A new Reddit account cannot start chats until Reddit considers it
established, and nothing in the app previously did anything about that.
Account growth posts a small number of AI-written comments per day on
active threads in an operator-chosen list of communities, per account,
so the history that lifts the hold actually accumulates.
Growth is account-scoped rather than part of the shared outreach funnel:
karma, comment history and pacing all belong to one identity. It runs as
the lowest-priority work in the account runtime, after inbound replies,
and deliberately keeps running while an account is held out of outbound
messaging.
Comments publish without operator review, so the guards are the feature:
- Both screening stages fail closed. A deterministic gate rejects links,
contact solicitation, user tags, filler and any text that reveals the
generator; the classifier must actively approve with confidence, and
an outage stalls growth rather than publishing unreviewed text.
- Thread text reaches the model only as fenced untrusted data, since
Reddit posts do contain instructions aimed at automated readers.
- The daily allowance is adaptive, not configured: it starts at two per
day and rises only while comments survive and earn upvotes.
- Posted comments are swept at ~15m/2h/24h with one batched info.json
request, plus a single signed-out probe that detects a comment the
public cannot see. Two consecutive removals, an invisible comment, or
a captcha challenge pauses the account until an operator clears it. A
failed probe never pauses anything.
- One comment per thread across every owned account, enforced by a
unique index, because two of our accounts on one post is the easiest
pattern to correlate.
- A comment interrupted mid-post is abandoned, never retried: we cannot
know whether the write landed and a duplicate cannot be withdrawn.
- Reddit's refusals are authoritative — a ban disables that community
for that account, a throttle backs off at the scope Reddit named, and
a signed-out response invalidates the session.
Comments are submitted through the account's own browser session against
the old.reddit form endpoint, which returns machine-readable error codes
and needs no credentials beyond the cookies already imported.
API-first: /api/growth exposes state, settings, the community list and
pause/resume, all verified against a local instance. Route responses are
parsed with the shared contracts in tests so the server-side mirror
cannot drift from what the dashboard expects.

Missing conversations: recipient Reddit accounts that are deleted or suspended
left conversations unaccounted for. A new RecipientAccountStatusService polls
Reddit for the users behind cached conversations and records their account
status durably, with progressive backfill and delta-media fixes in ChatService
so history and images are no longer dropped mid-sync.
Media: attachMedia now surfaces download failures as MediaAttachmentError so the
sync cursor can be retried instead of silently losing an image, recognizes image
bytes when Matrix returns a generic content type, and keeps separate gallery
occurrences when the same asset appears in more than one event.
Manual inbox tab: the conversations list now carries the reply-loop status, so
the inbox can separate conversations the operator is driving by hand from the
ones automation is still handling. A Manual filter pill and a per-row chip
explain why each conversation was handed over.
