+# QCrows All the Way Down: One VM-Image Format, Three Projects, Zero Trust Between Them
+
+*How SysDeck 0.4.6 became a first-class consumer of the in-house QCrows VM container image format — parsing image manifests straight out of tar.gz in memory, re-implementing the master toolchain's verification checks without extracting a single byte to disk, and rendering real image metadata in the Kata panel. The same format is produced by cockpit-kata's qcrows-pack and by AI-LSC's stack exporter; SysDeck verifies both with the same code path.*
+
+A QCrows image (`.qcrows`, spec v0.2.0) is a self-describing bundle for VM-based container runtimes: one tarball carrying a `metadata.toml` manifest, a Cockpit `menu.toml` entry, a `hashes.sha256` integrity list, the guest `rootfs.tar.gz`, and — mandatory since v0.2 — the guest kernel and its `.config`. The format's master implementation lives in the cockpit-kata project (`qcrows-pack`, `qcrows-verify`, `qcrows-inspect`, `qcrows-export`), and a second producer now exists: AI-LSC, the local AI stack manager, exports its active tool stack directly as `.qcrows` archives. SysDeck's Kata panel has listed whatever sat in `/usr/share/sysdeck/kata/qcrows/` since the v0.0.43 production rewrite — but until now it only ever looked at filenames. A bundle could be a Kata-tuned Alpine image or someone's holiday photo archive; the panel treated both as "a file with a size."
+
+v0.4.6 closes that gap by making the bridge a real format consumer. `qcrows-list` opens every archive in the directory with Python's `tarfile` in `r:*` mode and reads `metadata.toml` and `menu.toml` into memory — no extraction, no temp directories, nothing executable ever materialized from an image the operator hasn't chosen to trust. The TOML parser is deliberately small: QCrows metadata is a flat shape of `[ section ]` headers and scalar/array values, so ~40 lines of section-aware parsing cover it — and being section-aware is not cosmetic. The master `qcrows-inspect` greps first-matching keys, which reports the kernel's `size_mb` on the rootfs row of its own output; SysDeck's parser tracks the current section and gets `kernel.size_mb` and `rootfs.size_mb` right on the same files the master tool mislabels.
+
+The new `qcrows-verify` subcommand mirrors the master verifier check-for-check — required files, rootfs presence, kernel binary with a real magic test (bzImage's `HdrS` at offset 0x202, or ELF), the kernel `.config` with the five Kata-required options, and a full `sha256sum -c`-style walk of every entry in `hashes.sha256` — with two deliberate divergences in *how*, not *what*. First, the kernel check classifies bytes directly instead of shelling out to `file`: same verdicts, no subprocess. Second, the semantics are calibrated to the master's own exit codes: a missing kernel is a hard failure, but a shortfall of `CONFIG_VSOCKETS=y`-style options is a *warning*, exactly as in qcrows-verify, so a host-kernel-built bundle reports ok with advisories rather than failing a check the master would pass. The hash walk streams members in 1 MiB chunks and caps parsed text members at 1 MiB, header counts at ten thousand — tar-bomb posture inherited from the bridge's CVE-lesson hardening style.
+
+Everything runs through the same security gate the rest of the Kata bridge uses: filenames validated against the strict allowlist regex, paths resolved with `realpath` containment under the bundle directory, output sanitized before it reaches JSON. The panel card grew accordingly — image name and version, kernel version and format, architecture, hypervisor compatibility list, per-row Verify and Inspect actions whose output lands in the existing operation-output card, all rendered through `textContent`/`escapeHtml` per the panel's no-innerHTML rule. Legacy non-QCrows tarballs that happen to sit in the directory degrade to a stat-only row with an honest "(not a QCrows archive)" label instead of being silently miscounted.
+
+The test discipline is where the three-project story pays off. The new suite builds synthetic spec-conformant archives in a temp directory — including one whose `rootfs.tar.gz` is byte-flipped *after* its hashes are computed, which is what an integrity violation actually is — and additionally exercises the bridge against real images from both external producers: an AI-LSC stack export and a bundle from cockpit-kata's own `qcrows-pack`. Both parse, both verify clean, the tampered one fails on exactly the checksum check. One image format, two independent producers, one consumer that trusts none of them until the hashes say otherwise — which is the whole point of a self-describing format.

