Make background/long/desynced turns visible and queueable, fixing the four
symptoms that survived the v0.15.0 chat reliability pass.

F1 - status-driven working signal (workspace.ts taskWorking/currentWorking =
streaming OR status in {planning,executing}). Drives the chat trace, indicator,
and activity spinner so a turn with no live stream (background resume, a dropped
SSE, an idle-close mid long turn) still looks alive.

F2 - operator messages sent during an in-flight turn are now QUEUED and
auto-run when the gate frees, replacing the "still finishing a previous step...
send it again" rejection. Per-session in-memory FIFO (messagequeue.go, capped at
20) drained one-at-a-time under the turn gate; a `queued` SSE event drives a
"Queued" hint. drainQueued releases via a per-iteration deferred closure so a
runChatTurn panic can't deadlock the session's gate.

F3 - SSE keepalive (12s `:keepalive` comment) in handleChat so 20-40s
inter-iteration gaps no longer trip a proxy/browser idle close (the desync root
cause). All SSE writes serialized through one mutex.

F4 - generation-aware activity timeline (only the last propose_plan renders;
superseded ones collapse to one "Earlier plan revised" marker; step-attribution
follows only the current generation) + debounced plan refetch on lifecycle
events so a missed plan.proposed self-heals.

Verified against the last session (23da10db: 6m33s turn, operator "status"
deferred at 19:48:05). go test ./cmd/nomos/ green (new messagequeue tests);
web vitest 72/72 (new F4 generation tests); vite build clean.

39e9227fdb feat(nomos): per-session turn serialization + chat reliability/UX fixes
Some checks failed

The agent could run two turns for one session at once (a reconnect resumed
while the live turn was still going), and their interleaved tool calls
corrupted the activity panel, fabricated a confusing "parallel/nested"
sequence, and made tasks feel stuck/never-ending. Several UX gaps compounded it.

Turn serialization (F1):
- turnGate: at most one in-flight turn per session. Background resume paths
  (continuation worker, idle sweep, answer-question, /resume, reconnect)
  skip non-blocking when busy; the live chat path waits briefly then bails
  cleanly instead of stacking a second turn.
- resumeSession returns whether it ran; continueSession marks an execution
  "continued" only after a real run (review P0) so a busy-skip can't lose a
  finished-execution result. Idle nudge bumps only after delivery (P1).

Connection state (F2/F3, web):
- humanize/bucket raw errors ("model connection dropped..."); one surface
  per drop; a terminal task.status event clears stuck streaming/disconnected
  state and dismisses the connection toast. Reconnect no longer spawns turns.

Streaming where you look (F4, web):
- live command output in the global activity timeline and in the inline
  tool card (auto-opened, tail-pinned) -- not just the per-window rail.

Other (web): artifact/knowledge deep links (F5); step-first stable
"thinking" headline (F6); stable chat layout, no empty->content reflow (F7);
lazy event sync (P2.2); reconnect skips a terminal session (P2.1).

Session-review implementation for the three sessions audited in
plans/2026-07-18-session-review-three-sessions.md. v0.7.11 → v0.7.12.

P0.1 — retry cap + investigate-before-retry (cmd/nomos/retrycap.go,
agent.go): after 3 identical failing run calls in a single turn, refuse
to dispatch the call again and return a directive to investigate *why*
(ps/strace/lsof) or surface the blocker. Per-turn scope so a fresh turn
after the operator responds can retry once more. Session 1e9c7691's 20+
identical chown retries (knfsd held a kernel lock on the exported NFS
dir) is the direct motivation.

P0.2 + P1.8 + P2.10 — SOUL.md guidance: hung command is not a failed
command (investigate before retry); ask before proposing a multi-step
migration; multi-goal sessions summarize the arc not just the last goal.

P1.3 — two new runbook entities in seeds/knowledge.yaml:
  - nfs-exported-dir-mutation-hang (the knfsd fchownat lock procedure:
    killall → exportfs -u → mutate → exportfs -a → verify)
  - netbird-mgmt-oidc-race-after-upgrade (docker restart netbird-mgmt
    after ~30s for the traefik/authentik OIDC race)

P1.4 — setGoal emits task.superseded event when prior goal is overwritten
by a different goal (store.go, TestSetGoal_SupersededEvent). Session
55927f0a had two set_goal calls with the first silently abandoned.

P1.5 — inspect_path MCP tool: runs mount/df/ls/stat for one path across
up to 8 targets in one parallel call, replacing the 15+ run-call
fact-gathering fan-out sessions 1 and 2 each spent on cross-target path
tracing (tools.go, server.go: inspectPathAcrossTargets, inspectOneTarget).

P1.6 — vm: target support in run via qm guest exec (no more SSH-hop
with nested quoting). Extracted shared resolveProxmoxHostSlug for
LXC + VM, with hosts-relationship fallback when attributes.host is
absent (server.go, tools.go). Session 55927f0a's SSH-hop workarounds
for vm:zimaos are the direct motivation.

Deferred (documented in plan): P1.7 (approval window auto-extend on
timeout) and P2.9 (long-running command PENDING detection) — both
addressed at lower cost by the retry cap. Session 3's poll-after-timeout
pattern already works; the cap protects against the failure mode.

df24cae507 fix(agent): fully silent assent — no system notes, no chat_assent events
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
The len(pending)>0 path still injected a brief note saying 'execution(s)
are now running' — the model saw this, thought work was being done for
it, and no-op'd (finish_reason=stop, content_len=0). Same confusion as
the len(pending)==0 case, just from the other branch.

Fix: both assent paths are now fully silent. No system note at all. The
model sees 'go ahead' in the replayed history and responds naturally.

