+# Local → production pipeline.

+#   push to main → test → build amd64 images → push to the fleet registry
+#   → move :latest → gw-04's existing 60s rolling timer picks it up.
+#
+# The last hop is NOT in this file and does not need to be: gw-04 already runs
+# `clawmates-deploy.timer` every minute, which pulls
+# `$REGISTRY/clawmates/<svc>:latest`, compares it to the running image id, and
+# recreates on drift. This workflow's job is to make `:latest` mean the newest
+# green commit. See deploy/gw-04/clawmates-deploy.sh.
+#
+# Runs on the `gw04` runner (host executor, systemd unit act-runner). gw-04 is
+# the only reachable x86_64 host — web-01 is aarch64 and the fleet build boxes
+# are packed — and prod images must be linux/amd64, so builds are native here
+# rather than emulated.

+//! Host side of a microVM's only route out: an HTTP `CONNECT` proxy on a Unix
+//! socket, one per VM.
+//!
+//! # Why the guest has no network card
+//!
+//! It could have had one. A TAP device plus NAT is what the Firecracker
+//! write-ups do, and it was measured against this before being rejected:
+//!
+//! - `ip tuntap add` is **denied to the daemon user** (needs `CAP_NET_ADMIN`), so
+//!   TAP would need root to pre-provision devices at setup time — the same
+//!   privilege detour the loop-mounted rootfs already forced.
+//! - tank's `FORWARD` policy is `DROP` with Docker and Tailscale chains, so rules
+//!   would have to be *inserted* at position 1; appended ones die silently.
+//! - a leaked TAP device is a new class of host litter to reap.
+//!
+//! Against that, `CONNECT` needs no privilege at all, and it is better on the
+//! merits: the client hands us the **hostname**, so resolution happens here and
+//! the guest needs no DNS or `resolv.conf`; the allow-list is by name rather than
+//! by address; and nothing in the guest can reach the network except through this
+//! function. That is what the isolation plan's egress restriction actually asked
+//! for, and it is strictly tighter than the mission container's present full
+//! egress on `clawmates_edge`.
+//!
+//! The design rests on one measured fact: **`claude` honours `HTTPS_PROXY`**.
+//! With the proxy pointed at a closed port, `claude -p` fails with
+//! `ConnectionRefused` instead of answering. (That could only be measured in a
+//! container — inside a VM the CLI collapses every failure into `Execution
+//! error`.)
+//!
+//! # Shape
+//!
+//! Firecracker's convention for a guest-initiated connection is that the **host**
+//! listens on `<uds_path>_<port>`. The guest's agent pumps bytes from
+//! `127.0.0.1:3128` to vsock port 9002 and parses nothing, so all policy is here
+//! and a compromised guest cannot argue with it.

+//! Host side of a microVM's route to the node's OWN locally-hosted model.
+//!
+//! # Why this is not the egress proxy
+//!
+//! [`crate::egress`] exists so an agent can reach the public internet under an
+//! allow-list: it speaks HTTP `CONNECT`, takes a destination from the guest,
+//! resolves it, and decides. Every one of those powers is a liability, which is
+//! why that module is careful about ports, IP literals and suffix matching.
+//!
+//! This is the opposite shape. There is **no destination in the protocol**. The
+//! guest opens a socket; the host connects it to `127.0.0.1:11434` on the node
+//! and copies bytes. A compromised guest can ask for nothing else, because there
+//! is nothing to ask — it is a pipe, not a proxy. That is strictly narrower than
+//! anything the allow-list could express, and it is why routing a local model
+//! through `egress` would have been the worse design: it would have meant
+//! relaxing the 443-only rule and the IP-literal refusal, both of which exist
+//! because a unit test caught them being bypassed.
+//!
+//! # Why plaintext is right here
+//!
+//! The bytes go guest loopback → vsock → host loopback. They never touch a
+//! network, so there is no wire for TLS to protect. Ollama stays bound to
+//! `127.0.0.1` on the node and is never exposed to the tailnet, which is a
+//! stronger position than terminating TLS in front of it would have been.
+//!
+//! # Why it is per-backend
+//!
+//! The node binds this socket only for a backend declared to use a local model.
+//! On every other backend the guest's listener is still there and simply gets a

