feat: default to Altimate Base with no consent gate; stop falling back to keyless Zen - #1361
Conversation
Since 2026-09-17, OpenCode Zen rejects keyless traffic outright ("OpenCode's
free tier can only be used from within OpenCode"), which breaks every install
that falls back to the keyless `opencode` provider with no model of its own
(360 machines in 5 days). This registers Altimate Base automatically, with no
disclosure dialog, and stops the default-model resolvers from ever falling
back to the now-broken keyless tier when Base is available.
- `FreeTier.autoRegister()` / `autoRegisterWithin(ms)` in
`packages/opencode/src/altimate/free/client.ts`: registers without a
consent token, reusing the existing lock, `inflight` dedupe, and
`registerOnce` path `registerAfterConsent` already uses. Skips (never
throws) when `ALTIMATE_BASE_AUTO_REGISTER` is `0`/`false`, no gateway URL
is configured, the user explicitly logged out (checked inside the
registration lock so a concurrent logout can't be missed), or valid
credentials already exist. `autoRegisterWithin` bounds the wait and lets a
slow attempt keep going in the background — its credentials still land on
disk for the next launch.
- Every entrypoint (`cli/cmd/serve.ts`, `cli/cmd/tui.ts`, `cli/cmd/run.ts`
outside `--attach`, `cli/cmd/acp.ts`, `cli/cmd/web.ts`) calls
`FreeTier.autoRegisterWithin()` before provider/instance state is first
built.
- `Provider.isPublicZen()` is the one shared predicate for "this is the
keyless `opencode` tier" (id `opencode`, placeholder `"public"` key, no
real key). `Provider.defaultModel()`, ACP's `defaultModelFromConfig()`, and
the TUI's `fallbackModel()`/`currentModel()`/`restoreSession()` now:
- drop the `declinedManagedBaseDefault` veto (still parsed for
compatibility, no longer consulted) — there is no working public-Zen
fallback left for a decline to protect.
- exclude Base only via a real `enabled_providers`/`disabled_providers`
verdict, never merely because a project's `config.provider` block names
some other provider.
- replace a stale persisted/session selection that resolves to public Zen
with Base once it's registered, instead of replaying a model OpenCode
Zen now rejects outright (`prompt.ts`'s `lastModel()`, ACP's
`availableModel()`, and the TUI's recents/current-model/`restoreSession`
paths).
- ACP no longer strips `altimate-free` out of the directory snapshot for a
project with an unrelated `config.provider` block (`acp/service.ts`).
- `altimate_base_registration` telemetry gets an optional
`origin: "auto" | "consent"` field; the auto path tracks the event directly
instead of calling `Telemetry.init()` (which would treat config as enabled
outside an Instance context).
Part of a 3-commit PR; part (b) removes the TUI consent dialog and
capability/consent machinery, part (c) covers the Zen error message and
rate-limit retry. Both are separate, later work.

…ottling - `provider/error.ts`: map OpenCode Zen's "can only be used from within OpenCode" 403 (keyless free tier, blocked since 2026-09-17) to a clear, non-retryable message pointing users at Altimate Base or their own provider via `/models`. Never auto-switches the model. - `altimate/free/client.ts`'s `describeRateLimit`: a `throttling_error` with "Limit type: tokens" is now retryable with the same message shape as the generic burst limit, since the per-minute token budget was raised to 1.5M/min and now really means a burst of fast turns, not an oversized request. - `provider/error.ts`: cap the `Retry-After` header passed to `session/retry.ts`'s existing retry machinery at 60s so a large gateway-reported wait can't stall a session for minutes; the user-facing message still shows the real value. - Update `altimate-base-rate-limit-messages.test.ts`, `altimate-base-harness-smoke.test.ts`, and `release-v0.11.0-adversarial.test.ts` for the new TPM classification, and add coverage for the Zen-block mapping, TPM retry classification, and the 60s Retry-After cap in `test/provider/error.test.ts`.

