docs(prd): add PRD for egress control plane

Out-of-band egress enforcement & cost-control plane: meter token usage
at the egress proxy, evaluate budgets with agent→bottle→parent→global
precedence, and force cutoff/freeze/kill without the agent in the loop.
Introduces a host-level SQLite ledger behind a thin repository API and a
host-only TUI dashboard. Closes the design discussion on #251.

+# 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 0065: Multi-parent `extends:` for bottles
+
+- **Status:** Active
+- **Author:** didericis
+- **Created:** 2026-06-25
+- **Issue:** #268
+- **Extends:** PRD 0025 (`0025-bottle-extends.md`)
+
+## Summary
+
+Allow a bottle's `extends:` field to accept either a single bottle name (existing
+behavior) or a list of bottle names (new). Multiple parents are resolved
+independently and folded left-to-right into a single effective parent before the
+child is merged on top. This lets orthogonal concerns (base env, networking/egress,
+agent provider) live in separate bottles and be composed without forcing them into a
+linear chain.
+
+## Problem
+
+PRD 0025 shipped single-parent `extends:` and listed "No multi-parent inheritance"
+as a non-goal. In practice, users want to compose multiple orthogonal bottles — a
+base environment, a networking profile, and an agent-provider override — without
+creating a three-level linear chain that couples unrelated parents to each other.
+The linear chain workaround has two problems:
+
+1. **Ordering constraint.** `networking extends base` works, but then
+   `agent extends networking` can't also pick up `base` without going through
+   `networking`, coupling two unrelated concerns.
+
+2. **Quadratic duplication.** N orthogonal bottles require O(N²) chain variants
+   (one chain per permutation of applied concerns).
+
+Multi-parent `extends:` removes both constraints: each orthogonal concern stays in
+its own bottle, and the child bottle is the only place that names the combination.
+
+## Goals / Success Criteria
+
+- `extends:` accepts a list of strings in addition to a plain string.
+- Backward compat: existing single-string `extends:` is unchanged.
+- Parents are resolved left-to-right; later entries win on conflict.
+- Child wins over all parents (unchanged from PRD 0025).
+- Cycle detection covers multi-parent graphs, not just linear chains.
+- Diamond inheritance: a shared ancestor is resolved once (via the existing cache).
+- Invalid list entries (non-string, undefined bottle, self-reference) die at parse
+  with clear messages.
+- `manifest_loader.py`'s `load_bottle_chain_from_dir` enqueues all parents from a
+  list `extends:` so the resolver sees every bottle in the graph.
+
+## Non-goals
+
+- No change to the agent-vs-bottle trust boundary (PRD 0025 "Alternatives
+  considered" option 2 stays rejected).
+- No MRO / C3 linearization. Left-to-right fold is sufficient for the expected use
+  cases.
+- No preflight display of per-field provenance across multiple parents (same open
+  question as PRD 0025; remains a follow-up).
+
+## Design
+
+### Schema
+
+`extends:` now accepts either form:
+
+```yaml
+# single parent (unchanged)
+extends: base
+
+# multiple parents (new)
+extends: [base, networking]
+```
+
+Both forms are normalized to a list internally. A list with one element behaves
+identically to the string form.
+
+### Merge rules for multi-parent fold
+
+Parents are folded pairwise left-to-right before the child merge. For each step in
+the fold, the "earlier" bottle is the running accumulator and the "later" bottle is
+the next parent. Rules per field:
+
+| Field              | Fold rule                                                    |
+|--------------------|--------------------------------------------------------------|
+| `env`              | dict merge; later wins on key collision                      |
+| `git-gate.user`    | per-field overlay; later's non-empty fields win              |
+| `git-gate.repos`   | union by name; for same-name entries, later wins per-field   |
+| `egress.routes`    | concatenate (earlier first, later appended)                  |
+| `egress.log`       | later wins (last-wins)                                       |
+| `agent_provider`   | later wins (last-wins)                                       |
+| `supervise`        | later wins (last-wins)                                       |
+
+After the fold, the combined parent is merged against the child using the existing
+PRD 0025 rules (child always wins). The child's `egress.routes` appends to the
+combined parent's concatenated routes; `validate_egress_routes` runs once on the
+final merged set and catches duplicate hosts.
