chore(spike): recover the /bygge toolchain from tmpfs (#28)

analyze_srt.py, build_page.py and transcode.yaml produced the /bygge
prototype. They were sitting in a session scratchpad on tmpfs, one reboot
from gone, while spike issues #29-#31 were written as if they had to be
built from scratch.

Committed as found, defects documented rather than fixed: max_tokens=6000
truncates anything past ~6 minutes of audio, the page title is hardcoded,
and the schema still carries fields no consumer renders.

The four-check validator is the part worth keeping — the coverage-gap and
Swedish-number-grounding checks catch errors that timestamp and citation
checks structurally cannot.

Real transcripts and analyses stay out: this repo is public and the
recordings are a named person discussing a client's project. Only the
synthetic fixture is committed, which exercises all four checks with no
model call.

+## ADR-028 — Onboarding burst: pick likely-good videos, summarize them with a stronger model
+
+**Status:** Accepted (2026-06-11). **Refines ADR-018** (the connect-time burst) and **ADR-020**
+(recency-bounded auto-summarize). **Builds on ADR-022** (the endpoint chain), **ADR-023**
+(the discovery-time `videos.list` enrichment), and **ADR-021** (the shared transcript cache).
+Triggered by a Phase-1 investigation of the live pilot DB.
+
+**Context.** A new user's first session decides whether they return (the Stage-0 gate, ADR-016).
+The connect-time burst (ADR-018: summarize ≤`TAPIR_ONBOARD_SUMMARIZE_COUNT` newest videos so the
+feed isn't empty) *fires* in production, but a live-DB investigation of the second pilot user
+("Jonte") found it delivers a weak first impression for two reasons, and ruled out a third idea:
+
+1. **Junk picks.** Selection was pure newest-first (`NewestUnsummarizedVideoIDs`,
+   `ORDER BY published_at DESC`) with **no quality signal**. Jonte's live burst-3 were a
+   stock-ticker **livestream** + two regional news clips — newest, not best. The cheap signals
+   that *could* gate this (duration, live status) are fetched by ADR-023's `videos.list`
+   enrichment at discovery and then **thrown away**: the `videos.duration_s` column (migration
+   001) was never written.
+2. **Weakest model on the first impression.** All burst summaries ran on `koala/phi4-mini` — the
+   documented weak link (ADR-022 was born from its failures). The stronger, brain-validated
+   `iguana/gemma4-26b` was never used, even though the burst is only ~3 summaries.
+3. **Cached-first instant summaries — REJECTED.** The idea: skip the fetch, summarize
+   already-cached transcripts (ADR-021) instantly. The pilot numbers kill it — only **11 videos**
+   overlap between the two users (~3% of each ~350–400-video library), **0** cached-and-
+   unsummarized, and a new user's newest-20 unsummarized are **20/20 NOT cached**. Newest-first
+   and cached-first are structurally incompatible: fresh uploads are exactly what nobody has
+   fetched. An empty lever at pilot scale.
+
+**Decision.**
+1. **Persist `duration_s` at discovery.** `filterLowValue` (ADR-023) already has each candidate's
+   duration in hand; carry it onto the kept `domain.Video` and have `UpsertVideo` write it,
+   COALESCE-preserving a known value (the channel-title backfill stance, migration 014). No new
+   migration — the column exists. The connect-triggered discovery pass runs *before* the burst,
+   so a fresh user's candidates are enriched in time.
+2. **Junk-avoiding selection.** A new `OnboardBurstVideoIDs(userID, limit, minSeconds, maxSeconds)`
+   keeps the newest-first order but drops a video when its duration is *known* and outside
+   `[minSeconds, maxSeconds]` — `minSeconds` = `TAPIR_MIN_VIDEO_SECONDS` (60, the Shorts floor),
+   `maxSeconds` = new `TAPIR_ONBOARD_MAX_VIDEO_SECONDS` (default 14400 = 4h, to drop multi-hour
+   livestream VODs that pass the live filter once ended). A NULL duration is **unknown** — kept
+   (degrade-open) but ranked after known-good rows. **has-captions stays un-gateable pre-fetch**
+   (only knowable after a gate fetch or a ~0-probability cache hit); selection only *avoids
+   known-junk*, it does not *promise* captions.