Also removed chat_assent tool_use/tool_result emit events. These were
persisted in the transcript and confused the model on replay — it saw
its own 'tool calls' (chat_assent) and thought it had already acted.

ca2ff56a25 fix(agent): mark chat-assented executions as continued to prevent race
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
When the chat handler approves a pending execution via chat-assent, the
execution completes in ~2s. The continuation worker detects the completed
execution and calls resumeSession — while the chat handler is still
processing 'go ahead'. Two concurrent LLM calls for the same session cause
empty responses (finish_reason=stop) and race conditions.

Fix: mark the execution as continued immediately after chat-assent grants
it, so the continuation worker skips it. The chat handler will drive the
continuation itself (the model sees 'go ahead' and executes the plan).

VERSION 0.7.2 → 0.7.3

d6e180845c fix(agent): silent assent — stop injecting confusing system notes
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
The assent pre-processing injected verbose system notes ('the operator
approved... they are now running... you MUST continue...') on top of the
replayed user message ('go ahead'). The model saw both, latched onto
'now running', concluded the work was being done for it, and no-op'd
(finish_reason=stop, content_len=0) — leaving the session stuck in
'executing'.

Root cause: the model already sees 'go ahead' in the replayed history
(the user message is saved to the DB before chat() is called, and
getRecentMessages replays it). The system note was redundant AND
confusing — it told the model work was 'running' when it wasn't.

Fix:
- len(pending)==0 (plan-proposal approval): open assent window silently.
  No system note. The model sees 'go ahead' and responds naturally.
- len(pending)>0 (actual pending executions): brief note naming the
  specific execution IDs that were approved ('don't re-request those').
  No 'continue the plan' directive — the model knows to continue.

e3b5fdc358 feat(agent): auto-complete tasks when all plan steps are terminal

Desktop App / Build Linux (amd64) (push) Has been cancelled

The #1 remaining model reliability gap: the agent does the work (proposes
plan, executes all steps, writes back) but forgets to call complete_task,
leaving the session stuck in 'executing'. The eval showed 3/8 failures
with this pattern.

Fix: autoCompleteIfPlanDone — a structural safety net that fires at both
chat exit paths (normal completion + maxIterations). If the session has a
goal, the agent didn't call complete_task, and ALL plan steps are in a
terminal state (done/failed/replaced/skipped/blocked), auto-complete with
the agent's final text as the summary. Mirrors autoCompleteTrivialTask
but for structured tasks where the work is provably done.

Also: bump maxLLMRetries from 2 to 3 (complex multi-turn flows benefit
from one more retry on empty responses).

Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
The assent system note said 'Do not re-request or call run again for
these' — the LLM interpreted this as 'don't call run at all' and produced
empty responses (finish_reason=stop, content_len=0) until retries were
exhausted, leaving the session stuck in 'executing'.

Fix: rewrite both assent notes (pending-approval path and pure-plan-approval
path) to be directive about WHAT TO DO NEXT: call update_plan_step(running)
then run for each remaining step. The 'don't re-request' guidance is now
scoped to 'THOSE SPECIFIC' executions, not all run calls.

Also bump maxLLMRetries from 2 to 3 — the empty-response flake on complex
multi-turn flows benefits from one more retry.

a8f04cc9e3 fix(agent): open assent window on 'go ahead' after propose_plan
Some checks failed

ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
The check len(lastAssistantCalls) == 0 was too restrictive — it only
fired when the assistant had ZERO tool calls. But propose_plan + pre-plan
research are tool calls, so the assent window never opened when the
operator said 'go ahead' after a plan proposal. The agent then tried to
execute config_mutation run calls without the assent window, they queued
for approval, and the turn deadlocked.

Fix: check len(pending) == 0 (no pending APPROVALS) instead of
len(lastAssistantCalls) == 0 (no tool calls at all).

e3fa6736c0 feat(agent): plan-first gate, iterative follow-ups, reasoning persistence
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
P1 plan-first: run handler refuses without propose_plan (structural gate,
not SOUL.md prose). Plan window decoupled from set_goal — config_mutation
auto-run only on operator approval (assent window). Closes the approval-free
config_mutation hole confirmed in session d0d562e0.

P2 iteration: reopenSession flips terminal→executing, marks prior plan steps
replaced, clears outcome. proposePlan excludes replaced from in-flight check,
bumps generation. A follow-up on a completed session starts a new sub-task
with a fresh plan — no more errPlanInFlight dead end.

P3 reasoning: accumulate per-iteration text into the persisted row instead
of overwriting with the last text event. Reload shows intermediate thinking,
not just the final summary.

P4 read-only allowlist: add find, tree, locate, systemctl list-timers/
list-unit-files/show, timedatectl, hostnamectl, systemd-analyze, rclone
ls/lsl/md5sum/check/cryptcheck. Fixes the find misclassification from
d0d562e0.

P5 eval harness: new assertion kinds (proposes_plan, plan_before_run,
plan_generations), multi-turn followups, fetch /sessions/{id}/plan. Four
manifests under evals/.

P6 SOUL.md: strip degenerate-case carve-out, add ITERATE step, update
set_goal guidance.

dd3076a23a feat(agent): close all post-fix remainders + golden eval harness (F.1-F.2, C.1-C.2, B.4-B.6, E.1-E.2)
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
Ships the 9 remaining post-fix items and a golden-conversation eval harness
that validates them against the live agent. All 4 evals pass.

SOUL.md (F.1, C.2, E.1):
- Consolidated three overlapping task-flow sections (MANDATORY TASK FLOW,
  'Every chat is a task', 'AFTER EVERY TASK: WRITE BACK') into one. ~50
  lines shorter. The operator's 'be more crisp' feedback.
- Added anti-patterns: don't re-execute on UI/sidebar complaints (C.2);
  don't re-run fleet-wide audits when same-day knowledge exists (E.1).
- Updated approval vocabulary in step 4 to match tasks.go (approved/yes/
  go/proceed/continue/ok/go ahead).

