Draft. Step 1 of the design in AgentWorkforce/relayhistory-pipeline#63. Code and test keys only: no real keys, deploys or account changes.

What changes

• POST /v1/tokens/session-directory-search exchanges a caller's verified RelayAuth token for a 60-second, single-workspace token with role: session_directory_search_worker. There is no refresh token.
• The tenant comes only from the signed subject token. The request can select only the subject's own workspace.
• A separate issuer and RS256 key with current/next/previous slots, published at /.well-known/session-directory/jwks.json with max-age=300.
• Off by default. RelayAuth refuses to start if the issuer or a key overlaps the general issuer, or if issuance is on without both.
• The mint scope is a broker scope under fix(tokens): require the exact broker scope to mint History assertions #114: matched exactly, and only a caller holding it can delegate it, so an org admin cannot create a minting key. Only a plain API key carrying that one scope can mint.
• RELAYAUTH_SESSION_DIRECTORY_BOOTSTRAP_API_KEY[_FILE] creates the first dedicated key at boot. Worker deployments have no boot step, so hosted needs its own way to create this key.
• Helm values and docs/self-hosting.md.

Differences from the design

• No OIDC discovery. The AWS proof runs self-hosted PostgREST, which reads keys from jwt-secret. Hosted Supabase would still need discovery.
• API keys are not org-bound. RelayHistory serves every org with one key, so design test 23's "other-org key is refused" does not apply. The org always comes from the subject.

Known limits

• The rate limit (120 mints a minute per subject and workspace) is per process.
• Plain HTTP: the API key and subject token travel in the request, so this endpoint must not be called over a plain-http in-cluster Service until RelayAuth has TLS.
• This will conflict lightly with feat(server): migration grants and a grant-bound migration assertion #110 in env.ts and tokens.ts.
• The exchange is single-workspace. Multi-workspace issuance is a separate design in docs(hoopdb): design the session directory tenant JWT issuer relayhistory-pipeline#63, not approved for code.

Validation

Server suite 706/706 after merging main, including 15 new tests in session-directory-issuer.test.ts. Server typecheck is clean. helm template renders the new env vars. Real PostgREST coverage is in the 96BullSessions follow-up.

Walkthrough

RelayAuth adds optional session-directory search token issuance with dedicated signing-key configuration, a scoped bootstrap API key, a minting endpoint, and a separate JWKS endpoint. The change also adds startup validation, subject-token checks, rate limiting, persistence and audit recording, tests, Helm settings, and self-hosting documentation.

Changes: Session-directory search tokens

Layer / File(s)	Summary
Configuration and bootstrap key packages/server/src/env.ts, packages/server/src/server.ts, packages/server/src/lib/bootstrap-api-key.ts, charts/relayauth/values.yaml, charts/relayauth/templates/deployment.yaml, packages/server/src/__tests__/test-helpers.ts, packages/server/src/__tests__/session-directory-issuer.test.ts	Adds session-directory configuration and secret settings. Startup validates issuer settings and can provision a dedicated bootstrap key with only the mint scope. Bootstrap key handling accepts a configurable scope.
Issuer validation and JWKS packages/server/src/lib/session-directory-issuer.ts, packages/server/src/routes/jwks.ts, packages/server/src/__tests__/session-directory-issuer.test.ts, docs/self-hosting.md	Adds subject validation, tenant normalization, claim construction, RS256 signing, and configuration checks for a dedicated issuer. The new JWKS endpoint publishes its keys or returns 404 when none are configured. Tests and documentation cover issuer settings, key publication, and token requirements.
Minting endpoint and validation packages/server/src/routes/tokens.ts, packages/server/src/lib/auth.ts, packages/server/src/__tests__/session-directory-issuer.test.ts	Adds POST /session-directory-search. The route checks the API key scope, verifies and validates the subject token, applies a per-subject, workspace, and organization rate limit, then signs and records the token and issuance audit entry. Tests cover accepted requests and refusal cases.

The endpoint can report a successful exchange while returning an already-expired token. This narrow case should be fixed before merge or explicitly accepted.

Landing review at 8cf31d1. Merges are approved by Khaliq (2026-10-31, lead session).

Merge with main (6ccf423). No text conflicts. #119 breaks this PR's tests, though: since #119, only a plain API key holding a broker literal may delegate it. The issuer harness minted its key through a bearer token that carried the literal, so 11 tests returned 403. Fixed in 8cf31d1: the operator is now a seeded plain API key. A new test pins that a bearer token holding relayauth:assertion:create:session-directory-search cannot delegate it, either onto an API key or onto a workspace token.

Adversarial pass.

• The tenant comes only from the verified general-issuer subject.
• The request can select only the subject's own workspace.
• The subject must be an access token with rth:read, an accepted audience, and not a migration or search class. Revocation is checked, including workspace lineage.
• Minting needs a plain API key carrying exactly the one scope.
• The issuer and keys are refused at boot and on every mint if they overlap the general ones.
• exp is at most iat + 60 and never later than the subject's own exp.

Composition with 96BullSessions #72. The issued claims (iss = the configured issuer, aud = session-directory-search, a lifetime of 1 to 60s, one workspace id) satisfy the RPC's token pins. The environment must seed sessions.session_directory_search_token_policy with this issuer.

Validation, local.

🟥 Broker assertions grant cross-tenant search access

With both broker keys, a caller can exchange a relayhistory_assertion minted for any tenant into a directory search token. refuseSubject accepts its audience and rth:read scope, bypassing the intended user-token requirement.

Not changed, by design. The design (96BullSessions docs/session-directory-tenant-issuer.md, "Threats") treats Cloud's per-workspace relayhistory_assertion tokens as the real subject tokens for this exchange. It also records that the relayhistory-assertion key can mint for any org, so it remains an any-org path until #110's narrowing lands. Refusing that class here would refuse every legitimate caller. The exchange still never widens a subject: one workspace, the subject's own org, and exp capped at the subject's.

[devin-ai-integration]

🟨 Search credentials travel over plaintext by default

When called through the chart's default HTTP Service, /session-directory-search accepts the minting key and subject token in cleartext. Anyone observing that traffic can replay both credentials.

This is a known limit, documented in the PR body and docs/self-hosting.md: the endpoint must not be called over a plain-http in-cluster Service until RelayAuth has TLS. Issuance is off by default (RELAYAUTH_SESSION_DIRECTORY_ISSUANCE must be exactly true), so nothing reaches it until an operator enables it on a TLS path.

[greptile-apps]

Confidence Score: 5/5

[High impact] The PR appears safe to merge; both previous findings are addressed and no new blocking issue was found.

Summary

Adds a separate issuer for short-lived, single-workspace session-directory search tokens.

• RelayAuth exchanges a verified subject token for a short-lived session-search token.
• Search tokens use a separate issuer and published signing keys.
• RelayAuth can create the dedicated search-minting key at startup.
