KP:1 Public Draft — 2026-05 (v0.8.1-preview)

Patch preview for the KP:1 v0.8 line.

Changes:

• Promotes voice-view register metadata into the PACK.yaml conformance schema.
• Adds optional views[].register with the four primary VOICE.md registers: plain, curatorial, technical, investor.
• Adds optional free-form views[].sub_register for locale-specific register refinements.
• Adds maximal fixture coverage for register and sub_register.
• Refreshes current public preview markers to v0.8.1-preview.
• Adds scripts/check_links.py for local Markdown link checks.

Compatibility:

• No breaking schema change.
• Existing v0.8.0-preview packs remain valid.
• sub_register remains informational and free-form.

Verification:

• python3 conformance/run.py: 19/19 passed.
• python3 scripts/check_links.py: no broken links.
• PR #17 CI passed and main CI passed after merge.

KP:1 Public Draft — 2026-05 (v0.8.0-preview)

Editor's draft. The substantive format (claim grammar, manifest schema, conformance suite) is stable; companions RECONCILIATION.md and PLAYBACK.md are explicit experiments with documented evolution paths.

Headline changes vs v0.7-preview:

• Three normative lanes — spec/README.md declares that KP:1 carries normative weight across CORE.md (implementer surface), SPEC.md (full normative + rationale + ecosystem), and topic-authoritative companions.
• AI-first packaging — root-level AGENTS.md task-routing file plus spec/AUTHORING.md producer-side decision rubrics. A cold AI agent can read AGENTS.md and load only the files relevant to its task.
• Bifurcation — spec/RATIONALE.md (NEW companion, informative) houses Design Principles, Style Systems rationale, and the Relationship to Existing Standards table previously interleaved into SPEC.md normative prose.
• Companion-doc additions — RECONCILIATION.md stub, EXTENSIONS.md catalog, LIFECYCLE.md §6 supersession cascade, VOICE.md register axis, MULTILINGUAL.md en-GB row + sub-registers.
• Two new reference examples — examples/art-acquisition-decision.kpack (buyer-side, walks AUTHORING.md rubrics end-to-end) and examples/auction-house-consignment-review.kpack (consigner-side decline path with cross-pack ↔ references).

Conformance: 19/19.

• Added 4 negative fixtures bringing negative-fixture coverage to one per substantive SC the runner enforces.
• SC-12 (NEW) — When nature is prediction, confidence MUST be ≤ 0.95 (predictions about future states have irreducible uncertainty).
• New --pack PATH flag for validating arbitrary packs outside the bundled set.
• New Makefile convenience wrapper.
• Cross-pack reference parsing extended in the runner (↔pack#section form).

Discoverability — new optional spec_uri and spec_version manifest fields let a sealed .kpack archive self-describe to a cold receiver.

No core schema break. Pre-v0.8.0 packs continue to validate.

Quick start:

```bash
git clone https://github.com/tymofiy/kp.git
cd kp
pip install -r requirements.txt
python3 conformance/run.py # 19/19 expected
python3 conformance/run.py --pack path/to/your-pack.kpack
```

Or via the new Makefile:

```bash
make conformance # 19/19 expected
make pack PACK=path/to/your-pack.kpack
```
