feat: expose stable Python API for programmatic bottle orchestration

Add bot_bottle/api.py with four public functions the orchestrator uses:
start_headless, resume_headless, freeze, and destroy. These let a
ProgrammaticBottleRunner call directly into bot_bottle instead of
shelling out to the CLI; call sites in lifecycle.py stay unchanged.

Key changes:
- BottleSpec gains forge_env field for forge sidecar credentials
- _launch_bottle returns (slug, exit_code) instead of int so start_headless
  can return the slug to callers
- All four API functions convert Die and non-zero exits to BottleError
- 27 new unit tests; existing tests updated for the new return type

+# ADR 0004: Risk-weighted coverage, not a single global target
+
+- **Status:** Accepted
+- **Date:** 2026-06-25
+- **Deciders:** didericis
+
+## Context
+
+bot-bottle is a security tool: it sandboxes agents, scans egress for
+secret exfiltration, strips credentials, and gates git pushes. A latent
+bug in that logic is expensive, so test coverage there genuinely
+matters. But the repo also contains code where coverage is a poor
+signal:
+
+- **Interactive entry-point shells** — `cli/init.py` (a `read_tty_line()`
+  prompt loop) and `cli/tui.py` (a curses picker). Their bodies are I/O;
+  a unit test has to fake the entire terminal conversation, so it
+  inflates the number without asserting behaviour that would otherwise
+  go unchecked.
+- **Subprocess / backend orchestration** — the docker / smolmachines /
+  macos-container backends shell out to `docker`, `container`, `smolvm`.
+  Mock-heavy unit tests here mostly re-assert the argv you already
+  wrote (the test passes whether or not the real teardown works), while
+  many of the missed *branches* are failure paths you cannot provoke
+  against a real daemon on cue.
+
+Chasing a single global percentage (e.g. 90%) pushes the most test
+effort onto the least safety-relevant code — exactly backwards — and
+invites performative tests written to colour a line rather than to catch
+a regression (Goodhart's law).
+
+## Decision
+
+Coverage is **risk-weighted**, measured over the **combined unit +
+integration** suites, with three rules:
+
+1. **Critical modules target ≥ 90%.** The security/logic core —
+   `egress_addon{,_core}.py`, `dlp_detectors.py`, `egress.py`,
+   `manifest*.py`, `git_gate.py`, `git_http_backend.py`, `supervise.py`,
+   `yaml_subset.py`, `bottle_state.py` — is Docker-independent and
+   unit-testable, so it carries the high bar. We ratchet toward 90% as
+   these modules are touched; new gaps in them are not acceptable.
+
+2. **Subprocess/backend orchestration is covered by the integration
+   suite, not omitted.** `scripts/coverage.sh` runs unit + integration
+   under one coverage measurement so these modules are scored where they
+   are actually exercised. They stay *visible* — hiding the code that
+   tears down sandboxes and wires networks is the one place we will not
+   omit.
+
+3. **Interactive entry-point shells are omitted** (`.coveragerc`), with a
+   rationale comment. This is the only sanctioned use of `omit` besides
+   `tests/*`.
+
+The forward-looking guard is a **diff-coverage gate**
+(`scripts/diff_coverage.py`): new/changed executable lines on a branch
+must be ≥ 90% covered. This catches regressions where they are
+introduced without forcing a back-fill crusade through legacy glue. The
+gate skips lines in omitted files (there is no coverage data for them),
+so the omit list cannot launder *new* logic into the dark: anything that
+needs real testing must live outside the interactive shells to be
+scored at all.
+
+The **global percentage is informational**, not a CI gate — it would
+otherwise be hostage to the CI runner's Docker availability and to the
+omit list.
+
+## Consequences
+
+- The number we report (`scripts/coverage.sh`) means "coverage of the
+  code we consider testable, across both suites" — a dip is a real
+  regression in code we control, not noise from added CLI glue.
+- No incentive to write mock-the-mock tests for orchestration to defend
+  a global figure.
+- The omit list needs governance: an entry must be a genuinely
+  interactive shell, justified in the `.coveragerc` comment and here.
+  `cli/init.py` and `cli/tui.py` qualify; backend orchestration does
+  not.
