feat(observers): latest /neighbors report on the observers list and page (#2270, #2271) (#2300)
Closes #2270, closes #2271. The ingestor took only the confirmed region scopes out of an observer's `/neighbors` report (#1865) and dropped the rest. Nothing could therefore say when an observer last reported, or whom it heard. ## Ingestor `observer_neighbor_reports` (created in `dbschema.Apply`) keeps the latest report of each observer, one row per observer, replaced by every live report. The report is unauthenticated, so `neighbors[]` is stored sanitised: - only 64-hex keys - `snr` and `heard_secs_ago` finite and in range - `status` limited to `[a-z_]` - `scopes` clamped - at most 500 rows `total_neighbors` is believed only when it is not below the number of rows that arrived. A **retained replay** only fills a missing row, and it is dated by the report's own `timestamp`. After an ingestor restart, a long-dead observer therefore does not look as if it just reported. ## API The table is optional for the server (no `AssertReady` change); without it the fields are simply absent. - `GET /api/observers`: `neighbors_report_at` and `neighbors_count`, from one batch query in the existing cached builder. - `GET /api/observers/{id}`: also `neighbor_report`, which is `{received_at, reported_at, neighbor_count, queried_neighbors, self_scopes, self_default_scope, neighbors: [{pubkey, name, role, snr, heard_secs_ago, status, scopes}]}`. Names and roles come from the node table in one query. ## Frontend `public/observer-neighbors.js` is shared by both pages and escapes everything. - **#2270, observers list:** a sortable **Neighbors** column, e.g. `3h ago · 12`, or `—` when the observer never reported. The same value appears in the slide-over. - **#2270, observer page:** **Neighbors Report** and **Neighbors** stat cards. - **#2271, observer page:** a **Neighbors** table listing each neighbor by name (a link to the node) or key prefix, with SNR, heard, scope query status and scopes. The heading says when the list is shorter than the count, e.g. `(2 of 3 listed)`. ## Tests - **ingestor:** sanitising, the cap, live replace, the retained rules (fill only, dated by the report, undated ignored) and the MQTT topic end to end. The existing #1865 scope tests are unchanged and still pass. - **server:** the list summary, the detail with names, and both endpoints without the table. - **frontend:** - unit tests of the helpers - an XSS case for every rendered field; I checked that it fails when escaping is removed - `test-observers-headings` now expects the new column after `Last Packet` - **E2E:** `test-observer-neighbors-2270-e2e.js` intercepts the observer endpoints, since the fixture has no reports. It is listed in `scripts/non-unit-tests.json` and on shard 2. Gates that pass: - `go test -race` in `cmd/server`, `cmd/ingestor` and `internal/dbschema` - `sh test-all.sh` - `eslint@8`, with 0 errors - the XSS diff gate - these E2E suites: the new one, `test-issue-1639-observers-sort-e2e.js`, `test-observer-iata-1188-e2e.js` and `test-e2e-playwright.js` Performance: the list adds one primary-key-sized query per cache fill, and the detail adds two small queries per request. Also fixes #2330 (folded in from #2337, second commit). 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

feat(observers): radio setting per observation from the observer's radio history (#1869) (#2292)
Part of #1869. ## Problem `observers.radio` keeps only the **last** `MHz,kHz,SF,CR` an observer reported. Once an observer is retuned (say from SF7 to the EU narrow SF8 setting to listen to a neighbouring mesh), every packet it ever heard reads as heard on the new setting, and there is no way to tell an SF7 packet from an SF8 one. ## What this does As #1869 proposes, the packet data model is untouched: the setting of an observation is resolved from its observer and time. **Ingestor** (all schema in `dbschema.Apply`) - `observer_radios`: one row per stretch of time an observer, and each radio of a multi-radio node, stayed on one setting. Every live status extends the current row and a change starts a new one; retained replays never extend a row. On the first run it is seeded with every observer's current radio, which is what the UI already showed for the past. - Settings are stored canonical through `dbschema.CanonicalRadio`, so `869.4320068,62.5,7,5` and `869.432,62.50,7,5` are one setting. - `observation_radios` (`observation_id → rx_radio_id`): multi-radio openHop nodes tag each packet with `rx_radio_id` and list `radios: [{id, radio}]` in their status, so their observations resolve per radio. - The table is sparse: single-radio nodes never send the field, so `observations` and every query that scans it stay untouched. - The row id comes from the observation upsert via `RETURNING id`. - Rows are pruned with their transmissions, and a purged observer takes its history along. **Server** (read-only) - No `AssertReady` change: an absent table reads as empty and is probed again later, the same rule as `advert_route_evidence`. - The history is held in memory. The live poller checks it on every tick (two primary-key lookups), so a retune or a new `rx_radio_id` is known before the observation is broadcast. A full reload runs every 10 min. - `radio` is added to observations, packets, grouped rows (taken from the header observation) and the live feed. - `GET /api/packets?radio=MHz,kHz,SF,CR` filters by setting. - Combined with `observer=`, it means *that* observer heard it on that setting. - A radio query is served from memory instead of falling back to SQL, which would return the window unfiltered. - `GET /api/radios` (named struct) and `radio_history` on `GET /api/observers/{id}`. **Frontend** - Packet filter fields `radio`, `freq`, `bw`, `sf`, `cr`, e.g. `sf == 8` or `freq > 869.5 && bw == 62.5`. - A Radio row in the packet detail and a Radio column in its observations table (only when the server reports one). - A radio history table on the observer page once there is more than one stretch. - `RfParams.radioText` formats the setting. It escapes all five characters and returns non-numeric input as it came, escaped. ## Performance `txMatchesRadio` runs once per observation inside `filterPackets`. - Each observation costs one map lookup by observer id. - Observers with a single stretch (nearly all) answer from that lookup directly. - Retuned observers add a binary search over their few stretches. - Multi-radio observers add one lookup by observation id. - The snapshot is loaded once per filter call. `BenchmarkTxMatchesRadio`, 30K packets / 150K observations (20 observers, 2 of them retuned): ``` BenchmarkTxMatchesRadio-24 602 2056924 ns/op 0 B/op 0 allocs/op ``` Memory is one entry per stretch plus one per multi-radio observation; nothing is added per observation otherwise. ## Tests - **dbschema:** seed runs once, canonical spellings, the tables exist without `observers.radio`. - **ingestor:** - stretches extend and split; canonical spellings do not split - two radios of one node hearing one transmission over two paths each keep their own radio - a retained status does not write history - prune and purge - `rx_radio_id` reaches `PacketData` - **server:** - resolution before, between and after stretches, and with an unknown radio id - `observer` + `radio`, and grouped rows carry `radio` - incremental refresh, `/api/radios`, `radio_history`, missing tables - the benchmark above - **frontend:** the new filter fields in `tests/unit/test-packet-filter.js`, and XSS cases through the real `RfParams.radioText` and the history renderer. - **E2E:** `tests/e2e/test-radio-setting-1869-e2e.js` checks the grouped rows' radio, `sf ==` on the packets page, the detail Radio row and the observer history. It is added to `scripts/non-unit-tests.json` and to shard 2. `go test -race` in `cmd/server`, `cmd/ingestor` and `internal/dbschema` passes, along with `sh test-all.sh`, `eslint@8` (0 errors) and the XSS diff gate. The new E2E test and `test-e2e-playwright.js` pass against the fixture. ## Browser validation This runs on a live instance with six observers, one of them retuned to 869.618/62.5/SF8/CR8: - The packet detail shows `Radio: 869.432 MHz · SF7 · BW 62.5 kHz · CR 4/5`. - `sf == 7` shows 106 of 106 grouped rows and `sf == 8` shows 0 of 107; the SF8 observer has not heard anything yet. - `/api/radios` lists both settings. - No page errors. ## Notes - **The customizer (rule 8)** gets nothing: the only constants are server-side refresh intervals. - **Attribution timing:** packets heard between a retune and the observer's next status message (minutes) are attributed to the previous setting, because a stretch starts when the status is handled. This is documented at `RecordObserverRadios`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

