Fixes #2859.

The production auto-deploy helper hard-failed when CP returned HTTP 502 for the hongming canary redeploy-fleet call. 502/503/504 are typically transient gateway/upstream flakes (SSM, ECS), so the whole fleet rollout should not halt on a single unclassified gateway error.

Changes:

• redeploy_scoped() now retries HTTP 502/503/504 up to 3 times with 5s/10s/20s backoff, emitting ::warning:: step annotations.
• _raise_for_redeploy_result() surfaces the CP error body (error/message/truncated JSON) in the RuntimeError so the operator sees the tenant-level reason instead of just the status code.
• Added pytest coverage for retry-success, retry-exhausted, no-retry on non-transient 500, and error-body surfacing.

Test plan:

• python -m pytest .gitea/scripts/tests/test_prod_auto_deploy.py — 46 passed locally.
• CI will exercise the full lint + test suite.
• On the next production auto-deploy, a transient 502 against the canary should be retried instead of immediately halting the rollout.

Fixes #2859. The production auto-deploy helper hard-failed when CP returned HTTP 502 for the `hongming` canary `redeploy-fleet` call. 502/503/504 are typically transient gateway/upstream flakes (SSM, ECS), so the whole fleet rollout should not halt on a single unclassified gateway error. Changes: - `redeploy_scoped()` now retries HTTP 502/503/504 up to 3 times with 5s/10s/20s backoff, emitting `::warning::` step annotations. - `_raise_for_redeploy_result()` surfaces the CP error body (`error`/`message`/truncated JSON) in the RuntimeError so the operator sees the tenant-level reason instead of just the status code. - Added pytest coverage for retry-success, retry-exhausted, no-retry on non-transient 500, and error-body surfacing. Test plan: - `python -m pytest .gitea/scripts/tests/test_prod_auto_deploy.py` — 46 passed locally. - CI will exercise the full lint + test suite. - On the next production auto-deploy, a transient 502 against the canary should be retried instead of immediately halting the rollout.

REQUEST_CHANGES on head 227e33c7ac.

Required core CI is green on the exact head (CI / all-required, E2E API Smoke Test, Handlers Postgres Integration, and E2E Peer Visibility are present+success; the local-provision real-image failure is advisory). The prod-auto-deploy tests also ran in Ops Scripts Tests.

Blocking findings:

1. Retry loop sleeps after the final allowed attempt and logs a retry that will never happen. redeploy_scoped() iterates over [5, 10, 20]; on the third transient response it prints attempt 3/3; retrying in 20s, sleeps 20 seconds, then exits the loop and returns the failure without making another request. That is bounded, but the backoff is not sane: it delays surfacing the terminal CP error and the warning is misleading. Make the last transient response return immediately, or define the contract as initial attempt + 3 retries and actually perform the fourth call after the 20s backoff. Update the tests so they would fail on a terminal sleep-without-retry.

2. The transient 502/503/504 diagnostics are still too thin for the operator path this PR is fixing. The warning includes status and only_slugs, but not the endpoint URL/path or CP response body. _raise_for_redeploy_result() surfaces the body only after the final result is handed to the caller; interim transient warnings still hide the reason for each retry, and the tests do not assert body/endpoint logging. Include the endpoint and a bounded/truncated body detail in the retry warning (without secrets), and pin that in tests.

3. Scope drift: this PR is described/reviewed as the #2859 prod deploy helper change, but the diff also changes .gitea/workflows/local-provision-e2e.yml, tests/e2e/test_local_provision_lifecycle_e2e.sh, and workspace-server/internal/provisioner/* for #2851 advertise-host behavior. Please split or remove those unrelated local-provision changes from this PR so the deploy-helper fix can be reviewed and landed independently.

The retry concept is right, and non-transient 500 no-retry plus CP error-body surfacing are directionally covered, but the terminal backoff/diagnostic behavior and unrelated #2851 changes need cleanup before approval.

REQUEST_CHANGES on 227e33c7ac.

The bounded retry direction is right, and exact-head required/code CI is green (CI / all-required, Platform Go, E2E API Smoke, Handlers Postgres, Peer Visibility, Local Provision stub). The known staging-LLM and real-image advisory reds are not blockers.

