A rig-managed machine recorded nothing about its own provenance. The entire
durable output of a bootstrap run was one line in /etc/rig/role, and that line
says what the box IS, never what built it. VERSION was read in exactly one
place (bin/rig:9, for --version) and reports the currently INSTALLED tree, not
the one that ran; there was no timestamp anywhere in the codebase.
bootstrap now stamps a second file beside the marker: schema=1, a birth pair
(bootstrapped_by/_at, pinned forever) and a latest pair (converged_by/_at).
key=value, one per line, 0644 — the one file that must stay readable on the
most broken machine in the fleet, where there is no YAML parser and no jq.
`rig manifest [<key>]` reads it back.
Only DECIDED facts go in, which is what keeps bootstrap.sh:3's convergence
contract intact: bootstrapped_* is first-write-wins, and converged_* updates
only when the version actually differs — it is the time the converging version
last changed, not the time of the last run. The renderer is pure, so a re-run
by the same rig is byte-identical no matter where the clock is, and the
cmp-guard stays silent. OBSERVED facts (cores, RAM, disk, kernel) stay out:
they go stale on their own and belong to `rig platform` (#64).
/etc/rig/role is untouched.
