# ops-warden architecture decision records
|
|
|
|
This directory holds the rules **ops-warden owns** — the decisions this repo made,
|
|
is bound by, and is responsible for changing.
|
|
|
|
## Why these exist as ADRs rather than wiki prose
|
|
|
|
Until 2026-08-18 every rule in this list lived in wiki prose, a workplan, or a
|
|
comment at the top of `registry/routing/catalog.yaml`. All of them were being
|
|
followed. None of them was *addressable*: a reader outside ops-warden could not
|
|
cite one, could not tell whether it was current, and could not tell whether it
|
|
was ours to change or someone else's that we merely obey.
|
|
|
|
That distinction is the point of this directory. It matters in both directions:
|
|
|
|
- **A rule we own, mistaken for inherited canon, never gets fixed.** We wait for
|
|
an owner who does not exist.
|
|
- **Inherited canon, mistaken for ours, gets quietly bent.** We change something
|
|
we had no authority over, and the drift is invisible until it breaks a repo
|
|
that trusted the canonical version.
|
|
|
|
## Owned versus inherited
|
|
|
|
Every ADR here carries `owner:` in its frontmatter. It is the load-bearing field.
|
|
|
|
| `owner:` | Meaning | How it changes |
|
|
| --- | --- | --- |
|
|
| `ops-warden` | **Ours.** We decided it, we are bound by it, and we may change it | A new ADR that supersedes this one. Never an edit-in-place that rewrites a decision |
|
|
| anything else | **Inherited.** We follow it; we do not own it | Through that owner's process. We may dispute it — we may not amend it |
|
|
|
|
Everything currently in this directory is `owner: ops-warden`. Rules we follow but
|
|
do not own — NetKingdom canon, the IAM profile, the credential-management standard
|
|
— are *not* copied here. They are cited. Copying inherited canon into our own ADR
|
|
directory would recreate exactly the second-source-of-truth failure that
|
|
`ADR-0001` exists to prevent.
|
|
|
|
## Superseding one of these
|
|
|
|
A decision here changed the behaviour of other repos, so retracting it silently is
|
|
not available. Write a new ADR, set the old one's `status: superseded` and
|
|
`successor:`, and leave it in place. Superseded is a lifecycle state; deletion is
|
|
not. `policy-nexus` publishes the history, and a reader asking "what did this say
|
|
when we made that decision" must be able to find out.
|
|
|
|
## Relationship to `.claude/rules/`
|
|
|
|
`.claude/rules/*.md` are **agent-facing operational instructions**. They tell an
|
|
agent what to do in a session. They are derived from these ADRs and should cite
|
|
them rather than restate the reasoning. If the two disagree, the ADR is right and
|
|
the rule file is a defect.
|
|
|
|
## Publication
|
|
|
|
These are publishable through `policy-nexus` at `policy.coulomb.social`, which
|
|
requires `title`, `status` and `owner` on every document and renders Owner as a
|
|
column in its index. The ownership knowledge therefore survives publication
|
|
rather than being a local convention that evaporates at the repo boundary.
|
|
|
|
`policy-nexus` publishes; it never writes back. The file in this directory is the
|
|
source of truth. If the site and this directory disagree, this directory is right
|
|
and the publication is a defect.
|
|
|
|
| ADR | Rule | Binds |
|
|
| --- | --- | --- |
|
|
| `ADR-0001` | The routing catalog is a pointer layer, never a second copy of an owner's procedure | ops-warden, and every repo contributing a catalog entry |
|
|
| `ADR-0002` | ops-warden is a transparent conduit, never a secret broker | ops-warden |
|
|
| `ADR-0003` | Cover gaps, but never silently own them | ops-warden |
|
|
| `ADR-0004` | High-risk lanes refuse raw value streaming to agent sessions | ops-warden, and any agent runtime calling `warden access` |
|
|
| `ADR-0005` | Implement one lane narrowly, route everything else | ops-warden |
|
|
| `ADR-0006` | Enforcement is zone-scoped, never a global flag (**superseded by ADR-0009**) | ops-warden |
|
|
| `ADR-0007` | Build-stage permissiveness stops at credential disclosure | ops-warden |
|
|
| `ADR-0008` | A lane's risk grade covers every field its path discloses | ops-warden |
|
|
| `ADR-0009` | Adopt security-zones v0.1; compile explicit membership and select PEP failure mode per zone | ops-warden |
