Two mitigations for local multi-instance contention over the shared relay
identity:
- A standby instance now waits a 2-minute grace period after the host claim
frees before taking over, so a cleanly restarting host (app update or
relaunch) — which reclaims at boot with no wait — always wins the restart
window instead of stranding paired devices on another process.
- Dev instances never host the relay passively: dev scripts set
OPENCHAMBER_RELAY_HOST=off and the Electron dev shell is detected via
OPENCHAMBER_ELECTRON_DEV. Explicit enable/pairing on such an instance still
force-claims; OPENCHAMBER_RELAY_HOST=on overrides.
* fix(ui): open app deep links from chat after confirmation
DOMPurify's default URI policy stripped href from anchors with custom
application schemes (obsidian://, vscode://, ...), so every app link
rendered in chat was dead across web, desktop, VS Code, and mobile.
- Classify safe app-link schemes in lib/url.ts (browser-handled,
scriptable, webview-internal, network, and self-deep-link schemes
stay excluded) and let openExternalUrl accept them
- Keep app-link hrefs through the markdown sanitize hook
- Intercept app-link clicks in the markdown renderer and route them
through a confirmation dialog (Trust and open / Open once, dismiss
to cancel) mounted in the desktop/web app root and the mobile shell
- Persist per-device trusted schemes in a zustand store; trusted
schemes open without asking again
* feat(settings): manage trusted app link schemes in General
Add an App links section to Settings > General listing the application
schemes trusted on this device with a delete action; removing a scheme
restores the confirmation dialog for it. Register the section in
settings search.
* fix(ui): enforce app link confirmation
* fix(ui): handle app links by runtime
* fix(vscode): keep app links unsupported
* fix(settings): clarify trusted app links

A project could pin the model new chats start on, but not the level to
run it at: the default cascade dropped any variant as soon as a project
model won, and only ever considered the global one — which belongs to
the global model.
Projects now carry `defaultVariant` alongside `defaultModel`, stored and
sanitized only next to that model, and the cascade passes it through.
Both controls sit in one "Defaults for new chats" group laid out like the
Sessions defaults, and the level appears only for models that offer them.
Changing the default model, variant or agent wrote the chat's live
selection unconditionally. For a session carrying its own choice the
effect was mostly transient — ModelControls restores that choice on the
next hydration — but a message sent right after the change went out on
the new model.
The guard is the same pair of signals ModelControls restores from
(shouldPreserveManualModelOverride): a manual selection plus a saved
selection for the current session. Chats following the default still
switch immediately.
Picking a project in Settings called setActiveProject, which relocates
the chat, the session list, the file tree and the Git surface. Reading
another project's MCP servers or agents moved the user's whole app.
It had to, because the configuration stores resolved the directory
themselves from the active project and held one flat list. Each of them
now takes an explicit directory — omitted still means the active project,
so every caller outside Settings is unchanged — and keys loaded data by
directory next to a flat mirror of the active project. Chat, autocompletes
and pickers keep reading that mirror; a load for another directory writes
only the map. A failed load restores that directory's previous list.
Settings resolves its own directory through useSettingsDirectory, backed
by a session-local settingsProjectPath that follows the active project
until the user picks something else.
Adding an SSH connection now starts from the hosts in the SSH config
instead of a blank command field, ports and install options sit behind
Advanced settings, and each connection reports one of three states with
the failure text and an action that resolves it.
Remote installs no longer touch the root-owned global npm prefix: npm is
pinned to a prefix under $HOME and bun is resolved at its known location,
because an SSH login shell exposes neither on PATH. The opencode CLI is
resolved the same way and handed to the remote server through
OPENCODE_BINARY, and the server is started and stopped through the
resolved binary rather than PATH — the HTTP shutdown route sits behind UI
authentication and never stopped anything.
A managed remote server can also be published to the remote machine's own
network. That requires a UI password, enforced in the form and again in
the SSH manager.
Plain Enter now inserts a newline in the expanded composer
Cmd/Ctrl+Enter still sends the message
Helps avoid accidental sends while writing long prompts
Commit generation now samples the last 10 commit subjects and instructs the
model to match their language, prefix convention, and length, falling back to
Conventional Commits only when the history shows no consistent style.
PR generation probes the conventional pull request template locations and
reuses the repository's own sections and checklists as the body structure when
one is found.

