From 4d131a5f57616735fc50b2acde2eb8b71f76d64a Mon Sep 17 00:00:00 2001 From: bingb0t5 Date: Mon, 24 Aug 2026 12:55:15 +0700 Subject: [PATCH 01/30] feat(bin): add a Telegram process-event adapter Registers the captain's Telegram channel with the generic process-to-event runner so a captain message wakes firstmate within seconds instead of waiting up to five minutes for a check sweep. The adapter is deliberately thin: it owns Telegram's getUpdates long poll, the write-before-offset invariant that keeps a captain message from being lost, and token handling; ownership, durable capture, publication, and restart recovery stay with bin/fm-procevent.sh. The channel is never terminal on its own - only an explicit retire stops it. --- .agents/skills/process-event-sources/SKILL.md | 4 + bin/fm-procevent-telegram.sh | 331 ++++++++++++++++++ docs/configuration.md | 3 + tests/fm-procevent-telegram.test.sh | 252 +++++++++++++ 4 files changed, 590 insertions(+) create mode 100755 bin/fm-procevent-telegram.sh create mode 100755 tests/fm-procevent-telegram.test.sh diff --git a/.agents/skills/process-event-sources/SKILL.md b/.agents/skills/process-event-sources/SKILL.md index 9d400cc119c..ed71a944e88 100644 --- a/.agents/skills/process-event-sources/SKILL.md +++ b/.agents/skills/process-event-sources/SKILL.md @@ -41,6 +41,9 @@ The runner then passes each captured result to that source's own adapter `answer This is generic: any adapter with an `answers` command works, and the runner still wakes you to act on the result. `captain-hold-lifecycle` owns when a binding is required and what the keys must be. +The captain's Telegram channel is armed and retired through `bin/fm-procevent-telegram.sh arm` / `retire`; its header owns the exact commands, credential path, and timeout. +Unlike every other adapter here, it is never terminal on its own - the captain's channel must never retire itself - so only an explicit `retire` stops it. + A configured remote secondmate reply source is armed and handled through `bin/fm-procevent-remote-reply.sh`.

The bot token lives at ~/.config/beanz/telegram.env (mode 600, +# gitignored, outside this repo; override the path with FM_TELEGRAM_ENV_FILE +# for tests). It is read into memory for the one curl call that needs it and +# is never echoed, logged, or written anywhere else: the token reaches curl +# through an inline `-K -` config fed over a pipe (never as a literal argv +# element, so it does not appear in a process listing either), and every +# result this adapter produces is a fixed marker line plus a message count - +# never the token, never the credential file's own bytes. +# +# THE BLOCKING CHILD is this script's own `poll` subcommand (internal; not +# listed above because arm is the only supported way to register it). Each +# invocation runs exactly one Telegram `getUpdates` long poll and then exits, +# so the runner captures a result and restarts it - the same run-to-completion +# shape as every other adapter here, not a persistent daemon. +# +# WRITE-BEFORE-OFFSET is the one invariant this adapter cannot compromise on. +# Telegram permanently deletes updates once `getUpdates` is called with a +# higher offset, and there is no way to rewind and replay them - this was +# proven by accident while wiring up the original check-sweep version of this +# channel. So every text message is durably written under +# state/telegram-inbox/ BEFORE the offset file advances past it, and if any +# write in a batch fails, the offset is not advanced at all: the whole batch, +# including messages already written earlier in that same batch, is fetched +# again next time. A duplicate inbox file (same update id, same content) is +# harmless and idempotent; a lost message from the captain is not recoverable +# at all. A non-text update (a photo, a sticker, a chat-membership change) is +# consumed the same way - its id is folded into the advanced offset - but +# produces no inbox file and never counts toward "message" below. +# +# EXIT-CODE CONTRACT for `poll`, precise because the generic runner's own +# capture rule is precise: exit 0 always captures and publishes a wake +# regardless of what (if anything) was printed, and only a NONZERO exit with +# EMPTY stdout leaves the source armed with no capture and no wake at all +# (bin/fm-procevent.sh's own `no-result` path). So: +# - at least one new text message was durably written: exit 0, stdout is +# exactly `message: `. This is the only path that wakes firstmate. +# - no updates at all, or only non-text updates, or a transient network or +# API error: exit 1, no stdout. Silent, no capture, no wake - the runner +# restarts this poll on its next reconcile pass, which is what keeps +# latency down to that pass's cadence instead of the check sweep. +# - the credential file is absent or unreadable: exit 0, no stdout. This is +# a deliberate, narrow exception to "nonzero for nothing to report": an +# unconfigured home never reaches this path at all because `arm` above +# already refused to register it, so in ordinary operation this exit code +# is never observed by the runner. It only fires if a credential file +# present at arm time is later removed or blanked while the source stays +# armed - an operator-caused edge case, not the steady state. In that +# narrow window this DOES produce one empty capture and one check wake per +# restart until credentials are restored or the source is retired; that +# gap is accepted rather than hidden, because closing it would mean either +# re-validating credentials on every poll cycle through a side channel +# `poll` cannot see (arm's own refusal already covers the common case) or +# silently returning a nonzero exit here instead of the zero this command +# documents - and this script would rather be honest about a narrow, +# operator-triggered gap than quietly disagree with its own contract. +# +# POLL TIMEOUT.

