* feat: add message-level conversation fork and rewind
Expose native Codex/Grok/Claude history controls through hub REST+RPC and web ConfirmDialog actions, without file rewind or composed forks. Also reconcile the duplicate hub V14→V15 migration so typecheck can pass.

* fix: hydrate fork transcript and consume Claude --fork-session
Forked HAPI children now copy the source transcript prefix so navigation is not a blank thread, and Claude drops --fork-session after the first launch so relaunches do not branch again.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: harden fork/rewind concurrency and durable history points
Skip pending scheduled rows when hydrating fork transcripts, serialize fork/rewind per session, and persist conversation history points/indexes across existing-session bootstrap and Grok relaunches.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: close remaining fork/rewind races and UI anchoring
Block sends and scheduled maturation while history actions run, order fork prefixes by invocation time, inherit history locators into children, and only offer Fork current on the live tail boundary.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: address remaining fork/rewind bot findings
Materialize Claude --fork-session before the first child prompt, validate
HAPI history boundaries before native RPC, expose forkCurrent on a latest
user boundary, fully demote unsupported conversationHistory capabilities,
and fix the truncate test setup order.

* fix: align fork-current ids and Claude fork bootstrap
Compare the latest fork boundary in assistant-ui threadMessageId space,
spawn Claude forks with the persisted session mode, and preserve
forkedFrom across existing-session bootstrap.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: close fork/rewind consistency holes at the contract layer
Hold the source history lock until Claude child binds a distinct native
id, persist Codex localId→turnId locators, and mark/block diverged
sessions when native rewind outruns HAPI truncate.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: use Codex stable lastTurnId for historical fork
Map HAPI's exclusive boundary to the previous turn's inclusive
lastTurnId so native fork context matches the hydrated transcript.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: require exact Grok native resume for fork children
Reject newSession fallback when forkedFrom is set, and keep the hub
history lock until the child binds the forked grokSessionId.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: kill active fork children before failed-fork cleanup
Bind/readiness failures can leave the child process running; deleteSession
rejects active rows, so terminate first then remove the HAPI session.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: close remaining fork lock, hydrate, and todos gaps
Reject mode switches during history actions, batch-copy fork
transcripts in one SQLite transaction, and rebuild todos after
fork hydrate / rewind truncate.

* fix: allow Codex historical fork before the first turn
Use experimental beforeTurnId when there is no previous turn for the
stable inclusive lastTurnId boundary.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix: mark Grok history busy immediately after dequeue
Hub idle checks clear once messages-consumed fires; hold the busy flag
across permission sync and rewind-points lookup before prompt starts.

