EgressPlan gains a `canary: str` field (default "") populated in Egress.prepare()
using secrets.token_urlsafe(32). Each launched bottle:
- sidecar receives EGRESS_TOKEN_CANARY=<value> (literal env entry, scanned by
existing known-secrets detector without any detector code changes)
- agent receives BOT_BOTTLE_CANARY=<value> (visible fake secret that signals
exfiltration with zero false positives if it appears in outbound traffic)
Docker compose and macos-container backends updated; smolmachines shares docker
compose and so picks this up automatically. Unit tests cover canary uniqueness,
detection via scan_known_secrets, and EgressPlan backward-compat default.

- _alnum_projection(): strip non-alphanumeric chars for separator-injection detection
- scan_known_secrets() gains two extra passes per secret after exact-variant matching:
alnum-projection exact match (catches hyphens/spaces between secret chars) and a
sliding-window partial-match scan (catches chunked substrings ≥ PARTIAL_MATCH_MIN_LEN)
- scan_known_secrets() accepts sensitive_prefixes param (default ("EGRESS_TOKEN_",))
so redact_tokens and call-sites can extend the scanned env-var prefix set
- scan_entropy() warn-only detector flagging windows with Shannon entropy ≥ 5.5 bits/char
- "entropy" added to OUTBOUND_DETECTOR_NAMES; scan_outbound opts it in only when
explicitly listed in dlp.outbound_detectors (never part of the default "all" set)
- scan_outbound reads BOT_BOTTLE_SENSITIVE_PREFIXES from environ to extend
scan_known_secrets beyond EGRESS_TOKEN_* without schema changes
- Binary bodies decoded via latin-1 fallback (bijective byte↔codepoint) instead
of utf-8 errors=replace, preserving ASCII secret strings in binary payloads

Gitea returns HTTP 422 when a deploy key title or public key content
already exists on the repo. The provisioner previously surfaced this
as a generic RuntimeError with the raw status code. Introduce
DeployKeyCollisionError (a RuntimeError subclass) in the base module
and detect 422 in GiteaDeployKeyProvisioner.create so callers can
catch collisions explicitly and the error message names the repo and
title involved.
The constant and its MCP tool name ("allow" → "egress-allow") were the
only supervise tools without an egress-scoped identifier, despite the
tool being egress-only (routes.yaml payload, COMPONENT_FOR_TOOL maps
it to "egress", always grouped with TOOL_EGRESS_BLOCK). The rename
brings it in line with TOOL_EGRESS_BLOCK and TOOL_EGRESS_TOKEN_ALLOW,
and adds TOOL_EGRESS_ALLOW and TOOL_EGRESS_BLOCK to __all__ (both were
previously absent).
Provider routes (the agent talking to its own LLM API — api.anthropic.com,
the Codex backend, etc.) carry the whole conversation payload, which is the
worst source of token-shaped false positives. egress_routes_for_bottle now
fills outbound_on_match=redact on any provider route that doesn't set it
explicitly, so a match there is scrubbed and forwarded rather than blocked
or queued for the operator. A provider that sets the policy keeps its
choice; manifest routes still default to supervise.
Tests: provider route gets redact default, explicit provider policy
preserved, manifest route unaffected. README + PRD 0062 updated.

A 403 "egress DLP: URL-encoded CRLF (%0d%0a)" was firing on legitimate
requests (e.g. the Claude Code login flow) and bypassing the on-match
policy entirely, because CRLF blocks carry no matched value and were
routed straight to a hard 403.
Root cause: CRLF injection is only an attack in the request line and
headers. An HTTP body is delimited by Content-Length, so CRLF bytes in
the body cannot split the request — but the scan flattened the body into
the same blob it checked, so form-encoded / multi-line body content
(which legitimately contains %0d%0a) tripped it.
Fix:
- scan_outbound takes a crlf_text param; the addon scans CRLF only over
the body-excluded request line + headers. crlf_text=None keeps the
old full-blob behavior for host-side callers/tests; the websocket path
passes "" since a data frame is not a request line.
- The redact policy now also scrubs CRLF (new strip_crlf helper) from the
path and headers, so redact is a complete escape hatch and structural
CRLF in the URL/headers can be forwarded when a route opts into it.
Tests: strip_crlf unit tests; scan_outbound crlf_text body-exclusion and
backward-compat tests.