…inery
The product decision is fixed: no consent gate for Altimate Base. Replaces the
blocking terminal dialog with a one-line non-blocking notice, shown once per
install the first time Base becomes the active model. The disclosure wording
itself (`ALTIMATE_BASE_DISCLOSURE`) is unchanged — the gateway still logs
requests — but accepting it is no longer a precondition of registering.
- `FreeTier.register({ origin })` replaces `registerAfterConsent(token)`: no
token, still shares the lock/dedupe/`registerOnce` path with `autoRegister`.
Unlike `autoRegister`, an explicit register proceeds even after a logout —
the user asked for it.
- Deleted `altimate/free/capability.ts` (the one-shot arm/redeem consent
authority) and `altimate/free/host.ts` (the per-process registration-gate
injection it existed to protect) — nothing needs either any more.
- `altimate/free/consent.ts` keeps the `DISCLOSURE`/`HINT`/`disclosureHash()`
re-exports the notice and route still use; `createRegistrationConsentGate`
becomes `createRegistrationGate`, a plain outcome classifier with no token.
- `server.ts`: `POST /altimate/base/register` calls `FreeTier.register({
origin: "server" })` directly and accepts (but ignores)
`acceptedDisclosureSha256` for older clients. Both routes are now available
on every server with a gateway configured, not just one that provisioned a
gate — `serve.ts` no longer claims the armer or provides a gate at all.
- `cli/tui/worker.ts`'s `registerAltimateBase` RPC drops
`setAltimateBaseConsentToken` and the token param; `cli/cmd/tui.ts` no
longer mints one.
- TUI: deleted `DialogAltimateBaseConfirm`, `context/altimate-base-consent.tsx`
(the dedicated pre-SDK-context registration operation), and the startup
migration dialog trigger in `app.tsx`. Picking Altimate Base from any picker
(the welcome screen, the provider dialog, the full model catalogue) now
calls a shared `selectAltimateBase()` helper directly: register if needed →
refresh provider state → validate → select, showing a toast on failure. The
registration operation moves onto the public `sdk` context
(`AltimateBaseRegisterFn`) since there's no more consent boundary to keep it
out of; an attached TUI (no in-process worker) falls back to the HTTP route
over the same transport everything else uses.
- Telemetry: `altimate_base_registration`'s `origin` gains `"picker"` and
`"server"` (`"consent"` stays in the union for historical data). The retired
dialog's `altimate_base_confirm_shown` / `altimate_base_choice` /
`altimate_base_register_result` events keep their schema entries but are no
longer emitted by anything.
- Tests: deleted `altimate-base-armer-callsites.test.ts`,
`context/altimate-base-consent.test.tsx`, and
`cli/tui/dialog-altimate-base.test.tsx` (all tested deleted machinery).
Removed the token-forgery/capability-unforgeability tests from
`altimate-base.test.ts` and the token-redemption test from the
v0.11.1-adversarial suite; migrated every other `registerAfterConsent(
consented())` call site to `FreeTier.register({ origin: "picker" })`.
Rewrote `test/server/altimate-base-registration.test.ts` for the no-gate
routes (register works with no hash; browser-Origin is still refused on an
unsecured server).
Third and final commit of this PR; part (a) added no-consent auto-registration
and Base-over-keyless-Zen default selection, part (c) covers the Zen error
message and rate-limit retry.

…e notice Adds the two automated tests flagged as missing after the consent-dialog removal — the user-visible promises of this PR: - `test/component/select-altimate-base.test.ts`: unit-tests `selectAltimateBase()` directly (with hand-built fakes for its collaborators, since `selectModel()`'s underlying `local.model.set()` is agent-scoped and the package's component-mount fixtures don't set one up). Covers: a successful registration disposes the instance, refreshes provider state, selects `altimate-free/altimate-base`, and never opens a dialog; the same via the attached-TUI HTTP fallback (no host-injected `registerAltimateBase`); a registration failure shows an error toast and leaves the model/dialog untouched; and a registration that reports success but never actually surfaces the model in the refreshed provider list also fails closed with a toast, not a partial selection. - `test/component/altimate-base-disclosure-notice.test.tsx`: mounts the real provider stack with a single `altimate-free` provider (so `fallbackModel()` resolves to Base with nothing else to configure) and drives `useAltimateBaseDisclosureNotice()`'s kv-persisted "already shown" flag the way a real restart would (a pre-seeded `kv.json`). Confirms the notice shows exactly once — the first time Base becomes the active model — and does not reappear on a subsequent launch once the flag is set. Exported `ALTIMATE_BASE_DISCLOSURE_SHOWN_KEY` from `altimate-onboarding.tsx` (previously module-local) so the second test can seed it, the same way `ALTIMATE_BASE_MIGRATION_DECLINED_KEY` is already exported from `context/local.tsx` for the identical reason. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Three Codex review findings on the Altimate Base default-no-consent branch: - `fallbackModel()`'s implicit last-resort pick in `local.tsx` used a naive array-order `.find()` instead of mirroring `Provider.defaultModel()`'s ordering, so keyless public Zen could be picked over a registered Base, and Base could beat a provider the user actually connected depending on array position. Extracted `pickImplicitFallbackProvider()` as a pure, directly testable function that mirrors the server's ordering exactly, and added 3 unit tests covering: Base outranking Zen, a credentialed provider outranking Base, and unchanged behavior when Base isn't registered. - `dialog-provider.tsx` and `dialog-model.tsx` set the Altimate Base row's one-shot activation latch before the async `selectAltimateBase()` resolved, and never reset it on failure, permanently bricking the row for the rest of the dialog session after a single failed attempt. Reset the latch when `selectAltimateBase()` returns `false`, and added a full-render retry test confirming a failed selection can be retried and re-fires registration. - `altimate-onboarding.tsx`'s `chooseAltimateBase()` had the same bug, but on the first-run welcome picker: it returned `true` synchronously right after firing the unawaited `selectAltimateBase()` call, so `activateRow()` claimed its one-shot latch before the registration attempt was known to have failed. A failed Base registration then bricked Enter, `/` and mouse-up for the rest of the dialog session on the picker shown to users with no model at all. Reset the latch on failure the same way, keeping the double-input guard intact for the in-flight window, and added a retry test to `dialog-model-welcome.test.tsx` confirming the same row can be retried.

