Julian Noble	01fce6b735	G-126 progress: upstream CLI features landed (extract -d, list -porcelain) ... Upstream punkzip 7f88096 (v2.2.0, suite 128/128) delivers both upstream-side prerequisites from the goal's Approach: the extract-to-directory argument and the machine-readable listing mode with its format pinned by CLI tests. Progress records the v1 porcelain format contract for the parity-suite work; remaining-for-acceptance list trimmed accordingly. Also noted: user-committed reference/ hwzip 2.4 C source upstream (cb2a731). Assisted-by: harness=claude; primary-model=claude-fable-5; api-location=anthropic.com	3 days ago
Julian Noble	eaf5be991c	G-126 progress: upstream zig 0.16.0 port complete + base_offset tests ... Upstream punkzip commits 3b87087 (0.16.0 port, floor moved, Init/Io threading, build-graph install-order fix, msys overlapped-stdout fix, v2.1.3, verified 841-member CRC extraction from the file-relative piperepl kit) and 2e49c75 (three prefixed-zip container tests pinning base_offset for both offset conventions; suite 125/125). Notes gain the overlapped-stdout trap record (applies to the G-128 tool as well); Progress section added with the remaining-for-acceptance list.

Julian Noble	0ad8544ee0	G-126 activated (user-directed): punkzip accelerator work begins ... Status proposed -> active in the index with the detail-file mirror updated. Pre-activation baseline is recorded in the detail file Notes; first work item is the zig 0.16 port of the upstream checkout.

Julian Noble	f153a48d7e	G-126 pre-activation baseline recorded: upstream punkzip 0.15.2 green checkpoint ... Upstream c:/repo/jn/zig/punkzip commits e9b5b553 (0.15.2 migration completed, zig build test 122/122 green - bitstream wiring fixed, CLI suite compiling and pinning current output) and 78453fc0 (localtime banner restored dependency-free on stderr; zeit stays out per user decision). Context refreshed; Notes record the decisions, the stdout/stderr contract, and the known upstream gaps (base_offset untested zig-side, build subcommand scaffolding, 0.16 argsAlloc). Non-contract detail-file updates only; status stays proposed - activation flip awaits user confirmation. goals_lint clean.

