osobhandClaude Sonnet 5 ef02b22b72 Fix dashboard disk usage overstating used space fleet-wide
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
Reported by the operator: dashboard's "used" figure for morpheus
didn't match `df`. Root cause: filesystem_usage() computed
`used = total - f_bavail`. f_bavail is space available to an
*unprivileged* user, which excludes ext4's reserved-blocks-for-root
margin (~5% of the filesystem by default) -- so that formula folded
the entire reserved margin into "used" on every node, not just
morpheus. Worse on bigger disks: this overstated tank's usage by
~1GB less noticeably relative to its 1.9TB size, but the same
absolute-percentage bug applies everywhere.

`df`'s Used column is `total - f_bfree` (raw free blocks, reserved
or not) -- matching that formula is what makes the dashboard agree
with `df` instead of silently running high. `available_bytes` still
reports f_bavail (what's actually writable), unchanged.

Verified against `df -h /` on all three nodes post-fix: tank
93.6GiB vs df's 93G, architect 93.6GiB vs 94G, morpheus 135.5GiB vs
136G -- all now agree within rounding.

osobhandClaude Sonnet 5 11a259b762 Recover replication baseline from remote when locally pruned
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 2s
Details 
Found during a routine fleet health sweep: tank's daily replication
to architect had silently broken. replicate_to_cold() records the
last-replicated snapshot name in a local state file and reuses it as
the incremental send base next time -- but never handles the case
where local snapshot retention (snapshot_retain_hours = 24) prunes
that exact snapshot before the next replication run. When that
happens it silently falls back to a FULL send, which then hard-fails
against a non-empty destination ("must destroy them to overwrite
it").

Root cause of the timing gap: the daemon's replication tick is a
24-hour interval, same order of magnitude as local retention. Every
claw-store.service restart resets that tick's countdown without
resetting the hourly-snapshot pruning tick, so a day of frequent
restarts (routine during active deployment work) is enough for the
two to drift out of sync -- the recorded baseline ages out locally
before replication ever gets to reuse it.

Fix: when the recorded baseline is gone, query the remote's actual
snapshot list over SSH (new ZfsOps::list_remote_snapshots) and find
the newest snapshot both sides still share by tag, rather than
giving up and attempting a full send. Only truly falls back to full
when no common snapshot exists anywhere. Verified live against tank
-> architect: correctly recovered daily-2026-08-01-0000 as the base
and completed an incremental send.

Added test coverage for all three paths (recorded baseline present,
recovered from remote, no common snapshot found) -- replicate_to_cold
had none before this, since LAST_REPLICATED_PATH was a hardcoded
absolute path with no way to inject a test double. Split into a
public wrapper plus replicate_to_cold_with_state_path() so tests can
use a temp file instead of touching real /var/lib/claw-store state.

osobhandClaude Sonnet 5 e5fcb8b3f4 Fix stdout/stderr ordering in ShutdownPrepCheck
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
Command::output() captures stdout and stderr as two separate
buffers. check() was concatenating stdout-then-stderr, which throws
away chronological order entirely -- every stderr line (e.g.
"Error: send_to_host not set" from `claw-store replicate` on a node
with no downstream replication target, which is normal and expected
on architect) landed at the very end of the report regardless of
when it actually printed, making a mid-script, already-handled
condition look like a failure that happened after "DRY RUN
COMPLETE".

Fix: invoke via `bash -c "script --dry-run 2>&1"` so stderr merges
into stdout inside the shell, before either stream reaches us --
true chronological order preserved, single buffer to read.

Verified on architect: the send_to_host message now appears exactly
where it happens, inside the "taking final snapshot + replicating"
step, with DRY RUN COMPLETE correctly last.

osobhandClaude Sonnet 5 f38efc7096 Honor zfs_dataset = "none" instead of erroring; surface shutdown-prep panel from fleet view
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 4s
Details 
Two problems surfaced while checking on the fleet after the shutdown-
prep button PR:

1. morpheus is configured with zfs_dataset = "none" (it has no ZFS
   pool -- warm tier is a plain directory on the LVM root volume),
   but nothing in the code actually implemented that as a sentinel.
   cmd_snapshot/cmd_replicate and the daemon's periodic snap/repl
   ticks always tried real zfs/zpool calls regardless, producing
   "zfs: command not found" errors on every hourly tick and in the
   shutdown-prep report. WarmConfig::zfs_enabled() now gates all four
   call sites; a non-ZFS node gets a clean "nothing to
   snapshot/replicate" instead of a raw shell error.

2. safe-shutdown-prep.sh's zpool-health step now checks `command -v
   zpool` first instead of leaking "zpool: command not found" into
   the report.

3. "we don't see the button" turned out to be page confusion: the
   shutdown-prep panel lives on the per-node detail page
   (/v2/nodes/<name>), not the root Fleet Health landing page. Added
   a small "view detail · maintenance & shutdown prep →" hint to the
   bottom of every NodeCard so it's discoverable without already
   knowing to click through.

Verified against tank, architect, and morpheus -- morpheus's
shutdown-prep --dry-run report is now clean (no "command not found"
lines) both when run locally and via cross-node RPC from tank.

osobhandClaude Sonnet 5 4ea1cbed2e Add shutdown-prep button to dashboard-v2 NodeDetail
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
Wires safe-shutdown-prep.sh into the dashboard so an operator can
prep a node for hardware maintenance from a browser instead of SSH.

New RPC methods (0x20/0x21):
- ShutdownPrepCheck runs `--dry-run` to completion and returns the
  full report. Never stops anything, safe to call repeatedly.
- ShutdownPrepExecute starts the real run detached (`systemd-run
  --user --scope --collect`), placing it in a cgroup outside
  claw-store.service's own -- the script's own step 6 stops that
  service, i.e. the process that would otherwise be running it, so
  it has to survive its own parent dying. Returns immediately with
  a "started" message; full output lands in
  /var/lib/claw-store/shutdown-prep.log for whoever's at the machine
  once it's gone dark, since there's no way to stream a live result
  past the point the daemon stops itself.
- Execute double-checks confirm_node_name against the peer's own
  configured name server-side, on top of the aggregator's own path
  match -- defense in depth for a highly consequential action.

Aggregator endpoints (admin-token gated, AuthedCaller::require_admin):
  POST /api/v2/node/:name/shutdown-prep/check
  POST /api/v2/node/:name/shutdown-prep/execute

Frontend: ShutdownPrepPanel on NodeDetail. Check button always
enabled; the real "stop services" button only unlocks after a ready
check, and additionally requires typing the exact node name to
confirm before it's clickable.

Also fixes a script bug found while testing this against the live
daemon process (not caught in manual interactive-shell testing): the
zpool-detection line parsed raw `mount` output positionally, which
returned the wrong field under the daemon's process context for
reasons that didn't reproduce interactively. Switched to
`df --output=source`, which is stable across both.

Verified end-to-end against tank, architect, and morpheus, including
cross-node targeting (tank's dashboard successfully triggered a
check on morpheus over the fleet RPC layer).

osobhandClaude Sonnet 5 fe815db981 deploy: add safe-shutdown-prep.sh for hardware maintenance
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 2s
Details 
Node-local script an operator runs before powering a node off for
parts replacement. Guards against shutting down mid-build or with
un-pushed sync jobs, takes a final snapshot + replicates to cold,
stops the maintenance timers and dashboard, gracefully stops the
daemon (giving gossip its TimeoutStopSec=60 window to announce
departure to peers instead of relying on the 10s failure-detector
timeout), and cleanly unmounts FUSE before declaring the node safe
to power off. --dry-run runs every check for real but only prints
what the stop/unmount steps would do.

osobhandClaude Sonnet 5 334cd068d2 dashboard-v2: fix asset base path to match backend /v2 mount
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 6s
Details 
Console errors on the live dashboard (architect:7700) turned out to
be two separate problems layered together:

1. The deployed static bundle wasn't built from this repo at all --
   it called /api/v2/hot-refs, /api/v2/anomalies, and
   /api/v2/node/*/metrics-history, none of which exist anywhere in
   this codebase on any branch (checked via `git log --all -S`).
   Someone built and shipped a frontend straight to
   /usr/share/claw-store/v2 without ever committing the source.

2. Separately, this repo's own committed vite.config.ts had a latent
   bug: `base: '/clawstor/'`, contradicting its own comment ("served
   by claw-store serve under /v2/*") and the actual backend mount in
   serve.rs (`nest_service("/v2", ...)`). Checked `tailscale serve
   status` on tank + architect -- neither has ever proxied a
   /clawstor path, so that base would have 404'd every asset the
   moment anyone rebuilt and redeployed from source.

Fix: base = '/v2/', matching the real mount. Rebuilt and redeployed
to tank + architect (orphaned build backed up to
/usr/share/claw-store/v2.bak-orphaned on both).

osobhandClaude Sonnet 5 bb24c77676 Include self in dashboard-v2 fleet aggregation
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
V2State::from_config built its peer fan-out list solely from
[[cluster.peers]], which by definition never includes the local
node. Result: hitting a given node's /api/v2/fleet directly always
omitted that node from its own fleet view, even when perfectly
healthy -- looked like "node X is missing" from the dashboard when
X just never queried itself.

Fix: synthesize a self PeerEntry from the node's own gossip bind
address and include it in the fan-out, same as any other peer.
peer_rpc_addr()'s existing +1 port convention resolves it to the
same bind_rpc_lan/bind_rpc_tailscale the daemon already listens on.

osobhandClaude Sonnet 5 75d822d0f2 Fail fast when cluster gossip bootstrap fails 
Bind failures at startup are almost always a boot-time race against
DHCP/network-online (bind address not yet assigned to the interface).
Previously the daemon caught the error and kept running in a degraded
state with no gossip, RPC, or Prometheus endpoint and no visible
failure signal. Now it propagates the error so the process exits and
systemd's Restart=on-failure retries once the network is actually up.

Omar SobhandClaude Sonnet 4.6 2f7eabf034 fix(cluster): bind RPC on main LAN addresses so serve_v2 aggregator can reach peers
Build with clawstor cache / Cargo build (clawstor-cached) (push) Failing after 3s
Details 
serve_v2::peer_rpc_addr derives each peer's RPC socket as lan_addr.ip():port+1.
Architect and Tank were bound on their 10G fabric NICs (10.10.0.9/10.10.0.10)
but the peer entries only carry the main-LAN gossip address, causing the
aggregator to time out when probing Tank and present a stale cert to Morpheus.
Changing bind_rpc_lan to the main-LAN addresses (10.0.0.13/10.0.0.14) fixes both.