WARNING: Attached registration drops the server authentication headers
In attach mode, SDKProvider gives the generated client the Basic Auth headers from attach.ts, but its exposed sdk.fetch is only the raw fetch function and does not bind those headers. This direct POST therefore gets a 401 from a password-protected server even though every normal SDK request succeeds, so an attached user cannot select Altimate Base. Route this through the authenticated SDK client or expose a fetch helper that merges props.headers.

Fixed in 2ef2c8a. The SDK context now exposes the same auth headers the typed client uses, and the attached-TUI fallback merges them into the POST /altimate/base/register request. A new test checks that the Authorization header is sent.

WARNING: Explicit reconnect can inherit auto-registration's logged-out skip
This shared inflight entry can later be returned by register(), but the two operations intentionally have different logout semantics: auto-registration rejects a logout marker while explicit registration must reconnect. If the user picks Base while a startup attempt is still in flight, the explicit call joins this auto attempt and fails instead of running its explicit path. This is especially reachable after autoRegisterWithin() times out and leaves the attempt running. After joining an auto attempt that reports the logged-out skip, retry under explicit registration semantics or distinguish the two in-flight operation kinds.

Fixed in 41dc4d4. Explicit and automatic registration now have separate in-flight maps, and both still go through the same file lock. An explicit call can no longer join an automatic attempt and inherit its logged-out skip. There's a race test for this.

WARNING: Optional stale-model repair can now abort prompt creation
FreeTier.isRegistered() reads both the credential store and gateway configuration and can reject on an unreadable store or invalid configuration. This unguarded call runs when continuing any session whose last provider is opencode, so an optional migration check can prevent the existing model from being used at all. Other discovery call sites treat this read as best-effort; catch failures here and continue with item.info.model when registration state cannot be determined.

Fixed in 41dc4d4. The registration check in lastModel() is now best-effort: on error it keeps the session's model.

WARNING: Idempotent registration still tears down every active instance
FreeTier.register() returns success when a valid credential already exists, and this route subsequently treats that success as a credential change and enters the process-wide disposal path. A duplicate picker click, client retry, or already-registered attach request therefore tears down sessions, PTYs, LSPs, MCP connections, and watchers even though no credential changed. Have registration report whether it created/rotated credentials and invalidate both registries only in that case.
Reply with @kilocode-bot fix it to have Kilo Code address this issue.
There was a problem hiding this comment.
Fixed in 41dc4d4. The route compares credentials before and after register() and disposes the instance registries only when a credential was actually created or rotated. Tests cover both cases.

When altimate attach connects to a password-protected server, cli/cmd/attach.ts supplies the Basic-auth headers to SDKProvider, but this fallback bypasses the configured SDK client and invokes the raw fetch function with only Content-Type. Consequently, selecting Altimate Base after auto-registration failed or after logout receives a 401 and is reported as a generic setup failure. Merge the SDK provider headers into this request or expose the registration route through the authenticated client.

Fixed in 2ef2c8a (same as the Kilo thread above). The attached-TUI registration now sends the SDK's auth headers.

For a retryable Altimate Base throttle, the intended 60-second ceiling is bypassed when Retry-After is an HTTP date because Number(...) is non-finite and the original header is returned; it is also bypassed by retry-after-ms, which SessionRetry.delay checks before retry-after. A gateway or proxy emitting either supported representation can therefore stall the session for minutes despite this cap. Parse and clamp HTTP dates and the millisecond header as well.

On a fresh altimate run, this now registers Base and can immediately send the prompt to a request-logging provider without any disclosure, because the only new notice is a hook mounted by the interactive TUI. This also directly contradicts the shipped security FAQ, quickstart, and provider docs, which still promise that no registration occurs without an explicit confirmation defaulting to No. Users relying on those guarantees may send confidential code under materially different handling terms; surface the notice in headless flows and update the public documentation with this behavior change.

When registration or the subsequent bootstrap is slow, the user can dismiss the picker or replace it with another dialog while this async operation remains in flight. The operation then still selects Base and calls dialog.clear(), which clears the new, unrelated dialog; the removed confirmation component previously tracked disposal and checked it after every await. Add a liveness/cancellation guard, or keep the originating dialog non-dismissible until this sequence finishes.

