Annaprasana source profile

What this implementation claims

The configured first-feeding profile is based on B. V. Raman, Muhurtha (Electional Astrology), Chapter VIII, “Post-natal ceremonies” / “First feeding on rice (Annaprasana),” internal printed pages 22–23 (physical PDF pages 25–26) in the inspected 2020 Chistabo derivative. Its “usual unfavorable Tithis” reference is resolved through the same book's general Panchanga Suddhi list in Chapter V, internal printed page 12 (physical PDF page 15):

inspected 2020 Chistabo derivative

The Drik browser path implements six Annaprasana-specific election-chart clauses from the public B. V. Raman transcription identified below. A complete result means only that those six clauses were evaluated across every represented state of the candidate window. It does not close the general election-chart baseline tracked in issue #284, and it is not a universal electional verdict.

Python and MCP return the Panchangam shortlist and the original source-guidance rows. They do not request candidate-time charts. MCP therefore labels the exact assessor drik_browser_only and the general baseline open_issue_284.

Artifact identity and authority

The public file used here is B. V. Raman, Muhurta, a 78-page Chistabo derivative uploaded in 2020. Its physical PDF page 3 says it was re-edited, that additions were placed in brackets, and that the appendix was omitted. It is therefore registered as BVR-MUHURTHA-CHISTABO-2020, the directly inspected derivative. The related BVR-MUHURTHA-1993 record preserves the 181-page UBS work's Google Books and Open Library bibliographic identity, but that edition was not inspected. Located Raman claims cite both IDs: the UBS ID identifies the work while the Chistabo artifact supplies the visible wording and page locator. The registry does not claim that the derivative is the UBS edition.

The Annaprasana profile occupies Chapter VIII, internal printed pages 22–23 (physical PDF pages 25–26). All six chart clauses occur together on internal printed page 22 / physical PDF page 25. The Chapter V cross-reference for the general Panchanga-Suddhi Tithis is internal printed page 12 / physical PDF page 15.

Profile-to-code crosswalk

Source criterion	Implementation	Product treatment
6th, 8th, 9th or 12th month	original manual information row	Disclosed because the search does not take the child's age-month as input.
Twelve named Nakshatras	allowed_nakshatras	Conservative Panchangam admission gate.
General unfavorable Tithis	avoid_tithi_numbers	Chapter V cross-reference; 4, 6, 8, 12, 14 and both terminal lunar days, represented as 15.
Monday, Wednesday, Thursday and Friday	allowed_varas	Other weekdays reject the day.
Mesha, Vrischika and Meena rising are unfavorable	allowed_lagnas	The other nine Rasis form the slot-time admission set.

The shared samskara exclusions, Choghadiya and Tithi-family weights, personal scoring and relative tiers are project rules. They do not inherit authority from the Annaprasana paragraph.

Six-clause chart contract

All six rows use claim muhurta.annaprasana.raman_transcription_chart and the exact locator “B. V. Raman, Chapter VIII, ‘First feeding on rice (Annaprasana),’ inspected in the 2020 Chistabo derivative at internal printed p. 22 (physical PDF p. 25).”

Rule ID	Source wording represented	Effect
annaprasana.house-10-vacant	Leave the 10th unoccupied	Mandatory: any known failure removes the slot.
annaprasana.budha-not-7	Budha is outside the 7th	Mandatory.
annaprasana.kuja-not-8	Mangala is outside the 8th	Mandatory.
annaprasana.shukra-not-9	Shukra is outside the 9th	Mandatory.
annaprasana.benefic-occupies-lagna	Budha, Guru or Shukra in Lagna is commended	Preference only. Absence does not reject, change score or cap the rating; a fully resolved pass breaks ties.
annaprasana.no-natural-malefic-in-lagna	No natural malefic in Lagna	Mandatory under the separately disclosed classification below.

“In Lagna” means physical occupation of Whole Sign house 1. The assessor does not import the Namakarana passage's different “strengthen Lagna” instruction, nor does it turn aspect, lordship or an undisclosed strength score into occupation.

Engineering conventions, kept separate from the text

Whole Sign occupation

Using the validated local Drik/Lahiri Lagna Rasi, every returned graha is projected locally:

house(graha) = 1 + ((RasiIndex(graha) - RasiIndex(Lagna) + 12) mod 12)

All nine returned grahas count for vacancy. This is election_chart.whole_sign_house_policy_v1, not a quotation from Raman.

