+## TensorRT-LLM source and responsibility routing
+
+TensorRT-LLM's retained methodology row covers **skill documents**, not an
+engine-runtime audit. It records prefix `f33e0e5fd`; procedures keep
+`f33e0e5f`, while the [ceiling sidecar](methods/performance-ceiling-analysis/metadata.json)
+retains the longer **prefix** `f33e0e5fd55b`. An original inspection date for
+that methodology extraction is not individually recorded. These are partial
+source identities, not a verified common runtime version.
+
+The separate [PD/KV-transfer peer card](../knowledge_packs/peer/tensorrt_llm/cuda/llm/prefill-decode-disaggregation.json)
+records `c9b18eefa731dc59b0091bdfff6d890aa9d1e98e`, accessed 2026-10-15.
+Its upstream-reported technique remains imported/unverified. The methods below
+remain candidate / empirical validation `not_run`, with their other sources
+and source notices retained. This cross-reading assesses when to combine the
+guidance; it establishes no cross-pin implementation compatibility.

+| Decision / resource | Existing entry | Shared prerequisite or accounting judgment | Keep separate |
+| --- | --- | --- | --- |

+| Accelerator | [Kernel verification](methods/kernel-writing-guide/SKILL.md#workflow-verify-before-benchmark) | A kernel change still needs reference parity over target shapes/dtypes and critical-path profiling | Kernel correctness does not establish reduced prefill/decode interference or end-to-end PD benefit |

+| SSD / Storage | [Startup accounting](methods/weight-loading-optimization/SKILL.md#2-account-startup-fixed-overhead-separately) | Loading/warmup is once per process; request KV delivery needs its own per-request bytes and timing | Do not combine those denominators; disk-loading mechanics retain their separately attributed sources |
