From 51614e46878967951b16868f30dd7d910940178c Mon Sep 17 00:00:00 2001 From: dengcchi Date: Sat, 30 May 2026 03:28:44 -0700 Subject: [PATCH 01/11] Navi 6-agent committee run (2026-05-30): 3 rounds + E1 AMD MVP experiment 6 engines (Claude 4.8/4.7/4.6, Codex 5.5, Muse Park/Avocado, Gemini 3.5) on devgpu014. 3 hostile vote rounds over forkedkv/edmm/afar artifacts. No 6/6 GREEN reached (correct). T2 (mid-prompt invalidation) strongest at 5G/1R. E1 cross-vendor experiment on AMD MI350X VINDICATED the lone holdout: forkedkv's CUDA ~520K mapping ceiling does NOT reproduce on ROCm (>=6.4M mappings, zero failure) -> T1 demoted to NVIDIA-scoped. Experiment beat consensus.

ForkedKV M1 shows fork is 1.3x faster than full clone; M3 shows near-zero attention overhead (-0.1% to +1.1%) on forked branches; M2b shows 95% fewer bytes written when branches don't diverge much, meaning discarding wrong speculations costs almost nothing in HBM. +- Closest prior work + the delta: Speculative decoding (Leviathan et al. 2023, Stern et al. 2018) speculates on the LLM's OWN next tokens using a draft model. This speculates on EXTERNAL tool-return values — a qualitatively different prediction target. EDMM's pointer-swap recovers AFTER the penalty; this hides latency DURING the tool call. Complementary, not overlapping. +- Closest OSS competitor + why it doesn't kill this: LangGraph/CrewAI have tool-call parallelism but no speculative prefill. SGLang has speculative scheduling for batched requests, not for branching within a single agent trajectory. +- Fatal flaw (the strongest reason a reviewer kills it): Tool returns are often unpredictable (arbitrary API responses, web scraping results). If prediction accuracy is <30%, the speculative compute is wasted and the mapping-table budget (Thesis 1's 520K ceiling) is consumed by doomed branches. This only works for structured, schema-known tool returns (SQL queries, typed API endpoints). +- Anti-FlashInfer test: YES — this is latency hiding during I/O wait, entirely orthogonal to attention kernel speed. Even infinitely fast FlashInfer doesn't eliminate network round-trip time. +- No-code test: The framing that tool-call latency is a speculative-prefill opportunity (distinct from speculative decoding) is a reusable systems insight applicable to any agent serving framework. +- Highest-EV experiment: On 20 SWE-bench tasks with ≥3 tool calls each, measure end-to-end latency with (a) baseline vLLM (recompute), (b) EDMM pointer-swap only, (c) EDMM + 3-way speculative prefill using tool-return templates.

This is for ONE break point. With N tool calls, the penalty compounds depending on ordering: calls that share longer prefixes with their predecessors cause fewer breaks. ForkedKV's M5 provides 24 real SWE-bench-Verified agent traces with multiple tool calls as evaluation data. +- Closest prior work + the delta: EDMM solves RECOVERY (pointer-swap after breakage). RadixAttention/SGLang provides a prefix tree but no tool-call SCHEDULING. Database query scheduling optimizes I/O locality; this optimizes prefix-cache hash-chain locality — analogous problem, different cost model (hash-chain break = full recompute, not just cache miss). +- Closest OSS competitor + why it doesn't kill this: SGLang's RadixAttention maximizes prefix sharing for INDEPENDENT requests but doesn't reorder tool calls WITHIN a single agent's trajectory. vLLM's prefix caching is passive (no scheduling). This is complementary to both. +- Fatal flaw (the strongest reason a reviewer kills it): Real agent traces may have tight data dependencies between tool calls (output of tool A is input to tool B), leaving little reordering freedom. If ≤10% of tool calls are reorderable, the optimization is trivial. Must demonstrate sufficient slack exists in real workloads. +- Anti-FlashInfer test: YES — hash-chain breakage causes full KV recomputation regardless of how fast the attention kernel is. Faster FlashInfer makes the recomputation cheaper in absolute terms but the RELATIVE penalty (8.21x) is kernel-speed-independent. +- No-code test: The formalization — that agent tool-call ordering is a scheduling problem with prefix-cache locality as the cost function — is a reusable workload model. The taxonomy of break patterns (append-break, insert-break, replace-break) and their cost ratios would inform any future prefix-cache design. +- Highest-EV experiment: Analyze 100 real agent trajectories (SWE-bench + WebArena + ToolBench), measure reordering freedom (% of tool calls with no data dependency on immediate predecessor), then compare TTFT under (a) original order, (b) dependency-respecting reorder, (c) EDMM pointer-swap, (d) reorder + EDMM. Success criterion: (b) alone recovers ≥40% of the gap between (a) and (c); (d) is within 5% of optimal. +- Realistic venue: MLSys | EuroSys/ATC +- Your self-vote: YELLOW — the formalization is clean and the insight (avoidance vs. recovery) is crisp, but the entire thesis lives or dies on how much reordering freedom real agent workloads actually have.

