-`OrchestratorCore`, and a real host service needs it reachable over the wire.
-This module is that service — the single privileged host component — reached over
-**HTTP** (the universal transport 0070 chose), mirroring the orchestrator control
-plane's shape (`orchestrator/server.py`): a pure `dispatch()` for socket-free
-testing, wrapped by a thin stdlib `http.server` adapter.

-Only the **signed token** crosses the wire; the server holds the shared HS256
-secret and a real `LaunchBroker` (e.g. `DockerBroker`) and runs the existing
-`verify_request` + `_launch`/`_teardown` path behind the endpoint, so nothing
-free-form ever reaches it. Provenance/schema failures are fail-closed 401s that
-never touch the backend (`LaunchBroker.submit` verifies before acting), and a
-backend launch failure is a 502 the caller must surface — neither takes the
-controller down.
-
-The signed launch token *is* the endpoint's authentication (its provenance is the
-whole point of the JWS), so `/broker` needs no separate caller credential; the
-host controller's own lifecycle endpoints, which do, arrive with the `host`-role
-tokens of the separate `HOST_CONTROLLER` trust domain in a later chunk.
-
-The shared signing secret is the durable **launch-broker `TrustDomain` key**
-(#468/#476): a host-canonical key file minted 0600 on first use, provisioned to
-the orchestrator (signer) and this server (verifier). A backend launcher injects
-it via `$BOT_BOTTLE_LAUNCH_BROKER_KEY`; a host-side dev-harness process reads the
-key file directly. Durability is the point — a restarted orchestrator re-verifies
-against the same key, so re-adoption works.

+# PRD 0082: Authoritative failure boundaries
+
+- **Status:** Draft
+- **Author:** codex
+- **Created:** 2026-07-27
+- **Issue:** #444
+
+## Summary
+
+Make every security- or lifecycle-sensitive snapshot distinguish authoritative
+empty state from unavailable state, and make every destructive or
+resource-consuming boundary revalidate the assumptions it acts on. This
+finishes the focused quality work begun under #444 without broad rewrites:
+cleanup cannot act on stale identities, policy introspection cannot publish a
+fabricated empty policy, gateway servers bound untrusted work, and daemon
+shutdown does not emit uncaught background-thread failures.
+
+## Problem
+
+Several paths are individually fail-closed but compose into unsafe or
+misleading behavior:
+
+1. `cleanup` prepares a plan, waits indefinitely for operator confirmation,
+   then kills stored PIDs and removes stored paths without checking that those
+   identities still describe the same orphan. A PID may be reused or a run
+   directory may become active during the prompt.
+2. The supervisor reuses egress's deny-all fallback for
+   `list-egress-routes`. Deny-all is correct for enforcement, but presenting it
+   as a successful empty route table can cause a later replace-all proposal to
+   discard live routes.
+3. The supervisor and Git HTTP services accept bounded declared body sizes but
+   use blocking reads and unbounded request threads. An untrusted bottle can
+   exhaust the shared gateway with slow or parallel requests.
+4. macOS cleanup enumerates containers and networks independently and treats a
+   failed query as an empty class, so a partial snapshot can still become a
+   destructive plan.
+5. Gateway log-pump threads race stream closure during shutdown and emit
+   uncaught exceptions even when shutdown otherwise succeeds.
+6. Firecracker discovers VMs through whitespace-split `pgrep -a` output.
+   A configured cache path containing spaces can hide a live VM from the
+   snapshot and make its run directory appear orphaned.
+7. Docker cleanup asks compose for its project snapshot in best-effort mode.
+   A transient query failure can therefore become an empty stopped-project
+   set and authorize deletion of associated state directories.
+8. Firecracker artifact downloads and registry publication have no network
+   deadline, so an unresponsive registry can hold setup or release work
+   indefinitely.
+9. Authenticated secret blobs select the unauthenticated legacy decoder when
+   their in-band version prefix is changed, allowing storage tampering to
+   bypass tag verification.
+10. Cleanup executes the entire post-confirmation snapshot rather than the
+    intersection with what the operator saw, and mutation failures are not
+    reflected in the command result.
+
+These are one design problem: state used to authorize deletion, replacement,
+or resource allocation must be authoritative at the point of use.
