## Partial fix for #1128 — closes the gaps PR #1131 left behind
PR #1131 was a partial fix for the packets-page layout chaos
(merged 2026-05-06 ~01:55 UTC, then the issue was reopened by the
maintainer). #1131 shipped Bug 4 (`--surface` definition), the
`.path-popover` flip + lower z-index, the debounced re-measure for
Bug 1, the `.filter-bar` row-gap + `.multi-select-trigger`
truncation for Bug 3, the new z-index TOKENS, and a single-viewport
E2E with five individual-component assertions.
This PR closes everything else the issue body and the
`specs/packets-layout-audit.md` audit asked for.
### What changed (per gap)
**Gap A — apply the z-index scale (audit Section 2)**
#1131 added `--z-dropdown` / `--z-popover` / `--z-modal` /
`--z-tooltip` but explicitly left existing literal values in place.
This PR renumbers the 7 dropdowns/popovers the audit named:
| Selector | Before | After |
|---|---:|---:|
| `.col-toggle-menu` | 50 | `var(--z-dropdown)` (100) |
| `.multi-select-menu` | 90 | `var(--z-dropdown)` |
| `.region-dropdown-menu` | 90 | `var(--z-dropdown)` |
| `.node-filter-dropdown` | 100 | `var(--z-dropdown)` |
| `.fux-saved-menu` | `var(--z-tooltip)` (9200) | `var(--z-dropdown)` |
| `.fux-ac-dropdown` | `var(--z-tooltip)` | `var(--z-dropdown)` |
| `.hop-conflict-popover` | `var(--z-tooltip)` | `var(--z-popover)`
(300) |
`.fux-ctx-menu` deliberately retains the tooltip band — context
menus must float above all toolbar UI. `.region-filter-options-menu`
no longer exists in the source (was renamed
`.region-dropdown-menu`).
The `style.css` doc-block at the top is rewritten to record the
applied scale and to point operators at the new lint.
**Gap B — CSS-var lint (audit Section 5 #1, "single highest-value
addition")**
Adds `scripts/check-css-vars.js` (~70 lines). Walks
`public/*.css`, extracts every `var(--name)` reference WITHOUT a
fallback, asserts the name is defined in some `public/*.css`.
References WITH a fallback are tolerated. Wired into CI in the
`go-test` job before the JS unit tests.
The red commit (`608d81f`) shipped this lint exiting 1 against the
master tree — three undefined vars that bypassed earlier review:
```
public/style.css:2628 var(--text-primary)
public/style.css:2675 var(--bg-hover)
public/style.css:2924 var(--primary)
```
The green commit (`1369d1e`) defines those three as aliases in the
:root block (`--text-primary` → `--text`, `--bg-hover` →
`--hover-bg`, `--primary` → `--accent`). Light + dark themes
inherit through the existing tokens.
**Gap C — multi-viewport E2E (issue acceptance criterion)**
Adds `test-issue-1128-multi-viewport-e2e.js` — sister of the
existing single-viewport test. At each of three viewports
(1280×900, 1080×800, 768×1024):
- takes a screenshot to `e2e-screenshots/issue-1128-<viewport>.png`
- asserts no two `.filter-group` siblings vertically overlap
- on desktop+laptop, opens the Saved menu and the Types
multi-select and asserts the dropdown does not vertically
overlap any `.filter-group` below it
Plus three viewport-agnostic assertions:
- dropdown selectors compute z-index in `[100,199]`
(`.col-toggle-menu`, `.multi-select-menu`,
`.region-filter-options-menu`, `.fux-saved-menu`,
`.fux-ac-dropdown`)
- `.path-hops .hop / .hop-named / .arrow` compute
`line-height ≤ 18px`
- `.col-path` computes `height ≤ 28px`
Wired into the e2e-test job after the existing #1128 test.
