- Switch font: JetBrains Mono @ 15px → Unifont 16.0.04 @ 10px. Sparse
atlas with double-width EAW dispatch for CJK. Full BMP profile
(35,501 glyphs) covers Latin/Cyrillic/Greek/Hebrew/Arabic/CJK/Hangul
plus Letterlike, Misc Technical, Block Elements, Geometric Shapes,
Misc Symbols, Dingbats, Enclosed Alphanumerics, all box-drawing.
- Fix cell-height bug (was hardcoded 9; now probed from font metrics
via Math.ceil(maxAscent+maxDescent)). Previously clipped the top
2 rows off every CJK glyph since the original Unifont ship.
- Expand tabs to spaces with 4-column tab stops, EAW-aware. Was the
silent-drop source for 99.6% of dropped chars in production.
- Add dropped_codepoints_top telemetry (top 20 per event, only emitted
when drops > 0) so future coverage gaps surface in events.jsonl.
- Raise minToolResultChars 2000→5000 and minReminderChars 1000→2000
to stop net-losing tokens on small compressions, per ~2,500 tok/img
empirical measurement (N=33 cold-miss events).
- Fix dashboard per-image-cost formula: was pngBytes/375 (~190 tok),
now imageCount * 2500 (the measured empirical rate). Reduces the
inflated "tokens saved" headline to honest numbers.
- Schema-stub fix in compressSchemas path: preserveSchemaShell()
retains type / properties / required / enum / oneOf / anyOf / $ref /
numeric constraints recursively (depth 20), strips only descriptions
and metadata. Prevents 400 errors on first-tool-call requests.
- Capture full gzipped 4xx body + per-event req_body_sha8 for upstream
error diagnosis. Sidecar to ~/.pixelpipe/4xx-bodies/ when over 32 KB
inline cap. Workers-safe via CompressionStream + Web Crypto.
- scripts/restart.sh: pnpm-aware one-command kill+rebuild+start with
graceful SIGTERM→SIGKILL escalation, build-failure abort, port-in-use
precheck, --no-build flag for fast iteration. Shell-tested.
- Bundle 1.58 MB gzipped on Node. 91/91 vitest + 4/4 shell tests.
Node host now appends one JSONL event per request to
~/.pixelpipe/events.jsonl (override with --events-file or PIXELPIPE_LOG).
- Size-based rotation at 100 MB (old file → events.jsonl.1).
- Sync writes — overhead is ~1ms, dwarfed by upstream latency.
- Failures degrade silently: a broken disk disables the tracker but
never breaks a request.
- Flushed and fsync'd on SIGINT/SIGTERM so the last batch isn't lost.
- Opt out via --no-track or PIXELPIPE_TRACK=0.
Worker host uses JsonLogTracker with console.log; Cloudflare ingests
this as Workers Logs, and Logpush can ship it to R2/S3 as JSONL —
same shape Node writes locally, so analysis tooling works on either.
Console log line on both hosts now also includes tokens/cache_read
inline (e.g. 'compressed 4799ch → 2img/12343B tokens=1234+56
cache_read=800') so cache effectiveness is visible at a glance even
without parsing the JSONL.
Unknown-tag canary fires a stderr warning when info.unknownStaticTags
is non-empty — surfaces Claude Code releases that introduce new
dynamic tags before they tank the cache hit rate.
Help text and HANDOFF will be updated in the next commit; for now the
new flag drops the need for --exclude-dynamic-system-prompt-sections.
Tests: +5 (toTrackEvent flattening, JsonLogTracker sink behavior, error
swallowing, minimal-event handling, noop).