perf(reach): answer /nodes/{pk}/reach from a rolling hop index, not a path_json LIKE scan (#2214)
Refs #2146 (reach item: "an indexed hop table would remove it"). Follows #2155. ## What changes Reach finds the observations that relayed through a node with `path_json LIKE '%"XX"%'` over every observation in the window. The cost follows the window, not the node: a quiet repeater costs about as much as a busy one. When the database does not fit in the page cache this outlives the 60 s `WriteTimeout`, the request 500s, and nothing is cached. #2146 reports this endpoint at 14.9 s average and 74.7 s max on a 10.9 GB instance. Its 1.9 s figure after #2155 is a warm-cache timing; the scan reads the whole window, so cold it is far slower (below), and it holds one of the 4 read-pool connections the whole time. This PR adds an inverted index and uses it only when it is complete for the requested window: - `observation_hops(hop, timestamp, observation_id)`, `WITHOUT ROWID`. A token lookup is a seek and the window bound is a range on the same b-tree. - Triggers on `observations` maintain it (insert, delete, `path_json` update), so prune and path-repair need no changes. - `observation_hops_coverage.since` marks how far back the index is complete. If the window starts before `since`, or the table is missing (older DB, backfill unfinished), reach runs the existing `LIKE` scan unchanged. - The ingestor owns the schema, a resumable newest-first backfill, and a daily trim to `retention.hopIndexDays` (default 14). The server stays read-only and `AssertReady` does not require the table. The backfill starts after the ingest gate opens rather than inside `OpenStore`. My first version did the latter and held live ingest in the buffer for about 15 minutes on a 13.7 GB database (nothing dropped). Chunks are 15 minutes because one-hour chunks held the writer for 2 to 7 s per commit on EBS. ## Results ### Real data: vanilla vs this branch One snapshot of a real instance (11.5 GB, 10.7M observations over 14 days) served by both builds on the same machine (8 cores, 30 GB RAM, NVMe, warm cache). One cold request per cell, seconds, repeaters from busiest to quietest by 24 h relay count. | node (relays / 24 h) | 7 d vanilla | 7 d branch | 14 d vanilla | 14 d branch | |---|---|---|---|---| | 7,314 | 24.5 | 4.5 | 8.3 | 9.6 | | 7,307 | 1.7 | 2.4 | 1.3 | 3.1 | | 7,047 | 3.3 | 2.2 | 2.0 | 2.3 | | 2,151 | 20.0 | 0.44 | 29.6 | 2.0 | | 673 | 23.7 | 0.18 | 28.5 | 0.62 | | 240 | 21.8 | 0.01 | 27.8 | 0.04 | | 52 | 21.6 | 0.00 | 28.4 | 0.00 | - Nodes with few relays drop from 20 to 30 s to under a second. - The busiest relays are about the same, sometimes slower: both builds spend their time loading tens of thousands of matching rows by primary key, which the index does not speed up. - Single runs, and page-cache state moves them a lot: an earlier run, with the file freshly cached, had vanilla's quiet nodes at 4.5 to 5 s for 7 d, close to #2155's warm figure. Read orders of magnitude, not exact figures. Nothing failed on this fast machine. **Same answers.** Unit tests check indexed rows equal `LIKE` rows, fallback on partial coverage, and trigger upkeep. On real data, 21 node/window pairs (3 to 14 days) requested from both builds at the same moment were all identical once links were compared by public key. `LIKE` ignores case and the index does not; 0 of 10.1M observations in the window have a lower-case hop. Above `reachScanRowLimit` both paths truncate, and they can keep different subsets. ### Production instance t4g.large (2 vCPU, 8 GB, EBS), 13.7 GB database, about 4.5M observations per 7 days, so the cache held a fraction of it. - Before: `days=7` on a busy node returned 500 (`context canceled`), and `days=1` took 58.5 s. - With the index (38 probes of four nodes over 18 hours): `days=7` on that node returned 200 in 23 s. The busiest probe node had a median of 0.7 s and p95 18 s. The hottest (127k relay observations in 7 d) had a median of 1.3 s, p95 52 s, and one probe past 60 s at evening peak. The quietest had a median of 0.04 s. - On 2026-10-04 the host was resized to 4 vCPU and 16 GB so the cache holds the database. Same index afterwards (493 probes): hottest node median 1.4 s, p95 1.7 s, max 38 s; quietest median 0.05 s. (From 2026-10-03 the instance also ran a local change, not in this PR, that lets reach requests continue in the background, which only affects requests over 45 s.) So on a small cold host the index turned "always fails" into "usually works" but did not make the hottest relays reliably fast. That needs cheaper row loading (a compact side table measured 4 to 10x on cold reads; kept out of this PR) or background computation. ### Benchmarks (included) ``` go test ./cmd/server -run xxx -bench ScanReachRows -benchtime 5x # 600k observations, 11 hops avg, 7 d window in 14 d, warm cache hot_token/like 816 ms rare_token/like 486 ms hot_token/indexed 293 ms rare_token/indexed 1.7 ms go test ./internal/dbschema -run xxx -bench ObservationInsert -benchtime 20000x # one observation per transaction, WriterDSN (WAL, synchronous=FULL), 11 hops without_index 23 us/op with_index 127 us/op ``` The triggers add about 100 us per observation, roughly 0.1% of a core at the production instance's 8 observations per second. They cap one writer at about 8k observations per second instead of 43k. The benchmark ran in a temp directory, so it shows CPU and b-tree cost, not disk sync cost. Over 13 days on the production instance, 0 observations were dropped and newest-observation age was p99 4 s. Four of 623 samples were 20 s or more: 91 s and 20 s came within six minutes of a container restart, 31 s came 24 hours after one (when the ingestor's daily tickers fire), and 23 s had no restart nearby. Index coverage stayed between 14.0 and 15.2 days. **Disk.** On the snapshot (`dbstat`) the index is 1.98 GB for 10.1M observations in the window, about 196 bytes each, next to 6.81 GB for `observations`. It scales with hops per observation and `hopIndexDays`. Backfill of 77M rows took 15.5 min on the production instance. **Perf justification (AGENTS.md).** Reach goes from a scan over the whole window to a seek over the matching rows. Everything new is bounded: the index by `hopIndexDays` and the daily trim, the backfill by chunk size and a cancellable context, and the server adds no in-memory state. The ingest hot path pays the trigger cost above. ## Design notes and open questions - Why not the in-memory store: it defaults to 7 days (`retentionHours: 168`) and reach offers up to 30, so it could not answer the longer windows. The other option listed in #2146, driving the query from `observations.timestamp`, is what #2155 already did. - SQLite only: the triggers use `json_each`. The optional PostgreSQL backend in #2145 would need its own equivalent. - No off switch: the table and triggers are always installed and `hopIndexDays` only sets the window. If you would rather have this opt-in, or want a smaller default for small disks, I'll change it. ## Operator notes - Upgrade: the ingestor installs the table and triggers on start and backfills. Until a window is covered, reach behaves as today. - Rollback: an older binary keeps indexing new rows with no trim. To remove it with the ingestor stopped: `DROP TRIGGER trg_observation_hops_ai; DROP TRIGGER trg_observation_hops_ad; DROP TRIGGER trg_observation_hops_au; DROP TABLE observation_hops; DROP TABLE observation_hops_coverage;` - New key `retention.hopIndexDays`, documented in `config.example.json`. ## Tests `go test ./...