What does this PR do?

Lets a non-terminal host register Altimate Base.

registerAfterConsent only acts on a token armed through a module-private authority, and the armer is claimable once per process. Previously only the TUI worker claimed it, so the VS Code extension — which talks HTTP to altimate serve — could never mint a Base credential: the model appears in GET /provider's all but never in connected, and selecting it failed the next prompt with model altimate-base not found.

Two routes:

  • GET /altimate/base/disclosure — read-only. Returns the consent text, the picker hint, registered, and the SHA-256 the client must echo back. It arms nothing.
  • POST /altimate/base/register — checks the echoed hash, then mints, arms and redeems the consent token in one operation, registers, and calls Instance.disposeAll(). Returns staleProviders: true if that disposal fails, since the credential is written but provider lists may be stale.

What the hash does and does not prove. It makes "the caller holds the current disclosure text" checkable — a client rendering superseded wording cannot register people against text they were never shown, so a copy change like #1268 actually takes effect. It does not prove a human read anything: any caller can GET the disclosure and echo the hash. Over HTTP, "the user saw this" remains an assertion by the caller. (An earlier version of this description claimed otherwise; that was wrong and is retracted in the comments below.)

disposeAll() rather than dispose(): the Base credential is one global file, but Instance.dispose() evicts only cache.delete(Instance.directory) — the directory the request happened to carry — so a multi-root workspace or a second window kept a provider list in which Base was still disconnected.

The gate is injected by the entrypoint (cli/cmd/serve.ts) rather than claimed in the route, because issueArmer() throws on a second claim and the TUI worker already holds it while serving HTTP from the same process. A host that injects nothing — the TUI worker — gets 501 rather than a second surface that could bypass its own dialog. capability.ts owns the canonical statement of who may claim it, and a test enforces that list against the source.

Registration is also refused when an Origin header is present and no server password is set: a page on a CORS-allowed origin can reach this port without being a local process, which is a different reachability class from "can already execute tools here". Native clients send no Origin. Note this does not stop a non-browser local caller; requiring a password unconditionally was rejected because the extension never sets OPENCODE_SERVER_PASSWORD, so it would disable the feature for its whole audience.

The disclosure text has one definition in packages/core, since packages/tui and packages/opencode cannot import each other. #1268's copy change is merged in and reaches both surfaces through it.

How did you verify your code works?

Three new/changed suites, 20 tests:

  • test/server/altimate-base-registration.test.ts (11) — both 501-when-no-gate paths, GET arming nothing, mint/arm/redeem token identity, stale-hash refusal without touching the gate, case-insensitive hash, the 403 browser refusal, failure-taxonomy passthrough, validator rejection, provide() single-shot.
  • test/altimate/altimate-base-disclosure-claims.test.ts (6) — the gate carries logging / model use / don't-send-secrets / rate limits whatever the wording; the docs remain a superset; the known "may be logged" vs "are logged" deviation is pinned so it cannot drift further silently.
  • test/altimate/altimate-base-armer-callsites.test.ts (3) — the issueArmer() call-site set matches the canonical docstring, so adding a claimer fails here instead of quietly falsifying prose.

packages/tui Base dialog suite: 8, now including one that asserts which option is default by cursor position (it previously checked only that "(default)" appeared somewhere, so it passed unchanged through an inversion of the default and back) and one covering Return declining.

bun turbo typecheck clean across 13 packages.

End-to-end against a running altimate serve pointed at a local self-signed stub gateway: forged, malformed and replayed tokens all rejected; a valid request registers and altimate-free joins connected only after disposal. Also end-to-end in code-server against the production gateway via the companion PR, including a deliberate 45-second pause before accepting — which the first revision of this PR failed, because it armed the token at disclosure-fetch time against a 30s TTL.

Summary by CodeRabbit

  • User Experience

    • Updated Altimate Base consent wording to clarify that usage can be rate limited.
    • Removed persistent per-installation identifier details from the consent prompt.
    • Standardized provider and model picker subtitles to “free · no signup · rate limited.”
  • Registration

    • Improved registration handling with clearer responses when unavailable or when consent wording is outdated.
    • Registration cleanup is now more reliable after successful activation.
  • Bug Fixes

    • Fixed onboarding behavior so declining Altimate Base consent does not trigger registration.

Altimate Base could only be registered from the TUI. `registerAfterConsent`
redeems a token against a module-private consent authority, and the only way to
arm one is `FreeTierCapability.issueArmer()`, claimed at TUI worker boot. The
VS Code extension talks HTTP to `altimate serve`, so it had no way to mint a Base
credential: the model is advertised in `GET /provider`'s `all` but never appears
in `connected`, and selecting it failed the next prompt with "model altimate-base
not found".

- Add `GET /altimate/base/disclosure` — returns the consent text and arms one
  single-use token. The only place an HTTP caller can obtain a token.
- Add `POST /altimate/base/register` — redeems the token through the existing
  consent gate and returns its result taxonomy (`rate_limited` | `unavailable` |
  `network` | `error`) as a 200 body, the same values the TUI dialog renders.
- Add `altimate/free/host.ts` — the entrypoint injects the gate, consumers read
  it. A route cannot claim `issueArmer()` itself: it throws on a second call, and
  the TUI worker already claims it while serving HTTP from the same process, so a
  route-level claim would break the TUI worker and any test importing both the
  server and the Base test harness.
- `cli/cmd/serve.ts` claims the capability and injects the gate. The TUI worker
  deliberately does not, so its server answers 501 rather than offering a second
  registration surface that bypasses its own disclosure dialog.
- Move the disclosure text to `@opencode-ai/core/altimate-base-disclosure` so the
  TUI dialog and the HTTP route share one definition. `packages/tui` depends on
  core, not on `opencode`, so core is the only home both can import; a new leaf
  file adds no upstream rebase surface.

