docs: ADR-0048 Phase 1 accepted/implemented + handoff 65

- ADR-0048 status -> Accepted; Phase 1 implemented (commits
  202e25a..fbd219b), with the pre-build and post-implementation /runda
  passes and the 2358-test green state recorded; index entry updated.
- requirements.md: SD1 [x] (whole-row seed + FK/junction, both modes,
  --seed reproducibility with no exceptions), SD2 [/] (core generators /
  determinism done; the set override clause + column-fill are Phase 2),
  A1 14/15 (only hint/H2 remains unregistered).
- Handoff 65: the full seed Phase-1 build, the two /runda passes, where
  the code lives, and Phase-2 / next steps.

 ## Status
 
-**Proposed (2026-06-11).** Design settled with the user across an
-extended fork dialogue (every decision below was escalated and
-user-chosen), then hardened by a `/runda` Devil's-Advocate pass that
-found six blockers — undo integration (D15), replay semantics (D16),
-`set` value quoting (D2), CHECK-constraint handling (D17), a
-phase-ordering bug in the advisory (D13), and auto-show flooding
-(D18) — plus refinements (state-relative reproducibility, compound-FK
-tuple sampling, column-fill constraint rules, the `fake` dependency
-scan). All are folded in below, the three genuine forks among them
-re-escalated and user-resolved. Pending **phased, test-first
-implementation**; this status flips to *Accepted / implemented* once
-that lands.
+**Accepted (2026-06-11); Phase 1 implemented (2026-06-11).** Design
+settled with the user across an extended fork dialogue (every decision
+below was escalated and user-chosen), then hardened by a pre-build
+`/runda` Devil's-Advocate pass that found six blockers — undo
+integration (D15), replay semantics (D16), `set` value quoting (D2),
+CHECK-constraint handling (D17), a phase-ordering bug in the advisory
+(D13), and auto-show flooding (D18) — plus refinements (state-relative
+reproducibility, compound-FK tuple sampling, column-fill constraint
+rules, the `fake` dependency scan), all folded in.
+
+**Phase 1 shipped** test-first across commits `202e25a` (generation
+library + `fake` dependency) → `f1e9484` (command skeleton) →
+`73493fa` (FK sampling) → `9c13501` (uniqueness / junction / IN-CHECK)
+→ `0b3ab3c` (`SeedResult` / preview / advisory / count cap) →
+`e6ff63d` (single-transaction O(N) path) → `fbd219b` (`--seed` flag,
+ambient wiring, and a whole-implementation `/runda` pass). The
+post-implementation `/runda` found eight gaps — FK-sampling
+determinism (now `ORDER BY`), shortid reproducibility (now from the
+seeded RNG, so **D4 holds with no exceptions**), and six untested
+ADR decisions (D5/D15/D16/D17 + atomicity + zero-count), all closed.
+**2358 tests pass / 0 fail / 0 skip; clippy clean.**
+
+**Implemented in Phase 1:** the whole-row `seed <table> [count]
+[--seed <n>]` form and every D1–D18 decision *except* the two
+deferred-to-Phase-2 surfaces below. **Deferred to Phase 2** (designed
+here, not yet built): the **`set` override clause** (D2) and the
+**`<table>.<column>` column-fill** form (D1 form 2). Further SD2
+increments (custom user generators, NULL injection, multi-locale,
+recursive parent auto-seed) remain out of scope (see Out of scope).
 
 Closes `requirements.md` **SD1** and delivers the core of **SD2**
-(per-type generators, determinism, the override surface). It also
-closes one of the two remaining gaps in **A1** ("all canonical
+(per-type generators, determinism, the `fake`-backed catalogue). It
+also closes one of the two remaining gaps in **A1** ("all canonical
 app-level commands") — `seed`; the other, `hint` (**H2**), is
 separate.
