Subject: [PATCH 02/48] fix(gmail): default history types to messageAdded for
 backward compat

The commit 5137fcb added --history-types flag but changed the default
behavior: when not specified, it now fetched ALL history types instead
of just messageAdded (the previous hardcoded behavior).

This fix ensures backward compatibility by defaulting to messageAdded
when --history-types is not provided.

Subject: [PATCH 03/48] fix(gmail): separate deleted message IDs from fetchable
 messages

When messageDeleted history type is requested, deleted messages cannot
be fetched from Gmail API (returns 404). Now collectHistoryMessageIDs
returns a struct with separate FetchIDs and DeletedIDs lists, and the
hook payload includes deletedMessageIds field for consumers.

Subject: [PATCH 06/48] fix(gmail): resolve remaining variable shadowing lint
 warnings

Rename inner `err` to `updateErr` in two additional store.Update()
calls to avoid shadowing outer variables, completing the fix from
commit 71714ae. Both locations now match the established pattern.

Subject: [PATCH 18/48] feat(batch,csv): add --dry-run flag to preview commands
 without executing

Add --dry-run flag to batch.go and csv.go that shows which commands would be
executed without actually running them. This is important for bulk operations
to safely preview before execution.

- batch.go: Added DryRun field to BatchCmd, implements preview with
  "[dry-run] line N: cmd arg1 arg2 ..." format
- csv.go: Added DryRun field to CSVCmd, implements preview with
  "[dry-run] row N: cmd arg1 arg2 ..." format
- csv_test.go: Added TestBatchCmdDryRun and TestCSVCmdDryRun tests to verify
  dry-run mode prevents command execution

Subject: [PATCH 20/48] feat(cloudidentity): add GOG_CUSTOMER_ID environment
 variable override

Replace hardcoded cloudIdentityDefaultParent constant with a function that checks for the GOG_CUSTOMER_ID environment variable. If set, uses "customers/{value}" as the parent; otherwise falls back to "customers/my_customer". Update help text for --parent flags to document this new env var override.

Subject: [PATCH 21/48] fix(todrive): use actual first sheet name instead of
 hardcoding Sheet1

Previously, Clear() and Update() calls hardcoded "Sheet1" range regardless of the
actual first sheet name in the spreadsheet. This could cause failures when the
first sheet had a different name.

Changes:
- When creating new spreadsheets, explicitly set the first sheet title to "Data"
- When updating existing spreadsheets, fetch the first sheet name from metadata
- Use the actual sheet name (stored in sheetName variable) in Clear() and Update() calls

This ensures the code works with spreadsheets that have any first sheet name,
not just "Sheet1".

Subject: [PATCH 24/48] test(admin): add comprehensive tests for vault, roles,
 and admin groups

- Add vault tests: matters CRUD, exports, holds
- Add roles tests: get, update, delete, privileges
- Add admin groups tests: update, delete, settings, members sync
- Increases cmd package coverage from 63.1% to 65.5%

Subject: [PATCH 25/48] test(admin): add comprehensive tests for resources
 commands

Add 45 new tests for resources buildings, calendars, and features commands:
- Buildings: list, get, create, update, delete (with JSON/text output variants)
- Calendars: list, get, create, update, delete (with JSON/text output variants)
- Features: list, create, delete (with JSON/text output variants)
- Input validation tests for empty IDs and missing required fields
- Pagination and filtering tests

Subject: [PATCH 26/48] test(cmd): add comprehensive tests for alerts and
 aliases commands

Add tests for AlertsGetCmd, AlertsDeleteCmd, AlertsUndeleteCmd,
AlertsFeedbackCreateCmd, AlertsFeedbackListCmd, AlertsSettingsUpdateCmd,
AliasesCreateCmd, and AliasesDeleteCmd. Tests cover plain text output,
JSON output mode, validation errors, and confirmation requirements.

Subject: [PATCH 27/48] test(cmd): add comprehensive tests for domains commands

Add tests for DomainsGetCmd, DomainsCreateCmd, DomainsDeleteCmd,
DomainsAliasesListCmd, DomainsAliasesCreateCmd, and DomainsAliasesDeleteCmd.
Tests cover JSON and plain text output modes, error handling, missing
account validation, and confirmation requirements for destructive operations.

