efitenandClaude Opus 5 a5aa3cdc41 perf(db): refresh SQLite planner statistics with a bounded ANALYZE (#2058) (#2072)
Closes #2058.

`ANALYZE` has never run against these databases, so `sqlite_stat1` does
not exist and the planner works from built-in guesses. On the channel
queries it guesses wrong: it drives from the plain
`idx_transmissions_payload_type` instead of `idx_tx_channel_hash`, the
partial index (`WHERE payload_type = 5`) the schema already carries for
that exact filter.

@anieto's report did the diagnosis and the arithmetic. This adds the
maintenance operation that was missing, at a value measured rather than
assumed.

## The diagnosis transfers, the remedy needed measuring

Measured on our 9.4 GB staging database: 1,250,489 transmissions,
14,169,329 observations, 2.7x and 7x the reported database.
Region-filtered `GetChannels` produces the identical plan reported in
#2058, down to both temp b-trees, so the problem is the same one.

Wall time is the wrong metric here. The same query and the same plan
measure **56.7s cold and 0.80s warm** on that file, so the OS page cache
dominates. Counting page-cache misses instead:

| analysis_limit | ANALYZE | driving index | page misses |
|---|---|---|---|
| none (no statistics) | - | `idx_transmissions_payload_type` | 143,442
|
| 400 | 171 ms | `idx_transmissions_payload_type` | 143,449 |
| 1000 | 171 ms | `idx_transmissions_payload_type` | 143,450 |
| **10000** | **2.0 s** | **`idx_tx_channel_hash`** | **107,429** |
| 0 (unbounded) | 242.9 s | `idx_tx_channel_hash` | 107,429 |

400, the value SQLite's documentation offers for the bounded form,
changes nothing on this data: it samples too few rows to separate the
126,336-row partial index from the 920,700-row plain one. 10000 buys the
entire plan change for 2.0 s, and the four-minute unbounded `ANALYZE`
buys nothing beyond it.

## What it is worth, as measured

25% fewer pages read per query, 143,442 to 107,429, about 147 MB less at
a 4 KB page. Warm wall time does not move: 0.80s either way. The gain
lands on the cold path, the one that measured 56.7s, so the claim here
is fewer pages read, not a warm speedup.

This is smaller and differently shaped than the 3-4x in #2058. I cannot
reproduce that ratio on a database of this size and am not claiming it.

## The change

- `Store.RefreshPlannerStats(analysisLimit)` in `cmd/ingestor/db.go`:
`PRAGMA analysis_limit=N` then `ANALYZE`, logging the duration and
whether this was the first run.
- Wired in `cmd/ingestor/main.go` next to the existing WAL checkpoint
ticker: 24h, staggered 2 minutes past startup because it takes the write
lock.
- `db.analysisLimit` in `internal/dbconfig`, default 10000, negative
disables it.

It runs in the ingestor, not the server: `cmd/server/db.go:145` opens
`mode=ro`, and `ANALYZE` writes. This respects the read/write separation
invariant in AGENTS.md.

`analysis_limit=0` means *no* limit to SQLite rather than "use a
default", so an unset config maps to 10000 and a test covers that
specific case.

## Two faults the measurement caught in my own first commit

Both are in the history rather than hidden, because the second commit is
the one that measured:

1. **`PRAGMA optimize` was the wrong statement.** It analyzes only
tables the calling connection has itself queried during the session, and
a maintenance call has queried none. Run against staging it wrote
nothing and left `sqlite_stat1` absent; `PRAGMA optimize(0x03)` returned
no statements at all. Verified on an empty database too (SQLite 3.45.1):
`ANALYZE` creates `sqlite_stat1`, `PRAGMA optimize` does not. That
difference is what makes the behavioural test a guard instead of a
no-op.
2. **`analysis_limit=400` was the wrong value**, per the table above.

## Tests

Six cases in `cmd/ingestor/refresh_planner_stats_test.go`:

- statistics are actually written (the guard against returning to
`PRAGMA optimize`)
- the pragma reaches the connection, read back through `PRAGMA
analysis_limit`
- a negative limit leaves `sqlite_stat1` absent
- two consecutive refreshes, since a ticker calls this repeatedly
- the config default and the JSON round trip
- the default is above the range measured ineffective, so lowering it
back to 400 fails

## Not done, and one caveat

- **Correction to an earlier version of this description**, which said
the Go tests could not run locally because this box has no C compiler.
That was wrong: `CGO_ENABLED=0` and `gcc` being absent from `PATH` is
not the same as no compiler, and a mingw-w64 toolchain is installed
here. Run properly, all six tests pass locally, and so does the rest of
`cmd/ingestor` apart from
`TestWriteStatsAtomic_SymlinkAtDestIsReplaced`, which fails on
`os.Symlink` with "A required privilege is not held by the client" on
Windows without elevation and lives in `stats_file_test.go`, a file this
branch does not touch. CI agrees: Go Build & Test and the ingestor race
detector are both green.
- The SQLite behaviours above were measured against 3.45.1 on the
server, not against the amalgamation `mattn/go-sqlite3` bundles.
- **No query rewrite.** #2058 explicitly left that out and so does this;
the correctness caveats it lists (per-channel most-recent-message
semantics, v2/v3 branches, `enc_` exclusion) are untouched here.
- Staging carries limit-10000 statistics, matching what this code
produces. Reversible: `DROP TABLE sqlite_stat1` was verified on a
scratch database before any of it ran.
- Whether a cold-start `ANALYZE` should also run before the 2 minute
stagger is not addressed. The first query after a restart is the
expensive one, and it can arrive first.

