## Why master is red
After PRs #1592 (route-window subpath regression test) and #1595
(background/chunked index build with 503 readiness gate) were merged
together, two tests in `cmd/server/subpaths_window_test.go` started
failing on master:
```
--- FAIL: TestSubpathsHonorsTimeWindow_StoreLevel
subpaths_window_test.go:70: unbounded: expected totalPaths=2, got 0 (subpaths=[])
--- FAIL: TestSubpathsHandlerHonorsTimeWindow
subpaths_window_test.go:116: GET /api/analytics/subpaths?...: status=503 body={"error":"index loading","retryAfter":5}
```
Both branches passed in isolation; the conflict only manifested
post-merge. Reason:
- **#1592** added tests that call `store.Load()` then immediately query
`GetAnalyticsSubpathsWithWindow` / hit `/api/analytics/subpaths`.
- **#1595** moved the subpath + path-hop index builds off the critical
path of `Load()` into background goroutines, and hard-gated the
analytics handlers behind `SubpathIndexReady()` (returning 503 +
`Retry-After: 5` until the build completes).
So after `Load()` returns, `s.spIndex` is still empty for a short window
and the handler returns 503. The store-level test sees `totalPaths=0`;
the handler test sees the 503.
## Fix (test-only)
Add `store.WaitIndexesReady(5 * time.Second)` between `Load()` and the
assertions in both tests. This matches the established pattern already
used by `routes_test.go` and `repeater_enrich_recomputer_1008_test.go`.
The 503 readiness gate from #1595 is intentional production behavior and
is **not** touched. No production code is modified.
## Repro
Before:
```
$ go test ./cmd/server/ -run TestSubpaths.*Window -v -count=1
--- FAIL: TestSubpathsHonorsTimeWindow_StoreLevel (0.01s)
subpaths_window_test.go:70: unbounded: expected totalPaths=2, got 0 (subpaths=[])
--- FAIL: TestSubpathsHandlerHonorsTimeWindow (0.02s)
subpaths_window_test.go:116: GET /api/analytics/subpaths?minLen=2&maxLen=8: status=503 body={"error":"index loading","retryAfter":5}
FAIL
```
After:
```
$ go test ./cmd/server/ -run TestSubpaths.*Window -v -count=3
--- PASS: TestSubpathsHonorsTimeWindow_StoreLevel (0.01s)
--- PASS: TestSubpathsHandlerHonorsTimeWindow (0.02s)
... (x3) ...
PASS
ok github.com/corescope/server 0.097s
$ go test ./cmd/server/ -count=1 -timeout 300s
ok github.com/corescope/server 46.292s
```
## Files changed
- `cmd/server/subpaths_window_test.go` (+11 lines, test-only)
## Notes
- TDD exemption: this is a test-fix PR for a merge-conflict-induced
failure. The "failing test" already exists on master; this PR makes it
pass correctly by waiting on the readiness gate the test was previously
unaware of.
- Unblocks staging deploys.

## What
The Route Patterns chart on `/#/analytics` ignored the Time window
picker — every selection returned identical data. This PR threads
`?window=` through to the backing endpoints and the store-level
computation.
## Root cause
`cmd/server/routes.go:2065` (`handleAnalyticsSubpaths`) and
`cmd/server/routes.go:2090` (`handleAnalyticsSubpathsBulk`) never called
`ParseTimeWindow(r)`. The store-level entry points
(`GetAnalyticsSubpaths`, `GetAnalyticsSubpathsBulk`) had no window-aware
variant. The frontend (`public/analytics.js`) didn't append `&window=`
to the `/analytics/subpaths-bulk` request.
## Fix
### Backend (`cmd/server/store.go`)
Added `GetAnalyticsSubpathsWithWindow` +
`GetAnalyticsSubpathsBulkWithWindow`. Zero `TimeWindow` →
byte-equivalent to the existing fast path (no perf regression on the
default view). Non-zero window → iterate `s.packets`, filter on
`tx.FirstSeen` via `TimeWindow.Includes`, reuse `rankSubpaths`. Cached
by `(region|area|window)`.
```diff
-data := s.store.GetAnalyticsSubpaths(region, minLen, maxLen, limit)
+window := ParseTimeWindow(r)
+data := s.store.GetAnalyticsSubpathsWithWindow(region, minLen, maxLen, limit, window)
```
```diff
-results := s.store.GetAnalyticsSubpathsBulk(region, groups)
+results := s.store.GetAnalyticsSubpathsBulkWithWindow(region, groups, ParseTimeWindow(r))
```
### Frontend (`public/analytics.js`)
`renderSubpaths` now appends `&window=<value>` to the
`/analytics/subpaths-bulk` request, matching how RF / topology /
channels tabs already wire the picker.
## Before / after
```
GET /api/analytics/subpaths?window=24h → totalPaths=2 (all data — ignored window)
GET /api/analytics/subpaths?window=24h → totalPaths=1 (24h-bounded — honored)
```
## Tests
`cmd/server/subpaths_window_test.go`:
- `TestSubpathsHonorsTimeWindow_StoreLevel` — seeds a 1h-old tx with
path `[aa,bb]` + a 30d-old tx with path `[cc,dd]`; asserts the unbounded
call sees both and the 24h-windowed call sees only the recent one.
- `TestSubpathsHandlerHonorsTimeWindow` — same scenario via the HTTP
handlers for `/api/analytics/subpaths` and
`/api/analytics/subpaths-bulk`.
TDD: red commit `eefc27d3` (test fails on assertion with stub that
ignores window), green commit `4c4c45d0` (implementation makes it pass).
Full `go test ./...` in `cmd/server` green locally (~47s).
## Performance
Default view (no window selected) is unchanged — `window.IsZero()`
short-circuits to the existing precomputed-index hot path. Windowed view
is O(N_tx · path²), same complexity as the existing region-filtered slow
path. Results cached per `(region|area|window)`.
Closes#1217