Omar SobhandClaude Sonnet 4.6 7902c2e395 feat(fleet): switch all nodes to new-gen clawstor with centralized dashboard-v2
Build with clawstor cache / Cargo build (clawstor-cached) (push) Failing after 10m3s
Details 
- All three node configs (architect/tank/morpheus) now include [cluster]
  section with correct 10G fabric IPs, mTLS TLS paths, and blob store root.
  Architect binds gossip on 10.0.0.13:7701 and RPC on 10.10.0.9:7702 (10G
  to Tank); Morpheus uses LAN 10.0.0.5 (no direct 10G).

- claw-store.service: updated description, adds clawstor-deploy to
  ReadWritePaths, removes NoNewPrivileges (needed for sudo zfs snapshot).

- claw-store-serve.service: adds --v2-static-dir /usr/share/claw-store/v2
  so the aggregator serves dashboard-v2 ("clawstor · command center") at /v2/.

- claw-fuse.service: new unit, uses correct --data-dir + --mount flags.

Deployed to Architect, Tank, Morpheus. Fleet CA re-initialized; new certs
signed for all three nodes and distributed. Dashboard accessible at
http://100.104.171.32:7700/v2/ aggregating Tank + Morpheus via /api/v2/fleet.

Omar Sobh 5c9bc7eb9c Phase 9 R1b: aggregator fan-out for RepoEnsure/RepoRelease 
Layers HTTP over the R1a per-peer primitive so external callers
(clawmates, gitea runners, ops tooling) speak one URL to the
aggregator instead of dialing every peer.

Endpoints (require v2 auth, same middleware as tags/sessions):
  POST /api/v2/repos/ensure   {url, git_ref, workspace?}
  POST /api/v2/repos/release  {url, git_ref, workspace?}

Namespaced tokens are pinned to their own workspace (workspace omitted
in body → derived from token; explicit mismatch → 403). Admin/open
callers must supply workspace explicitly.

Reply shape mirrors the tag fan-out (FanoutReply) with per-peer
{peer, ok, path?, head_sha?, cached?, removed?, error?}. all_ok is
true iff every peer succeeded.

Also adds client wrappers call_repo_ensure/call_repo_release in
cluster/rpc/client.rs used by the aggregator's fan-out.

New per-peer RPCs to shallow-clone a (url, git_ref) under a caller-
provided workspace namespace, and to release the checkout. Fleet
fan-out via the aggregator ships separately in R1b.

- src/cluster/repo_ensure.rs: request/reply types + derive_path
  (traversal-safe, blake3-hashed url segment), ensure_repo (cache
  hit → rev-parse HEAD, else remove-and-reclone with 5-min timeout),
  release_repo (idempotent rm)
- src/cluster/rpc.rs: Method::RepoEnsure=0x1e, RepoRelease=0x1f,
  RpcRouter::with_repo_root builder, two dispatch arms returning
  NotConfigured when repo_root is unset
- src/cluster.rs: pub mod repo_ensure
- src/actions.rs: fix pre-existing test-only Config init missing the
  aggregator field (unblocks lib tests)

Tests: 6 unit tests covering path derivation determinism, ref/url
independence, traversal safety, and sanitizer edge cases. All pass.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 34s
Details 
Backend:
* New DashboardProject { repo, cache_bytes, fingerprint_count,
  refs, first_seen_unix, last_seen_unix, tier }.
* Handler build_projects() joins ref-tracking with the ref-store
  and blob-store: for each recorded fp, resolve fp → blob-id via
  RefStore::{get_stamped, get} then sum blob sizes per repo.
* Tier is a wall-clock function of last_seen_unix:
    active < 24h, recent < 7d, else idle.
* DashboardStorageReply gains `projects: Vec<DashboardProject>`
  (serde-default so older clients still parse).

Aggregator:
* New /api/v2/projects endpoint. Fans out DashboardStorage to
  every peer, tags each project row with its originating node,
  returns hottest-first.

Frontend:
* New ProjectsPanel component appended to the FleetHealth
  landing. Groups by repo, one row per project with tier badge
  (active/recent/idle), per-node pill badges, cache-size sum,
  ref list, last-activity age.
* Empty state explains how to populate: claw-cargo build with
  --repo + --git-ref (or CLAWSTOR_REPO/CLAWSTOR_GIT_REF env
  vars in CI).

Data populates automatically as each cache-put runs. Existing
demo entry on tank (clawverse/clawstor · main · c384a4...) will
surface after redeploy.

Reworks the SPA around the new DashboardStatus fields. The

disk gauges, mount ✓/✗, cache hit rate, next scheduled job.
No hex, no primitives.

Nav restructure:
* Primary: 'Fleet health' (just the landing).
* 'View Advanced ▾' dropdown reveals: Blobs / Tags / Refs /
  Snapshots / Ref-tracking. Routes moved under /advanced/*.

New components:
* StorageBar — horizontal used/total bar with pinned/evictable
  split, health-color threshold at 60/85%.
* NodeCard — traffic-light dot + disk + hot tier bars + mount
  state + cache hit rate + next-timer countdown. Whole card
  is a link into node detail.

New CommandCenter:
* Fleet-wide storage roll-up card (sum of every node's disk).
* Grid of NodeCards.
* 10s poll cadence retained from previous version.

Existing StorageBrowser + RefTrackingPage moved behind
/advanced/* routes; internal component code untouched.

Omar Sobh 9d6badf2aa FleetHealth PR 1 (backend): human-oriented DashboardStatus fields
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 17s
Details 
Extends DashboardStatus with the primitives the FleetHealth
landing needs. All new fields serde-default to None/[]/false so
old clients (aggregator running an older build) still parse the
reply.

Added fields:
* filesystem  — statvfs on blob_store_root: total / used / avail.
* hot         — {used_bytes, max_bytes, pinned_bytes?}, read from
                gossip (already published every 10s).
* mount       — probes /proc/mounts for ~/clawstor-mount by
                convention. { path, active }.
* cache       — router.metrics().snapshot() summarised as
                {hits, misses, bytes_served, bytes_ingested,
                hit_rate}. hits = get_ref+get_tag+get_chunk hits,
                misses similarly — the counters that matter for
                claw-cargo build outcomes.
* timers      — well-known set (scrub / gc / ref-sweep /
                snapshot-rotate) queried via `systemctl --user
                show`. next_fire_unix + last_result per timer.

Aggregator NodeStatusV2 mirrors the same fields verbatim so the
new frontend can consume them without further backend hops.

Follow-on PRs:
* PR 2 — new FleetHealth landing page + node-detail rework
* PR 3 — polish (pinned_bytes derivation, activity timeline,
         per-repo grouping)

All storage rows now carry a 'node' field from the aggregator.

Omar Sobh 1211f0d891 dashboard-v2: DashboardStorage RPC + aggregated /storage/* endpoints
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 18s
Details 
Storage tabs 404'd because the aggregator only had /fleet + /node/:name
after the pivot. Adds:

* New RPC method DashboardStorage = 0x1d — one round trip returns
  tags (full), snapshots (full), ref-tracking (full), blobs
  (first 200 by id), refs (first 200 by fp) for the responding
  daemon.
* Client wrapper call_dashboard_storage.
* Aggregator fans out to every peer, tags each row with the
  originating node, sorts + returns:
    GET /api/v2/storage/blobs
    GET /api/v2/storage/tags
    GET /api/v2/storage/refs
    GET /api/v2/storage/snapshots
    GET /api/v2/storage/ref-tracking

QuicClient promoted to Arc<QuicClient> inside V2State so the
per-peer JoinSet can hand it to spawned tasks without recreating
the endpoint.

Omar Sobh a2114b918d dashboard-v2 PR 3: fleet aggregator via DashboardStatus RPC
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 15s
Details 
Pivot from per-node dashboard to single-pane-of-glass. The
aggregator (typically the operator's laptop) holds a fleet-CA
leaf cert + the peer list; each dashboard request fans out to
every peer over the existing QUIC/mTLS cluster port and issues
the new DashboardStatus RPC. Peers don't need to run any HTTP
server of their own.

Backend:
* New RPC method DashboardStatus = 0x1c
* Server handler reads BlobStore / TagStore / RefStore /
  SnapshotStore / RefTracking counts + on-disk bytes + rustc
  release. Cheap: 5 filesystem walks per request.
* Client wrapper call_dashboard_status
* serve_v2 rewritten as aggregator: V2State holds a QuicClient +
  peer list from `[[cluster.peers]]`. Endpoints:
    GET /api/v2/fleet             fan-out to every peer, parallel
    GET /api/v2/node/:name/status one peer, on-demand
  Failed peers surface as { online: false, error: "..." } cards
  instead of dropping.

serve.rs graceful degrade: v2 aggregator routes only mount when
[cluster.tls] is set. Static SPA still serves at /v2/* even
without an aggregator config so operators see the SPA's built-in
"config missing" error.

Deployment model (this session):
* Aggregator runs on quantum (Mac) with a signed leaf.
* Fleet daemons run cluster-only — no HTTP dashboard anywhere
  on tank/architect/morpheus. The clawstor-dashboard.service
  systemd units on the fleet are being retired.

Frontend rework to consume /api/v2/fleet ships in the next PR.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 16s
Details 
React 19 + Vite + Tailwind + wouter (tiny router, no external
state library). Consumes the /api/v2/* endpoints shipped in PR 1.
Serves under /v2/* so the legacy dashboard at / stays live.

Pages:
* CommandCenter (/)      — fleet strip + this-node stat tiles
* NodeDetail (/nodes/:name) — per-node deep dive
* StorageBrowser (/storage/{blobs,tags,refs,snapshots}) — tables
  with prefix filter
* RefTrackingPage (/refs/tracking) — grouped by repo

Backend changes:
* claw-store serve grows --v2-static-dir <path>
* build_app split into build_app_with_v2 for the extra static
  mount
* /v2/* falls through to index.html so wouter client routing works

New systemd unit: clawstor-dashboard.service. Points at both
static dirs; installs on any node.

dashboard/ (legacy) untouched. dashboard-v2/ built to
target/dashboard-v2/dist for deploy.

Deploy sequence per node:
1. cp target/release/claw-store  ~/clawstor-deploy/
2. rsync dashboard-v2/dist/      ~/clawstor-deploy/dashboard-v2/
3. cp deploy/systemd/clawstor-dashboard.service ~/.config/systemd/user/
4. systemctl --user daemon-reload && enable --now clawstor-dashboard.service

Cross-node fan-out for /api/v2/node/:name/status is PR 3.
Action POSTs (scrub/gc/snapshot/pin) are PR 4.

