`getRuntimeKey` keys caches, stores, and persisted state across the whole UI,
so it runs on store reads, event handling, and render paths. Until the runtime
endpoint is explicitly initialised, every call re-derived the key by trimming
two injected globals and constructing three URL objects.
In a streaming capture this made `readInjectedLocalOrigin` the single most
expensive application function: 315 ms of self time, 12% of all main-thread
busy time. After the change it does not appear in the profile at all, and the
same capture went from two long tasks to none, with the longest task dropping
from 210 ms to 47 ms.
The key depends only on the active API base URL and two injected globals, and
`switchRuntimeEndpoint` writes the injected API base URL at runtime, so the
cache is validated against the raw untrimmed values rather than memoised
outright. That comparison allocates nothing and still recomputes as soon as any
input changes. Tests cover both directions, including an operation-count
assertion that repeated calls construct no URLs.
The streaming profiler also reports output-normalised metrics, because response
length varies between runs and makes per-second totals incomparable.
Adds `bun run profile:session`: creates a session, opens it in a real
browser, dispatches a prompt through the supported `openchamber session` CLI,
and records until the session reports itself idle. No input is synthesised, so
everything captured is the app reacting to its own event stream.
Streaming is judged by responsiveness rather than totals, so the report leads
with the long-task distribution, style recalculation and layout rates, frame
production, and the application's own stream counters.
Two failure modes are detected rather than reported as clean results. A session
belonging to a directory the browser is not viewing renders nothing and
produces a perfectly quiet profile, so the run verifies both new message
elements in the DOM and message-list render counters. And `RunTask` is only
emitted under the disabled-by-default timeline category, so a capture without
it reports zero long tasks; the missing-task case is now called out instead of
being shown as zero.
Metric helpers are shared with the idle profiler.
Idle cost depends on which surfaces are mounted, so the profiler needs to
reach those states without a human driving the UI.
`--panel <mode>` opens the context panel by seeding the persisted store the
app reads on boot, using the same tab identity rules as `useUIStore`.
`--then-tab <name>` navigates through the router after settling, which leaves
already-mounted surfaces mounted and measures what a screen keeps doing once
the user has moved on. Both drive real application state instead of
synthesising clicks, so the recorded window stays free of input-driven work.
Adds `bun run profile:idle`: a fully unattended capture of what OpenChamber
does while nobody interacts with it. It reports main-thread busy time, style
recalculation and layout rates, DOM node and listener growth, heap trajectory,
a CPU sampling profile, and per-call-site attribution of timer, animation
frame, and observer work.
Chrome throttles timers and stops producing frames for occluded or backgrounded
windows, which silently reports an idle-looking renderer regardless of what the
page schedules. Launch flags now disable that throttling, and every run measures
frame liveness so a throttled capture is reported as a warning rather than as a
clean result.
CDP launch and client code is shared with the existing browser profiler.
German was added to the interface but not to the walkthrough's own language
list, and nothing failed: the picker offered Deutsch because it is built from
the interface locales, the server resolved the tag to English, and a German
reader paid for a walkthrough written in English while the picker still said
Deutsch.
The two lists cannot be one — the server cannot import from packages/ui — so
a test reads i18n/runtime.ts and compares them, in both directions and through
normalizeLanguage. Drift this quiet needs a test rather than vigilance.
Session directory resolution had no precedence contract: the selection-time
directory short-circuited every lookup, and a persisted runtime value was
consulted before the authoritative record. A worktree session selected before
its directory store bootstrapped kept the active-directory fallback, and that
guess was persisted, so it survived reloads and restarts.
Directory resolution now lives in one module and orders sources by whether the
server confirmed the path, not by whether the value is local or synced:
authoritative (the child store that holds the session) > server-confirmed
selection > worktree attachment/metadata (the requested path, pre-canonical) >
remembered. A guessed selection is no longer persisted, remembered, or ranked.
Chips read the same resolution the composer used, so queue keys cannot diverge.
Queued auto-send could strand an item indefinitely: backoff, missing send
configuration, and the recent-abort window all returned without scheduling a
wake-up, so the queue only retried when an unrelated status or directory change
re-ran the effect. A retry scheduler now wakes it at the earliest known time.
A rejected send rolls the optimistic message back while the composer stays
silent for transport failures, which makes it indistinguishable from nothing
happening. Failures are now recorded to a bounded in-memory log surfaced in the
About diagnostics report, alongside a directory-resolution breakdown, plus
__opencodeDebug.diagnoseSessionDirectory() and getRecentSendFailures().
Prompted by a report of worktree prompting silently failing. That failure was
not reproduced locally, so the diagnostics are what will identify it.
A guided explanation is only useful in a language the reader reads, so the
panel header gets a language picker alongside the model one, defaulting to
the interface language. Like the model, it is request state rather than a
setting: the language travels with the read and the generation, and the one
a walkthrough was written in is stored with it, so reopening a review
describes what is there instead of what a fresh one would be.
