Provision an Apple Silicon host with the `container` CLI on `PATH` and `container system status` running, then register the runner in **host mode** (not docker mode) with the `macos` label — `brew install gitea-runner` (the `act_runner` rename). Give it a Python ≥ 3.11 with `coverage` importable on the launchd service's `PATH` (a launchd service doesn't inherit your shell profile, so pin `node` and the Python env explicitly). The job is **advisory** — `workflow_dispatch` (manual) only, never triggered by push or PR — since a single laptop that sleeps/roams must not block merges or churn on every push to main; its coverage doesn't feed the gate.

 # CI
 
-## Required pull-request gate
+The test workflow lives at [`.gitea/workflows/test.yml`](../.gitea/workflows/test.yml).
+It runs the unit suite plus one integration job per backend
+(`integration-docker`, `integration-firecracker`, `integration-macos`) on:
 
-[`.gitea/workflows/test.yml`](../.gitea/workflows/test.yml) runs the unit
-suite, Docker integration suite, combined coverage report, and diff-coverage
-gate when tested package/build inputs change on a pull request or on `main`.
+- every push to a branch with an open pull request, and
+- every push to `main`.
 
-The Docker job preflights the backend before discovery. Gitea's `act_runner`
-runs the job in a container with the host Docker socket, so the test process
-reaches control-plane siblings through the job's Docker network and uses named
-Docker volumes for orchestrator/CA state the host daemon must mount. The
-orchestrator runs the package baked into the image built from the checkout; it
-does not bind the job container's invisible workspace into a sibling container.
-Docker integration jobs share fixed singleton names, so required and manual
-runs use one non-cancelling concurrency group. The shared agent/gateway network
-has an explicit subnet, which Docker requires for the pinned source IPs used as
-the isolation/attribution key.
+`integration-macos` is the exception: it is **advisory**, running only on
+`workflow_dispatch` (manual dispatch), never on push or pull requests. It targets the
+Apple Container backend on a self-hosted macOS runner (label `macos`,
+registered in host mode — Apple Container can't run in a Linux container, so it
+can't reuse the `kvm` runner). A single non-redundant laptop must not be able
+to block a PR merge, so the job stays out of the `coverage` job's `needs` and
+its coverage never feeds the diff-coverage gate. Because the infra container is
+a singleton (`bot-bottle-mac-infra`), the job declares a `concurrency` group
+and tears the container down on exit; keep runner concurrency at 1. See the
+README "macOS Apple Container" CI note for runner provisioning.
 
-`scripts.unittest_gate` enforces the Docker job's contract: all 22 integration
-tests must execute and none may skip. This includes the real gateway-image,
-control-plane authentication, multitenant policy/token isolation,
-sandbox-escape, and orphan-network tests. Backend skip decorators remain useful
-for local runs, but the CI preflight plus execution-count gate prevents a
-missing backend or runner-topology regression from becoming a green job.
+Each integration job selects its backend via `BOT_BOTTLE_BACKEND` and
+runs a **preflight** (`./cli.py backend status --backend=<name>`) that
+prints a clear per-check readiness summary and fails the job when the
+backend is missing — so absent infrastructure is visible at the job level
+rather than hidden among per-test `unittest.skip` lines. The skip guards in
+[`tests/_backend.py`](../tests/_backend.py) gate on the same readiness
+check (`bot_bottle.backend.has_backend`): backend-agnostic tests use
+`skip_unless_selected_backend_available()` and run through whichever
+backend is selected (checking, e.g., Linux + `/dev/kvm` for Firecracker
+rather than unrelated Docker availability); Docker-implementation tests use
+`skip_unless_backend("docker")` and no-op under a non-Docker run.
 
-Combined unit + Docker coverage is informational globally. Two focused gates
-are enforced:
+A small subset of integration tests skip when running specifically
+under Gitea Actions (`GITEA_ACTIONS=true`), because `act_runner` runs
+the job inside a container with the host's `/var/run/docker.sock`
+mounted in. That topology breaks two assumptions those tests make:
 
-- changed executable Python lines must be at least 90% covered; and
-- the validated critical security/logic core must remain at least 90% covered.
+- networks created via the host daemon aren't always visible to a
+  same-process `docker network ls` call from inside the job container,
+  and
+- ports published by sibling containers land on the host's loopback,
+  not on the job container's `127.0.0.1` — so HTTP probes against
+  `http://127.0.0.1:<host_port>` from inside the job time out.
 