+
+### Algorithm
+
+```
+extends: [p1, p2, p3]
+
+fold:
+  combined = resolve(p1)
+  combined = fold_two(combined, resolve(p2))
+  combined = fold_two(combined, resolve(p3))
+
+merge:
+  result = _merge_bottles(combined, child_raw, name)
+```
+
+`fold_two(earlier, later)` applies the rules in the table above. Cycle detection
+(the `seen` tuple) is passed to each parent resolution call unchanged — if any
+parent's chain circles back to the current bottle, it is caught. The `cache` dict
+ensures a shared ancestor is only resolved once across all parents.
+
+### Error cases
+
+| Condition                              | Error message shape                                              |
+|----------------------------------------|------------------------------------------------------------------|
+| `extends` is not a string or list      | `extends must be a string or list of strings (was <type>)`       |
+| A list entry is not a string           | `extends[<i>] must be a string (was <type>)`                     |
+| A list entry names an undefined bottle | `extends '<name>' which is not defined. Available bottles: ...`  |
+| A list entry is the bottle itself      | `extends itself; remove the self-reference`                      |
+| Cycle through any parent edge          | `is in an extends cycle: <chain>`                                |
+
+## Implementation
+
+### `bot_bottle/manifest_extends.py`
+
+- `_resolve_one_bottle`: accept `str | list[str]` for `extends`; normalize to list;
+  validate each entry; for a single-entry list fall through to the existing
+  single-parent path; for multiple entries call `_fold_parents` then
+  `_merge_bottles`.
+- `_fold_parents(parent_names, raws, cache, repos_cache, seen)`: resolve each
+  parent and fold pairwise left-to-right; return `(effective_bottle,
+  effective_repos_raw)`.
+- `_fold_two_bottles(earlier, earlier_repos_raw, later, later_repos_raw)`: apply
+  the fold rules above; return `(folded_bottle, folded_repos_raw)`.
+
+### `bot_bottle/manifest_loader.py`
+
+- `load_bottle_chain_from_dir`: when `extends` is a list, enqueue all parent names
+  for loading (previously only `isinstance(parent, str)` was handled).
+
+### `tests/unit/test_manifest_extends.py`
+
+- `TestExtendsErrors.test_non_string_extends_dies`: update to use an integer
+  `extends` value (a list is now valid).
+- New class `TestExtendsMultiParent` covering all cases listed in the issue.
+
+## Testing strategy
+
+Unit tests via `ManifestIndex.from_json_obj` (same resolver surface used by all
+paths). No integration test changes needed — downstream code consumes the already-
+merged bottle and is unchanged.
+
+Test cases:
+- Two-parent list: env union, egress routes concat, git repos union
+- Last-parent-wins on scalar (supervise, agent_provider)
+- Child wins over all parents on conflict
+- Diamond: two parents share an ancestor; ancestor resolved once
+- Single-element list: identical to string form
+- Non-string extends value → ManifestError
+- Non-string list entry → ManifestError
+- Undefined bottle in list → ManifestError
+- Self-reference in list → ManifestError
+- Cycle through multi-parent edge → ManifestError

+
+- **Status:** Active
+- **Author:** claude

+
+## Summary
+
+Agents and bottles are two separate concerns: agents carry a system prompt and
+skills; bottles carry infrastructure configuration (egress, git-gate, env,
+agent provider). Today an agent's manifest file hard-codes a single `bottle:`
+reference, which prevents the same agent prompt from being reused across
+projects that need different bottle configurations. This PRD decouples them: at
+launch time, after choosing the agent, the operator picks an ordered list of
+bottles via a multi-select picker. The selected bottles are merged in order
+(later entries override earlier ones) to produce the effective bottle for the
+session.