Sylvain Rabot a2ea18f778 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 ac7e8d38. Passing tests
did not establish safety here, which is why the deletion path wanted a
second pair of eyes rather than a rubber stamp.

efitenandSaarMesh-Bot 9d6f08c144 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.

40f664c587 chore(#1859): gofmt sweep + gofmt/go vet CI gate (rebase of #1881) (#1941)
Rebase of #1881 by @SaarMesh-Bot onto current master. Their three
commits are preserved, two of them cherry-picked with authorship intact;
the sweep itself had to be regenerated. Opened as a new PR rather than
force-pushing their branch.

Closes #1881 once merged. Addresses parts 1 and 3 of #1859; part 2
landed as #1937.

## Why regenerated rather than merged

The sweep in #1881 was cut on 2026-09-02 07:13 and roughly forty PRs
landed after it, so it went `CONFLICTING/DIRTY`. Re-running `gofmt` on
current master is cheaper and less error-prone than resolving 72
conflicts that are all whitespace. The drift it fixes also grew in the
meantime: 66 files now, against 72 then, but spread differently.

## The three commits

1. **`style(#1859)`** — `gofmt -w` across the 14 modules. 66 files.
2. **`test(#1859)`** — @SaarMesh-Bot's fix for the one `go vet`
copylocks finding, `cmd/ingestor/coverage_boost_test.go`: the range
variable copied a `Config` embedding `sync.Once`. Cherry-picked
unchanged.
3. **`ci(#1859)`** — @SaarMesh-Bot's CI step that fails on gofmt drift
or vet findings, plus `.git-blame-ignore-revs`. Cherry-picked with one
change, noted in the commit message: the ignore file pointed at
`04bc80ee`, the sweep commit on their branch, which does not exist on
this base and would make `git blame --ignore-revs-file` error. Repointed
at `d3a02599`, the sweep here.

## Verification

The claim "formatting only" is checked twice rather than asserted:

- Every changed file is byte-identical to `gofmt(previous content)`. 0
of 66 deviate.
- With line comments and all whitespace stripped, 0 of 66 files differ,
so no code outside comments changed.

14 of the 66 also show doc-comment reflow. Since Go 1.19 `gofmt`
re-indents indented comment blocks to tabs and inserts a blank comment
line before them; the behavior matrix above `resolveHopWithContext` in
`cmd/ingestor/path_resolver.go` is a clear example. That is gofmt's own
output, not an edit, but it is worth naming because it makes the diff
look larger than "whitespace" suggests.

The gate was run locally exactly as the workflow runs it: `gofmt` clean,
and `go vet` clean in all 14 modules, including `cmd/ingestor` which is
what commit 2 fixes.

Suites: `cmd/server` ok (80.7s), `internal/packetpath` ok (2.3s),
`cmd/ingestor` passes except
`TestWriteStatsAtomic_SymlinkAtDestIsReplaced`, which fails identically
on bare master with "A required privilege is not held by the client"
(Windows symlink privilege on my host, not code).

## Sequencing

This should go last in the queue. The sweep touches 66 files, so merging
it before the remaining open Go PRs gives each of them a conflict about
nothing but formatting. After it lands the gate is active, and any PR
with drift fails CI until it runs `gofmt -w`.

Excluded from the sweep: the misnamed `Dockerfile.go`, which is a
Dockerfile that gofmt cannot parse (the workflow excludes it too), and
`docs/DEPLOYMENT.md`, which a case-insensitive filesystem surfaces as a
spurious modification against `docs/deployment.md` and is unrelated.

efitenandJonathan Herlin 89544b1d08 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.

efitenandClaude Opus 5 176bb53335 fix(#1784): ship pathTrust default 1, not 2 (#1929)
Follows #1841. Moves the pathTrust default from 2 back to 1.

## Why

#1784's first acceptance criterion is **"Default behaviour remains
backward-compatible"**, and its example config shows
`minHashBytesForMapping: 1`. What shipped is 2.

The problem is not the value. It is that **there is no way to undo it
from the UI.** #1841 adds no control for the threshold: it is
`config.json` only, and changing it needs a restart. The customizer
gains a hint that says exactly that. So an instance that upgrades
without touching config switches to the stricter rule, and the only
visible symptom is that the neighbour graph and the resolved paths
quietly get smaller.

The existing "Hide 1-byte path hops" toggle (#1633) is a *display*
filter and does not change what counts as evidence, so it is not an
escape hatch either. The two are easy to confuse.