-## Privileged pre-release matrix
-
-[`.gitea/workflows/pre-release-test.yml`](../.gitea/workflows/pre-release-test.yml)
-is manually dispatched before a release. It repeats unit and Docker integration
-coverage, then runs:
-
-- Firecracker integration on the self-hosted `kvm` runner; and
-- advisory Apple Container integration on the self-hosted `macos` runner.
-
-These privileged host-mode runners never execute unreviewed pull-request code
-automatically. Firecracker coverage is combined in the manual pre-release
-report; macOS reports advisory coverage in its own job. The macOS infra
-container is a singleton, so its job uses a concurrency group and always tears
-the service down.
-
-## Scheduled canary
-
-[`.gitea/workflows/canaries.yml`](../.gitea/workflows/canaries.yml) runs weekly
-and on manual dispatch. It verifies the pinned gitleaks release URL, checksum,
-archive shape, and executable. The same unittest execution gate requires at
-least one executed canary and rejects skips.
+The affected tests (`test_orphan_cleanup.test_create_and_remove`,
+`test_gateway_image.TestGatewayImage`) still run
+locally where the test process and Docker daemon share a host.
+Making them work in CI is a follow-up: either re-write them to
+discover container IPs via `docker inspect`, or reconfigure the
+runner with host networking.