+
+## Problem
+
+The current `bottle: <name>` field on an agent manifest file binds the agent
+permanently to one bottle. To use the same system prompt with a different bottle
+(e.g. `claude-implementer` at home vs. at a client site that needs a different
+egress policy), the operator must duplicate the agent file and change the
+`bottle:` field. Duplicate agent files drift out of sync.
+
+## Goals / Success Criteria
+
+1. `bottle:` in an agent's frontmatter becomes optional. Existing manifests with
+   `bottle:` continue to work unchanged (backward compat).
+2. After selecting an agent (via the existing single-select picker), a new
+   multi-select bottle picker appears showing all available bottles.
+3. The multi-select picker pre-populates with the agent's `bottle:` value when
+   present.
+4. Confirming with one or more bottles selected uses those bottles, merged in
+   selection order, as the effective bottle for the session.
+5. Confirming with an empty selection falls back to the agent's `bottle:` field.
+   If neither is set, a ManifestError is raised pointing the operator at the fix.
+6. The ordered bottle list is stored in launch metadata so `./cli.py resume`
+   uses the same bottles.
+7. The preflight summary (`y/N` screen) shows the effective bottle name(s).
+8. The multi-select picker supports incremental filtering, Space/Enter to toggle
+   selection, an ordered "Selected: ..." summary line, Ctrl-D to confirm, and
+   Esc/q to cancel the whole start operation.
+9. Unit tests cover: multi-select widget (filter, toggle, confirm, cancel),
+   the `cmd_start` bottle-picker step, and the manifest `load_for_agent`
+   runtime-bottle-merge path.
+
+## Non-goals
+
+- Reordering the selection list from within the picker (order = insertion order;
+  drag-and-drop is out of scope).
+- Storing bottle selection history / MRU.
+- Changes to `./cli.py edit`, `./cli.py list`, or `./cli.py info`.
+- Removing the `bottle:` key from the agent schema (it stays, now optional).
+
+## Design
+
+### `bot_bottle/cli/tui.py` — `filter_multiselect`
+
+```python
+def filter_multiselect(
+    items: list[str],
+    *,
+    title: str = "",
+    initial: list[str] | None = None,
+    tty_path: str = "/dev/tty",
+) -> list[str] | None:
+    """Multi-select variant of filter_select.
+
+    Returns the ordered list of selected items, or None on cancel.
+    Press Space/Enter to toggle the item under the cursor.
+    Press Ctrl-D to confirm. Press Esc/q to cancel.
+    """
+```
+
+Layout:
+
+```
+Select bottles
+Filter: _
+─────────────────────────────────────────
+> [*] claude
+  [ ] dev
+  [ ] codex
+─────────────────────────────────────────
+Selected (in order): claude
+─────────────────────────────────────────
+[↑↓/jk] move  [Space] toggle  [Ctrl-D] done  [Esc] cancel
+```
+
+`initial` pre-populates the ordered selection. `None` means no pre-selection.
+Items added are appended in insertion order; items removed leave the remaining
+order unchanged.
+
+### `bot_bottle/manifest_schema.py` — optional `bottle:`
+
+`bottle` moves from `AGENT_KEYS_REQUIRED` to `AGENT_KEYS_OPTIONAL`.
+
+### `bot_bottle/manifest_agent.py` — optional `bottle:`
+
+`ManifestAgent.bottle` changes from `str` (required) to `str = ""`.
+`from_dict` no longer requires the key to be present; the bottle-exists
+validation is skipped when the key is absent.
+
+### `bot_bottle/manifest_loader.py` — `scan_bottle_names`
+
+```python
+def scan_bottle_names(bottles_dir: Path) -> list[str]:
+    """Scan <bottles_dir>/*.md and return sorted bottle names."""
+```
+
+### `bot_bottle/manifest.py` — `ManifestIndex` changes
+
+**`all_bottle_names` property** — analogous to `all_agent_names`; scans
+`home_md / "bottles"` in lazy mode, returns `sorted(self.bottles.keys())` in
+eager mode.