**Gap D — Bug 5 polish (toolbar reorder)**
Audit Section 3 Bug 5: swaps `filter-group-dropdowns` and
`filter-group-toggles` in `public/packets.js` so time range +
Group by Hash + ★ My Nodes sit next to the search input. Pure
markup reorder. No CSS / no JS-handler changes.
**Gap E — Bug 1 belt-and-suspenders**
Audit Section 3 Bug 1 sub-bullets:
- locks `.path-hops .hop / .hop-named / .arrow` to
`line-height: 18px` so a chip with mixed font metrics cannot
overflow the 22px host vertically and bleed into the row above
- converts `.col-path { max-height: 28px }` → `height: 28px`
because browsers widely ignore `max-height` on `<td>`s; the
earlier rule was a no-op
### TDD discipline (red → green)
```
$ git log --oneline origin/master..HEAD
68b0426 fix(#1128): Bug 5 — toolbar group reorder (toggles before dropdowns)
6d16e6f fix(#1128): apply z-index scale to dropdowns + Bug 1 chip line-height lock
b9850c9 fix(check-css-vars): strip /* ... */ comments before scanning
1369d1e fix(#1128): define --text-primary, --bg-hover, --primary aliases (lint green)
0d4660f test(#1128): multi-viewport E2E + wire CSS-var lint into CI (red commit)
608d81f test(#1128): add scripts/check-css-vars.js — fails on 3 undefined vars (red commit)
```
Both red commits (`608d81f`, `0d4660f`) were verified to fail
locally before the green commits landed:
- `608d81f` runs the lint and exits 1 on the three undefined vars
listed above (proven against master).
- `0d4660f` introduces the multi-viewport E2E and wires the lint
into CI — the lint then fails the build on master, and the E2E
z-scale assertion fails because pre-fix `.col-toggle-menu` is
50, the multi-selects are 90, etc.
### Acceptance criteria status
From the original issue body:
- ✅ Bug 4 root cause fixed (#1131 + this PR's lint guard)
- ✅ Bug 1 chip-spill (debounced re-measure from #1131 +
line-height lock + col-path height fix from this PR)
- ✅ Bug 2 +N popover positioning (#1131)
- ✅ Bug 3 toolbar overlap (#1131 + #1131 row-gap)
- ✅ Bug 5 group reorder (this PR)
- ✅ Z-index scale documented + applied (this PR)
- ✅ E2E screenshots at multiple viewports (this PR)
- ✅ Bounding-rect collision detection on visible interactive
elements (this PR — `.filter-group` siblings + dropdown vs.
toolbar)
- ✅ CSS-var lint in CI (this PR)
### Why this is "Partial fix for #1128", not "Fixes #1128"
Per `AGENTS.md` rule 34, automated closure is reserved for the
operator after they verify on staging. The acceptance criteria
above appear satisfied in code, but the user should confirm the
visual outcome on staging before closing.
### Files changed
- `scripts/check-css-vars.js` (new — ~70 lines)
- `test-issue-1128-multi-viewport-e2e.js` (new)
- `.github/workflows/deploy.yml` (lint step + e2e step wiring)
- `public/style.css` (z-renumber, doc-block, Bug 1 polish, alias defs)
- `public/packets.js` (Bug 5 reorder)

## Adds new logo and home hero
Replaces the navbar mushroom emoji + "CoreScope" text spans with the new
CoreScope SVG mark, and adds a hero SVG (with the MESH ANALYZER tagline)
above the home page H1.
### What changed
- `public/img/corescope-logo.svg` — navbar mark, no tagline (locked
"aggressive low-amp chirp" variant: facing-arcs + low-amp chirp
connector between the two nodes).
- `public/img/corescope-hero.svg` — home hero version, includes the MESH
ANALYZER tagline.
- `public/index.html` — replaces `<span class="brand-icon">🍄</span><span
class="brand-text">CoreScope</span>` with `<img class="brand-logo"
src="img/corescope-logo.svg?__BUST__" …>`. `.nav-brand` link still
routes to `#/`. `.live-dot` retained.