-# Design workflow
-
-How bot-bottle turns discussion into canonical design and then into
-implementation without leaving the repository's architecture scattered across
-issue and review threads.
-
-The goal is not more documentation. The goal is one discoverable current answer
-for every load-bearing design question.
-
-## Sources of truth
-
-Design artifacts have different jobs:
-
-| Artifact | Authority |
-|---|---|
-| Decision records | Stable system-wide boundaries, policies, and invariants |
-| PRDs | The current design for a feature |
-| Research notes | Evidence and tradeoff analysis; informative, not normative |
-| Issues | Work tracking, open questions, and discussion |
-| Pull-request comments | Review history; never the final home of a design decision |
-
-When a discussion changes the design, update the relevant PRD or decision
-record before treating the discussion as resolved. A comment may explain why a
-decision changed, but future implementers must not need to reconstruct the
-decision from a thread.
-
-Avoid duplicating the same rule in several canonical documents. Prefer one
-canonical statement and links from dependent documents.
-
-## Choosing the canonical artifact
-
-Use a PRD when the decision describes a feature: its behavior, scope, success
-criteria, trust model, implementation slices, and tests.
-
-Use a decision record when the choice is broader than one feature or will
-constrain several future features. Examples include state ownership, credential
-boundaries, compatibility policy, and what the project does or does not claim
-as a security guarantee.
-
-Use a research note when the conclusion depends on comparing external systems,
-protocols, or approaches. Promote any resulting project decision into a PRD or
-decision record.
-
-## From discussion to implementation
-
-### 1. Open the design discussion
-
-An issue may start with incomplete requirements. Record:
-
-- the problem and desired outcome;
-- known security or compatibility constraints;
-- the current owner of affected state and credentials;
-- related PRDs, decisions, issues, and pull requests;
-- open questions that would materially change the implementation.
-
-Do not disguise an unresolved trust-boundary or state-ownership decision as an
-implementation detail.
-
-### 2. Draft or update the canonical design
-
-Before substantial implementation, write the feature PRD and update any
-system-wide decision it changes.
-
-An active design should make these relationships visible near its top:
-
-```markdown
-Status: Draft | Active | Superseded | Retargeted
-Depends on: #...
-Supersedes: ...
-```
-
-Record dependencies only on the dependent document. Do not maintain reverse
-`Blocks` lists that can drift as dependent work changes.
-
-For security-sensitive work, state:
-
-- the exact guarantee and explicit non-guarantees;
-- trusted and untrusted components;
-- who creates each identity or attribution field;
-- who owns durable state;
-- failure and recovery behavior;
-- how the design is tested at its boundaries.
-
-### 3. Resolve review into the repository
-
-When review settles a design-changing question:
-
-1. Update the canonical document in the same pull request.
-2. Mark conflicting documents Superseded or Retargeted, or update them.
-3. Add or adjust dependency links.
-4. Leave a concise resolution comment linking to the canonical change.
-
-A useful resolution comment is:
-
-```text
-Resolution: <what was decided>
-Canonicalized in: <document/section/commit>
-Supersedes: <older statement, if any>
-Follow-up: <remaining implementation or question>
-```
-
-The resolution is incomplete until the repository reflects it.
-
-### 4. Check design readiness
-
-Implementation may begin when:
-
-- the PRD's material trust, ownership, and compatibility questions are settled;
-- dependencies and blockers are explicit;
-- the design agrees with current architecture and decision records;
-- superseded documents are marked or updated;
-- success criteria and boundary tests are concrete;
-- remaining open questions can be answered during implementation without
-  changing the feature's guarantee or component ownership.
-
-Small exploratory spikes may happen earlier. A spike proves feasibility; it does
-not establish a production contract or silently settle the design.
-
-### 5. Implement in ordered slices
-
-Prefer small, independently reviewable slices after the parent design is
-accepted. Record the dependency chain explicitly.
-
-Parallel work is safe when slices do not compete for the same unsettled
-interface or ownership boundary. If a foundational change will alter the
-transport, schema, state owner, or trust domain used by another slice, land the
-foundation first.
-
-An implementation pull request should identify:
-
-- the PRD or decision it implements;
-- the implementation chunk;
-- its base and blockers;
-- any design deviation discovered during implementation.
-
-If implementation reveals a load-bearing design change, pause that slice and
-update the canonical design. Do not let the code and review thread become an
-undocumented replacement for the PRD.
-
-## Dependency and staleness management
-
-### Dependency direction
-
-Write dependencies in terms of contracts, not chronology:
-
-```text
-credential provisioning contract
-  -> host-controller authentication
-    -> privileged host operations
-```
-
-If only part of a feature is blocked, say so. For example, a manifest parser may
-proceed while that feature's durable audit-storage chunk waits for the canonical
-audit schema.
-
-### Superseding documents
-
-Do not silently edit history to make an old design appear to have always said
-the new thing. Preserve the rationale, but make current status unmistakable:
-
-```markdown
-Status: Superseded
-Superseded by: <document>
-Reason: <one paragraph>
-```
-
-If part of a PRD remains valid, mark it Retargeted and identify which scope moved
-elsewhere.
-
-Add a short supersession note near the top explaining what changed, why the old
-design is no longer current, and where the current design lives. For a research
-note whose original analysis remains useful, preserve that analysis and append
-a dated addendum with the newer finding instead of rewriting the note as though
-it had always reached the new conclusion.
-
-### Architecture sweeps
-
-After a foundational change, do a targeted architecture sweep before building
-more features on it:
-
-1. Identify the concepts the change affects, such as `bot-bottle.db`, host
-   controller, orchestrator, audit ownership, or signing key.
-2. Search active PRDs, decisions, and open issues for those concepts.
-3. Update or supersede contradictory statements.
-4. Refresh dependency links and the current architecture summary.
-5. Confirm stacked implementation branches still have the correct base.
-
-This is a milestone activity, not a recurring documentation ceremony.
-
-## Pull-request checklist
-
-Use the relevant items in design and implementation pull requests:
-
-- [ ] The canonical PRD or decision is linked.
-- [ ] Design-changing review decisions are reflected in-repo.
-- [ ] Dependencies and blockers are explicit.
-- [ ] State, credential, and trust ownership agree with current architecture.
-- [ ] Superseded or retargeted documents are marked.
-- [ ] Security guarantees and non-guarantees are precise.
-- [ ] Open questions do not change the promised guarantee or ownership model.
-- [ ] Implementation deviations updated the canonical design.
-
-## Lightweight maintenance
-
-Automation should enforce document shape, not pretend to understand
-architecture. Useful checks include:
-
-- active PRDs contain status and dependency metadata;
-- superseded PRDs link to their replacement;
-- referenced documents and issues exist;
-- implementation pull requests identify their PRD and chunk;
-- document filenames and lifecycle states follow repository conventions.
-
-Human review remains responsible for detecting conflicting guarantees or
-ownership claims.
-
-The durable rule is simple: **discussion discovers the decision; the repository
-records it; implementation follows it.**
