+## Advisory Feed Packaging (DEVOPS-AIAI-31-002)
+
+Package advisory feeds (SBOM pointers + provenance) for release/offline kit:
+
+```bash
+# Production (CI with COSIGN_PRIVATE_KEY_B64 secret)
+./ops/deployment/advisory-ai/package-advisory-feeds.sh
+
+# Development (uses tools/cosign/cosign.dev.key)
+COSIGN_ALLOW_DEV_KEY=1 COSIGN_PASSWORD=stellaops-dev \
+  ./ops/deployment/advisory-ai/package-advisory-feeds.sh
+```
+
+Outputs:
+- `out/advisory-ai/feeds/advisory-feeds.tar.gz` - Feed bundle
+- `out/advisory-ai/feeds/advisory-feeds.manifest.json` - Manifest with SBOM pointers
+- `out/advisory-ai/feeds/advisory-feeds.manifest.dsse.json` - DSSE signed manifest
+- `out/advisory-ai/feeds/provenance.json` - Build provenance
+
+CI workflow: `.gitea/workflows/advisory-ai-release.yml`
+
 ## Evidence to attach (sprint)
 - Helm release output (rendered templates for advisory AI)
 - `docker-compose config` with/without GPU overlay
 - Offline kit metadata listing advisory AI images + SBOMs
+- Advisory feed package manifest with SBOM pointers

+# AOC Backfill Release Plan (DEVOPS-STORE-AOC-19-005-REL)
+
+Scope: Release/offline-kit packaging for Concelier AOC backfill operations.
+
+## Prerequisites
+- Dataset hash from dev rehearsal (AOC-19-005 dev outputs)
+- AOC guard tests passing (DEVOPS-AOC-19-001/002/003 - DONE)
+- Supersedes rollout plan reviewed (ops/devops/aoc/supersedes-rollout.md)
+
+## Artefacts
+- Backfill runner bundle:
+  - `aoc-backfill-runner.tar.gz` - CLI tool + scripts
+  - `aoc-backfill-runner.sbom.json` - SPDX SBOM
+  - `aoc-backfill-runner.dsse.json` - Cosign attestation
+- Dataset bundle:
+  - `aoc-dataset-{hash}.tar.gz` - Seeded dataset
+  - `aoc-dataset-{hash}.manifest.json` - Manifest with checksums
+  - `aoc-dataset-{hash}.provenance.json` - SLSA provenance
+- Offline kit slice:
+  - All above + SHA256SUMS + verification scripts
+
+## Packaging Script
+
+```bash
+# Production (CI with secrets)
+./ops/devops/aoc/package-backfill-release.sh
+
+# Development (dev key)
+COSIGN_ALLOW_DEV_KEY=1 COSIGN_PASSWORD=stellaops-dev \
+  DATASET_HASH=dev-rehearsal-placeholder \
+  ./ops/devops/aoc/package-backfill-release.sh
+```
+
+## Pipeline Outline
+1) Build backfill runner from `src/Aoc/StellaOps.Aoc.Cli/`
+2) Generate SBOM with syft
+3) Sign with cosign (dev key fallback)
+4) Package dataset (when hash available)
+5) Create offline bundle with checksums
+6) Verification:
+   - `stella aoc verify --dry-run`
+   - `cosign verify-blob` for all bundles
+   - `sha256sum --check`
+7) Publish to release bucket + offline kit
+
+## Runbook
+1) Validate AOC guard tests pass in CI
+2) Run dev rehearsal with test dataset
+3) Capture dataset hash from rehearsal
+4) Execute packaging script with production key
+5) Verify all signatures and checksums
+6) Upload to release bucket
+7) Include in offline kit manifest
+
+## CI Workflow
+`.gitea/workflows/aoc-backfill-release.yml`
+
+## Verification
+```bash
+# Verify bundle signatures
+cosign verify-blob \
+  --key tools/cosign/cosign.dev.pub \
+  --bundle out/aoc/aoc-backfill-runner.dsse.json \
+  out/aoc/aoc-backfill-runner.tar.gz
+
+# Verify checksums
+cd out/aoc && sha256sum -c SHA256SUMS
+```
+
+## Owners
+- DevOps Guild (pipeline + packaging)
+- Concelier Storage Guild (dataset + backfill logic)
+- Platform Security (signing policy)

+# Findings Ledger Packs Infrastructure
+
+## Scope
+Infrastructure for snapshot/time-travel export packaging and signing.
+
+## Tasks Covered
+- DEVOPS-LEDGER-PACKS-42-001-REL: Snapshot/time-travel export packaging
+- DEVOPS-LEDGER-PACKS-42-002-REL: Pack signing + integrity verification
+
+## Components
+
+### 1. Pack Builder
+Creates deterministic export packs from Ledger snapshots.
+
+```bash
+# Build pack from snapshot
+./ops/devops/ledger/build-pack.sh --snapshot-id <id> --output out/ledger/packs/
+
+# Dev mode with signing
+COSIGN_ALLOW_DEV_KEY=1 ./ops/devops/ledger/build-pack.sh --sign
+```
+
+### 2. Pack Verifier
+Verifies pack integrity and signatures.
+
+```bash
+# Verify pack
+./ops/devops/ledger/verify-pack.sh out/ledger/packs/snapshot-*.pack.tar.gz
+```
+
+### 3. Time-Travel Export
+Creates point-in-time exports for compliance/audit.
+
+```bash
+# Export at specific timestamp
+./ops/devops/ledger/time-travel-export.sh --timestamp 2025-12-01T00:00:00Z
+```
+
+## Pack Format
+```
+snapshot-<id>.pack.tar.gz
+├── manifest.json          # Pack metadata + checksums
+├── findings/              # Finding records (NDJSON)
+├── metadata/              # Scan metadata
+├── provenance.json        # SLSA provenance
+└── signatures/
+    ├── manifest.dsse.json # DSSE signature
+    └── SHA256SUMS         # Checksums
+```
+
+## CI Workflows
+- `ledger-packs-ci.yml` - Build and verify packs
+- `ledger-packs-release.yml` - Sign and publish packs
+
+## Prerequisites
+- Ledger snapshot schema finalized
+- Storage contract defined
+- Pack format specification
