These libraries are all general-purpose (cyber-threat intel,
inter-partition messaging, Linux remoteproc, CRC-32C) but their
synopses/docstrings named SpaceOS as a specific consumer. Reword to
describe what each library does on its own terms.

Follow up to the module rename: update the remaining callers that
still referenced [Err] (library [claude.ml{,i}], [client.ml], the test
driver [test.ml]), and fix one stray [^ e] string concatenation in
hermest's CLI that needed [Json.Error.to_string e] now that
[Json.of_string] yields a structured error.

Warning 69 (unused-field, mutable-never-assigned). Four independent
record fields were flagged as mutable but the code only mutates their
referents in place, never rebinds the record slot itself:

- ocaml-wal/lib/wal.ml: [t.file] (the Eio file resource; methods call
Eio.File.pwrite_all etc., the slot is set once at open time).
- ocaml-block/lib/block.ml: [Memory.state.data] (the backing bytes,
written via Bytes.blit_string; [Bytes.t] is already mutable).
- ocaml-sse/lib/sse.ml: [Parser.t.data_buf] (a Buffer.t, written via
Buffer.add_*; the slot never changes).
- ocaml-zephyr/lib/zephyr.ml: drop [mode : Read | Write] entirely —
set at open-time, read nowhere. The open_read / open_write
constructors already distinguish the two call shapes, so mode
tracking was redundant.

Previously the eight git-x subcommands sat flat at top level (split,
check, fix, verify, filter-paths, split-commit, drop-commit, reword),
with 'split' ambiguous between the subtree split and the per-directory
commit split.

Regrouped into two namespaces that mirror the object they act on:

git-x tree
split (was: git-x split)
add (new — inject a standalone history under a prefix)
drop (was: git-x filter-paths)
check (was: git-x check)
fix (was: git-x fix)
verify (was: git-x verify)

git-x commit
split (was: git-x split-commit)
drop (was: git-x drop-commit)
reword (was: git-x reword)

Each subcommand lives in cmd_<group>_<verb>.{ml,mli}; cmd_tree.ml and
cmd_commit.ml are the Cmd.group wrappers. git_x.ml registers just the
two groups.

'tree add' is a thin wrapper over Git.Subtree.add, which already
existed in the library but had no CLI exposure. It accepts a ref (e.g.
FETCH_HEAD after 'git fetch URL REF') and a --prefix, then builds a
subtree-merge commit with the current user's git config identity.

Log source names are updated to match (git-x.tree.split,
git-x.tree.fix). The cram test under test/cram/tree_split.t is
updated to use the new 'git-x tree split' invocation throughout.

Wire_3d now generates ExternalTypedefs.h, ExternalAPI.h, Wrapper, and
Fields files for schemas using WireCtx. Bitfield padding fixed so .3d
structs match OCaml codec wire_size. Test.c passes NULL for WIRECTX
and links per-schema Field stubs. File naming matches EverParse output.

Also: gitignore EverParse intermediates (.fst, .krml, .rsp, Makefile)
and remove the previously-tracked ones from ocaml-fsr.

Wire_3d now generates ExternalTypedefs.h, ExternalAPI.h, Wrapper,
and Fields files for schemas using WireCtx. Bitfield padding is
fixed so .3d structs match the OCaml codec wire_size. Test.c passes
NULL for the WIRECTX parameter and links per-schema Field stubs.

Affected: ax25, cfdp, fsr, ltp, mbr, pid1, pus, rpmsg, sdls,
spacefibre, squashfs, tcpcl, udpcl, spacewire, and others via @gen.

Generate .opam.template files with x-quality-* fields based on
detected package features:
- x-quality-build: has lib/ with .ml files
- x-quality-test: has test/ with .ml files
- x-quality-fuzz: has fuzz/ with .ml files
- x-quality-interop: has test/interop/ directory
- x-quality-cram: has test/*.t/ directories

These fields are picked up by dune's opam generation and will be
checked by merlint E910 for consistency.

Also: add fmt dep to ocaml-sse/lib/dune (Fmt.pf used without dep).

monopam quality — scans packages for quality features, caches by
git commit hash. 166 packages: build=163, test=162, fuzz=94,
interop=39, doc=42.

Standard vocabulary based on crates.io categories, erratique/opam
conventions, and monorepo domain coverage:

Org: org:blacksun
Domain: aerospace, codec, crypto, network, storage, git, merkle
Purpose: cli, test, bench, format, log, system
Protocol: ccsds, uslp, cop1, sdls, sle, atproto, tls, http, json, binary
Cross-cutting: eio, simulation, math, compression

Tags placed in dune-project (package ...) stanzas via (tags ...).
Propagated to .opam files by dune's opam generation.