+
+**`load_for_agent(agent_name, bottle_names: tuple[str, ...] = ())`** — new
+`bottle_names` parameter. When non-empty, the listed bottles are resolved and
+merged in order (index 0 is the base; each subsequent bottle is applied on top
+using the same field-merge rules as `extends:`). The result replaces the bottle
+that `agent.bottle` would have provided. When empty, falls back to `agent.bottle`.
+Raises ManifestError if neither `bottle_names` nor `agent.bottle` is set.
+
+### `bot_bottle/manifest_extends.py` — `merge_bottles_runtime`
+
+```python
+def merge_bottles_runtime(bottles: list[ManifestBottle]) -> ManifestBottle:
+    """Merge an ordered list of pre-resolved ManifestBottle objects.
+
+    Index 0 is the base; each subsequent entry overrides the previous using
+    the same rules as the file-based extends machinery:
+      - env: dict merge, later wins
+      - git_user: per-field overlay, later wins on non-empty
+      - git (repos): union by name, later wins per-name
+      - egress.routes: concatenate
+      - agent_provider, supervise: later bottle's value replaces earlier
+    """
+```
+
+This function operates on already-parsed `ManifestBottle` objects, so it does
+not need to touch the raw-dict path.
+
+### `bot_bottle/backend/__init__.py` — `BottleSpec` + `_validate`
+
+`BottleSpec` gains `bottle_names: tuple[str, ...] = ()`.
+
+`BottleBackend._validate` passes `spec.bottle_names` to `load_for_agent`:
+
+```python
+manifest = spec.manifest.load_for_agent(spec.agent_name, spec.bottle_names)
+```
+
+The preflight print updates `info(f"bottle: {agent.bottle}")` to display the
+effective bottle name(s). When `spec.bottle_names` is non-empty those are
+shown; when empty and `agent.bottle` is set, the agent's `bottle:` is shown.
+
+### `bot_bottle/bottle_state.py` — persist bottle names
+
+`BottleMetadata` gains `bottle_names: tuple[str, ...] = ()`. `read_metadata`
+reads this from JSON (default `()`). `write_launch_metadata` passes
+`spec.bottle_names` through.
+
+### `bot_bottle/cli/start.py` — bottle multiselect step
+
+After agent selection, before the name/color modal:
+
+```python
+available_bottle_names = manifest.all_bottle_names
+# Peek at agent's bottle default for pre-population
+initial_bottle = _peek_agent_bottle(manifest, agent_name)
+initial = [initial_bottle] if initial_bottle else []
+
+bottle_names_list = tui.filter_multiselect(
+    available_bottle_names,
+    title="Select bottles",
+    initial=initial,
+)
+if bottle_names_list is None:
+    return 0  # user cancelled
+bottle_names = tuple(bottle_names_list)
+```
+
+`_peek_agent_bottle` reads the agent file's frontmatter without full parsing,
+returning the `bottle:` value or `""` when absent.
+
+`BottleSpec` is built with `bottle_names=bottle_names`.
+
+### `bot_bottle/cli/resume.py` — bottle names from metadata
+
+```python
+spec = BottleSpec(
+    ...
+    bottle_names=tuple(metadata.bottle_names),
+)
+```
+
+## Implementation chunks
+

+# PRD prd-new: Egress control plane — metering, budgets, and forced cutoff
+
+- **Status:** Draft
+- **Author:** didericis
+- **Created:** 2026-06-25
+- **Issue:** #251
+
+## Summary
+
+Add an **out-of-band egress enforcement & observability plane**: meter every
+agent's token usage at the egress proxy, decrement budgets without the agent's
+cooperation, and forcibly cut a bottle's egress when a budget is exhausted —
+either automatically or on command from a host-level dashboard. The trigger
+(usage threshold) and the action (route-drop / freeze / kill) both live in the
+egress plane and run with no agent in the loop. This is distinct from the
+supervise sidecar (PRD 0013), which is agent-initiated and therefore cannot
+enforce a cost cutoff on a runaway agent. State (usage ledger, budgets, audit)
+moves into a host-level SQLite database behind a thin repository API, the first
+SQL store in an otherwise flat-file repo.
