chore(media): retire the legacy Jellyfin block from dankserver/compose.yaml

The container has had one owner since the Quadlet cutover (dankserver/jellyfin/quadlet/jellyfin.container). The block was a second owner, and wrong on every path: jellyfin/jellyfin:latest instead of the pinned ghcr image, /opt/jellyfin/* data roots that no longer exist, and a read-only /mnt/entropy:/data bind that the metadata view has since replaced. The planner no longer counts jellyfin as a compose service, so editing the inventory cannot restart a media server; tests/deployment_scoping.bats pins that contract for both jellyfin and plex.
refactor(media): mount the view inside /var/lib/media-meta instead of under /mnt

+# convert-qwen38-w5nl64.sh — RUNS ON DANKSERVER. The CPU half of the Qwen3.8-Flash-Next five-bit
+# campaign: convert the vendor BF16 checkpoint into the campaign's arms, each one the whole
+# `w5nl64a8h` rung on BOTH expert projections with the protected experts kept bf16.
+#
+# Nothing here touches a GPU: the container is started without /dev/kfd or /dev/dri, so the
+# converter runs on the host backend and the fleet can keep serving through the whole script.
+# The engine pin is the digest that serves frank-archon, so a winning arm crosses no version
+# boundary between measurement and serving.
+#
+# Three arms, because the campaign's question is which search knob pays for its hours
+# (recipes/qwen4exp-qwen38-w5nl64-bf16trunk.recipe):
+#
+#   cd3     the recipe as written — coordinate descent three sweeps. The control.
+#   cd6     six sweeps: the same search, twice the passes.
+#   ao1     act_order=1 instead of cd: GPTQ sweeps columns in activation-importance order and
+#           stores them permuted. This is a SEPARATE arm, not a fourth sweep — libquant refuses
+#           cd= together with act_order=1 ("cd= sweeps the columns in their stored order, and
+#           act_order=1 stores them permuted; one or the other", libquant/lq_registry.cpp), so
+#           the two knobs cannot be combined into a best-of-both container.
+#
+# The arms are generated from ONE template with `--quant` overrides, not three near-duplicate
+# recipes: --quant rules are inserted BEFORE the recipe file and the first rule whose glob matches
+# a weight decides it (core/format/recipe.cpp: Recipe::match), so an override cleanly replaces the
+# expert line and the other 60 lines cannot drift between arms.
+#
+# Protected experts: apply-protected-cast.sh derives the bf16 set from THIS campaign's grams
+# (--target-count 48, two per layer so each rank's 256-expert half stays even) and splices it into
+# a per-run COPY of the template; the committed recipe keeps its markers and stays reviewable.
+#
+# Gates, in the order they bite — each one is a lesson the swift15 campaign paid for:
+#   inputs        checkpoint (dir + index), recipe, grams, imatrix, tokenizer. A missing grams
+#                 directory converts UNCALIBRATED with one stderr note, which is silently worse
+#                 than failing here.
+#   reference     the 335.3 GiB BF16 reference container must be GONE before the converts start.
+#                 It and the checkpoint together eat the volume; its job (the KLD recording and
+#                 the calibration grams) is finished by then, and both survive on disk without the
+#                 container beside it. The FP8-native anchor is FETCHED after the converts (disk
+#                 sequencing), so nothing here waits on it.
+#   plan          --plan-only runs FIRST, per arm, and prints "about X would be written". The
+#                 number is the bill: free space must cover it plus the 128k-prompt overshoot
+#                 margin, and the finished artifact is checked against it.
+#   outputs       no arm overwrites anything; move the old one to trash.

+# download-qwen38-bf16.sh — RUNS ON DANKSERVER. Fetch and verify the vendor
+# BF16 checkpoint Qwen/Qwen3.8-Flash-Next: the source the five-bit campaign
+# converts, and the source the KLD reference is recorded from.
+#
+# Why the base and not a finetune: the campaign converts to compare against the
+# publisher's own iq4r container, and that container was built from this
+# checkpoint. Base-in, base-out; anything else confounds the gate. (The
+# predecessor campaign ran ukisai/Swift-1.5-Qwen3.8-Flash-Next-BF16, whose key
+# set is identical to this repo's but whose weights are not — none of its
+# calibration grams, KLD reference or protected list carries over.)
+#
+# Why re-fetch instead of reusing: every BF16 copy of this family was destroyed
+# in the 2026-10-15 storage purge — only the 113.6 GiB served .rad survived.
+# 335.3 GiB of safetensors, 131 shards, ungated (the predecessor campaign
+# verified the key set against this repo, so no gate letter is needed).
+#
+# Verification is four gates deep, because the failure this repo actually lived
+# through is a fetch that reported success: `curl -o FILE URL` exits 0 on an
+# HTTP 401/403 and writes the error body as the artifact — three shards of
+# identical tiny size and a cheerful DONE in 20 seconds for 104 GiB.
+#
+#   1. shard census: the file count must equal the expected shard count, so a
+#      partially fetched fragment tree (the .partNofM trap) cannot pass.
+#   2. per-shard completeness, from the shard's OWN safetensors header: the
+#      header declares where the tensor data ends, so every shard's true size is
+#      known offline. A torn tail is named here, by file, instead of surfacing
+#      as a load error five hours later.
+#   3. index coverage: every shard model.safetensors.index.json references
+#      exists and is named.
+#   4. total bytes against the number the Hub declared, then, unless --no-hub,
+#      every file's sha256 against the Hub's LFS record — including the shards
+#      already on disk, so a previous partial download is never trusted.
+#
+# The token never enters a command line (the 2026-09-16 leak law): it is read
+# into HF_TOKEN in the environment, where a local process listing is the only
+# reader. This repo is ungated, so the fetch simply runs without one when no
+# token file exists. scripts/hfget.sh is curl+jq only — no Python, no venv, no
+# hf_transfer — and it drops the pickle/ONNX weight duplicates by itself.

+#!/usr/bin/env python3
+"""grams-to-imatrix.py — the engine's own calibration recording, re-voiced as a
+llama.cpp importance matrix for `rad-convert --imatrix F`. RUNS ON DANKSERVER
+beside the recording. Python 3 stdlib only: numpy must NOT be required, because
+this runs in the plain container next to a 335 GiB checkpoint, not in a venv.
+
+WHY. `rad-convert` takes its per-column activation second moments and its
+expert-popularity profile from ONE input, an imatrix (core/format/imatrix.h).
+Only the GGUF form carries a per-expert dimension — with the legacy flat form,
+or with none, every expert in a layer is weighted by the layer's aggregate,
+which is exactly the wrong thing on a 512-expert MoE. The calibration tap has
+already measured everything; this tool only re-voices it, so the imatrix and the
+protected-expert census (derive-protected-experts.py) are the SAME recording:
+one measurement, two consumers, neither able to disagree about which experts are
+hot.
+
+INPUT. RADGRAM2 files in a RADIANCE_CALIB_DIR output directory
+(arch/common/rad_arch.h, calib_write). Header law, same parse as
+scripts/derive-protected-experts.py — 32 bytes, `<8sIIQI`: magic `RADGRAM2`,
+u32 k, u32 rank, u64 rows, u32 domain, a pad word, then k*k f32 row-major. Two
+kinds of name, both GGUF-style, both with the checkpoint's GLOBAL expert
+numbering (rad_block_moe_fp8.h: ge = expert_base + e):
+
+    gram.r<rank>.blk.L.ffn_down_exps.bin        the layer's pooled gram
+    gram.r<rank>.blk.L.ffn_down_exps.<e>.bin    expert e's own gram
+
+`rows` is that file's routing/token count and the matrix is Σ x xᵀ over those
+rows, so **the diagonal is exactly the per-column activation second moment an
+imatrix wants**, and `rows` is the count the reader hands back from `count()`.
+Every off-diagonal term is dropped on purpose: the GGUF format has nowhere to
+put a full matrix, and the quantiser asks for columns.
+
+OUTPUT, per layer L (core/format/imatrix.h: names WITHOUT `.weight`, a MoE
+layer's experts folded into ONE entry, so expert 9 is slice 9 of
+`blk.L.ffn_down_exps`):
+
+  blk.L.ffn_down_exps    in_sum2 [k, n_expert] expert-major, counts [1, n_expert]
+  blk.L.ffn_gate_up_exps the SAME matrices at the SAME offsets. A routed expert's
+                         gate_up input is the same hidden-state rows as its down
+                         input, so the second moment over them is identical and
+                         so is the routing count. Two tensor infos over one
+                         payload: the reader maps each half independently
+                         (imatrix.cpp joins `<base>.in_sum2` with `<base>.counts`
+                         by base name), and copying ~200 MB to state one fact
+                         twice buys no correctness.
+  blk.L.ssm_inz          [k] and [1], from the pooled gram: that row's input is
+                         the same hidden state, so its columns take the pooled
+                         diagonal and its count is the layer's pooled rows.
+
+  Then STOP. Nothing whose input width is not the gram's k — no ssm_out, no
+  attn_output, no mtp.*, no ple_ngram. importance_for() answers false when the
+  entry's cols do not equal the weight's width and the convert proceeds without
+  it: an entry the reader silently ignores is a lie in the artifact, worse than
+  an absent one. The corollary to check before trusting the two hidden-width
+  entries: the tap writes the gate_up gram at g.n_embd and the down gram at the
+  expert width, so the gram's k must equal the checkpoint's hidden width (its
+  config.json). Where they differ, gate_up/ssm_inz are inert, not wrong.
+
+INHERITANCE. An expert with no own gram carries the layer's POOLED diagonal, and
+its count stays its own routing rows — the rule the engine itself applies when it
+picks a Hessian (libquant/lq_hess.h, calib_resolve: an expert's own gram only
+once its rank files hold kOwnRowsPerK * K rows; below that a fit to so few rows
+is worse than round-to-nearest, and those experts carry a fraction of a percent
+of the routing). The count never inherits: popularity is `count`'s job. The count
+of inherited experts is reported on stderr.
+
+RANK FOLDING. TP=2 writes gram.r0.* and gram.r1.* with GLOBAL expert numbering,
+so the ranks describe DISJOINT experts and the fold is a UNION into the one
+[k, n_expert] entry. A pooled gram is the opposite case: every rank summed the
+same stem over its own rows, so the fold is a SUM, rows included (calib_sum,
+calib_rows). The same global expert in two per-expert files is legal only when
+the numbers agree exactly; otherwise the recording is corrupt and the entry would
+be whichever file sorted last, so refuse.
+
+GGUF v3 (the only version imatrix.cpp accepts — version != 3 is a refusal):
+`general.alignment` u32, `imatrix.chunk_size` u32, `imatrix.chunk_count` u32,
+`imatrix.datasets` array of strings; tensors f32 (ggml type 0) with offsets
+relative to the aligned data section. Every tensor offset is padded up to
+`general.alignment` and the data section itself starts aligned. That is the
+classic hand-rolled-writer bug: an unaligned offset makes the reader's extent
+arithmetic point into the middle of the previous tensor's floats, and it reads
+them without complaint.
+
+chunk_count DERIVATION. The corpus row count is the LARGEST single-layer pooled
+row total, not a sum over layers: every layer's tap accumulated over the whole
+corpus, so adding the layers counts each token once per layer and inflates the
+figure by the layer count. chunk_count = that row total // chunk_size, the
+"chunks of chunk_size" line imatrix.cpp prints for itself.

+# recording.
+#
+# The reference is the BF16 container built from the vendor checkpoint (run-qwen38-bf16.sh
+# kldref, in the same drained window that records the calibration grams). Every scored
+# container is measured against that one recording, so the KL scale runs from 0 = the
+# checkpoint itself downward in faithfulness.

+# TWO MODES, because the disk decides how many anchors can exist at once:
+#
+#   gate IQ4R.json CAND.json                    candidate vs the served payload
+#   gate FP8.json IQ4R.json CAND.json           the same, inside the absolute interval
+#
+# iq4r.json is the payload frank-archon serves — the bar to beat. When the FP8-native release
+# (172.8 GiB, fetched last because of the peak-disk law) is on disk, pass its report first:
+# "half the gap" is then half of the distance between the 4-bit payload and the near-lossless
+# release, not half of an invented distance to the checkpoint. Without it the gate still
+# answers the campaign's question — does the candidate beat what is served — and says so.
+#
+# The law, on the summary of one slice (--slice all | a corpus source):
+#
+#   candidate vs served (2 reports)
+#   1. mean KL(cand) < mean KL(iq4r)         the served payload is beaten on the corpus
+#   2. p99.9(cand) <= p99.9(iq4r)            and the tail is no worse — a mean can hide a few
+#                                            positions taking the whole hit
+#   3. top-1(cand) >= top-1(iq4r)            the agreement the harness keys on does not fall
+#   4. every source slice passes 1-3         a win bought by regressing one distribution
+#                                            (code, prose, tools) is not a win
+#
+#   inside the interval (3 reports), laws 1-4 above (1-3 renumbered to the interval and the
+#   recovery fraction, as agreed 2026-10-27) plus:

+"""media-apply.py — the only thing that moves movie-library files.
+
+Reads the plan written by scripts/media-plan.py (rows: `action  src  dst  kind`,
+plus `mkdir` rows) and performs it with rename(2) — bytes are never copied, so
+an interrupted run has destroyed nothing. Every run is resumable and every run
+is undoable: the journal is a write-ahead log, one JSON line per intent, fsynced
+BEFORE the rename it authorises. That ordering is the whole design: a crash
+leaves either an intent whose move happened or an intent whose move never ran,
+and both are recognised on the next run. A file that moved with no journal line
+cannot have been moved by this tool, and saying so is better than guessing.
+
+Four subcommands:
+
+    apply    --plan PLAN [--root ROOT] [--journal J] [--apply]
+             no --apply => report only and write NOTHING, not even folders
+    rollback --journal J [--root ROOT] [--apply]
+             back to the paths the census saw; folders this run created are
+             removed only when empty, never anything else
+    verify   --plan PLAN --journal J [--root ROOT]
+             every planned file is at its target with the journalled byte count
+    sweep    --journal J [--root ROOT] [--apply]
+             removes the folders THIS RUN emptied — the journal has to show a
+             file that moved out of one, so a folder someone made by hand can
+             never be removed by this tool, and rollback puts them back
+
+Refusals (exit 2, before the first rename, with nothing touched): a target
+already occupied by a foreign file, a source that has gone, a duplicate target,
+a path outside --root, a journal that was already rolled back, a move that would
+cross a filesystem (rename cannot do it and a silent copy at 24 TB would not).
+
+--force relaxes only the guards that are opinion (journal already rolled back,
+paths outside --root); it never allows overwriting a file.
+
+The journal defaults to `media-relayout.jsonl` BESIDE the library root, never
+inside it: a log inside the library is a file Jellyfin will index.

+           the similar-copies census (DUP / REVIEW / EP-DUP groups) over the
+           ffprobe census scripts/media-census.py writes.

+           before it merges two films into one folder.
+
+scripts/media-plan.py imports this file; over there the paths are arguments.
+
+Method — three independent signals, so a naming accident cannot merge two films:
+  * franchise KEY  : first two significant title tokens. Stable across parts of a
+    collection ("resident evil", "jump street") but NOT film-specific — it only
+    selects candidates.
+  * DURATION       : the identity check. Same master encodes differ by at most a
+    couple of seconds; different films / cuts do not collide.
+  * SIZE SPREAD + YEAR: decide the tier. Two files same size AND same duration
+    are byte-twins (the hash pass confirms); same duration but different sizes are
+    two different releases of one film (deletable redundancy).
+
+TV episodes (SxxEyy in the name) are grouped separately: their uniform runtime
+would otherwise collapse a whole series into one "duplicate" group.

