docs: point canonical state at Campaign N; record Campaign V closed

CLAUDE.md''s read-first list and the roadmap header now carry Campaign N
(retail reliable-transport port) as the active campaign and Campaign V
as the closed record.

-**Campaign V — OpenGL → Vulkan (active, started 2026-07-27):** the renderer
-migrates to a single Vulkan 1.3 backend on Windows x64 and Linux x64, and the
-OpenGL backend is deleted at the end. The plan is
-[`2026-07-27-vulkan-campaign.md`](2026-07-27-vulkan-campaign.md). Motivation is
-compatibility and efficiency, not rescue: mandatory `GL_ARB_bindless_texture` is
-the exact floor that parked Slice L (Mesa D3D12/llvmpipe lack it), while Vulkan's
-descriptor indexing is core, and per-frame data can be written straight into
-mapped memory instead of copied through `BufferSubData`. Method follows the
-I5→I6→I7 precedent: a Vulkan-shaped RHI implemented **first on GL** so each of the
-twelve renderers ports one at a time under a strict pixel gate on the still-
-shipping backend, then a Vulkan implementation of the same contract, a
-GL-versus-Vulkan differential, a perf gate, cutover, and deletion. Slices V0–V11.
-V0 pinned the contract (`src/AcDream.App/Rendering/Gpu/`, `RecordingGpuDevice`,
-55 contract tests). The ImGui developer stack and UI Studio are **not** ported and
-are deleted at V11; re-homing the dev panels onto the retained UI is a tracked
-follow-up. Targets versus the GL baseline (520 FPS, CPU/GPU p50 1.869/1.096 ms,
-652 MiB working set): CPU p50 ≤ 1.60 ms, GPU p50 ≤ 1.00 ms, working set
-≤ 600 MiB, 0 B/frame managed allocation — with parity on all four as the cutover
-floor. Shipped so far: V0–V2, V4a, V4b, V5, V6a–V6f. V4c/V4d were reverted and
-their GL re-land is closed — an AMD GL driver defect, established by a
-cross-vendor 10/10 on NVIDIA — so their content returns as the Vulkan world path
-(plan §5.5.5–§5.5.6). V6f made every production shader Vulkan-expressible and
-then measured that world path: it is blocked behind a Vulkan composition host,
-three validation-layer defects, and V4t's texture stack, all recorded with
-evidence in plan §5.5.7.
+**Campaign V — OpenGL → Vulkan (CLOSED 2026-07-29):** the renderer now runs a
+single Vulkan 1.3 backend on Windows x64 and Linux x64; the OpenGL backend,
+ImGui developer stack, and UI Studio are deleted. The completed record —
+contract, V0–V11 slices, gates, the AMD GL driver defect saga, and the
+falsification ledger — is [`2026-07-27-vulkan-campaign.md`](2026-07-27-vulkan-campaign.md).
+The user signed the V10 cutover; V11 deleted GL (−27,670 lines) and all
+deferred reruns pass on the GL-free tree.

+**Campaign N — retail reliable network transport (ACTIVE, started
+2026-07-29):** the #260 live-server wedge root-caused to missing packet-loss
+recovery in both directions (no outbound retransmission; inbound ISAAC burned
+in arrival order) — acdream could not survive a single lost UDP packet, and
+loopback gates were structurally blind to it. The campaign ports retail's
+mechanism from the named decomp (SentPacketStore resend with reused ISAAC
+keys, the inbound pre-drawn-key NAK set, the 2.0 s cumulative-ack / 0.6 s NAK
+shared-gate sweep) under the ACE constraint table Coldeve enforces. Slices
+N0–N6 with a permanent loss-injection gate at N5 and a user Coldeve
+endurance session as final acceptance. The plan is
+[`2026-07-29-network-transport-campaign.md`](2026-07-29-network-transport-campaign.md).