+3. **Stronger model for the burst only.** `TAPIR_ONBOARD_SUMMARIZER_MODEL` (default
+   `iguana/gemma4-26b`) leads a burst-specific summarizer chain (onboard model first, then the
+   standard ADR-022 chain as resilience, deduped), wrapped in a burst-specific processor over the
+   *same* store/cache/sink — a pure wiring choice; the engine and ports are unchanged (ADR-003).
+   Empty or equal-to-primary collapses the burst back onto the shared processor.
+
+**Not a throughput change.** The caption rate gate (ADR-014) and the foreground priority lane
+(ADR-026) are untouched — same pacing, same cap. This changes *which* ≤3 videos the burst spends
+its fetches on and *which model* summarizes them, never how fast or how many. The engine's
+existing read-stored-first (ADR-021) is unchanged and still yields a free instant summary on the
+rare cache hit — we simply do not *select* for cache hits.
+
+**Consequences.** Better odds of a strong first session: the burst avoids the obvious junk and
+runs the better model on the one impression that decides return. The selection improvement is
+forward-looking — existing rows have NULL `duration_s` until their next discovery pass backfills
+it (lazy, like channel_title); a brand-new user benefits immediately because connect-discovery
+runs first. `duration_s` becoming live also unblocks future length-aware features (feed sorting,
+"long read" badges) for free.
+
+**Reversibility.** Pure config + wiring + one column write + one query, no migration.
+`TAPIR_ONBOARD_MAX_VIDEO_SECONDS=0` (and `TAPIR_MIN_VIDEO_SECONDS=0`) restores pure newest-first;
+`TAPIR_ONBOARD_SUMMARIZER_MODEL=""` collapses the burst back to the shared processor.
+Spec: `docs/specs/onboarding-wow-burst.md`.

+
+## ADR-029 — Stateless session cookie (survives restarts, browser-close, idle)
+
+**Status:** Accepted (2026-06-11). Triggered by pilot feedback: "lots of clicking to log in again
+on iPhone." Supersedes the in-memory session store in the ADR-011 login.
+
+**Context.** Three compounding causes made users re-login constantly:
+1. **In-memory session store** (`sessionStore` map) — wiped on every pod restart, so each deploy
+   logged everyone out. During the active build period that was ~15 logouts.
+2. **1-hour session TTL** — for a "check back tomorrow" reader, idle > 1h forced a re-login on
+   nearly every visit.
+3. **No cookie Max-Age** — a session cookie (deleted on browser/app close); iPhone Safari closing
+   the tab dropped it.
+Each re-login is the full Dex/Authentik redirect dance — many taps on mobile.
+
+**Decision.** Make the session **stateless**: the identity (subject + email) and an absolute
+expiry live INSIDE the existing HMAC-signed (HS256) cookie — no server-side table. Plus:
+- **30-day sliding TTL** (was 1h), re-signed on each request so an active user never lapses.
+- **Persistent cookie** (`Max-Age` set) so it survives browser/app close.
+The cookie is HttpOnly + Secure + SameSite=Lax; the HMAC (keyed by the stable ESO
+`tapir-session-secret`, which does NOT rotate per deploy) makes it tamper-proof. The payload is
+identity, not secrets — the OIDC access/ID tokens are still discarded after callback.
+
+**Consequences.** A deploy/restart no longer logs anyone out (proven by a test: a cookie issued by
+one instance is accepted by a fresh instance with the same secret); works across replicas for
+free. **Trade:** no server-side revocation — `logout` clears the cookie client-side, but a copied
+cookie stays valid until expiry. Accepted for the Stage-0 reader pilot; revisit (server-side
+revocation list, or shorter TTL + refresh) if it ever holds sensitive actions. Rotating
+`tapir-session-secret` invalidates all sessions — the global logout lever.
+
+**Not addressed here:** the tap-count of the IdP login page itself is Authentik's UX; with
+re-login now rare (30-day idle or explicit logout), it matters far less.

+
+## ADR-030 — Observability: slog timing + Prometheus metrics (AI-focused)
+
+**Status:** Proposed (2026-06-11). Issue #15. **Draft for review — no code yet.**
+
+**Context / requirements.** Nothing measures the activities that drive Tapir's performance and
+UX, and the Stage-0 eval gate (ADR-016) needs a *performance* dimension to sit beside the
+return-usage one. We need timing for: caption fetches (the scarce op), summarization (which model
+won, how long, fallbacks), Q&A latency, LLM token spend, and basic session/usage (request rate,
+latency by route, logins). Requirements:
+- R1: structured `slog` timing at each AI call site (human-readable, already the logging stack).