Blocker: redeploy_scoped() sleeps after the final transient response even though no further CP call will be made. The loop at .gitea/scripts/prod-auto-deploy.py:234-246 iterates over [5, 10, 20], calls CP three times, and on the third 502/503/504 prints “retrying in 20s”, sleeps 20s, then immediately returns last_status,last_body. That wastes 20s on every exhausted transient failure and the log says it is retrying when it is not. The test currently pins this bad behavior (test_redeploy_scoped_gives_up_after_max_retries asserts sleeps == [5, 10, 20]).

Please make the semantics explicit and load-bearing: either three total attempts with sleeps [5, 10], or initial attempt plus three retries with four total CP calls and sleeps [5, 10, 20] before attempts 2-4. In either case, do not sleep after the last attempted request, and update the warning text/test so an exhausted run cannot false-green on wasted terminal backoff.

Secondary scope note: this PR is described as the #2859 prod-deploy helper, but the current diff also changes local-provision/provisioner files for #2851. Those may be valid, but they are outside the stated scope and should either be split or called out explicitly so reviewers do not treat this as prod-auto-deploy.py-only.

fix(deploy): #2859 bounded retry + error surfacing for redeploy-fleet transient 502s ... 0deda38a0c

The production auto-deploy helper hard-failed when CP returned HTTP 502
for the hongming canary redeploy-fleet call. 502/503/504 are typically
transient gateway/upstream flakes (SSM, ECS), so the whole fleet rollout
should not halt on a single unclassified gateway error.

Changes:
- redeploy_scoped() performs an initial attempt plus up to 3 retries for
  HTTP 502/503/504, with delays 5s/10s/20s applied BEFORE each retry.
  The final attempt returns immediately without a misleading terminal
  sleep.
- Each retry warning now includes the endpoint URL and a bounded CP
  error-body detail so operators can see the transient reason.
- _raise_for_redeploy_result() surfaces the CP error body in the
  RuntimeError (uses the same _redeploy_error_detail helper).
- Added pytest coverage for retry-success, retry-exhausted (no terminal
  sleep), no-retry on non-transient 500, warning content, and error-body
  surfacing.

Scope note: this PR is intentionally deploy-helper-only. Any local-
provision #2851 changes were removed and remain in PR #2860.

Fixes #2859

APPROVED on head 0deda38a0c.

Re-reviewed the fixed head against RC #11780:

• Retry semantics are now correct and bounded: total_attempts = 1 + REDEPLOY_MAX_RETRIES, delays [5,10,20] are applied only before attempts 2-4, and exhausted transient failures log retries exhausted without a terminal sleep.
• Intermediate retry warnings now include the redeploy endpoint and a bounded CP error detail, and the tests assert both endpoint/body visibility and corrected no-terminal-sleep behavior.
• Scope is clean: the PR now changes only .gitea/scripts/prod-auto-deploy.py and .gitea/scripts/tests/test_prod_auto_deploy.py; the unrelated #2851 local-provision/provisioner files are gone.
• Exact-head CI is green for required core contexts: CI / all-required, E2E API Smoke Test, Handlers Postgres Integration, and E2E Peer Visibility are present+success. Ops Scripts Tests is also success on this head.

The retry remains capped, non-transient 500s are not retried, and CP failure bodies are surfaced for operator diagnosis.

APPROVE on 0deda38a0c.

Re-verified the #11781 fixes. Retry semantics are now explicit and correct: redeploy_scoped() performs initial + 3 retries (4 total attempts), sleeps [5, 10, 20] only before real follow-up attempts, and the final transient response logs retries exhausted instead of a misleading retrying message. The tests drive the real function via monkeypatched cp_api_json/time.sleep, assert the no-trailing-sleep shape, and cover retry success, exhausted retries, non-transient no-retry, and CP error body surfacing.

Scope drift is also fixed: PR files are only .gitea/scripts/prod-auto-deploy.py and .gitea/scripts/tests/test_prod_auto_deploy.py; the #2851 local-provision/provisioner changes are no longer in this PR. Exact-head required/code CI is green (CI / all-required, Platform Go, E2E API Smoke, Handlers Postgres, Peer Visibility, Local Provision stub). Remaining reds are ceremony gates and the known real-image advisory, not blockers for this helper-only fix.
