feat(phase6a-v1.2): dual-mode custom-event enrichment (v1.0 + v2.0 aliases)
- Prisma: posthog_person_cache (24h TTL), posthog_group_cache, session_custom_events
- SessionMeta: +posthogDistinctId, +groupKey, +customEventCount
- PostHog client: listSessionEvents, getPerson, getGroup
- posthog-cache.ts: cache-with-stale-refresh for person + group properties
- event-taxonomy.ts: dual-mode alias map (vin_decoded↔vin_decode_initiated,
vin_decode_success↔vin_decode_succeeded, vin_decode_error↔vin_decode_failed,
payment_success↔payment_succeeded). 56 tracked event names total.
- enrich.ts: per-session custom events fetch, persist to session_custom_events,
attach user_properties + group_properties via cache.
- tagger.ts: 14 new custom-event tags
(vin_decode_fail_pattern, provider_reliability_issue, payment_friction,
payment_ui_silent_failure (P0), payment_failed_session, checkout_abandonment,
downgrade_pending, compatibility_quality_gap, parts_export_abandoned,
search_validation_friction, onboarding_stuck, upgrade_hesitation,
power_user_path, at_risk_active_session, provider_mismatch,
api_key_friction, webhook_setup_struggle); group-context priority bump.
- heuristic.ts: customEventPromoteReasons() — 10 custom-event promote signals.
- compress.ts: merge_rrweb_and_custom_events interleaving with ⤷ EVENT: prefix,
±1.5s grouping, standalone flush for events with no nearby rrweb. Adds
company_context header line; key_events lists top-5 custom event counts.
- /insights page: +Events column. /insights/sessions/[id]: collapsible custom
events table + group key display.
Graceful: when Sase.tr emits 0 custom events the pipeline falls back to
rrweb-only tagging from Phase 6a v1.1.
PRD: behavioral-insight-pipeline-prd-1.md (v1.2),
sase-posthog-events-prd.md (Sase.tr-side, separate codebase).
