The native frame packet gives you the missing decision frontier, provided you change what the decision is attributed to as well as where it is made.\n\nThe shortest defensible path:\n- **Decision unit:** one owner within one native frame packet, instead of one owner within one Present. Decide once, all-or-nothing, using inputs frozen when the UI publishes the packet.\n- **Attribution:** by command address inside packet-scoped owned ranges, instead of by count markers. The ranges are the builder cursor spans recorded at owned begin/seal on the UI thread. This doesn't care which writer emitted a command, doesn't modify native command bytes, and needs no lifetime tracking per command.\n\nTogether these close all three problems at once:\n- the per-Present cached-owner bypass;\n- unmapped visible content, through a node-level containing-owner veto;\n- incomplete writer and lifetime coverage.\n\nYou don't need to enumerate writers or callbacks to make it safe. What remains is a bounded set of yes/no invariants that one forwarding-only probe can measure. The live identity, generation, pause/replay and 100 ms guards stay exactly as they are, evaluated at the decision point, and the comparison timebase does not change.\n\n## 2. What I confirmed independently from the pinned `.text` (capstone, read-only)\n\n**Packet ring state (`packet+0x28`).** It is written through `DDA550`, which is just `mov [ecx+28],[esp+4]`; the EDX argument is ignored.\n- **BeginFrame `DDBC50`:**\n  - It increments the UI frame counter `ctx+1F8BC`.\n  - Its wait loop at `DDBD30` uses the table at `DDBE50`:\n    - state 0: proceed;\n    - states 1 and 2: reset to 0 at `DDBD4F` and proceed, i.e. an abandoned packet is reclaimed without being executed;\n    - states 3, 4 and 5: wait through `E0BDC0(renderer, packet+2C)`, then re-check.\n  - It then sets `ctx+3094 = ctx+3090` (`DDBD94`), `packet+28 = 1` (`DDBDA5`), `packet+30 = 1`, and records the builder thread id at `ctx+21E9C`.\n  - So the UI cannot rebuild a packet that is queued or executing, and the ring depth bounds how far the UI can run ahead.\n- **EndFrame `DDA8E0`:**\n  - `DDF890` calls `DAF7D0` on every builder in the `packet[0]→+4` chain. That clears cached builder state and sets `+330 = 1`.\n  - It then calls `DB0870(first, each later builder)`.\n  - `DB0870` links builders in place and copies nothing. It writes into the first builder an opcode 5 (8 bytes, `+4` = the later builder's start `+3B8`) followed by an opcode 1. It writes into the later builder an opcode 5 back to the first, then updates `+3B8`/`+331`.\n  - **So addresses written at UI time are the addresses executed.**\n  - Then `ctx+3094 = 0`, `ctx+3090` advances, state goes 2 → 3, and `DDAA0B..DDAA14` loads `EDX = packet+2C`, `ECX = ctx+21D34` and calls `E0E860`. That is the publication point.\n- **Render frame branch `E0D1FB`:**\n  - EDI = `ctx+308C`, state set to 4, then `E0C7C0(packet)`.\n  - `E0C7C0` runs the `+10` callback list, then calls `DB0EA0(packet[0])` from its only caller, `E0CB6B`.\n  - `DB0EA0` appends opcode 6 at the cursor, interprets, then resets the cursor fields (`+14`, `+18`, `+3B8`). Each root build therefore executes once and is recycled.\n  - Next comes the `[renderer+864]` vtable `+44` call (thiscall with EDX = packet, so this is not a direct COM `Present`), then the `+18` list.\n  - Finally `ctx+308C = packet[4]` and state goes 5 → 0. During execution, `ctx+308C` is therefore the packet being executed.\n\n**Recursion is bounded.**\n- The interpreter `DB01A0` has exactly three direct callers: `DB0EE2` (root) and `DD2029`/`DD203A` (the shader/material-list callback).\n- `0x69D740` (node visual dispatch) is called from `0x69B4E9` inside the group traversal, plus two top-level sites. So every descendant node passes through the existing `PresentationOwnerDraw` hook. That makes a node-level veto possible without depending on the text hook.\n\n**Your corrections.** I'm not relying on `DDF960`; it remains unclassified. The opcode 6 that `DB0EA0` appends lands after all owned ranges, so it is allowed explicitly.\n\n**A production gap this exposes.** Production omits only D3D slots 81/82, using loads `DB0416`/`DB0431` (`presentation_ownership.inc:236-255`). UP draws (1c/1d, slots 83/84) emitted under an owned root are always forwarded. The new domain must cover all four terminal opcodes, which AE already instruments.\n\n**Correction to my earlier P5.** Since `Renderer::measure` crops, the plane-budget concern applies only to components that really are full-canvas. Flat lineups is one: `flat_capture75f` asserts a 0,0 full-host plane. Full-screen wipes and backdrops are the others.\n\n## 3. The production decision domain\n\n1. **UI thread, inside each owned traversal** (the existing `0x69D740` wrapper):\n   - Record packet = `ctx+3094`, builder = `packet+8` (`DB3E20` semantics) and cursor = `builder+14` at begin and at seal.\n   - For each dispatched descendant node, record its exclusive cursor delta.\n   - Compare node ids against a static covered-node set per owner, taken from the pinned IFF tree.\n   - If a node outside the covered set emitted bytes, apply the containing-owner veto for this packet and owner.\n2. **Publication**, as a read-only hook at `DDAA0B`, after `DDF890` has sealed and linked all builders and state = 3:\n   - Freeze an immutable plan per packet: our own serial; and for each owner, its traversals (ranges, content snapshot, veto flags, traversal count).