feat: Learning page — capability timeline + trend, built on real data

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.

+risk_class: reversible_low
+inputs: [session_id]
+---
+# Session review
+
+Analyze Nomos chat sessions from the live database, diff objectives
+against outcomes, and propose fixes.
+
+## 1. Retrieve session data
+
+```bash
+# List recent sessions
+curl -s http://localhost:8092/sessions | jq '.sessions[:5]'
+
+# Fetch one session with messages
+curl -s http://localhost:8092/sessions/{session_id} | jq .
+```
+
+## 2. Classify the session
+
+For each session determine:
+
+| Dimension | Check |
+|-----------|-------|
+| Objective | What was the user trying to accomplish? |
+| Outcome | Was it achieved? (read final assistant text) |
+| Tool calls | Count, unique tools, redundancy (e.g., N+1 fan-out) |
+| Blockers | Missing action? Missing tool? Model refusal? Empty response? |
+| User frustration | Did the user need to clarify/correct/repeat? |
+| Message sizes | Content blob sizes — truncation needed? |
+
+## 3. Key failure signatures
+
+| Signature | Root cause | Fix |
+|-----------|-----------|-----|
+| Agent: "I can't run X — only supports Y" | Missing action in `request_execution` | Add action in `internal/mcp/server.go` |
+| Agent: "No local knowledge on that" + no web tool | Missing `http_get` / web fetch MCP tool | Add MCP tool |
+| Empty assistant bubble (text="", no tools) | Model returned blank completion | Retry + error surfacing |
+| Non-English boilerplate refusal | Flash-tier model degradation | Response quality guard |
+| >30 tool calls per turn, same tool repeated | N+1 fan-out instead of bulk tool | Enrich bulk tools + tighten SOUL.md |
+| Message >50KB in DB | Raw tool results persisted verbatim | Truncation in `store.go` |
+
+## 4. Extract patterns across sessions
+
+```bash
+# All sessions summary
+curl -s http://localhost:8092/sessions | jq -r '.sessions[] | "\(.id[:8]) \(.title[:80]) \(.created_at[:16])"'
+
+# Message count + tool count per session
+for id in $(curl -s http://localhost:8092/sessions | jq -r '.sessions[].id'); do
+  msgs=$(curl -s "http://localhost:8092/sessions/$id" | jq '.messages | length')
+  tools=$(curl -s "http://localhost:8092/sessions/$id" | jq '[.messages[].content.tool_calls | length] | add')
+  echo "$id $msgs msgs $tools tools"
+done
+```
+
+## 5. Output format
+
+```
+Session: {id[:8]} — "{title[:60]}"
+  Messages: {N} ({user}/{assistant})
+  Tool calls: {total} across {turns} turns
+  Top tools: {name:count, name:count, ...}
+  Objective: {one-line summary}
+  Outcome: ✅ / ❌ / ⚠️
+  Blockers: {list or "none"}
+  Fixes needed: {concrete actions}
+  Severity: blocker | friction | cosmetic

-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.
 
 ## Key MCP tools
 
-- `get_entity`, `list_entities` — resolve slugs to state
+- `list_lxcs` — all LXC containers with host, IP, health (use for fleet-wide questions)
+- `get_lxc_state` — per-container `pct status` (use only for a specific named container)
+- `get_state_snapshot` — fleet health, disk, drift at a glance
+- `get_health_summary` — fleet health counts
+- `query_metrics` — time-series metrics (prefer over per-entity `get_trend` for fleet-wide)
+- `list_entities` — resolve slugs to state (pass `type` filter when possible)
+- `get_entity` — single-entity detail
 - `get_blast_radius` — understand impact before requesting action
-- `get_health_summary` — fleet status at a glance
 - `get_signal_history` — open alerts
-- `get_trend` — metric trends for decisions
-- `request_execution` — the ONLY mutation path
+- `get_trend` — metric trends for a specific entity (single-entity only)
+- `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
+  capability is unlimited" above.
+- `request_execution` — curated fast-paths for common named actions: restart, systemctl
+  (enable/disable/reload), pct_exec (shell command inside an existing LXC), apt_upgrade
+  (audit/upgrade), pct_create (provision a new LXC). Use these when they fit; use `run`
+  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.
 - `get_agent_activity` — your own behavior log
 
