+
+Master is at `5cae33a`, pushed, tree clean apart from this file. Working on master
+raw by the owner's call: no branch, `--no-verify` on every commit with the reason
+in the body.
+
+## Landed this session
+
+Twelve commits pushed. Nine were the previous session's tree, already described in
+the commit log. Three are new:
+
+- `78a9c61` `docs/spec.md`, 51 capabilities with a DoD each.
+- `02e3d27` `docs/roadmap.md`, seven milestones, plus both pointer rows in `CLAUDE.md`.
+- `5cae33a` honesty split into three milestones, five capabilities deferred past v1.
+
+**Read `docs/spec.md` and `docs/roadmap.md` before anything else.** Every decision
+from this session is in them. This file holds only what they do not.
+
+## The two documents
+
+`docs/spec.md` is the union of the 39 audited rows
+(`docs/evals/2026-08-13-capability-audit.md`) and the owner's 18-item v1 list.
+Twelve of his items had no audit row, so the file has 51 entries. Each entry
+carries three parts. State is a reference to the living doc that owns it. DoD is
+a plain list observable on the running box. Scenario names a file in
+`cmd/mavend/testdata/scenarios/`.
+
+`docs/roadmap.md` orders them into nine milestones. Honesty, then reach, then
+breadth. Not ordered by code work, because none of the four broken capabilities is
+a code defect.
+
+## Decided, do not re-ask
+
+- **v1 is a voice assistant, minimum viable.** Each DoD is written at
+  "voice-reachable and honest", not "feature-complete".
+- **Honesty splits into three.** M1 the turn path, M2 memory he cannot correct,
+  M3 step-up. M1 and M2 touch different code and owe different docs. Step-up is
+  configuration, not honesty, and sits before M4 because M4 is what first makes
+  acts real.
+- **Five capabilities deferred past v1** (owner's call, 2026-08-15): speaker
+  recognition, smart home, bluetooth control, model swap, self-update. Bluetooth
+  was on the v1 list and came off it. Their spec entries keep their DoD.
+- **A milestone closes its own doc gaps and writes its own scenarios.** Neither
+  becomes a milestone of its own. Otherwise the 17 missing docs and 46 missing
+  scenario files collect at the end.
+- **Learning means behavioral, not weights.** Stored outcomes only. No adapter, no
+  training set.
+- **Email and calendar need the product decision before deploying.** Both are
+  built and neither is in `docker-compose.yml`. That is M8.
+
+## Findings the spec pass produced
+
+- **Recurring reminders do not exist on the spoken path.** `store.Reminder` carries
+  `Cron` and `ipc.CreateReminder` takes one. `grep "Cron:" --include='*.go'`
+  outside tests returns only `internal/ipc/client.go`, `internal/ipc/storeapi.go`
+  and `cmd/mavend/tick_routines.go`, and the last is routines, a separate
+  mechanism. Pills, the dog, the vet and the kibble are unbuilt on top of finished
+  storage and delivery. This is M6.
+- **Seventeen capabilities have no living doc.** Memory is the worst cluster:
+  facts, notes and the digestion worker have no owning document at all.
+- **Webhooks barely exist.** The only one in the tree is
+  `internal/delivery/telegramsink/intake.go`, Telegram's own inbound hook.
+- **Command chaining does not exist.** The `chain` in `internal/router` is the
+  world chain and the source chain.
+- **Desk notifications are inbound only.** `ambient:notif` reads his desktop.
+  There is no outbound desk reach, and which direction he meant is undecided.
+- **Only 5 of 51 spec entries cite a scenario that exists.**
+
+## Not filed, and this is the risk
+
+Vikunja returned 503 across this session and the last, so **none of this has a
+task id**. The three commits above are tagged `V-719`, which is the
+reminder-cancellation task, not this work. Retag or file when Vikunja is back.
+
+Unfiled, listed again at the end of `docs/roadmap.md`:
+
+1. The capability audit itself, headed "unfiled".
+2. Remember-versus-query misroute, two of seven audit probes.
+3. The masculine reply on the wire, caught live while `CheckFeminine` passed.
+4. Recurring reminders having no caller.
+5. The seventeen capabilities with no living doc.
+6. The 46 scenario files the spec names and does not have.
+
+## Next
+
+Open a session on M1, which is three gate items on the turn path and owes no new
+doc. If Vikunja is up, file the six above first and give M1 a real id.
+
+One command still outstanding from the last session, cheap and unrelated:

+utterance
+  |
+  v
+Stage 0: Grammars (stagezero.go:24-91)
+  | 22 ordered regex/structural grammars. First match wins.
+  | Confidence = 1.0, Stage = 0. fillMatchedSlots runs.
+  | NO MATCH -> fall through
+  v
+Stage 0b: Routing Heads (heads.go, ONNX)
+  | 4 linear heads over mean-pooled e5-small: intent, destination, slot BIO, clarify
+  | Below headsThreshold (0.6) -> decline, cascade continues
+  | Intent head softmax -> Decision{Intent, Confidence, Source, Clarify}
+  | completeParsedSingleVerbFact can overrule clarify
+  | NO WIRE / ERROR / DECLINE -> fall through
+  v
+Stage 1a: LLM Router (llmrouter.go, Qwen3-1.7B via llama-server)
+  | GBNF grammar-constrained JSON output
+  | gateLLMDecision: thin confidence (0.3) for incomplete slots
+  | ERROR / PARSE FAIL / "unknown" -> fall through
+  v
+Stage 1: Nearest-Centroid Classifier (classifier.go)
+  | Cosine similarity over ONNX embeddings against seed centroids
+  | Best intent wins (ties broken by name)
+  v
+Stage 2: Slot Extraction (slots.go:55-91)
+  | Dispatch on intent: DateTimeParser (reminder), ActMatcher (act), FactParser (fact)
+  v
+Stage 3: Confidence Gate (router.go:244-248)
+  | Confidence < threshold (0.55) -> Clarify = true, Stage = 3

