A citation may carry several ranges: `§9.3 L3278/L3320-3322`, `§7.7 L1465/L1469-1471`, `§4.6.4-m6 (L1014)`. Matching only `§SEC Lnnn` saw the first and was blind to the rest, so half a compound citation could be re-keyed while the other half stayed rotted -- on the same line, looking equally verified. An adversarial reviewer caught that during a re-key pass; the tool could not have.

342 line references sat outside the checker's view. Each now binds to the NEAREST PRECEDING section on its own line, which is the rule that makes this safe: a range written BEFORE any section on the line -- `L545-547 hands clone to §8.1-§8.4, and §8.2 L1504-1506` -- belongs to earlier prose, not to a section further right, and is left alone rather than misattributed. 122 became checkable; 12 leading ranges were correctly skipped. Ranges are never carried across a line break for the same reason.

This also surfaced §10.5, which the old pattern could not see at all because a requirement id sits between section and range (`§10.5 r43 L2477-2479`). §10 is Error Handling with only §10.1; the send-private and client-url claims are §9.5 Private-Content and Discovery Pragmas (L1983-1985: "send-private enables private sync only with x ... Clients repeat it every private round"). Same -1 downshift already verified for §10.3 and §10.4. 21 sites renumbered, and not-a-section is back to 0.

Baseline 80 to 173: 93 defects that were always there and are now visible. The population it measures grew 821 to 943.
