BaseChannel.is_allowed ORs is_approved (the pairing store) into the
allow decision; the signal override dropped that step and only looked
at config.allow_from. With the new DM-pairing flow in place, an
approved-via-pairing sender's next message would have failed the
allow check and triggered another pairing code in a loop.
OR in a normalized check against the pairing store: walk each part of
the pipe-joined sender_id through _normalize_signal_id and call
is_approved for each variant, so an approval stored under one form
(phone with/without "+", UUID/ACI) still matches when the next inbound
uses a different form. Mirrors how slack.py:643 handles it.
Also tightens the empty-allowlist warning to only fire when nothing
else granted access, since pairing-store hits are now a valid path.
Not part of the original review, but Comments 2 and 3 turn this latent
gap into a broken round-trip — included so the pairing UX actually
works.
Per the SSE spec, multiple data: lines within a single event must be
joined with \n before parsing. signal-cli emits single-line JSON so
this was latent, but the joining was wrong.
Addresses review comment on PR #3852.
Previously _check_inbound_policy returned (False, chat_id) for DMs
that failed the allowlist and the caller dropped them — so unapproved
DM senders never saw a pairing code. Mirror Slack: when the policy
gate denies a DM but dm.enabled is true, still call
_handle_message(content="", is_dm=True) so BaseChannel can issue the
pairing reply. Group denials stay a hard drop.
Combined with the previous is_dm forwarding, unapproved DM senders
now receive a pairing code through the standard flow.
Addresses review comment on PR #3852.
BaseChannel._handle_message uses is_dm to decide whether to issue a
pairing code when is_allowed rejects the sender. Without it the base
class treats every denied message as a group message and silently
drops it. Forward is_dm=not is_group_message so unapproved DM users
get a pairing code through the standard flow.
This change only takes effect once denied DMs actually reach
_handle_message (next commit); on its own it is a no-op since the
policy gate still short-circuits before this call.
Addresses review comment on PR #3852.
_send_http_request collapses every exception path into a {"error": ...}
dict, so the if "error" in response branch inside send() is the only
place where send failures surface. Logging-only there meant the
ChannelManager retry mechanism never fired. Raise RuntimeError so the
base-class retry path is exercised; the outer try/except already
re-raises into the caller.
Addresses review comment on PR #3852.
The base BaseChannel.is_allowed() does a literal ``sender_id in allow_from``
check, but Signal's sender_id is a pipe-joined composite of phone/UUID
parts. After splitting an allowlist entry like ``+phone|uuid`` into two
separate entries, the per-DM gate accepted it but the base gate still
denied because the composite sender string wasn't literally in the list.
Override is_allowed on SignalChannel to delegate to
_sender_matches_allowlist, which already splits both sides on ``|`` and
normalizes each part. _sender_matches_allowlist itself now also splits
allowlist entries on ``|`` so legacy composite entries keep working too.

The existing markdown suite was strong on UTF-16 offsets and chunk
redistribution but had no coverage for nested or adjacent styles, no test
that an unmatched opener round-trips as plain text, and no test for the
blockquote/inline-code interaction. Add six cases including the
documented contiguous-BOLD output for `# **wrap** me`, which Signal
renders as one visual span.

Two test classes (TestHandleDataMessageDM, TestHandleDataMessageGroup)
plus three TestCommandHandling tests each repeated the same handful of
lines: build a channel, mock _handle_message to record kwargs, replace
_start_typing with a no-op, paper over the assignment with type: ignore.
Hoist the pattern into _make_channel_with_capture and call it from all
five sites. Drops 30+ lines of duplication and 7 type: ignore comments.

Previously the SSE loop and the empty-phone-number short-circuit in start()
had zero coverage. Both now have tests: a fake httpx stream feeds canned
SSE lines, exercising the valid-frame, invalid-JSON, non-200, and
no-http-client paths; start() with an empty phone number is asserted to
return without entering the HTTP loop.

The receive-path handler was ~165 lines deep into nested DM/group policy
checks, buffer mutations, mention stripping, attachment downloads, and
final bus forwarding. Pull the policy gate out into _check_inbound_policy
(returns (allow, chat_id), still appends to the group buffer once allowed)
and the text+media construction into _assemble_inbound_content. The
top-level method now reads as orchestration only.
Add TestCheckInboundPolicy that exercises the helper directly across the
DM/group policy permutations, including the buffer side effect, so the
new seam is locked in.

The inbound attachment loop hardcoded ~/.local/share/signal-cli/attachments
as the source path. That is the daemon's default on Linux but not on macOS
or Windows, and breaks if the daemon was launched with XDG_DATA_HOME set.
Add SignalConfig.attachments_dir as an optional override. When unset the
behavior is unchanged; when set the value is run through Path.expanduser()
so ~ is honored.

Replace the inline try/except at the end of _handle_receive_notification
with a small async context manager that swallows the exception, logs
self.logger.error with the offending payload's repr (bounded to 200 chars),
and attaches the traceback via logger.opt(exception=True).
The previous log line only carried `e`, so diagnosing a bad envelope from
production logs required correlating timestamps. The wrapper is generic so
future receive/dispatch sites can adopt it; for now only this site uses it.

The DM allowlist check split sender_id on '|' and looked for raw membership
in the allow_from list. Senders carry their phone number with a leading
'+' but admins routinely write allowlist entries without it (or vice
versa), and UUID/ACI matches were case-sensitive. Both forms now flow
through _normalize_signal_id, so an entry like 19995550001 matches a
sender +19995550001 and a UUID matches case-insensitively.

