docs(p2): durable G2 status + remaining-placeholder triage (handoff, no re-derive)

Captures what was only in conversation: G1 dissolved (AcceleratorGate
decoupled), G2 partial (Zig FFI 6/6 green), and the exact triage of the
~50 remaining template placeholders into derivable / owner-decision /
crypto-material buckets, with the safe resume path.

-  ~2026-05-20) — needed to inspect its real API for Q1.
-* **G2** `panel-clades/` template instantiated (rsr `{{tokens}}` resolved;

+**Done (2026-05-18, on `feat/panel-clades-pivot`):** `panel-clades/ffi/zig/`
+fully instantiated + migrated to Zig 0.15 — `{{project}}` → `panel_clades`
+(matches `main.zig` exports + `Foreign.idr` `C:panel_clades_*,
+libpanel_clades`); `build.zig` ported (addLibrary/linkage, root_module,
+addInstallFileWithDir, `.link_libc`); `main.zig` opaque→struct,
+callconv(.C)→.c. `zig build test` → **6/6 green**.
+
+**Remaining** = the ~50 non-FFI `{{TOKEN}}` placeholders across ~45 files.
+The template's intended instantiator is its own interactive `just init`
+(see `panel-clades/PLACEHOLDERS.md`). Hand-sed is hazardous: the literal
+`panel-clades` is overloaded across 3 roles (dir name, uppercase ident,
+one-line description) — blind replace = the Axiom corruption class.
