fix(collector): bound Polymarket verify below timer

[proerror77]

Change

Keep Polymarket OSS verification inside the five-minute timer interval: retry 404/NoSuchKey up to 40 times at four-second intervals and cap the entire readback phase at 240 seconds. This retains coverage of the observed approximately 150-second visibility lag without allowing one run to overlap the next timer firing.

Validation

• git diff --check
• cargo test -p hft-collector --features collector-binance --locked polymarket_upload::tests:: (93 passed, 2 benchmark tests ignored)
• cargo clippy -p hft-collector --features collector-binance --locked --lib -- -D warnings

Runtime impact and rollback

Changes uploader readback timing only; non-404/configuration errors remain fail-fast and _SUCCESS publication ordering is unchanged. Roll back the commit to restore the 600-second budget and 30x20-second curve.

Summary by CodeRabbit

• Bug Fixes

  • Improved reliability when reading back uploaded data by refining retry timing and recovery behavior.
  • Added safeguards to ensure retries operate within a predictable time window, reducing prolonged waits during failures.

• Tests

  • Added coverage to verify that retry handling provides sufficient recovery time while completing within a reasonable limit.

📝 Walkthrough

Walkthrough

The OSS readback retry configuration now uses a 240-second budget, 40 download attempts, and a configurable four-second production delay. A regression test verifies the retry window remains between 150 seconds and five minutes.

OSS readback retry configuration

Layer / File(s)	Summary
Configure and validate the retry window rust_hft/tools/collector/src/polymarket_upload.rs	The readback budget is 240 seconds with 40 attempts and a four-second retry delay. Production derives the delay from the seconds constant, while tests retain a one-millisecond delay. A regression test checks the configured timing bounds.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟡 Moderate · up to 67a0b

The change may cause valid uploads to fail when both the data and completion marker become visible slowly, because they share the same 240-second readback window. Clarify the budget allocation and add coverage for both phases before merging; the retry-bound assertion should also be strengthened.

- Around line 3541-3550: Add an assertion in
remote_readback_retry_window_fits_between_visibility_lag_and_timer verifying
that the computed backoff is strictly less than OSS_READBACK_MAX_WALL_CLOCK,
while preserving the existing lower-bound and wall-clock assertions.
- Around line 74-81: Update the publication verification flow using
OSS_READBACK_MAX_WALL_CLOCK and OSS_VERIFY_DOWNLOAD_ATTEMPTS so the 240-second
retry budget is explicitly shared across data/manifest and _SUCCESS readback
rather than reset per artifact. Ensure both phases can consume the intended
aggregate budget without premature failure, and add a regression test that
delays both readback phases before confirming successful verification.

Re: the open review threads (codex P2s + CodeRabbit):

1. Attempts curve vs wall clock (40×4s=156s of 240s): intentional tradeoff. The observed worst-case object-visibility lag on this endpoint is ~150s (2026-08-01, 109MiB multipart), so 156s of sampling covers the observed window. If a rarer 156-240s lag occurs, the oneshot fails, the source spool is retained, and the next 5-min timer tick re-attempts the upload — failure mode is a bounded retry, not data loss, and each run still terminates well under the 5-min timer cadence (the actual bug being fixed: 600s budgets overlapping the timer and pinning ~85% CPU).

2. _SUCCESS visibility window / marker PUT budget accounting: valid structural points (shared 240s budget is computed before the marker PUT and not re-charged). The marker is a tiny object — its PUT and readback are typically seconds; the 300s oss_timeout is a cap, not the expectation. We accept the residual tail risk (worst-case overrun → oneshot failure → next-tick retry with retained spool) to keep this hotfix minimal. If production shows marker-lag failures, the follow-up is to recompute the deadline after the PUT and/or split the budget — deliberately out of scope here.

Resolving the threads to unblock the merge; the follow-ups above are acknowledged.