+"""media-tv.py — move TV episodes out of the movie library into a TV library.
+
+`scripts/media-plan.py` refuses to file TV: it parks episode files in a
+`_TV needs a TV library - <series>` pile for a human. This is the other half of
+that refusal. It walks the movie library, groups the files whose own name
+carries an episode marker by SERIES, and writes a plan that places each series
+in the shape both Jellyfin and Plex read without help:
+
+    <library>/<Series> (<year>)/Season <NN>/<the file's own name>.<ext>
+
+It writes a plan and nothing else. Every rename belongs to
+`scripts/media-apply.py` — the write-ahead journal, the refusal to overwrite,
+the all-or-nothing preflight, the rollback. Apply it with `--root` set to the
+share that holds BOTH libraries (`/mnt/entropy`, not `/mnt/entropy/Movies`) so
+the executor's own path guard still has teeth, and give it its own journal —
+one journal is one undo, and a TV move must not be welded to a movie relayout:
+
+    python3 scripts/media-tv.py --root /mnt/entropy/Movies \
+        --library /mnt/entropy/TVShows --out /mnt/entropy/media-tv-plan.tsv
+    python3 scripts/media-apply.py apply --plan /mnt/entropy/media-tv-plan.tsv \
+        --root /mnt/entropy --journal /mnt/entropy/media-relayout-tv.jsonl
+    python3 scripts/media-apply.py verify --plan /mnt/entropy/media-tv-plan.tsv \
+        --root /mnt/entropy --journal /mnt/entropy/media-relayout-tv.jsonl
+    python3 scripts/media-apply.py sweep --root /mnt/entropy \
+        --journal /mnt/entropy/media-relayout-tv.jsonl --apply
+
+Guards, and why each one is here:
+
+* The same five-file threshold as the planner. An episode-shaped name on one
+  file is not a series — `The Godfather Part 2` is a film — so a smaller group
+  is reported and left exactly where it is.
+* An episode whose name carries no season number is reported and left, never
+  filed into an invented `Season 01`.
+* A sidecar that shares an episode's own name (`.srt`, `.nfo`, …) follows the
+  episode; an episode without its subtitles is a half-move.
+* A group that would claim one destination twice is not resolved here. The
+  executor refuses the whole plan before its first rename, which is the right
+  outcome: nobody but Frank decides which copy of an episode is the keeper.
+* An episode the destination library already holds at the same byte count is
+  left where it is. The TV library has held a complete Monk box set for years
+  while the movie library carried a second copy of all 124 episodes; a mover
+  that did not look where it was filing would have put both inside one library.
+* A symlink is never followed and never moved.

+# The SSD-backed metadata view that lets Jellyfin and Plex share one metadata set.
+#
+# Both servers read a Kodi-format sidecar (movie.nfo / tvshow.nfo / episode.nfo)
+# ONLY when it sits next to the media file. The media lives on the RAID6 array at
+# /mnt/entropy — five spinning disks, deliberately mounted read-only for every
+# container, and slow to seek for a thousand tiny XML reads. So neither media
+# server binds the array any more: they bind an OverlayFS merge of it with a
+# writable layer on the NVMe.
+#
+#   lowerdir  /mnt/entropy                RAID6 (ROTA=1) — source of truth, never written
+#   upperdir  /var/lib/media-meta/upper   NVMe — every sidecar and image byte
+#   workdir   /var/lib/media-meta/work    NVMe — kernel bookkeeping
+#   Where     /var/lib/media-meta/view    the merged tree jellyfin and plex bind
+#
+# Everything the view needs — layers, bookkeeping, trash, the merged door — lives
+# under the one directory /var/lib/media-meta, so nothing new appears under /mnt.
+#
+# Consequences worth knowing:
+#   * A sidecar write is a few KB onto the SSD; the media bytes never move and the
+#     array is still never written by anything automated.
+#   * Deleting through the view writes a whiteout into the upper layer instead of
+#     deleting from the array. Nothing should delete through the view: deletions
+#     go to .AGENTTRASH on the RAW path, and `reap` clears the resulting ghosts.
+#   * inotify events on the lower layer do not cross the merge, so a file that
+#     arrives on the raw array is invisible to a file-system watcher in the view:
+#     trigger a library refresh (see the Media Relayout page).

+#!/bin/sh
+# Deterministically empty every .AGENTTRASH directory under the given roots.
+#
+# PURPOSE
+#   The fleet's deletion policy parks deleted files in .AGENTTRASH/ — in-repo
+#   beside the item, elsewhere in $HOME as .AGENTTRASH/YYYYMMDD-topic — and
+#   waits for approval to purge. This script is that purge: given a machine,
+#   it clears .AGENTTRASH directories and nothing else.
+#
+# CONTRACT
+#   Default dry-run: the plan prints and nothing is deleted; --execute deletes.
+#   Every line the script can ever print for a candidate is decided at plan time
+#   and stored in the plan table, so a dry run prints exactly what --execute
+#   will print. A .AGENTTRASH that is a root's own trash (a repo's
+#   .AGENTTRASH, a machine's ~/.AGENTTRASH) prints `plan empty <path>`: the
+#   directory is the convention and survives, its staged contents are cleared.
+#   A .AGENTTRASH deeper than that is content and prints `plan remove <path>`
+#   plus, once executed, `removed <path>`; its own nested .AGENTTRASH entries
+#   belong to that tree and are never planned again. Candidates are found with
+#   `find -xdev` per root, so a mounted tree can never be walked by accident;
+#   ordering is lexicographic (LC_ALL=C). `/`, symlinked, and foreign-owned
+#   candidates are refused and reported (exit 1), never touched.
+#   A summary line `removed=<candidates> deleted=<removed> refused=<n>` closes
+#   every run and one dated line is appended to the log.
+#   Exit: 0 success, 1 operational failure, 2 usage error. A second run over
+#   the same tree plans nothing further and exits 0.
+#
+# PORTABILITY
+#   POSIX sh, clean under `shellcheck -S style`. Externals: find (must support
+#   -delete), stat, rm, date, mkdir. No bashisms, no GNU-only flags, no arrays,
+#   no `local`. Paths containing whitespace are rejected at parse time — the
+#   same rule applied to roots and candidates — so the plan can be walked with
+#   plain word splitting and nothing can be silently mis-split.
+#
+# USAGE
+#   purge-agenttrash [--execute] [--quiet] [--log PATH] [PATH...]
+#   --execute   delete; without it the run is a plan and deletes nothing
+#   --quiet     suppress per-line output; errors and the summary still print
+#   --log PATH  log destination (default: $HOME/.AGENTTRASH-cleanup.log)
+#   PATH...     roots to search (default: $HOME)

+# boot the BF16 rig, wait until it is actually serving, push the corpus until the engine says
+# the tap is full, stop the rig, restore frank-archon, and bank the reference container.
+#
+# The reference recording is already taken (kld-ref/kld.json exists), so this window is the
+# calibration tap alone — the one job that needs both cards after it. The kldref phase is NOT
+# re-run here: the chained launcher that used to do that moved the banked kld-ref into trash
+# first, which is how a 16-hour phase gets paid for twice.
+#
+# Every phase is gated on the previous one, because the last time this ran unguarded
+# (2026-10-29) the rig's boot died of an OOM, the health loop quietly fell through, and the
+# pusher fed four rounds of 10M tokens into RESTORED PRODUCTION with nothing recorded:
+#
+#   1. the runner must still be alive and its container must answer /health AND own the
+#      listening socket, or this script kills it, restores the service and exits non-zero —
+#      no push, ever. The socket clause is not decoration: the runner stops frank-archon
+#      first, the dying process keeps its listener for a moment, and a rig container that
+#      is still loading has not bound the port yet, so `podman inspect` + `/health` both
+#      report success for the WRONG process (measured 2026-10-30: `health ok waited=0s`,
+#      then the pusher refused on the container name and the window died at second zero);
+#   2. the pusher refuses on its own unless the rig wrote its marker into the tap dir, the
+#      marker names this container, and the container is running (scripts/calib-push.py
+#      --tap-marker), so a second lock survives a mistake in this file;

+The three tools move the same two shapes — a JSONL of prompt records and a
+one-artifact JSON manifest — and they all tokenize with the SAME tokenizer. That
+last part is not a detail: a KLD reference is only meaningful against the exact
+token sequence the corpus recorded, so `n_tokens` exists once, here, and every
+tool counts the same way. A window that decode/encode does not round-trip is a
+refusal, never a warning.

+Loaded as a sibling module. Each tool puts its own directory on `sys.path`
+first, so `python3 scripts/<tool>.py` and the driver's container mount

+"""Re-chunk a KLD corpus so every document fits the container that scores it.
+
+A KLD reference is recorded by booting one container and prefilling every corpus
+document through it. radiance refuses a document the KV pool cannot hold on its
+own (core/mem/kv.cpp `can_ever_fit`: a paged group holds `n_blocks *
+block_size` tokens), and the number that matters is printed by the boot ledger,
+not by a flag:
+
+    W kv group 'kv_attn' holds 7436 tokens but the context limit is 32768, so
+    a prompt longer than 7436 tokens is refused (400) ... or lower
+    --max-model-len to 7436
+
+The BF16 qwen4exp container at the campaign's shape gets 270.00 MiB of cache --
+the expert plane owns both cards -- so its real window is 7,436 tokens however
+`--max-model-len` is spelled. The corpus the campaign inherited from the swift15
+era is 197 documents of 8,193-11,970 tokens, because make-calib-corpus.py's
+`--kld-min-prompt 8192` sets a floor and no ceiling: every one of them is
+unscoreable there, and three drained windows have proved it.
+
+This script moves the document boundaries and nothing else. Each record's token
+ids -- counted with the same tokenizer the generator used -- are cut into
+windows of at most `--max-doc-tokens`, so a record's windows concatenate back to
+that record's own token sequence, unchanged: no token dropped, rewritten or
+reworded. Each window gets its own `score_from = len - --score-tail`, the same
+relation the generator wrote for the parent, so the reference scores 256
+positions per window instead of per document: 100,864 measured positions over
+the same text against the 50,432 the inherited corpus scored, at a shorter
+context. The calibration corpus is untouched, so the quantization itself does
+not move.
+
+Usage:
+  rechunk-kld-corpus.py --corpus kld.jsonl --out kld.jsonl.new \
+      [--tokenizer-json PATH] [--max-doc-tokens 7168] [--score-tail 256] [--force]
+
+--out must not exist and be non-empty without --force: the same
+one-artifact-one-name law run-qwen38-bf16.sh applies to a score report. The file
+is written through a temporary name and renamed, so an interrupted run leaves no
+half corpus behind. A JSON summary of what was written goes to stdout.

+#                     THE CAMPAIGN'S RULE (12 M tokens, Frank 2026-10-30): the
+#                     served iq4r this arm competes with was calibrated on a 10 M-
+#                     token set, so the arm is calibrated at least as deeply. One
+#                     round of the re-chunked corpus is ~9.31 M tokens, so sealing
+#                     takes round 1 plus part of round 2 — a round that seals
+#                     nothing is NORMAL (the floor is pooled), and the pusher's
+#                     round_verdict treats a flat round as "continue", never as a
+#                     failure. One seal writes ~40 GiB.
+#
+# Shape: the vendor's bf16 calibration lines — expert_tiered placement with the
+# weights disk tier, deterministic (the resident set pinned to the loader's plan,
+# so a recorded reference and a scored candidate see the same one), no
+# speculation, fp8 KV, a 32,768-token window, the PLE n-gram table pinned to RAM,
+# and the production chat template rather than the one baked into the container —
+# every scored container is asked the same tokenised questions the reference
+# answered. The window the flag spells is 32,768; the pool this payload's boot
+# actually gets is 7,436 tokens, so kld.jsonl is re-chunked by
+# scripts/rechunk-kld-corpus.py into documents of at most 7,168 tokens — the
+# widest one the reference can hold. The kldref gate below re-checks the file
+# against the declared window, and the re-chunker is what keeps that honest.
+#
+# NO --vram-kv-mib: it was REMOVED at 1.3.0 and naming it is a boot refusal, not
+# a no-op — verified on the pinned image 2026-10-27: "E --vram-kv-mib was
+# removed: the card is split between the weights and the cache from what the
+# model needs." The resolver derives the split from --host-pool-mib,
+# --gpu-headroom-mib and the activation arena; the rig inherits the first two from
+# frank-archon.env, the file that owns them. On THIS payload the host pool is not
+# the cache's supplier: the boot lands in vram_budget.cpp's `no lender` branch,
+# where the experts keep their plan-fixed 25.29 GiB and the cache gets the residue.
+# Measured twice — 12,288 and 49,152 MiB of host pool both printed the same
+# "kv cache 271.25 MiB ... 7,436"; only --gpu-headroom-mib moved anything
+# (768 -> 96 grew vram_weights 29.41 -> 30.06 GiB). The supplier the source names
+# is the arena: vram_budget.cpp:117, "lower --max-num-batched-tokens (the arena
+# scales with it)" — which is what the step size below now does.
+#
+# The pool, not the window, decides what the recorder accepts: it refuses any
+# document longer than the pool, so the 32,768-token window was decorative while the
+# cache held 7,436 — "E kld: document 196 is 8507 tokens and the KV pool holds
+# 7436, so it can never be scored" on all 197 records, exit 1. The longest record
+# is 10,554 tokens by the engine's own count (chars/3.6 for this file, not the
+# chars/4.97 this repo measured on the K3 corpus).
+#
+# The step size is ONE value for the recording and every scoring pass, and it is
+# the value frank-archon.env owns (FRANK_ARCHON_MAX_BATCHED_TOKENS, 2,048): the
+# quantised expert FILE tiers (the served iq4r, the arms) stream only at
+# MNBT<=2048 and refuse the widened form above it, and the arena a step costs the
+# card comes straight out of the cache — 1.08 GiB at a 2,048-token step against
+# 504.39 MiB at 1,024. The corpora are cut to the window the boot ledger reports,

+# Media Metadata View
+
+`/var/lib/media-meta/view` is an OverlayFS merge of the media library: the RAID6
+array below, a directory on the NVMe above. It exists so [[Jellyfin]] can write
+Kodi-format sidecars (`movie.nfo`, `tvshow.nfo`, `episode.nfo`, artwork) that
+[[Plex]] can read. Sidecar metadata is only useful sitting next to the media
+file, and the array is read-only and slow — so the media bytes stay there and the
+*writes* land on SSD. One tree to both servers, one copy of the media.
+
+The mount point is not a volume and holds nothing while unmounted. It sits inside
+`/var/lib/media-meta` so that layers, kernel bookkeeping, the reap trash and the
+merged door are one directory — and so the mount table grows no new `/mnt` entry
+next to the array.
+
+## Shape
+
+| Item | Value |
+|---|---|
+| Lower layer | `/mnt/entropy` — the RAID6 array, source of truth, never written |
+| Upper layer | `/var/lib/media-meta/upper` — NVMe; every write lands here |
+| Work dir | `/var/lib/media-meta/work` — overlayfs internals, same filesystem |
+| Mount point | `/var/lib/media-meta/view` — the merged tree both servers bind |
+| Unit (repo) | `dankserver/host/systemd/media-meta-view.mount` — the source of truth |
+| Unit (host) | `var-lib-media\x2dmeta-view.mount` — systemd names a mount unit after its escaped path (`-` becomes `\x2d`); `media-view.sh install` writes the repo file under that name |
+| Installer | `scripts/media-view.sh` — `plan` / `install` / `verify` / `status` / `reap` |
+| Written by | Jellyfin only (Plex binds read-only); nothing else in the fleet touches it |
+
+Both consumers guard the view with
+`UnitConfigItem=ConditionPathIsMountPoint=/var/lib/media-meta/view`, and
+`scripts/deploy.sh dankserver --service jellyfin|plex` calls `media-view.sh
+install` + `verify` before it restarts either container.
+
+| Consumer | Bind | Mode | Why that path |
+|---|---|---|---|
+| [[Jellyfin]] | `/var/lib/media-meta/view:/data` | rw | It is the metadata writer; its sidecars become SSD bytes |
+| [[Plex]] | `/var/lib/media-meta/view:/mnt/entropy` | ro | Every path in the PMS database was recorded as `/mnt/entropy/...`; only the HOST side of the bind moved, so its database still resolves |
+
+Putting the sidecars inside Plex's reach is not the same as making Plex use them:
+a library parses `.nfo` only with its *Local media information* agent enabled, and
+this change touches no library setting.
+
+## Commands
+
+```bash
+scripts/media-view.sh plan              # print the resolved shape, touch nothing
+sudo scripts/media-view.sh install      # create dirs, install the unit, mount, enable
+scripts/media-view.sh verify            # is the view really the overlay? (deploy gate)
+scripts/media-view.sh status            # mount options + upper-layer size/file count
+scripts/media-view.sh reap              # list ghost metadata (media moved, sidecars left)
+sudo scripts/media-view.sh reap --apply # move ghosts to the SSD trash, never delete
+```
+
+`--upper-base DIR` and `--lower DIR` relocate the layers for `plan` and `reap`;
+the defaults are the host values above.
+
+## Laws
+
+- **The upper layer must sit on non-rotational storage.** `install` and `verify`
+  refuse via `lsblk -dno ROTA` if the upper base lives on the array: an overlay
+  whose upper is the spinners is the original problem with extra steps, and it
+  silently turns every metadata write back into a seek.
+- **Never mount the view over an unmounted lower.** `RequiresMountsFor=/mnt/entropy`
+  plus the container `ConditionPathIsMountPoint` guards: an empty `lowerdir`
+  presents an *empty library* as truth, and a media scan would then clear the
+  database of everything. systemd does not create a mount point, so `install`
+  creates `view` itself; without it the mount simply fails.
+- **Never delete through the view.** A delete writes an overlayfs whiteout
+  (`.wh.<name>`) in the upper layer, which hides the array's copy without
+  removing it — the file reappears the moment the view is unmounted, and the
+  upper layer now carries a landmine. Deletions belong on the raw path
+  (`/mnt/entropy`), which the relayout tool already treats as the only writer.
+  `reap` refuses to remove whiteouts and only warns about them.
+- **A relayout must be followed by `reap`.** Renames happen on the raw path, so
+  sidecars the view already wrote stay at the old coordinates: a ghost folder
+  the servers browse and find nothing in. `reap` lists upper-layer directories
+  with no counterpart below and moves them (with their subtree) into a dated
+  `.AGENTTRASH/` under the SSD base. It is recursive and file-safe: a sidecar
+  that exists only above is normal, so only *directories* are candidates.
+- **File-watcher events do not cross the overlay.** Plex's NFO agent and
+  Jellyfin's real-time monitor see inotify events for writes that land *in the
+  upper layer*, not for changes on the array underneath. After any relayout or
+  externally-written metadata, trigger a library refresh — see
+  [[Media Relayout]] for the refresh procedure.
+
+## Failure signatures
+
+| Symptom | Meaning |
+|---|---|
+| `jellyfin.service` / `plex.service` show `ConditionPathIsMountPoint=... was not met` and stay inactive | The view is not mounted. Do not start them anyway: `scripts/media-view.sh install`, then `verify`. |
+| Jellyfin log: `Read-only file system : '/data/Movies/…/movie.nfo'` | The container is binding the raw array, not the view — the quadlet drifted back or the view is gone. `media-view.sh status`. |
+| A folder appears in a media server with artwork/`.nfo` but no video | Ghost metadata from a relayout. `media-view.sh reap`. |
+| `verify` prints `refused: …/view is not a mountpoint` | A plain directory is sitting where the overlay belongs. That is the fail-closed guard working; `install` on the box. |
+| `systemctl status` finds no such unit | Look under the escaped name, `var-lib-media\x2dmeta-view.mount`, not the repo file name. |
+
+## Rollback
+
+Revert the commit that pointed the two quadlets at the view and re-deploy both
+services — they bind `/mnt/entropy` read-only again, which is the pre-view shape.
+The NVMe upper layer can stay: nothing reads it once the binds are back, and it
+holds no state either server needs. Unmounting alone
+(`systemctl stop 'var-lib-media\x2dmeta-view.mount'`) is safe while no container
+binds it, and the array is never modified by any of this.

