# 001 — Enforce UCXL Address Validation at Boundaries
- Area: `pkg/dht/encrypted_storage.go`, `pkg/ucxi/server.go`, `pkg/ucxl/*`
- Priority: High
## Background
Current DHT storage and UCXI endpoints accept any string as an address. In `encrypted_storage.go` the `ucxl.Parse` validation is commented out, and UCXI relies on downstream behavior. This allows malformed inputs to enter storage and makes discovery/search unreliable.
## Scope / Deliverables
- Enforce strict `ucxl.Parse` validation in:
- `EncryptedDHTStorage.StoreUCXLContent` and `RetrieveUCXLContent`.
- UCXI handlers (`handleGet/Put/Post/Delete/Navigate`).
- Return structured UCXL validation errors (see Issue 004 for payloads).
- Add unit tests for valid/invalid examples, including temporal segments and paths.
- Document accepted grammar in README + link to CHORUS knowledge pack.
## Acceptance Criteria / Tests
- Invalid addresses return UCXL-400-INVALID_ADDRESS with details.field=address.
- Valid addresses round-trip through UCXI and DHT without errors.
- Tests cover: agent:role@project:task, temporal segments, and path edge cases.
## Notes
- Align temporal grammar with Issue 011 decisions.

# 002 — Fix Search Parsing Bug in Encrypted Storage
- Area: `pkg/dht/encrypted_storage.go`
- Priority: High
## Background
`matchesQuery` splits `metadata.Address` by `:` to infer agent/role/project/task. UCXL addresses include scheme, temporal segment, and path, so colon-splitting misparses and yields false matches/negatives.
## Scope / Deliverables
- Replace naive splitting with `ucxl.Parse(address)` and use parsed fields.
- Add defensive checks for temporal and path filters (if later extended).
- Unit tests: positive/negative matches for agent/role/project/task, and content_type/date range.
## Acceptance Criteria / Tests
- Search with agent/role/project/task returns expected results on cached entries.
- No panics on unusual addresses; invalid addresses are ignored or logged.
## Notes
- Coordinate with Issue 001 to ensure all stored addresses are valid UCXL.

# 003 — Wire UCXI P2P Announce and Discover
- Area: `pkg/ucxi/resolver.go`, `pkg/ucxi/server.go`, `pkg/dht/encrypted_storage.go`, `pkg/dht/*`
- Priority: High
## Background
UCXI resolver has hooks for P2P `Announce`/`Discover` but theyre not connected. DHT announcements currently store a single peer and `DiscoverContentPeers` returns at most one peer.
## Scope / Deliverables
- Implement resolver hooks using DHT:
- Announce: write provider records or announcement values for multiple peers.
- Discover: query providers/announcements and return a list of `ResolvedContent` sources.
- Store peer lists, not just a single peer, and deduplicate.
- Cache discovered results with TTL in resolver.
## Acceptance Criteria / Tests
- Announcing content from multiple nodes produces multiple discoverable sources.
- UCXI `/discover` returns >1 result when multiple providers exist.
- Unit/integration tests simulate 23 nodes (can mock DHT interfaces).
## Notes
- Longer-term: switch from GetValue/PutValue to Kademlia provider records for scalability.

# 004 — Standardize UCXI Payloads to UCXL Codes
- Area: `pkg/ucxi/server.go`, shared responders/builders
- Priority: Medium-High
## Background
UCXI responses currently use a custom `Response` shape and plain HTTP status. The repo defines UCXL error/response codes and builders (see Rust `ucxl_codes.rs` analog). Clients need stable shapes and codes.
## Scope / Deliverables
- Introduce UCXL response/error builders in Go with fields:
- Success: `{response: {code, message, data?, details?, request_id, timestamp}}`
- Error: `{error: {code, message, details?, source, path, request_id, timestamp, cause?}}`
- Map common cases: 200/201, 400 INVALID_ADDRESS, 404 NOT_FOUND, 422 UNPROCESSABLE, 500 INTERNAL.
- Update all UCXI handlers to use builders and include `request_id`.
## Acceptance Criteria / Tests
- Unit tests assert exact JSON for success/error cases.
- Manual GET/PUT/DELETE/Navigate show UCXL-20x/40x codes and messages.
## Notes
- Coordinate with Issue 001 so invalid addresses surface UCXL-400-INVALID_ADDRESS with details.field=address.

