NewVideos called search.list at 100 quota units/call. With ~143 channels one
discovery pass = 14,300 units > the 10,000/day YouTube Data API cap, exhausting
the whole day in a single loop (live quotaExceeded).
Switch to playlistItems.list (1 unit/call) against the channel's uploads
playlist. For a standard channel id UCxxxx the uploads playlist is UUxxxx,
derived at zero API cost (uploadsPlaylistID). Non-standard ids fall back to
channels.list (1 unit) to read contentDetails.relatedPlaylists.uploads. Newest-
first ordering and MaxVideosPerSubscription cap preserved.
Side effect: removing search.list also removes the accountDelegationForbidden
error that endpoint threw for one channel — no separate hardening needed.
New per-pass quota: /subscriptions (1) + ~1/channel discovery (143) + any
channels.list fallbacks ≈ 145 units/day, well under 10k. Caption fetch (ADR-010
timedtext) uses no Data API quota.

The Data API captions.download endpoint is owner-only: every subscription
video the user does not own returned HTTP 403, producing 0 summaries and a
~150-line error spew in the first live Stage-0 run. Captions-first (ADR-007)
is sound; only the acquisition mechanism was wrong.
FetchTranscript now resolves caption tracks from the InnerTube player
response (ANDROID client, unauthenticated) and GETs the chosen track's
timedtext baseUrl with a plain http.Client — no OAuth token, which can break
the endpoint. The srv3 XML, json3, and legacy <transcript> formats all parse;
non-asr tracks in a preferred language win. Watch-page ytInitialPlayerResponse
scrape is the fallback when InnerTube returns no tracks.
Degrade, don't error (explicit quick-fix): no captionTracks, empty baseUrl, a
non-200 fetch, or an unparseable body yield Source=none, not an error. Only
genuine transport faults error — this kills the spew. OAuth stays on
ListSubscriptions/NewVideos (Data API); only transcript fetch goes unauthed.
Validated live from koala: the ANDROID client returned working baseUrls and
real transcript text for public videos the run identity does not own.

The Sink port carries only a Summary, so video title/url/published_at would
never reach the store. UpsertVideo (new file, store.go untouched) persists them
and returns the durable videos.id UUID, idempotent on
(user_id, provider, provider_video_id). The run loop uses that id as v.ID, so
it equals summaries.video_id and SeenVideoIDs dedup survives restarts.
subscription_id stays NULL: the YouTube resource id is not a UUID (Stage 0).

ListSummaries (recent-first, user-scoped, limit) and GetSummaryByVideo
LEFT JOIN videos for title/url/published_at, null-safe when no videos
row exists. Channel mirrors provider for now — channel_title lives on
the not-yet-migrated subscriptions table (data-model.md). New file so it
does not collide with Worker F's concurrent edits to store.go.

Implements ports.SecretStore over a 0600 JSON file as a stand-in for op/ESO so
the demo runs without live op. Put persists atomically (temp + rename) and
merges; Get returns ErrNotFound for unknown refs so a missing token fails loud.
Behind the port, so swapping to op/ESO later is wiring, not code (ADR-002).

The copied OpenAI-compatible client sent no max_tokens. Thinking models
(qwen3, deepseek-r1) spend their budget on the reasoning trace and return
EMPTY content when max_tokens is unset, which the summarizer treats as an
error. ADR-004 says change Tapir's copy rather than the hyperguild upstream,
so set a generous default (8192) leaving room for both reasoning and output.

Implements ports.Sink over Postgres (pgx/v5 + pgxpool, DSN from env per
estate convention). This is the primary sink (ADR-003) and the source of
the engine's durable, cross-restart dedup — the in-engine processed map is
process-lifetime only.
- Migrations (golang-migrate, NNN_name.up/down.sql per estate convention,
applied from an embedded FS on New): users, videos, transcripts,
summaries, sink_deliveries. Every user-owned table carries user_id
(Stage-0 per-user isolation promise, data-model.md). summaries has
UNIQUE(user_id, video_id) — at most one summary per video; highlights /
takeaways are jsonb.
- Deliver upserts the summary idempotently on (user_id, video_id)
(ON CONFLICT DO UPDATE) inside one tx with its sink_delivery row. Re-
delivering the same summary updates in place, never duplicates or errors.
- Dedup reads (store methods, not a new port): HasSummary(ctx,userID,
videoID) and SeenVideoIDs(ctx,userID) — both user_id-scoped, so one
user never sees another's videos.
summaries.video_id is intentionally not FK-constrained to videos at Stage 0:
the sink receives only a Summary, so the dedup key stands alone; video-row
persistence is the engine/source's concern, deferred.
Tested against a real in-process Postgres via embedded-postgres (real SQL:
constraints, ON CONFLICT, jsonb, user_id scoping) — no docker, no live
cluster, no creds, fully offline.
Deps: golang-migrate/migrate/v4 and jackc/pgx/v5 (runtime),
fergusstrange/embedded-postgres + stretchr/testify (test-only). go mod tidy
raised the go directive to 1.25.0 (minimum required by the dep graph;
estate elsewhere already runs 1.26.1).

Implements ports.VideoSource against the YouTube Data API v3:
ListSubscriptions (paginated), NewVideos (recent per channel), and
captions-first FetchTranscript — an absent caption track yields
domain.SourceNone (not an error) per ADR-007, with no audio download
or speech-to-text.
OAuth is written fresh on golang.org/x/oauth2 (ADR-006, distinct from
ingestion's inbound MCP auth); the Google token endpoint is inlined to
avoid the heavy x/oauth2/google dep. The per-connection refresh token is
resolved through the SecretStore port from an opaque TokenSecretRef and
is never stored on the adapter or logged.
Unit-tested against an httptest server + fake SecretStore (no live
googleapis egress): subscriptions list/pagination, new-video detection,
captions present -> Source set, captions absent -> SourceNone no error,
and secret-ref resolution failure surfacing as an error.
oauth2 pinned to v0.30.0 to keep the go directive at 1.23.x (koala
runner), not the v0.36 line that requires a newer toolchain.

Implement ports.Summarizer in internal/adapters/summarizer. It routes through a
local Primary endpoint first and an optional BYO Fallback, owning the routing
itself (not delegating to llm.Router) so it can record AIProvider, AIModel, and
FallbackUsed on domain.Summary. Prompt asks for JSON {summary, highlights,
takeaways}; the parser tolerates thinking-model fences/reasoning and rejects an
empty summary.
The summarizer is the single egress point for content toward an AI model, so it
enforces the local-first guarantee from ai_routing.feature: with no BYO
configured (nil fallback) there is no external endpoint, so content reaches the
local stack and nowhere else. Tests assert all four scenarios via a fake client.
Model alias is config (TAPIR_SUMMARIZER_MODEL, host/name) — not hardcoded;
docs/homelab-integration.md notes it stays `confirm` and that thinking models
need an explicit max_tokens or they return empty content.

Copy hyperguild/ingestion/internal/llm into internal/adapters/llm and own it.
Tapir owes that repo nothing at the dependency level — no module dep added.
Router gives the local-Primary -> BYO-Fallback path needed for ai_routing.feature.
Copied tests rewritten from testify to stdlib testing to keep go.mod
dependency-free (repo has zero deps; acceptance tests are stdlib too).
