* feat(backend): plan revision history with checkpoint/revert
Persist every plan edit as an immutable TaskPlanRevision with author
attribution (agent vs user) and expose WS actions to list, fetch, and
revert to past revisions. Emits task_plan.revision.created and
task_plan.reverted events so the UI can react in real time.
* feat(web): plan revision history UI with rewind to past versions
Add a rewind button to the plan panel that opens a revisions list
showing each checkpoint with author (agent name or user) and timestamp,
and lets the user restore any past revision as the new head. Plan
state, hooks, and WS handlers are extended to load, cache, and react
to revision-created/reverted events.
* test(web): e2e coverage for plan checkpointing and rewind
Cover the full revision flow: plan edit creates a checkpoint,
the revisions panel lists authors and timestamps, and reverting
restores the selected revision as the new head. Extends session
page object and backend fixtures with revision-related helpers.
* fix(web): stabilize plan revisions state and avoid re-render loop
Zustand selector returned a fresh [] for missing revisions, fanning out
re-renders that tripped React's infinite-loop guard when the plan panel
mounted. Swap to a frozen empty-array sentinel, auto-load revisions on
mount so WS events fired before connect aren't lost, and gate the
popover's on-open fetch so reopening doesn't re-sort rows mid-click.
* test(web): make plan checkpointing e2e resilient to agent auto-layout
Agent-authored plan writes auto-open the plan panel and can push the
chat tab inactive, so the chat idle placeholder isn't always visible
once the agent finishes. Accept either chat or plan panel as the idle
signal, make openPlanPanel and openRewind idempotent, reopen the
popover after a revert cancel (the confirm dialog closes it), and drop
the toast assertion since no Toaster is mounted in the app.
* fix(backend): atomic plan revision write + review polish
- Add `WritePlanRevision(ctx, head, rev, coalesceLatestID)` repository method
that wraps HEAD upsert + MAX+1 compute + insert/merge in a single write tx,
closing the TOCTOU race on `revision_number` and partial-failure divergence
between HEAD and history. `upsertPlan` and `RevertPlan` both route through it.
- Add `ErrRevisionIDRequired`; return it for empty `TargetRevisionID` (was
previously conflated with `ErrRevisionNotFound`). Handler maps to validation.
- Backfill fallback `author_kind` changed `"user"` → `"agent"` to match
`CreateTaskPlan` and the column default.
- Extract shared `revisionSelectCols` constant; rename `max` local (shadowed
Go builtin) and `dto` local (shadowed package name).
* fix(web): address plan-revisions review feedback
- `mcpWrite` uses `JSON.stringify(content).slice(1, -1)` to escape backslashes,
quotes, and control chars in one pass — closes the CodeQL finding.
- `clearTaskPlan` now evicts `revisionContentCache` entries for the task's
revisions before dropping the maps, preventing orphaned cache growth.
- `RevertConfirmDialog` wraps `onRevert` in try/catch/finally so rejections
surface a toast and the dialog always dismisses.
- Hoist `TaskPlanRevision` import in `task-plan-panel.tsx`.
- `RevisionRow` derives relative time from props every render with a 30s tick,
so prop changes refresh immediately.
- Strengthen author-switch e2e with `.not.toBeEmpty()` to also reject empty or
truncated renders.
* fix(web): evict revision content cache on coalesced update
Coalesced writes update an existing revision's content on the backend, but
the WS `upsertPlanRevision` payload carries only metadata. Without eviction,
a cached preview of the revision stays stale after the agent re-writes the
plan within the coalesce window.
* fix(web): plan history UI polish from local testing
- Drop the redundant "Plan" title in the panel header bar; the dockview/mobile
tab already labels the panel.
- Author display: show "You" with the user icon for user-authored revisions,
and the agent profile name with the AgentLogo (resolved from the active
session's `agent_profile_snapshot.agent_name`) for agent revisions, matching
the icon used elsewhere in the app.
