copy_to_path returned Ok(()) without flushing, so the copy was not guaranteed on disk. Flush after the copy, matching create() and flush() in the same file. Also add a round-trip test for copy_to_path, which had none.
* Benches: use SmallRng instead of ChaCha12-based generators
All benchmarks used StdRng or rand::rng() (ThreadRng), both backed by the
ChaCha12 block cipher in rand 0.10. Benchmarks do not need crypto-strength
randomness, and several draw random values inside the timed closure, so
cipher work was included in the measurement itself.
Switch every bench target to SmallRng (Xoshiro256++), and key the HNSW
graph cache and sparse index cache by RNG algorithm so stale caches built
from the old generator are not reused against newly generated vectors.

* Benches: replace free-function rand::random with local SmallRng
Addresses review: rand::random draws from the thread RNG (ChaCha12),
including inside the timed loop of the pq score benchmark.

Overlapping closed WAL segments indicate on-disk inconsistency (e.g. a
partially-applied manual truncation or a file copy accident). The
contiguity check already returns InvalidData for gaps between segments;
the overlap branch was hitting unimplemented!(), crashing the process
on any WAL that has overlapping closed files.
Replace the unimplemented!() with an InvalidData error using the same
pattern as the gap branch. This lets callers handle corrupt-segment
state rather than receiving a panic.
Add a regression test that seeds a WAL with overlapping closed-* files
and asserts that with_options() returns ErrorKind::InvalidData.
`dir.try_lock()` resolves to the inherent `fs_err`/`std` `File::try_lock`,
which Rust's stdlib gates to a fixed target list that excludes
`target_os = "android"` (1.89+). On Android it returns
`ErrorKind::Unsupported` ("try_lock() not supported"), so opening a WAL —
and thus creating/loading a shard via qdrant-edge — fails.
Dispatch explicitly to `fs4::FileExt::try_lock` on the underlying
`std::fs::File`, which issues a direct `flock(LOCK_EX | LOCK_NB)` syscall
that Android supports. This restores the pre-#8770 behavior. UFCS is needed
because fs4's trait method collides by name with the inherent one (which
otherwise wins method resolution).

* feat(edge): expose WAL options via EdgeShard::load_with_wal_options
Adds a sibling method to EdgeShard::load that accepts custom
WalOptions, alongside the existing load() which keeps using
default_wal_options().
Motivation: embedded/mobile deployments (e.g. Flutter plugins on
iOS/Android) need much smaller WAL segments than the 32 MiB default —
typically 4 MiB. On filesystems with sparse files (APFS/ext4/F2FS)
the physical footprint is small, but the visible/reported size is
the full segment capacity, which is surfaced by iCloud backup, OS
size pickers, etc.
Changes:
* New EdgeShard::load_with_wal_options(path, config, wal_options).
* EdgeShard::load delegates to it with default_wal_options() — no
behavior change for existing callers.
* ensure_dirs_and_open_wal now takes WalOptions explicitly; called
from both EdgeShard::new (with default) and load_with_wal_options.
* WalOptions re-exported from edge crate root.
* Two regression tests in lib/edge/tests/wal_options.rs.
WAL options are intentionally a runtime parameter, not part of
EdgeConfig (which is persisted to edge_config.json) — different
processes may legitimately open the same shard with different WAL
options.
* test(edge): verify mismatching WAL options on reload preserve data
Addresses upstream review feedback (qdrant/qdrant#9067): demonstrate
that reloading an existing shard with WAL options different from the
ones it was created with is safe and preserves all previously written
points.
Two new tests in lib/edge/tests/wal_options.rs:
* reload_with_smaller_wal_capacity_after_upsert:
create shard with default 32 MiB WAL -> upsert point 42 ->
drop -> reload with 4 MiB WAL options -> point 42 still readable ->
upsert point 43 under smaller WAL -> count == 2.
* reload_with_larger_wal_capacity_after_upsert (symmetric):
create -> reload with 4 MiB -> upsert point 100 -> drop ->
reload with default 32 MiB -> point 100 readable -> upsert
point 101 -> count == 2.
Both pass. The WAL crate does not validate segment_capacity on
reload — existing segments on disk keep their original size,
subsequent appends honor the runtime options. This confirms the
PR description's claim that WalOptions is a runtime hint, not
persisted shard state.
* style(edge): cargo fmt for wal_options.rs mismatch tests
* refactor(edge): replace load_with_wal_options with builder-based options
Addresses upstream feedback (timvisee, generall): the sibling
constructor pattern doesn't scale as runtime configurability grows.
Replaces `EdgeShard::load_with_wal_options(path, config, wal_options)`
with `EdgeShard::load_with_options(path, config, EdgeShardOptions)`,
where `EdgeShardOptions` is a builder-style runtime-options struct.
* `EdgeShardOptions::new().with_wal_options(opts)` is the equivalent
of the old call.
* Adding new runtime options later (e.g. wal flush interval, initial
indexing threshold) is now an additive change — new builder method
on `EdgeShardOptions`, no new constructor variant on `EdgeShard`.
* `EdgeShardOptions` is intentionally not persisted (no
Serialize/Deserialize). The reload-mismatch tests above confirm
that WAL options are a runtime hint, not shard identity, so they
don't belong in `EdgeConfig` (which is persisted to
`edge_config.json`).
* `EdgeShard::load(path, config)` unchanged for existing callers —
delegates to `load_with_options(..., EdgeShardOptions::default())`.
Tests in `lib/edge/tests/wal_options.rs` migrated to the new shape;
all four still pass:
test load_with_options_accepts_custom_wal_capacity ... ok
test load_still_works_with_default_wal_options ... ok
test reload_with_smaller_wal_capacity_after_upsert ... ok
test reload_with_larger_wal_capacity_after_upsert ... ok
* refactor(edge): add fluent builders; move wal_options into EdgeConfig
Replaces the EdgeShardOptions side-channel with a single EdgeConfig that
carries wal_options inline, and introduces fluent builders for the three
user-facing config types.
* WalOptions now derives Clone/PartialEq/Eq/Serialize/Deserialize so it
can live inside EdgeConfig and round-trip through edge_config.json.
* EdgeConfig.wal_options (Option<WalOptions>) replaces EdgeShardOptions.
EdgeShard::load_with_options is folded into EdgeShard::load; both new
and load drive the WAL from config.wal_options.unwrap_or_default().
* New builders/ module hosts EdgeConfigBuilder, EdgeVectorParamsBuilder,
and EdgeSparseVectorParamsBuilder. Each builder has explicit per-field
storage and constructs its target via an exhaustive struct literal in
build(), so adding a field to the target forces a compile error in the
builder.
* publish example switched to the new builder API.