Tool-result strings (F.2):
- set_goal: tightened to 'Goal set. NEXT: pre-plan (read-only tools only).
  Then propose_plan. Do not call run.'
- update_plan_step: added '(Advance with update_plan_step + run; do not
  re-propose.)'

C.1 — completeTask rejects re-completion of a terminal session:
- Returns errTaskAlreadyComplete when status is already done/failed.
- The tool result directs: 'Task is already complete. Do not call
  complete_task again. If the operator pointed out a UI/sidebar
  inconsistency, fix it with update_plan_step...'

B.4 — Surface real model error text:
- chatWith's error event now includes finish_reason + refusal text:
  'Nomos returned an empty or unusable response (finish_reason=length).
  Retry or rephrase.' instead of generic 'empty response'.
- The resume-failed note already carried errText (B.3), which now has
  the real context.

B.5 — Back off between resume retries (4s, 8s):
- resumeSession now sleeps before attempts 1 and 2 (exponential backoff).
  A transient provider issue gets time to clear instead of 3 identical
  calls in 3 seconds.

B.6 — Don't persist the empty placeholder as a visible bubble:
- If a chat turn ends with no text and no tool calls (model empty-response'd
  and all retries failed), delete the placeholder row instead of persisting
  an empty bubble. The error was already streamed via done+error=true.

E.2 — list_lxcs last-audited hint:
- The list_lxcs result now includes last_audited_at — the most recent
  knowledge entry (tagged audit/update, or titled audit/update) linked
  via an 'about' edge. The agent can see 'nextcloud — last audited today'
  and skip re-running it.

Tool-call doubling bug fix (found by the eval harness):
- main.go + continue.go: the tool_use and tool_result events were both
  appending separate entries to the persisted tool_calls array, doubling
  every tool call in the transcript. Confirmed pre-existing (d9cdcee1,
  v0.3.x era). Fixed: tool_use creates the entry, tool_result merges the
  result into the same entry (matched by id). One entry per tool call.

Golden eval harness (cmd/nomos/eval/):
- A standalone Go program that loads YAML manifests of golden conversations
  + assertions, sends prompts to the chat endpoint, drains the SSE stream
  (keeping the agent's context alive), and scores structural assertions
  against the persisted transcript.
- 4 golden conversations covering: trivial read-only (degenerate case),
  plan + proceed (the original duplication bug), UI complaint (no re-exec),
  fleet audit (knowledge preferred over re-execution).
- Structural assertions only (tool-call sequences, plan steps, writeback,
  completion) — text quality is model-dependent and not scored.
- Run: go run ./cmd/nomos/eval -gateway http://localhost:8092 -manifest
  cmd/nomos/eval/evals/*.yaml  (~$0.10/run in OpenRouter credits).

Eval results (4/4 passed):
  trivial_readonly:              2 tool calls, no plan, no run
  plan_advances_on_proceed:     13 tool calls, propose_plan x1, writes back
  ui_complaint_no_rerun:        12 tool calls, propose_plan x1, writes back
  knowledge_preferred_over_rerun: 7 tool calls, search_knowledge x1, 0 run

Version 0.5.2 -> 0.5.3 (minor: eval harness + structural hardening).

337d577f00 fix(agent): refuse plan re-proposal + emit done on error (close divergence chain)
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Desktop App / Build Linux (amd64) (push) Has been cancelled
Desktop App / Attach to Release (push) Has been cancelled
Operator-reported bug: on 'proceed with the rest' the agent re-proposed the
plan, duplicating it in the sidebar. Root cause was a three-bug chain, not
one bug:

1. Trigger — model empty-response on 'proceed' (approval vocabulary didn't
   list 'proceed', so the agent wasn't sure it was approved and no-op'd).
2. Amplifier — chatWith emitted 'error' without 'done' on empty response
   (agent.go:370). The frontend's onComplete saw !receivedDone and
   misclassified the model failure as a network disconnect, calling
   handleDisconnect -> resumeSession.
3. Divergence — the reconnect note was generic ('report your state'), so
   the agent re-proposed + re-executed instead of advancing the plan.

Fixes (shipped, e2e-validated against the live agent on oikos-nomos-1):

- A.2: proposePlan refuses re-proposal once a step has started (returns
  errPlanInFlight). Drops the append-mode safety net (commit 5384499) that
  was the direct source of the sidebar duplication. The agent must advance
  with update_plan_step + run; the tool result directs it.
- A.1: proposePlan sets the 'generation' column on INSERT (migration 020
  added the column + frontend grouping, but the INSERT never wired it).
- A.3: propose_plan tool description restated as a crisp contract (ONCE,
  STOP and wait, REFUSES once a step started, advance with update_plan_step).
- F.3: approval vocabulary expanded to approved/yes/go/proceed/continue/ok/
  go ahead; propose_plan result string tightened to an imperative.
- B.1: chatWith emits 'done' after 'error' on every terminal path via a new
  emitError helper. The frontend now treats model errors as ended (not
  disconnected), so no auto-reconnect -> resumeSession fires.
- B.2: reconnect/resume note carries the operator's last message + an
  explicit 'advance the plan, do NOT call propose_plan again' directive when
  a plan is in flight. Wired into all 4 resume entry points (reconnect,
  /resume, idle-sweep, question-answer) via enrichResumeNote.
- B.3: resumeSession escalates the recovery note across its 3 attempts (final
  retry: 'pick the lowest-pending step, mark it running, call run — do that
  now') instead of 3 identical notes -> 3 identical empties.