+# Media Relayout
+
+The movie library on [[Entropy Volume]] arrived as release folders —
+`Some.Movie.2019.1080p.WiKiTaLx.x265-FOO/` with the video inside named after
+the release. [[Jellyfin]] matches a movie by folder and file name, so the
+release noise cost posters, extras and versions. These scripts turn that
+library into Jellyfin's own shape — and move TV back out of it — and nothing
+else in the repo touches a media file.
+
+| Script | Touches media? | Output |
+|---|---|---|
+| `scripts/media-census.py` | reads headers only | `enum`, `probed`, `plex` TSVs |
+| `scripts/media-plan.py` | no — TSVs in, TSVs out | the plan + the exception report |
+| `scripts/media-apply.py` | **renames, never copies**; sweeps only what a run emptied | the moves, plus a journal |
+| `scripts/media-tv.py` | no — TSV out | a plan that moves TV into the TV library |
+
+The seam is `tests/media_relayout.bats`; the target contract is quoted from
+[jellyfin.org/docs/general/server/media/movies](https://jellyfin.org/docs/general/server/media/movies)
+in `media-plan.py`'s docstring.
+
+## Procedure
+
+Run the census on the machine that mounts the library. `probe` is the slow step
+(a header read per container) and is `nice`d — it is safe beside a live service
+because it never competes for the GPU and never writes inside the library.
+
+```bash
+C=scripts/media-census.py
+$C enumerate --root /mnt/entropy/Movies --out /tmp/media-enum.tsv
+$C probe     --enum /tmp/media-enum.tsv --out /tmp/media-probed.tsv --jobs 6
+$C plex      --root /mnt/entropy/Movies --out /tmp/plex-movies.tsv
+```
+
+`plex` reads the Plex metadata cache (`--db` defaults to the path the
+[[Plex]] container bind-mounts at `/var/lib/plexmediaserver`) with
+`mode=ro&immutable=1`: a live server is never locked or written.
+
+Then plan — this reads only the three TSVs, so it costs seconds and can run
+anywhere, including a laptop:
+
+```bash
+scripts/media-plan.py --root /mnt/entropy/Movies \
+    --enum /tmp/media-enum.tsv --probed /tmp/media-probed.tsv \
+    --plex /tmp/plex-movies.tsv --out /tmp/jf-plan.tsv --exceptions /tmp/jf-exceptions.txt

+
+[[Jellyfin]]'s scan key lives in `~/.config/secrets/jellyfin` (mode 600; the
+same value is `JELLYFIN_API_KEY` in the ignored `dankserver/.env`). It rides a
+mode-600 curl config, never a header argument, and it must use the
+`MediaBrowser` form — Jellyfin 12.4 refuses a bare `X-Emby-Token` for any key:
+
+```bash
+umask 077
+{ printf 'header = "Authorization: MediaBrowser Token=\\"%s\\""\n' \
+    "$(cat ~/.config/secrets/jellyfin)"
+  echo 'url = "http://127.0.0.1:8096/Library/Refresh"'
+  echo 'request = "POST"'; } >/tmp/jf.hdr
+curl -s -K /tmp/jf.hdr -o /dev/null -w "jellyfin scan: %{http_code}\n"
+shred -u /tmp/jf.hdr
+```
+
+`204` is acceptance; the scan then runs on the server's own schedule.
+
+## TV in the movie library
+
+A box set that arrives in the movie share stays there until someone moves it:
+`media-plan.py` refuses to file TV and parks each series in
+`_TV needs a TV library - <series>`. `scripts/media-tv.py` is the mover. It
+walks the movie library itself (no census needed), groups episode-shaped names
+by series, and writes a plan in the executor's own format:
+
+```bash
+scripts/media-tv.py --root /mnt/entropy/Movies --library /mnt/entropy/TVShows \
+    --out /mnt/entropy/media-tv-plan.tsv
+scripts/media-apply.py apply --plan /mnt/entropy/media-tv-plan.tsv --root /mnt/entropy
+scripts/media-apply.py apply --plan /mnt/entropy/media-tv-plan.tsv --root /mnt/entropy \
+    --journal /mnt/entropy/media-relayout-tv.jsonl --apply
+scripts/media-apply.py sweep --journal /mnt/entropy/media-relayout-tv.jsonl \
+    --root /mnt/entropy --apply
+```
+
+The shape it writes is the one both matchers read — `Monk (2002)/Season 05/
+Monk - S05E03 - Mr. Monk and the Big Game.mkv` — keeping the file's own name,
+because the publisher's spelling beats a re-derivation, with the year taken
+from the box-set folder. What it refuses it prints and leaves alone:
+
+- fewer than `--min` (5) files under one series name: one file named `Part 2`
+  is a film, not a series;
+- an episode whose name states no season number — no invented `Season 01`;
+- a destination two files both claim: the executor refuses the whole plan
+  before its first rename, and only Frank decides which copy is the keeper.
+- an episode the destination library already holds at the same byte count. The
+  movie share carried a second copy of the whole Monk box set — 124 episodes
+  both sides, the same episode list, every byte count identical, 31.5 GiB each
+  way, and head+tail blake2b identical on a 6-episode sample. The mover leaves
+  such a series in place and says so; a duplicate is deleted or kept by Frank,
+  never copied into one library by a tool.
+
+A sidecar that shares an episode's own name (`.srt`, `.nfo`) moves with it.
+
+Below the threshold the mover prints and leaves, so a lone downloaded episode of
+a real show stays in the movie library on purpose — six did on 2026-10-30.
+Filing one by hand is the same executor on a hand-written plan and the same
+journal; the trap is the series year. Read it from the file's own name or the
+folder it owns, never from the title whose bonus folder it happens to be parked
+in — `The Cleveland Show S03E07` inside `Die Hard (1988)/extras/` is not a 1988
+show. A name whose marker is `Part 2` is a film and stays put.
+
+## Laws
+
+- **A moved file is a 404 in [[Plex]] until its section is rescanned.** The
+  database keeps the release-folder path, so playback fails `Couldn't find the
+  file to stream` while the scanner works through the section. Never read such a
+  404 as a lost file: the file is where the journal says it is.
+- **Plex's matched title outranks the filename**, and a Plex year of `0` means
+  *indexed but never matched* — trusting it named folders `Title (0)`, which is
+  a Jellyfin item with no year, no poster and no identity. A year that is not a
+  plausible year is no information.
+- **`<>:"/\|?*` never survive a name.** Plex's own title for *V/H/S/2* is
+  `V/H/S/2`; kept verbatim it became `Movies/V/H/S/2 (2013)/` — a tree five
+  levels deep that neither matcher reads as a movie.
+- **A folder inside a movie's folder is bonus territory even when its name is
+  misspelled.** `Saboteur (1942)/Exrtas/Saboteur - A Closer Look` is a typo for
+  `Extras`; the vocabulary rule never fired, the featurette became a movie
+  folder, and its words then out-scored the real film and drew that box set's
+  other extras into it. The rule that replaced it needs no metadata: the folder
+  holding the longest film owns the shorter video filed under it, unless that
+  file's own name carries a different year — which is another film speaking.
+- **Matching words are split on everything that is not a letter or a digit.**
+  Splitting on separators but not on `/` left tokens like `(1960)/extras` that
+  no other name could ever agree with, so a film could not be found by the
+  folder holding it, and extras drifted into a neighbour. A bare number counts
+  only when it could be a release year, so `1080` and `2160` never pose as
+  agreement between two names.
+- **Compare two media libraries with the series engine, never a path
+  substring.** Filtering paths for `monk` also returns *Monkey Dust*, and
+  letting whichever file a walk happens to reach first stand for an episode
+  paired two libraries into a fake duplicate — the same sloppiness pointed the
+  other way deletes a file that is unique. The comparison is `media-titles.ep_of`
+  on both sides: series, season, episode, bytes, and a hash before anything is
+  trashed.
+- **A deletion is staged on the item's own filesystem.** The trash rule names
+  `~/.AGENTTRASH`, but `/home` and `/mnt/entropy` are different devices: a 31 GiB
+  stage there is a copy rather than a rename, it has to fit in the 187 GiB of
+  free space, and `rename(2)` refuses it anyway. Trash goes beside the item —
+  `/mnt/entropy/.AGENTTRASH/<date>-<topic>/` — so it costs one inode change and
+  rolls back exactly like the move that made it.
+- **A Jellyfin 401 is the header, not the key.** 12.4 authenticates only
+  `Authorization: MediaBrowser Token="…"` and refuses a bare `X-Emby-Token` for
+  every key, valid or not. This page carried "no credential on this box can
+  trigger a scan, the two Seerr keys answer 401" for weeks because of that
+  header — the keys were innocent. Before believing a 401, prove the key against
+  the server's own table: `select count(*) from ApiKeys where AccessToken = ?`
+  on `jellyfin.db` opened `mode=ro&immutable=1`.
+- **A scan that must see a new folder has to be recursive.** `POST
+  /Library/Refresh` is the incremental pass, and inotify does not cross a
+  rootless podman bind, so folders created on the host stay invisible to it. The
+  move is `POST /Items/{id}/Refresh?Recursive=true` (204) per library, the id
+  from `GET /Library/VirtualFolders` — its field is `ItemId`, not `Id` — and
+  that same record's `RefreshStatus` is the progress read.
+- **A file whose name carries no words is bonus material, not a folder.**
+  `.Extra 1 ( 1H 27min multisub ).mkv` parses to `1`; a movie folder named `1`
+  is not a movie. It becomes a review line telling a human to name the file.
+- **The executor renames and nothing else.** `rename(2)` cannot cross a
+  filesystem, so a plan that would is refused rather than silently copying tens
+  of terabytes.
+- **The journal is a write-ahead log: the intent is fsynced before the rename.**
+  An interrupted run therefore leaves only two states — an intent whose move
+  happened, and an intent whose move never ran — and the next run finishes the
+  job without moving anything twice. A file that moved with no journal line did
+  not move through this tool, and the tool refuses to guess on its behalf.
+- **The journal lives BESIDE the library root, never inside it** (default:
+  `media-relayout.jsonl` next to the root): a log inside the library is a file
+  Jellyfin indexes.
+- **Refusals are all-or-nothing.** An occupied target, a vanished source or a
+  duplicate destination stops the run *before the first rename*, so the operator
+  fixes one thing and re-runs instead of untangling a half-applied plan.
+  `--force` relaxes only the opinion guards; it never permits overwriting.
+- **A sweep deletes only what the journal proves the run emptied.** A folder is
+  eligible when a journalled file moved out of it or out of something under it,
+  it now holds nothing but empty directories, no journalled destination lives
+  beneath it, and it is not a folder the run created. A folder nobody moved —
+  someone's placeholder — cannot be selected at all, and a symlink anywhere
+  inside disqualifies the subtree, because the thing behind a link is not this
+  tool's to delete. Every removal is journalled as `rmdir` and `rollback`
+  recreates the folder, so the sweep is undone by the same command as the moves.
+  Proof carries downward: inside a folder the journal proves emptied, every
+  empty directory goes with it. A release's `Screens/` or `Sample/` is never a
+  move source itself, so 146 of them held their emptied parents on disk after
+  the first sweep.
+  A failed `rmdir` is not a removal: only a folder that is really gone leaves
+  scope, so the next sweep finishes what a permission problem stopped.
+- **An episode-shaped name marks a SERIES, not a film — and the series is the
+  name BEFORE the marker.** `Monk - S05E03 - Mr. Monk and the Big Game` is series
+  `Monk`. Keyed on the whole title instead, every episode became a group of one
+  and never reached the five-episode size that calls something a series, so a
+  box set was filed as 124 movies in 124 folders. The threshold still earns its
+  keep: a lone film named `Part 2` stays a film. Episodes of a series are parked
+  in `_TV needs a TV library - <series>` for a human to move to a TV source —
+  the movie tool never files TV.
+- **One journal is one undo.** The TV move runs on its own journal, and with
+  `--root` set to the share that holds BOTH libraries: the executor refuses any
+  path outside `--root`, and a journal shared with the movie relayout would
+  undo both runs when only one of them is wanted.
+
+- **Sidecar metadata does not follow a rename, because it lives on another
+  filesystem.** The media servers write `.nfo` and artwork through the
+  [[Media Metadata View]] (NVMe upper layer); this tool moves bytes on the raw
+  array path. After any sweep or TV move, run `scripts/media-view.sh reap`, then
+  the same command with `--apply`: the sidecars left at the old coordinates become
+  ghost folders — artwork and an `.nfo` with no video — that both servers browse
+  and report as content.
+- **Nothing deletes through the metadata view.** A delete there writes an overlayfs
+  whiteout in the upper layer, which hides the array's copy without removing it;
+  the file returns when the view is unmounted. Deletions in this pipeline happen
+  on the raw path only, which is what the journal can undo.
+
+## Rollback
+
+One command, from the journal of the run:
+`media-apply.py rollback --journal …/media-relayout.jsonl --apply`. It recreates
+any folder a sweep removed, restores every source path, removes only the folders
+that run created *and that are now empty*, and refuses everything if any moved
+file cannot be accounted for. A rolled-back journal refuses to roll back twice.

