ask_operator: any agent can call it, answer routes by asker

new AgentRequest::AskOperator + AgentResponse::QuestionQueued on
the per-agent socket — same shape as the manager flavor, agent
gets the same wire surface (still uses the same operator_questions
table). agent_server::dispatch wires AskOperator through coord
.questions.submit(agent, ...) so the row's asker is the sub-agent
name; the ttl watchdog already in manager_server gets shared and
spawn_question_watchdog goes pub.

answer routing: operator_questions::answer now returns (question,
asker). post_answer_question + post_cancel_question + the watchdog
fire OperatorAnswered through new coord.notify_agent(asker, event)
instead of always notify_manager — the event lands in whichever
agent originally asked. notify_manager is now a thin wrapper.

agent socket plumbing: agent_server::start takes Arc<Coordinator>
instead of Arc<Broker> so dispatch has access to questions +
notify path; coordinator::{register_agent,ensure_runtime} take
self: &Arc<Self>. mcp::AgentServer grows the ask_operator tool;
allowed_mcp_tools(Agent) adds it; prompts/agent.md replaces the
'message the manager to ask the operator' guidance with the
direct tool description.

+- **Tag retention.** Every approval mints up to 5 tags in
+  `applied/<n>/.git` (`proposal/`, `approved/`, `building/`,
+  `deployed/`, plus `failed/` or `denied/`). Every successful
+  deploy adds one commit to `/var/lib/hyperhive/meta/.git`.
+  Both grow unbounded. A retention policy — keep all
+  `deployed/*` indefinitely, age-out `failed/` + `denied/`
+  after N days, drop `proposal/` + `approved/` + `building/`
+  once a terminal sibling lands — would keep the audit
+  trails browsable without forever-growth.
+
+- **Inert `nix flake lock` no-args call in `meta::sync_agents`.**
+  Still valid in current nix (resolves missing inputs without
+  bumping existing ones) but parallel to the deprecated
+  `--update-input` we just had to migrate. Worth keeping an
+  eye on; if it gets renamed too, sync_agents stops being
+  able to seed a fresh meta repo.
+
+- **Stream `nixos-container update` stdout into tracing.**
+  Today `lifecycle::run` calls `.output()` which buffers
+  until exit, so a 5-minute rebuild looks identical to a hang
+  in the journal — only the success/failure summary lands. Pipe
+  stdout + stderr line-by-line into tracing (or into the
+  per-agent live event bus when we know which agent) so the
+  operator sees `building '/nix/store/…drv'` / `copying path …`
+  in real time and can tell "slow" from "stuck." Same applies to
+  every other `nixos-container` shellout that takes
+  meaningful time (`create`, `update`).

 - `mcp__hyperhive__recv(wait_seconds?)` — drain one more message from your inbox (returns `(empty)` if nothing pending after the wait). Without `wait_seconds` it long-polls 30s. To **wait** for work when you have nothing else useful to do this turn, call with a long wait (e.g. `wait_seconds: 180`, the max) — you'll be woken instantly when a message arrives, otherwise return after the timeout. That is strictly better than calling `recv` repeatedly with short waits: lower latency on new work, fewer turns, no busy-loop. Never use a fixed `sleep` shell command for the same purpose.
 - `mcp__hyperhive__send(to, body)` — message a peer (by their name) or the operator (recipient `operator`, surfaces in the dashboard).
+- `mcp__hyperhive__ask_operator(question, options?, multi?, ttl_seconds?)` — surface a question to the human operator on the dashboard. Returns immediately with a question id — do NOT wait inline. When the operator answers, a system message with event `operator_answered { id, question, answer }` lands in your inbox; handle it on a future turn. Use this for clarifications, permission for risky actions, or choice between options. `options` is advisory: a short fixed-choice list when applicable, otherwise leave empty for free text. `multi: true` lets the operator pick multiple (checkboxes), answer comes back comma-joined. `ttl_seconds` auto-cancels with answer `[expired]` when the decision becomes moot.
 
 Need new packages, env vars, or other NixOS config for yourself? You can't edit your own config directly — message the manager (recipient `manager`) describing what you need + why. The manager evaluates the request (it doesn't rubber-stamp), edits `/agents/{label}/config/agent.nix` on your behalf, commits, and submits an approval that the operator can accept on the dashboard; on approve hive-c0re rebuilds your container with the new config.
 
-Need to ask the human operator a question (clarification, permission, choice)? You don't have direct operator access — ask the manager to surface the question on your behalf ("please ask the operator: …"). The manager has a channel for this.

 Durable knowledge: write to `/state/notes.md` (free-form) or any other path under `/state/`. That directory is bind-mounted from the host and persists across container destroy/recreate — claude's `--continue` session only carries short-term context, but `/state/` is forever. Read it back at the start of relevant turns to remember things across resets.
 
 Keep messages short — a few sentences each. For anything big (file listings, long diffs, transcripts, analysis): write the payload to `/state/<descriptive-name>` and `send` a short pointer ("dropped the cluster audit in /state/cluster-audit-2026-05.md, headline: 3 nodes over 80% mem"). The manager + operator can read your `/state/` from the host as `/agents/{label}/state/`. Sub-agent peers can't read each other's `/state/` directly — go through the manager if a payload needs to reach another sub-agent.