Only prose is translated. Hunk aliases resolve back to hunk ids and
icon/importance are validated against fixed English values, so a translated
one would be dropped by the normalizer — silently losing an anchor or a
style. Identifiers and paths stay as they appear in the code.
The language is part of the cache key, and a read now asks the cache for the
exact request it was given before falling back to the pointer. Without that
the panel answered a request to switch languages with the text it already
had, leaving the other language unused in the cache.
Alongside it:
- The answer budget is derived from the resolved model instead of a flat 24k.
That number was the same for a 64k-context model and for one that admits to
384k output tokens, and on the latter it was the only reason generation
failed: the model spent the whole allowance reasoning and returned nothing.
It is now min(96k, max(24k, a quarter of the context)) capped by the
catalog's output limit, decided once so the input reserve and the request
cannot drift apart.
- A read no longer offers Cancel. It is a few hundred milliseconds of git with
nothing to cancel, and the button flickered on every model or language
change. When the panel is showing a fallback, a banner names what is on
screen versus what was asked for — only once the read has settled.
- The header keeps one 32px control height and drops its labels below 680px
instead of squeezing them to two letters and an ellipsis.
Docs and module documentation updated in every locale.
Use the real status-warning tokens (--status-warning-bg did not exist, so
the card rendered without a fill), drop the decorative icons, and fold the
conflict count into the title as a single full-message key per locale.
The operation description now wraps instead of truncating, and both the
conflict and ready-to-continue states share the same action layout.
The tablet ran the phone layout with a half-finished iPad draft on top: two
custom sidebars, a leftover overflow menu, split Files/Changes header buttons,
and phone-width sheets stretched across a 13" screen. This brings it onto the
phone's navigation model and keeps only the differences a large screen earns.
- Sessions are a persistent resizable left sidebar; the overflow menu is gone
and its destinations moved into that sidebar's footer (connected instance,
settings, pending web update) and into the workspace drawer.
- The workspace (Changes / Files / Terminal / Notes / MCP) is the phone's
drawer everywhere: a resizable right sidebar where the screen can host one
(up to 900px) and the full-cover drawer otherwise, with its mounted panes —
an open diff, an edited file, an attached terminal — surviving rotation.
- Header dropdowns are anchored popovers: the recents switcher mirrors the
usage overlay on the left, and its trigger is sized to the title rather than
to the free width.
- App-level pages (settings, instances, update, an opened plan) render as
centered dialogs instead of covering the screen.
- Overlays center on the chat column through published insets, so the model
and directory pickers no longer sit off-centre; the directory picker also
stops overriding the shared width clamp.
- Wide chat layout applies to mobile surfaces, where a tablet chat column is
finally wide enough for the setting to mean anything.
The layout gate is a live size class rather than a device check, so Android
tablets and foldables are covered by the same code:
- `enabled` when the shortest viewport side is at le
sw600dp). The short side is what makes this a size question instead of a
device question — a phone reports ~360-430 whichev

ones do not, exactly as the previous orientation check did.
Hardware keyboards are read natively. iOS reports them through GCKeyboard,
published to the web layer at document start and kep
disconnect and foregrounding; the layer stops inferring once that answers. A
single early publish was not enough — the connect no
already-attached keyboard fires before the page exists, and GameController can
populate late — so the state is re-published across
resume. With a keyboard attached the draft screen keeps its starter chips and
the composer never collapses; tablets skip the colla

now-unreachable overflow menu, fullscreen terminal/MCP/notes surfaces and their
locale key are deleted.
Device behaviour is unverified — the tablet layout,
keyboard bridge and the foldable size class have not been exercised on
hardware, and the 600/1000 thresholds are derived fr
rather than measured on a foldable.
A diff is ordered by file path, which is almost never the order in which a
change makes sense. This adds a Walkthrough surface that reorders it: the model
groups related hunks into stops, explains what each group changes about
behavior, and orders the stops so each builds on the last. It explains and
orders; judging code stays with the existing Review action.
Reviews uncommitted work (all, staged, unstaged), a branch against its base, or
a pull request. Generation is always user-initiated — nothing runs on a timer,
on a file change, or as a side effect of opening a panel.
Invariants worth preserving:
- Hunk identity is derived on the server and only there. Ids are content
hashes, so an anchor that no longer resolves is proof the code it described
changed, and staleness needs no heuristics. The client matches ids to ids and
never recomputes them; two implementations would have to agree forever.
- The digest is never truncated. A diff that does not fit the model's context
is refused with an actionable reason, because a walkthrough written against
half a diff reads as confident and is wrong.
- Nothing disappears. Lockfiles and other generated output are excluded from
the model's input by name — never by size — and everything no stop covers is
listed at the end, so "have I seen all of it" stays answerable.
- Cost is explicit. Results are content-addressed, so returning the working
tree to an earlier state costs nothing; generation outlives its request, so a
refresh detaches the client rather than discarding paid-for work, and only an
explicit cancel stops it.