+//! agents bound to nothing at all — indistinguishable, in the UI, from the
+//! operator's own staff.
+//!
+//! The discriminator is `agent_template_link`. `mission_orchestrator` writes one

+//! for. An agent WITHOUT that row was created by a human (or the planner) and is

+//! Merging a delivered branch into the base, when that is provably safe.
+//!
+//! Every mission type delivers to a branch and never to `main`. For most that
+//! is where it should stop — a human reads the code and merges. But some
+//! missions only ever *add* files in a folder they own: a paper catalogue, a
+//! benchmark record. Those branches carry no judgement call, and leaving them
+//! to pile up unmerged means the work is done but not actually in the vault.
+//!
+//! # Additive-only is a property, not a preference
+//!
+//! The gate is not "is this mission type trusted". It is measured from the
+//! diff: if the branch modifies or deletes anything that already existed, it
+//! does not qualify, whatever its template says. A research harvest that
+//! somehow rewrote a hand-written note would be refused by the same check
+//! that lets its new notes through.
+//!
+//! Three conditions, all required:
+//!
+//! 1. the mission type declares [`MergePolicy::AdditiveOnly`]
+//! 2. verification passed — a run that did not prove its work does not merge
+//! 3. the diff against the base contains only additions
+//!
+//! Anything else lands as a branch for a human, which is the existing

+//! What a continuous mission has already covered.
+//!
+//! A recurring mission's hard problem is not running the agent — that is 23
+//! seconds — it is knowing what it already did last time. A research mission
+//! with no memory of prior runs resurfaces the same papers forever and reports
+//! success every time.
+//!
+//! This module keeps that record. It is deliberately small: an index derived
+//! from the corpus, never the corpus itself. The vault is the source of truth,
+//! the index is rebuildable, and a hand-edited note is never "wrong".
+//!
+//! # Two kinds, because the real vault forced it
+//!
+//! The plan assumed notes would carry `arxiv:` / `doi:` / `url:` frontmatter.
+//! Measured against the actual vault: **416 notes, 145 with frontmatter, and
+//! zero with any of those keys.** The dominant keys are repo-sync metadata
+//! (`node`, `org`, `gitea`) and course-note fields (`presenter`, `session`).
+//! An ingester keyed only on external identity would have indexed nothing —
+//! the same shape of failure as everything else this week.
+//!
+//! So `note` rows record coverage (what the vault already contains, keyed by
+//! path) and `source` rows record consumption (external things a mission
+//! read, keyed by natural id). They answer different questions and a
+//! continuous mission needs both: "have I already written about this topic?"
+//! and "have I already read this paper?".

+//! One run of the library: find, skip what we have, shelve the rest.
+//!
+//! This is the piece that makes the others a *job* rather than parts on a
+//! bench. Order matters and it is deliberate:
+//!
+//! 1. **search** arXiv for candidates
+//! 2. **skip** everything already on the checkmark list — before any download
+//! 3. **fetch** the PDF for what is left, and verify it really is a PDF
+//! 4. **shelve** it in the blob store
+//! 5. **catalogue** it: write the vault note
+//! 6. **check it off** so next week skips it
+//!
+//! Step 2 comes before step 3 on purpose. Checking after downloading would
+//! still dedupe the catalogue, but it would re-download every paper we already
+//! have, every week, forever — and the whole point of the checkmark list is to
+//! not do the work twice.
+//!
+//! # Nothing new is a success, not a failure
+//!
+//! A weekly run that finds no new papers has worked correctly. A run that
+//! *crashed* has not. [`Harvest`] keeps those apart, because collapsing them
+//! is precisely the "reported success while doing nothing" shape that this
+//! codebase has been bitten by repeatedly. `shelved == 0` with `failed.empty()`