Omar Sobh b431475af7 dashboard-v2 (PR 1): design doc + backend read-only endpoints
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 17s
Details 
Kicks off the single-pane-of-glass command-center rewrite. Legacy
/api/* handlers untouched — v2 is additive so cutover is safe.

Doc: docs/dashboard-v2.md — design goals, endpoint spec, cutover
plan.

Backend: new serve_v2 module wired into serve.rs. Endpoints:

  GET /api/v2/node/local/status
  GET /api/v2/node/:name/status         (fan-out: not-yet-impl)
  GET /api/v2/storage/blobs?limit&offset
  GET /api/v2/storage/tags?prefix
  GET /api/v2/storage/refs?limit&offset
  GET /api/v2/storage/snapshots
  GET /api/v2/storage/ref-tracking?repo

V2State opens BlobStore / TagStore / RefStore / SnapshotStore /
RefTracking under the daemon's blob_store_root + the conventional
subdirs (tags-db, refs-db). All handlers are single-node reads;
cross-node fan-out lands in PR 3.

+6 tests: status w/ seeded blob+snapshot, cross-node returns 501,
blobs pagination, tags prefix filter, snapshots list, ref-tracking
repo filter.

395 tests pass. serve.rs merges v2 routes onto the axum router
with shared CORS. Single-shot deploy on tank + architect will
expose /api/v2/* alongside the existing /api/*.

PR 2 = frontend rewrite consuming these endpoints.
PR 3 = fleet fan-out (cross-node aggregation via QUIC RPC).
PR 4 = action endpoints (POST scrub/gc/snapshot/pin).
PR 5 = cutover (deprecate legacy /api/*).

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 15s
Details 
README.md was still describing the pre-distributed ZFS-only
architecture (activate/deactivate cargo target dirs, SSH-based
tank→architect sync). Nothing about the distributed content-
addressed store, chunk-level dedup, QUIC/mTLS, snapshots, tags,
refs, FUSE mount, ref-tracking, Tailscale identity, or the
systemd timer set — i.e. everything shipped in Phases 1-8.

Full rewrite:
* What you get: 6 feature sections spanning storage/distribution,
  fingerprint-keyed cargo cache, human primitives, operations,
  roaming, reliability.
* One-paragraph architecture + link to ARCHITECTURE-v2.md.
* Fleet layout table (tank/architect/morpheus current state).
* Install: prereqs (Linux + macOS macFUSE), build, first-time CA
  bootstrap, config template with tailnet bind, systemd install
  recipe.
* Daily usage: claw-cargo build (env-driven for CI), pins,
  snapshots, integrity+repair, fleet-status.sh, FUSE mount layout.
* CLI reference table (28 commands across claw-store + claw-cargo
  + claw-fuse).
* Prometheus metrics list.
* Ongoing operations: 4 timers table with sequencing rationale.
* Testing: 389 tests, known pre-existing macOS failure.
* Design-docs pointer list.
* Contributing + license note.

Also:
* ARCHITECTURE-v2.md phase plan table: replaced weeks-estimates
  with ship-state (all ✅ shipped, dated).
* docs/runner-integration.md: added ref-tracking env-var section
  so CI wiring populates the nightly sweep.
* dashboard/README.md: replaced the Vite template boilerplate
  with actual dashboard context + note that it predates the
  current architecture.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
Live smoke on morpheus with the previous unit failed:
  Error: mounting FUSE at /home/osobh/clawstor-mount
  Caused by: Operation not permitted (os error 1)

But 'systemd-run --user' with the exact same binary worked, and
the manual invocation worked. The delta was our ExecStartPre
chain (mkdir + fusermount3 -u -z) — on some Ubuntu 24.04 builds
that combination poisons the subsequent mount syscall even with
the -z lazy flag + ignored exit code.

Fix: drop the pre-mkdir + pre-unmount. Operator creates the
mount dir manually once (documented in README). Restart handling
falls to systemd's Restart=on-failure + ExecStop unmount.

Verified live on morpheus with the minimal unit — active +
mount visible in <3s.

Cargo.toml: fuser dep now target-gated to Linux + macOS. macOS

umount, known differences (no AllowOther, unmount is 'umount'
not fusermount3 -u).

deploy/macos/claw-fuse.plist — launchd agent template
(RunAtLoad + KeepAlive) so ghost / macbook / smith can run the
mount the same way tank/architect do under systemd.

Default 'cargo build' (no --features fuse) still works on macOS
with no macFUSE installed — feature gate keeps the dep opt-in.

Omar Sobh 0e5e5982d8 Polish: extract src/lib.rs so bins reuse a proper library crate
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 2s
Details 
Historically every bin (claw-store, claw-cargo, claw-fuse)
re-declared the same 13-line 'mod ...' block at its own root.
Working but fragile — a new bin (or a new module) needed edits
in N+1 places and stayed one edit-slip away from silently
dropping something.

Now: src/lib.rs owns the shared module tree. Cargo.toml gets a
[lib] entry so cargo picks it up. claw_fuse.rs migrated as the
proof-of-concept — 13 mod lines → 4 use lines.

claw-store + claw-cargo bins still use their internal 'mod ...'
blocks and 'crate::...' paths — migrating them is mechanical
but noisy; deferred to a follow-on so this PR stays reviewable.
Both bins + tests continue to build unchanged.

387 tests pass.

Omar Sobh 3000021ac3 Phase 7g: weekly cluster-scrub systemd timer
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 11s
Details 
Deploy artifact. Sunday 04:00 local, Persistent=true so a
box that missed the wall-clock moment fires on next boot.

Timer + Service pair — both go under
~/.config/systemd/user/. The service is Type=oneshot; timer
drives it. Non-zero exit from cluster-scrub (integrity issue)
surfaces via systemd failed state; journalctl has the details.

README updated with install recipe.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 2s
Details 
<mount>/refs/<fp-hex>   file, content = blob that fp points at

Adds RefStore::list() unioning legacy refs/ and stamped refs-v2/.
FUSE wires the new dir. On lookup, tries get_stamped first then
legacy — matches the resolution order used by claw-cargo build.

Ref files piggy-back the blob inode (same content), so a hex
readable via /blobs/<hex> and /refs/<fp> shares the inode. cheap.

Omar Sobh b1fc463655 Phase 6d: systemd user unit for persistent FUSE mount
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 15s
Details 
Deploy artifact — not built into the binary tree. `deploy/systemd/
clawstor-fuse.service` + README with the install recipe.

Unit shape:
* Type=simple, blocks on the FUSE binary (unmount = SIGTERM).
* ExecStartPre = mkdir -p mount, best-effort lazy unmount of any
  stale prior mount (guards against a hard SIGKILL leaving the
  kernel with a dangling mount).
* Restart=on-failure, RestartSec=5 — recover from transient IO
  errors without operator involvement.
* Environment= for CLAWSTOR_FUSE_BIN / DATA / MOUNT so a
  `systemctl edit` drop-in retargets without editing the unit file.

Dependency chain: clawstor-fuse.service After= + Wants=
clawstor-cluster.service. FUSE reads only the on-disk state so
this is technically not needed for correctness — but keeps the
mount from spinning up on a node where the daemon is broken.

Omar Sobh 2c51f0917e Phase 6c fix: TagStore delete()/contains() also see stamped tags
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
Companion to the previous list/get fix. Same layer-split problem:
* delete() only unlinked tags/, leaving stamped tags-v2/ behind.
  Result: `unpin` prints \"no such tag\" for pins created via
  Phase 3c+ RPC even though the tag is right there on disk.
* contains() only checked tags/. Same false-negative.

Fix: both APIs now inspect BOTH layers. delete() unlinks
whichever files exist (either or both) AND removes the TTL
expiry sidecar if present. Returns true when anything was
actually removed.

Legacy behavior preserved: tests unchanged, 381 tests pass.

Omar Sobh 14a8221e00 Phase 6c fix: TagStore list()/get() see stamped tags
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 12s
Details 
Live smoke exposed the gap: `claw-cargo pin` writes to the
stamped store (tags-v2/, Phase 3c+) but `TagStore::list()` +
`get()` only walked the legacy `tags/` layer. Modern pins were
invisible to everything using those APIs — including the new
FUSE tag layer, but also `claw-cargo list-tags`.

Fix:
* list() now unions legacy + stamped entries (deduped by key).
  New private list_stamped_only() walks tags-v2/.
* get() falls through to get_stamped() when the legacy file is
  absent — modern pins resolve without callers knowing which
  layer stored them.

No API breakage: legacy tests still pass unchanged.
381 tests pass.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 11s
Details 
<mount>/tags/<sanitized-name>   ← file, content = current tag's blob

Layers atop the Phase 6a/6b mount. Operator can now `cat` a named
build cache without translating a tag → blob-id first:

  cat <mount>/tags/clawverse:main:latest-cache | tar -tvzf -

Slash → underscore for filenames (tag keys like `a/b:c` land as
`a_b:c`), tags with control chars or NUL are dropped from the
listing. Non-existent value blobs also drop.

Tag file inodes 1_000..9_999. Each getattr / read re-resolves
the tag key (they're mutable — a `pin --replace` under a tag
should show the new blob without unmount).

Reused alloc_blob_ino so tag reads share inodes with /blobs/<hex>
where possible. TagStore opened at `<data_dir>/tags-db` matching
the daemon's convention.

Omar Sobh 6f12bd908a Phase 6b: snapshots as directories in claw-fuse
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 18s
Details 
Extends the read-only FUSE mount with a `snapshots/` tree:

  <mount>/snapshots/<name>/               ← dir per snapshot
  <mount>/snapshots/<name>/<blob-id-hex>  ← file, content = assembled blob

Lets an operator browse a point-in-time capture by name — `ls`,
`find`, `sha256sum` all just work.

Implementation:
* Inode partitioning: 1 = /, 2 = /blobs, 3 = /snapshots,
  10_000..99_999 = snapshot dirs (lazy allocation), 100_000+
  = blob files (shared with the /blobs tree — same blob has
  the same inode whether reached via /blobs or /snapshots/<n>).
* lookup on /snapshots/<name> validates the snapshot exists via
  SnapshotStore::get.
* lookup on /snapshots/<name>/<blob-hex> validates both that
  the snapshot references that blob AND that the blob is on
  disk — no stale symlinks.
* Reused the shared alloc_blob_ino helper so the /blobs and
  /snapshots trees hand out identical inodes for the same blob.

No new tests: FUSE is integration-heavy and the underlying
snapshot + blob primitives are already covered.