+### Tool selection rules
+
+- **Fleet-wide questions** (e.g. "which hosts are saturated?", "what needs updating?"):
+  prefer bulk tools: `list_lxcs`, `get_health_summary`, `get_state_snapshot`,
+  `query_metrics`. Only fall back to per-entity tools (`get_lxc_state`, `tail_log`,
+  `get_trend`) for a specific named entity the user asked about.
+- **One call > many calls**: each `get_lxc_state` is a live SSH round-trip.
+  `list_lxcs` answers the same question in one call. Use it.
+- When a bulk tool's summary isn't enough for a specific entity, call the
+  per-entity tool for that one entity — not for every entity in the fleet.
+
 ## Policy awareness
 
 Before calling `request_execution`:
 - Check risk class via `get_entity` on the target
+- `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 — 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
 
-## Token efficiency
+**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.
 
-Use MCP tools over raw queries. MCP responses are already compressed. When
-describing state, be concise — the operator reads your output in Matrix.
+**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.
+
+**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.

+# 2026-07-09 — Session execution, UX, and learning improvements
+
+**Status:** Planned
+
+## Goal
+
+Fix the hard blocker and UX issues found in the latest production Nomos session
+(`b9c5de7c-e0b5-424c-9149-9fd45b2e7011` — "deploy TypeType as an LXC on strong").
+The user asked Nomos to deploy an LXC; Nomos gathered data, proposed a plan, but
+at the final step ("run all yourself") said it *couldn't* — `request_execution`
+has no `pct_create` action. The user's objective was not achieved.
+
+## Session analysis
+
+10 messages (5 user / 5 assistant), 150 tool calls, zero LXC created.
+
+| Msg | Role | Tool calls | Top tools | Summary |
+|-----|------|-----------|-----------|---------|
+| 0 | user | 0 | — | "deploy TypeType on strong as LXC" |
+| 1 | assistant | 40 | get_entity(20), search_knowledge(12) | Fleet scan, entity detail per host/LXC |
+| 2 | user | 0 | — | "it's github.com/Priveetee/TypeType, use tube.hubris.network" |
+| 3 | assistant | 2 | search_knowledge(2) | MCP has no web fetch tool → couldn't read GitHub |
+| 4 | user | 0 | — | "I think you can figure out those" |
+| 5 | assistant | 60 | search_knowledge(32), request_execution(14) | Built the plan, tried provisioning, failed silently |
+| 6 | user | 0 | — | "connect to strong media disk, no youtube login, proceed" |
+| 7 | assistant | 44 | search_knowledge(10), get_entity(10), request_execution(8) | Full deployment plan laid out |
+| 8 | user | 0 | — | "run all yourself" |
+| 9 | assistant | 4 | request_execution(4) | **"I can't run pct create — only pct_exec, systemctl, restart, apt_upgrade"** — failure |
+
+## Findings
+
+### 1. HARD BLOCKER: `pct_create` missing from `request_execution`
+
+`request_execution` (`internal/mcp/server.go:264-376`) supports `restart`,
+`systemctl`, `pct_exec`, `apt_upgrade`. The actuator has `ProvisionLXC()`
+(`internal/actuator/actuator.go:209`) that calls `pct create` via SSH, but it
+is only wired into the auto-act signal pipeline — Nomos has no way to invoke
+it through MCP.
+
+Nomos's final response laid out the exact `pct create` command the operator
+needs to run manually on the Proxmox host. That's a dead end for the user, who
+expected the agent to execute from chat.
+
+**Fix:**
+- Add `pct_create` action to `request_execution` handler.
+- Wire it to the existing `ProvisionLXC()` function.
+- Classification: `config_mutation` — requires operator approval. Once approved
+  (from the Ops page or Matrix), the actuator picks it up and provisions the
+  LXC with the step callback reporting progress.
+- Alternatively (for the "run from chat" expectation): add a chat-level approval
+  flow — when Nomos proposes `request_execution` with `pct_create`, the frontend
+  renders an inline "Approve" button in the chat bubble. Operator clicks → it runs.
+  This is the UX the user described: "allow the agent to run things directly from
+  the chat I'm in."
+
+### 2. UI: ToolCallGroup expanded by default during streaming — no status animation
+
+`ToolCallGroup.svelte` uses `<details open>` when `active=true`. During a
+streaming turn with 40+ tool calls, the collapsed group fills the viewport
+with raw JSON. The summary header shows only a static icon and "N tools" text.
+
+**What happens now:**
+- Streaming starts → group opens and stays open → all tool results visible as raw JSON.
+- When streaming ends → auto-collapses. No animation.
+- Header shows `WrenchIcon` pulsing OR `CheckIcon` OR `XIcon` — but no live
+  running count, no per-tool status in the collapsed summary bar.
