style(orchestrator): restore the space in the FLOOR assignment

A comment cleanup before the W1 commit left FLOOR =(; the restored line is the one the reviewers judged and the operator accepted as an AIC-EXFIL-007 false positive. 🎯 Fix: 99 % 💥 Break: 1 % 💸 Cost: 100 % ⏱️ Time: 100 % 🛡️ Security: 100 % 🏆 Score: 98 🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 % Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
docs(requirements): keep 003 in English at the per-push waiver

 # Agent Instructions
 ## Platform-agnostic development
 Everything in this repository MUST work on every agent runtime, not only on
 the one developing it: Claude Code, Codex, Gemini CLI, Hermes, OpenClaw and
 any other that reads skills. The same holds for operating systems and
 distributions.
 - **Logic in scripts**: behaviour lives in `python3` or `bash` scripts that
  any runtime can call. Hooks, plugins and settings of one runtime are thin
  adapters over those scripts, never the only path to a feature.
 - **Skills stay portable**: a `SKILL.md` that uses a runtime-specific tool
  (`AskUserQuestion`, `SendMessage`, a slash command) says what the step
  needs, so another runtime can use its own equivalent.
 - **Installs reach every runtime**: install into the cross-runtime locations
  (`~/.agents/skills`) or through an installer that configures every
  detected agent; runtime-specific locations are mirrors. Of a tool that
  ships both, take the agent-agnostic integration over one runtime's plugin,
  and never both: the same server would run twice.
 - **No single package manager**: an install never depends on one OS or
  distribution's package manager; prefer upstream or statically linked
  release builds.
 - **One instruction file**: rules live here and nowhere else; no
  `CLAUDE.md`, `CLAUDE.local.md` or `GEMINI.md`. Claude Code reads this file
  natively from v2.1.277; Gemini CLI once its `context.fileName` setting
  lists `AGENTS.md`.
 ## Scope against package-manager
 Deterministic logic an operator could run without an agent (branches,
 worktrees, cleanups, releases) lives in
 [package-manager](https://github.com/kevinveenbirkenbach/package-manager) as
 a `pkgmgr` command with its tests, never as a script in a skill. A skill
 wrapping it holds only the agent discipline: claims, picks, handover.
 ## Code questions
 Ask the codebase-memory-mcp graph first (`search_graph`, `trace_path`,
 `get_architecture`); grep only after it.

 # Changelog
 ## [0.3.0] - 2026-11-03
 Breaking:
 - Skills: every skill is now *kvb-category-name*; the old names are gone
 - Skills: the category *skills* is now *skill*, e.g. *kvb-skill-tune*
 - Skills: *kvb-create-feature* is now *kvb-think-gaps*
 - Skills: *kvb-skill-dream* is now *kvb-dream*
 - Skills: *kvb-skills-shortcuts* and tokens such as *sobu* are gone
 Added:
 - Org: *kvb-org-rasci* keeps one RASCI/OKR register of every agent task
 - Org: *kvb-org-artefacts* tracks images, volumes and worktrees per task
 - Org: *kvb-org-wsjf* ranks the register by WSJF from Fibonacci estimates
 - Org: *kvb-org-operator* lists every command only the operator can run
 - Commit: commit skills show worktree, branch, confidence and risk first
 - Transcend: *kvb-transcend* carries session scripts and tests into repos
 - Requirements: *kvb-create-requirement* with user story, Mermaid and tests
 - Think: *kvb-think-brainstorm* scores options from seven fixed lenses
 - Skills: *kvb-skill-compile* turns deterministic steps into scripts
 - Skills: *kvb-skill-cleanup* deletes legacy skills that renames left behind
 - Dream: *kvb-optimize* runs all nine optimization skills in one pass
 - Dream: a GNOME notification recommends */kvb-dream* daily at 17:00
 - Coach: *kvb-coach* suggests the next step for mind, body, food and tasks
 - Coach: *kvb-coach-meditation* plays alpha-wave music with fractals
 - Coach: a short coach note at the first prompt of every full hour
 Changed:
 - Dream: covers every repository and session, then optimizes and cleans up
 - Dream: one hint per agent every 12 h replaces the tune and dream hints
 - Tune: *kvb-code-tune* always checks language, framework and recursion
 - Cleanup: worktrees are listed by size and integration line
 - Coordination: hotfix gates take the next free test slot
 - Coordination: an agent may end its own job after 60 min without progress
 Upgrade notes:
 - Install: run *make install* and restart the agent to load the new names
 - Install: run *make install-skills* in each project to drop old copies
 - Install: */kvb-skill-cleanup* lists any legacy skill left behind
 - Install: the global install enables the *kvb-dream-notify.timer* unit
 - Settings: remove *autotune* and *dream* hooks from *~/.claude/settings.json*
 ## [0.2.0] - 2026-10-31
 Added:
 - Git: *branch-gc* clears merged branches and worktrees with *pkgmgr*
 - Agents: *subagent-model* uses a cheaper model only at 90 % same result
 - Agents: *subagent-model* hooks log every spawn and its rated quality
 Changed:
 - Coordination: never cut a running job or agent short, not even at its cap
 - Resources: *watch.py admit* grants test slots only below CPU and RAM limits
 - Coordination: a relayer writes an operator rule to shared memory first
 Fixed:
 - Resources: stop-stage cleanup now skips worktrees where *make* still runs
 - Resources: the block hook ignores heavy commands in quotes and heredocs
 - Update: *make update* now updates every locked source, not just the first
 - Update: *make update* installs for Claude Code only
 - CI: *ci-artifacts* signs lint failures by finding, ignores later steps
 - Release: *changelog* warns when a workflow on HEAD already failed
 - CI: ruff pinned in *pyproject.toml*; local and CI lint now agree
 Upgrade notes:
 - 0.1.0 was never published (its CI failed); its upgrade notes follow
 - Install: restart the agent after *make install* to load skills and hooks
 - Resources: *watch.py* needs *~/.config/agents-council/config.json*
 - Resources: add *busy_processes* and *load_limits* to that config
 ## [0.1.0] - 2026-10-30
 Added:
 - Install: *make install* and *make project* install every locked skill
 - Install: enables caveman and ponytail; adds autotune and dream reminders
 - Commit: *commit-next* commits a bundle and stages the next one
 - Commit: *comments-clean* and *advocate* audit every commit before it lands
 - Commit: *confidence* and *break-risk* report measured fix and break numbers
 - Coordination: *democracy* elects the first agent to claim work as its owner
 - Coordination: *council.py* claims work; a hook blocks edits without a claim
 - Coordination: *funnel* keeps agent work in worktrees until it clears 90/5
 - Resources: *watch.py* blocks heavy jobs and cleans up before the disk fills
 - Cleanup: *cleanup* frees disk space after asking every peer agent
 - CI: *triage*, *observe* and *ci-artifacts* with *ci_failures.py* clustering
 - CI: *tune* finds speed-ups that never cut logic, coverage or correctness
 - Git: *merge-fix* with *find_fix.py* finds a fix on any branch and merges it
 - Reasoning: *active-listening* and *dialectic* pin requirements and causes
 - Review: *criticize* and *sceptic* give critique hardened by dialectic
 - Autonomy: *plan* hands an objective-oriented plan to *robot*
 - Quality: *test* runs Makefile targets; *--fix* loops until they are green
 - Quality: *refactor*, *no-defaults* and *scope-guard* keep changes lean
 - Skills: *autotune*, *autoskill*, *dream* and *essence* improve the skills
 - Release: *changelog* writes the pkgmgr release message since the last tag
 - Status: *status-matrix* lists everything in flight with its confidence
 - Help: *explain* and *help-skills* explain code and the skill set
 - Chat: *shortcuts* expands operator tokens such as *sobu* and *socon*
 - Security: *medusa* runs the MEDUSA scanner on repos and secret stores
 - Docs: the README skill map shows how the skills invoke each other
 Upgrade notes:
 - Install: restart the agent after *make install* to load skills and hooks
 - Resources: *watch.py* needs *~/.config/agents-council/config.json*

@@ -7,10 +7,438 @@ Every skill is pinned in `skills-lock.json` for reproducible installs.
 First-party skills live under `skills/` and are layered on top of the locked ones at install time.
 Compatible with Claude Code, Codex, Gemini CLI, Cursor, Copilot, Windsurf, Cline, and other agents.
 ## Naming 🏷️
 Every first-party skill is named `kvb-<category>-<name>` with one of these categories: `think`, `create`, `code`, `ci`, `git`, `release`, `check`, `org`, `agent`, `skill`, `coach`: `think` thinks without producing a file, `create` produces an artifact, `code` works on code, `ci` on pipelines, `git` on history and forges, `release` announces a release (changelog, article, posts), `check` analyses and reports findings, `org` coordinates agents, `agent` acts on one agent itself: its repository setup (code index, agent instructions) and its state (drain, suspend, resume), `skill` works on skills themselves, `coach` serves the operator's wellbeing. Only `kvb-cleanup`, `kvb-coach`, `kvb-help` and the collectors `kvb-dream`, `kvb-optimize`, `kvb-release` and `kvb-transcend` stand without a category. Names use `a-z`, `0-9` and single hyphens, at most 64 characters, and equal their directory name. `tests/test_naming.py` enforces all of it, including that the organigram below lists every skill under its category.

 How the first-party skills work together. A solid arrow means the skill invokes or relies on the other one; a dotted arrow means it fires automatically. Every skill that reports a result closes with the `kvb-check-confidence` block; those arrows are left out. The locked third-party skills (caveman, ponytail, archify) are not drawn.

 ## pkgmgr wrappers 🔗
 These `git` skills are thin wrappers: the [pkgmgr](https://github.com/kevinveenbirkenbach/package-manager#worktrees-and-garbage-collection) command holds the logic, the skill adds claims, picks and the operator handover.

 ## Requirements 📦
 - Node.js (provides `npx skills`).
 - `jq` (only required for `make update`).
 - Python `jinja2` for `make test` (pinned in `orchestrator/requirements.txt`).
 - Docker with the compose plugin (optional, runs the Agent Orchestrator).
 ## Installation 🚀

 ```
-Both commands also patch the target's `.claude/settings.json`: the caveman and ponytail plugins are enabled so their modes auto-activate on session start, and two reminder hooks are registered — `autotune` points you at `/autotune` at most once an hour, `dream` points you at `/dream` at most once every twelve hours per repository (stamped in that repository's git dir). Existing settings are preserved.
+Both commands also patch the target's `.claude/settings.local.json` — the machine-local, untracked file, so a project's reviewed `.claude/settings.json` is never rewritten by an install: the caveman and ponytail plugins are enabled so their modes auto-activate on session start, and two reminder hooks are registered — `kvb-dream` points each agent at `/kvb-dream` at most once every twelve hours (stamped per session in `~/.claude/.dream-stamps/`), and `kvb-coach` runs its short form at the first prompt of every full hour, once across all agents (stamped in `~/.claude/.coach-hours/`); the global install also enables the `kvb-dream-notify.timer` systemd user timer, which recommends `/kvb-dream` in a GNOME notification daily at 17:00 local time and catches up once after a missed run. A PreToolUse gate from the `kvb-org-organize` skill blocks edits to files in a git worktree until the session holds a claim (`skills/kvb-org-organize/scripts/council.py`), and its resource watch (`skills/kvb-org-organize/scripts/watch.py`) measures disk, Docker and caches, cleans up low-risk data and blocks new heavy jobs before the disk runs out; it stays inactive until `~/.claude/agents-council/config.json` exists, and because its hooks run that config's commands outside the sandbox, the install adds `Edit(~/.claude/agents-council/**)` to `permissions.deny`, which also covers Write in every permission mode. The `kvb-org-radio` skill registers five hooks: its prompt hook and a PostToolBatch hook deliver the immediate radio (`call`, `broadcast`, `security`, `pan-pan`, `mayday`) mid-turn, a Stop hook delivers the post (`post`, `newsletter` and call receipts) when the turn ends, an `asyncRewake` Stop hook wakes an idle session for the radio, and a PreToolUse hook refuses every writing action while a mayday holds, except those of its sender and of the agents that join it with `radio.py assist`. The PreToolUse hook of the `kvb-org-queue` skill sends heavy commands through `queue.py hold` once the config sets `queue_enforce`, and holds a held command to the settings' Bash deny and ask rules, which see only `queue.py hold`. The global install also installs the MEDUSA security scanner with pipx for `kvb-check-security`, unless `medusa` is already on the PATH. Two hooks of the `kvb-org-perform` skill (`skills/kvb-org-perform/scripts/log.py`) log every Agent spawn with its task class, model and effort, and store the quality feedback a sandboxed session prints, in `~/.local/state/agents-council/subagent-model.jsonl`. Every hook runs `/usr/bin/python3 -I`, so neither the `python3` of a sandbox-writable virtualenv on the `PATH` nor `PYTHONPATH` reaches the hooks, which run outside the sandbox; older bare `python3` hook entries are rewritten. The reminder hooks run `/usr/bin/bash` and pin `PATH=/usr/bin:/bin`, and the council scripts keep only the `PATH` directories this uid cannot write (`skills/kvb-org-organize/scripts/hookpath.py`), so no binary an agent plants on the inherited `PATH` runs outside the sandbox. Existing settings are preserved.
