Two bugs:
1. Sentinel used double-underscore delimiters (__DESC:id__) — fragile regex
[^_]+ would break on IDs containing underscores, and Pass-1 output
containing sentinels would leak through Pass 2 unstripped.
2. After Pass 2 substitution, sentinels inside substituted text (from
Pass-1 output of the referenced id) were never cleaned up.
Fix: switch to null-byte delimiters (\x00DESC:id\x00) which cannot appear
in user text, and add a second .replace(SENTINEL_RE, '') pass to strip any
sentinels that survive after substitution (self-refs, nested cycles).
- selectUnit/selectGroup now async; call autoSaveCurrentForm before switching
- Enter in any form field (except textarea) triggers save
- Escape restores form to snapshot (discards unsaved changes)
- discardUnitForm/discardGroupForm helpers for snapshot restore
- Replace native title-based tooltip with custom positioned div
Native title only renders on mousemove; custom div fires on mouseenter
after 500ms delay as intended
- Tooltip styled dark with fade-in; Dan Mode gets yellow-on-black with magenta glow
- Units with descriptions show a small superscript ⓘ on the result label
Pass 1 resolves all field tokens ({id}, {id:label}, {id:plural}, {id:symbol})
and replaces {id:description} tokens with sentinels.
Pass 2 replaces sentinels with Pass 1 output for the referenced id — one level
deep, so mutual references expand once then stop cleanly.
ConverterCard now uses resolveAllDescriptions() for efficiency (one map
build per reactive update instead of per-unit).
- Unit and Group get hidden?: boolean — filtered server-side before render
- Hidden group also suppresses all its units from the converter
- New resolveDescription() utility in src/lib/description.ts
supports {id}, {id:label}, {id:plural}, {id:symbol} placeholders
- ConverterCard pre-resolves descriptions and passes result to ConversionResult
- ConversionResult accepts description prop instead of reading unit.description
- Admin forms: Hidden checkbox added for both units and groups
- drag-handle color overridden to --pico-primary-inverse on selected/drag-over rows
(white in light/dark themes, black on Dan Mode yellow)
- Left panel widened to 340px (was 280px)
- Removed redundant edit pencil icons from unit rows — clicking the row selects it
- Group names truncate with ellipsis instead of wrapping
- Added select-all/none checkbox per group header (with indeterminate state)
- Bulk action bar is now persistent at top of left panel, always visible
- Bulk actions use two-dropdown pattern: Action (Move to group) → Target group
- 'Add unit' text shortened to '+ Add unit', no more wrapping
- Delete-group orphan label clarified: 'Delete group only — keep units as Ungrouped'
- Extract KEBAB_RE, SESSION_COOKIE, SESSION_MAX_AGE_MS, COOKIE_MAX_AGE,
authRequest(), and sessionResponse() to auth.ts — eliminating 4 copies
of the auth() wrapper and 3 copies of KEBAB_RE across admin API routes
- Remove timing side-channel: drop a.length !== b.length early-return
before timingSafeEqual in verifySession (SHA-256 HMAC always 64 chars)
- Fix YOLO localStorage write-before-read race using initialization guard
- Fix admin layout /api/ bypass to return {} instead of {authenticated:true}
- Extract extractError() helper in admin page — removes 4 inline patterns
- Parallel Promise.all in admin loadData() — halves round-trip latency
- Parallel Promise.all in moveCheckedUnits() + surface per-request errors
- Hoist Big(inputValue) above .map() in converter — one alloc per recompute
- O(n) single-pass orderedResults using Map instead of O(n*groups) filters
- Fix expandedGroups.add() mutation — use Set assignment for consistency