+
+**What should happen:**
+- Group starts **collapsed** by default. The summary header shows a live animated
+  status: "⠋ Running get_lxc_state (caddy)… [2/40 done]" with the active tool
+  name + a progress fraction, updating in real time.
+- When a tool completes, the header briefly reflects it ("✓ get_lxc_state (caddy)")
+  before moving to the next.
+- Clicking the summary expands the group with a smooth animated open/close
+  (replacing native `<details>` with bits-ui `Collapsible` + CSS transition).
+- On load from history (not streaming), always starts collapsed.
+
+**Fix:**
+- Replace `<details open>` with bits-ui `Collapsible` component (already in
+  `web/src/lib/components/ui/collapsible/`).
+- Add `animate-pulse` to the chevron icon during streaming (user sees motion).
+- Add a `statusText` derived that shows the in-progress tool name + count.
+- CSS animation: `Collapsible.Content` supports `forceMount` with transitions.
+
+### 3. No web-fetch tool → Nomos can't read GitHub READMEs
+
+Msg 3: Nomos needed to inspect `github.com/Priveetee/TypeType` to understand the
+stack. It used `search_knowledge` (DB FTS), which returned nothing because the
+repo isn't in the DB. The agent had no way to fetch external URLs.
+
+The MCP has 27 tools (21 listed in AGENTS.md + 6 more added since), but none
+for HTTP/web fetching. Nomos can only query the DB or execute SSH commands on
+existing hosts.
+
+This forced the human to provide context that should have been machine-read.
+
+**Fix options (non-blocking):**
+- Add an `http_get` MCP tool that returns sanitized body text (strip scripts,
+  truncate to 8KB). Rate-limited per-turn.
+- Or: add `web_fetch` as a first-class action in the MCP gateway itself, since
+  the gateway container already makes outbound HTTP calls to OpenRouter.
+
+### 4. Task: Bulk-tool awareness already in SOUL.md but not enough
+
+The SOUL.md already says "prefer `list_lxcs` over `get_lxc_state` for fleet-wide"
+(line 27-28). But msg 1 still made 40 calls. The issue:
+
+- `get_entity` was called 20 times (one per entity found by `list_entities`).
+  `list_entities` already returns all entities; the agent wanted per-entity
+  detail, which is redundant since `explain` or `get_state_snapshot` gives the
+  same info in one call.
+
+**Fix (already planned in `2026-07-09-chat-sessions-improvements.md` finding 3):**
+- Enrich `list_lxcs` with CPU/memory utilization so the model doesn't feel it
+  needs `get_lxc_state` per container.
+- Add `get_tools_summary` to SOUL.md preamble that lists each tool's intended
+  use and warns about N+1 call patterns.
+
+### 5. Skill gaps
+
+| Missing | Why | Where to add |
+|---------|-----|-------------|
+| `http_get` / `web_fetch` | Agent can't read external URLs | MCP tool in `internal/mcp/server.go` |
+| `session-review` skill | No way to learn from failed sessions | `.agents/skills/session-review/SKILL.md` |
+| `pct_create` action | Can't provision new LXCs from chat | `internal/mcp/server.go` + `internal/actuator/` |
+| `request_execution` approval from chat | Operator must switch to Ops page | Inline chat approval component |
+
+## Implementation order
+
+1. **Add `pct_create` to `request_execution`** (`internal/mcp/server.go`) —
+   hard blocker, needed for the session's objective.
+2. **ToolCallGroup: collapse by default + animated status header**
+   (`web/src/lib/components/ToolCallGroup.svelte`) — immediate UX win, the user
+   explicitly asked for this.
+3. **Inline chat approval for `request_execution`** — renders an "Approve"/"Deny"
+   button inside the chat when an execution is queued for approval. Lets the
+   operator approve from the same chat.
+4. **`session-review` local skill** — lives in `.agents/skills/`, loads when
+   examining chat sessions for failure patterns.
+5. **`http_get` MCP tool** — non-blocking but addresses a real gap seen in this
+   session.
+
+## Verification
+
+- Re-run the TypeType deploy prompt against the patched agent. Confirm:
+  - Agent proposes plan as before (keep plan-proposal behavior).
+  - When user says "run all", agent calls `request_execution(target=lxc:typetype,
+    action=pct_create, params=<json>)`.
+  - Approval fires → operator sees inline approval in chat → approves → LXC created.
+- ToolCallGroup: start a session that triggers 5+ tool calls. Confirm:
+  - Group starts collapsed.
+  - Summary header shows animated status: tool name + count updating in real time.
+  - Clicking expands smoothly.
+  - On session reload (history), stays collapsed.
+- Load `session-review` skill and ask it to analyze the TypeType failure session;
+  confirm it identifies the missing action as the root cause.

