Two knobs for the onboarding-burst quality work:
- TAPIR_ONBOARD_SUMMARIZER_MODEL (default iguana/gemma4-26b): the stronger model
the burst leads its chain with; empty collapses the burst onto the shared
processor (lookupOr, so explicit-empty disables).
- TAPIR_ONBOARD_MAX_VIDEO_SECONDS (default 14400/4h): upper duration bound for
burst picks; 0 disables, negative clamps to 0.
Table-driven tests cover defaults, explicit, disable, and invalid input.
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.

Bounds the connect-time onboarding summary burst (Feature 1). Hard-capped at 5
and clamped (negative->0, >cap->cap) so onboarding can never bulk-fetch; 0
disables. The cap bounds COUNT only — every fetch still flows through the shared
caption rate gate (ADR-014).

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.

Adds FetchBackoff (Go duration, default 1h) controlling how long the run loop
waits before re-fetching a transcript that returned HTTP 429. Zero means always
retry. Not required by ValidateForRun — a zero/unset value is a valid policy.

Parse TAPIR_* env into a typed Config with homelab defaults (gateway URL,
summarizer model, token ref, redirect addr). Secrets (gateway key, OAuth
client secret) come from env only; the refresh token never lives here — it is
addressed by an opaque ref behind the SecretStore port. Per-command validation
(ValidateForAuth/ValidateForRun) so each command demands only what it needs.