Omar Sobh c678c08c76 Phase 6a: read-only FUSE mount over the blob store
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
First slice of Phase 6. Ships a minimal, feature-gated `claw-fuse`
binary that mounts the local blob store read-only as a POSIX
filesystem:

  <mount>/blobs/<blob-id-hex>   ← file, content = assembled blob
  <mount>/blobs/                ← dir, ls shows all blob-ids
  <mount>/                      ← dir, contains `blobs`

Lets an operator `tar -tvzf`, `md5sum`, or grep at a cached
tarball without wiring a client. Debug + audit tool for now;
warm-tier git-worktrees + write path come in later slices.

Feature-gated so my macOS dev box doesn't need macFUSE headers
to build the rest of the tree:
* Cargo.toml declares `[[bin]] name = "claw-fuse"` with
  `required-features = ["fuse"]`.
* Feature `fuse` pulls in `fuser = "0.15"`, target-restricted
  to `cfg(target_os = "linux")` — dep resolution never
  considers fuser on other platforms.
* `cargo build` (default) leaves claw-fuse out entirely.
  `cargo build --features fuse --bin claw-fuse` on Linux builds it.

Design notes baked into the impl:
* Inode allocation is lazy — first `lookup` for a hex assigns an
  inode. Avoids pre-indexing the full blob store at mount time
  which would be O(blobs) fs walk before FUSE is even ready.
* getattr / read validate that the manifest exists on every
  call — no stale-inode reads if a blob is GC'd out from under
  us mid-mount. Extra read cost is negligible against the
  per-request FUSE overhead.
* size = manifest.total_size (bytes reported without touching
  chunk files) so `ls -l` is cheap.
* runtime = current-thread tokio, block_on per callback. fuser
  is sync; a full tokio worker pool would just add scheduling
  overhead when callbacks are already serialized by the kernel.

No new tests here — Filesystem impls are integration-heavy and
the underlying BlobStore methods are already covered. The
`fuse` feature build itself will be smoke-tested on tank.

381 tests pass unchanged (feature-gated bin doesn't affect the
existing test surface).

Omar Sobh fa863fdc7d Phase 7e: claw-cargo smart-clean — 3 local cleanup modes
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
Reclaims local target-dir disk in increasing bluntness. All
modes are LOCAL only — the fleet blob cache is untouched, so
`claw-cargo build` after smart-clean restores from peer.

Modes:
* incremental-only — remove target/*/incremental/ across all
  profiles. Safest; keeps final artifacts + deps.
* soft (default) — remove target/ entirely. Blob still on peer.
* hard — soft, but requires --force. Reserved for operators who
  know their build is transient. Rejected without --force even
  in --dry-run so the safety belt can't be trained away.

--dry-run reports paths + byte count without touching disk.

New helpers (unit-tested in isolation):
* find_incremental_dirs(target) — walks target/*/incremental,
  returns only existing entries.
* dir_size_bytes(root) — recursive byte count, silent on read
  errors (used only for reporting, not correctness).

+5 tests: incremental discovery (existing only), missing target
empty, byte sum recursive, missing dir returns 0, hard-without-
force rejects.

381 tests pass (+5). Pre-existing macOS
hot::tests::test_project_target_size_bytes failure unchanged.

Omar Sobh dbc1587bcb Phase 8d: daemon binds a second QuicServer on the tailnet interface
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 11s
Details 
Live smoke on tank↔architect exposed the gap: bind_rpc_tailscale
was being *advertised* via gossip so peers learned to dial it,
but the daemon never actually LISTENED there. Tailnet dials hit
a closed port.

Fix: when both bind_rpc_lan and bind_rpc_tailscale are set (and
differ), spawn a second QuicServer on the tailnet address. Shares
the same fleet-CA identity + RpcRouter as the LAN listener —
requests from either side hit the same handlers.

If the second bind fails (e.g. tailnet interface not up), we log
a warning and keep the LAN listener alive rather than aborting
daemon startup. Standard graceful-degrade shape.

No new tests here — a live integration test would need two
network interfaces + a running tailscale, which the CI runners
don't have. Coverage happens on the tank+architect deployment:
`ss -lunp` on architect must show TWO clawstor UDP listeners
after this change (10.0.0.13:7702 + 100.104.171.32:7702).

Follow-on: cert SAN for the tailnet address. The current
fleet-CA-signed leaf only has the node name as SAN, so rustls
verification on the client side still checks against
--peer <name> which passes because CN == node name. But a
belt-and-suspenders leaf using fleet-ca-tailscale-sign (Phase
8a) would be more correct.

Omar Sobh f2c056464c Phase 8c hotfix: skip probe deadline when no fallback exists
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 2s
Details 
Live smoke on tank↔architect (both LAN) failed with 200ms probe:
LAN handshake takes longer than that in the wild (TLS 1.3 with
full cert chain + rustls startup on fresh endpoint). The old
single-addr .connect() had no deadline, so pre-8c callers never
noticed.

Fix: when `tailscale` is `None`, treat LAN as unlimited — the
probe deadline only matters as a fall-through trigger, and
there's nothing to fall through to. Callers with a real fallback
addr still get the fast-path routing behavior unchanged.

+1 test (connect_lan_first_lan_only_ignores_probe_deadline)
using a 1-nanosecond probe budget that a real handshake could
never meet — must succeed anyway because no fallback exists.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 11s
Details 
Wires the operator CLIs to the Phase 8b connect_lan_first primitive.
Roaming ops (laptop on LTE, coffee-shop wifi) can now pass a
tailnet address alongside the usual --rpc-addr and get the
LAN-first-with-fallback behavior automatically.

New flags on both cluster-peer-status and cluster-repair:
* --tailscale-addr <addr>   — optional tailnet RPC socket. When
                              set, --rpc-addr is tried first with
                              a short deadline, then this on
                              failure/timeout.
* --lan-probe-ms <ms>       — LAN probe deadline. Default 200
                              matches the arch doc.

Zero flag → byte-identical to pre-8c behavior (single-addr dial).
Both flags → chosen route printed in the output header so
operators can see whether LAN or tailnet won.

No new tests: this is thin glue over connect_lan_first, which
already has its own unit coverage. Smoke test live on tank
against architect (LAN), and against fake unroutable + real
tailnet exercises both branches.

Second Phase 8 slice. Prior transport.connect() took a single
address; the LAN-first-then-Tailscale routing the arch doc calls
out was implicit ("pick lan_addr OR tailscale_addr from gossip
state") and never actually raced or fell through.

New: QuicClient::connect_lan_first(name, lan, tailscale, lan_probe)
* Try LAN first with `lan_probe` deadline (fleet default ~200ms).
* If LAN handshake fails OR the deadline fires → fall back to
  the Tailscale address.
* Both slots None → error immediately (no hang).

Returns (connection, ConnectRoute) so callers + telemetry see
which side won. New enum ConnectRoute::{Lan(addr), Tailscale(addr)}.

+3 tests exercising the three shapes:
- lan-first when LAN reachable (never dials fake tailscale addr)
- fallback when LAN black-holes (240.0.0.1 SYN gets no response;
  probe deadline fires, tailscale server wins)
- errors cleanly when both addrs absent

- Wire the peer-connect call sites (RPC forwarding, PeerStatus,

  lan/tailscale addrs from gossip state.
- Document the roaming-client config template.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 25s
Details 
First slice of Phase 8 (roaming client identity). Adds a helper
that mints a leaf cert whose SANs include this node's Tailscale
identity — MagicDNS name (laptop.taila4f562.ts.net) + all tailnet
IPs — alongside the primary node name.

Closes the "how does a laptop join the fleet without hand-editing
SANs" gap: on a machine that's on Tailscale, one command produces
a leaf that peers can dial by MagicDNS from anywhere on the
tailnet.

New CLI:
  claw-store fleet-ca-tailscale-sign \
    --ca-dir /etc/claw-store/ca \
    [--node <name>]           # defaults to Tailscale HostName
    --out-dir /etc/claw-store/tls

Reads identity by shelling to `tailscale status --json` (already
present on any node that's on the tailnet; no extra dep). If
tailscale isn't running or installed, exits cleanly with a real
error.

New module cluster::tailscale:
* TailscaleSelf { magicdns_name, tailscale_ips, short_hostname }
* read_self() — runs the CLI, returns identity
* parse_status() — pure decoder, unit-tested
* suggested_sans() — MagicDNS + IPs ordered for the CA sign flow

FleetCa additions:
* sign_leaf_to_pem_with_sans(node_name, extra_sans, out_dir) —
  Sans-extended variant of sign_leaf_to_pem. Empty entries dropped.
  Existing sign_leaf_to_pem now delegates with empty extras (100%
  backward compat).
* mint_leaf_with_sans — internal shared helper.

+5 tests: parse full identity, parse missing MagicDNS, error on
no Self record, suggested_sans ordering, suggested_sans skips
missing MagicDNS.

372 tests pass (+5). Pre-existing macOS
hot::tests::test_project_target_size_bytes failure unchanged.

* dir doesn't exist or open() fails → logs warn, cache still valid.
* record() call fails → logs warn, cache still valid.

The tracking store is co-located with the daemon's data dir so
cluster-ref-sweep on that host sees the annotations. Runners
mount /var/lib/claw-store/data via bind-mount today.

No new tests here — the primitive (RefTracking::record) already
has full coverage. This is thin glue.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 6s
Details 
Wires the Phase 7f ref-tracking primitives to a real Gitea. New
CLI `claw-store cluster-ref-sweep --gitea-url <> [--gitea-token]
[--retention-days N]` queries every distinct repo we've recorded
against, fetches its live branches + tags, computes the stale set
via RefTracking::stale_at, and prints the stale fingerprints
grouped by repo.

Dry-run only in this cut. Deletion is separate — the operator
decides whether to call `forget` per fp, and whether to also
prune the corresponding blob/tag. Blob eviction happens via
cluster-gc as usual (dead refs no longer contribute to any pin).

New module cluster::gitea:
* GiteaClient::new(base_url, token) — reqwest with 15s timeout,
  rustls-tls (reuses the rustls stack quinn already pulls in).
* live_refs(repo) — fetches /branches + /tags concurrently,
  paginated (page 200 hard cap for safety), returns HashSet.
* 404 on either endpoint returns empty set — deleted repos then
  flow through stale_at as "all refs dead", the correct default.

Deps:
* reqwest 0.12 with rustls-tls + json, default-features off (no
  native-tls / openssl chain).
* clap 4 + "env" feature so --gitea-token can read GITEA_TOKEN.

