Bump opencode 1.15.4 -> 1.15.6 + cut v1.15.6

Two upstream patch releases since v1.15.4b. Plus this release picks up
two workflow improvements that landed on main between v1.15.4b and
now (b6e4d89 pycache/DS_Store filter in base-decide, 90e5a1f doc-drift
sweep clause in AGENTS.md). No image-content changes beyond the
version bump; cache hit expected on base-35ee5fe7861a since neither
Dockerfile.base nor rootfs/ have changed.

The with-pi and omos-with-pi variants will also implicitly bump pi
0.75.3 -> 0.75.4 because PI_VERSION=latest resolves at build time.
The omos-with-pi smoke threshold (3700 MB after the v1.15.4b bump)
should accommodate two opencode patch versions plus one pi patch
without recurrence of the trip; a future bump-bump pattern would
push it again.

First release on the new CI path that exercises:
- pinned crane install (T14, v1.15.3) - only fires on real base rebuild,
  cache-hit on base means it stays unexercised this run too
- skip promote-base-latest on cache-hit (T15, v1.15.4) - active
- update-description always-and-success-of-base wrap (v1.15.4b) -
  active, will run since base variant publishes

   Release-day checklist: README → (regenerate DOCKER_HUB.md only if HUB_TEMPLATE changed) → promote CHANGELOG Unreleased → grep AGENTS.md for stale counts → commit → tag → push tag.
+
+  **Between releases the same coupling applies.** Doc drift is not just a release-day concern — a workflow tweak, entrypoint change, or `generate-config.py` refactor can leave any of these four files lying. Before committing a non-release change, grep the docs for references to what you touched: `git diff --name-only HEAD | xargs -I{} grep -l 'thing-you-changed' README.md AGENTS.md DOCKER_HUB.md .gitea/README.md .env.example`. If a doc says "four variants" / "two phases" / "runs on amd64 only" and your change made that no longer true, fix it in the same commit.
 - **GitHub/Gitea-sourced binaries float by default** — gosu, fzf, git-lfs, nvim, bat, eza, zoxide, uv, gitea-mcp, Go, oh-my-opencode-slim all default to `latest`. Each build-time install step reads the `/releases/latest` Location redirect (or the go.dev JSON feed for Go) and derives the concrete version. Use the same `ARCH` case-switch pattern for multi-arch support (amd64/arm64). Intentional pins: `OPENCODE_VERSION` (drives the image tag), `NODE_VERSION=22` (major pin), `DEBIAN_VERSION=trixie-slim` (OS base). Adding a new upstream tool: follow the existing floated-version pattern, don't hardcode a specific tag.
 - **Resolved versions are logged by the smoke test** — `scripts/smoke-test.sh` prints a "Resolved component versions" table as its first step. CI logs always capture what got baked into a given image even when ARGs default to `latest`.
 - **Shell scripts use `set -euo pipefail`** — both entrypoints are strict. Errors in volume chown or SSH permission operations are intentionally suppressed with `|| true`.

+## v1.15.6 — 2026-05-21
+
+opencode 1.15.4 → 1.15.6 bump (two upstream patch releases) plus two workflow improvements that landed on `main` between v1.15.4b and now. No image-content changes beyond the version bump; cache hit expected on `base-35ee5fe7861a` (no `Dockerfile.base` or `rootfs/` edits).
+
+- **Bump:** opencode 1.15.4 → 1.15.6 (`OPENCODE_VERSION` in `Dockerfile.variant`). The `with-pi` and `omos-with-pi` variants will also implicitly pick up pi 0.75.3 → 0.75.4 since `PI_VERSION=latest` resolves at build time.
+- **CI: defensive `__pycache__` and macOS-metadata filter in `base-decide` hash compute.** `find rootfs -type f` previously included gitignored junk like `rootfs/__pycache__/*.pyc`, `.DS_Store`, and `._AppleDouble` files — which CI's clean checkout never sees. This bit us during v1.15.4 debugging when a stale `generate-config.cpython-314.pyc` on the local rootfs/ produced `base-3605aa6b6ab1` while CI computed `base-35ee5fe7861a`. The filter is a no-op on a clean tree (verified to still produce `35ee5fe7861a` post-filter), but defends against future stale-pyc / Finder-touched-rootfs hash mismatches. `.gitea/README.md` updated in lockstep. (commit `b6e4d89`)
+- **AGENTS.md: documentation drift sweep as explicit pre-commit workflow step.** Codifies the rule that non-release commits must also grep docs for stale claims about behaviour they change, with concrete repo-specific drift hotspots. Companion clause added across the wider repo set (cloud-init, ansible, pi-devbox, pi-extensions, pi-toolkit, cli_utils, proxmox) the same day. (commit `90e5a1f`)
+- **First release that exercises both the pinned-crane install (T14, v1.15.3) and the skip-promote-on-cache-hit guard (T15, v1.15.4) on this CI run path** — still cache-hit on base, so `promote-base-latest` should remain skipped via T15 and the pinned crane install will only fire when a real base rebuild happens.
+
+## v1.15.4b — 2026-05-18
+
+Recovery release for v1.15.4 — the `omos-with-pi` variant landed at >3500 MB and tripped the smoke threshold, so `smoke-omos-with-pi` and `build-variant-omos-with-pi` were skipped. The other three variants (base, omos, with-pi) published cleanly. Plus a latent workflow bug fix exposed by the partial publish.
+
+- **Smoke threshold bump:** `omos-with-pi` 3500 → 3700 MB. Compounded growth: opencode 1.15.0 → 1.15.4 (4 patch versions) plus pi 0.74.0 → 0.75.3 (minor + 3 patches) both added a few MB each, and they sum in the omos-with-pi variant. Same pattern as previous threshold bumps (v1.14.31c, v1.15.0b); restores ~150 MB headroom.
+- **Workflow fix — `update-description` no longer skips on partial publish.** Pre-existing latent bug: `update-description.needs` includes all four `build-variant-*` jobs, and gitea Actions' default behavior is "skipped need ⇒ skip dependent". When `build-variant-omos-with-pi` got skipped (because its smoke failed), `update-description` cascaded into a skip even though the job's `if:` condition (`tag pushed`) was true. Result: Hub description wasn't refreshed on v1.15.4 despite three variants publishing. Fix: wrap the `if:` in `always() && needs.build-variant-base.result == 'success' && ...` so the job runs as long as the base variant published, regardless of what other variants did.
+- **Same fix applied to `promote-base-latest`** — had the identical latent bug. Currently masked by the cache-hit skip, but would have surfaced on a real-base-rebuild release with a single failed variant.
+- No image-side changes from v1.15.4. Cache hit on the same base hash (`base-35ee5fe7861a`).
