The wave-2 facade skeleton and routing (tasks/store-construction.md):
the public surface consumers program against, with the ops methods
still to land against it in store-read-paths/gc-protocol/store-put-paths.
- src/store.rs — the public `Store` type (engine-blind, ADR-007/008/
010) over crate-internal tier enums (`KvEngine`{mem}, `LargeEngine`{
local}): the engine-representation design point decided as concrete
+ enum dispatch, generic rejected (pub(crate) engines, no dyn);
the three constructor modes as named constructors — `mem_only`,
`kv_only_mem`, `dual_tier_mem_local` (the ADR-012 §6.3
dispatch-coverage shape) — with `StoreMode` introspection; the
write-side routing seam (`tier_for`), the read-side fall-through
order (`kv()` then `large()`, ADR-012 §6.1), and the `GcHome`
GC-state field; the ADR-012 §3 fleet declaration ruled deferred to
the engine waves (nothing fleet-valid is constructible yet)
- src/dispatch.rs — the pure routing function (`route`, at-or-below
→ kv), `DEFAULT_DISPATCH_THRESHOLD` (128 KiB) exported at the
crate root, boundary-value unit tests (exactly-at-threshold,
degenerate tunings, purity)
- src/gc.rs — `GcHome`: the store-instance GC-state home the
gc-protocol task fills (in-process; fleet state stays on the
engine-state seam per ADR-010 §2/ADR-012 §4)
- tests/conformance — the wave-2 binding made as anticipated: the
factory's `Store` associated type collapsed into the concrete
`alkblobs::Store` (`open` vends it directly), recorded in
factory.rs + README; the wave-1 mock probe retired, replaced by
mem-gated binding demo factories (binding.rs) over both
constructible shapes
Verification: `cargo test` (default), `cargo test --features mem`,
`cargo test --all-features` green (41/53/53 unit + conformance
targets green in all three shapes); `cargo clippy --all-targets
-- -D warnings` green in all three feature shapes; `cargo fmt
--check` green; `cargo doc --no-deps` adds no warnings beyond the
pre-existing private-intra-doc-links class.
- tests/conformance/README.md: the convention doc — row naming (property-
stated names, engine dimension is the column), the Contract stamp:
format (the alkstore ADR-017 §4.2 convention adapted), the one-
normative-owner-per-property rule, the factory contract (fresh
isolated instance per open, idempotent teardown, safe over an
abandoned instance), the SKIP posture (SQL-attached columns skip
cleanly server-less; acceptance requires green against the server),
the invariant backlog (the seven store-api.md §Invariants registered
as the rows-to-grow table with pinning citations), and the mem-first
column plan (mem is the contract-reference engine, ADR-011 §2)
- harness skeleton, compile-able with zero rows: StoreFactory (fresh
+ isolated + idempotent-teardown contract; the Store associated type
is wave 2's binding point for the facade type), stamp.rs (the
marker + convention anchor), backlog.rs (in-code registry with a
traceability gate asserting INV-1..7 mirror §Invariants in order)
- no engine-specific code; no dependencies added
Verification: cargo test (33 passed across lib + 3 targets),
cargo clippy --all-targets -- -D warnings, cargo fmt --check