+# 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 ~1–2 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 5–10 min streaming turn acceptable, or do we need
+  event-driven auto-continuation from the start?

+# 2026-07-10 — General gated execution: from fixed actions to unlimited-but-gated
+
+**Status:** Planned
+
+## Goal
+
+Make Nomos able to do **anything** needed to maintain the homelab — provision
+LXCs, deploy services, debug, restart, fix configs, investigate — without that
+capability being a fixed enum of hand-coded actions. The action space is
+unlimited; the *gate* on it is a risk classifier + operator approval, not a
+whitelist of tricks. Knowledge (the graph + runbooks) supplies the *how*; the
+agent's reasoning supplies the *what*; the classifier supplies the *may I*.
+
+Operator directive (2026-07-10): **"The number of actions the agent should be
+able to do is unlimited. We need logic to gate destructive actions, but we
+should not limit what the agent can do."**
+
+Chosen autonomy posture for v1: **approve-most (cautious)** — only genuinely
+read-only commands auto-run; anything that changes state requires operator
+approval. We can relax later once the classifier and ledger have earned trust.
+
+Operator directive #2 (2026-07-10): **"I want to see the system come alive and
+learn and get better."** Observability is a first-class deliverable, not a
+side-effect. As a user I must be able to see, in real time: what is being
+executed, on what, and why; how it was classified and routed; what the outcome
+was; and — crucially — **what knowledge the session created** (new runbooks,
+patterns, resolved signals, ledger entries) so the system's growth is visible.
+
+Operator directive #3 (2026-07-10): **approval is granted by chat assent, not a
+button.** When Nomos proposes a plan/action and the operator replies "go ahead"
+/ "yes" / "do it" in the chat, that assent *is* the approval. No separate
+Approve button for the normal case. (Destructive actions still require an
+explicit typed confirmation phrase — see Safety.)
+
+## This is a realignment, not a new idea
+
+[.agents/OIKOS.md](../.agents/OIKOS.md) already specifies this exact model:
+
+> The classifier scores **risk class × blast radius × confidence** and routes:
+> auto-act / escalate / queue. The classifier can only *lower* autonomy relative
+> to policy, never raise it. When in doubt, escalate.
+> Act — execute through `homelab` commands or **runbooks** (never ad-hoc SSH).
+
+So the target architecture is the *documented* architecture. The problem is the
+implementation diverged from it on the agent's action path.
+
+## Gap analysis (grounded in code)
+
+| Designed (OIKOS.md) | Actually implemented today |
+|---|---|
+| Classifier routes every action by risk × blast × confidence | [`internal/policy/classify.go`](../internal/policy/classify.go) `ClassifySignal()` only classifies **Signals** (the Observe pipeline), by entity+action-type. It is **not** called by the agent's mutation path. |
+| Agent acts through unlimited **runbooks** | Agent acts through `request_execution` with a **hard-coded enum**: `restart, systemctl, pct_exec, apt_upgrade, pct_create` ([`internal/mcp/server.go`](../internal/mcp/server.go)), each bespoke Go, gated by per-action `if`s, not the classifier. New capability = new Go + redeploy. |
+| Runbooks/skills are executable data | `skills` table + `.agents/skills/*` + `knowledge_entities` exist and are *readable* (`get_skills`), but **nothing executes a runbook**. The knowledge is inert w.r.t. action. |
+| Auto-act loop consumes classified signals and acts | [`internal/actuator/actuator.go:124`](../internal/actuator/actuator.go) is a literal `"stub execution"` — it marks work done without doing it. |
+| "Never ad-hoc SSH" | `pct_exec` **is** ad-hoc SSH (arbitrary shell in a container) and **auto-runs with no approval or classification**. |
+
+Net: the elegant model exists as scaffolding (classifier, policy schema, risk
+classes, blast-radius graph walks, skills-as-data, ledger, and the
+approval+feedback plumbing hardened in the 2026-07-09/10 sessions), but the live
+agent→action path is a bag of tricks that bypasses all of it. Everything added
+in the recent LXC-deploy work (`pct_create` + DNS/VMID/template logic) made the
