# v0.103.0 full implementation details

**Status: Released.** v0.103.0 makes WAL capture durable at the receipt
boundary and keeps workload control on the existing scheduler contracts.

## Delivered

- Added `pgtrickle.pgt_wal_receipts` plus per-source receipt and acknowledgement
  high-water marks.
- Changed WAL polling to peek, persist, replay, and acknowledge in separate
  transactions so a worker restart can replay committed receipts.
- Re-enabled WAL admission with trigger fallback for unavailable prerequisites,
  transition failures, and repeated decoder errors.
- Added the versioned workload-budget contract, capability manifest entry,
  upgrade migration, install archive, and release gate.

## Verification

The release gate checks metadata, generated SQL, receipt wiring, workload-budget
shape, roadmap status, and capability-manifest freshness. Runtime fault-injection
and benchmark evidence remain the responsibility of the database-backed release
tiers and the weekly performance workflows.
