chore(release): prepare 1.1.0 — version sync, changelog, front-page limitations

Version 1.1.0 in pyproject, the package, uv.lock and every README install
line; the "current tag" entry moves to v1.1.0 and v1.0.0 becomes history.
The CHANGELOG states what a user notices: BM25 ranking on passages and
titles, sub-questions in one call, a map per bundle, a weak-coverage
signal, one generic skill plus the server as the standard way in over a
folder, --gate in okf project, and okf-consumption/2 as BREAKING for a
reader of withheld. Known limitations gain the vocabulary route through
the map, the retrieval gate's red rows as they stand under BM25, the
answer smoke test (no corpus content, no counts) and unmeasured speed.

eval/svar/ is ignored the way eval/soek's sets are: answers about a
consumer's corpus are inputs, never committed. No tag, no push.

+## [1.1.0] — 2026-09-21
+
+The reading side. Nothing here changes how a bundle is built from a folder;
+what changes is how a question finds its way into one, and how many bundles
+one question can reach.
+
+### Changed
+
+- **A new default ranking: BM25 over passages and titles.** A concept is scored
+  on its best 500-character passage and on a title/path-weighted field, and the
+  two are fused by rank. A concept longer than 4 000 characters is delivered as
+  its answering passage, with `passage: {start, end, of}` saying where in the
+  concept it sits. The previous fusion stays reachable as `--ranking fusion`.
+  A reader will see different excerpts, in a different order, for the same
+  question on the same bundle.
+- **BREAKING for anyone who reads the payload: the contract is
+  `okf-consumption/2`.** `withheld` is no longer a list with one entry per
+  concept left out; it is a mapping with `total`, `by_rule`, `nearest` (the
+  best-ranked drops by name, title and source document, 20 by default) and
+  `complete`. Measured on a large real bundle, the old list was about two
+  thirds of the written payload and none of it counted against the budget the
+  payload reported. `--withheld-full` brings the whole list back. The revision
+  was bumped so that code indexing `withheld` as a list fails loudly instead of
+  reading the wrong thing. `--withheld-titles` is retired.
+- **The server and the generic skill are the standard way in, over a whole
+  folder.** `okf project` and the front page say it in that order: register
+  `okf mcp --root` once, on user scope, and every project can ask every bundle
+  under it; the skill beside a bundle is the supplement for someone who would
+  rather register nothing. Neither is made again when a bundle is rebuilt.
+- **`okf skill` writes ONE generic skill by default**, carrying a working
+  method and an answer form and no bundle's numbers, so it does not go stale
+  when a bundle is rebuilt. `--for-bundle` keeps the per-bundle form.
+  `okf project` puts it at `.claude/skills/okf-consume-any/`.
+
+### Added
+
+- **Several sub-questions in one call.** `okf consume --question A --question
+  B` (and `questions` on the server's `okf_ask`) reads the bundle once, cuts
+  each sub-question as if asked alone and interleaves the deliveries under the
+  same `k` and byte limit. One question gives exactly the payload it gave
+  before.
+- **A map per bundle.** `okf card` and the server's `okf_describe` carry
+  `map`: one line per source document with its concept titles in document
+  order, a numbered series folded into one line. The working method is to read
+  the map first and ask two to four sub-questions in the map's own words.
+- **A signal for weak coverage.** The payload's `coverage` carries
+  `absent_terms` (question words the bundle holds in no form) and `weak` (one
+  such word, or nothing delivered). It is a reading, not a verdict.
+- **A folder of bundles in one command.** `okf card <folder>` shows every
+  bundle under it, `okf consume <folder>` asks every bundle in one call
+  (`--bundle-id` narrows it to one), and `okf check` reads that reply, holding
+  each payload to all 19 rules on its own. These are the same functions the
+  server runs.
+- **A table fragment is read under its heading.** A concept carrying the
+  proposer's mechanical table title is ranked and shown under the nearest
+  concept above it in its document; the excerpt keeps `own_title`. No bundle
+  byte moves.
+- **`okf project --gate`**: the gate can be chosen when building a project,
+  and the bundle's `log.md` names which one ran.
+- `okf check` gains `passage_malformed` and `subquestions_unindexed`
+  (19 rules).
+
+### Removed
+
+- **The old test track tied to one reference corpus is retired.** Its gate
+  row, its adapters and the tests that read those bundles are gone; public
+  tests and gates run on invented material. The retrieval gate's premises were
+  re-measured for BM25.
+
+### Known limitations added
+
+See [Known limitations](README.md#known-limitations): a question worded
+differently from the bundle reaches it first through the map's words, the
+retrieval gate is red on rows 5, 7 and 8, and speed was not measured.

