fix(prism): keep BYOK seal alive for full train wall - #146
Merged
Conversation
Raise payer vault TTL to ≥36h (train+eval+skew floor) and re-seal on measure start plus heartbeats so full-budget runs survive control-plane restarts without losing the miner Lium key at harvest/resume.
📝 WalkthroughWalkthroughThe change adds configurable minimum TTL handling for sealed payer vaults, renews seals during Lium orchestration and log monitoring, updates recovery documentation, and expands retry authentication guidance. ChangesPayer vault resealing

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Align the retry guidance with the implemented credential paths.
post_retry does not read X-Miner-Hotkey or a body hotkey. It reuses row.miner_hotkey from storage. It also accepts a sealed payer-vault entry instead of requiring X-Lium-Api-Key. Update this message to describe the stored miner hotkey and the X-Lium-Api-Key or sealed-vault alternatives, or add validation for the documented inputs.
Proposed wording
- "status={} — /retry only accepts failed rows; for miner infra retry send X-Lium-Api-Key (and the usual X-Miner-Hotkey / body hotkey). Admin Bearer is for operator retries of non-infra failures",
+ "status={} — /retry only accepts failed rows; miner infra retry requires X-Lium-Api-Key or a sealed payer-vault entry. The stored miner hotkey is reused. Admin Bearer is for operator retries of non-infra failures",📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Preserve and handle sealed-vault refresh failures.
refresh returns false for both a missing key and a failed sealed::persist call. The measure path and heartbeat path discard that result. A failed seal write can therefore leave an active paid job with only an in-memory credential. A control-plane restart then cannot reattach, harvest, or terminate the pod.