Julian Noble	78d9bf238a	G-124 achieved: dependency-free zip reading in punk::zip (punkshell 0.26.0) ... punk::zip could write a zip and split an executable-prefixed one, but nothing in the tree could READ a zip without zipfs, vfs::zip or tcllib's zipfile::decode - a system package punkshell does not vendor, with exactly one consumer: make.tcl's zipfs-less kit extraction. Measured at drafting: msys2's /usr/bin/tclsh8.6 has no tcllib, so a bake driven from that host could not lift the runtime's own zip (its tcl_library) into the kit and the artifact did not boot. punk::zip 0.1.1 -> 0.2.0 adds three commands, stock Tcl only. archive_info reports where the archive begins inside its host file and which offset convention it uses; members walks the central directory and returns one dict per entry without decompressing anything; unzip extracts all or part of it with every member's crc32 verified, directories materialized, and the writer's 2MB whole-member-vs-streaming threshold mirrored. All three accept a plain .zip or a zip attached to an executable or script prefix, so "what is inside this kit / runtime / modpod" is now answerable on a runtime without zipfs. The offset derivation is stated once and shared: offsetbase = cdiroffset - diroffset. Positive means an external preamble with archive-relative offsets, zero means the offsets are file-relative (or there is no preamble); dataoffset is the split point either way. Because every surface reads the ORIGINAL file at that base, the file-relative shape stops being a special case - the broken split-off intermediate is never produced. tclsh90b4_piperepl.exe is the store's one file-relative artifact: the old split-then-tcllib path still fails on it with exactly "Bad zip file. Bad closure.", and it now extracts all 841 members crc-verified in 735ms. extract_preamble consumes that machinery instead of carrying its own scan, and two defects went with the refactor: it read 28 bytes of a 30-byte local file header, and it derived the file-relative base from the FIRST central directory record only (its own '#todo! loop through all cdr file headers'). The shared walk takes the minimum over ALL records and then validates that a PK\3\4 really sits there. Its five puts stdout debug lines are gone. Refusals are decided for every selected member before any file is opened, so an unsupported archive cannot leave a half-populated directory: encrypted entries, zip64 size/offset fields, unknown compression methods, crc mismatch (partial file removed) and member paths that would escape the target are each named. Store and deflate only, mirroring the writer's own primitives. make.tcl's zipfs-less extraction now calls punk::zip::unzip on the original runtime and no longer creates the extracted_<runtime>.zip intermediate. No punkshell code requires zipfile::decode any more. Two categories of hit remain and are deliberate: tcllib's own zip/decode.tcl shipped as a LIBRARY inside some .vfs payloads, and one guarded optional probe inside the vendored third-party ooxml1.10/ooxml.tcl. First tests punk::zip has ever had (src/tests/modules/punk/zip/), covering the three archive shapes from one source tree, the introspection output, the named refusals, and the mkzip -> read round trip - the first coverage that what punkshell WRITES is readable. Verification, all 2026-07-26. Reference host for the dependency-free claim: msys2 tclsh8.6 8.6.12, probed as zipfs / vfs::zip / zipfile::decode all ABSENT - suite driven there harness-free, 28 passed, 2 skipped (the zipfs-gated cross-checks only), 0 failed. 30/30 under Tcl 9.0.3, 28 + 2 skipped under native 8.6. Full source-tree suite after the change: 1142 tests, 1 failure - core/tcl exec-14.3, the documented baseline. Independent cross-check: 868 members of tclsh905.exe extracted byte-identical against the same archive mounted with tcl zipfs. Bake demonstration: 'bake -confirm 0 punk905' driven by the msys2 tclsh8.6 (host=msys-x86_64, target=win32-x86_64) produced extracted_tclsh905.exe/{tcl_library,lib} with no intermediate .zip, and the deployed kit boots with tcl_library at //zipfs:/app/tcl_library, 95 encodings, msgcat 1.7.1, http 2.10.2 - and reads itself with the new reader. Trap worth keeping: zlib stream inflate's 'get' returns only what the stream has already produced, so one get per put silently truncates a large member to the first few chunks (measured 327680 of 5048890 bytes on both 8.6.12 and 9.0.3). The inner drain loop is load-bearing, and the >2MB streaming test exists to catch its removal. Standing question answered and pinned: zipfs does NOT misidentify punk::zip::mkzip directories. It keys on the trailing slash (which punk::zip::walk always emits), not the stored permission bits, exactly as the current cli-999999.0a1.0.tm wording says - the older, less precise wording survives only in frozen module snapshots under src/vfs/mkzipfix.vfs and src/vfs/project.vfs. The real difference from zipfs mkzip is that zipfs writes no directory entries at all. The achieved flip archives the entry and the detail file, and sweeps the live tier: G-034 (the reader is its extract-rather-than-mount alternative, plus the measured finding that make.tcl on 8.6 cannot mount its own templates modpod), G-101 (the read half of a zipfs-less 8.6 container is solved), G-125 (the gate now has a named failure reason to report), G-126 (the member-dict keys and fixture set its parity suite must reproduce, and a back-pointer to G-128 whose only recorded bridge was this goal), G-128 (archive_info answers "is this artifact safe to move the overlay of?" in one call). One acceptance clause is reported for review rather than claimed silently: "NO zipfile::decode requirement remains anywhere in the shipped tree" is satisfied for punkshell's own code, with the vendored-third-party residue named above. The archived detail file's diff is a rename plus the flip's evidence write-up. Assisted-by: harness=claude; primary-model=claude-opus-5[1m]; api-location=anthropic.com	4 days ago
Julian Noble	e1711a7b2a	G-124/G-125/G-126 drafted (user-approved): punk::zip reader, unbootable-kit deploy gate, vendored punkzip accelerator ... Three goals arising from the G-122 work, each drafted with its overlap survey and approved before writing. G-124 - dependency-free zip reading in punk::zip. Nothing in the tree can READ a zip without zipfs, vfs::zip or tcllib's zipfile::decode, which is a system package punkshell does not vendor and which has exactly one consumer: make.tcl's zipfs-less kit extraction. The goal removes that requirement outright (not as an optional fallback), adds an introspection surface so punk::zip is useful to script programmers, and gives the writer its first round-trip coverage. Measured motivation recorded in the detail file: msys2's tclsh8.6 has no tcllib and so bakes an unbootable kit, and extract_preamble's live '#todo - need to adjust offsets' means a FILE-relative prefixed executable (tclsh90b4_piperepl.exe) splits into a .zip tcllib rejects with "Bad closure" - reading the original file at its derived base offset removes that failure mode by construction. G-125 - a kit that cannot boot is not deployed. Today a failed extraction emits a recapped BUILD-WARNING and then deletes and replaces the deployed kit anyway; field- observed 2026-07-26 replacing a working punk91.exe with one that dies on init.tcl. The gate tests the boot precondition on the assembled vfs, so a kit whose payload legitimately supplies its own tcl library still builds. G-126 - punkzip as a VENDORED zip accelerator behind G-124's pure-Tcl floor, with zig kept optional (a tclsh-only clean checkout must still build and bake). Feasibility measured and recorded: the source builds clean under its declared zig 0.15.2, and under 0.16 fails on one surfaced error (std.process.argsAlloc), with the OS-facing surface confined to 3 of ~20 files while the ~10k-line compression core is untouched; zig 0.16.0 is already unpacked in bin/tools. Benchmarks captured for the speedup claim. Non-contract Notes back-pointers added to G-034 (the reader is a candidate for its own Acceptance's "alternative modpod mount path" branch) and G-101 (an 8.6 container has no zipfs, so it needs a reader that works without one).