` passes in `cmd/server`, `cmd/ingestor` and `internal/dbschema`. New: `node_reach_hops_test.go`, `observation_hops_test.go`, `observation_hops_backfill_test.go`, and the two benchmarks. ## Update after review (commit `2291bea2`) The text above is what was reviewed at `95e17976`. Where they differ, this section is current: - **Opt-in.** `retention.hopIndexDays` unset or 0 (the default, and the value in `config.example.json`) installs nothing. A value above 0 installs the table and triggers and backfills that many days. This replaces "default 14", the "No off switch" note and the Upgrade note above. - **Changing the setting** applies at the next ingestor start: raising it backfills the gap, lowering it trims, and 0 removes the triggers and both tables. On a 10.5M-observation copy the removal took 45 to 71 s, at startup before MQTT connects. - **Case.** Hops are stored and matched upper-cased, so the index ignores ASCII case the way LIKE does. This replaces the sentence on case under "Same answers". - **Rollback.** Set it to 0 and start the ingestor once, then roll back. The manual `DROP` list above still works with the ingestor stopped. - **Disk.** A full 14-day backfill on that copy built 2.17 GB for 9.68M observations, about 224 bytes each, in 13 min 37 s. - Backfill and trim are serialized, and the chunk SQL lives in `dbschema` next to the triggers. ## Update after review, round 2 (commit `95690e8c`) Where this differs from the two sections above, this one is current: - **Startup order.** The index is installed or removed in the startup block, after the MQTT subscription is up and before the ingest gate opens, so packets arriving during a removal are buffered (`ingestBufferSize`), not lost. This replaces "at startup before MQTT connects" in the first update. - **Mark moves cover their range.** Each backfill and trim transaction indexes or deletes everything between the old mark and the new one, so a row arriving between the chunk-picking read and the transaction is accounted for either way. - **Negative `hopIndexDays`** is a config error at startup; the ingestor refuses to run. This replaces "−5 is off" in the first update. - **Server.** If the index disappears between the coverage check and the scan, the request is answered from the `LIKE` scan instead of a 500. --- 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: nullrouten <201262769+nullrouten0@users.noreply.github.com> Co-authored-by: Claude Sonnet 5.5 <noreply@anthropic.com> |

feat(#2107): backfill unresolved channel/scope rows when the key set grows (#2133)
Part 1 of #2107, scoped as discussed there: the backfill on its own, no catalogue promotion. ## Problem Ingest decides a GRP_TXT's channel and a transport packet's region scope once, at insert time. A row stored before its key was known keeps `channel_hash = 'enc_XX'` / `scope_name = ''` forever, even after the key is added — via `hashChannels` plus a restart, or at runtime when the `autoRegionKeys` tier picks up a newly declared region. On live.saarmesh.de we have been closing that gap with an out-of-tree script that rewrites the DB and restarts the container; this moves it into the ingestor and removes the restart. ## What this does **Ingestor** — `cmd/ingestor/key_backfill.go` - Runs after the write path is ready, and again whenever the key set grows (kicked after every `autoRegionKeys` refresh; a no-op when nothing is new). - Touches **only unresolved rows**: `enc_*` GRP_TXT and transport rows with `scope_name = ''`. Every `UPDATE` carries the unresolved value in its `WHERE`, so a row resolved meanwhile by live ingest keeps its value. A decrypted channel or named scope is never rewritten. - **Same decision as ingest**: `DecodePacket` with the full channel key map → `PayloadJSON`, and `regionKeySnapshot.match()` with the full snapshot — including abstaining on an ambiguous collision (#1609). The scope-match counters are not touched; they describe live traffic. - **Bounded**: each batch covers a fixed window of 5000 transmission ids. Unresolved rows are sparse (hundreds in a million), and the ingestor has a single SQLite connection, so a "next N matching rows" query would scan most of the table in one statement while ingest waits. A fixed id window keeps every read a short primary-key range scan. The writer is yielded between windows. - **Resumable and transactional**: one transaction per window holds the rewrites, their change-feed rows and the advanced cursor (`key_backfill_state`). A cancelled or crashed run resumes at its last commit; nothing is applied twice. - **Key-set growth**: a run is tied to the fingerprint of the key set it started with. If the set changes mid-run, the run restarts from the beginning, so a key added halfway still sees all of history. Each key gets one complete pass (`key_backfill_done`); a restart with an unchanged key set does no work. A key that leaves the set forgets its pass and is replayed if it returns. - **Derived field**: a named ADVERT fills `nodes.default_scope` / `inactive_nodes.default_scope` only where it is still empty. A known `default_scope` is newer evidence than a backfilled advert and is never overwritten. **Change feed** — `internal/dbschema/key_backfill.go`, `cmd/server/tx_rewrite_feed.go` - Each rewrite appends a row to `tx_rewrite_feed` in the same transaction as the rewrite. - The server tails it exactly like `advert_route_evidence`: cursor captured before `Load`, absent table re-probed (not required by `AssertReady`, so an older ingestor simply means no feed), polled from `IngestNewObservations`. It refreshes `DecodedJSON` / `ScopeName` of loaded transmissions, resets the `ParsedDecoded` cache, recharges tracked bytes, and invalidates the channel caches. **No restart needed.** - The feed carries only the transmission id; current values are read from `transmissions`, so replaying a row is harmless. Rows older than 24h are pruned. ## Tests Ingestor (`key_backfill_test.go`) — fixtures are real wire frames: GRP_TXT encrypted AES-128-ECB with the firmware MAC, transport frames with the real region HMAC. - decrypts only unresolved rows; already-decrypted and unknown-key rows untouched - backfilled `decoded_json` / `channel_hash` are byte-identical to what `BuildPacketData` stores at ingest - unique match named; a constructed two-name collision on the same payload stays unmatched; named and non-transport rows untouched - ingest scope-match counters unchanged - ADVERT fills only an empty `default_scope` - idempotent: second pass writes nothing, done keys recorded, state cleared - cancel between commits → resume from the committed cursor, every row exactly once, in order - stale run fingerprint (key added mid-run) → restart reaches rows below the old cursor - a later key only adds its own rows; a removed key is replayed over the gap when it returns - a row resolved between decide and commit keeps its value and gets no feed entry - channel hash byte derivation matches the builtin Public key (0x11) - old feed rows pruned Server (`tx_rewrite_feed_test.go`) - rewrite reaches the loaded store through the normal `IngestNewObservations` poll, including a previously parsed `ParsedDecoded` (verified to fail without the `sync.Once` reset) - cursor starts at the load watermark - absent feed is a no-op and is picked up once created, without restart - failed read keeps the cursor and retries - feed row