# Frontier physics targets

This folder is the canonical navigation lane for physics targets in the corpus. It consolidates programme-level targets without replacing their source documents or promoting speculative material.

The lane is the practical face of the corpus's Jordan/Lie middle. Jordan and response structures say what can coexist and compose; Lie, symplectic and dynamical structures say how it can transform; the target register asks which of those structures survives scale, nuisance, detector and experimental gates. For the narrative connecting those layers, start with [The admissibility frontier: current synthesis](../../syntheses/the_admissibility_frontier_current_synthesis.md).

## Canonical artifacts

- [Corpus completion exit criteria](corpus_completion_exit_criteria_v1.md) — durable nine-gate target for dated physics–mathematics saturation; explicitly places current-input computational exhaustion below corpus completion.
- [Physics–mathematics adjacency candidates](physics_math_adjacency_candidates_v1.md) — generated first-layer EXIT-01 universe crossing every maintained topic with the applicable relation families; generation is non-evidential until each candidate is dispositioned.
- [Terminal-neighbourhood register](terminal_neighbourhood_candidates_v1.md) — passed EXIT-02 matrix applying eight reopening moves to every closed or blocked topic; regeneration reopens the gate when a new terminal topic appears.
- [Experiment exit audit](experiment_exit_audit_v1.md) — strict EXIT-03 field audit that measures what separates the existing design atlas from decision-complete experimental programmes.
- [Frontier exhaustion checkpoint](frontier_exhaustion_checkpoint_v1.md) — current whole-corpus result, frontier shape and ranked next tranches.
- [Finesse technology pathway](finesse_technology_pathway_v1.md) — converts certificate-preserving descent, detector lifting and memory closure into a 90-day launch, a shared finesse device and a strict anomaly-to-new-physics escalation ladder.
- [PageRank, Perron selection and the finesse trade-off](page_rank_perron_selector_bridge_v1.md) — exact control model for stationary-family collapse, explicit selector provenance, contraction and the price paid in structural fidelity.
- [Frontier physics target set](frontier_physics_target_set_v1.md) — human-readable map, priorities and use rules.
- [Per-target corpus assessments](frontier_physics_target_assessments_v1.md) — reach band, internal assets, missing join, promotion test and neighbouring targets for every FPT entry.
- [Target register](frontier_physics_target_register_v1.json) — machine-readable source of truth for the normalized target set and all declared crosswalks.
- [Coverage and provenance map](frontier_physics_target_coverage_map_v1.md) — maps the admissibility lanes, legacy branches, external validation set, speculative arcs, terminal new-physics gates and recent execution packets into the canonical targets.

- [Experiment programme overrides v2](frontier_experiment_programme_overrides_v2.json) — durable experiment-specific authorship for all transfer functions, covariance models, sensitivity calculations, decision gates, replication rules, release contracts and claim propagation; never overwritten by regeneration.
- [Transition-operator propagation audit](transition_operator_propagation_audit_v1.md) — scans every corpus Markdown document, propagates the eight-field operator-to-record boundary, and semantically separates genuine rate claims from effective poles, barrier metastability and unrelated uses of selection or matrix language.
- [Spectral-width propagation audit](spectral_width_propagation_audit_v1.md) — routes every effective-spectral candidate through the AZ-128 distinction between spectrum, effective damping, physical spectroscopy, detector folding and population lifetime.
- [Barrier and kinetic propagation audit](barrier_kinetic_propagation_audit_v1.md) — separates quantitative escape and first-passage claims from metastable selection, adaptive hysteresis, algebraic usage and navigation.
- [Transition-operator semantic dispositions](transition_operator_semantic_dispositions_v1.json) — durable human review of the rate-context keyword collisions that do not make an operator-to-rate inference.
- [Elliptic/hyperbolic/parabolic local alphabet](../admissibility/admissibility_129_elliptic_hyperbolic_parabolic_local_alphabet.md) — exact generator classification joining the quarter-turn, two-rail mirror and dual-number tangent seam while keeping physical branch selection open.

- [Global semantic-adjoint no-go](../admissibility/admissibility_134_no_global_semantic_adjoint_exists_on_the_current_claimipedia_relation_source.md) — proves the current source cannot close globally under any involution of the four relation types; only the Spin–Temple reciprocal cell survives.
- [Three-resonator parity-switch detector](../admissibility/admissibility_142_a_three_resonator_parity_switch_turns_the_dual_face_into_a_detector.md) — turns carrier, dual-face selector and triality detector into an executable three-mode experiment whose held-out cubic invariant is invisible to the first two spectral moments.

- [Observer, horizon and channel atlas](../admissibility/admissibility_140_observer_horizon_channel_atlas_and_exhaustion.md) — a MECE map of Unruh response, Hawking state/mode conversion, Kerr horizon/ergosurface/superradiance and nuclear open systems, with filled and unfilled regions plus explicit stop rules.
- [Observer, horizon and nuclear literature review](observer_horizon_nuclear_literature_review_v1.md) — primary and review literature mapped to the exact claims it supports and the stronger identifications it leaves open.
- [Observer/horizon/nuclear priority assessment](../admissibility/admissibility_141_observer_horizon_and_nuclear_priority_for_next_insight.md) — sensitivity-tested ranking that puts controlled (^{229})Th factorization first, Kerr multi-record consistency second, nuclear many-channel controls third, Unruh in the calibration role and Hawking as the foundational endpoint.
- [Where the next insight can enter](../admissibility/admissibility_145_where_the_next_insight_can_enter.md) — deepens that ranking into a common source–evolution–channel–detector factorization, shows exactly where the five areas differ, and maps every positive, negative and anomalous result to the next warranted move.
- [Lenses make many points: spectral type, multiscale closure and admissibility](../../syntheses/lenses_make_many_points_spectral_type_multiscale_closure_and_admissibility.md) — standalone analysis of the Becker--Yang counterexample: arbitrarily weak smooth nonnegative potentials can preserve the spectral set while replacing the continuous sector by dense pure point spectrum; derives the support/type/dynamics/scale/record distinction and a matched-control finite experiment.
- [Thorium-229 shared-parent/host-channel programme](../admissibility/admissibility_143_th229_shared_parent_host_channel_factorization_programme.md) — turns the leading precision lane into frozen specimen/intervention splits, explicit build/bridge/physics/propagation gates and an external-metadata stop rule.

## Scope

The unit of this register is a **research target**, not a document. Claims, evidence files and programme notes attach to targets as provenance. A document may serve several targets, and a target may contain many claims.

The register presently normalizes:

- 22 core frontier targets;
- 14 legacy multi-branch research lanes;
- eight external validation phenomena;
- eight explicitly speculative missing-middle arcs;
- two terminal torsion-flavour new-physics gates; and
- the current AZ-032--AZ-057 execution, bridge, literature and re-ranking sequence.

The detector extension additionally normalizes:

- 20 frontier regions;
- 37 detector bundles; and
- 50 maintained topics: 45 live across active, open, audit, gated and blocked states, plus five closed with retained evidence.

The full-corpus census presently hashes and inventories all 3,264 in-scope Markdown/JSON artifacts across `corpus/` and the evidence ledger, including 1,575 numbered claims and 960 evidence artifacts. It reconciles 1,909 files containing the expanded gate vocabulary or an open-like structured status, including 1,176 claims and 182 evidence records; the other 399 claims are explicitly recorded as having no declared gate. It reports zero unmatched ownership records. This is a lexical, structured-status and governance exhaustion result, not a claim that every tacit scientific question has been discovered or solved.

Speculative entries remain visible but carry zero evidential weight. Crosswalk membership indicates relevance, not proof of a physical identification.