- `public/style.css` — adds `.brand-logo { height: 36px }` (32px on
tablet ≤900px). Existing 52px nav height unchanged.
- `public/home.js` / `public/home.css` — adds `<img
class="home-hero-logo">` above the hero `<h1>`, sized `max-width:
min(720px, 90vw)` and centered.
### TDD
Red→green is visible in the branch:
- `3159b82` — `test(logo): add failing E2E …` (red commit). Adds
`test-logo-rebrand-e2e.js` and wires it into the `e2e-test` job in
`deploy.yml` with `CHROMIUM_REQUIRE=1`. On this commit `index.html`
still has the emoji + text spans, `home.js` has no hero img, and the SVG
asset files do not exist — the test asserts on each so CI fails on
assertion.
- `19434e1` — `feat(logo): wire new CoreScope SVG logo …` (green
commit). Implements the fix.
### E2E asserts
1. `.nav-brand img` exists with `src` ending `corescope-logo.svg`
2. legacy `.brand-icon` / `.brand-text` are gone
3. `.live-dot` is present, visible, and to the right of the logo (no
overlap)
4. `.home-hero img.home-hero-logo` exists with `src` ending
`corescope-hero.svg`, positioned BEFORE the `<h1>`
5. both `/img/corescope-{logo,hero}.svg` return 200 with svg
content-type
### Customizer compatibility
- `customize.js` still does `querySelector('.brand-text')` /
`.brand-icon` for live branding updates. Both now return `null`;
existing `if (el)` guards make those branches silent no-ops. **No JS
errors, but the customizer's `branding.siteName` and `branding.logoUrl`
fields no longer rewrite the navbar brand** — the brand is now a fixed
SVG asset.
- **Theme accent does NOT recolor the SVG.** SVGs loaded via `<img src>`
are isolated documents and cannot inherit document CSS variables; the
SVG falls back to its embedded brand colors. This is appropriate for a
brand mark; if recoloring per theme is desired later, swap to inline SVG
(separate PR).
### Browser validation
Local Chromium not available in this env; the E2E test soft-skips
locally and hard-fails in CI (`CHROMIUM_REQUIRE=1`). Server-side checks
done locally:
- `curl http://localhost:13581/` → confirmed `<img class="brand-logo"
src="img/corescope-logo.svg?<bust>" …>` rendered, no
`.brand-icon`/`.brand-text` spans.
- `curl -I /img/corescope-logo.svg` and `/img/corescope-hero.svg` → both
200.
### Performance
No hot-path changes. Two new static SVG assets (~7.6KB each), served
directly by the Go static handler. Cache-busted via `?__BUST__`
(auto-replaced server-side).

## v3.7.2 — Hotfix Release
Hotfix release branched from `v3.7.1`. Cherry-picks **only** PR #1121
(ingestor infinite-loop fix). Top-of-master has unresolved issues per
recent operator reports — `release/v3.7.2` is the minimal safe upgrade.
### What's in this branch
- `c788319` — `fix(ingestor): exclude path_json='[]' rows from backfill
WHERE (#1119) (#1121)` (cherry-picked from master)
- `a91f1db` — `chore(release): v3.7.2` (CHANGELOG entry)
### Diff vs `v3.7.1`
```
cmd/ingestor/db.go | 4 +-
cmd/ingestor/db_test.go | 157 +++++++++++++++++++++++++++++++++++++++++++++++-
CHANGELOG.md | 7 +++
```
### What this is NOT
- Not a merge to `master`. Master has moved forward independently with
changes that are not yet ready for release.
- Not a "Fixes #X" PR — this is release packaging, not a new bug fix.
The underlying fix already merged via #1121.
### Merge guidance
**Do not merge into `master` unless you've decided that's appropriate.**
The likely intent is:
1. Review this branch / PR for correctness of the cherry-pick +
CHANGELOG.