+- CI must run the integration suite under coverage to score the
+  orchestration modules; where the runner lacks Docker those tests skip
+  and their modules read low — accepted, because the *enforced* gates
+  (critical-module standard + diff coverage) are Docker-independent.
+- "We're at N%" is now a curated figure; outsiders should read the
+  policy, not just the badge.
+
+## Links
+
+- PRs #290 (cover the egress adapter), and the coverage-policy PR that
+  introduces this record.
+- `.coveragerc`, `scripts/coverage.sh`, `scripts/diff_coverage.py`.
+- `scripts/critical-modules.txt` — the single source of truth for the
+  core-module list; read by both `scripts/coverage.sh` and the
+  `update-badges.yml` "core coverage" badge so they cannot drift.
+- The README carries a `core coverage` badge (auto-updated from that
+  list) — the headline number, distinct from the informational global
+  `coverage` badge.

+# PRD prd-new: Forge native integration
+
+- **Status:** Draft
+- **Author:** claude
+- **Created:** 2026-06-29
+- **Issue:** #317
+
+## Summary
+
+Add a webhook-driven orchestration layer that lets Gitea issues and PR comments
+drive bot-bottle sessions end-to-end with no operator in the loop for the happy
+path. An issue assigned to a member of the configured agent org and labelled
+with an agent name triggers a headless bottle launch; the bottle processes the
+issue, opens a PR, and interacts with the forge through a **forge sidecar** —
+the agent never touches the Gitea API or its credentials directly. The agent
+calls `signal_done(status, summary)` on the sidecar when a work unit is
+complete; the sidecar relays that to the orchestrator over a queue dir (the same
+pattern as the supervise sidecar), so completion is an unambiguous in-band
+signal rather than a comment the orchestrator has to parse. The orchestrator
+freezes the bottle. Subsequent PR comments rehydrate the frozen bottle. The
+bottle is destroyed when the PR closes.
+
+The forge sidecar is backed by a `Forge` abstract class with per-provider
+implementations (Gitea first), so the agent's prompts and the sidecar protocol
+stay forge-agnostic. The sidecar logs forge operations semantically ("read PR
+description", "posted comment", "signalled done"), giving richer provenance than
+post-hoc egress-byte parsing, and enforces a **read-anywhere / write-scoped**
+permission model: the agent may read for context but may only write to the
+issue and PRs it was assigned.
+
+Run provenance is exposed through a **provenance API** (the sidecar's structured
+operation log plus the run's metadata), not posted back into the forge. We do
+not surface a provenance footer in the PR — the audit record lives behind the
+API where it can be retained and queried, rather than as an editable comment.
+
+The separation of concerns across the two layers: bot-bottle owns the headless
+launch primitives, the forge sidecar + `Forge` abstraction, and forge state.
+`bot-bottle-orchestrator` (separate binary) owns the webhook listener, bottle
+lifecycle loop, and monitoring dashboard; it calls into bot-bottle via
+`./cli.py orchestrate`, a thin wrapper command. This PRD covers bot-bottle's
+side of that contract.
+
+## Problem
+
+Today an operator must open the TUI, select an agent and bottle, confirm the
+preflight, and type prompts interactively. This blocks "issue → PR" automation
+and produces no durable audit record of what the agent did. The security model
+already provides the right isolation and egress controls, and `start --headless`
+(#315) already gives `bot-bottle-orchestrator` a non-interactive launch path.
+The missing pieces are a headless `resume` counterpart for rehydrating frozen
+bottles, a forge-interaction surface the agent uses to read context, post
+comments, and signal completion, and the provenance trail that makes the audit
+story legible to reviewers on every PR.
+
+That forge-interaction surface could be built two ways: (2) give the agent the
+Gitea API directly with cred-proxy injecting the token, or (3) put a forge
+sidecar between the agent and the forge. This PRD takes **option 3**. The
+deciding factors: a sidecar `signal_done` call is an unambiguous completion
+signal where comment-parsing is a correctness risk that surfaces in production;
+the sidecar produces a semantic audit trail rather than HTTP bytes, which is
+load-bearing for provenance (the stated product priority); and the sidecar can
+enforce scope tighter than repo-wide API-key permissions, reducing blast radius
+for a prompt-injected agent. The costs — a second sidecar process per forge run,
+a new failure mode if it crashes, and per-forge implementation cost — are
+accepted as the price of those properties.
