The v2 delta engine: real lifecycle transitions and amendment detection, replacing the v1 retrofit's "always NEW_LISTING" limitation - see AGENTS.md "Delta engine v2" for the full technical reasoning.
STATUS_CHANGE events: a tender that moves to a different estado_compra since it was last seen (e.g. upcoming -> awarded) is now reported as STATUS_CHANGE with previousEstado set, instead of a fresh NEW_LISTING under its new estado.UPDATED events: a tender whose content changed (monto, renglon, date, any other field) while staying in the same estado is detected via a sha1 content fingerprint (contentHash) and reported as UPDATED - at zero extra HTTP requests, since every field is already inline in this actor's one listing fetch per page.eventTypes input: narrows delta-mode delivery to a subset of NEW_LISTING/STATUS_CHANGE/UPDATED.contentHash and previousEstado output fields; a second dataset view ("Status changes & amendments").- Apache-2.0

- Delta state shape:
src/state.ts replaced the v1 per-estado { seenIds, lastRunAt } map with one flat, cross-estado map (idCompra -> { estado, hash }) - the per-estado design could not itself distinguish "genuinely new" from "moved here from another estado", which is exactly what STATUS_CHANGE needed to know. Not backward compatible: a v1-shaped state is treated as absent, not migrated - an existing scheduled task's next run re-baselines (see AGENTS.md).
- Pricing: single
result event at $0.003/record (was $0.001, uncharged distinction). No result-summary tier - unlike sibling fleet actors, every Tucuman record already includes full detail at identical extraction cost, so a cheaper listing-only tier would not reflect any real cost difference (disclosed in README).
is_new keeps its exact v1 meaning (never seen before, under any estado) - not redefined to mean "something changed".
- Production
start script pointed at start:dev (tsx), which Apify's production image cannot run (npm install --only=prod strips tsx). Switched to the prebuilt dist/main.js and stopped gitignoring dist/ so the build actually ships.