+| ActionCandidate | `router.Decision` + `actionHandlers` dispatch | No explicit ActionCandidate type; intent + slots + handler selection are implicit |

+| Post-execution verification | No explicit verification step after tool execution (success/failure is the extent) |
+
+---
+
+## F. Gaps Against the Proposed First-Stage Design
+
+### Proposed pipeline vs current reality
+
+| Proposed stage | Current state | Gap |
+|---------------|---------------|-----|
+| **NormalizedInput** | Raw `text string` everywhere | No normalization struct. Preprocessing is scattered: StripWakeToken in router, lowercase in matchers, trim in entry points |
+| **Deterministic fast-path** | Stage-0 grammars (22 rules) | EXISTS and is production-critical. However: grammars produce `Decision` directly, not a separate FastPathResult type. No schema validation on slots before returning |
+| **Learned routing** | Heads -> LLM -> Classifier cascade | EXISTS and complex. But: multiple confidence scales (stage-0=1.0, heads=softmax, LLM=1.0/0.3, classifier=cosine). No unified confidence model |
+| **RouteDecision** | `router.Decision` | EXISTS under another name. Carries Stage, Intent, Confidence, Slots, Clarify, Source. Could be wrapped/renamed |
+| **ActionCandidate** | Implicit in `router.Decision` + `actionHandlers` | Missing as explicit type. The decision arrives at applyAction and is dispatched by intent. No schema validation of slots before dispatch |
+| **Schema validation** | NONE | Slots are filled by extractors and used directly. No validation that e.g. reminder has both Text and Time before actionReminder runs |
+| **Confidence/risk policy** | Threshold gate (0.55) for routing; risk tiers for tools | No unified confidence policy. Routing confidence and tool risk are separate systems. No policy that says "if confidence < X, require confirmation for action" |
+| **Confirmation** | resolveConfirm with 3 pending slots | EXISTS for destructive tools, Hexis, and routines. Not applied to routing confidence (a low-confidence act just gets proposed, not confirmed) |
+| **Execution** | tool.Executor.Exec | EXISTS with MCP/HA/process dispatch. Well-structured. But: actionFact, actionReminder, actionNote bypass tool.Executor entirely (they call CoreAPI directly) |
+| **Post-execution verification** | Success/failure error handling in actionAct | Partially EXISTS. Tool execution returns (out, err). Error types are handled specifically. But: no structured verification step, no retry policy, no rollback |
+
+### Architectural problems identified
+
+1. **Fast paths that execute directly**: actionFact, actionReminder, actionNote call CoreAPI.WriteFact/CreateReminder/WriteNote directly from the action handler, bypassing tool.Executor. This means they skip the risk tier system, the confirm gate, and the allowlist. This is by design (facts/reminders are user-stated, not tool invocations) but means the "all actions through one pipeline" goal requires either wrapping these in tool-like abstractions or explicitly exempting them.
+
+2. **Multiple confidence scales**: Stage-0 = 1.0 (hardcode), heads = softmax float, LLM = 1.0 or 0.3 (thin), classifier = cosine similarity. These are not on the same scale and cannot be compared. The claim system (claim.Band) explicitly addresses this by making confidence ordinal (Band) rather than graded. The proposed design should preserve this insight.
+
+3. **Routing code that also performs tool selection**: actionAct at actions_act.go:29-33 runs the matcher inline when HasFn is false. The matcher is also the stage-2 ActMatcher. So tool selection happens both in the router (stage 2) and in the action handler (actionAct). The actionAct path is the fallback for LLM-routed acts where the verb didn't go through stage-0.
+
+4. **Implicit fallthrough**: The router cascade is explicitly designed as fallthrough (each stage may decline). The query source chain is also fallthrough (first claim wins). The confirm resolver chain is also fallthrough. This is a consistent pattern, not a bug, but means the "stage-to-stage" architecture must preserve explicit decline semantics.
+
+5. **Clarify bypasses action pipeline**: When dec.Clarify is true, applyAction returns "" immediately (voice.go:497-499). The clarifier can also call hexisBeforeClarify (voice.go:446) to try Hexis before asking, which is a hidden action path that runs before the normal action dispatch.
+
+6. **No schema validation**: Slots filled by stage-2 extraction or stage-0 grammars are used directly by action handlers. actionReminder (actions_reminder.go) checks HasTime itself. actionFact checks HasKey. But there is no shared validation layer; each handler does its own checks.
+
+7. **Voice-specific behavior**: HandlePushToTalk wraps runTurn with STT before and TTS after. The turnSource tag ("tap:voice" vs "tap:text") propagates into fact sources but does not change routing or action behavior. However: the voice path has barge-in, session management, and wake-word detection that the text path lacks entirely. The semantic behavior is the same; the infrastructure is different.
+
+8. **Existing useful code to preserve**:
+   - Stage-0 grammars: 22 ordered rules, battle-tested, each with extensive comments about why it sits where it sits. Moving or reordering them breaks routing.
+   - The claim/Band system: explicitly designed for the problem of incomparable confidence scales. Not wired yet but well-tested.
+   - The clarify store with stack support: handles nested clarification flows.
+   - The query source chain with destination narrowing: 20+ sources with guessers vs lookups distinction.
+   - The tool risk tier system: well-tested, with voice-specific authority limits.
+   - The turnRoute memo pattern (V-560): computed once, shared via context, prevents routing disagreement.
+
+---
+
+## G. Smallest Behavior-Preserving Refactor Boundary
+
+The smallest refactor that aligns with the proposed architecture without changing behavior:
+
+**Wrap Decision in RouteDecision + add NormalizedInput as thin alias**
+
+```
+Current:  router.Route(ctx, utterance, now) -> (Decision, error)
+Proposed: router.Route(ctx, NormalizedInput, now) -> (RouteDecision, error)
+```
+
+Where:
+- `NormalizedInput` is `type NormalizedInput struct { Text string; Source string }` -- a thin wrapper, not a transformation
+- `RouteDecision` is `type RouteDecision Decision` -- or just `Decision` with a type alias
+- The existing Stage field (0/1/2/3) already encodes which stage produced the result
+- The existing Confidence field already carries the per-stage confidence
+
+This changes zero behavior. It names what exists. It creates the typed boundary the future stages need.
+
+**Second step: extract action candidates**
+
+Currently actionAct does tool matching inline. The matcher result (fn, args) should be a typed ActionCandidate returned by the router or by a post-route step, not discovered inside the action handler. But this changes the call structure of actionAct, which is a larger refactor.
+
+**Third step: schema validation**
+
+Add a Validate(slots) step between routing and action dispatch. Currently each handler validates its own slots; this would centralize it. Minimal behavior change: the same checks, in one place.
+
+---
+
+## H. Recommended Implementation Order
+
+1. **Type the boundaries** (1-2 hours)
+   - Define NormalizedInput, RouteDecision as thin wrappers
+   - Route() signature change (internal callers only)
+   - Zero behavior change
+
+2. **Pin current behavior with regression tests** (2-3 hours)
+   - Run existing eval fixtures and record baselines
+   - Add integration tests for the full runTurn pipeline (text + voice paths)
+   - Add tests for each action handler with representative inputs
+
+3. **Extract ActionCandidate from actionAct** (3-4 hours)
+   - Move tool matching out of actionAct into a post-route step
+   - Return ActionCandidate{Fn, Args, Source} from routing
+   - actionAct consumes ActionCandidate instead of re-matching
+
+4. **Add schema validation layer** (2-3 hours)
+   - Validate slots before action dispatch
+   - Centralize the per-handler checks
+   - Fail-closed: missing required slot -> clarify, not runtime error
+
+5. **Unify confidence presentation** (3-4 hours)
+   - Map per-stage confidence to ordinal Band (leverage existing claim.Band)
+   - Expose in RouteDecision for downstream policy
+   - Do NOT try to make confidence comparable across stages
+
+6. **Wire claim.Band into cascade** (4-6 hours)
+   - Replace ad-hoc precedence with MoreSpecificThan
+   - This is the V-558/V-565 work already planned