Remote sessions get an authoritative context_window injected into usage by
the CLI (from SDK result modelUsage), but local-mode sessions forward raw
transcript JSONL whose usage has no context_window, so the web fell back to
getContextBudgetTokens — which could not tell Fable's 1M window from its
bare id (only the "[1m]" suffix was recognized) and received session.model,
which is usually null for local sessions, defaulting to a 200k budget. A 1M
Fable session with ~256k of context showed 135% used with an over-limit
warning instead of ~26%.
- modelConfig: recognize Fable ids (fable, fable[1m], claude-fable-*) as 1M
- reducer: LatestUsage carries the usage-bearing message's own model
- StatusBar: new contextModel prop feeds the fallback heuristic only;
the model prop's other semantics are unchanged
- HappyComposer forwards it; SessionChat passes
latestUsage.model ?? session.model
EventSource reports an error the moment a connection drops, including
while it is already retrying by itself - readyState is still CONNECTING
and the stream is typically back within a few seconds. useSSE forwards
that straight to onDisconnect, and App turned it into a full-width
"reconnecting" banner synchronously, so a blip the browser recovered from
on its own still read as a broken network.
Route the disconnect through a small hook that waits out a grace period
first. Genuine outages still surface the banner, just a moment later;
recoveries that beat the timer stay silent. The sibling syncing banner
already debounces this way in useSyncingState.
The grace period is anchored to the first drop, so repeated failed
retries cannot push the banner back indefinitely.
Replace the always-visible wrapping chip row below the md breakpoint with a
filter icon button in the session list header (right side, next to the new
session button). The button opens a radio menu with per-machine counts and
an inline health summary, shows an active-filter dot, clamps to the
remaining viewport/safe-area space, and supports Escape/Arrow-key
navigation with focus restore. Desktop keeps the one-tap chip bar.
Remove the refresh icon button from the session list toolbar and make
the list itself the refresh affordance via a touch pull gesture.
Gesture (SessionList):
- Touch listeners on the scrollable list container; pull engages only
at scrollTop 0, with 16px feedback / 64px trigger thresholds, and
fires on release past the trigger. Mirrors the established
pull-to-load-older pattern in HappyThread.
- Touch-only by design: desktop has no overscroll bounce, so a wheel
pull feels broken; desktop keeps relying on SSE live updates and
query focus refetch.
- onRefresh widened to () => Promise<unknown> | void so the indicator
tracks the in-flight refetch and ignores re-entrant pulls.
Feedback:
- Status pill over the list (role=status, aria-live) shows
pull/release/refreshing states with a spinner while refreshing; it
also covers the initial useSessions load (isLoading), which lost its
only busy indication when the toolbar button was removed.
- The success toast is dropped (the pill is the feedback); the failure
toast is kept. handleRefresh now returns its promise.
Empty states (review P2s):
- SessionsEmptyState and the no-results message move from the shrink-0
header container into the scroll container, so the gesture works on
the visible empty state (retry path after a failed initial fetch)
and short viewports scroll instead of crushing the gesture area.
- SessionsEmptyState is gated on !isLoading so a slow initial request
no longer flashes the final empty state with active actions.
i18n: add sessions.refresh.pull/release/refreshing (en + zh-CN),
remove now-unused button.refresh and sessions.refresh.success.*.
Desktop wheel pull was implemented and then reverted after review.
* refactor(web): pin abort button to end of composer left cluster
Abort's position shifted with conditional siblings (terminal/switch/
schedule), making the destructive action's location unpredictable.
Move it to the last child of the left button group so it's always
immediately left of Send — pure JSX reorder, no markup/props/handler
changes.
* fix(web): keep abort last in default toolbar
Keep the product default predictable without changing saved custom order or the registry used to append missing items.
* fix(web): show Auto instead of Default for Cursor model picker
Cursor CLI uses `auto` for automatic model selection; labeling it
"Default" in HAPI was confusing and inconsistent with `agent --list-models`.

Move the session-list search out of its dedicated full-width row and
into the sidebar toolbar, so the sidebar gets one compact header row
instead of two stacked rows.
Behavior:
- Collapsed by default: a search icon sits at the left of the toolbar
row, on the same line as the existing tool icons (codex import,
refresh, browse, settings, new session).
- Clicking the icon expands the input to fill the entire row width
(tool icons hide) and focuses the input; when focus leaves the
search container the input collapses back to the icon.
- Query and date range stay applied while collapsed; the icon shows
an indicator dot whenever any filter is active.
- The date-range picker stays inside the expanded input.
Implementation:
- SessionList gains a headerActions prop and renders a single header
row: [collapsible search] [spacer] [optional renderHeader plus]
[headerActions].
- SessionsPage drops its own toolbar wrapper and passes its five
buttons through headerActions instead.
- The safe-area top inset moves to the router container wrapping both
the error banner and the list, so iOS PWA error text no longer sits
beneath the status bar/notch.
Focus handling (review follow-ups):
- Controls that unmount themselves on click (clear-query X, picker
backdrop, range-end selection, picker footer Clear) silently moved
focus to <body>, leaving the search expanded but no longer
collapsible via blur. Each now returns focus to the input; the
picker footer Clear is wired through a dedicated onClear prop.
- Header actions can no longer be suppressed by a stale expanded
state: they render whenever the search control itself is absent
(e.g. the session list empties via SSE), and the expansion resets
when the list becomes empty.
i18n: add sessions.search.open (en / zh-CN).
Tests: adapt existing search/date-filter tests to expand the search
before interacting; add regressions for collapse-on-blur query
persistence, focus restore after clearing the query and after
clearing the date range, and header actions surviving an emptied
session list.
* feat(web): feature-flagged rich composer for inline session @ mentions
Custom segmented contenteditable (not TipTap) inserts caret-local session
atoms from the existing @ picker and serializes to markdown links on send.
Textarea path remains default until flag parity dogfood.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(web): rich composer mention boundary + #1215 refs
Treat U+FFFC mirror atoms as word boundaries so @ after a session
token still opens autocomplete. Point comments at Fixes#1215.