+
+## Problem
+
+bot-bottle can't currently do two things the cost-overrun case demands:
+
+1. **Forced egress shutdown on limit.** When an agent crosses a token
+   threshold, kill its egress automatically — no human in the loop.
+2. **Remote (host-level) management.** Drive agents from a single surface:
+   see usage, cut egress, stop bottles, to prevent cost overruns.
+
+The existing supervise sidecar (PRD 0013) is **entirely agent-initiated**: every
+action begins with the agent voluntarily calling an MCP tool and an operator
+approving it. A runaway or expensive agent — exactly the cost-overrun case —
+will never call `egress-block` on itself. Supervision is therefore a
+**collaborative recovery** mechanism, not an **enforcement** mechanism; making
+it mandatory (#249) would not deliver forced cost-cutoff.
+
+The requirement forces a distinction the current design blurs:
+
+- **Plane A — enforcement / observability (this PRD).** System → infrastructure.
+  Meter usage, cut egress on threshold or command, account for cost.
+  Out-of-band; independent of the agent. **Unconditional** — an enforcement
+  plane you can opt out of isn't enforcement.
+- **Plane B — agent-facing recovery (the existing supervise sidecar).**
+  Agent → operator, approval-gated. Useful interactively; meaningless for a
+  headless agent with no operator watching its queue. Remains optional.
+
+This PRD builds Plane A. It reframes the "always-on control" invariant of #249
+as "the egress control plane is always present" — a more defensible property
+than "every agent runs the agent-facing supervisor." Unsupervised
+(headless/CI/ephemeral) agents stay first-class: still subject to the mandatory
+meter + kill switch, they simply lack the agent-facing proposal tools they
+couldn't use anyway.
+
+## Goals / Success Criteria
+
+- The egress proxy meters every request to a metered API host (e.g.
+  `api.anthropic.com`) and records authoritative token usage per bottle and per
+  agent provider, with no agent cooperation.
+- A budget can be set at four scopes with deterministic precedence
+  (**agent → bottle → parent bottle → global host budget**); the
+  most-specific applicable budget governs.
+- When usage crosses a budget, the bottle's configured **cutoff policy**
+  (`cutoff` | `freeze` | `kill`) fires automatically, executed host-side on the
+  egress plane — never via the supervise queue.
+- An operator can, from a single **host-level TUI dashboard**, see live per-bottle
+  usage against budget and command a cutoff/stop on demand.
+- Host budgets, default cutoff policy, and per-provider limits are declared in a
+  new host-level `~/.bot-bottle/settings.yml`, parseable by `yaml_subset.py`.
+- All usage, budget state, and enforcement actions persist in a host-level
+  SQLite DB behind a thin repository API, so the store can later be swapped for
+  a cross-host cloud service.
+
+## Non-goals
+
+- **Remote control / cross-host control plane.** Web + mobile remote control,
+  cross-host budgets, and the authn/transport they require are explicitly
+  deferred. v1 is a **host-only TUI** with no remote surface.
+- **Dollar-denominated budgets.** Budgets are token counts keyed by agent
+  provider, not currency. Price tables are out of scope.
+- **Migrating existing flat-file state into SQLite.** Resume `metadata.json`,
+  transcripts, Dockerfile overrides, the supervise queue, and audit logs stay on
+  the filesystem. Only the *new* metering/budget/enforcement ledger is SQL.
+- **Making the supervise sidecar (Plane B) mandatory.** Out of scope here; this
+  PRD is the answer to "what should be unconditional" (Plane A), leaving #249's
+  Plane-B question open.
+- **Per-request hard pre-send blocking as the primary mechanism.** The gate is
+  budget-crossing detected at/after metering; a pre-flight estimator (below) is a
+  refinement, not the core enforcement path.