Verification: TestProposePlan_RefuseInFlight replaces TestProposePlan_
AppendVsReplace. e2e conversations against the rebuilt container:
  conv2 ('proceed with the rest') -> 0 propose_plan calls, plan stayed at
    3 steps (was 6+ before), update_plan_step x5 + run x2 + complete_task.
  conv3 (full plan, 'go ahead') -> apt-get update on lxc:dns auto-ran under
    the plan window, update_entity_attributes writeback, clean complete_task.
  nomos logs show zero reconnect/resume entries for the plan-proposing
    sessions (the three-bug chain is closed).

Remaining (not in this commit): D.1 refuse complete_task without writeback
(next blocker), C.1/C.2, F.1/F.2 SOUL.md consolidation, B.4-B.6, E.1/E.2.

Phase 1 — crash recovery: SSE auto-reconnect + backoff, polling gate
during disconnect, connection banner with retry button, empty-response
retry 3x, non-terminal resume on empty response, persistent error cards.

Phase 2/4 — visibility + continuation: custom ExecutionStatus renderer,
approvals extracted on every tool_result (not just done), activity bar
with status/goal, SessionDigest live polling, Continue button.

Phase 3 — cleanup: complete_task auto-cancels orphaned approvals,
deletes assent/destructive window keys, propose_plan marks pending
steps as replaced, plan step seq-order enforcement.

Phase 5 — knowledge loop: list_lxcs state filter (active/destroyed),
SOUL.md unmissable writeback section, propose_plan validation nudge,
complete_task writeback check, upsert_knowledge about array support,
plan generation grouping in frontend, session approval count badge.

Retire request_execution — all mutations now route through run.
Updated SOUL.md, AGENTS.md, CLIENTS.md, skills, and agent system notes.

Migration 020: plan step generation column, audit_log session_id index,
nomos_plan_executions pending-approval index.

0c0f35a3a9 feat(web): split SPA from oikos binary, require auth on every route
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Phase 0 of plans/2026-07-12-wails-desktop-app.md. The control-room SPA
is no longer embedded (web/embed.go deleted); it's a standalone static
build served separately (make ui / make deploy-ui). The api process
adds CORS and drops the dev-open auth bypass — every route now needs a
real bearer token, including SSE (?token= query param, EventSource
can't set headers) and api's own /agent proxy to nomos (previously
unauthenticated by omission).

nomos was an unauthenticated client of api's /mcp and approval-decision
endpoints; closing dev-open would have broken it, so it now sends
Authorization: Bearer $OIKOS_MCP_BEARER_TOKEN on every call back to api.

SPA gets a runtime config module (config.ts) and a Config.svelte
first-launch/reconfigure page, reachable afterwards via a "Connection"
entry in the sidebar footer. Every fetch() in api.ts routes through
fetchWithAuth so the same build works same-origin (browser prod, Vite
dev proxy) or cross-origin (future Wails webview, remote access).

Six gaps found against the plan and the live Caddy topology while
implementing — documented in the plan's "Plan review" section, most
notably: api's own /agent mount was never behind combinedAuth (fixed),
and production's Authentik forward-auth needs a bearer-token bypass for
API routes that this repo's Caddyfile.oikos reference copy now has, but
the real dtoro/caddy-conf deploy does not yet.

Verified live: cross-origin static SPA + API, CORS, bearer auth, SSE
query-token auth, and localStorage persistence all confirmed working
in-browser. Full Go test suite and npm run build pass with no
regressions against the pre-change baseline.

de126daf43 feat(web): fold Events/Agent/Audit into EntityDetail; tag agent_activity with entity_id
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Events, Agent, and Audit were standalone read-only pages that never
cross-referenced the entity they related to. Fold them into EntityDetail
as entity-scoped cards (Agent activity, Audit trail) alongside the
existing Signals/Executions/Knowledge cards, and give the Signals card
real Ack/Mute/Resolve actions. Signals stays a standalone page since
it's the only one with cross-entity triage value (badge count, actions).

Also fixes the underlying reason those new cards would've stayed empty:
agent_activity rows were never tagged with entity_id at insert time
(cmd/nomos/store.go, internal/mcp/server.go), even though the column
and the API filter both support it. Added a best-effort resolver that
checks common tool-arg keys (target, entity_slug, slug, ...) against
the entities table.

3b9c75fa3f fix(agent): task completion safety net — stop tasks sticking at Running
Implements fixes 1-3 of plans/2026-07-11-task-completion-safety-net.md.
Confirmed live that 50/50 production sessions never reached a terminal
status because the model almost never calls complete_task, even for
trivial single-tool Q&A turns SOUL.md explicitly calls out as needing it.

- Inline safety net (agent.go): a session that never called set_goal never
  framed itself as a structured task, so its first plain-text turn-end IS
  the task ending — auto-complete it there instead of leaving status stuck
  at its creation default forever.
- Idle sweep (continue.go, new completion_nudges column): goal-bearing
  sessions that stall get one nudge, then auto-close with outcome=partial
  if the nudge goes unanswered, mirroring the pattern resumeSession already
  uses for a different stuck-session failure mode.

Fix 4 (backfill of the 50 already-stuck live sessions) is deliberately
separate — deferred until this is deployed and verified live, per the
plan's implementation order.

11c18e8956 perf(agent): cache the MCP tool list per client (F1)
Fix F1 of plans/2026-07-11-nomos-agent-code-review.md, the last item.
buildTools called listToolsFull (a tools/list MCP round-trip) at the start of
EVERY chat turn, including every auto-continuation resume — the tool list is
static for the lifetime of one MCP connection, changing only when the api
process re-registers tools (a restart, which this client already detects and
reacts to via reconnectLocked). Re-fetching it every single turn was
avoidable network+parsing work on the hot path.

mcpClient now caches the parsed tool list after its first fetch, guarded by
its own mutex (kept separate from the request-serializing mu so a cache
check never contends with an in-flight doRequest call). reconnectLocked
clears the cache — an api restart may have changed what's registered, so a
stale cache would be wrong, not just slow. fleetSnapshot's get_health_summary
call is deliberately left uncached — it's meant to be "as of now."