* test(web): peer-stack e2e for rich composer session @ mentions (#1215)
Smoke: flag on, @ picker inserts inline session atom chip (not prose dump).
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(web): preserve newlines in rich composer Enter-newline mode
Chromium splits contenteditable on Enter into block divs; serialize those
as \\n and insert <br> when parent leaves Enter unhandled (Shift+Enter /
enter-inserts-newline).
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(web): show @ badge when rich composer mentions flag is on
Dogfood was invisible: flag-off looks like a normal textarea, and flag-on
had no chrome. Surface a small @ badge when enabled.
* fix(web): rich session composer on by default (not a user setting)
The plan dual-path was an engineering kill-switch, not an opt-in. Default
to the segmented composer; only richMentions=0 disables. Drop the flag
badge and record a peer-stack motion proof covering chips + baseline UX.
* fix(web): make rich composer Shift+Enter create a visible newline
Trailing <br>+empty text node was a silent no-op at EOL. Use
insertLineBreak (ZWSP pad fallback), assert real \\n in peer e2e.
* feat(web): hover tooltips on rich composer session chips
Show full title, status, short id, and path on chip hover via a portal
bubble fed by live useSessions lookup (drafts fall back to title + id).
* fix(web): dismiss rich composer chip tooltips on mouse leave
contenteditable pointerout/relatedTarget was flaky so tips stuck after

insertNode always leaves an empty text sibling, so !nextSibling never

* fix(web): drop custom onDrop from rich composer
Intercepting drop without caretRangeFromPoint landed text at EOF or
no-oped in-editor moves. Native CE drop is enough for #1215; paste

* feat(web): sidebar-parity tooltips on rich composer session chips
Reuse SessionRowSummary (flavor, thinking/attention, schedule, todos,

* chore: keep peer-stack e2e off the upstreamable tip
Peer specs and playwright.peer.config stay on fork main per
docs/tooling/peer-stack.md; default config still testIgnore's e2e/peer.

* feat: cite sessions with UUID wire + inspect_peer for agent/overseer
Rich composer chips already serialize to [title](/sessions/<id>); flush
before send so the agent prompt never gets title-only chip text. Add
inspect_peer (MCP + hapi inspect-peer) as the read twin of ping_peer so
that same id is immediately usable for overseer/agent peer lookup, with
system-prompt glue from citations to inspect/ping.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(cli): gate inspect_peer behind permission approval
Cross-session history reads need the same prompt path as ping_peer:
keep inspect_peer off Claude --allowedTools and treat it as sensitive
in ACP/OpenCode read-only mode so prompt injection cannot silently
enumerate peer transcripts.

Remove the top-right Loading messages pill shown while tail reconciliation runs with cached conversation content.
Keep background tail synchronization silent so it does not compete with older-history loading feedback or imply that the visible conversation is blocked. Cold-start skeletons, pull-to-load guidance, older-page loading state, unseen-message navigation, and global reconnect feedback remain unchanged.