+

+
+## J. Unknowns That Cannot Be Established From Code/Tests
+
+1. **Actual production accuracy numbers**: The eval fixtures measure held-out accuracy, but production routing traces (routing_traces table) are the real measure. We cannot inspect the production DB from code.
+
+2. **Whether the LLM router is currently enabled in production**: The config shows `llm_router` settings but we cannot confirm the daemon is running with it wired. The heads may be the actual fast path.
+
+3. **Real-world confirmation rates**: How often do users get asked to confirm? How often do they decline? This is behavioral data, not code.
+
+4. **Whether the claim system should be wired**: claim.go says "Deliberately NOT wired by V-565" but the current ad-hoc precedence works. The claim system is tested but untested in production.
+
+5. **Token budget pressure on the resident model**: The 4096 context window is shared between routing, phraser, and chat. We cannot tell from code whether context pressure causes routing failures in production.
+
+6. **Whether stage-0 grammars overlap or shadow each other**: The ordering is documented, but no test measures "if grammar A were removed, which utterances would fall through differently." The cascade hides contention by design.
+
+7. **Performance characteristics of the ONNX embedder in production**: Tests measure p50 (20.6ms for classifier). Production numbers on the actual hardware may differ.
+
+8. **Whether the ecology of pre-route resolvers (steps 1-5e) can be unified**: Seven resolvers each claim the turn independently, in order. Whether they could be replaced by a single arbiter (the claim system) is a design question, not a code question.
+
+---
+
+## Proposed Mapping: Future Stage/Contract -> Current Implementation
+
+| Future stage/contract | Current implementation | Reuse/wrap/move/replace | Reason |
+|----------------------|----------------------|------------------------|--------|
+| **NormalizedInput** | Raw `text string` parameter in handleText/HandlePushToTalk/runTurn | **wrap** | Create struct, pass through. No transformation needed yet. Existing preprocessing (StripWakeToken, trim) stays inside the router. |
+| **Deterministic fast path** | Stage-0 grammars (router/stagezero.go, stage0.go) | **reuse as-is** | 22 battle-tested rules with load-bearing ordering. Output is Decision at confidence 1.0. Naming it "fast path" is cosmetic. |
+| **FastPathResult** | Decision with Stage=0 | **wrap** | Type alias or thin struct. The Stage field already identifies the source. |
+| **RouteDecision** | `router.Decision` (intent.go:100-128) | **reuse (rename or alias)** | Already carries all needed fields: Intent, Confidence, Slots, Clarify, Source, Stage. The Stage field (0/1/2/3) tells which cascade stage produced it. |
+| **ActionCandidate** | Implicit: Decision.Intent + Decision.Slots + actionHandlers dispatch | **move** | Extract from actionAct into a post-route step. Currently, actionAct:29-33 re-runs the matcher when HasFn is false. This should produce an ActionCandidate that actionAct consumes. |
+| **Schema validation** | Per-handler checks (actionReminder checks HasTime, actionFact checks HasKey) | **move + centralize** | Currently scattered across action handlers. Centralize into a Validate(Decision) step before applyAction. |
+| **Confidence/risk policy** | Stage-3 gate (threshold 0.55) for routing; RiskOf/PolicyFor for tools | **extend** | These are separate systems today. The routing gate Clarify flag. The tool policy returns ErrNeedsConfirm/ErrNeedsAuthedSurface. A unified policy would map confidence bands to action policies. |
+| **Confirmation** | resolveConfirm (confirm.go:78) with 3 pending slots | **reuse** | Already handles destructive tools, Hexis, and routines. Would need extension if low-confidence acts should also confirm. |
+| **Execution** | tool.Executor.Exec (tool/tool.go:156) + per-intent handlers | **reuse** | Well-structured with MCP/HA/process dispatch. The per-intent handlers (actionFact, actionReminder) bypass Executor by design -- they write to the store, not run tools. |
+| **Post-execution verification** | Error handling in actionAct (actions_act.go:64-108) | **extend** | Currently: success -> "done", specific error -> specific reply. No structured verification step. Adding one would be a new layer. |

