Vedic (Jyotish) - Phased Build Plan (v1)

Jeff's call (2026-06-16): part now, part later; the corpus is weak on Vedic; keep this logged. This is the plan. Parashara (the council's Vedic voice) sits on top of this engine once it exists.

Guardrails unchanged: chart-driven only, Tier C benchmark-only (computation is ours), no em dashes, no prediction/guarantee/fatalism, no medical or financial advice, locked demo untouched, script-only until Jeff approves a render.

PART NOW - DONE (2026-06-16)

Lightweight sidereal facts that let Vedic speak inside the SYNERGIES, not as a separate reading. - affirmology-agent/src/affirmology/chart/vedic.py: derives the Lahiri sidereal layer from the chart's already-computed tropical longitudes (no new geocode, no new deps): sidereal rashis for Sun/Moon/Ascendant, Moon nakshatra + pada + Vimshottari lord, gana, nadi. - Wired into council.sophia_brief() so Sophia can confirm or complicate a cross-system convergence with the sidereal sky. - Verified facts: Jeff sidereal Sun Leo, Moon Gemini/Ardra (Rahu); Sol sidereal Sun Capricorn, Moon Gemini/Ardra (Rahu). Synergy surfaced: both founders share a sidereal Ardra Moon, reinforcing the shared tropical Cancer Moon. - This is intentionally shallow. It is enough to participate in synthesis, not a full reading.

PART LATER - PHASED (heavy, sequence TBD with Jeff)

• L1, Vimshottari dasha (small-to-moderate). Current mahadasha and antardasha from the Moon's nakshatra + exact birth JD (we already store UTC datetime). Gives the "what life-chapter is running" layer. Lets Vedic speak to TIMING alongside transits.
• L2, divisional charts + yogas (heavy). At least D9 Navamsa (marriage/dharma, and it dignifies or weakens D1 placements), optionally D10 for vocation. Plus core yogas (Raja, Dhana, Gajakesari, etc.). This needs careful classical rules and rigorous verification. Highest effort, highest risk of subtle error.
• L3, Vedic corpus (REQUIRED before Vedic-led generation). Our corpus is weak on Jyotish: nakshatra, dasha, and yoga interpretations. Strengthen A/B-tier Vedic sources first. Note licensing: classical texts (e.g., BPHS) and Jovian-style sources need the same tier discipline; lean on reputable community A/B explanations, keep classical/proprietary as Tier C benchmark-only.
• L4, Parashara + Vedic audio paths. Parashara becomes a full council voice on this data, and we add dedicated Vedic structures/audio paths (the "custom audio paths" Jeff mentioned), not just synergy mentions.

VERIFICATION DISCIPLINE (do not skip)

Like Human Design is fixture-tested against Josh's MyBodyGraph report, every Vedic phase must be verified against a KNOWN Vedic chart oracle: - Pick a public or hand-verified Jyotish chart as a fixture (sidereal positions, Moon nakshatra/pada, current dasha, D9) from a reputable Vedic source. - Cross-check our four founders against a trusted Vedic calculator and store the expected values in known_charts.py style fixtures. - No Vedic output ships in reports or audio until the fixtures pass. Accuracy is the floor.

STATUS / NEXT

• Now: synergy-level Vedic is live in synthesis. No Vedic-led audio yet.
• Next on the main queue is Affirmology_StudioChangeList_v1.md P0.2 (iterative composer); Vedic L1-L4 are scheduled around that per Jeff.
• Updates will be logged here, in PROJECT_STATE section 13, and in the change list, so every chat stays in sync.