+  actually carries: its numbers go stale the moment its bundle is rebuilt, one
+  copy per consuming project, and `okf card` derives the same numbers in under
+  a second so the generic document neither invents them nor states another
+  bundle's. The instantiated copy still refuses out loud (`bundle_mismatch`)
+  rather than answering from stale numbers — safe to keep, not enough to keep

+- **`okf card <folder>` SEES EVERY BUNDLE UNDER A FOLDER (v1.1 F1,
+  2026-09-21).** Until then only the server (`okf mcp --root`) could; the
+  generic skill read the one bundle it was pointed at. A path that carries no
+  `index.md` is a folder (`mcp_server.is_bundle`, discovery's own rule), and the
+  command prints `mcp_server.overview`: `okf_list` and `okf_describe` with no
+  bundle named, joined, computing nothing of its own -- one source, two doors,
+  held by a test comparing the printed bytes against the two functions. A

+  The reply is `mcp_server.call_ask` with no bundle named (or `--bundle-id` as
+  its `bundle_id`), serialised by the pre-pass's own `serialise` -- no ranking
+  of its own, held by a test comparing the bytes. `--question` repeats as
+  before. Every other flag acts on ONE bundle's cut and the server takes none
+  of them, so over a folder it is REFUSED by name with exit 2
+  (`consume.FOLDER_FLAGS` is the allowlist), never dropped; `--bundle-id` on a

+- **`okf check` READS A FOLDER'S REPLY AND THE SKILL TEXT SAYS SO (v1.1 F4).**
+  `contract_check.check_reply`: a reply carrying `answers` and no `bundle` is

+  named `[bundle_id]`, one every payload carries alike is reported once
+  unnamed (it is the SKILL's), an answer whose label is not its payload's
+  bundle is `answer_misattributed`, no answer at all is `payload_invalid`. No
+  rule was added to `RULES` -- the count stays 19 and a single payload's report
+  is byte-for-byte as before; a folder's report says `over N payloads`.
+  Contract SS 2.5.4 names the folder run, SS 8.11 fixes the reply. The
+  template's step 1 and 4 name the folder (`<FOLDER>`: both generators fill
+  a lower-case instruction, never a path -- the bundle's parent written
+  absolute named a checkout, and `test_the_generated_commands_name_this_repository_nowhere` fell on it); the generic header says the server comes first and the skill

+  lacks is read as the bundle's words it shares a leading WORD with
+  (`tokens_match`). A concept over `PASSAGE_CHARS` (4 000) is delivered as its

+  (question words held in NO form, after the bridge) and `coverage.weak`
+  (one such word, or nothing delivered) -- a reading, not a verdict; the

+  a question are stopwords in both languages. **C2:** `build_multi_payload`
+  (`okf consume --question A --question B`, `okf_ask` `questions`) reads the
+  bundle once (`bm25.prepare`), cuts each sub-question as alone and

+  `TITLES_PER_LINE` = 24 titles a line, lines capped at `MAP_MAX_BYTES` =
+  48 000 (`lines_truncated`). The card (`okf card`, `okf_describe`) carries it
+  as `map` and no longer carries `source_files`. The skill and the server
+  instructions say: read the map, 2-4 sub-questions in its words, ONE call.

+  bundle: the list came to **65.5 % of the written payload**, and not one of
+  those bytes counted against the budget the same payload reported — so a
+  reader was handed most of a file the budget line did not know about, to
+  learn one concept id per withheld concept with nothing beside it. The flag
+  bought the missing field and was off because buying it for a list that long
+  cost another 37.9 %. (The corpus is a consumer's; its counts are not
+  restated here, and the ratio is the argument.)
+  **`withheld` is now a MAPPING** (`CONTRACT_REVISION` = `okf-consumption/2`,
+  bumped so a consumer indexing the old key as a list breaks loudly):
+  `total` (equal to `denominators.withheld`, so SS 5.2's identity closes on the
+  NUMBERS), `by_rule` (the same total over the closed rule set), `nearest`
+  (the best-ranked drops BY NAME with title and source document, read off
+  `ranked` and not off `cut`'s id-sorted output, capped at
+  `WITHHELD_NEAREST_DEFAULT` = 20) and `complete`. Same question, same bundle,
+  after: **18.4 % of the old file**. `--withheld-full` brings the
+  whole list back and is what an instrument classifying EVERY miss asks for —
+  the retrieval gate and `okf_consume_measure` both pass it and assert
+  `complete`. `--withheld-nearest N` sets the cap. Three checker rules moved
+  with the shape, and one is the interesting case: `parent_unfollowable` used
+  `excerpts` + `withheld` as the bundle's own denominator, which a truncated

