# Start here by role

The corpus is large because it preserves both discoveries and failed routes. Enter through a task, not through chronology.

| You want to… | Read first | Then do one bounded thing |
|---|---|---|
| Understand the whole claim | [Reading contract](READING_CONTRACT.md), [current synthesis](syntheses/the_admissibility_frontier_current_synthesis.md) and [Edition 3.2](../book/edition-3/README.md) | Challenge the Jordan–carrier–Lie framing at its weakest typed edge without reversing its explanatory order. |
| Explain, translate or summarize | [Explanatory standard](EXPLANATORY_STANDARD.md) | Put things before names; give the reason, difference, two-dimensional status, implication, non-implication and next discriminator for every material bridge. |
| Check the mathematics | [Book result ledger](../book/edition-3/chapters/08-result-ledger.md) and cited certificates | Reproduce one theorem or replace one computational certificate with a conventional proof. |
| Work on Furey/division algebras | [Technical guide](claims/0000-0099/03_furey_technical_algebraic_guide.md) and [source-provenance matrix](programmes/document-acceptance/furey_source_provenance_matrix_20261024.md) | Separate a primary-source result from a later corpus deduction and verify the map. |
| Work on exceptional mathematics | [Exceptional horizon](../book/edition-3/chapters/07-exceptional-horizon.md) and [paper-worthiness ranking](programmes/closure/programme_closure_08_paperworthiness_ranking.md) | Test one carrier/invariant/intertwiner; do not infer a physical identification from a shared number. |
| Work on dynamics or open systems | [Admissibility frontier](../book/edition-3/chapters/08-admissibility-frontier.md) and [dynamic response atlas](programmes/admissibility/admissibility_06_dynamic_response_geometry_detection_metastability.md) | Specify the update, invariant, record and distinction from measurement-conditioned change. |
| Build an experiment | [Experiment atlas](programmes/frontier-physics-targets/frontier_experiment_atlas_v1.md) and [starter kit](programmes/frontier-physics-targets/experiment_starter_kit.md) | Turn one design into a preregistered observable/nuisance/decision packet. |
| Work with detectors or data | [Detector frontier atlas](programmes/frontier-physics-targets/detector_frontier_atlas_v1.md) | Identify the detector quotient and add the cheapest channel that separates the leading collision. |
| Review current physics contact | [Research-frontier crosswalk](programmes/admissibility/admissibility_25_current_research_frontier_crosswalk.md) | Add primary literature and grade the contact as exact-object, shared-mechanism, analogy or unsupported. |
| Write a paper | [Paper-worthiness ranking](programmes/closure/programme_closure_08_paperworthiness_ranking.md) and [manuscript kit](programmes/closure/manuscript_starter_kit.md) | Select one claim cluster with a proof spine, novelty boundary and independent reproduction plan. |
| Audit corpus truthfulness | [Full-corpus census](programmes/frontier-physics-targets/full_corpus_gate_census_v1.md), [manifest](registers/spin23_corpus_manifest.json) and [verification guide](../verification/README.md) | Find stale status, missing evidence, a broken link or a claim whose verb exceeds its certificate. |
| Improve public explanation | [Claimipedia editorial standard](../integrations/claimipedia/ARTICLE-EDITORIAL-STANDARD.md) and [sync packet](../integrations/claimipedia/CURRENT-SYNTHESIS-SYNC-20261024.md) | Write a standalone synthesis that preserves status, source and boundary. |

## The shortest reliable path

1. Read the [canonical reading contract](READING_CONTRACT.md), then the [current synthesis](syntheses/the_admissibility_frontier_current_synthesis.md).
2. Use the [explanatory standard](EXPLANATORY_STANDARD.md) and [glossary](GLOSSARY.md) to keep the things, reasons, carrier, selector, dynamics, detector and admissibility distinct.
3. Choose one item from the [49-topic live queue](programmes/frontier-physics-targets/open_topics_v1.md).
4. Open its controlling corpus links and kill test.
5. Return a proof, calculation, source, protocol, correction or explicit failure.

The contribution is complete when another reader can tell exactly what changed in the admissible map.
