In @.github/aiv-packets/PACKET_task_8_9_data_safety.md:
- Around line 5-7: The identification table's "Repository" entry is incorrect
(currently "github.com/ImmortalDemonGod/aiv-protocol"); update the table row so
the Value for the **Repository** Field reads
"github.com/ImmortalDemonGod/flashcore" instead, ensuring the pipe-delimited
markdown table (the row with | **Repository** | ...) is replaced with the
correct repository name.
In `@flashcore/scripts/migrate.py`:
- Line 23: The file imports Optional from typing but never uses it; remove the
unused import by deleting Optional from the import statement (i.e., change "from
typing import Optional" to remove Optional or remove the entire line if no other
typing imports are needed) so the module has no unused imports and linter
warnings are resolved.
- Around line 50-54: The _coerce helper is dead code; either delete the unused
_coerce() or incorporate its empty-string→None behavior into the existing
_row_tuple() logic. If you remove it, simply delete the _coerce definition; if
you integrate it, update _row_tuple() to call the coercion (or replicate the
logic) for each field when nullable behavior is required so empty strings become
None, and remove the unused _coerce() afterwards.

Dead code: _coerce() is defined but never called.
This helper function for converting empty strings to None is never used anywhere in the module. Either remove it or integrate it into _row_tuple() if the behavior is needed.

- Around line 110-119: The function _insert_sessions currently returns len(data)
which counts attempted inserts, not actual rows inserted when using INSERT OR
IGNORE; change it to capture the connection's change count before and after
executing the batch (use conn.total_changes), call conn.executemany(sql, data),
then compute and return the delta (after - before) so _insert_sessions returns
the actual number of rows inserted; reference symbols: _insert_sessions,
_SESSIONS_COLUMNS, _row_tuple, conn.executemany, conn.total_changes.
- Around line 82-85: The helper _row_tuple currently maps missing keys to None
which can hide missing/invalid JSON fields; change it to validate presence of
every required column and fail fast: in _row_tuple, iterate over the provided
columns and if any column is not present in the row dict (or explicitly missing
in the JSON payload), raise a clear exception (e.g., ValueError or KeyError)
listing the missing column(s) and the offending row; otherwise return the
ordered tuple of values. Ensure the exception message references the column
names and the row content to aid debugging.

Prevent silent NULL injection for missing JSON fields.
Line 84 silently maps missing keys to None. In a migration tool, this can hide schema/key mismatches and cause silent data loss (or late constraint failures) instead of failing fast with actionable errors.

currently maps missing keys to None which can hide missing/invalid JSON fields;
change it to validate presence of every required column and fail fast: in
_row_tuple, iterate over the provided columns and if any column is not present
in the row dict (or explicitly missing in the JSON payload), raise a clear
exception (e.g., ValueError or KeyError) listing the missing column(s) and the
offending row; otherwise return the ordered tuple of values. Ensure the
exception message references the column names and the row content to aid
debugging.

Return actual inserted session rows, not attempted rows.
With INSERT OR IGNORE, Line 119 can over-report inserted rows when duplicates are ignored.
