A second wave: Copilot flagged three more red-tagged bugs at 09-24T20:54Z, all in the compression-ratio-4 retrofit specifically — cache-miss placeholders uploaded without a completeness check (nondeterministic top-k on a missing cache), valid_end_tensor left unscaled by the ratio (up to 4x-too-wide score bound on partial chunks), and the fused all-gather still comparing token units against compressed-tile counts (wrong cache slabs gathered, or a device assertion). None addressed by reply or by commit — the PR's last commit is 09-24T16:35Z, four and a half hours before the findings landed. jmitrovicTT approved anyway at 08:14Z this morning, ~11 hours later, having left exactly one comment of his own first: an unrelated style nit (assert vs. return) on a test file. Also still open: pavlejosipovic's three 09-21 asks (dedicated op-level tests, green BH sanity/nightly, hardcoded-32→tile constants). jmitrovicTT's own 08:22Z comment — \"just pls run relevant subsets of L2 nightly and Blackhole e2e on this branch\" — reads as an admission the BH-sanity ask still hasn't happened, and doesn't touch the other two."

"text": "540 recovered fragments resolve to a minimum of 500 iron semi-products — over a tonne total, the largest such assemblage ever found in Europe, more than triple the previous record (308.5kg at Durrenentzen). Shape alone would date bars like these to the Early Iron Age (8th–5th c. BC), the working assumption for this bar type until now. The authors dated the metal itself instead: carbon gets trapped in the cementite of steel during smelting, so it can be radiocarbon-dated directly, no organic material required. Three bars, two independent AMS measurements apiece, all converging on the Late Iron Age (4th–1st c. BC) — centuries later than the typology implied, the first time this variant has been dated rather than assumed from its outline. They also argue shipwreck over ritual deposit: Late Iron Age river offerings are rare in this culture and the ones that exist mix object types, while Deinham is a uniform cargo of raw semi-products — the shape of a lost load, not an offering. The close is a value argument: a tonne of iron is roughly 500 swords' worth or enough nails for half the wooden defensive wall at the nearby oppidum of Manching, and against a list of what could plausibly move back upstream in exchange (not grain, not salt — too bulky to carry against the current), the authors land on gold or silver coin, making this the archaeological equivalent of a large monetary hoard from a culture just starting to use coinage."

Its own 2023 board presentation (M2023-47) flagged \"unknown ROW needs in early design\" as a live risk at the time — this project is still at 1-2% design, per that same presentation, which is likely why a number this granular doesn't exist yet as a public document."

Limit: EVT-3D and EVT-2C are close enough on this count that it doesn't cleanly support \"3D is worse because of the stadium\" — the segment runs the length of downtown, not just the four blocks in question, so this doesn't resolve the exposure question either way. Still holding for an actual acreage/footprint number if one ever gets published — this isn't it."
