Passed session-scoped settings through Edit and Write generated-file checks and fell back to schema defaults when no global singleton exists.
Guarded inline image sizing against an uninitialized global settings proxy and added isolated-session regression coverage.
Fixes#6549
Applied the read-selector misfire check to archive members after loading
the archive entry map and before mutation. Missing empty selector-shaped
members now fail closed, while existing literal members remain writable.
Added regression coverage proving rejected writes leave archives unchanged.
A read-only step that mis-dispatches read as write passes the full read
expression (src/foo.tsx:1-260:raw) as the target. Because a literal colon
filename is legal on POSIX (#4618), write resolved it to filesystem creation
and reported success, leaving a stray zero-byte file the model could not
recover from - the local analogue of the xd:// near-miss guard (#6123).
assertNotReadSelectorMisfire now fails closed when the tail parses as a
read-tool selector, the literal target is missing, and content is empty,
pointing at the equivalent read(...). Non-empty content stays the escape
hatch and existing literal colon filenames remain writable.
Fixes#6387
