Problem

Monograms were exposed to application code as an optional Lucide field, while shared contracts maintained a grapheme counter for Hermes. Moving directly to a new wire discriminant would break older clients.

Change

Use { kind: "monogram", text, color } internally and validate the two-grapheme limit on the server with Intl.Segmenter. Remove the shared counter.

At serialization boundaries, encode monograms as { kind: "lucide", name: "folder-code", color, monogramText }. Older clients ignore monogramText and render the fallback. The old optional monogram field is deliberately omitted so older Unicode validators cannot reject the text. Updated clients decode this representation and the recent nightly lucide.monogram representation into the standalone variant.

Snapshots, outgoing commands, persisted events, and projections retain a legacy-compatible representation. Older servers can drop the unknown text field, leaving the fallback icon; preserving a custom monogram requires an updated server. No capability negotiation or database migration is needed.

Validation

  • Focused tests cover old-client decoding, new-client round trips, complex Unicode, nested snapshots and commands, and persisted event/projection representations.
  • Server typecheck passes after the compatibility change.
  • No new browser or simulator pass for this representation change.

Model: GPT-6. Harness: Codex.

Summary by CodeRabbit

  • New Features

    • Added standalone project monogram icons with customizable text and color.
    • Project monograms now appear consistently in favicons, settings, and icon pickers.
    • Existing icon data remains compatible across current and older clients.
  • Bug Fixes

    • Restricted monograms to valid text containing no more than two grapheme clusters.
    • Improved persistence and display of project icon changes, including legacy monogram data.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This cross-layer refactor changes the project-icon contract, persistence wire format, server validation, and settings UI. The picker can still submit a three-grapheme monogram that the server rejects after the dialog closes, causing the entered value to be lost.

📝 Walkthrough

Walkthrough

Project icons now use a standalone monogram variant. The contract supports legacy decoding and Lucide fallback encoding. Server validation limits grapheme clusters. Persistence, projection tests, and web components use the new shape.

Changes

Project monogram icon flow

Layer / File(s) Summary
Project icon contract
packages/contracts/src/orchestration.ts, packages/contracts/src/orchestration.test.ts
ProjectIconOverride normalizes legacy monogram fields, encodes standalone monograms as folder-code icons with monogramText, and covers client compatibility.
Server monogram validation
apps/server/src/orchestration/decider.ts, apps/server/src/orchestration/decider.projectScripts.test.ts
Project metadata updates reject monograms with more than two grapheme clusters. Tests cover valid and invalid Unicode sequences.
Persistence and projection wiring
apps/server/src/persistence/Layers/OrchestrationEventStore.ts, apps/server/src/orchestration/Layers/ProjectionPipeline.test.ts
Event persistence encodes project icons. Projection tests verify the serialized event and projected icon values.
Web icon handling
apps/web/src/components/ProjectFavicon.tsx, apps/web/src/components/settings/ProjectIconPickerDialog.tsx, apps/web/src/components/settings/ProjectSettingsPanel.tsx
Web components detect, save, render, and describe standalone monograms.

Entering a three-grapheme monogram closes the picker and loses the entered value when the server rejects it; users receive only an error toast. Add matching client validation before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Enforce the two-grapheme limit before onSelect.

isMonogramText accepts ABC, so save calls onSelect and closes the dialog. setProjectIcon then receives the value, but the server rejects project.meta.update because the monogram has more than two graphemes. The dialog unmounts, so the entered value is lost.

Proposed fix
+const monogramSegmenter = new Intl.Segmenter(undefined, {
+  granularity: "grapheme",
+});
+
 const monogram = letters.normalize("NFKC").trim().toUpperCase();
-const validMonogram = isMonogramText(monogram);
+const validMonogram =
+  isMonogramText(monogram) &&
+  Array.from(monogramSegmenter.segment(monogram)).length <= 2;

Project monograms move to their own icon variant (pingdotgg#11993). The only conflict
was two independent test blocks appended to contracts/orchestration.test.ts.

Merges `pingdotgg/t3code` at `0bf2d6b01` into the fork, from base
`5623089ae` — 45 upstream commits.

`255` files landed against `251` changed in the upstream range; the gap
of 4 reconciles exactly (five landed-not-in-range — the three fork docs
and the two fork-only files the typecheck fix touched — against one
in-range-not-landed, `SidebarChrome.tsx`, whose resolution is
byte-identical to `HEAD^1` because the fork's wordmark decision stands).
Fork delta against upstream is now 776 files.

Four conflicts, each resolved with the verdict `preflight.mjs` printed:

| Path | Verdict | Resolution |
| --- | --- | --- |
| `AGENTS.md` | `decide` (`agent-instructions`) | fork's rewrite kept;
upstream's new sentence folded into the existing bullet |
| `apps/web/src/state/threads.ts` | unlisted → `decide, then add an
entry` | the fork's `adoptedEnvironmentSnapshotAtom` graft moved up to
upstream's new snapshot argument (pingdotgg#8309) |
| `ProjectSettingsPanel.tsx` | unlisted → `decide, then add an entry` |
took upstream's `monogram` arm and its required `projectName`; kept the
fork's flag read and Workspace sections |
| `SidebarChrome.tsx` | `decide` (`sidebar-brand`) | upstream
reintroduced `T3Wordmark`; the fork's single `APP_BASE_NAME` span stands
|

`pnpm-lock.yaml` did not conflict this time. Owned-concern sweep: 2 of
27 upstream additions hit the pattern
(`client-runtime/src/connection/compatibility.ts` and its test —
upstream's own protocol check extracted whole by pingdotgg#11990, accepted
unmodified), plus the `@clerk/expo` patch rename at R100 with identical
content. Unsupported methods: ADD 0, DROP 0; 99 of 157 methods declare,
KEEP 2, five known exceptions unchanged.

