Each turn runs claude -p with stream-json in and out and maps its events onto pi's assistant message stream. A process that stops on tool calls is kept alive and continued when pi sends the results back, instead of replaying the whole transcript. API credentials are removed from the CLI environment so turns always bill to the signed-in subscription.
A localhost-only MCP HTTP server, guarded by a per-turn bearer token, lists pi's tools and holds each call until pi has run it and returned the result.
The hand-packed icns was pixel-clean (verified by unpacking and scanning
every size), but macOS 26 composites legacy .icns icons into the Liquid
Glass system at render time; stacked on Icon Composer's baked PNG-export
lighting, that clips the rim highlights into the near-corner specks and
abrupt highlight ends (owner report 2026-10-13). The fix is the real
layered icon: mac.icon now points at the Icon Composer document
(build/icon.icon, copied from ~/Documents/Affinity/lh-logo) and
electron-builder compiles it via actool into Assets.car — macOS 26+
renders the true Liquid Glass design (dark/tinted variants included).
actool's backwards-compat icns caps at 256px, so scripts/after-pack.cjs
swaps in the existing full-res build/icon.icns before signing: pre-Tahoe
macOS keeps today's quality, Tahoe gets the layered icon.
Windows/Linux get the owner's flat design (rounded squircle with baked
transparency): scripts/make-icons.mjs renders build/icon-flat.svg via
resvg into build/icon.ico (16→256 PNG entries) + build/icon.png (512),
and electron-builder.yml pins win.icon/linux.icon.
desktop:dist injects DEVELOPER_DIR (actool needs Xcode; the machine
selects CommandLineTools by default, CI's setup-xcode takes precedence
via the :- default). The release workflow's mac job selects Xcode 26+
explicitly. Verified locally: mac --dir build (Assets.car + checksummed
full-res fallback + CFBundleIconName/IconFile) and the win-unpacked exe
carries our ico bytes; NSIS/AppImage assembly is CI's (cross-build
tooling can't run on arm64 macOS). Runbook updated. 1610/1610.
Titles become text-sm font-semibold in destructive red — JetBrains Mono
via the UI default, matching the abort-turn/dismiss-question dialogs the
owner named as the ideal look. Node and session names below the title
drop the sized-up text-lg for normal text-sm, still white mono, no
code-block chrome. Settings and Setup keep their serif titles by owner
ruling; abort-turn already renders this way. 1610/1610 both configs;
verified live on the running dev server.
The mount-time jump never fired on real graph-link arrivals: the
transcript scroller's ref is attached by a later sibling, and the queued
rAF was cancelled outright whenever use-stick-to-bottom re-created its
context while the initial scroll settled — every link landed at the
bottom (owner report 2026-10-13).
Rewrite the mount path as a synchronous 64ms retry watcher that keeps
running past its first success (hydration/adoption can replace the
jumped-to node), with a ~20s watchdog for cold-compile SSR streams
(observed 6.8s). jump() now reads the stick-to-bottom context through a
ref so effect identities stay stable, and the unmount cleanup no longer
strips a live flash. Verified live on real data: full load, SPA link
navigation, and in-session hashchange all land the anchor 16px from the
scroller top with the 2s highlight.
Also gives the node card's session/file rows matching horizontal and
vertical padding (px-2 py-1.5).
micromark-extension-math's inline closer is code-span logic — any
size-matched $ run closes, backslash-escaped dollars included — so
"$x = \$5$" closed at the escape, errored in KaTeX, and could cascade
into later text. KaTeX itself renders the escaped dollar fine, and its
own auto-render scanner skips escaped dollars, so the author's intent
is unambiguous.
Fix at the render seam (transformMathDelimiters): inside a balanced
inline span, an escaped dollar becomes the dollar-free
\text{\textdollar} before tokenization, with an escape-aware closer
(odd-backslash dollars never close; even-backslash row-break closers
keep closing). Display spans are untouched (a lone $ can't close $$ —
the escape already survives there), prose escaped dollars, code, and
unbalanced spans pass through, and spans without escaped dollars emit
byte-identical text — corpus-verified over 489 dollar-bearing fields
in 40 real sessions (35 changed, all escaped-dollar spans; the
economics session's dollar-amount math now renders).
The latex-testing session's Test-6 question renders 14 KaTeX spans
with zero errors (was 12 + 2 errors). 1578/1578 tests both configs;
typecheck, lint, build, and Electron-runtime smoke green.
- switch the math authoring/rendering contract from \(...\)/\[...\] to the
standard $...$ inline / $$...$$ display: prompts (20-question-tools,
40-formatting), singleDollarTextMath on the renderer, legacy reader kept,
and escape-debris recovery extended to dollar spans (mirroring micromark
delimiter-run rules)
- exact answer membership now precedes debris cleanup in
coerceCorrectAnswer (calculus incident: an exact sentence-final-period
label was stripped as model debris, then rejected); option keys are
passed at the boundary/grading seams, the dock no longer pre-coerces
- a complete, phase-correct JSON-escaping example rides the probe/quiz
tool descriptions (serialized from one canonical body; quiz leads with
type+nodeId), plus the one-sentence JSON-escaping rule in 40-formatting
- ask option descriptions render markdown/LaTeX in the pending dock;
settled cards keep the details line and option descriptions
retroactively, read from the persisted call arguments (chat passes
part.input to AnsweredCard)
1566/1566 tests on both navigator configs; typecheck, lint, production
build, standalone packaging, and Electron-runtime smoke all green.
Demos execute JS and need a browser; the app's own binary now provides
one: main.cjs boots a hidden window + CDP port under --browser-service
(before the single-instance lock - a helper is deliberately a second
instance of this binary), lifetime tied to the server's stdin (EOF =
quit, no orphans). headless.ts connects over CDP as PRIMARY (owner
ruling 2026-10-10), system Chrome stays the fallback, graceful refusal
when neither. Electron's CDP has no Target.createTarget, so the helper's
pre-created window is THE page, reused and reset per job behind a
serialized queue. PDFs and SVGs never reach a browser anymore (native
since stages 1-2); stale Chrome wording in model-facing tool copy made
engine-neutral. Live-proofed end-to-end from the dev tree (helper seen
by process watch, js-ran 42 probe, no orphan). Gates 1523/1523.
