ltx-zig v0.1.0

Added

• Allocation-free LTX v3 decoding and canonical encoding for current raw-LZ4
  blocks and the historical upstream frame profile.
• Strict structure, page-index, CRC-64, rolling database, snapshot, and terminal
  verification over bounded caller-owned workspaces.
• Bounded storage-neutral compaction and staged apply orchestration.
• External path-dependency compile and smoke gates plus runnable bounded
  snapshot-apply and SQLite generation-store lifecycle examples.
• A canonical local source-archive smoke gate that extracts with isolated
  caches and runs the archived consumer and examples.
• Optional crash-qualified two-generation SQLite storage with typed read-only
  generation leases and explicit recovery after indeterminate publication.
• Real WAL-mode SQLite A-to-B-to-C qualification for checksummed snapshot and
  incremental publication, including growth, shrink, blocked reset and lease
  paths, late input corruption, exact generation bytes, and semantic queries.
• SQLite-produced A-to-B-to-C process-crash replay at every publication
  durability boundary, plus retained-lease, stale-epoch, and checksum-scanning
  recovery qualification over real database images.
• Pinned Go and Celld interoperability fixtures, mutation and fuzz suites, and
  byte-for-byte Go-oracle compaction checks.
• An immutable real-Litestream v0.5.11 six-transition capture chain with exact
  artifact and restored-image hashes plus final read-only SQLite qualification.
• Outbound compaction qualification against pinned Go bytes and a
  checksum-pinned Litestream v0.5.16 restore over mixed current-L1 and
  legacy-L0 page representations.
• A five-chain deterministic compaction matrix with exact Go output bytes,
  pinned database hashes, staged-apply equivalence, and real-Litestream
  success/expected-rejection coverage of its no-checksum restore boundary.
• Public SQLite store state and adapter-specific failure inspection, with an
  explicit retry/recovery decision contract.
• Exhaustive returned-fault qualification at every SQLite durability boundary
  and synchronized cross-process generation-lease abandonment coverage.
• MIT licensing with the required separate BSD-3-Clause LZ4 and Apache-2.0
  Celld/Litestream attributions.
• A checked resource-budget model with conservative workspace/output formulas,
  reference configurations, and portable formula tests.
• A 17-case encoder/decoder 4 KiB–64 KiB pattern matrix, 1/4/16-input
  compaction scaling, checked/no-checksum staged-apply benchmarks, and a
  correctness-only smoke mode; the focused raw-LZ4 microbenchmark remains
  available separately.

Fixed

• SQLite generation workspace alias failures now report
  Failure.invalid_workspace instead of Failure.invalid_state.

Changed

• The pre-1.0 Zig source API is explicitly allowed to evolve with its
  coordinated consumer; 0.x releases make no source-compatibility promise.
• CI now qualifies Debug and ReleaseSafe behavior on pinned Linux and macOS
  toolchains, public-module compilation across five targets, consumer package
  wiring, the bounded example, and release metadata.
• A pinned, digest-locked act task rehearses the Linux lane without mounting
  the host Docker daemon; hosted Linux and macOS remain authoritative.
• SQLite directory durability barriers are portable across qualified hosts.
• Release metadata validation permits TBD during candidate work but requires
  a real YYYY-MM-DD changelog date before tag qualification.
• CI compiles both benchmark executables and runs resource and benchmark-smoke
  correctness gates without timing thresholds.
