State facts from the transcript only — no speculation, no preamble, no closing remarks.\nDo NOT compile a roster of peer agents: name another agent only where the transcript shows a direct exchange with it. Machine/host/node names (window titles like `agent @ HOST`, CI runner boxes, `spt endpoint list` node headers) are computers an agent runs ON, not agents — never list a host as a peer or an agent.\nSlice the delta so spt routes each part to the right durable tier: put everything specific to THIS project (its task, files, and decisions) inside <project-context>…</project-context>, and any cross-project, role, or standing-identity context inside <live-context>…</live-context>. Untagged text defaults to the live tier, so tag project-specific detail to keep it out of the durable identity.

WHY THIS EXISTS: a full volume reds as a LINKER defect that names no disk —\\n//! `LINK: fatal error LNK1318: Unexpected PDB error` (the parenthesised code\\n//! varies), beside `LNK4209: debugging information corrupt`, and once as a\\n//! `traceable-reqs check` PANIC with `os error 112`. Nothing in any of those\\n//! says \\\"disk\\\". Two agents spent hours on a mechanism for one of them and\\n//! neither read free space; the falsifier was one command away throughout.\\n//!\\n//! WHY IT IS A VERB AND NOT A LINE IN A SCRIPT: the entry's remedy asks for the\\n//! reading in \\\"the rig/gate preflight path\\\", and there is no such path in the\\n//! tree to amend — the gate legs that hit this ran as PLAIN SCRIPTS, authored\\n//! per run, which is the entry's own second face.

ITS OUTPUT SHAPE IS GOLDEN'S, DELIBERATELY. The golden runner's preflight\\n//! step prints `disk preflight: drive=<d> free_bytes=<n> floor_bytes=<n>` and\\n//! fails with `RESOURCE=disk drive=<d> free_bytes=<n> floor_bytes=<n>`; this\\n//! verb prints the same keys so one grep reads local rig logs and CI logs\\n//! alike.

WHY THIS EXISTS: a full volume reds as a LINKER defect that names no disk —\\n//! `LINK: fatal error LNK1318: Unexpected PDB error` (the parenthesised code\\n//! varies), beside `LNK4209: debugging information corrupt`, and once as a\\n//! `traceable-reqs check` PANIC with `os error 112`.

WHY IT IS A VERB AND NOT A LINE IN A SCRIPT: the entry's remedy asks for the\\n//! reading in \\\"the rig/gate preflight path\\\", and there is no such path in the\\n//! tree to amend — the gate legs that hit this ran as PLAIN SCRIPTS, authored\\n//! per run, which is the entry's own second face.

PR #180 open at https://github.com/BigscreenVR/spt-bs-core/pull/180.\n\n### Defect found and fixed\nLive arms of the verification run (`verify59.sh`) surfaced a real bug: `drive_of()` used `path.canonicalize()` which on Windows returns the verbatim prefix form `\\\\?\\C:\\`, breaking grep parity with the golden CI runner's expected `drive=C:\\` in the `disk preflight: drive=<d> free_bytes=<n> floor_bytes=<n>` log line (and the `RESOURCE=disk ...` failure line). This defeated the entire purpose of the shared output shape (one grep reads both local rig logs and CI logs).\n\n### Fix applied\nRewrote `drive_of()` in `diskfloor.rs` to match on `std::path::Prefix::Disk`/`Prefix::VerbatimDisk` and reconstruct a bare `X:\\` drive letter (uppercased), falling back to the raw prefix spelling only for non-disk prefixes (UNC/device paths), and keeping `/` for POSIX root. Added doc comment explaining the verbatim-prefix stripping is deliberate, and referenced that the pool guard already does this same normalization for junction targets.\n\n### Test added\nNew unit test `the_drive_is_spelled_the_way_the_golden_runner_spells_it` in `diskfloor.rs` tests module: asserts no `\\\\?\\` prefix leaks, and on Windows the drive is exactly 3 chars ending in `:\\`; on non-Windows asserts `/`. Both edits applied successfully (verified via Edit tool results, no re-read needed).\n\n### Status / next steps\nJust launched `bash verify59.sh` in background (task ID `b2bywrkcu`, output at `C:\\Users\\decid\\AppData\\Local\\Temp\\claude\\...\\tasks\\b2bywrkcu.output`) to rerun all six verification legs against the fix. Session ended before checking the output — next step is to read that background task's output to confirm the fix passes, then likely run clippy/traceable-reqs checks and push/update PR #180.\n</project-context>\n\n<live-context>\nAgent \"todlando\" operating in repo `spt-core` on host HFENDULEAM, git branch `feat/ir57-pick-fidelity`.