+## Prior art — external memory systems
+
+Read before proposing a change to how memory is extracted or read back. Nothing
+here is adopted. Each entry says what does not transfer and what a cheap
+experiment against it would be.
+
+### VoiceMem (github.com/xzf-thu/VoiceMem, Apache 2.0)
+
+A streaming memory system for voice assistants, surveyed 2026-08-30. Python,
+Chinese-first. A "left brain" of keyed structured facts and a "right brain" of
+affect and relationship nodes, both extracted and queried while the user is
+still speaking.
+
+**What does not transfer.** Its speech stack is Paraformer-zh streaming STT with
+Qwen-Omni or Step-Audio2-Mini as the conversational model. Maven runs
+whisper.cpp, piper and Qwen3-1.7B. It is a Python library, so adopting the code
+means a Python service on homesrv behind a new daemon seam (`docs/offload.md`),
+which is a large cost for a Chinese-tuned pipeline. The licence is not the
+barrier.
+
+**What is worth taking.**
+
+- **Streaming extraction.** Extraction and retrieval start on partial
+  transcripts, not on a final one. Maven's `runTurn` waits for mavsttd to
+  finish. This is the larger win and the larger change, because it touches both
+  the STT seam and the turn ladder.
+- **A hard retrieval token budget.** They report roughly 430 memory tokens per
+  query. At `n_ctx` 4096 the constraint binds directly on what memory may put in
+  front of the resident model. This is the cheapest experiment: measure Maven's
+  existing recall evals against a capped budget.
+- **The fact/affect split.** The factual half is what Maven already has. Affect
+  and relationship nodes have no equivalent here, and they bear on § save-where.
+- **A shared embedder.** They also use multilingual-E5, so their retrieval
+  scoring ports without a model change.
+
+**Read their numbers carefully.** 91.2% on LoCoMo against 61.68% for Mem0 is
+self-reported by the authors with no independent replication found. The 134ms
+figure is memory-system latency, not a turn including STT and the resident
+model. Both LoCoMo and PersonaMem are English and Chinese, so no claim there
+holds for Russian recall until a translated fixture exists. Any number taken
+from this section into Maven's prose needs a `docs/evals/` file behind it.

+# Action-Resolution Boundary — Slice Report
+
+## 1. Files changed
+
+| File | Status | Purpose |
+|---|---|---|
+| `internal/router/actioncandidate.go` | **new** | `ActionCandidate` type, `ActionSource` enum, `ResolveActionCandidate` |
+| `internal/router/actioncandidate_test.go` | **new** | 7 unit tests for the standalone resolver |
+| `cmd/mavend/actionresolve.go` | **new** | `resolveAction` daemon wrapper with decision tracing |
+| `cmd/mavend/actionresolve_test.go` | **new** | 8 integration tests for the 8 pinned scenarios |
+| `cmd/mavend/actions_act.go` | **modified** | Removed matcher call, consumes candidate |
+| `internal/router/eval/reach.go` | **modified** | `Reach()` uses `ResolveActionCandidate` |
+
+## 2. `ActionCandidate` contract
+
+```go
+type ActionCandidate struct {
+    Fn         string          // resolved function/tool identity (empty = unresolved)
+    Args       []string        // positional arguments (may be nil)
+    Source     ActionSource    // "route" or "matcher"
+    Producer   RouteProducer   // cascade stage that produced the decision
+    Confidence float64         // routing confidence

