## Problem
The arm64 `build-all` pipeline fills the macmini (gaia) host disk despite an 8h prune.
Root cause is not images or job volumes: it is the persistent dep-cache volume, specifically `pkgcache/R/pkgcache/_metadata`, which grew to ~165 GB.
`{pkgcache}` mints a new content hash for the "patched" binaries repo on every PACKAGES change, so each per-package build writes a fresh ~70 MB `pkgs-<hash>.rds` (+ `patched-<hash>/`) that is never evicted (2407 snapshots observed).
When the disk hits 100% OrbStack stops and the on-host prune can no longer connect to the daemon, so it never self-heals.
## Change (Workstream A of the disk-fill fix)
- Add `trim_pkgcache_metadata()` to `local/r-minor-helpers.R`: keeps the newest `keep` (default 20) `patched-*`/`pkgs-*.rds` entries under `_metadata`, deleting only entries older than `min_age_secs` (default 600s) so it never races the up-to-4 concurrent split-jobs sharing the volume.
Preserves `pkg/` downloads and the stable CRAN/BioC/INLA repo dirs.
No-op when `R_PKG_CACHE_DIR` is empty (amd64) or `_metadata` is absent (first run).
- Call it every 25 packages inside the build loop in `local/build-all.R`.
- Add a defensive start-of-run cleanup of `_metadata/patched-*` + `pkgs-*.rds` to the two workflows that mount the persistent volume (`build-all-versions.yaml`, `build-all-versions-install-deps.yaml`).
Only these paths are touched; `process-updates.yaml`/`weekly-rebuild-missing.yaml` (no persistent volume) are unchanged.
Follow-ups (separate workstreams): on-host self-healing prune watcher + OrbStack disk cap (ansible), and Prometheus/Grafana alerting (k8s-talos).
Upstream: bincraft patched-repo hash churn is the true source fix.
New unit tests (6) for the helper; full suite 24/24 green.

## Summary
Stop hardcoding the bincraft version. Every `.crow` workflow and the build-one image pinned `@vX.Y.Z` (and a `packageVersion() != "X.Y.Z"` guard), so each bincraft release meant editing the version in ~8 places — and it was easy to miss one (the Dockerfile lagged at v4.2.1; v4.4.1 shipped without the empty-env fix because of exactly this churn).
## Change
New `local/install-bincraft.R` resolves the **latest release tag dynamically**:
- `git ls-remote --tags` on the public repo (no token),
- keep `vX.Y.Z` tags, pick the highest version (filtered/sorted in R for portability, not via git `--sort`/refspec which behaved inconsistently under `system2()`),
- `pak::pak("git::…@<latest>")` — idempotent on the git ref, so re-runs keep the package unless a newer tag exists.
All call sites now invoke the helper instead of a pinned version:
- `.crow/build-all-versions.yaml` (primary + per-minor pass)
- `.crow/build-all-versions-install-deps.yaml`
- `.crow/process-updates.yaml` (primary + per-minor pass)
- `.crow/weekly-rebuild-missing.yaml`
- `.crow/archive-missed-packages.yaml`
- `docker/build-one.Dockerfile` (ships the helper into the image; `ensure_bincraft` sources it)
## Effect
Tag a new bincraft release → the next CI run / `just rebuild` picks it up automatically. No more pin edits, and no more "forgot to bump the Dockerfile" drift.
## Verified
- Resolver returns the current latest tag (`v4.4.2`) via `git ls-remote` + R-side version sort.
- All five workflow YAMLs parse; helper R parses; air/editorconfig clean.
Note: this tracks the latest **tag**, so cutting a release is still the deliberate gate — CI won't pick up un-tagged main.