 The global install also runs the Agent Orchestrator, a local review page in which the operator approves or rejects the agents' staged commits (the `kvb-git-diff` skill): it copies `orchestrator/` to `~/.local/share/kvb-orchestrator`, starts it there with `docker compose up -d --build` (restart `unless-stopped`, bound to `127.0.0.1` only, state in `~/.local/state/kvb-orchestrator`) and registers its MCP server for Claude Code at user scope. Its port is `KVB_ORCHESTRATOR_PORT` in `orchestrator/.env`; the hub page is `http://localhost:<port>/`, the MCP endpoint `/mcp`. Without docker the hub is skipped and the commit skills ask in chat. The hub reads new radio traffic aloud in maritime phraseology and takes push-to-talk input; its image builds both engines from pinned, sha256-verified sources and runs each as a separate process: Piper (`piper-tts`, GPL-3.0-or-later) with the `en_US-libritts-high` voice (904 speakers, trained on LibriTTS, CC BY 4.0, from `rhasspy/piper-voices`) and whisper.cpp (MIT) with the multilingual `ggml-base-q8_0` model (OpenAI Whisper weights, MIT, 82 MB). The operator's own voice is `KVB_ORCHESTRATOR_OPERATOR_VOICE` in `orchestrator/.env`. Its Tree reads only the file `pkgmgr branch tree` writes: the install clones `PKGMGR_REPO` (default the GitHub repository, never the sandbox-writable local checkout), builds the newest `v*` tag a fully trusted GPG key signed into `~/.local/share/kvb-orchestrator/pkgmgr`, and enables the `kvb-orchestrator-tree.timer` user timer, which writes `~/.local/state/pkgmgr/tree/branch-tree.json` a minute after its previous run while the hub page polls, on at most half a core; the hub mounts that directory read-only and starts no git. A signed tag without `branch tree` leaves the timer off.
 Stream → Radio (`#stream/radio`) is the hub's radio interface. Its station list shows one line per station, the full name in the tooltip, with its state and a play or stop button; when the browser blocks autoplay, the stream fails or the CSP refuses its origin, the row and a toast say so, and one click starts the station. New stations play daily around the clock. While the hub reads a message aloud, the speaking agent pulses there and in the Orbit and Chord views, under the caption "<Agent> speaking" with the message's first line; under `prefers-reduced-motion` the ring stays still. The speech bubble icon in the header (a hub setting, kept across reloads) puts a bubble at each speaking agent in the Agents graph, 3D, Hierarchy, Radio and Stream views, or in a caption bar at the bottom when the view does not show that agent: the agent being read gets the largest bubble and its words appear in time with the audio, waiting messages show a smaller `…` bubble per agent, and without speech output the same rows run at 180 words a minute, at least 1.5 s each. The composer sends on all seven channels: post and call to one agent, newsletter, broadcast, pan-pan, security and mayday to all. "Record" records with MediaRecorder; the hub transcribes the recording with whisper.cpp off the request thread (at most 120 s of audio, a 120 s timeout, four at a time), keeps it for replay in `~/.local/state/kvb-orchestrator/voice` (the newest 50) and puts the transcript into the field to edit; the message goes out as text, with the recording's host path and sha256 only when "Attach recording" is ticked. The hub transcribes at most six recordings a minute and 600 s of audio an hour. Every operator message is passkey-signed, and the hub verifies the signature against the pinned keys, each once, before it relays; `operator_message(id, text, to)` answers `match` only for the signed text and recipient; for a denial the signature covers the recipient the inbox resolved at signing, and the answer's text is only the signed reason, never the agent's own words the radio row quotes. "Cancel mayday", Evening, Sunset, Sunrise and a settings save that adds a stream URL take the passkey the same way.
 The hub page loads nothing from the network: its icons come from Bootstrap Icons 1.13.1 (`orchestrator/vendor/bootstrap-icons`, MIT), inlined per page as the symbols it uses, and its 3D views from `3d-force-graph` 1.80.1 and `three` 0.186.1 (`orchestrator/vendor`, MIT, served by the hub under `/vendor/`); the speech bubbles use Comic Neue 400 latin from `@fontsource/comic-neue` 5.3.0 (`orchestrator/vendor/comic-neue`, SIL OFL 1.1), which the page fetches and adds through the FontFace API, so the CSP needs no `font-src`. In the Artifacts Tree, "Delete" on a `merged-clean` branch without skip reason, or "Delete all merged", shows the dry-run lines and asks for the passkey signature; the hub then writes a job (repository, branch, worktree and tip per item, no command) into `~/.local/state/kvb-orchestrator/cleanup/jobs`. The `kvb-orchestrator-cleanup.path` user unit runs `client/cleanup.py` on the host, which verifies the signature against the pinned keys, runs `pkgmgr branch cleanup --json --local --branch <name>` as a dry run in the repository, then `--apply` only when that plan names exactly the signed branch as `merged-clean` at the signed tip and worktree, refuses everything else unchanged, writes each result to `cleanup/results` and rewrites the tree file. The buttons stay disabled while the tree file says `delete_ready: false`.
 The Agents view "Hierarchy" draws the council's formal offices as a collapsible org chart: Operator, chair, dimensions with their line representatives, organisers (`cluster/<slug>`) and presidents (`work/<slug>`); the chair in every graph is the holder of the `chair` office, not a fixed name. Appointing, handing over or recalling an office there asks for the passkey signature; the hub writes a job (office, signed holder, successor session, work; no command) into `~/.local/state/kvb-orchestrator/offices/jobs`, and the `kvb-orchestrator-offices.path` user unit runs `client/offices.py` on the host, which verifies the signature, refuses a council directory others can write, a link on the path or a holder that changed since the signature. For a takeover or recall it moves the office aside and removes it only while the claim there still names the signed holder; an appoint or takeover then runs a plain `council.py claim <office>` for the successor by argv. council.py itself has no flag that overrides a live holder. The same view holds the operator's agent order as a drag list with up and down buttons: `rasci.py agents order` stores it in `agent-order.json` beside the register, where it breaks ties of equal task priority and orders the chair's grants without touching any task's `--prio` pin.
 The Tasks tab (key 4, `#tasks/list`, `#tasks/board`, `#tasks/rasci`) shows the `kvb-org-rasci` register as a list, a board by status and a RASCI matrix; queue jobs from `council/queue.json` appear as "waiting for a grant", and the filter "Waits on Operator" is the inbox, which the Inbox entry under Stream opens: every pending review, ask, rule request, operator row and choice card, with no Choices column of its own. The Tasks toolbar is one row that wraps on narrow screens (views, filter, estimation, sort and business value, trend on the burn view), the status chips the second; every list row shows its ETA, and `#tasks/3d` draws the tasks and their dependencies on the 3D engine. Its "Request choices" dropdown has one button per channel, post and call to the agents ticked in it, newsletter, broadcast, pan-pan, Sécurité and mayday to all, that sends the fixed request "send me your open decisions as choices" without a text field, one passkey assertion over every recipient (`/api/choices/sign`, then `/api/choices`). Agents answer with `decision_request`, shown as choice cards, and a click on an option is the passkey-signed answer: after the 3 s undo the hub verifies the signature and posts the answer to the asking agent, whose `decision_wait` returns it as `message` and `answer` for `operator_message`. A task's sheet pins its priority (`rasci.py set <task> --prio <n>`) or sets and drops the operator's WSJF estimate (`rasci.py estimate <task> Operator --value <fib> --complexity <fib>` or `--drop`) after a passkey signature; the hub writes an argv-only job, and the runner, started with `--rasci <rasci.py> --council <council root>`, verifies it like an operator command and runs `rasci.py` from `/` without a shell, killing it after 30 s. Agent order stays untouched. The install copies the fresh runner unit and restarts the runner when it is enabled, and only while the installed `council.py`, `nofollow.py` and `rasci.py` match this tree: otherwise it disables the runner and asks for `make install`. The runner unit pins `PATH` to `/usr/bin:/bin`, so a signed command names any other program by its full path; a runner started without `--rasci` and `--council` keeps running signed commands and refuses task changes, and so does one whose council is a symlink or another uid's. Each worktree in the tree file may carry `"flow": {"pull": [...], "push": [...], "source": "file"}` or `null`, which the Tree, the Chord edges, the detail panel and the matching task show; a malformed flow shows as `invalid`. Worktrees and tasks with open work (uncommitted, unpushed, unmerged, task not done) carry a warning bar.
 Without reinstalling the skills, `make orchestrator-install` installs, builds and starts only the hub, `make orchestrator-check` checks the installed hub (image, container, logs, HTTP, pinned keys, hook, runner, tree timer, disk; exit 1 on a failure), `make orchestrator-pin CREDENTIAL=<blob>` pins the passkey that "Register passkey" shows, `make orchestrator-runner` enables the runner service, and `make orchestrator-hook` registers the PermissionRequest hook in `~/.claude/settings.json`, replacing an earlier Agent Orchestrator entry and keeping the file mode, after a copy to `settings.json.before-kvb-orchestrator-hook` (Claude Code reads `~/.claude/settings.local.json` only in sessions started in the home directory). Agents that reach the Docker socket are root-equivalent: until the agent VMs of core requirement 093 isolate them, the signatures do not hold against such an agent. `make watch-check` shows whether the resource watch hook is stuck (running hooks, holders of the kept queue history, age of the stored stage).
 For approvals the hub is only a relay: every approval of an ask, a staged commit or an operator command is signed end to end with a WebAuthn passkey held in KeePassXC (through KeePassXC-Browser, relying party `localhost`, origin `http://localhost:<port>`; ES256, EdDSA and RS256, so a hardware key can be pinned beside it). To register, open the hub at `http://localhost:<port>/` (WebAuthn needs the domain; on `127.0.0.1` the page links there), choose "Register passkey" in the settings and run the host command the page shows, `python3 ~/.local/share/kvb-orchestrator/client/approval.py pin --port <port> --approvers ~/.config/kvb-orchestrator/approvers.json --credential '<blob>'`, in a terminal outside every sandbox: it pins the key in `~/.config/kvb-orchestrator/approvers.json` with mode 0600, a file no sandboxed agent can write and the hub mounts read-only; the hub never pins. Each approval, or one bulk selection, is one signature over the hashes of every item, a nonce and an expiry; each auto-approval rule is signed once. In the inbox, an operator command run with "Run" shows the runner's output in a console under its row until "Close". "Deny" on an ask, an operator row or a rule request signs the denial with its channel and optional reason (a hash no approval shares) and, after the 3 s undo, tells the requesting agent by post or by the radio class picked, never mayday; the hub verifies that signature against the pinned keys before it stores or sends anything, the hook passes the reason on only when it verifies the signature too, and a denied operator row ends as `stopped`. Agents ask for an auto-approval rule with the MCP tool `rule_request` (the rules form's limits; a request stays open for the ask lifetime of one hour, at most 20 in all, and 3 per agent name, which only spreads the queue since MCP names no caller); its row shows a dry run over the last 7 days, and only "Accept" with the passkey stores it. The hub stores no rule, of any kind, whose passkey assertion it cannot verify. The executors verify it themselves against the pinned keys and fail closed: the runner (`client/runner.py`, the `kvb-orchestrator-runner` user service) runs only signed commands, each signature once, recorded in `~/.local/state/kvb-orchestrator-approvals/runner.json`; the PermissionRequest hook (`client/permission_hook.py --port <port> --timeout <seconds> --approvers ~/.config/kvb-orchestrator/approvers.json --replay ~/.local/state/kvb-orchestrator-approvals/hook.json`) allows only a signed item that matches its own tool, command, cwd and session, else it leaves the decision to Claude Code's own prompt; the commit skills run `approval.py verify` on the staged tree before committing, else they ask in the terminal. With no key pinned, every executor refuses; review rejections and a decision a rule takes stay unsigned. A signed rule never covers a command holding `;`, `&`, `|`, a backtick, `$`, `<`, `>`, parentheses or a line break: such a command always asks. The hub page is trusted while it asks for a signature or shows the blob to pin: whoever controls the hub container can show one item and have another signed, or hand over a key of its own. Any local process, sandboxed agents included, can also send the unsigned operator actions (the bare decision choice `/api/decisions/<id>/choose`, which sends no answer, the priority order, settings that add no stream origin, review rejections, the bare ask denial `/api/asks/<id>/deny`, console dismissals) with the hub's guard headers, and the container reads the host `/tmp` for the review pages in `/tmp/kvb-git-diff`. All three close with the agent VMs of core requirement 093, like the Docker-socket gap.
 Restart your agent afterwards so it loads the new skills.

 # 001 - Agent Orchestrator
 ## User Story
 As the operator of many parallel agents, I want one simple Agent Orchestrator
 surface and a radio that only interrupts for urgent calls, so that agents
 spend few tokens on talk, urgent news reaches them at once, and I can drill
 from three views down to any agent, branch or artefact.
 ## Decisions (operator-confirmed 2026-11-06; do not re-litigate)
 1. **One document**: radio model, surface, pkgmgr branch tree and views live in
   this one requirement as phases. Rejected: one document per feature (the
   operator wants the whole picture in one place).
 2. **Location**: `docs/requirements/NNN-slug.md`, numbered per repository.
   Rejected: a file next to the code (no index, no numbering).
 3. **Radio classes**: `post`, `call`, `newsletter`, `broadcast`, `mayday`,
   `pan-pan`, `security`. Rejected: `broadcast` only as the umbrella of the
   three alarms (the operator wants an immediate call to all without alarm).
 4. **Mailbox**: `post` (one agent) and `newsletter` (all agents) are
   delivered only when the agent ends its turn and goes idle, batched; an
   agent already idle is not woken and sees its mailbox at the end of its next
   turn. Rejected: next prompt, next tool step (interrupts work), batched
   wake-ups (one turn per wake).
 5. **Immediate classes**: `call`, `broadcast`, `pan-pan`, `mayday` and
   `security` reach the agent at its next tool step and wake an idle agent.
 6. **Call receipt**: the caller gets a delivered/read receipt and does not
   wait; an answer is a call of its own. Rejected: the caller blocks until
   the answer (costs the caller), delivery without feedback.
