Phase 4 - Sura Locks

How metrics are computed at sura level

M1 — Total letters in the sura.
M2 — Total words in the sura.
M3 — Total abjad value in the sura.
M4 — Long number built forward from verse letter counts.
M5 — Long number built forward from verse word counts.
M6 — Long number built in reverse from verse letter counts.
M7 — Long number built in reverse from verse word counts.

Data source: phase4/grand_sura_lock_summary.json — one file with per-sura records. The table lists all 114 suras for the selected mushaf and metric.

Worked Example (orientation only)

This is only a reading guide so the table is easier to understand. It is not a conclusion.

Quick example: look at Sura 1 in the table.

M1-M3 are totals for that full sura.
M4-M7 are long number forms made from the verse-level values in that sura.
If mod 19 = 0, it is shown as a sura lock.

Flow map: Phase 3 shows one verse, Phase 4 combines verses into one sura, and Phase 5 combines all suras into whole-book values.
