52e16e04ca feat: Learning page — capability timeline + trend, built on real data
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
The plan's "learning view" (runbook success-rate trends, promoted
skills, capability timeline) assumes the patterns/skills/feedback
pipeline is populated. It isn't: all three tables are empty in
production and nothing in the codebase ever writes to feedback, so
building the UI against them today would ship a permanently-empty
page. Scoped instead around data that's real and growing —
executions — while still wiring up /patterns and /skills so the page
needs no rework once that pipeline exists.

New /api/v1/learning/timeline (per-verb first-success date + success
rate, parsed via the existing splitAction helper) and
/api/v1/learning/trend (30-day daily success/fail counts), both
read-only queries against executions. Patterns and skills sections
call the existing (untouched) ListPatterns/ListSkills endpoints and
render an explanatory empty state instead of nothing.

6192c35c10 fix: close approval bypass in restart/systemctl/pct_exec
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Found live: a chat request to restart caddy (the reverse proxy for the
whole fleet) executed instantly over SSH with zero approval. Root
cause was in request_execution's legacy handler — restart, pct_exec,
and systemctl (outside enable/disable) executed immediately with a
hardcoded risk_class='reversible_low' that was never actually checked
against anything, bypassing the classifier entirely. Only the `run`
tool's commands were ever gated.

Extracted the run tool's classify -> execute-or-queue logic into a
shared classifyAndGate() and route restart/pct_exec/systemctl through
it too, so every mutating path — regardless of which tool the model
reaches for — gets the same read-only/config-mutation/destructive
classification and approval gate. systemctl restart is already covered
by an existing classifier test (config_mutation), so no new test
needed; the gap was that request_execution never called the
classifier at all.

682326382e feat: surface blast radius on approval cards
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Pending-approval cards showed target and risk but not what else the
action would affect — the operator approved config_mutation/destructive
commands blind to downstream impact, even though the graph-walk
(blast_radius() SQL, GetBlastRadius endpoint) already existed and was
just never wired into the approval path.

Fetch it once per pending approval and render "Affects N downstream: …"
on both the normal and destructive approval cards, reusing the existing
fetchBlastRadius() API client function which was already written but
unused anywhere.

ac48390796 feat: global activity feed + session digest
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Ops "Executions" tab showed raw target UUIDs, alphabetical (not
recency) order, and a stale status vocabulary from an earlier schema
iteration — never actually usable as a live "what's happening" view.
Replaced with a new recency-ordered /api/v1/activity/recent endpoint
and matching table (human-readable action summaries, risk/status
badges, duration, inline error preview).

Also added /api/v1/activity/session/{id} + a collapsible SessionDigest
panel in the chat rail, answering "what did this session actually do"
(executions by status, entities touched, knowledge written) — the
missing piece for proactive outcome reporting to be visible in the UI,
not just in the chat transcript.

40999b0b40 fix: knowledge/recent returned empty items — timestamptz couldn't scan into string
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Verified live immediately after deploying: the endpoint returned 200 with
correct-looking stats (total=56, agent_authored=2) but items=[] always,
regardless of limit/source. Root cause: pgx v5 can't scan a timestamptz
column directly into a Go string — Scan() errored on every single row, and
that error was silently swallowed by a bare `continue`, so every row was
dropped with no trace in the logs. Fixed by casting updated_at::text in the
SQL (matching how every other handler in this codebase already returns
timestamps) and logging scan failures instead of swallowing them, so this
class of bug can't hide silently again.

ec41c0b828 feat: learning view — make the growing knowledge base visible
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
First slice of the observability/learning UI (the "see the system come alive
and learn" ask). The Knowledge page was search-only — blank until you typed —
so the knowledge Nomos now writes via upsert_knowledge was invisible unless
you knew to search for it. Now the page LEADS with what the system knows and
is learning:

- internal/httpapi/knowledge.go: GET /api/v1/knowledge/recent — recency-ordered
  knowledge + a stats header (total, agent-authored, learned-this-week,
  by-kind). Custom route (not OpenAPI-generated), same auth as the rest.
- web Knowledge page rewrite: stat cards up top (Total / Written by Nomos /
  Learned this week / runbooks-investigations), then a "Recently learned" feed
  with agent-authored notes highlighted and badged "learned by Nomos", tags,
  and relative timestamps. A toggle filters to Nomos-only. Search still works,
  now as a mode you enter/clear rather than the whole page.

This turns "the system is getting smarter" from a claim into something you
watch fill up: every gotcha the agent records shows here within seconds.

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".

233b5e4519 feat: live visibility into what the agent is running (no more silent waiting)
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Operator: "I'd like to be able to see in the chat what the agent is actually
running, right now I just wait while nothing happens." Two compounding gaps:

1. The auto-continuation worker (cmd/nomos/continue.go) had zero live push —
   its result only appeared on a manual page reload, so approving a plan and
   watching the chat looked completely dead even while the agent was actively
   working.
2. Even with polling, continueSession only persisted ONE message at the very
   end of a continuation — a continuation that runs several tool calls before
   concluding would still show total silence for however long that took.