Natural-malefic set and node choice

The fixed set is Surya, Mangala, Shani, Rahu and Ketu. Chandra joins the set only when classified as waning below. The enumeration has a modern supporting witness in the Enjoy Learning Sanskrit rendering of BPHS 3.11. That page is registered as a modern_text_witness, not a critical edition.

Rahu and Ketu use the sidecar's explicitly returned mean-node convention. Choosing mean nodes is election_chart.mean_node_policy_v1, a product convention.

BPHS 3.11 also conditions Budha on association with a malefic. This version limits “association” to same-sign occupation. It creates no second Budha failure: the accompanying fixed natural malefic already fails the same Lagna prohibition. Aspect, dispositor and lordship associations are not inferred. That boundary is election_chart.budha_same_sign_association_policy_v1.

Waxing and waning Chandra

Raman Chapter II, internal printed page 4 / physical PDF page 7, describes Chandra as waxing below 180 degrees of longitude difference from Surya and waning above 180 degrees. The implementation makes the arithmetic explicit:

E = (longitude(Chandra) - longitude(Surya)) mod 360
0 < E < 180       => waxing
180 < E < 360     => waning

If Chandra occupies Lagna, waxing passes this one prohibition and waning fails. Because the chart contract reports two-decimal degrees and the source does not classify exact conjunction/opposition, E at or within 0.02° of 0° or 180° returns unknown. The split and boundary guard are separately registered as election_chart.raman_180_degree_paksha_policy_v1 and election_chart.lunar_phase_boundary_guard_policy_v1.

Sample aggregation and fail-closed behavior

Each window is checked at its represented start, final minute, ten-minute cadence points, and both sides of every known interior local Lagna transition.

For a mandatory rule:

any fail => fail
else any unknown => unknown
else => pass

For the positive Lagna preference, every sample must pass to earn the preference; all-fail is a resolved preference miss; mixed pass/fail or any unknown is unknown. A fixed natural-malefic failure in Lagna controls even if Chandra simultaneously lies on a phase boundary. Missing, duplicate or invalid chart facts fail closed. These are product decisions recorded under election_chart.annaprasana_fail_closed_aggregation_policy_v1.

Material source disagreement

The implemented policy is explicitly election_chart.annaprasana.raman_transcription_policy_v1; it does not merge conflicting lists. This is an engineering-policy claim with no direct source IDs. It depends on the separately registered textual claims muhurta.annaprasana.raman_transcription_chart and muhurta.annaprasana.source_divergence, which carry the external source IDs and exact artifact/page locators.

Witness	Exact locator	Visible difference
N. P. Subramania Iyer, Kalaprakasika, first English publication 1917; AES reprint 1982	Chapter III, “To Feed on Rice,” printed p. 34 (public PDF p. 66; OCR lines 3305–3317)	Places Shukra outside the 7th and Budha outside the 9th, reversing Raman's Budha-7/Shukra-9 assignment.
Rama Daivajna, Muhurta Chintamani with Piyushadhara commentary, Nirnaya Sagar Press, 5th ed., 1945	Samskara-prakarana verse 18, printed p. 178 (scan p. 194); commentary printed p. 180 (scan pp. 196–197)	The verse places Chandra outside houses 1, 6 and 8. The commentary qualifies Lagna adversity as weak or waning Chandra and describes full Chandra in Lagna as favorable. This is not silently simplified to “Moon in Lagna is always prohibited.”

Those differences are machine-registered as muhurta.annaprasana.source_divergence with state contradicted. A future source-selectable assessor would need its own policy and tests; it must not quietly change this version.

What the result states

• A hard failure removes the candidate and the UI lists the failed rule plus observed chart fact.
• A missing Lagna-benefic commendation is shown as “Preference not present · no penalty.”
• A supported unknown retains the candidate, caps an otherwise Excellent rating at Good, and says review is still needed.
• Only an unbounded, fully resolved Drik run may say “Annaprasana event-specific chart assessment complete.” Every such result also says the general election-chart baseline #284 remains open.

The source IDs, claims, locators and convention scopes are canonical in provenance.json. The generated all-prerequisite crosswalk is muhurtam-rule-crosswalk.json, and the shared Python/TypeScript behavior oracle is tests/fixtures/election_chart_annaprasana_oracle.json. That oracle combines synthetic clause-isolation cases with two frozen DashaFlow 1.1.0/Lahiri geographic projections: Hyderabad on 2026-01-15 and Sydney on 2026-05-28, retrieved on 2026-08-30. Both language implementations also recompute and assert every Whole Sign house from the returned Rasi and the recorded local Lagna rather than trusting a sidecar house number.
