…ibutes error_events_mv took the exception type, message and stacktrace from the first OTel `exception` span event alone, then fell through to StatusMessage and the literal 'Unknown Error'. Cloudflare's native Workers tracing records no span events and no status description — a custom span can only setAttribute() — so every error span it exported hashed to one "Unknown Error" issue per service, whatever was thrown. The shared error-events SELECT now resolves the source in order: the event, taken verbatim as before; the same three keys as `exception.*` span attributes; semconv `error.type` / `error.message`; then StatusMessage. The message signature and display label are cut from `_msgText`, which is StatusMessage whenever it is set or an event exists and the attribute message only for an event-less span with none, so the only rows whose hash changes are the ones that shared the "Unknown Error" bucket. The 0016 4xx guard keeps dropping a client span whose only error.type is the bare status code, which HTTP semconv sets on any non-2xx response. Migration 0024 recreates both error-events views (no backfill: error_events keeps no span attributes to re-derive from, and recomputing FingerprintHash would re-bucket every issue). The local chDB schema moves to v14 with a matching edge. `resolveErrorSource` mirrors the precedence in fingerprint.ts, and a ClickHouse e2e seeds a workers-observability span carrying only attributes through the real migration set and asserts the derived label on both target tables.
Main landed 0024_ai_trace_index and local schema v14 (#692) in the meantime. The error-events attribute fallback moves to ClickHouse migration 0025 and the local chDB edge to v14 -> v15; the generated schema, local DDL snapshot, insert mappings and Tinybird manifest are regenerated on the merged tree.
Main landed 0025_commit_sha_vcs_revision and local schema v15 (#749). The error-events attribute fallback moves to ClickHouse migration 0026 and the local chDB edge to v15 -> v16; generated artifacts regenerated on the merged tree.
Main landed 0026_ai_trace_index_filter_columns and local schema v16 (#738). The error-events attribute fallback moves to ClickHouse migration 0027 and the local chDB edge to v16 -> v17; generated artifacts regenerated on the merged tree.
The only conflict was the generated Tinybird manifest, resolved by regenerating it from the merged sources. Migration numbering is unaffected: main is still at 0026 / local v16, so this change stays 0027 / v16 -> v17, and 0027's frozen DDL still matches the regenerated snapshot byte for byte. Main's "fix tinybird migration" documents that Tinybird treats a changed MV node as a reason to rebuild the target by replaying its source. Both error-events views change their SELECT here, and their source is `traces`, which keeps 30 days against the targets' 90. A replay would therefore drop two months of occurrences AND recompute FingerprintHash for every stored row, re-bucketing every triaged issue — precisely what 0027 refuses to do. Both views now carry `deploymentMethod: "alter"`, which swaps the SQL at promotion with no data movement, matching the migration's forward-only contract. It is Tinybird deploy metadata, not DDL: the local structural schema digest is unchanged, so no new schema bump.
All four conflicts were generated files, and both sides had only changed the project-revision hash: main regenerated them in 3cdb22a without this branch's `deploymentMethod` addition. Resolved by regenerating from the merged sources, which is the only way the hash can be correct. Main's own changes here are infra/ACM only and touch no warehouse source. Numbering is unaffected — main is still at 0026 / local v16, so this stays 0027 / v16 -> v17 — and 0027's frozen DDL still matches the regenerated snapshot byte for byte.
…t log Main's org-wide audit log (#683) took ClickHouse migration 0027 and local schema v17, the numbers this branch held. Resolved by taking main's side on every conflicted generated and bump-managed file, then re-applying this change on top: the migration is now 0028 and the local edge v17 -> v18. 0028's frozen DDL was re-emitted from the regenerated snapshot and verified to match it byte for byte, so it carries main's audit-log tables and this branch's `deploymentMethod: "alter"` on both error-events views.
…events Main's product-events-from-traces change (#710) took ClickHouse migration 0028 and local schema v18, the numbers this branch held. Same resolution as the previous two collisions: take main's side on every conflicted generated and bump-managed file, then re-apply this change on top. The migration is now 0029 and the local edge v18 -> v19. 0029's frozen DDL was re-emitted from the regenerated snapshot and verified against it byte for byte.
…e conventions Main's ai-trace-index usage conventions (#766) took ClickHouse migration 0029 and local schema v19, the numbers this branch held. Same resolution as the previous three collisions: take main's side on every conflicted generated and bump-managed file, then re-apply this change on top. The migration is now 0030 and the local edge v19 -> v20. 0030's frozen DDL was re-emitted from the regenerated snapshot and verified against it byte for byte.
No renumbering this time — main is still at 0029 / local v19, so this change stays 0030 / v19 -> v20. The only conflict was the migrations index test, where main reflowed the version-list literal while this branch appended 30 to it; kept main's formatting with the entry.

- Around line 750-765: Update the _useAttrs logic in both error_events_mv and
error_events_by_time_mv to depend only on _ei = 0, preserving span attribute
precedence when no exception event exists. Make _exMsg fall back to
StatusMessage only when both exception.message and error.message are empty, then
regenerate both views.

Error spans without an exception event or status message currently share an
Unknown Errorfingerprint per service. Fill those missing details fromexception.*span attributes, thenerror.type/error.message.Spans with an exception event (including empty event fields) or a nonempty
StatusMessageretain all existing fingerprint inputs and display fields. Attribute fallback cannot split an already-labelled issue. The bare HTTP 4xx filter stays in place, while attribute-only spans carrying an exception type remain eligible.The shared SQL owns source resolution; the duplicate TypeScript resolver has been removed. Migration 0030 and local schema v19 → v20 replace the two views without rewriting stored occurrences.
FINGERPRINT_VERSIONremains unchanged because unaffected issues keep receiving their existing hashes. Tinybird usesdeploymentMethod: "alter"to preserve target history. Generated schemas, insert mappings, manifests, and local identities are synchronized.Validation:
The exporter fixtures are synthetic, not captured Cloudflare OTLP payloads. This establishes warehouse behavior, not Cloudflare export compatibility. Landing traces remain disabled. The native local-store shell probe and repository-wide tests were not run.