Registering over HTTP makes "the disclosure was actually shown" an assertion by
the caller rather than a property enforced by construction, as it is in the TUI.
Mitigated by minting a token only in the disclosure response, single use, and the
consent store's existing 30s TTL. This is not a new privilege boundary — anything
that can reach this server can already execute tools — but it is a deliberately
narrower guarantee.

Verified against a running `altimate serve` pointed at a local stub gateway: a
forged token, a malformed token and a replayed token are all rejected; an issued
token registers, writes the credential, and `altimate-free` joins `connected`
after `POST /instance/dispose` (the provider loader caches its credential read,
so the dispose is required). Also verified end to end in code-server against the
production gateway. `bun turbo typecheck` clean across 13 packages; Base suites
47/47; TUI Base dialog suite 7/7.

📝 Walkthrough

Walkthrough

Altimate Base disclosure text and picker hints are centralized. The serve command provides a single-shot registration gate. HTTP routes validate disclosure hashes, register through the host gate, and dispose both instance registries after successful registration.

Changes

Altimate Base registration

Layer / File(s) Summary
Shared disclosure contract
packages/core/src/altimate-base-disclosure.ts, packages/opencode/src/altimate/free/consent.ts, packages/opencode/src/altimate/free/client.ts, packages/tui/src/component/*, packages/opencode/test/altimate/altimate-base-disclosure-claims.test.ts
The disclosure and picker hint are defined in core. Consent documentation distinguishes disclosure hashes from human consent. TUI components reuse the shared constants. Tests validate the disclosure claims and hint.
Host registration gate
packages/opencode/src/altimate/free/host.ts, packages/opencode/src/altimate/free/capability.ts, packages/opencode/src/cli/cmd/serve.ts, packages/opencode/src/cli/tui/worker.ts
The host module exposes a single-shot registration gate. The serve command installs it before server initialization and registers consented tokens.
HTTP disclosure and registration routes
packages/opencode/src/server/server.ts, packages/opencode/test/server/altimate-base-registration.test.ts
The routes use host capability checks and delegated registration. Successful registration disposes both instance registries. Tests cover unsupported hosts, validation, token flow, browser-origin rejection, and cleanup results.
Entrypoint and dialog validation
packages/opencode/test/altimate/altimate-base-armer-callsites.test.ts, packages/tui/test/cli/tui/dialog-altimate-base.test.tsx
Tests enforce the allowed armer and redeemer callers. TUI tests verify the default opt-out selection and cancellation behavior.

Priority: ➖ Normal — Schedule the HTTP registration change because it adds Altimate Base onboarding for non-TUI hosts and affects disclosure, token handling, and process-wide provider disposal.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 6d582

The new HTTP registration flow can expose registration material through caches and permit unauthenticated registration requests that omit Origin on unsecured reachable servers. These security and consent-path risks should be resolved before merge; the documentation-test gap is secondary.

Comment @coderabbitai help to get the list of available commands.

A three-model review (Claude, Gemini 3.1 Pro, GPT 5.2 Codex) returned NEEDS
REVISION unanimously. This addresses every engine-side finding.

The important one: `GET /altimate/base/disclosure` armed the consent token, so
`ConsentCapabilityStore`'s 30s TTL started when the disclosure was FETCHED rather
than when the user accepted it. Anyone who actually read the text before
consenting was rejected with "consent expired" — the flow failed precisely for
users exercising due diligence on a privacy disclosure, and passed for anyone who
clicked through blind. The TUI never had this because it mints and redeems inside
its accept handler (`cli/cmd/tui.ts:253-257`). A code comment in the extension
claiming a stale card "re-fetches" was also simply false.

Adopts the restructure all three reviewers recommended:

- `GET /altimate/base/disclosure` is now read-only. It returns the text, the
  picker hint, `registered`, and the SHA-256 the client must echo back. It arms
  nothing, which also restores GET's safety semantics and removes the token-
  eviction race (the store holds at most 16 pending tokens and evicts FIFO).
- `POST /altimate/base/register` mints, arms and redeems the token in one
  operation, so no TTL can elapse mid-flow. It requires the caller to echo the
  disclosure hash, which upgrades "the user saw the current disclosure" from an
  assertion by the caller to something the server checks: a client that never
  fetched the disclosure, or one showing superseded text, cannot register.
- The register route now disposes the instance itself. The provider loader caches
  its credential read, so previously every client had to remember a follow-up
  `POST /instance/dispose` — and if that call failed, the client reported failure
  even though the credential was on disk, while other attached windows kept
  seeing `connected: false`.
- Refuse registration when an `Origin` header is present and no server password
  is set. A page on a CORS-allowed origin can reach this port without being a
  local process, which is a different reachability class from "can already
  execute tools here". Native clients send no `Origin`, so they are unaffected.
- `FreeTierHost.provide()` is single-shot and throws on reuse, matching
  `issueArmer`/`issueRedeemer`. Last-write-wins let in-process code swap the gate
  out from under the routes after `serve` installed it.
- Both routes now declare `describeRoute` metadata, so they appear in the
  generated OpenAPI spec like every other route.
- The picker hint joins the disclosure in
  `@opencode-ai/core/altimate-base-disclosure`. It had drifted into three
  variants across `dialog-provider.tsx`, `dialog-model.tsx` and the extension.

