Major refactor: modular architecture + upstream PR features + security fixes. === ARCHITECTURE (complete rewrite) === - Split monolithic undiscord-core.js (584 lines) into 5 focused modules: - src/core/undiscord-core.js: Orchestrator (run, runBatch, stop, confirm) - src/core/search.js: Search with iterative retry (202/429 handling) - src/core/filter.js: Pure message filtering (types, pinned, bots, threads, regex) - src/core/delete.js: Delete with retry loop + rate limit adaptation - src/core/unarchive.js: Thread unarchive before delete - Split monolithic undiscord-ui.js (378 lines) into 4 modules: - src/ui/init.js: DOM mount, CSS injection, toolbar button + MutationObserver - src/ui/handlers.js: All event handlers (start, stop, getChannel, pick, etc) - src/ui/progress.js: onStart/onProgress/onStop callbacks - src/ui/logger.js: XSS-safe log rendering with ring buffer - Created src/api/discord-api.js: Pure fetch layer with AbortSignal.timeout(30s) - Split helpers.js (8 functions in 8 lines) into semantic modules: - src/utils/time.js: wait(), msToHMS() - src/utils/html.js: escapeHTML(), redact(), replaceInterpolations() - src/utils/discord.js: queryString(), ask(), toSnowflake() - Merged createElm.js + insertCss.js into src/utils/dom.js - Split CSS (theme.css 355 lines + main.css 172 lines) into 6 modules: - layout.css, components.css, scrollbar.css, redact.css, log.css, drag.css - Moved HTML templates to src/ui/html/ - Renamed utils to kebab-case (getIds -> get-ids, messagePicker -> message-picker) - Removed 12 legacy files replaced by modular architecture - Created src/utils/constants.js with shared constants === NEW FEATURES (from upstream PRs) === - victornpb#741: Poll messages (type 46) can now be deleted - victornpb#741: Bot slash command responses (type 20) excluded from deletion - victornpb#742: HTTP 403 on delete returns FAIL_SKIP instead of infinite retry loop - victornpb#743: Retry logic refactored: FAILED/FAIL_SKIP properly handled, failCount centralized - victornpb#740: HTTP 403 on search gracefully skips channel instead of canceling batch - victornpb#739: 30s delay between batch jobs to prevent API spam - victornpb#737: Thread unarchiving: attempts PATCH to unarchive before skipping - victornpb#729: Empty page retries (configurable, default 2) before stopping - victornpb#629: "Include bot/application messages" checkbox in Filter section - victornpb#610: Thread auto-detection via API when clicking "current" channel button - victornpb#603: Graceful handling of API errors 50024 (channel not found) and 50001 (missing access) - victornpb#643: Date filter warning: "Make sure you enter both date AND time" - victornpb#527/victornpb#519: Rate limit delay adds on top (never decreases) with caps === SECURITY FIXES === - S1 XSS fix: printLog now escapes all external data via escapeHTML(), preserving <x> redact tags via split pattern for streamer mode - escapeHTML() now also escapes > character - Log type validated against whitelist before becoming CSS class name - AbortSignal.timeout(30s) on ALL fetch calls (search, delete, unarchive, getChannel) replacing leaky setTimeout-based AbortController - retry_after clamped with Math.max(w, 0) to prevent negative values causing tight loops === BUG FIXES === - Fixed onStop called twice (stop() + end of run()) via guard check - Fixed missing return DELETE_RESULT.FAILED in JSON.parse catch path - Fixed filterResponse was async unnecessarily (now sync) - Fixed _searchResponse null crash with guard in filterResponse - Fixed .filter(Boolean) after map().find() to prevent undefined entries - Fixed replaceInterpolations treating falsy values (0, false, "") as missing (|| -> ??) === QUALITY IMPROVEMENTS === - DELETE_RESULT enum (Object.freeze) replaces magic strings - DELETABLE_MSG_TYPES Set replaces compound conditional - Set-based lookup for skipped messages (O(n) vs O(n^2)) - search() converted from recursive to iterative with MAX_SEARCH_RETRIES=20 - searchDelay capped at MAX_SEARCH_DELAY_MS (60s) - deleteDelay capped at MAX_DELETE_DELAY_MS (30s) - Log ring buffer: MAX_LOG_ENTRIES=5000 prevents unbounded DOM growth - Confirm preview limited to 10 messages - messagePicker timeout (30s) with automatic cleanup - drag.css selectors scoped with #undiscord - .resize-handle scoped with #undiscord - Orphan .logarea CSS class removed - MutationObserver throttle extracted to OBSERVER_THROTTLE_MS constant - All CSS variables use fallback pattern var(--new, var(--old)) - JSDoc on all public methods === BUILD === - metadata.mjs supports contributors array from package.json - @author now shows both victornpb and TheCellMaster - CLAUDE.md created with project documentation Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

hallo !
i'm working on adapting undiscord to a cli, and was adding unarchive capability. i thought i might as well pull request this to the main project :D i will note, it's not a perfect solution. it relies on the max retries to be greater than 1, and consumes a retry in the process of unarchiving, so it can be susceptible to network blips.
p.s. it looks like the retry logic has a small bug where it will print "Retrying..." even if max attempts has already been reached 👀 i didn't touch this as a part of my pr but wanted to call it out
testing
this change has been tested on my cli fork, which you can find the code for here: https://github.com/ayubun/undiscord-cli/blob/main/src/undiscord/undiscord-core.js#L412-L413