- Replace ScrollArea with a plain `max-h-96 overflow-y-auto` div so the
popover stays bounded when revision counts grow past ~7 rows.
- Drop the em dash from the revert dialog description.
* feat(web): add lineDiff helper for plan revision compare
Tiny wrapper around the `diff` package that classifies each line as add /
remove / context and strips the trailing-newline phantom entry. Also exposes
`diffSummary` for the dialog header counts. Pure functions; backed by Vitest.
* feat(web): plan revision preview + compare state
Adds two task-scoped store keys for the new dialogs:
- `previewRevisionIdByTaskId` — at most one open preview per task; cleared on
`clearTaskPlan`.
- `comparePairByTaskId` — ordered 2-slot pair. `toggleComparePair` reuses a
`nextPair` helper that handles unselect (already-picked id), fill (open
slot), and FIFO eviction (full pair). `clearTaskPlan` resets it too.
* feat(web): plan revision preview + diff dialogs
- `useTaskPlan` exposes `previewRevisionId`, `setPreviewRevision`,
`comparePair`, `toggleCompareSelection`, `clearComparePair` (extracted into
`usePreviewCompareState` to keep the surrounding hook within the size cap).
- New `PlanRevisionPreviewDialog`: read-only modal for a single revision with
Restore + "Compare with current" CTAs. Restore routes through the existing
RevertConfirmDialog so the confirmation copy stays consistent.
- New `PlanRevisionDiffDialog`: line-level unified diff between two revisions
with adds/removes highlighted; orders the pair by revision_number so the
older one is always "before"; Restore targets the older side.
- Popover row split into a clickable body (opens preview), a Compare toggle
(icon button per row), and the existing Revert button. Compare chips appear
at the top of the popover with a Diff CTA when both slots are filled.
- Both dialogs are remounted via key on revision/pair change so loader state
resets without ESLint-flagged setState-in-effect resets.
* test(web): e2e coverage for plan preview and compare-diff dialogs
Extends the SessionPage POM with locators for the new preview and diff
dialogs (chips, compare toggle, restore buttons, body + summary). Adds two
scenarios in plan-checkpointing.spec.ts:
- Click a revision row body → preview shows the right content; the Restore
CTA opens the existing confirm dialog and the revert lands.
- Toggle compare on two revisions → diff opens with v1 → v2 ordering and
shows at least one add and one remove line; the Restore CTA targets the
older side.
* feat(web): render markdown in plan preview + diff dialogs
Adds a shared `PlanReadOnlyMarkdown` Tiptap renderer that reuses the same
StarterKit + tiptap-markdown + tables/tasks/code-block extensions as the live
plan editor (minus interactive bits — slash menu, drag handles, comment
marks). Wired into both dialogs:
- Preview replaces the raw `<pre>` block with the rendered Tiptap view.
- Diff dialog now stacks two rendered sides (Before / After) with red/green
tinted borders, kept above the existing line-level breakdown so the user
gets both rendered comparison and an exact textual change list.
Tiptap doesn't ship a free diff/track-changes extension (it's part of Tiptap
Pro), so the side-by-side rendering plus the line-level list together stand
in for that.
* fix(web): plan diff dialog — text-only with unified/split modes
Following local feedback:
- Drop the rendered-markdown side-by-side panes from the diff dialog. Diff
view is text-only again, like a code review.
- Add a Unified / Split mode toggle. Split mode aligns each remove with the
adjacent add on the same row (single-line edits stay paired) and stripes
empty cells where one side has nothing.
- Fix the highlight-truncation bug: long lines used to lose their tinted
background past the viewport on horizontal scroll because the row width
was capped to the visible area. Rows now use `min-w-full w-max` so the
background extends through the full scroll width.
Preview dialog keeps the rendered Tiptap markdown — only the diff reverted
to plain text.
E2E covers both modes and the cell kinds.
