Found live: `run` against lxc:caddy failed with "missing pve_id" even though
pve_id=121 was present — caddy is an inventory-seeded LXC with no `host`
attribute at all (only pct_create-provisioned LXCs set one). The combined
query scanned attributes->>'host' (SQL NULL) into a plain Go string, which
errors the whole Scan — including the pve_id column that scanned fine.
COALESCE the host column to '' so a missing host attribute degrades to the
documented default instead of failing the whole resolution.

Implements the first slice of plans/2026-07-10-general-gated-execution.md:
Nomos gets one general execution tool instead of only a fixed action enum,
gated by an automatic risk classifier, and approval can be granted by the
operator just replying in chat instead of clicking a button.
- internal/policy/command.go: ClassifyCommand(cmd, declaredRisk) — rule-based
read-only allowlist + destructive denylist, default-escalate to
config_mutation for anything else. Classification can only ESCALATE the
caller's declared risk, never de-escalate it (destructive always wins even
if declared read_only). Compound commands (&&, ;, |, $()) never qualify for
the read-only fast path. Full test corpus.
- internal/mcp/server.go: new `run` MCP tool — target (host:/lxc:), command,
purpose, optional declared_risk. Read-only commands execute immediately;
everything else queues an approval exactly like pct_create today, executed
via httpapi's existing executeApprovedAction. Also fixes a real latent bug:
pct_exec resolved an LXC's host attribute without the "host:" prefix, so it
could never find the Proxmox host — new resolveExecTarget/resolveRunTarget
helpers (mcp + httpapi) fix this for both the new `run` action and existing
actions that route through the same execution path.
- internal/httpapi/phase3.go: "run" case in executeApprovedAction; fixes two
bugs found while wiring this up — (1) DecideApproval hardcoded risk_class to
'config_mutation' on every approve, silently corrupting the audit ledger for
every other risk class; (2) denying/revoking an approval never updated the
linked execution's status, so it stayed 'pending_approval' forever instead
of reflecting the decision.
- cmd/nomos/assent.go: deterministic (not LLM-judged) chat-assent detection.
Scoped to the immediately-preceding assistant turn's pending approvals only
— an old "yes" can't retroactively approve something new. Destructive-risk
actions are excluded from loose assent. Approves via the same HTTP decision
endpoint the UI button calls, so both paths share one audit trail.
- web/.../InlineApproval.svelte: self-healing poll — a pending approval card
now picks up being decided via ANY path (chat assent, Ops page, Matrix), not
just its own button. Previously the banner stayed stuck showing
Approve/Deny even after the action had already run elsewhere.
- nomos/SOUL.md: `run` is now the general capability ("no fixed menu, only a
risk gate"); documents chat-assent behavior and the destructive exception.

The final "UPDATE executions SET result=$::jsonb" built its payload with
fmt.Sprintf and only escaped newlines. apt/pct output contains quotes,
backslashes and control chars, so the payload was invalid JSON, the jsonb
cast failed, and the (unchecked) UPDATE was silently discarded — the
execution stayed 'approved' with a NULL result even though the LXC was fully
provisioned (verified live: vmid auto-assigned, container running, service
installed, post_install ran).
- executeApprovedAction: marshal result via json.Marshal; log UPDATE errors
- add jsonErr() helper; route all pct_create failure-path results through it
- mcp/server.go: add jsonOut() for restart/systemctl/pct_exec inline results
- regression test for JSON validity on quote/backslash/control-char output