## How much this actually moves

Measured on a live instance via `/api/analytics/hash-sizes`, not
estimated:

| path-hop observations | count | share |
|---|---|---|
| 1-byte prefix | 116,923 | **56.0%** |
| 2-byte prefix | 86,031 | 41.2% |
| 3-byte prefix | 5,753 | 2.8% |

| repeaters by observed hash size | count |
|---|---|
| 1-byte | **645 (41%)** |
| 2-byte | 865 |
| 3-byte | 63 |

At threshold 2 the 1-byte column stops counting as mapping evidence.
`MeetsPathTrust` also drops the legacy bucket-0 observations with it
(pre-#1638 persisted neighbor edges that carry no per-mode breakdown),
so already-stored edges lose their evidence status on upgrade too.

## What this does not change

The knob works and is untouched. Operators who want the stricter
behaviour set `minHashBytesForMapping` to 2 or 3, which is the opt-in
#1784 describes. Only the default moves. Nothing about storage changes;
packets and paths were never affected either way.

## Also fixes an inconsistency inside #1841

Five frontend consumers already fall back to **1** when
`MC_getPathTrustThreshold()` is unavailable: `analytics.js`, `live.js`,
`map.js`, `nodes.js`, `route-view.js`. Two fell back to **2**:
`hop-filter.js` (the getter itself) and `customize-v2.js`. They now all
agree.

## Tests

- `internal/packetpath`: `TestMeetsPathTrust_ZeroValueOptIn` was
asserting the old default *through behaviour*, so it would need
rewriting on any future default change. It now asserts the property
instead: an absent JSON field resolves to
`DefaultMinHashBytesForMapping`, behaves identically to naming that
value outright, and an explicit stricter setting still wins. Package
tests pass.
- `test-issue-1633-hide-1byte-hops.js`: the case pinning the getter's
default is updated, with the reasoning in a comment so the next person
sees why it is 1. **37 passed, 0 failed** (master baseline: 37 passed, 0
failed).
- `cmd/server` config tests pass.

## One thing I want to flag rather than paper over

The test I changed was named `default is 2 (operator-confirmed)`. I am
overriding something that was confirmed with an operator, and I am not
claiming that confirmation was wrong. My reading is that it was about
the threshold being a *useful* value, which it is, rather than about it
being the default in a build with no UI to change it. If the intent
really was "2 out of the box for everyone", say so and I will close
this.

Jesper B 8c48f2b49a feat(#1784): wire display consumers to path trust threshold (#1841)
Fixes #1784

## Summary

Step 4 of the #1784 multi-PR project — wires all frontend display
consumers to respect the configured `pathTrust.minHashBytesForMapping`
value.

**Depends on:** #1840 (must be merged first — provides
`MC_meetsPathTrust` / `MC_pathBelowTrust` / `MC_getPathTrustThreshold`
helpers and `PATH_TRUST` global).

## Changes

### `map.js` — trust-gated route display
- `drawPacketRoute` checks `MC_pathBelowTrust` before drawing polylines
- When all path hops are below the configured threshold, shows a "Route
not displayed" message with config guidance instead of speculative
polylines
- Cleans up the trust message control when a new route is drawn

### `analytics.js` — subpath trust filtering
- `renderTable` in `renderSubpaths` filters route patterns whose hops
are below trust threshold
- Combined filter logic: both the 1-byte hide toggle AND trust threshold
are applied together
- Info line shows which filters are active ("1-byte hide + 2-byte
trust", etc.)
- No-data message explains which filters caused exclusion

### `route-view.js` — speculative path annotation
- Path picker groups tagged with `belowTrust` flag when any hop doesn't
meet the configured threshold
- Speculative paths show `(speculative, <N-byte hops)` annotation with
tooltip explaining the trust threshold
- Tooltip includes guidance on changing
`pathTrust.minHashBytesForMapping` in config.json

### `live.js` — Paths Through widget
- `_pathHopsBelowTrust()` helper checks whether all hops in a path are
below trust threshold
- Widget fallback message distinguishes between "1-byte filtered"
(display toggle) and "N-byte trust threshold" (server config)
- Message includes the config key for operators to adjust

### `nodes.js` — confidence weight adjustment
- `modeWeight` initialization considers the trust threshold
- Hash modes below threshold get zero confidence weight
- Bucket-0 (legacy/unknown) excluded at threshold >= 2 per #1784
bucket-0 policy

## Testing

`test-issue-1633-hide-1byte-hops.js`:
- 5 new source-grep guards verifying each consumer references the trust
threshold helpers
- All 26 tests passing (21 existing + 5 new)

## Files changed (6 files, +136/-6)

57956712e7 fix(#1768): Relay Airtime Share uses LoRa Time-on-Air (preamble-aware) — partial fix (#1776)
Partial fix for #1768 — Relay Airtime Share now uses closed-form LoRa
Time-on-Air instead of a payload-bytes-only proxy, removing the ~3-4×
bias against small frames (preamble + fixed-symbol intercept).

cross-stack: justified — backend score formula needs a frontend caption
change (`public/analytics.js` dumbbell preset banner + tooltip) so
operators can interpret the assumed PHY block. Both move together or the
metric is misleading.

