 - [ ] remaining zc0 gaps: string literals over 4095 bytes, `embed` of an array type inside a function, `x as T` with more than a single name (`x as int*`), zc0 silently accepting `.u` on a parameter, and integer literals (`010` is 8 in zc0, 10 in the compiler; zc0 saturates on overflow). `docs/history/43-stdlib/notes.md` still says zc0 reserves u/m/d: add a pointer forward rather than rewriting history.
-- [ ] (partly done, see "agent work at the end of the session") verify both compilers against `docs/SPEC.md` with a fresh agent that did not write it: expectations derived from the spec text before running anything, one program per rule under `tests/conformance/<section>/`, a runner `tests/conformance/run.sh`, each failure classified as self-hosted bug, zc0 bug, or spec error, and appendix b confirmed item by item. then add the runner to `tests/test.sh`.
+- [x] verify both compilers against `docs/SPEC.md`: `tests/conformance/<section>/` (sections 1 to 8 plus `9-appendix-b`, 657 programs), runner `tests/conformance/run.sh` (`--zc0`, `--zym`, `--zy`, `-w`), understood failures in `tests/conformance/known.txt` (class a self-hosted bug, b zc0, c spec issue), wired into the interp section of `tests/test.sh`. zy 626 ok, 31 known; zc0 221 ok, 38 known, 398 skipped (outside appendix a). appendix b.2 items 1 to 16 confirmed except b.2.8, which contradicts 5.3.2 and 3.14.2 (the spec documents the address). new class a bugs: `case member():` on a member with fields is rejected (4.7.3); top-level `o3 { }` is rejected (4.10.2, class c). open: `rt.memreport()` reports buddy capacity (`rt.new(2)` is 3 words), whether that is the spec's W; whether top-level `unchecked;` is in the zc0 subset.
 - [ ] fix the implementation bugs listed in `docs/SPEC.md` appendix b, once confirmed: `memdebug scrub;` rejected; enum members can't reference earlier members; a plain function redefinition silently shadows the first; a prototype after the definition hides it; `?:` with one int and one float branch gives garbage; `bool` not normalised; float global initializers rejected; a global initializer naming another global uses its address; `include std;` inside a function body; syntax-error recovery hiding later errors; unterminated `/*` and string literals; `x as int * y`; prototypes needing parameter names; `len(char*)` with typecheck off; duplicate `case` labels; local `const` in constant expressions; constant expressions without precedence (`1+2*3` is 9). fix the prose items the appendix lists too.
 - [ ] (partly done, see "agent work at the end of the session") a cross-reference report: for every global of the compiler, the functions that write it and the ones that only read it. build it from the language server's references (`textDocument/references` on `build/bin/zclsp`, so scoping is exact) and classify each reference as a write when an assignment operator, `++` or `--` follows it. output under `build/xref/`; a committed baseline and a `--check` mode that fails when a new writer of a global appears, so it can run in ci. 
 - [ ] optional, low priority: plain enums and `?:` in zc0 (both are small and produce ordinary code), so parity covers more programs. no structs in zc0 (decided).