Fixed both:
- web/src/lib/stores/chat.ts: polls the current session's messages every 3s
  between turns (never while a live stream owns the message list) and merges
  in anything new. Started after a live turn ends and when a session loads;
  stopped on new-chat/session-switch.
- cmd/nomos/store.go: insertMessageReturningID/updateMessage — lets a message
  be created as a placeholder and updated in place.
- cmd/nomos/continue.go: continueSession now inserts a placeholder the
  instant it starts (renders as the existing "thinking" dots — immediate
  feedback that something is happening) and updates that SAME row after
  EVERY tool call, not just at the end. A poll within ~3s of any tool call
  landing shows it — individual `run` commands appear as the agent issues
  them, not just the final rolled-up summary.

13458e467c fix: the actual root bug — assent-window auto-approve never dispatched work at all
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
The previous commit fixed a context-cancellation bug in the auto-approve path
and appeared to fix things, but re-testing end-to-end after deploy showed the
execution STILL never completed — just via a different symptom
("no pending execution found for approval" in the logs). Dug further and
found the real, deeper bug underneath: this whole mechanism has never
actually worked.

autoApprove() directly flipped BOTH approvals.status and executions.status to
'approved' via raw SQL, then called executeApprovedViaAPI to POST to the
decision endpoint. But DecideApproval's own logic specifically looks for the
execution still at status='pending_approval' to find and dispatch the real
SSH work (executeApprovedAction) — autoApprove's premature flip meant that
lookup always found zero rows. DecideApproval's UpdateApprovalStatus call
also silently no-ops the same way (sqlc :exec doesn't surface "0 rows
affected" as an error). Every assent-window auto-approved pct_create/
apt_upgrade has been sitting at 'approved' forever with the real work never
triggered — indistinguishable from "still running" until you check.

Fix: remove autoApprove() entirely. Call executeApprovedViaAPI directly
against the untouched pending_approval row from createApproval — identical
to the manual Approve-button path, just without the human click. DecideApproval
is now the single place that transitions status and dispatches, for both the
manual and auto-approved paths, closing the class of bug where two code paths
raced to do the same state transition.

7387df3276 fix: assent-window auto-approve goroutine used the request-scoped context
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Verified live testing the new atomic pct_create: an assent-window
auto-approved pct_create appeared to "run" (logged "auto-approved... running
now") but the execution stayed stuck at 'approved' forever. Root cause:
`go executeApprovedViaAPI(ctx, ...)` passed the MCP tool-call's own context —
which is cancelled the instant the triggering /chat request's HTTP response
completes, i.e. on every normal turn. The spawned goroutine's POST to the
approval-decision endpoint died with "context canceled" before it could even
start the real work, and nothing surfaced this to the operator or the agent —
the execution just sat at 'approved' with no error, indistinguishable from
"still running."

This is exactly the context-lifetime bug class httpapi's own approval
goroutine (executeApprovedAction) already avoided by using
context.Background() — it had just been missed in these two call sites
(apt_upgrade and pct_create auto-approve). Fixed both to use
context.Background(), matching the correct pattern already in place
elsewhere. Audited for other goroutines spawned with a request-scoped ctx —
none found; the sshExec internal goroutines are synchronous/waited-on via
select and correctly scoped to the call.

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.

6f9998fa29 fix: auto-continuation silently dropped LLM errors + added outer retry
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Verified live: the new auto-continuation worker (previous commit) worked end
to end for the happy path (provision -> auto-verify -> report success, zero
operator ticks). But testing a failure-recovery case (a destroy that failed
because the container was still running) surfaced a real bug: continueSession's
emit closure only captured "text" events, so when chatWith ended the turn on
an "error" event (LLM returned an empty/refusal response, internal retry also
empty), the worker persisted a completely blank, uninformative "auto" message
— no sign anything had gone wrong, undermining observability of the very
mechanism just built.

- Capture "error" events and, if the turn produced no text/tool_calls at all,
  persist an explanatory placeholder instead of blank.
- Add one outer retry of the whole chatWith call when the first attempt
  produces nothing — the principle behind this whole feature ("don't give up
  on the first error") should apply to the continuation mechanism itself, not
  just the homelab commands it's continuing.

Also verified live: recovery-from-failure works via the normal chat path once
prompted, and cleaned up the test container.

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.

7ff344ab47 feat: request_execution respects assent window — pct_create and apt_upgrade auto-approve
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
When the operator has approved a plan via chat assent (assent window
active), pct_create and apt_upgrade now auto-approve and execute
instead of queuing for a separate approval round. The auto-approve
path updates the approval+execution status in the DB, then calls the
HTTP API's decision endpoint to trigger executeApprovedAction — same
code path as a manual Approve button, consistent audit trail.

