Jochen asked whether the order made sense. It did not -- it followed when
things happened to be decided, which after consolidation is fictional anyway
since record 5 alone folds decisions taken across a week.
Concretely wrong before: the domain statement sat at 8, after five engineering
rules; the constitution was scattered across 5, 12 and 17; the tiers landed at
15, 16, 21 and 22 with process records in between.
Now it walks: what the mesh is (1-3), its tiers from the bottom up (4-8), what
runs on them and how it gets there (9-10), how it is built (11-16), how it is
checked (17-18), how we work (19-23).
Two things made this safe rather than free. It is a permutation, not a
compaction, so the renames go through temporary names -- otherwise two files
want one slot and one is lost. And the reference rewrite is a single
simultaneous pass, because almost every number moved into a slot another number
was vacating; replacing one at a time would have cascaded and pointed things at
the wrong record while still resolving.
Verified: 284 [ADR NNNN](path) links across the repository, all with matching
text and target.
The ordering principle is now stated in 19 rather than left implicit -- the
repository already said "the numbering is the flow" about its folders, and
there was no reason for the records to be the exception.
The consolidation left a sparse sequence -- 1, 4, 6, 7, 9, 10, 12, 15, 16, 18,
19, 25, 34, 35, 36, 37, 40, 42, 44, 45, 48, 49, 58 -- where the gaps were only
the archaeology of what used to be there.
Renumbered contiguously. Renames run in ascending order, so every target number
is already free and no two files ever collide.
The reference rewrite is one simultaneous pass rather than a sequence of
replacements. Numbers moved into slots other numbers were vacating -- the node
host went 37 to 16 while the lab went 16 to 9 -- so replacing one at a time
would have cascaded and silently pointed things at the wrong record.
Seven plain-text references survived the merges as prose rather than links,
naming records that no longer existed: the enrolment token, the link boundary,
what a declaration is, reachability, the repository structure. Each mapped to
the consolidated record that now holds it.
Verified rather than assumed: every [ADR NNNN](path) link now has matching text
and target, checked across the whole repository, and the checker passes.
Frontmatter `consolidates:` lists dropped -- they named records that are gone,
and each consolidated record already says in prose what it absorbed.
The domain-grouping premise is testable, so it was tested before drawing a
list. Co-change across the full history of the module catalogue, current
modules only, platform namespace excluded.
Nine commits in ten touch exactly one module, and 50 of 89 modules have
never been edited alongside anything. Two clusters exist above that floor.
Reachability holds up: proxy, resolver, firewall and VPN genuinely move
together under one intent, three times in recent history. That is the shape
ADR 0017 describes and the only place the measurement finds it.
The provider cluster does not, and this is the finding worth having. Every
multi-provider commit is a cross-cutting manifest change applied N times —
feature detection, hook conventions, volume binds, network scoping. None is
a change to what a database is. Merging them would not have prevented one
of those commits, and the history already shows the fix that worked:
verify by shape in the SDK rather than copying a script into every module.
Move the concern into the machinery, do not merge the modules carrying it.
ADR 0017 keeps its principle and gains a pointer to this narrowing.
