fix(web): limit project monograms and retain icon save errors - #22831
Typing ABCD in Settings → Projects → Choose icon → Monogram kept all four characters; Save closed the picker and showed “Failed to mutate project.” The server returned “Project monograms must contain at most two characters.” Reproduced twice on 1688f965 using the real isolated web app.
Change
Normalize input before keeping two complete graphemes, preserve composition until commit, and disable invalid saves. Await icon saves and retain the selection with an inline server reason on failure; Icons and Emoji share that save behavior. Contracts remain unchanged: snapshot decoding permits up to32 code units; the server command enforces two graphemes. Mobile has a separate renderer and no shared picker.
The supplied issue number maps to #22794 on GitCafe by exact title and author; GitHub report #22793. No issue comments, labels, closes or conversions were made.
Verification
Compared merge-base 1688f965 with head 7aa1e55f7b: 13/13 rows captured, 52 matched condition pairs, 96 recordings, plus eight S0 contact sheets containing 24 original source stills.
Full capture index with runner-clock narration and disclosed media offsets, Before/After media and mutation/event traces. The public index is the exact audited snapshot, sha256 d5907f06b542e926e8c03593015710d57ceef3d737af23dd2a13addf3623ad52; the superseded 19:09 upload must not be cited. Each table link below opens its named pair; narration appears above that pair in the index. Runner timestamps are not exact video seek times: measured desktop visible opening is 1.45–2.17s into the media and later sampled actions roughly +1.5–2s from runner offsets; narrow opening is 0.30–0.92s with later action lag generally under 0.9s. Offsets include action latency. Videos are ordinary links.
Narration: M1 holds a valid AB/blue save, attempts a repeat, releases and reopens. M2 types a/b/c/d separately. M3 performs all five real clipboard pastes and saves/reopens the Unicode cases. M4 attempts pointer/Enter saves on empty, spaces and A!, then corrects AB. M5 uses disclosed synthetic composition through commit. M6 rewrites outgoing AB→ABC for the real server invariant rejection, then retries AB. M7 injects generic failures, edits AC, cancels/reopens and saves. I1/E1 hold the selected icon/emoji save through edit and dismissal attempts; I2/E2 inject failure then retry. The raw I2 trace step labels preserve the runner’s original wording, including “duplicate Save attempt”; request modes/counts and the corrected index narration govern that claim. I2 head’s second Save follows unlock after the immediate failure: two sequential rejected requests precede the final successful retry; it does not prove in-flight deduplication. Emoji reopening additionally re-saves the unchanged selection to verify restoration. R1 seeds AB/blue, holds Reset with an explicitly synthetic same-turn handler double invocation, attempts panel actions, then exercises failure/retry. S0 shows all three resting picker tabs.
Independent proof audit: VERDICT: SUFFICIENT, Claude Opus 5.5 through ClaudeAgent. The audit’s exact findings and inspection limits govern this evidence. The first review decoded all 96 and checked traces/timing; directly inspected selected frames from about a dozen recordings and one S0 pair, and watched none continuously end to end. Capture counts do not imply every matrix checkpoint was verified.
Unverified boundaries: native OS IME (M5 is synthetic), native iOS/Android, Electron native file selection, remote/relay/tunnel and multi-environment/member behavior. R1 checks Choose file availability only. The custom emoji entry field reopens blank on both revisions; persistence/restored selection is proven by the settings value and unchanged real re-save, not by a refilled field. I1/I2 picker selected-icon/color restoration on reopen is unverified in all four conditions on both revisions: Layers 2 is off-grid and the helper clicks Blue after reopening. Persistence is proven by Settings and real success responses. M4 aria-invalid was not retained in the trace or independently asserted; head spaces normalize to empty. Pending deduplication evidence comes from M1/I1/E1 and R1, not I2.
Environment: fs-13 fleet VM, Linux 6.1.102 x86_64; Chromium 154.0.0.0 desktop UA; DPR 2; root font 16px/default scaling; system UI fonts with Noto Color Emoji/Unifont fallbacks; UTC. UI clock frozen after auth to 2026-10-21T12:00:00Z, server clock real. Light/dark forced consistently. C4 is responsive web. Encoded videos are 2880×1800 and 780×1688; original preview PNGs are 1280×800 desktop (tool downsampling) and 780×1688 narrow. Source stills are unaltered inside labeled contact sheets.
The dev runner internally set T3CODE_HOME to its worktree .t3; the agent did not set an ambient override. Both servers used isolated state; head ports 14735/6695, before 15415/7375. Fixture folder /tmp/t3-monogram-evidence, retained identical display name t3-monogram-evidence on both revisions, one local environment/member, Automatic icon reset between cases, Layers 2 for icon fixtures. Baseline prior-case toasts persist at frame zero in 1440-light M6/E1 and 390-light/dark M3/M6; first-frame scans also flag likely 390 M4 carry-over. These starts are not pristine independent resets. The index discloses each affected recording; the stale desktop M6 toast is gone by 1.18s and the current-operation toast appears separately at about 5.35s. Synthetic hold/failure/composition/handler probes are disclosed per recording; M6 alone uses an actual server-rule rejection. No agents ran in the fixture. Disk: 3.5 GB initially, approximately 2.86 GB after teardown, never below the 2 GB stop threshold. Original capture and later excluded probe sessions stopped by Ctrl-C through captured exec sessions; no listeners remain on their four ports. Worktrees are clean; PR body/comments/branches unchanged. No forge CLI, repo-wide checks or check-monitor watch mode ran.
Capture: GPT-6.1-Sol, Codex harness. Public writes limited to requested ghdrop evidence uploads.
Evidence re-captured as recordings per EVIDENCE.md (capture: Codex gpt-6.1-sol; proof audit: Claude Opus 5.5).
Implemented with Codex gpt-6.1-sol in T3 Code; independently reviewed with Codex gpt-6.1-sol and Claude Opus 5.5.
Focused save-guard follow-up
93ecde635d moves both save-guard resets into finally, so a throwing error formatter cannot strand the dialog. The button now returns the save promise directly. The formatter itself is unchanged.
Verification: the new executable handler regression injects a rejection with a throwing cause getter, verifies saving is cleared, dismissal works, and a second save succeeds. It fails with the old cleanup placement and passes with this fix. Both focused unit files pass (6 tests); changed-file lint/format and web-only typecheck pass (existing Effect suggestions only). Tests use mocked React hooks, not a mounted client. No browser was authorized for this follow-up; earlier recordings do not certify this diff. Browser/native/remote runtime verification remains a gap.
Follow-up: GPT-6.1-Sol through the Codex harness in T3 Code.