Omar Sobh 294697d2f5 Phase 7f: ref-tracking primitives for retention-eligibility
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
Records which (repo, git-ref) combinations produced each cache
fingerprint. Later slices will wire this to a nightly Gitea sweep
that queries /api/v1/repos/.../branches and /tags, then evicts
fingerprints whose recorded refs are all gone AND whose
last_seen_unix is older than the retention window.

Per-fingerprint (not per-blob) because:
* Fingerprints are the cache keys claw-cargo uses. Tracking at the
  fp layer keeps this aligned with the claw-cargo boundary.
* Blobs are content-addressed and may be shared. Ref-tracking is
  about "why we kept this cache" — a per-fp concern.

New module cluster::ref_tracking:
* RefEntry { fingerprint, repo, refs, first_seen_unix, last_seen_unix }
* RefTracking::record(fp, repo, git_ref, now) — creates or updates
* RefTracking::get(fp) / list_all() / forget(fp)
* RefTracking::stale_at(now, live_refs_by_repo, retention_secs) →
  Vec<fingerprint>, the deletion-eligibility list

On-disk: <root>/ref-tracking/<hh>/<fp_hex>.json. JSON so operators
can inspect with jq. One record per cached fp; even 100k fps is
under 50 MB.

Semantics baked in:
* record() APPENDS refs, never removes — sweep decides staleness
* record() rejects repo change for a fp (collision or bug detector)
* refs stable-sorted in-file so cross-node diff is easy
* stale_at treats "repo not in live_refs map" as "all refs dead"
  → deleted repos don't leak caches
* retention_secs is a floor: dead-but-fresh caches survive

+10 tests: create, append-and-refresh, dedup, repo-change reject,
stale-at happy path, stale-at missing-repo, stale-at retention,
forget truth values, list sorted, validate rejects.

Omar Sobh eebc62d87b Phase 7d follow-on: snapshots pin blobs against LRU eviction
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
Closes the retention loop between snapshots and pin-aware LRU
eviction. A snapshot is not just a "list of blobs at time T" any
more — it's a *retention pin* on every blob it captures.
Operators can guarantee a build stays on disk for N days by
snapshotting it and pruning the snapshot when the window is up.

Additions:
* SnapshotStore::pinned_blob_ids() → union of blob_ids across all
  live snapshots. Cheap: one JSON read per snapshot.
* cmd_cluster_gc extends the tag-pin set with snapshot pins
  before handing it to evict_to_size_cap_with_pins. Output line
  now reads "pinned blobs: N (M from snapshots)".
* ClusterServices auto-GC ticker does the same on every tick;
  log fields include snapshot_pins so ops see the retention set
  size at a glance.

Omar Sobh e564b0ce89 Phase 7d: snapshot primitives + CLI
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
A snapshot is a named, immutable point-in-time record of every blob
live in the store. It's NOT a data copy — blobs are content-addressed
and already live under blobs/. A snapshot is a JSON reference set at
<root>/snapshots/<name>.json.

Why:
* Rollback anchor before risky migrations.
* Retention pin: combined with the Phase 4a pin-aware LRU eviction,
  operators can guarantee "these blobs stay on disk N days".
* Audit: "which blobs existed at release time?"

New module cluster::snapshot:
* SnapshotStore::create(name, blob_store, created_at)
* SnapshotStore::get(name) / list() / delete(name)
* SnapshotManifest { name, created_at_unix, blob_ids }
* SnapshotSummary for cheap list rendering (no blob-list slurp).

BlobStore gains list_blob_ids() — walks blobs/**/*.manifest.json
and returns the blob id set. Manifests only, no chunk reads.

New CLI commands:
* claw-store cluster-snapshot-create --name <>
* claw-store cluster-snapshot-list
* claw-store cluster-snapshot-show --name <>
* claw-store cluster-snapshot-delete --name <>

Semantics:
* Snapshots are immutable: create with existing name errors, does
  not clobber. Delete-then-create if you really want to overwrite.
* delete() removes only the reference file. Never touches blob
  data — protects against operators nuking live data by pruning
  snapshots.
* list() sorts by created_at_unix ascending — oldest first so
  triage picks pruning candidates quickly.
* blob_ids are sorted at write time so the same content on two
  nodes yields byte-identical snapshot files.
* Names validated: no /, \\, NUL, control chars; max 512 bytes.

Omar Sobh da198c0903 Phase 7c: cluster-repair CLI wires repair to a peer
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
New command: `claw-store cluster-repair --peer <name> --rpc-addr <host:port>
--tls-dir <dir> [--dry-run]`.

Flow:
1. Local scrub identifies bad chunks (missing + corrupt).
2. Deduplicate to unique chunk-hashes (scrub emits per-reference,
   fetcher work is per-chunk).
3. Connect to peer over QUIC + mTLS.
4. For each unique chunk: HasChunk probe → GetChunk on hit →
   put locally (re-hashed by put_chunk, so a lying peer can't
   corrupt us further).
5. Report attempted/repaired/unrecoverable/errors.

--dry-run stops after the dedup step: prints the plan without
touching the peer or disk.

Behavior details:
* Zero bad chunks → clean exit with no peer contact.
* Any unrecoverable or per-chunk error → non-zero exit so cron/CI
  notice. Message names counts.
* HasChunk-first means a peer that lacks the chunk is one cheap
  round-trip, not a full GetChunk attempt.

Companion piece for the Phase 7b repair library (already merged).
No new tests here — logic is thin glue over `repair_chunks` +
`call_has_chunk`/`call_get_chunk`, all of which have their own
unit + integration coverage. Behavior gets its real workout in
live smoke on tank+architect.

Omar Sobh cf0a07099d Phase 7b: chunk-level repair library
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Failing after 3s
Details 
New primitive: BlobStore::repair_chunks(chunks, fetch) → RepairReport.

Consumer flow: cluster-scrub returns a list of (blob, chunk) bad
pairs. cluster-repair (next slice) will hand the chunk hashes here
with a fetcher that walks peers via HasChunk/GetChunk. This PR is
the library-only half — no peer wiring — so it's testable in
isolation and reusable by callers who already have a chunk source.

Fetcher contract:
* Ok(Some(bytes)) → put locally, count repaired
* Ok(None)        → nobody has it, record as unrecoverable
* Err(e)          → per-chunk error, batch continues

Guardrails:
* Bytes are re-hashed by put_chunk before writing. A peer that
  returns wrong bytes for a hash cannot corrupt us further.
* Duplicate chunk hashes in the input dedupe → fetcher called
  exactly once per unique chunk. Matters because scrub reports
  shared chunks once per owning manifest.
* Errors on one chunk never abort the batch — the remaining
  chunks still get their shot.
* Repair overwrites a corrupt file: unlink-then-put_chunk, since
  put_chunk itself is write-if-absent. NotFound on unlink is fine
  (missing-chunk case).

+4 tests:
- repair_writes_fetched_bytes_and_marks_repaired (happy: corrupt
  → repair → post-scrub clean)
- repair_records_unrecoverable_when_fetcher_returns_none
- repair_records_error_and_continues_batch (batch survives one

Details 
New primitive: BlobStore::scrub_all() → ScrubReport.

Walks every .manifest.json under blobs/, for each referenced chunk
reads the file from disk and recomputes BLAKE3. Verdict per chunk:
* file absent → missing
* hash mismatch → corrupt
* match → ok

Design points:
* Read-only. Never touches disk state. Safe against a live daemon
  — worst case a chunk lands mid-scrub and is skipped this pass.
* Per-reference counting: a bad chunk that N manifests depend on
  shows up as N corrupt entries so operators see the full blast
  radius. But each unique chunk is hashed exactly once via an
  in-memory verdict cache.
* Report holds explicit (blob_id, chunk_hash) pairs for every
  bad chunk so the fix path (repair in Phase 7b) has enough
  info to act.

CLI: `claw-store cluster-scrub [--verbose]`. Non-zero exit when
integrity issues exist so cron / CI notice.

+4 tests:
- scrub_reports_all_ok_when_store_is_healthy

Details 
Wires cmd_pin through the WalQueue built in the preceding four
PRs (#48 → #52). First real caller of the client-mode WAL
stack.

New surfaces:

  claw-cargo pin --offline --blob <BlobId> [--ttl <duration>]
    * no peer connection is opened
    * enqueues the same three mutations cmd_pin would emit
      online: primary tag (PutTagVersioned), .fingerprint
      companion (PutTagVersioned), and — if --ttl — the two
      SetTagExpiry sidecars
    * requires --blob because offline mode can't do the
      GetRefVersioned lookup that resolves fingerprint → BlobId
    * prints the assigned WAL seqs + "next step: drain"

  claw-cargo drain --peer ...
    * opens a peer, drains the queue, truncates up to the last
      applied seq
    * partial-failure safe: whatever applied is truncated;
      anything after a hard error stays on disk for retry
    * exits non-zero when drain stopped mid-stream

  claw-cargo wal-status
    * read-only, no network
    * pending count, oldest/newest seq, storage path, decoded
      entries (or UNDECODABLE marker on frame errors)

WAL location follows the XDG state-home pattern already used
by manifest.rs:
  1. $XDG_STATE_HOME/claw-cargo/wal/
  2. $HOME/.local/state/claw-cargo/wal/
  3. ./.claw-cargo-wal/  (worst-case container fallback)

Tests (2): default_wal_path_honours_xdg_state_home (mirroring
manifest.rs's env-var pattern) + parse_blob_id_rejects_bad_
hex_and_wrong_len.

claw_cargo.rs grew from 1668 to ~1870 lines. Still under the
1300-per-*module* interpretation but this bin file has been
above 1300 since Phase 5. Split-out is Phase 6 territory.

Details 
Collapses the enqueue + drain + truncate dance around
WriteAheadLog + wal_mutation + wal_replay into one API so
downstream callers (Phase 4e: cmd_pin & friends) don't have
to orchestrate three modules themselves.

Two-call flow:

    let mut q = WalQueue::open(state_dir.join("wal")).await?;
    q.enqueue(&WalMutation::PutTagVersioned { .. }).await?;
    // ...later, on reconnect:
    let report = q.drain(&conn).await?;

drain() advances the watermark to the last successfully-
applied (or Superseded) seq whether or not the drive stopped
on a hard error mid-stream. Nothing is truncated past the
failure point, so the failing record and everything after
it are retried on the next drain.

Introspection surface (`pending_count` / `oldest_pending_seq`
/ `newest_pending_seq` / `snapshot` / `is_empty`) is what a
metrics endpoint or CLI status view wants. `wal()` escape
hatch exposes the backing WAL for advanced callers.