From c9199f5f8617f313a158325a2285d6f6d2bde356 Mon Sep 17 00:00:00 2001 From: dengcchi Date: Sat, 30 May 2026 06:00:24 -0700 Subject: [PATCH 05/11] Rounds 6-7 + E4/E4b/E4c: committee caught a real bug, thesis corrected E4 (single-layer) showed exact repair -> Muse Park FLIPPED GREEN. But claude48+codex caught that E4 only proved layer-0 equality. E4b (multi-layer) CONFIRMED: interior edits corrupt suffix K/V at L>0 (max|dK| up to 4.0); terminal edits stay 0.0 at all layers. E4's interior claim was invalid. T2 rescoped to terminal/append. E4c validated it: argmax-exact at full depth, 5.4-81.6x vs full recompute. R7 re-vote 4G/1Y/1R. New shared objection (claude48+Muse Park): terminal repair == standard prefix-KV incremental prefill that RadixAttention already does (our own E3 measured E_append at 0.90-0.96x = free). Honest consequence: T2's primitive half collapses to existing RadixAttention behavior; the WORKLOAD-MODEL half (E2/E3) is the defensible novel contribution. The hostile committee worked: it caught a correctness bug AND a novelty-vs-prior-art collapse that voting consensus alone would have rubber-stamped. --- bench_e4b_multilayer.py | 90 ++++++++++++++ bench_e4c_terminal.py | 116 ++++++++++++++++++ committee_navi_run_20260530/AGENT_VOTES.md | 33 +++++ committee_navi_run_20260530/REVOTE_T2_R7.md | 41 +++++++ .../experiments/E4_repair/E4b_RESULT.md | 37 ++++++ .../experiments/E4_repair/E4c_RESULT.md | 36 ++++++ .../experiments/E4_repair/RESULT.md | 44 +++++++ .../experiments/E4_repair/bench_e4_repair.py | 97 +++++++++++++++ .../experiments/E4_repair/raw_e4_sweep.log | 14 +++ .../E4_repair/raw_e4b_multilayer.log | 22 ++++ .../E4_repair/raw_e4c_terminal.log | 19 +++ .../votes6/_progress.log | 12 ++ .../votes6/claude46.vote.md | 1 + .../votes6/claude47.vote.md | 1 + .../votes6/claude48.vote.md | 1 + .../votes6/codex.vote.md | 1 + .../votes6/gemini.vote.md | 1 + .../votes6/metacode.vote.md | 3 + .../votes7/_progress.log | 12 ++ .../votes7/claude46.vote.md | 1 + .../votes7/claude47.vote.md | 1 + .../votes7/claude48.vote.md | 1 + .../votes7/codex.vote.md | 1 + .../votes7/gemini.vote.md | 1 + .../votes7/metacode.vote.md | 3 + 25 files changed, 589 insertions(+) create mode 100644 bench_e4b_multilayer.py create mode 100644 bench_e4c_terminal.py create mode 100644 committee_navi_run_20260530/REVOTE_T2_R7.md create mode 100644 committee_navi_run_20260530/experiments/E4_repair/E4b_RESULT.md create mode 100644 committee_navi_run_20260530/experiments/E4_repair/E4c_RESULT.md create mode 100644 committee_navi_run_20260530/experiments/E4_repair/RESULT.md create mode 100644 committee_navi_run_20260530/experiments/E4_repair/bench_e4_repair.py create mode 100644 committee_navi_run_20260530/experiments/E4_repair/raw_e4_sweep.log create mode 100644 committee_navi_run_20260530/experiments/E4_repair/raw_e4b_multilayer.log create mode 100644 committee_navi_run_20260530/experiments/E4_repair/raw_e4c_terminal.log create mode 100644 committee_navi_run_20260530/votes6/_progress.log create mode 100644 committee_navi_run_20260530/votes6/claude46.vote.md create mode 100644 committee_navi_run_20260530/votes6/claude47.vote.md create mode 100644 committee_navi_run_20260530/votes6/claude48.vote.md create mode 100644 committee_navi_run_20260530/votes6/codex.vote.md create mode 100644 committee_navi_run_20260530/votes6/gemini.vote.md create mode 100644 committee_navi_run_20260530/votes6/metacode.vote.md create mode 100644 committee_navi_run_20260530/votes7/_progress.log create mode 100644 committee_navi_run_20260530/votes7/claude46.vote.md create mode 100644 committee_navi_run_20260530/votes7/claude47.vote.md create mode 100644 committee_navi_run_20260530/votes7/claude48.vote.md create mode 100644 committee_navi_run_20260530/votes7/codex.vote.md create mode 100644 committee_navi_run_20260530/votes7/gemini.vote.md create mode 100644 committee_navi_run_20260530/votes7/metacode.vote.md diff --git a/bench_e4b_multilayer.py b/bench_e4b_multilayer.py new file mode 100644 index 0000000..6cb353c --- /dev/null +++ b/bench_e4b_multilayer.py @@ -0,0 +1,90 @@ +""" +E4b — Does an INTERIOR fixed-width edit corrupt suffix K/V at layers >0?

Explicit non-claims on prevalence/impact/emergence. R11: 6/6 GREEN unanimous. Discipline note: methodology audit caught that a too-clean 100%-append first pass missed compaction/system-reminder events; corrected before reporting. The thesis is GREEN because it claims exactly and only what 5 experiments measured.

E8 measured a clean decomposition (pre-RoPE KV bit-identical at L0; context-mix divergence growing to L27). Committee R13: 0G/4Y/1R/1K. Two agents specified the GREEN-gate experiment; E9 ran it: only 1/28 layers reusable -> 0.054% prefill-FLOP saving ceiling at 1.5% real incidence (<< 2% KILL bar). T4 killed honestly.
