Analytics review fixes:
- Store Twitter analytics coverage as discrete intervals instead of a single
contiguous window so disjoint fetch ranges no longer mask inner gaps as
covered (fetch per uncovered range, add gap regression tests)
- Compute real AvgEngagement/Correlation in getEngagementDrivers instead of
all-zero placeholders
- Make parseAnalyticsTimeRange surface invalid timestamps, cap merged analytics
posts at limit, and normalize sentiment by timestamped posts only
- gofmt: fix misalignment in config.go and types.go
- Include Twitter in the default aggregate analytics scope; its API costs are
passed to the caller through paid tool pricing
x402 cost passing:
- computeTwitterStyleProfileCost now charges base cost ($0.10) + user lookup
($0.01) + $0.005 per Twitter post, guaranteeing the charge always clears the
underlying API cost (never break-even or loss)
- Return a $-prefixed dollar string for the settlement override, fixing the
previously off-by-factor-100 raw-atomic-unit amount
- Raise getStyleProfile base registration to $0.36 to authorize the max Twitter
charge
- Add tests for the cost formula, profitable floor, and dollar formatting
- schema: add IF NOT EXISTS to CREATE TABLE/INDEX for idempotent migrations
- store: regenerate with sqlc v1.31.1 (adds UserStylePost, interface{} for Embedding)
- webhook: minor formatting cleanup
- Add MATRIX_WEBHOOK_URL and MATRIX_SERVER_ID config fields (optional, defaults to hostname)
- Create internal/server/webhook.go: WebhookSender with exponential backoff retry (5 attempts),
first/last attempt logging, non-blocking goroutine integration
- Wire webhook into OnAfterSettle callback in server.go (goroutine, fire-and-forget)
- Migrate all persistent interface{} to any (Go 1.25.4 convention):
db.go: ...any in DBTX interface
models.go: Embedding any
FindSimilarUsers.sql.go: QueryEmbedding any, Embedding any
UpsertStyleProfiles.sql.go: Embedding any
- Migrate server.go map[string]interface{} to map[string]any in webhook payload
- Add TestStoreSaveTransaction integration test (skipped without TEST_DATABASE_URL)
- Add TestSettleHook unit test for param mapping
- Add missing ModelVersion, SchemaVersion, AlgorithmVersion fields to UserStyleProfile struct
- Update sqlc version from v1.30.0 to v1.31.1 in db.go and models.go
- Fix any/interface{} type consistency in db.go