2. Tag `v3.7.2` on the head of `release/v3.7.2` (the version-bump commit
is real code, not `[skip ci]` — safe to tag per AGENTS.md rule 33).
3. Run the release workflow off the tag.
4. Optionally close this PR without merging, since master's history will
diverge from the hotfix branch by design.
If you DO want master to also carry the CHANGELOG entry, that can be a
separate cherry-pick onto master after this lands — but the fix itself
(#1121) is already on master.
### Verification
- `git diff v3.7.1..HEAD --stat` is 3 files / 168 insertions / 4
deletions — minimal surface area.
- TDD test from #1121 squash is included (`cmd/ingestor/db_test.go`
additions).
- No additional commits pulled from master.

## Summary
Resolves the **5 layout bugs** documented in
`specs/packets-layout-audit.md` from the issue investigation. All fixes
shipped in one PR per the audit's recommended fix order.
Fixes#1128
### Bug 4 (P0, 1 line) — `--surface` undefined
`var(--surface)` was referenced in **8** rules across `style.css`
(`.fux-saved-menu`, `.fux-popover`, `.path-popover`, `.fux-ac-dropdown`,
`.fux-ctx-menu`, `.path-overflow-pill:hover`,
`.fux-saved-trigger:hover`, `.fux-popover-header sticky`) but the
variable was **never defined** — every caller resolved to `transparent`
and row content bled through. Aliased `--surface: var(--surface-1);` in
the `:root`, `@media (prefers-color-scheme: dark)`, and
`[data-theme="dark"]` blocks.
### Z-index scale (foundational)
Added documented custom properties at the top of `style.css`:
```css
--z-base: 0;
--z-dropdown: 100;
--z-popover: 300;
--z-modal-backdrop: 9000;
--z-modal: 9100;
--z-tooltip: 9200;
```
New code uses these tokens. Existing working values left in place to
avoid behavioural risk.
### Bug 1 — path chip re-measure
`_finalizePathOverflow` runs **before** `hop-resolver` mutates chip text
from hex prefix → longer node name. Chips that fit on first measurement
overflow once names resolve, but the `+N` pill never gets appended.
Cleared the per-host `overflowChecked` guard and re-ran finalize on a
120 ms debounced timer, so post-resolution overflow is detected.
### Bug 2 — `+N` popover position + z-index
`.path-popover` was `z-index: 10500` (above the modal stack) and only
ever positioned **below** the pill — when near the bottom of the
viewport it hung over adjacent rows. Lowered to `var(--z-popover)`
(300), capped `max-height` from `60vh` → `240px`, and added flip-above
logic when there isn't room below.
### Bug 3 — filter-bar gap + multi-select truncation
`.filter-bar { row-gap: 6px }` was too tight for the 34px controls;
bumped to `12px`. `.multi-select-trigger` had no `max-width`, so a
selection like `"TRACE,MULTIPART,GRP_TXT"` ballooned the row and
overlapped toolbar buttons. Capped `max-width: 180px` with
`text-overflow: ellipsis` and surfaced the full selection in the
trigger's `title` attribute (so the value remains discoverable).
### Bug 5 — already addressed in #1124
Verified `.filter-group` structure prevents mid-cluster wrap; no further
change needed here.

## Why
Diagnostic on #1129 shows PR #1117 (group commit M1 for #1115) is
fundamentally broken: it starves the MQTT goroutine via `gcMu` lock
contention, causing pingresp disconnects and lost packets at modest
ingest rates.
## Three structural defects
1. **Lock held across `sql.Stmt.Exec`** — every concurrent
`InsertTransmission` blocks for the full SQLite write latency, not just
the brief queue mutation.
2. **Lock held across `tx.Commit`** — the WAL fsync runs *under* `gcMu`,
so any backlog blocks all ingest writers AND the flusher ticker,
snowballing under load.