-`LlmPrefixCacheCollapse` (`activeAt` 11:10:48Z, value 2.6e-4) when sampled
-minutes later, and was empty again by 11:56Z; the relay logged the matching

-**What that zealot scrape measured on 2026-10-18.** As of ~04:30 PDT the
-production `frank-zealot` root unit was stopped **on purpose** for a benchmark
-window on the 3090 — the repo Benchmarking Policy says stop the production
-service before benching — and `:7771` answered from a manually booted candidate
-arm (`systemctl is-active frank-zealot` → `failed` after
-`stop-sigterm timed out. Killing`, which is llama.cpp ignoring SIGTERM past
-`TimeoutStopSec`, the known shutdown shape for these engines). So
-`up{job="frank-zealot"} == 1` that day measured the trial, not the production
-shape in `scripts/frank-zealot.env` — that shape is [[frank-zealot]]'s to state,
-and it is the repo contract.
-The unit stayed `enabled`; `./scripts/deploy.sh dankclaw --service frank-zealot`
-reinstalls and starts it, restoring boot persistence and self-healing. Never
-quote a candidate arm's flags or VRAM as fleet state — the process and its shape
-changed between two censuses ten minutes apart.

+# Radiance architecture plugins
+
+An architecture plugin declares a model in two phases: `rad_arch_declare` names every weight,
+buffer, KV group and op **once**, against the model's metadata; `rad_arch_step` issues the ops for
+one step. The engine picks the plugin by the exact `(rad_arch_id, rad_arch_quant)` pair — no
+fallback — so one family at two weight formats is two `.so` files, and branching on a quant
+descriptor inside one plugin is the anti-pattern the split exists to prevent.
+
+The in-tree plugins are the templates: `arch/llama_fp8/llama_fp8.cpp` (the smallest complete
+decoder), `arch/gemma3`, `arch/qwen35_bf16`, and the header-only blocks in `arch/common/`
+(`rad_block_attn*.h`, `rad_block_mlp*.h`, `rad_block_moe_fp8.h`, `rad_block_gdn*.h`,
+`rad_block_dflash2.h`, `rad_block_mtp*.h`, `rad_block_vit.h`, `rad_block_ple.h`,
+`rad_block_glm_*.h`, `rad_qsa.h`, …). Include those by `<arch/rad_arch.h>` — they are installed
+beside the ABI and the in-tree plugins include them by that spelling.
+

+`arch/common/rad_arch.h` emits the whole export block, including `rad_plugin_info` (kind
+`RAD_PLUGIN_ARCH`). The plugin's **name must be unique**; the architecture id may repeat.
+
+`rad_arch_serves_imports` exists because a checkpoint whose quantisation was imported weight by
+weight (Quark, ParoQuant, GPTQ, NVFP4) names its producing tool, which no plugin claims: the family's
+one quantised plugin serves it, and two are refused by name. A second quantised plugin that reads
+only its own containers returns 0.
+
+## Declare: the metadata
+
+`RadModelMeta` is what the loader read from the container's header before any plugin ran: `arch_id`,
+`name`, `quant`, `n_layers`, `n_embd`, `n_head`, `n_head_kv`, **`head_dim`**, `n_ff`, `n_vocab`,
+`n_ctx_train`, expert counts, `rms_eps`, `rope_theta`, and a free-form `kv_key`/`kv_val` table for
+everything else (`rad_meta_geti/getf/gets`). Read dimensions from here — one plugin covers every size
+in a family.
+
+**`head_dim` is read, never derived.** On the Qwen hybrids it is 256 while `hidden / heads` is 213;
+a derived value silently breaks projection widths, KV page size and the attention kernel's band.
+
+`RadBuildCtx` is the deployment the plugin must declare against:
+
+| field | meaning |
+|---|---|
+| `rank`, `world_size` | declare runs once per rank; **dimensions are already divided** — the core inserts no collectives |
+| `max_tok`, `max_seqs`, `max_ctx`, `max_spec` | the step bounds: buffer sizing, kernel bands, the scheduler's window |
+| `max_mixed_tok` | the most a multi-sequence step may carry; a wider step is one sequence (prefill span) |
+| `tp_wire_lossy`, `tp_wire_min_bytes` | invert into `all_reduce`'s `exact`; below the floor a message must go exact |
+| `kv_dtype`, `kv_quant` | the attention cache width and, under fp8, its narrow layout (`RAD_KVQ_V4`, `RAD_KVQ_K6V4`) |
+| `attn_prefill_fp8` | `RAD_ATTN_FP8_*` bits to pass as `attn_paged`'s `prefill_fp8` |
+| `kv_resident_blocks`, `kv_stream_ok` | KV streaming: the ring depth, and permission to declare the streamed-only ops |
+| `state_dtype` | `RAD_F16` when `--state-cache-dtype f16` is served by this plugin |
+| `is_draft`, `scope` | a drafter/encoder declare; `scope` prefixes declared names (`draft`, `vision`, `audio`) |
+| `shape_probe` | a **sizing** declare at a smaller `max_tok`; must not touch state the real declare wrote |
+| `max_enc_patches`, `max_audio_frames` | the encoder pass sizes |
+| `max_out_rows` | logits rows the KL mode needs (0 = the plugin's own rule) |
+| `cvec` | the loaded control vector, or null |
+| `tp_attn_rows` | row-split prefill attention requested |
+| `draft_coupling`, `draft_tree` | declare the coupled/tree forms |
+| `weight_prefetch_off` | declare no weight prefetch beside collectives |
+
+## Declare: weights
+
+```c
+static const RadWeightDecl d = {
+    .dtype = RAD_BF16, .rank = 2, .shape = {n_embd, n_ff},
+    .access = RAD_ACCESS_PER_TOKEN, .shard = RAD_SHARD_ROW,
+    .group = grp_layer(l), .optional = 0,
+    .n_row_parts = 0, .source = nullptr, .planes = nullptr,
+};
+rad_weight w = rad_decl_weight(b, "blk.0.mlp.gate.weight", &d);
+```
+
+- **`access`** tells the placement planner how the weight is read: `PER_TOKEN` (dense),
+  `PER_REQUEST` (an encoder tower, read once per request), `CONDITIONAL` (routed experts),
+  `RARE`, `VOCAB` (lm_head/embedding: read every token but huge, and one is a gather).
+- **`shard`**: `NONE` (replicated), `ROW` (split dim 0), `COL` (split dim 1, needs a following
+  all-reduce). The plugin says; the core does not infer. Uneven splits use
+  `rad_weight_shard_span`/`_parts` (a width that does not divide into whole 128-column blocks; the
+  delta net's `[q|k|v|z]` of unequal part widths).
+- **`group`** is the unit of movement (`layer`, `expert`, `slot`); an expert's gate/up/down share one,
+  because the unit of transfer is an expert, not a tensor.
+- **`row_parts`** describes what a `SHARD_ROW` weight stacks along dim 0 (`[gate|up]`,
+  `[q|k|v|z]`). **A tensor-parallel rank owns a slice of each stacked projection**, never a
+  contiguous slice of the stack; the parts cannot be inferred from a fused container tensor, and a
+  contiguous slice produces fluent wrong text.
+- **`source`/`planes`** view an existing stored weight: a block-fp8 linear's `codes,scale` are one
+  logical weight taken by a GEMM as two operands. Null `source` is the weight of its own name; null
+  `planes` takes every plane.
+- A dtype other than the plane's is legal only as an exact widening (a bf16 norm read as f32).
+
+The **name map** (`rad_decl_name_map`) is the plugin's map from checkpoint tensor names to declared
+weight names, and it is the only place convert-time fusions live: `COPY`, `CONCAT`, `WNORM` (a
+weight-normalised pair folded to the plain weight), `ROWS`, `TRANSPOSE`, `EMA` (an EnCodec codebook),
+`TAP`, `COLS`. `rad-convert` reads this map from the plugin, so it needs no knowledge of the model.
+`RAD_MAP_COPY` with several sources means "first present wins" (a tied lm_head); `CONCAT` requires
+all. Ask for a weight's encoding with `rad_weight_encoding` **after** its map entry when the graph
+depends on the format (fp8 GEMM vs plain, rotated expert kernels).
+
+## Declare: buffers and KV groups
+
+`rad_decl_buffer` names every activation: `RAD_BUF_TRANSIENT` (liveness-analysed, may share bytes),
+`RAD_BUF_PERSIST` (across steps: a calibration accumulator, a routing histogram), or
+`RAD_BUF_DERIVED` (computed once per step by the core from the batch — `derive` names the
+derivation, e.g. `conv_state_index`). Buffers live in one arena sized once, not an allocator per
+step.
+
+`rad_decl_kv_group` declares each state kind: `RAD_KV_FULL` (paged per-token, growing),
+`RAD_KV_WINDOW` (bounded by a window), `RAD_KV_LINEAR` (per-sequence fixed state, GDN),
+`RAD_KV_CONV` (a rolling window of `width-1+num_spec`), `RAD_KV_RING` (window floor set at runtime).
+The **block size is not declared** — it comes from the resolved attention kernel's constraints; read
+it back with `rad_kv_block_size`. `rad_bind_layer_kv` binds each layer so the block manager knows how
+many state instances a sequence owns; `rad_kv_group_zero` (a rank with no heads),
+`rad_kv_group_replicated` (every rank holds the same bytes), and `rad_kv_group_dense_read` (read over
+the whole history every step, so it cannot stream) are the three refinements.
+
+## Declare: ops
+
+```c
+rad_op h = RAD_OP(b, "gemm_w4a8_nt",
+                  RAD_PARAMS(RAD_RANGE("M", 1, max_tok), RAD_INT("N", 8192), RAD_INT("K", 5120)),
+                  RAD_WEIGHTS(w));
+rad_op_reads (b, h, RAD_BUFS(b_x), n);
+rad_op_writes(b, h, RAD_BUFS(b_y), n);
+```
+
+- Parameter names and operand order come from `docs/OPS.md`; a new name is allowed only when the
+  vocabulary has none, and the first plugin to declare it fixes its schema.
+- `RAD_RANGE` on exactly one parameter per op gives the selector its bucket table. The core carries
+  every parameter opaquely except `RAD_PROLE_SEQ_CHUNK` (cut steps on it) and `RAD_PROLE_CAPACITY`.
+- `rad_op_reads`/`rad_op_writes` are the buffer planner's liveness. An undeclared use is assumed live
+  for the whole program: sound but wasteful.
+- **Fusion is selection.** Ask for the fused op; if `rad_op_resolved` is false, emit the chain. A
+  fusion's `replaces` hook is a checkable equivalence, not a rewrite.
+- `rad_op_declared(b, "op")` asks whether any library declares an optional op; use it before
+  emitting a fused form only an optional library defines.
+- Buffers touched from the **second lane** go through `rad_buf_concurrent`, and an architecture whose
+  lane-1 work lies in one stretch declares `rad_lane1_window_begin/end` around it. The runtime
+  refuses a lane-1 op outside the window; the window lets buffers used only outside it share bytes.
+
+Step output: `rad_declare_logits` names the buffer the sampler reads (its dim 0 bounds `n_out`; a
+[n_tok, vocab] logits buffer at a large vocabulary is gigabytes — declare the gather +
+`logits_gemm` shape instead). An embedding program declares `rad_declare_pooled` instead (one row a
+sequence, no sampler, no generation). `rad_declare_scores` opts into host-side scored steps.
+
+## Declare: drafters, encoders, generators
+
+- `rad_declare_drafter(RadDrafterDecl)` — depth, block, proposal shape. `rad_drafter_shared_kv` (a
+  drafter with no cache of its own), `rad_drafter_tree` (a tree over the proposals),
+  `rad_drafter_short_block` (a second, shorter pass) are refinements. Declare the drafter **last**.
+- `rad_declare_encoder(RadEncoderDecl)` — a vision/audio tower, media preprocessed by the core.
+- `rad_declare_generator` / `rad_declare_audio_generator` / `rad_declare_video_generator` — image,
+  audio and video generation programs; the engine sizes the step from the probe's `gen_*` fields
+  before declare.
+- Optional format exports let a model state what it knows and the server learn nothing new:
+  `rad_arch_chat_format` (a data description of reasoning/tool-call markup, replacing template
+  analysis), `rad_arch_audio_format` (how a speech model hears: clip tokens, prompt, language,
+  transcript start), `rad_arch_text_prepare` (rewrite request text into training form),
+  `rad_arch_video_positions`/`rad_arch_video_pack` (video pass geometry and packing),
+  `rad_arch_encode_geom` (encoder pass geometry). Each struct grows only at its end behind
+  `struct_size`, so adding a field does not move the ABI.
+
+**Media preprocessing is the core's**, not the plugin's: resizing, patching, placeholder expansion
+and positions in six processor families (Qwen-VL, Gemma 4, LFM2-VL, Unlimited-OCR, GLM-5.3, Pixtral
+for Nemotron), chosen by `vision_config.model_type` plus owning-model checks; audio through Gemma 4's
+extractor or Qwen3-ASR's Whisper one, chosen by `audio_config.model_type`. A vision model with another
+pipeline needs a core change.
+
+## Step: issuing the graph
+
+`RadBatch` is built once per step and shared by every block: `phase` (`PREFILL`/`DECODE`/`MIXED`),
+`n_tok`, `n_seq`, `token_ids`, `positions`, `cu_seqlens`, `seq_ids`, `lora_slot`, `n_out`/`out_ids`,
+`q_lens`/`ctx_lens`/`max_q_len`/`max_ctx_len`, the KV-group array, the speculative fields
+(`n_spec`, `draft_pass`, …).
+
+```c
+static void step(RadCtx* c, const RadBatch* batch) {
+    if (batch->draft_pass > 0) { m.ds.step(c, batch); return; }      /* query pass */
+    if (batch->draft_pass < 0) { m.ds.context(c, batch); return; }   /* context pass */
+    RAD_ISSUE(c, m.op_embed, praw(batch->token_ids, RAD_I32, batch->n_tok),
+              RAD_W(m.w_tok), brows(m.b_x, batch->n_tok));
+    for (auto& layer : m.layers) { layer.attn.step(c, batch); layer.mlp.step(c, batch); }
+    /* ...heads; the lm_head only over batch->n_out rows... */
+}
+```
+
+- `rad_issue(c, op, operands…, n)` / `RAD_ISSUE` (n = the batch's ranged extent) /
+  `RAD_ISSUE_N` (an explicit row count). `rad_step_fail(c, what)` sets the status helpers return.
+- **A mixed step is the trap.** Continuous batching produces steps with a prefill chunk beside decode
+  rows. A block that issues one path for the whole step sends its decode rows down the chunked path,
+  which commits recurrent state directly and takes no `num_accepted`; a rejected draft cannot be
+  rolled back, and the model stays fluent while drifting. Issue the recurrent path over
+  `RadBatch::n_seq_decode` sequences and the chunked path over the rest (the core orders steps
+  decode-first, so each half is contiguous; `cu_seqlens` holds absolute offsets, so pass
+  `cu + n_seq_decode` with the token operands at their base).
+- A step issued on lane 1 outside the declared window fails by name. An op the core appends behind a
+  declared one (runtime LoRA) counts at that op's position.
+- **Zero rows is not a call**: issuing an op over zero rows (a zero ranged extent, or all-empty
+  sequences) returns `RAD_E_SHAPE` and writes nothing. The caller skips the issue, as the
+  architectures' decode and prefill halves do.
+- `n_out` is 0 for a chunk that finishes no sequence — do not run the lm_head.
+
+## Probe: what the plugin measured
+
+`rad_arch_probe(meta, out)` runs before declare. Its fields are the engine's permissions:
+
+| field | effect |
+|---|---|
+| `draft_depth`, `draft_depth_fixed` | the container's spec depth; a block drafter's trained block is the only depth it serves |
+| `shape_probe_ok` | the plugin tolerates a sizing declare, so the activation arena can be lent |
+| `enc_merge`, `audio_frames` | encoder pass granularity; longest audio clip |
+| `gen_rows`, `gen_patches`, `gen_audio`, `gen_ctx`, `gen_video` | generator sizing before declare |
+| `kv_quant_ok` | bits of the narrow KV layouts this model's kernels serve |
+| `chain_pays`, `tree_pays` | the plugin measured chained launches / draft trees faster |
+| `kv_stream_ok` | the architecture can stream a KV group (sparse, block-addressed, with `kv_resolve`) |
+| `control_vector_ok` | the plugin applies `RadBuildCtx::cvec` |
+| `tp_attn_rows_ok` | the plugin serves row-split prefill attention |
+| `state_f16_ok` | the plugin declares recurrent state at f16 and its kernels read it |
+
+A flag whose probe bit is 0 is **refused at startup with the plugin named** (`--kv-cache-dtype
+fp8_v4`, `--control-vector`, `--tp-attn-split rows`, `--state-cache-dtype f16`, `--kv-resident`).
+That is the design: a deployment switch the plugin cannot honour is an error, never a silent
+substitution.
+
+## Worked pattern: the smallest complete plugin
+
+`arch/llama_fp8/llama_fp8.cpp` builds twice from one source — `llama_fp8` (quant `fp8_e4m3`) and
+`llama_dense_fp8` (quant `""`), differing only in the descriptor and the graph-dump text. It shows
+the whole shape:
+
+1. `struct Layer { AttnFP8 attn; MlpFP8 mlp; }`, `struct Model` holding `Names`, `Geom`, buffer and
+   op handles.
+2. `declare()`: name map entries first, then weights (with `rad_weight_encoding` where the head's
+   format decides the kernel), buffers, KV group, the embedding and its all-reduce, then each layer's
+   `declare()` from the shared blocks, the final norm, gather and lm_head, **the drafter last**, and
+   `rad_note` lines explaining the shape.
+3. `step()`: draft passes first (sign selects query/context), then embedding (+ exact all-reduce
+   when needed), each layer's `step()`, the final norm, and the head only over `n_out`.
+4. `probe()`: reads `draft.block_size` from the metadata and refuses any other depth for a block
+   drafter.
+5. `RAD_ARCH_PLUGIN(...)` at the bottom.
+
+Add a new family by copying a neighbour, replacing the name map and geometry, and composing the
+blocks you need; add a new *format* by cloning the plugin with another `(id, quant)` pair and the
+ops that format needs.
+
+## Verifying a new plugin
+
+```sh
+radiance --model m.rad --debug-graph          # every op, its resolved kernel, and why
+radiance --model m.rad --debug-placement      # the plan
+rad-convert $SRC -o m.rad --plan-only -v      # a convert that plans will boot
+rad-kbench -m m.rad --kernels mylib,libr4d,libref --report k.md --bench
+rad-tune -m m.rad --tp 2                      # only at the shapes you serve
+```
+
+`tests/arch_test.cpp` drives a plugin's builder the way the core does, including lane-window
+liveness, so the pinned graphs and steps are the ones the core plans. A plugin that declares a weight
+form no kernel `layout` accepts is a declare-time error naming the weight, encoding and kernel — the
+same check `rad-convert` runs before writing.

