Subsystem references and a symptom index: the failure catalogue of docs/agents/03-bringup.md and the per-title material of docs/agents/04-graphics.md (section 1's container list, section 6 and its "Seen in <game>" subsections) move into docs/reference/, one heading per mechanism: rewriter.md, memory.md, threads.md, services.md, movies.md, audio.md, frame-rate.md, nvn-objects.md, rendering.md (with the Vulkan and OpenGL layers), shaders.md and game-state.md, indexed by docs/reference/README.md. Each entry gives the symptom, the cause, the fix (file and function), the games it was found on (linked to their notes in dm/games/<id>/README.md) and any check, caveat or later change; one mechanism met on several games is one entry. docs/agents/symptoms.md lists every entry's symptom (an assertion, a [RED] line, an abort or crash site, a visible result) with a link to it, 350 lines, generated from the Symptom bullets. 03 keeps the loop and reading the log, and its Failure catalogue section now points to the references, the index and where a new finding goes; 04 keeps sections 1-5 and 7 (the container list is shaders.md's Containers by engine), and section 6 says where each kind of finding is. Facts in the old sections about one game only were checked against that game's note, where they already were. Statements the code no longer matches are marked as history beside the current value (movie output slots: MD_NOUT 64, MD_NOUT_AAC 32, MD_NOUT_VIDEO 16; APP_POOL is the profile key app_pool; Engage's layout is 5 / 4.375 GB; inline uniform updates are deferred by default; scaled copies are drawn), and Tears of the Kingdom joins the node-area entry's build list (issue #70). The game notes, docs/agents/README.md, 02 and 05 link to the exact entries, and so do the comments in nvn_mtl.m (nvnTextureCompare) and hle_audio.c (the RemoteIO buffer) and the provisional-profile note in profile_guess.py. 03 goes from 29,600 to 470 words, 04 from 34,400 to 3,500. Checked: every backticked span, module address, issue / PR number and 16-digit hash of AGENTS.md, development.md, dm/games/README.md and docs/agents/01-05 at 6a06877 (4,600 items) still appears in the repository's Markdown (the same five file patterns as before appear as the full names they stood for), every relative link and heading anchor in the repository's Markdown resolves, and the tool tests pass (the four that need capstone or lz4 in the T7 venv)