Since each session gets its own client (the per-session pool from the
concurrency work), this caches per-task-conversation rather than globally: a
task's FIRST turn still pays the round-trip, every turn after reuses the
cached list — which is exactly the case that mattered (long-running,
heavily-autonomous tasks with many auto-continuation resumes).

Verified live via the api's request log: a brand-new session's first turn
made 3 MCP calls (initialize, tools/list, get_health_summary); a second turn
on the SAME session made exactly 1 (only get_health_summary) — tools/list
correctly skipped.

This completes the implementation order in
plans/2026-07-11-nomos-agent-code-review.md — every A/B/D/E/F finding from
the review (excluding C1, explicitly deferred per operator instruction) is
now fixed, tested, and verified live.

c3901641d1 fix(agent): bound conversation history replayed to the LLM (A2)
Fix A2 of plans/2026-07-11-nomos-agent-code-review.md. chatWith replayed a
session's ENTIRE message history into the LLM's context on EVERY turn, no
windowing, no token budget — confirmed against a documented production case
(a single turn with 70 tool calls, messages up to 106KB). Every subsequent
turn of a long-running or heavily-autonomous task re-sent that ever-growing
history in full — a real cost/latency/eventual-context-limit risk for
exactly the tasks this system runs longest (many auto-continuation cycles).

Design call (flagged in the review as needing one before implementation):
a fixed-size window for LLM replay specifically, not the UI's own transcript
view. Simplest option that still keeps roughly the current task's working
context; a token-aware trim or LLM-summarize-on-drop are documented as
stretch options if 30 proves insufficient in practice.

- store.go: new getRecentMessages(ctx, sessionID, limit) — last `limit`
  messages in chronological order, plus whether older ones were omitted.
  getMessages (used by the UI's GET /sessions/{id}) is untouched and stays
  unbounded — the operator should still see a task's full history regardless
  of length; only what gets sent to the model is bounded.
- agent.go: chatWith uses getRecentMessages(sessionID, historyWindowSize=30)
  instead of the unbounded getMessages. When truncated, injects a system
  note telling the model explicitly that older turns exist but aren't shown,
  so it checks upsert_knowledge/search_knowledge rather than assuming
  something wasn't done just because it isn't visible.

New cmd/nomos/store_test.go: real Postgres integration tests (mirroring
internal/db/integration_test.go's throwaway-database pattern, guarded by
OIKOS_TEST_DATABASE_URL). TestGetRecentMessages_Truncation is the direct
proof for this fix (35 messages → 30 returned, correctly ordered,
truncated=true; 5 messages → all 5, truncated=false) — both cases run
against a fully-migrated database, not mocked. Also added
TestProposePlan_AppendVsReplace, closing part of the review's test-coverage
finding (E) by permanently regression-testing the earlier append-vs-replace
plan fix (commit 5384499), which had only been verified manually until now.

Verified live: inflated a real session to 42 persisted messages via direct
SQL, then continued it with a real chat call — the turn proceeded normally
(multiple real tool-call iterations, no crash, no context-length error);
nomos stayed healthy throughout. A3's incremental persistence separately
confirmed to have caught the 7 real tool calls made before the client
connection was cut, cleanly closing out both fixes' interaction.

a4ea542f3e fix(concurrency): per-session MCP client pool — removes cross-task tool-call blocking
Fix 3 of plans/2026-07-11-concurrent-task-execution.md, the throughput one.
nomos held exactly one *mcpClient for the whole process, shared by every
/chat goroutine. Its mutex was held for the full duration of each tool
round-trip, and `run` executes its SSH command SYNCHRONOUSLY inside that
round-trip (capped at up to 10 minutes) — so while Task A was mid-`run`,
every other task's tool calls, even a trivial get_entity, queued behind that
single lock. Tasks could think (LLM calls) in parallel but never act in
parallel.

The MCP server has no per-connection state to protect (newServer returns one
shared *mcp.Server instance whose handlers close only over the DB
connection pool, already safe for concurrent use) — the mutex existed purely
because the client reused one stateful transport session. So the fix doesn't
touch the server at all:

- New mcpClientPool (cmd/nomos/main.go): one *mcpClient per session id,
  created lazily (a real MCP initialize handshake) on first use and cached;
  session-less traffic (the ephemeral no-DB-store path, the structured
  /query endpoint) gets its own fixed, reused key instead of a fresh
  connection per request. Idle clients (20 min past last use — long enough
  to outlive a single slow `run`) are evicted on a 5-minute sweep ticker.
- agent.go: `client *mcpClient` → `clients *mcpClientPool`; every call site
  (buildTools, fleetSnapshot, the tool-dispatch loop) now resolves its own
  session's client via clients.get(sessionID) instead of reaching for one
  shared field. A task's own tool calls stay sequential (already true — the
  agent loop calls tools one at a time within a turn) but no longer block
  anyone else's.
- main.go: handleQuery takes the pool instead of a client (keyed "query", a
  fixed non-session slot); shutdown calls pool.closeAll().

Verified live against the deployed stack: fired a slow-but-ungated command
(`ping -c 15 127.0.0.1`, read-only per policy's allowlist, no approval
needed) as Task A, then — 2s into A's run — a trivial hostname lookup as
Task B, both through the real /chat endpoint. Task A's ping genuinely ran
~14.3s (confirmed via its own execution record and the agent's reported
output). Task B returned in 6s total, well before A finished — proving it
was never queued behind A's connection. Before this fix, B would have been
forced to wait out A's entire ~14.3s hold on the single shared client.