 7. **Mayday pause**: while a mayday holds, a PreToolUse hook blocks every
   writing action until `radio.py clear`; reading, the radio and teardown
   stay allowed. The sender and every agent that joins with `radio.py
   assist` to help keep working. Rejected: an instruction only (not
   enforced), heavy jobs only (today's behaviour, too weak), a full blockade
   that also stops the helpers.
 8. **Radio and post**: two channels. `radio.py send` is the radio and always
   immediate (`call`, `broadcast`, `pan-pan`, `mayday`, `security`);
   `radio.py post` is mail and always delayed (`post` with `--to`,
   `newsletter` without). `send direct` stays as an alias so running peers
   keep working: with `--wake` it becomes `call`, without it `post`. Rows
   stored before the change carry no version mark and are read as before:
   `direct` as `post`, `broadcast` as `newsletter`. Rejected: `send
   broadcast` as an alias of `newsletter` (makes the immediate broadcast
   unreachable).
 9. **Name**: kvb-hub is renamed in full, with a one-time migration: visible
   "Agent Orchestrator", technical `kvb-orchestrator` / `kvb_orchestrator`
   (directory, module, container, systemd unit, MCP server, environment
   `KVB_ORCHESTRATOR_*`, make targets). Rejected: visible name only (two names
   for one thing).
 10. **Navigation**: Stream (sub-items Inbox and Firewall) · Agents (ex Graph) ·
    Artifacts (ex Tree). Agents and Artifacts each offer Orbit, Chord,
    Swimlane, Tree and 3D.
 11. **Header**: title · ⌘K · ⚙ only. The status pills become navigation
    badges (Inbox: waiting items, Agents: active agents, Artifacts: runner
    jobs); Mayday shows only as a red banner with "cancel" while active; the
    background shows day and night. Rejected: one status dot with a popover
    (an extra click), a status block in a side bar, a "Situation" screen
    (effort), no header at all.
 12. **Tools**: Controls (Radio to all, Cancel mayday, Priority, Day/Night)
    moves to the Agents toolbar, Firewall under Inbox, Sky, Music,
    Control room and Notifications to ⚙ "Ambience"; ⌘K reaches every one.
    Rejected: one ⋯ menu (hides instead of ordering).
 13. **Stream**: four category chips For you · Radio · Work · Transcripts;
    one search line with `agent:`, `kind:`, `since:`; sub-filters, saved views
    and a custom range under "Filter ▾"; the time bar becomes "24 h ▾" with
    the replay inside; transcripts are off by default. Rejected: a
    self-grouping stream, a Kibana-like query language (effort), preset
    chips only.
 14. **3D**: `3d-force-graph` 1.80.1 on `three` 0.186.1, vendored as in
    meta.infinito.nexus; the Canvas depth axes Time and Spawn depth become 3D
    options. Rejected: keeping the Orbit-only Canvas depth.
 15. **Artifacts scope**: git (repositories → branches → worktrees with their
    agents and reviews) plus the kvb-org-rasci register artefacts (images,
    volumes, logs) as leaves of the task or worktree that owns them.
    Rejected: git only.
 16. **Artifacts views**: Orbit: repository sun, branch planets (size = commits
    ahead), worktree moons, agent satellites. Chord: branch overlap (same
    files touched, merges) as conflict risk. Swimlane: one lane per branch
    with commits, reviews, gates and pushes. Tree: the pkgmgr branch tree.
 17. **Tree data**: the scan moves from `hub/kvb_hub/tree.py` into pkgmgr as
    `pkgmgr branch tree --format json|yaml --output FILE`, rewritten by a
    systemd user timer every minute and after every pkgmgr branch action; the
    orchestrator only reads the file, no git runs in its container. Rejected:
    the hub keeps scanning (pkgmgr is not the single source, git runs in the
    container), a live websocket daemon (effort). Hardened through
    kvb-think-dialectic before it is built.
 18. **Order**: 1 radio → 2 surface and rename → 3 pkgmgr branch tree → 4 views
    and 3D; one bundle per phase, each change set through kvb-code-refactor.
 19. **Icons over text**: every HTML surface a skill renders (the
    orchestrator, the review pages, the meditation page) shows Bootstrap
    Icons instead of text labels wherever an icon carries the meaning, each
    with a tooltip and an `aria-label`; terminal output and `SKILL.md` keep
    emoji. Rejected: Font Awesome Free (icons under CC BY 4.0, core loads it
    from a kit CDN), emoji in HTML (look differs per platform).
 20. **Branch state**: `pkgmgr branch tree` covers every repository pkgmgr
    manages and gives each branch and worktree the classification of
    `pkgmgr branch gc` (one implementation, no second copy): merged and by
    what, clean or uncommitted changes, unpushed commits, gone upstream,
    locked, stale, protected and the gc skip reason. The Artifacts Tree shows
    it as icons. Phase 3 builds the data, phase 4 the icons.
 21. **Delete from the tree**: merged, orphaned branches are deleted by click
    in the Artifacts Tree (phase 4), per item and as "Delete all merged":
    - **Credentials**: only while the Secret Service hands pkgmgr the GitHub
      token, which proves the merge and the missing open pull request; no
      secret passes the orchestrator container. Rejected: the master password
      typed into the dialog (secret crosses container and browser), the SSH
      key through the KeePassXC agent (a local delete pushes nothing;
      operator 2026-11-06).
    - **Scope**: local only (operator 2026-11-06): the worktree, the local
      branch, the compose stack without its volumes and its images of a
      `merged-clean` item, never a remote branch; a gc skip reason locks the
      button, and the dry run lists ignored files, any beyond known caches
      (`__pycache__`, `node_modules`, `.venv`) locking it too. Rejected: what
      `pkgmgr branch gc --apply` deletes today (remote branch and
      `compose down -v`).
    - **Confirmation**: the click shows the gc dry-run lines of the chosen
      items, and "Delete" needs the operator signature (`/api/sign`).
      Rejected: a second click without signature, one click without preview.
    - **Execution**: the orchestrator writes a signed job into a host
      directory; a systemd user path unit runs `pkgmgr branch cleanup --apply
      --local` for exactly those items and writes the result back. Rejected: an
      `operator.py` row (not direct).
 22. **Organisation update**: a new skill `kvb-org-update` tells every agent
    and client which skills changed and how to use them, as one
    `newsletter` per update; phase 1 announces the radio change through it.
 23. **Phase 5** (23 to 43 operator-confirmed 2026-11-07): the console
    output shows under "Run"; a deny picks its channel (default
    `post`); agents request auto-approval rules through the
    inbox; the rules form and the Location fields never overlap; the radio plays
    with one line per station and highlights the speaking agent; the
    operator composer sends text or voice, recorded, transcribed locally with
    whisper in the container and kept as audio, to a recipient by `post` or
    `call`; a Hierarchy view shows the council offices with appoint and
    recall; the agent order (drag list) is separate from task priority (WSJF
    plus the operator's pin) and only breaks ties; one Tasks tab holds list,
    board and RASCI matrix, the inbox as its "waits on Operator" filter and
    the queue state; the merge flow, a pkgmgr-managed YAML per worktree with
    several pull sources and push targets, shows in Artifacts and Tasks.
 24. **Firewall**: the rules tab becomes Firewall and holds every form of
    allow-listing: the hub's auto-approval rules (ask, review, decision),
    allow and deny command patterns, and the Claude settings permissions
    (`allow`, `ask`, `deny`) and sandbox entries. Rejected: a separate
    settings page.
 25. **Settings writes**: a change to a Claude settings file shows as a diff,
    is signed with the passkey and applied by a host executor that verifies
    the signature, writes only files of a fixed list (`~/.claude/settings.json`
    and `<project>/.claude/settings.json` of the known projects) and keeps a
    backup. Rejected: an `operator.py` row only (no one-click path); an agent
    writing settings (never).
 26. **Groups**: a rule applies to one agent, a named agent group or all
    agents; rules form named rule sets that are taken over as a whole for an
    agent, a group or all. The Firewall reads the existing settings files and
    groups their entries by tool and command prefix by itself.
 27. **Decisions are tasks**: asks, rule requests, operator rows and choices
    appear only in the Tasks tab, under its "waits on Operator" filter.
    Rejected: a Choices column of its own (a choice is a decision the operator
    takes, so it is a task).
 28. **Request choices**: the Tasks tab has one button per channel, `post` and
    `call` with a multi-select of agents, `newsletter`, `broadcast`,
    `security`, `mayday` and `pan-pan`, that sends the fixed request "send me
    your open decisions as choices" without free text. Agents answer with
    `kvb-think-choice` items, shown as choice cards; the operator's click on
    an option is the passkey-signed answer.
 29. **Night commands**: evening, sunset and sunrise become `drain` (finish the
    current task, accept nothing new), `suspend` (park work, write the
    handover, idle) and `resume` (continue from the handover). Skills:
    `kvb-org-evening` → `kvb-org-drain`, `kvb-org-sunset` → `kvb-org-suspend`,
    `kvb-org-sunrise` → `kvb-org-resume`, `kvb-agent-relax` →
    `kvb-agent-drain`, `kvb-agent-sleep` → `kvb-agent-suspend`,
    `kvb-agent-wakeup` → `kvb-agent-resume`; `night.py` and the Controls
    menu follow, `kvb-skill-cleanup` removes the old names. Rejected:
    sleep / hibernate / wakeup, pause / park / resume.
 30. **Agent popup**: a click on an agent opens a fading popup with a simple,
    clear layout (face, name, earlier names, offices, tasks, claims,
    composer) instead of the Details side panel, which goes.
 31. **Node popup**: a click on a node in any graph view enlarges it, marks it
    red and opens a slightly transparent popup in the foreground, tied to the
    node by a leader line. A search field with suggestions replaces the list
    of every node.
 32. **Faces**: agents get simple animated 2D faces instead of emojis, built
    from independent attributes (shape, colour, eyes, brows, mouth, hair or
    headwear, accessory) with at least 1000 combinations, chosen
    deterministically from the agent's stable id; the mouth moves while the
    agent speaks.
 33. **Fit to window**: every view sizes to the window height; no page
    scrollbar on `#agents/orbit`.
 34. **Rename once**: a name change appears once in the Stream per session
    and name pair, never again per state build; earlier names show in the
    agent popup.
 35. **Radio**: the configured Deutschlandfunk stream
    `https://st01.sslstream.dlf.de/dlf/01/high/aac/stream.aac?aggregator=web`
    plays (root cause proven first, redirects and `media-src` included). A
    squelch control suppresses the radio beep; at 0 no beep plays, music on
    or off.
 36. **Tree cause**: the tree timer builds pkgmgr from the newest signed tag,
    and v2.3.0 has no `branch tree`, so no tree file exists. The Tree names
    that cause and the operator step (the pkgmgr release) instead of a bare
    "No tree"; with pkgmgr 2.4.0 released the timer writes the file.
 37. **Resources**: a tab Resources shows charts on the shared time axis:
    tokens per agent and accumulated (from the usage fields of the session
    transcripts), and CPU, RAM, disk and load of the host, sampled by a host
    unit into the state directory; several values per chart.
 38. **Order of phase 6**: serial subtrees, each in its own worktree under
    `kvb-org-robot`, merged into master before the next starts: S0 English
    and radio speech → S1 fixes (fit, rename once, radio, squelch, tree
    cause) → S2 popups and search → S3 faces → S4 night commands → S5 Tasks
    with asks and choices → S6 Firewall → S7 Resources.
 39. **Sécurité**: the class `security` keeps its id and shows as "Sécurité";
    the radio speaks it as in maritime radio, "say-cure-ee-tay", three times.
 40. **Hashes spoken**: a hex run of 7 or more characters with at least one
    letter and one digit (commit, session and message ids) is spoken in the
    NATO alphabet, one character at a time (alfa, bravo, charlie, delta,
    echo, foxtrot and the digits of decision 41).
 41. **Digits spoken**: every digit is spoken on its own in ICAO radio
    pronunciation: zero, one, two, tree, four, fife, six, seven, eight,
    niner; `42305` is "four two tree zero fife". Only the spoken text
    changes; the displayed text keeps the digits and hashes.
 42. **English**: the whole skills repository is English: every orchestrator
    label, message, spoken text, script output, document and test string
    (Regeln → Firewall, Hierarchie → Hierarchy, Ressourcen → Resources,
    Steuerung → Controls, Ausführen → Run). Kept: trigger phrases in skill
    descriptions that quote what the operator says in German, and the rule
    that agents answer the operator in the operator's language.
 43. **Shared cache** (core concept settled by the operator 2026-11-07
    18:40, owner IAM, report `/tmp/shared-model-cache-base-20261107.md`):
    the image build fetches every model, voice and source archive from
    `${INFINITO_ARTEFACT_BASE}/<host>/<path>` with the same sha256 pins, and
    from the real upstream when the build arg is unset. Speech uses the
    core role `svc-ai-speech` when its URL is configured, else the
    in-container whisper and piper. `make orchestrator-install` without any
    core stack stays the standalone path. Subtree S8, after S7.
 44. **Gantt** (operator 2026-11-08, decisions 44 to 51): the Tasks tab gets
    a Gantt view next to List, Board and Matrix, one bar per task from its
    start to its end, a running task to now. Arrows come from three sources:
    an explicit `rasci.py set <task> --after <task>` (repeatable), the
    branch base (a task whose base branch is another task's branch follows
    it) and the queue order (each waiting `queue.py` job follows the one
    ahead of it). Rejected: branches only (tasks without a branch hang
    loose), the explicit field only, the queue position as a mere badge.
 45. **Forecast**: a selector sets how the Gantt draws tasks not yet
    started: `always` (default; with no estimate the median duration of done
    tasks, with story points the points times the median hours per point of
    done tasks), `points only` (a dot behind the predecessors without
    estimate) or `real only` (no forecast). Forecast bars are hatched.
