Document the regression-hardening work from this session:
- ADR-0008 Amendment 1 — Tier 4 realized: the portable-pty + vt100 harness,
expectrl dropped, serial/fail-fast design, the four flows, sidebar-region
reads, command pacing (issue #39), CI default-target (advances TT5).
- ADR-0057 (new) — NFR verification strategy: contrast + ΔE2000 gates
(NFR-5/7), startup/RSS measured (NFR-1/3: release ~29 ms / ~10 MB),
NFR-2 by architecture, NFR-4/6 reviewer note. Records the two shipped
light-theme contrast defects this work caught and fixed.
- requirements.md: TT4 [~]->[x], TT5 [/] (only a Windows exec runner left),
NFR-1/2/3/5/7 ->[x], NFR-4/6 ->[/], each with evidence.
- CHANGELOG.md (new): Keep a Changelog + SemVer, [Unreleased] + [0.2.0].
- README ADR index updated; handoff-76; the working plan.
Docs-only (CI gate skips via paths-ignore).
Captures up-front design decisions for RDBMS Playground:
stack (Rust + Ratatui + SQLite), input modes, project file
format, type vocabulary, undo snapshots and replay log,
sharing/export, and testing approach. ADR-0000 establishes
the ADR practice itself and mandates index upkeep alongside
any ADR change.