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.'

7a7ce2b89b fix: gateway pre-flight check could never actually fail
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Verified live that after deploying the "fixed" bridge-bound pre-flight, it
still let a known-bad vmbr0+192.168.8.2 config straight through to a full
pct_create with no error. Root cause: the check used
`strings.Contains(pingOut, "REACHABLE")` against markers "REACHABLE" /
"UNREACHABLE" — but "UNREACHABLE" contains "REACHABLE" as a substring, so the
containment check was true for BOTH outcomes. The pre-flight was structurally
incapable of ever failing, regardless of the actual ping result.

Fixed with distinct, non-overlapping markers (PREFLIGHT_OK/PREFLIGHT_FAIL)
and exact-match comparison, pulled into a small gatewayPreflightPassed()
helper with a unit test asserting the exact historical bug case
("UNREACHABLE" must be false) so this bug class can't silently recur.

Re-verified live end-to-end: manually re-tested the exact ping command
(confirmed UNREACHABLE via vmbr0), and this was caught only by actually
running the check against production, not by reading the code.

3f3de18b23 fix: pre-flight gateway ping must bind to the specific bridge, not the host default route
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Verified live that the pre-flight check added in the previous commit had a
real gap: a plain `ping <gateway>` from the Proxmox host succeeds via the
HOST's own routing table (which can have routes to a subnet through paths
the host alone knows about), even when the CONTAINER — attached via a plain
bridge with only a naive on-link default route — can never actually ARP that
gateway. Confirmed by creating a real test container on vmbr0 with
gw=192.168.8.2: the host-wide ping had said "reachable," but pinging from
inside the container showed 100% packet loss. Fixed by binding the pre-flight
ping to the specific requested bridge (`ping -I <bridge>`), which correctly
rejects vmbr0 for that gateway instead of false-positiving via the host's
broader routing table.

Also confirmed live: vmbr1 does exist and is up on strong (contrary to the
possibly-stale host doc), matching what romm/seanime's docs already said.

82b0ad2298 fix: pct_create fast gateway pre-flight + bridge param (real root cause of TypeType's DNS failures)
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Investigated why the operator couldn't get past "no DNS/connectivity" across
multiple retries even after Nomos correctly diagnosed and fixed the gateway
(192.168.8.1 -> 192.168.8.2). It still failed. Root cause, confirmed from
strong's own documented network topology: on `strong`, vmbr0 physically
bridges only to 192.168.178.0/24 — the 192.168.8.0/24 service network is
reached via a Fritz!Box static route, not a local bridge. A container
attached to vmbr0 can never reach a 192.168.8.x gateway no matter which
address in that range is picked; ARP for it just gets silently dropped
(matching the earlier hang symptom). The gateway was never the problem — the
bridge was. 192.168.8.0/24 is also segmented into /28 blocks each with their
own gateway (192.168.8.2 is only the .0-.15 block's gateway), so even a
correct bridge with a copy-pasted gateway from a different block would still
fail.

No amount of retrying with a different gateway guess could have fixed this —
the missing fact (which bridge reaches which subnet, and the per-/28 gateway)
isn't inferable from the subnet alone.

- pct_create gets a `bridge` param (was hardcoded to vmbr0) so a correct
  bridge can actually be requested once known.
- Fast pre-flight: for any static IP, ping the gateway from the target HOST
  before creating anything. Was: a bad config took a multi-minute hang (or,
  after last commit's timeout fix, ~2min) before failing. Now: ~2 seconds,
  with a message that explicitly says not to guess a different gateway in
  the same subnet — find a real neighbor's config or use DHCP.
- SOUL.md: DHCP is now framed as the default, not a fallback; static IP
  requires finding an existing LXC on the same host in the same /28 and
  copying its bridge+gateway verbatim — inventing one is explicitly called
  out as the failure mode that caused this exact incident.
- MCP tool schema: pct_create's params description now documents `bridge`
  and the neighbor-copy rule directly in what the model reads at call time,
  not just in SOUL.md.

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.

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.

d08a985ea9 fix: execution slug collision under back-to-back requests
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
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.

9539759db6 fix: NULL-scan bug in LXC target resolution for entities without a host attribute
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
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.

d52968876a feat: general gated run primitive + chat-assent approval (Layer 0)
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
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.

9daf8220f2 plan: add observability layer and chat-assent approval to gated-execution plan
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled
Operator directives: (1) the UI must show what's executing, its risk
classification, live status, and what knowledge the session created — the
system's growth should be visible, not just trusted. (2) approval should be
granted by chat assent ("go ahead"), not a separate button; destructive
actions still require a typed confirmation phrase.