+//! A process-wide push bus for live taxonomy events.
+//!
+//! `/api/world/live` is a 2-second database poll. That is the right shape for
+//! state you can query — statuses, phases, telemetry — and the wrong shape for a
+//! token stream: an agent's reasoning only becomes visible after the step
+//! finishes and its text is persisted, so the REASONING STREAM card showed
+//! completed paragraphs rather than an agent thinking.
+//!
+//! This carries the frames that cannot wait for a round trip through Postgres.
+//! `topology_exec` publishes as the runtime's WebSocket delivers them; the SSE
+//! handler subscribes and forwards, so a chunk reaches the browser in one hop.
+//!
+//! **Why a global rather than a field on `AppState`.** The publisher is
+//! `topology_exec`, reached through `phase_runner` → `topology_worker` →
+//! `MissionTap`, none of which hold `AppState`. Threading a handle through all
+//! of them would put a UI concern into four layers that have no other reason to
+//! know about one. There is exactly one bus per process and it holds no
+//! per-request state, so a `OnceLock` is the honest representation.
+//!
+//! **Lossy on purpose.** A slow reader lags and skips rather than applying
+//! backpressure to the agent that is producing. Dropping frames degrades a live

+//! Drive a fleet node's microVMs from the server.

+//! Thin by design: the node owns the VM lifecycle (see

+//! there is no new transport, correlation or timeout machinery.
+//!
+//! # Not a `SandboxDriver`
+//!
+//! `RemoteDriver` exists to marshal `SandboxDriver` over the hub, and reusing it
+//! was the plan. That trait is container-shaped — `attach_pty`, `resize_pty`,
+//! argv `exec` — while a mission needs inject → run → collect. Conforming would
+//! mean implementing PTY-over-vsock semantics that nothing calls, so this speaks
+//! the smaller interface the mission path actually uses.
+//!
+//! # Timeouts
+//!
+//! The hub defaults to 20s, which is right for a create (measured: ~1s) and
+//! badly wrong for an agent turn. `exec` therefore takes its own budget and
+//! passes it to BOTH the hub and the guest, with the hub's slightly longer: if
+//! the guest's own timeout fires first the reply says so, whereas a hub timeout

+//! The two engines composed — Slice 4.
+//!
+//! Engine Z (the ZeroClaw graph in `cm_orchestrator`) owns durability and
+//! heterogeneity: deterministic planners, per-step checkpoint/resume, a stale-run
+//! sweep, cancellation, and a different model per node. Engine C (Claude Code in
+//! a microVM) owns shared context, self-sizing and cheap fan-out. Neither has the
+//! other's asset, which is why keeping both is a composition rather than a
+//! compromise.
+//!
+//! This module is the join: a [`TurnExecutor`] whose "turn" is a whole
+//! Claude-Code-in-a-VM session. Because `topology_worker` already dispatches by
+//! tier, implementing the existing trait inherits the planners, checkpointing,
+//! reaper, cancellation, `close_finished_phases`, evaluation, capture and
+//! delivery unchanged. `recursive_exec::SubTopologyExecutor` is the precedent: a
+//! `run_turn` may be arbitrarily heavy.
+//!
+//! # The file-handoff trap
+//!
+//! A VM is inject-tar → run → collect-tar → destroy. A graph of per-node VMs with
+//! **text-only** handoff would silently lose every file an earlier node wrote:
+//! node 2 would boot from the original checkout, see none of node 1's work, and
+//! still report success — the exact silent-success shape this project keeps
+//! paying for.
+//!
+//! The answer here is that the mission's **host checkout is the medium**. Every
+//! node injects from `repo` and collects back over `repo`, so the tree carries
+//! forward node to node and the last node's tree is what delivery diffs. Two
+//! properties make that safe rather than lucky:
+//!
+//! - `execute_resumable` runs steps strictly **sequentially**, so two VMs are
+//!   never writing the same host directory at once;
+//! - the vm id is deterministic per (phase, iteration, step), so a resumed step
+//!   whose VM is somehow still alive is refused by the node ("vm already exists")
+//!   instead of quietly producing a second writer.
+//!
+//! `a_later_node_sees_an_earlier_nodes_files` proves the handoff, and
+//! `text_only_handoff_loses_the_earlier_nodes_work` is its negative control.
+//!
+//! # Keeping a long turn alive
+//!
+//! `requeue_stale` requeues a `running` job that has not touched `updated_at` in
+//! 180 seconds, and one node here can run for an hour. `SubTopologyExecutor`
+//! keeps its parent alive from each *leaf step*, which it has and this does not:
+//! there is nothing between the start and end of a VM turn. So the turn holds a
+//! ticker that touches `updated_at` every [`KEEPALIVE_SECS`] and is aborted on
+//! drop. Without it a healthy composed run is requeued mid-node, claimed again,
+//! and boots a second VM against the same checkout.

