wikilink-cascade-from-intentional-deletions-must-fix-same-operation
Deleting files that are heavily linked in the vault (e.g., handoff files with 101+ incoming wikilinks) creates a cascade of broken wikilinks that violates Law 2 (Zero Ambiguity). The fix must occur in the same operation as the deletion — not deferred. Archive-reference substitution pattern: replace broken ~~slug~~ <!-- broken wikilink, target missing --> links with plain-text references to the git commit or canonical spec that supersedes the deleted file.