+
+## Goals / Success Criteria
+
+1. Headless launch already exists: `./cli.py start <agent> --headless --prompt`
+   (#315) runs non-interactively with no TUI selectors or y/N preflight. This
+   PRD builds on it rather than re-introducing it. The remaining gap is a
+   matching headless `resume` path (`./cli.py resume --headless`), since
+   rehydrating a frozen bottle for a new prompt is required by the freeze /
+   rehydrate loop and `resume` has no non-interactive entry point today.
+2. An issue assigned to a member of the configured org (`FORGE_ORG`, default
+   `bot-bottle`) and labelled `bot-bottle:<agent-name>` is the trigger
+   convention. Org membership is verified via the Gitea API at event time.
+3. Forge-targeted bottles run a **forge sidecar** that exposes a small,
+   forge-agnostic API (comment/issue/PR CRUD plus `signal_done`) over the same
+   queue-dir + HTTP/JSON-RPC machinery as the supervise sidecar. The agent calls
+   the sidecar; it never sees the forge token or forge-specific endpoints.
+4. The sidecar is backed by a `Forge` abstract class. Gitea is the first
+   concrete implementation; adding a forge means a new subclass, not changes to
+   the agent prompt or sidecar protocol. The sidecar enforces a read-anywhere /
+   write-scoped model: writes are limited to the assigned issue and its PRs;
+   reads are unrestricted for context.
+5. The agent calls `signal_done(status, summary)` on the sidecar when a work
+   unit is complete; the sidecar relays it to the orchestrator over a queue dir.
+   This is the done signal — no comment parsing. A watchdog timeout
+   (configurable, default 30 min) causes the orchestrator to treat the run as
+   done-without-self-report if the agent exits without signalling.
+6. Run provenance (agent name, bottle name(s), slug, timing, exit code,
+   gitleaks result, egress summary, and the sidecar's semantic operation log)
+   is available through a provenance API. It is **not** surfaced as a PR footer
+   or any other forge comment.
+7. Forge state (issue → slug, status) is persisted in a local SQLite database
+   under `~/.bot-bottle/` and survives orchestrator restarts.
+8. `./cli.py orchestrate status` lists active forge-managed bottles and their
+   issue/PR URLs.
+9. Unit tests cover: label parsing, org-membership check path, forge state
+   store CRUD (SQLite), headless launch arg construction, forge env var
+   injection, sidecar request dispatch through the `Forge` abstraction,
+   write-scope enforcement (reject writes outside the assigned issue/PRs), and
+   `signal_done` queue relay.
+
+## Non-goals
+
+- Webhook signature verification (HMAC-SHA256). Added as a follow-up.
+- The `bot-bottle-orchestrator` binary itself — this PRD covers bot-bottle's
+  side of the interface only. The orchestrator is a separate project.
+- GitHub or GitLab support.
+- Multiple simultaneous forge bottles per issue.
+- Automatic retry on agent error exit.
+- Bottle destruction on issue close (PR close only; issue close is ambiguous).
+- Concurrent multi-issue handling (one blocking run per orchestrator process).
+- A monitoring dashboard (orchestrator-side concern).
+- Folding `DeployKeyProvisioner` into the `Forge` abstraction. Deploy-key
+  provisioning runs at bottle-provision time on the host; the forge sidecar runs
+  inside the bottle at agent time. The two have different lifecycles and actors,
+  so coupling them into one class is deferred to a follow-up. This PRD only
+  shares the Gitea HTTP client between them.
+
+## Design
+
+### Targeting convention
+
+An issue is forge-targeted when **both** hold:
+
+- At least one assignee is a member of the Gitea org named by `FORGE_ORG`
+  (default `bot-bottle`). Checked via `GET /api/v1/orgs/{org}/members/{user}`.
+- At least one label has the prefix `bot-bottle:`. The suffix names the agent
+  manifest, e.g. `bot-bottle:implementer` → agent `implementer`.
