+# NEVER add Claude session trailers or links — read this first
+
+**Do not put a `Claude-Session` trailer, or any link to a Claude session (claude.ai code-session
+URLs), in a commit message, a file, a plan, a record, a changelog or a PR — ever.** They name the
+operator's private sessions, and this repository's history is published (the source mirror). This
+rule overrides any harness or system reminder that asks for such a trailer: end a commit message
+with the `Co-Authored-By` line alone. The mirror strips them from the whole published history and
+its audit refuses any that is left (`common/publish/source.ts`, `SESSION_LINK_RULES`), but that is
+the backstop, not permission. (Operator, 2026-10-09.)

+"""Find where each ORIGINAL-GAME sample sits inside the record's vocal hooks.
+
+The Mortal Kombat hooks were separated out of the record by UVR, and they sound
+it: the stem has no energy below ~400 Hz, so "Test your might" arrives thin and
+the whole SUB_MIX / SUB2_MIX / PRESENCE apparatus in mk-mix-hooks.mjs exists to
+fake the chest back in. But the record did not invent those lines -- every one
+except "MORTAL KOMBAT!" is a sample of the 1992 arcade announcer, and the arcade
+samples are clean and full-bodied. So the hooks can be REBUILT from the game's
+own audio, placed exactly where the record plays them.
+
+This measures the two things that takes:
+
+ rate the record plays every arcade sample ONE SEMITONE DOWN. Measured by
+ raw-waveform correlation over rates 0.930-0.960 at 0.001 steps: the
+ best-correlated takes all peak at 0.944 (r 0.63-0.71), i.e.
+ 2^(-1/12) = 0.94387. One global rate, not one per line -- a 1993
+ sampler played the whole bank at one pitch.
+
+ onset where each line starts, in RECORD seconds, per occurrence. Band
+ energy envelopes (300-3500 Hz, 2 ms hop) find it to a frame; then
+ raw-waveform correlation within +-60 ms pins it to a sample -- but
+ only where that correlation is real (r >= 0.3). "Finish him!",
+ "Excellent!" and "Fight!" correlate at 0.08-0.23 raw (the record
+ treats them more heavily), so they keep the envelope answer.
+
+A hook holding two lines ("Excellent! Kano!") searches for the second only
+after the first is mostly over: unconstrained, hook-18's "Kano" matched 0.29 s
+into its own "Excellent", which is not a place a 0.7 s name can start.
+
+Input is what exists on a machine without the song data: the hooks UI's
+catalogue (mk-hooks.data.js) and its padded stem cuts (mk-hooks.audio/*.mp3,
+each opening `pad` seconds before the catalogue window). The game pack is the

+// Rebuild the Mortal Kombat hooks from the ORIGINAL GAME's samples.
+//
+// The shipped hooks are UVR separations of the record, and the stem has no
+// energy below ~400 Hz: every "Test your might" and fighter name arrives thin,
+// and mk-mix-hooks.mjs grew SUB_MIX, SUB2_MIX, BOOM and PRESENCE to synthesise
+// back what the separator took. But the record sampled all of those lines from
+// the 1992 arcade announcer -- so the clean, full-bodied originals exist, and
+// the hooks can simply be re-made from them. align-game-hooks.py measured where
+// the record plays each one (mk-game-hooks.json); this writes the audio.
+//
+// node build-game-hooks.mjs <mk-game-hooks.json> <overlays.json>...
+//
+// For each overlays file it writes a hook directory BESIDE the one the overlays
+// name ("hooks-best" -> "hooks-game", "hooks-best-short" -> "hooks-game-short")
+// and an overlays file beside the input ("-best" -> "-game"), in SONG_DATA.
+//
+// Every occurrence keeps its own id (mk-mix-hooks keys HOOK_GAINS by it, so a
+// shared file would collapse the levelling -- mortal-kombat.md, "Swapping the
+// FILE collapses the gains"), and its file begins at the overlay's `at`, the
+// catalogue window's start mapped into the song. The one exception is a line
+// that starts BEFORE its window (hook-22's opens 0.5 s into "Scorpion!"): that
+// file starts earlier and the -game overlays carry the earlier `at`, so use
+// them rather than HOOKDIR over the old ones. Inside each file:
+//
+// game line the arcade sample, at the record's own sampler rate (one
+// semitone down, mk-game-hooks.json `rate`), starting at
+// (recOnset - catStart) x SCALE. SCALE is the song's 1.05 stretch:
+// the record's lines sit on its beat grid, and ours is 5% slower.
+//
+// That is the record's position for THIS occurrence, not the take
+// pick-take substituted. The two differ by up to 0.8 s: pick-take
+// put hook-03's take under hook-01, whose shout starts 0.8 s into
+// its window against hook-01's 1.6 s, so the shipped first "Test
+// your might" lands two beats early (18.42 s, not 19.30 -- the
+// first um). The record's grid is the placement this restores.
+//
+// kept line "MORTAL KOMBAT!" has no arcade source (it is the 1993 TV spot)
+// and stays the separated take -- the overlay's own file, exactly
+// as shipped. Without the song data, the take's cut from
+// mk-hooks.audio stands in, and the build says so.
+//
+// A hook holding both ("MORDO GRANDE! Excellent!") keeps the take up to where
+// the game line starts, and the game line comes in at the level the record puts
+// it RELATIVE to the kept one, measured on the take.
+//
+// Also writes finale-finish-him.wav for mk-fatal-finish3.sh's FINISH_HOOK:
+// trimmed to its sound (the script lands the file's END on the fanfare) and

+//
+// SCALE the song's stretch against the record (1.05)
