feat(nodes): discord node support behaviours (part 2 of 3) - #2547
Merged
Merged
Conversation
Add a Discord bot source node (discord://, classType ["source"]) that connects a Discord bot to a pipeline over the Discord Gateway — the Discord counterpart to the telegram node. Routes incoming text and image/audio/ video/document attachments to the text/image/audio/video/tags lanes, and posts the pipeline's first answer back to the originating channel, message, or thread. Mirrors the Telegram endpoint architecture: scanObjects() -> WebServer (kept alive via self._server.run()) with the discord.py Gateway client launched as a background task from the async on_startup hook. Config: botToken (secure), guildIds, channelIds, ignoreBots, requireMention, replyMode (channel|reply|thread), showTyping, maxAttachmentBytes, sendResponses. Includes 2000-char reply chunking, rate-limit backoff, bot-loop prevention, and mention gating. Tests: 21 unit tests plus an env-gated live-gateway integration suite (skips unless DISCORD_BOT_TOKEN is set). Closes #1502 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Remove nodes/test/discord/test_integration.py: it imports the discord.py library at module top-level, which requires the (uninstalled-in-CI) dependency and a live DISCORD_BOT_TOKEN, and the package name collides with the node's own `discord` package during collection. It cannot run in CI. The pure-logic unit tests in test_discord.py remain. - Open services.json with encoding='utf-8' in the schema tests so they pass under CI's ASCII locale. - Replace the non-ASCII em dash in services.json with a hyphen. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Extract pure helpers (chunk_message, guess_media_type) into text_utils.py with no discord.py dependency, so unit tests exercise the real production code instead of reimplementing it, and can run in CI without discord.py. - chunk_message now hard-splits any single token/sentence longer than the 2000-char limit, so every emitted chunk is guaranteed to fit (previously an unbroken long token could produce an oversized chunk Discord would reject). - Stop processing further attachments once a non-empty answer is found. - Handle discord.RateLimited (which carries retry_after) instead of reading a nonexistent retry_after off discord.HTTPException. - Declare _guild_ids/_channel_ids as annotations only to avoid mutable list defaults shared at class scope; they are set per-instance in _run(). - requirements.txt: keep only discord.py (requests/fastapi/aiohttp are not imported directly and flagged unpinned/vulnerable by OSV). - README: use the UI-facing lane name "Data" for the document lane. - Rewrite test_discord.py to test the real helpers and services.json schema; drop tautological config/filtering tests. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Process attachments independently of the text pipeline so captioned uploads are ingested; the first non-empty answer (text first, then attachments in order, stopping at the first that answers) becomes the reply. - _send_response now abandons the remaining chunks on an unrecoverable send failure instead of silently continuing and dropping part of the reply. - Extract the message gating (self/bot/guild/channel/mention) into a pure should_process_message() predicate in text_utils.py and unit-test it; _on_message just wires primitives and schedules the task. - README: correct the attachment note to describe in-order processing that stops at the first attachment answer. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
guess_media_type() prefers Discord's reported content_type (parameters stripped) and only falls back to the file extension; the README had the order reversed. Fix the description to match, keeping the octet-stream default. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…docs - Remove the early `break` in the attachment loop so a source node ingests every attachment in a multi-attachment message (up to 10); still reply with only the first non-empty answer. The break silently dropped later attachments (no download, routing, or monitorCompleted). - Revert README lane name `Data` -> `tags` to match services.json and the telegram/webhook/core convention (no `Data` lane exists). - Clarify that discord.py handles 429s internally; the RateLimited branch is defensive (only fires with max_ratelimit_timeout, which is unset). - Regenerate stale GENERATED:PARAMS em-dash back to the services.json hyphen. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…iscord-source-node
…rom deep review Critical: - _run no longer constructs its own WebServer bound to --data_port. node.py already binds a shared WebServer on that port for every subprocess, so the second bind hit EADDRINUSE (and wired the target onto the wrong server) — the node could not start under EaaS. Now mirrors the Telegram node: register on the shared server and drive _startup/_shutdown on the shared server_loop, blocking scanObjects() on a shutdown event. Correctness: - _run_with_optional_typing now runs the pipeline exactly once; a typing- indicator enter/exit failure no longer re-executes it (double ingestion). - require_mention no longer satisfied by @everyone/@here (use direct message.mentions, not mentioned_in). - guildIds/channelIds coerced via _as_str_list so a scalar string no longer becomes a per-character allowlist; non-dict 'discord' config block no longer crashes _run. - guess_media_type lowercases the reported content type (mixed-case IMAGE/PNG routed correctly) and falls back to the extension when it normalizes empty. Docs: - Attachments download via discord.py's Attachment.read(), not aiohttp directly (aiohttp is transitive); drop the misleading "concurrently" wording. Tests: - New test_process_message.py (import-guarded, py3.10+/discord.py): attachment ingest-all + first-answer, exactly-once typing, allowlist coercion, and the @everyone gating fix. New MIME normalization cases in test_discord.py. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- Add a `discord` row to the Sources table in docs/README-nodes.md. - Add a Discord node line under [Unreleased] / Added in CHANGELOG.md. Addresses review feedback that both shared surfaces were missing. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…iscord-source-node # Conflicts: # CHANGELOG.md # docs/README-nodes.md
…d develop conformance Addresses kgarg2468's review: Lifecycle: terminal Gateway failures now fail the source promptly instead of idling forever with a dead bot. A missing token raises from _startup; login failure, missing Message Content Intent, an unexpected disconnect, or a generic gateway error record a fatal error and unblock _run, which re-raises so the engine marks the source failed. Successful startup still blocks until controlled shutdown; an intentional close during _shutdown is not treated as a failure. Security: all outbound sends (reply, thread, channel) pass discord.AllowedMentions.none() so model-generated text can never ping users, roles, @here or @everyone. Tests: the behavioral suite now stubs discord in sys.modules and loads the node as a synthetic package, so it runs deterministically in clean CI without discord.py installed and without a version skip (node annotations switched to Optional[...] so it imports on 3.10-). Added lifecycle tests (missing token, login failure, privileged-intent failure, unexpected close, cancellation, shutdown-marks-closing), allowed-mentions tests for all three reply modes plus thread reuse, and an oversized-attachment regression. Retained the multi-attachment ingest-all regression. Develop conformance: - services.json: add "documentation" URL. - README.md: restructure to the current node README schema (top-level Lanes table, drop the hand-written field table, fold sections under Notes); passes scripts/validate-node-readme.py. - credentials.json: register the discord credential (nodes:credentials-generate) so nodes:credentials-check passes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Addresses CodeRabbit re-review: - _send_chunk thread mode no longer calls message.create_thread() unconditionally: it posts into message.channel when the message is already inside a thread, creates a thread only for TextChannel messages, and falls back to a plain reply (mentions suppressed) in DMs and other non-threadable channels — previously these raised and dropped the response. - README: document that thread reply mode also needs Create Public Threads and Send Messages in Threads, and that it falls back to a reply where a thread cannot be created. - Tests: add thread-in-TextChannel, reuse-existing-thread, post-into-own-thread, and DM-fallback cases (58 tests pass on 3.9 and 3.11). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…iscord-source-node
Brings the discord source node to parity with the discord.js support bot it replaces. Every new setting is opt-in; with defaults the node behaves as it did before. - Replies: thread name template, length cap and archive duration; optional (i/n) chunk labels; allowlisted user/role mentions (never @everyone/@here); a failed thread creation falls back to a reply instead of losing it. - Context: earlier thread messages as context (threadHistoryLimit). - Escalation: pause a thread after an escalating reply, rebuild the pause from thread history after a restart, resume on an @mention; a team-name alias is turned into the team role mention; per-thread serialization while the pause is on. - Aimed at someone else: optional ack emoji, and the thread pauses. - Feedback: optional reactions on the last chunk of an answer. - Reply hygiene: strip leaked agent scratchpad and final-answer envelopes, never post engine or model errors, retry empty or scratchpad answers. - Attachments: optional text-file decoding and one merged answer per message. - Gating: allowed bot ids, mention-only channels, system and empty messages dropped. - Events: reaction, no_reply and outbound events with the message metadata, broadcast as apaevt_sse; reactions are scoped by the same guild, channel and bot gates as messages. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
With captureEvents on, the node writes every event it broadcasts (message, plus outbound, no_reply and reaction when their emit options are on) into a database tool node wired to the source by a control edge, so a support dashboard has a complete log even when nobody is watching the live stream. - One row per event in a fixed INSERT ... ON CONFLICT DO NOTHING through the database node's execute tool, keyed (message_id, event_type, event_key), so a redelivered Gateway event is ignored. - Off the answering path: a bounded queue and one writer thread; a slow or dead database costs a logged, rate-limited warning, never a Discord reply. - captureNodeId picks the database component, captureTable the table (validated, created if missing), captureSource the label written to each row's source column. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Unit tests for every new behaviour and its default: thread replies and fallbacks, thread-history context, escalation pause and history rebuild, per-thread serialization, aimed-elsewhere acks, feedback reactions, reply hygiene and retries, error suppression, team mention alias, chunk labels, attachment merge, reaction scoping, event payloads, config coercion, and the capture writer (row shape, SQL, failures, queue, thread lifecycle). The services.json schema tests assert every field, its UI registration and its default. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Describes each parity feature and the capture log in the node README, and regenerates the PARAMS schema table with nodes:docs-generate. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A live suite for the discord node against a real Discord server and engine, skipped unless DISCORD_LIVE=1 (ids and the token are read from files outside the repo). The README records each live round: what was run, what passed and the bugs it found. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…iscord-source-node