## Summary
Silences the recurring `OpenTelemetry error: there is no package called 'otelsdk'` warnings during builds.
## Root cause
The `build-env-*` images configure an OTel exporter (traces/logs/metrics), but `otelsdk` (the R OTel SDK backend) isn't installed. pak's `otel` instrumentation therefore tries to load `otelsdk` on every run and logs the error, falling back to a no-op.
`OTEL_SDK_DISABLED=true` (already set in `build-one.Dockerfile`) does **not** help — the R `otel` package ignores it and gates purely on `OTEL_R_<SIGNAL>_EXPORTER` (then the standard `OTEL_<SIGNAL>_EXPORTER`). When that resolves to a real exporter (`otlp`/`http`/…) with no SDK present, you get the error.
## Fix
Set `OTEL_R_TRACES_EXPORTER`, `OTEL_R_LOGS_EXPORTER`, and `OTEL_R_METRICS_EXPORTER` to `none` so the R otel providers are clean no-ops:
- `docker/build-one.Dockerfile` — exported alongside the existing OTel var.
- `.crow/process-updates.yaml`, `weekly-rebuild-missing.yaml`, `build-all-versions.yaml`, `build-all-versions-install-deps.yaml` — added to each step's `environment` block.
Using the R-specific variables (not the standard `OTEL_*_EXPORTER`) keeps OTel intact for any non-R tooling in the images.

## Summary
Adds the curated **patch registry** and wiring that drives bincraft's new package-patching mechanism (see bincraft PR `feat/package-patching`).
Lets specific packages be patched (env/configure/Makevars overrides or source diffs) before pak installs them — including as transitive dependencies — so compiler-/OS-specific failures like RcppParallel's bundled TBB stop cascading.
## What's included
- `local/patches/registry.json` — initial entry: RcppParallel with `RCPP_PARALLEL_USE_TBB=0` for alpine / ubuntu-2604, plus `local/patches/README.md` schema docs.
- `local/validate-patches.R` — validates schema, referenced patch files, and ambiguous overlaps; clean failure + exit 1 (no stacktrace).
- `.pre-commit-config.yaml` — a `validate-patches` hook (re-runs when the registry or the validator changes).
- `local/build-one.R` / `local/build-all.R` — pass `patches = "local/patches"` to `bincraft::build_binary_package()`.
- `specs/2026-06-30-package-patching-design.md` and `plans/2026-06-30-package-patching-implementation.md`.
## ⚠️ Merge ordering (blocker)
This PR adds a `patches = ...` argument to `build_binary_package()` calls.
The `.crow/*.yaml` workflows currently pin bincraft **v4.2.3**, which does not accept that argument — CI will error with `unused argument (patches=...)` until:
1. bincraft **v4.3.0** is released (PR `feat/package-patching`), and
2. the pin is bumped in `.crow/build-all-versions-install-deps.yaml`, `.crow/build-all-versions.yaml`, and `.crow/process-updates.yaml`.
The `.crow` pin bump will be added to this PR once bincraft v4.3.0 is tagged. Do not merge before then.

The function defaults to Hetzner S3 with HETZNER_S3_*_K3S env vars that
are not set in these workflows, so paws failed with "No compatible
credentials provided". Pass the B2 endpoint/region/bucket and
B2_S3_* secrets explicitly, matching the other S3 calls. Also use
set_codename(NULL) for the build-all-versions codename so it matches
the S3 repo path.
## Summary
Two changes:
1. **`OS`/`OS_VERSION` manual-run dropdowns** — give these form variables explicit `options:` lists (like `target_arch` and `R_VERSION`), so the manual-run form shows dropdowns instead of free-text, in both `build-all-versions.yaml` and `build-all-versions-install-deps.yaml`. Crow form variables are independent (no cascading), so the operator still has to pick a coherent `OS` + `OS_VERSION` combination (e.g. `redhat` + `9`, not `alpine` + `jammy`).
2. **Repairs `main`** — the crow fix from PR #96 (`bc2f6f1`) was lost when that PR was squashed (only the first commit was captured). As a result `main` currently carries the `OS: ${OS}` env vars that break Crow parsing (`unable to parse variable name`) and the unfixed `build-all.R`. This PR re-applies that fix: drop the env additions and derive `platform`/`arch` inside `build-all.R` from the container (bincraft codename → platform mapping + `Sys.info()` arch).
## Notes
- `OS_VERSION` options are quoted strings so tags like `8`/`9`/`10` aren't parsed as integers.
- Validated: both YAMLs parse, `build-all.R` parses.