* feat(web): formatPreciseTime util for minute-level timestamps
Returns 'just now', 'Xs ago', 'Xm ago' for the first hour, then 'Today, HH:MM',
'Yesterday, HH:MM', or '{Mon} {DD}[, YYYY], HH:MM' for older entries — keeps
exact minute-of-day visible instead of decaying to 'yesterday'/'2d ago'.
* fix(web): render markdown via setContent in plan read-only renderer
The tiptap-markdown extension's parser only fires on `setContent` calls, not
on the initial `content` option. Passing `content: value` to `useEditor` was
treating the markdown source as raw text, so the preview dialog rendered
unparsed markdown.
Drop the `content` option and instead call
`editor.commands.setContent(content, { emitUpdate: false })` from a useEffect
once the editor is created — which is what the live plan editor effectively
relies on through tiptap-markdown's setContent override.
* fix(web): plan history UX — bigger modals, split layout, simpler compare
- Bump dialog widths: preview now `max-w-5xl w-[92vw]`, diff
`max-w-6xl w-[95vw]`, both with taller max-height. Plenty of room for
rendered markdown and side-by-side diffs.
- Replace the table-based split layout with a CSS grid (`grid-cols-2 w-max`).
The table-fixed cells were overflowing into each other when content was
wider than half the dialog; the grid lets the natural width drive a single
horizontal scrollbar on the parent and keeps the two columns properly
separated.
- Switch row timestamps to `formatPreciseTime` so users see minute-of-day
("Today, 14:32", "Yesterday, 09:14", "Apr 21, 11:08") instead of decaying
to "yesterday".
- Simplify the compare flow: drop the per-row Compare toggle, the chip strip
at the top of the popover, and the standalone "Diff" button. Compare is
now a side effect of preview — open any version, then click "Compare with
previous" or "Compare with current". E2E test updated to use the new path.
* test(web): update plan checkpointing e2e for the new compare flow
Drops the locators for the row Compare toggle, chips, and standalone Diff
button (those UI bits are gone). Adds a locator for the new
"Compare with previous" preview button. The compare scenario now opens the
diff via preview → "Compare with current" instead of the old chip flow.
* fix(web): preview renderer reuses live editor's markdown styles
`globals.css` keeps heading sizes / list spacing / code-block padding under
.markdown-body and .tiptap-plan-wrapper, and the live editor opts in by
applying both classes (plus a conditional .dark for theming). The read-only
renderer was using `prose prose-sm` instead, which doesn't actually take
effect on the .ProseMirror node — leaving everything the same size.
Switch the read-only renderer to the same class set, follow the live
editor's `useTheme` -> `dark` pattern, override `!h-auto` so the renderer
sizes to its content, and trim the editor's default 0.75rem padding inside
the dialog body.
* fix(web): split diff has fixed width with synced horizontal scroll
The previous split layout grew the whole dialog wider when content overflowed
which felt wrong. Now:
- The dialog stays at its fixed width.
- Each pane has its own `overflow-x-auto` so each side is capped at half the
dialog and gets its own horizontal scrollbar.
- A scroll listener keeps both panes' `scrollLeft` in lockstep (with a
re-entrancy guard so the bounce-back doesn't form a loop) — corresponding
rows stay aligned visually no matter which side the user scrolls from.
- The diff body's overflow-x is hidden in split mode (the panes own it) and
only overflow-y stays on the body so vertical scroll covers both panes
at once.
* feat(backend): resolve agent profile name from session for plan revisions
The MCP-side handlers (handleCreateTaskPlan / handleUpdateTaskPlan) don't
carry the agent's display name in the request, so without a lookup every
agent-authored revision was rendering as the literal "Agent" fallback in
the history UI.
PlanService now looks up the task's session and reads the agent profile
display name from `agent_profile_snapshot` (preferring "label", then
"name", then "agent_display_name") when the request is an agent write
without an explicit author_name. Active session is tried first; falls
back to the most recent session by started_at so plans written between
turns still get the right author name. If no usable session/snapshot
exists, the existing "Agent" fallback applies.