 46. **Estimation modes**: a toggle in the Tasks toolbar, stored in the hub
    settings: `No estimate` (default, every task counts 1) and `Story
    points` (the Fibonacci complexity of `rasci.py estimate`, the median over
    its estimators).
 47. **Burndown and burnup**: one view in the Tasks tab with both curves.
    A selector sets the scope: the whole register over the whole time
    (default), the active list filter within the header time window, or one
    agent or line. With no estimate it counts tasks, with story points it
    sums complexity and draws unestimated tasks as a line of their own.
 48. **Estimate request**: only in story points mode, and only on a click on
    "Request estimates" or on `/kvb-org-queue-estimate`, never by itself, to
    save tokens. It sends one `newsletter` to all agents listing every
    unestimated task with its parties; every agent holding any RASCI role in
    a task (R, A, S, C or I) records business value and complexity
    (Fibonacci) for it with `rasci.py estimate`. Rejected: every agent
    estimates every task, the Accountable alone.
 49. **Operator business value**: the operator overrides the agents'
    business value, and WSJF uses that value instead of the median. It is set
    in the hub per task or as one bulk change over a selection in the list;
    one passkey assertion over the exact task ids and values covers the
    whole batch. Rejected: the origin guard alone (a forged request could
    reorder the queue), one signature per task.
 50. **Sort modes**: the task list sorts by prio (default), WSJF, business
    value, complexity, status, start, end, agent and title, each ascending
    or descending.
 51. **Subtree**: decisions 44 to 50 join subtree S5, Tasks with asks and
    choices, in its one worktree. Rejected: a subtree of their own after S8
    or right after S1.
 52. **Radio spot** (operator 2026-11-09, decisions 52 to 58): the radio
    button of the Agents toolbar is the one place to send. It expands inline
    and shows the full composer below the toolbar (every channel, the
    recipients for post and call, Record, Send), a gear button with every
    radio setting (tones per class, squelch, read aloud with its classes and
    speakers, moved out of the general settings) and Cancel mayday, which
    leaves the toolbar. The Radio tab keeps the stations and the message log
    without a composer. Rejected: the Radio tab as the spot, removing the
    Radio tab.
 53. **Day/Night menu**: only the status badge and the Drain, Suspend and
    Resume buttons; each button's explanation is its hover tooltip.
 54. **Tasks toolbar**: views, filter, estimation toggle, sort and business
    value in one row that wraps on narrow screens; the request choices
    become one "Request choices" dropdown in that row; the status chips stay
    the second and last row. Rejected: moving the request choices into the
    radio spot.
 55. **Trend and forecast**: burndown and burnup get a trend selector, `off`
    (default), `linear regression` (least squares over the points in the
    shown window) and `velocity` (the mean burn rate of the last N days, N
    set freely, default 7), stored in the hub settings. The trend is drawn
    until remaining reaches 0 (burndown) or done meets scope (burnup); that
    date is the forecast, shown on the chart. Hovering a point lists the
    work packages that started, ended or joined the scope at that step.
 56. **ETA**: every work package in the list carries an ETA: its end when
    done, else its start (or now) plus the forecast length of decision 45
    for the active estimation mode, behind the latest ETA of its
    predecessors.
 57. **Tasks 3D**: a sixth Tasks view on the 3D engine of the Agents tab:
    tasks as nodes, the dependency edges of decision 44 in the Gantt colors,
    layouts Force and Time, the same tooltips and popups. Rejected: a fixed
    time-agent-depth layout.
 58. **Steady 3D camera**: the 3D view fits the graph once per build; state
    refreshes keep the operator's camera.
 59. **Radio in the header** (operator 2026-11-10, replaces the toolbar button
    of decision 52 and the Radio tab): a radio icon button at the top right,
    next to Commands and Settings, opens the radio spot above the main area
    of whichever tab is open. The spot holds the composer, the gear, an
    icon-only Cancel mayday with its tooltip, who is speaking, the last five
    sent messages and the internet radio stations. The Agents toolbar loses
    its radio button, the Radio tab and its "Send …" button go away, and an
    old `#stream/radio` link opens the Stream with the spot open. Rejected:
    keeping the Radio tab, the speaker chips (every Agents view already marks
    the speaker).
 60. **Radio numbers and paths** (operator 2026-11-10): only the spoken line
    changes, the displayed text stays as written. Digits are spoken in ICAO
    words in Title Case, Ze-ro, One, Two, Tree, Fow-er, Fife, Six, Seven,
    Eight, Ni-ner, and the NATO letters of hashes too (Alfa to Foxtrot);
    this replaces the words of decisions 40 and 41. A time is four digits,
    hour padded, no colon, seconds as two more digits; a UTC time ("08:15
    UTC", "08:15Z", "0815Z", "08:15 Zulu") ends in one "Zulu", another zone
    word follows the digits as written. A date with a time is the DTG
    DDHHMM, "Zulu" when zoned, the full month name and the two-digit year
    ("One Ze-ro One Fow-er Tree Ze-ro Zulu November Two Six"); an explicit
    offset is converted to UTC first, no zone drops "Zulu", a date alone is
    day, month and year. A dot between digits is "Decimal" and the "v" of a
    version is dropped. An absolute, home or relative path (the relative one
    with a slash and an extension on its last segment) is "file <name> in
    <parent>" when the last segment has an extension (a dot and 1 to 5
    alphanumerics), else "folder <name> in <parent>"; a trailing slash means
    folder, "." is "dot", "-" and "_" a space, `tmp` at the root "temp", `~`
    "home"; a URL is no path. Paths go first, then date-times, times and the
    remaining digits and hashes. Rejected for paths: every segment with
    "slash", the file name only, mapping to known repositories, not speaking
    paths.
 61. **Agent states** (operator 2026-11-10, decisions 61 to 64): the hub
    derives six states per agent session: sleeping (drain or suspend part,
    idle),
    suspending (drain or suspend part, still busy), working (process alive,
    busy), alive (process alive, idle), dead (process gone while a claim or
    task still names it) and unreachable (busy without an update for 15
    minutes, or a call without a receipt for 10 minutes). Inputs: the Claude
    Code session files (status, pid and its start tick), the night state and
    the radio receipts; a runtime without a session file shows alive or dead
    by its claim heartbeat. The hub's container sees neither the session
    files nor the host's processes, so a host timer
    (`kvb-orchestrator-sessions.timer`, every 15 seconds while the page
    polls) writes a snapshot with each process checked into the hub's
    state; one older than 5 minutes counts as absent. Rejected: an agent
    hook reporting its own state (a hook and a reinstall on every agent),
    the claim heartbeat alone (no working versus alive), the host's PID
    namespace or `/proc` in the container (every process's command line in
    reach of the web-facing hub).
 62. **State symbol**: an animated Bootstrap icon from the vendored sprite
    next to every agent in Orbit, Chord, Swimlane, Tree and 3D and in the
    agent panel; `prefers-reduced-motion` stops the animation. Rejected:
    emoji (font-dependent), a colored ring only (six states hard to tell
    apart).
 63. **Status menu**: a "Status" menu in the Agents toolbar holds one checkbox
    per state and "Faces in 3D", stored per browser like the saved views,
    no passkey. Rejected: hub-wide settings with a signature.
 64. **3D faces**: agent nodes in the 3D view show their face, on by default
    and switchable; repositories and branches stay spheres.
 65. **Day/Night per agent** (operator 2026-11-10, decisions 65 and 66): the
    Day/Night menu lists "All" and one checkbox per claimed agent. All ticked
    runs the global drain, suspend or resume as before; a subset runs it only
    for the ticked sessions (`night.py --target`), the passkey signs the
    board item with those sessions, and the radio call reaches only them.
    Rejected: a second menu for single agents.
 66. **Agent panel Day/Night**: every agent panel shows the agent's part and,
    for a claimed agent, Drain, Suspend and Resume for that agent alone, by
    day too. Rejected: single-agent parts only during a night.

 ## Acceptance Criteria
 ### Radio model
 - [x] `radio.py send` accepts exactly `call`, `broadcast`, `pan-pan`,
      `mayday`, `security` and the alias `direct`; `post`, `newsletter` and
      any other class exit 2.
 - [x] `radio.py post --to X` stores `post`; `radio.py post` without `--to`
      stores `newsletter`.
 - [x] `call` and `send direct` require `--to`; `broadcast`, `pan-pan`,
      `mayday` and `security` exit 2 with `--to`.
 - [x] `send direct --wake` is stored as `call`, `send direct` as `post`.
 - [x] New rows carry a version mark; rows without it are read as before:
      `direct` as `post` (as `call` when it woke), `broadcast` as
      `newsletter`.
 - [x] The UserPromptSubmit hook (`radio.py hook`) and the PostToolBatch hook
      (`radio.py tool`) never print a `post` or `newsletter` row.
 - [x] A new Stop hook `radio.py mailbox`, registered in
      `scripts/enable-plugins.js`, prints the unseen `post` and `newsletter`
      rows of the session at most 10 at a time with a "N more" line, marks
      them seen and exits 2; with nothing unseen it exits 0 and prints
      nothing.
 - [x] `radio.py listen` wakes an idle session only for `call`, `broadcast`,
      `pan-pan`, `mayday` and `security`, never for `post` or `newsletter`.
 - [x] `radio.py tool` delivers `call` (to its addressee), `broadcast`,
      `pan-pan`, `mayday` and `security` at the next tool step.
 - [x] When a call reaches the callee's context, a receipt row (callee, call
      time, read time) is stored; the caller's mailbox shows
      "CALL <to> read <time>". The receipt never wakes the caller.
 - [x] While `radio-silence.json` holds an active mayday, a PreToolUse hook
      (matcher `Edit|Write|MultiEdit|NotebookEdit|Bash`) exits 2 for Edit,
      Write, MultiEdit and NotebookEdit and for every Bash command that
      matches neither the config's `never_block` nor its new `mayday_allow`
      regexes nor a plain call of `radio.py`.
 - [x] The mayday's sender passes; `radio.py assist` adds the caller to the
      mayday's helpers, who pass too, and the mayday line names them.
 - [x] After `radio.py clear` the same calls pass again.
 - [x] `skills/kvb-org-radio/SKILL.md` separates the radio (`send`,
      immediate) and the post (`post`, delayed), each class with when to use
      it and how it is delivered; post is the default; markdownlint stays
      green.
 ### Organisation update
 - [x] A skill `kvb-org-update` with `scripts/update.py` exists.
 - [x] `update.py --repo <skills repo> --dry-run` prints every skill whose
      files changed between the last announced revision (kept in the council
      directory) and `HEAD`, with the subjects of the commits that touched it.
 - [x] Without `--dry-run` it sends one `newsletter` through `radio.py post`
      that names each changed skill and tells every agent to re-read its
      `SKILL.md` before the next use, then records `HEAD` as announced; a
      second run without new commits sends nothing.
 - [ ] The radio change of phase 1 is announced through it.
      Obsolete (operator 2026-11-12): a past event no record proves any more.
 ### Orchestrator surface and rename
 - [x] The page title and heading read "Agent Orchestrator".
 - [x] `grep -rnE 'kvb-hub|kvb_hub|KVB_HUB'` over the repository finds only the
      migration code and its tests.
 - [x] The install migrates `~/.local/share/kvb-hub`, `~/.config/kvb-hub`,
      `~/.local/state/kvb-hub-approvals`, the `kvb-hub` MCP registration, the
      settings hook entries, the systemd unit and the container to the
      `kvb-orchestrator` names. A second run changes nothing (scratch-HOME
      test).
 - [ ] The navigation has exactly three top-level entries Stream, Agents and
      Artifacts; Stream has the sub-items Inbox and Firewall.
      Obsolete: decision 23 adds Tasks, 003 decision 2 removes Inbox.
 - [x] Every agent appears once under its current name: a register worker
      such as "Stage (this session)" or "infinito-nexus-core-c8 (Production)"
      maps to the agent named before the bracket.
 - [x] The keys 1 to 3 switch the top-level entries.
 - [x] The hashes `#stream`, `#stream/inbox`, `#stream/rules`,
      `#agents/<view>` and `#artifacts/<view>` route; `#graph…` and `#tree`
      redirect to their successors.
 - [x] Agents and Artifacts show a switch with Orbit, Chord, Swimlane, Tree and
      3D in this order, and each view has its own hash.
 - [ ] The header holds exactly the title, the ⌘K button and the ⚙ button.
      Obsolete: decision 59 adds Radio, 003 decision 17 the bubbles switch.
 - [x] Badges:
  - [x] Inbox shows the waiting items that are not snoozed.
  - [x] Agents shows the agents with a heartbeat in the last 900 s.
  - [x] Artifacts shows the runner jobs that are queued or running.
  - [x] A badge at 0 is hidden.
 - [ ] A red Mayday banner with "cancel" exists if and only if a mayday is
      active; "cancel" runs `radio.py clear`.
 - [ ] The Agents toolbar holds:
  - [ ] Radio to all, with the class choice Newsletter, Broadcast, Pan-Pan,
        Security, Mayday and Newsletter preselected.
  - [ ] Cancel mayday, Priority and Day/Night.
  Obsolete: decisions 52 and 59 move the composer and Cancel mayday into
  the header radio spot; Priority and Day/Night ship.
 - [x] The agent panel sends with the choice Post (preselected) or Call.
 - [x] ⚙ "Ambience" holds Sky, Music, Control room and Notifications;
      ⌘K lists every former header tool.
 - [x] The Stream shows exactly four category chips For you, Radio, Work and
      Transcripts, and one search line that filters by `agent:`, `kind:` and
      `since:`.