+
+## Design
+
+### Two measurements: gate vs. account
+
+There are two distinct needs, and they want different signals:
+
+- **Account (authoritative).** Decrement the real budget from the API
+  **response**, which already carries authoritative usage (Anthropic
+  `input_tokens` / `output_tokens`, OpenAI `usage`). The egress addon already
+  has a `response(flow)` hook (`bot_bottle/egress_addon.py:460`), so the real
+  number is available with no extra network call. **Caveat:** agent traffic is
+  mostly streaming SSE, so the response path must tail the stream for the final
+  usage event rather than parse a single JSON body — scoped explicitly as work.
+- **Gate (estimate).** To block *before* sending, only the request is available,
+  so an estimator / provider `count_tokens` endpoint is the only option.
+
+Calling `count_tokens` for accounting would be both less accurate *and* an extra
+metered egress call per request, so accounting uses response `usage` and the
+estimator is reserved for the optional pre-flight gate.
+
+### `count_tokens` on agent providers
+
+Add an abstract `count_tokens(request) -> int` to the `AgentProvider`
+abstraction (`bot_bottle/agent_provider.py`):
+
+- **Default** is a good-enough stdlib estimator. Prefer stdlib only; a small
+  pip dependency *for the sidecar* is acceptable for the fallback if stdlib
+  proves too inaccurate (this does not relax the package's stdlib-first stance —
+  it would be a sidecar-only dep, like the bundle already carries).
+- **Built-in `claude`** uses Anthropic's token-counting endpoint;
+  **built-in `codex`** uses OpenAI's. These are exact for the gate but cost a
+  metered call, so they are gate-only; accounting still comes from the response.
+
+### Budgets and precedence
+
+Budgets are token counts keyed by **agent provider name** (the same names
+bottles already use). Four scopes, most-specific wins:
+
+```
+agent  →  bottle  →  parent bottle  →  global (host)
+```
+
+The global host budget is the highest-priority feature to ship (the cross-host
+control plane will eventually consume it); per-agent and per-bottle budgets
+override it for finer control. A budget can also be supplied **at bottle
+launch** (`--budget` or equivalent), overriding the settings.yml defaults for
+that run. Enforcement evaluates the effective budget as the
+nearest-defined scope at decrement time.
+
+### `~/.bot-bottle/settings.yml`
+
+New **host-level** settings file (the `~/.bot-bottle/` root, *not* the per-repo
+`.bot-bottle/` — host budgets must not be committed per-repo). Parsed by
+`yaml_subset.py`, so it must stay within that bounded subset (flat mappings,
+scalars; no anchors, no multi-line block scalars). Shape:
+
+```yaml
+budget:
+  claude: 5000000      # token budget keyed by agent provider
+  codex: 2000000
+shutdown: cutoff       # default cutoff policy: cutoff | freeze | kill
+```
+
+### Forced cutoff and cutoff policy
+
+On budget exhaustion (or an operator command), the configured per-bottle cutoff
+policy fires. The three policies map onto primitives that already exist:
+
+- **`cutoff`** (default) — drop the bottle's `routes.yaml` to empty and reload
+  (or isolate the bottle from the egress network); the agent/bottle keeps
+  running but can no longer reach metered hosts. This is the route-drop already
+  available on the egress plane (`bot_bottle/backend/egress_apply.py`).
+- **`freeze`** — commit/snapshot state, then kill the agent/bottle; resumable
+  later via `bot_bottle/backend/freeze.py`.
+- **`kill`** — tear the bottle down without saving state (backend teardown).
+
+The trigger lives in the metering path and the action in the egress/backend
+plane; **neither touches the supervise proposal queue** (design constraint from
+#251).
+
+### Host-level SQLite store
+
+**Decision: introduce SQLite now, narrowly.**
+
+- **The dependency objection doesn't apply.** `sqlite3` is in the Python stdlib,
+  so it does not break the AGENTS.md stdlib-first / no-runtime-pip stance — same
+  category as the hand-rolled `yaml_subset.py`, except the stdlib already ships
+  the whole engine.