for an unloaded transmission advances the cursor and is ignored `gofmt` clean, `go vet` clean, no `go.mod` / `go.sum` changes. ## Validation against production data Ran the backfill on a snapshot of live.saarmesh.de taken **before** last night's run of our out-of-tree script (13,100 unresolved rows, 164 channel keys, 24 region keys incl. 2 derived), with the current config. It rewrote **the same 31 transmissions with the same channel names** as the script did on production (compared by id), named 0 scopes (script: 0), and a second pass wrote nothing. Browser validation (AGENTS rule 2): this changes no UI. The visible effect — a decrypted message or named scope appearing without a restart — is covered by the server feed tests; I have not yet run it against a deployed instance. ## Notes for review - Window size (5000 ids), inter-batch yield (10 ms) and feed retention (24h) are constants for now; per rule 8 they can move to config/customizer later if anyone needs to tune them. - `client_rx_observations.scope_name` is not backfilled here; happy to add it in a follow-up if wanted. - The orphaned "scope-repair" mention in `region_keys.go`'s `scopeMatch.Candidates` comment predates this PR; I left it alone. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01BKaogNXgy8dEQruqzR5foP --------- Co-authored-by: SaarMesh-Bot <300107934+SaarMesh-Bot@users.noreply.github.com> Co-authored-by: Claude <noreply@anthropic.com> |

feat(analytics): split adverts using recorded route evidence (#2088)
Red commits: `dc7dcbe`, `76e3217` ([assertion failures](https://github.com/Kpa-clawbot/CoreScope/actions/runs/37059977385)). Fixes #2041; supplies #2085's backend contract. Records at most two route bits per retained advert. Node flood counts now use the same evidence, including mixed and transport-flood adverts. Analytics failures log/count errors while core observation, path and liveness writes continue. The unrelated recent-advert limit clamp is removed. Direct adverts (empty path) describes the observed remaining path across valid hash widths. Firmware can forward an advert down to an empty path; this cannot establish original send mode or RF distance. The `zero_hop` API spelling remains compatible. Successful post-upgrade evidence writes survive observation replacement and restart. Older overwritten frames and failed writes can leave gaps. The UI explains automatic background backfill. ## Measured validation Synthetic Windows workloads; timings are not production guarantees: - 300K retained adverts, one-hour window: median 64.35→39.84 ms; 13.98 MB→145 KB allocated. Seven-day allocations unchanged; five paired samples. - 1M transmissions/11M observations: backfill 5m43s. Simple 10 Hz writer: all 3,423 observations persisted; p99 28 ms, maximum 323 ms. - Simulated pre-backfill cursor: retained evidence ready 4m21s; full catch-up 6m41s, 122 cache invalidations. Normal completed-migration startup bulk-loads current evidence. Portable opt-in scale tests and window benchmarks are included. All 183 frontend suites, full server tests, targeted races, lint and real-API desktop/mobile checks passed. Full [Linux CI](https://github.com/Kpa-clawbot/CoreScope/actions/runs/37063210229) passed at `36def9c`; three independent reviews are clear. Local Windows testing hit the unchanged symlink-privilege test. No configuration changes. Preflight overrides: external script/OpenClaw profile unavailable; repository checks and Chromium used. |

perf(sqlite): swap modernc.org/sqlite for mattn/go-sqlite3, cross-built with zig (#1992)
Swaps the SQLite driver from `modernc.org/sqlite` (pure Go, SQLite
3.46.0) to `github.com/mattn/go-sqlite3` (cgo, bundled SQLite 3.53.4),
and pays the resulting cross-compilation cost with `zig cc`.
Draft because the riskiest part of this deletes rows — see [Please
review this part first](#please-review-this-part-first) — and because
three things remain unverified at the bottom.
`modernc.org/sqlite` is a transpilation of the C amalgamation. This repo
is read-heavy: `cmd/server` chunk-loads a graph at startup and fans out
neighbour/topology/analytics queries per request, and it pays for that
transpilation on exactly those paths. Head-to-head on the same
120k-transmission / 240k-observation database, running our own hot-path
SQL under both drivers (Apple M4, `-count=5`, medians):
| workload | modernc | mattn | |
|---|---:|---:|---|
| chunk load (`chunked_load.go` v3 join, 20k tx) | 449ms | 196ms |
**2.3×** |
| aggregate scan (240k-row join + `GROUP BY`) | 276ms | 137ms | **2.0×**
|
| 1500 prepared-statement lookups | 512ms | 403ms | **1.3×** |
Allocations fall with it: 1.12M vs 1.64M allocs and 21MB vs 30MB on the
chunk load.
**Superseded by a production run.** @efiten measured both drivers on a
real instance — 11,077,038 observations, 9.7GB database, 4-core arm64 —
as server-only containers against the same live volume, one at a time,
with round 2 reversing the order so the page cache favours the old
driver:
| | audit 7d | audit 24h | background fill (13 chunks) | start →
/api/health |
|---|---:|---:|---:|---:|
| modernc, round 1 | 16.67s | 2.27s | 130.2s | 16.6s |
| mattn, round 1 | 7.87s | 1.34s | 93.8s | 13.5s |
| mattn, round 2 | 8.15s | 1.35s | 96.4s | 13.0s |
| modernc, round 2 | 13.46s | 2.29s | 137.8s | 15.5s |
Warm, the old driver improves to 13.46s on the 7d audit and still loses
by ~1.8×. Chunk load is ~1.4×. `/api/nodes?limit=500` is 0.039s against
0.037s — nothing.
**So the real gain is ~1.4–1.8× on the paths that matter, not 2–2.3×.**
The shape the harness predicted holds — scans and joins gain, small
lookups do not — which is more reassuring than the magnitude would have
been. Quote these numbers.
**The counterweight**, cold and native on that machine: a build goes
from **52s to 163s**. An instance that builds its own image pays that
per deploy.
## The build is cgo now, and one thing about that is a trap
**`CGO_ENABLED=0` still builds.** mattn links a stub, and the binary
dies on its first query with `go-sqlite3 requires cgo to work. This is a
stub`. A green build is not evidence of anything here, which is why
`AGENTS.md` now says so explicitly. `GOOS=linux go build` genuinely
cannot cross-compile any more.
A new root `Makefile` is the entry point. `make crossbuild` uses `zig cc
-target {x86_64,aarch64}-linux-musl` and links static, so each artifact
stays a single self-contained file and the `alpine:3.20` runtime no
longer depends on the base image's libc at all.
`-Wl,-s` is load-bearing: Go's own `-s -w` does not reach the musl
objects zig links in, and without it the server binary is 19.8MB instead
of 12.1MB.
The Dockerfile keeps its single `$BUILDPLATFORM` builder — still no QEMU
for compilation — and gains a checksum-pinned zig plus BuildKit cache
mounts. The mounts are not a nicety: without them an image build
recompiles the amalgamation from cold and takes over half an hour.
## Please review this part first
`internal/dbschema/dedup_index.go` **deletes observation rows**. It is
the one part of this change that can lose data, and it exists because
the migration exposed a real bug rather than causing one.
`stmtInsertObservation` resolves its `ON CONFLICT` against
`idx_observations_dedup`, which `cmd/ingestor/db.go` only ever created
inside the branch that creates the `observations` table for the first
time. Any database whose table predates that branch never got one, so
the UPSERT had no conflict target. modernc failed on the first insert;
mattn fails at `OpenStore`. Same bug, found earlier.
Creating the index unconditionally repairs it — but the index is what
was supposed to prevent duplicates, so a database that never had it can
already hold rows violating it. **`test-fixtures/e2e-fixture.db` in this
repo holds one.** So duplicates are collapsed first. Refusing is not the
safer option: without the index the ingestor cannot prepare its UPSERT,
so it cannot start at all.
