Adds Go raw string literals per Go spec § String literals:
backtick-delimited, no escape processing, may span multiple
lines, '\r' chars discarded from the value.
gl-read-raw-string! mirrors gl-read-string! but skips escape
handling and the \r filter. scan! routes the leading backtick
to it; emits "string" type (same as interpreted strings — no
need to distinguish at parse/type time).

Adds Go float and imaginary literal forms per Go spec § Floating-point
literals and § Imaginary literals:
3.14 .5 1. 1e10 1.5e-3 2.0e+2 1E5 (floats)
2i 3.14i 1e2i (imag)
gl-read-number! returns one of "int" / "float" / "imag"; gl-finish-number!
factors out the post-mantissa exponent + 'i' suffix logic so the int /
float / leading-dot-float paths all share it. scan! adds a .<digit>
branch ahead of the operator matcher so '.5' tokenises as float.
ASI trigger list extended to include float + imag (Go spec § Semicolons:
all literal types trigger).
Greedy-grammar pin (a single test '1.method' lexes as float ident),
since the Go spec says the '.' after a digit always belongs to the
number, never to a following identifier.
Hex floats (0x1.fp0) deferred — not commonly used.
lex 114/114.

Adds prefixed integer forms per Go spec § Integer literals:
0x.. / 0X.. (hex), 0b.. / 0B.. (binary), 0o.. / 0O.. (octal),
legacy 0123 octal also accepted. Underscores allowed between digits
in any run; lexer is permissive (parser/types phase can enforce
strict placement).
Dispatch lives in gl-read-number! against the first 1-2 chars;
hex digit run consumes lex-hex-digit? from lib/guest/lex.sx. Octal
and binary use local gl-oct-digit?/gl-bin-digit? — narrow enough
that promoting them to the kit is premature.
lex 92/92.

First Go-on-SX iteration. Tokenizer consumes lib/guest/lex.sx character-class
predicates. Automatic semicolon insertion per Go spec § Semicolons fires on
newline, EOF, and block comments containing a newline, after
ident/int/string/rune/{break,continue,fallthrough,return}/{++,--,),],}}.
Scoreboard + conformance.sh wired; lex 78/78. Plan Phase 1 sub-items
checked; floats/raw-strings/hex-ints still ⬜.

- go-on-sx.md: rewrite of 2026-04-26 draft to integrate lib/guest framework.
Adds Phase 3 (independent bidirectional type checker — first static-typed
guest), Phase 10 (extraction enabler), chisel discipline, conformance
scoreboard model. Phases 1-2 now consume lib/guest/core lex+pratt+ast.
- lib-guest-scheduler.md: NEW. Extraction plan for the fork/yield/block/
resume scheduler shared by Erlang (addressed processes + mailboxes) and
Go (anonymous channels + goroutines). Two-language rule blocks extraction
until both consumers independently work; rejected-extraction is a valid
outcome.
- lib-guest-static-types-bidirectional.md: NEW. Sister to lib/guest/hm.sx.
Bidirectional checker kit (synth/check judgments, pluggable subtype +
unify) for the languages HM doesn't fit — Go, Rust, TS, Swift, Kotlin,
Scala 3, Hack. First consumer: Go-on-SX. Second TBD; recommendation
TypeScript.
The three plans cross-reference each other. Go-on-SX implements scheduler +
checker independently of the kits; extraction is its own workstream once
two consumers exist.
