# v0.105.x: Qualification, longevity, and 1.0 candidates

> **Status:** Planned
> **Scope:** Variable
> **User promise:** *"The documented build has passed the documented release conditions."*
> **Blocked by:** [v0.104.0](v0.104.0.md)

## Theme

Qualify the frozen v0.104.0 contracts on the exact artifacts proposed for 1.0.
This series accepts release-blocking fixes and removes risk. It adds no SQL
features or capabilities.

This work reuses the v0.98.1 qualification structure and adds the full
72-hour soak. Releases v0.99.0 through v0.104.0 change the implementation and
public contracts, so v0.98.1 evidence is historical and cannot qualify a v1.0
candidate.

## Allowed work

- correctness and security fixes
- compatibility, documentation, and package fixes
- missing tests and clearer diagnostics
- performance regression fixes
- removal or narrowing of unstable optimizations
- release automation and retained evidence

## Qualification work

- Freeze a v0.105 qualification contract before the first candidate. Use the
  v0.98 contract schema for exact suite commands, artifacts, observation
  windows, numeric slope and absolute-growth limits, and performance budgets.
- Run the exact oracle, capture fault matrix, Graph V1 and Delta V1 conformance,
  real binary upgrades and recreation paths, a 72-hour mixed-workload soak,
  package maintenance tests, and performance budgets.
- Bind each result to its source commit, artifact digest, PostgreSQL version,
  suite version, workload, and retained logs.
- Keep a longer-running deployment across candidate builds to detect cumulative
  state growth and repeated recovery loops.
- Have independent operators run the install, diagnose, alter, upgrade,
  restore, and resnapshot procedures.

## Exit criteria

- [ ] No correctness or security blocker remains in the supported product.
- [ ] Every required result names the candidate commit and shipped artifact
      digest.
- [ ] The upgrade manifest covers the accepted post-v0.98 path and classifies
      every recreation boundary.
- [ ] Memory, catalog, buffer, output-log, and disk use remain within every
      numeric slope and absolute-growth limit over the frozen observation
      windows.
- [ ] Supported packages maintain real data through the advertised upgrade
      procedure.
- [ ] Every remaining limitation has a stable diagnostic and supported
      response.

Publish `v1.0.0-rc.1` only after these gates pass. Repeat the candidate series
as needed. A material capture, finalization, or recovery change invalidates the
related evidence and requires a new qualification run.
