Problem

In Add to another machine, a Git project with more than 200 eligible ignored files shows only the first 200. Files after the cutoff cannot be selected for copying. Reproduced on current main with 205 tracked-anchor folders and eligible ignored files through two normally paired isolated environments.

Change

Filter ignored paths by a bounded, case-insensitive search before applying the existing listing limit. Show the search field when the source supports it and the listing is truncated. Preserve selections and their sizes across searches, with All/None applying to shown results and a global 200-file selection limit.

The source capability keeps older servers on the existing picker. Per-file eligibility and copy behavior remain unchanged.

Scope and approval

Fixes #24504

GitCafe: https://git.cafe/pingdotgg/t3code/issues/24504

Triaged bug via the automated issue flow. This fixes the existing ignored-file selection failure; no new copy capability or persisted state. The existing contributor #22844 remains untouched.

Verification

• Regression test failed on main: searching for folder-205 returned only folders 001–200. It passes with this fix.
• All 19 WorkspaceEntries tests pass. Contracts, server and web typechecks pass; changed-file lint and formatting pass.
• Independent GPT-6.1-Sol and Claude Opus 5.5 diff reviews found no confirmed implementation bugs.
• Two real paired servers: a filtered clone copied .env and candidates 204/205 with exact contents (3 files / 31 B). A second filtered clone copied exactly 200 ignored files / 1,607 B, including candidates beyond the cutoff. Unselected and oversize files were absent.
• Runtime checks covered trimmed/case-insensitive queries, debounce, Enter not submitting, selection persistence, shown-only All/None, cap transitions, small/empty lists and size boundaries.

Recordings: Search and three-file clone, selection cap and 200-file clone, query and Enter checks. Narrated steps, timestamps and destination transcripts are in the index.

Visible differences: search field, selection-summary and truncation wording, taller dialog and shifted content. Background timestamps, shadows and caret contribute comparison pixels; the captures do not claim that nothing else changed.

Unverified: actual older source binary (capability branches were synthetic), native desktop shell, hosted/remote-origin/relay/tunnel, exact-1-MiB destination copy. Responsive 390px evidence is web; native mobile has no picker caller. Loading/error checks in the initial bundle use synthetic UI state and do not prove real transport failures. The proof audit identifies missing interaction subcases; Supplemental recordings cover caller reset, whitespace-only query, partial-group and cap deselection, no-match/clear, legacy capability cap, and a real workspace-service failure. Supplemental audit resolves A, C, E, G and the synthetic I cap gap. H remains open: controlled initial/search pending states, fresh initial failure without cached defaults, and search-error clear restoring the original list. The H recording ends on the error, so recovery is not claimed as recorded proof. The I recording does not show the narrated repeat All; its initial exact-cap proof is sufficient. Hosted CI and bot review remain pending; no bugfix handoff label has been applied.

Models: GPT-6.1-Sol through the Codex harness; Claude Opus 5.5 through the Claude Agent harness.

Walkthrough

The server now filters ignored-file paths by an optional case-insensitive query before applying its listing limit. The machine-copy dialog supports search when the source advertises the capability, retains selections across search results, and limits selections to 200 files.

Changes: Ignored-file search and selection

Layer / File(s)	Summary
Query contract and server filtering packages/contracts/src/project.ts, packages/contracts/src/environment.ts, apps/server/src/environment/ServerEnvironment.ts, apps/server/src/workspace/WorkspaceEntries.ts, apps/server/src/workspace/WorkspaceEntries.test.ts	The request accepts an optional query of up to 256 characters. The server advertises search support and filters paths before applying its listing limit. A test checks that a match beyond 200 candidates is returned without truncation.
Dialog search and selection state apps/web/src/lib/addProjectToMachine.ts, apps/web/src/components/AddProjectToMachineDialog.tsx	The dialog debounces supported searches and stores selected file records by path. Default selections come from the full listing.
Selection limits and clone submission apps/web/src/components/AddProjectToMachineDialog.tsx	The dialog caps selection at 200 files, updates selections from displayed rows, shows counts and search states, disables rows when the limit is reached, and submits selected paths.

Full details: Title check

Explanation

The title names the fix and the area it touches. The change makes ignored files past the 200-file copy picker cutoff findable through a case-insensitive search, which matches the title's point. The title uses the conventional commit form and avoids file lists or vague terms.

Full details: Description check

Explanation

The description follows the template sections (Problem, Change, Scope and approval, Verification). It explains the 200-file cutoff problem and the search-based fix, and links issue #24504 with a triage note. Verification lists focused tests, typechecks, lint, and paired-server runs, with before/after evidence and unverified items stated. The title follows the template's conventional commit guidance. The description is long and includes many external evidence links, but the required content is present and specific.

Full details: Linked Issues check

Explanation

Directly linked issue #24504 requires that users find and select eligible ignored files beyond the first 200 candidates, while keeping the 200-file selection limit and the 1 MiB per-file limit. The whole-PR summary shows the server applies the optional query as a case-insensitive substring filter before sorting and the 200-file cap (apps/server/src/workspace/WorkspaceEntries.ts). A regression test creates 205 ignored files and queries for FILE-205 (WorkspaceEntries.test.ts). The web dialog (AddProjectToMachineDialog.tsx) sends trimmed, debounced queries, keeps selections across searches, applies All/None to shown results, and enforces COPIED_FILES_MAX_COUNT and COPYABLE_FILE_MAX_BYTES. The contracts add the optional query field and the ignoredFileSearch capability. The incremental diff since b703db7 that I inspected touched CI, tooling, and docs files only; it did not show changes to the feature files. That diff output was truncated, so the feature-file state at head is taken from the whole-PR summary. Wholly ignored folders remain excluded by the existing Git listing. The issue's broader expectations about paging were not required, since the issue's expected behavior is satisfied by search.

Full details: Out of Scope Changes check

Explanation

The incremental diff from b703db7 to 1e825cc adds changes that do not implement issue #24504. These include: .github/scripts/test-delta.cjs and its test, plus a new 'Report test suite growth' step in .github/workflows/pr-size.yml that posts or edits PR comments; sharding of test_web into two matrix shards in ci.yml and release.yml; a Vitest module cache restore and save in ci.yml; and changes to .macroscope/check-run-agents/ui-consistency.md and AGENTS.md. None of these change ignored-file listing, search, or selection behavior. The PR description does not mention CI, PR-size reporting, or agent-guidance changes. The incremental diff output was truncated at 16000 bytes, so further unrelated files may exist that I did not read. The whole-PR change set was not fully enumerated.

Resolution

Remove the CI, PR-size, test-delta, Vitest cache, release sharding, AGENTS.md, and macroscope documentation changes from this PR, or move them to a separate PR with its own scope. Keep the ignored-file search changes in apps/server, apps/web, and packages/contracts, plus their tests. Then confirm that the whole-PR file list against the merge base contains only files related to issue #24504.

Evidence

Steps: Prepare 205 tracked folders with ignored local.secret files. Connect a destination environment and open Add to another machine. Find folder-205, select its file, find folder-204 and select its file, clear search, then clone and inspect both destination files. Base stops at the missing folder-205 assertion; head completes the flow.

Environment for every capture: Chromium, 1280x800, light theme; fresh isolated source and destination servers running the commit shown. Synthetic workspace paths are hidden.
