Ran the rehearsal read-only against a live production instance. It
completed, and two preflight checks were wrong in ways a test instance
could not have shown.
1. Store-backend detection missed the config entirely. A config generated
by `stalwart --init` declares `type = "rocksdb"` inside a
`[store.rocksdb]` section, which is what every test fixture here used.
The production config has no section headers at all and declares
`store.rocksdb.type = "rocksdb"` flat. Detection only matched a bare
`type` key, so it reported "no known store backend type found in config"
and left topology.store_backend empty.
That mattered more than a warning suggests: backup.Run treated an
unrecognized backend as a *skip*, so a real run would have continued
with no filesystem or database backup at all - the single artifact that
phase exists to produce, quietly absent. Flat dotted keys are now
detected, and an unrecognized backend is a hard failure rather than a
skip.
2. The cluster warning didn't say where it matched. It fires on any
occurrence of "cluster" anywhere in the config, which is the correct
bias - a missed cluster corrupts a shared store - but on the production
config the only match was inside the value of an unrelated setting,
leaving a whole config to search to establish that. It now names the
location and distinguishes a match in the setting name from one in its
value.
Both verified against the real config: store-backend now reports
"rocksdb (store.rocksdb)", and the cluster warning names the setting,
making a false positive dismissible at a glance.
No production data is in this commit: the fixtures use example.com and the
flat-key shape only. Coverage numbers from that run matched the earlier
scrubbed-corpus measurement exactly.
GPLv3's "How to Apply These Terms" asks for a notice in each source file;
this is the modern two-line SPDX form of it rather than the full paragraph.
82 files, including tests.
The blank line after the header is load-bearing. In Go a comment block
immediately preceding `package X` becomes the package doc comment, so
without the separator the SPDX lines would be absorbed into the doc for the
eleven packages whose doc.go (or main.go) opens with one, and `go doc` would
print them. Verified it doesn't.
