Stellar Heliacal Candidate Source Ledger (2026-04-09)

Purpose:

• provide the concrete intake ledger for stellar heliacal validation sources
• keep source discovery separate from source admission
• ensure every candidate source is captured with enough metadata to judge whether it can become an oracle

Upstream documents:

Current status:

• partially populated intake ledger
• no new non-Sirius external source admitted yet

Intake Rules

Do not admit a source into validation simply because it mentions a heliacal rising.

A candidate source must be captured first, then judged against:

• provenance
• explicit event semantics
• observer/location specificity
• calendrical clarity
• visibility-criterion transparency

Candidate Table

Candidate ID	Star	Source title / citation	Source kind	Event kind	Site / latitude	Date or range	Criterion stated?	Oracle tier	Admission status	Notes
SHS-001	Sirius	Censorinus / Sothic anchor lineage	historical anchor	heliacal rising	Alexandria band / Egyptian context	139 AD anchor slice	partial	Tier A	admitted_anchor	Current governing stellar anchor in Moira.
SHS-002	Sirius	Bradley E. Schaefer, “The Heliacal Rise of Sirius and Ancient Egyptian Chronology” (2000)	scholarly historical reconstruction	heliacal rising	Alexandria / Egyptian chronology context	139 AD-centered historical discussion	yes	Tier A	admitted_secondary	Admissible as secondary scholarly support for the existing Sirius anchor; still not a new non-Sirius corpus row.
SHS-003	multi-star / general	Bradley E. Schaefer, “Heliacal Rise Phenomena” (1987)	scholarly methodology paper	heliacal rising / setting family	general methodological scope	general	yes	Tier A	admitted_secondary	Admissible as methodology and criterion-law support only; not by itself a star/date oracle row.
SHS-004	TBD non-Sirius bright star	candidate source not yet captured	TBD	TBD	TBD	TBD	TBD	Tier A or B	candidate_needed	First non-Sirius bright-star candidate with explicit event semantics still needed.
SHS-005	TBD non-Sirius bright star	candidate source not yet captured	TBD	TBD	TBD	TBD	TBD	Tier A or B	candidate_needed	Second bright-star candidate with different declination geometry still needed.
SHS-006	TBD	candidate historical reconstruction source not yet captured	scholarly reconstruction	TBD	TBD	TBD	TBD	Tier A	candidate_needed	Reserve slot for a non-Sirius historical reconstruction source.
SHS-007	TBD	candidate modern observational-study source not yet captured	observational study	TBD	TBD	TBD	TBD	Tier A or B	candidate_needed	Reserve slot for a modern stellar visibility study with usable row data.

Admission Status Meanings

• admitted_anchor already admitted as a governing validation anchor
• candidate_needed slot intentionally reserved; no source captured yet
• captured_pending_review source is identified but not yet judged admissible
• admitted_secondary admissible as a secondary oracle or corpus member
• rejected source reviewed and explicitly excluded

Required Review Questions

For each future captured source:

1. Does it identify a specific star unambiguously?
2. Does it specify first visibility, last visibility, or another event family explicitly?
3. Does it provide a site, latitude, or region precise enough to model?
4. Does it provide a date, year, or constrained date range?
5. Does it state or imply an observational criterion clearly enough to compare against Moira policy?
6. Is it primary, scholarly secondary, or merely convenience commentary?
7. If historical, how much calendrical reconstruction uncertainty is present?

If those questions cannot be answered, the source should not become part of the admitted validation corpus.

Immediate Next Fill Targets

The first useful additions to this ledger should be:

1. capture one non-Sirius historically prominent bright-star source
2. capture one source family from modern observational visibility literature
3. convert the first admissible non-Sirius source into a row in the stellar case ledger
4. keep SHS-002 and SHS-003 as secondary support rather than treating them as broad closure

Current Captured Scholarly Candidates

Already captured in this ledger:

• Bradley E. Schaefer, Heliacal Rise Phenomena (1987)
• Bradley E. Schaefer, The Heliacal Rise of Sirius and Ancient Egyptian Chronology (2000)

These now have the following status:

• SHS-002: admitted as secondary scholarly support for the Sirius anchor
• SHS-003: admitted as secondary methodology support

Neither source closes the non-Sirius corpus gap by itself.

Current Honest State

Right now, Sirius remains the only clearly admitted stellar heliacal validation anchor.

Moira now also has two explicitly admitted secondary scholarly supports for that anchor and for stellar-heliacal methodology, but still lacks an admitted non-Sirius external validation row.

This ledger exists so future expansion happens under provenance discipline rather than ad hoc reference gathering.
