The /omfg generated-rule path validated conditions with raw new RegExp in normalizeConditionRegex and isValidRegexCondition, so a generated rule with a leading (?i)/(?m)/(?s) inline flag was rejected as "Invalid condition regex" before reaching TtsrManager.addRule. Route all three validation sites through compileRuleCondition.
Fixes#4796
The /todo rm reminder was a generic "user manually modified" message
showing an empty list, so the model read the cleared list as missing and
re-populated it on the next turn. buildSystemReminder now emits an explicit
do-not-recreate / do-not-re-add directive for removals while keeping
status mutations (done/drop) neutral.

Resolves the two Codex P2s raised on #4420 that merged unaddressed:
- wrapUrlRows indented every continuation chunk. A multi-row terminal
selection includes the newline plus that indent; address bars strip
newlines but preserve or percent-encode embedded spaces, so the
reassembled URL was corrupted at every chunk boundary - silently,
when the damage landed inside a query value. Chunk rows now carry
zero leading bytes (label rows keep their indent), and the test
reassembly helper concatenates chunks raw instead of stripping the
indent that previously masked exactly this defect.
- #launchUrlIfSafe advertised a localhost /launch copy target for
flows whose redirectUri never returns to the loopback server. Its
catch-comment assumed custom-scheme URIs are non-parseable, but
new URL('vscode://gitlab.gitlab-workflow/authentication') parses
fine and sailed through the pathname check. The guard now requires
an http(s) loopback redirectUri (localhost / 127.0.0.1 / [::1]);
custom schemes, non-loopback hosts, and unparseable URIs all
suppress the launch URL. Regression tests cover the GitLab Duo
vscode:// shape and a fixed non-loopback HTTPS redirect.

- Added test case for parsing and falling back comma-delimited model patterns.
macOS laptops have no dedicated Forward Delete key. Fn+Backspace is the
only way to send \e[3~, and many macOS terminals (Terminal.app, some
iTerm2 profiles) deliver \x7f for that combo instead — so the keystroke
landed in the search box, not the delete handler, making session deletion
unreachable for those users.
Add a Backspace-on-empty-search handler alongside the existing Delete
check. With a typed query, Backspace stays bound to the search Input so
users can still edit their filter text. The existing confirmation dialog
guards against accidents.
Footer hint updated: [Del delete] -> [Del/⌫ delete].
- Mocked messagePersistenceKey in event-controller-error-banner.test.ts and safe-guarded it in event-controller.ts to prevent TypeError.
- Updated thinking loop retry test expectations to handle new dynamic recoveredErrors structure.
- Updated schema version assertions in auth-storage-email-dedupe.test.ts to v5, preserving v6 for future schema test.
- Simulated scrollback commitment in event-controller-message-start.test.ts by rendering container and committing rows before advancing timers.
@DylanBohlender's follow-up caught that MCPAuthorizationLinkPrompt.render
still ignored `width` and emitted `Copy URL: <full URL>` as one composed
row. On any viewport narrower than the row (~272 columns for a
Linear-shaped authorize URL), TUI#prepareLine's
`truncateToWidth(..., Ellipsis.Omit)` silently clipped the trailing
`code_challenge_method=S256` — the exact #4418 fingerprint reappearing
inside the remote-safety fix. A remote user on a narrow terminal
copying the rendered line would lose the S256 method again; the local
shortcut below cannot help them (localhost isn't reachable), and the
OSC 52 clipboard staged full URL isn't visible in their local browser.
Component-level fix: honor `width` in render.
- New `wrapUrlRows(label, url, width)` helper.
- When `label + " " + url` fits in `width`, emit one inline row.
- Otherwise emit the label on its own row and slice the URL into
chunks of `width - indent`, each on its own row.
- Floors the effective width at 16 columns so degenerately narrow
terminals still emit every character; browsers strip whitespace
when a multi-row selection is pasted into the address bar, so the
reassembled URL is byte-identical.
- `render(width)` now uses the helper for both the primary `Copy URL:`
row and the additive `Local shortcut (this machine only):` row.
Regression tests in
`packages/coding-agent/test/modes/controllers/mcp-authorization-link.test.ts`:
- Wide viewport (1000 cols): inline `Copy URL: <url>` layout preserved.
- Narrow viewport (80 cols) + Linear-shaped URL: every row's visible
width ≤ 80, and the chunks reassemble byte-for-byte to the URL —
explicitly asserting the trailing `code_challenge_method=S256`
survives.
- Launch shortcut also wrapped at 80 cols; every row fits.
- Degenerate viewport (4 cols): URL still reconstructs exactly; the
16-col floor governs chunk width.
- Full URL remains the primary target even when a launch URL is
present, and the shortcut row is omitted when launchUrl is absent
or identical to the full URL.
