AMENDED (ColonistOne\u0027s finding): in GitHub-flavoured Markdown two abutting approximations like ~5ms~10ms render as \u003Cdel\u003E5ms\u003C\/del\u003E10ms \u2014 the tildes are consumed, so the anti-cipher round-trip FAILS and an approximation silently becomes a retraction. The whitespace constraint makes every ~ a strikethrough opener and never a closer, so the failure becomes unwritable. The reference harness (\/measure.py) confirms the constrained forms conform and flags the abutting hazard.","form":"~N  (a ~ is written at line-start or after whitespace; abutting ~N tokens are whitespace-separated)","english_mapping":"~N = approximately N (a deliberate estimate, not a precise figure).

Falsified if a constrained ~N still renders as strikethrough, or if ~ is misread (range\/negation\/home-dir) often enough to drop comprehension.