Parakeet is an offline model trained on whole utterances, so re-decoding
the growing buffer to animate a live transcript cost O(n^2) work for a
result the final decode replaced. Sessions now decode once per committed
segment, and the composer shows a scrolling waveform of the mic level
instead of running text.
Long dictations split at a pause once past 60s (hard cap 90s) instead of
on a blind 15s timer, so cuts no longer land mid-word. Committed segments
decode while the user is still speaking: a 185s dictation returns 4.1s
after stop instead of 11.0s, with identical text (816 vs 817 words).
Also fixes two ways the stream manager could silently drop transcribed
audio. It now counts the commits it issued instead of trusting the
session's echoed events, so a commit still in flight when the client
finishes can no longer be left out of the final text. And segment
byte/peak accounting is reset where the commit is issued rather than when
the event arrives, which could mistake the tail of a dictation for
silence and clear it.
* fix: reconcile busy sessions after managed OpenCode restart
Forced health-check restarts previously rebound the event stream without
settling in-flight turns, so sessions stayed busy with no terminal state.
Interrupt those sessions, classify health failures, and retain bounded
process diagnostics for post-restart diagnosis.

The panel stored notes, todos and plans inside one shared JSON file that
six unrelated domains also wrote to, synchronised itself through window
CustomEvents, and could only read plans. It is now Project knowledge:
server-owned storage with explicit routes, a store with rollback, a
section sidebar, plans that open and edit in place, and search across
all of it.
Notes and plans the user pins travel with every message sent in that
project. Pinning is project state, not an attachment to one message, so
it holds until unpinned and the work status panel names what is riding
along and can detach it.
Agent memory is added alongside, in two scopes: what is true about the
user, and what is true about this codebase. The split is not cosmetic —
a wrong project fact costs one project and is noticed, while a wrong
global fact quietly shapes every session everywhere and the user has no
code to check it against. It stays separate from notes so an agent
mistake cannot land in what the user wrote. Sessions receive an index of
titles only; bodies are read on demand, because an index carrying full
text grows until it crowds out the conversation.
Deciding what a session must be told, and whether it has been told, now
lives on the server. The client owned it before, which meant sessions
started without a UI — scheduled tasks, sessions the agent dispatches —
received nothing at all, and a tab's record of what it had sent outlived
the conversation: after compaction the agent no longer held the block
while the tab went on believing it did. What was delivered is recorded
in the session's own metadata, and compaction restores it through the
runtime that already restores pinned messages, in the same turn.
Agent memory ships dark behind OPENCHAMBER_MEMORY_ENABLE: unset, there
is no tool, no routes, no session index, no settings row and no panel
tab. Absent rather than switched off, so nothing invites turning on a
feature that has not been announced. Pinned notes and plans are
unaffected and ship as normal.
* fix(proxy): reuse upstream connections for OpenCode API requests
`createProxyMiddleware` was constructed without an `agent`, so `http-proxy`
fell back to `agent: false`. That disables connection pooling and forces
`Connection: close` on every proxied request, consuming one ephemeral port
per request.
Measured against a real `opencode serve` instance, 200 sequential requests
through the proxy created 201 TIME_WAIT entries (1.005 ports/request). With
a keep-alive agent the same load creates 0.
On macOS the ephemeral range is 16,384 ports and TIME_WAIT lasts 30s, so
sustained traffic around 546 req/sec exhausts the pool — after which every
process on the host fails to open outbound connections with EADDRNOTAVAIL.
`maxSockets: Infinity` preserves the unbounded concurrency of `agent: false`,
so this changes connection reuse only, not request throughput.
Partially addresses #2915.
* fix(proxy): derive proxy agent class from the target scheme
Addresses review feedback on #2916. The first commit created an
unconditional `http.Agent`, which regresses external OpenCode servers
configured over https via `OPENCODE_HOST` (accepted by env-config.js).
http-proxy dispatches through `https.request` when the target protocol is
`https:` (http-proxy/lib/http-proxy/passes/web-incoming.js:126), and
`http.Agent#createConnection` is plain `net.createConnection` — so an
http.Agent would open a plaintext socket to a TLS port and fail every
proxied request. `agent: false` previously worked for both schemes.
`createOpenCodeProxyAgent(target)` now returns an `https.Agent` for https
targets and an `http.Agent` otherwise, derived once from
`resolveProxyTarget()` at registration so the single shared instance is
preserved across `apiProxy` and `interactiveOAuthProxy`.