 # SysDeck and the Cockpit Inheritance: One Module Catalog, Two Frontends, and the Case for Real Host State
 
 *A technical walkthrough of how SysDeck 0.4.4 — a standalone Linux operations console (thirty-one panels, one Bun process, no Cockpit required) that also ships as a drop-in Cockpit plugin suite — authenticates against the host's own Unix accounts through PAM exactly the way Cockpit does, keeps every module working in both frontends, holds itself to a compiler-enforced no-demo contract where every panel reads real host state or fails honestly, and resolves every fork in the road with a step-down through the system's real tools: ten package managers from pacman to sorcery, nftables before iptables, lm-sensors before raw sysfs. Grounded in the source code, not in marketing claims.*

 # SysDeck - Work Log
 
+---
+Task ID: 48
+Agent: Main Orchestrator (v0.4.6 QCrows format-aware Kata bridge)
+Task: Per user directive: "lets now update SysDeck to be sure it also uses qcrows the same way" — align SysDeck with the real QCrows VM container image format (cockpit-kata master implementation, qcrows-spec.md v0.2.0), the same format AI-LSC now exports. The bridge must be a real format consumer, not a filename lister.
+
+Work Log:
+- FORMAT-AWARE qcrows-list (bridge/kata.py): every .qcrows / .qcrows.gz / .tar.gz / .tgz in /usr/share/sysdeck/kata/qcrows/ is opened in memory (tarfile r:* — nothing extracted to disk, nothing executable materialized) and its metadata.toml + menu.toml parsed by a new section-aware mini-TOML parser (_qcrows_parse_toml — [ section ] headers, dotted sections, strings/bools/ints/arrays; being section-aware deliberately fixes the first-match grepping quirk in cockpit-kata's own qcrows-inspect, which reports kernel size_mb on the rootfs row). Each list entry now carries qcrows, format_version, image{name,version,description,arch,created_at}, kernel{version,format,path,...}, rootfs, initrd, hypervisors, menu{label,category}, kernel_binary_present, has_kernel_config, has_boot_params, members. Legacy non-QCrows tarballs degrade gracefully to stat-only entries (qcrows:false + error note). Added .qcrows.gz to the extension filter.
+- NEW SUBCOMMAND qcrows-inspect <filename>: single-image detail — full metadata record plus the sorted member listing (name/size/mode) and build.toml provenance.
+- NEW SUBCOMMAND qcrows-verify <filename>: in-memory verification mirroring cockpit-kata's master qcrows-verify checks: (1) required files metadata.toml/menu.toml/hashes.sha256, (2) rootfs.tar.* present, (3) kernel binary present + magic classification (bzImage "HdrS" @0x202 / ELF \x7fELF — the no-subprocess equivalent of the master's `file | grep (ELF|Linux.*boot)`), (4) kernel/config present (hard check) + the five required Kata options CONFIG_VSOCKETS/VIRTIO/VIRTIO_PCI/DEVTMPFS/DEVTMPFS_MOUNT (WARNINGS only — matches master exit-code semantics where option shortfalls never fail), (5) initrd presence (warn), (6) metadata format_version + hypervisors declared, (7) full sha256sum -c style hash walk streaming members in 1 MiB chunks. Returns {ok, passed, failed, warnings, checks[]}.
+- SECURITY POSTURE (unchanged gates, new surface): filenames validated with _validate_filename; paths resolved with _resolve_path_under_base realpath containment under QCROWS_DIR; tar-bomb guards (10,000 member cap, 1 MiB cap on parsed text members); output sanitized via _sanitize_output; traversal/oversize/garbage names rejected with {error: ...} (tested).
+- BRIDGE CLIENT (shared/bridge.js): kata surface gains qcrowsInspect(filename) + qcrowsVerify(filename) proxying to the new subcommands; header comment updated to document format-aware listing.