+- **It fits the problem.** A *global* token budget decremented concurrently by N
+  egress sidecars (today `~/.bot-bottle/` already has `state/`, `audit/`,
+  `queue/` written by parallel bottles) is a read-modify-write race. Over JSON
+  that means hand-rolled file locking; SQLite gives atomic transactions + WAL for
+  free. The per-agent/per-bottle precedence rollup plus "sum across all bottles"
+  is a `GROUP BY`, not an N-directory rescan.
+- **It rehearses the cloud swap.** "Wrap operations in an API so we can swap to a
+  cloud service" maps directly onto a thin repository/DAO over SQLite → Postgres
+  later. A JSON-file store is a worse rehearsal than SQL.
+
+**Costs (real but bounded):** a new paradigm in a flat-file repo needs a
+`schema_version` table + idempotent startup migrations; SQLite serializes
+writers, so WAL mode + `busy_timeout` are required (a non-issue at a handful of
+bottles); test fixtures need temp DBs.
+
+**Scope of the store:** one DB at `~/.bot-bottle/bot-bottle.db` behind a thin
+repository API. Only the **new** metering/budget/enforcement-audit ledger lives
+there. Existing per-bottle blobs (resume `metadata.json`, transcripts,
+Dockerfile overrides, supervise queue) stay on the filesystem — migrating them
+now is churn for no benefit and they lack the concurrency/aggregation problem.
+
+### Host-level controller + dashboard
+
+A single **host-level controller** owns the meter, budget evaluation, and the
+cutoff actions across all bottles (cf. `bot_bottle/cli/supervise.py`'s
+cross-bottle view), rather than a per-bottle daemon. v1 ships one host-level
+**TUI dashboard** that reads live usage-vs-budget from the SQLite store and
+offers on-demand cutoff/stop. The existing supervisor UI should eventually fold
+into this same dashboard; this PRD lays the host-level surface it will move to.
+
+## Implementation chunks
+
+Ordered, individually mergeable:
+
+1. **SQLite repository foundation.** `~/.bot-bottle/bot-bottle.db`, schema +
+   `schema_version` migrations, WAL + `busy_timeout`, thin repository API,
+   temp-DB test fixtures. No behavior wired yet.
+2. **Metering at the egress proxy.** Parse authoritative response `usage`
+   (including SSE final-usage tailing) in the egress addon `response` hook;
+   write per-bottle / per-provider usage rows to the ledger.
+3. **`settings.yml` + budget model.** Host-level `~/.bot-bottle/settings.yml`
+   parsed by `yaml_subset.py`; budget precedence (agent → bottle → parent →
+   global) and the `--budget` launch flag.
+4. **Forced cutoff + cutoff policy.** Wire the threshold trigger to the
+   `cutoff` / `freeze` / `kill` primitives on the egress/backend plane; record
+   enforcement actions to the audit ledger.
+5. **Host-level TUI dashboard.** Live usage-vs-budget view + on-demand
+   cutoff/stop, reading the store.
+6. **`count_tokens` pre-flight gate (optional refinement).** Abstract method +
+   stdlib estimator default; Anthropic/OpenAI endpoints for built-in
+   claude/codex; optional pre-send block.
+
+## Open questions
+
+- **SSE usage tailing robustness.** Buffering streamed responses to extract the
+  final usage event without breaking the agent's own stream consumption — how
+  much of the body must the addon hold, and what's the failure mode if the
+  stream is interrupted mid-flight?
+- **Crossing mid-request.** A single response can push usage past budget only
+  *after* it's already been delivered. Is post-hoc cutoff (next request blocked)
+  sufficient, or is a pre-flight estimator gate (chunk 6) required for v1?
+- **Provider name ↔ metered host mapping.** How does the proxy attribute a
+  flow to an agent-provider budget key — by destination host, by bottle
+  identity, or both?
+- **Parent-bottle budget semantics.** For `bottle extends` (PRD 0025 / 0065)
+  chains, does "parent bottle" mean the manifest parent, the launching bottle,
+  or the full ancestry summed?
+- **Dashboard ↔ controller transport (even host-only).** In-process, a local
+  socket, or polling the SQLite store directly? Picks the seam the future remote
+  control plane will extend.

+"""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)."""