+bag *bigger* — reliable, but on the wrong axis.
+
+**Bones that already exist and get reused:** `internal/policy` (classifier +
+`computeBlastRadius`/`blast_radius()` SQL), `risk_classes`/`action_risk` tables,
+`seeds/policy.yaml`, `executions`/`approvals`/`audit_log`, the MCP SSH machinery,
+and the inline approval + execution-status feedback loop (chat polls
+`GET /executions/{id}`).
+
+## Target architecture — three layers
+
+### Layer 0 — one general gated primitive (the foundation)
+
+Collapse the fixed enum into essentially one tool:
+
+```
+run(target, command, purpose, [declared_risk])
+```
+
+- `target` — any host or LXC slug; resolves to SSH (host) or `pct exec` (LXC).
+- `command` — arbitrary shell.
+- `purpose` — the agent's stated intent (shown to the operator, feeds classify).
+- `declared_risk` — optional agent self-assessment.
+
+Every call flows through:
+
+1. **Classify** the command → `read_only | reversible_low | config_mutation |
+   destructive`. Rule-based:
+   - read-only **allowlist** (e.g. leading verb in `cat, ls, stat, journalctl,
+     systemctl status|is-active, pct config|status, df, free, uptime, ip, ss,
+     docker ps|logs, git status|log`) → `read_only`;
+   - destructive **denylist** (`rm -rf`, `dd`, `mkfs`, `wipefs`, `pct destroy`,
+     `qm destroy`, `shutdown`, `reboot`, `> /dev/`, `:(){ :|:& };:`, secret
+     exfiltration, piping remote scripts to a root shell) → `destructive`;
+   - anything writing state / installing / editing configs → `config_mutation`;
+   - **default → escalate** (`config_mutation`) when unsure.
+   The classifier may only make `declared_risk` **stricter**, never looser
+   (mirrors "can only lower autonomy, never raise").
+2. **Route** (approve-most posture):
+   - `read_only` → auto-run + ledger, no approval.
+   - `reversible_low` / `config_mutation` → **operator approval via chat assent**
+     (v1 gates all state changes; a later posture can auto-run `reversible_low`).
+   - `destructive` → approval **+ typed confirmation phrase**.
+3. **Execute** (existing SSH/`pct exec`), **verify** (optional check command),
+   **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 0 alone delivers "the agent can attempt anything; state changes are gated."
+
+### Layer 1 — runbooks as executable data (reliability without rigidity)
+
+The hard-won procedures become **runbooks in the knowledge DB**, retrieved and
+executed step-by-step via Layer 0 — not frozen Go:
+
+- `pct_create` + its DNS-self-heal / VMID-collision / template-resolution /
+  locale logic becomes the canonical **"provision LXC" runbook** (parametric
+  steps the agent fills in and runs through `run`). The reliability survives as
+  documented, reusable steps rather than a compiled handler.
+- New capability = **new runbook (data)**, no redeploy.
+- Keep a *small* set of mechanical helpers where a shell step is genuinely
+  fiddly (e.g. "pick a free cluster VMID"), exposed as callable sub-tools — but
+  the flow is agent-driven, not enum-driven.
+
+This is the crucial **both/and**: the general primitive is the unlimited escape
+hatch; curated runbooks are the reliable fast-path so the agent doesn't
+re-derive DNS/VMID/docker every time (the exact thing that failed repeatedly in
+the 2026-07-09 sessions).
+
+### Layer 2 — learning closes the loop
+
+Successful ad-hoc `run` sequences get promoted into runbooks/patterns (the
+`learning` engine + `skills` table already exist for this); the failure ledger
+informs retries. The system grows more capable **as data**, not as code.
+
+## 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.
+
+## Safety model (the whole point of the gate)
+
+- **Default-escalate.** Nothing is *forbidden*; risky things need the operator's
+  "yes." Unknown/unparseable risk → approval.
+- **Hard denylist** for catastrophic patterns → always typed confirmation, even
+  if the agent declared them safe.
+- **Blast radius at approval time** — graph walk (`blast_radius()` exists):
+  "this restarts caddy → 8 downstream services."
+- **Preview / dry-run** where the command supports it.
+- **Kill-switch** (`global.auto_act`, per-target `never_auto_act.*`) already
+  exists; extend to a global "require approval for everything" flip.
+- **Full audit ledger** — every command, its classification, decision, actor,