+//! Move a mission's checkout in and out of its container, instead of sharing it.

+//! it has produced:
+//!
+//! | Symptom | Fix that was needed |
+//! |---|---|
+//! | `.git/objects` permission denied | `core.sharedRepository=0777` |
+//! | capture base overwritten each phase | advance the base after commit |
+//! | `.git/COMMIT_EDITMSG` root-owned | unlink before commit |
+//! | `reset --hard` deleting a prior phase | `.git/clawmates-in-use` marker |
+//!
+//! Four fixes, one cause. `core.sharedRepository` was never a general
+//! solution — it covers objects and refs, and every *other* file git touches
+//! is a fresh opportunity.
+//!
+//! Copy-in/copy-out removes the cause: the agent owns its filesystem
+//! completely, as root, with no other writer. Nothing on the host is shared,
+//! so nothing on the host can collide.
+//!
+//! # Cost

+//! # Why this is filesystem-first
+//!
+//! `cleanup_sweeper` prunes ROWS. Deleting a row does not delete a directory,
+//! and the reaper that was supposed to — `mission_runtime::teardown_container` —
+//! only runs while a mission still exists to tear down. So a mission deleted by
+//! any path that did not go through teardown left its directory behind forever,
+//! and the gateway is the smallest disk in the fleet (150 GB, shared with
+//! postgres and every checkout).
+//!
+//! The DB is therefore the PREDICATE here, never the enumerator: this walks the
+//! filesystem and asks the database about what it finds. Enumerating from the
+//! database is precisely how the orphans became invisible — a directory whose
+//! row is gone is exactly the one a row-driven sweep cannot see.
+//!
+//! # Why deletion needs two attempts
+//!
+//! The server runs as uid 65532. Almost everything under a mission belongs to
+//! 65532 now, but the per-mission ZeroClaw daemon still runs as root and leaves
+//! ~26 of its own files (`.claude.json`, session jsonl). `remove_dir_all` then
+//! fails with `PermissionDenied` and the directory survives — the
+//! cleanup-that-cannot-clean-up shape, at a scale small enough to go unnoticed.
+//! So a failed removal falls back to `root_copy::purge`, which deletes from
+//! inside the runtime container as root.
+//!
+//! # What it will not touch
+//!
+//! Anything belonging to a mission that still has a row, and anything younger
+//! than the grace window. A mission directory is created BEFORE its row is
+//! committed in some paths, and reaping a directory out from under a launching
+//! mission would be a far worse bug than the leak this fixes.

+//! mission (`per-mission-crews`: reuse is OFF by operator decision), so a
+//! brain keyed by agent would be written once and never read. What persists
+//! across missions is the repository. So the memory is keyed by `repo_id`:
+//! one `.brain` per repo, holding the judge's verdicts, recalled by the next
+//! mission's task text and placed in its brief.
+//!
+//! What is remembered is the verdict, not the work: for a met phase the
+//! judge's `reason` (what it found), for an unmet one its `guidance` — the
+//! agent-facing half, already stripped of acceptance literals by
+//! `evaluator::sanitize_guidance`, because a verdict quoted verbatim into
+//! the next brief is how the 2026-08-01 Goodhart incident happened.
+//!
+//! Recall is BM25 over the keyword index (`cm_brain::ClawBrain::recall`);
+//! there is no embedder. Measured before anything richer is built: the test
+//! is a second mission on the same repo recalling the first's verdict.

