+# Intent
+
+Vergabe Teilnahme is the primary customer service and UI product for the first
+HelixForge factory delivery lane, as selected by Bernd Worsch on 2026-09-08.
+It helps a company's team manage tender participation: deadlines, lots,
+requirements, decisions, evidence, submission and retrospective learning.
+
+The existing Django product remains the implementation home. The first customer
+offering should preserve its single-company boundary, with an isolated deployment
+per admitted company until a separately designed tenancy model is accepted.
+Customer availability follows verified access, persistence, restore, release and
+support arrangements; this intent does not claim those gates are complete.
+
+The product requirements and domain workflows remain in
+[wiki/ProductRequirementsDocument.md](wiki/ProductRequirementsDocument.md).
+Factory integration is coordinated by `prj-helixforge-factory/HFACT-WP-0001`.
+Reuse-surface supplies internal capability discovery before new implementation;
+customer users interact with the tender UI.

+# Delivery checks
+
+Before implementing a workplan, use the hosted reuse registry:
+
+```sh
+make plan-check WORKPLAN=workplans/VERGABE-WP-0018-customer-factory-delivery.md
+```
+
+Install a reuse-surface revision containing REUSE-WP-0022. The initially tested
+provider revision is recorded in
+[evidence/2026-09-08-hosted-plan-check.json](evidence/2026-09-08-hosted-plan-check.json).
+`REUSE_SURFACE_BIN` can select an explicit installed executable;
+`REUSE_SURFACE_URL` defaults to `https://reuse.coulomb.social`.
+
+This reads current hosted capabilities with `--no-llm`. It sends no tender intent
+or mutation token to the registry. A failed/stale/partial source exits nonzero
+without a recommendation. Preserve JSON output with the source revision in the
+workplan evidence; a lexical `new` result still requires review of existing
+capability owners. For this delivery we reuse reuse-surface, Railiance CI tooling
+and the existing Railiance Apps deployment rather than establish new equivalents.
+
+## Application and release gate
+
+```sh
+make test-image
+```
+
+The `application-tests` Docker target installs the locked Python dependencies,
+builds Vite/Tailwind assets, collects static files, runs the complete Django
+application suite against disposable SQLite data, and checks migration drift.
+It includes the existing tender → lot → approval and submission workflow tests.
+The target carries no production database connection or release credential.
+SQLite proves this application acceptance suite; target PostgreSQL and live
+storage/recovery behavior remain release admission checks.
+
+The Forgejo application workflow checks proposed changes. The image workflow
+runs the same target on the same archive revision **before** registry login and
+publication. Test dependencies and test settings are isolated from the runtime
+image. The existing optional BuildKit package secrets remain supported, but the
+current issue-core package is anonymously readable; no new secret is required.
+
+The corrected Dockerfile consumes application templates under
+`vergabe_teilnahme/templates/`. A fresh archive does not contain a root
+`templates/` directory; attempting to copy it previously broke clean builds.
+
+## Customer release acceptance
+
+VERGABE-WP-0018-T03 owns the first admitted Railiance customer pilot: exact image
+digest and chart revision, tenant/host and login binding, database and media
+ownership, backup/restore and rollback, UI smoke and named operating owner.
+Existing production tender data is never disposable test data. A passing source
+build does not establish customer availability or the governed factory worker.

+# Customer product delivery
+
+## Core Idea
+
+Make the existing tender-participation UI a repeatably tested customer product.
+Use hosted capability discovery for planning, exercise the existing useful
+tender/lot/approval workflow, and prevent image publication when application
+acceptance fails. Preserve single-company scope until a separate tenancy design.
+
+## Establish product authority and reuse discovery
+
+```task
+id: VERGABE-WP-0018-T01
+status: done
+priority: high
+assignee: the-custodian
+```
+
+Update product entry points and classification to reflect the user's explicit
+customer-product selection. Add a reproducible `make plan-check WORKPLAN=...`
+consumer of REUSE-WP-0022, with no model call or mutation credential. Pin and
+record the tested provider revision and hosted snapshot receipt. A low lexical
+score requires owner review; it does not authorize a duplicate capability.
+
+## Gate releases with useful application acceptance
+
+```task
+id: VERGABE-WP-0018-T02
+status: progress
+priority: high
+assignee: the-custodian
+```
+
+Run existing application tests against disposable data, including tender create,
+lot create, approval and submission. Add a reproducible container acceptance
+target with locked dependencies, built assets and migration drift checks. Run it
+on proposed changes and before the existing image publication step. Record
+immutable reviewed source, CI outcome and resulting artifact separately.
+
+## Accept the first Railiance customer pilot release
+
+```task
+id: VERGABE-WP-0018-T03
+status: wait
+priority: high
+assignee: the-custodian
+depends_on: [VERGABE-WP-0018-T02, HFACT-WP-0001-T05]
+blocking_reason: "Await tested/reviewed image and exact Railiance tenant, deployment, database, storage, access and recovery owner acceptance."
+```
+
+Coordinator: the-custodian; product acceptance: Bernd Worsch; deployment owner:
+railiance-apps and admitted Railiance placement owner. Prepare exact chart/image,
+host, tenant, credential binding, existing-data disposition, backup/restore,
+rollback and UI acceptance evidence before release. Use an isolated internal
+pilot first; existing `vergabe_db` is not test data and must not be relocated or
+overwritten implicitly. No customer-ready claim until admitted release passes.
+Return the release and consumer evidence to HFACT-WP-0001-T06/T07.
+
+## Source acceptance — 2026-09-08
+
+- Full application suite: 82 passed locally with SQLite and again with a
+  disposable PostgreSQL 16 container; no production data used.
+- Clean container application target: 82 passed, Vite/Tailwind built, 139 static
+  files collected, no migration drift. One pre-existing naive-datetime warning.
+- Runtime image built successfully; loopback health HTTP 200 as UID 999;
+  pytest absent from runtime. See `docs/evidence/2026-09-08-runtime-smoke.json`.
+- Clean-build defect fixed: root `templates/` does not exist in published source;
+  application templates already reside under `vergabe_teilnahme/templates/`.
+- Hosted discovery consumed from reuse-surface implementation `2621cf2`;
+  65-capability provenance and review disposition are in
+  `docs/evidence/2026-09-08-hosted-plan-check.json`.
+
+T02 remains in progress until the published exact revision has its CI return.
+T03 retains the concrete deployment/data/access/recovery gates. Attended Codex
+source work is not a natural governed worker claim/heartbeat/close trace.