Windows CI takes ~28min vs ~18min on Linux, with some individual tests
running 10-50x slower due to Windows filesystem IO overhead. Since we
only need functional compatibility on Windows (not performance testing),
reduce iteration counts for the worst offenders:
- WAL quickcheck: 10 → 3 iterations (saves ~350s)
- Consensus manager proptests: 256 → 10 cases (saves ~100s)
- Deferred point tests: reduce loop combinations (saves ~250s)
- Gridstore test_behave_like_hashmap: 50k → 10k operations (saves ~200s)

Adapt to breaking changes in fs4 1.0.0:
- `fs4::fs_std::FileExt` flattened to `fs4::FileExt` (segment.rs)
- Removed `fs4::FileExt` import from lib.rs — with Rust 1.89+
`File::try_lock()` is stabilized in std, so the fs4 trait is no
longer needed for exclusive locking
- `try_lock_exclusive()` → `try_lock()` via `fs_err::File` wrapper
with return type `Result<(), TryLockError>` (WouldBlock on contention)
- Removed `lock_contended_error()` — use `ErrorKind::WouldBlock`
On Windows, fs4 1.0.0 skips set_len inside allocate() when the
cluster-aligned allocation already covers the requested size. Add
explicit set_len calls after allocate() so the mmap has the correct
file extent.
The `fs4::available_space()` function used in shard/optimize.rs and
collection/disk_usage_watcher.rs is unchanged in 1.0.0.

Reduce test parameters across 5 areas to cut test runtime without
sacrificing coverage:
1. HNSW PQ tests: lower vector dimensionality from 131 to 64 for product
quantization variants, cutting PQ codebook training time (~31s -> ~8s)
2. HNSW index build: use 2 threads instead of 1 for index construction;
the tests only check accuracy above a threshold so determinism is not
required
3. Search attempts: reduce from 10 to 5 query vectors per test
4. Rescoring: skip the expensive re-upsert-all-as-zeros rescoring check
for PQ tests (already covered by scalar quantization variants)
5. Near-miss speedups:
- WAL: reduce QuickCheck iterations from 100 to 50
- Gridstore: halve operation counts, drop 64-byte block size case,
reduce proptest cases for gap search
- Continuous snapshot: reduce timeout from 20s to 10s