Adds `test/server/altimate-base-registration.test.ts` — the previous revision
shipped 146 lines with no tests, and nothing covered the 501-when-no-gate path
that is the entire safety story for the TUI worker. 11 tests: both 501 paths,
GET arming nothing, mint/arm/redeem identity, stale-hash refusal without touching
the gate, case-insensitive hash, the 403 browser refusal, failure passthrough,
validator rejection, and `provide()` single-shot.

Verification: `bun turbo typecheck` clean across 13 packages; new suite 11/11;
Base suites 58/58; TUI Base dialog suite 7/7.

@saravmajestic — deep review below. Net: sound design, safe to merge after two fixes (one real TTL correctness risk, one test-coverage gap). The security narrowing is real but consciously made and correctly bounded.

I traced the full mechanism first (ConsentCapabilityStore: 64-hex tokens, 30s TTL, single-use consume, ≤16 pending, unforgeable once-per-process armer/redeemer).

What's done right (non-trivial)

  • Unforgeability is preserved. The route can't mint an accepted token out of thin air — it arms through the same private productionAuthority via the injected issueArmer() closure, and registerAfterConsent redeems via issueRedeemer(). A forged/self-armed token still fails consume(). The PR weakens only "a human saw the text," not "the token is authentic." That distinction is the crux and it's right.
  • Host-injection instead of a route-level claim is correct — issueArmer() throws on a second claim and the TUI worker already holds it in-process. Claiming at the serve entrypoint + 501 from the TUI worker (rather than a second bypass surface) is the right shape.
  • Single definition of the disclosure in core; honest, specific security note in the PR body.

Issues to address

[P1 — correctness/UX] The 30s TTL now spans human read-and-accept time.
In the TUI, arm→redeem is instantaneous (armed at accept). Here, GET /disclosure arms the token at disclosure-show time and hands it to the extension; the human then reads and clicks accept, and only then does POST /register redeem. DEFAULT_TTL_MS = 30_000, so a user who reads the privacy text for >30s gets consent expired and registration fails. The E2E likely passed because the click was fast. Fix options: raise the TTL for this flow, arm at accept-time (a small arm step just before register), or have the extension re-GET + retry on expiry. This is the one I'd block on.

[P1 — test coverage] The security-critical properties are only verified by manual curl, not automated tests.
Please add server route tests for: 501 when no gate is injected (the TUI-worker bypass guard), forged/expired token → ok:false, single-use enforced (second redeem fails), and the outcome taxonomy. These are exactly the invariants a future refactor could silently break; the manual curl in the PR body isn't a regression guard.

[P2] GET has a side effect (arms a token).
A side-effecting GET is a REST smell — prefetch/CSRF can churn token slots (harmless alone, but burns 1 of the 16-token bound per call). Consider issuing the token on an explicit step. Minor: the route comment frames the token as "armed here and nowhere else, single-use" — accurate on single-use, but the store holds up to 16 pending (maxPending), evicting FIFO, not one slot.

[P2] FreeTierHost.provide() is exported and last-writer-wins.
Any importer can replace the gate. It can't inject a working bypass (no second armer available; redeem still enforces consent), so worst case is DoS (replace with undefined/broken → 501/failures). Low severity, but a stray/duplicate call silently swaps the process's registration gate — worth a guard or a comment that only the entrypoint may call it.

[P2] console.error in serve.ts vs log.warn in the route — use the project logger for consistency.

Heads-up: conflicts with open PR #1268 (disclosure-text change)

PR #1268 (per a product decision today) removes the Logs are linked to a persistent per-installation identifier. line and softens Usage is rate limitedUsage can be rate limited in ALTIMATE_BASE_DISCLOSURE. This PR moves that constant into packages/core/.../altimate-base-disclosure.ts with the old wording. They'll conflict:

  • Whichever merges second must reconcile.
  • If this PR lands first, that copy change must be re-applied to the new core file (the TUI constant becomes a re-export), and the core file's comment — which asserts it "discloses that requests are linkable across launches" — must be updated, since that becomes false once the per-install line is removed.

I'll handle the rebase on the other PR once we pick a merge order.

Security narrowing — accept, with two conditions

Turning "disclosure shown" into a caller assertion is acceptable for a first-party extension, given the token is authentic-only and this isn't a new privilege boundary. Two conditions:

  1. The companion extension must actually render the disclosure before POST — verify that in its PR; this PR's guarantee leans entirely on it.
  2. Consider whether a consent-minting route should require server auth (refuse when OPENCODE_SERVER_PASSWORD is unset). Today an unsecured serve lets any local caller silently register + opt the user into logging — "can already run tools" covers exec, not the silent data-logging opt-in.

Tip: disable this comment in your organization's Code Review settings.

One conflict, in `packages/tui/src/component/altimate-onboarding.tsx`: #1268
changed the disclosure copy (dropped the per-install-id sentence, softened
"Usage is rate limited" to "Usage can be rate limited") on the constant this
branch had just moved into `@opencode-ai/core/altimate-base-disclosure`.

Resolved by keeping this branch's structure (the TUI re-exports the shared
constant) and adopting main's new wording in the core definition, along with its
improved rationale comment. So #1268's copy change now applies to the HTTP
disclosure route as well, which is the point of having one definition.

The route tests reference `FreeTierConsent.DISCLOSURE` rather than a literal, so
they picked the new text up with no change. Also brings in main's Altimate Base
header-timeout fixes (#1260, plus the parsing hardening), which addressed the
"Provider response headers timed out after 10000ms" failures.

