ADR-0024 audited as fully implemented. Amend the ADR with a "Phase F
minimal" implementation note (parser.rs retained as the router +
ParseError home) and update the README index line to match.
Reconcile docs/requirements.md against handoffs 10-14: refresh the
test baseline (449 -> 1006), mark U4 (replay) satisfied, correct the
A1 / H1a / H3 progress notes.
Amend handoff-14: §3 flagged items both resolved (ranker kept,
CommandNode.hint_mode removed); §4 rewritten as a concrete next-work
pointer at the reconciled requirements.md.
Concrete specification for the direction in ADR-0023, landed
during the round-6 design pass. Resolves all four rounds of
open design questions: walker as single source of truth,
scannerless terminal vocabulary (~8 building blocks), typed
value slots with content validators, WalkContext for schema-
aware narrowing from day one, WalkOutcome multi-purpose
return, HintMode per-node, ranker as separate layer, static
+ dynamic sub-grammars, aliases as Word annotations,
IdentSource taxonomy, six-phase per-command migration with
chumsky and walker side-by-side during the transition.
Key shifts from ADR-0023's sketch:
- Lexer dissolves entirely. Walker operates on bytes directly.
dsl/lexer.rs, dsl/keyword.rs go away in Phase F.
- Schema-aware parse from day one (not phased). Typed value
slots reject mis-shaped input at parse time with localised
wording. Completion narrows per column type.
- Sub-grammars: static (fn() -> Node) for composition;
dynamic (fn(&WalkContext) -> Node) for schema-dependent
expansion. No global named registry.
- Path-bearing commands: BarePath becomes a routine
non-whitespace terminal. Paths with spaces require quoting
via StringLit (UX simplification, aligns with standard CLI
convention).
- 13-node taxonomy: Word, Punct, Ident, NumberLit, StringLit,
BlobLit, Flag, BarePath, Choice, Seq, Optional, Repeated,
DynamicSubgrammar.
Migration plan: Phase A (walker scaffolding + app-lifecycle
commands), Phase B (DDL without value literals), Phase C
(create table), Phase D (data commands with full schema
awareness -- the design's central claim landing), Phase E
(replay), Phase F (delete chumsky + lexer + legacy parser
modules, simplify catalog). Estimated ~4 sessions total.
Also: rename ADR-0023 from 0023-proposed-unified-grammar-tree.md
to 0023-unified-grammar-tree.md (git mv preserves history)
and update its status to reflect the direction-accepted-but-
superseded-for-execution-detail relationship with ADR-0024.
Index updated.