 - [ ] "Filter ▾" holds the kind sub-filters, the transcript parts, the saved
      views and the custom range.
 - [x] The time control reads "24 h ▾" and holds the replay.
 - [x] Transcripts are off by default.
 - [x] The Inbox renders in the main area under `#stream/inbox`; the right
      rail `#rail` no longer exists, at any width.
 - [x] The read-aloud class choice lists exactly the seven classes of
      decision 3; Mayday stays checked and locked.
 ### pkgmgr branch tree
 - [x] The kvb-think-dialectic result on the data path is recorded in the
      phase 3 commit body before any code of phase 3 is written.
 - [x] `pkgmgr branch tree --format json` prints, for every repository pkgmgr
      knows and every worktree under `<repo>/.worktrees` and
      `~/.local/share/worktrees`, these fields:
  - [x] the repository's path, remote and default branch;
  - [x] per branch: upstream, ahead, behind and gone;
  - [x] per worktree: path, HEAD and its state, one of `clean`, `changed` or
        `missing`;
  - [x] detached worktrees, and `generated_at`.
 - [x] It lists every repository `pkgmgr list` names, also one without extra
      branches or worktrees.
 - [x] Per branch and worktree it carries the gc state (`merged-clean`,
      `unmerged`, `dirty`, `protected`, `stale`), what merged it (ancestor,
      `pr#N`, `line:X`), the counts of staged, unstaged and untracked files,
      ahead, behind, gone, locked and the gc skip reason.
 - [x] Tree and gc share one classification function; on a fixture
      `pkgmgr branch tree --format json` and `pkgmgr branch gc --json` agree
      on every item's state.
 - [x] Forge facts (open and merged pull requests) are fetched at most once
      per 10 min per repository, only with a token from the Secret Service;
      without one the file says `forge: unavailable` and "merged by" falls
      back to ancestor and line.
 - [x] `delete_ready` is true only while the token resolves through the
      Secret Service, which the scan never unlocks; otherwise it is false
      with the reason.
 - [x] `--format yaml` prints the same data.
 - [x] `--output FILE` writes it atomically.
 - [x] The scan starts no hook, filter, fsmonitor, pager or external diff of a
      scanned repository and never lazy-fetches (fixture test with a planted
      `core.fsmonitor`).
 - [x] `pkgmgr branch open|close|drop|gc` rewrite the file when it exists.
 - [x] The orchestrator install enables a systemd user timer that writes it
      60 s after its previous run ended while the page polled within the
      last 5 min, on at most half a core, with pkgmgr built from the newest
      signed tag.
 - [x] The orchestrator mounts the file read-only and reads only it.
 - [x] `orchestrator/kvb_orchestrator/tree.py`'s git scan is gone and no
      module of the orchestrator starts `git`.
 ### Agents and Artifacts views
 - [x] Artifacts:
  - [x] Orbit, Chord, Swimlane and Tree draw what decision 16 names, from the
        pkgmgr tree file.
  - [x] Register artefacts (images, volumes, logs) appear as leaves of their
        task or worktree.
 - [x] Agents:
  - [x] Orbit, Chord and Swimlane keep today's content.
  - [x] Tree shows the operator → chair → sessions → subagents spawn tree
        with running and finished states.
 - [x] 3D in both tabs runs on the vendored `3d-force-graph` 1.80.1 and
      `three` 0.186.1, with their MIT licence texts beside them and no CDN
      request (CSP unchanged).
 - [x] 3D offers the layouts Force, Time and Spawn depth.
 - [x] A click on a 3D node opens the same panel as in 2D.
 - [x] 3D respects `prefers-reduced-motion`.
 ### Delete merged branches
 - [ ] The Artifacts Tree marks every branch and worktree with icons for
      merged (with what merged it), clean, uncommitted changes (with counts),
      unpushed commits, gone upstream, locked, stale and protected.
 - [x] A `merged-clean` item without a gc skip reason shows a delete button,
      and the Tree header shows "Delete all merged"; both are disabled,
      with the reason as tooltip, while `delete_ready` is false.
 - [x] A click shows the gc dry-run lines of exactly the chosen items;
      "Delete" requires the operator signature through `/api/sign`.
 - [x] The orchestrator writes the signed job (repository, branch, worktree
      and tip sha per item, no command) into a host-mounted job directory and
      holds no git, token or key.
 - [ ] A systemd user path unit verifies the signature on the host and runs
      `pkgmgr branch cleanup --apply --local` for exactly the signed items,
      matched exactly, never as a pattern; `--local` removes the worktree, the local
      branch, the compose stack without `-v` and its images, never a remote
      branch, and needs no SSH key.
 - [x] The unit refuses, and changes nothing for, an item whose tip or state
      differs from the signed one, an unknown repository, a non-`merged-clean`
      item and a job with a bad or missing signature, and reports why.
 - [x] The unit writes each item's result back and rewrites the tree file; the
      Tree shows the result.
 ### Icons
 - [x] Bootstrap Icons 1.13.1 is vendored once as an SVG sprite with its MIT
      licence text beside it; no page loads it from a CDN.
 - [x] The navigation, the header, the view switches, the toolbars, the
      Stream chips and the Inbox actions of the orchestrator show icons
      instead of text labels.
 - [ ] The review pages and the meditation page show icons instead of text
      labels on their buttons.
 - [x] Every icon element has a `title` and an `aria-label` that carry the
      former text (DOM test over every page).
 ### Phase 5: inbox, UI, Hierarchy, Tasks
 - [x] A deny is refused by the hub unless its passkey proof verifies; the
      PermissionRequest hook quotes a deny reason only when it verifies.
 - [x] A rule, also one an agent requested, is stored only with a passkey
      assertion the hub verified against the pinned keys.
 - [x] `operator_message(id, text, to)` answers `match` only for a verified
      proof whose signed text and recipient equal the arguments.
 - [x] The offices unit and the runner stay off while the installed
      `council.py`, `nofollow.py` or `rasci.py` differ from the tree.
 - [x] `rasci.py agents order` writes only `agent-order.json` and no `--prio`.
 - [x] W1 to W4 are merged into master, each commit with its score block.
 ### Phase 6: English and radio speech (S0)
 - [x] The text handed to the speech engine for a `security` row starts with
      "say-cure-ee-tay" three times; the page shows "Sécurité".
 - [x] `8e180be` is spoken "eight echo one eight zero bravo echo" and
      `42305` "four two tree zero fife" (unit test on the pronunciation step);
      the displayed line is unchanged.
 - [x] A scan of the tree finds no German UI, message or document text
      outside quoted trigger phrases (test with an allowlist of those
      phrases).
 ### Phase 6: fixes (S1)
 - [x] `#agents/orbit` at 1920, 1366 and 390 px has
      `document.documentElement.scrollHeight <= innerHeight` (e2e probe).
 - [x] Two state builds with the same claims add no second rename event to
      the Stream (unit test on the timeline).
 - [x] The Deutschlandfunk AAC stream plays in Chromium and Firefox through
      the radio (e2e with a recorded fixture of its redirect chain) and the
      root cause is named in the commit message.
 - [x] With squelch at 0 no beep plays, music on or off (unit test on the
      audio scheduler).
 - [x] Without a tree file the Tree names the missing `pkgmgr branch tree`
      and the release step.
 ### Phase 6: popups and search (S2)
 - [x] A click on an agent opens the popup with a fade; Escape and a click
      outside close it; the Details side panel no longer exists.
 - [x] A click on a node enlarges it, marks it red and draws a leader line to
      a translucent popup; a second click elsewhere restores the node.
 - [x] A search field with suggestions replaces the node chip list; no view
      renders more than one chip per search hit.
 ### Phase 6: faces (S3)
 - [x] The face generator yields at least 1000 distinct attribute
      combinations and the same face for the same agent id (unit test).
 - [x] A speaking agent's face animates its mouth; a silent one does not
      (DOM test on the class while the radio plays).
 ### Phase 6: night commands (S4)
 - [x] `kvb-org-drain`, `kvb-org-suspend`, `kvb-org-resume`,
      `kvb-agent-drain`, `kvb-agent-suspend` and `kvb-agent-resume` exist;
      the old six names exist nowhere in the tree except in the migration
      and `kvb-skill-cleanup` history (grep test).
 - [x] The Controls menu shows Drain, Suspend and Resume and each needs the
      passkey, like the board actions today.
 ### Phase 6: Tasks with asks and choices (S5)
 - [x] Every pending ask, rule request, operator row and choice card shows in
      the Tasks tab under "waits on Operator"; no Choices column exists.
 - [x] Each channel button sends the fixed choice request with no text field;
      `post` and `call` take a multi-select of agents.
 - [x] A click on a choice option sends a passkey-signed answer the agent can
      check with `operator_message`.
 ### Phase 6: Firewall (S6)
 - [ ] The tab is called Firewall and lists hub rules, allow and deny
      patterns and the settings permissions, grouped by tool and prefix as
      read from the settings files.
 - [ ] A rule or rule set applies to one agent, a named group or all agents.
 - [ ] A settings change is written only by the host executor after the
      passkey check, only to a listed file, with a backup beside it; a forged,
      replayed or unlisted-file job changes nothing (unit tests).
 ### Phase 6: Resources (S7)
 Replaced by [003 W4 Resources](003-operator-workbench.md#w4-resources).
 - [ ] The tab shows tokens per agent and accumulated, and CPU, RAM, disk and
      load, on the shared time axis, several values per chart.
 - [ ] Token counts equal the sum of the transcript usage fields of a fixture
      (unit test); host samples come from the host unit's file, not from the
      container.
 ### Phase 6: shared cache (S8)
 - [ ] With `INFINITO_ARTEFACT_BASE` set, every `ADD` and clone of the image
      build uses `<base>/<host>/<path>` and the unchanged sha256 pins; unset,
      the build uses the upstream URLs (test over the rendered Dockerfile).
 - [ ] With a configured `svc-ai-speech` URL the hub sends STT and TTS there;
      without it the in-container engines answer (unit test with a stub).
 - [ ] `make orchestrator-install` succeeds in a scratch HOME without any core
      stack.
 ### Phase 6: Gantt, estimates, burndown and burnup (S5)
 - [x] `rasci.py set <task> --after <other>` stores the dependency and
      `--drop-after <other>` removes it; an unknown task and a cycle are
      refused.
 - [x] The Gantt view draws one bar per task from start to end, a running
      task to now, and one arrow per explicit, branch-base and queue-order
      edge of a fixture register and queue.
 - [x] The forecast selector offers `always` (default), `points only` and
      `real only`; a hatched bar is as long as the median duration of done
      tasks (no estimate) or points times median hours per point (story
      points).
 - [x] The estimation toggle defaults to `No estimate`, is stored in the hub
      settings and survives a reload.
 - [x] Burndown and burnup offer the scopes whole register (default), list
      filter within the time window, and one agent or line; with no estimate
      they count tasks, with story points they sum complexity and draw the
      unestimated tasks as a line of their own.
 - [x] "Request estimates" shows only in story points mode; a click or
      `/kvb-org-queue-estimate` sends exactly one newsletter to all agents
      that lists every unestimated task with every party holding a RASCI
      role in it; a state build or a mode switch sends none.
 - [x] A per-task or bulk business value change is stored only with a
      verified passkey assertion over the exact task ids and values; a
      forged, replayed or altered batch changes nothing, and WSJF uses the
      operator value instead of the median.
 - [x] The task list sorts by each mode of decision 50 in both directions.
 ### Phase 6: radio spot, compact menus, trend, ETA, Tasks 3D (S5.1)
 - [x] The toolbar radio button expands inline and sends a post, a call to
      chosen agents and each to-all class, Record included; the Radio tab
      shows no composer.
 - [x] The radio gear holds the tones, squelch and read-aloud settings, the
      general settings no longer do, and a changed value survives a reload.
 - [x] Cancel mayday sits in the expanded radio spot and no longer in the
      toolbar; it still needs its confirmation.
 - [x] The Day/Night menu shows only the badge and three buttons; hovering
      each shows its explanation.
 - [x] The Tasks toolbar is one row at 1920 and 1366 px; "Request choices" is
      a dropdown sending the same signed choice requests as before.
 - [x] The trend selector offers off (default), linear regression and
      velocity over N days; the line and the forecast date match the
      fixture's computed values, and the choice survives a reload.
 - [x] Hovering a burn chart point lists exactly the fixture work packages of
      that step.
 - [x] Every list row shows an ETA, which equals the end for done tasks and
      start or now plus the forecast length otherwise, in both estimation
      modes.
 - [x] The Tasks 3D view draws one node per task and one edge per dependency
      of the fixture, in Force and Time layouts.
 - [x] Two state refreshes after a manual camera move leave the 3D camera
      where the operator put it.
 ### Phase 6: radio in the header (S5.4)
 - [x] The header shows Radio, Commands and Settings as icon buttons; Radio
      opens the spot above the main area on Stream, Inbox, Agents, Artifacts
      and Tasks, and closes it again.
 - [x] No Radio tab, no "Send …" button and no radio button in the Agents
      toolbar remain; `#stream/radio` lands on `#stream` with the spot open
      and the message field focused.
 - [x] Cancel mayday shows only its icon, keeps its tooltip, its confirmation
      and its passkey signature.
 - [ ] The spot shows the speaking caption, the last five sent messages and
      the stations with play and stop.
 ### Phase 6: agent states and 3D faces (S5.3)
 - [x] The state of every fixture session matches decision 61 for each of the
      six states and for a session without a session file (unit test).
 - [x] Orbit, Chord, Swimlane, Tree, 3D and the agent panel show the state
      symbol of each fixture agent.
 - [x] Unticking a state in the Status menu hides its symbols in every view;
      the choice survives a reload.
