Beava v0.0.6

v0.0.5 — durability + correctness fixes, CI coverage tooling

Critical
- force=True schema replacement now survives crash recovery (#139). WAL
  replay reproduces the force-removal cascade and pre-replace events no
  longer credit post-replace aggregations. Adds
  registered_at_version filtering on replay via a new
  apply_event_to_aggregations_replay sibling.

High
- Admin /registry endpoint refreshes on every successful register
  (#136). Was pinned at 0/0; now reflects the live registry version +
  node count via a SharedRegistrySnapshot Arc threaded through
  AppState.
- select / drop / rename schema narrowing is enforced at register-time
  (#138). Downstream aggregations on a removed field now raise
  RegistrationError. Catches the SDK chain-prefix flattening case
  where the agg derivation's own ops include the narrowing op.

Medium
- TCP /get feature_not_found returns the same structured envelope as
  HTTP (#135). Was {"code":"unsupported"} — now
  {"error":{"code":"internal_error","reason":"feature_not_found: ..."}}.
- Expression where-predicate nesting depth rejected at parse time
  instead of silently returning Null (#133).

CI / quality
- Informational coverage reports for Rust (cargo-llvm-cov) and Python
  (pytest-cov) on every PR (#141). No gates, no third-party uploads —
  visibility only.
- Coverage lifts (#142): Python 70% -> 78%; beava/test/*,
  beava/cli/__init__.py, beava/_col.py, beava/_wire.py all at 100%.
  Rust workspace 84.41% -> 84.44%; recovery.rs 67.70% -> 70.04%.
- Loosened sketch recovery assertions to tolerate t-digest / entropy
  float drift across snapshot+WAL replay (#140).

SDK arg validation
- Rejected multi-upstream @bv.event def at decoration time with a sharp
  TypeError (#131).
- TcpTransport.send_push now raises on OP_ERROR_RESPONSE instead of
  returning the error envelope (#130).
- Tightened operator arg validation: NaN bucket, empty field, sigma,
  q=None (#129).

release: v0.0.4 — operator bug fixes + decision-feed visual cleanup

* WindowedOp::update_at honours the dispatcher's pre_val
  (fixes mean+window→Null and top_k binding to the wrong field).
* EventTypeMixState::update_at honours pre_val (same bug class).
* SDK ~bv.col(x) emits (not x) instead of !(x).
* Home decision feed runs synthetic-only with passive decisions
  rendered green; never shows 3-of-a-kind in a row.

33 regression tests across Rust + Python lock the bug class down.
See CHANGELOG.md for the full breakdown.

Beava v0.0.3

Syncs workspace Cargo version with PyPI package version so `beava --version`
reports the same string as `pip show beava`. Source-identical to v0.0.2.

Beava v0.0.2

Enables Homebrew install path via multi-platform binary tarballs attached
to the GH Release. Syncs Rust crate version with Python package version.
See CHANGELOG.md.

Beava v0.0.1 — first PyPI publish

Same surface as v0.0.0; version bump exists so the inaugural Trusted-Publisher
OIDC flow can claim the `beava` project name on PyPI. See CHANGELOG.md.
