+# Replay and determinism
+
+Deterministic replay lets any scan be reproduced byte for byte. The replay
+system captures every input, environment detail, and output hash.
+
+Core artifacts
+- Replay manifest (canonical JSON)
+- Input bundle (feeds, policies, tools)
+- Output bundle (SBOM, findings, VEX, logs)
+- DSSE envelopes for each artifact
+- Merkle summaries for layers and feed chunks
+
+Replay manifest sections
+- scan: id, time, versions, crypto profile
+- subject: image digest and layer merkle roots
+- inputs: feeds, rules, tool hashes, env normalization
+- policy: lattice and mute hashes
+- outputs: hashes for SBOM, findings, VEX, logs
+- reachability: graph and runtime trace references
+- provenance: signer and optional ledger anchors
+
+Deterministic execution rules
+- Freeze time to scan.time unless explicitly overridden.
+- Use stable ordering for traversal and output serialization.
+- Derive RNG seeds from scan id and layer merkle roots.
+- Canonicalize JSON before hashing or signing.
+
+Verification and CLI
+- stella scan --record produces manifest and bundles.
+- stella verify checks hashes and DSSE signatures.
+- stella replay re-runs with strict or what-if modes.
+- stella diff compares manifests and highlights drift.
+
+Storage
+- replay_runs, bundles, subjects tables in PostgreSQL.
+- CAS locations use content addressed naming.
+
+Offline posture
+- All inputs must be included in the replay bundle.
+- Trust anchors are supplied via RootPack snapshots.

+# Operations runbooks
+
+Runbooks capture operational procedures for incidents, replay verification,
+policy emergencies, and airgap workflows. They are designed to be offline
+and deterministic.
+
+Runbook set (current)
+- docs/runbooks/assistant-ops.md
+- docs/runbooks/incidents.md

+- docs/runbooks/reachability-runtime.md
+- docs/runbooks/replay_ops.md
+- docs/runbooks/vex-ops.md
+- docs/runbooks/vuln-ops.md
+
+Common expectations
+- Hash and store any inbound artifacts with SHA256SUMS.
+- Record UTC timestamps and stable ordering in logs.
+- Avoid external network calls unless explicitly permitted.
+- Keep links to the relevant specs and schemas for verification.
+
+Operational evidence
+- Replay verification logs
+- Policy decision evidence bundles
+- Incident timelines and postmortems
