Second phase of the Multi-Agent Workbench rollout (docs/plans/
multi-agent-workbench.md). Builds on Phase 1's identity-aware Actor.
Adds the Agent primitive — a named AI persona that owns Missions,
carries its own policy + memory, and (from Phase 3 on) drives the
Workbench lens. Everything is wired; a single user currently has one
"Mana" default agent until the UI (Phase 5) lets them create more.
Shared types (@mana/shared-ai):
- agents/types.ts: Agent, AgentState, DEFAULT_AGENT_ID/NAME constants
- policy/types.ts: AiPolicy + PolicyDecision (moved from webapp so
Agent.policy can reference it without a runtime dep on the web app)
- missions/types.ts: new optional Mission.agentId field
Webapp data layer:
- data/ai/agents/{types,store,queries,bootstrap}.ts
- Dexie schema v19 adds `agents` table (indexes on state, name,
[state+name]); sync registered under the existing ai app-id
- Encryption registry: agents.systemPrompt + agents.memory encrypted;
name/role/avatar/policy stay plaintext for search + UI rendering
- DuplicateAgentNameError thrown at write time (not a Dexie unique
index — bootstrap races between tabs would otherwise hit
ConstraintError; store now resolves via getOrCreateAgent)
- bootstrap.ts: ensureDefaultAgent + backfillMissionsAgentId. The
backfill runs once per device (localStorage sentinel) so missions
that pre-date the rollout get stamped with the default agent's id.
Called fire-and-forget from startMissionTick() during layout init.
Runner threading (already merged into d5c351d63 via Till's debug-log
commit that picked up my uncommitted edits):
- runner.ts + server-iteration-staging.ts now resolve mission.agentId
to the real Agent and build makeAgentActor with agent.name as
displayName. Missing-agent fallback keeps using LEGACY_AI_PRINCIPAL
so historical writes still attribute cleanly.
Tests: shared-ai 26/26, mana-ai 35/35, svelte-check 0 errors.
Agent store vitest suite is present but blocked by a pre-existing
\$lib alias resolution issue in the webapp vitest config that
predates this phase (proposals/store.test.ts is broken the same way
on HEAD). Will address separately.

Makes the webapp's AI policy and the server's tool allow-list physically
impossible to drift. Adds the missing entries the guard caught on first
run: `complete_tasks_by_title`, `visit_place`, `undo_drink` now have
parameter schemas server-side too.
- `packages/shared-ai/src/policy/proposable-tools.ts`
- `AI_PROPOSABLE_TOOL_NAMES` as `const` array + literal union type
- `AI_PROPOSABLE_TOOL_SET` for set-membership checks
- Webapp `DEFAULT_AI_POLICY` derives its `propose` entries from the
shared list via `Object.fromEntries(...)` — adding a tool there is now
a one-line change in `@mana/shared-ai`
- mana-ai `AI_AVAILABLE_TOOLS`: module-load assertion compares its
hardcoded names against `AI_PROPOSABLE_TOOL_SET` and throws with a
pointed error on drift (extras in one direction, missing in the
other). Service refuses to start on mismatch — better than silent
degradation.
- Bun test (`tools.test.ts`) runs the same contract plus sanity checks
(non-empty description, required params carry docs). Vitest policy
test adds the symmetric check on the webapp side.
All three runtimes now green: webapp 66/66, shared-ai 2/2,
mana-ai 9/9 Bun tests.
