- README status, the ROADMAP P1 row with the measured site and accessor counts, and the
ARCHITECTURE correction from 293 to the 277 arrow sites the tree actually has
- MEASUREMENTS gains the P1 scale table, the two classes of finding the verify lane
produced (nine missing fill rows, three fields a backend moves inside its own verb) with
the push-on-mutation decision and its three hooks, and the acceptance numbers
- the sentence read as if 836 of the 92 immediate calls were RecordError; 836 is RecordError's share of all 926 calls, and most of the 92 immediate ones are RecordError
- README.md: what MGPipe is, the one-paragraph architecture, the P0 status line, the file and code map, and the commit range where the design competition and the three adversarial review rounds live
- ARCHITECTURE.md: the design as decided, one reason per decision - handles and generations, the 71-call catalogue by class with flags and cap bits, record and payload conventions, the tracker, texture subdata and dirty ownership, shader state and the P0.5 header extraction, the reverse channel, the backend strangler, the server side and the index host mirror, the transport as landed in MG_Remote, the persistent-map tiers as measured, roundtrips, present and threads, process and platform delivery, build shapes and purity gates, the five-part verification gate, and the knob tables marked landed versus planned
- ROADMAP.md: P0..P13 as one table of what lands, the gate and the dependency, the two tracks and milestones, the day-43 GO/NO-GO checklist with both exits, the re-baseline checkpoints, and the questions still open after P0
- MEASUREMENTS.md: spike A on both devices, the spike B tier matrix, the four-trace boundary-counter baselines on both backends, the desktop and corpus facts, and the harness traps with the exact commands
- every file:line kept is verified at 458ccde1 and the citation lint is clean; everything else cites a symbol plus a file
- dropped on purpose: the v1/v2 revision archaeology, rejected alternatives, per-subsystem day estimates, the Feat/CS-Delta-IPC reuse audit and the reviewer back-and-forth