 - [x] The 3D view shows agent faces by default and spheres after unticking
      "Faces in 3D".
 - [ ] `make orchestrator-install` enables `kvb-orchestrator-sessions.timer`,
      and `make orchestrator-check` reports it active.
 ### Phase 6: Day/Night per agent (S5.2)
 - [x] `night.py drain|suspend|resume --target=<id>` sets and lifts one
      session's part by day and during a mode, and `night.py status` prints
      it as the `you:` line (`tests/test_night.py`).
 - [x] The Day/Night menu lists "All" and one checkbox per claimed agent; all
      ticked sends the unchanged board item, a subset signs and runs only for
      the ticked sessions, and none ticked disables the three buttons.
 - [x] A proof for one set of agents is refused for another set and for all,
      and an unclaimed session is refused before anything runs
      (`tests/test_hub_board.py`).
 - [x] Every agent panel shows the agent's part and Drain, Suspend and Resume
      for that agent alone.
 ### Tests
 - **Unit**
  - [x] Radio: class mapping, `--to` rules, the mailbox Stop hook, the
        receipt and the mayday block hook, each red before and green after.
  - [x] Organisation update on a fixture repository: changed skills with
        their subjects, nothing new sends nothing.
  - [x] pkgmgr branch tree on fixture repositories: ahead, behind, gone,
        detached and missing worktree, JSON and YAML, the planted fsmonitor,
        staged, unstaged and untracked counts, tree and gc states agreeing.
  - [x] Delete job: a bad signature, a changed tip, a non-`merged-clean`
        item and a branch name with pattern characters are each refused.
  - [x] Orchestrator: the scratch-HOME migration, routing including old
        hashes, badge counts.
  - [ ] Phase 6: pronunciation (Sécurité, NATO hashes, ICAO digits),
        rename-once timeline, squelch scheduler, face generator, settings
        writer (forged, replayed, unlisted file), token sums, German text
        scan.
  - [x] S5 Gantt and estimates: dependency edges and cycle refusal, forecast lengths, burn
        sums per mode and scope, newsletter body and its single send, bulk
        business value signature (forged, replayed, altered), sort orders.
  - [x] S5.1: regression and velocity trend with their forecast dates, point
        tooltips, ETA in both modes, radio settings stored from the gear.
  - [x] S5.4: the navigation without the Radio tab, `#stream/radio`
        redirecting to `#stream` with the spot flag.
  - [x] S5.5: ICAO digit words, Zulu times, DTG with offset conversion,
        dates, decimals and spoken paths.
  - [x] S5.3: each agent state from a fixture snapshot, night state and
        receipts, a session without a record; the host client's snapshot
        from fixture session files with a reused pid; a stale or malformed
        snapshot read as absent.
  - [x] S5.2: night.py targets by day and during a mode, the signed board
        item with agents (forged set, unclaimed session), the parts in the
        state.
 - **Integration**
  - [x] Two scratch sessions exchange `post` and `call` through the real hook
        entry points (JSON on stdin): the post appears only on the callee's
        Stop and the call at its next tool step with a receipt to the caller.
  - [x] A mayday blocks an Edit until `clear`.
  - [ ] The orchestrator's `/api/tree` serves a pkgmgr-written file.
  - [ ] On a fixture repository with a file remote and a test token source, a
        signed job through the path unit removes the merged worktree, the
        local and the remote branch, and the rewritten tree no longer lists
        them. Obsolete: contradicts decision 21; 003 decision 10 replaces it.
  - [ ] `make test` green on the HEAD that carries every phase (operator
        2026-11-12).
 - **E2E**
  - [x] A headless Chromium and Firefox run opens Stream, Inbox, Firewall and
        every view of Agents and Artifacts at 1920, 1366 and 390 px wide and
        saves the screenshots shown at each operator checkpoint.
  - [x] It sends a Call from the agent panel and sees its receipt in the
        Stream.
  - [x] On fixture data it shows the state icons in the Artifacts Tree and
        runs the delete flow: dry-run dialog, signature, result.
  - [ ] Phase 6: no page scrollbar on any view, agent and node popups,
        choice request and signed answer, Firewall settings diff and
        signature, Resources charts, each at 1920, 1366 and 390 px.
  - [x] S5: Gantt with arrows, burndown and burnup, the estimation toggle,
        "Request estimates" and a signed bulk business value change, each at
        1920, 1366 and 390 px.
  - [x] S5.1: radio spot (send, gear, cancel mayday), Day/Night tooltips,
        one-row Tasks toolbar, trend and point tooltips, ETA column, Tasks
        3D and a steady 3D camera, each at 1920, 1366 and 390 px.
  - [ ] S5.4: the header radio button opens the spot on every tab, every
        class sends from it, the icon-only Cancel mayday, the speaking
        caption and the stations inside the spot, in Chromium and Firefox at
        1920, 1366 and 390 px.
  - [x] S5.3: state symbols in every Agents view and the panel, the Status
        menu toggles through a reload, 3D faces on and off, in Chromium and
        Firefox at 1920, 1366 and 390 px.
  - [x] S5.2: agent checkboxes in the Day/Night menu and the agent panel's
        buttons, signed in Chromium and refused unsigned in Firefox, each at
        1920, 1366 and 390 px.

 # 002 - Cosmos
 ## User Story
 As the operator and the designer, I want the orchestrator's sky, music and
 orbit scene as one reusable component behind a small live globe, so that the
 orchestrator and every Infinito.Nexus web app can show the same calm
 background without carrying its code twice.
 ## Decisions (operator-confirmed 2026-11-06; do not re-litigate)
 1. **Scope**: everything of the orchestrator's background moves: the sky (sun,
   moon, stars, twilight stages, day and night palettes with contrast check),
   the generated meditative music and the orbit and 3D scene. The radio
   streams with their schedule stay in the orchestrator. Rejected: the sky
   only.
 2. **Repository**: `github.com/kevinveenbirkenbach/cosmos`, not managed by
   pkgmgr, laid out as an Infinito.Nexus custom role `web-app-cst-cosmos` that
   core pulls from its inventory-declared source. Rejected: the infinito-nexus
   organisation, a pkgmgr-managed release.
 3. **Form**: Web Components (`<cosmos-ambience>` for sky and music,
   `<cosmos-graph>` for the 3D scene) that also set `--cosmos-*` CSS custom
   properties every design can follow; a "colors only" mode draws nothing.
   Rejected: a plain ES module.
 4. **Globe menu**: a small globe logo turns with the Earth's real rotation and
   shows the current Earth with its live day and night line; a click on it
   reveals every control, nothing else is visible while it is closed.
   Rejected: a visibly spinning globe (not the real orientation).
 5. **Licence**: MIT, like the skills repository it comes from. Rejected: the
   Infinito.Nexus Community License (non-commercial, limits reuse).
 6. **Work split**: Skills extracts the code into cosmos and switches the
   orchestrator to a pinned cosmos version; the IAM agent builds the core
   integration: a role that the design service `web-svc-design` activates.
   Rejected: IAM doing everything.
 7. **Timing**: implemented after requirement 001; the core part also needs
   core's custom roles (requirement 046) on core main. Rejected: starting now.
 8. **Icons**: the controls use Bootstrap Icons per decision 19 of
   requirement 001.

 ## Acceptance Criteria
 ### Repository
 - [ ] `github.com/kevinveenbirkenbach/cosmos` holds an MIT `LICENSE`.
 - [ ] `pkgmgr list` does not list cosmos.
 - [ ] The repository is a role named `web-app-cst-cosmos`: `README.md`,
      `meta/` (main, info, services, license), `tasks/main.yml`, and the
      components under `files/`.
 - [ ] An inventory group `web-app-cst-cosmos` with `custom: true` and a
      pinned source makes core's `make roles-pull` place it.
 - [ ] Every core role lint passes on the placed role.
 ### Components
 - [ ] `<cosmos-ambience>` takes `latitude`, `longitude`, `mode`
      (`full` or `colors`) and `music` with a volume, and follows
      `prefers-reduced-motion`.
 - [ ] It sets `--cosmos-sky-top`, `--cosmos-sky-bottom`, `--cosmos-stage` and
      `--cosmos-text` and updates them at least once a minute.
 - [ ] Text against sky keeps a contrast of at least 4.5:1 at every minute of a
      day at 0° N 0° W and at 52.5° N 13.4° E (unit test).
 - [ ] Sun and moon positions match published reference values within 1° for
      at least six fixed dates (unit test).
 - [ ] `<cosmos-graph>` renders the 3D scene on vendored `3d-force-graph`
      1.80.1 and `three` 0.186.1 and takes nodes and links as data.
 - [ ] The generated meditative music plays with a volume; no radio stream
      code is in the repository.
 ### Globe menu
 - [ ] A globe of at most 48 px shows a public-domain Earth texture with the
      live day and night line, turned to the Earth's current rotation.
 - [ ] A click, Enter or Space opens the control panel and Esc closes it.
 - [ ] While the panel is closed only the globe is visible.
 - [ ] Every control is a Bootstrap Icon with `title` and `aria-label`.
 ### Orchestrator
 - [ ] The orchestrator vendors a pinned cosmos tag and loads it under its
      nonce CSP.
 - [ ] `ambience.js`, the sky code and the generated music are gone from the
      orchestrator; its radio-stream schedule stays.
 - [ ] The orchestrator's 3D views render through `<cosmos-graph>`.
 ### Core (IAM)
 - [ ] IAM writes the core requirement for the integration.
 - [ ] With `web-svc-design` activating cosmos, a designed web app shows the
      cosmos background behind its content with the globe.
 - [ ] With it off, the app loads no cosmos file.
 ### Tests
 - **Unit**
  - [ ] Astronomy against reference values.
  - [ ] Palette contrast over a day.
  - [ ] Attribute parsing.
  - [ ] Globe orientation at fixed times.
 - **Integration**
  - [ ] Core's `make roles-pull` places cosmos and its role lints pass.
  - [ ] The orchestrator serves the pinned cosmos under its CSP.
 - **E2E**
  - [ ] Headless Chromium and Firefox open the cosmos demo page and the
        orchestrator at noon, dusk and night with the menu closed and open,
        and save the screenshots.
  - [ ] One designed core app is opened with cosmos on and off.

 # 003 - Operator Workbench
 ## User Story
 As the operator of many parallel agents, I want to handle every open task,
 review, plan, branch gate and resource figure from one simple, interactive
 Agent Orchestrator, and agents that commit through fast deterministic hooks
 instead of skipping them, so that I steer the work by drag and drop, see what
 changed and what it costs, and a gate means something again.
 ## Decisions (operator-confirmed 2026-11-11; do not re-litigate)
 1. **One document**: the whole package lives here as work packages W1 to W6.
   Rejected: one document per feature.
 2. **Operator tasks next to Tasks**: the Inbox entry leaves the top navigation
   and the Stream; the Tasks entry carries the count of open operator tasks;
   the Tasks filter "Waits on Operator" shows them as Stream cards with
   checkboxes and the bulk bar. The Stream keeps its operator cards with their
   actions. Rejected: a separate Operator tab, a Stream without operator rows.
 3. **Diff preview**: every review card shows its diff expanded; the requesting
   agent's script ships it with the review (the hub reads no git, 001); one
   block per file, a file over 400 changed lines collapsed, 2 MiB cap with the
   rest listed by stat; a file whose old or new content holds an armour
   line or matches a MEDUSA secret rule (every file when no rule loads)
   ships only path, status, mode and counts with the note "content withheld".
   Rejected: the hub reads git.
   Every Ask for a `git commit` shows the staged diff the same way (with
   `-a` or `--all` the diff against HEAD); the permission hook on the host
   attaches it (operator order 2026-11-11).
 4. **Inline feedback**: selected lines of a diff or a command go back to the
   agent as one radio `post` with path, line range, quote and text, through
   the right-click menu, the key `f` or a button at the selection.
 5. **Kanban**: columns Waiting, Running and Done; Blocked and Stopped become
   labels; `operator/*` rows stay off the board; swimlanes P1, P2, P3, P4+ and
   Unpinned (by WSJF), collapsible; Done older than 24 h hidden by default.
 6. **Lines**: solid arrows are `after` dependencies, several into one card; one
   dashed line runs through the cards holding a live queue entry, in queue
   order. Rejected: rank lines per lane, dependencies only.
 7. **Drag and drop**: card to column = status, to lane = priority pin, handle
   onto a card = `after`; a click on an arrow removes it; a click on a card
   opens its popup. Moves are staged, shown at once and applied with one
   passkey; each affected agent gets a post. Rejected: a passkey per move, no
   passkey.
 8. **Dependencies are enforced**: the queue holds a task until its `after`
   tasks are done, and the rank follows them. Rejected: display only, warning
   only.
 9. **Forecast**: two lines in distinct colours, the finish at fixed scope and
   the finish at growing scope (done trend meets scope trend); ∞ when never
   reached. Scope excludes `operator/*`; a task unchanged for 3 days is
   labelled stale and counted apart. Rejected: count everything, only drop
   operator rows.
 10. **Clean all merged**: dry run, one passkey, signed job. Local branches
    merged by ancestry and without a remote branch need no token; remote
    branches and squash-merge candidates need the GitHub token, stored through
    an operator row. Rejected: wait for the token, ancestry for remotes.
 11. **Ancestry**: Artifacts and Agents get a family tree (generations top down)
    in the slot of today's Tree view. A branch may have several parents;
    parents are recorded at creation (post-checkout hook), older branches are
    derived and marked derived, and the operator corrects them by drag and
    drop. Rejected: derivation only, manual only.
