basis needs you to decide
These have the shape of a corporate action, but nothing basis could check confirms one. It will not guess, because guessing wrong here puts a wrong cost basis on every share you own.

AAPL
QUANTITY_MISMATCH
confirmed
Your broker reports 80, basis computed 20.
UNAPPLIED_SPLIT
The broker reports 4 for 1 of what basis computed, and AAPL had a 4 for 1 split effective 2020-08-31 that this history never applied.
Apply the 4 for 1 split of AAPL dated 2020-08-31 and reconcile again.
VTSAX
QUANTITY_MISMATCH
suspected
Your broker reports 4, basis computed 12.
RATIO_WITHOUT_KNOWN_SPLIT
The broker reports 1 for 3 of what basis computed, which is the shape of an unapplied reverse split, but the split history for VTSAX was confirmed on 1970-01-01T00:00:00Z and contains no such split between 2023-01-09 and 2026-09-02. The ratio is a coincidence.
Treat this as missing trades rather than a corporate action, and look for activity the imported history does not contain.
MSFT
BASIS_MISMATCH
suspected
Your broker reports 40, basis computed 40.
BASIS_DRIFT
The share count agrees but the cost does not: the broker says 9800.00 USD and basis computed 8800.00 USD, a difference of 1000.00 USD.
Check whether commissions were capitalised into basis, or whether a corporate action reallocated basis differently.
TSLA
UNKNOWN_TO_LEDGER
suspected
Your broker reports 15, basis computed 0.
UNKNOWN_HOLDING
The broker reports 15 TSLA and the imported history contains no acquisition of it at all.
The statement covering the purchase is probably missing, or this security was renamed and the mapping file does not know about it yet. It is also exactly 0.75 per share of the 20 AAPL already held, so if AAPL spun off TSLA, apply the spin off with the basis fraction from the company's Form 8937. That ratio on its own is not evidence: unrelated holdings divide cleanly all the time, and basis will not guess which of the two happened.