+- R2: Prometheus metrics for the same, scrapeable by the cluster's prometheus-operator.
+- R3: **AI metrics are the priority** — summarize latency by `model`/`outcome`/`fallback`,
+  caption-fetch latency by `outcome`, chat latency by `model`, and LLM `tokens` by model+kind.
+- R4: HTTP/session metrics via middleware — request count + latency by route, logins.
+- R5: bounded label cardinality (no per-user, no raw-path labels).
+- R6: `/metrics` must NOT be publicly exposed.
+
+**Decision / architecture.**
+1. **New package `internal/metrics`** owns all Prometheus collectors + a typed API
+   (`ObserveSummarize`, `ObserveCaptionFetch`, `ObserveChat`, `RecordTokens`, `IncLogin`,
+   `HTTPMiddleware`, `Handler`). Adapters call this API; they never import prometheus types.
+2. **New dependency `github.com/prometheus/client_golang`.** Justification: it is *the* standard
+   Go Prometheus client and the cluster already runs prometheus-operator; hand-rolling exposition
+   is not worth it. (Needs the dep-justification note in the commit per repo rules.)
+3. **The copied `llm` package stays stdlib-only (ADR-004).** It must not import `internal/metrics`.
+   Token usage is surfaced via an **optional callback** `llm.WithUsageHook(func(model string, prompt, completion int))`
+   set at wiring time (`buildSummarizer`/`buildChat`) to `metrics.RecordTokens`; `llm.Client` only
+   gains parsing of the response `usage` block. Our own adapters (`summarizer`, `youtube`, `chat`)
+   may import `internal/metrics` directly.
+4. **HTTP middleware** reads `r.Pattern` AFTER routing (Go 1.22 sets it during ServeMux match), so
+   the `route` label is the bounded registered pattern (`GET /v/{videoId}`), satisfying R5;
+   unmatched → `other`.
+5. **Dedicated metrics port** (`TAPIR_METRICS_ADDR`, default `:9090`) served by a second
+   `http.Server` in `cmdServe`; `/metrics` is never on the public app mux (R6). A **PodMonitor**
+   in `mathias/infra` scrapes it; the deployment exposes the port.
+6. **slog** elapsed fields are emitted alongside each metric at the call sites (R1).
+
+**Hook points (where the instrumentation lands).**
+- `summarizer.Summarize` — per-endpoint timing + outcome (`success`/`parse_error`/`error`) + fallback flag.
+- `youtube.FetchTranscript` — fetch timing + outcome from `domain.Transcript.Source`.
+- `chat.Service` answer — timing by model.
+- `llm.Client.Complete` — parse `usage`, fire the usage hook.
+- `oidc.handleCallback` — `IncLogin`.
+- `cmdServe` — wrap `Router()` in `metrics.HTTPMiddleware`; start the metrics server.
+
+**Out of scope / later.** Persisting per-summary latency into Postgres for `tapir report`
+(derive UX latency — publish/discovery → summary — from existing timestamps first; only persist
+op-latency if the scrape proves insufficient). SPA view (#16) and visual refresh (#17).
+
+**Reversibility.** Additive: a new package + middleware + a metrics port. Removing the PodMonitor
+stops scraping; the app is unaffected. No schema change.
+
+**Next steps (gated):** on approval of this ADR → BDD scenarios (`docs/use-cases/observability.feature`
++ scenario-coverage map) → TDD → implement → SemVer + docs + PodMonitor.

+## ADR-031 — SPA-like reader: inline-expand summary + Q&A in the list (HTMX, no framework)
+
+**Status:** Proposed (2026-06-12). Issue #16. **Draft for review — no code yet.**
+
+**Context / requirements.** The reader is multi-page: a list of compact cards (`/`), then a
+navigation to a separate detail page (`/v/{id}`) for the full summary + the docked chat (ADR-027).
+It feels less fluid than a single integrated view. We want the full summary AND the per-video
+Q&A to open **in place in the list**, no page hop. Requirements:
+- R1: clicking a summarized card expands it in place to the full summary (summary/highlights/
+  takeaways) + the chat dock; a collapse returns it to the compact card.
+- R2: **no SPA framework** — stay HTMX + Templ (ADR-003); reuse existing fragments, not a rewrite.
+- R3: **progressive enhancement** — with JS off, the card link still navigates to `/v/{id}`
+  (the detail page stays as the no-JS + deep-link surface). Nothing becomes JS-only.
