}

Why a history source (a transcript file, a history database) was not read. Typed and content-free: no path, no byte of the source.

Variants

OutsideRoot

It does not resolve inside any named root (symlinks resolved).

Withheld

A path rule, the project policy or the gateway withholds it, or it is delivered for a reader only and may not feed a store (E3).

TooLarge

It is larger than the total cap of its kind (bounded::MAX_TRANSCRIPT_BYTES, database::MAX_HISTORY_DATABASE_BYTES; the read cap for a single JSON document, which is one record). A source is never read in part.

RecordTooLarge

One record of a transcript is larger than the per-record bound (the read cap). A record is never cut and never passed uninspected, so the transcript is not imported.

UnitAdmissionUnsupported

A transcript above the read cap cannot be admitted piece by piece without being judged more weakly than as a whole: a rule that is active now can match across lines without a bound (a policy-pack or configured pattern not proven single-line, a semantic detector), or a piece ends inside such a match of a built-in rule. It is not read — as it was not before transcripts above the cap were read at all.

TooManyFacts

One transcript or database yields more distinct facts than may be held pending until it is read to its end (staging::MAX_PENDING_BYTES). It is not imported in part.

Changed

It is no longer the file that was verified, or it was written while it was read: exchanged at its path, or changed in size or time.

Unreadable

It cannot be read as text (missing, binary, I/O error).

DatabaseUnreadable

A verified database that the engine cannot open, or whose rows cannot be stepped or decoded to their end. It is not imported in part.

UnsupportedSchema

A database without the tables and columns its importer reads.