This completes plans/2026-07-11-concurrent-task-execution.md's required
scope — only the explicitly optional/deferred Fix 4 (a concurrency/cost cap,
pending real usage data) remains.

9ef1ba3702 fix(concurrency): scope assent/destructive windows to session, not just agent
Fix 1 of plans/2026-07-11-concurrent-task-execution.md — the safety-critical
one. The assent window (and destructive window) were keyed purely by agent
id ("assent_window.agent:<uuid>"). With one agent:nomos entity serving every
concurrent task, this meant approving Task A's plan opened a window that ANY
concurrently-running task's config-mutation/destructive actions could also
ride, auto-executing without their own approval.

- store.go / agent.go: assentWindowActive/openAssentWindow and
  destructiveWindowActive/openDestructiveWindow/destructiveWindowKey all gain
  a sessionID parameter; keys become
  "assent_window.agent:<id>.session:<sessionID>" and
  "destructive_window.agent:<id>.target:<slug>.session:<sessionID>". Missing
  session id fails closed (no window) rather than falling back to the old
  agent-wide key.
- continue.go: the auto-continuation worker's window check moved from once-
  per-batch to once-per-pending-item, scoped to that item's own session —
  it was previously checking ONE agent-wide window for a batch that can span
  multiple tasks.
- agent.go tool-dispatch: injects `_session_id` into a COPY of the wire args
  sent to the MCP server (never into the args used for the emitted/logged/
  persisted tool call, and never part of any tool's declared InputSchema —
  invisible to the model) so the gating checks on the OTHER side of the
  process boundary know which task is asking.
- internal/mcp/server.go: assentWindowActive/destructiveWindowActive/
  classifyAndGate gain the same sessionID parameter, read from
  args["_session_id"] at the three call sites (request_execution's
  apt_upgrade/pct_create branches, and the shared classifyAndGate used by
  restart/pct_exec/systemctl/run).

Verified against the live stack with the exact scenario from the plan: opened
an assent window for session A only, then called `run` with an identical
config-mutation command for session A (window open) and session B (same
agent, no window). A auto-ran (execution status completed); B correctly
queued for approval (pending_approval) instead of bleeding through — proven
at both the MCP response text and the executions table.

014e5c74e0 feat(tasks): phase 5 — ask_operator (structured question, pause, resume)
The last backend piece: when the agent hits a decision only the operator can
make, it surfaces a structured question instead of guessing or stalling.

- ask_operator(prompt, why?, options?, context_entities?): nomos-local tool
  that records a session_questions row, moves the task to awaiting_input, emits
  question.raised, and ENDS the turn (the agent loop returns after it, so the
  agent can't barrel past its own question). The prompt becomes the assistant's
  visible message so the question also shows inline in the transcript.
- Two resume paths, both close the question + emit question.answered + return
  the task to executing:
  - Panel: POST /sessions/{id}/questions/{qid}/answer → resumes the agent in the
    background with the answer injected (reusing the continuation machinery,
    refactored continueSession → resumeSession). Returns 202; the reply lands via
    message polling.
  - Chat reply: the next chat message on a task with an open question IS the
    answer — auto-closed in handleChat; the turn itself is the resume.

Verified end-to-end: forcing a decision paused the task at awaiting_input with
the structured question (prompt/why/options/entities); a panel answer resumed
the agent (it acknowledged host:strong and continued); a plain chat reply
auto-closed a second question. Cleanup + tests green.

532310bb4b feat(tasks): phase 3 — close the knowledge loop (complete_task + retrieval)
Adds the compounding knowledge loop the task model is built around:

- complete_task(outcome, summary): a nomos-LOCAL, session-scoped tool (the
  shared MCP server has no session id). Introduces the local-tool mechanism —
  buildTools appends task tools, the agent loop routes them to handleTaskTool
  instead of the MCP client. Sets the task's terminal status/outcome/summary,
  mirrors it onto the task entity, and emits task.status.
- Knowledge → task linkage: after a successful upsert_knowledge in a task,
  nomos links the note to the task entity (documents) and emits
  knowledge.recorded, so the task's outcome view shows what it learned. The
  note's about-link to the involved entity (written by upsert_knowledge) is the
  retrieval path future tasks use.
- SOUL: every chat is a task loop — retrieve prior knowledge FIRST
  (get_entity_knowledge on the target), plan, execute, record learnings, then
  complete_task. Scales down for trivial read-only tasks.
- deleteSession now cleans up the task entity, its relationships, and its
  task-scoped events (was orphaning them); the knowledge doc itself and its
  about-links survive, as knowledge should outlive the task.

Verified end-to-end: a task recorded a note and completed; task.status +
knowledge.recorded hit the SSE stream; status=done/outcome=success persisted;
the note linked to both lxc:caddy (retrieval) and the task; a future
get_entity_knowledge(lxc:caddy) surfaces it; delete cleaned edges+events (0/0/0)
while the knowledge survived.

3dba2e550a feat(tasks): phase 2 — entity.touched events + task→entity involves edges
As the agent runs a task, record which entities each tool call references:
write an idempotent task —involves→ entity relationship and publish one
entity.touched event per entity (correlation_id = session, data {slug,tool}).
Extracted from tool ARGS only — never results — so a bulk fleet query can't
drag every entity into the task graph; bulk/no-slug tools stay silent.

Emitted from the nomos agent loop rather than the shared MCP wrapper, which
has no session id. The involves edges make a task's graph neighborhood its
involved-entity set (queryable via get_relations) — the substrate for the
knowledge loop; the events are the live pulse the context panel consumes in
phase 6.