Verified after merge: `bun turbo typecheck` clean across 13 packages; TUI Base
dialog suite 7/7 (including #1268's new guard that the per-install-id line stays
out of the gate); engine route suite 11/11.

Thanks for updating your PR! It now meets our contributing guidelines. 👍

Review P2: the gate's onUnexpectedError used console.error while the routes use
log.warn. Both now go through Log.create({ service: "serve" }), matching
serve-upgrade-check.ts next door.

Thanks — this was a genuinely useful review. Both P1s and all four P2s are addressed, plus the #1268 reconciliation you flagged. Independently, a three-model panel (Gemini 3.1 Pro, GPT 5.2 Codex, Claude) hit your P1 TTL finding and your P1 test-coverage finding as its own top two, which was a good confirmation signal.

P1 — TTL spanning human read time. Fixed by your second option, arming at accept time. GET /altimate/base/disclosure is now read-only and returns no token at all; POST /altimate/base/register mints, arms and redeems in one operation, so no TTL can elapse mid-flow. I went a step further than a bare arm-before-register: the client echoes back the SHA-256 of the disclosure it displayed and the server verifies it against the canonical text. That converts "a human saw the text" from a pure caller assertion into something checkable — a client that never fetched the disclosure, or one showing superseded wording, cannot register. It also happens to close your P2 GET-side-effect point, and it removes the extension's need to know about instance caching, since the route now disposes itself.

You were right that the E2E passed on speed. Playwright clicked in about two seconds.

P1 — test coverage. packages/opencode/test/server/altimate-base-registration.test.ts, 11 tests, covering exactly the invariants you listed: 501 on both routes when no gate is injected (the TUI-worker bypass guard), stale/forged hash rejected without the gate being touched, mint/arm/redeem token identity, the failure taxonomy passing through intact, plus the 403 browser refusal, validator rejection, and provide() single-shot.

P2 — provide() last-writer-wins. Now single-shot, throws on reuse, matching issueArmer/issueRedeemer. Your DoS-only severity read was correct, and that is exactly why it wasn't worth leaving as-is for no benefit.

P2 — the maxPending comment. You were right that it misdescribed the bound as one slot when the store holds up to 16 and evicts FIFO. The comment is gone along with the token it described.

P2 — console.error in serve.ts. Now Log.create({ service: "serve" }), matching serve-upgrade-check.ts.

#1268. Merged. Kept this branch's structure (the TUI re-exports the shared constant) and adopted main's new wording in the core definition, so that copy change now lands on the HTTP route too — which is the argument for one definition. I also fixed the core comment you specifically predicted would become false: it no longer claims the gate discloses cross-launch linkage, and points at the docs "Data handling" note instead. The route tests reference FreeTierConsent.DISCLOSURE rather than a literal, so they picked the new text up unchanged.

Your two conditions.

  1. The extension must render the disclosure before POST. It does — the card fetches, renders, and only then can accept fire. And this no longer rests on trust: the hash check means a POST without a preceding fetch of the current text fails. Worth reviewing in fix: replace npm glob/minimatch with Bun.Glob — fixes 52 CI test failures #460 all the same.

  2. Require server auth on a consent-minting route. I could not adopt this as literally stated, and I want to be explicit rather than quietly skip it: the extension never sets OPENCODE_SERVER_PASSWORD (checked across src/ — nothing sets it), so refusing when it is unset would disable the feature for every extension user, which is the entire audience. What I did instead is refuse when an Origin header is present and no password is set. That targets the reachability class that is genuinely new — a page on a CORS-allowed origin can hit this port without being a local process — while leaving native clients, which send no Origin, working. A local CLI on an unsecured server can still register, so your concern is narrowed rather than eliminated. If you want the stricter rule, it needs the extension to start passing a password, which is a larger change I'd rather do deliberately than smuggle in here.

Also picked up main's header-timeout fixes (#1260 and the parsing hardening) in the merge, which resolve the headers timed out after 10000ms failures seen while testing this.

Re-verified after all of the above: bun turbo typecheck clean across 13 packages, new suite 11/11, Base suites 58/58, TUI Base dialog 7/7.

SUGGESTION: FreeTierHost.provide() installs process-wide module state with no teardown, so the "no gate injected" 501 assertions are order-dependent and fragile.

beforeAll here arms the single-shot gate, but neither afterEach nor an afterAll resets it. As the file's own TOPOLOGY NOTE acknowledges, bun test can load several suite files into one worker, so the 501 tests in the first describe block only pass because (a) that block is declared first and (b) nothing else in the worker has called provide(). A future server test file running in the same worker — or a --rerun-each/watch run — would either see the gate already provided (silently flipping the 501 assertions to 200) or make beforeAll throw "already provided". Per test/server/AGENTS.md ("restore state in finalizers"), consider a test-only reset (e.g. an afterAll that clears the gate) so the 501 path is deterministic regardless of ordering.

Remove the process-order dependency from this test suite.

FreeTierHost.provide() changes process-wide state for the remaining worker lifetime. The afterEach cleanup does not restore that state. Another suite in the same Bun worker can inherit this gate or fail on its own provide() call.

Inject the gate into a test-local app, or add a test-only reset with teardown and install the gate per test. As per coding guidelines, tests using similar shared state must provide teardown and isolation safe for parallel bun test execution.