\n   - Eligible means: exactly one traversal (or identical ones), ranges within one builder, no veto, content bound, and a plane published.\n3. **Render thread**, at the first terminal draw (any of 1a–1d) whose command address (ECX at the load site) falls in an owned range of `ctx+308C`:\n   - Evaluate the unchanged live guards once: `valid_frame`, identity/epoch/nonce/generation, the 100 ms limits, pause/replay, the claimed dependencies and live content identity.\n   - Fix the decision for that packet and owner. Draw the plane once; omit or forward every later in-range draw consistently.\n   - No decision can change mid-packet, so there is no mixing. The per-Present `decided_`/`chosen` caches go away; `presented()` only drives the trace and the overlay.\n4. **Lifetime:**\n   - Release the plan at state 5 (`E0D33D`).\n   - Drop it on reclaim at `DDBD4F`, or when the serial doesn't match a rebuild.\n   - There are no per-command Pending references, so abandoned packets can't leak slots. Under today's markers they can.\n   - No native bytes are modified, so the Y finding that root bytes aren't immutable (`DDB690` pointer writes into opcode 1d `+14`) no longer matters.\n\n## 4. Minimal static/CPU proofs (no game)\n\n- **S1 — Packet protocol completeness.**\n  - Confirm that `E0E860`/`E0E71F` kind 8 runs published packets in order, exactly once each.\n  - Confirm that the null-job branch `E0D1C2 → E0C7C0(edx=0)` never interprets any packet's root.\n  - Identify what `[renderer+864]` vtable `+44` does (is D3D `Present` inside it?).\n- **S2 — Builder contiguity.**\n  - Is anything other than `DB0870` able to write opcode 5 (for example chunk growth in the writers' ensure-space paths)?\n  - Is `packet+8` thread-affine? The per-thread selection at `E0C83A` (thread id vs `+21D38`/`+21E88`) is a lead.\n  - Does `DAEE80`/`DAF7D0` only append after the cursor, never rewriting earlier bytes?\n  - Do opcodes 5 and 1 really mean jump and label (`DB0272` and `DB0214`)?\n- **S3 — Classify the 49 opcode handlers** by which pixel-producing D3D methods they reach: Draw* 81–84, Clear 43, StretchRect 34, ColorFill 35, UpdateSurface 30, UpdateTexture 31, SetRenderTarget 37. Callback opcodes stay unknown; the probe measures them instead.\n- **S4 — x86 fixture.**\n  - Use the AD2 writer bytes, a `DB0870`-equivalent linker and the Z 49-entry walk.\n  - Assert:\n    - range attribution covers every in-range terminal draw;\n    - all-or-nothing per packet and owner;\n    - a multi-traversal, a split range or an unknown node vetoes;\n    - an abandoned packet releases its plan;\n    - the live guards are evaluated once;\n    - a frame from another run, epoch or generation, or older than 100 ms, is never accepted.\n\n## 5. One bounded forwarding-only probe\n\nThis extends AE2 with capabilities 0 and every command forwarded. It needs gameplay with a notice, a replay, a pause, a break board, wipes and a substitution, ideally the comparison table too, but no natural result. Pass thresholds:\n\n1. **Ring:** every published packet executes once, in order. No rebuild in states 3–5. Reclaims are counted, with their owned traversals listed.\n2. **Coverage:** markers ⊆ owned ranges of the same packet. In-range draws without a marker are counted. Those are writer gaps, and they are owned under range attribution, which is the measurement that ends writer enumeration.\n3. **Execution address = write address,** following the opcode 5 links. Zero copies.\n4. **No foreign-thread writes** into the UI builder during an owned traversal.\n5. **Pixel-producing D3D calls** during an owned-range command that aren't 1a–1d: 0, or listed by opcode. This needs one forwarding hook at the interpreter dispatch, recording the current command and depth. That hook is for the probe only.\n6. **Nesting:** terminal draws at depth > 0 (through `DD2029`/`DD203A`) whose outermost command is in an owned range: 0, or listed.\n7. **Callbacks and handler:** D3D pixel calls from the `+10`/`+18` lists and from handler `+44`, classified.\n8. **Present:** exactly one D3D `Present` per executed packet, with the return chain inside `E0D01F`. Presents without a packet are counted.\n9. **Traversals:** per packet and owner, the traversal count and unknown-node emissions (the real frequency of unmapped content).\n10. **Depth and lead:** the maximum ring depth and the QPC lead.\n\nIf points 2–7 come back non-zero, the fix is bounded to specific opcodes or call sites in the 49-entry table. It doesn't reopen the writer search.\n\n## 6. Alternatives (none is safer or cheaper)\n\n- **Markers plus packet stamps:** still depends on writer coverage, still modifies native bytes, and still leaks slots on reclaim.\n- **Render-target redirection with late composition:** z-order and blend-state risk.\n- **Asset blanking:** breaks the native-fallback policy.\n- **Skipping UI dispatch:** discards callbacks.\n\nPacket ranges also need fewer production hooks than today: the two count-store patches go, and you add the publication read plus four load-site lookups.\n\n## 7. Still open after this\n\n- Sequence semantics through Lifecycle.1.\n- The 11 unrecovered owners.\n- Resize, ultrawide and Reset.\n- Budget for genuinely full-canvas planes.\n- Static covered-node sets for owners other than the scorebug.\n\nFull framework acceptance is unchanged. This only makes the replacement decision complete and safe.",