Subject: [PATCH 28/48] test(contacts): add comprehensive tests for contacts
 commands

Add tests for contacts delegates, domain, import, export, and dedup commands:
- ContactsDelegatesAddCmd: add delegate functionality with JSON output
- ContactsDelegatesRemoveCmd: remove delegate functionality with JSON output
- ContactsDelegatesListCmd: JSON output and empty results handling
- ContactsDomainCreateCmd: create contact with JSON output and validation
- ContactsDomainDeleteCmd: delete by resource name/email with JSON output
- ContactsDomainListCmd: JSON output and pagination
- ContactsImportCmd: CSV parsing, JSON output, and error handling
- ContactsExportCmd: CSV export to file/stdout with JSON output
- ContactsDedupCmd: duplicate detection and dry-run mode

Also includes unit tests for CSV helper functions:
- normalizeCSVHeader, parseCSVRow, csvPerson
- openCSVReader, openCSVWriter

Subject: [PATCH 29/48] test(admin): add comprehensive tests for printers and
 forms commands

Add 36 new tests for printers and forms commands:

Printers (18 tests):
- PrintersListCmd: list, JSON output, empty results, pagination
- PrintersGetCmd: get, JSON output, empty ID validation
- PrintersCreateCmd: create, JSON output, missing name/URI validation
- PrintersUpdateCmd: update, empty ID and no-updates validation
- PrintersDeleteCmd: delete, empty ID validation, confirmation check
- Helper functions: printerResourceName, printerParent

Forms (18 tests):
- FormsListCmd: list, JSON output, empty results, pagination, user filter
- FormsGetCmd: get, JSON output, empty ID validation, no-title handling
- FormsCreateCmd: create, JSON output, missing/whitespace title validation
- FormsResponsesCmd: list responses, JSON output, empty results, empty form ID, pagination

All tests use mock HTTP servers to verify API interactions.

Subject: [PATCH 33/48] test(cmd): add comprehensive tests for calendar
 commands

Add tests for calendar edit functions and event day parsing:
- applyCreateEventType with various event types and transparency settings
- parseEventTime and parseEventDate with valid and invalid inputs
- edge cases for all-day events and timezone handling

Subject: [PATCH 35/48] test(cmd): add comprehensive classroom tests

Add extensive test coverage for Google Classroom commands:
- Courses (list, get, create, update, join, leave, url)
- Coursework (list, get, create, assignees)
- Guardians and guardian invites
- Invitations (list, get, create, accept, delete)
- Announcements (list, get, create, delete)
- Materials (list, get, create, update, delete)
- Roster, students, teachers, profile

Subject: [PATCH 39/48] fix(drive): escape user values in Drive API query
 strings

Add shared EscapeDriveQueryValue to googleapi package that escapes
backslashes and single quotes, preventing query injection when
user-provided values contain those characters. Applied at all five
interpolation sites and deduplicated existing local escape helpers.

Subject: [PATCH 40/48] fix(review): address code review findings across branch

- Inline Drive query escape wrappers to use shared EscapeDriveQueryValue directly
- Add comprehensive unit tests for EscapeDriveQueryValue
- Fix CloudIdentity groups get to use UI layer instead of direct os.Stdout
- Remove duplicate splitCSVFields, use splitCSV from split_helpers.go
- Make adminCustomerID configurable via GOG_CUSTOMER_ID env var
- Add t.Parallel() safety comment to testutil_test.go
- Move cloudchannel stub from testutil_test.go to channel_test.go
- Fix batch.go channel close pattern with goroutine
- Document readValueOrFile file detection heuristic

Subject: [PATCH 43/48] feat(gmail): add signature support to send command

Add --signature, --signature-name, and --signature-file flags to append
Gmail signatures to outgoing messages. Supports fetching from Gmail
send-as settings or from a local file.

Subject: [PATCH 45/48] fix(gmail): improve HTML-to-plain signature conversion

Handle p/div/tr closing tags as line breaks, convert anchor tags to
"text (URL)" format, collapse excessive newlines, and trim trailing
whitespace. Adds table-driven unit tests covering all tag variants.