+
+## Goals / Success Criteria
+
+- Cleanup never signals a PID or recursively deletes a path solely because it
+  appeared in a pre-confirmation snapshot.
+- Firecracker cleanup proves immediately before action that a PID is still the
+  same Firecracker process and that a run directory is still orphaned.
+- Firecracker process discovery reads NUL-delimited argv from `/proc`; paths
+  are never reconstructed from whitespace-delimited process listings.
+- All backend cleanup discovery primitives raise a typed enumeration error on
+  operational failure. No backend may independently continue from a partial
+  snapshot.
+- Shared cleanup control flow lives in the backend layer; concrete backends
+  override resource-specific discovery and validation primitives rather than
+  each implementing a bespoke failure policy.
+- `list-egress-routes` returns an MCP error when attribution or policy
+  resolution is unavailable. A genuine, authoritatively resolved empty policy
+  remains a successful empty list.
+- Supervisor and Git HTTP request bodies have total read deadlines, and each
+  service bounds concurrent request work. Limits apply to authenticated
+  callers because bottles themselves are untrusted.
+- Gateway child-output pumping treats expected stream closure during shutdown
+  as completion while preserving diagnostics for unexpected failures.
+- Artifact pull, existence-check, and publication requests use explicit
+  network deadlines.
+- Persisted secrets accept only the authenticated format. The schema migration
+  intentionally clears legacy rows; local agents are reprovisioned rather
+  than retaining a ciphertext-controlled downgrade path.
+- Cleanup executes only resources present in both the displayed and current
+  authoritative plans, attempts every approved mutation, and returns failure
+  when any mutation does not complete.
+- Unit tests cover PID/path reuse, partial backend enumeration, transient
+  policy resolution failure, slow bodies, concurrency saturation, and stream
+  closure races.
+
+## Non-goals
+
+- Further decomposition solely to reduce module line counts.
+- Replacing gateway stdlib HTTP services with a web framework.
+- Changing egress matching, DLP decisions, proposal semantics, or backend
+  launch behavior beyond the synchronization required for safe cleanup.
+- Making cleanup silently skip uncertain resources. Uncertainty is an
+  operator-visible failure.
+
+## Design
+
+### Shared backend control flow
+
+Follow the backend architecture rule used by gateway attachment: shared
+behavior lives above concrete backends; subclasses provide primitives, not
+control flow.
+
+Cleanup remains previewable, but confirmation authorizes a *new authoritative
+evaluation*, not blind execution of the displayed object. The shared flow:
+
+1. asks each available backend for a preview;
+2. displays the union and asks for confirmation;
+3. refreshes each non-empty backend plan;
+4. validates destructive identities immediately before action;
+5. aborts loudly if the refreshed plan or any identity cannot be proven safe.
+
+Backend-specific primitives define how to identify a resource. Firecracker
+uses process start identity plus canonical config/run paths; container
+backends use authoritative CLI queries and stable resource names/labels.
+
+Container engines expose destructive name-based commands without a portable
+compare-and-delete operation. Cleanup therefore refreshes after confirmation
+and requires every discovery query to succeed, minimizing but not claiming to
+eliminate the final name-reuse race. A future engine-specific stable-ID
+primitive may close that residual window without moving control flow back
+into each backend.
+
+### Enforcement state versus introspection state
+
+Egress enforcement retains its deny-all fallback because uncertainty must not
+grant network access. Supervisor introspection uses a strict resolver path:
+unattributed callers and resolver failures become typed MCP errors, while a
+successfully resolved policy containing zero routes returns `routes: []`.
+
+### Gateway resource boundaries
+
+Both stdlib servers set a per-connection body deadline before reading and use a
+bounded request executor or semaphore. Saturated capacity fails quickly with a
+service-unavailable response. Existing size caps remain independent:
+supervisor proposals retain the 1 MiB cap and Git pack requests retain their
+larger protocol-appropriate cap.
+
+### Shutdown diagnostics
+
+The gateway output pump catches only stream-closure exceptions expected after
+the supervisor closes child pipes. Other I/O failures remain visible and are
+reported through the supervisor's normal diagnostic channel.
+
+## Implementation chunks
+
+1. Existing fail-closed security and backend enumeration fixes.
+2. FastAPI orchestrator transport and bounded control-plane bodies.
+3. Egress request-policy and outbound-DLP pipeline extraction.