3. **Single-conn DB** (`MaxOpenConns=1`) — the flusher and the ingest
path serialise on one connection, turning the lock into a global ingest
stall.
Net effect: at modest packet rates the MQTT client loop misses its own
pingresp deadline, the broker drops the connection, and packets received
during the stall are lost.
## What this PR removes
- `Store.SetGroupCommit`, `Store.FlushGroupTx`, `Store.flushLocked`,
`Store.GroupCommitMs`
- `gcMu`, `activeTx`, `pendingRows`, `groupCommitMs`,
`groupCommitMaxRows` Store fields
- `groupCommitMs` / `groupCommitMaxRows` config fields and
`GroupCommitMsOrDefault` / `GroupCommitMaxRowsOrDefault` accessors
- The flusher goroutine in `cmd/ingestor/main.go`
- `cmd/ingestor/group_commit_test.go`
- The `if s.activeTx != nil { … pendingRows … }` branch in
`InsertTransmission` — reverts to plain prepared-stmt usage
## What this PR keeps (merged after #1117)
- #1119 `BackfillPathJSON` `path_json='[]'` fix
- #1120/#1123 perf metrics endpoints — `WALCommits` counter retained
- `GroupCommitFlushes` JSON field on `/api/perf/write-sources` is kept
as always-0 for API stability (server `perf_io.go` references it as a
string field name; no client breakage)
- `DBStats.GroupCommitFlushes` atomic field is removed from the Go
struct
## Tests
`cd cmd/ingestor && go test ./... -run "Test"` → `ok` (47.8s).
`cd cmd/server && go build ./...` → clean.
## #1115 stays open
The group-commit *idea* is sound — batching observation INSERTs would
meaningfully reduce WAL fsync rate. But it needs a redesign that does
**not** hold a mutex across blocking SQLite calls. Suggested directions
for a future M1:
- Channel-fed writer goroutine (single owner of the tx, ingest path is
non-blocking enqueue)
- Per-batch DB handle so the flusher doesn't serialise the ingest
connection
- Bounded queue with backpressure rather than a shared lock
Refs #1117#1129
## Summary
Fixes#1122 — Packets page filter UX repairs.
## Bugs addressed
1. **Filter syntax help no longer floats over the packet table.** It now
opens inside a real `.modal-overlay` backdrop and is centered via the
existing `.modal` flex pattern (same pattern as BYOP).
2. **Duplicate "Filter syntax" header removed.** The inner `<h3>` was
redundant with the popover header `<strong>`. Help body now contains
exactly one occurrence.
3. **Path column chips no longer spill into adjacent rows.**
`.path-hops` now uses `flex-wrap: nowrap` + `max-height: 22px` +
`overflow: hidden`; individual `.hop-named` chips cap at `max-width:
120px` with ellipsis. `td.col-path` itself caps at `max-height: 28px` so
a long hop chain can never push the row past 28px regardless of hop
count.
4. **Toolbar grouping documented.** Added a fenced section comment in
`style.css` enumerating the four logical clusters (quick filters /
toggles / time window / sort & view), bumped `.filter-bar` gap from
6→8px and added `row-gap: 6px` so wrapped controls stay readable at
narrow widths.
## Test
TDD red→green. New Playwright E2E
`test-issue-1122-packets-filter-ux-e2e.js` asserts:
- Help panel rect does not overlap any visible `#pktBody` row, and a
`.modal-overlay` backdrop is present.
- Help panel contains exactly 1 `Filter syntax` occurrence (not 2).
- Every rendered `.col-path` cell stays under 60px height.
Wired into `.github/workflows/deploy.yml` Playwright fail-fast step. Red
commit: `bd58634` (test only). Green commit: `c580254` (impl).
## Files
- `public/filter-ux.js` — `_showHelp` wraps the popover in
`.modal-overlay`; `_buildHelpHtml` drops the duplicate `<h3>Filter
syntax</h3>`.