Give each egress route a policy for what the proxy does when an outbound
DLP detector matches a token, defaulting to the supervise flow added in
the previous commit. The goal is cutting false-positive friction without
weakening default-deny.
- redact: scrub the matched value(s) from the body, non-host headers, and
path/query via redact_tokens, then re-scan. Forward if clean; fail
closed with a 403 if a match remains on a surface redaction can't
rewrite (the hostname, or a unicode-evasion token). For routes where a
token-shaped value is noise the upstream doesn't need.
- block: the original hard 403, never overridable.
- supervise (default, unset): hold the request for operator approval.
Structural blocks (CRLF, no safelist-able value) stay hard 403s under
every policy.
Threads outbound_on_match from the bottle manifest (manifest_egress)
through the resolved EgressRoute and rendered routes.yaml (egress.py) to
the addon's Route (egress_addon_core), and round-trips it via the
list-egress-routes introspection endpoint. The allow/egress-block tool
descriptions document the new key.
Tests: manifest parse/validation, core parse/validation, full
manifest->render->addon round-trip for redact. README + PRD 0062 updated.

When the outbound DLP catches a token, route the block through the
existing supervisor approval queue instead of returning 403 outright.
The egress proxy holds the request open until the operator answers, then
remembers an approved value for the life of the proxy so the request --
and later ones carrying it -- flow through. Fails closed on rejection,
timeout, malformed response, or when supervise is disabled.
- ScanResult.matched carries the raw matched substring (sidecar-only;
never logged or written to the proposal). scan_outbound and the token
detectors take a safe_tokens set and skip approved values, continuing
past a safelisted match so a second secret in the same request is
still caught.
- New egress-token-allow proposal tool, written directly to the queue by
the addon (the gitleaks-allow pattern from PRD 0061). build_token_allow
_payload renders host/method/path/detector reason + redacted context.
- Async request hook polls the queue without stalling the proxy event
loop; EGRESS_TOKEN_ALLOW_TIMEOUT_SECONDS (default 300) bounds the wait.
- Supervisor TUI renders egress-token-allow like gitleaks-allow: report
only, modify unavailable, approval requires a recorded reason.
- Unit tests for the matched/safe-tokens plumbing, payload builder, tool
constant round-trip, and TUI paths; README + PRD 0062.
Closes#261.

log.py was bare print-to-stderr wrappers with no levels or attributable
context (issue #252). Add:
- Ordered severities (debug/info/warn/error) gated by
BOT_BOTTLE_LOG_LEVEL (default info). debug is silent by default;
error always surfaces (nothing sits above it), so the fatal die path
stays visible regardless of configured level.
- An optional `context` mapping on every wrapper, rendered as a
parseable ` [k=v ...]` suffix (keys sorted; whitespace/quoted values
quoted) so failures can be filtered and correlated.
Default output with no context is byte-identical to the original lines,
so the 100+ existing single-string call sites are unaffected. Wires the
supervise crash path (the example the issue names) to attach error_type
and crash_log context. Adds test_log.py (backward-compat, context
rendering, level gating, die surfacing).
Closes#252.

