1//! Process CRD — the K8s-as-Unix-processes wire format.
2//!
3//! A `Process` is one element of the tatara convergence lattice.
4//! Clusters, HelmReleases, migrations, tests — all are Processes.
5//! The reconciliation loop *is* Unix: fork → exec → wait → exit → reap.

167/// Substrate-primitive builder for a Process-owned resource's
168/// **`metadata.ownerReferences` array** — the empty-uid-gated,
169/// single-entry `Vec<Value>` every emit site that lacks a fully
170/// materialized [`crate::prelude::Process`] (i.e. every site that
171/// works from a bare `(name, uid)` pair rather than routing through
172/// [`ssapply::build_owner_reference`](../tatara_reconciler/ssapply/fn.build_owner_reference.html)'s
173/// anyhow-guarded unwrap) hand-composed by wrapping
174/// [`owner_reference_json`] in a `Vec::new()` + `is_empty` gate on
175/// the `uid` slot.
176///
177/// The `uid.is_empty()` gate encodes the invariant every caller
178/// already enforced: a Process pre-metadata (fixtured in tests, or
179/// caught mid-Forking before the API server has stamped a `uid`) has
180/// no admissible owner reference to point at, so the emit site
181/// stamps `metadata.ownerReferences: []` rather than an
182/// owner-referenceless resource pointing at a placeholder uid the K8s
183/// GC would silently ignore. Post-lift the gate lives at ONE
184/// primitive so a regression that inlined an owner reference for
185/// an empty uid — which the API server accepts and quietly detaches
186/// from cascade-delete — surfaces at THIS primitive's pin rather
187/// than as an operator-visible ownerless resource after apply.
188///
189/// Pre-lift the 3-line `let mut owner_refs = vec![]; if
190/// !uid.is_empty() { owner_refs.push(owner_reference_json(name,
191/// uid)); }` incantation was hand-authored at TWO sites past the
192/// ★★ PRIME-DIRECTIVE ≥ 2 duplication threshold in
193/// `tatara-reconciler`, each restating the same gated composition:
194/// * `edges::build_owner_refs` — the shared owner-refs builder both
195///   `IngressEdge` + `DnsEndpointEdge` route through, sourcing
196///   `(process_name, process_uid)` from the [`crate::edges::EdgeContext`].
197/// * `render::one_export_job` — the export Job's owner-refs seed,
198///   sourcing `(name, uid)` from the [`crate::prelude::Process`]
199///   `render_export_jobs` threaded in.
200///
201/// Post-lift both callsites read `owner_references_json(name, uid)`.
202/// A future addition — e.g. a second owner-reference slot naming a
203/// controlling ProcessTable entry, a policy that stamps a stale-uid
204/// warning annotation before returning empty, or a normalization
205/// that strips a cluster-prefix off the uid — lands at ONE
206/// substrate function here and every emit site inherits the upgrade
207/// mechanically. The [`ssapply::build_owner_reference`] path (which
208/// works from a materialized [`crate::prelude::Process`] and errors
209/// on absent `metadata.uid`) is a peer, not a lift candidate: its
210/// contract is "the K8s API server assigned a uid, so refuse to
211/// SSA-apply resources whose owner cannot be materialized", while
212/// this primitive's contract is "the caller has an optional-uid
213/// posture; emit `[]` when the uid is absent". The two shapes
214/// partition the input space at the "is the enclosing scope
215/// obligated to produce a materialized Process reference" axis.
216///
217/// The 2-arg `(&str, &str)` signature accepts both the
218/// `EdgeContext`-sourced `(&str, &str)` slice shape and the
219/// `render_export_jobs`-owned `(name: &str, uid: &str)` local shape
220/// without widening — matches every current callsite.