Fixed in 2ef2c8a. selectAltimateBase() records the originating dialog and checks it after each await. If the picker was dismissed or replaced, it stops without selecting, showing a toast, or clearing the dialog. Tests cover dismiss mid-registration and replace mid-bootstrap.
| * Register at startup, automatically — no consent gate, no user action. Every entrypoint calls | ||
| * this before provider state is first built. Shares LOCK_KEY, the `inflight` dedupe map, and | ||
| * `registerOnce` with `register()` (the explicit, picker/route-triggered path), so an auto-register | ||

The claim that every entrypoint invokes this is incomplete: a repo-wide search shows that altimate agent create calls Agent.generate(), which resolves Provider.defaultModel(), and altimate review calls Provider.defaultModel() for its enabled-by-default AI lane, but neither command calls autoRegisterWithin(). On a fresh installation launched directly through either command, Base is absent from provider state, so agent creation selects the now-rejected keyless Zen model and fails, while review silently degrades to an empty AI result. Invoke auto-registration centrally before provider state is built, or add it to these model-consuming handlers.

Acknowledged, not changed; it is now residual R6 in the PR description. altimate agent create and altimate review resolve a default model without calling autoRegisterWithin(). On a fresh install where one of them is the very first command, Base isn't available yet. Any launch of tui, run, serve, acp or web registers it, and those are the entrypoints a new user reaches first.

Fixed before the takeover in 2ef2c8a. selectAltimateBase() records the originating dialog and stops after every await if the picker was dismissed or replaced, so it neither selects Base nor clears a newer dialog. This picker goes through that same helper.
…g in the Base default changes - `server.ts`: restore the outer import block's `altimate_change end` that was removed together with the `FreeTierHost` import - `acp.ts`: the auto-register import block used a single-line marker closed by an `end`; make it a `start` - `provider.ts`: drop a nested `start` inside an already-marked block in `defaultModel()` - `provider/error.ts`: the Zen rejection message and its matcher no longer name the upstream product; behavior unchanged (still scoped to the `opencode` provider) - Reword two comments that the branding audit flagged Fixes the Marker Guard and `bridge-merge` / `upstream-merge-guard` CI failures.

When continuing an opencode session in a source build without an embedded Base gateway, with an invalid gateway override, or with an unreadable/malformed credential store, FreeTier.isRegistered() rejects because it calls gatewayUrl() and reads the store without handling errors. This newly aborts lastModel() before the previous model can be returned, even though provider loading already treats the same lookup failures as Base being unavailable. Catch this lookup and treat it as false so --continue and other resume paths remain usable without Base.

