From f9ff41a653dcd2a57cef890c677699ab4f225156 Mon Sep 17 00:00:00 2001 From: Seongho Bae Date: Mon, 17 Aug 2026 19:06:17 +0900 Subject: [PATCH 1/5] feat(method): refuse house-voice style as unique content House-voice style residue stays explicit method structure (ADR 0004 and 0012). It is not unique latent content and is not erased by a stopword list. Recovery is the computed share of style kinds that match known truth versus collapsing every token to unique content. --- ARCHITECTURE.md | 1 + CHANGELOG.md | 1 + Cargo.lock | 4 + Cargo.toml | 2 + README.md | 3 +- crates/style_source/Cargo.toml | 17 +++ crates/style_source/src/error.rs | 57 ++++++++ crates/style_source/src/kind.rs | 129 ++++++++++++++++++ crates/style_source/src/lib.rs | 22 +++ crates/style_source/tests/crate_contract.rs | 7 + .../tests/style_source_contract.rs | 67 +++++++++ docs/TRACEABILITY.md | 2 +- .../0004-shared-multilingual-latent-space.md | 2 +- ...ational-shared-latent-topic-measurement.md | 2 +- docs/adr/README.md | 4 +- docs/research/standards-and-literature.md | 2 +- docs/research/style-source-identity.md | 30 ++++ docs/validation/temporal-event-foundation.md | 1 + scripts/check_workspace_contract.py | 1 + 19 files changed, 347 insertions(+), 7 deletions(-) create mode 100644 crates/style_source/Cargo.toml create mode 100644 crates/style_source/src/error.rs create mode 100644 crates/style_source/src/kind.rs create mode 100644 crates/style_source/src/lib.rs create mode 100644 crates/style_source/tests/crate_contract.rs create mode 100644 crates/style_source/tests/style_source_contract.rs create mode 100644 docs/research/style-source-identity.md diff --git a/ARCHITECTURE.md b/ARCHITECTURE.md index ffe514db..807b3a16 100644 --- a/ARCHITECTURE.md +++ b/ARCHITECTURE.md @@ -61,6 +61,7 @@ boundaries above remain the target modular MSA architecture. | `tepp_simulation` | known-truth temporal/event data generation | | `validation_core` | RMSE, bias, coverage, graph, and Monte Carlo metrics | | `tepp_api` | versioned DTO, schema, and export contracts | +| `style_source` | house-voice style residue is not unique latent content and not stopword deletion | No crate exposes placeholder production behavior in Task 1.
