+// is an ordinary phone account again. It is a stamp rather than a flag so that a

+// card that rewrites the guest back to the starter state in place, keeping its

+// is real progress on it.
+//
+// Credits replace LP: a live flagged `arcade` runs through live_end_ex with

+// record exactly as they do on a phone while LP is never touched.

+// note_slide_hold 13, with isHold(e) = e == 3 and isSlide(e) = e >= 11.
+//
+// SIF2 side: `type` only distinguishes an ordinary note (1) from a star/bomb note (3).
+// LiveTimeController.ToMarkerType accepts 1..3 and maps anything else to None; type 2 exists in
+// the enum but appears in ZERO of the 2146 shipped charts, so nothing emits it here.
+//
+// A SLIDE is structural, not a type. MarkerData derives it from the parent/child chain:
+//   IsSliderMarker      chained and the child is on a DIFFERENT line  -> a slide segment
+//   IsSliderLongMarker  chained, child SAME line, parent different    -> a slide ending in a hold
+//   IsDistanceMarker    has both a parent and a child                 -> a middle segment
+// So a hold is a chain that stays in its lane and a slide is a chain that moves across lanes;
+// both are type 1. This is also how the client counts combo (NoteData.CalcMaxCombo: a note whose
+// child shares its line does not count, its tail does).
+//
 // Mapping rules:
 // - line = position - 1 (both are right-to-left)
-// - effect 1 (and 2, the "parallel" marker) -> type 1 (tap)
+// - effect 1 (note_normal) and 2 (note_event) -> type 1 (tap). note_event is an ordinary
+//   note that also fed SIF1's event scoring; it plays identically and SIF2 has no
+//   equivalent, so the distinction is dropped. Simultaneous hits are expressed by sharing
+//   a spawn num, not by the effect.
 // - effect 3 (hold) -> head note (type 1) at timing_sec plus a SYNTHESIZED tail note
 //   (type 1, same line) at timing_sec + effect_value, linked through parent/child ids
-// - effect 4 (star/token) -> type 3
+// - effect 4/5/6/7 (bomb_1/3/5/9, SIF1's star notes) -> type 3, SIF2's bomb note. SIF1
-// - effect 11/12/13 (swing) and anything unknown -> plain type 1 tap for v1.
+//   varies the blast width per effect; SIF2 has one bomb with one damage value, so the
-//   Slider chains are a later feature.
+//   four collapse into type 3 and only the radius is lost. Previously only bomb_1 mapped
-// - notes_attribute / notes_level are dropped (SIF2 has no per-note attribute)
+//   here and the three wider ones arrived as ordinary taps.
+// - effect 11/12/13 (slide) -> CHAINED across lanes, all type 1. Slides sharing a notes_level
+//   form one run: sorted by time and linked parent -> child, so each link crosses lanes and
+//   the client sees a slider. A run ends on effect 13 (slide hold), whose synthesized
+//   same-line tail then makes it IsSliderLongMarker — the slide settling into a hold the
+//   player releases. Verified against a real upload: every notes_level shared by more than
+//   one note held exactly the slide-effect notes, each a monotonic sweep like
+//   pos 9->8->7->6 with effects 11,11,11,13.
+//   A lone slide with no chain partner stays a plain tap: a slider needs a cross-lane child.
+// - effect 0 (random) and anything else unknown -> plain type 1. Every effect the game
+//   actually defines is covered above, so this is only a floor for hand-authored charts.
+// - notes_attribute is dropped (SIF2 has no per-note attribute). notes_level is consumed as
+//   the chain id above and not emitted.
 // - ids are sequential from 1 in time order. num is the spawn group: the dummy
-//   header occupies 100, real groups count up from 101, and notes that hit
+//   header occupies 100 and real groups count up from 101. The client spawns markers one
-//   simultaneously (equal timing_sec, which covers SIF1 effect 2 pairs) share one num.
+//   num-group at a time, and LiveMarkerControl.CreateMarkerUI (list overload) plain-RETURNS
+//   when the group holds more than 2 markers — so a num may be shared by AT MOST two notes,
+//   or the whole group's head markers never render (hold bands are created by the separate,
+//   unguarded CreateLongMarkerBandUI call, which is why 4 simultaneous holds showed trails
+//   with no heads). Simultaneous notes (equal final time, which covers SIF1 effect 2 pairs
+//   AND synthesized hold tails) are therefore sorted by lane and chunked into pairs: each
+//   chunk gets its own num, and every chunk after the first carries the PREVIOUS chunk's num
+//   in force_sync_group_id. That is exactly the official encoding — all 4292 shipped NoteData
+//   assets have num groups of only 1 or 2, and the 15 charts with 3-4 simultaneous notes
+//   (SIFAC ports, e.g. 1132_5_Sn, 1136_5_An) pair the lowest lanes under the first num and
+//   point the later chunk's m_ForceSyncGroupID at it. The client turns that into the extra
+//   connector line (LiveTimeController.CreateMarkerTimeData force-group pass matches
+//   ForceGroupId against the other chunk's GroupId and links the lane-closest pair).
 // - notes[0] is ALWAYS the dummy header (id 0, num 100, type 0) - the client
 //   deserializes it verbatim.
 // - max_combo_count = all real notes EXCEPT hold heads whose tail is on the same
 //   line (the game counts a same-lane hold as one combo for the chain)
 
+// Two notes are SIMULTANEOUS (one spawn cluster) when their times agree to within this.
+// Uploaded timings are decimal literals, so notes an author meant to be simultaneous parse to
+// bit-identical f64 - but a hold's SYNTHESIZED tail is computed (timing + effect_value), and
+// e.g. 1.4 + 0.7 is 2.0999999999999996, which exact equality splits from a note literally at
+// 2.1. That cost the two the shared spawn num, and with it the client's sync connector line
+// (LiveTimeController.CreateMarkerTimeData pairs GroupSyncMarkerData by GroupId). The client
+// itself never compares two note times - simultaneity is entirely decided here by `num`, and
+// it stores time as f32 anyway - so this tolerance only has to sit above f64 accumulation

+// Every name/description the custom-song and custom-card uploads accept is rendered by the game
+// through TextMeshUI -> TMP with rich text ENABLED (the shipped labels carry m_isRichText: 1),
+// and the client does NOT escape it: it hands user text straight to SetText, exactly as it does
+// for other players' account names. So a song called "<size=400%>x", a card whose skill
+// description carries <sprite=...>, or a character named "<font=nonexistent>" mangles or breaks
+// every screen that shows it - for EVERY player, since public songs and published cards are
+// visible to all. This is the in-game equivalent of stored XSS.
+//
+// The fix belongs here rather than at the render seam, because that is where official data draws
+// the line: the shipped masterdata carries NO markup in any name or artist column (1102 of the
+// 1103 tags in the whole EN music table are <br>, all of them inside detailInfo), <br> in the
+// descriptive columns, and <size=NN> only in character nameRichtextGacha - a column whose name

+// Everything below Title in the client assumes a tutorial-complete account: a

+//   POST /api/lottery            the tutorial draw leaves a card in card_list,
+//                                which is what /user/initialize reads as the
+//                                account's "ur" (lottery.rs:342-358, user.rs:383)
+//   POST /api/user/initialize    favourite + guest cards, 3000 gems, the band
+//                                title, the nine base cards, deck slot 1,
+//                                character_list, the first bond mission
+//                                (user.rs:371-453)

+//
+// The one deliberate difference is the gacha: a cabinet draws nothing random.