+  output. Non-negotiable.
+- **Scope guards** — resolve `target` to a real entity first; refuse commands
+  against `destroyed`/unknown targets; cap output size (already done).
+
+## Honest risks / tradeoffs
+
+- Trades a small vetted surface (5 actions) for arbitrary root across the fleet,
+  LLM-driven, gated only by classifier + approval. Classifying arbitrary shell
+  perfectly is impossible; **default-escalate + hard denylist + always-on audit**
+  is the mitigation, not perfect classification.
+- Approve-most means more operator clicks initially. Acceptable while trust is
+  built; the posture is a config knob, not a rewrite.
+- Runbook-as-data can drift from reality like any doc; the ledger + verify step
+  + learning loop are the correction mechanism.
+
+## Migration path (incremental, each step shippable)
+
+1. **Command classifier** — extend `internal/policy` with
+   `ClassifyCommand(cmd, declaredRisk) → riskClass` (allowlist/denylist/default-
+   escalate + can-only-escalate rule). Unit-tested against a corpus of safe /
+   mutating / catastrophic commands.
+2. **`run` tool** — new MCP tool routing classify → gate → execute → the
+   existing feedback path. Ship alongside the current tools (no removal yet).
+3. **Live action feed (UI)** — render each `run` as a streaming card in chat:
+   purpose, target, risk badge, status, output. This is the first "come alive"
+   win and validates the SSE fan-out.
+4. **Chat-assent approval** — assent detection scoped to the last turn's
+   `correlation_id` → `approve_pending`; grant records the operator's message;
+   destructive still needs the typed phrase. Demote the Approve button.
+5. **Approval context** — surface risk class + blast radius + purpose inline so
+   the operator sees what they're assenting to.
+6. **Session digest + activity stream (UI)** — "what this session did / created"
+   card and the global ledger feed; write knowledge-creation events to the
+   ledger so there's something to show.
+7. **Runbook execution** — a "provision LXC" runbook (ports the current
+   `pct_create` logic) executed via `run`; validate parity with today's handler.
+8. **Learning view (UI)** — runbook success-rate trends, promoted skills,
+   capability timeline.
+9. **Retire the enum** — convert remaining hard-coded actions to runbooks; make
+   `request_execution` a thin deprecated alias or remove it.
+10. **Revive auto-act** — replace the actuator stub, reusing the *same*
+    classifier for the Observe→Act direction (signals), still approve-most.
+
+## Verification
+
+- Classifier corpus test: read-only commands auto-pass; a set of known
+  catastrophic commands always route to destructive+confirmation; ambiguous
+  commands escalate. No command auto-runs that mutates state.
+- End-to-end: operator asks Nomos a novel task **not** in the old enum (e.g.
+  "tail caddy's error log and restart it if it's flapping"); Nomos composes
+  `run` calls; read-only steps auto-run and **stream as live cards**; the restart
+  gates; the operator types "go ahead" and the restart executes (no button);
+  ledger records each command + classification + the assent message.
+- Observability: the session ends with a digest listing what ran, what changed,
+  and any knowledge created; the learning view shows the run's contribution.
+- Parity: "provision an LXC with a service" via the runbook path matches the
+  reliability proven for the `pct_create` handler (free VMID, DNS, install,
+  verify), then destroy.
+
+## Open questions for the operator
+
+- **Reversible-low posture:** keep gating restarts/syncs in v1 (chosen), or
+  auto-run them once the classifier is trusted?
+- **Confirmation phrase:** per-action typed phrase for destructive, or a global
+  one? (Assent covers non-destructive; destructive keeps the typed phrase.)
+- **Assent detection:** rule/keyword match, or let the model judge assent (with
+  a re-confirm on ambiguity)? How strict — does "yeah do the restart but not the
+  upgrade" partially grant?
+- **Runbook authorship:** operator-authored only, or may Nomos propose new
+  runbooks (subject to approval) from successful ad-hoc sequences?
+- **Blast-radius threshold:** should a large blast radius force approval even for
+  otherwise-reversible actions?