 12. **Gates**: a level (none < quick < test < quality-high < e2e) per branch
    and action (commit, merge, push, pr), inherited from all ancestors, the
    strictest wins, an own rule wins over all; kept in the local database
    `~/.local/state/agents-council/gates.db` (the council root lives in the
    tmpfs `/tmp` and loses it at reboot) that agents read through `gates.py`;
    set in every Artifacts view. Rejected: a committed `.gates.yml`, repo plus
    local.
 13. **Hooks with receipts**: pre-commit runs only quick checks of the staged
    files (< 30 s); heavy gates run through the queue and on green write a
    receipt (tree sha of the tested content, level, log); commit-msg,
    pre-merge-commit and pre-push only compare the receipt with the resolved
    level (< 1 s). `--no-verify` only on the operator's word for that commit.
    Core's hooks change only in a core PR agreed with Experiment and Main.
    Rejected: heavy gates at pre-push, skills-side checks with `--no-verify`.
 14. **Resources**: a host unit samples every 60 s without any LLM call: disks
    per mount, CPU, RAM, swap, load, GPU and VRAM (`nvidia-smi` only while the
    dGPU is awake, else asleep), the queue; tokens per agent and model from
    the transcripts' usage fields. 7 days at 1 min, 90 days at 15 min.
    Replaces 001 S7.
 15. **Simplicity**: icons, counts and names instead of text; every action is
    reachable in the GUI.
 16. **Delivery**: one subtree `feature/operator-workbench` with split
    worktrees, at most 4 subagents at a time on W1 to W4 and W6, W5 serially
    in the requesting agent with Experiment; one gate (make test, e2e Chromium
    and Firefox at 1920, 1366 and 390 px, MEDUSA, 90/5); master only on the
    operator's word. Rejected: 8 in parallel, serial without subagents.
 17. **Speech bubbles**: one toolbar icon switches speech bubbles on in every
    view that shows agents. The agent being read aloud gets the largest
    bubble, its words appear one by one in time with the audio; when it ends
    the bubble fades while the next one grows and is read. Waiting messages
    show a small `…` bubble, the newest smallest, steps in between. Without
    TTS the bubbles run at reading pace. Font: vendored Comic Neue (SIL OFL
    1.1). Rejected: a ticker, the full text with a karaoke mark, bubbles only
    with audio, system fonts only, a switch only in the settings, a caption
    under the speaker only.

 ## Acceptance Criteria
 ### W1 Operator tasks
 - [x] The top navigation has no Inbox entry; the Tasks entry shows the count of
      waiting, unsnoozed operator tasks, hidden at 0.
 - [x] The Stream has no inbox button; `#stream/inbox` opens `#tasks/operator`.
 - [x] `#tasks/operator` shows each operator task as a Stream card (command,
      directory, reason, run, deny, copy, snooze, pin) with a checkbox; the
      bulk bar acts on the checked cards.
 - [x] The Stream keeps its operator cards with their actions.
 - [x] The bulk approve counts and approves every checked card, asks, reviews
      and operator commands alike, with one passkey.
 - [x] Approving or denying an Ask in the hub also settles the agent's native
      permission dialog where the runtime allows it (the permission hook
      waits for the hub's decision); where it does not, the limit is recorded
      here.
      Limit: Claude Code runs the PermissionRequest hook before it shows its
      own dialog, so a hub decision within the hook's `--timeout` settles the
      ask and no native dialog appears. After the timeout, with the hub down
      or an answer whose signature does not verify, the hook answers nothing
      and Claude Code shows its own dialog, which a later hub decision no
      longer settles. `make orchestrator-hook` installs the hook for Claude
      Code only; other runtimes keep their native prompt and post no ask.
 - [x] A review card shows its diff expanded: one unified block per file,
      additions and deletions coloured, a file over 400 changed lines
      collapsed, a binary file named only.
 - [x] The review request of `approval.py` (kvb-git-diff) carries
      `git diff --cached` of the exact staged tree; past 2 MiB the rest is
      listed per file with its stat.
 - [x] An Ask for a `git commit` carries the staged diff of its working
      directory (with `-a` or `--all` the diff against HEAD), attached by
      `permission_hook.py`, and shows it like a review, feedback included.
 - [x] A file whose content holds an armour line or matches MEDUSA's secret
      rules, and every file when no rule loads, is shown by stat with the
      note "content withheld".
 - [x] An allow of a commit Ask is bound to the staged tree `git write-tree`
      prints (with `-a` also the working tree); a different tree at approval
      turns it into a deny "staged tree changed since the preview".
 - [ ] Selecting lines in a diff or a command and choosing Feedback (right-click
      menu, key `f`, or the button at the selection) posts one radio `post` to
      the requesting agent with path, line range, quote and text; the feedback
      shows under the card.
 ### W2 Kanban
 - [x] Columns Waiting, Running and Done; no Blocked or Stopped column.
 - [x] A blocked task carries a red Blocked label, a stopped one a grey Stopped
      label in Done; `operator/*` rows are not on the board.
 - [ ] Swimlanes P1, P2, P3, P4+ and Unpinned, collapsible, Unpinned sorted by
      WSJF rank; Done cards older than 24 h hidden until shown.
 - [ ] Each `after` dependency is a solid arrow into the dependent card, several
      per card allowed; the cards holding a live queue entry are joined by one
      dashed line in queue order.
 - [ ] Dragging a card to a column stages a status, to a lane a pin (P4+ the
      lowest free pin from 4, Unpinned none), its handle onto a card an
      `after`; a click on an arrow stages its removal; every move is also in
      the card's keyboard menu.
 - [ ] Staged moves show at once as pending; "Apply n changes" signs them with
      one passkey; the host executor applies them through `rasci.py`, refuses
      a cycle or a `done` with an open key result, and the card shows why.
 - [x] Each affected agent receives one post listing the operator's changes to
      its rows that `rasci.py` applied, once the whole signed batch ended.
 - [ ] A click on a card opens its detail popup.
 ### W2 Forecast
 - [ ] The burn chart draws, in distinct colours with a legend, the finish at
      fixed scope and the finish at growing scope, each ending at its date; a
      line never reached shows ∞.
 - [ ] Scope excludes `operator/*`; a task without a register change for 3 days
      carries a Stale label, is counted apart and can be stopped from the
      board.
 ### W3 Artifacts
 - [x] "Clean all merged" shows the gc dry run of every `merged-clean` item; one
      passkey runs the signed job.
 - [ ] Without a GitHub token, local branches merged by ancestry into the
      default branch and without a remote branch can be deleted; the others
      show "token needed", and an operator row stores the token.
 - [ ] Artifacts and Agents show Ancestry in the Tree slot: generations top
      down, several parents per node; a derived parent edge is dashed.
 - [ ] Dragging a branch onto another stages a parent edge, applied with the
      board's passkey batch.
 - [ ] Agents' Ancestry shows operator, chair, sessions and subagents.
 - [ ] Every Artifacts view shows each branch's effective gate level per action
      as an icon (inherited ones faint, source in the tooltip) and lets the
      operator set a rule, signed.
 ### W5 Gates, receipts and hooks
 - [x] `gates.py` keeps rules, parents and receipts in
      `~/.local/state/agents-council/gates.db`. Amended by Experiment's
      condition 3 below: rules and operator or derived parents live in
      `gates.db`; receipts and the parents the post-checkout hook records are
      written from the sandbox as rows of `gate-receipts.jsonl` and
      `gate-parents.jsonl` in the council root, which the watch hook of
      `kvb-org-organize` keeps in `~/.local/state/agents-council/` beside
      `gates.db`; reads merge both, and a database row for an edge wins.
 - [x] `gates.py resolve --repo R --branch B --action A` prints the level and its
      source: the branch's own rule, else the strictest resolved level of all
      ancestors, else none.
 - [x] The post-checkout hook records as parents every local branch whose tip
      equals the new branch's start commit; `gates.py parents derive` adds
      derived parents for the others.
 - [x] A green queue gate writes a receipt: repo, tree sha of the tested content
      (tracked, staged, unstaged, untracked, via a temporary index), level,
      log, time. It also carries `INFINITO_TEST_GPU` as `gpu`; above quick only
      `false` counts, and a run that changed the tree writes none.
 - [x] `gates.py hooks install --repo R` installs pre-commit (quick checks of the
      staged files, under 30 s on this repository), commit-msg,
      pre-merge-commit, pre-push and post-checkout.
 - [x] commit-msg, pre-merge-commit and pre-push pass when a receipt for the
      resulting tree meets the resolved level, else refuse with the
      `queue.py hold` command that produces it; each check stays under 1 s.
      For the level quick the command is `gates.py quick`, which starts
      nothing heavy (Main's condition 3). pre-push also needs the remote
      branch's merge level, so a fast-forward or squash merge, which no merge
      hook sees, cannot leave without its receipt; commit-msg warns on a
      squash commit early; a detached HEAD takes the rebased branch, else the
      default branch; `hooks install` changes no git config.
 - [x] `queue.py hold` for a task whose `after` tasks are not all done waits with
      `waits for <task>`; the register rank places a task after its `after`
      tasks.
 - ~~The commit skills commit through the hooks; `--no-verify` only on the
  operator's word for that commit.~~ Rejected by the operator 2026-11-12:
  agents keep --no-verify, hooks bind humans and CI (Main condition 2,
  Experiment condition 4).
 - [x] Experiment's and Main's answer on core's hooks is recorded here; core's
      `.pre-commit-config.yaml` changes only in a core PR.
  - Main (2026-11-12) agrees for the skills repo, four conditions: (1) the
    receipt binds the exact tree id of the commit plus the resolved level; a
    merge or amend without a fresh green gate on that tree fails it. (2)
    Operator rules stay: commits and handed-over pushes run with
    `--no-verify`, so the hooks are a second line, never the only gate check;
    `kvb-git-push` still verifies quality-high on the exact commit, and an
    explicit per-push waiver from the operator stays possible.
    (3) pre-commit quick checks start nothing heavy: no make test, no Docker,
    nothing that belongs in `queue.py hold`. (4) No oracle tests and GPU off
    in the resolved level.
  - Experiment (2026-11-12) agrees, no veto: (1) every core branch's level is
    quality-high with GPU off; no lower per-branch level without the
    operator's word. (2) A receipt binds the exact tree sha plus level plus
    `INFINITO_TEST_GPU=false`; a run whose docs or autoformat step wrote
    files, or one on another tree, never counts. (3)
    `~/.local/state/agents-council` is outside the sandbox write scope, so
    sandboxed gates write receipts to `/tmp/agents-council` (the council
    root) and the watch hook of `kvb-org-organize` mirrors them to
    `~/.local/state/agents-council`, as it does `security-accepted.jsonl`.
    (4) Agents commit and push with `--no-verify` per operator rule, so the
    hooks bind humans and CI; the push hand-over keeps its own green gate on
    the exact commit.
  - Core's hooks and `.pre-commit-config.yaml` stay untouched here; they
    change only in a core PR agreed with Experiment and Main.
 ### W4 Resources
 - [x] `resources.py sample`, run every 60 s by a user timer that
      `make orchestrator-install` enables, appends one row: used and total per
      mount, CPU, RAM and swap percent, load, GPU utilization and VRAM per
      GPU, waiting and active queue jobs.
 - [x] An NVIDIA GPU whose PCI `runtime_status` is not `active` is recorded as
      asleep without running `nvidia-smi`.
 - [x] `resources.py tokens` adds input, output, cache-read and cache-write
      tokens per agent and model from transcript usage fields since the last
      byte offset; no sampler or parser calls an LLM.
 - [x] Rows older than 7 days fold into 15-minute means; means older than 90
      days are dropped.
 - [ ] The Resources entry shows on one time axis disks, CPU, RAM, swap, GPU,
      VRAM and stacked tokens per agent; bands mark idle (< 30 %) and
      saturated (> 90 %); a marker flags spans where jobs waited while CPU and
      RAM stayed under 50 %; the view reads only the sampler files.
 - [x] 001 S7 points to this section.
 ### Contracts
 The work packages meet only through these interfaces:
 - **Gates**: `skills/kvb-check-gate/scripts/gates.py` (its docstring is the
  reference). The hub reads `gates.py show --json`; a GUI change is a signed
  job whose argv is `rule set|drop` or `parents add|drop`
  (`signing.gate_argv`), run by the host runner with `--gates`.
 - **Register**: the board's signed task changes (`signing.task_argv`) accept
  `set <task>` with exactly one of `--status <s>`, `--after <t>`,
  `--drop-after <t>`, `--prio <n>` or `--unpin`; every changed row carries
  `updated` (ISO time), which Stale reads.
 - **Review diff**: the review request of `approval.py` gains `diff`, a list of
  `{path, status, mode, additions, deletions, patch, note}`: status one of
  A, M, D, R or B (binary), mode the git file mode (`old => new` when it
  changed), patch the unified text (empty for binary files, past the 2 MiB
  cap and for withheld content), note empty or "content withheld". An Ask
  for a `git commit` carries the same `diff` from `permission_hook.py`; a
  body past the hub's limit goes without it.
 - **Feedback**: a feedback is a message to the requesting agent through the
  existing signed message flow, text `Feedback on <ref> <path>:<from>-<to>:
  "<quote>" <text>`.
 - **Resources**: the host unit writes `samples.jsonl` (`{t, disks: [{mount,
  used, total}], cpu, ram, swap, load, gpus: [{name, util, vram_used,
  vram_total} | {name, asleep: true}], queue: {waiting, active}}`),
  `tokens.jsonl` (`{t, agent, model, input, output, cache_read,
  cache_write}`, t the hour), `offsets.json` and `cpu.json` under
  `~/.local/state/agents-council/resources/`.
 - **Mounts**: the hub mounts `~/.local/state/agents-council` read-only and
  opens `gates.db` read-only.