+4. Supervisor MCP dispatch extraction.
+5. Shared cleanup refresh/revalidation plus authoritative macOS discovery.
+6. Strict supervisor introspection and bounded supervisor/Git HTTP work.
+7. Gateway shutdown log-pump closure handling.
+8. Lossless Firecracker process identities, authoritative Docker cleanup
+   queries, and bounded Firecracker artifact transfers.
+9. Mandatory authenticated secret storage, shared cleanup-plan intersection
+   and mutation accounting, and contained Git backend process failures.

-# PRD prd-new: Host control server
-
- **Status:** Draft
- **Author:** Claude
- **Created:** 2026-07-26
- **Issue:** #468
-
-## Summary
-
-Promote the in-process launch broker into a standalone **host control
-server**: the single privileged component on the host. Both the CLI and the
-orchestrator drive it over HTTP; it brokers agent launches, owns the
-orchestrator's own lifecycle, and is the sole writer of host-durable state (the
-tamper-evident audit record). This closes the three gaps between today's
-well-formed broker *contract* ([`orchestrator/broker.py`](../../bot_bottle/orchestrator/broker.py))
-and a real out-of-process service — transport, durable provisioned secret,
-and a disciplined op vocabulary — and splits host state by
-owner and lifetime. The prize: **the CLI no longer needs the Docker socket**,
-which is what finally lets a dedicated Gitea runner user drop the
-root-equivalent `docker` group (PRD 0070, "Relationship to other work").
-
-## Problem
-
-Container launches run directly from a short-lived CLI process against the
-Docker socket. That socket is root-equivalent, so every host that launches
-bottles hands root to whoever invokes the CLI — including a CI runner user we
-want to keep unprivileged. PRD 0070 already argues for replacing the fat socket
-with a **thin, structured, auditable** launch broker, and the contract for that
-broker exists and is tested in-process. But it is *only* in-process:
-`LaunchBroker.submit(token)` is a method call from
-`OrchestratorCore.launch_bottle` ([`service.py:116`](../../bot_bottle/orchestrator/service.py)),
-and `DockerBroker` is on no production path — every backend starts the
-orchestrator with `--broker stub` ([`__main__.py:54`](../../bot_bottle/orchestrator/__main__.py)).
-
-Three gaps stand between that scaffold and a host service:
-
-1. **No transport.** `submit` is an in-process call. A real service needs a
-   `BrokerClient` that POSTs the signed token and a host-side HTTP server that
-   verifies and acts.
-2. **The signing secret is ephemeral and self-generated.**
-   [`__main__.py:53`](../../bot_bottle/orchestrator/__main__.py) does
-   `secrets.token_bytes(32)` and hands the *same value* to signer and verifier —
-   viable only because they share a process. A separate daemon needs the secret
-   provisioned out of band and durable across orchestrator restarts.
-3. **The op vocabulary is `launch` / `teardown` only.** Everything else
-   host-privileged still lives in the CLI, so the schema has to grow — carefully,
-   since PRD 0070's security argument rests on "structured requests only, static
-   flags + ids."
-
-Separately, host state has no clear owner. `OrchestratorCore.reconcile` takes
-`live_source_ips` as a parameter *only because the orchestrator cannot see the
-backend* ([`service.py:137`](../../bot_bottle/orchestrator/service.py)); the
-egress traffic log is written to the container's stderr; and there is no durable,
-tamper-evident home for the audit record that survives orchestrator destruction.
-
-## Goals / Success Criteria
-
- A standalone host control server that the CLI and orchestrator reach over
-  **HTTP**, with three entry paths working end to end:
-  - `web console -(iroh)-> orchestrator -(http)-> host controller -> launch`
-  - `cli -(http)-> orchestrator -(http)-> host controller -> launch`
-  - `cli -(http)-> host controller` — start / restart / status of the
-    orchestrator **itself** (the bootstrap/recovery path #391 targets).
- The launch op is expressed as a **signed JWT of static flags + ids only**,
-  verified against a closed schema.
- The signing secret is **provisioned out of band and durable** across
-  orchestrator restarts (a `TrustDomain` per #476, with a key the orchestrator
-  never holds for the host controller's *own* endpoints).
- Host-privileged operations move off the CLI to the control server; **the CLI
-  no longer opens the Docker socket** for bottle operations.