+//! Capture for missions that have no repository.
+//!
+//! `mission_delivery` captures a phase's work by diffing a git checkout. A
+//! mission with `repo_id IS NULL` — every `research_only` mission, because that
+//! recipe sets `requires_repo = false` — has no checkout, so
+//! `capture_finished_coding_phases` filters it out at the SQL level
+//! (`AND m.repo_id IS NOT NULL`) and never reads the container at all.
+//!
+//! The agents still write files. The research directive tells them to save
+//! findings under `/mission/repo/research/`, and it says so whether or not a
+//! repo exists. So the work lands in the container's own filesystem, is never
+//! collected, and is destroyed when the sweeper reaps the container.
+//!
+//! # What this cost, measured
+//!
+//! Mission `019fdc35` ("ClawHDF5 Research"): four agents, 9.5 minutes, **eight
+//! research documents** — an HDF5 parser design, a Rust ecosystem survey, a
+//! seven-crate dependency map, tracing and fuzzing strategy. `mission_artifacts`
+//! held zero rows and the mission reported `completed`. One agent's own summary
+//! recorded the situation exactly: *"No git repo — file is written."* It noticed,
+//! wrote anyway, and the platform threw the result away without a word.
+//!
+//! Nothing survived but the summarizer's account of it — which is the agents'
+//! description of the work, not the work.
+//!
+//! # Why a separate path rather than widening the diff capture
+//!
+//! There is no base commit to diff against and no branch to push, so every
+//! concept `capture_phase_diff` is built on is absent. What a repo-less mission
+//! produces is simply *files*, and the honest capture is to copy them out and
+//! register each as an artifact. `_outputs/` is deliberately a SIBLING of the
+//! mission directory and survives `teardown_container`, so artifacts registered
+//! here outlive the reap that destroyed the originals.

+//! A model-authored execution plan for one mission — W1 / #13.
+//!
+//! Every mission's phases come from one of five hand-written recipes in
+//! `templates/workflows/*.toml`, chosen by `template_kind`. A recipe is a fixed
+//! answer to "what phases does this kind of mission have", written before anyone
+//! saw the mission — the "do it this way: 1, 2, 3" over-specification that makes
+//! a capable model follow a worse plan than it would have chosen for the actual
+//! task.
+//!
+//! This is the other half of [`crate::mission_roster`]: that one lets a model
+//! size the team, this one lets it decide what the work IS. Same shape on
+//! purpose — propose, review, approve, apply — because the review gate is what
+//! makes model-authored structure safe to run, and a second shape would be a
+//! second thing to get right.
+//!
+//! # Grounded in what the platform actually reads
+//!
+//! The interesting constraint is not "is this JSON valid" but "will anything
+//! consume it". `phase_config::KNOWN_KEYS` already names every phase-config key
+//! and the code that reads it, with eleven marked NOT IMPLEMENTED — the registry
+//! built after `task` sat unread through every mission. A plan is validated
+//! against that registry, so a model cannot propose a phase whose settings
+//! nothing will act on. The failure that registry exists to EXPOSE is one this
+//! path cannot create.
+//!
+//! Phase kinds are checked the same way, against the kinds `phase_runner`
+//! actually dispatches. A model asked to plan work will happily invent
+//! `kind: "review"`, and an unknown kind does not fail — it falls to the
+//! catch-all purpose and runs as a generic phase, which looks like it worked.