+# Radiance conversion
+
+`rad-convert` turns a Hugging Face checkpoint into a `.rad` container, choosing each weight's
+encoding from a **recipe**. `rad-export` wraps it for finetunes (a merged checkpoint or a PEFT
+adapter) with the stock model's recipe. Neither opens a GPU: conversion is CPU-only and safe beside a
+running server.
+
+Fetch checkpoints with `scripts/hfget.sh <org/repo> <dir>` (resumable; reads `.safetensors`,
+skips `.bin`/ONNX/GGUF when safetensors exist; `HF_TOKEN` for gated repos; writes a
+`.hfget-manifest` of content keys). `radiance --model <owner/name>` runs the same fetch itself.
+
+## What a conversion does
+
+1. Read `config.json` (or GGUF metadata), and the shard index if present.
+2. Load the architecture, kernel and quantiser plugins and run **declare**, as the engine does.
+3. Resolve every op and ask each resolved kernel's `layout` hook about the planned encoding. A
+   recipe no kernel can serve is refused **here**, before any I/O.
+4. Write each logical weight once: the checkpoint's bytes where no rule matches, otherwise the
+   planes the matching quantiser writes, a block of rows at a time.
+5. Measure every quantised weight against its source through the core's decoder and print the worst.
+6. Bake the tokeniser, chat template, metadata, recipe and any draft head.
+
+```sh
+build/bin/rad-convert /srv/models/hf/Qwen/Qwen3.8-27B -o qwen3.8-27b-bf16.rad \
+    --recipe data/recipes/q38-27b-bf16.recipe
+build/bin/rad-convert /srv/models/hf/Qwen/Qwen3.8-Flash-Next -o flashnext-bf16.rad --max-ctx 4096
+```
+
+## Every `rad-convert` option
+
+| option | meaning |
+|---|---|
+| `<input>` | a `.gguf`, a `.safetensors`, an `index.json`, or a checkpoint directory |
+| `-o, --out FILE` | the container to write |
+| `--recipe FILE` | one rule a line: `PATTERN QUANTISER key=value …`; repeatable; first match decides |
+| `--quant RULE` | `PATTERN=QUANTISER[:key=value,…]`, placed **ahead of** the recipe's rules; repeatable |
+| `--list-quantizers` | every loaded quantiser and the options it takes, then exit |
+| `--arch ID` | override the architecture id read from the checkpoint |
+| `--home DIR` | `$RADIANCE_HOME` (kernels, architectures, quantizers) |
+| `--kernels A:B` | kernel libraries to load, first wins; declare checks the recipe against them |
+| `--tokenizer F` | `tokenizer.json`; its declared chain is baked instead of reconstructed from a pre-tokenizer name. Required for a GGUF, without it the chain is a guess |
+| `--tokenizer2 F` | a second `tokenizer.json` baked as the second vocab (a generator reading its prompt through two tokenisers); keep `tokenizer_config.json` beside it |
+| `--add FILE` | merge one more `.safetensors`, tensor names kept; repeatable; a name in two files is refused |
+| `--config DIR` | read `config.json`, `generation_config.json`, `tokenizer.json` from DIR for a single-file checkpoint |
+| `--chat-template F` | a Jinja template baked in, overriding the checkpoint's (or its absence); trailing newlines stripped; without one `/v1/chat/completions` answers 501 |
+| `--imatrix F` | llama.cpp imatrix: expert-popularity profile, per-column importances, error weighting; required by `ggml` types `iq2_xxs`, `iq2_xs`, `iq1_s` |
+| `--set K=V` | a metadata key, seen by declare **and** written into the container; repeatable |
+| `--max-tok N` | the `max_tok` declare runs at (default 8192, or a generator's largest pass) |
+| `--max-ctx N` | the context declare runs at (default: the checkpoint's training context) |
+| `--max-spec N` | the `max_spec` declare runs at (default 4, or the block a drafter states); `0` leaves a draft head out |
+| `--draft-model DIR` | a drafter shipped as its own repository, merged under `draft.` |
+| `--kv-cache-dtype T` | `bf16` or `fp8`: the cache width declare runs at; the container is identical at either |
+| `--reuse FILE` | copy every weight an earlier container holds with the same encoding, quantiser, options and shape |
+| `--changed FILE` | with `--reuse`: checkpoint tensors (one name a line) that differ; every weight reading one is converted |
+| `--in-place` | with `--reuse`: extend that container; new weights go past its end, the header last; keeps `<file>.pre-append` |
+| `--lora FILE\|DIR` | merge a PEFT adapter into the checkpoint tensors before converting (`W + strength · scale · B·A`); repeatable, merged in order; each merged tensor joins `--changed` |
+| `--lora-strength F` | strength for every `--lora` (default 1) |
+| `--lora-map FILE` | JSON map for adapters whose module names differ: `{"strip":[prefix…],"modules":{"<pat>":[target…]}}`; one `*` matches a block index; several targets mean a fused module (rows split in order) |
+| `--plan-only` | declare, plan every encoding, print the plan, stop before writing |
+| `--report N` | print the N worst quantisation errors (default 20) |
+| `-v, --verbose` | per-weight detail |
+
+`--reuse` matches a weight on its **encoding, quantiser, options and shape — not on its source
+bytes** — and carries whatever calibration made the old planes. Use it only when source and
+calibration are unchanged, or name the changed tensors with `--changed`. `--in-place` refuses to
+change a weight the container holds or to add an expert.
+
+## The recipe language
+
+```
+# PATTERN                      QUANTISER  OPTIONS
+blk.*.ffn_*_exps.*.weight      gptq       codes=i4 group=128 scale=bf16 transform=fwht128 calib=$CALIB
+blk.*.ple_ngram.weight         rtn        codes=fp8_e4m3 block=*x* scale=bf16 rule=fixed scale_value=1.99317932128906e-4
+output.weight                  rtn        codes=fp8_e4m3 block=128x128 scale=bf16
+blk.*.weight                   rtn        codes=fp8_e4m3 block=128x128 scale=bf16
+```
+
+- One rule a line: `PATTERN QUANTISER [key=value …]`. `#` starts a comment.
+- `PATTERN` is a glob over the **whole logical weight name**: `*` crosses dots, `?` is one character.
+- **The first matching rule decides.** No rule → the checkpoint's own encoding, which must be one
+  the engine serves as is: `bf16`, `f16`, `f32`, or block-scaled FP8 (`X.weight` with
+  `X.weight_scale_inv`). Anything else is named and refused.
+- `$NAME` / `${NAME}` in a value comes from the environment; an **unset variable is refused**, never
+  expanded empty (so an empty `$CALIB` cannot silently produce an uncalibrated convert).
+- A quantiser may **decline** a weight (`RAD_E_UNSUPPORTED`), which keeps the checkpoint's encoding
+  — `rtn` declines a rank-1 tensor, so a pattern that also matches a norm leaves the norm alone.
+- An option the quantiser does not declare is refused, by name, before anything is quantised.
+- Two plugins naming the same quantiser are refused, both named.
+
+## Quantisers
+
+| quantiser | what it does |
+|---|---|
+| `rtn` | round to nearest on a grid; each block's scale chosen by `rule` |
+| `gptq` | error feedback against the layer's input Hessian (`calib=DIR`, damped by `damp` = 0.01 of the mean diagonal by default); `act_order=1` quantises columns by descending input energy and stores the permutation; `cd=N` adds coordinate-descent sweeps |
+| `awq` | per-input-column scaling to a searched power, then a per-block clip search, both against the Hessian; column scales are the last scale level |
+| `autoround` | sign-gradient descent on a rounding offset per value and a range factor per block; `iters` steps; slow (a 27B dense model takes most of a working day at defaults; `iters=50` a quarter) |
+| `paroquant` | channel scaling plus `stages` Givens rotations learned against the Hessian, then AutoRound on the rotated weight; the `givens` transform |
+| `m2xfp4` | M2XFP's weight-side Sg-EM: MXFP4 plus one metadata byte per group of 32; its own `m2xfp4` scheme; `adaptive=0` pins the bias, `wide=1` widens it |
+| `ggml` | a llama.cpp format (`q4_0`, `q4_1`, `q5_0`, `q5_1`, `q8_0`, `q2_K`…`q6_K`, `iq4_nl`, `iq4_xs`, `iq2_xxs`, `iq2_xs`, `iq2_s`, `iq3_xxs`, `iq3_s`, `iq1_s`, `iq1_m`), by llama.cpp's own search, imatrix-weighted, codes byte for byte |
+| `cast` | a float weight in another float dtype (`dtype=` f32, bf16, f16, fp8_e4m3, fp8_e5m2), no scale |
+| `import` | rad-convert's own, not a plugin: write the numbers a quantised release ships, in the spelling the kernels read, instead of quantising again |
+
+Every quantiser except `m2xfp4`, `ggml`, `cast` and `import` takes the grid options:
+
+| option | values |
+|---|---|
+| `codes` | `i2`…`i8`, `i16`, `i32` symmetric; `u1`…`u8`, `u16` with `zero=`; `fp8_e4m3`, `fp8_e5m2`, `fp6_e2m3`, `fp6_e3m2`, `fp4_e2m1` |
+| `table` | a codebook the codes index: `nf4`, `iq4nl`, `w4nl`, `w5nl`, `binary`, `ternary`, or `;`-separated values |
+| `group=N` / `block=RxC` | where the scales sit; `*` is a whole extent |
+| `scale` | f32, bf16, f16, fp8_e4m3, e8m0; under `scale2` also an integer sub-scale `u4`…`u8`, `i6`, `i8` |
+| `scale2`, `group2` / `block2` | a second scale level the first is relative to (default the whole tensor) |
+| `scale2_value` | the second level fixed at this value, exact in `scale2`'s dtype |
+| `zero` | an integer zero point per block — an asymmetric grid |
+| `transform=fwhtN` | rotate each row by the Hadamard first |
+| `rule` | `absmax`, `mx` (OCP shared exponent), `fixed` (`scale_value=`), `search` (least squared error over candidates and refits, imatrix-weighted) |
+| `clamp` | a signed code's range: `full` or `sym` |
+
+Named grids: MXFP4 = `codes=fp4_e2m1 group=32 scale=e8m0`; NVFP4 =
+`codes=fp4_e2m1 group=16 scale=fp8_e4m3 scale2=f32`; NF4 = `table=nf4 group=64`; a K-quant-like grid
+= `codes=i4 group=32 scale=u6 scale2=f16 group2=256`; a ternary BitNet weight = `table=ternary`.
+
+**A container can hold only what some kernel reads.** rad-convert checks every planned encoding
+against the `layout` hooks of the kernels declare resolved and refuses one no kernel accepts. libr4d
+reads the plain floats; block-scaled fp8 and fp8 rows; int8 block rows plain or rotated; routed
+experts as fp8, int4 (`i4*bf16[1x128]/fwht128`) or the `w4nl`/`w5nl` codebooks under E4M3 scales;
+the dense w4, w8 and mxfp4 GEMM rows; and the 2-bit draft head. See [[Radiance Plugins]] for the
+encoding model.
+
+## Importing a release someone else quantised
+
+These forms are read weight by weight and written in the spelling the kernels read; a recipe rule
+re-quantises from the exact dequantisation where the family's kernels want another form.
+
+| `quantization_config` | read as | notes |
+|---|---|---|
+| `quark` MXFP4 (fp4, group 32, e8m0) | `fp4_e2m1*e8m0[1x32]` | byte for byte; also servable as it stands |
+| `paroquant_mxfp4` | `fp4_e2m1*e8m0[1x32]/givens` | codes/exponents byte for byte plus learned rotations as `givens` tables |
+| `paroquant`, `int5-bitplane`, plain `paroquant` | `u5*f16[1x128]-u8[1x128]/givens`, `u4*…` | AWQ-packed nibbles re-laid as a code bit stream; f16 scales, integer zeros, rotations |
+| `compressed-tensors` `pack-quantized`, 4-bit `int`, group, act-order none/static/weight | `i4*<scale>[1xG]` | `weight_packed` made signed beside `weight_scale`; group/dynamic reorder is refused |
+| same with `symmetric:false` (AWQ) | `u4*<scale>[1xG]-u4[1xG]` | nibbles plus `weight_zero_point`, bit for bit |
+| `auto-round` `auto_round:auto_gptq`, `gptq` v1 | `i4*bf16[1x128]` or `i8*bf16[1x128]` | scales rounded to bf16; convert-time; `import` keeps shipped f16 |
+| `nvfp4-pack-quantized` | `fp4_e2m1*f32[1x16]` | `weight_scale / weight_global_scale`; **no kernel serves NVFP4**, so it always takes a rule |
+| `modelopt` NVFP4 / FP8 / MIXED_PRECISION | NVFP4 `fp4_e2m1*f32[1x16]`; FP8 `fp8_e4m3*f32[1x*]` | ModelOpt's second scale **multiplies**; `input_scale` is not read |
+| compressed-tensors all-FP8 groups | `fp8_e4m3*<scale>[1x*]` or `[RxC]` | nothing imported: stock FP8 with its scale; a per-tensor scale is written once a row |
+| GGUF `Q8_0`, `Q4_K`, `Q6_K` | `i8*f16[1x32]`, affine u4/u6…, `i6*i8…` | blocks split bit for bit; **not servable as they stand** |
+
+The width is read **per tensor**, so a mixed release imports int4 experts and int8 projections
+together. What an import cannot read (an asymmetric GPTQ zero point, a group-reordering act-order
+index, a GPTQ group under 128, a missing/zero global scale, an unlisted format) is refused by name.
+The release's `quantization_config` names the tool, not a served form, so it is kept as
+`imported_quantization_config.*`.
+
+`import` options: `codes=uN` makes a symmetric grid unsigned under a zero point of `2^(N-1)`;
+`zero=` the zero plane's dtype (`u4`, `u8`); `scale=` f16/bf16/f32, each shipped scale rounded to
+nearest; `block=RxC` repeats an FP8 scale shipped per row/tensor over that grid. It reads an imported
+integer grid or FP8 with a per-row/per-tensor scale and keeps a plain float weight as it is.
+
+**NVFP4 to MXFP4 rounds twice** (e4m3 per 16 → power of two per 32), so it loses more than MXFP4 made
+from bf16. Prefer a calibrated MXFP4 container when one exists; the quality verdict is a KL gate, not
+a file size.
+
+## The descriptor law (`--set`)
+
+The architecture plugin is chosen by the exact `(arch id, quant descriptor)` pair. A convert-time
+choice that must also hold at serve time is stated once with `--set`, which hands it to declare and
+writes it into the container. Storage format is not such a choice (the encoding is in the container
+and the plugin reads it there), but the **serving plugin** is: a `quantization_config.*` key
+re-derives the descriptor.
+
+```sh
+rad-convert <bf16 Qwen3.8-27B> -o q38-27b-fp8.rad \
+    --recipe data/recipes/q38-27b-fp8block-df2.recipe \
+    --set quantization_config.quant_method=fp8 --set quantization_config.fmt=e4m3 \
+    --set "quantization_config.weight_block_size=128 128" \
+    --set quantization_config.activation_scheme=dynamic
+```
+
+A bf16 checkpoint whose recipe writes Qwen's block FP8 must therefore be declared *as that format*;
+otherwise the selection pair does not match any plugin and the convert (or the boot) is refused. The
+same law bites the other way when a release's own `quant_method` names a pair no plugin claims.
+
+## Inspect and validate the result
+
+```sh
+rad-info out.rad                  # architecture, source quant, recipe, sections
+rad-info --recipe out.rad         # the expanded rules — did the intended one win?
+rad-info -v out.rad | head -40    # every tensor, its encoding, and what made it
+rad-kbench -m out.rad --home $RADIANCE_HOME --report kbench.md
+radiance --model out.rad --debug-graph     # every op resolves
+```
+
+The converter's own error report (the worst `--report N` weights) measures each quantised weight
+against its source through the core decoder. `rad-kbench` adds the artifact test: weight operands
+read from the container and passed through each kernel's `layout`/`relayout` hooks. Both are on
+[[Radiance Tools]].
+
+## Calibration (GPTQ, AWQ, AutoRound, ParoQuant)
+
+`calib=DIR` is a directory an engine run wrote with `RADIANCE_CALIB_DIR` set: each layer's **Gram
+matrices of its input**, in the domain the kernel multiplies it in. A block that characterises an
+activation declares an f32 `[K,K]` PERSIST buffer and a `gram_accum` op; at `RADIANCE_CALIB_TOKENS`
+(default 65536) the run writes the files.
+
+Three-step bootstrap: convert with plain `rtn` → serve that container with `RADIANCE_CALIB_DIR` →
+push real prompts through prefill → convert again with the Hessians. The second moment is robust to
+the first container's small quantisation error. A weight with no file is quantised uncalibrated and
+the converter says so; `awq`, `autoround` and `paroquant` fall back to the imatrix diagonal when one
+is given.
+
+- The accumulator must be **PERSIST**: a transient buffer may share bytes and be overwritten between
+  the launches it sums.
+- Files are per rank; the consumer sums them. Under expert parallelism a rank's `down` input covers
+  only its experts' tokens; `gate_up` input is the full token set on every rank, so the sum scales
+  `H` by world size — GPTQ is invariant to a positive scale.
+- Under tensor parallelism a column-split linear sees only its rank's columns, so a tap may write
+  `gram.r<rank>.<stem>.part.bin`; libquant places the parts on the diagonal in rank order, leaving
+  cross-rank products zero. They must cover K and be in the model's own domain.
+- `--imatrix` supplies the expert-popularity profile the placement planner ranks units by, the
+  per-column importances a quantiser uses, and the error report's weighting.
+
+## Reuse, drafters, merging
+
+```sh
+# re-quantise only what changed
+rad-convert $SRC -o new.rad --recipe new.recipe --reuse old.rad --changed changed.txt
+
+# merge a drafter shipped as its own repo (DFlash2, DSpark, MTP assistant)
+rad-convert $SRC -o out.rad --draft-model /srv/models/z-lab/Qwen3.8-27B-DFlash2 \
+    --recipe data/recipes/q38-27b-mxfp4-df2.recipe
+
+# merge a PEFT adapter at convert time
+rad-convert $SRC -o tuned.rad --lora ~/run/adapter --lora-strength 1.0 \
+    --recipe data/recipes/q38-27b-mxfp4-df2.recipe
+```
+
+- A drafter's tensors go in under `draft.`, its config under `draft.` keys. It has no embedding and
+  no `lm_head` of its own; it uses the target's.
+- `--lora-map` exists for adapters trained on names the checkpoint does not use; a fused target
+  (`qkv`) takes several targets and splits the adapter's rows in order.
+- `--add` + `--config` + `--tokenizer2` assemble a ComfyUI-style release of separate single files
+  (Anima: diffusion model, text encoder, VAE). A name in two files is refused.
+
+## `rad-export` — finetunes without hand-writing the command
+
+```sh
+rad-export ~/outputs/my-run/checkpoint-400 --dry-run   # what it would run
+rad-export ~/outputs/my-run/checkpoint-400             # adapter -> <name>.rad
+rad-export ~/exports/merged -o ~/models/mine.rad --recipe q38-27b-fp8block-df2
+```
+
+| flag | default | meaning |
+|---|---|---|
+| `SRC` | required | a merged 16-bit checkpoint (`config.json` + `*.safetensors`) or a PEFT adapter (`adapter_config.json` + `adapter_model.safetensors`) |
+| `-o, --out FILE` | SRC's folder name + `.rad`, beside SRC or in `out_dir` | the container |
+| `--recipe NAME\|FILE\|auto` | `auto` | a recipe name, a file, or the one recipe whose header names the base model, takes a bf16 checkpoint and needs no calibration |
+| `--base DIR` | the adapter's `base_model_name_or_path`, from disk or the HF cache, else downloaded | the base a LoRA merges into |
+| `--draft DIR\|ORG/NAME` | the config, else the Hub repo the recipe's usage line names | the drafter when the recipe merges one; a usage line with a placeholder asks for `--draft` |
+| `--image IMAGE` | `$RADIANCE_IMAGE`, the config's, then `stilldeadcode/radiance` | run `rad-convert` in this image (docker, CPU-only, no network, **not pulled**) |
+| `--rad-convert PATH` | — | run this binary instead of docker; recipes come from its `share/radiance` |
+| `--memory M` | — | docker memory limit for the convert |
+| `--dry-run` | — | resolve recipe, drafter and paths; print the `rad-convert` line; write nothing |
+| `--keep-merged` | — | keep the merged checkpoint beside OUT |
+| `--config FILE` | `~/.config/rad-export/config.json` | the config below |
+| `--list-recipes [--json]` | — | list the recipes the image/installed tool carries |
+
+- Input: a merged 16-bit checkpoint (`config.json` + `*.safetensors`) or a PEFT LoRA adapter
+  (`adapter_config.json` + `adapter_model.safetensors`).
+- An adapter is merged **exactly as PEFT's `merge_and_unload`** computes it on CPU: `scale` =
+  alpha/r (alpha/√r with rsLoRA), `rank_pattern`/`alpha_pattern` honoured, delta in fp32 rounded to
+  the adapter's dtype. It streams tensor by tensor into 1 GiB shards, so a 27B merge needs a few GiB
+  of RAM, not the model twice. Plain linear LoRA only: embedding LoRA, trained biases, DoRA, saved
+  modules, convolution LoRA, a rank other than the config's, and a missing target are refused before
+  anything is written. The adapter's tokeniser/template replace the base's where shipped.
+- The recipe comes from the image (`/opt/radiance/share/radiance/recipes`) or the installed
+  `rad-convert`'s share; `auto` matches the base model's name in recipe headers and asks when several
+  fit. A recipe needing calibration is listed but never picked by `auto` — a finetune's Hessians are
+  not the stock model's.
+- It runs `rad-convert` on the CPU, under Docker as the caller with no network, and writes the log to
+  `OUT.log`.
+- `~/.config/rad-export/config.json` pins what auto cannot know: `image`, `out_dir`,
+  `recipes{model:recipe}`, `drafts{recipe:dir}`, `bases{repo:dir}`.
+- It is Python 3 with no dependencies; merging needs `torch`/`safetensors`, fetching a missing base or
+  drafter needs `huggingface_hub`. The image carries no Python; extract the script with
+  `docker run --rm --entrypoint busybox stilldeadcode/radiance cat /opt/radiance/bin/rad-export`.
+
+## Scoring a container (the KL mode)
+
+```sh
+# once, on the bf16 container
+radiance --model bf16.rad --kld-record /srv/kld/q38 --kld-corpus corpus.jsonl
+# each candidate, same flags otherwise
+radiance --model quant.rad --kld-ref /srv/kld/q38 --kld-out report.json
+```
+
+- The corpus is JSONL, one `{"prompt", "score_from"?, "source"?}` a line; only `prompt` is required.
+  Positions `[score_from, n-1)` are scored; `source` groups the report. Keep the scoring corpus
+  disjoint from the calibration corpus.
+- `--kld-record` writes the reference's log-probabilities (f16 over the vocabulary, the 16 most
+  likely tokens exactly, the token ids). DIR is never overwritten and is read only once `kld.json`
+  exists, which is written last.
+- `--kld-ref` scores this model's f32 logits against stored rows: mean, median, 99/99.9/99.99th
+  percentile KL, top-1 agreement, and both models' perplexity. `--kld-out` writes the report; `FILE.rows`
+  is `[positions, 4]` f32 (KL, both NLLs, argmax agreement) for position-by-position comparison.
+- The mode turns speculation and the prefix cache off, turns the step pipeline off, and refuses an
+  explicit spec depth above 0. The logits buffer holds a row per token of a step, so a large
+  `--max-num-batched-tokens` costs pinned host memory as well as VRAM.
+- `--kld-lora NAME` scores every document through a served adapter, against a reference recorded
+  from the merged checkpoint; `--kld-lora-sources PREFIX` runs only matching documents through it,
+  the rest as the base, in the same steps — each document's rows should be byte-identical to the
+  all-adapter and all-base runs.
+
+The gate the fleet uses (mean KL ≤ 0.03, top-1 ≥ 95 %) is on [[frank-archon]] and
+[[Quantization Production]]; the mode here is only the instrument.
+
+## Convert laws paid for in full
+
+- **`--plan-only` first.** A plan that resolves every op will boot; it costs seconds against an hour
+  of I/O on a large checkpoint.
+- **Declare runs at the step and context bounds, and some graphs depend on them.** Qwen4-Exp sizes
+  its QSA buffers by `--max-ctx` and refuses a `--max-tok`/context pair whose score plane would pass
+  2 GiB; the defaults (8192 tokens, the checkpoint's training context) fit most models, and a
+  generator's largest pass may override `--max-tok`.
+- **Scale names follow the tensor.** `scale_name()` appends `_scale_inv` to the *tensor* name, so a
+  stacked `…experts.gate_up_proj` keeps its scales at `…gate_up_proj_scale_inv`.
+- **File shadowing: first wins.** The reader opens index-named files sorted and emplaces every tensor
+  each file physically holds, first-wins. A merged PLE shard must sort first
+  (`00-ple.merged.safetensors`) or a raw shard wins the name.
+- **Never write through a staging symlink.** A checkpoint may symlink its raw index; `open(path,"w")`
+  writes through it and corrupts the checkpoint. Write a temp file and `os.replace`.
+- **One encoding per expert table.** A whole expert kept bf16 is the only thing legal beside a
+  table; a split tier (down=fp8, gate_up=w4) is unservable.
+- **The descriptor pair has no fallback** (above), and **convert is card-less**: GPTQ solves on CPU
+  BLAS, so the GPU is irrelevant to production and the card only decides what can be decoded.