Walkthrough
The project icon picker now normalizes monogram input, validates it before saving, and waits for icon updates to complete. Failed saves leave the dialog open and show an error message. Project settings and the update hook now support forwarding update failures.
Changes: Project icon picker
Layer / File(s)
Summary
Monogram normalization and validation apps/web/src/projectIconOptions.ts, apps/web/src/projectIconOptions.test.ts, apps/web/src/components/settings/ProjectIconPickerDialog.tsx
Monogram input is NFKC-normalized, trimmed, uppercased, and limited to two grapheme clusters. The picker validates normalized input and disables controls while saving.
Project icon updates return an AsyncResult and accept an optional failure callback. The callback is forwarded to updateProjectGroup and used for generated failures.
Asynchronous save and error display apps/web/src/projectIconOptions.ts, apps/web/src/projectIconOptions.test.ts, apps/web/src/components/settings/ProjectIconPickerDialog.tsx, apps/web/src/components/settings/ProjectSettingsPanel.tsx, apps/web/src/components/settings/ProjectIconPickerDialog.browser.test.tsx
The picker awaits the icon update and closes after success. On failure, it stays open and displays a message derived from nested causes. The browser test covers a failed save and successful retry.
Access-denied failures when changing a project icon will show both a toast and an inline error. This is a minor duplicate-notification issue and worth fixing before or soon after merge.