+
+`FORGE_ORG` is read at orchestrate-command startup. It is not embedded in
+manifests or state files; the orchestrator stamps its value into log output for
+auditability.
+
+An optional label `bot-bottle-bottle:<name>` overrides bottle selection. When
+absent the agent's default bottle is used.
+
+### `./cli.py orchestrate` — the thin wrapper
+
+```
+./cli.py orchestrate start  --agent AGENT [--bottle BOTTLE ...] --prompt PROMPT
+                            [--label LABEL] [--backend BACKEND]
+./cli.py orchestrate resume --slug SLUG --prompt PROMPT [--backend BACKEND]
+./cli.py orchestrate status
+```
+
+`orchestrate start` is a thin shim over the already-shipped `start --headless`
+(#315): it forwards agent / bottle / label / prompt and adds the forge-specific
+wiring (`forge_env`, sidecar launch). It does not re-implement headless launch.
+The caller (`bot-bottle-orchestrator`) manages freeze, state, and the forge
+sidecar's done signal around it.
+
+`orchestrate resume` is the shim over the new `resume --headless` (below).
+
+`orchestrate status` prints the forge state table.
+
+### Headless primitives — what exists vs. what's new
+
+Headless **start** already shipped in #315 and this PRD reuses it as-is:
+
+- `./cli.py start <agent> --headless --prompt TEXT` — no TUI selectors, no y/N
+  preflight. Internally `_start_headless()` calls the shared `_launch_bottle()`
+  with `assume_yes=True` and `headless_prompt_text=prompt`.
+- The prompt is delivered through `AgentProvider.headless_prompt(prompt)` —
+  claude `-p`, codex positional, pi `-p`. The orchestrator does **not** hand-roll
+  agent args; it relies on this provider abstraction. (An earlier draft proposed
+  `start_headless` / `attach_agent_headless` helpers that constructed
+  `--no-interactive`/`-p` directly — those are dropped as redundant with, and
+  divergent from, what #315 merged.)
+
+Two additions are needed on top of #315:
+
+**1. A `forge_env` hook on the headless launch path.** The orchestrator needs to
+pass forge context + token through to the forge sidecar launched alongside the
+agent. This is a parameter threaded into `_launch_bottle` (the same core
+`start --headless` already uses), not a parallel launch function. The agent
+process itself does not receive the token.
+
+**2. `resume --headless`** — new in `bot_bottle/cli/resume.py`, mirroring the
+`--headless` flag on `start`:
+
+```
+./cli.py resume <slug> --headless --prompt TEXT
+```
+
+It rehydrates a frozen bottle and runs one headless prompt via the same
+`assume_yes` + `headless_prompt` path, returning the agent's exit code. `resume`
+has no non-interactive entry point today, so this is genuinely new work rather
+than a rename of an existing helper.
+
+### Forge sidecar
+
+Forge-targeted bottles run a forge sidecar alongside the agent, mirroring the
+supervise sidecar: a per-bottle process that exposes an HTTP/JSON-RPC endpoint
+over a Unix socket and relays events to the orchestrator through a queue dir.
+The agent calls the sidecar; the sidecar holds the forge token and makes the
+actual forge API calls. The agent never receives the credential and never sees a
+forge-specific endpoint — swapping Gitea for another forge does not change the
+agent prompt or the sidecar protocol.
+
+The sidecar is configured at launch from the forge context (owner, repo, issue,
+PR) and the token, supplied by the orchestrator — not baked into the agent
+manifest. Because the sidecar owns the token, forge traffic does not need a
+cred-proxy egress route on the agent; the agent's egress policy is unchanged by
+forge targeting.
+
+**Sidecar protocol** (forge-agnostic; each method maps to a `Forge` call):
+
+| Method | Scope | Purpose |
+|---|---|---|
+| `read_issue(number)` | read-anywhere | Read an issue body for context |
+| `read_pr(number)` | read-anywhere | Read a PR (incl. merge state) for context |
+| `read_comments(number)` | read-anywhere | Read a thread for context |
+| `post_comment(number, body)` | write-scoped | Post to the assigned issue/PR |
+| `update_description(number, body)` | write-scoped | Edit the assigned issue/PR body |
+| `signal_done(status, summary)` | — | Relay completion to the orchestrator |
+
+Issues and PRs are distinct domain objects (`Issue` vs `PullRequest`) read
+through distinct methods; a PR carries merge state an issue does not.