- `public/style.css` — `.modal-overlay > .fux-popover` reset,
`.path-hops` clipping, `td.col-path` height cap, `.filter-bar` section
comment.
- `test-issue-1122-packets-filter-ux-e2e.js` — new Playwright E2E.
- `.github/workflows/deploy.yml` — runs the new E2E.

## Summary
Implements per-component disk I/O + write source metrics on the Perf
page so operators can self-diagnose write-volume anomalies (cf. the
BackfillPathJSON loop debugged in #1119) without SSHing in to run
iotop/fatrace.
Partial fix for #1120
## What's done (4/6 ACs)
- ✅ `/api/perf/io` — server-process `/proc/self/io` delta rates
(read/write bytes per sec, syscalls)
- ✅ `/api/perf/sqlite` — WAL size, page count, page size, cache hit rate
- ✅ `/api/perf/write-sources` — per-component counters from ingestor
(tx/obs/upserts/backfill_*)
- ✅ Frontend Perf page — three new sections with anomaly thresholds +
per-second rate columns
## What's NOT done (deferred to follow-up)
- ❌ `cancelledWriteBytesPerSec` field — issue #1120 lists this under
server-process I/O ("writes the kernel discarded — interesting signal");
not exposed in this PR
- ❌ Ingestor `/proc/<pid>/io` — issue #1120 says "Both ingestor and
server"; only server-process I/O lands here. Adding ingestor I/O
requires either a unix socket back to the server, or surfacing the
ingestor pid through the stats file. Doable without changing the
existing API shape.
- ❌ Adaptive baselining — anomaly thresholds remain static (10×, 100 MB,
90%); steady-state baselining can come once we have enough deployed
Perf-page telemetry
Per AGENTS.md rule 34, this PR uses "Partial fix for #1120" rather than
"Fixes #1120" so the issue stays open until the remaining ACs land.
## Backend
**Server (`cmd/server/perf_io.go`)**
- `GET /api/perf/io` — reads `/proc/self/io` and returns delta-rate
`{readBytesPerSec, writeBytesPerSec, syscallsRead, syscallsWrite}` since
last call (in-memory tracker, no allocation per sample).
- `GET /api/perf/sqlite` — returns `{walSize, walSizeMB, pageCount,
pageSize, cacheSize, cacheHitRate}`. `cacheHitRate` is proxied from the
in-process row cache (closest available signal under the modernc sqlite
driver).
- `GET /api/perf/write-sources` — reads the ingestor's stats JSON file
and returns a flat `{sources: {...}, sampleAt}` payload.
**Ingestor (`cmd/ingestor/`)**
- `DBStats` gains `WALCommits atomic.Int64` (incremented on every
successful `tx.Commit()` and on every auto-commit `InsertTransmission`
write) and `BackfillUpdates sync.Map` keyed by backfill name with
`IncBackfill(name)` / `SnapshotBackfills()` helpers.
- `BackfillPathJSONAsync` now increments `BackfillUpdates["path_json"]`
per row write — the BackfillPathJSON-style infinite loop becomes
immediately visible at `backfill_path_json` in the Write Sources table.
- New `StartStatsFileWriter` publishes a JSON snapshot to
`/tmp/corescope-ingestor-stats.json` (override via
`CORESCOPE_INGESTOR_STATS`) every second using atomic tmp+rename. The
tmp file is opened with `O_CREATE|O_WRONLY|O_TRUNC|O_NOFOLLOW` mode
`0o600` so a pre-planted symlink in a world-writable `/tmp` cannot
redirect the write to an arbitrary file.
## Frontend (`public/perf.js`)
Three new sections on the Perf page, all auto-refreshed via the existing
5s interval:
- **Disk I/O (server process)** — read/write rates (formatted
B/KB/MB-per-sec) + syscall counts. Write rate >10 MB/s flags ⚠️.
