fix(auth): let a long build or deploy wait sign in again when its token expires (BE-15858)

[james00012]

TL;DR: A build or deployment wait from the command line, such as comfy build release create --watch or comfy deploy up --watch, now keeps going past the fifteen-minute life of its sign-in token instead of failing with a not-authenticated error while the work carries on.

Closes BE-15858.

Why

The builder and deploy clients read the stored sign-in once, when the command starts, and sent that token on every request. The token lasts fifteen minutes, so every wait that polled past it failed, and the developer had to poll again by hand.

Loading

• auth · deploy client: after a 401 forces the shared refresh, retries once, and keeps the new token for later requests
• auth · builder client: sends all nine of its requests through one sender with the same retry
• auth · credentials: returns a refreshed access token only when it differs from the one refused

Landing it

• Revert is clean: one commit, no stored state.
• A client handed a token directly, as COMFY_BUILDER_TOKEN does, never refreshes; a fatal refresh clears the stored sign-in exactly as the ComfyUI client's does.

Validation

• Development environment: against staging comfy-builder and comfy-deploy, a client built from a stand-in for the stored sign-in, whose first token the services refused with a 401, forced one refresh, retried with the new token and got 200; comfy build ls exited 0 that way, the deploy client's next request reused the new token with no second refresh, and a client handed the refused token directly got deploy_not_signed_in with no refresh.
• Unit: 12 of the 15 new tests fail on main and pass here, the other 3 guard what must not change; three more pin the signed-out refresh, the retried create's Idempotency-Key and the build command's sign-in hint; 7,612 tests pass and the one failure is identical on main.

Not run: A token expiring naturally at fifteen minutes inside a real wait: the refusal came from a token with a broken signature, which the services answer with the same 401, so the client path is the same.; comfy deploy run --wait, which keeps its own copy of the token and is filed as BE-15890..

📝 Walkthrough

Walkthrough

Stored-session deploy and builder clients now refresh access tokens after HTTP 401 responses and retry once. Directly supplied tokens remain unchanged. Build 401 responses now report build_not_signed_in with context-specific hints.

Changes

Session refresh

Layer / File(s)	Summary
Deploy token refresh comfy_cli/credentials.py, comfy_cli/deploy_api.py, tests/comfy_cli/test_session_refresh.py	Stored-session deploy clients refresh their token after a 401 and retry once. Direct tokens remain unchanged. Tests cover retries, polling, failed refreshes, repeated 401 responses, idempotency headers, and sign-out behavior.
Builder request refresh comfy_cli/builder_api.py, tests/comfy_cli/test_session_refresh.py	Builder operations use the same refresh-and-retry behavior. Tests cover operation retries, token reuse, repeated 401 responses, and directly supplied tokens.
Unauthenticated build reporting comfy_cli/command/build.py, CHANGELOG.md, tests/comfy_cli/test_session_refresh.py	Builder 401 responses now emit build_not_signed_in. Stored-session callers receive a comfy cloud login hint. COMFY_BUILDER_TOKEN callers receive a token replacement hint. The changelog records the updated build and deployment watch behavior.

Approving. Reads as: a deploy or builder client built from the stored sign-in refreshes it after a 401 and retries once. Head 6d90e54, judged as comfy-cli's owner.

Optional

• Contract: a builder 401 after a fatal refresh showed a bare build_builder_error with no sign-in hint comfy_cli/command/build.py:2459. Fixed in 6d90e54 as build_not_signed_in.
• Tests: nothing pinned the signed-out refresh or the retried create's Idempotency-Key tests/comfy_cli/test_session_refresh.py:190. Fixed in 6d90e54.
• Modularity: the ten-line retry exists in both clients and a third form in the ComfyUI client comfy_cli/builder_api.py:88. Noted; one helper once a fourth caller appears.

Out of scope

• Correctness: deploy run copies the token into its job and asset clients once, so a run past fifteen minutes still expires comfy_cli/command/deploy_run.py:201. Handed up for its own ticket.

Clean: Scope, Verbosity, Resilience, Access, Reachability, Rollout.
Native review: 0 findings, folded into the list above.
Checked: the retry reaches all four wait commands, and a token passed in directly never refreshes.

Approving at 6d90e54.