+
+**Scope enforcement** is read-anywhere / write-scoped: read methods accept any
+issue/PR number for context; write methods are rejected unless the target is the
+assigned issue or one of its PRs. This is tighter than Gitea's repo-wide API-key
+permissions and bounds the blast radius of a prompt-injected agent. Rejections
+are logged semantically (operation, target, reason) so the audit trail records
+attempted out-of-scope writes, not just allowed ones.
+
+**Semantic audit**: every sidecar call is logged as a structured operation
+("read PR #318 description", "posted comment to #317", "signalled done:
+success") rather than as opaque HTTP bytes. This log feeds provenance directly,
+with no post-hoc egress-log parsing.
+
+### `Forge` abstraction — `bot_bottle/contrib/forge/`
+
+The sidecar dispatches to a `Forge` abstract class. Each provider implements the
+operations behind the sidecar protocol:
+
+```python
+class Forge(abc.ABC):
+    @abc.abstractmethod
+    def read_issue(self, number: int) -> Issue: ...
+    @abc.abstractmethod
+    def read_pr(self, number: int) -> PullRequest: ...
+    @abc.abstractmethod
+    def read_comments(self, number: int) -> list[Comment]: ...
+    @abc.abstractmethod
+    def post_comment(self, number: int, body: str) -> None: ...
+    @abc.abstractmethod
+    def update_description(self, number: int, body: str) -> None: ...
+    @abc.abstractmethod
+    def is_org_member(self, org: str, username: str) -> bool: ...
+    @abc.abstractmethod
+    def get_pr_for_issue(self, number: int) -> int | None: ...
+    @abc.abstractmethod
+    def is_pr_open(self, number: int) -> bool: ...
+```
+
+`Issue` and `PullRequest` are separate frozen dataclasses — a PR adds `merged`.
+`ScopedForge` wraps a concrete `Forge` to enforce the read-anywhere /
+write-scoped model (`post_comment` / `update_description` raise `ForgeScopeError`
+outside the assigned issue and PRs).
+
+`GiteaForge` is the first and only concrete implementation in this PRD. It wraps
+the Gitea HTTP client (below). Adding GitHub or GitLab later is a new subclass;
+the sidecar, protocol, and agent prompt are untouched.
+
+> **Deferred:** `DeployKeyProvisioner` is *not* folded into `Forge` here.
+> Deploy-key provisioning runs on the host at provision time; the sidecar runs
+> in the bottle at agent time. They have different lifecycles and actors, so a
+> shared abstract base would couple two unrelated auth contexts. For now they
+> only share the Gitea HTTP client; a later PRD can revisit unification.
+
+### Forge env vars
+
+The orchestrator passes forge context to the **sidecar** (not the agent) at
+launch. The agent does not need owner/repo/issue env vars to construct API
+calls, since it only names issue/PR numbers to the sidecar:
+
+| Var | Example | Purpose |
+|---|---|---|
+| `FORGE_GITEA_API` | `https://gitea.dideric.is/api/v1` | Base URL the sidecar calls |
+| `FORGE_OWNER` | `didericis` | Repo owner |
+| `FORGE_REPO` | `bot-bottle` | Repo name |
+| `FORGE_ISSUE_NUMBER` | `317` | Assigned issue (defines write scope) |
+| `FORGE_PR_NUMBER` | `318` | Assigned PR (empty until PR exists) |
+
+The agent's forge-specific prompt instructs it to call `signal_done` on the
+sidecar when a work unit is complete, and to use the sidecar for any
+comment/description writes. The instruction is forge-agnostic and is part of the
+forge prompt overlay, not the base agent manifest, so non-forge runs are
+unaffected.
+
+### Done signal and watchdog
+
+The agent calls `signal_done(status, summary)` on the sidecar when it finishes a
+work unit. The sidecar writes the event to its queue dir; the orchestrator reads
+it and:
+
+1. Reads the forge state for `(owner, repo, issue_number)`.
