• 🔴 [requested-security-review] (08:33) User requested a strict READ-ONLY security/pentest review of frozen v20 in /tmp/opencode/session-recovery-v20-review, covering all 34 changed paths plus necessary context.
• 🔴 [enforced-workflow] (08:33) User prohibited editing, running tests/builds/services, mutating VCS/index/refs, and using recall; required reading applicable guidance and verifying provenance, hashes, and patch applicability before inspection.
• 🔴 (08:33) User specified immutable review inputs: base ab9408c81cc9916177641ae8e9f08624fc27b5b9; patch /tmp/opencode/session-recovery-final-v20.patch with SHA-256 24352107c74d8245fcba7f8571ba0be4b7fc514e6c73cfbf0498f0c25f29f9ba; SEA /home/byk/Code/opencode/packages/opencode/dist/server/opencode-server with SHA-256 d0c78e881892d4f894fab7f6be00643c133ca21f9d2c88ae0d5ff31215393021; 34 changed paths.
• 🟡 (08:33) User asked for adversarial inspection of stale-owner takeover, cancellation/finalizer order, corrupt rows, cross-Session identity, replay, duplicate wake, starvation/DoS, provider/tool/snapshot side effects, transactions, authorization, schema, and generated contracts.
• 🟡 (08:33) User requested specific verification of prior v19 blockers: cancellation remains in phase cancelling and publishes no Step.Interrupted until owner and outer finalizers join; cleanup owns the live exact claim, reconciles unresolved tools/Step, atomically sets cancelled, then clears before successor; publication failure retains cancelling; expired cancelled is safely cleared and cannot wedge; expired cancelling quarantines; snapshot writes have immediate claim checks.
• 🟡 (08:33) User also requested verification that explicit resume of resume:false arms exact ordinary input before acquisition without arming conflicts or recovery continuations.
• 🔴 (08:33) User identified final synchronous check-to-external-call, process-local interruption, and bounded clock skew as disclosed residuals.
• 🔴 (08:33) User required findings first, classified as MUST-FIX or CONCERN, with exact file:line evidence; if there are no findings, the response must explicitly say so; final output must end exactly MERGE or DO-NOT-MERGE.
• 🟡 (08:33) Assistant stated it would first verify frozen inputs and repository state, then inspect all 34 changed paths and relevant call chains without running or modifying anything.
• 🟡 (08:33) Assistant stated the required repo-setup skill was unavailable in the session and that it would follow checked-in guidance directly.
