Each customId now maps to a named handler in one of two tables:
FREE_BUTTON_HANDLERS (open-ticket panel, tag-delete cancel — no ticket
lookup) or TICKET_BUTTON_HANDLERS (anything fired inside a ticket channel
— the dispatcher does the lookup once before delegating). The dynamic
`confirm_delete_tag::*` id is matched by prefix.
To find a button's logic, search handle<Name>Button or handleTagDelete*.
Other cleanups in the same pass:
- Move findTicketForChannel and runDeferred from handlers/commands.js to
the new handlers/sharedHelpers.js so both files share one source of
truth. runDeferred now also calls logError(verb, ...) — was logged ad
hoc in buttons.js, missing in commands.js. Strictly additive.
- Hoist three inline `require('../services/...')` calls (staffThread,
pinMessage, debugLog) to top imports.
- Collapse escalate_to_tier2 and escalate_to_tier3 into one
handleEscalateButton(interaction, ticket) that derives the tier from
customId. Same for confirm_close / confirm_close_with_email /
confirm_close_no_email — one handleConfirmCloseRequest deriving
sendEmail from customId.
- Decompose the 156-line handleConfirmClose into runFinalClose +
buildTranscriptText + formatDateForTranscript + renderTranscriptHeader
+ dmTranscriptToCreator + postCloseLogEntry. Each piece is testable in
isolation.
- Decompose handleClaim into applyClaim + applyUnclaim.
- Extract buildOpenTicketModal() and postTicketWelcomeEmbeds() so the
ticket-creation modal flow is readable top-to-bottom.
No behavior change. handleButton + handleTicketModal exports preserved;
24/24 modules load clean (sharedHelpers.js is the new one).