Guarded in both test layers, verified to fail when the selection is
reverted to an unconditional http.Agent. `https.Agent` extends
`http.Agent`, so the http cases assert `not.toBeInstanceOf(https.Agent)`.
* Round 2: fix: resolve the proxy agent lazily so cold starts honor https
Addresses the round-2 blocker on #2916. Deriving the agent class at
registration is too early: startup-pipeline-runtime.js calls setupProxy()
(line 104) before bootstrapOpenCodeAtStartup() (line 141), so on a fresh
process state.openCodePort is null, buildOpenCodeUrl() throws
(network-runtime.js:86-88), and resolveProxyTarget() returns the http
loopback fallback. An external server configured via OPENCODE_HOST=https://
only appears on state.openCodeBaseUrl after bootstrap, so it was still
getting a plain http.Agent — the regression the previous commit intended
to fix.
`agent` is now a getter backed by a per-scheme memoizing resolver.
http-proxy-middleware rebuilds per-request options with
`Object.assign({}, this.proxyOptions)` in prepareProxyRequest, which invokes
getters, so resolution happens at request time while still yielding one
shared pool per scheme.
Tests now model the production ordering — registration while the port is
null and buildOpenCodeUrl throws, then an https base URL appearing after
bootstrap — and fail against the eager implementation. A behavioral test
pins the http-proxy-middleware option re-read the fix depends on, so a
library change that froze options would fail loudly instead of silently
regressing https targets.
The resolver is module-private; `bun run dead-code` flagged it as an
unused export when it was exported.
* Round 3: docs(changelog): note upstream connection reuse under [Unreleased]
Repo precedent adds [Unreleased] bullets for comparable proxy/stability
fixes (1.18.4 Stability, 1.9.3 Reliability/Proxy). Non-blocker raised in
review on #2916.
* Round 3: docs(changelog): use repo-standard 'behavior' spelling
* Round 4: docs(changelog): don't imply a restart is the only recovery
The ephemeral port pool drains on its own once the exhausting traffic
stops (TIME_WAIT expiry), so a restart is sufficient but not necessary.
Optional nit raised in review on #2916.
* Round 5: fix: construct the proxy agent through one factory; widen the pool
Review found the https branch was mutation-uncovered: the resolver
re-implemented agent construction inline instead of calling the exported
`createOpenCodeProxyAgent(target)`, so replacing its https branch with
`new https.Agent()` — dropping OPENCODE_AGENT_OPTIONS, and with it
keep-alive — left the entire suite green. Since `createOpenCodeProxyAgent`
also had no production callers, its four tests were pinning dead code.
Delegating collapses both: the factory is now the single construction
path, and the mutation fails 2 tests including the live resolver path.
Also from review:
- maxFreeSockets 32 -> 256 (Node's own default). The lower cap evicted
pooled sockets under concurrency, reintroducing the churn this agent
exists to prevent: at 64 concurrent requests it left 303 sockets in
TIME_WAIT versus 0 at 256.
- Added `timeout` to OPENCODE_AGENT_OPTIONS. Free-socket eviction is
governed by agent.options.timeout, which was unset, so idle sockets
persisted until the peer closed them. `keepAliveMsecs` is the TCP probe
delay, not the idle lifetime.
- resolveProxyTarget() now checks openCodePort before calling
buildOpenCodeUrl instead of relying on it throwing. The port is nulled
on several runtime paths (health-check failure, failed restart), so a
degraded OpenCode made every proxied request pay for a thrown-and-caught
exception — and the getter added a second call per request.
- Test fixtures use :4096 rather than :443; WHATWG URL elides the default
port, so parseInt('') is NaN and env-config rejects that host. The
fixtures modeled a state that cannot reach production.
- The getter-read assertion is now exact (0 at construction, 1, then 2)
rather than >= 2, which would have passed if the getter were read twice
at construction and never per-request.
- listen() rejects on 'error' and servers start inside try/finally, so a
bind failure fails the test instead of hanging to timeout.
Review follow-up on the #2769 highlight caches.
Fingerprint strength. The block/highlight caches are now global and
content-addressed, so a hash collision no longer mis-colors a block — it returns
a *different* block's rendered HTML and shows the user source they never wrote.
Length + one 32-bit FNV-1a is not enough key space for that failure mode at
session scale. `contentFingerprint` now combines two independent 32-bit
multiplicative hashes with a final avalanche (~64 bits); two multiplies per
character are free next to Shiki tokenization.