# 005 — Election Heartbeat on Admin Transition
- Area: `main.go`, `pkg/election/*`
- Priority: Medium
## Background
Heartbeat loop starts only if this node is admin at startup. When admin changes via callback, role config is applied but no new heartbeat loop is launched. Risk: missed heartbeats post-takeover.
## Scope / Deliverables
- Start/stop admin heartbeat within the election callback based on current winner.
- Ensure single heartbeat goroutine per admin node; cleanly stop on demotion/shutdown.
- Log state transitions and errors.
## Acceptance Criteria / Tests
- In tests/sim, when admin role transfers, the new admin begins heartbeating within `HeartbeatTimeout/2`.
- No duplicate heartbeats; demoted node stops sending heartbeats.
## Notes
- Consider encapsulating heartbeat management inside `ElectionManager`.

# 006 — Health Checks: Active Probes for PubSub and DHT
- Area: `main.go`, `pkg/health/*`, `pubsub/*`, `pkg/dht/*`
- Priority: Medium
## Background
Health checks for PubSub and DHT currently return static "healthy" messages. They should perform live probes to detect real outages.
## Scope / Deliverables
- PubSub check: publish a transient message to a loopback test topic and await receipt within timeout.
- DHT check: put/get a small test value under a temporary key; measure latency.
- Include metrics (latency, last success time) in health details.
## Acceptance Criteria / Tests
- When pubsub or DHT is down, health check reports unhealthy with reason.
- When restored, checks turn healthy and update timestamps.
## Notes
- Keep probe frequency/configurable to avoid noise.

# 007 — DHT Replication and Provider Records
- Area: `pkg/dht/*`
- Priority: Medium
## Background
Current DHT layer uses simple PutValue/GetValue and single-peer announcements. For scale and resilience, use provider records and configurable replication.
## Scope / Deliverables
- Add provider record publishing for UCXL content keys; discover providers via Kademlia provider API.
- Implement basic replication policy: target replication factor, periodic reprovide, and cleanup.
- Track providers in metadata (peer IDs) and return multiple sources in `DiscoverContentPeers`.
## Acceptance Criteria / Tests
- Multiple nodes can become providers for the same UCXL key; discovery returns all.
- Reprovide job runs on schedule; metrics expose counts.
## Notes
- Coordinate with Issue 003 so UCXI resolver consumes provider results.

# 008 — Security: Key Rotation and Access Policies
- Area: `pkg/crypto/*`, `pkg/config/config.go`, `pkg/dht/encrypted_storage.go`
- Priority: Medium
## Background
Age/Shamir tests run at startup, but SecurityConfig (key rotation, audit logging) is not enforced. Role-based access beyond encryption is not audited/policy-gated.
## Scope / Deliverables
- Enforce `SecurityConfig`:
- Key rotation interval respected; emit warnings/events when due.
- Audit log writes for Store/Retrieve/Announce with role and node id.
- Role-based access policy hook prior to store/retrieve; deny or log violations.
## Acceptance Criteria / Tests
- Rotations generate audit entries and update keys per policy (mocked acceptable).
- Audit log contains append-only entries for sensitive operations.
## Notes
- Coordinate with SHHH/keys component when available for centralized policy.

# 009 — Integration Tests: UCXI + DHT Encryption + Search
- Area: tests under `pkg/ucxi/`, `pkg/dht/`, e2e harness
- Priority: Medium
## Background
There are good unit tests across modules, but no end-to-end UCXI HTTP tests through encrypted DHT and back, nor tests proving address-based search works with full UCXL strings.
## Scope / Deliverables
- Add UCXI HTTP tests using httptest:
- PUT content at valid UCXL addresses (with temporal), GET back exact bytes.
- DELETE + 404 on subsequent GET.
- Encrypted DHT path tests (mocked DHT ok): assert encrypt/decrypt with role.
- Search tests that insert multiple cached entries and verify agent/role/project/task filters.
## Acceptance Criteria / Tests
- `go test ./...` passes and includes new UCXI/DHT e2e cases.
- Invalid addresses during PUT/GET return UCXL-400 codes (after Issue 004).
## Notes
- Consider a small fake DHT interface to keep tests hermetic.

# 010 — Status Endpoints and Config Surface
- Area: `pkg/ucxi/server.go`, `main.go`, `pkg/dht/encrypted_storage.go`
- Priority: Low-Medium
## Background
Runtime visibility into DHT/UCXI/hybrid status is limited. Operators need quick status: enabled flags, providers, cache sizes, metrics, and current election state.
## Scope / Deliverables
- UCXI `/status` returns: resolver registry stats, storage metrics (cache size, ops), P2P enabled flags.
- Main prints or exposes a simple local HTTP endpoint aggregating election/admin state and peer counts (could reuse existing health HTTP).
- Documentation for operators.
## Acceptance Criteria / Tests
- Hitting `/status` returns JSON with counts and timestamps.
- Health HTTP shows admin node id and connected peers.
## Notes
- Keep payloads small; avoid leaking secrets.