The repo dependency type is widened from `repository.PlanRepository` to a
small private `planRepo` interface that adds the two session lookups —
the SQLite repository (`*sqliterepo.Repository`) already implements both,
so no caller wiring changes.
* fix(web): plan history popover row + restore button polish
- Popover content's default `gap-4` between flex children (from
@kandev/ui's PopoverContent) was rendering as visible space above the
top-most row. Override with `gap-0` so the list sits flush against the
header.
- Switch row layout from `items-start` to `items-center` so the
Restore button stays vertically centered against the row body even
when the body grows taller (timestamp + restored-from marker on revert
rows).
- Rename the per-row "Revert" button to "Restore" and prefix it with
IconRestore so it matches the dialog wording and the restored-from
marker icon. The data-testid stays `plan-revision-revert-button` for
e2e selector stability.
* fix(backend): plan revision review feedback + lint
- `wsGetTaskPlanRevision` now returns a 400 validation error when
`revision_id` is empty, matching `wsRevertTaskPlan`'s
`ErrRevisionIDRequired` branch (was silently mapped to 404 via the
service's lookup miss).
- `agentDisplayNameFromSnapshot` tries `name` first, then `label`, then
`agent_display_name`. The orchestrator's canonical key wins over any
stale older `label` that may still be in a session snapshot.
- Add `idx_task_plan_revisions_task_number` on
`(task_id, revision_number DESC)`. `GetLatestTaskPlanRevision` runs on
every plan write (coalesce check); the existing `(task_id, created_at)`
index doesn't help since these queries order by `revision_number`.
- Drop `Deprecated:` from `NextTaskPlanRevisionNumber`'s doc comment so
staticcheck stops flagging the existing test usage. The TOCTOU caveat
stays in the prose.
* fix(web): plan revision review feedback, prettier, e2e resilience
- `loadRevisionContent` reads `revisionContentCache` lazily through the
store API inside the callback, so its identity stays stable. Selecting
the cache map at the hook level was recreating the callback whenever
any task's content was cached, retriggering downstream content-fetch
effects.
- `task.plan.reverted` WS event becomes a no-op handler.
`task.plan.revision.created` fires for the same row first and already
upserts; the duplicate handler was double-evicting the
`revisionContentCache` entry and triggering an extra Zustand update.
- e2e: agent author assertion now uses `not.toHaveText("You")` +
`not.toBeEmpty()` instead of the literal `"Agent"` (which only
matched the legacy fallback — agent rows now resolve to the profile
display name).
- e2e: `openPlanPanel` retries the toggle a few times after a page
reload — the panel toggle can race hydration and silently no-op,
which broke the persistence test.
- Apply prettier to the files flagged by the formatting check.
* fix(plan): toast on silent revert failure + revision ownership check
- task-plan-revisions: when `onRevert` (the hook's `revertTo`) swallows
the error and returns null, the dialog used to close silently with no
feedback. Add an `else` branch that fires `toast.error("Failed to
restore plan")`.
- wsGetTaskPlanRevision: accept an optional `task_id` and reject with a
400 "Revision does not belong to task" when the loaded revision's
task doesn't match. Mirrors `wsRevertTaskPlan`'s ownership check so a
WS client can't read content for an arbitrary revision UUID outside
the tasks it already holds a reference to.
- plan-api `getPlanRevision` takes optional `taskId`; `loadRevisionContent`
threads the active task id so the check is exercised on the happy path.
* feat(backend): add session-scoped message search endpoint
Adds SearchMessages across repository/service/handler layers and a new
WebSocket action "message.search". Returns lightweight hits with a
60-char snippet around the first match. Session-scoped only: results
never leak across sessions. Uses dialect-aware LIKE/ILIKE so it works
on SQLite today and Postgres later.
* feat(web): add shared panel search bar and Ctrl+F hook
Introduces the reusable PanelSearchBar overlay and usePanelSearch hook
used by the per-panel search features. The hook listens on the window
and fires only when focus is within the panel root, preventDefaults the
browser find-in-page, and wires Esc to close. PanelRoot becomes a
forwardRef so panel components can expose their root element to the
hook. Adds SHORTCUTS.FIND_IN_PANEL plus shared highlight/flash styles.