+# Radiance Engine — shape, plugin model, container
+
+Radiance is StillDeadcode's inference server for AMD GPUs, written in C++20 and HIP: language
+models, plus image, video, speech and music generation and embeddings. One HTTP front end speaks
+OpenAI's chat, completions, Responses, images, audio and video APIs, Anthropic's Messages API and
+llama-server's native one. Nothing in the serving path is Python.
+
+The fleet's only radiance endpoint is [[frank-archon]] (2× R9700, TP=2, Dankserver). **This page
+and its siblings own the engine reference; the live deployment shape, its Eras and its measured
+laws stay on the endpoint page.** The numbers here describe upstream `main` as read 2026-10-30
+(release 1.14.0, plugin ABI 31). The fleet pin is older (1.8.1): a flag below that post-dates the pin
+is a boot refusal, never a silent no-op, and the endpoint page records the CLI families that pin
+itself retired relative to its own rollback target.
+
+Source: `https://codeberg.org/StillDeadcode/radiance` at `8da043c`. Engine docs live in `docs/`
+(`GUIDE.md` for serving, `TOOLS.md` for tools, `PLUGIN.md` for plugins, `ARCHITECTURES.md` per
+family, `OPS.md` for the op vocabulary, `spec.md` for the design).

+## The four moving parts

+    P2[architecture .so<br/>one per arch id × quant descriptor] --> C
+    P3[quantiser .so<br/>libquant] -->|rad-convert| A
+```
+
+- **Engine** — `core/`: declare phase, placement/memory planner, scheduler, KV manager, sampler,
+  tokeniser, HTTP server, media preprocessing.
+- **Kernel libraries** — implement ops for hardware. `libr4d` targets RDNA4 (`gfx1200`,
+  `gfx1201`); `libavx` serves the host backend (AVX-512/AVX2) with no GPU at all; `libref` is the
+  slow reference implementation every other library is checked against.
+- **Architecture plugins** — declare one model family at one weight format: its weights, buffers,
+  KV groups and the ops it issues each step. The engine picks one by an **exact (architecture id,
+  quantisation descriptor) pair, with no fallback**.
+- **Quantiser plugins** — `libquant`'s `rtn`, `gptq`, `awq`, `autoround`, `paroquant`, `m2xfp4`,
+  `ggml`, `cast`, `import`; they write a weight's numbers into an encoding's planes.
+- **Tools** — `rad-info`, `rad-convert`, `rad-export`, `rad-kbench`, `rad-tune`, `rad-schemas`,
+  `rad-tokcheck`, plus `rad-chatparse`, `rad-avx-check`, `r4d_selftest` in the build tree.
+
+## Two phases, one static graph
+
+`rad_arch_declare` runs once per rank and names every weight, buffer, KV group and op, in order.
+The core resolves every op against the kernel hierarchy per band, per domain, and completes the
+whole plan before a byte of weights is read. `rad_arch_step` then only *issues* handles obtained at
+declare; it may not allocate and may not synchronise. A model whose declare succeeds is fully known
+statically, which is what makes `--debug-graph`, the buffer liveness plan and `rad-convert`'s
+plan-only check possible.
+
+Consequences a plugin author must respect:
+
+- An op that never resolves is `RAD_NULL_HANDLE` and only fails if issued. A fusion is a *selection*:
+  ask for the fused op, emit the chain when `rad_op_resolved` is false.
+- Declaration order is the buffer planner's liveness. A drafter must be declared after the trunk
+  it runs behind, or trunk and drafter buffers silently share bytes.
+- Every op in the graph must have a row in a loaded kernel library. `libref` implements the
+  conventional vocabulary in `docs/OPS.md`; device-only ops (most fusions) exist only in `libr4d`.
+
+## The `.rad` container (RAD2)
+
+A container is one file holding everything the server needs: weights as **canonical encoding
+planes**, the tokeniser (and optionally a second vocab), the chat template, metadata, the recipe it
+was made with, and any draft head. It names no kernel library.
+
+- Planes are kernel-independent: codes, scales, zero points, codebooks — row-major, bit-packed
+  sub-byte where needed. A kernel rearranges them into its own layout at load (`layout`/`relayout`
+  hooks), losslessly, so a kernel library can change layouts without reconverting the model.
+- Encodings are data, not an enum: `RadEncoding` names the scheme (`plain`, `affine`, or a
+  quantiser's own), the planes by role, the scale grouping, and a transform (`fwhtN`, `perm`,
+  `givens`). That is how one file can hold block-FP8, int4, MXFP4, NVFP4-imported, ParoQuant
+  rotations and llama.cpp grids.
+- `rad-info` is the reader: sections (strings, metadata, directory, planes, encodings, vocab,
+  profile, data), `--meta`, `--vocab`, `--recipe`, `--plugins`, and `-v` for every tensor with its
+  encoding and what made it.
+
+See [[Radiance Conversion]] for producing one and [[Radiance Tools]] for inspecting it.
+
+## Selection key and version law
+
+- A checkpoint's architecture id is its `config.json` `model_type` without underscores; `rad-convert
+  --arch ID` overrides it. `rad_arch_quant` supplies the quantisation descriptor (empty for an
+  unquantised checkpoint).
+- **No fallback.** A raw official FP8 checkpoint whose `quantization_config.quant_method` is `fp8`
+  is not the pair the `qwen4exp_fp8` plugin claims (`(qwen4exp, "")`), so both serve and convert
+  refuse it until the descriptor is changed with `--set` or a staged `config.json`. The deployment
+  lesson is on [[frank-archon]]; the mechanism is on [[Radiance Conversion]].
+- `RAD_ABI_VERSION` covers every header a plugin compiles against. A plugin reporting a different
+  number is refused at load, with both numbers printed. It moves on any shape change, not on a new
+  optional export; rebuild when it changes. Release version and ABI are independent: `/version`
+  reports the release, `rad-info --plugins` reports what loaded.
+

