# ADR-0015: import what a player reads, and read what we already imported

status: accepted
date: 2026-08-06
decided by: agent, under the standing loop authorization
tier: M (structural M — imports more of an external dataset under AM-4's
budgets; chaos d8=1 → no override). Tier M merges survey and decision.

## Context

A player said *"I don't understand the GROUND card."* The card explains
itself in the edition and the engine never imported the explanation.

## The measurements this rests on

**Taken before deciding, because ADR-0011's own numbers were computed
against the wrong budget and the correction is the reason that ADR exists.**

**1. The gap is bigger than "one file of nineteen."**

| | |
|---|---|
| edition files in `ground-game` | **19** |
| vendored in clay-borg | **1** (`Problems.csv`) |
| columns in that file | **13** |
| columns the engine reads | **5** — `scenario_id`, `hidden_priority`, `point_value`, `required_solution`, `visibility` |
| scenarios in the file | **4** (`SCN_01`…`SCN_04`) |
| scenarios the engine deals | **1** — `SCN_01`, hardcoded at `lib.rs:1824` |

**Every Problem already has a `title` and `problem_text` sitting in a file
we vendored eight days ago**, and the page shows `Repair 2`. The cheapest
part of this pass costs no new bytes at all.

**2. ADR-0011's revisit condition is not triggered, and that is measured.**

ADR-0011 refused the `csv` crate and said the decision would be wrong *"if
this data ever grows nested quoting, embedded newlines, or multiple
dialects."* Across every candidate file:

| file | rows | fields with `,` | with `"` | with newline |
|---|---:|---:|---:|---:|
| Actions | 5 | 12 | **0** | **0** |
| Solutions | 24 | 5 | **0** | **0** |
| Modes | 3 | 6 | **0** | **0** |
| Scenarios | 4 | 2 | **0** | **0** |

**Zero doubled quotes, zero embedded newlines.** The hand reader's only
job is comma-in-quoted-field, which it already does. **The dependency
argument does not get re-run**, because the condition that would re-open
it is absent — not because re-running it would be inconvenient.

---

## D1 — read the columns we already have, first

`title`, `problem_text`, `front_rules`, `reveal_effect` and
`unresolved_effect` are in the vendored file and discarded at parse time.
They become part of `EditionProblem` and reach the page.

**This is the whole of observation 2's Problem half and costs zero new
dependencies, zero new files and no budget.** It is listed first because
a pass that imports three new files while ignoring eight columns of the
file it already has would be solving the interesting problem and not the
real one.

## D2 — vendor `Actions.csv`, `Solutions.csv`, `Modes.csv`

These carry the text a player reads:

- **Actions** — the five action cards' `title`, `tagline`, `rules_text`.
  The GROUND card's own words are here, and this is the reported defect.
- **Solutions** — `title` and `microcopy` per card, so a hand shows
  *"Ask What Happened"* rather than `Clarify`.
- **Modes** — the scoring mode's `title`, `tagline` and `rules_text`, and
  its `scoring_tiebreak`, which T07 needs and which we would otherwise
  have invented.

Each vendored with a digest and a provenance line, exactly as
`Problems.csv` was.

**Not vendored:** `BOM`, `Print_Manifest`, `Back_Designs`, `Symbols`,
`Design_Tokens`, `README`, `metadata` — production artifacts for a
physical print run, with no meaning to a simulator.

**`Extensions.csv` is not imported, and the reason is stated rather than
assumed:** it names content the designer deliberately placed *outside* the
core (`not_in_core_reason` is a column). Importing it would put
non-core content in an engine whose whole claim is that it plays the
edition as printed. **It is now known to exist**, which was the actual
risk.

**`Relations`, `DARVO`, `Tokens`, `Glossary` are deferred**, not refused:
they describe mechanisms `GroundRules.md` already encodes as rules, and
nothing a player reads is missing from the page without them. If T02 finds
a seat's DARVO stage needs its own words, that is the trigger.

## D3 — the hand reader stays

Measured above. ~50 lines we own against 17,651 for `csv`, and the
grammar has not grown.

**What changes:** the reader becomes generic over "a vendored CSV with a
header" instead of being `Problems.csv`-shaped, because it is about to
have four callers. **A per-file copy is how a parser acquires four subtly
different bugs.**

**Falsifier, restated so it stays live:** if any future edition file
carries a doubled quote or an embedded newline, this decision is wrong and
`csv` is the answer. The check is one command and belongs in
`edition-check.py`.

## D4 — where text and rules disagree, that is a finding

`GroundRules.md`'s 59 rules were hand-derived from these files. Importing
the files puts the source beside the transcription for the first time.

> **A `rules_text` that contradicts a numbered rule is a register finding
> — kind `inconsistent` — not a quiet edit of either.**

Neither wins automatically: the dataset is authoritative on the *game*,
but our rule may encode a ruling `ground-game` has since made. The
register is where that gets resolved, and `ground-game` owns the answer.

**This is the most valuable thing the import can produce** and it is
adversarial to our own work, which is why it is written down before
anyone looks.

## D5 — the scenario stays hardcoded, and that is now visible

`SCN_01` at `lib.rs:1824`, one of four. Not changed here: choosing a
scenario is a setup-surface change (`Setup` has `preset` and `patch`), and
bundling it into a text-import pass would make both harder to review.

**Recorded as an open item rather than left as a surprise** — the engine
has never played three quarters of the shipped content, and nobody had
said so.

## Consequences

- `editions/ground-darvo-r0/` gains three files, each with a digest.
- `edition.rs` gains a generic reader and four typed views over it.
- `EditionProblem` gains the text columns already present.
- `edition-check.py` verifies the new digests and the no-doubled-quotes
  condition D3 rests on.
- The page can show the game's own words (T02).

## What was rejected

| rejected | why |
|---|---|
| the `csv` crate | its revisit condition is measurably absent (§2) |
| importing all 19 files | production artifacts have no meaning to a simulator |
| `Extensions.csv` | deliberately non-core content; importing it would break the as-printed claim |
| a per-file parser | four copies acquire four subtly different bugs |
| resolving text-vs-rules conflicts in place | that is a finding, and `ground-game` owns the answer |
| changing the scenario here | a setup-surface change bundled into a text import makes both harder to review |