Tests (6, all green — 4 unit + 2 end-to-end over QUIC):
  * empty queue reports empty bounds
  * enqueue updates bounds correctly
  * snapshot decodes in seq order and preserves kind info
  * drain clears the queue and applies to peer (verifies via
    call_get_ref + call_get_tag_versioned)
  * drain over a pre-seeded dominant version returns
    Superseded and still drains the queue
  * enqueue survives reopen — bounds recover through
    WriteAheadLog::open scan

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
Given a peer connection + a decoded WalMutation, re-issue the
correct RPC. Closes the loop from "durably logged at client"
to "actually applied at peer" on reconnect.

Outcome classification is deliberate:
  * Applied    — peer accepted the mutation.
  * Superseded — peer already had a dominant version, or the
                 delete target was absent. NOT a failure; the
                 mutation's intent matches current peer state.
  * Err(_)     — genuine RPC failure; caller retries later.

Both Applied and Superseded advance the watermark past the
record — the WAL can safely truncate.

Public surface:
  ReplayOutcome { Applied | Superseded }
  replay_one(&conn, &mutation) -> Result<ReplayOutcome>
  drive_replay(&conn, &wal, start_seq) -> Result<DriveReport>
  DriveReport { last_applied, applied, superseded,
                skipped, stopped_at: Option<(seq, msg)> }

drive_replay stops on the first hard error and returns
last_applied so the caller can `wal.truncate_up_to(...)`
before closing. Undecodable/unknown-kind records mid-stream
are skipped (with warn!) rather than aborting — otherwise
one bad record would jam an otherwise-good tail forever.

Tests (4, all green, end-to-end over QUIC):
  * every variant round-trips; peer state verified via
    call_get_ref / call_get_tag_versioned / call_get_tag_expiry
  * versioned-reject counts as Superseded, not Err
  * DeleteTag on a missing key is Superseded
  * undecodable record between two real mutations is skipped;
    both good records still apply; last_applied advances past
    the skip

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
Adds the encoding layer that turns the raw WAL (opaque bytes)
into a typed queue of client-mode mutations, ready for Phase 4e
to wire actual RPCs through.

Frame (self-describing, forward-compatible):

  version : u8  = 0x01
  kind    : u8  = one of the Kind discriminants
  body    : [u8]  kind-specific

Body encodings mirror the existing on-wire shapes so a future
replay path can splice a WAL record straight into an RPC payload.

Variants (Kinds 0x01–0x06):
  PutRef, PutRefVersioned, PutTag, PutTagVersioned,
  DeleteTag, SetTagExpiry

Blob-put mutations are deliberately NOT modeled — blob data is
too large to keep in the WAL. The roaming-client design stages
blobs on local disk and records a reference to them once the
local BlobPutStream completes.

Public helpers:
  append_mutation(&mut wal, &m) -> Result<seq>
  replay_mutations(&wal, start_seq)
      -> Vec<(seq, Result<WalMutation, WalMutationError>)>

Unknown-kind records surface as `Err(UnknownKind(byte))`, not
a panic — forward-compat when a newer writer wrote a record
this reader doesn't understand. Malformed records also surface
as Err so the caller can decide (log-and-skip vs abort replay).

Tests (9, all green): kind-byte stability, roundtrip every
variant, rejects empty/short/bad-version/unknown-kind,
malformed bodies (wrong length, over-declared key_len, trailing
garbage on DeleteTag), non-UTF-8 keys, append+replay through a
real on-disk WAL, and replay-survives-unknown-kind mid-stream.

No new deps — hand-rolled error type in-tree (no thiserror).

Omar SobhandClaude Opus 4.7 0cf00e5954 Phase 4d: WAL segment rotation
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 17s
Details 
Turns the single-file Phase 4c WAL into a segmented log so it
can grow past a single file safely. This unblocks every
downstream Phase 4d/4e integration — reconnect + push loop
can't rely on an unbounded single file.

Layout change:
  <root>/segment-<20-digit-first-seq>.bin

20-digit zero-padded first-seq means lex sort == numeric sort,
so `read_dir + sort_by_key` recovers the natural order.

Rotation policy:
  * `max_segment_bytes` default 8 MiB, overridable via
    `open_with_options`.
  * `append` rolls to a fresh segment BEFORE writing when the
    current tail is non-empty AND at/above the cap. A single
    oversize record always lands in one segment — we never split
    a record.

Truncation across segments:
  * whole segments with `last_seq <= watermark` are `unlink`'d
  * the boundary segment (if any) is rewritten in place via
    `tempfile-in-parent + rename` + parent-dir fsync
  * full truncation resets head/tail to 0 and the next append
    creates a fresh segment

Legacy compat: on open, if a pre-4d `log.bin` is present and
no `segment-*.bin` files exist, it is scanned for its first
seq and renamed to the correct segment name. Refuses to
silently overwrite on filename collision.

Tests (18, all green): rotation-happens-at-cap, reopen-
enumerates-all-segments, truncate-drops-whole-segments,
truncate-partial-rewrites-boundary, oversize-record-still-
fits-one-segment, legacy-log.bin-migration, plus the full
Phase 4c suite (fresh open, append, iter partial ranges,
reopen recovers tail, torn-write truncation, corruption is
hard error, full truncation appendable, below-head no-op,
large payload, empty payload, append-after-reopen).

942-line file, comfortably under the 1300-line ceiling.

Foundation for the roaming/offline-client story described in
Architecture v2 ("Roaming client (full R/W, offline queue)"):
mutating ops append to a durable local log before hitting the
network, and are replayed at reconnect. This PR ships the
primitive; RPC/reconnect wiring lands in Phase 4d.

Segment format (single-file for now — rotation is 4d):

  seq   : u64 LE   (8 bytes)
  len   : u32 LE   (4 bytes)   payload length
  csum  : [u8; 8]  (8 bytes)   first 8 bytes of
                              BLAKE3(seq || len || payload)
  bytes : [u8; len]

On open, the log is scanned linearly. A short read or truncated
tail is treated as "clean crash boundary" — the file is
size-truncated to the last fully-fsynced record, no error.
A checksum mismatch on a full-length record is fatal (real
corruption, don't silently swallow data).

Public API:
  WriteAheadLog::open(root) -> Self
  wal.append(&[u8]) -> Result<u64>        // durable, fsynced
  wal.iter_from(start_seq) -> Vec<WalRecord>
  wal.truncate_up_to(watermark) -> ()     // atomic rewrite via
                                          // tempfile-in-parent + rename
  wal.head_seq() / wal.tail_seq() / wal.is_empty()

Tests (12, all green): fresh open, monotonic seq, replay full &
partial ranges, reopen-recovers-tail, torn-write truncation on
open, corruption is hard error, prefix truncation, full
truncation leaves appendable, below-head no-op, 1 MiB payload
roundtrip, empty payload roundtrip, append-after-reopen.

No new deps — BLAKE3 (already a dep) supplies the checksum.

Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
Closes Phase 4b by exposing the TTL sidecar written by
Phase 4b primitives on the wire and via `claw-cargo pin`.

Wire additions:
* Method::SetTagExpiry (0x1a) — payload `key_len:u16 || key ||
  expires_at:u64 (LE)`. Reply single-byte OK. `expires_at == 0`
  clears the sidecar.
* Method::GetTagExpiry (0x1b) — payload raw key bytes. Reply 8
  bytes (u64 LE) on hit; NotFound when no sidecar is present.

Both accept writes even when the stamped tag itself is absent,
matching `TagStore::set_stamped_expiry` semantics — the sidecar
takes effect the moment the tag lands.

CLI:
* `claw-cargo pin --ttl <duration>` — humantime-style duration
  (`30d`, `1h30m`, `2w`, ...). Applied to both the primary tag
  and its `.fingerprint` companion so eviction treats them as
  one lifetime. `--ttl 0` / `clear` / `none` clears an existing
  sidecar without touching the value.

Tests: encode/decode roundtrip + malformed-input rejection for
`encode_expiry_record`, method-byte stability, NotConfigured
without a tag store, end-to-end set/get/overwrite/clear over
QUIC, and a real-pin flow that publishes a stamped tag then
attaches TTL. Duration parser is unit-tested for single/compound
forms, case-insensitive units, bad input, and clock alignment.

No new deps — the humantime-style parser is 60 lines in-tree.

Omar Sobh 1418d35487 Phase 4b: TagStore expiry primitives (pin TTL groundwork)
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 16s
Details 
Adds the on-disk mechanism for time-scoped pins. No RPC or CLI yet
— a follow-on will expose \`pin --ttl <duration>\`. This PR is
purely library + eviction wiring.

Layout addition: alongside each stamped tag at
\`tags-v2/<hh>/<hash>.svtag\`, an optional sidecar
\`tags-v2/<hh>/<hash>.svtag.exp\` holds an 8-byte LE unix
\`expires_at\`. Absence of the sidecar = never expires (current
behavior).

New TagStore methods:
* set_stamped_expiry(key, expires_at_unix) — writes sidecar;
  passing 0 removes it. Idempotent.
* get_stamped_expiry(key) — reads sidecar; None when absent.
* pinned_blob_values_at(now_unix) — same union as
  pinned_blob_values, but skips stamped tags whose sidecar shows
  expires_at ≤ now. Legacy tags/ entries never expire.
* prune_expired_stamped_at(now_unix) — deletes stamped tags AND
  their sidecars where expires_at ≤ now. Returns count.
* pinned_blob_values() — now a shim that calls _at(u64::MAX) for
  100% backward compat.

Wired the two existing gc call sites:
* ClusterServices auto-GC ticker prunes-then-collects at
  SystemTime::now(). One pass per tick.
* \`claw-store cluster-gc --evict-to-gb N\` CLI same pattern.
  Report now includes \"expired pins pruned: N\".

+1 test (expiry_gates_pin_set_and_prune_removes_expired):
  covers live/expired/no-ttl mix, sidecar round-trip, prune
  removes only expired, expires_at=0 clears sidecar, dropped
  tag stops filtering.

286 tests pass (+3 from 283). Pre-existing macOS
hot::tests::test_project_target_size_bytes failure unchanged.

Omar Sobh 5be11a11b0 Phase 4a: pin-aware LRU eviction
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
A `claw-cargo pin` used to be silently vulnerable to the size-cap
eviction ticker — the tag existed but the underlying blob could get
LRU'd out, leaving a dangling reference. Now tags act as
retention markers: any blob referenced by any tag (stamped or
legacy) is protected from `evict_to_size_cap`.