## Red commit

`8da57062` — failing test asserts ToA-based score (~83.48 % ADVERT share
on the locked acceptance fixture) instead of the byte proxy's 95.24 %.
`internal/lora.TimeOnAir` was a zero-returning stub at the red commit;
tests failed with assertion errors, not build errors.

## Green commit

`dd402edd` — implements `lora.TimeOnAir` (Semtech AN1200.13 / SX126x
§6.1.4 closed form, cross-checked against RadioLib), wires `score =
TimeOnAir(payloadBytes, preset) × distinctRelays` in
`cmd/server/relay_airtime_share.go`, surfaces the preset in the JSON
response and analytics caption.

## Config (per AGENTS Config Documentation Rule)

New keys under existing `analytics` block:

```json
"loraPreset": { "freq": 869600000, "bw": 62.5, "sf": 8, "cr": 5 }
```

Defaults match the deployment's actual `get radio` (869.6 MHz / BW 62.5
kHz / SF 8 / CR 4/5). `CRC=1`, `IH=0`, `DE = (T_sym ≥ 16 ms)`, and the
SF-dependent preamble (32 for SF≤8 else 16, per firmware
`preambleLengthForSF` / MeshCore PR #1954) are firmware-fixed constants
in `internal/lora/toa.go` and intentionally NOT surfaced as config (per
re-triage).

## Scope

In-scope files (6):

- `internal/lora/toa.go` (new package — closed-form ToA)
- `internal/lora/toa_test.go` (table-driven preset tests)
- `cmd/server/relay_airtime_share.go` (wire ToA into score)
- `cmd/server/relay_airtime_share_test.go` (recomputed expected values)
- `cmd/server/config.go` + `config.example.json` (preset config keys)
- `public/analytics.js` (preset caption on dumbbell chart + tooltip)

Plus `cmd/server/go.mod` (replace directive for the new internal
module).

## Deferred to v2 (separate issues per re-triage)

- Per-observation SF/BW + radio-settings-aware dedup (blocked: ingestor
stores SNR/RSSI only, no SF/BW on observations).
- CR-per-hop dual-point sensitivity band (CR scales only the payload
symbol term `(CR+4)`, not the preamble/header; second-order accuracy
gain).
- Cross-SF bridge accounting.

## Tests

```
cd internal/lora && go test ./...           → PASS
cd cmd/server && go test -run RelayAirtime  → PASS
```

## Preflight overrides

- `check-branch-clean` (cross-stack): justified above — score formula
change requires matching caption update; both files trace to the same
issue.

Kpa-clawbotandclawbot e465e1c6c6 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)

048143f54f 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.

Fixes #1690.