* feat(web): add Ctrl+F search to terminal panels
Mounts the xterm addon-search on both passthrough and shell terminals,
exposing next/prev plus case-sensitivity and regex toggles. Invalid
regex surfaces an inline error without firing the search. Because xterm
consumes keystrokes before React, the Ctrl/Cmd+F intercept is added to
attachCustomKeyEventHandler so the shortcut opens the bar from inside
the terminal. Results counter comes from onDidChangeResults; decorations
clear on close.
* feat(web): add Ctrl+F search to plan panel
Adds a custom TipTap extension that builds a ProseMirror DecorationSet
over the document and exposes setPlanSearchQuery / planSearchNext /
planSearchPrev / clearPlanSearch commands. The current match gets an
extra class and scrolls into view. Match count is read from the plugin
state via transaction subscription, so edits to the document update the
counter automatically. Find-only — no replace.
* feat(web): add Ctrl+F search to session chat panel
Wires the new backend message.search action into a debounced client
hook and renders a hits dropdown under the search bar, with the query
highlighted in each snippet. Clicking a hit scrolls the message into
view and flashes it. When the target message is older than what is
currently loaded, the hook loops through loadOlder pages until the
message renders, making search work across lazy-loaded history without
needing to scroll-and-wait manually.
* fix(web): lazy-load xterm addon-search to avoid SSR crash
addon-search is published as a UMD bundle that references `self` at
module load. Statically importing it breaks the Next.js static
prerender of /. Deferring the import to an effect keeps the module out
of the SSR graph without changing runtime behaviour.
* fix(web): propagate plan editor via state so plan-search hook re-runs
The plan-search hook subscribed to editor transactions inside a
useEffect that depended on a ref object. Because ref.current changes do
not trigger effect re-runs, if the Editor instance was not yet ready
when the hook first mounted, the transaction handler never attached and
the match counter stayed at 0 / 0. Tracking the editor via state (in
addition to the ref) causes the deps to change when the Editor becomes
available, so the handler attaches and the counter updates.
* feat(web): allow overriding message list renderer via ?renderer= query
Exposes the "native" / "virtuoso" choice at runtime so E2E coverage can
exercise both paths without a redeploy or code change. Defaults to the
existing "native" strategy when no override is present.
* test(web): add Playwright coverage for panel-scoped Ctrl+F search
Adds an e2e/tests/search/ suite with five specs:
- panel-search-shared: cross-panel contract (Ctrl+F opens, autofocus,
Esc closes, close button, state reset on reopen) parametrised over
session, plan, and terminal.
- terminal-search: xterm addon-search integration — key intercept
without leaking "f" to the PTY, case + regex toggles (incl. invalid
regex error), Esc does not reach the shell, backspace adjusts count.
- plan-search: TipTap plugin — highlight count, exactly one current
match, counter, Enter / Shift+Enter wrapping, close clears
decorations, no case/regex toggles in plan bar.
- session-search: WebSocket-backed hits list, "No matches" state,
click-to-flash, cross-session isolation, close, and virtuoso renderer
coverage via the new ?renderer= override.
- panel-focus-routing: bar mounts inside the focused panel only.
Three tests capture GIFs for the PR description via prCapture when
CAPTURE_PR_ASSETS is set (one per panel). Helpers live in
e2e/helpers/panel-search.ts and e2e/helpers/seed-session-messages.ts;
SessionPage gains search-bar locators.
* fix(web): prevent plan-search update loop on spurious editor transactions
TipTap fires `transaction` on every cursor move/click. The match-info
handler allocated a fresh `{current, total}` object each time, so React
always saw new identity, re-rendered, and could cascade with downstream
effects (e.g. `rehydrateCommentMarks`) into a "Maximum update depth
exceeded" loop. Use a functional setState with equality bail-out so the
handler only schedules a render when the counter actually changes.
