DSI Product 0.2.1

• Deployment doctor — dsi doctor, a read-only readiness check you run first. "Ready for audits" means installation readiness only.
• Installation validation — dsi validate-install runs a real, domain-consistent audit end to end (audit → evidence card → regression).
• Readiness endpoint — GET /ready (503 when not ready); an enriched GET /version.
• Regression Audit — first formal release: an instrument-relative comparison of paired outputs, with instrument-limited verdicts and provenance.
• Clean-install verification — the built package is installed in an isolated environment and checked to run from documentation alone.
• Consolidated documentation — getting-started, deployment profiles, and security & operations guidance.

• Embedded decision phrasing. Indirect questions such as "I don't know if I should stay or look elsewhere" are now recognised as decisions and audited against the full applicable set, matching their direct form "Should I stay or look elsewhere?" — rather than being reduced to a single clarification path.
• Install validation consistency. The end-to-end check now audits with a prompt matched to the selected domain, rather than pairing an arbitrary prompt with an arbitrary domain.

• D-CTX-1 did not change classifier or scorer logic — the fix changed how the applicable set is constructed, not the matching or the scoring. Separately, v0.2.1 ships classifier expected-map-lexical-precision-v3, which rebases audit identities: audit ids from v0.2.0 bundles do not carry forward.
• Public output schema unchanged.
• The frozen 54-prompt compatibility replay showed zero denominator or coverage changes.
