# Source and implementation notice

All interpretation code, UI code, test code and explanatory prose in this prototype are independently authored for this task. No Horosa runtime function, component, modern prose, commentary corpus or no-license supplemental note has been copied into it. It adds no new runtime dependency.

The separate Horosa checkout at revision `daab60ce05c8f0e78cc51b5e7974120f81aed79c` was inspected for **behavioral scope only**. That reference project is AGPL-3.0-only; its license is not treated as permission to paste its runtime into this independent implementation. Its seven selectors establish a UI contract, not seven separate pillar engines and not proof that every school has a universally agreed formal specification. The alternate 日柱主/年月时宾 setting permits factual comparison with that contract; the implementation is a newly written, position-specific graph.

The classical works below are historical public-domain texts. This implementation transcribes small symbolic rule facts and writes new neutral explanations; it does not reproduce their paragraphs, website editorial material or modern annotations. Website hosting/editorial licenses do not become a license for copying their non-public-domain material. The texts' historical assertions about people, wealth, sex, illness, lifespan or family outcomes are expressly not implemented.

1. 《子平真诠》论用神: https://www.donglishuzhai.net/chapter/3721.html
   - Month-command pattern candidates and distinct 顺/逆取用 questions.
2. 《子平真诠》论用神成败救应: https://www.donglishuzhai.net/chapter/3722.html
   - Officer/seal/wealth/output/kill configurations, constraints and rescue paths. The prose retains the unmet strength, location and root premises rather than deleting them and asserting success.
3. 《子平真诠》论用神变化: https://www.donglishuzhai.net/chapter/3723.html
   - Branch qi and exposed stems; multi-candidate handling is explicitly this prototype's bounded policy.
4. 《穷通宝鉴》 reviewed witness, fixed revision 2294674:
   https://zh.wikisource.org/w/index.php?title=穷通宝鉴&oldid=2294674
   - 114 direct base clauses and 5 conditional cells. All 10 stems and 12 months were inspected in this same witness. `tiaohou-catalog.json` lists each included cell, primary/secondary symbolic checklist, section title and original implementation note.
   - The witness lacks a distinct 乙丑 paragraph and repeats an eleventh-month 乙 paragraph. This prototype does not silently borrow a modern table or another edition.
   - 甲辰: ordinary 庚/壬; 丁 requires the text's 金局 condition. The prototype checks 金三合/三会 complete shapes but explicitly does not prove成局/成化.
   - 甲未: 丁 then 庚 in this witness, not a copied generic summer table.
   - 秋己: 癸 then 丙; 辛 can assist 癸, with 甲 additionally discussed for 戌. This differs from some contemporary lookup tables.
   - 乙午, 乙酉, 癸辰 have exact named-term branches. The helper reads their library solar-term instants, with a declared inclusive later-boundary convention.
   - 丙亥 and 丁午 have conditional overall configurations; no invented numeric thresholds resolve them.
5. 《三命通会》卷一: https://zh.wikisource.org/zh-hans/三命通會/卷一
   - Nayin names/pairs; bounded named-class conditions for 天河水, 剑锋金, 覆灯火, 炉中火, 钗钏金. The text itself distinguishes special names from generic 生克.
6. 《三命通会》卷二: https://zh.wikisource.org/zh-hans/三命通會/卷二
   - 年本/日主 comparison, ordinary 合/冲 structures. A mere relationship shape is not made into a claim of harm or success.

Existing MIT `lunar-javascript` is reused by the host, tests and optional calendar adapter. No library code is vendored into this package. All 60 Nayin values are independently cross-checked against its installed table. Retain the Site's existing lunar license notices. The calendar adapter accepts the already-calculated Lunar object; it never installs or retrieves calendar code.

## Independently declared working conventions

The three-column 扶抑 convergence test, same-element/exact-stem root switch, cautious multi-candidate pattern selection, conflict evidence grammar, positional 宾主体用 graph, method comparison and all modern neutral explanations are **this implementation's working definitions**, not the claimed verbatim formulas of a classical author. No percentage, energy weight, odds, empirical validation or scientific confidence is implied.

The graph defaults to 日时主/年月宾 and has a 日主/年月时宾 comparison switch. 体 includes 比劫、印、食神 and the day master; 用 includes 财、官杀、伤官. These are disclosed graph categories, not a complete or universally valid 盲派 transmission. Do not market this package as full 盲派做功、全本神峰病药 or complete ancient Nayin parity.