Collection of the live suite opened its seed and config files with the locale's encoding, which fails under an ASCII locale before the DISCORD_LIVE gate can skip anything. Every read and write now names UTF-8. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

With sanitizeReplies on, a provider failure still reached Discord: the engine's LLM layer turns the exception into the answer text "**LLM error** - ValueError: An error occurred with the API.", and no error signature matched it (the API pattern needs a word before "API"). Two signatures now catch it: the "**LLM error**" prefix at the start of the answer, and the bare "An error occurred with the API." sentence when it is the whole answer. Prose that only mentions API errors is not matched. The existing path then emits no_reply model_error. Found by the live engine suite (F40); verified live after the fix. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Inside a code fence the chunker hard-split at a character count, so every boundary cut a code line in two and a copied block was broken (live F12 and F44: 2 of 2 and 10 of 10 boundaries). It now breaks at the last newline in the second half of the window. The synthetic close/reopen fence pair stands in for that newline, so the reply rebuilds exactly by replacing each boundary pair with "\n". A newline right before a fence is passed over, so a boundary never produces an empty code block, and a single line longer than a chunk is still hard-split. A numbered reply also stripped no trailing whitespace before its label, leaving blank lines between the closing fence and "*(n/n)*"; each piece is now stripped first. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
pipelineTimeoutSeconds (default 0, off) gives up on a pipeline run
that has not answered within the limit and emits no_reply with reason
timeout. Each run (the question, each attachment, each retry) gets the
full limit; the run itself cannot be cancelled, so it finishes in the
background, returns its pipe, and its late answer is dropped. Before
this a hung pipeline left the question with no outcome at all.
Configuration and start failures now say what to fix:
- a list setting that starts with "[" but is not valid JSON is reported
in the task's warnings with the setting's name, instead of silently
becoming a literal id that matches nothing; in guildIds or channelIds
it fails the start, since the bot would otherwise answer nothing
- a botToken that is still an unresolved ${NAME} fails the start naming
the variable, instead of "login failed (invalid token)"
- with includeMemberMetadata on, a refused privileged intent leads with
the Server Members Intent (Message Content is usually already on)
Found by the live engine suite (F36, F38, F39, F41); all verified live.

test_engine_full.py (F01..F46) walks every discord node feature, success and failure, through real pipelines on a running engine, driven by the second bot in the support channel only. Node behaviour runs on deterministic pipes: an echo pipe (discord -> response_text keyed answers) and a fake-model pipe pointed at fake_llm.py, a scripted OpenAI-compatible endpoint for scratchpad, final-envelope, error-text, empty, retry, HTTP 429 and slow answers. One case runs the production pipe without tool_slack and capture. The suite is opt-in (DISCORD_LIVE=1 and DISCORD_E2E_FULL=1) and skips offline. The driver bot gains attachments, embeds, replies, reactions, deletes, thread creation and a typing recorder; its posts suppress mentions by default. The live README records the 44-row result matrix, the findings fixed in this branch, and the residue a run leaves. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…r stops stop() waits a bounded time for the capture worker. When a write is stuck on the database the worker is still busy after the join, and the rows still queued are lost when the daemon thread dies with the process, with nothing logged and nothing counted. stop() now warns with the approximate number of unwritten rows in that case. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The tile only tests whether botToken is set, yet read "connected"
even when login failed, an intent was missing or the ${NAME} never
resolved. It now reads "Token: configured" or "Token: missing", and the
README says the task status line is what reports the connection.
Raised by CodeRabbit on #1503.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The error-suppression sentence chained several clauses and did not parse. It is now a list that matches _ERROR_SIGNATURES in text_utils, with the posting, retry and sanitizeReplies-off behaviour unchanged. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
make_endpoint kept a hand-written copy of IEndpoint._run's config block that had drifted: escalation markers and feedback emojis were split on whitespace, several newer settings (mergeAttachments, numberChunks, teamMentionAlias, nonAnswerRetries, pipelineTimeoutSeconds, capture) were never applied, and numbers skipped the production coercion. It now runs the real _run(), stopped where it would reach the engine's shared web server, as the unit tests already do. The live README also marks B1 and G6 as fixed, pointing to N7 and F03. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
… API The aimed-at-others check called Message.fetch_reference, which discord.py does not have. The AttributeError was swallowed, so the node never learned who a reply was for, and with ignoreAimedAtOthers on every reply without a mention was treated as aimed at someone else, including a reply to the bot's own answer: it got the ack emoji and no answer. The target now comes from reference.resolved (sent with the reply by the Gateway), then reference.cached_message, then channel.fetch_message(reference.message_id). The unit tests delete fetch_reference from the fake message, so a call to a method discord.py does not have fails the test instead of passing; the old test mocked it. Reported in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
… is off The transcript left out every other bot that was not in allowedBotIds, even with ignoreBots off, where the node answers every bot: those bots' earlier messages were missing from the context of the next answer. A bot is now left out only when ignoreBots is on and it is not allowlisted, the same rule that decides whether the node answers it. The README sentence says so. Raised in review on #2547. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…h raw newlines _closing was checked only when a message got its slot, so during the shutdown grace the non-answer retry loop could still start up to nonAnswerRetries new pipeline runs, whose worker threads then kept running against a pipe being torn down. The loop now stops as soon as shutdown has begun. A final JSON envelope whose content held a literal newline failed strict json.loads, so the fallback posted the raw text with its escapes undecoded. The content is now decoded with strict=False. Raised in review on #2547. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ixes Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The agent nodes wrap a provider failure in their own text (Deep agent and LangChain agent "<stage> failed: <Name>:", the RocketRide agent's "Unable to produce final answer:", botocore's "An error occurred (<Code>) when calling the <Op> operation:"), so with default settings the raw provider error, which can carry account details, was posted. These shapes are now engine-owned error signatures. The API-error sentence now counts only as the whole reply and accepts a multi-word provider, the dashed LLM error form needs the engine's bold "**LLM error** — <Name>:" shape, and a traceback needs a File frame under its header, so prose that opens with any of them is posted. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…s scratchpad A single line starting with Action:, Observation: or Reasoning: was enough to call a reply scratchpad, so a real answer with a step list or a finding was suppressed with sanitizeReplies on and could not hand off with it off. A reply is now scratchpad only when it opens with Thought: or Action Input:, or holds a tool call (Action: with Action Input: on the next non-blank line) outside code. The ReAct agents stop generating at Observation:, so an opening Observation: is never theirs. This applies in handoff_part, sanitize_reply and the envelope unwrapping. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
… inline code A message that opened a code block without closing it put every later speaker line of the transcript inside code; only a clipped message was closed before. Every message with an odd fence count is closed now. Alias and marker matching skipped fenced blocks but not inline backtick spans, so an answer showing `@RocketRide team` or ``ESCALATED`` as an example pinged the team or paused the thread. Inline spans count as code everywhere "outside code" applies. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…as is set The per-user role-ping cooldown and the rule that only the final part of an answer may ping applied to every allowedMentionRoleIds entry, so a node without the support feature lost pings it used to send. Both now apply only when teamMentionAlias is set; without it every listed role is allowed on every answer, as before. README, setting descriptions and CHANGELOG say so. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
When a long answer ended with the hand-off and its last chunk failed to send, the thread was still paused although nobody saw the hand-off and no role was pinged. After a partial delivery the pause now looks only at the chunks that were posted, which matches how the pause is rebuilt from the thread's messages after a restart and how the ping cooldown is released. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
With teamMentionAlias set, the roles mentioned in the final part of an answer were allowed on every chunk of it, so the same role mentioned in leaked reasoning in an earlier chunk pinged too, and a mention inside code counted as a hand-off. Each chunk now gets its own allowed mentions: a role only where that chunk carries its mention from the final part, outside code. The cooldown and the ping decision use the same code-skipping rule. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…e bot's transcript lines Shutdown is checked once per message, when it gets a slot; a message already past that point could still start a pipeline run while the pipe was being torn down. _run_pipeline, which every run goes through, now refuses to start one once shutdown began, and the message ends with a no_reply event, reason shutdown. The bot's own lines in the thread transcript are labelled with its display name plus " (this bot)", which no Discord username can carry, so a user named like the bot cannot speak as it. Stale comments about the team-ping cooldown and the transcript role rewrite now match the code. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Thanks @mithileshgau for another careful round. All ten points from my last review are fixed, each with a test, and CodeRabbit's last point (thread history for a file-only follow-up) is fixed too.