Verified end-to-end on the local stack: a chat referencing lxc:caddy/lxc:gitea
produced entity.touched on the browser SSE stream with slug+tool+correlation,
and exactly one involves edge per entity despite repeated touches.

60edff2065 feat: knowledge write-back (upsert_knowledge) + proactive outcome reporting
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
From the last (successful) TypeType deploy session, two gaps the operator hit:

1. Knowledge write-back — the missing half of the loop.
   The agent could read the knowledge base (search_knowledge/get_entity_knowledge)
   but had no way to WRITE it, so everything it learned (the Dragonfly memlock
   rlimit gotcha, the NAT-hairpin DNS issue, etc.) lived only in an ephemeral
   chat message and was lost — the system could never actually "get better."
   This is the `upsert_knowledge` MCP tool the 2026-07-08 gaps plan called for.
   - internal/mcp/server.go: upsert_knowledge(title, content, about?, tags?,
     kind?) writes a document/investigation/runbook entity + knowledge_entities
     row (search column is generated), upserts by slug so re-titling updates in
     place, and optionally links it to the entity it's about so
     get_entity_knowledge surfaces it there.
   - SOUL.md: capture non-obvious findings/deploys/gotchas as part of finishing
     work, not only when asked "what did we learn".

2. "I had to ask for status multiple times."
   The clearest cause: a long working turn (64 tool calls) that exhausted the
   iteration cap ended with a bare "max iterations reached without final
   answer" — a dead end that forced the operator to ask what happened.
   - cmd/nomos/agent.go: on exhaustion, make one final no-tools LLM call
     (finalSummary) asking for a status report — what was accomplished, current
     state, what remains — so the turn always ends with a real outcome.
   - maxIterations 25 -> 40 (the decomposed per-step pct_create flow legitimately
     needs more steps).
   - SOUL.md: always end a turn with a clear outcome; never end silently or on a
     bare tool call — the operator can't see the tools working and reads silence
     as "nothing happened".

2e922f6421 feat: decompose pct_create into atomic create + agent-driven install; add scoped destructive window
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Closes the two remaining open points from the auto-continuation work.

1. Atomic pct_create (observability, the bigger of the two):
   pct_create used to bundle create + apt install + post_install script into
   one black-box multi-minute SSH call — the agent got back a single opaque
   success/fail with no way to see (or fix) which step actually broke.
   Removed the whole post-create provisioning block (and the now-dead
   provisionScript/sanitizePkgs helpers + their tests). pct_create is now
   create + start + register ONLY — fast, and its result is fed back to the
   agent via auto-continuation almost immediately. The agent installs
   packages and runs setup as its OWN sequence of `run` calls against the new
   lxc:<hostname>, observing each command's real output and able to diagnose
   and retry exactly the step that failed — the same recovery loop already
   proven for the general case, now applied to installs too, instead of
   requiring a separate black-box mechanism.
   - services/post_install removed from the pct_create params struct and
     from the MCP tool schema/SOUL.md docs.
   - SOUL.md: explains the new flow, moves the Docker CLI gotcha and DNS
     troubleshooting guidance to be steps the agent runs itself.

2. Scoped destructive window (targeted autonomy for recovery):
   Verified live in the previous session that a destructive recovery (a
   failed destroy needing stop-then-destroy on the same container) required
   TWO separate typed confirmations for what was clearly one recovery
   action. Added a narrow, TARGET-scoped 15-minute grant
   (destructive_window.agent:<id>.target:<slug> in autonomy_settings,
   shared key format across cmd/nomos and internal/mcp) that opens only
   after an EXPLICIT typed confirmation (never loose assent) or an explicit
   button-approval of a destructive step, and only ever covers further
   destructive commands against that SAME target. A different target always
   needs its own fresh confirmation — this narrows risk instead of loosening
   it globally, unlike broadening the general assent window to cover
   destructive actions would have.
   - cmd/nomos/store.go: openDestructiveWindow/destructiveWindowActive/
     executionTarget.
   - cmd/nomos/agent.go: opens the window when a typed confirmation grants a
     destructive chat-assent execution.
   - internal/mcp/server.go: `run` tool checks the window before gating a
     destructive command; auto-runs if active.
   - internal/httpapi/phase3.go: DecideApproval opens the same window when a
     destructive execution is approved via the button/API, for parity with
     the chat-assent path.

d2f749d33d feat: event-driven auto-continuation — agent runs an approved plan to completion
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
The root cause behind "the agent stops at the first error and doesn't recover":
provisioning executions run ASYNCHRONOUSLY (pct_create fires the SSH work in a
goroutine and returns "running" immediately), so the agent's turn ENDS before
the result exists. The agent literally isn't running when the step fails — it
can't react to a failure it never observes. The only thing that fed results
back was the operator typing "continue" after every async step: the human was
the event loop. (In the flagged 18-message session the operator typed
continue/proceed/?? eight times while the agent correctly diagnosed each failure
but couldn't advance a step on its own.)

This makes the system the event loop instead:

- migrations/017: nomos_plan_executions links each gated execution to the chat
  session that started it.
- cmd/nomos: after a tool result, any "execution <uuid>" it started is linked
  to the session. A background worker (continue.go) polls for those executions
  reaching a terminal state and — while the agent has an open assent window (an
  approved plan is in flight) — re-invokes the agent with the result
  ("execution X completed/failed: <result>"), so it proceeds to the next step
  or diagnoses+fixes the failure, with no operator tick. Guarded against loops
  (mark-continued before running) and bounded by the 30-min window.
- chatWith(): chat() variant that injects the finished-execution note after
  replayed history without persisting a fake user turn.
- DecideApproval: approving a step by ANY route (button or chat-assent) now
  opens the assent window, so auto-continuation works regardless of how the
  operator approved — previously only typing "go ahead" opened it.
- SOUL: the agent is told it will be auto-re-invoked when async steps finish —
  don't poll get_execution_status, don't wait for "continue"; end the turn and
  keep going step by step until the goal is verified or a genuine blocker.