+2. If `status == "running"`, treats the event as the done signal: freezes the
+   bottle and sets `status = "frozen"`. Provenance is recorded via the
+   provenance API — no comment is posted to the forge.
+
+Because completion is an explicit `signal_done` call, the orchestrator does not
+parse comment text to detect "done", and intermediate comments the agent posts
+mid-run cannot be mistaken for completion.
+
+**Watchdog**: the orchestrator tracks `last_checkin_at` in forge state, updated
+on each sidecar event. A background thread wakes every minute. If
+`now - last_checkin_at > FORGE_WATCHDOG_TIMEOUT` (default 30 min, configurable
+via env) and `status == "running"`, the orchestrator treats the run as
+done-without-self-report and freezes the bottle, flagging the run as incomplete
+in the provenance record.
+
+**Sidecar-death failure mode**: if the forge sidecar crashes mid-run the agent
+loses forge access while the bottle is otherwise healthy. The orchestrator
+detects a dead sidecar (socket/queue gone) the same way it detects a stalled
+agent and falls back to the watchdog path.
+
+### Forge state — `bot_bottle/contrib/gitea/forge_state.py`
+
+State is stored in a local SQLite database at `~/.bot-bottle/bot-bottle.db`.
+Access goes through a thin CRUD interface, `ForgeStateStore`, so the storage
+location/engine can be swapped without touching callers. `SqliteForgeStateStore`
+is the first implementation.
+
+The `forge_state` table is keyed by `(owner, repo, issue_number)` and carries:
+`slug`, `agent_name`, `bottle_names` (JSON), `backend_name`, `agent_git_user`,
+`pr_number` (nullable), `status`, `last_checkin_at`.
+
+`status`: `"running"` | `"frozen"` | `"destroyed"`.
+
+Store interface:
+
+```python
+class ForgeStateStore(abc.ABC):
+    def upsert(self, state: ForgeState) -> None: ...
+    def get(self, owner: str, repo: str, issue_number: int) -> ForgeState | None: ...
+    def delete(self, owner: str, repo: str, issue_number: int) -> None: ...
+    def all(self) -> list[ForgeState]: ...
+
+class SqliteForgeStateStore(ForgeStateStore):
+    def __init__(self, db_path: Path | None = None) -> None: ...
+```
+
+`upsert` uses `INSERT OR REPLACE` so a re-run for the same issue overwrites in
+place. The schema is created on first open.
+
+### Provenance API
+
+Run provenance — agent, bottle(s), slug, timing, exit code, gitleaks result,
+egress summary, watchdog-fired flag, and the sidecar's semantic operation log —
+is exposed through a **provenance API**, not posted into the forge. There is no
+provenance footer or run-summary comment.
+
+The rationale (per the monetization positioning): a PR comment is mutable by any
+maintainer, unsigned, and per-PR, so it is worthless as an audit record and
+invites false trust. The authoritative record therefore lives behind the API,
+where it can be retained, queried, and (eventually) signed. Whether any
+projection of it ever appears in the forge is a separate, out-of-scope decision;
+this PR does not build one.
+
+The API surface itself (schema, transport, signing, retention) is **out of scope
+for this PRD** and belongs with the orchestrator / control-plane work. bot-bottle
+here only produces the raw material: the sidecar's semantic operation log and the
+run metadata the orchestrator collects.
+
+### Gitea HTTP client — `bot_bottle/contrib/gitea/client.py`
+
+`GiteaForge` (and the existing `GiteaDeployKeyProvisioner`) share one thin HTTP
+client. Unlike the option-2 design, the token is held by the sidecar process and
+passed to the client directly — there is no agent-side cred-proxy route to
+inject it, because the agent never makes forge calls.
+
+```python
+class GiteaClient:
+    def __init__(self, *, api_url: str, owner: str, repo: str, token: str) -> None: ...
+    def is_org_member(self, org: str, username: str) -> bool: ...
+    def get_issue(self, number: int) -> dict: ...
+    def get_comments(self, number: int) -> list[dict]: ...