+- R4: only **summarized** cards expand; pending/rate-limited/no-caption cards keep their current
+  footer behaviour (Summarize button, waiting/none states).
+- R5: chat inside an expanded card works exactly as on the detail page (reuse `chatReveal`/
+  `chatSection` + the existing `/v/{id}/chat` endpoints, unchanged).
+
+**Decision / architecture.**
+1. **Reuse the existing fragments.** `summaryBody(r)` and `chatReveal(videoID)` already exist and
+   render the detail page; a new `expandedCard(r, chatEnabled)` composes the compact header + a
+   collapse control + `summaryBody` + `chatReveal`. `DetailPage` is refactored to also compose
+   `summaryBody` so the two never drift (DRY).
+2. **Two fragment endpoints** (mirroring the existing list/status HTMX fragment pattern):
+   `GET /v/{videoId}/expand` → `expandedCard`; collapse reuses the existing compact `VideoCard`
+   via `GET /v/{videoId}/card`. Both are list-card `<li>` fragments with the SAME `id`
+   (`video-{id}`), swapped `outerHTML` — same mechanism as `processingCard`/`VideoCard` today.
+3. **The compact card's title/"Read" affordance** becomes `hx-get=/v/{id}/expand`,
+   `hx-target=#video-{id}`, `hx-swap=outerHTML`, with `href=/v/{id}` as the no-JS fallback (R3).
+   The expanded card's collapse control is the inverse (`hx-get=/v/{id}/card`).
+4. **Only when `r.Summarized`** does the expand affordance render (R4); the other states are
+   unchanged.
+5. **v1 does NOT push the URL** (`hx-push-url`) — expand/collapse is ephemeral list UI state; the
+   detail page remains the deep-link/shareable URL. Deep-linking the open state via `hx-push-url`
+   is noted as a later option (needs list-state restore on back).
+
+**Out of scope / later.** URL push / deep-linkable open state; the visual refresh (#17) — though
+the expanded-card markup is where #17's TUI/charm styling will land, so they pair.
+
+**Reversibility.** Additive: two fragment endpoints + one templ + an affordance swap on the
+compact card. Removing the affordance reverts to plain list→detail navigation; the detail page is
+untouched. No schema change.
+
+**Next steps (gated):** on approval → BDD (`docs/use-cases/inline_expand.feature` + coverage
+map) → TDD → implement → SemVer + docs.

+## ADR-032 — Visual refresh: one charm-reader layout, light + dark themes
+
+**Status:** Proposed (2026-06-12). Issue #17. **Draft for review — no code yet.** Follows the
+sketch-first explore step (3 throwaway mockups in `docs/sketches/`, screenshotted for review).
+
+**Context / decision.** The UI is flat. From the mockups, directions **B (light reader + charm)**
+and **C (dark cozy terminal)** are the SAME layout — readable sans body, monospace meta, charm
+palette accents, lipgloss-style bordered cards — in two palettes. Direction A (full-monospace TUI)
+is dropped as too heavy to read long summaries. Decision: ship that one layout with **both a light
+theme (B) and a dark theme (C)**, user-toggleable, defaulting to the OS preference.
+
+**Requirements.**
+- R1: one set of markup/structure; the two themes are pure palette (CSS variables), no duplicate templates.
+- R2: a **theme toggle** persisted across visits; default to `prefers-color-scheme` when no choice stored.
+- R3: charm language in both — mint/purple/pink accents, mono meta + section labels, lipgloss
+  bordered/gradient cards, the (fixed) ASCII tapir; readable sans body.
+- R4: style the existing pieces — list, compact card, **expanded card incl. the already-present
+  video embed (ADR-031/summaryBody)**, detail page, chat dock, the queue note, the charm spinner.
+- R5: WCAG-AA contrast for body text in BOTH themes; keep `prefers-reduced-motion` (already honoured).
+- R6: stay HTMX+Templ; no CSS framework.
+
+**Architecture.**
+1. **Palette as CSS variables.** `:root` holds the light (B) tokens; `:root[data-theme="dark"]`
+   holds the dark (C) tokens; a `prefers-color-scheme: dark` media block sets the dark tokens when
+   no explicit `data-theme` is set. All component CSS references variables only (R1). The existing
+   `CharmMint/Purple/Pink/Cream/Dim` Go consts remain the source for the spinner's inline colours.