Replaying that UPSERT faithfully is subtler than it looks, and a first
cut of this got it wrong twice:
- `COALESCE(excluded.x, x)` means the **incoming** value wins, so down a
group in id order the survivor keeps the **last** non-NULL value. Taking
the first silently discarded newer readings.
- The UPSERT names exactly five columns (`snr`, `rssi`, `score`,
`raw_hex`, `resolved_path`). Every other column must keep the surviving
row's own value; merging those too invents history the ingestor would
never have written.
Merge, delete and `CREATE UNIQUE INDEX` now share one transaction. Split
apart, a writer inserting a duplicate in the gap fails the index
creation while leaving the deletions committed — rows destroyed and no
index to show for it.
Cost, measured on 2.4M synthetic rows holding 5 duplicates: **4.1s**,
holding the write lock throughout, once, at ingestor startup before MQTT
subscribe. Materialising the duplicate-group scan once rather than per
column took that from 9.7s; the pathological case (400k of 600k rows
duplicated) is 5.7s, slightly worse than the 4.2s it was before that
change.
## Four more behavioural differences
Full detail in `docs/sqlite-driver-migration.md`. Briefly:
**Statement preparation is eager.** modernc's `newStmt` stored the SQL
and compiled lazily; mattn calls `sqlite3_prepare_v2` inside `Prepare`,
so SQL naming a missing table fails at *open*. 59 server tests failed on
this alone, all fixtures with partial schemas. `OpenDB` keeps failing
loudly (#1901; `main.go` gates on `dbschema.AssertReady` anyway) and the
fixtures now declare what they are prepared against via
`ensurePreparable`. This also exposed nine `nodes(pubkey …)`
declarations across seven files, where production has only ever had
`public_key` — lazy compilation had hidden the mismatch for as long as
it existed.
**`synchronous` silently dropped FULL → NORMAL.** mattn defaults it to
NORMAL and executes the pragma unconditionally, where SQLite's own
default (what modernc left alone) is FULL. In WAL mode that weakens
durability under power loss. Pinned in `dbschema.WriterDSN`, which both
writers now share — `cmd/migrate` kept a bare path at first and so
quietly wrote at NORMAL, which is what a second copy of a DSN buys you.
**The DSN dialects are mutually invisible.** modernc understood only
`_pragma=name(value)`, mattn only `_`-prefixed parameters, and neither
errors on the other's form — a driver-only rename would have dropped
every pragma in silence. `_journal_mode=WAL` is also gone from the
server's read handle: modernc ignored it, mattn honours it, and setting
`journal_mode` on a read-only connection is a write. Dropping
`_busy_timeout` with it costs nothing, since mattn already defaults to
5000ms — which means the read handle finally *gets* the busy timeout it
had silently lacked.
**`mode=ro` survives for a non-obvious reason.** mattn always passes
`READWRITE|CREATE` and its amalgamation has `SQLITE_USE_URI=0`; what
makes the URI work is its C wrapper ORing `SQLITE_OPEN_URI` in. So the
#1283/#1289 invariant holds with no build flags — but it depends on the
`file:` prefix. `cmd/decrypt` had been building its DSN without one, so
its `mode=ro` had never applied and a missing path was created
read-write. Fixed in passing; never a migration regression.
## What did not change
No modernc-specific API was in use: no `RegisterFunction`, no
`*sqlite.Conn`, no `sqlite/lib` error constants, no `sql.Register`. No
`time.Time` is ever bound as a query argument, so driver time handling
is not in play. Both drivers convert declared
`DATE`/`DATETIME`/`TIMESTAMP` columns to `time.Time`, so
`/api/dropped-packets` keeps emitting `dropped_at` as RFC3339 — an
earlier draft "fixed" that with a `CAST` and would have been the
regression.
## Tests and CI
New regression tests, each written because something got through without
it:
- `TestEnsureObservationsDedupIndexKeepsLatestValues` — the merge
ordering. The original test used complementary NULLs, which passes
whichever direction you pick, which is why the bug survived it.
- `TestCollapseDuplicatesAndIndexIsAtomic` — a failed index creation
must roll the deletions back.
- `TestOpenStorePragmas` / `TestWriterDSNPragmas` — every writer pragma,
read back through the store's own connection. A separate `sqlite3`
session or the startup log line would prove nothing.
- `TestOpenDBRefusesMissingDatabase` — the read-only invariant, which
now rests on a detail of the driver's C wrapper.
- `TestEnsurePreparableMatchesPrepareStatements` — fails when a new
prepared statement outgrows the fixture helper.
CI gains test execution for `cmd/migrate` and `internal/dbschema`, which
had none and both open the database. A PR-time two-arch build plus an
arm64 QEMU smoke gate is new: the GHCR push is push/tag-only, so without
it nothing on a PR would exercise zig, static musl linking or arm64, and
the first signal would arrive on master. `cache-dependency-path` widens
from 2 of the 5 tracked `go.sum` files to all of them.
`make test` passes across all 14 modules, `cmd/server` also under `-race
-count=2` with no failures and no races. `gofmt` and `go vet` clean.
Release-routing and Dockerfile COPY-invariant gates pass.
## Verified by running
- All 8 cross-builds static and correct-architecture; both arches of the
container image built, exported and run under QEMU, serving
`/api/health` and `/api/nodes` against a 2.9M-observation production
snapshot.
- The `migrate` binary repairing that snapshot's duplicate on bare
Alpine.
- `CGO_ENABLED=0` producing a binary that builds and then fails on first
query.
## Not verified
- ~~The 2–2.3× figures come from a standalone harness, not this load
under the old driver.~~ **Closed** by @efiten's production run above,
which also corrected the multiplier.
- SQLite 3.46.0 → 3.53.4 query-planner differences on queries with no
total `ORDER BY`.
- Sustained live ingest through the new writer DSN, and the duplicate
collapse against a database an ingestor is actively writing to. Verified
against a static snapshot only, and the collapse is measured at 4.1s on
2.4M synthetic rows with 5 duplicates — well short of an 11M-row
instance. @efiten has offered a staging instance taking real MQTT
traffic; **this is the item to close before the PR leaves draft.**
An earlier revision of this branch shipped the dedup merge in the wrong
direction with a green test suite, and review then found three more
things in the same file: the repair gated on an error string, a
non-atomic TEMP table drop aimed at the wrong connection, and a deletion
whose only record was a row count. All fixed in

feat(#1865): ingest observer /neighbors as confirmed scope evidence (#1971)
Carries SaarMesh-Bot's implementation from the closed #1867 forward onto current master, 67 commits later, and surfaces the result on the per-node Reach report. The declared region list a repeater answers with is now stored on the node as configured_scope, normalised to the same leading-# syntax default_scope already uses so the two are directly comparable. That normalisation is the point @cwichura raised on #1865 and @dborup agreed with before the original PR closed. Co-authored-by: SaarMesh-Bot <300107934+SaarMesh-Bot@users.noreply.github.com> |

perf: index, cache, and deflake /api/channels queries (rebase of #1887) (#1936)
Continues #1887 by @Jonher937. The commit is theirs, authorship unchanged; I only rebased it onto master. It went CONFLICTING because #1934 (prepared statements, originally @Joel-Claw's #1878) landed in the same `DB` struct. Both PRs add fields there and this one also replaces the single-slot channels cache. Resolution: kept this PR's keyed caches (`channelsCache`, `encChannelsCache`, `msgCache` plus their entry types and TTL constants) and kept master's thirteen prepared-statement fields alongside them. The old single-slot `channelsCacheKey`/`channelsCacheRes`/`channelsCacheExp` trio is gone, which is the point of this PR. Nothing else touched. Verified: `cmd/server` builds and the **full suite passes**, not just the channel tests. My review stands: approve, with two questions that do not block and are worth a look at some point. 1. `msgCache` is keyed by `hash|limit|offset|region`, and `offset` grows without bound as someone pages through a channel. Each entry also holds a full page of message maps, so a full 256-entry cache at `limit=50` holds around 12,800 maps. The other two caches are keyed by region only and genuinely low-cardinality as your comment says; this one is the odd one out. 2. `getMsgCache` returns the cached slice directly, so every hit hands the caller the same message maps. If any handler mutates one before serialising, it corrupts the cache for the next ten seconds. Same class as the finding on #1871, which was fixed there by copying at the two broadcast sites.

