CB-WP-0037 T01: F18 gets a reproduction, and F24 falls out of it

F18 was the only open finding clay-borg owns, the only register row
lacking a reproduction, and the only off-target metric. It is also
understated: it reads as display data, but among the 14 unvendored files
are DARVO.csv (mandatory_effect, advance), Relations.csv (formation,
breaking) and Scenarios.csv — rules the engine already implements from a
secondary source and has never checked against the primary one.

The reproduction records column reads AT THE ACCESSOR rather than counting
them from the source: a list beside the code would be a second copy of a
fact the get calls already carry, and grepping would over-count because
six column names are shared between vendored files.

The first version was wrong in this repo's signature way — it watched
Table::at only, so it called visibility, required_solution and point_value
unread when the engine reads all three through problems_of's own index
lookups. Correct about the accessor, wrong about the engine: the ADR-0018
family, committed inside the artifact built to measure it. Problems.csv
went 7/13 to 10/13 once the manual reader was recorded too.

F24 raised: solution_deck() is a Rust literal that never opens
Solutions.csv. It agrees today, which is the point — the engine is right
by maintenance coincidence rather than by reading. Role `default`, with a
test that goes red the moment either side moves.

open, lacking a reproduction: 1 -> 0.

+
+## Why this, and why now
+
+**F18 is the only open finding clay-borg owns**, the only row in the
+register lacking a reproduction, and the only metric off target
+(`open, lacking a reproduction: 1, target 0`). F17 is with `ground-game`.
+
+**And F18 is understated.** Its prose describes display data — *"the cards
+cannot say what they do"* — and calls itself fixed by CB-WP-0028. Measured
+now: **5 of 19 files vendored**, and among the 14 unread are
+
+| file | what is in it |
+|---|---|
+| `DARVO.csv` | `mandatory_effect`, `target_memory`, `advance` — **the DARVO sequence, as rules** |
+| `Relations.csv` | `formation`, `breaking`, `rules_text` — **how Bonds and Rivalries form and break** |
+| `Scenarios.csv` | four scenarios with their setups — **the engine hardcodes one** |
+| `Rules_Text.csv` | 21 sections of the rules themselves |
+| `Player_Mats.csv` | includes `choice_rule` and `stress_track` |
+
+**The engine implements DARVO and relation behaviour without ever having
+read the edition's statement of them.** That is not inert display data; it
+is rules taken from a secondary source and never checked against the
+primary one.
+
+A spot check is reassuring — REVERSE's engine path flips Focus to Blame,
+gives the target +1 Stress, takes a Protection and reduces the owner's
+Stress by 2, exactly as `DARVO.csv` states. **Reassuring is not checked**,
+and the whole point of this repo is the difference.
+
+## Task: give F18 a reproduction
+
+```task
+id: CB-WP-0037-T01
+status: done
+priority: high
+```
+
+An artifact that measures the gap instead of asserting it: **per edition
+file, columns present against columns the engine reads.**
+
+**Controls:**
+- **it can go red and green** — improving coverage must move it, or it is
+  not measuring coverage (ADR-0006 D3);
+- it reports **per file**, never a single ratio: *"5 of 19"* is the sum
+  shape GameDesign §1.2 exists to refuse;
+- **an absent upstream is reported absent, never as a pass** — the shape
+  `edition-check` already uses.
+
+**Done 2026-08-07.** `the_engine_reads_only_part_of_what_it_vendored`.
+**F18 has a reproduction**, and the register's one off-target metric —
+`open, lacking a reproduction: 1` — is now **0**.
+
+**Recorded at the accessor, not counted from the source.** A list of
+column names beside the code would be a second copy of a fact the `get`
+calls already carry; grepping the source would over-count, because six
+column names are shared between vendored files.
+
+**And the first version was wrong in this repo's signature way.** It
+watched `Table::at` only, so it reported `visibility`, `required_solution`
+and `point_value` as unread when the engine reads all three —
+`problems_of` predates `Table` and resolves its own indices. Correct about
+the accessor, wrong about the engine: **the ADR-0018 family, committed
+inside the artifact built to measure it.** Problems.csv went 7/13 → 10/13
+once the manual reader was recorded too.
+
+Measured, per file, never as a ratio:
+
+| file | read | unread |
+|---|---|---|
+| Problems.csv | 10/13 | `problem_id`, `symbol_id`, `back_design_id` |
+| Actions.csv | 4/9 | `symbol_id`, **`resolution_order`**, **`target`**, **`stress_restriction`**, `designer_note` |
+| Solutions.csv | 4/8 | **`suit`**, `symbol_id`, **`quantity`**, `back_design_id` |
+| Modes.csv | 5/7 | `mode_type`, `back_design_id` |
+| Tokens.csv | 6/9 | `shape`, `size`, `symbol_id` |
+
+**`resolution_order`, `target` and `stress_restriction` are rules**, and
+the engine implements all three from `GroundRules.md` without reading the
+edition's statement of them. That is T02's work.
+
+**F24 raised**: `solution_deck()` is a Rust literal — six of each suit,
+never opening `Solutions.csv`. **It agrees today** (24 rows, six per
+suit), which is why it is `inert` with role `default` rather than a
+counterexample: right by maintenance coincidence, not by reading.
+`the_hardcoded_deck_still_matches_the_edition` is the guard until T02
+deletes the literal, and it turns red the moment either side moves.
+
+## Task: vendor what carries rules, and check it against the engine
+
+```task
+id: CB-WP-0037-T02
+status: todo
+priority: high
+```
+
+`DARVO.csv`, `Relations.csv`, `Scenarios.csv` first — they carry
+mechanism.
+
+**Controls:**
+- **every divergence between the edition's text and the engine is a
+  finding**, raised, not quietly fixed: the edition is `ground-game`'s to
+  rule on;
+- **agreement is recorded too.** A survey that finds nothing and leaves no
+  trace cannot be told apart from one never run (CB-EV-0027 §3);
+- AM-4's dependency and size budgets hold, or the pass says what it cost.

+
+`Symbols`, `Design_Tokens`, `Back_Designs`, `BOM`, `Print_Manifest` are
+production and visual identity.
+
+**Control:** each becomes either a vendored file or an **ornament
+declaration with a falsifier** ([`OrnamentRegister.md`](../specs/OrnamentRegister.md)).
+**O4 already says nothing may be declared about `Player_Mats` or
+`Glossary` until they are read** — so read them or leave O4 alone.

+## Task: evidence

+```task
+id: CB-WP-0037-T04

+Say so either way, per rule, not as a count.