+2. **Theme toggle** = a small inline script (a dozen lines, no framework) in `Layout`: on load,
+   apply stored theme (localStorage) or fall through to the media query; a header toggle button
+   flips `data-theme` on `<html>` and stores it. This is the one new bit of JS; everything else
+   stays server-rendered + HTMX. (Considered: cookie + server-render — rejected, a full round-trip
+   per toggle is clunky for a pure presentation flip.)
+3. **Scope = the `styleTag` CSS in `view.go`** (the single style source) plus tiny class hooks in
+   the templ where needed; content/structure are unchanged, so existing view tests keep passing.
+
+**Verification.** The deployed UI is behind auth (web-shot can't log in), so visual review is via
+the mockups now + a styled full-set mockup screenshot before merge, then a live eyeball on device.
+Automated tests stay structural/behavioural (theme tokens present, toggle persists, expanded card
+embeds the video, no-JS still renders a readable default) — colours are not unit-tested.
+
+**Reversibility.** A CSS theme swap + one small script + a few class hooks; revert `styleTag` to
+roll back. No schema, no structural change.
+
+**Next steps (gated):** on approval → BDD (`docs/use-cases/visual_theme.feature` + coverage map)
+→ TDD → implement → SemVer + docs.

+### Connect-time onboarding burst (ADR-018 → ADR-028)
+
+On a successful YouTube connect, `ConnectHandler` enqueues a connect-triggered discovery pass;
+the `discoveryTrigger` runs that pass and then fires the **onboarding burst** — a third entry path
+that summarises up to `TAPIR_ONBOARD_SUMMARIZE_COUNT` (default 3, hard-capped) of the new user's
+videos so the first session is not empty. The burst still flows through `globalFetchGate` (it is
+not a throughput change); ADR-028 sharpened *which* videos and *which model*:
+
+- **Selection** is `OnboardBurstVideoIDs`, not pure newest-first. It keeps newest-first order but
+  excludes a video whose **known** duration is outside `[TAPIR_MIN_VIDEO_SECONDS,
+  TAPIR_ONBOARD_MAX_VIDEO_SECONDS]` (drops Shorts and multi-hour livestream VODs). An unknown
+  (NULL) duration is degrade-open — kept, but ranked after known-good rows. The connect-triggered
+  discovery pass runs *before* the burst, and ADR-023's `videos.list` enrichment now **persists**
+  `duration_s` (instead of discarding it after the Shorts filter), so a fresh user's candidates
+  carry a duration in time for selection.
+- **Model**: the burst runs through a dedicated summarizer chain led by
+  `TAPIR_ONBOARD_SUMMARIZER_MODEL` (default `iguana/gemma4-26b`, the stronger local model), with
+  the standard ADR-022 chain following as fallback. This is a wiring choice — a second
+  `engineProcessor` over the same store / transcript cache / sink; the engine and ports are
+  unchanged. Empty / equal-to-primary collapses it back onto the shared processor.
+
+`has-captions` is deliberately **not** a selection signal — it is only knowable after a gate fetch
+(or a ~0-probability cache hit at pilot scale), so the burst can avoid known-junk but cannot
+promise captions. Cached-transcript-first selection was investigated and rejected (ADR-028:
+~3% cross-user overlap).

+# Spec — Onboarding "wow" burst: better picks, stronger model
+
+**Repo:** tapir · **Size:** medium · **Solo session** (not a swarm).
+
+> **Status: built (v0.25.0, ADR-028).** This supersedes the original investigate-first brief
+> (committed as the prior version of this file): Phase 1 was run against the live pilot DB and its
+> findings are folded into "Why this exists" below; Phase 2 was built as described here. The one
+> brief lever NOT built — the honest "the rest fill in over the coming days" framing copy — is
+> listed under *Explicitly NOT in this slice*.
+
+**Why this exists.** A new user's first session decides whether they return (the Stage-0 gate,
+VISION.md). On connect, Tapir fires a capped burst (≤`TAPIR_ONBOARD_SUMMARIZE_COUNT`, default 3)
+that summarizes the user's newest unsummarized videos so the feed isn't empty (the burst itself
+works — wired in `cmd/tapir/discovery.go` → `cmd/tapir/main.go` `onboard`). A Phase-1
+investigation of the live pilot DB found the burst *fires* but delivers a **weak first
+impression** for two concrete reasons, and ruled out a third idea:
+
+1. **Picks are junk.** Selection is pure newest-first (`videos.NewestUnsummarizedVideoIDs`,
+   `ORDER BY published_at DESC`) with **zero quality signal**. Pilot user "Jonte"'s live burst-3
+   were a stock-ticker **livestream** + two regional news clips — the newest, not the best.