Root cause of "asks permission but never acts": the approved pct_create
execution failed to parse because the LLM emitted `"privileged":0` /
`"nesting":1` (numbers) into strict `bool` fields, so the container was
never created. Compounded by a hardcoded template name (debian-13.0-1)
that no longer exists on the host, and no way for the agent to read the web.
- flexBool: accept 0/1, "true", bool for privileged/nesting (the exact prod failure)
- pct_create template pre-flight: list host cache, validate/auto-pick newest debian
- pct_create services[] + post_install: one approval provisions a working service
- new http_get MCP tool (sanitized, size-capped, SSRF-guarded) — agent can read repos/sites
- request_execution description: target=host, full JSON schema + example
- SOUL.md: agent CAN fetch the web; prefer one-step provisioning
- default model deepseek-v4-flash -> v4-pro; maxIterations 15 -> 25
- unit tests for flexBool, template resolve, pkg sanitize, HTML sanitize + SSRF block
Verified live on host:strong with a throwaway VMID 999: template auto-resolved,
container created + booted, services installed, post_install ran, then destroyed.

- Execution entity name now includes UUID suffix: 'pct_create on host:strong (abc12345)'
so the (type,name) UNIQUE constraint doesn't block subsequent executions for the
same target+action. Dedup now uses JOIN + LIKE prefix match to find only
pending_approval executions.
- Move persistent approval bar from top of messages area to just above the
chat input box (bottom-fixed position, above the textarea form).
- Add dedup in request_execution: check entities(type,name) uniqueness before
creating duplicate executions. Returns 'already queued' message to the LLM,
preventing tool-calling loops.
- Fix createApproval JSON payload: use json.Marshal instead of fmt.Sprintf
to escape params (could contain unescaped double quotes from JSON config).
- Add ON CONFLICT DO NOTHING to entity/execution inserts for dedup race safety.
- Persistent approval bar at top of Chat.svelte: aggregates pendingApprovals
from all messages, fixed position (won't scroll away). Approve/deny/approve-all.
- Update SOUL.md: agent must STOP after queuing a gated action.
- Fix ToolCallGroup reactivity: wasActive = (active).
- Empty/refusal responses retried once, then surfaced as errors instead of silent blanks
- Chinese refusal boilerplate detected via denylist + non-ASCII heuristic
- Bulk-tool preference added to SOUL.md (list_lxcs over per-entity get_lxc_state)
- Tool results truncated to 4KB on persist; get_state_snapshot filters null-state entities
- Session delete (DELETE /sessions/{id} + confirm-on-second-click UI)
- Session titles auto-generated from assistant answer instead of raw user message
Problem: every host/service/lxc/etc. entity_status row was permanently
stuck at 'unknown' since creation. Verified against the live DB:
metric_samples had 17,559 rows, 100% attached to type='check' probe
entities and 0% to any real monitored entity; only 25 check entities
ever had real health written. check_defs.entity_id (the probe's own
bookkeeping entity) and check_defs.target_id (the host/service actually
being observed) were both real fields, but the scheduler wrote
UpsertEntityStatus/InsertMetricSample/emitSchedulerEvent keyed by
entity_id instead of target_id — so every check ran and every result
was real, it just landed on the wrong row. This is the mechanism behind
observed drift: the agent's dashboard/health tools reported the
internal probes' state, never the actual fleet.
Change:
- scheduler.go: runCheck/resolveSignal now resolve targetID from
cd.TargetID (falling back to the check's own id if unset) and write
status/metrics/events there. Signals stay keyed by the check entity,
unchanged, matching their existing resolution logic.
- Added a staleness sweep to housekeeping(): an entity whose last
observation is older than 3x its fastest enabled check's interval
(floor 5m) is marked 'stale' and emits health.stale, so a stalled
scheduler or disabled check_def can no longer look like current data
forever.
- migrations/016: deletes the now-orphaned check-entity entity_status
rows so dashboard/fleet-health rollups stop double-counting probes as
monitored entities. Historical metric_samples on check entities are
left as-is (time-series data, not safe to reattribute).
- openapi.yaml + regenerated gen code: Entity gains health/last_check_at;
'stale' added to the health enum everywhere it's used.
- dashboard.go / GetFleetHealth / nomos's get_health_summary MCP tool:
exclude type='check' entities from rollups.
- nomos/agent.go: replay prior turns' tool_use/tool_result pairs into
the conversation instead of dropping them (previously only final text
was replayed, forcing the agent to re-derive fleet state every turn),
and inject a compact live fleet-health snapshot into the system prompt
each turn so it starts oriented instead of spending an iteration on
discovery.
Risk: config_mutation (schema-adjacent — new migration, no destructive
DDL, additive DELETE only on orphaned rows). No behavior change until
oikos-api/oikos-scheduler/nomos are rebuilt and redeployed.
Verification: go build/vet clean across the repo. Ran this worktree's
own API binary against the live dev Postgres on an alternate port
(read-only from the live containers' perspective) and confirmed
/api/v1/entities now returns health/last_check_at, and the dashboard
health rollup dropped from double-counting to an honest 168 unmonitored
entities (matches reality pre-deploy — the live scheduler hasn't run
the fixed code yet). Confirmed check_defs.target_id correctly maps
multiple checks to host:hubris via direct psql query.

