# QUINCUNX first registered test — data, registration and audit record (v4)

Machine-readable warrant for the paper "QUINCUNX: A Discovery Engine for the World's
Sparse Domains, & Where They Join" (concept DOI, all versions: 10.5281/zenodo.21878807). This package:
DOI 10.5281/zenodo.21878846. The prose paper makes the argument;
this package preserves the evidentiary chronology. All timestamps are carried by the
project's version-controlled record; the key registration commits are listed below.

## Contents
- registration/ — the frozen pre-reveal objects: the sixteen quantitative predictions
  with 90% intervals and per-target methods (frozen_predictions_blockB.json, sealed
  commit f9f204a, 6 Aug 2026 09:34 UTC, before any holdout fetch); the interval target
  registry; the EDR rival-battery test bundle INCLUDING its dated amendment ledger
  (rows A1–A9: every post-freeze choice, dated, with its blind/outcome status); the
  corrected-instrument validation frames (registered before any label existed) and the
  closed fix ledger.
- reveal/ — the holdout scoring record (all sixteen actuals, coverage flags,
  per-target distances; countersigned 6 Aug).
- battery/ — the EDR rival battery's original (alpha) machine results and emitted
  verdicts (single blind execution, 9 Aug).
- replication/ — the corrected-instrument replication: corrected results, the
  pre-registered delta, the gold-label validation gates (computation transcript
  included), and the complete blinded coding record (both coders' labels and the
  adjudicated finals; 3,450 items).
- baselines/ — the baseline-skill registration (committed before computation) and the
  computed comparison.

## Data dictionary (abbreviated)
Prediction rows: point, interval_90pct{low,high}, evaluation_set_provinces, method.
Scoring rows: actual, interval bounds, covered, distance_to_nearest_edge.
Battery/replication verdict rows: test id, computed_quantities, threshold text,
verdict string (frozen vocabulary), d_dep grade, family_context, sensitivity results.
Gold-label rows: {proxy|edr_id|label|note}; adjudicated finals {id, final, basis}.
Labels are blinded model-adjudicated reference labels, not error-free ground truth.

## v2 additions (11 August 2026)

- `corrected_interval_diagnostic/` — the registered EDH corrected-interval
  diagnostic: registration (DESIGN_..._20260811.md), blind construction output
  (construction JSON; written before landed values were joined, seed
  QUINCUNX-EDH-CID-20260811), joined diagnostic (JSON + results note), and both
  scripts (construction, barred from reading landed values; scoring). Result:
  8/15 registered vs 11/15 corrected on the fifteen mechanically scorable targets;
  century-vector target abstained; blind 9/16 unchanged as score of record.
- `prompt/quincunx_build_prompt_v1.md` — a reusable LLM prompt for constructing a
  QUINCUNX-class engine over the reader's own found-data domain, with the caveat it
  carries on its face: the prompt encodes the contract; the user's process carries
  the discipline.

## v3 additions (11 August 2026) — completeness pass against the paper's data-record list

- `registration/edh_blockA/` — the 25 EDH conjectures: mint record (3 files + README),
  triage, pinned instruments with kill-conditions, and the registration document
  (commit f9f204a).
- `reveal/` gains the holdout ingest manifest and reconciliation record (33/33 exact),
  the machine scorer draft, and the 9/9 independent re-derivations.
- `census/` — the prospective census stream (paper §17): rung-3 registration with
  appended verdicts, pinned instruments a/b/c, and per-state validation values and
  draft entries.
- `grade_rivals/` — the Grade round's 208-rival record: dischargeability decisions,
  family-independence audit, and the full tranche packs and adjudication drafts.
- `scripts/` — the frozen executable instruments: the Block B prediction/interval
  generator, the census validation runner, the interval-defect measurement script,
  and the complete frozen EDR battery package (code, fixtures, results, tests).
- `interval_protocol/` — the interval-construction defect technical record and the
  registered v2.3 certification design.


## v4 additions (11 August 2026) — release-review pass (GPT-5.6-sol + Grok 4.5 external reviews)

Governing artifacts now included: the CIR protocol
(registration/DESIGN_QUINCUNX_CIR_PROTOCOL_20260810.md), the blind EAGLE
construction-path audit (registration/quincunx_edr_eagle_audit_20260809.md), the CIR
re-execution report and log (replication/), and the visible-half ingest record
(reveal/edh_registration_slice_ingest_20260805.md).

Census stream: close_out_summary.json makes the batch outcome machine-readable and
uses the registration's own vocabulary — 16 deaths; 24 alive = 17 holdout survivors +
1 resolved-supported + 6 registered-open (deciders not yet arrived). The paper's §17
was aligned to the same wording.

Coding record: gold_labels_coder2.jsonl re-serialized to strict JSON Lines (one
object per line, trailing newline; the 3,450 objects are unchanged — the working file
had 120 double-object lines from a transport defect). coding_frame_boundaries.json
documents the per-proxy streams (750/750/750/750/450) and the pairing rule (by id
within stream; coder batch order differs between files). validate_coding_record.py
re-derives the pairing and confirms 3,450 pairs and exactly the 232 adjudicated
disagreements (72/13/4/7/136 by stream). Run it from replication/.

Release errata: dated erratum blocks are APPENDED to four append-only records
(tranches/MANIFEST.md — a "126" transcription slip, archive holds 124+84=208;
tranche 4 — the provisional "210 minted"; the dischargeability roster's interim "-04
strengthened" parenthetical, superseded by the final table's EDH 0-of-19; the
family-independence audit — session-local paths redacted, helper scripts not
preserved). Original text above each erratum is unchanged. Note that several
append-only records begin as drafts and acquire their governing countersignature at
end of file; the final tables govern.

Scripts are the frozen instruments AS EXECUTED. The corpus-dependent ones
(scripts/derive_edh_recovery_predictions.py, scripts/run_popper_validation.py, the
edr_rivals package's DB bindings, the diagnostic's construction script) document
runs against the project's database and stack and are archival; re-running them
requires that infrastructure. Standalone from this package: replication/
validate_coding_record.py and the edr_rivals synthetic test suite
(scripts/edr_rivals/test_analyses.py, fixture-driven).

Post-review corrections (same day, after a second external review pass): the
coding_frame_boundaries.json note corrected (streams are order-aligned, records
within streams are paired by id, not position); the validator hardened (explicit
validation errors, python -O safe, checks the declared stream fields); a second
erratum on the family-independence record (the interim "172"/"56" figures);
PROVENANCE.json hashes every file except itself and now carries 23 full commit
hashes.

Also in v4: RIGHTS.md (licence and attribution), PROVENANCE.json (full commit
hashes for the registration chronology; SHA-256 and original repository path for
every file; release-modified files flagged with reasons), the build prompt's title
line corrected to the published title, and compiled-bytecode debris removed.

**Minting-model attribution (added 12 August 2026):** the r2-edh-b1 batch was minted by
Claude Fable 5 (operator attestation; see PROVENANCE.json `minting_model_attribution` —
the mint files themselves record the run but not the model name).
