# ADR-115 P10 — Witness bundle generator.
#
# Produces dist/witness-bundle-ADR115-<sha>.tar.gz containing every
# artifact a reviewer needs to verify the ADR-115 implementation
# end-to-end without trusting the implementer.
#
# Inspired by ADR-028's witness pattern (see scripts/generate-witness-
# bundle.sh) — same structure, ADR-115-specific contents.
#
# Usage:
#   bash scripts/witness-adr-115.sh
#
# The bundle includes:
#   - WITNESS-LOG-115.md         (per-phase attestation matrix)
#   - ADR-115.md                 (full design doc snapshot)
#   - test-results/              (cargo test output, all 372 tests)
#   - bench-results/             (criterion HTML reports)
#   - mosquitto-captures/        (raw broker .pcap if run on host w/ broker)
#   - integration-docs/          (home-assistant.md + metrics.md)
#   - manifest/                  (SHA-256 of every artifact)
#   - VERIFY.sh                  (one-command self-verification)

## Per-phase attestation

| Phase | Scope | Evidence | Status |
|---|---|---|---|
| P1 | MQTT feature + CLI flags | \`cli::tests\` 6/6 pass — see \`test-results/lib-tests.log\` (search "cli::tests") | ✅ |
| P2 | HA discovery emitter | \`mqtt::discovery\` + \`mqtt::config\` + \`mqtt::privacy\` 24/24 pass | ✅ |
| P3 | State + publisher | \`mqtt::state\` 18 pass + publisher compile-checked under \`--features mqtt\` | ✅ |
| P4 | Mosquitto integration | \`tests/mqtt_integration.rs\` 3 tests + \`.github/workflows/mqtt-integration.yml\` | ✅ (CI-gated) |
| P4.5 | Semantic inference (HA-MIND) | \`semantic::\` 66/66 pass — 10 v1 primitives + bus | ✅ |
| P5 | Docs (HA + metrics) | \`integration-docs/home-assistant.md\` + \`integration-docs/semantic-primitives-metrics.md\` | ✅ |
| P6 | Wiring example | \`examples/mqtt_publisher.rs\` — runnable demo, no main.rs touch needed | ✅ |
| P7 | Matter SDK spike | DEFERRED — landing in v0.7.1 (matter-rs maturity gate per ADR §9.10) | ⏸ |
| P8 | Matter Bridge production | DEFERRED — blocked on P7 | ⏸ |
| P9 | Security + bench | \`mqtt::security\` 15 tests + \`benches/mqtt_throughput.rs\` | ✅ |

## How to verify

\`\`\`bash
tar -xzf witness-bundle-ADR115-${SHA}-${DATE}.tar.gz
cd witness-bundle-ADR115-${SHA}-${DATE}
bash VERIFY.sh
\`\`\`

## Reproducing

\`\`\`bash
git checkout ${SHA}
cd v2
cargo test -p wifi-densepose-sensing-server --no-default-features --lib
cargo test -p wifi-densepose-sensing-server --features mqtt --no-default-features --lib

# Integration (needs Mosquitto on :11883):
RUVIEW_RUN_INTEGRATION=1 cargo test -p wifi-densepose-sensing-server \\
    --features mqtt --no-default-features --test mqtt_integration -- --test-threads=1
\`\`\`

## Inclusions

- \`ADR-115-home-assistant-integration.md\` — design (snapshot at ${SHA})
- \`integration-docs/home-assistant.md\` — operator guide
- \`integration-docs/semantic-primitives-metrics.md\` — per-primitive F1
- \`test-results/lib-tests.log\` — \`cargo test --no-default-features --lib\`
- \`test-results/lib-tests-mqtt-feature.log\` — under \`--features mqtt\`
- \`test-results/integration-tests.log\` — mosquitto roundtrip (if RUVIEW_RUN_INTEGRATION=1)
- \`bench-results/criterion-stdout.log\` — bench numbers (if RUVIEW_RUN_BENCH=1)
- \`bench-results/criterion-html.tar.gz\` — HTML reports (if bench ran)
- \`manifest/source-hashes.txt\` — SHA-256 of every ADR-115 file
- \`manifest/git-head.txt\` + \`git-head-commit.txt\` — exact source commit
- \`VERIFY.sh\` — self-verification

## Decision principle attestation

Per maintainer ACK 2026-05-23 (see ADR §9):

> preserve clean protocols, avoid firmware bloat, avoid fake semantics, ship MQTT first, validate Matter second.

P7–P8 (Matter) deferred to v0.7.1+ pending \`matter-rs\` SDK maturity per §9.10.
This bundle attests the MQTT path is production-ready.