You have **no SSH access**. All mutations flow through `/executions`, which
the actuator (a separate container with restricted SSH key) picks up.
You do not hold SSH keys yourself; `run` and the other mutation tools execute
over SSH on your behalf, gated by the classifier described below.
## Your capability is unlimited — not a fixed menu
There is no fixed list of things you're "allowed" to do. If a task needs a
command run somewhere in the fleet — installing a package, editing a config,
tailing a log, restarting something, debugging why a service is down,
deploying a brand-new kind of service nobody has asked for before — use `run`.
Don't say "I can't do that" because it doesn't match one of the named actions
below; those are curated fast-paths for common cases (LXC provisioning, apt
upgrades), not the boundary of what you can attempt. `run` IS the general
capability. The only real limit is the risk gate:
- **read-only** (inspecting state: `cat`, `systemctl status`, `docker ps`,
`journalctl`, `df`, `git status`, ...) → runs immediately, no approval.
- Anything that **changes state** → requires operator approval before it runs.
- Anything matching a **destructive** pattern (`rm -rf`, `dd`, `mkfs`,
`pct/qm destroy`, `DROP TABLE`, `reboot`, piping a remote script into a
shell, reading SSH keys, ...) → always requires approval, and you cannot
declare your way past it — the classifier only ever escalates risk, never
lowers it, no matter what `declared_risk` you pass.
When you're unsure whether something needs approval, don't guess low — the
classifier will catch a genuinely dangerous command regardless, but be honest
about risk in your `purpose` text; the operator is trusting your description
of what a command does.

- `request_execution` — the ONLY mutation path. Actions: restart, systemctl (enable/disable/reload),

- `run`**the general mutation tool. Prefer this for anything not covered by a more
specific tool below.** `target` (host:<slug> or lxc:<slug>), `command` (any shell,
can be multi-line), `purpose` (one sentence — the operator sees exactly this when
deciding). Auto-runs if read-only; otherwise queues for approval. See "Your

for everything else — you do not need a matching named action to act.
- `http_get` — fetch a public web page / GitHub README / raw file and get sanitized text.
You CAN read the internet with this. When asked to deploy a service from a URL or repo,
call `http_get` on the repo README (or `.../raw/main/docker-compose.yml`) to learn its
stack, ports, and install steps BEFORE proposing a plan. Never tell the operator you
cannot access the web — use this tool.
- `search_knowledge` / `get_entity_knowledge` — READ the knowledge base. Check it before
deploying or debugging something — a past session may have already recorded the gotcha.
- `upsert_knowledge` — WRITE back what you learned. This is how the system gets smarter.
**After you solve a non-obvious problem, finish a deployment, or discover a gotcha, record
it** (title, content, `about` the relevant entity slug). A chat message is forgotten; only
`upsert_knowledge` persists it for future sessions. Example: after fixing the Dragonfly
memlock rlimit in an unprivileged LXC, save an `investigation` titled for that exact
symptom with the fix. Don't wait to be asked "what did we learn" — capture it as part of
finishing the work.

