test(consume): the retrieval gate, written red over nine rows

One command, one exit code, and no capability: nothing here changes the
ranking, the fusion, the tokenisation or the cut. For a frozen question set
against a bundle it asks how many of N measurement units the payload carries
the fasit for, gives every miss exactly ONE class, and asks the thing the
payload does not do at all -- say so when it does not know.

Today, on the synthetic corpus this repository generates and the five sets it
ships pinned by sha256: rows 1 (9 of 9), 2 (7 of 7) and 6 (9 of 9) green;
3 (2 of 5), 4 (3 of 6), 5 (0 of 1), 7 (11 of 13), 8 (not run) and 9 (0 of 6)
red. GATE RED, exit 1.

- Row 3 is the finding to read first. In a bundle built from ONE source
  document, every concept past the first two carries that document's
  `source_file`, so a concept the RANK had already lost is withheld as
  `source_quota_exceeded`. The truth is decided by the SAME cut run without
  the quota -- PM measured the same lie on 13 of 25 real misses 2026-09-17.
- Row 4 is the second. No payload key says "this bundle does not answer
  that", so the only honest reading today is `delivered == 0`; three of six
  controls come out right and the three that do not get eight excerpts and no
  statement. A control the bundle DOES answer must come back unmarked, or the
  marking says nothing, so both directions sit in the same row.
- A miss has exactly one class -- (a) not in the bundle, (b) below k, (c) cut
  by quota or budget, (d) delivered without the citation, (e) other -- and
  each is FORCED by its own fixture. An unplaced miss takes the row to 0 of N.
- The judge opens the bundle. Every concept is read off disk before a payload
  is built, a delivered excerpt whose text is not the concept file's bytes is
  not a hit, and the two title forms come from `quality` rather than being
  written a second time.
- FELLED means a row got WORSE, never merely that something changed: removing
  the quota makes row 3 green, and counting that as a kill would credit this
  gate with a check it does not have. The two survivors are reported with what
  they measured -- the document prior dead and RRF_K flattened each moved 0
  ranks and 0 deliveries on these fixtures -- and with a mechanism for each.
- Rows 8 and 9 are never green by leaving something out. The three real sets
  are read from path + sha256 and never committed: a gold set names a
  consumer's documents and this repository is public. K2 is 0 of 6 because the
  gold set exists nowhere while its bundles do.

Denominators re-measured against the sources 2026-09-19, and all four hold:
wiki 20 questions / 29 fasit entries (sha 972d0f57...), R761 8 (S1-S6 + KP +
KN), vegnormal 32 questions / 43 must_cite, K2 6. PM's 45 of 70 is itself a
mixed sum -- wiki at question level, vegnormal at citation level -- so this
gate carries it labelled as recorded and never sums the two granularities.

46 tests, each failing row driven both ways through inputs rather than by
editing the row. No network (the socket guard is fired before its silence
counts), no private corpus, no clock.

+- **Judge the RETRIEVAL: `python3 tools/okf_retrieval_gate.py` (2026-09-19).**
+  A separate question from `okf quality` and a separate command: quality asks
+  what a bundle looks like, this asks whether the payload for a question
+  carries the fasit. **Written RED, no capability**: nine rows, exit 0 only
+  when all are green, 1 otherwise, 2 on wrong input, `--json`. Rows 1-4, 6, 7
+  run against a synthetic corpus this repo GENERATES and four sets it ships
+  pinned by sha256 -- no network, no private corpus, no clock; a set whose
+  bytes moved is exit 2, never a quiet continuation, because **a gold set is
+  an INPUT and never a constant here** (`okf_consume_measure.py`'s rule, and
+  this repo is public). Today: **1 (9/9) - 2 (7/7) - 3 (2/5) - 4 (3/6) -
+  5 (0/1) - 6 (9/9) - 7 (11/13) - 8 not run - 9 (0/6)**, `GATE RED: rows 3,

+  Rows 8 and 9 are never green by leaving something out: the three real sets

+  standard where a question cites two), and K2 is **0 of 6 because the gold

+  wiki **20** questions / **29** fasit entries (sha `972d0f57...`), R761
