perf(server): skip non-image results in project icon searches - #32089
Opening the project icon picker requests 200 images but previously converted up to 25,002 native file results before discarding non-images in JavaScript. A workspace containing 10,000 TypeScript files therefore blocked the server while returning no images.
Apply the existing supported-image formats as a case-insensitive native glob before pagination. Preserve fff's original parsing and scoring for lone fuzzy paths and large fuzzy searches with bounded original-query fallbacks. These fallbacks retain the previous 25,002-record ceiling and truncation behavior; ordinary file/folder search is unchanged.
This fits CONTRIBUTING.md's focused obvious-defect exception: remove unnecessary conversion in an existing image-only search, without a new feature, setting, cache or filesystem rescan. No maintainer approval or triage exemption is claimed.
Current modernization verification (2026-11-13, 29f2ff957a60e2f504412c2557617e97cb208a32, upstream main 004f7a768f3f6bba8a4c435b076b7c826448d7ae):
Rebased the original head 881dbf78c397022a4624609d5c025b7391c68f72. Resolved conflicts in the same two workspace-search files; retained main's literal-brace/bracket query handling, host-path behavior, async refresh, and Git ignore filtering. Native search metadata survives visibility filtering so the large-search compatibility decision remains available. Both compatibility paths pass through the shared ignore filter and retain bounded native pages.
Extended the existing native regression for Git-excluded images, literal braces/brackets, brace globs, and the watched-index ranking transition with ignore filtering active. It fails against fetched main at the materialization assertion (255 records versus a 201-record maximum) and passes on the rebased implementation. Focused WorkspaceSearchIndex and WorkspaceEntries suites: 32/32 passed.
Final vp run check:changed refs/modernize/32089/main --concurrency 1: format, lint, both knip checks, GraphQL, three affected package typechecks, and 7 selected tests passed.
Real web client with isolated development state: blank image search excludes a Git-excluded image; literal-brace lookup, non-image glob returning no images, fuzzy path lookup, selection, persistence after reload, and query reset on reopening passed. Desktop, native mobile, relay and tunnel execution were not repeated. No new timing benchmark was taken; the Linux numbers below are historical measurements.
Original validation (retained evidence):
Native regressions failed before their fixes and pass now: image-only materialization, supported formats/case and constraints, tied ranking/truncation, watched-file base/overflow scoring, and the 30,000-match compatibility bound. Final native tests pass 2/2.
vp run check:changed HEAD --concurrency 1 passes format, lint, both knip checks, affected typechecks, and four selected tests.
Linux arm64, Node 26.12.1, pinned fff 0.11, 10,000 source files, empty query/limit 200, ten samples: materialized native records 10,001 → 0; median operation 80.87 → 6.73 ms and scheduled heartbeat delay 80.92 → 6.75 ms. Both return zero images with truncated: false. Ordinary file search stays at 201 materialized records. No x86-64 timing measurement is claimed.
Follow-up 12643d1913b9bc2c83bd88cce5b94eef103c795c fixes CodeRabbit's unbounded compatibility-result finding. This was the pre-modernization compatibility fix.
Historical review-loop verification before this modernization: 4 rounds with GPT-6.1 Sol on verified xhigh effort. Reviewer verdict at that time: approved. Pagination, the watched-index scoring transition and the materialization ceiling are resolved. The fourth round uses the state/concurrency allowance for the evidenced base/overflow transition. The lone-path compatibility-cost nit was declined to preserve native parsing. Usage was not exposed.
Created with GPT-6.1 Sol in the Codex harness, with GPT-6.1 Sol xhigh implementation and review agents.
Takeover verification at 881dbf78c397022a4624609d5c025b7391c68f72: merged then-current main without rebasing; preserved both sides of the test-import conflict. Blacksmith check:changed passed format, lint, both knip checks, affected typechecks and five tests. Two independent Sol xhigh reviewers found no issues. Real Chrome verified image searches, selection, reload persistence and reopening reset. Desktop/mobile were not exercised. Uploaded playback and seeking verified.

