In-place compaction is the default. It soft-archives every earlier row of
a session under the same id (active = 0, compacted = 1), and Desktop and
the dashboard still show those turns. The md/qmd export read the session
through export_session -> get_messages with the default live-only clause,
so it wrote only the compaction summary and the carried tail.
verify_export_file then compared the file with that same dict, and
delete_session removed every row of the session, including the archived
turns that never reached the file.
The md/qmd export now reads the display history (include_compacted), for
a single session and for --lineage logical. export_session and
export_session_lineage take include_compacted, off by default:
import_sessions inserts every message as live context, so the JSON export
and stranded-session adoption keep reading live rows only.
The other transcripts people read had the same hole without the delete:
`/save md` and `/save html` (CLI and gateway), `sessions export --format
html` (one session or all of them) and `--only user-prompts` each held 1
of 6 answers on a six-turn session after one compaction. They now read
the display history too (SAVE_TRANSCRIPT_FORMATS; export_all gains
include_compacted and reads per session then, since the display read
dedupes per session). `/save json`, JSONL and the dashboard's JSON export
stay live-only for the import reason above.
Before deleting, the verify step also re-counts the store's display rows
for every session the file covers and refuses on a mismatch. A message
that lands while the files are written, or a later export change that
reads a narrower view, now refuses the delete instead of being removed
unseen. Like the adoption retire loop, the re-count runs just before
delete_session, not inside its transaction. Rewind rows (undone turns,
the superseded originals of a carried tail) are still deleted without
being exported, as `hermes sessions delete` does: they are not part of
the history the session shows.
Measured through the real CLI on a session with 6 turns and one default
in-place compaction (15 rows, 13 shown): before, 3 messages were exported
and all 15 rows deleted, with answers 1-5 missing from the file; after,
13 messages are exported in display order, then deleted.