…ants

Two statements in the previous commits on this branch were wrong, and are corrected
both in the code and in the record:

1. "server-side dispose also refreshes other windows attached to the same `serve`
   process" — false. `Instance.dispose()` only evicts `cache.delete(directory)` for
   the directory the request carried, so a multi-root workspace or a second window
   kept a provider list in which Base was still disconnected. The route now calls
   `Instance.disposeAll()`, and returns `staleProviders: true` when disposal fails
   rather than reporting plain success over a stale list.

2. The disclosure-hash check "converts 'the user was shown the current disclosure'
   from an assertion by the caller into something checkable" — overstated. It makes
   *"the caller holds the current text"* checkable: a client rendering superseded
   wording cannot register, which is worth having, but any caller can GET the
   disclosure and echo the hash. Whether a human read it remains an assertion, as
   the first reviewer originally said. `consent.ts` and `server.ts` now say so.

Also, the claim about who may arm the consent authority had been paraphrased in
three files and gone stale in two when `serve` became a second claimer.
`capability.ts` now owns the canonical statement and lists both entrypoints;
`client.ts` and `worker.ts` point at it instead of restating it.

`test/altimate/altimate-base-armer-callsites.test.ts` enforces that list against
the source, so adding a claimer fails there and forces the docstring to be revised
with it. It strips comments before matching — the first version counted prose in
`host.ts` as a call site.

`test/altimate/altimate-base-disclosure-claims.test.ts` covers the other axis that
had no mechanism: the gate versus the fuller "Data handling" note in
docs/docs/configure/providers.md. It asserts the gate carries logging, model use,
don't-send-secrets and rate limits whatever the wording, that the docs remain a
superset, and it pins the known "may be logged" / "are logged" deviation so it
cannot drift further unnoticed.

The TUI dialog test now asserts WHICH option is default by checking the cursor
position. It previously checked only that the string "(default)" appeared somewhere,
so it passed unchanged through an inversion of the default and back — it asserted
its own name away. A companion test covers Return declining; that path was
exercised nowhere, and `pressKey("return")` sends the literal characters r,e,t,u,r,n
(the Enter key is the uppercase `RETURN` KeyCodes name).

Verification: `bun turbo typecheck` clean across 13 packages; Base and route suites
67/67; TUI Base dialog suite 8/8.

Correcting two claims I made earlier on this PR. Both were wrong, and both are now fixed in code as well as in the record.

1. "Server-side dispose also refreshes other windows attached to the same serve process." False. Instance.dispose() only evicts cache.delete(directory) for the directory the request happened to carry (packages/opencode/src/project/instance.ts:141-147); disposeAll() is what iterates every cached instance. So a multi-root workspace, or a second window on one serve, kept a provider list in which Base was still disconnected. The route now calls disposeAll(), and returns staleProviders: true when disposal fails rather than reporting plain success over a stale list.

2. "The hash check converts 'the user was shown the current disclosure' from an assertion by the caller into something checkable." Overstated. It makes "the caller holds the current disclosure text" checkable — a client rendering superseded wording cannot register, which is worth having and does mean a copy change like #1268 takes effect. But any caller can GET the disclosure and echo the hash back; whether a human read it remains an assertion, exactly as @anandgupta42 originally characterised it. consent.ts and the route comment now say that plainly.

Relatedly, the claim about who may arm the consent authority had been paraphrased in three files and went stale in two of them when serve became a second claimer — including the client.ts docstring I had quoted as evidence. capability.ts now owns the canonical statement and lists both entrypoints; the others point at it. test/altimate/altimate-base-armer-callsites.test.ts enforces that list against the source, so adding a claimer fails there instead of quietly falsifying the prose.

Your two P1s and all four P2s from the first review are addressed. The remaining known deviation is the one you'd expect: the gate says "may be logged" where providers.md says "are logged" — pre-existing from #1268, kept per product decision, now pinned by a test so it cannot drift further silently.

WARNING: Instance.disposeAll() tears down every instance — including unrelated active sessions and every connected client's event stream — to invalidate a single global credential cache.

disposeAll() (project/instance.ts:148) iterates all cached instances and runs the full Instance.dispose() path on each: State.dispose(directory) awaits every per-directory state disposer (session state included), disposeInstance(directory) runs all registered disposers, and emit(directory) broadcasts server.instance.disposed. The /event SSE handler closes its stream on any server.instance.disposed event (server.ts:630), so a registration in one window of a multi-window serve disposes every other window's instance state and disconnects their event streams.

The state that actually changed is one credential file; only the per-directory provider/credential cache needs to go stale. Consider a targeted invalidation (e.g. a Provider-scoped invalidation keyed on the Base credential) rather than a full instance teardown.

Multi-model consensus review

Reviewed by Claude + GPT-5.4-Codex + Kimi K2.5 + MiniMax M2.7 + GLM-5.1 + Qwen 3.6 + MiMo V2 Pro (Gemini/Antigravity sat this round out — quota-locked; Kimi crashed mid-review due to host disk space, not a code problem). Two independently-verified MAJOR issues below are requesting changes; everything else is minor polish that doesn't need to block merge.

Requesting changes on

  1. FreeTierHost.current() leaks the raw mint capability to any in-process importer (inline comment on host.ts). This defeats the "only one entrypoint can ever arm the authority" invariant that capability.ts's own docstring claims — any code path that imports FreeTierHost, not just the disclosure-gated HTTP route, can mint a Base credential.
  2. Instance.disposeAll() targets the wrong/incomplete registry while being simultaneously too broad (inline comment on server.ts). It won't refresh provider state for directories only touched through the typed /api/* bridge (a separate InstanceStore), while tearing down active sessions/PTYs/MCP connections in every other window on the same serve process.

