Root cause of "running for 10+ minutes without stopping": a real production
execution (TypeType pct_create) was found genuinely stuck 17+ minutes into a
single blocking SSH call. The container's post_install script was looping on
`getent hosts deb.debian.org`, waiting on a network that could never come up
— the operator's static IP config used gw:192.168.8.1, but the actual gateway
on that subnet is 192.168.8.2, so every network call hung instead of failing
fast (packets dropped, not rejected).
Two compounding bugs made this unrecoverable without manual intervention:
1. sshExec (both internal/httpapi/phase3.go and internal/mcp/server.go) had
NO execution timeout — `session.CombinedOutput()` blocks until the remote
command exits, with no deadline. A hung remote process blocks the Go
goroutine forever; the execution can never leave 'running', and the
operator has no way to make it stop. Fixed: both now race the SSH call
against a 10-minute hard timeout, closing the session/client and
returning a clear "timed out after 10m0s" error if exceeded. (The
mcp/server.go copy also still had the original "swallowed non-zero exit"
bug from before that fix was applied to httpapi's copy only — fixed here
too.)
2. provisionScript's DNS-wait loop assumed `getent hosts` fails fast on no
connectivity — it doesn't; a black-holed network can make each call hang
far past the resolver's nominal timeout, so the documented "~90s" budget
was never real. Wrapped every attempt in `timeout 3` so the wall-clock
budget is now actually enforced (~2min worst case), and the failure
message now suggests checking the net0 gateway.
Also fixes the matching UI-side gap (operator's literal question: "is there
a way to get more details? it has been running for 10+ minutes without
stopping"):
- InlineApproval's track() polling loop had its own ~6min ceiling and simply
STOPPED polling after that — silently going stale before the backend (now
correctly capped at 10min) could ever resolve. Raised to a 14min ceiling
with margin, and added a distinct 'stalled' state if that's ever exceeded
(explicitly says something's wrong, rather than freezing silently).
- The running-card now shows live elapsed time (ticking, from the
execution's created_at), the actual command being run, and the execution
ID — previously just a static "this can take a minute" with zero
information. Also added command display to the destructive pending-
approval card for full transparency before confirming.
Verified live end-to-end in a real browser (dev server proxying to
production): queued a real command via chat, approved via the button,
watched the elapsed-time counter tick in real time, and saw it transition to
a completed card with real output once the command finished.

Live testing hit `entities_slug_key` violations: exec slugs used an 8-char
prefix of a UUIDv7, whose leading bytes encode a millisecond timestamp — two
executions created seconds apart can share a prefix. Use the full UUID
(guaranteed unique) for the exec entity's slug/name in request_execution, the
new `run` tool, and the REST RequestExecution handler — all three had the
same pattern.

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`.