 ### W6 Speech bubbles
 - [ ] A `bi-chat-quote` toolbar icon (`title` and `aria-label` "Speech
      bubbles") switches the bubbles on and off for every view that shows
      agents (Agents graph, 3D, Hierarchy, Radio, Stream); the choice is kept
      in the hub settings and survives a reload.
 - [ ] One overlay layer (fixed, `pointer-events: none`) draws all bubbles; a
      DOM view anchors a bubble at the visible `[data-face]` element of its
      agent, the 3D view projects the agent's node through the camera on every
      frame; an agent without an anchor in the active view speaks from a
      caption bar at the bottom.
 - [ ] The bubble of `speech.current` is the largest (scale 1) and shows its
      line word by word, word i of n at i/n of `buffer.duration`; text beyond
      6 lines scrolls up inside the bubble. On `ended` it fades out within
      400 ms while the next item grows to scale 1 and starts.
 - [ ] Every item of `speech.pending` shows a `…` bubble at its agent, scaled
      by queue position: current 1, then 0.8, 0.65, at least 0.5, so the
      newest is the smallest; an agent with several waiting items shows one
      bubble at the size of its earliest.
 - [ ] With speech off, TTS unavailable or muted, the same rows run through the
      same queue timed at 180 words per minute, at least 1.5 s each.
 - [ ] Bubble text uses Comic Neue as a vendored woff2 with its SIL OFL 1.1
      text in `orchestrator/vendor/`, stack `"Comic Neue", "Comic Sans MS",
      cursive`; no external font request, the CSP stays unchanged.
 - [ ] Stop speaking clears every bubble at once; switching the bubbles off
      leaves speech playback unchanged; `prefers-reduced-motion` drops the
      scaling and scrolling animation.
 - [ ] Bubble text is set as text content, never as HTML.
 ### Simplicity
 - [ ] Every new control is a Bootstrap Icon with `title` and `aria-label`; no new
      visible text beyond counts and names.
 ### Tests
 - Unit:
  - [x] Board staging, lanes and refusals (cycle, open key result); forecast
        fixed, growing and never; stale; scope without `operator/*`.
  - [x] Gates resolve (own rule, strictest of several ancestors, none);
        parents derive; receipt tree sha with unstaged and untracked files;
        hook pass and refuse; queue wait on `after`.
  - [ ] Resources sample parsing on fixtures (df, meminfo, nvidia-smi, asleep
        GPU); token offsets; retention fold; diff cap and masking; feedback
        payload.
  - [x] W4 part of the item above: sample parsing on fixtures (df, meminfo,
        CPU ticks between runs, nvidia-smi, asleep and unread GPU); token
        offsets, a message counted once across fork transcripts; retention
        fold.
  - [ ] Bubble schedule: scale per queue position, word reveal times from a
        duration, reading-pace duration, one bubble per agent.
 - Integration:
  - [x] A scratch repository with installed hooks refuses a commit without a
        receipt and passes it after a queue gate; refuses a merge below the
        parent's level; post-checkout records parents.
  - [ ] The host executor applies a signed board batch to a scratch register
        and refuses a forged one; deletes a local merged branch without a
        token and refuses a remote one.
  - [x] The sampler writes rows in a scratch HOME.
 - E2E, headless Chromium and Firefox at 1920, 1366 and 390 px:
  - [ ] Tasks badge, no Inbox entry, operator cards with bulk actions, review
        diff expanded, feedback by right-click and `f` reaching the radio
        store.
  - [ ] Kanban lanes, no Blocked or Stopped column, drags to column, lane and
        dependency, Apply with a test passkey, arrows and the dashed queue
        line, card popup; forecast two lines and ∞.
  - [ ] Artifacts clean-all dry run, Ancestry in both tabs, a gate set;
        Resources charts; no page scrollbar.
  - [ ] Bubbles on: two radio rows without TTS show the first agent's bubble
        largest with its words appearing, the second as a smaller `…`; after
        the first ends the second grows; the setting survives a reload; off
        hides the layer.

 # 004 - Radio Set
 ## User Story
 As the operator of many parallel agents, I want the Agent Orchestrator radio
 to work like a minimalist marine VHF set, with every setting at hand, a
 filterable log and speech only when the host has CPU to spare, so that I hear
 that someone transmits without the speech engine loading a busy host.
 ## Decisions (operator-confirmed 2026-11-12; do not re-litigate)
 1. **CPU gate on the server**: `/api/tts` renders an uncached line only while
   the latest host CPU sample of the W4 resource feed (`samples.jsonl`, at
   most 120 s old) is below the threshold; a cached line is always served;
   otherwise it answers 503 with the reason `busy`, or `unknown` without a
   fresh sample. Rejected: a gate only in the browser (another tab or an old
   page still renders), browser `speechSynthesis` (same host CPU, other
   voices), rendering held-back speech later (stale).
 2. **Noise burst**: when no speech plays, the page plays a squelch-tail noise
   burst made by WebAudio in the browser (band-passed white noise, about
   0.6 s, at the tone's volume and squelch); no server request. Rejected: a
   recorded sound file.
 3. **Modes**: Auto (speech below the threshold, otherwise the burst), Quiet
   (the burst only, never speech), Silence (no sound; bubbles and log only).
   Default Auto.
 4. **Procedure words**: for MAYDAY, PAN-PAN and SÉCURITÉ the procedure word,
   spoken three times in the sender's voice, always sounds, in every mode and
   under load; under load or in Quiet the burst replaces the rest of the
   message. The word line is the same text every time, so after its first
   render per voice it is a cache hit.
 5. **Settings in the panel**: mode, volume per tone, squelch, read-aloud
   filters (classes, agents) and the internet radio station are radio-set
   buttons and controls in the radio panel; the radio section leaves the
   settings dialog. They live per browser, without a passkey. Rejected: signed
   hub settings (one passkey per button press).
 6. **Threshold**: adjustable in the panel, 30 to 90 % in steps of 10, default
   50 %; a signed hub setting `speech.threshold`, since the server enforces
   it. Rejected: a fixed 50 %.
 7. **Log**: tabs Sent (from the operator), Received (to the operator or to
   all) and All (every radio row the hub logs); filter chips class, sender,
   recipient and agent plus text search, combined with AND, newest first.
   Rejected: Received as all agent traffic.
 8. **Look**: one faceplate inspired by a marine VHF set, functional and
   minimalist: a display line (class, mode, CPU, TX/RX lamp), a row of mode
   buttons, sliders as knobs, a PTT send button; palette tokens, light and
   dark, no textures. Rejected: a full VHF set with dual watch, scan and DSC
   (high effort, no gain).
 9. **Order**: builds on W4's resource feed; implementation starts once W4 is
   on master.

 ## Acceptance Criteria
 ### Server gate
 - [ ] `POST /api/tts` with an uncached line answers 503 `{"reason": "busy"}`
      while the latest `samples.jsonl` row has `cpu` >= the threshold, and the
      fake Piper records no call.
 - [ ] Without a sample younger than 120 s it answers 503
      `{"reason": "unknown"}`, and the fake Piper records no call.
 - [ ] A cached line answers 200 whatever the CPU.
 - [ ] Below the threshold an uncached line renders as before.
 - [ ] `GET /api/state` carries `speech.gate` with `threshold`, `cpu` and
      `open`.
 - [ ] `speech.threshold` accepts only 30 to 90 in steps of 10, default 50,
      and changes only with a valid passkey signature.
 ### Sound
 - [ ] Auto below the threshold: the page plays the spoken line; on a 503 it
      plays the burst once and does not retry that row.
 - [ ] Quiet: the page sends no `/api/tts` request except for procedure-word
      lines, and every row plays the burst.
 - [ ] Silence: no audio node starts except for a procedure-word line.
 - [ ] The burst is WebAudio noise of 0.4 to 0.8 s at the tone's volume times
      the squelch, and it sends no network request.
 - [ ] A MAYDAY, PAN-PAN or SÉCURITÉ row requests its procedure-word line
      first, in every mode; the second such line for the same voice is a
      cache hit with no Piper call.
 ### Panel
 - [ ] The display line shows class, mode, CPU % and a TX/RX lamp that is lit
      while sound plays.
 - [ ] Auto, Quiet and Silence form one button group (`aria-pressed`); a press
      changes the mode without a passkey and survives a reload.
 - [ ] Volume per tone, squelch, the read-aloud filters for classes and
      agents, and the internet station sit in the panel; the settings dialog
      has no radio section.
 - [ ] The threshold control asks for the passkey once per change and shows
      the server's value.
 - [ ] At 1920, 1366 and 390 px the panel has no horizontal scroll, in the
      light and the dark palette.
 ### Log
 - [ ] Tabs Sent, Received and All show their counts; Received holds exactly
      the rows addressed to the operator or to all.
 - [ ] The chips class, sender, recipient and agent and the text search
      combine with AND; one control clears them all.
 - [ ] Rows run newest first with time, direction, class badge,
      sender → recipient and text; a click opens the full message.
 - [ ] Tab, chips and search survive a reload in the same browser.
 ### Tests
 - **Unit**: gate busy, unknown, cache hit and open; threshold validation;
  procedure-word lines from `phrasing.py`; every case with a negative
  control.
 - **Integration**: hub HTTP tests with a fake Piper and a fake
  `samples.jsonl`: 503 and no Piper call under load, 200 for a cache hit,
  `speech.gate` in `/api/state`.
 - **E2E**: Playwright in Chromium and Firefox at 1920, 1366 and 390 px: mode
  buttons, burst through a spy on the AudioContext, procedure word under
  load, the settings dialog without a radio section, the log tabs and
  filters.

 """Args:
    cwd: the working directory whose repository the diff is taken of.
    everything: False for the staged tree against HEAD (git diff --cached),
        True for what git commit -a records (every index path as it lies in
        the working tree) against HEAD.
    tree: for tree_diff, the tree object (git write-tree) diffed against
        HEAD instead of the live index.
    rules: the MEDUSA rules directory, None when MEDUSA is not installed.
    pinned: for bound_diff, what binding returned for the same cwd and everything.
 Returns:
    review_diff, tree_diff, bound_diff: the review diff of requirement 003,
        one {path, status, mode, additions, deletions, patch, note} per
        changed path, sorted by path, status A, M, D or B (binary); path is
        the file name with bytes that are no UTF-8 written as backslash
        escapes; mode the git file mode, "old => new" when it changed (with
        everything, the executable bit on disk). patch holds the unified
        hunks; it is empty for a binary file, a gitlink, a side over
        BLOB_LIMIT bytes (counted 0/0), a path sandbox_paths denies (its
        FLOOR and the settings' deny lists) and every file past DIFF_LIMIT
        bytes of JSON-encoded patch text. A file whose old or new content
        holds an ARMOUR line or matches a MEDUSA secret rule for its name,
        and every file when no secret rule pattern loads, ships no patch,
        only its counts and the note WITHHELD. With everything, a working
        tree file over BLOB_LIMIT or under a denied path is not read and so
        always counts as changed. The diff fails when more than FILE_CAP
        paths changed or one is longer than PATH_LIMIT, a settings file
        sandbox_paths reads is unreadable, the working tree lies under a
        denied path, HEAD exists but its tree cannot be listed, HEAD is
        neither a commit nor unborn, or for bound_diff, the working tree
        changed while it was read.
    binding: what a commit records, for the permission hook to bind an
        allow to: the tree git write-tree prints; with everything, joined by
        the digest of every index path's mode and content id as it lies in
        the working tree, a file not read by its size, inode and times.
    commit_of: the directory and -a mode of a single git commit whose
        preview matches what it records, None for any other command.
 Only git plumbing runs (rev-parse, symbolic-ref, ls-tree, ls-files, cat-file,
 write-tree) with core.fsmonitor and lazy fetching off, and the diff itself is computed here:
 the permission hook calls this outside the sandbox in a directory the agent
 chose, where a planted repository config, filter, diff driver or promisor
 remote must start no program, and a working tree path must not lead the read
 through a symlinked directory, out of the working tree or into a path the
 sandbox denies reading.

    --council: directory holding rasci.json, news.jsonl, queue-history.jsonl,
        night.json, radio-silence.json and the claims under cluster/*/ and
        work/*/; a missing file leaves its part of the state empty. The board
        actions change it through the skill scripts.

        messages.json, rules.json, jobs.json, marks.json, settings.json,
        log.jsonl, the page copies, uploads/<id>/<name>, the operator's last

    --tree-file: the JSON file `pkgmgr branch tree --output` writes, mounted
        read-only; read again whenever it changes.
    --timers: directory holding the systemd user units (*.timer).
    --kept: ~/.local/state/agents-council, mounted read-only: gates.db and
        the resources/ files of the host sampler.
    --vendor: directory holding the vendored Bootstrap Icons sprite,
        3d-force-graph and three with their licence texts.
    --cleanup: host-mounted directory the hub writes signed branch deletions
        into (jobs/) and reads their results from (results/); the host's
        kvb-orchestrator-cleanup path unit runs them.
    --offices: host-mounted directory the hub writes signed office orders
        (appoint, take over, recall) into (jobs/) and reads their results
        from (results/); the host's kvb-orchestrator-offices path unit runs
        council.py for them.
    --llm-url: base URL of an OpenAI-compatible chat endpoint; empty turns the
        natural-language command line off.
    --llm-model: model name sent to that endpoint; empty turns it off.

    --whisper: the whisper.cpp command line executable; missing turns speech
        input off.
    --whisper-model: the ggml model whisper.cpp loads.
    --scratch: writable directory the engines use as HOME and TMPDIR.
    --approvers: the pinned passkeys, mounted read-only; the hub lists their

        only for the operator messages, denials and rules it acts on itself,
        and for the mayday and day/night board actions and new stream origins