Minor findings (non-blocking, worth a follow-up)

Testing

  • No test exercises the staleProviders: true branch (when Instance.disposeAll() rejects after a successful registration) — server.ts:839-846. Flagged independently by 4 of 6 reviewers; every other branch in this route has direct coverage, so this is the one gap in an otherwise thorough test file.
  • altimate-base-registration.test.ts is order-dependent across the whole bun test process (the "no gate injected" block must run before the gate is provided). The comment explains why, but a bun test config change or file split could silently reorder suites and break it invisibly.
  • No test for the "server password set + browser Origin present" combination on POST /altimate/base/register — the code's own comment says this combination should be allowed (basicAuth already covers it), but nothing asserts that.
  • No test for concurrent POST /altimate/base/register requests exercising the inflight dedup in client.ts.

Design

  • GET /altimate/base/disclosure doesn't carry the same Origin check POST /altimate/base/register has. Low impact (disclosure text is intentionally public, the hash is derived from public text, and the only other field is a registered boolean) — but worth a one-line comment on why it's intentionally omitted, or add the same guard for consistency, since a reviewer will keep re-noticing the asymmetry otherwise.
  • GET .../disclosure's registered field silently returns false on a gateway misconfiguration (FreeTier.isRegistered().catch(() => false)), which is indistinguishable from a genuinely-unregistered install. A caller can't tell "not registered" from "couldn't check."

Nits

  • disclosureHash() recomputes SHA-256 on every call rather than memoizing the (constant) result.
  • acceptedDisclosureSha256 validator accepts an empty string, which just falls through to the normal "stale hash" response — harmless, but a min(64) on the schema would give a clearer 400 for a client bug.
  • A couple of NIT-level polish items across models: a redundant type assertion in the disclosure route's registered field, an unsafe type assertion in one test helper, and the OpenAPI description for GET /disclosure doesn't mention the registered field.

What's genuinely strong here

  • The disclosure text now has a single source of truth (packages/core/src/altimate-base-disclosure.ts), closing a copy-drift bug this feature had hit repeatedly across earlier rounds.
  • altimate-base-armer-callsites.test.ts turns "which entrypoints may claim issueArmer()" from a comment into an enforced invariant — genuinely good pattern, worth replicating elsewhere.
  • GET is correctly read-only (mint+arm+redeem now happen atomically inside POST) — the PR's own comment explains the prior bug this fixes (TTL starting on disclosure-fetch, not on accept).
  • The TUI test fix for "which option is default" (asserting the actual selected row, not just that the word "(default)" appears) plus the new Return-key regression test are good, specific catches.
  • Error handling in createRegistrationConsentGate.register() is exhaustive — nothing escapes as an unhandled rejection into the new HTTP handler.

Consensus review: Claude, GPT-5.4-Codex, MiniMax M2.7, GLM-5.1, Qwen 3.6, MiMo V2 Pro (6 participants; Kimi K2.5 and Gemini 3.1 Pro did not return usable output this round).

MAJOR — Security / Design

current() returns the full Registration object — including setToken(), which closes over the real production armer, and register(), which redeems against the real production authority.

Any in-process code that imports FreeTierHost (not just this route, and not just code that has passed the disclosure-hash/origin checks in server.ts) can do:

const gate = FreeTierHost.current()
gate?.setToken({ token: "anything" })
await gate?.register({ token: "anything" })

...and mint a Base credential without ever going through GET /altimate/base/disclosure or the acceptedDisclosureSha256 check. That defeats the invariant capability.ts's own docstring claims for this armer/redeemer pair — that no in-process code other than the entrypoint that claimed issueArmer() can ever produce a token registerAfterConsent accepts. Here, the entrypoint still claims it correctly (once, in serve.ts), but then hands out an object that re-exposes the same power to everyone downstream.

Suggest narrowing what current() returns to something that can't be misused as a raw mint primitive — e.g. a single registerWithDisclosure(acceptedDisclosureSha256: string): Promise<RegistrationResult> that performs the hash check inside host.ts itself (mint token → verify hash → arm → redeem, all in one call), rather than handing the caller setToken/register directly and trusting every future caller to redo the hash check correctly. That would make the HTTP route's own hash check redundant-but-safe instead of load-bearing.

MAJOR — Logic Error / Design

Two separate concerns with calling the legacy Instance.disposeAll() here:

1. It may not actually fix the staleness it's meant to fix. /api/* traffic is forwarded via forwardHttpApiBridge (server.ts:204) before the legacy Instance.provide middleware runs (server.ts:~285), and that typed API path is backed by a separate InstanceStore (project/instance-store.ts), not the legacy Instance registry this call disposes. A directory/window that was only ever touched through /api/* won't be in the legacy Instance cache, so this call can't invalidate its cached provider state — which is exactly the "other window keeps showing Base as disconnected" case the surrounding comment says this fixes.

2. It's simultaneously broader than it needs to be. Instance.disposeAll() tears down every Instance.state entry process-wide — session prompt state, LSPs, PTYs, plugins, schedulers, file watchers, MCP connections — and emits server.instance.disposed, closing event streams for every other legacy-backed window on this serve instance. So a user registering Base in one window can interrupt active work in every other window attached to the same server, purely to refresh a provider list.

If a full instance-wide reset really is required today, that's a legitimate trade-off worth stating explicitly in the route's describeRoute description (right now a client has no way to know a registration call might disrupt unrelated sessions) — but the fix for concern #1 is separate from accepting the blast radius in #2: even accepting the broad reset, it should be reaching InstanceStore's directories too, or the /api/*-only case stays broken regardless of how disruptive the workaround is.