- **Write Sources** — sorted table of per-component counters with a
per-second rate column derived from snapshot deltas. Backfill rows show
⚠️ only when `tx_inserted >= 100` (meaningful baseline) AND the
backfill's per-second rate exceeds 10× the live tx rate. Avoids the
startup-spurious-alarm where cumulative-vs-cumulative was a tautology.
- **SQLite (WAL + Cache Hit)** — WAL size (⚠️ when >100 MB), page count,
page size, cache hit rate (⚠️ when <90%).
## Tests
- **Backend** (`cmd/server/perf_io_test.go`) —
`TestPerfIOEndpoint_ReturnsValidJSON`,
`TestPerfSqliteEndpoint_ReturnsValidJSON`,
`TestPerfWriteSourcesEndpoint_ReturnsSources` exercise the three new
endpoints. Skips the `/proc/self/io` non-zero-rate assertion when
`/proc` is unavailable.
- **Frontend** (`test-perf-disk-io-1120.js`) — vm-sandbox runs `perf.js`
with stubbed `fetch`, asserts the three new sections render with their
headings + values.
E2E assertion added: test-perf-disk-io-1120.js:91
## TDD
1. Red commit (`21abd22`) — added the three handlers as no-op stubs
returning empty values; tests fail on assertion mismatches (non-zero
rate, `pageSize > 0`, headings present).
2. Green commit (`d8da54c`) — fills in the real `/proc/self/io` parser,
PRAGMA queries, ingestor stats writer, and Perf page rendering.

## Summary
`BackfillPathJSONAsync` re-selected observations whose `path_json` was
already `'[]'`, rewrote them to `'[]'`, and looped forever. The
`len(batch) == 0` exit condition was never reached, the migration marker
was never recorded, and the ingestor sustained 2–3 MB/s WAL writes at
idle (76% of CPU in `sqlite.Exec` per pprof).
## Fix
Drop `'[]'` from the WHERE clause:
```diff
WHERE o.raw_hex IS NOT NULL AND o.raw_hex != ''
- AND (o.path_json IS NULL OR o.path_json = '' OR o.path_json = '[]')
+ AND (o.path_json IS NULL OR o.path_json = '')
```
`'[]'` is the "already attempted, no hops" sentinel (still written at
line 994 of `cmd/ingestor/db.go` when `DecodePathFromRawHex` returns no
hops). Excluding it from the WHERE lets the loop terminate after one
full pass and the migration marker `backfill_path_json_from_raw_hex_v1`
to be recorded.
## TDD
- **Red commit** (`19f8004`):
`TestBackfillPathJSONAsync_BracketRowsTerminate` — seeds 100
observations with `path_json='[]'` and a `raw_hex` that decodes to zero
hops, asserts the migration marker is written within 5s. Fails on master
with *"backfill never recorded migration marker within 5s — infinite
loop on path_json='[]' rows"*.
- **Green commit** (`7019100`): WHERE-clause fix + updates
`TestBackfillPathJsonFromRawHex` row 1 expectation (the pre-seeded
`'[]'` row is now correctly skipped instead of being re-decoded).
## Test results
```
ok github.com/corescope/ingestor 49.656s
```
## Acceptance criteria from #1119
- [x] Backfill terminates within 1 polling cycle of having no progress
to make
- [x] Migration marker `backfill_path_json_from_raw_hex_v1` written
after termination
- [x] On restart, backfill recognizes migration done and exits
immediately (existing behavior — the migration check at the top of
`BackfillPathJSONAsync` was always correct; the bug was that the marker
never got written)
- [x] Test: seed DB with N observations all having `path_json = '[]'` →
backfill runs once → no UPDATEs issued, migration marker written
- [ ] Disk write rate on idle staging drops from 2–3 MB/s to <100 KB/s —
to be verified by the user post-deploy
Fixes#1119.