# 011 — Align Temporal Grammar and Documentation
- Area: `pkg/ucxl/address.go`, `pkg/ucxl/temporal.go`, docs
- Priority: Medium
## Background
Temporal grammar in code uses `*^`, `*~`, `*~N`, plus `~~N`/`^^N`. MASTER PLAN describes symbols like `#`, `~~`, `^^`, `~*`, `^*`. The mismatch causes confusion across modules and docs.
## Scope / Deliverables
- Decide on canonical temporal grammar and implement parser support and stringer consistently.
- Provide mapping/back-compat if needed (e.g., accept both but emit canonical form).
- Update UCXL docs in repo (and knowledge pack references) to match.
## Acceptance Criteria / Tests
- Parser accepts canonical forms; unit tests cover all temporal cases.
- String() emits canonical form; round-trip stable.
## Notes
- Coordinate with RUSTLE and Validator modules for cross-language parity.

# 012 — SLURP Idempotency, Backpressure, and DLQ
- Area: `pkg/integration/slurp_client.go`, `pkg/integration/slurp_events.go`, config
- Priority: High
## Background
SLURP event delivery has retries and batching but lacks idempotency keys, circuit-breaking/backpressure, and a dead-letter queue (DLQ). Under failure/load this can produce duplicates or data loss.
## Scope / Deliverables
- Idempotency:
- Generate a stable idempotency key per event (e.g., hash of {discussion_id, event_type, timestamp bucket}).
- Send via header `Idempotency-Key` and include in body for server-side dedupe (if supported).
- Backpressure & Circuit-breaker:
- Add exponential backoff with jitter and max retry window.
- Implement a circuit-breaker that opens on consecutive failures, stops sending for a cooldown, then half-open probes.
- DLQ & Replay:
- Persist failed events (JSONL or lightweight queue) with reason and next-attempt time.
- Add a background replay worker with rate limiting and visibility into backlog.
- Metrics & Logging:
- Prometheus counters/gauges: events_generated, sent, failed, deduped, dlq_depth, circuit_state; latency histograms.
- Structured logs for failures with keys.
## Acceptance Criteria / Tests
- Under induced 5xx or timeouts, client opens breaker, stops flooding, writes to DLQ, then recovers and drains when service returns.
- Idempotent resubmissions do not create duplicates (server returns success with same id), counters reflect dedupe.
- Unit tests for backoff, breaker state transitions, DLQ persistence, and replay.
## Notes
- Keep DLQ pluggable (file-based default); allow disabling via config.

# 013 — Link SLURP Events to UCXL Decisions and DHT
- Area: `pkg/integration/slurp_events.go`, `pkg/ucxl/decision_publisher.go`, `pkg/dht/encrypted_storage.go`
- Priority: High
## Background
SLURP events currently capture HMMM discussion context but lack explicit UCXL address references and provenance links to encrypted decisions stored in DHT. This limits cross-system traceability.
## Scope / Deliverables
- Event Enrichment:
- Include UCXL address fields in all SLURP events (e.g., `ucxl_agent`, `ucxl_role`, `ucxl_project`, `ucxl_task`, and `ucxl_path` if applicable).
- Add `ucxl_reference` (full address) to event metadata.
- Decision Publication:
- On conclusive outcomes (approval/blocker/structural_change), publish a Decision via `DecisionPublisher` with a matching UCXL address.
- Store decision content in encrypted DHT (role-based) and include decision UCXL address and DHT hash in SLURP event metadata.
- Retrieval API (optional):
- Helper to fetch the latest decision for a given UCXL tuple to embed snapshot into SLURP event content.
## Acceptance Criteria / Tests
- Events produced include valid UCXL fields and a `ucxl_reference` that round-trips via `ucxl.Parse`.
- For decisions, a matching entry is stored in DHT; retrieval by address returns the same content.
- Integration test: HMMM discussion → SLURP event → DecisionPublisher called → DHT contains encrypted decision.
## Notes
- Coordinate address grammar with Issues 001 and 011; ensure alignment across modules.