+2. **Weakest model on the first impression.** All of Jonte's summaries ran on
+   `koala/phi4-mini` (the documented weak link — ADR-022 was born from its failures). The
+   stronger, brain-validated `iguana/gemma4-26b` was never used for the burst.
+3. **Cached-first is empty at pilot scale — REJECTED.** The idea (summarize already-cached
+   transcripts instantly, zero fetch) dies on the numbers: only **11 videos** overlap between the
+   two pilot users (~3% of each library), **0** cached-and-unsummarized, and a new user's
+   newest-20 unsummarized are **20/20 NOT cached** — newest-first and cached-first are
+   structurally incompatible (fresh uploads are exactly what nobody has fetched yet). Not built.
+
+This is a **curation/latency problem for ~3 videos, NOT a throughput/429 problem** — fetching 3
+captions is nowhere near the rate limit. Nothing here fetches harder or pressures the rate gate;
+it picks the right few videos and runs a better model on them.
+
+Read `CLAUDE.md`, `DECISIONS.md` (esp. ADR-014, ADR-018, ADR-020, ADR-021, ADR-022, ADR-023,
+and the new **ADR-028**), and `VISION.md` (the Stage-0 gate) first. TBD — commit directly to
+`main`, one logical change per commit, conventional commits, `task check` green before each
+commit, `templ generate` if any view changes (none expected).
+
+## Decisions already made (do not reopen)
+- **Not a throughput change.** The caption rate gate (ADR-014) is untouched — same pacing, same
+  priority lane (ADR-026). This slice changes *which* ≤3 videos the burst spends its fetches on
+  and *which model* summarizes them, never how fast or how many.
+- **Cached-first is dropped** (ADR-028, the 3% overlap). The engine's existing read-stored-first
+  (ADR-021, `resolveTranscript`) stays — it already gives a free instant summary on the rare
+  cache hit, transparently. We do not *select* for cache hits.
+- **has-captions is not a pre-fetch signal.** It is only knowable after a gate fetch (or a cache
+  hit, ~0 for new videos). Selection can only *avoid known-junk* (Shorts/live/over-long) — it
+  cannot *guarantee* captions. The spec is honest about this: better odds, not a promise.
+- **No credentialed caption fetch** (ADR-010/ADR-026 dead end). **No client extension.**
+
+## 1. Persist `duration_s` at discovery (the enabling change)
+The `videos.duration_s` column exists (migration 001) but is **never written** — ADR-023's
+`filterLowValue` (`internal/adapters/youtube/youtube.go`) already fetches each candidate's
+duration via the cheap quota `videos.list` call, uses it to drop Shorts/live, then **discards
+it**. Stop discarding:
+- Add `DurationSeconds int` to `domain.Video`.
+- In `filterLowValue`, set `DurationSeconds` on each kept video from the `videos.list` `meta`.
+- `UpsertVideo` writes `duration_s`, **COALESCE-preserving** a known value (never overwrite a
+  real duration with 0/unknown), mirroring the `channel_title` backfill stance (migration 014).
+- No new migration — the column is already there.
+
+Consequence: a fresh user's connect-triggered discovery pass runs **before** the onboard burst
+(`Enqueue`: `run()` then `onboard()`), so duration is populated for the burst's candidates at
+connect. Existing rows backfill on their next discovery pass; until then their `duration_s` is
+NULL and treated as "unknown" (§2).
+
+## 2. Junk-avoiding burst selection
+New store method, RLS-scoped via `withUser`:
+
+```
+OnboardBurstVideoIDs(ctx, userID string, limit, minSeconds, maxSeconds int) ([]string, error)
+```
+
+- Same base as the old `NewestUnsummarizedVideoIDs`: the user's videos with no summary yet,
+  `ORDER BY published_at DESC NULLS LAST, seen_at DESC`, `LIMIT limit`.
+- **Exclude known-junk**: a row is dropped only when `duration_s IS NOT NULL` **and**
+  (`duration_s < minSeconds` OR `duration_s > maxSeconds`). A NULL duration is **unknown** — kept
+  (degrade-open: never starve the burst because metadata is missing), but ordered *after* rows
+  with a known-good duration so a freshly-enriched good pick wins when both exist.