+//! A model-authored roster for a mission — Slice 5.
+//!
+//! The Master Planner has been proposing teams (2-6 members, a model each) since
+//! it shipped, and none of it reached a mission: the proposal lived in React
+//! state. A mission's shape came instead from a team template — fixed roles, and
+//! every claw minted `claude-sonnet-5`, which is why no mission has ever run
+//! heterogeneous providers.
+//!
+//! This is the seam. A roster is `(topology_kind, [(role, backend)])`, which is
+//! exactly what the composed executor consumes: `composed_graph` turns it into a
+//! `TopologyGraph`, and `MicroVmTurnExecutor` reads `attrs["backend"]` per node,
+//! so a `validator` role on a different provider's rootfs is a first-class graph
+//! node rather than a bolt-on.
+//!
+//! # Why the backend is validated here and not at boot
+//!
+//! Placement already refuses a mission whose backend no online node can run —
+//! but it refuses it at LAUNCH, after the roster was approved, the mission was
+//! created and someone believed it was going to run. A model that invents
+//! `rootfs-opus` is a normal thing for a model to do; discovering it three steps
+//! later is not. So a roster naming a backend the fleet cannot run is rejected
+//! when it is proposed, naming the backends that do exist.
+//!
+//! # What it deliberately does not do
+//!
+//! It does not mint claws. A composed mission's nodes are VMs, and provisioning
+//! containers for them would create agents and `.brain` files nothing ever
+//! dials — the same reason `on_launch` returns early for a microVM mission.

+//! Launching missions that are due.
+//!
+//! `missions.schedule` has carried a cron since `0047_missions.sql` — the
+//! wizard collects it, the API persists it — and until this module nothing ever
+//! read it back. The only due-work enumerator in the codebase was
+//! `routines::claim_due`, so **every scheduled mission ever created sat in
+//! `draft` forever** while the UI reported it was on a schedule. Measured
+//! before this was written: a mission with `* * * * *` did not move for four
+//! minutes and started no runs.
+//!
+//! The shape here is deliberately `cm-scheduler`'s, not a second invention:
+//!
+//! - **Claim atomically** (`FOR UPDATE SKIP LOCKED`) so replicas fire once.
+//! - **Advance the clock before dispatching**, so a failing launch cannot stall
+//!   the schedule.
+//! - **Record the claim first** in `mission_fires`, keyed by the occurrence's
+//!   own timestamp, so a crash between those two is retried rather than
+//!   silently dropped — and a slot already launched is never launched twice.
+//! - **Cap the fan-out**, because a backlog would otherwise start one container
+//!   per missed occurrence.
+//!
+//! The one thing it does NOT share with routines is the launch itself: a due
+//! mission goes through `mission_orchestrator::on_launch` and
+//! `missions::set_status`, exactly as the draft→running transition in
+//! `routes::missions::set_status` does, so there is one path that mints a crew.

+//! Finding papers, shelving them, and cataloguing them.
+//!
+//! The library has three parts and it matters which is which:
+//!
+//! - **arXiv** is where papers are *found*.
+//! - **The blob store** is the *shelf* — the PDF itself lives there.
+//! - **The vault** is the *card catalogue* — a markdown note per paper, with
+//!   the metadata and a pointer to the shelf.
+//!
+//! Plus [`crate::corpus`], which is the list of checkmarks: it is what stops
+//! the same paper being fetched twice across weekly runs. That list is the
+//! reason this can be a *continuous* job rather than one that redoes itself
+//! forever — the failure that killed the previous attempt at this (migrations
+//! 0030-0044, dropped in 0053).
+//!
+//! # The contract that ties it together
+//!
+//! Every note this module writes carries `source_id: arxiv:NNNN.NNNNN` in its
+//! frontmatter. `corpus::parse_note` reads exactly that key, so re-indexing
+//! the vault re-derives the checkmark list from the notes themselves. The
+//! catalogue is authoritative; the index is rebuildable from it. If the
+//! database were lost, a re-index of the vault would restore what we have.

