shankar0123	0725713e19	Close I-004 (agent hard-delete cascades targets) coverage-gap finding ... Operator decision answered as full soft-delete with optional forced cascade — hard-delete is not reachable from any public surface. Prior to this commit, DELETE /agents/{id} ran a plain `DELETE FROM agents` whose schema-level `ON DELETE CASCADE` on deployment_targets.agent_id silently wiped every target, orphaning certs and aborting in-flight jobs. The finding closure reshapes the agent-removal contract around soft retirement with explicit preflight counts, an opt-in cascade gated by a mandatory reason, and unconditional protection for the four reserved sentinel agents used by discovery sources. Schema — migration 000015: migrations/000015_agent_retire.up.sql flips deployment_targets_agent_id_fkey from ON DELETE CASCADE to ON DELETE RESTRICT, so a stray `DELETE FROM agents` now errors at the DB boundary instead of quietly destroying targets. Both `agents` and `deployment_targets` grow a retired_at TIMESTAMPTZ + retired_reason TEXT pair (TEXT not VARCHAR so operator comments are never truncated), indexed via partial indexes WHERE retired_at IS NOT NULL. The migration is self-healing (ADD COLUMN IF NOT EXISTS, DROP CONSTRAINT IF EXISTS then ADD CONSTRAINT, CREATE INDEX IF NOT EXISTS) so repeated runs against partially-migrated databases converge. migrations/000015_agent_retire.down.sql restores CASCADE and drops the new columns for clean rollback. A dedicated repository-layer testcontainers test (internal/repository/postgres/migration_000015_test.go) asserts the before/after FK action, column presence, index presence, and round-trip idempotency under up→down→up. Domain — sentinel guard + dependency counts: internal/domain/connector.go gains IsRetired() on Agent, the exported SentinelAgentIDs slice listing server-scanner, cloud-aws-sm, cloud-azure-kv, cloud-gcp-sm verbatim (matching the four reserved IDs documented in CLAUDE.md and created at startup in cmd/server/main.go), IsSentinelAgent(id string) predicate, AgentDependencyCounts{ActiveTargets, ActiveCertificates, PendingJobs} with a HasDependencies() method, and ActorTypeAgent / ActorTypeSystem enum values used by audit emission downstream. Coverage locked down by internal/domain/connector_test.go. Service — 8-step ordered contract: internal/service/agent_retire.go:RetireAgent(ctx, id, actor, opts{Force, Reason}) enforces a fixed execution order: (1) sentinel guard — IsSentinelAgent(id) returns ErrAgentIsSentinel unconditionally; force=true does NOT bypass it. (2) fetch — ErrAgentNotFound on miss. (3) idempotency — if IsRetired() already, return AgentRetirementResult{AlreadyRetired: true} with no new audit event and no state change (safe to replay from flaky clients). (4) preflight counts — collectAgentDependencyCounts runs ActiveTargets, ActiveCertificates, PendingJobs sequentially (not in parallel; keeps the per-query timeout predictable and matches the repo's existing call-chain shape). (5) force-reason guard — opts.Force=true with empty Reason returns ErrForceReasonRequired (wired into the 400 status surface). (6) dependency guard — HasDependencies() with opts.Force=false returns BlockedByDependenciesError{Counts} (wired into the 409 body with per-bucket counts). (7) mutation — single pinned retiredAt := time.Now(); agent retirement first, then cascade target retirement if opts.Force, all under the repo's single transaction so the two retired_at stamps match to the second. (8) best-effort audit — agent_retired always; agent_retirement_ cascaded additionally on the force path. Actor is whatever the handler resolves from the request; actor type is mapped by resolveActorType (system/agent-prefix→Agent/else→User). Audit emission failures are logged via slog.Error but do not abort the retirement (matches the house convention used by every other scheduler-emitted event). BlockedByDependenciesError implements Error() as "active_targets=%d, active_certificates=%d, pending_jobs=%d" and Unwrap() → ErrBlockedByDependencies. The single struct satisfies errors.Is via Unwrap (used by scheduler-level tests) and errors.As via the concrete type (used by the handler to fish out Counts for the 409 body). ListRetiredAgents(page, perPage) adds a separate paginated accessor with page<1→1 and perPage<1→50 normalization so retired rows are queryable without polluting the default agent listing. Sentinel guard coverage is asymmetric by design: all four reserved IDs are protected, and force=true cannot override. Regression tests in internal/service/agent_retire_test.go assert each of the eight steps in order, plus sentinel bypass attempts and idempotency replay. Handler + router — status-code surface: internal/api/handler/agents.go:RetireAgent exposes seven status codes on DELETE /agents/{id}: 200 on a fresh retirement (body echoes AgentRetirementResult). 