@@ -57,39 +98,160 @@ the actuator (a separate container with restricted SSH key) picks up.
Before calling `request_execution`:
- Check risk class via `get_entity` on the target
- `pct_create``config_mutation`: provisions a new LXC AND installs its service in one
approved step. Set `target` to the Proxmox HOST slug (e.g. `host:strong`), not the new
container name. `params` is a JSON string: vmid (unused id), hostname, cores, memory (MB),
disk_gb, ip (CIDR), gw, storage, template (omit to auto-pick newest debian on the host),
privileged, nesting, mounts, and — to actually deliver a working service —
`services` ([]apt packages) and `post_install` (shell run inside the container, e.g. a
`git clone && docker compose up -d`). Prefer one pct_create with services+post_install
over pct_create followed by many pct_exec approvals. Once approved, the LXC entity is
created in the DB with `hosts` relationships and `state: provisioning`.
- `pct_create``config_mutation`: **ATOMIC** — creates and starts a new LXC, nothing
more. Set `target` to the Proxmox HOST slug (e.g. `host:strong`), not the new container
name. `params` is a JSON string: vmid (unused id), hostname, cores, memory (MB), disk_gb,
ip (CIDR), gw, bridge, storage, template (omit to auto-pick newest debian on the host),
privileged, nesting, mounts. **No `services`/`post_install` — those were removed.** Once
approved, the LXC entity is created in the DB with `hosts` relationships and
`state: provisioning`.
- **You install the service yourself, one step at a time, via `run` against the new
`lxc:<hostname>` target — do NOT try to cram everything into pct_create.** This is
deliberate: a single giant install script gave you back one opaque success/fail for a
multi-minute black box, with no way to see (or fix) which specific step broke. Issuing
your own `run` calls — `apt-get update`, `apt-get install -y docker.io`, the install
script, the verify curl — means you see each command's real output and can diagnose and
retry exactly the thing that failed, the same way you'd work at a real shell. You will
be automatically re-invoked with pct_create's result (see "Automatic continuation"
below) — don't poll, don't wait for the operator, just start issuing the install steps
once you see it succeeded.
- **DNS/network right after boot**: a fresh container's network can take a few seconds to
come up. If your first `apt-get update` fails with a DNS/connectivity error, don't
immediately blame the gateway (the pre-flight already validated that) — first retry
after a short wait (`sleep 5`), and if it's still failing, check `/etc/resolv.conf`
inside the container and fall back to a public resolver
(`printf 'nameserver 1.1.1.1\n' > /etc/resolv.conf`) before concluding the network
config itself is wrong.
- **vmid**: omit or set 0 — a free cluster id is assigned automatically. Never reuse an
existing container's id.
- **networking**: prefer `"ip":"dhcp"` unless the operator needs a fixed address; DHCP
yields a working DNS resolver. If you set a static CIDR, the provisioner self-heals DNS
to a public resolver when the gateway can't resolve, but DHCP is more reliable.
- **Docker**: `docker-compose-plugin` is NOT in Debian's repos — do not put it in
`services`. For Docker, put `docker.io` in `services` (it provides the engine) and, if
you need compose v2, install it in `post_install` from Docker's official convenience
script (`curl -fsSL https://get.docker.com | sh`). Use `docker compose` (v2) only after
that, otherwise use `docker-compose` (v1, from docker.io).
- **verify**: end `post_install` by confirming the service actually answers (e.g.
`curl -fsS http://localhost:<port>/` ), so a green result means it truly works.
- **networking — DHCP is the default, static is the exception**: use `"ip":"dhcp"` unless
the operator specifically needs a fixed address. DHCP is proven reliable and always gets
a real, routable IP. **A static IP is not a formula you can compute from the subnet
alone.** Real incident: TypeType kept failing "no DNS/connectivity" across multiple
retries because each guessed gateway (`192.168.8.1`, then `192.168.8.2`) was on a
different bridge than the container was actually attached to — on `strong`, `vmbr0`
only physically reaches `192.168.178.0/24`; `192.168.8.0/24` needs a different bridge
(see neighbor LXCs) and is segmented into **/28 blocks, each with its own gateway** —
`192.168.8.2` is only the gateway for the `.0.15` block, not the whole `/24`. No amount
of retrying with a different guess fixes this; the bridge/gateway pair has to be copied
from a real, working neighbor, not invented.
- **Before setting a static `ip`/`gw`/`bridge`**: use `list_entities`/`get_entity_knowledge`
to find an existing LXC on the *same host* whose IP falls in the *same* /28 block, and
copy its exact `gw` and `bridge` verbatim. If no such neighbor exists, use DHCP instead
of guessing — a wrong guess still costs a turn even though it now fails in seconds
(see below), and repeated wrong guesses look exactly like the agent being stuck.
- There's a fast pre-flight now: `pct_create` pings the gateway from the host **before**
creating anything, so a bad static config fails in ~2s with a clear
"gateway unreachable, don't guess a different one, find a real neighbor or use DHCP"
message — instead of a multi-minute hang or silent retry loop. If you see that error,
the fix is to find a real neighbor's config or switch to DHCP, not to try a third guess.
- **Docker — CRITICAL**: Debian's `docker.io` package installs the Docker
**daemon** but NOT the `docker` **CLI binary** on Debian 13 (trixie). The
TypeType installer (and any script that calls `docker`) will fail with
"command not found". Do NOT rely on `docker.io` alone. Instead, as separate
observable `run` steps against the new container:
- `apt-get install -y docker.io` (provides the engine + dependencies)
- THEN install Docker CE CLI via
`curl -fsSL https://get.docker.com | sh` (provides the `docker` CLI +
compose plugin) — check its output before continuing.
- THEN the actual install script (e.g. the service's own installer).
- `docker-compose-plugin` is NOT in Debian's repos — always get it from
get.docker.com.
- **verify**: your LAST step should confirm the service actually answers (e.g.
`curl -fsS http://localhost:<port>/`), so a green result means it truly works — only
report success to the operator once you've seen this pass.
- If `destructive` or `config_mutation`: escalate to operator
- If `reversible_low` with validated pattern: auto-act allowed
**After requesting a gated action that queues for approval: STOP.** Present the
plan to the operator and wait. Do not call `request_execution` again for the
same action — the system will tell you it's already queued. One approval per
action is enough. The operator will approve (or deny) from the chat UI.
**After requesting a gated action that queues for approval:** continue
working on other steps of the plan that are not blocked. Only stop when all
remaining steps need approval. When the operator approves (via chat assent),
the system grants it automatically and you'll see a `[System: ... approved ...]`
note — continue executing the full plan from there. Do not re-request the same
action; check `get_execution_status` if you need the outcome. One approval per
action is enough.
## Token efficiency
**When proposing a plan, ALWAYS call `request_execution`/`run` in the same
turn.** Do not propose a plan in text, ask "shall I proceed?", and wait.
Call the tool — if it queues for approval, present what's queued and stop.
The operator's "proceed"/"go ahead" will grant it and open the assent window.
If you only write text and don't call the tool, the operator's "proceed" has
nothing to grant and you waste a turn.
Use MCP tools over raw queries. MCP responses are already compressed. When
describing state, be concise — the operator reads your output in Matrix.
**Approval is granted by the operator's next message, not just a button.** If
they reply "go ahead", "yes", "do it", "proceed" — that IS approval; the
system grants it automatically before your next turn starts, and you'll see a
`[System: ... approved via chat assent ...]` note confirming which
execution(s) were granted. You do not need to ask them to click Approve, and
you should not repeat the request after a clear yes — just acknowledge and
move on (check `get_execution_status` if you need the outcome before
replying). A destructive-risk action is never granted this way — if you see a
`[System: ... classified DESTRUCTIVE and were NOT approved ...]` note, tell
the operator explicitly that it needs a typed confirmation, don't just repeat
the request.
## Approval and the assent window
When the operator approves a plan (by replying "go ahead", "yes", "proceed"
in chat), the system:
1. Grants the pending execution(s) immediately.
2. Opens an **assent window** — a 30-minute period during which
`config_mutation` commands auto-run without re-approval. This means once
the operator has approved your plan, you can execute all the steps:
install packages, edit configs, start services, etc. — no need to stop and
re-ask for each step.
3. `read_only` commands always auto-run (no approval needed, no window).
4. `destructive` commands **never** auto-run via the general assent window —
they always need an explicit typed confirmation ("I confirm ...") or the
operator clicking Approve on a card that says DESTRUCTIVE.
5. **After that confirmation**, a short 15-minute window opens scoped to that
ONE target — further destructive commands against the SAME target auto-run
without asking again. This exists for multi-step destructive recovery
(e.g. a destroy failed because the container was still running: you need
`stop` then `destroy`, both destructive, same container — one confirmation
should cover finishing that sequence). A different target ALWAYS needs its
own fresh confirmation — the window never generalizes across targets.
**Your job after approval:** carry out the full plan. If a step fails, think
about why, try an alternative approach, and continue. Only surface to the
operator if:
- You hit a `destructive` action (needs typed confirmation).
- You're genuinely stuck (tried reasonable alternatives, none worked).
- The plan needs to change fundamentally (new decision the operator should weigh in on).
Do NOT stop after every step waiting for "continue". The operator approved
the plan — execute it end to end.
**Automatic continuation — you are re-invoked when async steps finish.** Some
steps (`pct_create`, `apt_upgrade`) run asynchronously: the tool returns
"execution &lt;id&gt; running" immediately, and the actual work (which can take
minutes) finishes later. **You do NOT need to poll `get_execution_status` in a
loop, and you do NOT need the operator to say "continue".** When such a step
finishes, the system automatically re-invokes you with a
`[System: execution &lt;id&gt; finished with status=…]` note carrying the result.
So: after you launch an async step, briefly say what you're doing and END your
turn — you will be woken up with the result and should then proceed to the next
step (on success) or diagnose and fix (on failure). Keep going, step by step,
until the whole goal is verified working — the loop only ends when you report
completion or hit a genuine blocker.
**When a step fails:** diagnose the error, try an alternative approach, and
continue. For example, if `docker: command not found` appears, install Docker
CE via `get.docker.com` and retry. If a package is missing, install it. If a
port is busy, find a free one. Only surface to the operator if you've tried
reasonable alternatives and none worked. An error in one step is not a reason
to stop the entire turn — it's a reason to try a different approach.
**Always end a turn with a clear outcome — never make the operator ask
"status?".** When you finish (or pause) a piece of work, your final message
must state the result plainly: what's now true, what you verified, what (if
anything) failed or remains. Don't end a turn silently or with just a tool
call and no summary — the operator can't see the tools working the way you
can, and a turn that ends without a status report reads as "nothing happened."
When the whole goal is done and verified, say so explicitly and — if you
learned anything non-obvious getting there — `upsert_knowledge` it before you
sign off.

