The 'Oldest first' order sorts by PUB DATE, which breaks on Scribl's
migrated podiobooks feeds (messy/all-equal dates). New order value
'reverse' = feed position DESC with a date-DESC tiebreak — dates are
not involved, so nothing can break.
- services.OrderEpisodes: THE single order source of truth (§0 items
3+5a). The four surfaces (sequence JSON, reader chain context, SSR
page list) previously carried three near-identical handwritten
comparators — all now route through one generic helper. The SSR page
list gains a SortDate key (lexical 2006-01-02) so the pub-date
tiebreak is actually chronological; the old comparator compared
'Jan 2, 2006' display strings alphabetically (latent drift bug).
- Dropdown becomes four options: Feed order / Feed order (reversed) /
Oldest first (pub date) / Newest first (pub date).
- Serial suggestion button renamed 'Reverse feed order' (sets reverse,
not oldest) and its response out-of-band-swaps the order select
(PodcastOrderSelectOOB — same mechanism as Download All's policy
select), so the dropdown mirrors the server state immediately.
- Validation: oneof=native reverse oldest newest everywhere.
- Tests: reverse binds via the form wire; messy-dates sequence
returns 3,2,1; existing reorder-safety stays green.
WHY: downloads needed manual refreshes to see progress; the 204 +
HX-Trigger event indirection missed its listener, and the worker
buffered whole enclosures so no progress existed to show.
- Worker streams enclosures to disk through a counting loop (64KiB
chunks, scheme/redirect/size guards preserved) with an in-memory
per-episode progress snapshot (received/total; total from
Content-Length, seeded by the feed's declared length). Deliberately
transient — the DB row state remains the durable truth.
- Episode-list renderer seam: the router injects a closure into
PodcastHandler (handlers can't import templates — MediaDetail cycle)
so htmx download/retry/Download All/refresh/order/policy actions
answer with the REFRESHED partial directly (200, hx-target=
#episode-list) — no events to miss. Non-HX callers keep JSON; tests
without a renderer keep 204+trigger.
- Polling tightens to 2s while downloads are active; downloading rows
render a percentage bar + MB counter (quote-free inline style per
templ gotcha #8) or an indeterminate bar when the server sends no
length.
- Issue #3: Download All (button AND the add-feed checkbox) flips the
CALLER's subscription policy to 'all' — per-user, never global (D6:
files shared, policies not) — and the auto-download select
out-of-band-swaps so the dropdown shows what the user is getting.
They can turn it down afterwards; the flip is honest communication,
not coercion (user-approved 2026-10-29).
PINs: Download All with HX answers 200 + episode-list + oob select and
flips newest → all; add-feed download_all sets policy all.
The §8 surface, wired through main.go → router.Config →
/api/podcasts (JWT). Scoping is the engine's (D20): lookups outside the
caller's scope simply return no rows → 404; the only Go-level checks
are explicit-argument authorization (AddFeed's library +
allow_member_feeds gate) and the admin role on feed deletion.
Endpoints: POST/GET /feeds (add: fetch+parse+upsert+subscribe, optional
download_all; list: subscriptions + episode counts + facet values
computed in Go — feed counts are tens), GET /feeds/:id (detail with
download states + gap count), PUT/DELETE /subscription (the ONLY
user-writable podcast state, D9; unsubscribe retains files per D6),
POST /refresh, POST /episodes/:eid/download (+ episode_ids[] bulk and
eid='all' = Download All, exactly the non-downloaded set),
PUT /order (D5 per-user override in the reader_settings KV —
podcast_order:<feed_id>; 'native' deletes the row so default and
explicit choice are indistinguishable), GET /sequence (effective order
— override applied, native fallback — DOWNLOADED-only with the gap
list; this payload powers web chain mode and, per §15, the future
media3 queue), GET /search (subscription-scoped feed + episode search
covering un-downloaded and historical rows, D14), DELETE /feeds/:id
(admin; best-effort file removal, cascade deletes rows).
Gap definition (countGaps): an un-downloaded episode with a downloaded
episode AFTER it in list order — the D8 'middle episodes missing'
banner condition.