Checks

• Ran the new suite in a worktree: tests/comfy_cli/test_session_refresh.py 18 passed, and the wider
  -k "builder or deploy or credential or oauth" selection 762 passed.
• Confirmed every wait holds one client for its whole run, so the token really was fixed until now:
  comfy build release logs --follow builds its client once at comfy_cli/command/build.py:2883, and
  comfy deploy up --watch hands its one client to _poll_deployment (comfy_cli/command/deploy.py:273).
• Confirmed no request escapes the new sender: builder_api.py has request_json only inside _send
  (lines 90, 98), deploy_api.py only inside _send's closure (line 113); the one direct requests call is
  the presigned blob upload, which carries no bearer.
• Followed the "safe for every method" claim into the servers rather than taking the comment's word: comfy-builder
  raises 401 only in apiserver/httpkit/identity.go:37,42,55 and comfy-deploy only in
  apiserver/httpkit/identity.go:18 + apiserver/authz/service_account_auth.go:60-75, all middleware, no handler
  caller. A 401 is answered before the handler acts, so replaying the DELETE, PATCH and POST calls is safe.
• Checked replace(self.target, ...): Target is a frozen dataclass of plain fields, no init=False, no
  __post_init__ (comfy_cli/target.py:25-39), so the swap keeps every other field.
• Checked the no-new-token guard against oauth.ensure_fresh_session: a transient failure and a lock timeout both
  return the same stale session (comfy_cli/cloud/oauth.py:688-693,744-753), so refreshed_access_token returns
  None and the 401 surfaces instead of a second doomed request.

Findings

• Not blocking. The new 401 message tells the one caller that cannot follow it to sign in again.
  comfy_cli/command/build.py:2459 answers every builder 401 with the comfy cloud login hint, including the
  COMFY_BUILDER_TOKEN path your own docstring at line 2317 describes as the agent service or CI forwarding a
  JWT. That caller has no stored session, so signing in does nothing for it; its fix is a new injected token.
  Reproduced with COMFY_BUILDER_TOKEN set against a server answering 401: comfy --json build ls prints
  build_not_signed_in with run comfy cloud login first. The new test deletes the env var first
  (tests/comfy_cli/test_session_refresh.py:224), so the injected case is not covered. _report_builder_error
  could read the env var the way _builder_client does and point that caller at its own token.

Reviewed at 3596579. The approval at 6d90e54 stands; this is only a re-check of the push.

Checks

• The push is the rebase onto cac8769 plus one test line. 6d90e54 is not an ancestor of 3596579, so the
  raw range diff is mostly feat(comfy-cli): push prints its save's warnings and holds a release on a model link warning (BE-15875) #901 and fix(deploy): list every location the compute catalog sells in (BE-15857) #898; comparing the PR's own content instead (159c229..6d90e54 against
  cac8769..3596579, both +330/-21 over the same six files) the two are byte-identical except
  tests/comfy_cli/test_session_refresh.py:69, now calling create_build_response for feat(comfy-cli): push prints its save's warnings and holds a release on a model link warning (BE-15875) #901's rename.
• The rebase kept that rename: comfy_cli/builder_api.py:144 defines create_build_response only, and
  grep -rn "create_build(" comfy_cli tests at this head returns nothing, so no caller is left on the old name.
• The 401 branch and refreshed_access_token are untouched (comfy_cli/command/build.py:2532-2538,
  comfy_cli/credentials.py), so every check from the 6d90e54 pass still holds.
• Ran in a worktree at this head: tests/comfy_cli/test_session_refresh.py 18 passed, and
  test_builder_api.py + command/test_build.py + command/test_build_push_release.py, the suites the rename
  reaches, 198 passed.
• The red Run Tests on GPU Runners (linux) is tests/e2e/test_e2e_uv_compile.py::test_progressive_conflict
  and ::test_node_uv_sync_standalone_conflict, both on ComfyUI-Manager's Conflicting packages (by node pack):
  line. No auth path, unrelated to this PR.

Findings

• Not blocking, carried from 6d90e54 and still open. comfy_cli/command/build.py:2532 still answers every
  builder 401 with build_not_signed_in and the hint run comfy cloud login first, including the
  COMFY_BUILDER_TOKEN path your docstring at comfy_cli/command/build.py:2389 describes as the agent service
  or CI forwarding its own JWT. That caller has no stored session to sign back into; its fix is a new injected
  token. tests/comfy_cli/test_session_refresh.py:224 still deletes the env var first, so the injected case
  stays uncovered.

No new finding from the push.
