fix(ci): add IMPORT_HOST_DIR stub to compose-idempotency env file

Docker Compose interpolates all variables in the full file even when only a subset of services is requested. The backend service uses IMPORT_HOST_DIR with :? (hard-required), causing the idempotency job to abort before any container starts. A dummy path satisfies the parser; the backend service is never started in this job so the path need not exist.

-An observability stack is available via `docker-compose.observability.yml`. Configuration lives under `infra/observability/`. Start it after the main stack is up (which creates `archiv-net`):

-docker compose up -d                                    # creates archiv-net

-| `obs-node-exporter` | `prom/node-exporter:v1.9.0` | Host-level CPU / memory / disk / network metrics |
-| `obs-cadvisor` | `gcr.io/cadvisor/cadvisor:v0.52.1` | Per-container resource metrics |
-| `obs-loki` | `grafana/loki:3.4.2` | Log aggregation — receives log streams from Promtail. Port 3100 is `expose`-only (not host-bound). |
-| `obs-promtail` | `grafana/promtail:3.4.2` | Log shipping agent — reads all Docker container logs via the Docker socket and forwards them to Loki with `container_name`, `compose_service`, and `compose_project` labels |
-| `obs-tempo` | `grafana/tempo:2.7.2` | Distributed trace storage — OTLP gRPC receiver on port 4317, OTLP HTTP on port 4318 (both `archiv-net`-internal). Grafana queries traces on port 3200 (`obs-net`-internal). All ports are `expose`-only (not host-bound). |

-
-# List labels
-docker exec obs-loki wget -qO- 'http://localhost:3100/loki/api/v1/labels'
-
-# Query logs by service (stable across dev and prod environments)
-docker exec obs-loki wget -qO- \
-  'http://localhost:3100/loki/api/v1/query_range?query=%7Bcompose_service%3D%22backend%22%7D&limit=5'
-```
-
-**Prefer `compose_service` over `container_name` in LogQL queries** — `container_name` differs between dev (`archive-backend`) and prod (`archiv-production-backend-1`), while `compose_service` is stable (`backend`, `db`, `minio`, etc.).
-
-Prometheus port `9090` is bound to `127.0.0.1:${PORT_PROMETHEUS:-9090}` on the host. No other observability ports are host-bound. Full wiring and Grafana dashboards are tracked in issue #581.
+Phase 7 of the Production v1 milestone adds Prometheus + Loki + Grafana. No monitoring infrastructure is in place yet.

-# ADR 014 — Pin actions/upload-artifact to v3 (Gitea act_runner v4 protocol incompatibility)
-
-**Status:** Accepted  
-**Date:** 2026-05-14  
-**Issues:** [#557 — re-regression](https://git.raddatz.cloud/marcel/familienarchiv/issues/557) · [#14 — original incident](https://git.raddatz.cloud/marcel/familienarchiv/issues/14)
-
---
-
-## Context
-
-`actions/upload-artifact` is available in two incompatible major versions. The v4 client
-uploads via a GitHub-specific artifact API that is **not implemented** in Gitea's
-`act_runner` (the self-hosted CI substrate established by ADR-011). When a workflow step
-uses `actions/upload-artifact@v4` on this runner, `act_runner` returns a non-zero exit
-code from the v4 client even when all tests pass, producing:
-
-> green test suite — red job status — no artifact uploaded
-
-The failure lands in the upload step, _after_ the test output, making it hard to diagnose
-from the build log.
-
-### Incident history
-
-| Date | Commit | Event |
-|---|---|---|
-| 2026-03-19 | `9f3f022e` | Original downgrade: `upload-artifact@v4 → v3` |
-| 2026-03-19 | `4142c7cd` | Rationale committed; closes #14 |
-| 2026-05-05 | `410b91e2` | Re-regression: upgraded back to v4 without referencing #14 |
-| 2026-05-14 | this PR | Second downgrade + ADR + grep guard |
-
-The root cause of the re-regression was institutional-memory failure: the original
-rationale was captured only in a commit body, invisible at the point of change (the
-`uses:` line). This ADR, the inline comments, and the grep guard are the three
-defence layers that replace that missing breadcrumb.
-
---
-
-## Decision
-
-**Pin all `actions/upload-artifact` and `actions/download-artifact` call sites to `@v3`.**
-
-Both action families share the same v4 protocol incompatibility with `act_runner`.
-Pinning to the major tag (`@v3`) keeps us on the latest v3 patch without Renovate noise.
-
-Three call sites are pinned:
- `.gitea/workflows/ci.yml` — "Upload coverage reports" step
- `.gitea/workflows/ci.yml` — "Upload screenshots" step
- `.gitea/workflows/coverage-flake-probe.yml` — "Upload coverage log on failure" step
-
-Each pinned `uses:` line carries a load-bearing inline comment:
-
-```yaml
-# Gitea Actions (act_runner) does not implement upload-artifact v4 protocol — pinned per ADR-014. Do NOT upgrade. See #557.
- uses: actions/upload-artifact@v3
-```
-
-A CI grep guard enforces the constraint automatically (see below).
-
---
-
-## Consequences
-
-### Enforcement layers (defence in depth)
-
-1. **Inline comments** on every `uses:` line — visible at the point of change.
-2. **CI grep guard** in `.gitea/workflows/ci.yml` ("Assert no (upload|download)-artifact
-   past v3") — fails the build if a future commit re-introduces `@v4` or higher on any
-   workflow file. Anchored to YAML `uses:` lines to avoid false positives on embedded
-   shell strings. Includes a self-test that proves the regex catches v4+ before scanning
-   the repo.
-3. **This ADR** — canonical rationale; cross-referenced by comments and guard message.
-
-### How to spot the symptom
-
- Test suite output shows green (vitest, surefire, pytest all exit 0)
- CI job status shows red
- Artifacts section of the run is empty
- Build log shows a non-zero exit from the `Upload …` step immediately after green tests
-
-### `@v3` maintenance-mode status
-
-GitHub placed `actions/upload-artifact@v3` in maintenance mode (no new features) but it
-has not been removed and carries no known unpatched CVE as of this writing. If GitHub
-publishes a v3-specific security advisory, that is an additional trigger to re-evaluate
-(see upgrade conditions below).
-
-### When to remove this pin
-
-Re-evaluate pinning **when either condition is met:**
-
-1. `gitea/act_runner` ships a release with v4 artifact protocol support. Track upstream:
-   <https://gitea.com/gitea/act_runner>
-2. `actions/upload-artifact@v3` acquires an unpatched CVE that cannot be mitigated
-   at the runner level.
-
-When upgrading: remove the grep guard step, update all three `uses:` lines, remove the
-inline comments, and update this ADR's status to Superseded.
-
---
-
-## Alternatives
-
-### SHA pinning (`uses: actions/upload-artifact@<sha>`)
-
-More secure against action repository compromise, but adds Renovate update friction
-and is disproportionate for a self-hosted, single-tenant Gitea instance with one
-trusted contributor (ADR-011). Rejected.
-
-### Minor/patch pinning (`@v3.4.0`)
-
-Avoids Renovate PRs but freezes us on a specific patch. The v3 major track is in
-maintenance mode — minor pinning has no benefit and would require manual updates
-for any v3 security patches. Rejected.
-
-### Renovate `packageRules` bypass
-
-Would prevent automated PRs from proposing v4. Not needed while Renovate is not
-configured for this repository. Revisit if Renovate is introduced.
-
-### Migrating the runner to a v4-compatible Gitea release
-
-Out of scope for this issue. A separate decision; tracked in #557's non-goals.
