Wii U decompilation of all 6 callers of snj_stage_create confirms
the field distinguishes new stage creation (1) from entering an
existing stage (2): lobby/myhouse/quest pass 1, guild room and
move operations pass 2.
Verified via Wii U decompilation of putUpdate_house: the field is set
to 0 when no password is provided, and 1 when a password string is
present. The previous comment "Always 0x01" was inaccurate.
Add package-level documentation (doc.go) to all 22 first-party
packages and godoc comments to ~150 previously undocumented
exported symbols across common/, network/, and server/.
Fix unchecked error returns on bf.Seek(), db.Exec(), QueryRow().Scan(),
pkt.Build(), logger.Sync(), and binary.Write() calls. The linter now
passes with 0 errors, build compiles, and all tests pass with -race.
Re-enable the golangci-lint job in CI (disabled Oct 2025), update to
Go 1.25 and golangci-lint-action v7. Fix errcheck, gosimple S1009,
staticcheck SA4031 and SA2001 errors across 54 files. Remaining ~39
lint errors will be addressed in follow-up commits.
Move time utilities (TimeAdjusted, TimeMidnight, TimeWeekStart, TimeWeekNext,
TimeGameAbsolute) from channelserver into common/gametime to break the
inappropriate dependency where signserver, entranceserver, and api imported
the 38K-line channelserver package just for time functions.
Replace all fmt.Printf debug logging in sys_session.go and handlers_object.go
with structured zap logging for consistent observability.
Import 18 network packet test files and 5 server infrastructure test
files, adapted for main branch APIs: fix config import alias (_config),
remove non-existent DevMode field, use global handlerTable instead of
per-server handlers map, and correct validateToken mock expectations
to include both token and tokenID arguments.
Adds go-sqlmock dependency for database mocking in signserver tests.