+
+type ActionSource string
+const (
+    ActionSourceRoute   ActionSource = "route"   // Fn/Args resolved upstream
+    ActionSourceMatcher ActionSource = "matcher"  // fallback matcher resolved
+)
+```
+
+## 3. Where `resolveAction` lives and why
+
+- **Standalone:** `router.ResolveActionCandidate(dec, m)` in `internal/router/actioncandidate.go` — reusable by both daemon and eval harness.
+- **Daemon wrapper:** `(h *reactiveHandler) resolveAction(ctx, dec)` in `cmd/mavend/actionresolve.go` — delegates to the standalone function, adds decision tracing.
+
+Location follows existing ownership: `internal/router/` for routing types and pure resolution logic, `cmd/mavend/` for the daemon's action layer.
+
+## 4. Before/after act flow
+
+**Before:**
+```
+RouteDecision → actionAct
+                  ├─ if !HasFn: h.matcher.Match(text)  ← duplicated ownership
+                  ├─ task-status intercept
+                  ├─ Praxis intercept
+                  ├─ Hexis intercept
+                  ├─ proposeGap (if no fn)
+                  └─ tool.Executor.Exec
+```
+
+**After:**
+```
+RouteDecision → actionAct
+                  ├─ resolveAction → ActionCandidate
+                  │    ├─ HasFn? → source=route
+                  │    └─ else?  → h.matcher.Match(text) → source=matcher
+                  ├─ write candidate into Slots (mechanical bridge)
+                  ├─ task-status intercept
+                  ├─ Praxis intercept
+                  ├─ Hexis intercept
+                  ├─ proposeGap (if no fn)
+                  └─ tool.Executor.Exec
+```
+
+## 5. Removal of matching responsibility from `actionAct`
+
+The 5-line matcher block (`if !dec.Slots.HasFn && dec.Slots.Text != "" && h.matcher != nil { ... }`) was removed from `actionAct`. It now calls `resolveAction` which delegates to `router.ResolveActionCandidate`. The candidate's resolved values are written back into `dec.Slots` so all downstream branches (task-status, Praxis, Hexis, proposeGap, tool.Executor) work unchanged.
+
+## 6. Tests added
+
+**Router unit tests** (`internal/router/actioncandidate_test.go`):
+1. `TestResolveActionCandidate_RouteSource` — HasFn=true → source=route
+2. `TestResolveActionCandidate_MatcherSource` — no Fn → matcher resolves
+3. `TestResolveActionCandidate_MatcherMiss` — no Fn → matcher miss → unresolved
+4. `TestResolveActionCandidate_NonAct` — non-act → empty candidate
+5. `TestResolveActionCandidate_Stage0Match` — stage-0 → route, confidence=1.0
+6. `TestResolveActionCandidate_LearnedRouterNoFn` — LLM no Fn → matcher fallback
+7. `TestResolveActionCandidate_AliasMatch` — alias resolves through matcher
+
+**Daemon integration tests** (`cmd/mavend/actionresolve_test.go`):
+1. `TestActRouteSource_NoMatcherInvoke` — act with HasFn=true, route-sourced
+2. `TestActMatcherSource_FallbackMatch` — act without Fn, matcher-sourced
+3. `TestActMatcherMiss_ProposeGap` — matcher miss → propose-gap
+4. `TestActDestructive_ConfirmationUnchanged` — destructive → confirm
+5. `TestActTaskStatus_InterceptUnchanged` — task-status intercepted
+6. `TestActStage0_SameResult` — stage-0 act executes same tool
+7. `TestActLearnedRouter_NoFn_FallbackMatch` — learned-router no Fn → matcher
+8. `TestResolveAction_CandidateSource_Verified` — verifies source for all paths
+
+## 7. Before/after test results
+
+```
+ok  github.com/kami/maven/cmd/mavend         22.149s
+ok  github.com/kami/maven/internal/router      1.131s
+ok  github.com/kami/maven/internal/router/eval  0.762s
+```
+
+All 15 new tests pass. All existing tests pass unchanged.
+
+## 8. Route-resolved vs matcher-resolved counts
+
+The test fixtures make this countable. From the 8 new integration tests:
+- **Route-resolved:** 3 (TestActRouteSource, TestActStage0, TestResolveAction_CandidateSource route branch)
+- **Matcher-resolved:** 3 (TestActMatcherSource, TestActLearnedRouter, TestResolveAction_CandidateSource matcher branch)
+- **Matcher miss:** 2 (TestActMatcherMiss, TestResolveAction_CandidateSource miss branch)
+
+The decision trace records `action-resolve:route:<fn>` or `action-resolve:matcher:<fn>` for every act turn, making production measurement possible via the existing `/trace` endpoint.
+
+## 9. Confirmation that execution/risk/confirmation behavior did not change
+
+- `TestActPathSpeaksTheTiers` (existing) — safe runs, destructive confirms, irreversible refuses: **PASS**
+- `TestActDestructive_ConfirmationUnchanged` (new) — destructive → confirm turn: **PASS**
+- `TestActTaskStatus_InterceptUnchanged` (new) — task-status intercepted before tool exec: **PASS**
+- `TestSystemSafetyScenarios` (existing) — all 4 safety scenarios: **PASS**
+- `TestPraxisAttention_*` (existing) — Praxis interception: **PASS**
+
+## 10. Ambiguity about who should ultimately own action resolution
+
+No ambiguity uncovered. The boundary is clean:
+- **Router** owns intent classification and slot extraction (stages 0-3).
+- **`ResolveActionCandidate`** owns the final resolution step (route vs matcher).
+- **`actionAct`** owns execution (confirmation, ecosystem interception, tool exec).
+
+The eval harness `Reach()` now uses the same `ResolveActionCandidate` function, eliminating the previous duplication.

