Hand-written .fln programs exist, flan convert writes corpus-shaped paren text, and several .fln diagnostics suggest .fln spellings

A function that returns or stores into a global an address or slice of its own frame is refused, a dev free-all poisons any arena's released bytes and ASan sees them released, and @sanitize checks stack use after return

Places are evaluated once, enums have a predicate, CFn values live in structs, and a program's names cannot break the prelude

A dev build refuses (free s) on a slice over a Vec's or a Map's storage, and says a formatted number's text is released by free-temp

(free s) hands a slice (bytes s) or (clone xs) made back to the context allocator or a named one, a dev build traps on the wrong allocator, and a sliced array literal lives for its whole function on x86

map-keys and map-values walk a Map of closures, since (map-next m cur k) walks keys alone and neither needs a zeroed value, and nothing names spike/ any more

The Map header mirror the collector reads is checked against flan_rt.c's, array key pairs cannot share a name, and a program holding only a Map of dyn sets up the collector

A parent's handler reads a name and message made in context/temp, whole and good until the frame ends, and the handler-case landing no longer holds a buffer of its own

An expression at a stop that destroys the program's temp arena leaves context/temp empty rather than restoring the destroyed record

Merge master; an expression evaluated at a stop runs against a scratch temp arena that is wiped after it, and the program's own temp arena is never rolled back

An expression evaluated at a stop rolls the temp allocator back to where it was, so its own text is reclaimed and the stopped frames' text survives

An abandoned evaluation puts the context allocator back, and a fault's break loop runs on a guarded stack of its own so a runaway recursion evaluated there is another break rather than a dead session

The temp allocator grows a block that outgrows its chunk, answers a formatted number with one bump allocation, poisons what a dev wipe releases, and is wiped after each expression run while parked

A handler for a parent reads the condition's own name and message or the condition printed with its values, kept in the handler-case's own frame across the unwind, and a frame re-entered through a signal or a C call names where it is

i64->bytes and f64->bytes allocate from a growing temp allocator that (free-temp) releases once a frame and a dev build's agent poll wipes, so a number drawn every frame no longer leaks

Only a string the checker marks as a literal reaches C uncopied, a slice of dyn is refused at its clone, and the context allocator holds an incarnation so a restored context whose arena was destroyed traps

A condition type may name a parent and a handler for Error catches every built-in error, a signal passes one descriptor carrying its chain, name, sentence and site, and the break loop shows the sentence the runtime wrote

A handler-bind clause runs with only the handlers outside its own form in force, and a stale call in main's running loop stays listed until the callee changes back or the program re-runs
...
The first is CLHS 9.1.4.1: a clause that signalled the condition it handles used to re-enter itself until the stack ran out. The stale list now names a lifted clause by the function it is written in, and BUILT.md's cost line is measured against master.

A Map is a Swiss table, one control byte a slot with key and value side by side
...
Removal marks a deleted slot unless no probe can have passed it, and a rebuild at the same capacity sweeps them. The header, the entry points and the iteration contract are unchanged. A Map has no bounds check, so the entry asking to convert one is closed with nothing to convert.

A function whose signature changed installs, and a caller compiled against the old one stops on StaleCall at the call
...
A dev cell carries its body's signature word beside the body, every call through a cell (and every function value taken from one) compares it with the word the site was compiled for, and the session lists the stale callers by file and line on the reply. Both backends, both installers; release builds have neither the word nor the compare.