- `Orchestrator.reconcile` no longer takes `live_source_ips` — live-bottle
-  enumeration becomes an internal control-server call.
- Host-durable state lands as an **append-only, hash-chained JSONL** audit log
-  owned solely by the host controller; operational state stays SQLite owned
-  solely by the orchestrator.
-
-## Non-goals
-
- **Removing standing privilege.** This converts on-demand privilege (a CLI the
-  user invokes) into standing privilege (a daemon under launchd/systemd). The
-  win is that the privilege is *narrower* (structured requests vs. a raw socket),
-  not that it disappears. "Always running" is an accepted new property.
- **Asymmetric signing.** We stay HS256 — see Design / "Signing stays
-  symmetric."
- **Integrity against a live compromised orchestrator.** Host-location of the
-  audit log does not buy this: the orchestrator makes the decisions being audited
-  and can forge or omit entries wherever the file lives. An off-box copy is the
-  answer, tracked separately.
- **A single unified DB for all state.** Impossible over a guest-kernel share
-  (SQLite locking is not coherent); state is split by owner and lifetime instead.
- **The generic `SecretProvider` (#355)** and **remote terminal design (#478)** —
-  both ride the same door but are their own work.
-
-## Design
-
-### Topology
-
-The host controller is the sole privileged component. The orchestrator becomes a
-client of it for launches, and the CLI becomes a client of it for *both* bottle
-operations (indirectly, through the orchestrator) and orchestrator lifecycle
-(directly, for bootstrap/recovery — startup can't route through the thing being
-started).
-
-```
-web console ─(iroh)─▶ orchestrator ─┐
-                                    ├─(http, signed JWT)─▶ host controller ─▶ launch
-cli ────────(http)──▶ orchestrator ─┘
-cli ────────(http, bearer)──────────────────────────────▶ host controller   (orchestrator lifecycle)
-```
-
-### Transport: `BrokerClient` + host server
-
-`LaunchBroker.submit(token)` keeps its exact signature and semantics; only the
-*wire* changes. A new `BrokerClient` implements the same submit contract by
-POSTing the signed token to the host controller (stdlib `urllib`, like the
-existing [`orchestrator/client.py`](../../bot_bottle/orchestrator/client.py)),
-and the host controller's launch handler is the existing `verify_request` +
-`_launch`/`_teardown` path, now reached over HTTP instead of a method call. The
-in-process `StubBroker` stays for the dev-harness and tests; `DockerBroker`'s
-`_launch`/`_teardown` bodies move behind the server unchanged. Because the client
-satisfies the same interface `OrchestratorCore` already depends on, the core does
-not change to gain a real backend.
-
-### Signing stays symmetric (HS256)
-
-PRD 0070 nominally specifies asymmetric; the code is HS256 and we keep it.
-Asymmetric matters when the verifier is *less* privileged than the signer — here
-it is the reverse: the host controller (verifier) is strictly more privileged
-than the orchestrator (signer), and a controller that could forge orchestrator
-requests gains nothing, since it is already the component that launches. Staying
-symmetric also honors the no-runtime-deps policy (stdlib has no Ed25519). This
-matches the reasoning already inlined in `broker.py`'s module docstring.
-
-### Replay protection is out of scope (tracked in #494)
-
-Once the launch token travels over a wire, a captured token could be replayed —
-`sign_request` already emits `jti`/`iat` but `verify_request` reads neither, so
-there is no expiry window or `jti` cache today. Enforcing that (an `iat` window +
-a self-trimming `jti` cache) is a pure in-process change that lands independently
-of this work, and it is deferred to **#494** rather than gating the MVP of the
-host control server. Nothing here depends on it; it can merge before or after.
-
-### Op vocabulary and the "ids + static flags" rule (gap 3)
-
-Each op moved off the CLI widens the privileged surface, so growth is governed by
-one explicit rule, enforced in `verify_request`'s schema check:
-
-> A broker op carries **only ids and enumerated static flags** — a bottle id, a
-> pool slot, a **content-addressed** image ref chosen from a fixed set, an op
-> name from a closed vocabulary. Never a free-form path, argv, command, or
-> caller-supplied filesystem location. If an operation cannot be expressed that
-> way, it does not become a broker op.