- Hoist the cell-strip patterns to module level so they match the rest of
the module's regex style and aren't reparsed on every call.
- Type the markdown transform callback and the mention id walker so the
inline Callable signature is no longer an untyped Any.
- Add _HTTP_TIMEOUT_SECONDS alongside the other class-level tunables.
- Reject group_message_buffer_size <= 0 in a Pydantic field_validator
rather than silently disabling the buffer at write time.
- Mark SignalConfig.allow_from as a computed_field so it shows up in
model_dump() instead of being invisible to serialization.

split_message can break a long Signal payload into multiple JSON-RPC sends,
but the previous code attached the full textStyle list only to chunk 0.
Style ranges in later chunks were dropped, and ranges whose offsets pointed
past chunk 0's end were sent as invalid metadata against chunk 0.
Add _partition_styles, which rebases each range against the chunk it lives
in (in UTF-16 code units, matching the markdown converter) and splits
boundary-spanning ranges across the chunks they touch. Whitespace trimmed
by split_message's lstrip is skipped so offsets stay aligned.

Signal's BodyRange (via signal-cli's textStyle) interprets start/length as
UTF-16 code units, but the Phase-3 assembly used Python's len(), which counts
code points. A single non-BMP character (e.g. an emoji) earlier in a message
shifted every subsequent styled span left by one unit, dropping the last
letter of bold/italic words.
Track a running UTF-16 offset in the assembly loop and add regression tests
covering emojis, supplementary CJK, ZWJ sequences, and a multi-section
message that mirrors the reported failure.

Integrates signal-cli daemon via HTTP JSON-RPC as a nanobot channel.
Supports DMs and group chats with open/allowlist access policies,
markdown→Signal text style conversion, typing indicators, attachment
handling, group message context buffering, and automatic reconnect
with exponential backoff.
Includes unit tests for channel lifecycle, message routing, mention
detection, markdown conversion, and message splitting.

Add APIFree as a built-in OpenAI-compatible provider. APIFree offers
agent-optimised models such as skywork-ai/skyclaw-v1 through an
OpenAI-compatible API at https://api.apifree.ai/agent/v1.
Changes:
- Register apifree provider in the provider registry
- Add config schema field
- Add documentation with configuration example
- Add provider tests, websocket channel tests, and webui tests
- Add provider icon in settings UI
Channel lazy load: discover_enabled() only imports enabled channel
modules instead of all 18 modules with heavy SDKs (telegram, discord,
slack, etc). discover_all() now delegates to discover_enabled().
Lazy OpenAI client: defer AsyncOpenAI() + httpx construction to
_ensure_client() with asyncio.Lock double-checked locking. openai
and httpx imports moved from module-level into _ensure_client().
Minor: lazy Nanobot/RunResult and CronService exports via __getattr__.
Benchmark: 6910ms → 460ms (-93.3%)
- Remove generated_image_paths_from_messages() and _extract_text_payload() from artifacts.py (no runtime callers)
- Remove session_attachments.py entirely (merge_turn_media_into_last_assistant and stage_media_paths_for_session_replay had no runtime callers)
- Remove test_session_media_persist.py and the orphaned test in test_artifacts.py
The runtime media-attachment mechanism was broken for streaming channels
(e.g. WebSocket): the _streamed flag caused _send_once to skip the final
OutboundMessage that carried generated media, so images were never delivered.
Rather than adding complex coordination between streaming and media delivery,
delegate image delivery to the LLM: after generate_image returns artifact
paths, the next_step prompt now instructs the LLM to call the message tool
with the paths in the media parameter. This works uniformly across all
channels, streaming or not.
Remove generated_media from TurnContext, _assemble_outbound, and _state_save.
Update prompts in identity.md, SKILL.md, message tool description, and
artifacts.py to reflect the new flow.
Updates docs/image-generation.md and skills/image-generation/SKILL.md to
include MiniMax configuration examples, supported aspect ratios, and
troubleshooting references. Also updates the supported provider list to
include minimax alongside openrouter, aihubmix, and gemini.
Adds ImageGenerationProvider ABC with shared __init__, _http_post(), and
_require_images(). Introduces _IMAGE_GEN_PROVIDERS registry with
register/get/image_gen_provider_configs() helpers.
Four existing providers (OpenRouter, AIHubMix, Gemini, MiniMax) now inherit
from the base class and self-register. Adding a new provider only requires
writing one class + one registration line.
Eliminates if/else chains in the tool dispatch and hardcoded provider config
dicts in commands.py (3 sites) and nanobot.py (1 site). Fixes the agent CLI
command missing image_generation_provider_configs entirely.
Also simplifies test monkeypatch targets to patch the registry lookup.
Adds GeminiImageGenerationClient covering both Imagen 4 (:predict) and
Gemini Flash (:generateContent), wires the gemini ProviderConfig through
the SDK, API server, and gateway entry points, and updates the
image-generation docs and skill. Errors from the Gemini endpoints are
logged and surface with the HTTP status and parsed message instead of an
empty string.

Add MiniMaxImageGenerationClient with support for:
- Text-to-image generation via MiniMax image-01 model
- Reference image support (subject_reference)
- Aspect ratio selection
- Proper error handling aligned with existing providers
Wire up MiniMax provider config in ImageGenerationTool, gateway,
serve, and Nanobot class.
