# Module: `problem_stress.flat_any_open`

| | |
|---|---|
| **aspect** | `problem_stress` |
| **role** | End of round: if **any** Problem unclaimed → **each** seat +1 Stress |
| **status** | measured → reject as sole pressure (H1-A); keep for A/B |
| **legacy** | H1-A half of `h1-problem-stress` |
| **measurement** | [RPT-0004](../../../../reports/260808-clay-borg-h1-measured.md) |

**Compose with:** any `end_condition`, `problem_deal`, `attack_relief`.  
**Conflicts with:** other `problem_stress.*` modules (one per aspect).

Known result: flat tax → solve-rate collapse at 3p+ under greedy (when used alone or with H1-B).
ADR-0022 + CB-WP-0048 T00: the selector decision, and the mirror held The maintainer's observation decided the design: aspects partition the GAME, strata partition our apparatus, and they are orthogonal. A module is one coordinate change in aspect space with an obligation in every stratum. So aspect identity must NOT be Rust types -- an aspect ground-game adds would make clay-borg fail to parse a configuration rather than fail to run it, welding the two coordinate systems at the one place they must stay independent. Chosen: identity as data (Configuration round-trips anything the catalog names), behaviour exhaustive (Rules, no catch-all), resolve() between. Decisive argument: the catalog ALREADY ships modules with a rules_delta and status: proposed, so a per-aspect enum would report them as "unknown module" -- indistinguishable from a typo, a false statement about the edition, and this project's signature failure shape. Two facts need two errors. Federating design authority is permanent, so the representation must outlive the implementation. Legacy ids alias forever through the catalog's own legacy_experiment_id, on the standard-Np precedent: 26 recordings name them and the expansion is exact, so there is nothing to deprecate. T00 done: the schema-2 mirror had arrived with no digests (19 files) and edition-check was red. Digests are now generated by WALKING editions/, not typed -- two reviews already found hand-written lists that made their own controls vacuous, and a mirror that grows a directory is what breaks a maintained list. PROVENANCE-catalog.md was a file inside the mirrored tree that upstream does not have; folded into our own PROVENANCE.md, since provenance about the mirror does not belong inside the thing it describes.
