refactor(composer): share the send column, attach input and paste trim - #1890
Merged

Conversation
Step 2 of the Group Chat composer parity plan. New
src/renderer/components/ChatComposer/ holds three leaf pieces both composers
now render or call, and none of them knows about sessions, tabs or rooms:
- ComposerSendColumn: the notification bell and Send button. The surface
passes the title, disabled state, tint and an optional Send menu read at
click time. NotificationSendControls is now the AI binding over it (Send
menu, terminal-mode title, aria attributes unchanged); Group Chat keeps its
disabled-without-text Send and its warning "Queue message" tint while busy.
- ImageAttachInput / stageImageFiles: the hidden file input and its read,
staging through addStagedImageIfUnique and reporting read errors and aborts
through captureException plus a flash. Buttons click it through a ref
instead of getElementById. An optional checkFile refuses a file before it is
read; only Group Chat passes one (its type allowlist and 10MB cap), so AI
chat behaves as before.
- applyTrimmedTextPaste / clipboardHasImage: the paste-trim logic both
composers carried. The current value is a parameter, so the room still
splices into its message state and persists the draft, and useInputHandlers
still leaves room text pastes to the room.
What a Group Chat user now sees differently: a picked image that is the wrong
type or over 10MB flashes the reason ("Unsupported image type (PNG, JPEG, GIF
or WebP)" / "Image too large (max 10MB)") instead of being dropped with only a
log line, and a failed or aborted read flashes "Failed to attach image" /
"Image attachment canceled" and is reported.

Keep rationale out of the index entry.
The index rule applies here. The surface-specific usage details and the prohibition belong in the canonical entry, not in CLAUDE.md. This line is 319 characters, so it does not exceed the verifier’s 320-character limit; docs:verify does not necessarily fail for this entry.

@reachrazamair thanks for this one, and for keeping the composer parity stack in small, reviewable steps. 🙏 I reviewed the diff and the Greptile and CodeRabbit passes. This PR is good to merge:
One optional nit, not a blocker. You could fold it into #1891 or #1892: CodeRabbit is right that the three new Approved. ✅ |

The CLAUDE.md index is symbols and paths only (review note on #1890). Trims the send column and Attach Image lines #1890 added, and this step's composer keys line. The dropped usage notes (NotificationSendControls and the room's disabled / warning tone, the duplicate and read error reporting, clicking the input through its ref, isolateFromWindowKeys) are already in their full entries in docs/agent-guides/CANONICAL-UTILITIES.md. The send column line was 319 characters, one under the docs:verify cap.

The Progress section and the Step sequence table still said steps 2-5 were on unmerged stacked branches. Step 2 merged into rc as #1890 (9d6f5b2), so its Progress row cites the rc merge commit as step 1's does, and its Step sequence note says merged. Steps 3, 4 and 5 name their PRs (#1891, #1892, #1945), and step 3 now sits off rc rather than on step 2. The step commits in both tables are unchanged: each branch's tip moved on 2026-10-28 only by a CLAUDE.md index trim and the merges that carry it up the stack, which complete no rows. The Progress intro says so.
