From 990f5e37117b5761a04a50572fa4aef6838ea546 Mon Sep 17 00:00:00 2001 From: Parfii-bot Date: Thu, 23 Apr 2026 00:49:49 +0800 Subject: [PATCH 1/4] =?UTF-8?q?fix(substrate):=20E1=20=E2=80=94=20kei-atom?= =?UTF-8?q?-discovery=20shared=20crate=20+=204=20critical=20security=20fix?= =?UTF-8?q?es?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extracts authoritative atom discovery + frontmatter parsing into new crate _primitives/_rust/kei-atom-discovery/. kei-sage and kei-runtime now both consume the same implementation, eliminating Frontmatter drift. Resolved findings: - F-3/crit#3: path traversal via md_dir.join() — safe_join helper rejects absolute paths + .. components + post-canonicalise escapes (4 sites) - crit#6/architect P0-a: Frontmatter drift — single AtomMeta struct - SA supply-chain: serde_yaml archived — migrated to serde_yaml_ng 0.10 - crit#2: JSON Schema $ref SSRF — jsonschema 0.17→0.18 with resolve-file feature only, custom LocalFileResolver denies non-file:// schemes - F-4: symlink traversal — walkdir follow_links(false) explicit everywhere - F-5: YAML billion-laughs — 64 KiB pre-parse cap Tests: 9/9 new crate + 23/23 sage + 2/2 runtime + 7/7 kei-task = 41/41 green.

Schema amendment A-1 (architect P0-a, non-breaking clarification): input.schema and output.schema are REQUIRED for all atom kinds. The shared kei-atom-discovery parses them as Option only to allow tolerant skip-on-missing (stderr warn), not to permit absent schemas. Resolves Stream C / Stream D enforcement asymmetry documented in critic finding #6. 2. Cross-stream integration test (architect P0-b): tests/substrate_integration.sh builds release binaries, scaffolds a test atom corpus, runs schema-lint + list-atoms + atoms-discover + invoke; asserts all four streams agree on the same atom corpus and exit codes honour the locked §Runtime contract. Previously missing — only manual smoke checks existed. 3. Fix regression introduced by E1's jsonschema 0.18 upgrade: "relative URL without a base" on compile when schema declared a relative $id like "kei-task/atoms/schemas/create-input.json". validate.rs now synthesises an absolute file:// $id from the canonicalised schema path before compile. Internal $refs still resolve relative to the schema file; LocalFileResolver still confines to the schema's parent dir. Integration test catches this.
