Both must be nonempty or the credential is unavailable. They are +# read into memory only; 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. Persistence checks both the live inbox and its handled/ +# archive before creating a file, so a refetched update is never counted or +# delivered twice. A durable pending-delivery record bridges inbox persistence +# and offset advancement, and recovery reports it before polling again after a +# failed offset write. +# +# LOSS LIMITATION, stated plainly. The poll prints its result and clears the +# pending record before it exits, while the parent runner can durably capture +# output only after that exit. A crash after the clear but before the runner's +# capture can therefore strand an already-offset message without a wake. The +# unlink is not directory-fsynced, so power loss before the filesystem commits +# it can instead resurrect the marker and repeat a captured wake. No adapter- +# local transaction can close this source-side handoff window.

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. Telegram's `getUpdates` `timeout` parameter accepts up to +# roughly 50 seconds before the API itself becomes unreliable about honoring +# it.