Plan #5 done. Wiki already archived to archive/knowledge/. seeds/knowledge.yaml
has 24 docs + 6 investigations + 3 runbooks.
- MCP search_knowledge: upgraded from ILIKE to PostgreSQL ts_rank/ts_headline
- MCP get_entity_knowledge: new tool, walks relationship edges to return
all docs/investigations/runbooks linked to an entity
- HTTP endpoints (SearchKnowledge, GetEntityKnowledge) already used full FTS
- Plan index + audit cross-reference updated
- phase3.go: RequestExecution now calls InsertEntity before InsertExecution
(executions.entity_id references entities.id via FK constraint).
- mcp/server.go: request_execution MCP tool same fix — inserts entities row
with slug 'exec:<target>:<id8>' before executions insert.
- docker-compose.yml: fix seed OIKOS_SEEDS_DIR from /app/seeds to /seeds
(distroless image COPY destination).
Reviewed the phase-2 implementation (parts 2–5) end to end. The suite hung
for 600s and several handlers were never exercised because there were no
tests for the new mutation/event/MCP surface. Fixes:
- CRITICAL: sseListener ran on context.Background() and held a pooled
connection forever, so pool.Close() deadlocked (600s test timeout).
NewHandler now takes a ctx that governs the listener; ListenAndServe and
the test helper cancel it before closing the pool.
- CRITICAL: MCP AddTool panicked ("missing input schema") at construction
under go-sdk v1.6.1 — so NewHandler (and every API handler) panicked.
Added object input schemas to all 8 tools via an objSchema helper.
- HIGH: PatchEntity parsed lifecycle transitions as map[string][]string but
the shape is {from:{to:{requires:[]}}}, so every state-change PATCH 500'd.
Parse the nested shape; allow same-state no-ops.
- HIGH: CreateEntity bound SQL NULL for attributes when omitted, violating
the NOT NULL column (the default only applies when omitted). Default to
'{}'.
- MED: serveSSEWriter ignored the request ctx (per-client goroutine leak on
disconnect) and set an invalid Content-Length: -1. Thread ctx through;
omit the header. writeSSE now nil-checks the flusher (io.Pipe path passed
nil → would have panicked on first event).
- MED: SSE `data:` leaked raw sqlcgen.Event (PascalCase, base64 JSONB).
Emit canonical gen.Event so SSE matches GET /events. Verified live.
- LOW: CreateEntity uses uuid.NewV7 (ADR-0005) + real actor from context in
audit; removed dead bearerAuth; fixed vet unkeyed-field warnings.
Tests (would have caught all of the above): entity create/patch with
If-Match 409/400, valid+invalid lifecycle transitions, idempotency replay,
duplicate-slug 409, abstract-type 422, event+audit side effects, MCP tool
registration. Live smoke test confirmed NOTIFY→listener→SSE delivery.
Also adds the missing Phase 2 deliverable: Gitea Actions CI (vet,
golangci-lint, govulncheck, generated-code drift guard, race tests against
TimescaleDB, docker build) and wires sqlc into `make generate`.
