feat(agent-harness): authorize internal maintenance operations

[iscekic]

No new behavior — These maintenance operations are not active in the product.

---

Summary

executeHarnessMaintenance implements HarnessOperation reads, history imports, and text projection behind fresh primary authority and request-bound capabilities, preventing access through stale grants.
history requires matching durable receipts before acknowledging signed importLegacy deliveries; projection binds the conversation, message key, and returned identifier.
retirement authorizes signed purge requests only against matching agent_harness_retirements fences, allowing deleted accounts without live grants and leaving stored data unchanged.

Files

• apps/web/src/lib/agent-harness/operation-maintenance.ts — Added source (+138/−0 lines). Returns strictly validated, bounded QuickChatAuthoritySchema data for read. Bounds input and history output, validates delivery identifiers and requested counts, and restricts delivery statuses to acknowledged, retry, or rejected. Reports backlog as pending or drained, and rejects mismatched projection keys or result identifiers. Checks HS256 signatures, strict claims, issuer, audience, request digest, dispatch, thread, generation, and a 60-second maximum before reading the primary retirement fence. Rejects future issue times and expired tokens. Maps late QuickChatAuthorityError failures to FORBIDDEN.
• apps/web/src/lib/agent-harness/operation-maintenance.test.ts — Added test (+369/−0 lines). Covers personal and organization authority, revocation, substituted scope and ownership, history progress, projection binding, byte limits, malformed output, sanitized failures, and retirement fences. Exercises the actual sender and acknowledgment callback with fake primary storage and transport. Verifies the fixed route, request headers, signature, body digest, message-based dispatch identity, and timestamp normalization. Keeps history pending until a matching durable receipt, including invalid-receipt and transport-failure cases.

Tests: 1 test file added — operation-maintenance.test.ts (+369/−0 lines).
Generated: 0 files changed.

Visual Changes

Visual Changes: N/A

Verification

Manual verification: not run because no endpoint activates at this level.
The evidence does not establish actual PostgreSQL execution or deployed runtime behavior.

Reviewer Notes

Human steps

None before or after merge. This level adds no new required setting, secret, migration, flag, or deployment order.

Recorded checks

• The handoff reports 59 passing tests and passing scoped lint, format, and whitespace checks.
• This description round did not rerun the product checks.
• Full checks and actual PostgreSQL execution remain with continuous integration (CI).

Scope

• Repository: Kilo-Org/cloud; worktree: /Users/igor/Projects/.worktrees/shared-agent-harness-3bb0.
• Review range: shared-agent-harness-3bb0-s30...shared-agent-harness-3bb0-s31.
• This level does not add named dispatch, provider operations, or endpoint composition.

Notes

Runtime verification remains pending at the stack tip. This level adds authorized maintenance operations without activating an endpoint.

Stacked PRs — merge bottom to top. Each level shows only its own diff.

Runtime verification (E2E, user advocacy, simplify) runs on the tip PR over every level.
Every level keeps its own checks, its own bot review, and its own threads; each one is answered on its own PR.
Each level is its own deliverable: it builds and passes its own checks alone.
A finding on a level is repaired on that level, then carried upward with stack.sh forward.