The TUI was calling archive_proposal for gitleaks-allow immediately
after write_response, moving the response file to processed/ within
microseconds. The git-gate shell loop polls queue_dir for the response
file every second — it never sees it and hangs until timeout.
capability-block is handled by the MCP sidecar which archives after
reading; gitleaks-allow is handled by the shell gate which archives
after processing. Let the gate own the archive step.
smolvm pack create --from-vm requires the VM to be stopped, and stopping
a smolmachines VM terminates any running interactive session.
Instead, mirror the macos-container approach: exec into the running VM as
root and stream the root filesystem via tar (smolvm machine exec -- tar),
build a Docker image from the archive, push to an ephemeral local registry,
and run smolvm pack create --image to produce the .smolmachine artifact.
The VM stays running throughout the commit.
Remove the stop-confirm prompt and machine_is_running check that were
added in the previous commit — neither is needed when we no longer stop.
smolvm pack create --from-vm requires the VM to be stopped. Add
machine_is_running() to smolvm.py (via machine ls --json state field),
and add the same confirm-stop flow to SmolmachinesFreezer that was
originally designed for macos-container: if running, prompt the user,
stop the VM, then pack. Already-stopped VMs are packed directly.
- Rename export test to reflect new exec-tar mechanism; update argv
assertions to match the new `container exec ... tar` command shape
- Change mock stderr from str to bytes (subprocess.PIPE without text=True)
- Add type annotation to capture_freeze closure to satisfy pyright
Apple Container removes containers when they stop, making the
stop-then-export flow impossible regardless of the --rm flag.
Replace `container export` (requires stopped container) with
`container exec --user root <name> tar --create ... --file=- --directory=/ .`
streamed to a temp file, then build the committed image from that archive
as before. The bottle stays running after commit, which is better UX.
Drop the stop-confirm prompt from MacosContainerFreezer since we no longer
need to stop the container at all.
Freezer._freeze only ever used bottle.name, which is always
f"bot-bottle-{agent.slug}". Remove the Bottle parameter from
commit() and _freeze(), derive the container name from agent.slug
directly in each subclass, and delete the _NamedBottle stub that
existed solely to paper over this.
Adds a Freezer ABC (backend/freeze.py) that encapsulates the
stop-commit-mark-preserved flow for all backends, following the same
pattern as BottleBackend. Each backend gets its own Freezer subclass:
DockerFreezer — docker commit
MacosContainerFreezer — container export + image rebuild; prompts
to stop if the container is running
SmolmachinesFreezer — smolvm pack create --from-vm
The base class owns write_committed_image, mark_preserved, and the
resume hint. Subclasses implement _freeze() and optionally override
_export_hint() for migration instructions.
Freezer.commit(agent, bottle) is the primary entry point for use
within a live launch context. Freezer.commit_slug(slug) is a
convenience wrapper for cmd_commit, which no longer branches on
backend names itself.
get_freezer(backend_name) is the factory, analogous to
get_bottle_backend(). CommitCancelled is raised by MacosContainerFreezer
when the user declines the stop prompt; cmd_commit catches it and
returns 0.
`container export` requires the container to be stopped first. When a
running bottle is detected, prompt the user to confirm, stop the
container, then commit. Adds `container_is_running` and
`stop_container` helpers to the macos-container util.
Addresses #240 (comment)
- test_docker_launch_committed_image: replace Manifest.from_json_obj
(nonexistent) with ManifestIndex.from_json_obj; pass manifest= arg
to DockerBottlePlan constructor (required by BottlePlan base class)
- test_macos_container_launch: cast SimpleNamespace stubs to their
expected types (BottleSpec, GitGatePlan, EgressPlan) in _build_plan;
add str type annotations to fake_build parameter signatures
- test_macos_container_util: add str type annotations to fake_build_image
parameter signatures
Adds `./cli.py commit [<slug>]` which runs `docker commit` on the
active agent container and stores the resulting image tag in per-bottle
state. The next `./cli.py resume <slug>` automatically boots from the
committed snapshot instead of rebuilding from the Dockerfile, preserving
all in-container state across restarts and migrations.
- bottle_state: add write_committed_image / read_committed_image helpers
- docker/util: add commit_container wrapper around `docker commit`
- docker/launch: check for a committed image before the Dockerfile build
step; fall back to normal build if the image is absent from the daemon
- cli/commit: new command with interactive slug picker; errors clearly on
non-Docker backends
- 50 new unit tests covering all paths