Codex review flagged that advertising `launchUrl`
(http://localhost:<omp-port>/launch) as the visible `Copy URL:` breaks
SSH/WSL/headless users: their local browser resolves the URL against
the local machine (no OMP listening) and fails before ever hitting the
provider. On terminals without OSC 8 support, they lose the manual
`/login <redirect>` path entirely.
Every OAuth-facing surface now shows the full authorization URL as the
primary copy target and offers `launchUrl` as an additional "Local
shortcut (this machine only)" line for wide-terminal local users who
want the truncation-safe convenience:
- MCPAuthorizationLinkPrompt renders `Copy URL:` with the full URL and
appends the local-shortcut row only when `launchUrl` differs. OSC 52
clipboard staging in the MCP onAuth handler switches to the full URL
(OSC 52 is a wire-level protocol — the terminal writes to the
caller's LOCAL clipboard even when OMP is on a remote SSH box).
- LoginDialogComponent.showAuth, selector-controller onAuth,
setup-wizard sign-in, and the auth-broker CLI mirror the pattern:
full URL first, launchUrl as an optional local shortcut.
- Setup wizard uses `wrapTextWithAnsi`, not truncation, so the RFC
7636 §4.3 downgrade bug that motivated launchUrl is unreachable
through it; still surfaces launchUrl for wide-terminal convenience.
Regression tests in
`packages/coding-agent/test/modes/controllers/mcp-authorization-link.test.ts`
now assert:
- Full URL is the primary `Copy URL:` line so SSH sessions can complete.
- launchUrl still appears beneath as `Local shortcut (this machine only): …`
when it differs from the full URL.
- No shortcut row when launchUrl is absent OR equals the full URL.
Two independent defects broke /mcp reauth against S256-only providers on
Windows boxes whose PATH no longer references System32:
1. openPath spawned bare rundll32 and swallowed the
`Executable not found in $PATH` throw with a bare `catch {}`, so the MCP
controller's outer try/catch was dead and the transcript unconditionally
claimed "Opening browser automatically...".
2. TUI#prepareLine silently truncates any composed row wider than the
viewport. MCPAuthorizationLinkPrompt rendered `Copy URL: <full URL>` as a
single ~271-column line whose trailing parameter is
code_challenge_method=S256. On the reporter's 270-col terminal the cut
landed inside that parameter, dropping the method while keeping
code_challenge — which RFC 7636 §4.3 treats as plain PKCE, which Linear
correctly rejects with "The plain PKCE method is not allowed. Use S256
instead."
OAuthCallbackFlow now hosts a `GET /launch` route on the same loopback
callback server it already runs; the route 302-redirects to the pending
authorization URL and is advertised as `OAuthAuthInfo.launchUrl` — a
~30-char copy target no viewport can meaningfully truncate. The MCP OAuth
fallback, /login, setup wizard, auth-broker CLI, and login-dialog all
prefer the launch URL for the visible copy target, keep the full URL in
the OSC 8 hyperlink for click-through, and the MCP flow additionally
stages the copy target on the clipboard via OSC 52 (same pattern the
setup wizard uses).
openPath now resolves rundll32.exe through %SystemRoot%\System32 (with a
C:\Windows fallback when SystemRoot is unset) and logs both synchronous
spawn throws and non-zero exits via the shared logger, so silent
misconfigurations show up in ~/.omp/logs/omp.*.log. The dead try/catch
around openPath in the MCP controller is removed.
Fixes#4418
Four tightly-scoped hot-path fixes covering the highest-impact items in the
reporter's CPU profile (13.1 s profiled / 30 s window):
1. `event-controller.ts:handleEvent` no longer fires a blanket
`statusLine.invalidate() + ui.requestRender()` before every session event.
The pre-render was a leftover from #4145 when `updateEditorTopBorder()`
still eagerly rebuilt the border; the lazy provider added in #4145 made
it redundant. It fired on every `message_update`/`tool_execution_update`
during streaming — the pre-render's frame ran while the handler was
awaiting, then the handler's own `requestRender` scheduled a second
identical frame. Every handler that mutates visible state already calls
`requestRender()`.
2. `shimmer.ts:shimmerSegments` iterates the segment string in place instead
of building a code-point array with `Array.from(seg.text)` every animation
frame. Runs of same-tier chars are emitted via a single `slice` per run
rather than accumulating into `runBuf`. Surrogate pairs stay atomic — the
code-point index still advances by 1 per emoji. Microbench over 30k
frames: 45 ms → 18 ms (2.53x), allocation rate down from ~N-per-frame to
a handful per frame. New tests cover mixed BMP+surrogate and all-emoji
inputs. `Array.from` was the #1 self-time hotspot in the reporter's
profile at 10.2%.