a4776557ae 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
f12911dc feat(#1290): exclude listener-only observers from path-hop disambiguator
5f7fdb96 test(#1290): red — assert listener-only observers excluded from path-hop candidates
```

Full server + ingestor + dbschema + migrate test suites pass locally.

## Acceptance checklist (from #1290)

* [x] Ingestor parses `repeat` field (boolean OR string `on|off`)
* [x] Field persisted on `observers` table (new `can_relay BOOLEAN`
column, idempotent migration via `internal/dbschema`)
* [x] Server's disambiguator (`pm.resolveWithContext`) excludes
`can_relay=false` observer-nodes from path-hop candidate set
* [x] UI badge on observers list + node detail page indicating
"listener" vs "repeater"
* [x] Backward compat: legacy observers default to `can_relay=true`
* [x] Test: `repeat:off` → NOT a candidate
* [x] Test: `repeat:on` → IS a candidate
* [x] Test: legacy → IS a candidate

## Out of scope (preserved per issue)

Backfilling already-resolved paths is left as a follow-up. No
firmware/broker changes.

bc1822e46c perf(load): chunked Load with early HTTP readiness (#1009) (#1596)
## What

Switches the server's startup from a synchronous full-scan
`PacketStore.Load()` to a chunked `LoadChunked(chunkSize)` that:

1. Streams transmissions+observations from SQLite in id-ordered chunks
(default `chunkSize=10000`, configurable via `db.load.chunkSize`).
2. Closes `FirstChunkReady()` after the first chunk is merged —
`main.go` binds the HTTP listener on that signal instead of blocking on
the full multi-minute load.
3. Stamps `X-CoreScope-Load-Status: loading; progress=<rows>` on every
response while LoadChunked is in flight, flipping to `ready` once it
completes (via `loadStatusMiddleware`).
4. Preserves the existing retention/`hotStartupHours`/`maxMemoryMB`
clamps and the post-load index rebuild (`pickBestObservation` /
`buildSubpathIndex` / `buildPathHopIndex` / `buildDistanceIndex`).

## Why

Per #1009: at 5M+ observations (Cascadia scale) the synchronous Load
blocked HTTP for ~80s with a 2–3× steady-state RAM peak. With chunked
load the listener binds within seconds; dashboards and probes can read
partial data and see the `loading` status header until the background
load finishes.

## Notes

- `/api/healthz` readiness gate (`readiness` atomic, init `WaitGroup`)
is unchanged — it still waits for neighbor-graph build + initial
`pickBestObservation` before reporting `ready:true`. `LoadChunked` only
changes when the listener BINDS, not when it advertises ready.
- `cmd/server/main.go` waits for `FirstChunkReady` (or the full load on
a tiny DB) before proceeding, and drains the load goroutine in the
background with a logged error path.
- Config Documentation Rule: `config.example.json` now documents
`db.load.chunkSize` with a nested `_comment` describing the trade-off.

## Tests

- `cmd/server/chunked_load_test.go` asserts:
  - (a) `FirstChunkReady` fires before `LoadChunked` returns
- (b) `X-CoreScope-Load-Status` transitions `loading; progress=...` →
`ready`
- (c) `chunkSize` honored (2500 rows @ 1000 → 3 chunks via
`OnChunkLoaded`)
  - (d) `Config.DBLoadChunkSize()` default 10000 + override
- Red commit (`102a4c84`) lands the tests with stubs that fail on
assertion — verified locally before the green commit.
- Green commit (`35cecf16`) makes all four pass; full `cmd/server` suite
green (47s locally).

Closes #1009



## TDD red-commit exemption

The original red commit `f878e15e` ("test(load): failing tests for
chunked Load + early HTTP readiness") fails to **compile** rather than
failing on an assertion, because it references symbols
(`store.LoadChunked`, `store.FirstChunkReady`, `store.OnChunkLoaded`,
`Config.DBLoadChunkSize`, `loadStatusMiddleware`) that do not exist on
master. Per `AGENTS.md` the bar is "MUST fail on an assertion ... A
compile error is NOT a valid red commit."

This is claimed under the **net-new surface** exemption with the
following justification:

- LoadChunked / FirstChunkReady / loadStatusMiddleware / DBLoadChunkSize
are all introduced by this PR — no prior implementation existed to
refactor. There is no behaviour on master that the red commit could
meaningfully assert against without first declaring the new symbols.
- The cheapest "proper" alternative (split the red into two commits:
stub-first + assertion-fail) was deferred because the test file
unambiguously fails on missing-symbol — there is no risk of the test
becoming a tautology against a pre-existing stub.
- **Behaviour gating IS proven elsewhere on this branch.** Commit
`799bde49` ("test(load): red — LoadChunked must mark indexes ready + not
flip Complete on error") is a proper assertion-fail red against the same
package, and commit `92cadd1d` is the matching green. Reviewers can
verify the red→green pattern there.

If a future reviewer wants the strict pattern, the follow-up is
mechanical: split `f878e15e` into a stub-only commit followed by the
assertion commit. Not done here to keep the rework cost proportional to
the risk (zero, in this case).

## Preflight overrides

- check-async-migrations: justified — the flagged `CREATE TABLE`/`CREATE
INDEX` statements live in `cmd/server/chunked_load_id_zero_test.go` and
`cmd/server/chunked_load_oldest_test.go` only. They run against per-test
`t.TempDir()` SQLite files (in-process, ~10 rows, lifetime = single
test) — they are NOT production schema migrations. No prod table is
touched. PREFLIGHT-MIGRATION-SCALE: <30s N=10 (per-test tempdir
fixture).

Kpa-clawbotandopenclaw 43b93c6bb9 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).

Closes #1478.

0b35c7eef3 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

c7ab5f3eb9 fix(#1366): channels view shows latest message time — backend emits LatestSeen, not FirstSeen (#1368)
Red commit: 702d82eb5e (CI: see Actions
tab for fix/issue-1366)

## What
Channel view emits the max observation timestamp (`tx.LatestSeen`)
instead of the analyzer's first-observation time (`tx.FirstSeen`) as the
rendered `timestamp` field. A new `first_seen` field is exposed
alongside for debug surfaces. `sender_timestamp` continues to be
returned in the JSON response but is intentionally NOT used as the
rendered time (client clocks are unreliable).

## Root cause

Two parallel call sites both emitted the wrong field:

- `cmd/server/store.go` — `GetChannelMessages` (~line 4807): set
`entry.Data["timestamp"] = strOrNil(tx.FirstSeen)` for every new dedup
entry. `tx.FirstSeen` is the analyzer's first-ever observation time of a
`transmissions.hash` row; for heartbeat-style packets (e.g. `BlorkoBot
🤖` posting the same status line periodically), the hash is stable, so
FirstSeen stays pinned at the very first observation while the message
keeps retransmitting hours later. Operator sees "old" message timestamps
for live messages.
- `cmd/server/db.go` — `GetChannelMessages` (~line 1757): same problem
against the SQLite-backed query path. Used `nullStr(fs)` (where `fs` is
`t.first_seen`) for the `timestamp` field.