perf(#1740): replace idx_tx_last_seen with partial index WHERE last_seen=0 (#1756)
Fixes #1740. ## What Replace the full `idx_tx_last_seen` with a partial index `WHERE last_seen=0`. Two ordered, sequential migrations in `internal/dbschema/dbschema.go::ensureTransmissionsLastSeenColumn`: - **(a)** `CREATE INDEX IF NOT EXISTS idx_tx_last_seen_zero ON transmissions(id) WHERE last_seen=0` - **(b)** `DROP INDEX IF EXISTS idx_tx_last_seen` — gated after (a) succeeds (sequential `Exec`; (b) never runs if (a) errors) ## Why The only consumer is `chunkedTxLastSeenBackfill`'s `WHERE last_seen=0` scan + `MAX(id)` lookup. The full index covers ALL rows including the long tail where `last_seen != 0` after backfill converges (71K+ rows in prod per carmack's #1740 note). The partial index degenerates to ~the count of un-backfilled rows (0 in steady state, bounded by ingest rate during ops) and stops competing for page cache. ## Migration cost Both migrations are sync and annotated `PREFLIGHT: async=false`: - (a) `CREATE INDEX` on partial subset `WHERE last_seen=0` is bounded by un-backfilled rows — a small superset of the inflight ingest window, not a full table scan. - (b) `DROP INDEX` is a metadata-only schema rewrite in SQLite — no row scan at any size. `dbschema/` has no access to `Store.RunAsyncMigration` (that helper lives in `cmd/ingestor/` and is the wrong layer for the schema source-of-truth per #1321), so sync is the only path here regardless. ## TDD - **RED** `a529f0f4`: `EXPLAIN QUERY PLAN` test asserting the backfill `MAX(id) WHERE last_seen=0` query uses `idx_tx_last_seen_zero` + a second test asserting the legacy `idx_tx_last_seen` is dropped post-Apply. Both failed on assertion (planner picked the full index; partial index didn't exist). - **GREEN** `208fde8a`: add migrations (a) and (b). Both tests pass. ## Files touched - `internal/dbschema/dbschema.go` — swap the index - `internal/dbschema/dbschema_test.go` — `EXPLAIN QUERY PLAN` pin + DROP assertion - `cmd/ingestor/db.go` — comment refresh only (idx_tx_last_seen → idx_tx_last_seen_zero) ## Acceptance - ✅ New partial index created - ✅ Old full index dropped via gated migration (sequential, order preserved) - ✅ Query plan test asserts partial-index usage - ✅ Existing migration tests still green (`internal/dbschema`, `cmd/ingestor` TestIssue1690 + applySchema) --------- Co-authored-by: clawbot <bot@openclaw> |

fix(#1690): cold-load uses last_seen (effective recency) instead of first_seen (#1691)
## #1690 — cold-load uses wrong time axis (RED → GREEN) The on-disk DB has thousands of long-lived hashes with recent traffic. Prod's cold-load filter (`transmissions.first_seen >= cutoff`) is bound to a column that is set once at insert time and never updated — so re-observation of an old hash does not move it into the hot window. Result: prod cold-loaded ~0.3% of the on-disk rows and flipped `backgroundLoadComplete=true` without ever walking the retention window (the `retentionHours - hotStartupHours <= 0` short-circuit at line 1353 of `cmd/server/store.go`). ### Three sub-fixes **A) Denormalize `transmissions.last_seen`** so cold-load can window on effective recency. - `internal/dbschema/dbschema.go::ensureTransmissionsLastSeenColumn` adds the column + `idx_tx_last_seen` (single-column INTEGER ALTER + index; both PREFLIGHT-annotated as cheap metadata-only ops). - `cmd/ingestor/db.go::OpenStoreWithInterval` schedules `tx_last_seen_backfill_v1` via `Store.RunAsyncMigration` — `UPDATE transmissions SET last_seen = MAX(observations.timestamp) WHERE last_seen = 0` — non-blocking on boot (1.9M+ obs row scan in prod). - Writer-side: `InsertTransmission` seeds `last_seen` on initial insert, and every observation insert bumps `last_seen = ?` via prepared statement `stmtBumpTxLastSeen` (conditional `last_seen < ?` so out-of-order ingest never goes backwards). - Reader-side: `cmd/server/store.go::Load`, `loadChunk`, and `cmd/server/chunked_load.go::LoadChunked` switch the WHERE/ORDER-BY clauses to `t.last_seen` when the column is present (PRAGMA-detected via `DB.hasLastSeen`). Test/legacy DBs without the column fall back to `first_seen` so existing fixtures stay green. **B) Honest `backgroundLoadComplete` gating.** - Drop the `retentionHours - hotStartupHours <= 0` short-circuit. Prod runs with both at 12h, which flipped Done=true immediately. - After the chunk loop, query `SELECT COUNT(*) FROM transmissions WHERE last_seen >= retentionFloor` and compute `loadCoverageRatio = inMem / inDB`. Done=true only when `ratio >= 0.90` AND no chunk errors. `backgroundLoadFailed=true` + `backgroundLoadError` populated otherwise (e.g. `"loaded 20.0% of 5000 rows (1000 in memory)"`). - `bgErrMu`-guarded `loadCoverageRatio` + `backgroundLoadErr` so the perf endpoint can read them without blocking the writer. **C) Perf exposure.** `PerfPacketStoreStats` gains `RetentionHours`, `OldestLoaded`, `LoadCoverageRatio`, `BackgroundLoadError` — surfaces what fraction of the on-disk DB the in-memory store currently reflects, so operators can see the 0.3% case in `/api/perf` without reading the logs. ### TDD trail - **RED**: `05f0c6dd2bea6dc37324c548a49564d739aca920` — failing tests + 21-line store.go scaffolding. CI on this commit failed on assertions (intended). - **GREEN**: this PR's HEAD commit (8 files, +271/-24). Targeted suite: `Test1690_ColdLoad_TimeAxis`, `Test1690_BackgroundLoadHonesty`, `Test1690_PerfStats_NewFields`, `TestHotStartup_*`, `TestIssue1690_LastSeenUpdatedOnObservation` — all pass. Anti-tautology: locally reverted the `if !s.backgroundLoadFailed.Load()` guard around `backgroundLoadDone.Store(true)` — `Test1690_BackgroundLoadHonesty` fails on the assertion `"backgroundLoadDone=true with only 1000/5000 packets loaded; must be false until coverage ≥ 90%"`. Restored. ### Async-migration preflight - `ensureTransmissionsLastSeenColumn` — ALTER + CREATE INDEX both `// PREFLIGHT: async=true reason="..."` annotated. - `tx_last_seen_backfill_v1` — wrapped in `Store.RunAsyncMigration`. - `stmtBumpTxLastSeen` prepared statement — annotated; it is a row-level UPDATE BY PRIMARY KEY, not a migration. ### Preflight overrides PREFLIGHT-MIGRATION-SCALE: <30s N=5K - check-async-migration: justified for `cmd/server/issue1690_cold_load_test.go` CREATE TABLE/INDEX statements — these build an in-memory test fixture DB (≤5000 rows, runs in <1s in CI), not a prod migration.