Creates c/gen.ml + c/dune + generated .3d files for every package
that defines Wire codecs. Each gen.ml calls Wire_3d.main to project
the OCaml Wire codec definition to EverParse 3D format.

Packages: FSR, PUS, GPT, MBR, PID1, LTP, TCPCL (8 codecs), UDPCL,
AX.25, CFDP (3 fixed-size codecs), SDLS (EP header + MC status),
SpaceWire, RPMsg, SquashFS (5 codecs), SpaceFibre.

Codecs with Wire.Param.input (variable-size) are excluded from 3D
generation: CFDP header/eof/metadata/keep-alive, SDLS security
header/trailer, PUS tm_header/hk_param.

Proximity-1 and space-wire excluded: proximity-1 has only variable-
size codecs, space-wire has its own C generation approach.

Fixes E900 (17→2) and E905 (remaining MBR Partition.struct_).

- Update .ocamlformat to 0.29.0 across all 591 files
- csvt: reuse single Buffer.t for field reads (no alloc per field)
- sexpt: Obj members decoded from stream into Dict, typed Variant GADT
- Reformat all source files for 0.29.0

Migrate all consumers to the new wire API:
- wire.c library → wire.3d (Wire_c → Wire_3d)
- Wire.struct_/module_ → Wire.Everparse.struct_/module_
- Wire.Codec: record/|+/seal → Codec.v with Field.v and $
- Wire.bf_uint* → Wire.U8/U16/U16be/U32/U32be
- Wire.UInt32 → Wire.Private.UInt32
- Wire.cases → Wire.lookup, Wire.map now uses labeled args
- Wire.Codec.decode now returns result
- Add wire pin to root.opam.template

import used List.find_opt on raw map pairs, so a duplicate
"version" or "entries" key would shadow later occurrences.
Now checks for byte-equal duplicate keys before field extraction,
consistent with the receipt parser's cbor_check_unique_keys.

Ensure all 67 fuzz/dune files include gen_corpus.exe in the (alias fuzz)
rule deps for AFL corpus generation. Adds both missing runtest and fuzz
rules to ocaml-cose which had neither.

Fix invalid odoc markup in 54 files: convert {\!Module} to {!Module}
in fuzz .mli files, replace inline {v ... v} with [...] code spans,
fix "paragraph should begin on its own line" warnings, escape bare
brackets, and resolve ambiguous docstring placement (warning 50).

- Remove vendored crowbar/ directory
- Replace all Crowbar references with Alcobar across 176 .ml files
- Update all fuzz dune files: crowbar → alcobar in libraries
- Remove 77 gen_corpus.ml files (alcobar handles corpus internally)
- Update dune-project files: crowbar → alcobar in dependencies
- Update merlint rules (e705, e726): Crowbar → Alcobar in checks,
docs, and examples
- Update merlint generated docs (index.html)

428 files changed, ~1200 lines removed net.

Replace Printf.sprintf with Fmt.str and Printf.printf with Fmt.pr
across requests, retry, and rpmsg test files.

Add pp pretty-printer for Error.t. Rename create_ept_ioctl to
ept_ioctl in rpmsg. Skip find_rel rename as it collides with the
rel field accessor.

Rename create/make to v in rpmsg, error, proxy, auth, version, and
other modules. Fix doc style issues in error.mli, requests.mli, and
expect_continue.mli. Update all callers.

Strip get_/make_/find_/create_ from 138 function definitions and all
call sites across ocaml-pds, ocaml-pid1, ocaml-precommit,
ocaml-publicsuffix, ocaml-qemu, ocaml-requests, ocaml-retry, and
ocaml-rpmsg. Use Module.v for constructors per the E331 convention.

Rename _get to get_entry in h2_hpack.ml and _iow to iow in rpmsg.ml
and test_wire.ml since these bindings are actually used.

- Validate HTTP-date time components (reject second=60) per RFC 9110
- Fix tty table truncation test to explicitly set overflow to Truncate
- Correct tty table.mli overflow default documentation
- Initialize crypto RNG in streaming-aead fuzz runner
- Add docstrings to test module mli files across requests and rpmsg

These are general-purpose OCaml libraries; their READMEs should describe
what the library does, not which product uses it.

Add missing periods to doc comments, fix [name] format mismatches,
and add pp pretty-printer to Publicsuffix.t.