Image-only searches now use favicon extension filtering, with fallback handling for lone fuzzy paths and large result sets. Filesystem-backed tests check limits, query forms, tied matches, watched-file updates, and bounded result materialization.
Changes: Image-only search behavior
Layer / File(s)
Summary
Image-only query filtering and fallback apps/server/src/workspace/WorkspaceSearchIndex.ts
Image-only searches use a case-insensitive extension glob, except for lone fuzzy paths, which are filtered after fetching results. If constrained and unfiltered match counts both exceed 15,000, the index uses post-filtering and fetches results up to the page-size cap. Search results preserve additional metadata.
Temporary Git workspace tests cover query forms, limits, tied matches, watched-file updates, ignored images, and bounded result materialization. They also check truncation when a large native result page has no image matches.
pingdotgg/t3code#1000: Adds Git exclusion constraints to the same native query path that applies the image extension constraint.
pingdotgg/t3code#24578: Adds symlink aliases to indexed search results, which are subject to image filtering and limits.
Suggested reviewers:juliusmarminge, t3dotgg
Merge Risk: Low · previous review 29f2f
Image-only project icon searches now skip non-image results while keeping the bounded fallback behavior. The remaining risk is a test that can fail intermittently in CI because it subscribes to file watching before the watcher is ready; it does not affect production behavior.

Explanation
The title names the main change: image-only project icon searches now skip non-image results before pagination, which is a performance fix. It uses the conventional commit format and is specific enough for a teammate scanning history. The changeset matches it: a case-insensitive image glob constraint in WorkspaceSearchIndex.ts, plus tests covering image filtering.
Full details: Description check
Explanation
The description follows the repository template closely. It has the Problem, Change, Scope, and Verification sections. The Problem section states the defect: opening the project icon picker converts up to 25,002 native file results before discarding non-images, which blocks the server. The Change section explains the case-insensitive native glob for supported image formats applied before pagination, plus bounded fallbacks for lone fuzzy paths and large fuzzy searches. The Scope section explains why the change is a focused obvious-defect fix under CONTRIBUTING.md, with no feature, setting, cache, or rescan, and it states that no maintainer approval is claimed. The Verification section gives concrete native regression results, lint and typecheck runs, and a Linux arm64 benchmark with before and after numbers (10,001 to 0 materialized records; 80.87 to 6.73 ms median). It also lists browser checks and the unverified areas (desktop, mobile, x86-64 timing). The template's agent attribution line is present (model and harness named). Minor gaps: the description is long and includes historical and takeover notes that dilute the focus. Some evidence is linked to external URLs rather than embedded. The Scope section does not link a specific issue that shows the bug. These gaps are non-critical, so the check passes.

Merged current main into the existing head in 881dbf78c397022a4624609d5c025b7391c68f72, resolving the test-import conflict while preserving both native-image and host-process coverage. The diff remains limited to the original two files.
Blacksmith vp run check:changed refs/remotes/github/main --concurrency 1 passed format, lint, both knip checks, affected typechecks, and 5 tests. All 31 reported checks pass; GitHub reports MERGEABLE / CLEAN. Two independent Sol xhigh reviews found no issues on this SHA. Both existing bot threads are resolved. The withdrawn unbounded-results request would undo the baseline 25,002-record cap; that cap and truncation remain intact.
Real Chrome verification passed empty-image results, populated searches, png filtering, fuzzy path search, selection, persistence after reload, and reset on reopening. Desktop and mobile clients were not exercised. Uploaded recording playback and seeking were verified.

Wait for watcher readiness before subscribing.
WorkspaceSearchIndex.make(largeCwd) returns after waitForIndexReady() sees the scan finished and warmup complete. That check does not include watcher state. In fff v0.11.0, the scan clears scanning before it installs the background watcher. The watch() call at line 182 can therefore return WatcherNotReady. Line 187 then fails the test, even though searches succeed.
The race depends on timing, so the test can fail intermittently in CI.
A readiness wait must not use polling. The fff v0.11.0 API exposes isWatcherReady only through the polled getScanProgress() snapshot, and the testing rules forbid sleep or polling waits. Choose a non-polling readiness signal before adding the subscription barrier.

Keeps main's symlink merge and asynchronous fff searches, applies the image
glob and its lone-path and filename-fallback paths on top, and trims the
image-search test to the cases that fail when one of those paths is removed.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
On the same Linux x86_64 machine, seeded 10,000 .ts files in 100 directories with zero images. Opened Settings → Projects → ws → Choose file, empty query, with a full page reload before every search. Measured 21 warm real-server WorkspaceSearchIndex.search spans per commit.
The median improved by 69.867 ms (13.22×), exceeding both full run spreads: 29.310 ms before and 5.254 ms after. Both versions showed “No image files found.”
Timings measure the real server search issued by the UI, not total render latency or historical synchronous heartbeat delay. Environment: Node 26.13.1, Chromium, 1280×800 CSS viewport, light theme.
Not shown:
Historical Linux arm64 benchmark figures were not remeasured; this comparison ran on Linux x86_64.
Native materialized-record counts, heap growth, and event-loop blocking were not instrumented; evidence measures real server search duration.
Nonempty queries and workspaces containing supported images were outside this zero-image reproduction.