3. `Markdown.setText` gains an equality guard mirroring `Text.setText`
(returns `false` when `text === #text`). Providers re-emit identical text
on ticks with no delta (throttled frames, reconciled tool-execution
updates); each of those now short-circuits instead of dropping
`#cachedLines` and forcing a full lex + wrap on the accumulated paragraph
(the reporter's #3 hotspot at 8.4%). New test asserts render-reference
stability + return-value semantics.
4. `SPINNER_RENDER_INTERVAL_MS` aligned with `SPINNER_GLYPH_ADVANCE_MS`
(both 80 ms). The previous 33 ms cadence emitted ~2.4 paints per glyph
step; the differential-output dedup only skips the write, not the
compose walk. Visually identical (glyph advance was already 12.5fps),
halves paints during tool execution.
Skipped (out of scope for a bug fix, deserve dedicated PRs):
- Freezing streaming prefix on single `\n` boundaries — correctness-bound
to `\n\n` block separators (CommonMark loose-list continuation).
- Compose-phase idle gate + adaptive-backpressure moving-average — need a
component-level dirty flag; the 200 ms cap in `#scheduleRender` was set
for a reason (#4145 tail-latency guard).
Tests updated: two IRC-expiry tests in event-controller-message-start.test.ts
that were asserting the pre-render's second `requestRender` call now expect
one.
Fixes#4353
EventController.handleEvent rebuilt the editor's status-line top border
synchronously on every session event via updateEditorTopBorder(). During
a long-running eval that fires 5-10 events/s, each rebuild ran
StatusLine.getTopBorder → #buildSegmentContext → getCachedContextBreakdown
→ session.getContextUsage → estimateTokens (with JSON.stringify per
toolCall block) — the render pipeline is throttled to ~30 fps, so most
rebuilds were dropped before painting. Combined with a scheduler that
collapsed cadenceDelay to zero whenever a frame overran the 33ms budget,
the TUI busy-looped at ~40-50% CPU.
Fix:
- Editor gains setTopBorderProvider(): a lazy builder invoked once per
editor render. InteractiveMode installs it in the constructor and on
setEditorComponent, so the rebuild coalesces to the render tempo
regardless of event rate.
- Delete updateEditorTopBorder wrapper (now equivalent to
ui.requestRender) and inline every call site.
- Add adaptive render backpressure: a frame that exceeds
MIN_RENDER_INTERVAL_MS inflates the next scheduling delay to
2 * last_frame_cost, capped at 200 ms, targeting a 50% render duty
cycle instead of pinning the CPU at t=0.
New regression tests:
- editor-top-border-provider.test.ts: provider fires exactly once per
render, wins over eager setTopBorder, falls back when cleared, gets
the correct availableWidth.
- adaptive-render-backpressure.test.ts: cheap frames keep the 33 ms
cadence, a slow frame idles proportionally, pathological frames are
capped at 200 ms.
Verified with bun test packages/tui/test (all 246 relevant tests pass)
and bun test packages/coding-agent/test/modes (455 tests pass). Three
pre-existing agent-session-handoff snapcompact failures on main are
unrelated (snapcompactSupportedChars binding).
Fixes#4145
ToolArgsRevealController.setTarget initialized new entries with revealed=0, so the first message_update returned { __partialJson: "" } even when the provider had already parsed a complete chunk. For renderers without exposeRawPartialJson (e.g. write), the throttled re-parse + cached displayArgs short-circuited every subsequent setTarget, leaving the preview body blank until tool_execution_end.
Seed revealed with the full incoming partialJson length on entry creation (clamped to a surrogate-safe boundary). The first frame now carries the parsed path/content immediately; subsequent message_updates extend target and the reveal ticks pace only the newly arrived bytes — no field is ever truncated because the seeded prefix is the longest the entry has seen so far.
Fixes#3881
StdinBuffer held a bare `\x1b\x1b` chunk and timer-flushed it as one
sequence. `parseKey("\x1b\x1b")` returns undefined, so CustomEditor
fell through to the base editor and never fired the configured `onEscape` —
the double-escape gesture and the second-press single-Esc handler both went
dead whenever the terminal batched the two presses into one stdin read.
Split an exact bare `\x1b\x1b` into two ESC events only after the
flush window proves no follower arrived. If a follower does arrive, emit the
first ESC and restart parsing at the second ESC so legacy Alt chords
(`\x1bd`, `\x1b\x7f`) remain one downstream keypress. Meta-CSI/SS3
chords (`\x1b\x1b[A`, `\x1b\x1bO…`) still emit as one combined
sequence.
EventController.tool_execution_update re-armed the working loader when a
transient overlay (auto-compaction / auto-retry / handoff) had torn it down
mid-tool; tool_execution_end did not. A subagent (`task`) call only fires
_end, so a task result landing after such an overlay left the UI looking
idle even though the session was still streaming. Mirror the reconciler
call in #handleToolExecutionEnd.