204 on idempotent replay (AlreadyRetired=true; no new audit). 400 on ErrForceReasonRequired. 403 on ErrAgentIsSentinel. 404 on ErrAgentNotFound. 409 on BlockedByDependenciesError, with a custom body shape {error, counts{active_targets, active_certificates, pending_jobs}} that bypasses the default ErrorWithRequestID envelope so callers get the per-bucket numbers directly. 500 on any other error. Heartbeat HandleHeartbeat returns 410 Gone when the agent is retired (ErrAgentRetired), signalling the agent to shut down. Query params `force=true` and `reason=<text>` drive the cascade path; both are forwarded as url.Values through the new MCP transport. internal/api/router/router.go registers GET /api/v1/agents/retired literal-path BEFORE /api/v1/agents/{id} — Go 1.22 ServeMux's literal-beats-pattern-var precedence routes "retired" to the paginated retired-agents listing instead of fetching a hypothetical agent named "retired". Agent binary — clean shutdown on 410: cmd/agent/main.go gains the ErrAgentRetired sentinel, a retiredOnce sync.Once, and a retiredSignal chan struct{}. A markRetired(source, statusCode, body) helper closes the channel exactly once; the Run() select loop observes the close and returns ErrAgentRetired; main() matches via errors.Is(err, ErrAgentRetired) and exits cleanly instead of spinning in the heartbeat retry loop. The 410 Gone surface is therefore terminal for the agent process. MCP transport: internal/mcp/client.go adds Client.DeleteWithQuery(path, query), a new additive transport method. Client.Delete is path-only; without this method the retire tool would silently drop `force` and `reason`, turning every cascade retire into a default soft-retire. The new method shares do()'s 204 normalization and 4xx/5xx error propagation so tool authors get one contract. internal/mcp/tools.go + internal/mcp/types.go expose the retire_agent tool with Force+Reason inputs wired through DeleteWithQuery. CLI: cmd/cli/main.go + internal/cli/client.go add two CLI surfaces: `agents list --retired` (client-side strip of --retired then delegation to ListRetiredAgents, sharing --page/--per-page parsing with the default listing) and `agents retire <id> [--force --reason "…"]` (mirrors ErrForceReasonRequired — force without reason is rejected client-side before the request is sent). JSON + table output modes both honor the new columns. Frontend: web/src/pages/AgentsPage.tsx surfaces retired/retire affordances. web/src/api/client.ts + web/src/api/types.ts expose the retire endpoint and the retired-listing. 4 new Vitest regression cases. OpenAPI: api/openapi.yaml documents DELETE /agents/{id} with all seven status codes, 410 on heartbeat, and the 409 per-bucket body shape.

shankar0123	11173a74c6	feat(M31): agent work routing — scope jobs to assigned agents ... Deployment jobs now set agent_id from target→agent relationship at creation time. GetPendingWork() uses ListPendingByAgentID() with a 3-way UNION query (direct match, legacy NULL fallback via target JOIN, AwaitingCSR via cert→target→agent chain) so each agent only receives its own jobs. - Added AgentID *string to Job domain struct - Added agent_id to all job SQL queries (5 SELECTs, INSERT, UPDATE, scanJob) - New ListPendingByAgentID() repository method - Rewrote GetPendingWork() from ~25 lines to single scoped query - 4 new Go tests (3 agent routing + 1 deployment agent_id) - Frontend: agent_id/target_id on Job type Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-30 14:10:42 -04:00
shankar0123	e03a75ed9a	fix: replace fmt.Printf with structured slog logging across all services ... All 10 service files now use slog.Error for failure logging instead of fmt.Printf. Audit event recording errors are checked and logged rather than silently discarded. Adds consistent structured context (resource IDs, operation names) to all error log statements.
