Phase 5 (final) of the unified requests/inbox RFC. The four legacy approval MCP tools become thin shims over the unified /requests subsystem (kind=approval). Tool names and parameter signatures are unchanged — fully backward-compatible. New approvals now land in the unified requests table and surface in the unified inbox / Approvals tab.

Shimmed handlers → new endpoints

Handler	New endpoint	Body
`handleCreateApproval(workspace_id, action, reason?)`	`POST /workspaces/{id}/requests`	`{kind:"approval", recipient_type:"user", recipient_id:"", title: action, detail: reason}`
`handleDecideApproval(workspace_id, approval_id, decision)`	`POST /workspaces/{id}/requests/{approval_id}/respond`	`{action: decision==="approved" ? "approved" : "rejected", responder_type:"user", responder_id:"admin"}` (legacy `denied` maps to `rejected`)
`handleListPendingApprovals()`	`GET /requests/pending?kind=approval`	—
`handleGetWorkspaceApprovals(workspace_id)`	`GET /workspaces/{id}/requests` (outgoing)	—

Each tool description gains: (deprecated — routes to the unified requests system; prefer create_request / respond_request).

P1-contract gap noted

The per-workspace reads ListOutgoing (GET /workspaces/:id/requests) and ListInbox (.../requests/inbox) take only a status filter — P1 has NO kind query param on those reads. So get_workspace_approvals cannot filter to approvals server-side; it returns the workspace's outgoing requests (tasks + approvals). The cross-org GET /requests/pending does support ?kind=approval, which list_pending_approvals uses. We deliberately did not invent a kind query param the server would ignore.

Docs

README.md: added a Requests / Inbox highlights row; marked Approvals deprecated-but-supported; annotated the management-mode Audit row.
CLAUDE.md: tool registry's Approvals section rewritten as deprecated shims with a routes-to column.
RFC doc not present in this repo (docs/design/rfc-unified-requests-inbox.md lives in molecule-core), so skipped here.

Tests

src/__tests__/index.test.ts approval tests re-pointed to assert the /requests endpoints + request bodies (fetch-mock, existing style). Tool count unchanged (handlers re-pointed, no tools added/removed) — management.test.ts tool-count assertion still passes.

Build / test

npm run build — clean (tsc)
npx jest — 10 suites passed, 283 passed / 1 skipped

Merges AFTER P1 (molecule-core #2525) and P2 (molecule-mcp-server #56).

Phase 5 (final) of the unified requests/inbox RFC. The four approval MCP
tools keep their original names and parameter signatures (fully
backward-compatible) but their handlers now route to the unified /requests
endpoints with kind=approval instead of the legacy /approvals endpoints, so
new approvals land in the unified requests table and surface in the unified
inbox/Approvals tab.

Shimmed handlers -> new endpoints:
- handleCreateApproval        -> POST /workspaces/:id/requests (kind=approval, recipient_type=user, recipient_id="", title=action, detail=reason)
- handleDecideApproval        -> POST /workspaces/:id/requests/:id/respond (action approved|rejected; legacy denied->rejected; responder_type=user, responder_id=admin)
- handleListPendingApprovals  -> GET  /requests/pending?kind=approval
- handleGetWorkspaceApprovals -> GET  /workspaces/:id/requests (outgoing)

P1-contract note: the per-workspace reads (ListOutgoing/ListInbox) take only
a status filter — P1 has NO kind query param there — so get_workspace_approvals
returns the workspace outgoing requests (tasks + approvals); the cross-org
/requests/pending DOES support ?kind=approval.

Each tool description gains a deprecation note. Docs (README, CLAUDE.md tool
registry) updated to describe the unified requests/inbox tools and mark the
approval tools deprecated-but-supported. Tests in index.test.ts re-pointed to
assert the /requests endpoints; tool count unchanged.

Merges AFTER P1 (molecule-core #2525) and P2 (molecule-mcp-server #56).

qa APPROVE (5-axis, 1st genuine lane — author devops-engineer≠me; CR-A security via cb15acea = 2nd). Correctness: P5 — the 4 approval tools (list_pending_approvals/decide_approval/create_approval/get_workspace_approvals) become BACKWARD-COMPAT DEPRECATED SHIMS routing to the unified /requests subsystem with kind=approval (RFC unified-requests-inbox). Names + parameter signatures preserved; decide_approval→POST /workspaces/:id/requests/:id/respond (legacy decision=denied→action=rejected), create→POST /requests (kind=approval), list→GET /requests/pending?kind=approval. Sound routing. Robustness/Tests: non-vacuous — assert the EXACT endpoint URLs + POST bodies (action/responder_type/responder_id/kind/title/detail) + the legacy denied→rejected mapping. ⚠️ APPROVAL-INTEGRITY (the critical axis): the tools are CLIENT SHIMS — they FORWARD the decision to the server-side /respond endpoint; they do NOT and CANNOT self-enforce approval-integrity (no self-approve/forge/bypass is possible AT the tool layer because the tool has no authority — it just POSTs). The responder_type=user/responder_id=admin are CLIENT-SUPPLIED LABELS in the body; the real authz boundary is server-side (the workspace-server /respond handler must derive identity from the authenticated token, NOT trust the client responder_id). This PR introduces NO NEW integrity risk — it routes to the SAME /respond endpoint the unified respond_request tool already uses (boundary unchanged). NON-BLOCKING server-side note (pre-existing, not introduced here): confirm /respond validates authz from the token vs the client responder fields. Security/Content-sec: clean — 0 eval/exec/child_process, 0 cred-values, deprecation-only client routing. Performance: n/a. Readability: clear deprecation docs (CLAUDE.md/README). Gate green, mergeable. Approving the shim; integrity is server-side-bounded + unchanged.

Security 5-axis — APPROVE (head 5adc303d47). feat(requests): P5 — legacy approval tools become deprecated aliases routing to the unified requests system (+105/-40, approvals.ts + docs + tests). 2nd security lane (CR-B 1st); author devops-engineer != me.

Correctness: the legacy approval tools now route to the unified endpoints — decide → POST /workspaces/:id/requests/:id/respond (was /approvals/:id/decide), list/create → /requests; decision 'approved'→approved, else→rejected, legacy 'denied'→'rejected' (semantics preserved); deprecation notices added steering to create_request/respond_request. ✓
AUTHZ: the approval-decide alias sets responder_type=user, responder_id=admin — the legitimate ADMIN-approver path (server-side AdminAuth-gated, the SAFE side, like #2527's canvas path). Same as mcp#56, the unified-requests endpoints' authz is enforced SERVER-SIDE → same dependency on core#2525's participant-binding (RC 10416); ships as a pair with the server fix. Non-blocking: responder_id='admin' is coarse for audit (doesn't capture which admin) — fine for the legacy alias.
No cred-leak (centralized auth'd client), no injection (typed params → JSON). Tests updated.
Gate GREEN. APPROVE → 2-distinct with CR-B. (Gated, like mcp#56, on #2525's server authz fix.)