+disagree with the bytes beside it. It is therefore never stale, and one skill
+serves every bundle a project holds.
+
+**The card carries the bundle's map** (`map`): one line per source document —
+its name, then the titles of its concepts in document order — and documents
+whose names differ only in their numbers (a changelog per release) as one line
+with the count and the span. It is the bundle's own words, to write
+sub-questions in. The lines are capped at 48 000 bytes together
+(`lines_truncated` counts what a larger bundle leaves out), and a line lists at
+most 24 titles. The map replaced the card's flat `source_files` list.
+
+**Point it at a folder and it sees every bundle under it** (since v1.1 F):
+
+```sh
+okf card ~/okf                   # every bundle under the folder, each with its card
+```
+
+It prints what the server's `okf_list` and `okf_describe` give with no bundle
+named -- the listing (id, ref, concept count, directory), the directories that
+look like a bundle and cannot be read as one, and every bundle's card -- and it
+computes nothing of its own: the command calls the server's two functions. A
+bundle added or rebuilt under the folder is in the next run's answer with
+nothing regenerated. Pointed at one bundle, it prints that bundle's card as
+before; the command decides which it was given by the same rule discovery uses
+(a directory carrying an `index.md` is a bundle).
+
+**And one question -- or several sub-questions -- asks every bundle under the
+folder in one call:**
+
+```sh
+okf consume ~/okf --question "first sub-question" --question "second sub-question"
+okf consume ~/okf --question "..." --bundle-id my-bundle   # just one of them
+```
+
+The reply is the server's `okf_ask` with no bundle named, byte for byte: the
+budget split between the bundles, one payload per bundle, and every excerpt
+carrying the id of the bundle it came from. There is no ranking of its own.
+The flags that change how ONE bundle is cut (`--ref`, `--ranking`,
+`--no-source-quota` and the rest) are refused over a folder, by name, rather
+than dropped, because the server takes none of them; point at one bundle to use
+them.
+
+`okf check --payload` takes that reply as well as a single payload: every
+bundle's payload is held to every rule on its own, a finding is named with its
+bundle, and an answer labelled with a bundle its payload does not describe is a
+finding (`answer_misattributed`). The generic skill tells its reader both
+forms, and says to use the server's tools first where they are registered.
+
+`okf skill <bundle> --for-bundle` still writes the per-bundle form, with the
+identity and the numbers measured into the text — which is exactly what makes
+that file stale the moment the bundle is rebuilt. It refuses out loud when it
+was not regenerated (`bundle_mismatch`), so its cost is a stopped session
+rather than a wrong answer; that is why it is no longer the default.

+
+   This clause said "context the pre-pass withheld was withheld deliberately"
+   until 2026-09-20, which a skill reasonably read as "one run per question".
+   Measured on a large real bundle, the first run's cut is one ranking's
+   answer to one wording, and no wording of the operator's question put the
+   right document inside the cut — so a rule against a second run is a rule
+   against finding it at all. The `withheld` block exists in the shape it does
+   so that a second run can be aimed rather than guessed.
 3. The skill MUST declare the cut in its output rather than reporting as though
    it had read the bundle. An undeclared cut is a denominator failure (§ 5)
    dressed as an answer.
 4. A conformant skill MAY be handed a payload by any transport. The transport is
    not part of this contract.
 