…egistries

Addresses the two blocking review findings on this PR.

`FreeTierHost.current()` returned the whole gate — `setToken`, closing over the
real armer, and `register`, redeeming against the real authority — so any module
importing it held a raw mint primitive and could register without going near the
disclosure, in any order. It is replaced by `canRegister()` plus
`registerWithAcceptedDisclosure()`, which hash-verifies and then mints, arms and
redeems in a single call inside `host.ts`. There is no ordering for a caller to
get wrong and no primitive to borrow.

This is deliberately not claimed as a trust boundary: `registerWithAcceptedDisclosure`
is exported and the hash is a SHA-256 of public text, so in-process code can still
cause a registration. What it closes is accidental misuse and the drift of
re-implementing the check per call site. The module comment says so plainly.

The register route disposed only the legacy `Instance` registry. `/api/*` is
forwarded to the typed HttpApi bridge before that middleware runs and is backed by
a separate `InstanceStore`, so a directory reached only through `/api/*` kept its
stale provider state — exactly the "other window still shows Base as disconnected"
case the disposal exists to prevent. Both registries are now disposed, and
`staleProviders: true` is returned if either fails.

`describeRoute` now states the blast radius: disposal is process-wide and tears
down instance-scoped state (sessions, LSPs, PTYs, MCP connections, file watchers)
in every attached window. Narrowing that to a targeted `Provider.state`
invalidation needs changes in `provider.ts` and `state.ts`, outside this feature;
tracked separately.

Also corrects a docstring in `client.ts` that still located the disclosure-hash
check in the register route after it moved into `host.ts`.

Verified: 20 Altimate Base tests and 8 TUI dialog tests pass; no type errors in the
changed files. End-to-end against a freshly built binary — a stale hash is refused
without minting, and a successful registration connects `altimate-free` immediately.

Thanks — both blocking findings are fixed in 3692084, plus the minors that were cheap. Taking them in turn.

1. FreeTierHost.current() leaked the raw mint capability — fixed

You were right that the entrypoint claimed the armer correctly and then handed the same power to every importer. current() is gone. host.ts now exposes only:

  • canRegister(): boolean
  • registerWithAcceptedDisclosure(acceptedDisclosureSha256): Promise<RegisterOutcome>

which hash-verifies and then mints, arms and redeems, all inside the module — your suggested shape. The route can no longer mint without checking, and there is no setToken/register pair to borrow.

One thing I want to state rather than let the diff imply: this is not a trust boundary against in-process code. registerWithAcceptedDisclosure is exported and the hash is a SHA-256 of public text that anyone can recompute via FreeTierConsent.disclosureHash(), so in-process code can still cause a registration — it just cannot bypass the documented precondition. What actually improved is that there is one audited path instead of a capability handed to every importer, and no per-call-site re-implementation of the check to drift. The module comment now says exactly that, because an earlier draft of it overclaimed the closure and that is the kind of thing this feature keeps getting wrong.

Verified: POST /altimate/base/register with a wrong hash is refused and no credential is written.

2. Instance.disposeAll() targeted the wrong/incomplete registry — fixed, with the breadth called out

Your first concern was correct and I could reproduce the reasoning: /api/* is forwarded to the typed HttpApi bridge before the legacy Instance.provide middleware runs, and that path is backed by InstanceStore. A directory reached only through /api/* was therefore not in the registry being disposed. Both are now disposed, via the existing AppRuntime.runPromise(InstanceStore.Service.use(...)) pattern already used by routes/tui.ts, and staleProviders: true is returned if either fails.

Your second concern — that this is simultaneously too broad — I have not fixed, deliberately, and I want to be straight about why. A later review round confirmed your point with a specific mechanism: session/prompt.ts's state teardown calls item.abort.abort(), so registering in one window aborts in-flight generations and kills PTYs in every other window on that serve. The right fix is the targeted one you implied: invalidate Provider.state rather than tearing down the instance. State.invalidate already exists and Provider's state has no disposer, so it would be safe — but Provider's init is an anonymous arrow, so it needs naming and exporting in provider.ts plus a State.invalidateAll in state.ts. Both are shared hot-path files outside this feature, and the instruction on this PR is to keep it to the feature. So it is going to a separate ticket.

What I did do is take your suggestion to state the trade-off where a client can see it. describeRoute now says disposal is process-wide, names what it tears down (sessions, LSPs, PTYs, MCP connections, file watchers), and explains what staleProviders: true means.

Minors

  • Docs/design asymmetry on GET /disclosure having no Origin check — left as-is, and worth stating the reasoning since you predicted a reviewer would keep re-noticing it: the route is read-only, serialises public constants plus a boolean, and performs no I/O beyond one .catch-wrapped disk read. Adding the guard would imply it protects something it does not.
  • client.ts docstring — this one was actually wrong and is fixed: it still located the disclosure-hash check "in the register route" after the check moved into host.ts.
  • registered: false on a gateway misconfiguration being indistinguishable from genuinely unregistered — agreed, not addressed. The extension side is unaffected in practice because it fails closed either way now, but the ambiguity is real.
  • disclosureHash() recomputing, min(64) on the validator, the OpenAPI description omitting registered — not addressed; low value against the churn, happy to take them if you would rather they landed here.

Testing gaps you flagged

Still open, and I would rather say so than quietly leave them: no test covers the staleProviders: true branch, the order-dependence of altimate-base-registration.test.ts across the whole bun test process is unchanged, and there is no test for password-plus-Origin or for concurrent POST /register exercising the inflight dedup. The disposal branch is now harder to fake than before, since it needs both registries to fail.

