rtk lives at ~/.cargo/bin but the hand-managed .bashrc lost the cargo line: command -v failed in hook AND tool shell, so the hook no-op'd with a stderr warn on every Bash call — input compression silently OFF. - Resolve RTK_BIN by probing known install dirs (LRN-036 class). - Substitute the ABSOLUTE path at the rewrite head: a bare 'rtk …' exits 127 in the tool shell, whose PATH the hook cannot fix (proven). - Compound rewrites carrying further bare rtk segments pass through unrewritten: quoted text (commit messages) makes a global substitution unsafe — lose compression, never emit a command that 127s (proven: a commit chain 127'd mid-flow). - detect_rtk probes the same dirs so the banner reports capability. - Re-pinned .rtk-hook.sha256: the rtk BINARY verifies the hook against it at execution time and refuses a modified hook — the pin is live machinery, not a vestige; coupling documented in the header.
