A data directory written by v0.15.0 or earlier can hold a valid key next
to the activation token of another license, typically a refunded hence
revoked one. The License card read "Activated", market prices were
refused, and "Activate" was never offered: the folder could not recover
without a manual file removal.
- Prices: a 403 license_revoked drops the refused token, and only while
the file still holds it, so an activation that lands while the refused
request is in flight keeps its new token (CWE-367). The key's revoked
state is never written from this route. The token is read through
ACTIVATION_FILE by the directory-based read_stored_activation_token_in,
in fetch_price_in, testable without AppHandle.
- Machine list: list_activated_machines returns { machines,
token_dropped }. A complete list that names this machine under neither
identifier drops a token that activates this machine, when the OS id is
readable and the token is the one on disk when the list was asked for.
An error, a revoked key or a rate limit drops nothing.
machines_from_verify counts the rows it skips, which the list still
tolerates. This also gives "Activate" back to a machine deactivated from
another computer.
- Front: the activation status is read again after every list load; a
fixed log line (ACTIVATION_TOKEN_LOG) is written on token_dropped and on
a price refused as revoked; the revoked-license price message invites to
activate the machine again.

guide and in-app tips, changelogs.
