mode: page-discovery
startUrl: https://www.lidl.de/c/online-prospekte/s10005610

1. browser_open startUrl. It's a JS-rendered listing with no useful server
   HTML — the browser is required for this one step. No cookie/store
   selection is needed to see the cards; if a cookie or "Filiale wählen"
   dialog is visible it doesn't block reading the links underneath, but
   dismiss it if it does.
2. browser_snapshot and take the href of any one visible "Aktionsprospekt"
   card link — matches
   /l/prospekte/aktionsprospekt-{DD-MM-YYYY}-{DD-MM-YYYY}-{id}/ar/0
   (the trailing id is a few random hex/alnum characters, not guessable —
   always read it from the page, don't construct it). Extract the slug:
   the path segment after /prospekte/ and before /ar/0, e.g.
   "aktionsprospekt-03-08-2026-08-08-2026-687527".
3. browser_open
   https://endpoints.leaflets.schwarz/v4/flyer?flyer_identifier={slug}
   directly. This is a JSON API response, not an HTML page — read the
   already-loaded body as text (same pattern as any JSON-as-text page);
   do not use browser_wait or inspect the DOM, there is nothing to render
   or click. This one response gives you the bootstrap flyer's own pdfUrl
   plus a relatedFlyers array listing every other currently active
   publication (both the other weekly editions and every current standing
   catalogue) with their own slug and pdfUrl.
4. For each entry (the bootstrap flyer plus everything in relatedFlyers),
   confirm its own validity by calling
   https://endpoints.leaflets.schwarz/v4/flyer?flyer_identifier={its slug}
   (browser_open, read as text, same as step 3) UNLESS you already have
   its offerStartDate/offerEndDate — the relatedFlyers array's own
   startDate/endDate fields are NOT the offer validity (see note below),
   don't use them for dates, only for discovering which slugs exist.
5. Read validity from the human-readable slug/title, not the JSON date
   fields (see investigation notes for why): the slug encodes
   {DD-MM-YYYY}-{DD-MM-YYYY} directly, and the title field repeats it as
   "DD.MM.YYYY – DD.MM.YYYY" — both only exist on the 3 weekly
   "Aktionsprospekt" editions. A flyer whose title/slug has no such date
   range (the standing catalogues) has no fixed validity — treat it as an
   open-ended catalogue instead (see step 6).
6. Reminder eligibility — decide by whether the flyer has a parseable
   {DD-MM-YYYY}-{DD-MM-YYYY} validity range, not just by name:
   - The 3 "Aktionsprospekt" weekly editions: call get_cycle_status to
     find which of the 3 dates is the currently missing cycle and queue
     that one with reminderId from get_cycle_status. Queue the other 2
     with the SAME reminderId — it's the same recurring series just a
     different week, not ambiguous, don't leave it null.
   - Everything else (no parseable weekly date range — recipe magazines,
     "price leader" posters, any other rotating standing catalogue):
     reminderId=null is correct here, there is no matching reminder for
     these. Queue as an open-ended catalogue (no validityFrom/validityTo)
     using the flyer's own title/name and "status":"current" as evidence
     it's a real, currently-live sales publication — official wording
     like "dauerhaft" (permanently) on these catalogues is exactly the
     kind of open-ended cue the evidence contract accepts. Reject only if
     a candidate is clearly not a sales publication (legal/corporate
     document) — these observed so far (recipe magazine, price-leader
     poster) clearly are genuine offer publications.
7. inspect_pdf then queue_pdf each pdfUrl (assets.leaflets.schwarz,
   confirmed stable and unauthenticated — no token/expiry to worry about,
   safe to queue as-is).
8. offerEvidence: "Official leaflets.schwarz catalogue API
   (endpoints.leaflets.schwarz/v4/flyer), confirmed application/pdf via
   inspect_pdf." Cite the flyer's own name/title from the JSON as
   corroborating evidence.

No store/Filiale was selected to reach this data — the region code visible
in page URLs (e.g. lf=HHZ) appears to be a default, not a deliberate pin.
Single reference region for now, consistent with other retailers in this
set; multi-region coverage deferred.