### Repro from staging
Same packet, same hash `aba4f0493249de57`, sender `BlorkoBot 🤖`:
- `/api/channels/%23test/messages` → `timestamp: "2026-05-25T15:53:20Z"`
(FirstSeen, 7h+ in the past)
- `/api/packets?hash=aba4f0493249de57` → `first_seen:
"2026-05-25T22:53:19Z"` (latest obs), `observation_count: 84`

The packets view used max-obs correctly; the channels view did not. 7h
gap matches operator screenshot.

## TDD red → green

Red: `cmd/server/channels_message_order_1366_test.go` — three tests:
- `TestChannelMessages_TimestampUsesLatestSeen`: seeds a CHAN tx with
observations 7h apart, asserts returned `timestamp` ≈ latest observation
epoch (±1s). Fails under FirstSeen with Δ=−25200s.
- `TestChannelMessages_TimestampNotSenderTimestamp`: seeds a CHAN tx
whose decoded `sender_timestamp` is year-2000 (bad RTC). Asserts the
rendered `timestamp` parses to current year — guards against the
tempting "just use sender_timestamp" alt-fix that would let bad client
clocks corrupt the view.
- `TestChannelMessages_TimestampIsUTCZ`: asserts the emitted string is
unambiguously UTC (suffix `Z` or `+00:00`) so browsers don't apply a
local-zone shift.

Green commit changes:
- `store.go`: emit `tx.LatestSeen` (with FirstSeen fallback if no obs);
add `first_seen` field.
- `db.go`: join `o.timestamp` per-observation, track max epoch per tx,
emit RFC3339 UTC at the end; add `first_seen` field.

`sender_timestamp` remains in the response — unchanged shape, frontend
never read it for the rendered time (verified: only `msg.timestamp` is
consumed in `public/channels.js:1902`).

## Manual verification (post-merge)

1. Deploy to staging.
2. Curl `/api/channels/%23test/messages?limit=5` and
`/api/packets?hash=<recent>`. The channel `timestamp` field MUST equal
the packets `first_seen` (max obs) for the same hash, NOT lag it.
3. Send a fresh GRP_TXT via a MeshCore client into a watched channel.
Within 15s, refresh the Channels view at `/channels`. The new message
MUST render at the bottom with the correct (current) time.

## Why not `sender_timestamp`?

It's a per-client field, decoded from the payload. Many MeshCore
firmware builds run without RTC/NTP/GPS and report bogus values.
Trusting it for display would propagate bad client clocks into the
analyzer UI — the analyzer is the source of truth for UTC, not the
client.

Fixes #1366

Kpa-clawbotandopenclaw-bot d9ba9937a6 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.

efitenandClaude Sonnet 4.6 51f823bf7e feat: one-click prune nodes outside geofilter (#669 M4) (#738)
## Summary

- Adds `POST /api/admin/prune-geo-filter` endpoint — dry-run by default,
`?confirm=true` to permanently delete nodes outside the current
geofilter polygon + buffer. Requires `X-API-Key` header.
- Adds **Prune nodes** section inside the GeoFilter customizer tab
(write-access only, same `writeEnabled` gate as PUT). **Preview** lists
affected nodes; **Confirm delete** removes them.
- Adds `GetNodesForGeoPrune` and `DeleteNodesByPubkeys` DB helpers.
- Updates `docs/user-guide/geofilter.md` — documents the UI button as
primary workflow, CLI script as alternative.

> **Depends on M3** (`feat/geofilter-m3-customizer`, PR #736). Merge M3
first.

## Test plan

- [x] `cd cmd/server && go test ./...` — all pass
- [x] Customizer GeoFilter tab without `apiKey` — Prune section not
visible
- [x] With `apiKey` + polygon active — Prune section visible
- [x] **Preview** returns list of nodes outside polygon (no deletions)
- [x] **Confirm delete** removes nodes, list clears
- [x] `POST /api/admin/prune-geo-filter` without `X-API-Key` → 401
- [x] `POST /api/admin/prune-geo-filter` with no polygon configured →
400

9383201c07 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.

Fixes #1287.

f4cf2acbc0 perf: cancelled writes + ingestor I/O + threshold tests (#1120 follow-up) (#1167)
Red commit: e964ec9c46 (CI run: pending —
workflow only triggers on PR open)

Partial fix for #1120 — finishes the four follow-up items left open
after PR #1123 (cancelled writes, ingestor I/O, threshold-flag tests,
docs).

## What's done

- **`cancelledWriteBytesPerSec`** — server `/proc/self/io` parser
handles `cancelled_write_bytes`; `/api/perf/io` exposes the per-second
rate; Perf page renders it next to Read/Write with ⚠️ when sustained >1
MB/s.
- **Ingestor `/proc/<pid>/io`** — `cmd/ingestor/stats_file.go` samples
its own `/proc/self/io` each tick and includes `procIO` in the snapshot.
The server's `/api/perf/io` reads it and surfaces `.ingestor`. Frontend
renders an `Ingestor process` Disk I/O block alongside the existing
`server process` block (issue mockup: "Both ingestor and server").
- **Threshold + anomaly tests** — `test-perf-disk-io-1120.js` now
asserts ⚠️ fires/suppresses on WAL>100MB, cache_hit<90%, and the
backfill-rate-vs-tx-rate guard with the `tx_inserted >= 100` baseline
floor. Drops the tautological `|| ... === false` short-circuits flagged
in MINOR m4.
- **Docs (m8)** — `config.example.json` adds `_comment_ingestorStats`
(env var, default path, shared-tmp security note);
`cmd/ingestor/README.md` adds `CORESCOPE_INGESTOR_STATS` to the env-var
table plus a `Stats file` section.

## What's NOT done (deferred)

m1 sync.Map → map+RWMutex, m2 perfIOMu rate caching, m3 negative
cacheSize translation, m5 deterministic-write test, m7 ctx-aware
shutdown — pure polish; will file a follow-up issue if the operator
wants them tracked.

## TDD

- Red: `e964ec9` — adds failing tests + stub field/handler shape
(cancelled missing from struct, ingestor stub returns nil, ingestor
procIO absent).
- Green: `1240703` — wires up the parser case, ingestor sampler,
frontend rendering, docs.

E2E assertion added: test-perf-disk-io-1120.js:108

Kpa-clawbotandyou dd2f044f2b fix: cache RW SQLite connection + dedup DBConfig (closes #921) (#982)
Closes #921

## Summary

Follow-up to #920 (incremental auto-vacuum). Addresses both items from
the adversarial review:

### 1. RW connection caching

Previously, every call to `openRW(dbPath)` opened a new SQLite RW
connection and closed it after use. This happened in:
- `runIncrementalVacuum` (~4x/hour)
- `PruneOldPackets`, `PruneOldMetrics`, `RemoveStaleObservers`
- `buildAndPersistEdges`, `PruneNeighborEdges`
- All neighbor persist operations

Now a single `*sql.DB` handle (with `MaxOpenConns(1)`) is cached
process-wide via `cachedRW(dbPath)`. The underlying connection pool
manages serialization. The original `openRW()` function is retained for
one-shot test usage.

### 2. DBConfig dedup

`DBConfig` was defined identically in both `cmd/server/config.go` and
`cmd/ingestor/config.go`. Extracted to `internal/dbconfig/` as a shared
package; both binaries now use a type alias (`type DBConfig =
dbconfig.DBConfig`).

## Tests added

| Test | File |
|------|------|
| `TestCachedRW_ReturnsSameHandle` | `cmd/server/rw_cache_test.go` |
| `TestCachedRW_100Calls_SingleConnection` |
`cmd/server/rw_cache_test.go` |
| `TestGetIncrementalVacuumPages_Default` |
`internal/dbconfig/dbconfig_test.go` |
| `TestGetIncrementalVacuumPages_Configured` |
`internal/dbconfig/dbconfig_test.go` |

## Verification