-
-Operations that fit and move off the CLI (all today in
-`backend/*/consolidated_launch.py`, driven by a short-lived CLI process):
-
-| Op | What it does | Fits the rule because |
-|---|---|---|
-| `launch` / `teardown` | existing | ids + slot + image ref |
-| `orchestrator.ensure_running` | start the infra container | no arguments |
-| `orchestrator.{start,restart,status}` | lifecycle (the #391 path) | no arguments |
-| `list_live` | enumerate running bottles for reconcile | no arguments; returns ids/IPs |
-| `allocate_ip` | `next_free_ip` over `_network_container_ips` | no arguments; returns an IP |
-| `provision_git_gate` | `cp`/`exec` a per-bottle deploy key into the gateway | bottle id + key handle, no path |
-| `reprovision` | `docker exec printenv <ENV_VAR_SECRET>` on a live agent | bottle id + secret *name* |
-
-Image **builds** stay with the orchestrator for v1 (PRD 0070 §Memory: builds run
-control-plane-side; a dedicated slim build unit is later, #468-adjacent), so no
-`build` broker op is added here.
-
-With `list_live` as an internal control-server call, `Orchestrator.reconcile`'s
-`live_source_ips` parameter goes away — the tell PRD 0070 called out that the
-orchestrator couldn't see the backend disappears with it.
-
-### Secret provisioning (gap 2)
-
-The shared HS256 secret becomes a durable, out-of-band artifact via the
-**`TrustDomain`** seam (#476,
-[`trust_domain.py`](../../bot_bottle/trust_domain.py)):
-
- The **launch-broker secret** is a `TrustDomain` whose key
-  (`host_signing_key(<file>)`, minted 0600 on first use, durable under
-  `bot_bottle_root()`) is provisioned to the orchestrator (signer) and the host
-  controller (verifier). Durability across orchestrator restarts is what makes
-  re-adoption work — a restart re-verifies against the same key.
- The **host controller's own lifecycle endpoints** (the direct `cli -> host
-  controller` path) get a **separate** `TrustDomain` key the orchestrator never
-  holds — exactly the second domain #476's PRD reserves. The orchestrator must
-  not be able to mint the credentials used to start and stop it.
-
-This reuses the seam #476 landed rather than re-deriving provisioning per
-backend (the PR #471 bug class).
-
-### One daemon, structurally separate handlers (open decision 1)
-
-The audit writer and the broker live in **one daemon** for install simplicity,
-but with **no shared parsing** and **different credentials per handler**:
-
- the **launch** handler requires the signed launch **JWT** (provenance +
-  un-coercible schema);
- the **audit-append** handler takes a plain **bearer token** and writes to the
-  JSONL log.
-
-This does not defend against orchestrator compromise (it holds both creds) — it
-stops a bug in the boring audit path from reaching the privileged launch path.
-The launcher stays small enough to audit line-by-line, per PRD 0070.
-
-### State ownership: split by owner and lifetime
-
-A single mounted DB is impossible — SQLite locking is not coherent across guest
-kernels over a share, which is why the macOS backend already uses a container-only
-volume (`INFRA_DB_VOLUME`). So state splits three ways (depends on #469, which
-gets `bot-bottle.db` off the data plane first):
-
-| Owner | State | Home | Shape |
-|---|---|---|---|
-| **Orchestrator** | `orchestrator_bottles` registry; `bottled_agent_secrets` (encrypted egress tokens); `supervise_proposals` / `supervise_responses` | volume nothing else mounts (generalizing the macOS design) | **SQLite** — mutable, transactional, queried |
-| **Host controller** | supervise audit entries; egress traffic log (today → container stderr); host-side config | host filesystem, survives orchestrator/volume destruction | **JSONL** — append-only |
-| **Gateway** | none | — | after #469 the data plane holds no DB state |
-
-The historical record is **JSONL, not SQLite**, because it is append-only, never
-updated, never transactionally queried: `O_APPEND` writes are atomic, there is no
-locking protocol to get wrong, hash-chaining for tamper-evidence is cheap, and it
-survives container-runtime volume pruning (the #450 lesson) and stays readable
-without the orchestrator running. Both halves of "the audit record" — supervise
-decisions and the egress traffic log — land in the one place.
-
-The orchestrator is **sole mounter and sole writer** of its SQLite volume; the
-host controller is **sole writer** of the JSONL log, over the authenticated
-audit-append channel.