+    def post_comment(self, number: int, body: str) -> None: ...
+    def patch_issue_body(self, number: int, body: str) -> None: ...
+    def get_pull(self, number: int) -> dict: ...
+```
+
+`GiteaForge` adapts this client to the `Forge` surface (mapping raw JSON to
+`Issue` / `PullRequest` / `Comment`). Sharing only the HTTP client (not an
+abstract base) is the deliberate boundary between the sidecar and the deploy-key
+provisioner — see the deferral note under the `Forge` abstraction.
+
+### Implementation chunks
+
+1. **Headless additions on top of #315** — thread a `forge_env` parameter into
+   the existing `_launch_bottle` core (the one `start --headless` already uses);
+   add a `--headless` path to `cli/resume.py` reusing `assume_yes` +
+   `headless_prompt`. No new `start_headless`/`attach_agent_headless` helpers.
+   Tests: `forge_env` reaches the sidecar/`guest_env`; `resume --headless` skips
+   the TUI and y/N preflight and returns the agent exit code.
+
+2. **Forge state** — `contrib/gitea/forge_state.py`: `ForgeState` dataclass,
+   `ForgeStateStore` CRUD interface, `SqliteForgeStateStore`. Tests: round-trip,
+   missing → None, `INSERT OR REPLACE` upsert, delete idempotent, `all()`
+   ordering, persistence across store instances.
+
+3. **`Forge` abstraction + Gitea client** — `contrib/forge/base.py` (`Forge`
+   ABC, `ScopedForge`, `Issue` / `PullRequest` / `Comment`) and
+   `contrib/gitea/client.py` + `GiteaForge`: `is_org_member`, `read_issue`,
+   `read_pr`, `read_comments`, `post_comment`, `update_description`,
+   `get_pr_for_issue`, `is_pr_open`. Tests: mock `urllib.request.urlopen`,
+   assert payloads and 404-as-false for membership; `ScopedForge` write-scope
+   enforcement.
+
+4. **Forge sidecar** — sidecar process exposing the protocol over a Unix socket,
+   queue-dir relay, write-scope enforcement, semantic op log, `signal_done`.
+   Reuses the supervise sidecar bundle machinery. Tests: dispatch each method to
+   the `Forge`, reject out-of-scope writes, `signal_done` writes a queue event,
+   scope-rejection is logged.
+
+5. **`./cli.py orchestrate`** — `cli/orchestrate.py` with `start`, `resume`,
+   `status` subcommands wired into `cli.py`; `start` launches the forge sidecar
+   alongside the agent for forge-targeted runs. Tests: arg parsing, `start`
+   delegates to `start --headless`, `resume` delegates to `resume --headless`.
+
+## Provenance
+
+Run provenance is captured (sidecar semantic operation log + run metadata) and
+exposed through a provenance API. It is deliberately **not** surfaced in the
+forge — no footer, no run-summary comment. A mutable, unsigned PR comment is not
+an audit record; the authoritative record lives behind the API where it can be
+retained and signed. The `watchdog_fired` flag marks runs where the agent did
+not self-report completion so consumers of the API know the record may be
+incomplete.
+
+The provenance API's schema, transport, signing, and retention are out of scope
+for this PRD (control-plane work); bot-bottle here produces the raw material
+only.

+"""Unit: EgressAddon request/response decision flow (issue #286).
+
+`egress_addon.py` is the sidecar-only mitmproxy adapter that wires the
+host-importable decision logic in `egress_addon_core` into mitmproxy's
+request/response hooks. The core logic is exercised directly by
+`test_egress_addon_core.py`; the redaction logging by
+`test_egress_addon_log_redaction.py`. This file covers the adapter glue
+itself — `request()`, `response()`, `websocket_message()`, introspection,
+auth injection, git push/fetch blocking and the outbound-DLP policy
+branches — so `bot_bottle/egress_addon.py` no longer has to be omitted
+from coverage.
+
+mitmproxy is not installed on the host, so we pre-populate `sys.modules`
+with the minimum stubs needed to import the adapter (a `mitmproxy.http`
+module exposing a `Response` with `.make`, plus the flat
+`egress_addon_core` name the sidecar uses)."""
