Omar Sobh 534331ffbe chore: Tier 4d — hoist tempfile/criterion/half/serde to workspace.dependencies
CI / test (push) Failing after 13s
Details 
Add [workspace.dependencies] to the root Cargo.toml for the four
duplicated-across-many-crates dependencies flagged by the earlier review:
tempfile (7 crates), criterion (6), half (4 — real version skew, clawhdf5-gpu
pinned 2.7 while others used bare 2), and serde (4). Update every consuming
crate to `dep = { workspace = true }`, preserving crate-local `optional =
true` where it already existed. half now resolves uniformly to 2.7.x
workspace-wide instead of two separate semver ranges.

Also fixed clawhdf5-filters/Cargo.toml's stale "rustyhdf5" description
while touching the file (same class of leftover rename as prior fixes).

Not touching rayon/byteorder/clap (no skew found, lower priority).

Omar SobhandClaude Sonnet 5 6b1ea450f5 chore: cleanup pass — remove empty types stub, implement superblock v4, reconcile plan docs 
- Remove clawhdf5-types (empty 1-line stub crate; type defs already live in
  clawhdf5-format). Update workspace Cargo.toml and CLAUDE.md accordingly.
- Implement HDF5 superblock v4 (page-buffer mode) read and write support in
  clawhdf5-format: Superblock::parse_v4, page_size field, v4 serialize
  branch, and FileWriter::with_page_size. This was the one task left
  unimplemented from docs/superpowers/plans/2026-06-29-format-write-extensions.md.
- Reconcile the three docs/superpowers/plans/*.md docs (filter codecs,
  format write extensions, MPI-IO VOL) against actual shipped code: they
  were pre-work plans for d6c4d4f (2026-06-30) committed to git late on
  2026-08-03 with all checkboxes still unchecked. Mark completed tasks done
  and add a status note so they read as historical records, not open work.
- Refresh ROADMAP.md's "What's Next" section against current repo state.

Omar SobhandClaude Sonnet 4.6 d6c4d4f111 feat: implement filter codecs, format write extensions, and MPI-IO VOL 
All three SDD plans fully wired and committed to main:

Filter Codecs (FC):
- FC-1: Implement float E-scale in scaleoffset_decompress (value = minval +
  code * 2^E, negative exponents via cast to i32); add two round-trip tests.
- FC-2: filters_szip.rs — feature-gated SZIP decode via libaec FFI; SZIP
  dispatch arm added to decompress_chunk.
- FC-3: libaec-sys workspace crate with pkg-config probe and aec_buffer_decode
  FFI binding; added to workspace members.

Format Write Extensions (FWE):
- FWE-1: GroupBuilder::add_external_link() API; wired through FinishedGroup
  → GrpFlat → file_writer pass 1/2/3 (OH size, layout cursor, final write);
  external_link_write_roundtrip test.
- FWE-2: data_layout_write.rs — serialize_vds_mappings with length_size param
  and version 0/1 (external vs same-file) selection; declared as pub mod.
- FWE-3: with_virtual_sources empty-mapping guard (Important #9) — empty vec
  is silently ignored; vds_empty_mapping_list test updated to assert non-VDS
  layout results.

MPI-IO VOL Backend (MPI):
- MPI-1/2/3: mpi_vol.rs — MpiVol implementing VirtualObjectLayer; root-read
  + broadcast collective read; gather + root-write collective write; feature-
  gated mpi-io feature; wired into clawhdf5-io lib.rs.
- MPI-4: mpi_io_bench binary (h5bench-equivalent MPI-IO throughput bench).

mpi_vol.rs reviewer fixes:
- Doc-comment updated to accurately describe root-read+broadcast pattern
  (not MPI_File_read_at); MpiVol::expected_capabilities() associated fn
  added so tests can verify capabilities without a live MPI universe;
  rank_and_size_stub_values renamed to no_feature_error_contains_feature_name.

Workspace check: zero warnings, 20 test suites pass.
