P2 integrator decisions (feat/disaggregated, 2026-09-07)

ID-1 Ownership grant for the six destructor notifications (closes espryt review v4's major)

Package C (espryt) is GRANTED the four frontend destructor sites that brief C.5 gives to B and D: MG_State/GLState/{TextureState/TextureObject.{h,cpp}, FramebufferState/FramebufferObject.{h,cpp}, SamplerState/SamplerObject.{h,cpp}, VertexArrayState/VertexArrayObject.{h,cpp}} - one include and one out-of-line destructor calling NotifyStateObjectDestroyed each, nothing else. B (tracker) and D (magma) were implemented on p2/contract before this grant and will be rebased across it by the integrator. Reviewers: this is a deliberate, recorded waiver of C.5, not an undeclared deviation.

ID-2 Integration order (replaces brief D.1)

contract -> spans -> espryt -> tracker -> magma -> gates. Reason: espryt now carries the destructor edits in files B and D also touch (different regions); landing espryt first makes B and D the sides that rebase, which the integrator resolves. G5 (the RenderStateImpl sha) and G1 (pull-build symbols) are re-checked after every merge.

ID-3 G1 admitted resize set

The four symbols the contract review measured: RenderState::RenderState(), RenderState::SetCapability, RenderState::IsCapabilityEnabled, and _GLOBAL__sub_I_DirectGLES.cpp (the static initialiser of g_syncedRenderStateParameters, -9 bytes). Anything else must be attributed per symbol.

ID-4 Section-A command errata (apply when running the gates)

• ctest names: grep -E "^[[:space:]]*Test[[:space:]]+#[0-9]+:" | sed -E "s/^ *Test +#[0-9]+: //" | LC_ALL=C sort on both sides (the brief's ^\s+Test # drops every id under 1000).
• retrace_gate.py has no --ssim / --backend; the SSIM threshold is the per-case one in trace_cases.json.
• The verify arming line is MGPipe: verify armed - 63 fields, 69 verbs, fatal=1; retrace case logs carry MGPipe verify: <case> <backend> armed, zero divergences, zero unmigrated reads.

ID-5 Durable locations (the Windows scratchpad was wiped once already)

Brief: ~/w7/notes/p2/BRIEF-P2.md; scouts: ~/w7/notes/p2/scout-*.md; results and reviews: ~/w7/notes/p2/p2-results/; helper scripts: ~/w7/notes/tools/. Write there (through a WSL script or the //wsl.localhost/Arch/home/swung/w7/... UNC path), not only to the scratchpad. Delete your own intermediate logs under ~/w7 when a round ends; keep only the logs your result file cites.