## Usable as-is

- **Queue-or-steer follow-ups** (pingdotgg#11964, pingdotgg#11673). `followUpBehavior`
lands in `ClientSettingsSchema`, not `ServerSettings` — the queue is
client-side and a steer is an ordinary send, so this needs nothing from
the backend.
- **Monogram project icons** on the project page (pingdotgg#11845, pingdotgg#11993,
pingdotgg#11984), which ride `project.meta.update`. Note this is the *project*
surface only; see the Workspace caveat below.
- `a5da32750` cached turns and older-page loading (pingdotgg#8309); `3efdcc529`
diff tree order and collapsed folders; `9ea892e3b` thread state before
remote replies.
- Desktop fixes: `96bddf812` paste-as-text, `b20d29dc4` double startup,
`c1b221041` sidebar alignment.
- Web polish: `f0a0ead94`, `9a6b57be2`, `bf3be75c4`, `3c4c9a125`.
- `37a8ab2b2` Hermes API ban lint rule; `87a12b53f` usage-limit refresh.
- Dependency bumps: `844203d4f` Clerk, `b18a560bb` Reanimated/Worklets.
Mobile fixes land inert.

## Unsupported in Moatless / needs implementation

- **Monograms on Workspace icons.** This is the one upstream change that
broke something. `ProjectIconPickerDialog` is upstream's, the fork's
Workspace settings page borrows it, and upstream gave monograms their
own `ProjectIconOverride` arm — but the Workspace API's `WorkspaceIcon`
has only `lucide` and `emoji`, so there is no field for the letters.
`workspaceIconFromOverride` now returns `null` for a monogram, which
saves as no icon: the same automatic glyph the project drew before the
pick. Hiding the mode instead would mean threading a prop into an
upstream component, which the Stable Fork Rules exist to avoid. Recorded
in `docs/fork/gaps.md`, *Workspace icons cannot hold a monogram*; it
closes when the Workspace API's icon schema grows a monogram arm and
`packages/moatless-api/src/generated/model/workspaceIcon.ts`,
regenerated, carries it.
- Everything behind `FEATURES.connections: false` — pingdotgg#11990 discovery
compatibility, pingdotgg#11974 and pingdotgg#11862 mobile connection gating — lands inert.
- `b84f63bb1` legacy-launcher update blocking and `e6ae764f4` mobile v2
store builds are outside what this fork ships.

## Backend behavior to consider reproducing in Moatless

Eight upstream server fixes, all added to `docs/fork/gaps.md` under
*Runtime fixes upstream made to its own server*:

- pingdotgg#11954 — rewind against history whose length changed.
- pingdotgg#10792 — checkpoint capture reuses index metadata.
- pingdotgg#11633 — fetch/checkout correctness.
- pingdotgg#11405 — git processes capped at 8 by a semaphore, **with long
operations exempt**. The exemption is the easy half to miss; capping
without it stalls clones behind short status calls.
- pingdotgg#11381 — preview host released after an unanswered request.
- pingdotgg#11345 — a missing provider executable names the setting that points
at it.
- pingdotgg#12008 — health checks clean up `_MEI` folders.
- pingdotgg#11888 — GitHub GraphQL budget, rate-limit gate, and read cache.

Also worth noting: with `followUpBehavior: "steer"` a message is
dispatched mid-turn, which touches the existing gap *A message sent
during context compaction should be queued, not dropped*.

## Verification

`verify.mjs` — tripwires, resolution-check, unsupported-methods,
fmt:check, lint and typecheck all green; full test pass run sequentially
by package. Two caveats, both pre-existing and neither from this merge:

1. **`@t3tools/desktop` fails `scripts/browser-secret-native.test.mjs`**
— it shells out to `pkg-config` for `libsecret-1`, which the sandbox
does not have. The file is not in the merge diff and 106 of its 108
suites pass (1365 tests, 12 skipped). Standing entry in `gaps.md`.
2. **`duplicate-adds.mjs` exits 1 on
`packages/contracts/src/orchestration.test.ts`** — a false positive. The
fork's script-port test (line 644) and upstream's new monogram test
(line 1538) share `const command = yield* decodeOrchestrationCommand({`
and `assert.strictEqual(command.type, "project.meta.update");` at
different indentation, and the script trims whitespace before comparing.
Both tests are wanted; no edit is correct, and typecheck and lint both
pass over the file. The next merge's base moves past it.

## Inventory: a hole that this merge closed

`resolution-check.mjs` listed seven paths both sides changed with no
`pathPolicy` entry. Every one of them carries a real fork delta, which
means next merge's `theirs` fallback would have dropped it silently. All
seven are now covered — four entries extended and four added
(`branch-toolbar-gates`, `thread-adoption-graft`,
`project-settings-panel`, `git-vcs-driver-core-test`).

The last of those is the one worth reading:
`apps/server/src/vcs/GitVcsDriverCore.test.ts` is **the fork's only
delta in `apps/server` outside `auth.ts` and `rpc.ts`** — an SSH-wrapper
test rewritten to intercept `ChildProcessSpawner` because the sandbox
has neither a reliable `ssh` nor an executable temp dir — and it was
recorded nowhere.

`resolution-check` now reports 25 paths checked and each still differs
from upstream, 19 `theirs-verbatim` paths byte-identical to upstream,
and no unlisted paths both sides changed. `tripwires.mjs` reports `ok 3
active workflow(s), all allowed` — the previous merge's off-repo action
has been done, and **no off-repository action is outstanding for this
merge**.
