All 176 files in the four accumulating directories now use a zero-padded 4-digit counter prefix that reflects creation order (`NNNN-slug.md`). The counter is assigned per directory in strict git-log creation order; ties broken alphabetically by original name. The old `YYYY-MM-DD-` prefix on docs/specs/ and docs/plans/ files is dropped — the date is recoverable from git log and the counter carries the ordering. A file's counter is stable for the life of the file: never reassigned, never reused, never compacted. Deleted files retire their counter; subsequent files do not fill the gap. This is the property that lets cross-references stay literal — refs use the full filename including the counter (`design/contracts/0007-honesty-rule.md`) so they grep cleanly and resolve directly without a glob step. 313 cross-references updated across .md/.rs/.toml/.c/.json files (test pins, include_str! paths, design-INDEX entries, baseline notes, runtime C comments, inter-contract markdown links incl. bare basename and `../models/foo.md` forms). CLAUDE.md gets a new "File-naming convention" section spelling out the rule and rationale. skills/brainstorm/SKILL.md and skills/planner/SKILL.md updated so new spec/plan creation produces counter-prefixed names from the start. The full test suite (cargo test --workspace) passes.

/* Embedding-ABI M3 two-record-param round-trip C host (own + borrow
|
|
* via a compile-time -DBORROW switch). Backfill: M3 shipped fixtures
|
|
* only ever push a *scalar* per-tick sample; this host pushes a
|
|
* single-ctor all-scalar *record* `Tick` as the per-call payload —
|
|
* the actual minimal data-server binding shape. Frozen value layout
|
|
* (design/contracts/0006-frozen-value-layout.md):
|
|
*
|
|
* State (24-byte payload):
|
|
* p - 8 .. p uint64_t refcount header (set to 1 by ailang_rc_alloc)
|
|
* p + 0 int64_t constructor tag (single ctor -> 0)
|
|
* p + 8 IEEE-754 double field 0 = Float acc
|
|
* p + 16 int64_t field 1 = Int n
|
|
* Tick (8-byte payload):
|
|
* p - 8 .. p uint64_t refcount header (set to 1 by ailang_rc_alloc)
|
|
* p + 0 int64_t constructor tag (single ctor -> 0)
|
|
* p + 8 IEEE-754 double field 0 = Float px
|
|
*
|
|
* own : the kernel consumes BOTH `(own (con State))` and
|
|
* `(own (con Tick))` inputs (drop at return); the host must NOT
|
|
* touch/dec either after the call.
|
|
* borrow: `State` is `(own ...)` (kernel-consumed, as own); `Tick` is
|
|
* `(borrow (con Tick))` — the kernel does NOT consume it; the
|
|
* host retains the Tick and dec's it itself each iter.
|
|
* In both modes the return is host-owned and host-freed.
