## Summary
Mirrors the distance-index lazy pattern (#1011): the subpath and
path-hop index builds are no longer part of `Load()`'s synchronous
critical section. They now run in **two parallel background goroutines**
kicked off after `s.loaded = true`, so HTTP comes up immediately even at
Cascadia scale (5M observations, previously ~60s blocked on these two
builds inside `Load()` under `s.mu`).
Fixes #1008.
## Approach
Two new `atomic.Bool` fields on `PacketStore` (`subpathReady`,
`pathHopReady`) plus a one-shot broadcast channel (`indexReadyChan`) for
waiters. `Load()` removes the synchronous `s.buildSubpathIndex()` /
`s.buildPathHopIndex()` calls and instead kicks
`s.startBackgroundIndexBuilds()` right before returning. That function
spawns **two independent goroutines** (review m7), one per index. Each
goroutine:
1. acquires `s.mu.Lock()` (blocks until `Load()`'s deferred Unlock
fires),
2. runs its builder, releases the lock, stores its `ready = true`,
3. closes the broadcast channel if both flags are now true,
4. logs `[startup] index build complete: subpath (Xs)` (or pathHop).
Analytics handlers whose entire response IS the index aggregate —
`/api/analytics/subpaths`, `/api/analytics/subpaths-bulk`,
`/api/analytics/subpath-detail`, `/api/nodes/{pubkey}/paths` — gate
reads behind the corresponding atomic and respond with `503 Service
Unavailable`, `Retry-After: 5`, body `{"error":"index
loading","retryAfter":5}` until the build completes — matching the
triage spec.
### Handler scope (review M2)
A second class of handlers also touches these indexes — `/api/nodes`,
`/api/nodes/{pubkey}`, the `GetRepeaterRelayInfoMap` /
`GetRepeaterUsefulnessScoreMap` / `GetBridgeScore` enrichment helpers,
and `repeater_liveness` / `repeater_usefulness`. These are
**intentionally NOT 503-gated**: they expose the index via optional
enrichment fields that callers already treat as "may be empty", and
503-ing the SPA bootstrap to wait for an index that only affects
relay-activity badges would be a worse UX than a 30–60s window of "—"
values. The rationale is documented in the package doc-comment at the
top of `index_ready_1008.go`.
The recomputer's synchronous prewarm path
(`StartRepeaterEnrichmentRecomputer`) gates on `WaitIndexesReady(60s)`
(review M1) so it never snapshots an empty `byPathHop` into
`s.repeaterRelayCache`; on timeout it skips the prewarm and lets the
5-minute ticker pick up the populated index.
## Concurrency safety
Each build goroutine acquires `s.mu.Lock()` before calling the existing
`buildSubpathIndex()` / `buildPathHopIndex()` helpers, which replace
`s.spIndex` / `s.spTxIndex` / `s.byPathHop` with freshly-allocated maps.
Visibility of the populated maps to handlers that observe
`Ready()==true` is established by Go 1.19+ sync/atomic acquire-release
semantics: the atomic store of `true` happens-after `s.mu.Unlock()`, and
the handler's atomic load synchronizes-with that store. The handler's
subsequent `s.mu.RLock` serializes against concurrent ingest writers,
not against the builder.
The existing `main.go` boot sequence does not start ingest goroutines
until after `store.Load()` returns and graph init completes, so the
brief window between `Load()` returning and the two goroutines acquiring
`s.mu` does not race with concurrent ingest writes.
## TDD: red → green
- **Red** commit `63e79e11`: `cmd/server/index_ready_1008_test.go` adds
four assertions; `cmd/server/index_ready_1008.go` adds compile-only
stubs returning `true` so the tests fail on assertions, not build
errors.
- **Green** commit `fb1d22b0`: implements the real atomic gates, the
background goroutine, and the four handler 503 branches; also updates
four existing tests that read indexes directly post-`Load()` to call
`store.WaitIndexesReady(5s)` first.
- **Race-fix commit `b77d56eb`** (review m8 — test-infra exemption):
adds `WaitIndexesReady` calls in test helpers/setup paths so the race
detector no longer flags the read-after-Load() pattern in existing
tests. Per AGENTS.md, race-detector flakes are observable evidence (test
crashes under `-race`) and qualify for the test-infra exemption from the
TDD red-commit requirement; no behavior change in production code.
- **Polish round 2 — M1 red `408c7462` / green `85e82c8a`**:
`TestIssue1008_M1_PrewarmWaitsForIndexes` asserts the recomputer prewarm
SKIPs when indexes are not ready. Red commit adds the assertion + a stub
`repeaterEnrichmentPrewarmWait` var; green commit wires
`WaitIndexesReady` into the prewarm path and adds the handler-scope docs
for M2.
- **Polish round 2 — minor cleanups `fd089bd0`** (m3..m7): chunk-loader
wires `markIndexesReadySync`, memory-model comment rewritten to cite
acquire-release, sentinel deleted, polling replaced with a broadcast
channel, two parallel goroutines for the builds.
`TestIssue1008_m7_BothFlagsSetAfterParallelStart` covers the parallel
path.
## Reproduction
```
git fetch origin fix/issue-1008
git checkout 63e79e11 # red commit
cd cmd/server && go test -run TestIssue1008_ -count=1 . # FAILs
git checkout fix/issue-1008 # latest green
cd cmd/server && go test -run TestIssue1008 -count=1 -race . # all pass
cd cmd/server && go test -count=1 -race -short ./... # full suite ok
```
## Files changed
| file | role |
|---|---|
| `cmd/server/store.go` | atomic.Bool fields + indexReadyChan broadcast
field; remove sync build calls in Load(); kick goroutines; wire
markIndexesReadySync from chunk loader |
| `cmd/server/index_ready_1008.go` | ready flags, two-goroutine
background builds, 503 helper, channel-based WaitIndexesReady,
handler-scope docs |
| `cmd/server/index_ready_1008_test.go` | red-commit contract tests +
parallel-start assertion |
| `cmd/server/repeater_enrich_recomputer.go` | gate prewarm on
WaitIndexesReady (M1) |
| `cmd/server/repeater_enrich_recomputer_1008_test.go` | M1 red+green
assertions |
| `cmd/server/routes.go` | 503 gate on 4 analytics handlers |
| `cmd/server/routes_test.go` | setup helpers wait for ready; collision
test waits |
| `cmd/server/coverage_test.go` | three tests wait for ready before
reading indexes |
## Out of scope
- Distance index (already deferred in #1011) — untouched.
- The `pickBestObservation` + `indexByNode` per-tx loop in `Load()` —
kept synchronous per triage Findings (ordering-sensitive,
contiguous-memory, fast).

// Retry-After: 5.
|