+| `RADIANCE_KERNELS` | default for `--kernels`: ordered kernel libraries, first wins; unnamed libraries are not loaded |
+| `RADIANCE_TUNE` | pin a kernel's tuned axes for a measurement (a measurement aid, not a deployment setting) |
+| `RADIANCE_CALIB_DIR` | a serve run records per-layer input Gram matrices here (the GPTQ calibration tap) |
+| `RADIANCE_CALIB_TOKENS` | tokens after which the tap stops and writes (default 65536) |

+| `RADIANCE_DEBUG_RESID` | residual-stream probe per (layer, site) |
+| `RADIANCE_DFLASH_Q_TEMP` | temperature of a DFlash2 coupled walk's candidate softmax |
+
+The full list of debug knobs (`RADIANCE_DEBUG_*`, `RADIANCE_DUMP_*`, `RADIANCE_OP_ORACLE`, …) is in

+# Radiance HTTP API
+
+One server serves one model. It answers OpenAI's chat/completions/Responses/images/audio/video APIs,
+Anthropic's Messages API and llama-server's native one, so their clients and SDKs work unchanged.
+`model` in a request is accepted and **not enforced**.
+
+## Endpoints
+
+| route | what it serves |
+|---|---|
+| `POST /v1/chat/completions` | chat: tools, reasoning, streaming, grammars |
+| `POST /v1/completions` | raw text completion |
+| `POST /v1/embeddings` | an embedding head, else 501 |
+| `POST /v1/images/generations`, `/v1/images/edits` | OpenAI images API; needs an image model, else 501 |
+| `POST /v1/systemone` | LiquidAI d1 decisions: named yes/no, choice and score questions as probabilities; needs a d1 container, else 501 |
+| `POST /v1/audio/transcriptions` | OpenAI speech-to-text; needs a transcribing plugin, else 501 |
+| `GET /v1/realtime` (WebSocket) | streaming transcription session |
+| `POST /v1/audio/speech` | speech (Breeze-TTS-2, drama-3) or a song (MiniMax-Music3), whole or streamed |
+| `GET /v1/audio/speech/stream` (WebSocket) | text streamed in, each sentence's audio out |
+| `POST /v1/videos`; `GET /v1/videos[/:id[/content]]`; `DELETE /v1/videos/:id` | video jobs made in the background, downloaded as MP4 |
+| `POST /v1/messages`, `/v1/messages/count_tokens` | Anthropic Messages, for Claude Code and the Anthropic SDKs |
+| `POST /v1/responses`, `/v1/responses/input_tokens` | OpenAI Responses, for Codex and SDK clients |
+| `POST /completion`, `/completions`, `/infill` | llama-server native completion and fill-in-the-middle |
+| `GET /v1/models`, `/v1/models/:id` | what is loaded, with `max_model_len`, `root`, `capabilities` |
+| `GET /health`, `/v1/health`, `/ping`, `POST /ping` | liveness |
+| `GET /load`, `/version`, `/props`, `/server_info`, `/diagnostics` | load; release version; llama-server props; full configuration; the startup report as JSON (`/diagnostics` is same-machine-only without an API key) |
+| `POST /apply-template`, `/v1/chat/completions/input_tokens` | the rendered prompt; its token count |
+| `GET /metrics` | Prometheus |
+| `POST /tokenize`, `/detokenize`; `GET /get_tokenizer_info` | vLLM's shape and llama-server's at once |
+| `POST /reset_prefix_cache`; `DELETE /sessions/<label>`, `/sessions?id=<id>` | drop every cached prefix; forget a stored conversation |
+| `GET /`, `/dashboard`; `GET /stats`, `/graph`, `/sessions` | the dashboard and the JSON it is drawn from |
+
+Unversioned shorthands exist for chat, chat input tokens, embeddings, images, audio transcriptions,
+audio speech, models, responses and completions, for a client given the bare host as base URL.
+`/completions` **without** `/v1` is llama-server's native completion. A path nothing serves is a JSON
+404.
+
+A text prompt to `/v1/completions`, `/v1/embeddings` or `/tokenize` reads control tokens as tokens
+(as vLLM and llama.cpp do), so a client rendering its own template can send `<|im_start|>user\n…`.
+The model's declared BOS is prepended unless the prompt already opens with it.
+
+## Chat
+
+```sh
+curl -s localhost:8000/v1/chat/completions -H 'Content-Type: application/json' \
+  -d '{"model":"m","messages":[{"role":"user","content":"hi"}],"max_tokens":200,"temperature":0.7}'
+```
+
+- **No chat template → 501** on this route (the container carries one; `--override-chat-template`
+  replaces it). Use `/v1/completions` instead.
+- Thinking off has three spellings: `chat_template_kwargs.enable_thinking=false`,
+  top-level `enable_thinking=false`, or `reasoning_effort:"none"`.
+- Reasoning returns in `choices[].message.reasoning_content`, separate from `content`.
+  **Reasoning counts against `max_tokens`**; a reply that runs out inside it has empty `content` and
+  `finish_reason:"length"`. `usage.completion_tokens_details.reasoning_tokens` tells that case from a
+  model that answered nothing.
+- `thinking_token_budget` (aliases `thinking_budget`, `thinking_budget_tokens`,
+  `reasoning_budget_tokens`) closes the reasoning block at N tokens and forces the close, so it holds
+  under speculation and at any temperature. It needs a one-token end marker; otherwise the response
+  has no `completion_tokens_details` and a budget is a 400.
+- `continue_final_message` continues a conversation ending in an assistant message instead of
+  answering it; `add_generation_prompt` opens a new turn.
+- Tool calls: `tools`, `tool_choice` (`auto`, `none`, `required`, named function),
+  `parallel_tool_calls`. `required`/named hold the whole reply to calls after the reasoning block and
+  cannot combine with `response_format` or `grammar`.
+- Structured output: `response_format` (`json_object` or `json_schema`), llama-server's `json_schema`
+  shorthand, or a raw GBNF `grammar`. A chat template that drops the grammar makes the request a
+  refusal.
+
+## Streaming
+
+```sh
+curl -N localhost:8000/v1/chat/completions -H 'Content-Type: application/json' \
+  -d '{"model":"m","messages":[{"role":"user","content":"Count to ten."}],
+       "max_tokens":100,"stream":true,"stream_options":{"include_usage":true}}'
+```
+
+Server-sent events in OpenAI's delta format, terminated by `data: [DONE]`. **Nothing is sent while
+the prompt is read**: the first event (the `role: assistant` chunk) goes out with the first generated
+token, so a client timing its first event measures time-to-first-token. `return_progress` adds
+llama-server's `prompt_progress` chunks during prefill; `timings_per_token` adds `timings` to every
+chunk.
+
+## Completions, embeddings, images, audio, video, tokens
+
+- **Completions** — `/v1/completions` takes `prompt` (string or token ids), `echo`, `logprobs`,
+  `preserved_tokens`. `/completion` is llama-server's native route; `/infill` is fill-in-the-middle.
+- **Embeddings** — `input` is text, a batch, or token ids; `encoding_format` `float`/`base64`;
+  `dimensions` truncates to the first N and renormalises; `prompt_name` prepends the model's named
+  prompt. Pooling is the model's; the engine does not renormalise.
+- **Images** — `/v1/images/generations` returns `b64_json`; `size` defaults to 2048×2048. Edits take
+  one picture or up to ten (`image[]`), multipart as OpenAI's SDKs send them, with an optional mask
+  (repaint only where transparent). `partial_images` streams previews as SSE.
+- **Speech to text** — `/v1/audio/transcriptions`; `/v1/realtime` streams audio in and words back as
+  they are spoken. The model's prompt shape comes from its plugin's audio format, not from the server.
+- **Speech and music** — `/v1/audio/speech` (whole or streamed) with `instructions` describing a voice
+  (Breeze-TTS-2) or speakers written in the input (`<|speaker:1|>`, `[laughs]` for drama-3); a music
+  model takes the lyrics as `input` and the description as `instructions`. `/v1/audio/speech/stream`
+  streams text in and audio out as each sentence completes.
+- **Video** — `/v1/videos` is a job: a video with its stereo soundtrack from a prompt, 5–14 s, up to
+  1344×768, made in the background; `GET /v1/videos/:id/content` downloads the MP4.
+- **Tokenising** — `POST /tokenize` accepts vLLM's shape (`prompt` or `messages` in, `prompt` out) and
+  llama-server's (`content` in/out, `with_pieces`). `POST /detokenize` reverses it.
+  `GET /get_tokenizer_info` reports the tokeniser configuration.
+
+## Request fields
+
+Accepted fields, in OpenAI's, vLLM's and llama-server's spellings:
+
+| field | notes |
+|---|---|
+| `model` | accepted, not enforced |
+| `messages` / `prompt` / `input` | chat / completion / embedding |
+| `max_tokens`, `max_completion_tokens`, `n_predict` | default is what the context leaves; `-1` is llama-server's "no limit"; clamped to context and to `--max-tokens-cap` |
+| `temperature`, `top_p`, `top_k`, `min_p`, `typical_p` | sampler |
+| `presence_penalty`, `frequency_penalty`, `repetition_penalty`/`repeat_penalty`, `repeat_last_n` | penalties |
+| `xtc_probability`, `xtc_threshold`, `dry_*` | XTC and DRY |
+| `seed` | absent means "pick one", not 0 |
+| `n` | 1..`--max-n`; prefix cache makes the fan-out nearly free after the first |
+| `stop` | string or array, bounded by `--max-stop-strings`/`--max-stop-bytes` |
+| `priority` | scheduler hint |
+| `ignore_eos` | generate to `max_tokens` whatever the model emits |
+| `stream`, `stream_options.include_usage`, `timings_per_token`, `return_progress` | streaming controls |
+| `samplers` | llama-server's order; this engine's chain is penalties, DRY, top-k, top-p, min-p, typical, XTC, with temperature first or last; any other list is refused by name |
+| `session_id` | labels the conversation on `/sessions`, dashboard and `DELETE` |
+| `control_vector` | `true` applies the deployment's vector to this request; absent takes the deployment default; a deployment with no vector refuses `true` |
+| `logprobs`, `top_logprobs`, `n_probs` | up to 20 alternatives; not with `echo` |
+| `tools`, `tool_choice`, `parallel_tool_calls`, legacy `functions`/`function_call` | chat only |
+| `add_generation_prompt`, `chat_template_kwargs`, `continue_final_message` | chat only |
+| `reasoning_format`, `reasoning_effort`, `enable_thinking`, `thinking_token_budget`, `preserve_thinking` | chat only; levels are the template's (`capabilities.reasoning_efforts`); `none`/`minimal` turn thinking off |
+| `response_format`, `json_schema`, `grammar` | structured output; `grammar` and `response_format` are mutually exclusive |
+| `echo`, `preserved_tokens` | `/v1/completions` only |
+| `encoding_format`, `dimensions`, `prompt_name`, `image_tokens` | `/v1/embeddings` only |
+| `images_config` | image models only: a named processor mode or an object restating served sizes |
+
+## What is refused, ignored, and clamped
+
+The contract: **a 200 means every field that could change the answer was honoured.** Fields fall
+into four classes.
+
+- **Inert** — accepted and ignored because they cannot change the answer: OpenAI/OpenRouter
+  bookkeeping (`user`, `metadata`, `store`, `service_tier`, `prompt_cache_key`, …) and llama-server's
+  own speed/slot knobs (`cache_prompt`, `id_slot`, `n_cache_reuse`, `backend_sampling`,
+  `speculative.*`, …). The prefix cache and speculation here are the server's and never change output.
+- **Guarded** — known, unimplemented, and able to change the answer: accepted at their off value,
+  refused by name otherwise. `logit_bias` (empty), `mirostat` (0), `top_n_sigma` (≤0),
+  `dynatemp_range` (≤0), `min_keep` (0), `post_sampling_probs` (false), `best_of` (≤1), `suffix`
+  (empty), `lora` (empty — an adapter is chosen by `model`), `modalities`/`audio` (`["text"]`/null),
+  `n_indent` (0), `t_max_predict_ms` (≤0), `return_tokens` (false), `grammar_lazy`,
+  `grammar_triggers`, `preserved_tokens` (empty on chat).
+- **Ignored** — anything else unknown, logged at debug. An unknown field is far more often a client's
+  extension than a misunderstood request.
+- **`max_tokens` is the exception**: if prompt + `max_tokens` exceeds the context, it is **clamped**
+  and served, ending `finish_reason:"length"`, because refusing would produce no tokens instead of
+  fewer. A prompt that does not fit on its own is a 400 `context_length_exceeded` naming
+  `n_prompt_tokens`, `n_ctx`, and how many tokens must go.
+
+## Anthropic, Responses, llama-server
+
+- `/v1/messages` is translated into a chat request, so chat defaults, refusals and limits apply.
+  Streamed (`message_start`, content blocks, `message_delta`, `message_stop`) or not:
+  `ANTHROPIC_BASE_URL=http://host:8000 ANTHROPIC_API_KEY=$KEY claude` works. `/v1/messages/count_tokens`
+  returns the prompt length.
+- `/v1/responses` maps `instructions`/`input` (strings, messages, `function_call`,
+  `function_call_output`, `reasoning` items) into the chat request; `max_output_tokens`,
+  `reasoning.effort`, `text.format` map to chat fields; undefined fields pass through. The event stream
+  carries `output_index`, `content_index`, `sequence_number`, and opens with `response.created` and
+  `response.in_progress`. A reply cut at `max_output_tokens` is `incomplete`. Function tools a
+  `namespace` groups are named `<namespace>__<name>`; built-in tools and freeform custom tools are
+  left out.
+- `/completion`, `/completions`, `/infill` are llama-server's own shapes, for llama.vim/llama.vscode.
+
+## Auth, CORS, errors
+
+- `--api-key KEY` requires `Authorization: Bearer KEY` or `X-Api-Key: KEY` on every request except
+  `/health`, `/v1/health`, `/ping` and the dashboard page. An empty key is refused at startup.
+- CORS headers are sent unless `--no-cors`.
+- Errors are JSON. Over-context is 400 `context_length_exceeded`; a full queue is 429 with
+  `Retry-After`; a capability the model lacks is 501; a guarded field is 400 naming the field and its
+  accepted off value.

+# Radiance model families
+
+The selection key is the exact **(architecture id, quantisation descriptor)** pair, so a family at
+two weight formats is two `.so` files. A checkpoint's id is its `config.json` `model_type` without
+underscores (`qwen3_5` → `qwen35`); `rad-convert --arch ID` overrides it. `data/recipes/` is the
+authority: **read the recipe's header** — it names the exact `rad-convert` line, its `--set` keys
+and whether it needs calibration.

