Fill component-model coverage gaps surfaced by /report's G4 analysis.
Each ADR documents the component's First action, latency model, and
honest notes on dormant code or implementation asymmetries discovered
during re-evaluation against current code.
- 0038 pcie_ep: thin protocol-overhead model; ComponentBase forwarding
worker as-is; named-node contract for router helpers
- 0039 pe_mmu: component + utility dual role; sub-page region stopgap;
D2.1 flags pipeline path missing mmu.overhead_ns timeout (asymmetric
with non-pipeline; not visible at default tlb_overhead_ns=0)
- 0040 pe_tcm: dual-channel BW serialization (read/write Resource cap=1);
TcmRequest schema owned by TCM; timing-only (no data store)
- 0041 sram: terminal scratchpad model + ResponseMsg on reverse path;
D1.1 flags _worker override as currently dormant (no Transaction
actually targets the SRAM node today)
- 0042 tiling: pure plan-generator module, not a component; corrects
the G4 misclassification; pins GEMM/Math stage sequences and
epilogue scope contract
Also: /report skill G3 refinement — only flag older->newer asymmetric
cross-references; newer->older (e.g., 0034-0037 citing infrastructure
ADRs) are expected one-way and no longer reported.
Bilingual pair verifier (tools/verify_adr_lang_pairs.py) passes.

Extend tl.composite() with an ordered epilogue list. Each op carries
a scope flag - output_tile (default, runs once per (m,n) before
STORE), k_tile (every K-tile right after GEMM), or kernel. Plan
generator slots MATH stages by scope; pe_math reuses pe_dma's
local-loop pattern so chained epilogues (bias->relu) skip the port
hop. op_log captures per-stage params for telemetry. Topology
gains a gemm->math edge (snapshot test updated).
API stays backward-compatible - `epilogue=` is opt-in.
Example:
h = tl.composite(
op="gemm", a=a, b=b, out_ptr=int(out),
epilogue=[
{"op": "dequant", "scale": s_per_k, "scope": "k_tile"},
{"op": "bias", "bias": bias_vec},
{"op": "relu"},
{"op": "scale", "factor": 0.5},
],
)
tl.wait(h)