feat(#1290): use firmware repeat:on|off hint to exclude listener-only observers from disambiguator (#1624)
Closes #1290. cross-stack: justified — backend persists firmware-side `repeat` hint to a new observers column, frontend surfaces the listener/repeater status as a badge on the observers list and node-detail Heard By table per the issue's UI acceptance criterion. ## What Firmware 1.16 publishes a `repeat: on|off` flag in the MQTT `/status` JSON (confirmed by @cwichura on the issue thread — see [`MQTTMessageBuilder.cpp:58`](https://github.com/agessaman/MeshCore/blob/b45373a31f111fb0de98bb3b168226d09ceadc47/src/helpers/MQTTMessageBuilder.cpp#L58) in `agessaman/MeshCore mqtt-bridge-implementation-flex`). Listener-only observers (`repeat:off`) by firmware contract never relay packets, so they cannot legitimately be a hop in someone else's resolved path. This PR plumbs the hint end-to-end so the disambiguator stops considering them. ## How * **`internal/dbschema`**: idempotent `can_relay INTEGER DEFAULT 1` migration on `observers`, plus `AssertReady` probe (server fatal-logs if absent). Mirrored in `cmd/ingestor/db.go` `CREATE TABLE` for fresh DBs. Annotated `PREFLIGHT: async=true` — `DEFAULT 1` is constant so SQLite does this as a metadata-only schema rewrite. * **`cmd/ingestor`**: `extractObserverMeta` accepts `repeat` as bool, case-insensitive string (`on|off|true|false|yes|no`), or numeric `0|1`. Missing field → `nil` → `COALESCE` preserves the existing column value (back-compat with legacy observers). Plumbed through `UpsertObserverAt` and the prepared upsert statement. * **`cmd/server`**: `GetNonRelayObserverPubkeys` + new `prefixMap.markNonRelay` drop matching candidates inside `pm.resolveWithContext` at the top of the resolver, so all 4 tiers see the pruned candidate set. `ObserverResp.CanRelay` is surfaced on `/api/observers` and `/api/observers/{id}`. `GetNodeHealth` enriches per-observer rows with `can_relay` so the node-detail badge renders. Probe-and-fall-back when the `can_relay` column is absent (legacy test fixtures). * **`public/`**: listener vs repeater pill on observers list, observer detail `Relay` stat card, and node-detail `Heard By` table. CSS uses existing theme vars. ## Test Added `TestResolveWithContext_ExcludesNonRelayObservers_Issue1290` in `cmd/server/resolve_non_relay_1290_test.go` covering all three required cases: * `repeat:off` pubkey → not a candidate (assertion failed in red commit `5f7fdb96`, passes after green `f12911dc`) * `repeat:on` pubkey → still a candidate (regression guard) * legacy obs (no field) → still a candidate (back-compat) Red→green proof: ``` $ git log --oneline origin/master..HEAD |

feat(observers): surface naive-clock observers as ⚠️ chip + detail banner (#1478) (#1480)
## Summary Issue #1478 — surface observers whose envelope timestamps are being clamped because they're emitting zone-less local-time strings (UTC-N observers showed up perpetually as "Stale" before #1466, and per-packet rxTime is still clamped to ingest time for them, muddying propagation-delay analytics). Now the UI tells operators which observers are misconfigured + how to fix it. ## What changed ### Ingestor (cmd/ingestor) - New `observers_clock_naive_v1` migration adds three columns to `observers`: - `clock_skew_seconds INTEGER` (signed: negative = behind UTC, positive = ahead) - `clock_skew_count_24h INTEGER` (rolling 24h event count) - `clock_last_naive_at TEXT` (RFC3339 timestamp of last clamp) - `resolveRxTime` now returns `(rxTime, naiveSkewSec)`. The packet-handler call site invokes `store.RecordNaiveSkew(observerID, deltaSec)` whenever a naive envelope is clamped (the existing >15 min naive-tolerance path). The counter resets to 1 if no event in the prior 24h, else increments. Single INSERT-or-UPDATE round trip per clamp. ### Server (cmd/server) - `Observer` struct + `GetObservers` / `GetObserverByID` extended to scan the three new columns. - `ObserverResp` gains four JSON fields exposed by `/api/observers` and `/api/observers/{id}`: - `clock_naive` (bool, derived from `clock_last_naive_at` being within 24h) - `clock_skew_seconds`, `clock_skew_count_24h`, `clock_last_naive_at` - Decay is **read-side**: a stale event yields `clock_naive=false` with zero counts. No background sweep, no writes from the read-only server, no race with the ingestor. ### Frontend (public) - `window.ObserversNaiveChip.render(o)` — total render helper, returns ⚠️ chip HTML when `o.clock_naive===true`, `""` otherwise. Used inline in the observers-list `name` cell and in the row-detail slide-over. Tooltip explains magnitude + direction + count + fix. - `window.ObserverDetailNaiveBanner.render(obs)` — yellow alert banner at the top of the observer-detail page with the skew magnitude, last-event timestamp, and the actionable fix ("Set host clock to UTC, OR emit Z-suffixed/offset-aware timestamps from the observer script"). ## TDD trail - `5ddd5b42` red: backend `cmd/server/observer_naive_clock_1478_test.go` (3 tests asserting JSON fields + 24h decay) + frontend `test-observer-naive-clock-1478.js` (8 jsdom-style tests asserting helpers exist and render correctly). Both failed on master with field-missing / export-missing assertions. - `4ecc79c8` green backend: schema + Observer / GetObservers / ObserverResp / handler decay. - `2137ab81` green frontend: chip + banner helpers and call sites. ## Tests - `cd cmd/server && go test ./...` → all green (full suite, 46s) - `cd cmd/ingestor && go test ./...` → all green (full suite, 98s) - `node test-observer-naive-clock-1478.js` → 8/8 pass - `node test-frontend-helpers.js` → unchanged from master (pre-existing failures only) ## Acceptance (issue #1478) - ✅ Observer running with `python datetime.now().isoformat()` (naive, off by N hours) → `clock_naive=true` after the next clamp → UI shows ⚠️ chip + banner. - ✅ Observer with `datetime.now(timezone.utc).isoformat()` (Z-suffixed) → never clamped → never flagged. - ✅ Observer that fixed its clock → `clock_naive` returns to `false` 24h after the last clamp event (read-side decay).

