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.
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.
_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.

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.

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.

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.