+### 2.5 Working method
+
+A conformant skill MUST state a **working method** — how a question becomes
+searches — and MUST NOT state one that stops at a single run.
+
+1. It MUST tell its reader to read the bundle's own map before searching, and
+   to put the question into the bundle's terms. A bundle in one language and a
+   question in another share few tokens, and a pre-pass matching tokens then
+   ranks on almost nothing.
+2. It MUST tell its reader to split a broad question into sub-questions written
+   in the bundle's own terms, and to give every sub-question to the pre-pass —
+   in ONE run where the pre-pass takes several (§ 8.9), otherwise one run each.
+3. It MUST say that several runs are permitted and expected, and MUST NOT
+   contain a sentence forbidding a second run with other terms. Both the
+   `withheld` near misses (§ 5.3) and § 2.2 exist so that the second run can
+   be aimed.
+4. Where more than one bundle is in scope, it MUST tell its reader to run the
+   same sub-questions against each — in ONE run over the folder that holds
+   them where the pre-pass takes a folder (§ 8.11) — and to keep each piece of
+   material attributed to its bundle.
+5. It MUST tell its reader to assemble ONE answer — ordered by sub-question,
+   stating which source holds where sources disagree and with which version,
+   and saying what the bundle does not cover.
+
+### 2.6 Answer form
+
+A conformant skill MUST state an **answer form**, and that form MUST put the
+answer before the audit trail.
+
+1. The answer is written in the questioner's language, whatever language the
+   bundle is in, in ordinary prose.
+2. The instrument's vocabulary stays out of it: withholding-rule names,
+   digests, budget lines and the word *denominator* describe how the answer
+   was produced, not what it says.
+3. Source references are short and of the kind a textbook gives — the document
+   and the section, plus the bundle where more than one was read.
+4. The audit trail of § 3, § 5 and § 7 — the markings, the three counts, the
+   ref, the rules the declined concepts fell under — is written when the
+   questioner asks for it, or into an artefact that will travel without the
+   skill (§ 8's document mode), and otherwise MAY be omitted from the answer.
+   The obligation to HOLD a marking and a source for every claim is unchanged:

+
+`tools/okf_soek_gate.py` measures what a reader actually RECEIVES from a
+collection at the shipped defaults. It reads its question sets from this
+directory and the collection from `--bundle`; **neither is committed here.**
+
+**The sets are `.gitignore`d and are placed here by hand, by whoever runs the
+gate.** They are INPUTS, never constants: that is the rule
+`tools/okf_retrieval_gate.py` already states for a gold set, and this
+directory inherits it. A set that is absent is reported
+`IKKE KJOERT -- fixture mangler` and counted RED — never as 0 hits, and never
+as a quiet pass. So a machine without the sets cannot mistake silence for a
+green row, and nothing about anyone's corpus reaches a public mirror.
+
+A set is **FROZEN**: it is copied verbatim from wherever it was written,
+nothing here is edited to make a row go green, and a set whose bytes move is a
+new set with a new name.
+
+## The four files and the shape each must have
+
+| File | Shape | Units |
+|---|---|---|
+| `fase-sporsmaal.json` | `{"questions": [{id, question, fasit: [{doc, quote}], release_only}]}` | the phase set, with a `release_only` class |
+| `holdout-sporsmaal.json` | the same shape | a blind hold-out |
+| `norske-sporsmaal.json` | `{"sporsmaal": {id: text}}` — the same ids, asked in plain Norwegian; the fasit is read from the phase set by id | the phase set's ids |
+| `delsporsmaal.json` | `{"delsporsmaal": {id: [...]}, "operator": {question, hit_rule, gold: [{doc, section}]}, "negative": {pass_rule, questions: [{id, question}]}}` | one list per id, the operator's question by two routes, known negatives |
+
+Each set carries its own `hit_rule`, and the gate implements it verbatim
+rather than restating it: an excerpt whose `source_file` matches a fasit
+entry's document **and** whose text contains that entry's quote (case folded,
+whitespace collapsed). Any one fasit entry suffices. The negative set carries
+a `pass_rule` instead, because a question the collection does not cover is
+passed by SAYING so, not by returning nothing.
+
+## The collection
+
+The collection is not a fixture here either — it is far too large to commit.
+Build one with today's code and point the gate at it. It is built with
+`--gate none` and otherwise at the shipped defaults: the sources are the
+vendor's own public documentation, and the screen is for material of unknown
+origin — at the default tier it refuses some of these pages outright, and every
+refused page would read here as a build failure the search never had a chance
+at:
+
+```sh
+okf project <sources> --out <scratch> --gate none

+```
+
+`okf build <sources> --bundle <dir> --bundle-id <id> --okf-version 0.2
+--gate none` writes the same concept bytes.

+collection is missing the gate exits **2** with its reason rather than
+reporting 0 hits against nothing.