+- `minSeconds` reuses `TAPIR_MIN_VIDEO_SECONDS` (default 60 — the Shorts floor, ADR-023).
+  `maxSeconds` is new: `TAPIR_ONBOARD_MAX_VIDEO_SECONDS` (default 14400 = 4h) — drops the
+  multi-hour livestream VODs that pass the live filter once ended.
+- `minSeconds<=0` and `maxSeconds<=0` each disable that bound (so `0/0` == the old
+  newest-first behaviour, the reversibility lever).
+- The burst switches to this method; `NewestUnsummarizedVideoIDs` is removed (fully superseded —
+  `OnboardBurstVideoIDs(., 0, 0)` is identical pure-newest behaviour).
+
+## 3. Stronger model for the burst
+The burst summarizes only ≤3 videos, so a slower, stronger model is affordable exactly here.
+- New config `TAPIR_ONBOARD_SUMMARIZER_MODEL` (default `iguana/gemma4-26b` — the brain-validated
+  homelab general-purpose model, already the ADR-022 fallback).
+- Build a **burst-specific summarizer chain** that puts the onboard model **first**, then the
+  standard chain (primary → local fallback → cloud) as resilience, deduped. Wrap it in a
+  burst-specific `engineProcessor` reusing the same store/transcript-cache/sink — a pure wiring
+  choice, engine and ports unchanged (Clean Architecture, ADR-003).
+- The `onboard` closure uses the burst processor instead of `app.Processor`.
+- **Collapse cleanly**: when `OnboardSummarizerModel` is empty or equals `SummarizerModel`, the
+  onboard path reuses `app.Processor` (no separate chain) — the reversibility lever.
+- Local-first preserved: the onboard model is a local alias; the cloud endpoint stays last in the
+  chain, so a client/NDA deployment with `TAPIR_CLOUD_FALLBACK_MODEL=""` keeps burst content
+  local too.
+
+## 4. Behaviour spec + docs
+- Add scenarios to `docs/use-cases/connect_account.feature` (the connect → burst flow): burst
+  skips a too-long/live video in favour of a reasonable-length one; burst summarizes with the
+  stronger model first. Map them in `scenarioCoverage` so `TestScenarioCoverage` stays green.
+- Update `docs/architecture/architecture.md` (the onboarding-burst section) to describe the
+  junk-avoiding selection + the burst model override.
+- ADR-028 in `DECISIONS.md` records the rationale (incl. the rejected cached-first lever).
+
+## Success criteria
+- `task check` green (fmt, vet, lint, `go test -p 1 ./...`).
+- A unit test proves `OnboardBurstVideoIDs` drops a known too-long / sub-min video and keeps a
+  good one, newest-first, RLS-scoped, unsummarized-only.
+- A test proves discovery persists `duration_s` and does not clobber it on re-upsert.
+- A test proves the burst chain leads with the onboard model (then the standard chain).
+- Config defaults + bounds tested (`OnboardMaxVideoSeconds`, `OnboardSummarizerModel`).
+- No change to the rate gate, fetch pacing, or burst cap. `0/0` + empty model == prior behaviour.
+
+## Explicitly NOT in this slice
+- Cached-first selection (rejected, ADR-028).
+- Any caption-availability *guarantee* (impossible pre-fetch).
+- **Honest "taster" framing copy** ("summaries of a few of your videos to get you started — the
+  rest fill in over the coming days"). A good lever from the original brief, but it's a UI/copy
+  change with no backend dependency; deferred to a UI pass, tracked as an issue.
+- Backfilling `duration_s` for existing rows via a migration (it backfills lazily on discovery).
+- Return-nudges / digests (ADR-020: poisons the unprompted-return signal).
+- Raising fetch throughput, multi-IP, or Whisper (out of scope; the gate is deliberate).

An init script in `<head>` applies the stored choice before paint (no flash). Charm touches: monospace meta lines, accent uppercase section dividers with a trailing rule, pill buttons, a lifted/accent-edged expanded card.

List order is now `summarized-first, published_at DESC NULLS LAST`. Copy reframed for honest scarcity: pipeline bar reads "N ready · M in queue · K no captions" (no "fetching soon"); a gradual-fill note explains the rate limit; the nudge verb is "Summarize" (not "Summarize now"); the queued card says "summarizing shortly"; the empty-connected state drops the impossible `tapir run` instruction. Detail leads with Takeaways. Filters slimmed (no date pickers; hidden when empty); watched/skipped segmented; back link on detail; empty terms checkbox removed. | Make the sparse reality legible and honest instead of implying abundance/imminence; bound auto load so the back-catalogue doesn't re-drive the caption gate.