-
-## Implementation chunks
-
-Ordered, each independently mergeable:
-
-1. **`BrokerClient` + host launch server** over HTTP, reusing `verify_request`
-   and the existing `DockerBroker` bodies. Wire `OrchestratorCore` to a
-   `BrokerClient` behind a flag; keep `StubBroker` for the dev-harness. Closes
-   gap 1.
-2. **Durable secret via `TrustDomain`** — provision the launch-broker key to
-   signer + verifier; add the host controller's own lifecycle `TrustDomain`.
-   Closes gap 2.
-3. **Grow the op vocabulary** one op at a time (`list_live` first — it also
-   removes `reconcile`'s `live_source_ips`), each behind the ids + static-flags
-   rule. Closes gap 3.
-4. **JSONL audit log** — the host-controller-owned, hash-chained historical
-   record with the plain-bearer audit-append handler; redirect the egress traffic
-   log into it.
-5. **Drop the Docker socket from the CLI** once every host-privileged op it used
-   is a broker op — the payoff that unblocks the unprivileged Gitea runner user.
-
-## Open questions
-
-1. **Schema-width rule enforcement.** The "ids + static flags" rule is stated;
-   should `verify_request` reject unknown claim keys outright (strict schema) to
-   keep the surface from drifting? Leaning yes.
-2. **Audit-append back-pressure.** What the audit handler does if the JSONL sink
-   is unavailable (fail-closed vs. buffer) — resolve before shipping chunk 5.
-
-## References

-  implements.

- **#476** ([`prd-new-control-plane-auth-provisioning`](prd-new-control-plane-auth-provisioning.md))

- **#494** — enforce broker replay protection (`iat` window + `jti` cache); split
-  out of this PRD as an independent in-process change.

But inspect also fails on transient daemon/API errors, permission failures, timeouts, or a bad context — destroying a healthy gateway on that guess would tear the network out from under every live bottle. Now the destructive path runs only for the known poison signature (docker's `ParseAddr` error from the malformed `::1/64` IPv6 gateway). The absent case (`No such network`) still just creates; any other inspect failure raises a clear GatewayError without mutating shared state. Adds a regression test asserting a generic inspect error issues neither `docker rm --force` nor `docker network rm` and surfaces the error.

didericis-claude	bd8a146a46	fix(docker): heal a poisoned IPv6 gateway network, not just avoid creating one test / integration-docker (pull_request) Successful in 1m15s Details test / image-input-builds (pull_request) Successful in 1m14s Details lint / lint (push) Successful in 3m28s Details tracker-policy-pr / check-pr (pull_request) Failing after 10m28s Details test / unit (pull_request) Failing after 10m39s Details prd-number-check / require-numbered-prds (pull_request) Failing after 10m45s Details test / coverage (pull_request) Has been skipped Details PR #515 stopped bot-bottle from creating a gateway network with a malformed IPv6 subnet (--ipv6=false), but it can't recover a network that is already poisoned. On a daemon that default-enables IPv6, the fixed-name `bot-bottle-gateway` network gets an `fdd0::/64` subnet whose `::1/64` gateway trips docker's own netip.ParseAddr, so `docker network inspect`/`ls` exit non-zero — poisoning every command that reads networks. Such a network can survive on a shared runner from a pre-fix or concurrent launch. `_ensure_network` never healed it: its migrate/recreate branch only ran when `network inspect` succeeded, but a poisoned network makes inspect fail, so the code fell through to `network create`, which no-ops on "already exists" — leaving the poison in place. The next subnet read then failed with ConsolidatedLaunchError (test_multitenant_isolation), and a bare `docker network ls` failed too (test_orphan_cleanup). Fix, two parts: - gateway.py: when `network inspect` fails for a reason other than "no such network", treat the network as poisoned and force-remove + recreate it IPv4-only. Absent-vs-poisoned is distinguished by the inspect stderr. - test.yml: add an integration-docker preflight that drops the leftover gateway network (and its container) before the suite, so direct `network ls`/`inspect` calls in tests are clean even on a daemon where the in-code heal can't run because inspect itself is what's broken. Adds unit coverage for the poisoned-heal and the absent-create split. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-27 01:23:25 +00:00
