The .fig import gave a file one decoded value per byte of its compressed canvas (at least 20M, at
most 128M). Dense legitimate files decode past that, further since every scalar field counts, and
the whole import was refused as "not a valid FigCraft file: .fig file: message: too many values".
The budget is now four values per compressed byte; the floor and both ceilings (128M, 32M on 32-bit
targets) are unchanged, so a small file that unpacks past the floor is still refused and no file
decodes more values than the ceiling allowed before. Generated 21 MB and 15 MB canvases (220,044
and 108,012 layers) and a 49.7 MB one budgeted at the ceiling (530,106 layers) now open whole
without warnings; the 49.7 MB one's test peaks at about 9 GB.
* M8: opening a file contacts no team library server it names until you check it (#1097)
* M8: translate the team library check strings (#1097)
* M8: the Assets panel library test checks what allows a library, without its own fake link (Sonar duplication and coverage)
* M8: cap the people a client keeps track of and the deleted ids a session remembers (#1121)
A hostile host or server could grow a client's presence, seen-peers and who-is-here lists without bound, and a session's deleted-id set only grew. Clients keep at most MAX_PEERS (4,096) others, leaving newcomers out with a warning; max_people is at most that; a session remembers at most 262,144 deleted ids, the lowest forgotten first.
* M8: a max_people above what clients track is lowered with a warning, not refused (#1121)
Refusing it would stop a server whose existing config says more from starting after an upgrade. Config::people() lowers max_people to MAX_PEERS for the core's limits, and the startup warnings name the configured and the used value.
* M8: the live welcome's handling in its own function (Sonar S3776)
* M8: a large selection's overlay and Design panel values are kept for frames where nothing changed (#1571)
The selection's outlines, box, size and slots on the canvas, and the Design panel's instance checks and position values, are kept with the document snapshot (held weakly), the selection and, for the overlay, the view's mapping to the screen and the overlay green, and made again when any changes. Dragging 648 selected layers: overlays 1.99 to 0.86 ms a frame, Design panel 2.54 to 1.40 ms.
* M8: split the position fields into one function per row (Sonar S3776)
The per-address download bucket never held more than its 16 MiB burst, so a larger library or plugin was refused for good. Bucket::take_spread serves one from a full bucket and leaves the debt to refill at the rate before the next download; the rate over time still holds.
The REST import's layer walk (also the .fig import's second stage) took about 4 KB of stack a level, a megabyte at the 256-level cap, and overflowed a 1 MB thread. It now runs on a work list in the same order, fitting groups once their children are in. The .fig mapping stays recursive at about 1.8 KB a level (455 KB at the cap). Both 256-deep imports now run on a 1 MB stack; the cap stays 256 everywhere.
