112 conversions across 19 .sx files using match, let-match, and pipe operators: match (17): type/value dispatch replacing cond/if chains - lib/vm.sx: HO form dispatch (for-each/map/filter/reduce/some/every?) - lib/tree-tools.sx: node-display, node-matches?, rename, count, replace, free-symbols - lib/types.sx: narrow-type, substitute-in-type, infer-type, resolve-type - web/engine.sx: default-trigger, resolve-target, classify-trigger - web/deps.sx: scan-refs-walk, scan-io-refs-walk let-match (89): dict destructuring replacing (get d "key") patterns - shared/page-functions.sx (20), blog/admin.sx (17), pub-api.sx (13) - events/ layouts/page/tickets/entries/forms (27 total) - specs-explorer.sx (7), federation/social.sx (3), lib/ small files (3) -> pipes (6): replacing triple-chained gets in lib/vm.sx - frame-closure → closure-code → code-bytecode chains Also: lib/vm.sx accessor upgrades (get vm "sp" → vm-sp vm throughout) 2650/2650 tests pass, zero regressions.
