### Stop shipping a forked aep-record schema; consume canonical aep/v0.3 from @wasmagent/protocol
## Context
`packages/aep/schemas/aep-record.schema.json` is generated from the Zod `AEPRecordSchema` (`packages/aep/scripts/export-json-schema.ts`) and has **drifted ahead of** the canonical `@wasmagent/protocol` `aep-record` (`aep/v0.2`): it adds `user_id`, `subject_id`, `run_side_effect_class_max`, reaches `aep/v0.3`, and makes `signature` required.
Issue #147 ("Strip local AEP/compliance schemas") was closed once `@wasmagent/protocol` shipped, and the **compliance family + rollout-wire were

### [shared-state 6/9] Affordance projection (reduce illegal tool calls)
> Part of #133 (shared-state epic)
**Depends on:** #134
**Blocks:** none
**Part of:** the shared-state epic (link added on creation)
**Note:** independent of STORE — can be developed against a `StateModel` alone, so it may land early in parallel.
## Motivation
Tell the agent not just *what the state is* but *what it can legally do next*. E.g. *"detailMode is 'view', so `OPEN_FORM` is available but `SET_FORM_FIELDS` is not (no form is open)."* This brings a statechart-style guard (XState-inspi

### aep/types: no schema signal for 'system permission layer gated this action' (paired with open-agent-audit false-positive)
# No AEP event / adapter mapping for "system permission layer already gated this action"
**Repo:** `packages/aep` (paired with an open-agent-audit issue on the adapter side)
## Problem
When the platform's permission layer denies (or automatically approves) a high-risk tool call, the wasmagent AEP emitter records `action.capability_decision.decision = 'deny'` (or 'allow'), and that's all. Downstream, open-agent-audit's canonical schema does have a `human_approval` event type, but no adapter ma

### Document key architecture decisions to reduce bus factor: AEP v0.4, trust-cli, Milestone 5 trace archival
## Problem
Core architectural decisions are currently implicit in code and commit messages. With 1-2 primary authors, loss of context is a real risk. Three areas need documented design rationale:
## Tasks
### 1. AEP v0.4 design doc (`docs/aep-v0.4-design.md`)
- Why DSSE/in-toto envelope was chosen over HMAC-only
- `recording_mode` semantics and privacy tradeoffs
- `taint_labels` / `output_taint_labels` propagation rules
- Relationship to in-toto `agent-decision` predicate

@wasmagent/aep: provide registerStatefulVerbs() to avoid parallel MUTATING set + isStateChangingTool
Problem
Backends that use @wasmagent/aep for audit logging need to know which tools are state-changing at two different call sites:
isStateChangingTool(name)— used by AEP to classify evidence records- A hand-maintained
MUTATINGSet — used by the chat service to triggerlogEvent()and setstateChanging: trueonChatToolLog
These two must be kept in sync manually. When a new tool is added (e.g. approve_vendor), it's easy to update one and forget the other. The bug is sile

@wasmagent/core: promote injectHistoryIntoAssembler as a first-class exported API
Problem
Every Express/Node.js backend that uses ToolCallingAgent in a stateless HTTP handler needs to replay prior conversation turns into the assembler before each request. The logic is non-trivial — it must handle three message shapes:
- Pure text turns (
role: assistant, content: string) - Single tool use (
tool_use+tool_resultblock pair) - Parallel tool calls (multiple
tool_useblocks + multipletool_resultblocks)
This mapping from Anthropic wire format → wasmagent ass

@wasmagent/compliance: add verifyObject() API for in-memory validation without a WorkspaceReader
Problem
ComplianceVerifier requires a WorkspaceReader (file-system adapter) even when the data to validate is already in memory. For backends that verify domain objects (e.g. a PR draft struct) rather than files, this forces callers to construct a fake filesystem shim:
// Current — must fake a WorkspaceReader
const reader = {
readFile: async (path: string) => {
if (path === 'draft.json') return JSON.stringify(draft)
throw new Error('not found')
},

### useAgentRun hardcodes ev.event field name — incompatible with backends that use ev.type
## Problem
`useAgentRun` from `@wasmagent/react` hardcodes `ev.event` as the event discriminator throughout the SSE parser:
```ts
if (ev.event === 'tool_call' && ev.channel === 'tool') { ... }
if (ev.event === 'final_answer' && ev.channel === 'text') { ... }
This means the hook's built-in message accumulation only works with the Cloudflare Worker /run endpoint which emits AgentEvent objects. Any other compatible backend that emits { type: 'tool_start', ... } (including the standar