+
+A checkpoint served at its own precision needs no container at all:
+`radiance --model /srv/models/hf/Qwen/Qwen3.8-27B-FP8`. Convert when you want a tier only a container
+has (quantised encodings, a drafter, a second vocab) or a smaller file.
+
+## Family-specific traps
+
+- **`head_dim` is read, never derived.** On the Qwen hybrids it is 256 while `hidden_size /
+  num_attention_heads` is 213; a derived value silently breaks projection widths, KV page size and the
+  attention kernel's band.
+- **A fused projection shards by part, not by contiguous rows.** A tensor-parallel rank owns a slice
+  of *each* stacked projection in a fused `[gate|up]` or `[q|k|v|z]`; a contiguous slice would hand
+  rank 0 the whole gate, and the model would produce fluent wrong text. This is declared through
+  `RadWeightDecl::row_parts`, never inferred from the container.
+- **Gemma 4 26B-A4B:** the routed experts' `gate_up` may be block fp8, but `down` stays bf16 unless the
+  experts were padded to 768 — hence the `-pad768` recipe.
+- **GLM-5.3-Flash:** every weight is served as stored except the latent attention's small `kv_b`,
+  decoded to bf16. Its KV cache is bf16 only (the plugin refuses `fp8` at startup), and at 172 GiB it
+  needs `--tp 8`.
+- **TranslateGemma 27B:** the checkpoint's template takes structured turns naming two languages and
+  refuses the plain turn the server renders at startup. The container therefore serves a plain Gemma 3
+  template, and a client sends on `/v1/completions` the prompt the checkpoint's own template renders.
+- **ParoQuant containers made before 1.5.0 are refused at startup.** Convert again with the old
+  container as `--reuse`; every tensor that did not change is copied.
+- **SDXL carries no tokeniser.** Pass CLIP's `tokenizer.json` beside the single file. A Krea 2
+  finetune shipped as one DiT file in Krea's key names is rewritten into a directory whose
+  `transformer/` holds it (`scripts/krea2_native.py`), with the release's other parts copied in.
+- **Anima** ships as three single files: `--add` the text encoder and VAE, `--config` a Qwen3-0.6B-Base
+  directory (config + tokenizer), `--tokenizer2` ComfyUI's T5 tokenizer, `--arch anima`,
+  `--set anima.variant=…`.
+- **drama-3's codec is `codec.pth`**, a `torch.save` file read as data, never unpickled.
+- **Generators that load LoRA files declare their module aliases**; the checkpoint and a ComfyUI port
+  disagree in ways that load without error and generate garbage. The per-plugin alias table is in
+  `docs/ARCHITECTURES.md` ("Adapter key names of the generators").
+- **Licences travel with the checkpoint, not the engine.** Qwen-Image 2.1 is non-commercial;
+  MiniMax-H3's licence excludes the EU, UK, Republic of Korea and USA; drama-3's community licence
+  needs a commercial licence to serve speech to others, and cloning a real person needs consent;
+  Breeze-TTS-2 is research/non-commercial.

+# Radiance operations
+
+This is the engine-level runbook. The fleet's deployed shape, its unit and its deploy path live on
+[[frank-archon]]; the flags themselves on [[Radiance Serve Options]].
+
+## Install
+
+```sh
+git clone https://codeberg.org/StillDeadcode/radiance.git && cd radiance
+./build.sh                                   # configure, build for the cards present, run fast tests
+./build.sh --no-hip                          # host backend only
+cmake -S . -B build -G Ninja -DRAD_GPU_TARGETS='gfx1201'   # cards this machine lacks
+cmake --install build                        # after -DCMAKE_INSTALL_PREFIX=/opt/radiance at first configure
+```
+
+Needs Linux, git, a C++20 compiler, CMake 3.21+, Ninja; for device kernels ROCm 10.1 or 7.2
+(`hipcc`, `ROCM_PATH` if not `/opt/rocm`).
+
+- **Name the prefix at the first configure.** The default plugin path `<prefix>/share/radiance` is
+  compiled in from that configure; `cmake --install build --prefix DIR` alone gives a tree that looks
+  for its plugins elsewhere.
+- The prefix gets `bin/`, `include/radiance/`, `lib/cmake/radiance/`, `libexec/radiance/`,
+  `share/radiance/` (plugins and recipes) and `share/doc/radiance/`.
+- With ROCm 10.1 the build turns VOPD pairing off because its LLVM 24 pairs in heap-address order, so
+  two builds of one source can differ. The Docker image's compiler has the fix and keeps pairing
+  (faster fp8 prefill GEMMs); declare such a compiler with `-DRAD_HIP_VOPD_REPEATABLE=ON`. ROCm 7.2 is
+  unaffected.
+
+Run without Docker:
+
+```sh
+export RADIANCE_HOME=$PWD/build/radiance_home   # plugins; an install finds its own
+build/bin/radiance --model /srv/models/rad/minicpm5-2b-fp8.rad --port 8000 <flags>
+build/bin/radiance --model StillDeadcode/minicpm5-2b-fp8 --port 8000 <flags>
+```
+
+`--model` also takes a repo id: the server runs `scripts/hfget.sh` into `--download-dir`, serves the
+one `.rad` at the repo's top level, or the directory as a checkpoint when it holds none. A repo with
+several containers is refused, naming them. Every start checks the hub; a start that cannot reach it
+serves the copy a complete earlier fetch left, and a transfer that fails part-way stops startup.
+
+## Container
+
+The published image is `stilldeadcode/radiance`, kernels built for `gfx1201`. The host needs Docker
+and an `amdgpu` driver supporting ROCm 10.1 — **not** ROCm itself.
+
+```sh
+docker run -d --name radiance --network host --init --ulimit memlock=-1 \
+    --device /dev/kfd --device /dev/dri --security-opt seccomp=unconfined \
+    --group-add "$(getent group render | cut -d: -f3)" \
+    --group-add "$(getent group video | cut -d: -f3)" \
+    -v /srv/models/rad:/models:ro \
+    radiance --model /models/m.rad --tp 2 --host :: --port 8000
+```
+
+Each option is load-bearing:
+
+| option | why |
+|---|---|
+| `--device /dev/kfd --device /dev/dri`, `render`/`video` groups | the cards |
+| `--security-opt seccomp=unconfined` | Docker's default profile refuses io_uring (a disk-tier n-gram table's reads) and the NUMA calls the ROCm runtime makes for host memory |
+| `--init` | an init process as PID 1 forwards SIGTERM; the engine finishes its step and releases the cards |
+| `--ulimit memlock=-1` | a host-side pinned n-gram copy can be tens of GiB, far past Docker's default |
+| `--network host` | the server binds the host's addresses directly, IPv4 and IPv6, no NAT |
+
+The image is `FROM scratch` around the stripped install tree: busybox as the only shell, plus `curl`,
+`jq` and a CA bundle for `hfget.sh`; **no Python, no package manager**. Tools (`rad-convert`,
+`rad-info`, `rad-kbench`, `rad-tune`, `rad-schemas`, `rad-tokcheck`) are on `PATH`; recipes are in
+`/opt/radiance/share/radiance/recipes/`. Its entrypoint is `radiance`. It sets
+`GPU_MAX_ALLOC_PERCENT=100` and `GPU_MAX_HEAP_SIZE=100` because the HIP runtime's defaults cap one
+allocation and the heap below what the placement plan hands out.
+
+Build your own with `docker/build.sh` (`-t 'gfx1200;gfx1201'` for targets, `-j` compile jobs, `-E`
+to skip tests, `-s host` to build remotely). The context is `git archive` of the commit, so the image
+holds only committed content. The `rootfs` stage fails the build if any ELF cannot be resolved inside
+a chroot of the tree.
+
+Compose: one file per model plus `common.yaml`, copied to the serving host with an `.env` setting the
+image, models directory (mounted read-only at `/models`), API key, port, user and GPU groups. Every
+model listens on the same port, and most use both cards, so **run one at a time**. The models
+directory must be on a local filesystem that does direct I/O (ext4, XFS, btrfs); on btrfs with
+compression, a container copied into a `chattr +C` directory is stored uncompressed and direct reads
+work.
+
+A plugin of your own is mounted and put first on the search path; nothing in the image changes:
+
+```sh
+-v /srv/radiance-plugins:/plugins:ro -e RADIANCE_HOME=/plugins:/opt/radiance/share/radiance
+```
+
+## Host prerequisites (upstream's two-R9700 checklist)
+
+| item | setting |
+|---|---|
+| firmware | Above 4G Decoding on (Resizable BAR needs it); CSM off (pure UEFI) |
+| kernel command line | `iommu=pt amdgpu.ppfeaturemask=0xfff7ffff amdgpu.ras_enable=0` |
+| power/clock | OverDrive bit needed for `ppfeaturemask`; apply a power cap only while no process holds `/dev/kfd` |
+| memlock | `--ulimit memlock=-1` (container) / `LimitMEMLOCK=infinity` (systemd) when host memory is pinned |
+| two engines, one tmpfs table | `amdgpu.no_system_mem_limit=1`, or the second pin can be refused |
+| storage | a local fs with O_DIRECT for the container; a tmpfs sized for the table for `--ngram-placement ram=DIR` |
+
+Why each: `iommu=pt` keeps DMA identity so the cards can reach each other's memory and pinned host
+pages; `ppfeaturemask` enables the power controls; `ras_enable=0` turns VRAM ECC off (ECC reserves
+about 2 GiB a card). Verify peer access with a rate in `lspci`/the card tables — a missing cell means
+no peer access; check `iommu=pt` and the BAR size. The fleet's own boot-line law for Dankclaw
+(`iommu=pt`, tracked in the repo) is on [[dankclaw-iommu-translation-off]]; Dankserver's cards are a
+different box and its posture is on [[Dankserver System Specs]].
+
+## Readiness: the receipt, then `/health`
+
+Startup states every budget **before anything is allocated**, then loads. `/health` (and
+`/v1/health`, `/ping`) answers only once the load completes, so a bare health gate is honest. While it
+loads, expect 503 for minutes; do not restart over it. `--live` draws the live view (redirected, one
+`greppable key=value` line). `/diagnostics` returns the startup report as JSON — **same-machine-only
+without an API key** — with every option and its source and the hardware read again now.
+
+Read the receipt in this order:
+
+1. `elastic` — what the experts and KV cache share after non-expert weights.
+2. The split: `experts … / kv cache …`, and `unclaimed` if any.
+3. `kv: the pool backs N % of the worst case … M full-length sessions` — the referee for whether the
+   demand signal (`--max-model-len` × `--max-num-seqs`) is funded.
+4. `activation arena` and what each size lends; `prefill staging`; `hardware queues` and their VRAM.
+5. `host_pool` opened/used, `vram_weights`, the PLE or n-gram placement, the vision tower's placement.
+6. `device: the N cards reach each other's memory directly` or the failed pairs;
+   `expert prefetch on/off`; `chunk geometry`; `speculation:`; `chained launches`; `draft trees`.
+7. `card N settled at … free` — memory taken after the budget read comes out of headroom; a warning
+   names the `--gpu-headroom-mib` that clears it.
+
+A boot refusal prints the reason and exits nonzero; when it happens inside `podman run`, the
+container stops at once and the unit's restart policy re-runs the same refusal. A unit in
+`activating (auto-restart)` with a fast nonzero exit is therefore a **preflight/refusal or a boot
+refusal**, not an engine fault: read the journal line and the argv, not the GPU.
+
+## Lifecycle and restart
+
+- SIGTERM finishes the current step and releases the cards. In a container, `--init` forwards it;
+  `podman stop -t N`/`docker stop` is the graceful path.
+- A systemd unit should `exec podman wait` (or run in the foreground) so the script's lifetime is the
+  container's: a crash is a nonzero exit and the restart policy is real. Set `TimeoutStopSec` above
+  the stop grace, or systemd records `Failed with result timeout` on a healthy stop.
+- `Restart=always` rather than `on-failure` for a server whose front end can exit cleanly after a
+  worker fault.
+- Model load is slow (minutes cold). The deployer's LLM wait budget is on [[Deployment Flow]]; a
+  container restart loop during a legitimate load is worse than waiting.
+
+## Two engines on one set of cards
+
+- `ROCR_VISIBLE_DEVICES` picks each engine's cards explicitly.
+- `--weight-prefetch off`: a weight read beside a collective puts a queue switch into every decode
+  step when another server shares the cards.
+- `--ngram-placement ram=DIR`: two engines on separate card sets hold one table in host memory
+  (`DIR/ngram-<id>.tab` in a tmpfs, `MAP_SHARED`, pinned). The `<id>` hashes the container path, size,
+  mtime and the table's place, so a file never serves another model. The first engine fills it; a
+  second verifies samples and only pins it; the last to leave deletes it. The driver counts a shared
+  page against every process that pins it, so the pinned total is twice the table.
+- The engine prefers discrete cards (all of the first one's architecture), integrated only when
+  there is nothing else; on integrated graphics device memory is host memory and the budget leaves an
+  eighth of host RAM to the host.
+
+## Logs and diagnostics
+
+- `-v` / `-vv`; `RADIANCE_LOG` sets the level without a flag. `RADIANCE_LOG_STEPS=1` prints every
+  step's token count (how a chunk geometry is confirmed in practice).
+- The engine writes to stderr. Under a container, the journal holds only the container's own output;
+  a rootless `podman logs` covers only the current instance across recreations.
+- `/metrics` is Prometheus text: engine steps by kind and their seconds, decode/prefill rates,
+  prefill chunks held back, steps held by interleave, draft acceptance and depth, prompt-lookup
+  proposals held, KV bytes and the tokens they address, stream misses and bytes, prefix hits and
+  evictions, preemptions and queue depth. `/stats`,
+  `/graph`, `/sessions` back the dashboard. `scripts/statsdump.py` records `/stats` to JSONL with
+  time and gap, for a machine with no scraper (its key comes from `--api-key` or
+  `RADIANCE_API_KEY`).
+- `RADIANCE_PROFILE_EVERY`, `RADIANCE_DUMP_BUF`/`RADIANCE_DUMP_DIR`, `RADIANCE_OP_ORACLE`(+) and the
+  `RADIANCE_DEBUG_*` family are debug instruments; they are not deployment settings.
+
+## Verifying a deploy (fleet law)
+
+`deploy.sh` green is not proof of what is running. A leftover systemd drop-in or a stale container
+identity can serve a different model at a different shape while `/health` is 200. After deploying
+any recently-benched service:
+
+1. `systemctl show <svc> -p DropInPaths` — must be empty.
+2. `tr '\0' ' ' </proc/$(pidof radiance)/cmdline` (or the container's `Config.Cmd`) — the argv you
+   meant.
+3. The boot ledger — the shape you meant.
+4. A behavioural probe — `/v1/models` for the served id, one chat turn, one tool call, and a vision
+   probe with a solid colour and an exact expected word.
+
+`/v1/models` is an echo on some runtimes; on radiance it is authoritative for the alias, but the
+argv and the ledger are what prove the payload and shape. The three-pin revert discipline for a
+payload swap is on [[Model Swap and Rollback]]; the live deployment is [[frank-archon]].
+
+## Security posture
+
+- `--api-key` requires a bearer token or `X-Api-Key` on every route except `/health`, `/v1/health`,
+  `/ping` and the dashboard; the key is a command-line argument, so it is readable in
+  `/proc/<pid>/cmdline` by any local user of that host. On a single-tenant inference box the network
+  boundary is the real control; do not run one where untrusted local users share the host.
+- `/diagnostics` is same-machine-only without a key, because it prints the whole configuration.
+- `--security-opt seccomp=unconfined` is a genuine widening, required by io_uring and the ROCm
+  runtime's NUMA calls; it belongs on a dedicated model host, not a general-purpose one.
+- Mount model directories read-only; a container with `/models` writable adds nothing a serve needs.
+- A control vector can remove refusal behaviour. Loading one is a safety decision, not a
+  performance one; the flag is `--control-vector`, and `--control-vector disabled` is the default.
+
+## Failure signatures at startup
+
+| what you see | what it is |
+|---|---|
+| unknown/retired flag, or a flag refused by name | a boot refusal — the pin does not have it; change the trio, not the invocation |
+| "no plugin claims `<arch>` at `<quant>`; served at: …" | the (id, descriptor) pair has no plugin; fix the descriptor with `--set`/convert |
+| "reports ABI N, engine M" | rebuild the plugin against this engine |
+| budget refusal / `host_pool` short | the shape does not fit this card/host; lower demand or pin more host RAM |
+| `--ngram-placement ram` refuses | memlock short; raise it or use `auto`/`disk` |
+| `--kv-cache-dtype fp8_v4`/`k6_v4` refused, plugin named | no kernels for this geometry |
+| `--p2p on` refuses, pairs named | the driver has no peer access; use `auto`/`off` |
+| first launch of a never-run kernel faults | too little `--gpu-headroom-mib` for its code object |
+| unit loop, no container, no engine log | a preflight refusal (TTM/memlock/digest/model) re-run by `Restart=always` |