```
ok  github.com/corescope/server    20.069s
ok  github.com/corescope/ingestor  47.117s
ok  github.com/meshcore-analyzer/dbconfig  0.003s
```

Both binaries build cleanly. 100 sequential `cachedRW()` calls return
the same handle with exactly 1 entry in the cache map.

Kpa-clawbotandyou 56ec590bc4 fix(#886): derive path_json from raw_hex at ingest (#887)
## Problem

Per-observation `path_json` disagrees with `raw_hex` path section for
TRACE packets.

**Reproducer:** packet `af081a2c41281b1e`, observer `lutin🏡`
- `path_json`: `["67","33","D6","33","67"]` (5 hops — from TRACE
payload)
- `raw_hex` path section: `30 2D 0D 23` (4 bytes — SNR values in header)

## Root Cause

`DecodePacket` correctly parses TRACE packets by replacing `path.Hops`
with hop IDs from the payload's `pathData` field (the actual route).
However, the header path bytes for TRACE packets contain **SNR values**
(one per completed hop), not hop IDs.

`BuildPacketData` used `decoded.Path.Hops` to build `path_json`, which
for TRACE packets contained the payload-derived hops — not the header
path bytes that `raw_hex` stores. This caused `path_json` and `raw_hex`
to describe completely different paths.

## Fix

- Added `DecodePathFromRawHex(rawHex)` — extracts header path hops
directly from raw hex bytes, independent of any TRACE payload
overwriting.
- `BuildPacketData` now calls `DecodePathFromRawHex(msg.Raw)` instead of
using `decoded.Path.Hops`, guaranteeing `path_json` always matches the
`raw_hex` path section.

## Tests (8 new)

**`DecodePathFromRawHex` unit tests:**
- hash_size 1, 2, 3, 4
- zero-hop direct packets
- transport route (4-byte transport codes before path)

**`BuildPacketData` integration tests:**
- TRACE packet: asserts path_json matches raw_hex header path (not
payload hops)
- Non-TRACE packet: asserts path_json matches raw_hex header path

All existing tests continue to pass (`go test ./...` for both ingestor
and server).

Kpa-clawbotandyou c233c14156 feat: CLI tool to decrypt and export hashtag channel messages (#724)
## Summary

Adds `corescope-decrypt` — a standalone CLI tool that decrypts and
exports MeshCore hashtag channel messages from a CoreScope SQLite
database.

### What it does

MeshCore hashtag channels use symmetric encryption with keys derived
from the channel name. The CoreScope ingestor stores **all** GRP_TXT
packets, even those it can't decrypt. This tool enables retroactive
decryption — decrypt historical messages for any channel whose name you
learn after the fact.

### Architecture

- **`internal/channel/`** — Shared crypto package extracted from
ingestor logic:
  - `DeriveKey()` — `SHA-256("#name")[:16]`
  - `ChannelHash()` — 1-byte packet filter (`SHA-256(key)[0]`)
  - `Decrypt()` — HMAC-SHA256 MAC verify + AES-128-ECB
  - `ParsePlaintext()` — timestamp + flags + "sender: message" parsing

- **`cmd/decrypt/`** — CLI binary with three output formats:
  - `--format json` — Full metadata (observers, path, raw hex)
  - `--format html` — Self-contained interactive viewer with search/sort
  - `--format irc` (or `log`) — Plain-text IRC-style log, greppable

### Usage