## Summary
Fixes the recurring `build-all-*` failure on agents where `build-all-versions-install-deps` did **not** run.
Both symptoms in the logs — `Parameter 3 does not have length 1` (repeated, in the metadata DB queries) and `argument is of length zero` (system-dependency install) — were the same bug: inside bincraft, `platform` was zero-length. `local/build-all.R` calls `build_binary_package()` without passing `platform`, so bincraft resolves it from the container codename. The primary build step never (re)installed/pinned bincraft and relied on whatever sat in the **per-agent** cache volume; `depends_on` only orders steps, it does not co-locate them on the same agent, so a job landing where install-deps never ran got a stale bincraft that left `platform` empty.
## Changes
- **`build-all-versions.yaml`**: pin bincraft `@v4.2.3` in the primary build step (mirroring the R-minor pass and `process-updates.yaml`), so every agent uses a known-good bincraft regardless of where install-deps ran.
- Align the R-minor pass `v4.2.2 → v4.2.3`.
- Export `OS`/`OS_VERSION`/`ARCH` as runtime env vars — previously only available for `${...}` interpolation, so `build-all.R`'s already-built dedup query matched platform `"-"` and skipped nothing.
- Fix the unarchive call: pass the codename via `bincraft::set_codename(NULL)` instead of the malformed `paste(OS, OS_VERSION)` (`"alpine 3.24"`), matching `archive-missed-packages.yaml`.
- **`build-all-versions-install-deps.yaml`**: pin install-deps to `@v4.2.3` (was installing HEAD), so the precomputed snapshot and per-agent library stay consistent pipeline-wide.

## Summary
- Switch crow workflow placement from a per-agent label (`agent: ${AGENT}`) to a group label (`group: rpkgs-${ARCH}`), so jobs target the `rpkgs-amd64` / `rpkgs-arm64` agent pools instead of a single named agent (`artemis`/`gaia`).
- Remove the now-unused `AGENT` matrix variable from all build/process/weekly workflows.
- Update header comments to reflect group-based placement.
Agents opt into a pool via `CROW_AGENT_LABELS="group=rpkgs-<arch>"`. The group name derives from each matrix row's `ARCH`, so adding or replacing agents no longer requires touching the workflow files.

## Summary
Consolidate the four `build-all-versions*` files into two, mirroring the matrix approach used for the process-updates / weekly families:
| Before | After |
|---|---|
| `build-all-versions-amd64.yaml` + `build-all-versions-arm64.yaml` | `build-all-versions.yaml` |
| `build-all-versions-install-deps-amd64.yaml` + `-arm64.yaml` | `build-all-versions-install-deps.yaml` |
`ARCH` becomes a matrix axis carrying the per-arch differences: `agent` (artemis/gaia), `BACKEND` (kubernetes/docker), and `R_PKG_CACHE_DIR`. Build-all keeps its `SPLIT_INDEX` parallelism, so its matrix is ARCH x SPLIT = 8 rows; only the rows matching the selected arch run.
**Invocation unchanged.** Routing uses the existing task selector `task == "build-all-${ARCH}"`, so `--var task=build-all-amd64 ...` still runs exactly the amd64 rows. `OS` / `OS_VERSION` / `R_VERSION` / `K8S_INSTANCE_TYPE` are still passed via `--var`. (You can drop `--var ARCH=...` now — arch comes from the matrix/task.)
**No cron.** These pipelines are manual-only, so there are no scheduled runs to affect.
## Validation before merge
Same matrix-interpolation-in-`when`/`labels` mechanism validated for #92, plus it now relies on per-row `agent`/`BACKEND` selecting the right execution backend (kubernetes for amd64, docker for arm64). Before merge, on this branch trigger a small `task=build-all-arm64` run and confirm it lands on the gaia/docker backend (and amd64 on artemis/kubernetes). Originals are in git history for rollback.
Note: `archive-missed-packages.yaml` was already a single consolidated matrix file (cron + manual) and is left untouched.