This is the root fix, not another per-command patch: you can't enumerate every
failure of an unbounded action space, but you can give the agent a loop that
observes each result and adapts — because "do anything" always includes "the
first attempt failed."

c3699157ae fix: chat-assent chicken-and-egg + agent stops after errors
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Three fixes for the session where the agent proposed a plan, waited
for 'proceed', then re-queued instead of being auto-approved:

1. Chat-assent fallback: when the operator says 'proceed' but the
   preceding turn had NO pending approvals (agent proposed plan in text
   without calling request_execution), inject a system note telling the
   agent to execute the plan now. Opens the assent window so subsequent
   config_mutation commands auto-run.

2. SOUL.md: instruct agent to ALWAYS call request_execution/run when
   proposing a plan, not wait for 'proceed' first. This ensures a
   pending approval exists for chat-assent to grant.

3. SOUL.md: stronger Docker instructions — Debian 13's docker.io package
   installs the daemon but NOT the docker CLI binary. Must use
   get.docker.com in post_install. Added 'handling errors' section:
   diagnose, try alternatives, continue — don't stop after one failure.

657e1a8be1 feat: assent window + compound read-only classification + continue-after-approval
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Agent stopped after every approval step, forcing operator to type
'continue' 7× per deploy session. Root causes and fixes:

1. Compound read-only commands (e.g. 'systemctl status; journalctl')
   defaulted to config_mutation — now splits on ;/&&/||/| and classifies
   as read_only if all segments are inspection verbs. Added grep, wc,
   sort, uniq, cut, tr, dpkg -l, apt list, docker stats to allowlist.

2. curl|sh was classified destructive, forcing typed confirmation for
   legitimate installs (get.docker.com). Demoted to config_mutation —
   loose assent grants it, no typed phrase needed.

3. SOUL.md said 'STOP after queuing' — replaced with 'continue working
   on non-blocked steps'. Added assent window section instructing agent
   to carry out the full plan after approval.

4. Assent window: when operator approves a plan via chat assent, a
   30-minute window opens where config_mutation commands auto-run
   without re-approval. Agent writes expiry to autonomy_settings; MCP
   run tool checks it before gating. Destructive never auto-runs.

5. System note after approval now says 'CONTINUE executing the full
   plan — do not stop and wait for continue.'

f936098364 fix: approval UI was never mounted; add typed confirmation for destructive
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Root cause of "chat gave me no further feedback — had to go to Ops": two
compounding bugs, found by reading the actual production session transcript.

1. InlineApproval.svelte — all of last session's live-status/self-heal work —
   was never imported or rendered anywhere. Chat.svelte had its own separate,
   much dumber approval bar (no status tracking, no destructive handling, just
   silently disappears after clicking) that WAS the one users actually saw.
   Deleted the dead bar and its state; InlineApproval now renders per-message.

2. chat.ts's extractApprovals hardcoded `tool.name === 'request_execution'`,
   so any approval raised by the newer `run` tool was invisible — no card, no
   feedback, nothing to self-heal, forcing the operator to the Ops page with
   zero acknowledgement in the conversation. This was the actual proximate
   cause of last night's destroy-135 session. Fixed to match on response
   shape, not tool name, so it doesn't silently break again for the next new
   gated tool.

3. Nomos was telling operators "type something like 'I confirm destroy 135'"
   for destructive actions (SOUL.md) but no backend path ever consumed that
   phrase — chat-assent explicitly (and correctly) excludes destructive from
   loose assent, but I never built the alternative. Added
   isTypedConfirmation() (cmd/nomos/assent.go): stricter than loose assent,
   requires an explicit "confirm" statement, only applies to destructive-
   flagged pending approvals.

4. InlineApproval's completed-state hardcoded "Provisioned successfully" —
   wrong/confusing for a destroy or arbitrary `run` command. Now says
   "Completed on <target>" and shows the actual command output, verified live
   against the real destroy-135 execution.

Verified live in a real browser against the production API/DB (dev server
proxying to :8090): the historical stuck session now retroactively renders
both executions as resolved with correct wording and real output.

  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.

b37f85ae08 fix: make Nomos actually provision LXCs from chat (pct_create + web fetch)
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
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.

49c37fe8b1 fix: chat session reliability, cost, and hygiene (empty-response guard, tool truncation, delete, titles)
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
- 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

279549c8c9 fix: scheduler wrote health/metrics/events to probe entities, not targets
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.

e8e230b4a5 nomos+web: streaming, provider routing, event gap-fill, embedded UI; fix approval FK & session context
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Agent (cmd/nomos):
- Stream LLM tokens via NewStreaming; emit text_delta then final text.
- OpenRouter provider routing: data_collection=deny (ZDR) + require_parameters;
  NOMOS_PROVIDER_SORT opt-in; Exacto via model suffix.
- Multi-turn: reload session history into context; UI passes session id.
- Fix agent_activity logging (agent_id/session_id) and mcpClient data race.

Events (live control-room feed):
- approval.created (mcp), approval.decided (api), execution.completed/failed
  (approved-action path), signal.raised/resolved + health.changed (scheduler,
  transition-gated).

Fixes:
- createApproval FK violation (reuse execution entity) — the agent's only
  write path; log the previously-swallowed errors.

Web UI:
- Embed web/dist via //go:embed (single binary); Dockerfile builds SPA into
  the Go stage; committed .gitkeep placeholder keeps backend-only builds green.
- Caddy: Authentik-gated /agent/* -> nomos so the UI reaches the agent
  same-origin in production.
