# Task ID: 161

**Title:** Deferred: Per-agent memory and coverage ledger placeholder

**Status:** pending

**Dependencies:** 147, 150

**Priority:** low

**Description:** Placeholder task for agent memory and commit-pinned coverage ledger - blocked on design questions

**Details:**

DEFERRED - DO NOT IMPLEMENT YET

Concepts:
- Global per-agent memory plus per-project knowledge
- Commit-pinned coverage ledger enabling delta-verification
- Non-negotiable: invalidation when covered region changes (or ledger becomes false confidence)
- Trust boundary: ledger is platform-verified machine fact; agent prose notes are opinion, never the gate

Expand this task when prerequisite infrastructure exists.

**Test Strategy:**

N/A - placeholder only
merge: AgentProject membership — the junction is now load-bearing Merges feat/agent-project-membership (task 166/152). An agent can finally join many projects: membership routes, per-membership role and optional brain override, chat resolving context from the membership, and CLI attach-agent / detach-agent / get memberships. The legacy Agent.projectId fallback is kept for this release as the schema comment promises. Conflict resolved in main.ts: that branch added its RBAC case to mapUrlToPermission inline, while this branch had extracted the function to middleware/url-permission.ts so it could be tested. Kept the extraction and ported the case into it — joining a team is `edit:agents:<name>`, not `create:agents`, which is the authority to mint a whole agent. Also fixes something the extraction makes possible. security.test.ts contained a hand-copied reproduction of mapUrlToPermission, because main.ts self-invokes main() and nothing in it was importable. A security test asserting against a copy stops testing the system the moment the real one changes, and this copy had already drifted. It now imports the real function; all 18 assertions still pass, against the code that actually runs. Local: build clean, workspace 2550 passed, lint unchanged at 794 errors.