+# spike-media — the `/bygge` toolchain, recovered
+
+Throwaway spike tooling for #28 (upload → transcript → takeaways). Committed
+because it was found in `tmpfs` one reboot from gone, not because it is finished.
+
+Nothing here is wired into tapir. No database, no HTTP handler, no ADR.
+
+## What produced `/bygge`
+
+The prototype at `tapir.d-ma.be/bygge` was **not** hand-built, which the epic and
+the first round of spike issues both got wrong. It came from these three scripts:
+
+```
+IMG_1233.mov --transcode.yaml--> IMG_1233.web.mp4   (k3s Job, h264, +faststart)
+IMG_1233.wav --whisper---------> IMG_1233.sv.srt    (interactive — the one manual step)
+IMG_1233.sv.srt --analyze_srt.py--> analys.json     (berget/mistral-medium, temperature=0)
+analys.json + video --build_page.py--> page HTML
+```
+
+The reference analysis was produced by **`berget/mistral-medium`** — a mid-tier
+cloud model, not a frontier one. That matters when judging what a local model
+has to clear: the bar is mistral-medium, and it should be re-run as the control
+arm rather than excluded.
+
+## The validator is the valuable part
+
+`analyze_srt.py` grades its own output on four checks. Two of them catch classes
+of error that timestamp- and citation-checking cannot:
+
+| Check | Catches |
+|---|---|
+| citation exact / **partial** / absent | Paraphrase presented as a quote. Three tiers, because `alternativ` citations legitimately stitch non-contiguous passages — a strict substring test fails the reference output. |
+| `TALET … FINNS INTE I CITATET` | A wrong number carried by a *verbatim* citation and a *real* timestamp. Converts Swedish number-words to digits first. It caught `45×230` where the transcript said `220`. |
+| `TACKNINGSLUCKA` | Spans of the clip no section covers. **The recall term** — without it an empty analysis scores perfectly on every other check. |
+| timestamp exists in the SRT | Fabricated seek targets. Near-solved: 74/75 on the reference, because the model copies the cue starts it was handed. |
+
+## Known defects — read before running
+
+- **`max_tokens: 6000` is too low.** The 4-minute reference analysis is ~4,700
+  output tokens, i.e. ~78% of budget. A 10-minute clip truncates for every model,
+  and truncation reads as a JSON-discipline failure if you are not counting
+  tokens. Record `finish_reason` and separate `truncated` from `malformed`.
+- **`build_page.py` hardcodes the title** (`"Jonas – genomgång av tillbyggnad"`).
+- **The schema carries fields nothing renders** — `projekt.sammanfattning`,
+  `projekt.skede`, `avsnitt.bildtid`, `avsnitt.bildmotiv`, `material[]`,
+  `oklart[]` — left over from an earlier still-frame/markdown output that
+  `build_page.py` replaced. They are paid for in output tokens on every run.
+- **Speaker attribution is inferred, not diarized.** The output attributes
+  statements by name from an SRT with no speaker labels. All four checks above
+  are blind to a misattribution.
+- **The web encode does not downscale.** The source is 720×1280; `-preset
+  veryfast -crf 24` on handheld motion is what makes it ~5 Mbps, not the
+  resolution. The lever is the preset.
+
+## Fixtures
+
+`fixtures/fake.sv.srt` + `fixtures/fake.analys.json` — a synthetic 7-cue Swedish
+construction walkthrough with planted numbers. No real people, no real project.
+It exercises the parser and all four validator checks **without a model call**,
+which is what makes it usable in a test.
+
+## Why the real artifacts are not here
+
+**This repo is public.** The prototype's transcript and analysis are a verbatim
+recording of a named person discussing a client's building project — private
+third-party content, and exactly the class of data #28 calls out as the reason
+uploaded transcripts cannot live in the shared `transcripts` table.
+
+So `IMG_1233.sv.srt`, `payload.json` and the model-comparison runs stay out of
+git here. That leaves `/bygge` without a versioned source of truth, which is a
+real gap and a decision for #28: a private repo, an encrypted blob, or accepting
+that the reference artifacts live outside version control.