Replace that with an atomic claim: this adapter always writes its own complete, fsynced payload to a private temp file first, then hardlinks that finished file onto the shared .json name. A successful hardlink is an exclusive, race-free claim. A failed one (name already taken) is resolved by parsing whatever is already there - a complete, well-formed payload for that update means another claimant (the legacy script or an earlier invocation of this adapter) already delivered it, so this poll no-ops without a second captain-visible wake; anything else means a claimant, most likely the legacy script, is still mid-write, and that update blocks the whole batch's offset advance exactly like a failed write, so an unadvanced retry gives the write time to finish. handled/ is checked first so an archived update is never recreated in the live inbox. This does not make true simultaneous overlap (both producers inside getUpdates for the same not-yet-advanced offset) free - the legacy script has no knowledge of this adapter and can still fire its own independent wake through the check sweep, which nothing here can suppress. Only ensuring no legacy invocation is genuinely in flight before arming (not merely deregistering it) closes that window; the header documents this plainly rather than claiming a guarantee the design cannot make. Also keeps the two accumulated fixes this branch already carries: a durable pending-delivery record so an offset-write failure never strands an already- written message, checked and reported before any credential validation. Adds a regression test that reproduces the legacy script's exact non-atomic write shape mid-write, overlapping a batch that also contains a genuinely new update, and proves the batch blocks without corruption or duplication and resolves correctly once the legacy write finishes. --- bin/fm-procevent-telegram.sh | 298 +++++++++++++++++++++------- tests/fm-procevent-telegram.test.sh | 96 ++++++++- 2 files changed, 315 insertions(+), 79 deletions(-) diff --git a/bin/fm-procevent-telegram.sh b/bin/fm-procevent-telegram.sh index f25eb0ecf3d..2d776182a7c 100755 --- a/bin/fm-procevent-telegram.sh +++ b/bin/fm-procevent-telegram.sh @@ -11,7 +11,10 @@ # arm Register this home's single Telegram source with the runner. # Refuses when no readable credential file exists (see below), so # an unconfigured home never gets a registered source and never -# sees a Telegram-shaped wake at all. +# sees a Telegram-shaped wake at all.