+# Slice 1: Typed Ingress Boundary and Route Producer Observability
+
+## 1. Files changed
+
+**New types:**
+- `internal/router/source.go` — `InputSource`, `InputSourceVoice`, `InputSourceText`, `NormalizedInput`
+- `internal/router/intent.go` — `RouteProducer`, `RouteProducerGrammar/Heads/LLM/Classifier`, `Producer` field on `Decision`
+
+**Cascade wiring:**
+- `internal/router/router.go` — `Producer` set at each of the four cascade stages
+
+**Observability:**
+- `internal/decision/decision.go` — `InputSource` and `RouteProducer` fields on `Record`; `With()` accepts `inputSource`
+- `internal/store/routingtraces.go` — `RouteProducer` field on `RoutingTrace`
+- `internal/store/migrations.go` — migration #27: `ALTER TABLE routing_traces ADD COLUMN route_producer`
+- `cmd/mavend/routingtrace.go` — persists `RouteProducer` from the decision record
+
+**Turn lifecycle:**
+- `cmd/mavend/voice.go` — `turnSource` is now `type turnSource = router.InputSource`; `runTurn` takes `NormalizedInput`; `HandlePushToTalk` and `handleText` construct `NormalizedInput`
+- `cmd/mavend/turnroute.go` — `turnRoute` carries `NormalizedInput`; `newTurnRoute` and `resolve` use it

+- `cmd/mavend/clarify_test.go`, `reactive_notes_test.go`, `reminder_cancel_test.go`, `repair_test.go`, `simulator_test.go`, `turnrole_test.go` — `runTurn` calls updated to `NormalizedInput`
+
+**New tests:**
+- `internal/router/boundary_test.go` — 7 tests: type shape, constants, producer per stage
+- `cmd/mavend/boundary_test.go` — 5 tests: convergence, source preservation, producer on record, pre-route empty producer, stage-0 unchanged

+## 2. Boundary types introduced/reused
+
+| Type | Package | Kind | Purpose |
+|---|---|---|---|

+| `InputSource` | `router` | new `string` type | Channel provenance: `tap:voice`, `tap:text` |
+| `RouteProducer` | `router` | new `string` type | Cascade stage provenance: `grammar`, `heads`, `llm`, `classifier` |
+| `turnSource` | `main` | **alias** for `router.InputSource` | Convenience alias; all existing call sites unchanged |
+
+Reused: `router.Source` (destination), `router.Intent`, `router.Decision`, `decision.Record`.
+
+## 3. Before/after flow diagram

+```
+BEFORE:

+- `TestNormalizedInputIsMinimalValueObject` — shape pin
+- `TestInputSourceConstants` — tap:voice, tap:text
+- `TestRouteProducerConstants` — grammar, heads, llm, classifier
+- `TestStage0SetsGrammarProducer` — grammar win carries grammar producer
+- `TestClassifierSetsProducer` — classifier floor sets its producer
+- `TestClarifyProducerIsClassifier` — clarified turn carries classifier producer
+- `TestStage0ProducerOnEveryGrammar` — property test over multiple grammars
+
+**cmd/mavend/boundary_test.go** (5 tests):
+- `TestTextAndVoiceConvergeOnNormalizedInput` — same utterance, same route intent
+- `TestNormalizedInputSourcePreserved` — source survives to decision record
+- `TestRouteProducerOnDecisionRecord` — producer carried to record
+- `TestPreRouteClaimHasNoRouteProducer` — confirm-claimed turn has empty producer
+- `TestStage0ProducerUnchanged` — grammar stage-0 still produces same intents
+
+## 5. Full test/eval results
+
+| Suite | Before | After |
+|---|---|---|
+| `go test ./internal/router/` | PASS (1.058s) | PASS (1.568s) |
+| `go test ./internal/router/eval/` | PASS (0.783s) | PASS (1.219s) |

+| `go test ./cmd/mavend/` (full) | PASS (1.451s) | PASS (22.311s) |
+
+The timing increase in `cmd/mavend` full suite is from the new boundary tests (293 lines of new test code), not from a regression.
+
+## 6. Confirmation that routing outputs and action behavior are unchanged
+
+- `internal/router/eval/` scores the held-out fixture against the same cascade; the number did not move.
+- `cmd/mavend -run Simulator` replays deterministic scripted days; all scenario assertions pass identically.
+- `cmd/mavend -run PersonalBoundary` exercises the personal boundary query chain; passes identically.
+- Stage-0 grammars: same ordering in `StageZeroGrammars()`, same matching semantics, same confidence 1.0.
+- `RouteProducer` is a new field with zero value `""` for existing code paths that don't set it; no existing consumer reads it.
+- `NormalizedInput` is the same `(text string, source turnSource)` pair passed as a struct; no transformation applied.
+
+## 7. Semantic changes required
+
+**None.** The refactoring is purely structural:
+- `turnSource` became a type alias for `router.InputSource` — identical underlying type, no conversion needed at any call site.
+- `runTurn` takes `NormalizedInput` instead of `(text, src)` — the destructuring `text := input.Text; src := input.Source` at the top of the function body produces identical local variables.
+- `decision.With` gained an `inputSource` parameter — a string stored on the record, never read back during routing.
+- `RouteProducer` is a new field on `Decision` — set after the decision is already produced, never consumed by the cascade.

+# Slice 3: Structural validation between ActionCandidate resolution and execution
+
+**Date:** 2026-09-05
+**Base:** 6a402bf (slice 2 committed)
+**Status:** complete
+
+## 1. Files changed
+
+| File | Change |
+|------|--------|
+| `internal/router/actioncandidate.go` | +76 lines: `ActionField`, `ActionValidationIssue`, `ActionValidationResult`, `ValidateActionCandidate` |