* fix(web): retry terminal search once xterm addon-search finishes loading
The SearchAddon is dynamic-imported and was stored in a ref. The
query→findNext effect called `addonRef.current?.findNext(...)` — a
silent no-op if the addon wasn't loaded yet — and its deps didn't
include addon readiness, so a query typed before the import resolved
was dropped forever. Track the addon via state so the search effect
re-runs when it becomes available (and re-binds cleanly if the terminal
is ever re-created). Also deduplicate match-info updates via functional
setState + equality check.
* fix(web): route Ctrl+F to the last-clicked panel when focus is ambient
The chat panel's message list has no focus-capturing child, so clicking
on a message left `document.activeElement === <body>` and the existing
`isFocusWithin` gate silently fell through to the browser's native find.
Fix with two complementary mechanisms:
- `usePanelSearch`: track the most-recently-clicked panel via a
window-level pointerdown capture listener. When focus is ambient
(body/html), that panel claims Ctrl+F. Window-level capture dodges
any descendant `stopPropagation` that would skip a container-level
listener.
- Chat panel root: tabIndex=-1 + onMouseDown that focuses the root when
the click target isn't already focusable. Normal path matches how
plan/terminal already work (TipTap/xterm capture focus on click).
* feat(web): show agent profile name and logo in session search hits
The hit list showed uppercase "AGENT"/"USER" with vivid blue/green
colors that clashed with the app's muted metadata aesthetic. Replace
with the actual author identity:
- Agent hits render the profile name (falling back to "Agent") with
the profile's <AgentLogo> inline — same mechanism session tabs use.
- User hits render "You" with a subtle `text-primary/80` tint that
echoes the user bubble's `bg-primary/30`, keeping a light color
differentiator without reintroducing loud blue/green.
Added `useSessionAgentIdentity` (plus a `useSessionAgentProfile` helper)
that reads from the store via two primitive selectors — the id, then
the profile — and composes the final object inside `useMemo`. A naive
single selector returning `{label, name}` triggers the "getSnapshot
should be cached" infinite loop in `useSyncExternalStore`.
* style: apply prettier formatting to search files
* fix(web): inline resolveStrategy in useMemo to satisfy react-hooks/use-memo
* fix(backend): escape LIKE metacharacters in message search
User query of `%` previously built LIKE pattern `%%` which matched every
message in the session; `file_name` also matched `filename`, `file name`,
etc. Escape the three LIKE metacharacters (`\`, `%`, `_`) before wrapping
the pattern, and declare `ESCAPE '\'` on the clause. Add regression tests
covering wildcard literals and the literal-percent happy path.
* fix(backend): slice search snippet in rune space to keep UTF-8 valid
`buildSnippet` indexed and sliced on byte offsets, so content containing
multi-byte characters (emoji, CJK, accented letters) could be cut
mid-rune — `encoding/json` then replaced the invalid bytes with `\ufffd`
in the websocket response. Switch to rune slicing and per-rune
case-folding via `unicode.ToLower`; this also avoids the
`strings.ToLower` byte-length-change pitfall (e.g. Turkish İ, German ß).
Add a handler test covering emoji, CJK, and large multi-byte content.
* fix(web): cancel backfill loop when user clicks a newer session hit
`setActiveHit` awaits up to 40 `loadOlder()` iterations when the target
message isn't in the DOM. If the user clicked a second hit while those
awaits were in flight, the in-progress loop kept running and eventually
scrolled to the original target, overriding the user's intent. Gate the
loop on a generation counter so only the most recent call's backfill
drives the scroll.
* fix(web): gate plan-search scroll side-effect on dispatch
TipTap invokes commands with `dispatch === undefined` during `can()`
checks to test applicability (e.g. before enabling a menu item). The
next/prev commands called `scrollToMatch` outside the `if (dispatch)`
guard, so a dry-run invocation would scroll the editor to a match the
user didn't navigate to. Move the scroll inside the dispatch block.