Approve
Three non-blocking comments are inline, and each one carries a suggestion or a described fix. The most useful one: since the newest commit, the message SSE event of a file-only follow-up in a thread carries the thread transcript, and the README says it never does.
…her bots, release unused pings Three points from the review that approved #2547: - A file-only follow-up in a thread broadcast the whole framed prompt, transcript included, as the message event's text. The event now shows the user's words, or for a file-only message only the files, on the first run and on retries; the README says how a file-only message is framed in a thread. - Bot and webhook names are free text and could copy the "(this bot)" label. Other bots are shown with "(bot)" in the transcript. - A posted chunk whose role mention was not allowed to ping (one in the reasoning) kept the team-ping cooldown after the pinging chunk failed. _send_response now reports the roles each posted chunk could ping, and the reservation is kept only when one did. Raised in review on #2547. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Thanks @mithileshgau for fixing all three points from my last review in 45fdbec, each with a test. The message SSE event no longer carries the thread transcript. Other bots and webhooks are labelled (bot), so none of them can speak as this bot. A role mention in the reasoning no longer keeps the team-ping cooldown. The new tests pass in CI on Linux, macOS and Windows.
Approve
Two optional nits are inline: contextChars also counts the folded files while the docs call it the transcript size, and the rule for which roles a send may ping now lives in two places. CodeRabbit's last comment (backfill limited to guildIds) is fixed too.

…2548) * feat(nodes): add Discord bot source node (discord) Add a Discord bot source node (discord://, classType ["source"]) that connects a Discord bot to a pipeline over the Discord Gateway — the Discord counterpart to the telegram node. Routes incoming text and image/audio/ video/document attachments to the text/image/audio/video/tags lanes, and posts the pipeline's first answer back to the originating channel, message, or thread. Mirrors the Telegram endpoint architecture: scanObjects() -> WebServer (kept alive via self._server.run()) with the discord.py Gateway client launched as a background task from the async on_startup hook. Config: botToken (secure), guildIds, channelIds, ignoreBots, requireMention, replyMode (channel|reply|thread), showTyping, maxAttachmentBytes, sendResponses. Includes 2000-char reply chunking, rate-limit backoff, bot-loop prevention, and mention gating. Tests: 21 unit tests plus an env-gated live-gateway integration suite (skips unless DISCORD_BOT_TOKEN is set). Closes #1502 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(nodes): drop Discord live-gateway integration test, fix CI encoding - Remove nodes/test/discord/test_integration.py: it imports the discord.py library at module top-level, which requires the (uninstalled-in-CI) dependency and a live DISCORD_BOT_TOKEN, and the package name collides with the node's own `discord` package during collection. It cannot run in CI. The pure-logic unit tests in test_discord.py remain. - Open services.json with encoding='utf-8' in the schema tests so they pass under CI's ASCII locale. - Replace the non-ASCII em dash in services.json with a hyphen. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(nodes): address Discord node review feedback - Extract pure helpers (chunk_message, guess_media_type) into text_utils.py with no discord.py dependency, so unit tests exercise the real production code instead of reimplementing it, and can run in CI without discord.py. - chunk_message now hard-splits any single token/sentence longer than the 2000-char limit, so every emitted chunk is guaranteed to fit (previously an unbroken long token could produce an oversized chunk Discord would reject). - Stop processing further attachments once a non-empty answer is found. - Handle discord.RateLimited (which carries retry_after) instead of reading a nonexistent retry_after off discord.HTTPException. - Declare _guild_ids/_channel_ids as annotations only to avoid mutable list defaults shared at class scope; they are set per-instance in _run(). - requirements.txt: keep only discord.py (requests/fastapi/aiohttp are not imported directly and flagged unpinned/vulnerable by OSV). - README: use the UI-facing lane name "Data" for the document lane. - Rewrite test_discord.py to test the real helpers and services.json schema; drop tautological config/filtering tests. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * refactor(nodes): address second Discord review round - Process attachments independently of the text pipeline so captioned uploads are ingested; the first non-empty answer (text first, then attachments in order, stopping at the first that answers) becomes the reply. - _send_response now abandons the remaining chunks on an unrecoverable send failure instead of silently continuing and dropping part of the reply. - Extract the message gating (self/bot/guild/channel/mention) into a pure should_process_message() predicate in text_utils.py and unit-test it; _on_message just wires primitives and schedules the task. - README: correct the attachment note to describe in-order processing that stops at the first attachment answer. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(nodes): correct Discord MIME-detection precedence in README guess_media_type() prefers Discord's reported content_type (parameters stripped) and only falls back to the file extension; the README had the order reversed. Fix the description to match, keeping the octet-stream default. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(nodes): address Discord review — ingest all attachments, correct docs - Remove the early `break` in the attachment loop so a source node ingests every attachment in a multi-attachment message (up to 10); still reply with only the first non-empty answer. The break silently dropped later attachments (no download, routing, or monitorCompleted). - Revert README lane name `Data` -> `tags` to match services.json and the telegram/webhook/core convention (no `Data` lane exists). - Clarify that discord.py handles 429s internally; the RateLimited branch is defensive (only fires with max_ratelimit_timeout, which is unset). - Regenerate stale GENERATED:PARAMS em-dash back to the services.json hyphen. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(nodes): Discord node — use shared WebServer + correctness fixes from deep review Critical: - _run no longer constructs its own WebServer bound to --data_port. node.py already binds a shared WebServer on that port for every subprocess, so the second bind hit EADDRINUSE (and wired the target onto the wrong server) — the node could not start under EaaS. Now mirrors the Telegram node: register on the shared server and drive _startup/_shutdown on the shared server_loop, blocking scanObjects() on a shutdown event. Correctness: - _run_with_optional_typing now runs the pipeline exactly once; a typing- indicator enter/exit failure no longer re-executes it (double ingestion). - require_mention no longer satisfied by @everyone/@here (use direct message.mentions, not mentioned_in). - guildIds/channelIds coerced via _as_str_list so a scalar string no longer becomes a per-character allowlist; non-dict 'discord' config block no longer crashes _run. - guess_media_type lowercases the reported content type (mixed-case IMAGE/PNG routed correctly) and falls back to the extension when it normalizes empty. Docs: - Attachments download via discord.py's Attachment.read(), not aiohttp directly (aiohttp is transitive); drop the misleading "concurrently" wording. Tests: - New test_process_message.py (import-guarded, py3.10+/discord.py): attachment ingest-all + first-answer, exactly-once typing, allowlist coercion, and the @everyone gating fix. New MIME normalization cases in test_discord.py. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * docs(nodes): list Discord node in nodes catalog and CHANGELOG - Add a `discord` row to the Sources table in docs/README-nodes.md. - Add a Discord node line under [Unreleased] / Added in CHANGELOG.md. Addresses review feedback that both shared surfaces were missing. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(nodes): Discord lifecycle failure propagation, mention safety, and develop conformance Addresses kgarg2468's review: Lifecycle: terminal Gateway failures now fail the source promptly instead of idling forever with a dead bot. A missing token raises from _startup; login failure, missing Message Content Intent, an unexpected disconnect, or a generic gateway error record a fatal error and unblock _run, which re-raises so the engine marks the source failed. Successful startup still blocks until controlled shutdown; an intentional close during _shutdown is not treated as a failure. Security: all outbound sends (reply, thread, channel) pass discord.AllowedMentions.none() so model-generated text can never ping users, roles, @here or @everyone. Tests: the behavioral suite now stubs discord in sys.modules and loads the node as a synthetic package, so it runs deterministically in clean CI without discord.py installed and without a version skip (node annotations switched to Optional[...] so it imports on 3.10-). Added lifecycle tests (missing token, login failure, privileged-intent failure, unexpected close, cancellation, shutdown-marks-closing), allowed-mentions tests for all three reply modes plus thread reuse, and an oversized-attachment regression. Retained the multi-attachment ingest-all regression. Develop conformance: - services.json: add "documentation" URL. - README.md: restructure to the current node README schema (top-level Lanes table, drop the hand-written field table, fold sections under Notes); passes scripts/validate-node-readme.py. - credentials.json: register the discord credential (nodes:credentials-generate) so nodes:credentials-check passes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(nodes): Discord thread reply mode handles DMs and existing threads Addresses CodeRabbit re-review: - _send_chunk thread mode no longer calls message.create_thread() unconditionally: it posts into message.channel when the message is already inside a thread, creates a thread only for TextChannel messages, and falls back to a plain reply (mentions suppressed) in DMs and other non-threadable channels — previously these raised and dropped the response. - README: document that thread reply mode also needs Create Public Threads and Send Messages in Threads, and that it falls back to a reply where a thread cannot be created. - Tests: add thread-in-TextChannel, reuse-existing-thread, post-into-own-thread, and DM-fallback cases (58 tests pass on 3.9 and 3.11). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * feat(nodes): discord node support-bot parity features Brings the discord source node to parity with the discord.js support bot it replaces. Every new setting is opt-in; with defaults the node behaves as it did before. - Replies: thread name template, length cap and archive duration; optional (i/n) chunk labels; allowlisted user/role mentions (never @everyone/@here); a failed thread creation falls back to a reply instead of losing it. - Context: earlier thread messages as context (threadHistoryLimit). - Escalation: pause a thread after an escalating reply, rebuild the pause from thread history after a restart, resume on an @mention; a team-name alias is turned into the team role mention; per-thread serialization while the pause is on. - Aimed at someone else: optional ack emoji, and the thread pauses. - Feedback: optional reactions on the last chunk of an answer. - Reply hygiene: strip leaked agent scratchpad and final-answer envelopes, never post engine or model errors, retry empty or scratchpad answers. - Attachments: optional text-file decoding and one merged answer per message. - Gating: allowed bot ids, mention-only channels, system and empty messages dropped. - Events: reaction, no_reply and outbound events with the message metadata, broadcast as apaevt_sse; reactions are scoped by the same guild, channel and bot gates as messages. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(nodes): durable event capture for the discord node With captureEvents on, the node writes every event it broadcasts (message, plus outbound, no_reply and reaction when their emit options are on) into a database tool node wired to the source by a control edge, so a support dashboard has a complete log even when nobody is watching the live stream. - One row per event in a fixed INSERT ... ON CONFLICT DO NOTHING through the database node's execute tool, keyed (message_id, event_type, event_key), so a redelivered Gateway event is ignored. - Off the answering path: a bounded queue and one writer thread; a slow or dead database costs a logged, rate-limited warning, never a Discord reply. - captureNodeId picks the database component, captureTable the table (validated, created if missing), captureSource the label written to each row's source column. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): cover the discord node parity features and capture Unit tests for every new behaviour and its default: thread replies and fallbacks, thread-history context, escalation pause and history rebuild, per-thread serialization, aimed-elsewhere acks, feedback reactions, reply hygiene and retries, error suppression, team mention alias, chunk labels, attachment merge, reaction scoping, event payloads, config coercion, and the capture writer (row shape, SQL, failures, queue, thread lifecycle). The services.json schema tests assert every field, its UI registration and its default. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): document the discord node's new settings Describes each parity feature and the capture log in the node README, and regenerates the PARAMS schema table with nodes:docs-generate. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): add the gated live Discord harness and test notes A live suite for the discord node against a real Discord server and engine, skipped unless DISCORD_LIVE=1 (ids and the token are read from files outside the repo). The README records each live round: what was run, what passed and the bugs it found. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): read discord live-harness files as UTF-8 Collection of the live suite opened its seed and config files with the locale's encoding, which fails under an ASCII locale before the DISCORD_LIVE gate can skip anything. Every read and write now names UTF-8. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs: note the discord node's support-bot features in the changelog Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): never post an engine LLM error as a discord reply With sanitizeReplies on, a provider failure still reached Discord: the engine's LLM layer turns the exception into the answer text "**LLM error** - ValueError: An error occurred with the API.", and no error signature matched it (the API pattern needs a word before "API"). Two signatures now catch it: the "**LLM error**" prefix at the start of the answer, and the bare "An error occurred with the API." sentence when it is the whole answer. Prose that only mentions API errors is not matched. The existing path then emits no_reply model_error. Found by the live engine suite (F40); verified live after the fix. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): split fenced discord replies between lines Inside a code fence the chunker hard-split at a character count, so every boundary cut a code line in two and a copied block was broken (live F12 and F44: 2 of 2 and 10 of 10 boundaries). It now breaks at the last newline in the second half of the window. The synthetic close/reopen fence pair stands in for that newline, so the reply rebuilds exactly by replacing each boundary pair with "\n". A newline right before a fence is passed over, so a boundary never produces an empty code block, and a single line longer than a chunk is still hard-split. A numbered reply also stripped no trailing whitespace before its label, leaving blank lines between the closing fence and "*(n/n)*"; each piece is now stripped first. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(nodes): add discord pipelineTimeoutSeconds and name config failures pipelineTimeoutSeconds (default 0, off) gives up on a pipeline run that has not answered within the limit and emits no_reply with reason timeout. Each run (the question, each attachment, each retry) gets the full limit; the run itself cannot be cancelled, so it finishes in the background, returns its pipe, and its late answer is dropped. Before this a hung pipeline left the question with no outcome at all. Configuration and start failures now say what to fix: - a list setting that starts with "[" but is not valid JSON is reported in the task's warnings with the setting's name, instead of silently becoming a literal id that matches nothing; in guildIds or channelIds it fails the start, since the bot would otherwise answer nothing - a botToken that is still an unresolved ${NAME} fails the start naming the variable, instead of "login failed (invalid token)" - with includeMemberMetadata on, a refused privileged intent leads with the Server Members Intent (Message Content is usually already on) Found by the live engine suite (F36, F38, F39, F41); all verified live. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): add the full live engine suite for the discord node test_engine_full.py (F01..F46) walks every discord node feature, success and failure, through real pipelines on a running engine, driven by the second bot in the support channel only. Node behaviour runs on deterministic pipes: an echo pipe (discord -> response_text keyed answers) and a fake-model pipe pointed at fake_llm.py, a scripted OpenAI-compatible endpoint for scratchpad, final-envelope, error-text, empty, retry, HTTP 429 and slow answers. One case runs the production pipe without tool_slack and capture. The suite is opt-in (DISCORD_LIVE=1 and DISCORD_E2E_FULL=1) and skips offline. The driver bot gains attachments, embeds, replies, reactions, deletes, thread creation and a typing recorder; its posts suppress mentions by default. The live README records the 44-row result matrix, the findings fixed in this branch, and the residue a run leaves. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): report capture rows left unwritten when the discord writer stops stop() waits a bounded time for the capture worker. When a write is stuck on the database the worker is still busy after the join, and the rows still queued are lost when the daemon thread dies with the process, with nothing logged and nothing counted. stop() now warns with the approximate number of unwritten rows in that case. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): label the discord tile by token presence, not connection The tile only tests whether botToken is set, yet read "connected" even when login failed, an intent was missing or the ${NAME} never resolved. It now reads "Token: configured" or "Token: missing", and the README says the task status line is what reports the connection. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): list the reply patterns the discord node treats as errors The error-suppression sentence chained several clauses and did not parse. It is now a list that matches _ERROR_SIGNATURES in text_utils, with the posting, retry and sanitizeReplies-off behaviour unchanged. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): parse live discord harness config through the real _run make_endpoint kept a hand-written copy of IEndpoint._run's config block that had drifted: escalation markers and feedback emojis were split on whitespace, several newer settings (mergeAttachments, numberChunks, teamMentionAlias, nonAnswerRetries, pipelineTimeoutSeconds, capture) were never applied, and numbers skipped the production coercion. It now runs the real _run(), stopped where it would reach the engine's shared web server, as the unit tests already do. The live README also marks B1 and G6 as fixed, pointing to N7 and F03. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): look up a discord reply's target with the real discord.py API The aimed-at-others check called Message.fetch_reference, which discord.py does not have. The AttributeError was swallowed, so the node never learned who a reply was for, and with ignoreAimedAtOthers on every reply without a mention was treated as aimed at someone else, including a reply to the bot's own answer: it got the ack emoji and no answer. The target now comes from reference.resolved (sent with the reply by the Gateway), then reference.cached_message, then channel.fetch_message(reference.message_id). The unit tests delete fetch_reference from the fake message, so a call to a method discord.py does not have fails the test instead of passing; the old test mocked it. Reported in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): add a live case for a reply to the discord bot without a mention F23b replies to the bot's own answer with the ping off, so only the reply-target lookup can tell the node the message is for it. The live README records the finding as N8; the case has not been run live yet. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(nodes): move discord support behaviours to a follow-up PR PR #1503 is being split into three stacked PRs. This removes the support behaviours from the base Discord node: thread history as context, the escalation pause and per-thread serialization, skipping messages aimed at others, feedback reactions, the team mention alias, reply sanitizing and error detection, non-answer retries, the pipeline timeout and backfill. Their services.json fields, config parsing, helpers, text utilities, README sections and unit tests go with them; the follow-up PR re-adds them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(nodes): move discord event capture to a follow-up PR The durable Postgres capture of the node's events moves to the third PR of the split. This deletes capture.py and its tests, the captureEvents, captureNodeId, captureTable and captureSource fields, and the capture writer lifecycle and call sites in IEndpoint. The engine-warning helper _config_warning relied on now lives in IEndpoint, so the node no longer imports the capture module. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): fail the discord start on an unset variable in guildIds or channelIds The engine passes an unknown ${NAME} through as literal text. In guildIds or channelIds it became an allowlist id that matches nothing, so the bot connected and answered nobody. The start now fails, on the same path as the broken-JSON check, naming the field and the variable. In allowedMentionRoleIds and allowedMentionUserIds such an entry was only dropped with a debug line; it now also produces a task warning naming the field and the variable. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): keep discord thread settings within what Discord accepts Discord rejects a thread name longer than 100 characters and any auto-archive duration other than 60, 1440, 4320 or 10080 minutes, either of which cost the whole answer with a 400. threadNameMaxLength now declares minimum 1 and maximum 100 and is clamped to that range in code. threadAutoArchiveMinutes is an enum of the accepted durations plus 0 for the channel default; the code still falls back to the channel default for any other value that reaches it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): say which discord text is broadcast and kept in the run log The README called the apaevt_sse broadcast live-only. It is not: the engine writes every SSE body into the task's run log, so it is visible to every client monitoring the task and kept afterwards. The README now says so and lists exactly which message text the node puts in those bodies (the question on message events, the answer on outbound events), so operators can cover it in their privacy notice. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * chore(nodes): add comment blocks to the discord services.json Every top-level key of the Discord services.json now has a // comment block explaining its purpose, in the same form as the Telegram node's. The file is JSONC from here on, so the unit tests and the live suite drop its whole-line comments before parsing it, and a schema test checks that each top-level key keeps its comment block. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): remove internal data from the discord live suite The repo is public and the live folder carried internal data. The replay seeds are now ten made-up questions about a generic pipeline tool, the README is cut down to the layers, how to run them, the variables they need, the residue policy and what they do not cover, and the test pipe's prompt no longer names an internal bot. The token and id files are read from DISCORD_LIVE_TOKEN_FILE and DISCORD_LIVE_IDS_FILE instead of fixed home-directory paths, and the layers skip with a reason when they are unset. Result files go to a temp directory or a *_RESULTS_DIR override instead of a repo-local folder. The live cases for behaviours that moved to the follow-up PRs (D11, D16..D19 and F14, F20..F26, F32..F35, F40, F41b, F45, F46) and the helpers only they used are removed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): regenerate the discord README settings table Generated by nodes:docs-generate after the support behaviours and capture moved to follow-up PRs and the thread settings gained their limits. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(nodes): add event capture to the discord node Re-add the opt-in durable capture of the node's events into a database node connected to the source by a tool control edge: capture.py, the captureEvents, captureNodeId, captureTable and captureSource fields, the capture writer lifecycle and its call sites next to every SSE broadcast, the README section, and the unit tests. IEndpoint shares capture._engine_warning again instead of keeping its own copy. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): keep every part of a discord message in the capture log A message row was keyed (message_id, 'message', '') for the text pass and for every attachment, so ON CONFLICT DO NOTHING kept only the first: the attachment rows were lost, or with mergeAttachments the question text was. The event_key of a message row now names the part: 'text' for the text pass, '<lane>:<groupIndex>' for each attachment, with ':retry:<n>' appended for a retried pass. Both come from the broadcast body, so a key rebuilt from the run log matches. Keys for the other event types are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): capture discord events only into PostgreSQL, inserting before any DDL The capture SQL is PostgreSQL's, but any database node was accepted, and the writer ran CREATE TABLE before its first INSERT, so a database user that may only insert into an existing table could not capture at all. While resolving the database node the writer now asks it for its dialect once; anything other than PostgreSQL turns capture off for the run with one warning naming the dialect. Each write is an INSERT first, and only an INSERT that fails because the table does not exist runs the CREATE TABLE and CREATE INDEX statements and retries the insert once. The README and the captureEvents description say PostgreSQL only and list the rights the database user needs. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): stop the discord capture worker when the node stops A capture write stuck on the database outlived stop(): the worker went on borrowing pipes and writing the rest of the queue after the node had stopped, and with a full queue the stop sentinel never got in, so the thread never ended. The writer now has a stop event. stop() still gives the worker its timeout to drain, then sets the event (at once when the queue is full). The worker checks it before every write, so once set it borrows no further pipe, drops what is still queued and ends; the unwritten-rows warning now carries the exact count. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): say which database node discord capture may use Capture writes through the database node's execute tool, so it needs allow_execute, which opens raw execute, begin, commit and rollback to every caller of that node. The README now says to use a separate database node only for capture, never one an agent or any other tool caller can reach, with a database user that has only the rights capture needs. The privacy paragraph now also says that with capture on the broadcast text is stored in the capture table. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): add discord capture to the live suite F32..F34 run event capture through a real engine into a disposable PostgreSQL database, gated on the DISCORD_E2E_PG_* variables: - F32: with no table yet, the first insert creates discord_events, and the question and answer land with the configured captureSource. - F33: text plus a .md attachment keeps two message rows (text, text:1), and inserting the same rows again adds nothing. - F34: with the database stopped mid-run the bot still answers, and capture resumes once it is back. The live README lists the cases and the new variables. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): regenerate the discord README settings table Generated by nodes:docs-generate after the capture settings came back and their descriptions gained "PostgreSQL only". Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): list decoded text attachments among the broadcast discord text With mergeAttachments off, a text-like attachment is sent through the text lane as "[attachment <name>]" plus its decoded contents, and that text is broadcast on its message event (clipped at 2000 characters), so it lands in the run log too. The privacy list now names it. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): key discord no_reply capture rows by a stable reason code The no_reply dedupe key was the raw reason, which can be exception text that differs between deliveries of the same message, so a redelivery inserted a second row. A known reason code is now its own key; any other reason shares the key "error" and keeps its text in the payload. The dropped-row counter is also updated under a lock, since events are submitted from several worker threads at once. Raised by CodeRabbit on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): handle blank discord text, partial delivery and late messages Three edge cases in the base node: - The intake gate strips a message's text to decide whether it has anything to ask, but processing read the raw text, so whitespace next to a file ran a text pass of its own (and skipped the file-only framing when merging). Processing now uses the same stripped answer. - When a later chunk failed after earlier ones were posted, the outbound event looked like a full delivery. _send_response now reports whether every chunk went out, and the outbound event carries it as "complete". - A message arriving after shutdown began could start a task the shutdown never awaited. _on_message now ignores messages once closing. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): say which discord events need emitOutbound or emitNoReply The README implied an outbound or send_failed no_reply event always follows an answer. Both need their opt-in flag, which is off by default. It also documents the new "complete" field on outbound events. Raised by CodeRabbit on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): require confirmation before the discord capture cases touch a database F32 drops the capture table and F34 stops the database container, and until now any DISCORD_E2E_PG_* values were enough to run them. They now also need DISCORD_E2E_PG_DISPOSABLE set to exactly "<container>/<database>", and they skip when that database holds any table other than the capture table. Raised by CodeRabbit on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): fail clearly when the discord capture database cannot be checked When the disposable-database check could not query the database (the container is down), its error text was read as "other tables exist" and the case skipped. It now fails with the query error. F34 also runs the check before it starts a capture pipeline, so nothing captures into a database that turns out not to be disposable. Raised by CodeRabbit on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs: keep the discord changelog line to what the base node ships The entry still listed thread history, escalation pause, ack and feedback reactions, reply hygiene and retries, and event capture, which moved to follow-up PRs. List only what this node ships. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): catch every unset variable in the discord settings The engine resolves only ROCKETRIDE_* variables and replaces any other ${NAME} with the literal <REDACTED>, which the node did not recognise: a token failed as "invalid token" and list entries matched nothing. Both forms are now named, and the message says only ROCKETRIDE_* server variables are resolved. requireMentionChannelIds now fails the start like guildIds and channelIds (an unset entry made the mention gate fail open), allowedBotIds warns like the mention lists, and JSON list items get the same strip and comma/whitespace split as a bare string. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): say how to keep strangers from adding the discord bot With guildIds and channelIds empty (the default) the bot answers in every server it is added to and in DMs, and a new Discord application is a Public Bot. The setup steps now say to turn off Public Bot, the README recommends setting guildIds in production and says DMs are answered only while both lists are empty, and the node warns once at start when guildIds is empty. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(nodes): bound how many discord messages are processed at once Every message that passed the gates started its own task, and each one holds its downloaded attachments (up to maxAttachmentBytes, up to 10 files) in memory until the pipeline answers, so nothing limited memory. A new maxConcurrentMessages setting (default 4, 1 to 32) sizes a semaphore created in _startup; further messages wait their turn rather than being dropped. maxAttachmentBytes gets a 100 MB maximum, enforced in code as well. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): never let a blank discord answer win over a real one Answers were chosen by truthiness, so a whitespace-only answer such as a newline beat a real attachment answer, and with merging on a blank text pass hid the first attachment answer. Every pipeline answer is now normalised the way the question text is before it is chosen, a blank attachment answer is no longer folded into the merged question, and _send_response treats an answer with no non-blank chunks as nothing to send. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): decode discord text attachments the same way on both paths With mergeAttachments off a text file was sliced to textAttachmentMaxChars (0 sent an empty body, a negative value dropped the end) and never checked for binary content; with it on, 0 or less kept everything and a NUL byte meant binary. Both paths now share one decode helper and one cap rule: 0 means no limit, and a file with a NUL byte (such as UTF-16) is not text. textAttachmentMaxChars gets a minimum of 0 in the schema. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * chore(nodes): drop the unexplained discord.py version floor Every discord.py API the node uses exists in 2.0 and later, and node dependencies are resolved together into one constraints lock, so an arbitrary floor could move other packages for no reason. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): document what the discord send helpers return _send_response said it returned None but returns messageIds, destination and complete; the docstring now describes each key. _emit_outbound_event and _record_sent had no docstring. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): route discord files of unlisted types by their extension The extension table knows 15 extensions; any other file without a content type became application/octet-stream and went to the tags lane, so .m4a or .flac audio reached the document lane. After the content type and the table, the extension is now looked up with Python's mimetypes before falling back to application/octet-stream. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): regenerate the discord README settings table Generated by nodes:docs-generate for maxConcurrentMessages, the new bounds on maxAttachmentBytes and textAttachmentMaxChars, and the dependency line without a version floor. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): skip queued discord messages once shutdown has begun A message waiting for a maxConcurrentMessages slot is already tracked as in flight, so shutdown waits for it; once it got its slot nothing checked that shutdown had begun, and it downloaded, ran the pipeline and replied anyway. It now returns as soon as it gets the slot (with a no_reply "shutdown" event when emitNoReply is on). The README notes that the slot limit is shared across servers and what it does not buy. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): warn about an open discord bot only when no allowlist limits it With channelIds set, only those channels and their threads are answered and DMs are refused, so the start-up warning that the bot answers in any server it is added to was wrong. It now fires only when guildIds and channelIds are both empty, and the README says the same. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): fail the discord start when an allowlist resolves to nothing The engine replaces a set ${ROCKETRIDE_X} with its value, so an empty value reaches the node as "". Blank items are dropped, the list became empty, and an empty guildIds, channelIds or requireMentionChannelIds means "everywhere". A list that was given items but resolves to no ids now fails the start with the field's name; a genuinely empty list (missing, None, [], '', '[]') still means all. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(nodes): let discord list settings keep phrases whole _as_str_list always split JSON items and bare strings on commas and whitespace, which suits ids but breaks a list of phrases. It now takes split=True; with split=False items are kept whole (still stripped, blank ones still dropped). Every current caller keeps the default. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): read UTF-16 and BOM-prefixed discord text files as text Any NUL byte meant "binary", so UTF-16 files (Windows Notepad "Unicode", PowerShell 5.1 redirects) were never read as text: with merging off they went to the binary lanes, with merging on they were dropped with only a debug line. A UTF-8 BOM also survived into the text. The decode now checks for a UTF-16 BOM first, otherwise decodes as utf-8-sig, and only then treats a NUL as binary content. In merge mode a text-like file that is still binary becomes its own binary lane object (reusing the bytes already downloaded) instead of being dropped. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): guess discord file types from Python's built-in table only mimetypes.guess_type also reads the Windows registry and /etc/mime.types, so the extension fallback routed the same file differently per host: on Windows .csv became application/vnd.ms-excel and .ts a video type (it is video/mp2t on macOS too). The fallback now asks a module-level mimetypes.MimeTypes(), which CPython fills from its built-in defaults only; the node's own extension table still answers first. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): accept only numeric ids in the discord allowlists An entry in guildIds, channelIds or requireMentionChannelIds that is not plain ASCII digits (a pasted <#123>, a channel or server name) matched nothing, so the mention gate failed open or the bot answered nothing. The start now fails naming the field and the entry, and suggests the id inside a pasted mention. The mention allowlists and allowedBotIds use the same digit rule, so '123²' no longer reaches int() in every send. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): ignore discord reactions once shutdown has begun The Gateway keeps delivering reactions while _shutdown waits for in-flight messages, and each one still opened a pipe. _on_raw_reaction now returns when _closing is set, and checks again just before the emit. The reaction authorIsBot now uses the same _reactor_is_bot answer as the gate, so a removal by an allowlisted bot is reported as a bot. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): split prose in fenced discord replies at a word boundary A reply with a code fence anywhere goes through the fenced chunker, which only broke at a newline in the second half of the window and otherwise cut by character count, even in prose outside the code block. Outside an open fence it now falls back to the last sentence end, then the last whitespace, in the second half before cutting by count. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): bound and normalise the discord attachment settings maxAttachmentBytes of zero or below skipped every attachment with only a debug line; it is now clamped to at least 1 and the schema declares minimum 1. textAttachmentExtensions entries typed without a dot (md, json) never matched os.path.splitext; each entry is now normalised to a lowercase extension with one leading dot, and blank entries are dropped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): coerce discord booleans and overflowing numbers from the engine _as_int caught TypeError and ValueError but not OverflowError, so a number setting of inf or 1e400 failed _run with an unrelated traceback; it now falls back to the default. The ten boolean settings were used raw, so a string-like 'false' read as True; a new _as_bool reads real bools as-is and true/false, 1/0, yes/no, on/off strings in any case, else the default. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): document discord events, reasons and setup accurately The tags lane also carries the reaction, no_reply and outbound event objects, and events have their own entry URL and name; the README now says so. The no_reply reasons are listed (no_answer, send_failed, shutdown, or an error message clipped to 200 characters), and so is what happens when the question is deleted before the answer is posted. Configuration headings use the field titles, each paragraph sits under the field it is about, and the broadcast section moves under Notes. The Developer Portal steps use Reset Token, the reactions intent is described as one the node turns on itself, and the MIME fallback examples are .avi and .bmp, which the node's own table does not list. In services.json, guildIds and channelIds default to [] and the text-attachment and emitNoReply descriptions match the behaviour. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): complete the discord docstrings and drop references to a private bot Several Args sections left out parameters the functions take (_on_message wait, _process_attachment meta and attachment_index, _run_text_pipeline meta, object_name and attachment_id, _run_binary_pipeline message_id, attachment_index and meta, should_process_message parent_channel_id and allowed_bot_ids). Comments and docstrings no longer point at functions of a bot that is not in this repo; the sentences explaining the behaviour stay. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(nodes): make the discord live suite neutral and self-describing The live README now lists the variables L3 and L4 need on the engine and says ROCKETRIDE_DISCORD_E2E_NO_SUCH_TOKEN must stay unset, and asks for Python 3.10+. engine_min.pipe gets a fresh project_id (the SDK's use() contract carries it at the top level) and a short generic assistant prompt with no escalation line. E05 tested that escalation prompt, which belongs to a follow-up change, and E06 was a skipping placeholder; both are removed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): regenerate the discord README settings table Generated by nodes:docs-generate for the new bounds and list defaults and the updated textAttachmentExtensions and emitNoReply descriptions. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): wait for discord reaction emits at shutdown and hint ids by kind A reaction emit already under way was not tracked, so shutdown did not wait for it and tore the endpoint down beneath it. The emit is now a tracked task, like a message handler. The second closing check before the emit could never fire (nothing can change the flag between the two checks) and its test only passed by setting the flag from a mock; both are gone. A pasted mention in an id list suggested the digits inside it even when they were the id of something else (a role in a channel list, a channel in the server list). The hint now gives the digits only for the right kind of mention and otherwise says what was pasted. Also documents the arguments of _emit_event_pipeline and the return of _emit_no_reply_event. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): never cut a discord reply inside a code-fence opener or a word When a chunk window ended inside or just after a code-fence opener line, chunk 1 ended with a split language name or an empty code block. A block whose opener line and first code line do not both fit now starts the next chunk, and the newline search never cuts right after an opener line. A reply with no fence also hard-split a line longer than the limit in the middle of a word. It is now cut at the last sentence end or whitespace in the second half of the window, by character count only when there is none. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(nodes): read discord booleans with the shared parse_bool The node had its own _as_bool, which duplicated parse_bool in ai.common.utils. Every boolean setting now goes through the shared helper. The engine passes JSON booleans as real bool values, so the tests that fed string-like proxies to a boolean are replaced with tests for real bools and plain strings. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): keep secrets out of discord id errors and bound id length A bot token or secret ${ROCKETRIDE_*} value pasted into an id list was echoed in full by the start error, the task warnings and the debug log. Every message about a list entry now goes through one helper that shows a mention whole and anything else longer than 12 characters as its first 12 characters followed by an ellipsis. An id is also bounded to a 64-bit snowflake (at most 20 digits, below 2**64), so two ids pasted together are rejected as non-numeric on the same fatal or warning path as any other bad entry. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): treat a non-positive discord attachment cap as unset maxAttachmentBytes was floored at 1, but a 1-byte cap skips every real attachment just as 0 did. A value of 0 or below now means "not set" and falls back to the 25 MB default, matching config_int in ai.common.utils; the value is still clamped to at most 100 MB. The schema keeps its minimum of 1. Raised in review on #1503. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): regenerate the discord settings table Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(discord): let the capture edge be drawn in the pipeline editor The canvas draws a tool handle only for the keys of a service's invoke block, and the Discord source had none, so the database node capture writes to could only be wired by hand-editing the .pipe. Add the invoke capability and an optional invoke.tool slot (min 0, so a pipeline without capture needs nothing connected), shaped like the webhook tools source. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(discord): do not take a missing column for a missing capture table PostgreSQL's undefined-column error (42703) reads 'column "x" of relation "<table>" does not exist', which the unanchored pattern matched. A table of another shape then took the DDL path on every row: a CREATE that an INSERT-only user may not run, logged instead of the real error. Anchor the pattern to the start of the driver message; the 42P01 and UndefinedTable checks stay. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(discord): make INSERT the only grant capture needs on an existing table seq was BIGSERIAL, whose default calls nextval() and so needs USAGE on the table's sequence: an operator who pre-created the table and granted only INSERT got "permission denied for sequence" on every row. Declare seq as BIGINT GENERATED BY DEFAULT AS IDENTITY, which needs no sequence grant (PostgreSQL 10 or later; capture already writes to PostgreSQL only). The README and the captureEvents description now state the exact grants. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(discord): warn about allow_execute in the capture field descriptions Capture writes through the database node's execute tool, so it needs Allow direct query execution, which opens raw SQL to every caller of that node. The README said so, but the editor description, the only text a pipeline builder sees, did not, so the likely fix for "execute tool is disabled" was to enable it on the node an agent already uses. Say it in the captureEvents and captureNodeId descriptions. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(discord): drain the capture queue on a normal stop _run blocked on an event only a fatal Gateway error set, so on Stop the process was killed inside the wait and the daemon writer died with whatever was queued, often the last reply's outbound row. Stop sends SIGTERM, which sets the engine's cancellation flag, and the supervisor force-kills only five seconds later. Poll isCancelled() between bounded waits, as the webhook source does, so the Gateway close and the two-second capture drain run on a normal stop too. The README states what is still lost when teardown outlasts the kill. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(discord): strip NUL characters from captured rows PostgreSQL text rejects NUL and jsonb rejects the \u0000 json.dumps writes for it, so one NUL failed the row for good. A UTF-16 .txt decoded as text with errors='ignore' keeps its NUL bytes, so the question row was lost while the bot still answered. capture_row now scrubs NUL from every string in the metadata and payload (copies, so the SSE broadcast is untouched) before building text and payload. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(discord): say that captured rows are kept until the operator deletes them Capture never prunes, and a message deleted in Discord keeps its row, with the full text in payload. Operators need that for their privacy notice and for deletion requests, so the README now says retention and deletion are theirs, with an example scheduled DELETE. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(discord): tighten the capture table name and quote it in all SQL - The table-name and source-label patterns used match with ^...$, and $ also matches before a trailing newline, so 'discord_events\n' passed. Both now use fullmatch. - A reserved word such as 'user' passed the check and then failed every INSERT. The name is now lower-cased and double-quoted in all SQL, so Discord_Events still means discord_events. - Index and constraint names share the table namespace, so the index 'events_thread' for table 'events' collided with a table of that name. The derived names now use a '$' suffix, which no accepted table name can contain, and the docstring says so. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(discord): guard the F33 live capture case like the others F33 writes into the capture table directly, but unlike F32 and F34 it did not first check that the database holds nothing but that table. Call _require_disposable_database() before _start, as F32 does. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(discord): capture one message's text and attachment as two rows Drive a whole message (text plus a PDF) through _process_message with mergeAttachments off and on, and deliver it twice. Each part gets its own message row (text, binary:1) under the same message id, the second delivery sends the same keys again, and the table keeps two rows. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs: add the discord event capture changelog line #2547 has its own line for the support behaviours; #2548 had none. Add one line for what this PR adds: optional capture of the node's events to a database through a database node. Raised in review on #2548. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): regenerate the discord settings table after the review fixes Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): document the discord capture connection The node now declares an invoke slot for the capture database, so the README schema requires a Connections section with one row per invoke key. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): drop the invoke capability from the discord source The "invoke" capability marks a node that other nodes invoke: the canvas draws a top target handle for it that nothing can be connected to. The capture edge to a database node comes from the invoke.tool block alone, and no engine code reads the capability on the calling side (it is only parsed into a flag; control edges are wired from the .pipe control array without checking it). Keep the block, drop the capability. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): check the discord capture table exists before the first insert On a new table the first capture write was an INSERT that failed, and the database node logs every failed raw statement at error level together with its bound parameters, so the user's question landed in the error log. Before the first INSERT of a run, ask once with SELECT to_regclass($1) (the quoted, lower-cased name; no privilege needed) and run the DDL only when it answers NULL. A check that raises is a failed write and is asked again on the next row; an answer that cannot be read keeps the existing INSERT-first path, and the missing-table fallback after a failed INSERT stays for a table dropped mid-run. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): key discord capture rows on the base node's no_reply reasons only The capture key builder, its tests and the README listed no_reply reasons (non_answer, model_error, paused, aimed_elsewhere, timeout) and a :retry:<n> message key that only the follow-up node changes in #2547 produce. Keep this PR consistent with the node it ships against: the fixed reasons are no_answer, send_failed and shutdown, anything else is keyed error, and a message key is text or <lane>:<groupIndex>. The removed parts come back together with #2547. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): store the whole discord message text in capture rows A message row's text was the SSE payload, which the node clips at 2000 characters, while the docs said the payload is stored unclipped. Discord allows messages of up to 4000 characters, so a long question lost its second half in the durable record. The broadcast keeps its clip; the capture row now gets the user's whole message. In merge mode it gets only the user's own text: the folded file contents and other lanes' answers are pipeline input, not what the user wrote. README and comments now say which text is clipped where. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): count discord capture rows that race the writer's stop A handler that took the capture writer just before Stop could still call submit(): either it saw the writer stopped and returned without a word, or it queued its row behind the stop marker, where the worker never reads it. Both lost a row silently. submit() now checks and queues under the same lock stop() holds while it closes the writer, so no row can land behind the marker, and a row submitted after stop() is counted in unwritten and reported in a throttled warning. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(nodes): share one _shown_entry and _engine_warning in discord text_utils capture.py carried its own copy of _shown_entry (without the endpoint's rule that a mention is shown whole) and owned _engine_warning, which the endpoint imported from it. Both now live once in text_utils.py, which has no engine or discord.py imports, and capture.py and IEndpoint.py import them from there; the endpoint's behaviour is kept. The bare capture loader in test_capture.py now loads the module inside a synthetic package so its relative import resolves, as the other loaders already do. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): correct the discord capture comments, docs and live F34 check - Comments no longer say a no_reply reason becomes the dedupe key: an exception-text reason is keyed error, and the 200-character clip keeps the event bounded. - captureEvents description: failures are logged in full once, then at most once per 30 seconds; the "follow-up" event type is gone (it is not in this PR). - CHANGELOG: outbound, no_reply and reaction rows need their emit settings on. - README: the exact DDL capture runs, for operators who create the table in advance, with the UNIQUE (message_id, event_type, event_key) constraint marked required (ON CONFLICT is refused without it); a test keeps the block equal to CREATE_TABLE_SQL. The stop paragraph states the real budget: stopping the writer takes up to about 4 s (2 s to queue the stop marker, 2 s to join) of the engine's 5 s. - Live F34 now passes only when the failed and recovered log lines are found, as the live README describes, and is skipped without DISCORD_E2E_ENGINE_LOG. F32's wording follows the table check that now runs before the first insert. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * docs(nodes): regenerate the discord settings table after the review fixes Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): key discord capture rows on the support behaviours' reasons and retries Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(nodes): one rule for discord send pings and accurate contextChars docs Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): keep folded files out of a retried discord capture row A non-answer retry re-ran the text pass without its capture text, so a retried merge pass of a message that is only attachments stored the folded file contents in its message row. The text pass now carries a captureText (the user's own words) that every retry passes on. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): let an INSERT-only role write discord capture rows PostgreSQL requires SELECT on the columns of a named ON CONFLICT target, even for DO NOTHING, so a database user granted only INSERT got "permission denied" for every capture row (measured on PostgreSQL 16). The insert now uses a target-less ON CONFLICT DO NOTHING: the table's UNIQUE constraint still turns a redelivered event into a conflict. The README, services.json and docstrings now say INSERT alone is enough, and that a hand-made table without the UNIQUE constraint stops deduplicating rather than failing every row. The live suite gains F32b, an INSERT-only role writing into an existing table, and F33 repeats its insert the way the node now writes it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): keep each discord source's capture rows apart Two Discord sources writing to one capture table and seeing the same message produced the same (message_id, event_type, event_key), so the second source's row was dropped as a redelivery. The UNIQUE dedupe key is now (source, message_id, event_type, event_key); a redelivery to the same source is still ignored. The README DDL block (which a test keeps equal to CREATE_TABLE_SQL) and the row-key description follow. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): stop discord capture after a failure that cannot fix itself The database node logs every failed statement at error level together with its bound values, so a capture table that could never be written (a refused grant, a missing column) put every user's message into the server log, once per row, for the whole run. The writer now tells the two kinds of failure apart. A failure no retry can fix (permission denied, no matching unique constraint, a missing column, a missing table whose CREATE fails, the execute tool switched off, a connected node that is not a database) turns capture off for the run with one warning naming the cause, never the row's text. Any other failure, usually the database being down, starts a 60-second backoff in which rows are dropped and counted without borrowing a pipe; the next row after it is tried again, and the recovery line reports how many were dropped. The README privacy paragraph now says a failed capture write is logged by the database node with the row's values, and that capture stops after a lasting failure. The live F34 case waits out the backoff before it checks that capture resumed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): check discord captureNodeId against the connected tool nodes A configured captureNodeId was used without looking at the source's tool edge, so a typo, or an id wired to something else, failed every capture row for the whole run. The id is now checked once against getControllerNodeIds('tool'); one that is not there turns capture off with one warning, its value shown clipped like any configured entry. A node that lets the dialect call through without an answer (one that does not own the tool) is treated as not a database: capture goes off with one warning, as for a "not owned" error. A driver message that quotes the configured node id shows <captureNodeId> instead, since the field may hold a pasted secret. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): store no exception text in a discord no_reply capture row A no_reply whose reason is an exception message (a pipeline, download or unexpected failure) carried that message into the capture row's payload. Exception text can hold account details, key fragments or internal URLs, and the capture table is kept far longer than the run log. The row now stores reason "error" in its payload, matching its event_key; the SSE broadcast is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): bound the strings a queued discord capture row holds The capture payload kept the text the node handed over unclipped, and a text attachment read with textAttachmentMaxChars 0 has no limit of its own, so each of the up to 1000 queued rows could hold megabytes. Every string in the stored payload is now clipped at PAYLOAD_TEXT_MAX_CHARS (65536, ending in an ellipsis), which is far above any Discord message or reply. The text column keeps its own 8000-character clip. The README and the module docstring's "Bounded" property now say so. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(nodes): date a discord message capture row by when it was sent occurred_at was the moment the node handled the event, so a message replayed by backfill at startup was dated to the restart rather than to when it was written. A message row now takes Discord's createdAt from its metadata, and falls back to the node's time when that is absent, unreadable, or has no time zone. Outbound, no_reply and reaction rows carry the question's metadata, so they keep the node's time. The README now defines occurred_at and captured_at. Co-Authored-By: Claude Opus 5.5 <…

Summary
Part 2 of 3 of the Discord source node, split out of #1503 at review. This PR adds the support behaviours on top of the base node, which is now in
develop(#1503 merged). Every behaviour is behind its own setting and off by default, with one exception: engine and provider error text (**LLM error**,LLM error:, tracebacks,Error code: NNN - {...}) is never posted, whatever the settings, because it can carry account details.The branch now targets
develop. It contains #1503's final version through merges (no rebase), so this diff is only the support behaviours.What it adds
threadmode the original question from the parent channel is included.sanitizeReplies): leaked agent scratchpad and{"type":"final"}envelopes are stripped, empty or scratchpad answers are asked again (nonAnswerRetries), and answers that open like an error (Error:,ValueError:) are not posted. Each suppressed answer is reported asno_replymodel_errorand a task warning (never the answer text).pipelineTimeoutSeconds, off by default): a run that has not answered is given up withno_replytimeout; runs use their own bounded thread pool.backfillLimit, at most 100): the most recent N messages per channel are processed at startup. Messages the bot already answered, threaded, replied to or reacted to are skipped in every reply mode; backfill does not run whilesendResponsesis off.Settings added
threadHistoryLimit(0, max 100),threadHistoryMaxChars(6000, max 20000),escalationPause(false),escalationMarkers([]),teamMentionAlias(""),ignoreAimedAtOthers(false),ackEmoji(""),feedbackReactions(false),feedbackEmojis(check mark, cross mark),sanitizeReplies(false),nonAnswerRetries(1, max 3),pipelineTimeoutSeconds(0, off),backfillLimit(0, max 100).escalationMarkersandfeedbackEmojiskeep each phrase whole (split=False).Review fixes in this PR
From the latest review of this PR:
raw_mentions), live and when the pause is rebuilt; the aimed-elsewhere gate still usesmentionssanitizeReplieson or off; a scratchpad without a final answer never pings or pausesthreadmode left the original question out of the transcriptresolved,cached_message, then a fetch)_run failed, any-word labels and a leading code fenceFinal Answer:or an envelope and on retries; the bareLLM error:form is covered0turns each one offsendResponsesoffsanitizeReplies/nonAnswerRetriesdescriptions incompleteAlso fixed before asking for review: the generic error openings no longer hide real answers by default (only with
sanitizeReplies), the transcript cap starts on a whole speaker line,ackEmojiis trimmed, the README timeout wording matches the code, docstrings are complete, and comments no longer refer to a bot outside this repo. The shared helper forFinal Answer:stripping (also copied in the CrewAI and DeepAgent nodes) is left for a follow-up.From the review that approved this PR (all non-blocking):
Error code: NNN -counts only with a JSON, list or HTML body; agent-wrapped provider errors (Deep agent, LangChain, RocketRide agent, Bedrock) are now caught; the API sentence,LLM errorand traceback shapes are anchored so prose about them is postedThought:label could hand offAction:thenAction Input:) anywhere outside code marks a scratchpad; a singleAction:line in a real answer does notteamMentionAliasset the per-user cooldown covers every allowed role; without it,allowedMentionRoleIdsbehaves as on develop\rand Unicode line separators could start a speaker line(this bot); open fences are closed in every messageignoreBotsoffignoreBotsis on and not allowlistedno_replyshutdown)Also fixed before asking again: a thread pauses only when the hand-off was actually posted. Left for follow-ups: suppressing bare agent failure messages such as
