Adds st0x-issuance-client, the typed S01 client for the IAP-gated read, debug, and capital routes. This is part 1 of 5; #452 adds breakglass commands. RAI-1931

Live effect: none until S01 Identity-Aware Proxy (IAP) is available · Risk: low (no money path, no keys or IAM change, and easy to undo) · Ships: on merge, usable after RAI-1920 · Blocks: #452

Decisions

  • The bot and client share request types, not copies, so their wire contracts cannot drift. crates/dto/src/lib.rs
  • CI supplies a pre-minted ID token. The binary uses browser sign-in for humans because Google's Rust auth library rejects ID tokens from external-account credentials. .github/workflows

Proof

  • Rainix test and static passed. The TLS capture test proves the request, bearer token, response body, and exit codes.
  • Not verified: real IAP access and Google's browser sign-in end to end.

Rollout

  1. After RAI-1920, set the S01 URL and OAuth variables. Run --env staging read stuck and expect JSON with exit 0.
  2. Rollback: stop using the client. The existing bot routes and offline issuer CLI remain available.

Walkthrough

The change adds the st0x-issuance-client binary for S01 read, debug, and capital operations. It adds environment selection, Google ID-token authentication, HTTP transport, command routing, and error handling. It also adds shared email and request DTOs, updates account and admin code and OpenAPI schemas to use them, and documents the client and its configuration.

This change adds a new opt-in operator command-line client and shares request types with the server. The existing admin routes and the issuer command-line tool are unchanged. The client has no effect until the S01 IAP deployment exists, and rollback means simply not using it. No outstanding merge-blocking issue is identified.

Adds st0x-issuance-client, an operator CLI for the bot's IAP-gated /ops/{read,debug,capital} routes. It signs in with Google through a loopback PKCE flow for people, or takes a pre-minted ID token in CI. It sends that token through IAP and prints JSON, with exit codes 0, 77 and 2. The request bodies and Email move into st0x-issuance-dto, so the client and the bot share one set of types.

Overall read: the change is careful and well tested. All 19 verbs match the bot's /ops mounts in method, path, query and body. The moved Email keeps its stored deserializer, so Account event replay does not change. The loopback listener is now bounded per connection and in total, and it accepts only the redirect that carries its own state. The sign-in flow, the token cache and the failure classification are each covered by tests. The panel found no blocking defect. Two small gaps remain:

  • Symbols in request bodies are not upper-cased. The issuer CLI that this client replaces does upper-case them.
  • A 502 or 504 from the load balancer is reported as a plain failure. It does not get the warning that a write may already have been applied.

The four existing threads were checked and are not repeated here.

This PR adds st0x-issuance-client (crates/ops-client), the S01 operator client for the IAP-gated /ops/{read,debug,capital} routes, moves the operator request bodies and Email into the shared DTO crate, and specifies the client in SPEC. My overall read: ready to merge.

Since the last review (9d0eac0): the branch was rebased onto main (now on top of #451, the ALCHEMY_API_KEY change), and the merge commit was dropped. A range-diff shows all seven PR commits unchanged. The only difference is a README hunk that main had already applied. No new code is in the PR, so I found no new defects.

Earlier findings

  • Symbols were not upper-cased in JSON bodies (cli.rs): resolved. All eight UnderlyingSymbol arguments still parse through uppercase_symbol at b149a14, and lowercase_symbols_are_sent_upper_cased covers the bodies, the path and the query.
  • 502 and 504 were reported as plain failures (transport.rs): resolved. They map to OutcomeUnknown, which tells the operator to check the logs before retrying a write. The test and the SPEC failure list cover both statuses.

Threads resolved by others

  • Loopback sign-in took the first connection (auth.rs): addressed. capture_code loops on accept(), and only a request with this sign-in's own state ends the wait. Each request head is limited to 16 KiB and 10 s, and the whole wait to 5 minutes. A test covers the stray connections.
  • Redact Debug on Target/Identity (target.rs): dismissed, and the reason holds. No production code formats these types, and the Desktop client secret is not confidential.
  • End-to-end test of the client against the server (SPEC.md): dismissed, and the reason holds. A direct client-to-bot test bypasses IAP, so it would not test the real auth path. The dispatch tests pin every verb's wire request, and the staging run needs RAI-1920's load balancer.
  • Raw email in the account span and logs (src/account/api.rs): dismissed, and the reason holds. This logging existed before the PR, and the rollback log needs the email to find the account_emails row.

CI: at b149a14, test fails on tests/recovery.rs::test_mint_recovery_from_minting_state_when_receipt_exists, which waited for the restart callback and never got it. This PR does not touch that test or the recovery path. It passed at 9d0eac0 with the same PR code, and it passed six times in a row locally at b149a14 (run times varied from 1.7 s to 10 s). It looks like a timing flake, not a defect in this PR. Re-run the job before merging.

Since the last review (de5dc1e): the PR head is still de5dc1e. Nothing has changed since my last review, which approved this commit with no open findings, so there is nothing new to review.

Earlier findings (all from earlier rounds, still fixed at de5dc1e)

  • Symbols not upper-cased in JSON bodies (cli.rs): resolved. Every UnderlyingSymbol argument parses through uppercase_symbol, and lowercase_symbols_are_sent_upper_cased covers the bodies, the path and the query.
  • 502 and 504 reported as plain failures (transport.rs): resolved. classify maps them to OutcomeUnknown, which tells the operator to check the logs before retrying a write.

Threads resolved by others

  • Loopback sign-in takes the first connection (auth.rs): addressed. capture_code loops on accept() and ends the wait only for a request with this sign-in's own state. Each request head is bounded by size and time, and a test covers the stray connections.
  • Redact Debug on Target/Identity (target.rs): dismissed, and the reason holds. No production code formats these types, and the Desktop client secret is not confidential.
  • End-to-end test of the client against the server (SPEC.md): dismissed, and the reason holds. A direct client-to-bot test would bypass IAP, so it would not test the real auth path. The dispatch tests pin the wire request of every verb.
  • Raw email in the account span and logs (src/account/api.rs): dismissed, and the reason holds. This logging predates the PR, and the rollback log needs the email to find the account_emails row.