Current state: 20 Altimate Base tests and 8 TUI dialog tests pass, no type errors in the changed files. Verified end-to-end against a freshly built binary — stale hash refused without minting, and a successful registration reports altimate-free as connected on the very next /provider call.

SUGGESTION: Redundant nested altimate_change markers

The InstanceStore/AppRuntime imports (lines 46–47) already sit inside the outer altimate_change block that opens at line 32 (Altimate-only server endpoints) and closes at line 50, so the nested start/end pair at lines 45/48 is redundant. Marker Guard only checks coverage; dropping the inner pair leaves the imports still marked without the overlap.

SUGGESTION: Reuse InstanceRuntime.disposeAllInstances() instead of inlining this Effect call

AppRuntime.runPromise(InstanceStore.Service.use((store) => store.disposeAll())) duplicates the existing bridge InstanceRuntime.disposeAllInstances() (packages/opencode/src/project/instance-runtime.ts:12). Routing through it drops the newly added InstanceStore and AppRuntime imports (used nowhere else in this file) and keeps disposal going through the one shared helper:

Suggested change
AppRuntime.runPromise(InstanceStore.Service.use((store) => store.disposeAll())).then(
InstanceRuntime.disposeAllInstances().then(

(also add import { InstanceRuntime } from "../project/instance-runtime" and remove the now-unused InstanceStore/AppRuntime imports).

P3: Route this disposal through InstanceRuntime.disposeAllInstances() instead of duplicating its AppRuntime.runPromise(InstanceStore.Service.use(...)) implementation. Keep the shared bridge as the single entry point for disposing the InstanceStore registry.

P3: Remove the nested altimate_change markers around these imports; the surrounding Altimate server block already covers them, so the extra pair adds no coverage and makes the change boundaries harder to maintain.

P3: The docs-superset test reuses the broad REQUIRED regexes against the whole providers.md file, so two of the four claims are not actually validated against the "Data handling" note. /secret|confidential/i matches AWS_SECRET_ACCESS_KEY, GITHUB_TOKEN lacks ... secret, etc. scattered across the doc, and /rate.?limit/i matches the unrelated "rate limits and abuse protection" (line 52) and "rate limiting" (line 107), not just the note. As a result the test's core guarantee the docs disclose what the gate summarises is silently unenforced for the secrets and rate-limiting terms. Scope those assertions to the Data handling section (e.g. read from the **Data handling:** marker through the next ** marker) or use more specific patterns, so the test fails when the note is trimmed.

Re-review — both blocking findings verified fixed

Verified 3692084 against the tree myself (not just the description): read the diff, ran bun test test/server/altimate-base-registration.test.ts test/altimate/altimate-base-armer-callsites.test.ts test/altimate/altimate-base-disclosure-claims.test.ts (20/20 pass), ran the full test/altimate/ suite (5115 pass, 2 unrelated pre-existing failures in sample-setup.test.ts that touch neither this PR's files nor its feature area), and typechecked packages/opencode (the only errors are pre-existing, in dialog-move-session.tsx, untouched by this PR).

1. FreeTierHost.current() capability leak — fixed. current() is gone. host.ts now exposes only canRegister(): boolean and registerWithAcceptedDisclosure(hash): Promise<RegisterOutcome>, which verifies the hash and then mints/arms/redeems, all inside the module. There's no setToken/register pair left to borrow, so a caller can no longer skip the check by reordering calls. The new module comment is appropriately honest about what this does and doesn't guarantee (not a trust boundary against in-process code — the real boundary is the process itself) rather than overclaiming, which is exactly right.

2. Instance.disposeAll() wrong/incomplete registry — fixed. The route now disposes both the legacy Instance registry and InstanceStore (via the existing AppRuntime.runPromise(InstanceStore.Service.use(...)) pattern already used in routes/tui.ts — confirmed this isn't a novel construct), in parallel, and reports staleProviders: true if either fails. This closes the "directory only reached through /api/* stays stale" gap I flagged.

On the blast-radius half of finding #2 — deliberately not fixed, and that's fine. The reply traced the actual mechanism (session/prompt.ts's teardown calls item.abort.abort(), so this does interrupt other windows' in-flight generations and PTYs) and correctly scoped the real fix (Provider.state invalidation, not full instance disposal) as touching shared hot-path files outside this feature — deferred to a separate ticket, with the trade-off now stated in the route's own describeRoute description so API consumers aren't surprised by it. That's a legitimate scope boundary, not a dodge.

Remaining open items — all non-blocking, all disclosed rather than hidden: the staleProviders test gap, test order-dependence, no password+Origin test, no concurrent-registration test, GET disclosure's missing Origin check (reasoned: read-only, no I/O, public data only), and the registered: false-on-misconfig ambiguity. None of these were silently dropped — the author's reply names each one explicitly as still open. Worth a follow-up PR for the test gaps given how much of the rest of this feature is unusually well-tested, but nothing here should block merge.

Approving.


Re-review by Claude, verifying the fix commit against the prior consensus round's two MAJOR findings.

🤖 Generated with Claude Code

Marker Guard failed on this PR. `const log = Log.create({ service: "serve" })` sat
just after the marker block that imports `Log`, so it read as unmarked custom code
in an upstream-shared file and would not be protected from an upstream overwrite.

Gives it its own marker pair rather than folding it into the import block, so the
reason it exists — the Base registration gate's `onUnexpectedError` hook — is
recorded where the code is.
