* feat(artifacts): read Godot PCK packs Add a Godot Engine PCK artifact reader for standalone packs and packs embedded behind an executable trailer (formats 2 and 3). Members are uncompressed byte ranges verified against their declared MD5 on read. Encrypted directories, sparse bundles, patch removal entries, unknown flags and format 1 fail closed as unavailable; encrypted members are reported without being read. inspect-artifact and extract-artifact recognize standalone packs by their GDPC magic. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(artifacts): bound Godot PCK metadata and own member streams Cap member paths at 4096 bytes and the retained directory at 64 MiB before allocation. Read members with positional chunk reads through pipeline so cancellation is typed, abandoned consumers release their source, and the shared descriptor stays reader-owned. Retain the root descriptor for godot-pck inventory, as for ZIP and universal Mach-O. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(artifacts): complete Godot PCK facts, integrity and selected views * fix(artifacts): preserve atomic-root inventory Evidence * fix(artifacts): bound aggregate PCK member expansion --------- Co-authored-by: Samucahub <151155051+Samucahub@users.noreply.github.com> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: gensokyo-dev <342580529+gensokyo-dev@users.noreply.github.com>

* Shared aggregate plaintext-work ceiling for archive-backed operations.
|
|
* ZIP compression and PCK aliases can both multiply hashing and output bytes.
|
|
* Charge every readable logical occurrence, including repeated physical ranges.
|
|
*
|
|
* Keep the existing ZIP policy: a 256 MiB floor and 500 times the encoded archive
|
|
* size. Large real packages retain proportionally large budgets without granting
|
|
* a fixed per-member allowance. PCK callers use the actual pack span, excluding
|
|
* an embedded executable carrier. The safe-integer ceiling preserves exact byte
|
|
* accounting at the JSON/number boundary.