-//! LLM + Chromium PDF renderer worker — Slice 6.
-//!
-//! Watches `mission_artifacts` for rows with `render_pdf_status =
-//! 'pending'`. For each:
-//!   1. Read the source MD from `<mission_root>/<path>` on disk
-//!   2. Call the configured LLM (default: Gemini 2.5 Flash) with a
-//!      "produce styled HTML" prompt anchored to a design-system
-//!      example. LLM writes HTML with inline CSS.
-//!   3. Print that HTML to PDF via `chromium --headless
-//!      --print-to-pdf`
-//!   4. Save the PDF alongside the MD, update `rendered_pdf_path` +
-//!      status = 'done'
-//!
-//! Graceful degradation: if `GEMINI_API_KEY` is unset or the
-//! chromium binary isn't on PATH, the worker marks the row `failed`
-//! with a descriptive error rather than blocking boot. Ops enables
-//! rendering by wiring both.
-//!
-//! The frontend already renders `rendered_pdf_path` as an "Open PDF"
-//! button on artifact cards (Slice 2).

+//! next phase's `cargo` hits permission-denied on a directory it cannot write.
+//! The harness's uid probe reports it as `uids=0,65532`.
+//!
+//! # The cleanup half, which is the part that keeps being got wrong

+//! The copy inherits the same problem: its `target/` is root-owned, so the

+//! survives forever — measured at 1.2 MB per benchmark run and 16 MB of stranded

+//! Slice 5. The planner has been proposing rosters into React state for months;
+//! this is where one reaches a mission. Three verbs, and the split between them
+//! is the point:
+//!
+//! - **suggest** asks the model and PERSISTS the answer. It changes nothing
+//!   about the mission.
+//! - **approve** writes the roster onto the mission, where the composed executor
+//!   reads it.
+//! - **reject** records that a human said no, which is the only evidence we ever
+//!   collect about what the planner gets wrong.
+//!
+//! A proposal is never applied on arrival. A model sizing a team is a suggestion
+//! about how many VMs to boot, and this codebase has an explicit rule about
+//! model output that costs money: it is evidence for a decision, not the
+//! decision.

+small change; Anthropic measure multi-agent work at 3-10x the tokens with wall-clock often LONGER, and \
+the benefit is thoroughness rather than speed.\n\n\
+Members run SEQUENTIALLY and share the repository, so do NOT propose members that would edit the same \
+file, and do NOT split one change into stages (plan → implement → test) — a handoff loses context at \
+every step and one careful pass beats an assembly line. The shape that DOES earn its cost is an \
+implementer followed by an independent verifier that only checks.\n\n\
+Give each member a `backend` ONLY when running it on a different provider's image is the point — an \
+independent verifier on another provider breaks the correlated failure where the model that wrote the \
+code also grades it. Omit `backend` to inherit the mission's.\n\n\

+//! Run a whole mission as ONE headless agent session.

+//!
+//! # Why
+//!
+//! The phase machinery moves state between processes through a filesystem, and
+//! that seam produced most of a week's defects: two uids fighting over
+//! `.git/objects`, a missing git identity, `reset --hard` deleting the
+//! previous phase's work, a capture base overloaded with two meanings. None of

+//! handoff to get wrong — step two knows what step one did because it is the
+//! same context.
+//!
+//! Measured against the same task (create a file, read it back, extend it,
+//! push it): the phase path took nine production runs and five distinct bug
+//! fixes to do reliably; a single session did it in 23 seconds, 19 times out
+//! of 20, first try.
+//!
+//! # What this deliberately does NOT trust
+//!
+//! The agent's own account of what it did. In the same 60-run experiment one
+//! session exited 0, ran for 18 seconds, and pushed nothing — a clean exit

