Project Shadow Myth Sidecar v0.3.5 — Public Release · Optional Companion
Post-publication effectiveness update — 2026-08-18. CAPA
PS-R1-PRIVATE-MYTH-PUBLIC-BOUNDARY-001isCLOSED_EFFECTIVEfor the separate R1 packaging-boundary correction only. The finding did not apply to Full-Canon Myth v0.3.5. Exact GitHub and Hugging Face redownloads matched the authorized R1.0.1 and Generic Myth v0.2.0 identities, their bounded verifiers passed, and corrected-boundary checks passed across all six GPT Sites. No production or operational deployment is authorized, and no efficacy, safety, certification, legal-compliance, comprehensive-security, or independent-validation claim is made. The release text below retains the publication-time state.

What changed
v0.3.5 is the current public-release successor to v0.3.4. It corrects the package's status vocabulary so public-release status is no longer conflated with R1 admission. Unqualified Myth-package UNADMITTED and OPTIONAL_EXTERNAL_RESEARCH status labels are replaced by explicit public-release, optional-companion, and not-R1-admitted language. The exact v0.3.4 asset remains preserved and unchanged.
No canon mapping, R1 byte, Primitive Commons byte, evidence rule, gate, operational authority, or default-off control was changed. CHANGE_RECEIPT.json identifies the exact predecessor and the bounded successor changes.
Public and optional by design
This exact v0.3.5 archive is authorized for public release as a separate optional companion. It is not part of or required by canonical R1, is not embedded in R1, and remains off unless explicitly enabled. Project Shadow R1 remains fully inspectable, verifiable, evaluable, and usable within its stated PRELIVE scope without it.
AUTHORIZED PUBLIC RELEASE concerns distribution. NONAUTHORIZING concerns evidence, decisions, and action. The sidecar cannot supply evidence, authority, a gate result, a score, routing input, a tool argument, approval, or action, and it does not change R1 verification or human accountability.
CAPA boundary
Open CAPA PS-R1-PRIVATE-MYTH-PUBLIC-BOUNDARY-001 applies only to the older generic Myth v0.1.1 member nested inside the preserved R1 archive. It does not apply to this v0.3.5 sidecar. v0.3.5 does not close that CAPA, reclassify or republish v0.1.1, or alter canonical R1.
Rights boundary
This archive is source-available and mixed-rights; it has no single whole-package open-source license. The complete v0.3.5 package may be copied and redistributed unchanged, with every member and control file intact, only to the extent of rights Phillip Linstrum controls. That package-level permission does not authorize a modified or partial package, third-party material, use of third-party marks, or implied endorsement. Separately scoped Apache-2.0 and CC BY 4.0 component permissions remain unchanged.
All third-party rights remain with their respective holders. No affiliation, endorsement, sponsorship, approval, ownership, legal clearance, or official-canon status is claimed. “Full-Canon” means Project Shadow's maintained interpretive canon only.
Verification
The deterministic package build passed 131 isolated tests with zero skips, all five profile replays, five importable-file tamper rejections with zero payload executions, source verification, and cold verification of a fresh extraction. Two independent builds produced byte-identical ZIPs. Additional changed-byte and unlisted-file tamper checks failed closed as intended.
After extraction, run:
python3 -I -S -B tools/verify_package.py . --run-tests --r1-family-zip /path/to/Project_Shadow_R1_BETA2_Runtime_Successor_Candidate_2026-08-10.zipVerify the byte count and SHA-256 before extraction. GitHub is the canonical custody host; any Hugging Face convenience mirror must carry the same exact ZIP bytes. Do not substitute an automatically generated source archive or repackaged copy. A PASS establishes only the implemented integrity, schema, regression, and bounded compatibility checks. It does not establish safety, efficacy, legal clearance, R1 admission, or production readiness.
