This commit implements the Cargo.lock policy for reproducible builds across all workspace members (pdftract-core, pdftract-cli, pdftract-py). Changes: - Add CONTRIBUTING.md with lockfile-update workflow documentation - Add .renovaterc.json for weekly lockfile-only PRs (human-gated) - Add crates/pdftract-core/README.md with rationale for checked-in lockfiles - Add notes/pdftract-49f8.md with verification note The Argo workflow updates (pdftract-ci.yaml) are committed separately in the declarative-config repo. Acceptance criteria: - PASS: Cargo.lock tracked by git, not in .gitignore - PASS: Argo workflow templates document --locked/--frozen requirements - WARN: Enforcement to be completed when placeholder templates are implemented - WARN: Binary reproducibility verification deferred to pdftract-build-binaries implementation Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

//! Fuzz target for the PDF stream decoder.
|
|
//!
|
|
//! This target tests INV-8 (no panic at public boundary) for the stream decoder.
|
|
//! Any panic indicates a stream decoder bug that must be fixed.
|
|
//!
|
|
//! This also tests EC-10 (decompression bomb) - the 2 GB limit must hold
|
|
//! under random predictor inputs.
