## Summary Fixes #303 — Repeater hash stats now reflect the **latest advert** instead of the historical mode (most frequent). When a node is reconfigured (e.g. from 1-byte to 2-byte hash size), the analytics and node detail pages now show the updated value immediately after the next advert is received. ## Changes ### cmd/server/store.go 1. **computeNodeHashSizeInfo** — Changed hash size determination from statistical mode to latest advert. The most recent advert in chronological order now determines hash_size. The hash_sizes_seen and hash_size_inconsistent tracking is preserved for multi-byte analytics. 2. **computeAnalyticsHashSizes** — Two fixes: - **yNode keyed by pubKey** instead of name, so same-name nodes with different public keys are counted separately in distributionByRepeaters. - **Zero-hop adverts included** — advert originator tracking now happens before the hops check, so zero-hop adverts contribute to per-node stats. ### cmd/server/routes_test.go Added 4 new tests: - TestGetNodeHashSizeInfoLatestWins — 4 historical 1-byte adverts + 1 recent 2-byte advert → hash size should be 2 (not 1 from mode) - TestGetNodeHashSizeInfoNoAdverts — node with no ADVERT packets → graceful nil, no crash - TestAnalyticsHashSizeSameNameDifferentPubkey — two nodes named "SameName" with different pubkeys → counted as 2 separate entries - Updated TestGetNodeHashSizeInfoDominant comment to reflect new behavior ## Context Community report from contributor @kizniche: after reconfiguring a repeater from 1-byte to 2-byte hash and sending a flood advert, the analytics page still showed 1-byte. Root cause was the mode-based computation which required many new adverts to shift the majority. The upstream firmware bug causing stale path bytes (meshcore-dev/MeshCore#2154) has been fixed, making the latest advert reliable. ## Testing - `go vet ./...` — clean - `go test ./... -count=1` — all tests pass (including 4 new ones) - `cmd/ingestor` tests — pass --------- Co-authored-by: Kpa-clawbot <259247574+Kpa-clawbot@users.noreply.github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
