From fcd9f23ee12738f497fadbab37b2036e5b09f033 Mon Sep 17 00:00:00 2001 From: dtoro Date: Wed, 8 Jul 2026 11:16:04 +0200 Subject: [PATCH] transition precondition enforcement + thin-client context poller MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Plan #3 at 100%. Last three items resolved: 1. Transition precondition enforcement (Phase 5): - no-inbound-edges: blocks destroy when relationships exist - backups-verified, secrets-revoked, ingress-dns-removed: checks attrs - age-key-enrolled-if-needed, mesh-joined-if-needed: workstation checks - health-check-answering: verifies entity_status health - doc-page-complete: requires at least one linked document - Soft preconditions (inventory-entry, cancelled-note, etc.): operator confirmed via transition request itself - Parses {requires: [check-name]} from lifecycle_defs.transitions JSONB 2. bootstrap.sh: already thin-client (fetches only agent files, no git clone, calls POST /clients/enroll, embeds context poller) 3. tools/context-poller.sh: standalone version — polls GET /clients/{slug}/context, applies file/tool/sops deltas, re-runs changed setup scripts --- internal/httpapi/impl.go | 116 ++++++++++++++++-- plans/2026-07-07-client-lifecycle-in-go.md | 2 +- plans/2026-07-08-plan-implementation-audit.md | 33 +++-- tools/context-poller.sh | 73 +++++++++++ 4 files changed, 203 insertions(+), 21 deletions(-) create mode 100644 tools/context-poller.sh diff --git a/internal/httpapi/impl.go b/internal/httpapi/impl.go index ce7c6da..e0ab0bb 100644 --- a/internal/httpapi/impl.go +++ b/internal/httpapi/impl.go @@ -974,14 +974,10 @@ func (s *Server) PatchEntity(ctx context.Context, req gen.PatchEntityRequestObje if err != nil { if err == pgx.ErrNoRows { // No lifecycle defined — any state is allowed. - _ = lc } else { return nil, err } } else { - // Transitions are stored as {from: {to: {requires: [...]}}} - // (see seeds/ontology.yaml).