So every text message is durably written under +# state/telegram-inbox/ BEFORE the offset file advances past it, and if any +# write in a batch fails, the offset is not advanced at all: the whole batch, +# including messages already written earlier in that same batch, is fetched +# again next time. A duplicate inbox file (same update id, same content) is +# harmless and idempotent; a lost message from the captain is not recoverable +# at all. A non-text update (a photo, a sticker, a chat-membership change) is +# consumed the same way - its id is folded into the advanced offset - but +# produces no inbox file and never counts toward "message" below. +# +# EXIT-CODE CONTRACT for `poll`, precise because the generic runner's own +# capture rule is precise: exit 0 always captures and publishes a wake +# regardless of what (if anything) was printed, and only a NONZERO exit with +# EMPTY stdout leaves the source armed with no capture and no wake at all +# (bin/fm-procevent.sh's own `no-result` path). So: +# - at least one new text message was durably written: exit 0, stdout is +# exactly `message: `. This is the only path that wakes firstmate. +# - no updates at all, or only non-text updates, or a transient network or +# API error: exit 1, no stdout. Silent, no capture, no wake - the runner +# restarts this poll on its next reconcile pass, which is what keeps +# latency down to that pass's cadence instead of the check sweep. +# - the credential file is absent or unreadable: exit 0, no stdout. This is +# a deliberate, narrow exception to "nonzero for nothing to report": an +# unconfigured home never reaches this path at all because `arm` above +# already refused to register it, so in ordinary operation this exit code +# is never observed by the runner. It only fires if a credential file +# present at arm time is later removed or blanked while the source stays +# armed - an operator-caused edge case, not the steady state. In that +# narrow window this DOES produce one empty capture and one check wake per +# restart until credentials are restored or the source is retired; that +# gap is accepted rather than hidden, because closing it would mean either +# re-validating credentials on every poll cycle through a side channel +# `poll` cannot see (arm's own refusal already covers the common case) or +# silently returning a nonzero exit here instead of the zero this command +# documents - and this script would rather be honest about a narrow, +# operator-triggered gap than quietly disagree with its own contract. +# +# POLL TIMEOUT.

Every failure path - a mutated spec or action executable, a condition error past its budget, an expired deadline, a failed action, or an earlier fire whose outcome was never captured - produces a terminal captured outcome that wakes firstmate rather than a silent retry, and a durable single-fire marker claimed before the action makes restarts and re-polls unable to fire it twice. diff --git a/tests/fm-procevent-telegram.test.sh b/tests/fm-procevent-telegram.test.sh new file mode 100755 index 00000000000..255e7338c44 --- /dev/null +++ b/tests/fm-procevent-telegram.test.sh @@ -0,0 +1,252 @@ +#!/usr/bin/env bash +# Behavior tests for the Telegram process-to-event adapter +# (bin/fm-procevent-telegram.sh). +# +# `curl` is replaced by a fake binary on PATH for every scenario here: no test +# talks to the real Telegram API.

Replace that with an atomic claim: this adapter always writes its own complete, fsynced payload to a private temp file first, then hardlinks that finished file onto the shared .json name. A successful hardlink is an exclusive, race-free claim. A failed one (name already taken) is resolved by parsing whatever is already there - a complete, well-formed payload for that update means another claimant (the legacy script or an earlier invocation of this adapter) already delivered it, so this poll no-ops without a second captain-visible wake; anything else means a claimant, most likely the legacy script, is still mid-write, and that update blocks the whole batch's offset advance exactly like a failed write, so an unadvanced retry gives the write time to finish. handled/ is checked first so an archived update is never recreated in the live inbox. This does not make true simultaneous overlap (both producers inside getUpdates for the same not-yet-advanced offset) free - the legacy script has no knowledge of this adapter and can still fire its own independent wake through the check sweep, which nothing here can suppress. Only ensuring no legacy invocation is genuinely in flight before arming (not merely deregistering it) closes that window; the header documents this plainly rather than claiming a guarantee the design cannot make. Also keeps the two accumulated fixes this branch already carries: a durable pending-delivery record so an offset-write failure never strands an already- written message, checked and reported before any credential validation. Adds a regression test that reproduces the legacy script's exact non-atomic write shape mid-write, overlapping a batch that also contains a genuinely new update, and proves the batch blocks without corruption or duplication and resolves correctly once the legacy write finishes. --- bin/fm-procevent-telegram.sh | 298 +++++++++++++++++++++------- tests/fm-procevent-telegram.test.sh | 96 ++++++++- 2 files changed, 315 insertions(+), 79 deletions(-) diff --git a/bin/fm-procevent-telegram.sh b/bin/fm-procevent-telegram.sh index f25eb0ecf3d..2d776182a7c 100755 --- a/bin/fm-procevent-telegram.sh +++ b/bin/fm-procevent-telegram.sh @@ -11,7 +11,10 @@ # arm Register this home's single Telegram source with the runner. # Refuses when no readable credential file exists (see below), so # an unconfigured home never gets a registered source and never -# sees a Telegram-shaped wake at all. +# sees a Telegram-shaped wake at all.