+- KATA PANEL (plugins/sysdeck-kata/kata.js): QCrows card renamed to "QCrows VM Container Images" with enriched rows — image name+version (filename as secondary line), kernel version · format (+ missing-binary marker), arch, hypervisors, size, modified — plus per-row Verify and Inspect buttons. Verify renders a PASS/FAIL/WARN check list (green/red via the existing output card, textContent only — no innerHTML on bridge data); Inspect dumps the full JSON detail. Empty-state text updated to the qcrows-pack invocation and notes AI-LSC can export the stack directly as .qcrows. Legacy rows show "(not a QCrows archive)" and disable Verify.
+- VERSION-SYNC TEST HARDENING: test_version_sync_all_surfaces_report_020 hardcoded the 0.4.5 literal and failed on every bump; it now derives the expected version from the Makefile's own VERSION line (single source of truth), so it stays green whenever the surfaces move together and red when they drift.
+- TESTS (tests/test_bridge_parsers.py): dispatch-set assertion updated for the two new subcommands; new TestQcrowsFormatBridge class (11 tests) with a _build_qcrows() synthetic archive builder that mirrors qcrows-pack's layout (./-prefixed members, sha256sum-format hashes, real bzImage magic): list parses metadata/menu; legacy tarball degrades; verify passes on valid image; detects tampered payload (hashes computed BEFORE the byte-flip — that is what an integrity violation means); fails when kernel missing; warns-but-passes on missing Kata options; inspect returns member listing; traversal/bad-name/missing-file rejection; TOML parser section-awareness; kernel magic classification (bzimage/elf/unknown — boundary fixed to len>=0x206).
+- BUG FIX (adjacent, found by the suite in this environment): bridge/integrity.py score() caught only FileNotFoundError; on hosts where lynis ran as root, /var/log/lynis.log is root-only (-rw-r-----) and unprivileged sessions crashed with PermissionError. Now catches OSError and degrades to None (the honest "no score for us" state).
+- CROSS-PRODUCER VALIDATION: bridge exercised against real images from BOTH producers — an AI-LSC stack export (.qcrows) and a bundle from cockpit-kata's own qcrows-pack (.qcrows.gz). Both parse (image name/kernel/hypervisors/menu correct) and both verify ok with identical warning sets; a tampered copy fails exactly the SHA-256 check.
+- VERSION SYNC: bumped 0.4.5 → 0.4.6 across all 9 release surfaces: Makefile VERSION, bridge/__init__.py __version__, packaging/setup.py VERSION, packaging/PKGBUILD pkgver, packaging/sysdeck.spec Version + prepended %changelog entry, packaging/debian/changelog prepended entry, compat/compat-manifest.json version, README.md badge + Version line, BLOG.md prepended v0.4.6 section.
+
+GUARDS:
+- make check: all build-time guards pass — manifest consistency, metainfo consistency, Makefile tab indentation, cockpit import patterns, bridge invocation patterns, bridge.js↔Python subcommand cross-check (the two new qcrows calls verified against kata.py COMMANDS), version sync (all surfaces 0.4.6).
+- All 277 unit tests pass (266 prior + 11 new QCrows tests).
+- bridge/kata.py + bridge/integrity.py pass py_compile; kata.js + bridge.js pass node --check (ESM).
+- CLI smoke: `python3 bridge/kata.py qcrows-list` returns [] on hosts without /usr/share/sysdeck/kata/qcrows (real empty state, exit 0).
+
+Stage Summary:
+- v0.4.6 makes SysDeck a first-class QCrows consumer with the same format understanding as the producer side: format-aware listing (metadata.toml + menu.toml parsed in memory), single-image inspection, and master-mirroring verification (kernel magic, config, full hash walk) — all under the bridge's existing security gates, nothing extracted to disk. The Kata panel surfaces the metadata with Verify/Inspect actions. Verified against real images from both producers (ai-lsc exporter + cockpit-kata qcrows-pack) plus synthetic tamper/kernel-missing/security cases in the suite. Adjacent robustness fix: integrity.score() degrades to None on PermissionError. All 9 release surfaces report 0.4.6; all make-check guards pass; 277/277 tests pass.