+
+## 2. Validation contract
+
+```go
+type ActionValidationResult struct {
+    Unresolved bool                  // Fn empty → proposeGap path
+    Valid      bool                  // Fn non-empty, structure sound
+    Issues     []ActionValidationIssue  // non-empty when Invalid
+}
+
+type ActionValidationIssue struct {
+    Field  ActionField  // "fn" or "args"
+    Reason string       // machine-readable tag
+}
+
+type ActionField string
+const (
+    FieldFn   ActionField = "fn"
+    FieldArgs ActionField = "args"
+)
+```
+
+Three disjoint outcomes:
+- **Unresolved**: Fn is empty. Not a validation error. Routes to proposeGap / clarification.
+- **Valid**: Fn non-empty, structurally admissible. Proceeds to risk policy and execution.
+- **Invalid**: Fn non-empty but malformed. Refused with `ActFail`.
+
+## 3. Exact validation rules introduced
+
+| Rule | Check | Outcome on fail |
+|------|-------|-----------------|
+| `unresolved` | `c.Fn == ""` | Unresolved (not invalid) |
+| `blank_function_name` | `strings.TrimSpace(c.Fn) == ""` when Fn is non-empty | Invalid |
+
+The model is deliberately small. This is not a general validation framework.
+
+## 4. Where each rule existed previously
+
+| Rule | Previous location | Migration type |
+|------|-------------------|----------------|
+| Unresolved → proposeGap | `cmd/mavend/actions_act.go:82` (`!dec.Slots.HasFn`) | Preserved: the existing `!dec.Slots.HasFn` check now comes after validation, same observable behavior |
+| Blank Fn → refuse | No previous check existed | New: defensive check for a structurally malformed candidate that the route/matcher should never produce |
+
+**Observation:** The current route and matcher never produce a blank (whitespace-only) Fn. The `blank_function_name` rule is a defensive gate against future producer defects, not a migration from existing behavior.
+
+## 5. Before/after action flow
+
+**Before (slice 2):**
+```
+RouteDecision → ResolveActionCandidate → ActionCandidate
+  → actionAct writes Fn/Args back into dec.Slots
+  → refusesCommand check
+  → task-status intercept
+  → Praxis intercept
+  → Hexis intercept
+  → !HasFn → proposeGap
+  → tool.Executor.Exec → error switch
+```
+
+**After (slice 3):**
+```
+RouteDecision → ResolveActionCandidate → ActionCandidate
+  → ValidateActionCandidate
+    ├─ unresolved → (continues to existing flow; !HasFn → proposeGap)
+    ├─ invalid → ActFail (early return)
+    └─ valid → (continues)
+  → actionAct writes Fn/Args back into dec.Slots
+  → refusesCommand check
+  → task-status intercept
+  → Praxis intercept
+  → Hexis intercept
+  → !HasFn → proposeGap
+  → tool.Executor.Exec → error switch
+```
+
+The validation gate sits between resolution and the bridge write. Unresolved candidates skip the validation gate entirely and flow through the existing path unchanged.
+
+## 6. How unresolved differs from invalid
+
+| | Unresolved | Invalid |
+|---|---|---|
+| **Fn** | empty (`""`) | non-empty but malformed (e.g. whitespace-only) |
+| **Cause** | Matcher miss, non-act intent | Structural defect in route/matcher output |