Explanation
Issue #22793 requires client-side enforcement of the existing two-grapheme limit, an open picker after a failed save, and a useful validation message. ProjectIconPickerDialog normalizes input, retains complete graphemes, blocks invalid monogram saves, awaits onSelect, and closes only after success. Rejected saves restore the controls, keep the picker open, and show the nested server reason. Focused unit tests and a browser test cover normalization, error mapping, failure recovery, and retry. The follow-up regression covers cleanup when error formatting throws.
Full details: Out of Scope Changes check
Explanation
The changes remain within issue #22793. ProjectIconPickerDialog, project icon save handling, related failure propagation, and focused tests support the picker requirements. Shared save behavior for Icons and Emoji supports the same failure and retry behavior. No unrelated server contract, mobile renderer, or feature changes are identified in the reviewed summary.

Remove the finally clause to restore the web test run.
The React Compiler coverage test fails at Line 119 because the compiler skips a component containing try with finally. Keep cleanup on both outcomes without finally. In the catch path, clear savingRef and saving before formatting the error, since formatting can throw.
The web UI rules require every file under apps/web/src to compile. The supplied CI failure confirms this violation.

Forward onFailure to the access checks, or the picker reports access failures twice.
updateProjectGroup accepts onFailure. It forwards onFailure to failWith for unavailable environments and to the update-failure branch. It does not forward onFailure to checkProjectAccess at the pre-loop check and the per-member re-check. checkProjectAccess calls failWith with the default reportProjectFailure.
The picker passes a no-op handler because it shows the error inline. If the user lacks the operate scope, or access is revoked mid-write, the picker still gets the global error toast. The picker also shows the inline alert. The denied and revoked results then reach the picker as a rejection through squashAtomCommandFailure.
Add an optional onFailure parameter to checkProjectAccess and pass it from both call sites in updateProjectGroup. Existing callers, such as removeMembers, keep the default.
Then use checkProjectAccess(members, failureTitle, onFailure) and checkProjectAccess([member], failureTitle, onFailure) inside updateProjectGroup.

The automated pipeline stopped on this pull request and will not merge it:
in the real app the problem is still there, and the rework changed nothing:
No code change. The report says the problem still happens but gives only steps, not the step that fails or what was seen, and I could not reproduce any failure. I ran every step on 02a721f in an isolated web dev stack (T3CODE_DEV_SEED=0, an 'Icon demo' project created with t3 project add, a 1280x800 browser tab). Typing ABCD trims to AB as you type; Save closes the picker and AB is still there on reopen. Pasting full-width ａｂｃ and ｘｙｚ with Ctrl+V gives AB and XY. For the disconnect, I set ZX, closed only the app's /ws socket and blocked it from reconnecting, then clicked Save icon: the picker stayed open, kept ZX and showed the inline error 'Connect and try again.', and was unchanged 6 s later. I repeated this with QW and let the socket reconnect without clicking anything: the picker was still open with the draft and the error. Save icon then saved and closed it, and reopening showed QW (the ZX run also ended with ZX saved). Inserting decomposed áb́c (U+0061 U+0301 U+0062 U+0301 U+0063) as one edit, not a clipboard paste because the clipboard refused writes by then, gave ÁB́ (U+00C1, B, U+0301): two complete graphemes with the combining mark kept, aria-invalid=false, Save enabled and the preview tile drawn correctly. I did not save it, as the steps said. Since the fix behaves as intended on every reported step, I left the branch unchanged. If the reported failure is something else (a visual detail, a different reconnect timing), the report needs to say what was observed.
It stays open for a person to finish or close.