* `BlobStore::evict_to_size_cap_with_pins(max_bytes, pinned_set)` —
  same LRU-by-mtime pass, but pinned blob IDs skip the eviction
  loop. Existing `evict_to_size_cap` is now a thin wrapper with an
  empty pin set (100% backward compat).
* `TagStore::pinned_blob_values()` — unions every 32-byte value
  referenced by any tag across `tags/` (legacy) and `tags-v2/`
  (Phase 3c stamped). Dedupes naturally.
* Auto-GC ticker in `ClusterServices` now collects the pin set on
  every eviction pass and passes it in. Log fields include
  `pinned_blobs = N` so operators can see the retention set size.
* `claw-store cluster-gc --evict-to-gb N` CLI opens the tag store
  the same way, prints `pinned blobs: N` in the report.

+3 tests:
- evict_with_pins_protects_pinned_blobs_from_eviction — 3 blobs
  ordered oldest→newest, pin the oldest; without pins LRU would
  evict it; with pins the next-oldest goes instead. Guards the
  main semantic.
- evict_with_pins_stops_when_pinned_footprint_dominates —
  everything pinned + cap = 0 → no-op. Guards the "operator asked
  for the impossible" case.
- pinned_blob_values_unions_both_stores — legacy tag with value V1,
  stamped tag with value V2, second stamped tag also referencing
  V1 → set contains {V1, V2}. Dedupe check.

283 tests pass (baseline +3). Pre-existing macOS failure unchanged.

Omar Sobh 2c3cd2ab38 Phase 3c + 3e: stamped tags + namespaced ref keys — closes Phase 3
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 20s
Details 
Ships the last two pieces from the arch doc's Phase 3 scope for the
cargo-cache use case:

## 3c: Stamped tags (CRDT-merge on PutTag)

Mirror of Phase 3a/3b for TagStore. Two concurrent `claw-cargo pin`
calls on the same tag now race deterministically instead of silently
clobbering.

* `StampedTagValue` — same 48-byte (value, clock, node) tuple as
  StampedRef.
* `TagStore::put_stamped(key, StampedTagValue) -> TagPutOutcome`
  and `TagStore::get_stamped(key)` — data lives under `tags-v2/`
  (separate from `tags/` for cutover safety).
* New wire methods `PutTagVersioned = 0x18` +
  `GetTagVersioned = 0x19`.
* `call_put_tag_versioned` / `call_get_tag_versioned` client
  helpers.
* `claw-cargo pin` now writes stamped tags. Concurrent pin gets
  AlreadyExists and moves on (blob content is content-addressed so
  both winners agree on the payload).

## 3e: Namespaced ref keys

Opt-in `--namespace <slug>` on peer-facing subcommands. When set,
the ref key becomes `blake3("clawstor.ns.v1" || namespace || fp)`
so two runners on different namespaces (`clawverse/main` vs
`clawverse/pr-42`) don't collide on the same fingerprint. Empty
namespace = pre-3e behavior, so this is 100% backward compat.

* `refs::namespaced_ref_key(namespace, fingerprint) -> RefKey`
  primitive.
* `PeerArgs::namespace: Option<String>` CLI flag flows through to
  `cmd_status`, `cmd_prefetch`, `cmd_build`.
* `peer_lookup` now takes a `RefKey` directly (was `&Fingerprint`)
  so the namespace resolution stays in the caller — the daemon
  never sees "namespace" as a concept.

## 3d: Deferred

Full vector clocks per namespace are noted in the arch doc as a
Phase-3 goal; scalar wall-clock (clock + node stamp) is sufficient
for the cargo-cache use case (single-key LWW merge). NTP-synced
runners see monotonic ordering; skewed runners lose an ordering
but the CRDT semantics still guarantee no data corruption. Full VC
is deferred to a future phase.

Omar Sobh 58c5bc341b GetRef: transparent ref-forwarding on local miss
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
Cross-runner cache silos (tank + architect measured on 2026-07-13):
same fingerprint, same rustc, but each runner's daemon only knows
about the refs its own runner uploaded. Every runner that lands on
a peer that isn't tank re-uploads a duplicate blob.

Fix: on `GetRef` miss the daemon fans out to alive gossip peers
via a strict-local `GetRefLocal` variant, and the FIRST peer that
has the ref triggers a transparent pull — chunks + manifest into
the local blob store, then `PutRef` locally — before returning the
value to the caller. Subsequent lookups are pure-local hits.

* `Method::GetRefLocal = 0x14` — new wire method, identical shape
  to GetRef but the peer MUST NOT recurse. Loop prevention: our
  forwarding only calls `GetRefLocal` on peers, so chain depth is
  always 1.
* `RpcRouter::with_outbound_client(Arc<QuicClient>)` — dependency
  injection point for the forwarding dial path. `None` disables
  forwarding entirely (GetRef becomes GetRefLocal-equivalent).
* `RpcRouter::forward_get_ref(key)` — concurrent peer probes via
  `JoinSet`, 3s timeout per dial, first successful pull wins,
  remaining tasks aborted.
* `pull_blob_locally` — walks manifest, fetches only chunks the
  local store lacks (`has_chunk`), commits via
  `put_manifest_verified`. Bounded memory: one 4 MiB chunk at a
  time.
* `ClusterServices::start` loads NodeIdentity twice — server takes
  ownership; outbound client gets its own copy for TLS presentation
  on peer dials. Wires the outbound client into the router when
  TLS material is available.
* `call_get_ref_local(conn, key)` client helper (used by daemon
  forwarding + available to any RPC consumer that wants the
  no-recursion semantics).

+3 tests in `rpc/tests_forwarding.rs`:
- Local hit works without forwarding; local miss with no peers
  returns None. Guards the base cases.
- GetRefLocal never forwards even when outbound is configured (no
  peers reachable → miss returns None immediately, no attempted
  fan-out).
- Method byte 0x14 encoding is stable across releases.

Full end-to-end forwarding is exercised in the pilot deploy: two
daemons on the fleet-CA, tank populates a ref, architect's runner
GetRef → tank forwards → architect pulls → HIT locally next time.

264 tests pass (baseline +3). Pre-existing macOS failure unchanged.

Omar Sobh bfcc11de82 runner follow-ups: XDG config path + composite action + docs
Build with clawstor cache / Cargo build (clawstor-cached) (pull_request) Successful in 10s
Details 
Three fixes surfaced by the 2026-07-13 Gitea Actions wire-up.

## XDG config path

Before: `client_config::user_config_path` only looked at
`~/.claw-cargo/config.toml`. My runner-integration doc initially
told operators to install at `~/.config/claw-cargo/config.toml`
(XDG-style). Config wasn't loaded.

Now: three-way lookup, first hit wins.
  1. `$XDG_CONFIG_HOME/claw-cargo/config.toml`
  2. `$HOME/.config/claw-cargo/config.toml`
  3. `$HOME/.claw-cargo/config.toml` (legacy, still honoured)

+3 tests: XDG env wins when the file exists, .config wins over
legacy dotfile when both present, legacy dotfile returned as
error-message fallback when none exist.

## Composite action

Before: composite action silently no-op'd. Log showed the script
lines echoed but only the `if command -v claw-cargo` fail branch
ran. Root cause: Gitea Actions composite steps run with a stripped
PATH that omits `/usr/local/bin`.

Now: composite step exports PATH defensively:

    export PATH="/usr/local/bin:$HOME/.cargo/bin:$PATH"

And it looks for the config at BOTH the XDG-style path and the
legacy dotfile (same order as client_config).

Workflow file back to using the composite action.

## Docs

Runner-integration doc now:
- Explicitly warns that `ubuntu-latest` routes to container mode
  even with `:host` suffix on runner labels (field-observed).
- Documents the dedicated `clawstor-cache` label pattern that
  works.
- Sample workflow uses `runs-on: clawstor-cache` instead of
  `ubuntu-latest`.

+3 tests, 262 total (baseline unchanged).

  elapsed-seconds. Runner-side config lives in
  `~/.config/claw-cargo/config.toml` (not in the workflow — no
  secrets shipped from repos).
* `.gitea/workflows/build-with-cache.yml` — dogfoods the action on
  clawstor's own repo. `no-upload` set from event_name so PRs from
  forks can't poison the cache.
* `docs/runner-integration.md` — one-time setup steps, sample
  workflow snippet, expected numbers (Pi 5: 2.79× wall, tank:
  2.18×), and troubleshooting for the failures I hit in the tank
  and Pi pilots (bind_lan on fabric-only, missing CLI/config,
  rustc drift warn).

Test protocol: push this branch → main triggers the workflow → the
runner on tank has claw-cargo + tls + config provisioned already
(2026-07-13 pilot setup) → first build should MISS + populate,
subsequent build on same fingerprint should HIT.

Omar Sobh 1053930451 claw-cargo: default --parallel-restore back to 1 (sequential) 
Pi 5 loopback measurement 2026-07-13:

  --parallel-restore 1 : wall 2m52s, restore 20s
  --parallel-restore 8 : wall 3m06s, restore 34s

Sequential is 70% faster on loopback. N-way stream contention costs
more than a single stream's congestion-control amortization. Same
shape as Phase 5k prewarm — fanout only wins when per-stream
throughput has a ceiling (WAN, tunneled links).

--parallel-restore N remains as opt-in.

Omar Sobh 846ecffe10 Pi deploy follow-ups: XDG default_path + parallel restore 
Two fixes surfaced by the vision-02 Pi 5 measurement:

## XDG default_path

`Manifest::default_path` was hardcoded to
`/var/lib/claw-store/projects.toml`. That path is read-only under
the user-mode systemd unit's `ProtectSystem=strict`, and creating
it needs root — awful for a runner install.

Precedence, matching XDG Base Directory:
  1. `$XDG_STATE_HOME/claw-store/projects.toml`
  2. `$HOME/.local/state/claw-store/projects.toml`
  3. `/var/lib/claw-store/projects.toml` (system fallback)

User-mode installs now write in $HOME by default; system installs
(root, no HOME set) still land in /var/lib.

+1 test: `default_path_honours_xdg_state_home` — covers all three
precedence branches. Env mutation is process-global so the test
saves + restores.

## Parallel restore on cache HIT

Pi restore of 947 MiB via `BlobGetStream` took ~18s (~53 MiB/s)
single-stream. Per-stream throughput ceilings on the connection
type cap sequential fetches; parallel chunk fetches stack their
contributions.

- New `call_blob_get_parallel(conn, blob_id, concurrency) ->
  Option<Vec<u8>>` in `rpc/client.rs`. `JoinSet` + `Semaphore`,
  reassembles by chunk index at manifest-known offsets so
  out-of-order arrival is fine.
- `claw-cargo build --parallel-restore N` (default 8). `N <= 1`
  falls through to `BlobGetStream` for parity.
- Memory: `total_size + 4 MiB × in-flight` — dominated by the
  reassembly buffer, not the fanout.

