Merged 10 upstream commits (MemTable, read-your-writes tests, feed endpoint,
security hardening, signed assertions, source registry, dashboard enhancements)
and fixed all test failures across the full workspace (2656/2656 passing).
Key fixes:
- fix(cluster): DashMap deadlock in swim.rs suspect_node/fail_node/alive_node
- DashMap::get_mut RefMut + iter() on same map = non-reentrant write lock deadlock
- Fix: extract clone in scoped block to drop RefMut before calling update_node_gauges()
- 6 previously-hanging SWIM tests now pass in <2s
- fix(sim): replace background-task+polling ingestion with synchronous process_pending()
- smoke_high_volume_simulation was CPU-starved under 2656 parallel tests
- Removed ingestor.start() + wait_until_ingested() pattern throughout sim
- All arena functions now call ingestor.process_pending() directly (deterministic)
- fix(test): v2 signature helper used wrong hash (rkyv vs canonical compute_content_hash_v2)
- fix(test): quota test signed "test" but v1 requires "subject:predicate" format
- fix(test): http_validation now accepts 400 for valid-format-but-invalid-crypto hex
- fix(test): scale_adaptive micro tier assertions updated (auto_promote upstream change)
- config: add nextest.toml with slow-timeout for background-task-tests group

- Update Go SDK RegisterSourceRequest with Content field
- FCM pipeline extracts PDF text via pdftotext and passes to registration
- Dashboard impact panel fetches and displays source content with expand/collapse
- Add feed endpoint, dashboard feed panel, and signed assertion support
- Update data-structures.md, API docs, and storage docs

Declarative extractors in separate .toml files under .aphoria/extractors/ were
silently ignored because config loading only parsed the main config.toml. Now
from_file() scans the extractors directory after loading the main config and
merges any [[extractors.declarative]] definitions found in .toml files. Invalid
files produce warnings but don't fail the load. Also includes show_observations
field additions to scan args and removes unused import.

Enterprise Features:
- Hosted mode with remote sync for team pattern aggregation
- Community sharing with privacy-preserving anonymization
- LLM-based semantic claim extraction with Gemini integration
- Pattern learning with promotion to declarative extractors
- High-entropy secrets extractor with configurable thresholds
- Auth bypass and insecure cookies extractors
Module Refactoring:
- Split oversized files to comply with 500-line limit
- Config split: types/core.rs, types/extractors.rs, types/hosted.rs, etc.
- Handlers split: scan.rs, policy.rs, report.rs modules
- Extractors split: declarative/, high_entropy_secrets/, insecure_cookies/
- Learning split: store modules with metrics and persistence
SDK & Ontology:
- stemedb-ontology SDK with fluent builders and StemeDB client
- Pharma domain extractors for FDA Orange Book data
- Consumer health UAT test infrastructure
Code Quality:
- Fixed clippy warnings (needless_borrows_for_generic_args)
- Added KVStore trait imports where needed
- Fixed utoipa path re-exports for OpenAPI docs

Key changes:
- Fix Ingestor background task to release lock per iteration, preventing
deadlock when process_pending() needs the lock during shutdown
- Add blessed assertion predicate index and fetch_blessed_assertions()
for policy export workflows in Aphoria
- Add patent documentation (markdown + Word exports) for probabilistic
knowledge graph system
- Update community scripts for claim extraction pipeline

Content Defense (Phase 7):
- Add SimilarityIndex with MinHash/LSH for near-duplicate detection
- Add QuarantineStore for flagged assertions awaiting admin review
- Add CircuitBreakerStore for per-agent circuit breaker state
- Add ContentDefenseLayer for ingestion pipeline integration
- Add API endpoints for quarantine and circuit breaker management
- Add research module with gap detection and documentation fetching
Code Structure Improvements:
- Extract research CLI commands to research_commands.rs
- Extract API routers to routers.rs module
- Extract key_codec extraction functions to separate module
- Extract test modules to separate files across multiple crates
- All files now under 500 line limit per pre-commit hook

Add CRC32C checksums to WAL record format (v2), implement crash recovery
with automatic truncation of corrupt records, add feature-gated group commit
buffer for batched fsync under concurrent load, and implement log rotation
via segment files with global offset addressing.
Key changes:
- Record format v2: [len:u32][crc32c:u32][blake3:32][payload:N]
- recover_file() scans and truncates corrupt tail records
- GroupCommitBuffer batches fsync via MPSC channel (tokio feature gate)
- SegmentManager with binary search resolution and cursor-based cleanup
- Journal::read() auto-refreshes segments on miss for writer/reader split
- Split recovery.rs and key_codec.rs into directory modules for 500-line max

- Add Layered() method to Go SDK for per-source-class consensus queries
- Add LayeredQueryParams, LayeredResult, TierResolution types to Go SDK
- Create conflict example demonstrating Skeptic and Layered endpoints
- Update quickstart.md with sections 6 (conflict detection) and 7 (authority tiers)
- Remove tracked Go binary and add data/ to .gitignore
The new quickstart sections demonstrate Episteme's differentiating features:
- Skeptic endpoint shows "Trust but Verify" conflict analysis
- Layered endpoint shows per-tier resolution (Clinical vs Anecdotal)
Note: Pre-existing large files flagged by pre-commit hook (technical debt from prior sessions)

Phase 1 delivers the complete durability and storage layer:
- WAL with crash recovery: Append-only journal with BLAKE3 checksums,
fsync guarantees, and proper seek-to-EOF on reopen
- Storage engine: sled-backed KVStore with scan_prefix for range queries
- Content-addressed storage: H:{hash}, V:{hash}, E:{hash} key patterns
- Ingestor: Background worker tailing WAL, writing to KV with 8-byte
aligned record headers for rkyv zero-copy deserialization
- Comprehensive tests: 31 tests covering crash recovery, round-trips,
and multi-cycle durability
New crates: stemedb-wal, stemedb-storage, stemedb-ingest
