• Components: VS Code/LSP 0.6.0; qpm 0.5-alpha (install/vendor end-to-end, local/static registry + detached signatures; no centralized registry service); docs site + Playground (125 pages / 236 checks); P0 governance + CI static definition (qfmt step); OS SDK 2.0/1.10 MVP notes.
• Verification: test.sh PASS, robustness, async(30/30), std.fs, qfmt (306/0), net POC1+2+3+4+5 + net_aot PASS, bench REGRESSION_PASS, macro, bench, site build

• Known boundaries: u64 bitwise (VM opcode 0x82-0x87; << wrap; >> logical; shift clamp [0,63]; unsigned printing; u64 x non-literal signed TC9 loud; float/bool/nil not open); AOT multi-module POC/POC2/POC3 only (not production 2.0); qfmt v3 safe subset (no ignore file; config discovery upward only); hex float host-strtod dependency; OS SDK 2.0/1.10 MVP prototype (API freeze candidate; net not implemented); Windows AOT not done in 1.4.x/1.5.x; qpm has no centralized registry service; CI workflow static definition (not running on GitHub); LSP 0.12 optional not in tar; NOT PUBLISHED.