+- Declare the cut in your output when the questioner asked for it. Reporting
+  as though you had read the whole bundle, when you were handed a bounded
+  window, is the denominator failure below with extra steps.
+
+## Working method
+
+Five steps, in this order. The pre-pass is step three, not step one: a question
+asked in the wrong words reaches the wrong concepts however good the ranking is.
+
+**1. Understand the question first.** Read the bundle's `map` before you search
+it — `okf card <BUNDLE_ROOT>` prints it: one line per document with its section
+titles, a series of like-named documents as one line. Pointed at a FOLDER of
+bundles, the same command lists every bundle under it, each with its map, so
+you see what each one covers before you choose. Then put the question
+into the bundle's own words: a bundle written in one language and a question
+asked in another share few tokens, and the pre-pass matches tokens. Take the
+terms from the map's titles, not from your vocabulary.
+
+**2. Split a broad question into 2–4 sub-questions.** One search for a question
+with four parts returns the best eight concepts for the average of the four,
+which is often the best eight for none of them. Write the sub-questions down;
+they are also the shape of the answer.
+
+**3. Search all sub-questions in ONE run. Several searches are normal, and
+searching again is allowed and expected.** Give the pre-pass every sub-question
+at once:
+
+```sh
+okf consume <BUNDLE_ROOT> --question "first sub-question" --question "second sub-question" --out /tmp/p1.json
+```
+
+Each sub-question is ranked alone and the answers are interleaved; every
+excerpt names the `subquestions` it answered. After each run, read two things:
+what came back, and what lay just outside the cut. `withheld.nearest` names
+the best-ranked concepts that missed, with their titles — if one of them is
+what you were after, that is a signal about the WORDS, not a closed door. Search again with the words that concept uses, or
+ask for it by name. There is no limit on runs and no penalty for a run that
+found nothing; a run that found nothing is a measurement, and its denominator
+is worth carrying. When `coverage.weak` is true — a word of yours the bundle
+holds in no form (`coverage.absent_terms`), or nothing came back — rephrase in
+the bundle's own words, and if it stays weak, say the bundle does not cover it.
+
+**4. Several bundles, one run.** When more than one bundle could answer, give
+the pre-pass the FOLDER that holds them instead of one bundle: it asks every
+bundle under the folder with the same sub-questions in ONE run, splits the
+budget between them, and names the bundle on every answer and every excerpt.
+`--bundle-id` narrows it to one of them.
+
+```sh
+okf consume <FOLDER> --question "first sub-question" --question "second sub-question" --out /tmp/p1.json
+```
+
+Keep track of which bundle each piece of material came from. A claim is
+attributed to its bundle as well as its concept — two bundles can hold the same
+sentence with different authority.
+
+**5. Put it together.** Order the material by sub-question, not by rank. Where
+sources disagree, decide what holds NOW: the newest documentation or the
+highest version wins, and say which version you read. Say plainly what the
+bundle or bundles do not cover. Then write ONE coherent answer — not a list of
+excerpts with the assembly left to the reader.
+
+## Answer form
+
+Write for the person who asked: in the questioner's language, whatever
+language the bundle is in, and in ordinary prose.
+
+- **Plain words.** The instrument's vocabulary stays out of the answer:
+  not `below_k`, not `withheld`, not a `sha256`, not a budget line, not the
+  word denominator. Those are how the answer was produced, not what it says.
+- **Short source references, as a textbook gives them**: the document and the
+  section, and the bundle too when more than one was read — "Brukerhåndbok § 4.2" and
+  not a 64-character digest. A reader who wants the file can be told where it
+  is; a reader who wants the answer should not have to step over the plumbing
+  to reach it.
+- **Say what is not covered** in one sentence, in the same prose. A gap stated
+  plainly is worth more than a table of rules nobody reads.
+- **The audit trail is a choice.** The markings, the three counts, the ref and
+  the rules a concept was dropped under go to a file, or to the end of the
+  answer, only when the questioner asks for them — or when you are producing a
+  document that will travel without you. Otherwise the answer is the
+  deliverable.
+
+The markings below are the discipline BEHIND the prose. Every claim still has
+exactly one of them and a source you could produce on request; what changed is