feat(server): persist multi-byte capability across restart + O(1) per-key lookup (#903) (#1324)
## Summary Follows the reconciliation recommendation in #916 — extracts only the NET-NEW persistence layer from that PR (which is now superseded by #1002 for the overlay UI) into a focused 6-file change against current master. **What this adds:** - `multibyte_sup_v1` migration: `multibyte_sup INTEGER NOT NULL DEFAULT 0` + `multibyte_evidence TEXT` on `nodes`/`inactive_nodes` so capability survives restart - `hasMultibyteSupCols` schema detection gates the persist/load paths - `loadMultibyteCapFromDB()`: pre-populates `mbCapSnapshot`/`mbCapIndex` at startup — cold starts serve last-known capability without waiting for the first ~15s analytics cycle - `maybePersistMultibyteCapability()` + `persistMultibyteCapability()`: after each analytics cycle; TryLock-gated (concurrent cycles coalesce); skips `sup==0` entries (data-destruction guard) - `GetMultibyteCapFor(pk)`: O(1) map lookup; both `handleNodes` and node-detail call sites updated from the O(N)-alloc `GetMultiByteCapMap()` **What this explicitly does NOT change:** - API field names (`multi_byte_status`, `multi_byte_evidence`, `multi_byte_max_hash_size`) - `EnrichNodeWithMultiByte` — unchanged - `GetMultiByteCapMap` — still present for any external callers - `public/map.js`, `public/live.css`, `Dockerfile`, `docs/` — zero frontend churn ## Test plan - [x] `TestMultibyteCapPersistRoundTrip` — confirmed values survive persist → fresh-store load - [x] `TestMultibyteCapPersistSkipsUnknown` — data-destruction guard: `sup==0` entry does not overwrite DB-confirmed value - [x] `TestMultibyteCapMaybePersistCoalesces` — TryLock coalesces 10 concurrent callers without deadlock - [x] `TestMultibyteCapGetMultibyteCapForO1` — O(1) index returns correct entry / false for unknown pubkey - [x] `TestMultibyteCapLoadFromDB` — only `sup>0` rows loaded; `sup==0` row excluded - [x] `TestSchemaMultibyteSupColumns` — migration adds columns to both tables; idempotent on second `OpenStore` - [x] All existing `TestMultiByteCapability_*` tests pass unchanged - [x] Full ingestor test suite: `ok` in 27s - [x] `go build ./cmd/server/ && go build ./cmd/ingestor/` clean 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com> Co-authored-by: openclaw-bot <bot@openclaw> |

fix(dbschema): canonical source for optional column migrations — fixes startup race (closes #1321) (#1322)
Red commit `2a8102b9` (failing test) → green commit `bb957c9f`. CI: https://github.com/Kpa-clawbot/CoreScope/actions/workflows/ci.yml?query=branch%3Afix%2Fissue-1321 Fixes #1321. ## Why On staging `/api/scope-stats` 500'd with `scope_name column not present` despite the ingestor adding the column ~0.5s after server startup. `cmd/server/db.go detectSchema()` runs in `OpenDB` and caches `hasScopeName`/`hasDefaultScope`/`hasObsRawHex` booleans. With supervisord launching server + ingestor simultaneously, the server's PRAGMA can fire BEFORE the ingestor's `ALTER TABLE` completes — and the boolean stays false until the server restarts. Same race class as #1283; #1289 moved server-side ensures to `dbschema` but the optional columns the ingestor still owned were left out. ## Fix — option (c) from the issue Made `internal/dbschema/dbschema.go` the single source of truth for the optional columns the server detects. **Migrations moved from `cmd/ingestor/db.go applySchema` into `dbschema.Apply`:** - `transmissions.scope_name` + `idx_tx_scope_name` partial index - `nodes.default_scope` - `inactive_nodes.default_scope` - `observations.raw_hex` **`AssertReady` now asserts** every one of those columns. The server cannot start with stale-false booleans because `AssertReady` will fatal first if the columns are missing. The ingestor's old gated blocks are replaced with pointer comments so anyone hunting for them lands in `dbschema.go`. The `_migrations` marker rows are preserved (`INSERT OR IGNORE`) to keep legacy DBs idempotent. **Documented invariant** in the package doc: any new optional column the server PRAGMA-detects belongs in `internal/dbschema/dbschema.go`, NOT in `cmd/ingestor/db.go applySchema`. ## Tests Added `internal/dbschema/dbschema_test.go` (RED in `2a8102b9`): - `TestApplyAddsOptionalColumns_CanonicalSource` — post-`Apply`, all four columns must exist. - `TestAssertReady_RequiresOptionalColumns` — `AssertReady` must refuse a DB missing them AND pass after full `Apply`. `cmd/ingestor` and `cmd/server` full suites green. --------- Co-authored-by: openclaw-bot <bot@openclaw.local> |

refactor(db): finish #1283 — Option 4: ingestor owns neighbor-graph + schema migrations; server is read-only (fixes #1287) (#1289)
Red commit: https://github.com/Kpa-clawbot/CoreScope/commit/eae179b99b5fd34924547632aa8f8025c405aa53 (CI: pending — opens with this PR) Finishes #1283. RED test `TestServerSourceHasNoCachedRWCalls` goes from failing (13 writer call-sites) to GREEN (zero). Per #1287 Option 4 (https://github.com/Kpa-clawbot/CoreScope/issues/1287#issuecomment-4485099992): ingestor owns the neighbor graph build + persist; server reads the snapshot. **Category A — Schema migrations** → new `internal/dbschema` package. `dbschema.Apply(rw)` runs in `cmd/ingestor` startup (in `OpenStore`). `dbschema.AssertReady(ro)` runs in `cmd/server/main.go` and FATAL-LOG-EXITS if any expected column/index/table is missing — the operator must restart the ingestor first. Covers indexes, `neighbor_edges`, `observations.resolved_path`, `observers.{inactive,last_packet_at,iata}`, `(inactive_)nodes.foreign_advert`, `transmissions.from_pubkey`. **Category B — Backfill** → ingestor. `BackfillFromPubkey` and observer-blacklist soft-delete moved to `cmd/ingestor/maintenance.go`. Server keeps an inert `fromPubkeyBackfillSnapshot` stub for `/api/healthz` API compatibility. **Category C — Neighbor-graph persistence (Option 4)** → ingestor writes, server reads. - Ingestor (`cmd/ingestor/neighbor_builder.go`): every 60s scans `observations + transmissions`, extracts edges (originator↔first-hop for ADVERTs; observer↔last-hop for all), resolves hop prefixes via a node-table prefix index, upserts into `neighbor_edges`. - Server (`cmd/server/neighbor_recomputer.go`): every 60s re-reads `neighbor_edges` and atomic-swaps the resulting `NeighborGraph` into `s.graph`. Initial load is synchronous on startup. All server-side incremental edge writers (the two `asyncPersistResolvedPathsAndEdges` paths in `cmd/server/store.go`) are gone. - Neighbor-edge daily prune (`PruneNeighborEdges`) moved to ingestor. **Why Option 4**: clean read/write separation, no startup CPU spike (server loads existing snapshot instead of rebuilding from history), no IPC/delta-protocol churn. Staleness budget ~60s — same model as the analytics recomputers in #1240 / #1248 / #672 axis 2. **Recomputer interval default for neighbor graph**: 60s (`NeighborGraphRecomputerDefaultInterval`, `NeighborEdgesBuilderInterval`). **Invariants added**: - `TestServerSourceHasNoCachedRWCalls` (RED commit eae179b9): grep enforces zero `cachedRW(`, `mode=rw`, or `sql.Open(_journal_mode=WAL…)` in non-test `cmd/server/` sources. - `TestServerStartupRequiresMigratedSchema`: server refuses to start against an unmigrated DB. - `TestNeighborGraphRecomputerLoadsSnapshot`: post-write snapshot is picked up on the next refresh. - `TestNeighborEdgesBuilderUpsertsFromObservations`: end-to-end pipeline writes the expected edge. `grep cachedRW cmd/server/*.go | grep -v _test.go` → 0 matches.