Supporting changes to shared modules:
- git: expose the existing getRangeDiff as GET /api/git
listUntrackedPaths and getUntrackedDiffs. The latter resolve the repository
once for a batch instead of per file, taking a panel
~340ms on an 80-file working tree.
- small-model: structured output across four wire forma
and abort signal, and an onOverflow policy so an oversized prompt fails
loudly instead of being silently clipped. A provider
remembered so the prompt-side fallback goes first next time.
- models.dev metadata: surface structured_output as tri
false blocks a model, a missing field does not, because the catalog omits it
for roughly half of all models.
Desktop and tablet only: VS Code serves Git through its
these routes, and the mobile shell does not consume the surface registry.
Docs: packages/docs walkthrough page in English and all eight locales.
Navigation model rebuilt around two full-width drawers and a minimal
header (sessions / title-switcher / usage ring / workspace):
- Left sessions drawer: cross-project tree with live status indicators,
swipe actions on sessions (rename/archive/delete) and on group headers
(project edit / two-step close, worktree delete), reorder-only edit
mode with collapsible project cards and draggable worktrees, app-level
footer (connected instance, settings, pending web update).
- Right workspace drawer: Changes / Files / Terminal / Notes / MCP as
pill tabs (inactive tabs icon-only); panes stay mounted once visited.
The full desktop file editor serves the Files tab; read/skill tool taps
in chat open the file there at the requested line.
- Header session switcher on title tap: 10 cross-project recents with
live busy/attention indicators and project · branch metadata; the
usage ring opens a metadata overlay with an explicit loading state.
- The overflow menu is gone on phones (its destinations moved into the
drawers); iPad keeps it until its dedicated layout pass.
Correctness and continuity:
- /auth/session answers bearer-first, so a stale WebView cookie can no
longer mask a revoked device token; cold launches classify failures
fast and land on an explicit connect screen.
- Authoritative session snapshots raise frozen ordering baselines and
stale live ranks — recents stay truthful after the app slept.
- Cold launches reopen the last active session per instance (persisted
pointer, confirmed against a sessions snapshot; a user-opened draft
clears it), with a logo hold instead of a draft flash.
Also: collapsed pill composer gains the stop control; chat tool rows
share one 36px rhythm; Task subtool rows truncate; larger bottom safe
area so the composer clears big-screen corner radii; Capacitor build
hides About/Update (store updates apply there); widgets link to the
sessions drawer with a list icon; MobileApp split into focused modules;
five mobile-surface detectors unified; translucent borders normalized to
70%; all new strings translated across the 10 locales.
iPad and foldable layouts are intentionally untouched - separate next version PR.
Untracked symlinks now show as link entries in diff output.
File diffs display symlink targets instead of following them.
Added tests for patch and split diff behavior.
Route live VS Code permission requests directly to directory-scoped permission replies instead of blocking on the refresh-only state preflight.
When auto-accept is enabled after prompts are already visible, reply to the authoritative local requests first, then reconcile and deduplicate the server pending list. Keep state verification for reconnect and refresh flows so stale resolved requests are not resurrected.
Add regression coverage for live events, existing prompts, directory routing, retry behavior, stale reconciliation, and network failures.

Require Markdown exports to load every available message page before formatting the conversation. Abort incomplete root exports, retain explicit child-session skip warnings, and guard complete-history pagination against failures and cursor cycles.
The VS Code bridge re-mapped the already-mapped platform value from the
webview, collapsing every install to platform "web"; it also sent the
installId even when usage reporting was disabled. The remote-instance
update poll in the header and the post-update wait poll now send
reportUsage=false so status checks no longer count as activity.
- Drive the sticky-fade identity overlay's visibility synchronously from the scroller's top-scroll attribute (CSS :has), and seed its leading project synchronously, so it appears in the same frame the mask hides the real header instead of a React commit later (removes the one-frame blink)
- Match the overlay's vertical box to the real header rows (py-1 instead of a centered h-7) so the identity does not shift a few pixels on the sticky handoff
- Add OpenChamber brand theme (dark+light): Vitesse syntax over OpenCode-deep neutrals with Flexoki accents, harmonized in OKLCH
- Add scripts/harmonize-theme.mjs: align accent saturation/lightness and boost syntax chroma via OKLCH
- Set default theme to OpenChamber (was Flexoki)
- Rename fields-of-the-shire off the openchamber-* id; keep it as a normal preset
- Remove OpenCode and OC-2 ports and all disabled theme JSON definitions
- Make panel/header/sidebar borders opaque and theme-driven; global default border now uses --border instead of hardcoded rgba
Track each native mobile password-unlock operation with a monotonic generation. Cancelling the password prompt immediately invalidates the active operation and releases the busy state.\n\nEvery asynchronous login boundary now verifies that its operation is still current before reporting errors, writing a client token, persisting connection metadata, switching the active runtime, or notifying the connected surface. A stale relay login still closes its unadopted tunnel, while its finally block cannot clear the busy state of a newer password attempt.\n\nAdd a focused regression test that models a deferred password completion after cancellation and verifies it cannot apply the runtime-switch side effect.