# 014 — SLURP Leadership Lifecycle and Health Probes
- Area: `pkg/election/slurp_manager.go`, `pkg/health/*`, `main.go`
- Priority: Medium-High
## Background
SLURP leadership embeds into election manager but lacks fully wired start/stop runners on admin transitions, single-runner guarantees, and concrete health/readiness probes with metrics.
## Scope / Deliverables
- Lifecycle:
- Start context generation on becoming admin; stop on demotion; guard against multiple runners.
- Expose leadership state (leader id, term, since) and generation status.
- Health/Readiness:
- Add health checks for generation loop (last success time, backlog), report via health manager.
- Readiness endpoint to block traffic if generation cannot start.
- Metrics:
- Prometheus metrics for generation ticks, failures, time since last success, active tasks.
## Acceptance Criteria / Tests
- On admin change in tests, generation starts within a bounded time and stops on demotion; no concurrent runners.
- Health endpoints reflect unhealthy state when the loop is stalled; metrics increment as expected.
## Notes
- Align with Issue 005 (election heartbeat) for consistent transitions.

# 015 — Monitoring: Metrics, SLOs, and Alerts for BZZZ/UCXI/DHT/SLURP
- Area: instrumentation across services, `infrastructure/monitoring/*`
- Priority: Medium
## Background
Prometheus/Grafana/Alertmanager are provisioned, but service metrics and SLO-based alerting for critical paths are incomplete. Operators need actionable dashboards and alerts.
## Scope / Deliverables
- Instrumentation:
- Expose Prometheus metrics in BZZZ core (peer count, pubsub msgs), UCXI (req count/latency/errors by code), DHT (put/get latency, cache hits), SLURP (Issue 012 stats).
- Dashboards:
- Grafana dashboards per component with golden signals (latency, error rate, saturation, traffic) and health.
- SLOs & Alerts:
- Define SLOs (e.g., UCXI success rate ≥ 99%, DHT p95 get ≤ 300ms, peer count ≥ N) and add alert rules.
- Alerts for election churn, breaker open (SLURP), DLQ backlog growth, sandbox failures.
## Acceptance Criteria / Tests
- `curl /metrics` endpoints show component metrics; Prometheus scrapes without errors.
- Grafana dashboards render with data; alert rules fire in simulated faults (recording rules ok).
## Notes
- Keep scrape configs least-privileged; avoid secret leakage in labels.

# 016 — E2E Tests: HMMM → SLURP → UCXL Decision and Load
- Area: test harness under `test/` or `integration_test/`
- Priority: Medium
## Background
We need an end-to-end test proving HMMM discussions generate SLURP events, which in turn publish encrypted UCXL decisions to DHT, retrievable via UCXI. Also needed are load and error-injection tests.
## Scope / Deliverables
- E2E Happy Path:
- Simulate a HMMM discussion satisfying thresholds; SLURP integrator generates event with UCXL refs; DecisionPublisher stores decision; UCXI GET retrieves content.
- Load Test (lightweight):
- Batch N events with batching enabled; assert throughput, no duplicates, bounded latency; ensure breaker never opens in healthy scenario.
- Error Injection:
- Force SLURP 5xx/timeouts → verify backoff/breaker/DLQ (Issue 012) and eventual recovery.
- CI Wire-up:
- Make tests runnable in CI with mocked DHT/UCXI or local ephemeral services.
## Acceptance Criteria / Tests
- E2E test passes deterministically; artifacts (events + decisions) validate schema; UCXL addresses parse.
- Load test achieves configured throughput without error; error-injection test drains DLQ on recovery.
## Notes
- Reuse existing integration test patterns (e.g., election integration) for harness structure.

# 017 — HMMM Adapter Wiring and Tests in BZZZ
- Area: `pkg/hmmm_adapter/`, `pubsub/`, coordinator
- Priority: Medium
## Background
We need a minimal adapter that lets HMMM publish raw JSON to perissue topics using BZZZ pub/sub, plus tests. This enables perissue rooms without imposing BZZZ envelopes.
## Scope / Deliverables
- Adapter:
- Implement a small bridge with hooks to `JoinDynamicTopic(topic)` and a `PublishRaw(topic, payload)` helper.
- Path: `pkg/hmmm_adapter/adapter_stub.go` (scaffold added).
- PubSub:
- Add a `PublishRaw(topic, payload []byte) error` helper that publishes bytes without BZZZ `Message` envelope.
- Ensure `JoinDynamicTopic` idempotently joins perissue topics.
- Tests:
- Adapter unit tests (scaffold added) verifying join and publish calls.
- Optional pubsub integration test with a loopback topic.
- Integration:
- Initialize the adapter + HMMM Router in main and/or coordinator; start using `router.Publish` for HMMM messages.
## Acceptance Criteria / Tests
- `go test ./...` passes, including adapter tests.
- Perissue publish path works in a development run (seed message appears on `bzzz/meta/issue/<id>`).
## Notes
- Next issues: persistence/indexing (HMMM 004), SLURP wiring (HMMM 005).