Replace module-level apply_routes_change wrappers with a public
applicator singleton in each backend. Callers now work with the
EgressApplicator instance directly (applicator.apply_routes_change)
rather than through a function shim.
Mirrors the fix already applied to the macos-container backend in
eb3e64e: bind-mount the parent egress directory instead of the
routes file itself, so the live routes update is visible inside the
running sidecar bundle when the host overwrites the file.
BottleSpec.manifest was ManifestIndex | Manifest — a union encoding
two lifecycle stages in one field. The union was unjustifiable:
it forced a type-narrowing workaround (loaded_manifest property)
on every consumer.
Clean split:
- BottleSpec.manifest: ManifestIndex (always; CLI-supplied intent)
- BottlePlan.manifest: Manifest (always; loaded by _validate())
_validate() returns the loaded Manifest directly. prepare() passes
it to _resolve_plan(), which stores it on the plan. All provisioner
code now reads plan.manifest.agent / plan.manifest.bottle — no
union, no asserts, no type: ignore.
BottleSpec.manifest is ManifestIndex | Manifest (pre/post _validate()).
Downstream code always runs post-validate so it needs Manifest, but
pyright flagged every .agent/.bottle access. The new loaded_manifest
property asserts isinstance and returns Manifest, giving pyright a
narrowed type without scattering type: ignore everywhere.
Also remove unused Manifest imports from test files and annotate the
_index() helper in test_manifest_agent_git_user.
Manifest now holds exactly one agent and one effective bottle (with
git_user overlay already applied). The old multi-agent/bottle
collection is renamed ManifestIndex. BottleSpec.manifest starts as
ManifestIndex from the CLI and becomes Manifest after _validate()
calls load_for_agent(); all provisioning code downstream reads
spec.manifest.agent / spec.manifest.bottle instead of indexing by name.
Manifest.resolve() now returns an empty-dict manifest with only directory
paths recorded (home_md, cwd_md). No content is read from any .md file
until load_for_agent() is called for a specific agent at preflight.
- Manifest.from_md_dirs: scan-only, no frontmatter parsing
- Manifest.load_for_agent: parses the selected agent file and its bottle
chain; works on eager (from_json_obj) manifests too by returning self
- Manifest.all_agent_names: scans filenames in lazy mode
- backend._validate: calls load_for_agent and propagates upgraded spec
- cli/info.py, cli/list.py, cli/start.py: use load_for_agent / all_agent_names
- manifest_extends.py: reverted to original (no partial-resolve helpers)
- manifest_loader.py: only scan_agent_names + load_bottle_chain_from_dir
- Tests updated to call load_for_agent before accessing agents/bottles;
test_md_agent_repos_deferred renamed to test_md_agent_repos_fails_at_preflight
Broken bottle/agent files no longer block the agent selector or prevent
unrelated agents from loading. Per-file parse errors are collected in
`Manifest.broken_agents`; the CLI selector includes them via
`all_agent_names`, and the error surfaces only when the specific agent
is selected and launch is attempted (in `require_agent`/`bottle_for`).
Closes#236
Apple's container exec --interactive --tty does not put the host
terminal into raw mode before starting its I/O relay. In cooked
(canonical) mode the kernel line discipline buffers modifier-key
escape sequences — e.g. Shift+Enter in modifyOtherKeys mode generates
\x1b[13;2~ — until a carriage-return arrives, so they never reach
Claude Code inside the container.
Add pty_forward.py, a stdlib-only wrapper (modelled on the existing
smolmachines pty_resize.py) that sets the host terminal to raw mode
via tty.setraw(), spawns the container exec command, and restores the
original terminal attributes on exit. Falls back to a bare
subprocess.run when stdin is not a TTY (piped invocations, CI) or
when termios operations fail.
Also retain the --env TERM=<host> forwarding from the previous commit:
without TERM inside the container session, Claude Code cannot determine
which modifier-key protocol to enable even with raw mode correctly set.
Non-TTY exec paths (bottle.exec, cp_in) are unaffected.
Without TERM, Claude Code inside the container cannot determine which
modifier-key protocol to enable (modifyOtherKeys / kitty). The inner
PTY session has no terminal-type context, so Shift+Enter and Enter
produce identical byte sequences (\r), making them indistinguishable.
Pass the host TERM via --env TERM=<value> on every container exec
--interactive --tty call, falling back to xterm-256color when TERM
is not set on the host. Non-TTY exec paths are unaffected.
Closes#245
When a label is given it is now used verbatim as the slug (no random
suffix), so two launches with the same label collide by design. The
CLI re-prompts via the TUI name modal with a disclaimer when the
candidate slug is already in use among running bottles.
When a user names a bottle via the TUI label field, that name is now
used as the slug prefix for the container identity instead of always
falling back to the agent name.
Remove the 8 non-bright and 1 bright-black colors from all color maps.
Rename the remaining 7 bright-* colors to their base names (e.g.
bright-green → green) so the palette is smaller and always vibrant.
Update _init_color_pairs in tui.py to always apply A_BOLD (all palette
entries are now bright variants), and fix all tests to match.