Fixed before the takeover. lastModel() now calls FreeTier.isRegistered().catch(() => false), so a lookup failure is treated as unregistered and the previous model is returned.
… dedupe and idempotent register Finishes the backend half of the PR #1361 review findings: - Headless disclosure (`run`/`serve`/`acp`/`web`): the first successful AUTO registration outside the TUI now prints `ALTIMATE_BASE_DISCLOSURE` once to stderr (`consent.ts`'s `printDisclosureOnceForHeadless()`), tracked with a marker file next to the credential store so it survives across process launches. `serve` skips it when `ALTIMATE_CLI_CLIENT=datamates`, since the VS Code extension shows its own notice. - Retry cap bypass (`provider/error.ts`): the 60s cap on a retryable Base 429's `Retry-After` only clamped a numeric `retry-after` in seconds. `SessionRetry.delay()` reads `retry-after-ms` first and falls back to an HTTP-date `retry-after` — both bypassed the cap entirely. All three forms are now clamped, with 4 new tests. - Idempotent register tearing down every instance (`server.ts`): the `POST /altimate/base/register` route disposed every session/LSP/PTY/MCP connection whenever `FreeTier.register()` reported success, even when the credential on disk hadn't actually changed (its "already registered" fast path). Compares `FreeTier.credentials()` before/after and skips disposal when nothing changed, with 2 new tests. - `SessionPrompt.lastModel()`: `FreeTier.isRegistered()` can throw (unreadable store, bad config), which aborted resuming a session. Now best-effort — falls through to the unchanged model on error. - Shared in-flight dedupe (`free/client.ts`): `autoRegister()` and `register()` used one dedupe map keyed only by gateway URL, so an explicit `register()` racing an in-flight `autoRegister()` could observe autoRegister's own "logged out" skip instead of actually reconnecting. Split into `explicitInflight`/`autoInflight`, still serialized through the same `Flock` lock, with a new race test. - Repeated startup wait after a failure (`free/client.ts`): every entrypoint calls `autoRegisterWithin()` at startup, so a persistent failure (network down, gateway 429/5xx) repeated the same attempt on every new launch — these are short-lived processes, so an in-process-only backoff map never helped. The backoff deadline is now persisted to a small JSON file next to the credential store, read at the start of `autoRegister()` (including the first call in a brand-new process) and cleared on success; `register()` ignores it. 3 new tests, including one asserting the backoff survives what an in-memory map would have lost. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…icker guard Finishes the TUI half of the PR #1361 review findings: - Attached TUI registration drops auth (`altimate-onboarding.tsx`): the HTTP fallback for `registerAltimateBase()` (used when there's no host-injected worker RPC, i.e. `opencode attach`) called `sdk.fetch` directly with no auth headers, so it 401ed against a password-protected server. `sdk.tsx` now exposes the same `headers` `createOpencodeClient` already bakes into every typed SDK call; the fallback merges them in. New test asserts the Authorization header is actually sent. - Explicit model must stay authoritative (`local.tsx`'s `currentModel()`): the stale-public-Zen -> registered-Base substitution applied uniformly to whatever `fallbackModel()`/a persisted pick/an agent's own `model` resolved to — so an explicit `--model opencode/x` (or config `model`, or an agent's configured `model`) pointing at the now-broken keyless Zen tier got silently rewritten to Base instead of staying put. Split `fallbackModel()`'s explicit args/config checks into their own `explicitFallbackModel()` memo so `currentModel()` can route only the two truly implicit sources (a persisted per-agent pick, and the implicit recents/allowlist fallback) through the substitution. `Provider.defaultModel()`, ACP's `defaultModelFromConfig()`, and `SessionPrompt.lastModel()` were already correct (their explicit sources short-circuit before any substitution logic runs) — verified, not changed. New full-mount test (`explicit-model-authoritative.test.tsx`) exercises `currentModel()` itself with Base actually registered, confirming `--model opencode/x` stays put and — as a control — that the same catalogue substitutes Base when nothing explicit overrides it. - Dismissed picker (`selectAltimateBase()`): registration and bootstrap are both async; if the originating picker was dismissed or replaced while either was in flight, the function still went on to select the model and call `dialog.clear()` — closing whatever the user has open now, not the picker that started this. Snapshots the top-of-stack dialog by reference at entry and re-checks it after every await, bailing out silently the moment it no longer matches. 2 new tests (dismissed during registration, replaced during bootstrap). - Test isolation (`select-altimate-base.test.ts`): `selectAltimateBase()` calls `markSetupComplete()` on every successful path, flipping the module-global `setupComplete` signal that Bun's test runner shares across every file in the run (already handled in `local.test.ts` around its own `markSetupComplete()` calls, but missing here). Added the same `resetSetupComplete()` in `afterEach`. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Every doc still promised the retired flow — "registration only after an explicit confirmation that defaults to No" — after auto-registration with no consent dialog shipped. Updates the security FAQ, quickstart, provider docs, README, and network reference to state the new behavior (a fresh install with no model of its own registers Altimate Base automatically, the disclosure is shown once) and the actual opt-outs (`ALTIMATE_BASE_AUTO_REGISTER=0`, `altimate providers logout altimate-base`, `enabled_providers`/`disabled_providers`) — noting that only the env var stops the background registration call itself. `docs/docs/configure/providers.md` also drops the stale claim that `declinedManagedBaseDefault` still keeps public Zen ahead of registered Base for a migrating Big Pickle user — Zen's keyless tier rejects unauthenticated traffic outright now, so there's no working choice left to honor; the flag is read for backward compatibility only. `docs/docs/reference/telemetry.md`: corrected `altimate_base_registration`'s "after consent" wording, and marked `altimate_base_confirm_shown` / `altimate_base_choice` / the `altimate_base_back` picker trigger as legacy — still defined in the event schema, but no longer emitted now that the consent dialog they recorded is gone. Logging/retention wording is unchanged verbatim from `ALTIMATE_BASE_DISCLOSURE` (verified against `test/altimate/altimate-base-disclosure-claims.test.ts`, which checks the docs note stays a superset of the in-app notice).

`--base origin/main --strict` diffs against HEAD (not the working tree), so
this only surfaced after the previous two commits landed:
- `sdk.tsx`: the new `headers: props.headers,` line had its explanation on
the line above instead of a same-line marker, which the line-based checker
doesn't credit — moved to a start/end block ending on that line, matching
the sibling `registerAltimateBase` line's own trailing-marker style.
- `local.tsx`: `const fallbackModel = createMemo(() => {` is unchanged
content, but inserting `explicitFallbackModel()` above it shifted its diff
position enough that git shows it as a delete+add against origin/main
rather than pure context — flagged the same way. Added a marker comment.

