Zodiacal Releasing

Zodiacal releasing (Valens, Anthology IV) walks the signs in order from the released lot's sign, the Lot of Spirit by default, each sign lasting its planetary years. Each deeper level divides the unit by twelve and starts again from its parent's sign, so a chapter of years holds months, a month holds 2.5-day units, and those hold 5-hour units. When the children of a long period complete a full circuit of the zodiac, the sequence jumps to the sign opposite the parent: the loosing of the bond. Periods whose sign is angular to the Lot of Fortune's are marked, the tenth being the peak.

Ask for one instant to get the period in force at each level, or for a range to get every period overlapping it as flat records, ready for a timeline.

Parameters

The walk

A year is 360 days, fixed, which is what makes the nesting exact: a chapter of N years is exactly 12N months. Inside a period of sign S the next level begins from S and proceeds in order, each child lasting its own count of the smaller unit, the last child cut to the parent's end.

Loosing of the bond. The twelve signs total 211 units, so a parent of 18 years or more (Gemini, Cancer, Leo, Virgo, Capricorn, Aquarius) outlasts one full circuit of its children. When they have completed all twelve signs, at exactly unit 211, the next child does not return to S but begins at the sign opposite the parent and continues from there. That child carries loosing_of_bond. No parent is long enough for a second loosing. The top level has no parent and simply continues around the zodiac.

Angularity from Fortune. A period whose sign is the 1st, 4th, 7th, or 10th from the Lot of Fortune's sign, counted inclusively, is angular to Fortune, and the 10th is the peak. angle_from_fortune carries the count so the four are distinguishable. Without a Lot of Fortune in the chart (no Moon among bodies) the flag is unset on every period and warnings says so.

Range caps. The deeper the level the shorter the units, so the range a request may cover shrinks with max_level: 120 years at levels 1 and 2, 10 years at level 3, one year at level 4. A ten-day request at level 4 does not compute a lifetime; generation covers only the periods overlapping the range.

Nothing precedes birth. A range that begins earlier is cut to the birth instant, unflagged. An at before birth returns 400.

Records are flat, ordered by start then level, so a renderer draws one track per level and recovers the nesting from time containment. An at query returns one whole period per level, never clamped.
