42f6287911 feat(byok): add organization-wide key inheritance (#6834)
* feat(byok): add organization key management

* feat(byok): inherit organization keys at runtime

* feat(byok): add organization scope to BYOK settings

* fix(byok): refresh org key state after mutations

* fix(byok): hide stale inherited status badges

* chore(db): drop colliding byok migration ahead of staging merge

Staging independently claimed 0293. Remove ours so the merge is clean;
it is regenerated at the next free index right after.

* chore(db): regenerate byok migration at 0296

Staging claimed 0293-0295 during the merge; the regenerated SQL is
byte-identical to the dropped 0293.

* docs(byok): document organization scope, precedence, and the full provider list

The BYOK section described workspace-scoped keys only. Add the organization
scope, its Enterprise requirement, the per-provider precedence rule, what an
entitlement lapse does, and the Pi sandbox exposure. Refresh the provider
table from the settings page, which had drifted from 14 to 34 entries.

* feat(byok): open organization keys to every organization plan

Organization BYOK was gated on Enterprise, but an organization is the only
thing that can hold the keys, so every plan that can own an organization
should qualify — Pro for Teams, Max for Teams, and Enterprise.

Add checkOrgPlan/resolveOrganizationPlan beside the Enterprise pair rather
than widening checkEnterprisePlan, so the Enterprise-only gates (Access
Control, whitelabeling) are untouched, and restore
resolveOrganizationEnterprisePlan to module-private now that BYOK no longer
needs it.

* perf(byok): cache the organization entitlement, not the key material

getBYOKKey runs once per agent block and once per hosted-capable tool call,
so a loop over N items resolved N times — and each organization-inheriting
resolution paid three sequential billing queries on top of the two key reads.

Split the two reads by staleness tolerance. Key rows stay fresh, because
revocation must be immediate. The entitlement is a billing gate that tolerates
bounded staleness in the harmless direction (a lapsed organization keeps using
its own key for <=60s), so cache it per organization with an in-flight share so
concurrent blocks issue one query set. The management surfaces keep reading it
fresh, so an organization that just upgraded is never told otherwise.

Also run the block check and subscription read in parallel inside
resolveOrganizationPlan, and carry the resolved scope on BYOKKeyResult so a log
line can say whether a run used the workspace's key or an inherited one.

* feat(byok): let workspaces store the Z.ai and Cohere keys the runtime reads

Both ids were already in the BYOK contract enum and both are resolved at
execution time — getApiKeyWithBYOK reaches 'zai' (GLM models are in the hosted
catalog, so the BYOK branch runs), and 'cohere' backs both the Embeddings block
and Knowledge Base reranking — but neither appeared in the settings list, so
there was no way to store the key either path looks for.

Cohere had no icon; add one from the official multi-color mark so it stays
legible on a light and a dark page.

Cohere's embed-v4.0 is kbEligible:false, so the description says 'Embeddings
and Knowledge Base reranking' rather than claiming KB embeddings.

* improvement(byok): shorten the workspace scope chip to 'Workspace'

It sits beside 'Organization', so the scope reads from the pair; 'This'
only added width.

* fix(byok): do not cache a billing outage as an unentitled organization

resolveOrganizationPlan maps a failed billing read to false, which is
indistinguishable from a real plan lapse. The entitlement cache stored that,
so one transient outage held the gate shut for the full TTL and every
inheriting run silently fell back to a metered hosted key — and the cache's
rejection path, which exists to prevent exactly this, was unreachable.

Give the resolver the onError option its neighbours already have and let the
cached read ask for 'throw', so a failure stays out of the cache and the next
resolution retries. Behavior for the call that saw the error is unchanged:
getBYOKKey still fails closed.

Reported by Cursor Bugbot.

* fix(byok): propagate the subscription read's failure too

The previous commit threaded onError through resolveOrganizationPlan's own
catch, but getOrganizationSubscriptionUsable soft-fails to null on its own, so
a failed subscription read still arrived as an ordinary 'no usable
subscription' and returned a successful false — which the entitlement cache
then stored for the full TTL. Thread the option into that call as well.

Test it at the billing layer rather than the cache layer: the entitlement test
mocks resolveOrganizationPlan wholesale, so it could never have caught this.
Verified the new test fails against the previous commit.

* refactor(byok): cache the entitlement with LRUCache, like copilot entitlements

The hand-rolled version reinvented three things the codebase already has a
canonical answer for. lru-cache is a declared dependency of apps/sim and
lib/copilot/entitlements.ts already caches an entitlement with it — by storing
the in-flight Promise, which is what makes concurrent callers collapse onto one
resolution with no in-flight bookkeeping at all. TTL and the size bound come
from the library.

That removes the second Map, the manual eviction (and its interaction with an
in-flight entry), and the dead value-while-refreshing state: 23 executable
lines. The one thing the library does not cover is dropping a rejected promise
so a billing outage is not cached for the TTL, which is kept and pinned by a
test that fails without it.

TTL expiry is no longer re-tested — that is the library's behavior, not ours,
and lru-cache reads its clock at module load so faking timers never moved it.

* refactor(byok): coalesce the entitlement read with the shared singleflight

lib/concurrency/singleflight.ts is the codebase's coalescing primitive and
oauth/credential-service.ts already pairs it with a read-through cache. Adopting
that shape fixes a case caching the promise directly did not: a *hung* billing
read wedged every caller for the full 60s TTL, where coalesceLocally evicts and
rejects at its settle deadline.

It also removes the hand-rolled rejection eviction — the cache is written only
on the success path, so an outage leaves no entry by construction.

The cache now holds booleans, which introduces the one trap worth a test: a
truthiness check would read a cached false as a miss and re-query billing on
every resolution for lapsed organizations. Pinned.

* fix(byok): keep an abandoned entitlement producer from writing the cache

coalesceLocally does not cancel a producer it timed out — its docstring says so
explicitly — so writing the cache from inside the producer let a late billing
result overwrite a fresher answer a retry had already cached, and hold it for a
full TTL.

Move the write onto the value the caller actually received. A caller that timed
out throws before reaching it, so an abandoned producer now resolves into
nothing. The test reproduces the overwrite and fails against the previous shape.