Review: 2 major, 4 minor, 3 nits
The two major findings are inline: an explicit keyless-Zen selection or --model is rewritten to Base (local.tsx:696), and a headless process can use Base without the disclosure when registration finishes in the background (consent.ts:118). Both should be fixed before merge. The remaining findings are below.
Claims C1 and C3 through C8 held up under targeted attempts to break them, apart from the gaps below. The serialized snapshot-and-reload in the register route, the separate explicit/auto in-flight maps behind one shared file lock, logout-nonce rotation, and the wx disclosure claim are careful work.
Minor
1. The failure backoff is never saved when a gateway silently drops packets and run is short. packages/opencode/src/altimate/free/client.ts:318-320, 705-717; packages/opencode/src/index.ts:275
The auto-register fetch times out after REGISTER_TIMEOUT_MS = 15s, and the backoff is written only after that failure. With packets silently dropped (egress firewall, locked-down CI), a run that finishes within ~15s is killed by the global finally { process.exit() } before the attempt fails. Nothing is persisted, so every later run pays the 3s startup wait again. That includes runs using their own model (R1). This defeats the backoff added in 41dc4d4, in the environments where it matters most.
Suggestion: write a provisional backoff under BACKOFF_LOCK_KEY when autoRegisterWithin returns pending (or before the network call), and clear it on success. Alternatively, cap the auto path's fetch timeout near the 3s budget.
2. The first register-route call in each process always disposes every instance, even when registration preceded listen(). packages/opencode/src/server/server.ts:74-83, 843-848
appliedBaseCredential starts undefined. When serve/acp/web got registered or already-registered before Server.listen(), no cache can lack Base. Even so, the first successful POST /altimate/base/register (an idempotent host call, or a Base pick from a host picker) tears down sessions, LSPs, PTYs and MCP connections process-wide. C4 allows this, so it's an availability optimization rather than a broken guarantee. It's still worth doing, since it's the common case and startup already knows the answer.
Suggestion: seed appliedBaseCredential with the on-disk fingerprint when startup resolved to registered/already-registered before listen(), and never on pending. The identity check still forces a reload if the credential later changes.
3. A credential repaired outside this process can leave one directory's provider cache stale. packages/opencode/src/server/server.ts:836-847
Sequence:
- Server A reloads for credential F.
- Another process persists
rejected: true(afterREJECTED_PERSIST_THRESHOLD401s). - A opens a new directory, which caches providers without Base.
- Another process re-registers and gets the same key/URL/expiry back (no logout, so the nonce is unchanged).
- A's route reads F both before and after, so
applied && !changedskips the reload and returns success withoutstaleProviders.
Repeated registration calls can't recover this; only an explicit instance disposal or a restart can. The window is narrow.
Suggestion: add a persisted revision counter, bumped on every credential write (rejection included), to the identity. Alternatively, track the credential revision each provider cache was loaded with.
4. Four C8 retry-cap tests pass vacuously. packages/opencode/test/provider/error.test.ts:477, 488, 498, 510
In the retry-after-ms and HTTP-date cap/no-cap cases, every assertion sits inside if (result.type === "api_error") with no unconditional type check. If parseAPICallError stopped returning api_error for a Base 429, these would pass while checking nothing. They are the tests that back C8's "every Retry-After form" claim. 66056a6 fixed the same pattern in two sibling tests. The throttle tests at :412/:435/:448 are only partly affected: their message assertions are unconditional, but their retryability and header checks sit inside the same guard.
Suggestion: add expect(result.type).toBe("api_error") before each guard.
Nits
- Stale comments and dead parameters from the consent era.
provider.ts:2208, 2227, 2230-2233still describe Base as consent-gated ("naming it cannot activate it"). ThedeclinedManagedBaseDefaultparameter inacp/service.tsis kept and thenvoid-ed, and the value is still parsed byreadDefaultModelState(); marking it@deprecatedwould stop someone re-wiring it.local.tsxhas two consecutive// altimate_change endmarkers afterrestoreSession. - The public-Zen predicate is defined twice.
provider/public-zen.ts:isPublicZenandtui/src/context/local.tsx:isPublicZenProviderduplicate the same identity rule with no test tying them together. A small table-driven test over both (keyless, keyed,options: {}, non-opencode) would stop them drifting. - Worth a release note: a project
providerblock no longer keeps implicit choices off Base. Before, a non-emptyconfig.providerblock vetoed Base for implicit choices. Now Base is exempt. For example, a project pinned to a local provider that exposes no models now defaults to Base instead of failing with "no models found". This is intentional (provider.ts:2238-2245), andenabled_providers/disabled_providersare documented as the opt-out. It's still an upgrade-visible change.