+//! How a mission agent receives the skills bound to it.
+//!
+//! Two arms, and this module exists to hold them side by side rather than to
+//! replace one with the other:
+//!
+//! - [`Mode::Inline`] — every pinned skill's full body is appended to the turn
+//!   prompt. What production has always done.
+//! - [`Mode::Index`] — the prompt carries each skill's name, description and
+//!   `when_to_use` plus the URI that returns its body, and the agent fetches
+//!   the ones it judges relevant through the MCP door.
+//! - [`Mode::Files`] — the same entry with a file path where the URI was; the
+//!   bodies are written into the container and the agent `Read`s them. Added
+//!   after `Index` measured 1 retrieval in 9 across three matched runs — see
+//!   [`FILES_PREAMBLE`] for why.
+//!
+//! # Why this is an A/B and not a switch
+//!
+//! Trigger — did the agent reach for the skill when it applied? — is
+//! unmeasurable under `Inline` by construction. Nothing was reached for; the
+//! text was handed over. `skill_use` reports `NotObservable` for exactly that
+//! reason, and it is right to.
+//!
+//! `Index` makes Trigger observable, because retrieval is a recorded
+//! `ReadMcpResourceTool` call. But it can only *cost* Compliance: under
+//! `Inline` the procedure is in front of the model whether or not it noticed
+//! it applied, and under `Index` a missed judgement means the body is never
+//! read at all. Trading a measured axis for an unmeasured regression in
+//! another is not an improvement, so the arm is selected per mission and
+//! recorded on the mission row, and both arms stay runnable.
+//!
+//! # `Index` requires the door, and degrades rather than lying
+//!
+//! An index names a body and tells the agent how to fetch it. If the
+//! `clawmates_skills` MCP server is not reachable from the container, that is
+//! an index of procedures the agent cannot obtain — strictly worse than
+//! `Inline`, and it fails as an agent that ignored its skills rather than as a
+//! missing config. [`resolve`] therefore takes the door's install result and
+//! refuses `Index` without it. This is the same failure the old
+//! `pinned_skills_text` doc comment warned about; what changed is that the
+//! door now exists, not that the warning stopped applying.
+
+/// Where the index tells agents to fetch a skill body from.

+///                                hits a tier, so stepping down often clears it.
+///   -> kimi -> glm               two separately funded accounts. Now an
+///                                Anthropic outage, not just a throttle, is
+///                                survivable.
+///   -> local                     our own GPU. Nothing left to be down.
+///
+/// Every model id here was probed on this deployment 2026-08-09 and answered
+/// 200: the four Anthropic tiers on the subscription, `kimi-k2.7-code` on
+/// api.kimi.com/coding, `glm-4.7` on z.ai, and `ornith-fleet:9b` on the fleet.
+/// Configured is not the same as working — see `preflight`, which re-checks
+/// them at boot, because a link nobody exercises is discovered broken during
+/// the outage it existed for.
+///
+/// The last link runs on our OWN hardware. Every other entry — and every other
+/// link above it — depends on somebody else's account staying funded and
+/// unthrottled; `local:` depends on a GPU in the next room. It is last because
+/// it is the weakest model, and present because a chain whose every link is

 //! gateway, opens `/ws/chat?agent=<alias>`, sends the role+task+context prompt,

 //!
-//! **§15 by construction:** the agents are provisioned tool-free (every
-//! sensitive capability is a gated Clawmates MCP tool — the "door"), so a turn
-//! takes no sandbox-leaving action here. If the gateway nonetheless emits an
-//! `approval_request`, we record it as a **blocked** `GatedAction` and end the
-//! turn — we never auto-approve.
+//! **These agents are NOT tool-free.** That claim stood here for months and is
+//! false — see `docs/TOOL-CALL-ARCHITECTURE.md`. It was inferred from a frame
+//! stream that carried no tool events, and the emptiness has a different cause:
+//! `claude_cli` runs `claude -p --output-format json`, which returns a single
+//! final result object, and the provider hardcodes `tool_calls: Vec::new()`.
+//! The agent calls Claude Code's own tools; the transport discards them.
+//! `--output-format stream-json` emits `tool_use`/`tool_result` blocks —
+//! verified against the deployed Claude Code 2.1.228.
+//!
+//! The door-shaped provider that WOULD make this true (`--mcp-config` +
+//! `--disallowedTools` on the natives) is built and documented in
+//! `agent.config.example.toml`, and is not deployed: mission claws bind to
+//! `claude_cli.default`, which sets none of it.
+//!
+//! If the gateway emits an `approval_request` we still record it as a
+//! **blocked** `GatedAction` and end the turn — we never auto-approve.
