The scarce resource is the per-IP timedtext caption fetch (ADR-014); the pilot's
candidate set was mostly Shorts/clips/livestreams, each burning a fetch (a "none"
result is a completed fetch — it costs budget even when it yields nothing).
NewVideos now enriches candidates with one cheap Data API videos.list call
(contentDetails.duration + snippet.liveBroadcastContent — the quota API, a
DIFFERENT limit from the timedtext 429) and drops, before returning: videos
shorter than TAPIR_MIN_VIDEO_SECONDS (default 60) and any live/upcoming
broadcast. Dropped videos are never persisted, so the list declutters too.
Degrade-open: MinVideoSeconds=0 disables it (no quota call); a videos.list error
returns candidates unfiltered so discovery never breaks on a metadata hiccup. The
paste-a-URL path (VideoByID) is not filtered — an explicit request is honoured.

The lead-user rotation rotated the full ListAllUsers set, so a connectionless
orphan identity ate a rotation slot — collapsing onto the next real user and
skewing the lead share (two real users got 2/3 vs 1/3 instead of 50/50). Filter
to connected users BEFORE rotating so the rotation is over exactly the users that
consume the caption budget. A dead identity can no longer skew fairness.

buildUserRunner built the engine without engine.Transcripts = st, so the
scheduler — unlike the web "Summarize now" path — never read or wrote the shared
transcript cache. Every discovery pass re-fetched transcripts it had already
fetched, burning the scarce per-egress-IP caption budget (ADR-014) on redundant
work and starving other users' first-time fetches. The transcripts table was
empty despite summaries existing. Wire the cache on this path too.

The first friendly-pilot live run produced zero summaries: koala/phi4-mini hit
three silent failure modes — 8k context overflow on long transcripts (HTTP 400),
intermittent malformed JSON (highlights as a bare string), and no fallback wired
at all (summarizer.New(primary, nil)).
Keep phi4-mini as the fast primary and add resilience around it:
- Ordered endpoint chain (summarizer.NewChain): phi4-mini → koala/phi4-14b
(local) → berget/mistral-small (worst-case external). All reached through the
one LiteLLM gateway by alias.
- A parse failure now advances the chain like a transport error — the old
Primary→Fallback shape returned the parse error without trying anyone else.
- Tolerant parse: highlights/takeaways coerce string→[]string, absorbing the
common small-model quirk without spending a fallback round-trip.
- Transcript truncation (TAPIR_MAX_TRANSCRIPT_CHARS=18000) prevents the overflow
rather than recovering from it; validated to fit phi4-mini's 8k window.
- Bounded completion budget (TAPIR_SUMMARY_MAX_TOKENS=1500) — the old 8192 budget
itself contributed to the overflow.
Local-first guarantee preserved by ordering: external endpoint is tried only
after every local one fails. TAPIR_CLOUD_FALLBACK_MODEL="" disables it entirely
for client/NDA deployments.

The scheduler enumerates every user_identities row (ListAllUsers) and ran a
discovery pass for each — including users who never connected a video source.
Their per-user runner then tried to resolve a YouTube refresh token that was
never minted, logging a spurious "secrets: ref not found:
youtube/<uid>/refresh_token" every tick (e.g. stale Dex-era orphan identities
left by the Authentik migration).
Skip users whose ConnectionsForUser is empty before running their pass. Removes
the recurring noise — which actively misled a debug session into thinking a
healthy onboarded user was broken — with no change to connected users.

In automatic mode the scheduler now only summarizes videos published within
TAPIR_AUTO_SUMMARIZE_WINDOW (default ~7d). Older videos are still discovered
and listed — they keep the manual "Summarize" affordance — but are not
auto-processed, so a large back-catalogue (the maintainer's ~256-deep queue)
stops self-inflicting 429s against the per-IP caption gate each cycle (UX
review B1, recency design).
- runner.WithAutoWindow + Stats.SkippedTooOld; tooOld() treats a zero window
as disabled and an undated video as never-aged-out (processed, not stranded).
- An explicit manual request bypasses the bound even in auto mode (requested
videos are loaded in auto mode when a window is active).
- Wired through cmdRun, the scheduler's per-user runner, sumStats, and pass
logging. config: TAPIR_AUTO_SUMMARIZE_WINDOW (default 168h), .env.example.
- Account copy (A7) updated to match: "Automatic summarizes new videos from
about the last week; older videos stay browsable — summarize on demand."
The rate gate is untouched; the manual path still serialises through it. This
bounds auto LOAD, it does not fetch harder.

Stage 0's "returns and reads in >=2 weeks" gate can't be met while discovery
is host-side manual (`tapir run`): a newly onboarded user sees an empty list
and never comes back. Make Tapir watch on its own.
cmdServe launches a background goroutine (when TAPIR_DISCOVERY_INTERVAL > 0)
that runs a discovery pass for ALL users on that cadence: enumerate via the
un-RLS'd ListAllUsers, then run each user's pass through the EXISTING
runner.Runner — the only new code is the per-user loop, not a new scheduler.
Run-once-on-startup then ticked; ctx-cancelled on SIGTERM; per-user failures
(including buildUserRunner errors) are logged and skipped so one bad user
never aborts the rest. interval <= 0 disables it entirely (dev/tests).
buildUserRunner binds each runner to that user's own YouTube refresh token
(web.YouTubeTokenRef) — the Stage-1 per-tenant ref — reusing buildProcessor's
engine wiring. SetFetchRate is also wired in cmdServe so the click-path shares
the gate.
SINGLE-REPLICA is now load-bearing: the loop lives in the web process, so >1
replica double-runs discovery (429s + duplicate work). Documented in cmdServe
and warned at startup.