MAJOR: an explicit selection of keyless Zen, including --model, is silently replaced by Base (falsifies C2)
This first branch runs substituteStaleZen() on modelStore.model[agent], but every live selection is stored there as well, not just restored or implicit picks:
app.tsx:544hands--modelto the TUI vialocal.model.set(..., { recent: true }).set()(line ~983) callsselectModel(model, { recent: true, explicit: true }), which writessetModelStore("model", a.name, model)at line 722 and recordsexplicitDefault.
So with Base registered, altimate --model opencode/<keyless-zen-model>, or deliberately picking, cycling to or favoriting a keyless Zen model, resolves here to altimate-free/altimate-base. The next prompt goes to the request-logging gateway, when the user should get the explicit "free Zen models no longer work" error. explicitDefault still names Zen. explicitFallbackModel() (line 701), the branch 2ef2c8a protected, is never reached for these selections because this branch returns first.
explicit-model-authoritative.test.tsx doesn't catch this because it never drives the model.set() handoff.
Suggestion: record where each in-memory agent selection came from (explicit set/cycle/favorite vs session restore or implicit), and apply substituteStaleZen only to non-explicit entries. Alternatively, skip substitution when explicitDefault or args.model names the same model. The regression test needs to mount the real App, or run its model.set() handoff. Mounting with ArgsProvider.model alone repeats the existing test's blind spot.
There was a problem hiding this comment.
Confirmed and fixed in 0565811. The TUI now records, per agent, whether the in-memory selection was explicit: selectModel() stores the flag alongside the model, and set(), cycle() and the favorites cycle pass explicit. currentModel() applies substituteStaleZen() to that selection only when it was not explicit, which leaves restoreSession()'s repaired pick. --model opencode/<keyless-zen> and a deliberate picker or cycle choice therefore stay on Zen and get its own error.
Test: stale-zen-cycle.test.tsx > "an explicit keyless-Zen selection, as --model hands it over, is not replaced by Base". It drives local.model.set(zen, { recent: true }), the same handoff app.tsx:544 makes for --model. It fails on 16873f0 and passes on 0565811. The companion cycling test now creates its repaired selection through restoreSession() rather than set().

MAJOR: a registration that finishes in the background can serve Base in the same headless launch with no disclosure
This check runs exactly once, right after autoRegisterWithin() in serve/run/acp/web. On a fresh non-datamates serve where registration takes longer than the 3s budget:
- startup gets
{ status: "pending" },isRegistered()is still false, and this returns without printing; - registration completes in the background (say at 4s) and writes the credential;
- the first request (say at 5s) builds the provider cache lazily, and
credentialsForLoad()now sees Base; - with no other model configured, prompts route to the request-logging gateway for the rest of the process with no notice.
run has the same, smaller window during bootstrap(). R2 ("applies on the next launch") holds for caches built before completion, but not for caches built after it in the same process. The next-launch notice (6f92853) still fires, but after data has already been sent.
Suggestion: when the startup result is pending, keep a handle to the underlying attempt (autoRegisterWithin currently drops it in the Promise.race) and call printDisclosureOnceForHeadless(true) on success, keeping the datamates skip. The wx claim already prevents double printing. That closes the missing-notice gap, but it doesn't guarantee the notice comes before the first inference, because the credential is on disk before autoRegister() returns. A strict before-use guarantee needs a check on the inference side, e.g. claim or print the marker when a Base model is first resolved in a headless process.
There was a problem hiding this comment.
Confirmed and fixed in 0565811, along the lines you suggested. autoRegisterWithin() takes an optional callback that fires when the startup wait gave up ("pending") and the same attempt then registers Base. run, acp, web and serve pass printDisclosureOnceForHeadless(true); serve passes nothing when the client is datamates. The wx marker claim keeps it to one print.
Unit tests in altimate-base-auto-register.test.ts: "reports a registration that finishes after the wait gave up" fires the callback once after a gated slow registration, and the in-budget case asserts it does not fire. End to end at 0565811: a plain serve with gateway traffic delayed 2.5 s per packet was ready at 6.0 s with no notice and registered at 10.9 s. The notice printed once at that point, and the next headless run in the same install didn't print it again.
As you note, this does not guarantee the notice precedes the first inference. The credential is on disk just before the callback runs, so a request building its provider cache in that gap could reach Base first. I've recorded that as residual R7 rather than adding an inference-side claim.
…tration in the same launch - The TUI records whether each agent's selection was explicit (`--model`, picker, cycle, favorite). `currentModel()` repairs a stale keyless-Zen selection to Base only when it was not explicit, e.g. a session restored before Base existed, so an explicit Zen choice gets Zen's own error instead of being routed to Base. - `autoRegisterWithin()` takes an optional callback for a registration that finishes after the startup wait gave up. `run`, `serve` (except for the VS Code extension), `acp` and `web` use it to print the disclosure in the same launch rather than the next.

When a user explicitly selects keyless Zen through the model picker and then restarts the TUI, model.json restores the matching recent and explicitDefault values, but this new map is initialized empty on every mount. Because the per-agent model is not persisted, currentModel() falls through to fallbackModel(), which treats the restored Zen recent as implicit and substitutes Base. Thus the explicit choice is honored only until restart and the next launch can silently use Base; initialize this state from the persisted explicit marker or make the fallback substitution consult that marker.
Useful? React with 👍 / 👎.