* fix(web): address review nits on search UX
- formatTime now checks Number.isNaN(d.getTime()) before formatting;
Invalid Date doesn't throw, so the catch branch was unreachable and
hits with a malformed created_at rendered the literal "Invalid Date".
- prefers-reduced-motion now silences the .search-flash animation
alongside the other custom keyframe animations.
- planScript escapes `title` symmetrically with `content` so callers
passing arbitrary strings don't produce malformed JSON.
* fix(web): fold description into opts to keep seedTask under param limit
`seedTask` had 6 parameters, violating the repo's 5-parameter cap and
failing CI lint. Fold `description` into the existing `opts` object and
update all callsites.
* test(web): add unit tests for useSessionSearch + remove redundant ternary
Cover the non-trivial hook logic called out in review: debounced fetch
coalescing, request-ID cancellation for superseded queries, null
sessionId short-circuit, and close() resets. Also simplify the
`matches.length ? 0 : 0` ternary flagged as a dead branch — both sides
were already 0.
* fix(web): exclude PanelRoot (tabindex=-1) from the focus short-circuit
`target.closest("[tabindex]")` was matching PanelRoot itself (which has
`tabIndex={-1}` so it can receive programmatic focus), causing the guard
to early-return and the `panelRef.focus()` call to never fire — defeating
the Ctrl+F focus-routing that this handler was added for.
Narrow the selector to `[tabindex]:not([tabindex='-1'])` so it only
short-circuits on genuinely interactive elements.
* fix(web): read isReadOnlyMode from live ref in shell-terminal key handler
`attachCustomKeyEventHandler` is called once and has no dispose hook, so
the inner handler keeps its initial closure forever. Other values
(sessionId, send, onFindInPanel) are read via `stateRef` so they stay
current, but `isReadOnlyMode` was captured by closure — if the prop ever
toggled mid-session, the Cmd+Arrow→Home/End path would continue firing
against a read-only terminal. Include it in the state ref for
consistency.
* fix(web): flatten doubly-nested seedTask opts in virtuoso spec; drop unused MODIFIER
The regex-based transform in 7152b936 over-nested one call in
session-search.spec.ts — `opts.description` received an object rather
than a string, so the virtuoso renderer test never received a proper
task description. Flatten it.
Also remove MODIFIER imports/declarations in terminal-search.spec.ts and
panel-search-shared.spec.ts that were left dangling behind `void` suppressors.
* fix(web): abort session-search backfill loop on close/unmount
Move reset logic into `close()` so the lifecycle is explicit (and avoids
the set-state-in-effect lint path the previous reset effect triggered).
Bump the `activeHitGenRef` generation counter on both `close()` and
unmount so an in-flight `setActiveHit` backfill can no longer issue
`loadOlder()` calls for a hidden UI.
Also extract `useDebouncedSearch`, `useSetActiveHit`, and a
`focusMessageElement` helper to keep `useSessionSearch` under the
100-line function cap.
* perf(web): skip PanelSearchBar debounce for session search
Session search already debounces the WS call inside `useDebouncedSearch`
(180ms), but the shared bar adds its own 150ms debounce on top — giving
a 330ms keystroke→request latency instead of the intended ~180ms.
Pass `debounceMs={0}` so the bar forwards queries immediately and the
hook-level debounce is the single source of timing truth.
* fix(web): replace mermaid bomb-icon error flood with toast notifications
mermaid.render() called without a container leaves orphaned error
elements (with bomb icons) in document.body on parse failures. Clean up
these orphans after every render and show an error toast instead.
* fix(web): address PR review — prevent toast flooding, include error detail, add hook tests
- Add latestRenderId guard in TipTap MermaidNodeView to skip stale
renders, preventing toast spam on every keystroke
- Include mermaid error message in toast description via CustomEvent detail
- Add useMermaidErrorToast hook tests (event listener + cleanup)
* style(web): format mermaid-error-toast test with prettier
* fix(web): include error message in MermaidBlock toast description