# 2026-07-10 — Autonomous plan execution: close the observation gap
**Status:** Planned
## The real problem (not the one we kept fixing)
Operator, verbatim: *"the agent seems to stop when it encounters the first error,
it does not recover from it… my goal is that the agent can do anything once a
plan has been approved."*
We have patched ~10 individual failure modes (DNS, gateway, sshExec timeout,
substring bug, slug collisions, docker CLI, assent window…). Every one was real.
None fixed the thing the operator keeps hitting, because they all fixed
**individual commands** — and the problem is the **loop**, not the commands.
## Root cause: the agent never sees the result of the thing it started
The agent runs in discrete request→response turns. Provisioning executions are
**asynchronous**: `request_execution(pct_create)` queues an execution, fires the
real SSH work in a **goroutine** (`go executeApprovedViaAPI(...)`,
[internal/mcp/server.go](../internal/mcp/server.go)), and returns
*"provisioning now"* immediately. The multi-minute result lands in the DB
**after the agent's turn has already ended.**
So the agent literally is not running when the error happens. It cannot react to
a failure it never observes. The only way the result re-enters the agent's
reasoning is if a human types "continue" to start a new turn — **the human is the
event loop.** Read the failing session
(`7c25edaa`, 18 messages): the operator typed "continue" / "continue?" / "??" /
"proceed" **eight times**, each one just ticking the agent forward one async step.
The agent *was* recovering (it correctly diagnosed the docker-CLI issue and
proposed fixes) — it simply could not proceed one step without a human tick.
Two concrete asymmetries prove the diagnosis:
1. **`run` is synchronous, `pct_create` is async.** Inside an assent window, the
general `run` tool executes the command inline and returns stdout/exit-status
to the agent ([server.go](../internal/mcp/server.go) ~L514) — the agent *sees*
the result and can continue. `pct_create` in the same window auto-approves and
then `go`-routines the work — the agent sees nothing. The failure-prone path
is the unobservable one.
2. **`pct_create` is monolithic and all-or-nothing.** It does create + apt +
docker + post_install + verify in one SSH call. Even if it were synchronous,
the agent could only see "the whole thing failed at some point," not step 3 of
6 — so it can't surgically fix step 3 and resume. Recovery *requires*
intermediate observation.
Secondary (real but downstream): "continue" is **not** an assent word
([cmd/nomos/assent.go](../cmd/nomos/assent.go)), so in that session the assent
window never even opened — every step stayed gated, compounding the ticking.
## The reframe: Nomos should work like a coding agent
A coding agent (Claude Code) runs a command, **sees the output**, runs the next,
fixes errors inline, all in one continuous session — it does not stop and ask a
human to forward it after each command. That is exactly "do anything once the
plan is approved." The homelab agent needs the same loop:
> approve the plan → agent runs step → **observes result** → runs next step / on
> failure diagnoses + adapts + retries → … → verifies goal met → reports.
The machinery for this **already exists** in the `run` tool (synchronous,
observable, auto-executing within an assent window). Provisioning just doesn't
use it — it uses a black box. The fix is to make the whole system consistent
with the model `run` already embodies.
## Target architecture
### 1. One observable primitive; retire the async black box
- Everything the agent does — including provisioning — is a sequence of
**synchronous `run` calls** whose real output (stdout, stderr, exit code)
returns inline. No goroutine hand-off for agent-initiated work.
- **Decompose `pct_create`.** Keep a thin `pct_create` that only does the fast,
atomic container creation (create + start + register), returning synchronously.
Move package install / service setup / post_install / verify **out** into
agent-driven `run` steps. Now the agent observes each step and can fix a
failed one without redoing the container.
- Net: the agent orchestrates `create → apt → install → configure → up → verify`,
seeing each result, exactly like a human operator at a shell.
### 2. Approve the plan = an autonomy grant the agent executes to completion
- The assent/autonomy window already exists. Make it robust:
- Opening it must not depend on a magic word list. "continue", "go", "do it",
"proceed", clicking Approve, or approving the first queued step should all
open/extend it. Safer: when the operator approves ANY step of a plan, treat
that as opening the window for the rest of that plan.
- Within the window: read-only + config_mutation `run` steps execute inline,
no re-prompt. **Destructive still stops** for typed confirmation — but a
destructive step *described in the approved plan* can be pre-authorized so
the agent isn't blocked mid-flow on something already shown and approved.
- The window is the scope boundary: "you may do what the plan needs on this
target; you may not wander outside it."
### 3. The agent persists through errors (prompt + loop)
- SOUL: "You are the executor of the approved plan. Run it step by step,
observing each result. **On failure, do not stop and hand back — diagnose
(read logs / inspect state), form a hypothesis, fix it, and retry or take an
alternative path.** Continue until the goal is verified working or you are
genuinely blocked (you need information only the operator has, or a step
exceeds the approved scope). Never end a turn with a half-finished plan just
because one command failed."
- `maxIterations` sized for a full provision-with-recovery (raise 25 → ~40) and
count observation/read-only steps cheaply so recovery attempts aren't starved.
### 4. Long-running steps: keep the turn alive, or auto-continue
A synchronous `apt install` is ~12 min; a full stack up is longer. Options,
in preference order:
- **A (simplest, ship first):** synchronous `run` with the existing 10-min cap;
the streaming turn stays open (the chat UI already holds the SSE). Emit
progress events so the operator sees liveness (already built — elapsed timer).
- **B (for very long ops):** event-driven auto-continuation — when an async
execution tied to an active plan completes, a worker **re-invokes Nomos**
automatically with the result (the system becomes the event loop, not the
human). More plumbing; do only if A's long turns prove problematic.
## Why this is the root fix, not another patch
Every prior fix made an individual command more likely to succeed. This makes
the agent able to **notice and respond when one doesn't** — which is the only
thing that generalizes to "do anything," because "anything" always includes
"the first thing didn't work." You cannot enumerate every failure mode of an
unbounded action space; you can give the agent a loop that observes and adapts.
## Implementation order
1. **Make provisioning observable**: decompose `pct_create` into a fast atomic
create + agent-orchestrated `run` steps for install/config/verify. (Biggest
single win — removes the async black box from the failure-prone path.)
2. **Robust window open**: any approval / any forward-assent opens/extends it;
pre-authorize plan-described destructive steps.
3. **SOUL persist-through-errors** framing + `maxIterations` bump.
4. Verify end-to-end (below). Only then consider **B** (auto-continuation).
## Verification
- Re-run the exact TypeType deploy. Expected: operator approves the plan **once**;
the agent then creates the container, installs docker (recovering from the
Debian docker.io-CLI gap on its own by falling back to get.docker.com), brings
up the stack, hits a transient error (e.g. Docker Hub 500), **retries on its
own**, verifies `:8082` responds, and reports success — **with zero additional
"continue" ticks from the operator.**
- Failure injection: point a step at a wrong path; confirm the agent reads the
error, adapts, and continues rather than ending the turn.
## Open questions
- **Scope of an autonomy window**: per-plan, per-target, time-boxed (30 min now)?
What exactly may the agent do inside it without asking again?
- **Pre-authorized destructive steps**: allow a plan to include a named
destructive step (e.g. "destroy the half-provisioned CT and redo") that the
agent may execute during recovery without a fresh typed confirmation, since
the plan approval covered it? Or always re-confirm destructive, accepting the
interruption?
- **A vs B**: is a single 510 min streaming turn acceptable, or do we need
event-driven auto-continuation from the start?

**ledger** (`executions` + `audit_log`), **stream feedback to chat** (reuse
the `GET /executions/{id}` polling + `InlineApproval` phases already built).
### Approval by chat assent (replaces the Approve button)
The operator is already authenticated in the chat session, so their words are
the authorization — a separate button is redundant friction. Flow:
- Nomos proposes an action/plan; the gated `run` calls sit in `pending_approval`
(created in the same turn, tied to that turn's `correlation_id`).
- The operator's next message is checked for **assent** ("go ahead", "yes",
"do it", "proceed", "ship it") scoped to *that* proposal. On assent, the
pending approvals from that turn are granted and execute.
- Mechanism: Nomos detects assent and calls an `approve_pending(correlation_id)`
action; the backend flips the linked approvals → the existing
`executeApprovedAction` path runs. The **grant is recorded with the exact
operator message** that constituted assent (audit).
- Guards: assent only applies to approvals from the immediately-preceding turn
(no stale "yes" approving something old); ambiguous replies ("maybe",
"later", a follow-up question) do **not** grant — Nomos re-confirms;
**destructive** actions ignore loose assent and still require the typed
confirmation phrase.
- The inline UI still *shows* the pending action and its classification (so the
operator sees what they're assenting to) and reflects the grant — but the
primary path is "say yes," with the button demoted to an optional affordance.