Accurate, but this is the intended launch-default behavior, so I've narrowed the claim instead of changing it.
After a restart, fallbackModel() deliberately skips a keyless-Zen entry in recent when Base is available, and Provider.defaultModel() does the same for headless launches. Keyless Zen no longer works, so a Zen entry in history is treated as stale and the launch default goes to registered Base.
Initializing the new map from explicitDefault would make the TUI honor that marker while the server's headless default resolution, which reads only recent, would not. An earlier round reverted exactly that kind of explicitDefault preference because the TUI and the server could then resolve different defaults from the same model.json; see the comment above the recent loop in fallbackModel().
--model and a config model are authoritative on every launch through explicitFallbackModel(). What doesn't survive a restart is only a picker, cycle or favorite choice of keyless Zen. C2 now scopes those choices to the session, and R8 records the restart behavior.

When a user picks keyless Zen in conversation A, sends a turn, opens conversation B with a recorded model, and returns to A without restarting, each navigation invokes restoreSession(), whose non-explicit selectModel() call clears this agent-keyed marker; returning to A then repairs its recorded Zen model to Base. Thus a picker choice does not remain authoritative for the current launch and can be silently rerouted after ordinary session navigation. This is fresh evidence beyond R8's restart case because no process restart or persisted recent reload is involved; retain explicitness per conversation/model rather than only per agent.
Useful? React with 👍 / 👎.

Confirmed and fixed in 51c6a8a. The TUI no longer flags the agent's current selection, which restoreSession() reset. It now keeps a launch-wide record of the models explicitly picked this launch (--model, picker, cycle, favorite). currentModel() and restoreSession() both leave a keyless-Zen model alone when it is in that record, so returning to conversation A restores its Zen model instead of rerouting it to Base.
Test: stale-zen-cycle.test.tsx > "an explicit keyless-Zen pick survives switching conversations and back". It picks Zen, restores a conversation on another model, then restores the Zen one and expects Zen. It fails on 0565811 and passes on 51c6a8a.
While writing it I found the tests were passing the shared model constants straight into the store. The store merges a newly set object into the one already there, so one call could overwrite another test's constant. They now pass copies.
The TUI now remembers which models were explicitly picked during this launch rather than flagging the agent's current selection, which session restore reset. Both `currentModel()` and `restoreSession()` leave an explicitly picked keyless-Zen model alone, so returning to a conversation doesn't reroute it to Base. Tests pass model copies, because the store merges a newly set object into the one already stored.

Accurate, but I'm keeping the model-level scope and recording it as residual R9.
Agent keying wouldn't separate the conversations in your example. Most conversations run under the same primary agent, so an agent-scoped key would still match. Separating them properly means keying by conversation, which needs extra handling for a pick made on the home screen before the conversation exists.
The effect of the current scope is narrow and errs on the safe side. It applies only to a keyless-Zen model the user explicitly chose during this launch. Another conversation recorded on that same model replays it and gets Zen's own error, which tells the user to switch to Altimate Base, instead of being moved onto the request-logging gateway without a choice. Once the TUI restarts, the record is gone and the repair applies again (R8).

Minor: a picker Zen choice isn't kept when switching agent. packages/tui/src/context/local.tsx, fallbackModel()'s recents loop.
Model selection is stored per agent, and agent.set/agent.move don't carry it over. An agent with no stored pick inherits the user's last choice through fallbackModel() → recent[0].
Suppose Base is registered and the user deliberately picks keyless Zen from /models on build, then presses Tab to plan. The recents loop skips the Zen entry because baseAvailable && isPublicZenProvider(...), without checking explicitPicks, so plan resolves to Base. A --model choice survives this path, because explicitFallbackModel() returns it. A picker, cycle or favorite choice doesn't, which the reworded C2 covers.
Suggested fix: skip a keyless-Zen recent only when it isn't in explicitPicks. Test: set(zen, { recent: true }), then agent.move(1), then assert that current() is Zen.
There was a problem hiding this comment.
Confirmed and fixed in e31844d, as you suggested. fallbackModel()'s recents loop now skips a keyless-Zen entry only when it isn't in explicitPicks. The shared substituteStaleZen() helper checks the same record, so the fallback isn't swapped to Base again afterwards. The record is now declared before fallbackModel, which reads it as soon as it's created.
Test: stale-zen-cycle.test.tsx > "an explicit keyless-Zen pick carries to another agent without its own model". It does set(zen, { recent: true }), then agent.move(1), then asserts current() is Zen. The harness now serves a second primary agent. The test fails on 51c6a8a and passes on e31844d; all 339 TUI tests pass.
…odel An agent with no stored pick inherits the most recent one through `fallbackModel()`, whose recents loop skipped a keyless-Zen entry without checking this launch's explicit picks. The loop and the shared Zen repair helper now both honor that record, so Tab to another agent keeps a deliberate Zen choice. New test covers it.

What does this PR do?
Since 2026-09-17, OpenCode Zen rejects keyless requests from Altimate Code ("OpenCode's free tier can only be used from within OpenCode"). A user with no model of their own falls back to a keyless Zen model, so every request fails. Altimate Base was the working free option, but only after a consent dialog. This PR makes Base the default that works out of the box. The commits, grouped:
