, taskAnalysis, evidence? }`.
+- `UnderstandingEvidencePack`: mode, turnKind, message stats, artifacts, images meta, MCP, skill tags, rulePriors, sizeDraft, optional history.
+- `intent`: Super Intent result with status, classification, scores, confidence margin, clarification, diagnostics (`officerFallback` when LLM failed).
+- `TaskAnalysis`: existing dimensions + `taskSize` (`small|medium|large`) + `planningHint` (`none|short|medium|long`).
## Technical Details
-- The public facade method is `RequestUnderstandingPipeline.understand`.
-- Rule classifiers provide deterministic intent signals.
-- Optional LLM classification can enrich the intent result.
-- Task analysis focuses on dimensions, not hard-coded task templates.
+- Facade: `RequestUnderstandingPipeline.understand` (options may include `historyDigest`, `requiredMcpServerIds`, diagnostics).
+- Explicit `/bugfix` (confidence 1) skips the Officer LLM.
+- Rule↔LLM task conflict → **LLM primary wins**; agreement can still boost confidence.
+- `taskSize` / `planningHint` prefer Officer `taskHints`, else sizeDraft, else complexity map.
- Recommendations are advisory; Decision Policy decides route and grants.