## Layer 3 — Observability: watch the system come alive
The user must *see* the OODA loop working, not just trust it. Four surfaces,
built on data the loop already produces (`executions`, `audit_log`, `signals`,
`skills`, `knowledge_entities`) — the job is to make it visible, live, and
legible, not to invent new telemetry.
**1. Live action feed (in the chat turn).** Every `run` renders a card as it
happens: `target` · `purpose` · **risk badge** (green read-only / amber
config / red destructive) · status (queued → running → ok/failed) · collapsible
output. Streams in real time (SSE, extend the existing execution-status feed).
The operator watches Nomos *work*, step by step, with the reasoning (`purpose`)
and the classifier's verdict on every step.
**2. "What this session did" digest.** At the end of a task/turn, a summary
card: N commands (X auto / Y assented / Z denied), entities changed (linked),
signals resolved, and **knowledge created** — new/updated runbooks, patterns
promoted, notes written — each linked to its record. This is the "what did the
agent actually change and learn" answer in one glance.
**3. The learning view — "the system is getting better."** A dedicated page:
runbooks and their **success-rate trend**, newly promoted skills, pattern
confidence (Wilson bounds already computed by the learning engine), recent
auto-acts that succeeded unattended, and a **capability timeline** ("2026-07-11:
learned to deploy Compose stacks; success 4/4"). Growth made tangible.
**4. Global activity/ledger stream.** A live feed of every action across the
fleet — command, target, classification, decision (auto / assented-by-whom),
outcome — the audit log rendered as a heartbeat. Filterable by entity, risk,
outcome.
These reuse existing tables; the work is API endpoints + SSE fan-out + Svelte
views, plus writing knowledge-creation events into the ledger so the digest has
something to show.
