Add 30 new tests to handlers_commands_test.go covering previously
untested paths: raviente with semaphore (start, multiplier, ZZ-only
sed/res commands, version gating), course enable/disable/locked/alias,
reload with other players and objects, help filtering for non-op vs op,
ban error paths and long-form duration aliases, and disabled-command
gating for all 12 commands. Total: 62 tests, all passing with -race.
The guild daily RP rollover TODO in handlers_guild_ops.go was stale —
the feature was already implemented via lazy rollover in
handlers_guild.go. Several other items in technical-debt.md were also
resolved in prior commits (typos, db guard investigation). Updated
the doc to reflect current state and bumped codecov-action to v5.
Add SJISToUTF8Lossy() that wraps SJISToUTF8() and logs decode errors at
slog.Debug level. Replace all 31 call sites across 17 files that previously
discarded the error with `_, _ =`. This makes garbled text from malformed
SJIS client data debuggable without adding noise at default log levels.
Replace db.Begin() with db.BeginTxx(context.Background(), nil) across all
8 remaining call sites in repo_guild.go, repo_guild_rp.go, repo_festa.go,
and repo_event.go. Use deferred Rollback() instead of explicit rollback
at each error return, eliminating 15 manual rollback calls.
Players could never claim monthly guild items because the handler
always returned 0x01 (claimed). Now tracks per-character per-type
(standard/HLC/EXC) claim timestamps in the stamps table, comparing
against the current month boundary to determine claim eligibility.
Adds MonthStart() to gametime, extends StampRepo with
GetMonthlyClaimed/SetMonthlyClaimed, and includes schema migration
31-monthly-items.sql.
fmt.Sprintf inside zap logger calls defeats structured logging,
making log aggregation and filtering harder. All 6 sites now use
proper zap fields (zap.Uint32, zap.Uint8, zap.String).
LoopDelay had no viper.SetDefault, so omitting it from config.json
caused a zero-value (0 ms) busy-loop in the recv loop. Default is
now 50 ms, matching config.example.json.
