Ablation (PHASE2-FINDINGS.md) attributed the memory win to the
serverExternalPackages line and the integrations barrel diet. These three
measured at exactly zero and were most of the file churn, so they go:
next-cache-handler: orphaned. cacheHandlers and cacheComponents are both
already gone from next.config.ts and nothing imported the package — it
was reachable only through a stale dependency entry.
cache-tags / cache-invalidation: there is no "use cache", cacheTag,
cacheLife or unstable_cache anywhere in app source, so revalidateTag was
firing on tags nothing registers, with no handler to receive them, inside
a catch that swallowed the resulting out-of-scope error. Removing the
calls also removed the SELECTs that existed only to supply a board name
or member list to them, so board.ts, group.ts, user.ts, serverSettings.ts,
section-router.ts and change-search-preferences.ts return to the
merge-base exactly. The live in-process integration data cache is
untouched.
Redis 6 -> 2 client consolidation: no measurable effect at idle (139.3 vs
139.2 MiB) or under load. Reverted, but the pubSub:last:* TTL is kept —
that one is an unbounded-growth fix, not a consolidation.

- Replace `as any` casts in integration-test-connection.spec.ts with
Pick<Integration, "testConnectionAsync"> + mockResolvedValue
- build-compare.sh: split local declarations (SC2318), clean .next
between builds with --force, add EXIT trap for safe stash/cleanup
Revert layout.tsx, _layout-creator.tsx, manage/layout.tsx,
_theme.tsx, _creator.tsx, mantine.tsx, and login/page.tsx
to origin/dev — the Suspense provider splits caused
"EditMode is required", stream close, and React #419 errors.
Also remove cacheComponents/cacheHandlers from next.config.ts
(incompatible with auth/i18n/dynamic rendering) and fix
Boolean() truthy bug in Redis connection.
The barrel no longer exports PiHoleIntegrationV6 after the dynamic
import refactor. The mock only needs testConnectionAsync, so a type
cast is sufficient.
- BoardLayoutFallback: use HomarrLogoWithTitle (no board context required)
- integration-data-cache: guard cache.set with placeholder identity to
prevent stale write-back after invalidation + test
- next-cache-handler: memoize the promise (not resolved handler) to
prevent concurrent Redis connections
- redis-handler: tee ReadableStream before consuming in set(), hand fresh
branch to each get() caller
- redis-handler: base64-encode body instead of number[] (3-4x smaller)
Merge origin/dev to pick up service isolation (concurrently dev script,
turbopack aliases, instrumentation simplification), PostHog analytics,
color scheme, and other dev improvements while preserving all Phase 1
performance work (Suspense boundaries, cache components, Redis handler,
integration barrel diet, cache invalidation).
- Redis get() rejects legacy expire=0 entries and cleans them up
- transferOwnership invalidates previous owner in addition to new
- SVG regex uses non-greedy match and handles self-closing <svg />
- SVG fallback returns empty string instead of HTML wrapper
- Memory channel comment: FIFO eviction, not timestamp-based
- Fix integration data cache: check pending promise before TTL to
prevent returning undefined on concurrent cold-cache access
- Add concurrent-miss test (two parallel callers, one fetch)
- SVG sanitizer: extract <svg> from DOMPurify output to strip
residual HTML wrapper
- Narrow safeRevalidateTag catch: log unexpected errors, silence only
known "outside request scope" messages
- Run oxfmt across all packages (206 files formatted)
- Fix critical bug: tag expiration comparison was inverted (< should be >)
in Redis cache handler, which would prevent revalidateTag from clearing
stale entries
- Pass board name to invalidateBoardCache in saveItemOptions
- Add clarifying comment about two-tier invalidation helpers
- Remove all concrete integration class re-exports from barrel
- Replace instanceof check with kind check in health-monitoring
- Document cache invalidation as preparatory (cacheTag follow-up)
- Pass board.name to all invalidateBoardCache calls (permission mutations)
- Align integration create invalidation with update/delete
- Add initial-fetch-failure test for integration-data-cache
- Expand SVG XSS test corpus (javascript:, xlink:href, @import, onbegin)
- Forbid <style> tags in SVG sanitizer to prevent CSS injection
- Fix duplicate export in packages/common/src/index.ts
