215. Vitte Platform Maturity Baseline

Objective: define the minimum evidence required to claim credible platform maturity.

Date: 2026-05-24

Maturity Conditions

Each condition below must have objective evidence.

  1. Progressively self-hostable compile
  2. Evidence: staged bootstrap artifacts, reproducible stage progression checks, documented trust root.
  1. Verifiable pipeline
  2. Evidence: deterministic step outputs, pipeline tests per stage, gate reports.
  1. Reliable diagnostics
  2. Evidence: stable code catalog, snapshot coverage, deterministic output under strict mode.
  1. Reproducible backend
  2. Evidence: same-source/same-toolchain identical outputs for covered targets.
  1. Stable runtime
  2. Evidence: runtime smoke + stress + fault-path tests and regression tracking.
  1. Maintainable stdlib
  2. Evidence: ownership map, API contracts, sync docs/tests, deprecation tags.
  1. Stable IDE tooling
  2. Evidence: LSP smoke checks, completion/hover/diag contracts and snapshots.
  1. Reproducible package management
  2. Evidence: lockfile contract, dependency resolution determinism, offline/install replay checks.
  1. Robust incremental compilation
  2. Evidence: cache hit/miss reports, invalidation tests, no stale-result regressions.
  1. Validated deterministic builds
  2. Evidence: deterministic build gates in CI + release validation report.
  1. Active chaos testing
  2. Evidence: periodic fault-injection runs with tracked and fixed outcomes.
  1. Active fuzzing
  2. Evidence: continuous parser/frontend fuzz runs and corpus growth tracking.
  1. Active stress testing
  2. Evidence: sustained workload tests with thresholds and trend history.
  1. Documented architecture
  2. Evidence: architecture pages aligned with source and checked for drift.
  1. Defined technical governance
  2. Evidence: approved governance docs and review cadence in operation.
  1. Possible long-term maintenance
  2. Evidence: windows support, deprecation and migration policy, SLO adherence triage.

Baseline Scorecard

Status section:

  • red: no reliable evidence or repeated regressions.
  • amber: partial evidence; gaps block platform claim.
  • green: evidence automated and passing in release gates.

A release can be labeled "platform-credible baseline met" only when all 16 conditions are green or when temporary amber exceptions are explicitly approved in release notes with deadlines.
