Calendar and climbing queries were rebuilding complete provider payloads for historical activity groups before date filtering. Production execution plans spent 12–14 seconds in that JSON aggregation, alongside connection-acquisition failures and mobile HTTP 524 responses.

Pass only the four metadata fields consumed by origin resolution, preserving full stored/public raw payloads and all origin outputs. Install the same canonical view through forward migration 0161. This composes with main's migration 0160, retaining its per-selected-group origin lookup. Earlier read-only comparisons of metadata narrowing alone reduced calendar execution from 13.92 to 1.24 seconds and climbing progression from 12.20 to 1.19 seconds; those timings do not measure the final combination. Production deployment remains pending.

Validation:

  • Deterministic real-Postgres regression failed before the fix at 65,752 resolver-input bytes for a 64 KiB vendor fixture; it passes below 1,024 bytes after the fix while preserving complete public raw data.
  • After syncing main, 109 focused integration tests pass, including main's two scoping regressions, the input-size regression, and ten all-column metadata parity cases.
  • Merged full unit/mobile suite: 20,459 passed, 19 skipped. Full lint, spelling and root/server/web typechecks pass.
  • Actual local migration path, new-migration SQLFluff/policy, canonical/migration equality, and all 45 empty-source dbt models pass.

Local validation limitation: the activity visibility consistency suite failed ClickHouse fixture setup with Code 241 at its local memory ceiling, including in an isolated diagnostic run. No limits, retries, timeouts, or query settings were changed. The original hosted CI passed all four integration shards; fresh hosted CI must cover the composition with main. The incident baseline and query trace record the exact evidence and follow-up.

Summary by Sourcery

Bound activity origin metadata aggregation to reduce calendar and climbing query costs while preserving origin resolution behavior and complete public activity payloads.

Bug Fixes:

  • Prevent expensive historical activity queries from aggregating complete provider payloads before date filtering by bounding origin-resolution metadata to the four fields it consumes.
  • Install the corrected activity view through forward migration 0161 while preserving public raw payloads and existing origin outputs.

Enhancements:

  • Retain main's per-selected-group origin lookup while combining it with bounded resolver input construction.
  • Document the production query incident, performance evidence, validation boundaries, and follow-up runbook guidance.

Documentation:

  • Add a detailed trace of the calendar and climbing query incident, diagnosis, proposed correction, validation, and remaining deployment risks.
  • Record the incident baseline, local validation limitations, and merge preparation in the production incident documentation.

Tests:

  • Add real-Postgres regressions covering resolver input size, complete public raw data, and origin behavior across metadata conflicts, missing values, SQL nulls, and JSON nulls.
  • Validate the combined scoped-origin and bounded-input changes across focused integration, unit/mobile, migration, lint, typecheck, and analytics model checks.

Summary by CodeRabbit

  • Bug Fixes
    • Reduced the amount of activity metadata processed when resolving activity origins, which can help prevent slow responses and timeouts in calendar and climbing views.
  • Documentation
    • Added reports documenting the performance investigation, validation findings, and remaining follow-up work.

Keep full vendor payloads out of provenance aggregation while retaining
the metadata used by origin resolution and complete public raw data.

Walkthrough

Migration 0161 defines fitness.v_activity and resolves origin provenance using selected activity members. The view limits raw metadata passed to the resolver to four fields. Integration tests check origin results and input size. Documentation records incident measurements, validation, and outstanding deployment status.

Changes: Activity origin view

Layer / File(s) Summary
Activity view and resolver input
drizzle/0161_bound_activity_origin_input.sql, drizzle/_views/01_v_activity.sql, drizzle/meta/_journal.json
Migration 0161 defines the activity view and its revision ranking, tombstone handling, grouping, and origin provenance. The resolver receives only sourceBundle, device_name, platform, and deviceType in raw. The migration journal records the new migration.
Origin integration coverage
src/db/activity-origin.integration.test.ts
Tests cover origin results for transfer evidence, missing or JSON-null metadata, and conflicting source bundles. A large-payload test checks that the resolver input is under 1,024 bytes.
Incident record and validation
docs/performance/calendar-climbing-query-trace-2026-10-23.md, docs/production-incident-baseline.md, cspell.json
The documents record incident observations, query measurements, validation results, unresolved test setup failures, and outstanding deployment and post-deployment measurements. The spelling dictionary adds functiondef.

Explanation

The title "[db] Bound activity origin metadata" uses the required area prefix, is under 70 characters, has no trailing punctuation, and names the main change: origin-resolution input is bounded to the four consumed metadata fields. The objectives describe this same change. The title does not state the performance purpose, but it is not misleading.

Reviewer's Guide

This PR addresses slow calendar and climbing queries by narrowing activity-origin resolver inputs to four required metadata fields, installs the identical change through migration 0160, adds comprehensive Postgres parity and size-bound regression coverage, and documents the incident evidence and validation limits. Read-only measurements indicate roughly 10–12x faster query execution, while production deployment and five ClickHouse visibility assertions remain outstanding.

Summary & Evaluation: LGTM

The changes address the query latency and connection acquisition timeout bottleneck observed during calendar and climbing queries by bounding the metadata passed to fitness.resolve_activity_origin inside fitness.v_activity.

Findings & Verification

  1. Origin Input Bounding (01_v_activity.sql & 0160_bound_activity_origin_input.sql):
    • The view now aggregates only the four raw JSON keys (sourceBundle, device_name, platform, deviceType) evaluated by fitness.resolve_activity_origin and fitness.activity_copy_identity, instead of aggregating the entire stored vendor payload.
    • The canonical view definition and the forward migration file 0160_bound_activity_origin_input.sql are byte-identical and properly registered in drizzle/meta/_journal.json.
    • The final view output v_activity.raw continues to expose the full merged.raw (derived directly from ranked.raw), ensuring no regression or payload loss in public activity responses.
  2. Regression & Parity Testing (activity-origin.integration.test.ts):
    • Verifies resolver payload size bounds (<1 KiB) against a large vendor payload (64 KiB), while verifying full raw retention on v_activity.
    • Covers 10 distinct metadata configurations (source bundle, device name, copy identity, null handling, missing fields).
    • Test harness cleans up auxiliary tables and restores original function definitions in finally blocks.
  3. Documentation & Traceability:
    • Trace documentation in docs/performance/calendar-climbing-query-trace-2026-10-23.md and baseline incident entries in docs/production-incident-baseline.md accurately record the query plans, latency reduction (from ~13.9s/12.2s to ~1.2s), reproduction evidence, and follow-up items per repository guidelines.

Code is sound, safe, and ready to merge.

Addressed the title-prefix warning in #3063 (comment): the title is now [db] Bound activity origin metadata, matching the area-prefix convention in .coderabbit.yaml. Bound is already an imperative verb, so that wording is retained.
