Narrow “PSI damage” to the handled CRC case.
The importer counts and skips only PAT/PMT sections that fail psi::crc_ok. Other malformed sections can be silently rejected, and incomplete sections remain buffered until more data arrives. The current wording implies broader handling than #4584 provides.
Suggested wording
-- holds it at section granularity for PSI (#4584): a damaged unit is refused whole, never half
- published, and counted, and nothing else about the feed changes. PSI damage
- is already handled.
+- holds it at section granularity for bad-CRC PAT/PMT sections (#4584): a bad-CRC
+ section is refused whole, never half published, and counted, and nothing else
+ about the feed changes. Bad-CRC PAT/PMT damage is already handled.🤖 Prompt for AI Agents

Reviewed commit: ba10d85
P2: Preserve the remaining Programs reassembly work before deleting the quest. The deleted quest/m1/ts-psi-reassembly.md:55–56 still has an unfinished edge documented in #4584's final review. At this head, programs.rs:86–88 seeds only the completed table. When that packet also starts a longer next-version PAT, the scanner retains its partial section but the fresh importers ignore its non-PUSI continuation. A PMT-PID remap and following media are then missed until another PAT repetition. The surviving TS quests do not cover this handoff. Retain a narrow follow-up quest for preserving the parser state and testing this transition before removing the completed plan.
Direction: the demux/CRC cleanup is otherwise justified; keep the long-PMT export round-trip separate, and leave PAT_error/PMT_error in TS import health.
Verification: inspected all five changed files, current handoff/parser code, planned tests, and prior review. The updated files' repository links resolve. Head Quest and Test passed; Check was still running. No local Rust tests or quest check were run because those tools are unavailable.
