3.6. Structural validation🔗

analyze checks:

• reversed intervals;

• duplicate indices;

• missing or non-earlier parents;

• incorrect root or child depths;

• same-thread children outside their parent interval;

• overlapping immediate siblings on one thread.

Analysis continues after a problem so the trace remains inspectable. A report with issues is diagnostic data. The strict summary reader rejects missing fields, unknown fields, non-integer nanoseconds, duplicate keys, inconsistent totals, and malformed retained-index prefixes.