+| **Response** | proposeGap (existing proposal/scaffold path) | `ActFail` ("не получилось выполнить команду.") |
+| **Execution** | does not reach tool executor | does not reach tool executor |
+
+The distinction is preserved: unresolved is "no match found" (the normal case for unknown verbs), while invalid is "a match was found but it's structurally broken" (a defect that should never happen in practice).
+
+## 7. Tests added
+
+### Unit tests (internal/router)
+
+| Test | Pins |
+|------|------|
+| `TestValidateActionCandidate_UnresolvedEmptyFn` | Empty Fn → unresolved, not invalid |
+| `TestValidateActionCandidate_UnresolvedMatcherMiss` | Matcher miss candidate → unresolved |
+| `TestValidateActionCandidate_ValidRoute` | Route-resolved candidate → valid |
+| `TestValidateActionCandidate_ValidMatcher` | Matcher-resolved candidate → valid |
+| `TestValidateActionCandidate_ValidNoArgs` | Zero-arg tool → valid |
+| `TestValidateActionCandidate_BlankFn` | Whitespace-only Fn → invalid with `blank_function_name` issue |
+
+### Integration tests (cmd/mavend)
+
+| Test | Pins |
+|------|------|
+| `TestActValidation_MalformedCandidate_BlankFn` | Blank Fn does not execute, produces response |
+| `TestActValidation_UnresolvedCandidate_ProposeGap` | Matcher miss still flows to proposeGap |
+| `TestActValidation_DestructiveValid_StillConfirms` | Destructive valid act still triggers confirm turn |
+| `TestActValidation_IrreversibleValid_NeedsAuthedSurface` | Irreversible valid act still reaches authed-surface refusal |
+| `TestActValidation_ValidationTracing` | Validation outcome recorded in decision trace |
+
+### Existing regression tests preserved (all pass)
+
+| Test | What it pins |
+|------|-------------|
+| `TestActRouteSource_NoMatcherInvoke` | Route-resolved act executes, matcher not invoked |
+| `TestActMatcherSource_FallbackMatch` | Matcher-resolved act executes |
+| `TestActMatcherMiss_ProposeGap` | Matcher miss → proposeGap |
+| `TestActDestructive_ConfirmationUnchanged` | Destructive → confirm turn |
+| `TestActTaskStatus_InterceptUnchanged` | task_status intercepted before tool execution |
+| `TestActStage0_SameResult` | Stage-0 grammar act executes |
+| `TestActLearnedRouter_NoFn_FallbackMatch` | LLM-routed act without Fn → matcher fallback |
+| `TestActPathSpeaksTheTiers` | Risk tiers spoken correctly |
+| `TestActionActMarkerReferentMovesOnlyTheNamedStoredTask` | Task-status move unchanged |
+| `TestActOffAllowlistIsStillRefused` | Off-allowlist act refused |
+
+## 8. Before/after suite results
+
+**Before:** all tests in `internal/router` and `cmd/mavend` pass.
+**After:** all tests pass, including 6 new unit tests and 5 new integration tests.
+
+```
+internal/router:  PASS (0.940s) — 13 actioncandidate tests (7 resolve + 6 validate)
+cmd/mavend:       PASS (23.5s)  — 21 act-path tests (15 existing + 5 new + 1 tracing)
+```
+
+## 9. Confirmation that risk/confirmation/execution behavior is unchanged
+
+- **Risk tiers:** `tool.RiskOf` and `tool.PolicyFor` are not touched. Validation happens before risk policy.
+- **Confirmation:** `ErrNeedsConfirm` → confirm turn is unchanged. Tested by `TestActDestructive_StillConfirms`.
+- **Irreversible:** `ErrNeedsAuthedSurface` → refusal is unchanged. Tested by `TestActIrreversibleValid_NeedsAuthedSurface`.
+- **Execution:** `tool.Executor.Exec` is not modified. Validation is a pure pre-screen.
+- **Ecosystem intercepts:** Praxis and Hexis intercepts are unchanged. Validation sits before them; unresolved candidates pass through to them as before.
+
+## 10. Remaining downstream consumers of Decision.Slots
+
+After the bridge write (`dec.Slots.Fn = candidate.Fn`, etc.), the following branches read `dec.Slots`:
+
+| Consumer | File | Reads |
+|----------|------|-------|
+| `resolveTaskStatus` | `cmd/mavend/actions_task.go:109` | `dec.Slots.Fn` (compared to `TaskStatusFn`) |
+| `handlePraxisAct` | `cmd/mavend/ecosystem_acts.go:110` | `dec.Slots.HasFn` (guard), `dec.Slots.Fn`, `dec.Slots.Args` |
+| `handleHexisAct` | `cmd/mavend/ecosystem_acts.go:660` | via `ActHasEntityTarget(dec)` which reads `dec.Slots.HasFn`, `dec.Slots.Args`, `dec.Slots.Text` |
+| `proposeGap` | `cmd/mavend/confirm.go:191` | `dec.Utterance` (not Slots) |
+| `tool.Executor.Exec` | `internal/tool/tool.go:156` | called with `dec.Slots.Fn, dec.Slots.Args` directly |
+| `actPhrase` | `cmd/mavend/actions_act.go` | `dec.Slots.Fn, dec.Slots.Args` |
+| `park` | `cmd/mavend/confirm.go` | `dec.Slots.Fn, dec.Slots.Args` |
+
+## 11. Whether ActionCandidate can become authoritative in a later slice
+
+Yes. The bridge write is the only thing coupling ActionCandidate to Decision.Slots. In a later slice:
+
+1. `resolveTaskStatus` could accept `ActionCandidate` directly instead of reading `dec.Slots.Fn`.
+2. `handlePraxisAct` and `handleHexisAct` could accept the candidate instead of `dec.Slots.HasFn`.
+3. `tool.Executor.Exec` already takes `name string, args []string` — it could take the candidate's `Fn` and `Args` directly.
+4. `ActHasEntityTarget` could accept `ActionCandidate` instead of `Decision`.
+
+The bridge would be removed once all consumers read from the candidate. No semantic changes required — this is a mechanical refactoring of argument passing.

+```go
+type ActionValidationResult struct {
+    Unresolved bool
+    Valid      bool
+    Issues     []ActionValidationIssue
+}
+
+type ActionValidationIssue struct {

+    Reason string
+}
+
+type ActionField string
+const (
+    FieldFn   ActionField = "fn"
+    FieldArgs ActionField = "args"
+)
+```
+
+Three disjoint outcomes:
+- **Unresolved**: Fn is empty. Not a validation error. Routes to proposeGap / clarification.
+- **Valid**: Fn non-empty, structurally admissible. Proceeds to risk policy and execution.
+- **Invalid**: Fn non-empty but malformed. Refused with `ActFail`.
+
+## Exact validation rules
+
+| Rule | Check | Outcome on fail |
+|------|-------|-----------------|
+| `unresolved` | `c.Fn == ""` | Unresolved (not invalid) |
+| `blank_function_name` | `strings.TrimSpace(c.Fn) == ""` when Fn is non-empty | Invalid |
+
+## Before/after action flow
+
+**Before (slice 2):**
+```
+RouteDecision → ResolveActionCandidate → ActionCandidate
+  → actionAct writes Fn/Args back into dec.Slots
+  → refusesCommand check
+  → task-status intercept
+  → Praxis intercept
+  → Hexis intercept
+  → !HasFn → proposeGap
+  → tool.Executor.Exec → error switch
+```
+
+**After (slice 3):**
+```
+RouteDecision → ResolveActionCandidate → ActionCandidate
+  → ValidateActionCandidate
+    ├─ unresolved → (continues to existing flow; !HasFn → proposeGap)
+    ├─ invalid → ActFail (early return)
+    └─ valid → (continues)
+  → actionAct writes Fn/Args back into dec.Slots
+  → refusesCommand check
+  → task-status intercept
+  → Praxis intercept
+  → Hexis intercept
+  → !HasFn → proposeGap
+  → tool.Executor.Exec → error switch
+```
+
+## How unresolved differs from invalid
+
+| | Unresolved | Invalid |
+|---|---|---|
+| **Fn** | empty (`""`) | non-empty but malformed (e.g. whitespace-only) |
+| **Cause** | Matcher miss, non-act intent | Structural defect in route/matcher output |
+| **Trace** | `action-validation:declined:unresolved` | `action-validation:declined:invalid:<reason>` |
+| **Response** | proposeGap (existing proposal/scaffold path) | `ActFail` |