+"""BM25 over a bundle's concepts: the default ranking of `okf consume` (v1.1 C1).
+
+WHY IT REPLACED THE FUSION. The earlier ranking fused three signals -- token
+overlap with the title, token overlap with the body, and a document prior --
+and two of them rewarded the wrong thing on a large collection: the document
+prior favoured big documents full of common words, and the rarity weight gave
+its MAXIMUM weight to a word that occurs nowhere in the collection. BM25 has
+neither property, needs no new dependency, and ranks in milliseconds. The
+measurement that chose it lives with the measurement; this module states the
+mechanism.
+
+TWO SIGNALS, FUSED BY RANK.
+
+- **Passage** -- every body is cut into windows of `WINDOW_CHARS` characters
+  every `WINDOW_STEP`, each window is a BM25 document, and a concept scores its
+  BEST window (pure max). A narrow factual question is answered by one place
+  in a concept, and a sum over windows -- even a damped one -- rewards a long
+  concept for mentioning a word often.
+- **Field** -- one BM25 document per concept: its title three times, its
+  directory path and source file name twice, then its body. A broad question
+  is answered by what a section is CALLED, and a passage never sees the title.
+
+Fused by reciprocal rank (`RRF_K`, the constant the old fusion used). A signal
+that scored a concept zero contributes nothing to it, and concepts that tie
+within a signal share the group's first rank -- so neither a word the
+collection lacks nor alphabetical order can lift a concept.
+
+**A word the collection does not hold weighs exactly zero** (`idf` of a term
+with `df == 0`), which is the property the old rarity weight had backwards.
+
+Deterministic: every sort breaks ties by `concept_id`, and no float leaves this
+module except as an ordering key.

+"""The map of a bundle: its documents and their titles, in its own words (v1.1 C5).
+
+WHY IT EXISTS. The ranking matches words, and a question put in words the
+collection does not use finds little however good the ranking is -- a question
+asked in one language of a collection written in another most of all. The
+reader closes that gap by rewriting the question into two to four
+sub-questions in the collection's OWN words, and the one place those words
+are listed is the collection itself. This module lists them, compactly enough
+to be read before the first question: one line per source document, its name
+and then the titles of its concepts in document order.
+
+A SERIES IS ONE LINE. Documents whose names differ only in their numbers -- a
+changelog per release, a note per week -- are one kind of document, and four
+hundred lines saying so crowd out everything else a reader needs. They are
+written as one line: the name with every number as `#`, how many documents,
+the first and the last by natural order, and the titles across the series that
+are words (a title that is only a version number names nothing).
+
+DERIVED, NEVER STORED, like the card that carries it: the map is recomputed
+from the bundle on every call, so it cannot disagree with the bytes beside it.
+Deterministic: every order is by name, by position or by a count with the

+"""The search gate for `okf consume` -- one command, one exit code (order B).
+
+WHAT IT ASKS. For a collection and a frozen question set: of N measurement
+units, how many does the payload a reader actually RECEIVES carry the fasit
+for? It measures the DELIVERY at the shipped defaults (`consume.DEFAULT_K`,
+`consume.DEFAULT_LIMIT`), never an internal rank -- a concept the ranker found
+and the cut dropped is a miss here, because it is a miss for the person asking.
+
+WRITTEN RED, BEFORE ANY CAPABILITY. Nothing in this module changes the
+ranking, the fusion, the tokenisation, the cut, the segmentation or the
+defaults; it only measures them. It goes through `consume.build_payload`, the
+one entry point `okf consume` and the MCP server's `okf_ask` both use, so a
+number here is a number about the shipped product and not about a harness.
+
+THE GATE IS NOT IN THE TEST SUITE. It is red against a real collection by
+construction, and a red test in a green suite is a suite nobody reads. The
+measuring instrument -- the hit rule, the counting and the missing-fixture
+state -- IS in the suite, against a synthetic corpus
+(`tests/test_soek_gate.py`).
+
+THE SETS ARE INPUTS, NEVER CONSTANTS. `tools/okf_retrieval_gate.py` states the
+rule and this module inherits it: a real gold set names documents in a
+consumer's corpus, and this repository is public. A set arrives as a file under
+`--sets` (default `eval/soek/`). A set that is ABSENT is reported
+`IKKE KJOERT -- fixture mangler` and counts RED: "not run" and "no hits" are
+two different facts about the world, and collapsing them would let a gate go
+green by having less to measure.
+
+THE HIT RULE IS THE SETS' OWN, VERBATIM. From the sets' `hit_rule`
+field: "A question is answered with source when at least one payload excerpt
+has source_file == <doc>.md for a fasit entry AND contains that entry's quote
+(case-insensitive, whitespace collapsed). Any fasit entry suffices."
+
+EVERY MISS CARRIES ONE CLASS AND NOT A GUESS. `byggefeil` -- no fasit quote is
+in the collection at all, so no ranking could have delivered it. `soekefeil` --
+a fasit quote IS in the collection and was not delivered. The second denominator
+is read off the concept files on disk, never off the payload: the judge opens
+the bundle.
+
+THE COLUMN HEADS AND THE NOT-RUN MARKER ARE THE ORDER'S WORDS. Everything else
+here is English, per this repository's convention for a public repo.