```bash
# JSON export
corescope-decrypt --channel "#wardriving" --db meshcore.db

# Interactive HTML viewer
corescope-decrypt --channel wardriving --db meshcore.db --format html --output wardriving.html

# Greppable log
corescope-decrypt --channel "#wardriving" --db meshcore.db --format irc | grep "KE6QR"

# From Docker
docker exec corescope-prod /app/corescope-decrypt --channel "#wardriving" --db /app/data/meshcore.db
```

### Build & deployment

- Statically linked (`CGO_ENABLED=0`) — zero dependencies
- Added to Dockerfile (available at `/app/corescope-decrypt` in
container)
- CI: builds and tests in go-test job
- CI: attaches linux/amd64 and linux/arm64 binaries to GitHub Releases
on tags

### Testing

- `internal/channel/` — 9 tests: key derivation, encrypt/decrypt
round-trip, MAC rejection, wrong-channel rejection, plaintext parsing
- `cmd/decrypt/` — 7 tests: payload extraction, channel hash
consistency, all 3 output formats, JSON parseability, fixture DB
integration
- Verified against real fixture DB: successfully decrypts 17
`#wardriving` messages

### Limitations

- Hashtag channels only (name-derived keys). Custom PSK channels not
supported.
- No DM decryption (asymmetric, per-peer keys).
- Read-only database access.

Fixes #723

copelajeandyou 922ebe54e7 BYOP Advert signature validation (#686)
For BYOP mode in the packet analyzer, perform signature validation on
advert packets and display whether successful or not. This is added as
we observed many corrupted advert packets that would be easily
detectable as such if signature validation checks were performed.

At present this MR is just to add this status in BYOP mode so there is
minimal impact to the application and no performance penalty for having
to perform these checks on all packets. Moving forward it probably makes
sense to do these checks on all advert packets so that corrupt packets
can be ignored in several contexts (like node lists for example).

Let me know what you think and I can adjust as needed.

efitenandClaude Sonnet 4.6 fe314be3a8 feat: geo_filter enforcement, DB pruning, geofilter-builder tool, HB column (#215)
## Summary

Several features and fixes from a live deployment of the Go v3.0.0
backend.

### geo_filter — full enforcement

- **Go backend config** (`cmd/server/config.go`,
`cmd/ingestor/config.go`): added `GeoFilterConfig` struct so
`geo_filter.polygon` and `bufferKm` from `config.json` are parsed by
both the server and ingestor
- **Ingestor** (`cmd/ingestor/geo_filter.go`, `cmd/ingestor/main.go`):
ADVERT packets from nodes outside the configured polygon + buffer are
dropped *before* any DB write — no transmission, node, or observation
data is stored
- **Server API** (`cmd/server/geo_filter.go`, `cmd/server/routes.go`):
`GET /api/config/geo-filter` endpoint returns the polygon + bufferKm to
the frontend; `/api/nodes` responses filter out any out-of-area nodes
already in the DB
- **Frontend** (`public/map.js`, `public/live.js`): blue polygon overlay
(solid inner + dashed buffer zone) on Map and Live pages, toggled via
"Mesh live area" checkbox, state shared via localStorage

### Automatic DB pruning

- Add `retention.packetDays` to `config.json` to delete transmissions +
observations older than N days on a daily schedule (1 min after startup,
then every 24h). Nodes and observers are never pruned.
- `POST /api/admin/prune?days=N` for manual runs (requires `X-API-Key`
header if `apiKey` is set)

```json
"retention": {
  "nodeDays": 7,
  "packetDays": 30
}
```

### tools/geofilter-builder.html

Standalone HTML tool (no server needed) — open in browser, click to
place polygon points on a Leaflet map, set `bufferKm`, copy the
generated `geo_filter` JSON block into `config.json`.

### scripts/prune-nodes-outside-geo-filter.py

Utility script to clean existing out-of-area nodes from the database
(dry-run + confirm). Useful after first enabling geo_filter on a
populated DB.

### HB column in packets table

Shows the hop hash size in bytes (1–4) decoded from the path byte of
each packet's raw hex. Displayed as **HB** between Size and Type
columns, hidden on small screens.

## Test plan

- [x] ADVERT from node outside polygon is not stored (no new row in
nodes or transmissions)
- [x] `GET /api/config/geo-filter` returns polygon + bufferKm when
configured, `{polygon: null, bufferKm: 0}` when not
- [x] `/api/nodes` excludes nodes outside polygon even if present in DB
- [x] Map and Live pages show blue polygon overlay when configured;
checkbox toggles it
