Specifies the curated per-cell classification (clean / lossy / incompatible) for column type changes, the static transformer matrix (numeric chains, text↔structured types, always-clean stringifications), and the PK / shortid / uniqueness-bearing handling. Replaces the B2/C2 placeholder of "rely on engine STRICT and surface its errors" with a learner-friendly model that: * refuses incompatibles up-front, * refuses lossy conversions by default with a re-run-with- --force-conversion hint, * refines the PK refusal: an inbound-FK PK is only refused when the new type would change the FK target type (so `serial → int` and `shortid → text` on FK-referenced PKs are allowed; `int → text` etc. still refuse), * adds a post-transformation uniqueness check for PK and shortid columns, * uses the pretty-table renderer (ADR-0016) for all diagnostic row lists, * emits a `[client-side] …` note in the success summary whenever the transformer rewrote any cell. `--force-conversion` accepts loss; `--dont-convert` skips the client-side layer entirely; mutually exclusive. Forward-look: a future iteration may add resolution flags (`--default 0`, `--on-incompatible '<value>'`). Also amends ADR-0002 with a new "User-facing posture" section cementing that the database engine choice is an implementation detail and is never named in user-visible strings. Adds a corresponding bullet to CLAUDE.md's working-style rules so every session picks it up. Implementation lands as a follow-up.