Streaming churn. Content addressing made every streaming step of the trailing
`live` block insert a new cache entry, so one long message evicted the settled
`full` blocks the fix exists to keep warm. `full` and `live` blocks now use
separate caches; the live cache is small (32 entries / 2MB) because it only has
to absorb repeat renders of the same step.
Redundant worker-side caches. `markdown-worker.ts` is the only sender to the
Shiki worker, and its client cache is larger than the worker-side ones, so the
worker caches could not serve a hit the client had not already served — they
only duplicated up to 48MB of payloads in a second heap. Removed; the reason
memoization belongs on the client is now documented there, along with why only
`highlightTokens` carries a theme in its key.
Dead `cacheKey` plumbing. `renderMarkdownBlocks` kept a `cacheKey` parameter it
only `void`-ed. Removed it and the now-unused `useMorphdomMarkdown` prop; the
remaining call-site local is renamed `fadeKey` for what it actually keys.
Tests: image-mode cache identity, streaming-does-not-evict-settled-blocks,
live-cache reuse, and a 20k same-length-source fingerprint collision check.
Each new guard was verified to fail without its fix.
The token breakdown of an assistant message accumulates across every API
round-trip inside the turn: each tool call re-reads the whole cached
prompt, so input/cache.read add up to several times the context window.
Every context-usage surface summed those fields, which is why the meter
could read 330% of a 1M window whose real fill was 232,872 tokens
(23.3%), and why reopening an older session jumps the readout (#2562).
The server reports the final round-trip's window as tokens.total
(optional in the message schema; opencode 1.18.18 returns it, verified
against its live /session/:id/message API). Prefer it everywhere the
window fill is displayed and fall back to summing only when the server
did not send it: contextTokensFromBreakdown in tokenUtils now owns that
rule, and the context store extractor, sync store getter, work status
panel, context sidebar, VS Code layout, mini chat, and mobile metadata
all use it instead of their own inline sums.
Fixes#2562
Branch status resolves an open PR across the whole fork network first, so a
merged fork PR can never hide an open upstream PR for the same head. Only when
no target has an open PR does the branch's newest closed/merged PR come back,
as history.
The panel shows that history as a compact note and offers creating the next PR
below it, instead of either sticking on a terminal PR or going blank after a
merge. Terminal associations stay persisted for reload continuity but are never
treated as authority: they revalidate on the discovery cadence and on focus.
History is looked up only for the branch's own remote and name, and remembered
per repo+branch, so the extra lookup cannot exhaust the route's resolve budget.
The checks summary and merge-permission lookup are skipped for a closed or
merged PR, where neither is actionable.

jsonc-parser was returning truncated trees (often only `$schema`) when
configs contained JSON5-style unquoted keys. Config mutations then backed
up and overwrote the full file with that stub. Check parse errors on read
and refuse to overwrite unparseable files on write in web and VS Code.

Claude quota only worked when the user had signed into Anthropic through
OpenCode. Credentials are now discovered from Claude Code itself first: the
macOS Keychain entry, then the Linux/WSL credentials file (honouring
CLAUDE_CONFIG_DIR), then OpenCode auth.json, then CLAUDE_CODE_OAUTH_TOKEN.
All sources stay read-only and the OAuth token is never refreshed: Anthropic
allows one live refresh token per client_id, so refreshing here would sign the
user out of Claude Code. Credentials are re-read per request instead, and an
expired token reports that Claude Code needs a sign-in rather than a bare 401.
Usage is now read from the limits[] array, so model-scoped weekly limits work
again after Anthropic stopped populating seven_day_sonnet/seven_day_opus, and
new limit kinds no longer need a code change. Adds extra-usage spend and the
plan name, and holds the last good values through Anthropic's 429s with a
cooldown and an account-keyed cache.
A server running with authentication disabled pairs and connects fine, but
the saved connection has no bearer token. Auto-connect silently bailed on
the missing token and the resume reprobe reported it as 'unreachable',
so every return to the app kicked the user to the connect screen.
Treat a saved tokenless connection as valid: probe it without a bearer and
let the probe decide — auth disabled connects, auth enabled later reports
needs-login. Bail out only when an expected token cannot be read.
A single uncaught exception (e.g. a Node-internal socket error) no longer
shuts the local server down; only a sustained storm does. The dev-tunnel
client now rejects non-http(s) base URLs cleanly instead of throwing an
uncaught exception in the connection handler.
