pulse-triage[bot] 3b91896371 fix(api): isolate tenant resource store construction
Cold resource store construction held the shared cache mutex and delayed unrelated tenants, including cache hits. A bounded API measurement found 480ms p95 cache-hit mutex wait, while a synthetic blocked constructor reproduced the coordination defect independently of storage internals.

Deduplicate construction per tenant outside the cache mutex, and coordinate eviction with in-flight opens. Add synthetic regressions for unrelated tenants, same-tenant deduplication, retry after failure and close ordering. The resource API race suite passes. This does not establish the cause of the historical release stress failure or qualify a release.

Change-source: pulse-maintainer
Contract-Neutral: Internal tenant-store lock scheduling repair only; routes, payloads, authorization, tenant keys, storage format and eviction semantics are unchanged. Existing race-tested API coordination regressions establish deduplication, retry and close ordering; no frontend surface changes.

Internal API Package

This directory contains the API server implementation for Pulse.

Important Note About frontend-modern/

The frontend-modern/ subdirectory that appears here is:

  • AUTO-GENERATED during builds
  • NOT the source code - just a build artifact
  • IN .gitignore - never committed
  • REQUIRED BY GO - The embed directive needs it here

Frontend Development Location

👉 Edit frontend files at: ${PULSE_REPOS_DIR}/pulse/frontend-modern/src/

Why This Structure?

Go's //go:embed directive has limitations:

  1. Cannot use ../ paths to access parent directories
  2. Cannot follow symbolic links
  3. Must embed files within the Go module

This is a known Go limitation and our structure works around it.