+1 test: `parallel_blob_get_reassembles_multi_chunk_blob_byte_equal`
covers roundtrip byte-equality vs BlobGetStream, tail-chunk offset,
concurrency=1 correctness, and NotFound → None.

259 tests pass (+2). Pre-existing macOS failure unchanged.

Omar Sobh 2f3055a3aa blob: size-based LRU eviction + auto-cap in the GC ticker 
Orphan-chunk GC alone doesn't stop unbounded growth: as long as
fingerprint→blob refs keep getting PutRef'd, the manifest set keeps
growing and no chunk is ever an orphan.

* `BlobStore::evict_to_size_cap(max_bytes)` — walks manifests oldest
  first by mtime, deletes them, refcount-decrements each chunk they
  used, unlinks + reclaims size for any chunk whose refcount hits
  zero. Shared chunks stay put until the last blob referencing them
  is evicted.
* `ManifestSummary` internal type keeps the diff-set bookkeeping
  cheap (one HashMap<ChunkHash, u32>, no repeated tree walks).
* `claw-store cluster-gc --evict-to-gb <N>` extends the CLI: still
  runs the orphan sweep first, then optionally caps the store.
* Config: `cluster.blob_max_gb: Option<u64>`. The auto-GC ticker
  runs eviction after every orphan sweep when this is set. Silent
  when the store is already under cap; INFO log when it evicts.

+3 tests:
- evict_to_size_cap_reclaims_oldest_blobs_first: 3 blobs with
  distinct mtimes, cap below combined size → oldest evicted,
  newer blobs survive
- evict_keeps_shared_chunks_when_still_referenced: guards the
  refcount decrement path (content-addressed dedup keeps identical
  content as one blob → chunk survives until manifest deleted)
- evict_on_empty_store_is_a_noop: sanity

257 tests pass (baseline +3). Pre-existing macOS failure unchanged.

Omar Sobh 84aa758fd4 Two pilot follow-ons: rustc drift warning + blob GC 
Both surfaced by the 2026-07-12 pilot as real operator concerns:

## rustc drift warning at build time

Runners silently silo their cache when rustc versions differ across
peers (fingerprint depends on rustc verbose output). The pilot's
first flow burned a full cold+upload before we realized the silo.

- `PeerStatusReply.local_rustc_release` — new field, populated from
  the peer's own gossip `RUSTC_RELEASE` key via a new
  `ClusterGossip::self_kv(key)` accessor.
- `claw-cargo build`: on cache MISS, calls `PeerStatus`; if the
  peer's rustc release ≠ our local `rustc --version`, emits a WARN
  with both versions + hint to add `rust-toolchain.toml`.
- Best-effort: absence of either release string is a shrug, not
  an error.

## blob GC

Blob store grows unbounded on a runner; disk-full is a real
incident. `gc_orphan_chunks` already existed but wasn't exposed.

- New CLI: `claw-store cluster-gc` — runs `gc_orphan_chunks`,
  prints report. Safe to run any time, safe to interrupt.
- New config: `cluster.gc_interval_hours: Option<u64>`. When set to
  a positive integer, the daemon spawns a periodic ticker that
  invokes GC in-process. Skips the first tick (nothing to reclaim
  on boot). Errors are logged and retried next tick.
- Shutdown aborts the ticker cleanly.

254 tests pass (baseline unchanged). Pre-existing macOS failure
untouched.

Omar Sobh 54e9da4d62 Phase 5k: parallel-fanout chunk transfer for prewarm 
Pilot 2026-07-12 measured 109 MiB/s on the sequential prewarm path —
~11% of a 10G fabric. `quinn::Connection` is cheap-Clone (internal
Arc), so we can run the has→get→put pipeline per chunk in concurrent
tasks under a bounded semaphore.

- `prewarm_missing_chunks_between_parallel(up, down, id, concurrency)`
  in `rpc/client.rs`. `concurrency <= 1` degrades to the sequential
  path (kept for diagnostic parity).
- `claw-cargo prewarm --parallel N` (default 8). Ignored with
  `--buffered`. Memory ceiling: 4 MiB × in-flight = 32 MiB @ 8,
  128 MiB @ 32.
- Uses `tokio::task::JoinSet` + `Arc<Semaphore>`; permit held for
  the whole per-chunk pipeline so we never over-commit.
- Retry pass on `put_manifest` mismatch stays sequential — small,
  correctness-critical.
- Errors: JoinSet drains completely + returns first task error so a
  mid-fanout failure doesn't leave zombie tasks.

+1 test: `end_to_end_parallel_prewarm_copies_chunks_and_matches_sequential`
runs 5-chunk payload with concurrency=3, verifies byte-equal restore,
then reruns with concurrency=8 → 0 uploads (has_chunk dedup), then
concurrency=0 → 0 uploads (sequential fallback path).

254 tests pass (+1 from previous). Pre-existing macOS failure unchanged.

Omar Sobh 264ee81189 systemd: cluster daemon unit for production lifecycle 
Pilot ran the cluster daemon under nohup; production needs proper
restart-on-failure + clean PATH inheritance (rustc gossip probe
needs `~/.cargo/bin` on PATH, which nohup's env didn't get).

The unit is user-scoped (`~/.config/systemd/user/`) so it works
without root on the pilot nodes:

  cp systemd/clawstor-cluster.service ~/.config/systemd/user/
  loginctl enable-linger $USER
  systemctl --user daemon-reload
  systemctl --user enable --now clawstor-cluster.service

Defaults:
- CLAWSTOR_BIN = ~/clawstor-deploy/claw-store
- CLAWSTOR_CONFIG = ~/clawstor-deploy/config.toml
- PATH prefixed with ~/.cargo/bin so rustc is found

Override any of those via `systemctl --user edit
clawstor-cluster.service`.

Security hardening:
- NoNewPrivileges=yes
- ProtectSystem=strict (system dirs read-only)
- ProtectHome=read-only (home dir read-only)
- ReadWritePaths=%h/clawstor-deploy (only the deploy tree is
  writable)
- PrivateTmp=yes

Restart semantics:
- Restart=on-failure with RestartSec=10 — pilot-verified: kill -9
  the daemon PID and the service comes back within ~10s
- TimeoutStopSec=60 so a slow gossip departure can complete

Deployed to tank + architect 2026-07-12 as part of the pilot
retest.

Omar Sobh cb07bfc574 capture: stream to a Writer instead of buffering the whole tar in RAM 
Field finding 2026-07-12 (clawverse measurement): the buffered
`capture_target -> Vec<u8>` path peaked at 2.8 GB RAM to capture a
6.1 GB target/debug into a 995 MiB compressed tar. Every byte
crossed RAM before touching the network.

* `capture_target_to_writer(target_dir, writer) -> u64` — new
  streaming variant. Walks the tree + writes tar+zstd straight into
  the caller's Writer via a small ByteCounter wrapper. Peak memory
  stays at ~zstd sliding window size (few MB).
* `capture_target -> Vec<u8>` kept as a thin wrapper for the tests
  + smaller callers that don't care.
* `cmd_build`: capture into a tempfile under `target/`, then open
  it with `tokio::fs::File` (AsyncRead + Unpin) and hand that to
  `call_blob_put_stream`. Same-filesystem tempfile means no cross-
  mount concerns; auto-unlinks on drop.

+1 test: `capture_streaming_matches_buffered_and_restores_correctly`
proves the streamed bytes match the buffered variant, the reported
byte count agrees with the written length, and roundtrip restore
from the streamed file works.

Combined with PR #22 (QUIC idle timeout), this closes the two RAM/
timeout blockers surfaced by the clawverse pilot. Expected memory
ceiling on a runner drops from GBs to MBs, unlocking small-runner
deployments (the actual pitch use case).
 2026-07-12 06:02:55 -07:00
Omar Sobh c08f60a2aa transport: bump QUIC idle timeout + add keep-alive for long builds 
Field finding 2026-07-12 (clawverse cold on tank):

    Compiling claw-cli v0.1.0 (...)
    Finished `dev` profile ... in 45.08s
    cargo build finished in 45.135491979s
    Error: opening bidi stream for BlobPutStream
    Caused by: timed out

Cargo took 45s → QUIC's 30s idle timeout killed the connection between
the initial peer-lookup connect and the follow-up capture+upload path.
The RPC never got a chance to open its stream.

Fix: two belt-and-braces changes:
1. IDLE_TIMEOUT 30s → 600s. The timeout is there to detect crashed
   peers, not to enforce build pacing.
2. Client applies a `keep_alive_interval` of 15s so the connection
   stays warm across cargo runs even shorter than the idle window.

quinn's keep-alive fires from an internal runtime task, not the app
thread, so a fully-CPU-pinned cargo build doesn't suppress it.

Omar Sobh e70f5d74e0 Pilot findings: 5 real-world fixes from the 2026-07-12 deploy 
Bundles the profile→dir bug (PR #20 supersede) with four new fixes
discovered by running clawstor against itself + across the fabric:

* target_subdir_for: `dev`/`test` → `debug/`, `release`/`bench` →
  `release/`, custom passes through. Was silently skipping upload.

* rustc release via gossip: daemon probes `rustc --version` at start,
  publishes the release string as `clawstor.rustc.release`. PeerView
  carries it; `cluster-peer-status` prints it in a new column and
  emits a warning line when the fleet has mixed versions. Would have
  surfaced the tank/architect 1.96.1 vs 1.95.0 drift instantly.

* prewarm publishes fingerprint→blob ref downstream: `pin` now writes
  a companion tag `<name>.fingerprint` holding the fingerprint bytes.
  `prewarm` reads the companion, PutTag's it downstream, then
  PutRef(fp→blob) so a subsequent fingerprint-based `build` HITS.
  Without this, prewarm was almost useless for the runner path
  (build always missed even with matching source + rustc).

* streaming byte counters: BlobPutStream + BlobGetStream now record
  the transferred bytes via `record_blob_{put,get}_bytes`. Metric
  used to stay at 0 no matter how much you moved.

* capture determinism: replaced `tar::Builder::append_dir_all` (uses
  `read_dir`'s native order) with `append_dir_sorted` that walks the
  tree recursively and sorts by filename bytes at every level. Two
  byte-identical trees now produce byte-identical tars regardless of
  filesystem ordering.

+3 tests:
- target_subdir_matches_cargo_layout (from #20)
- fingerprint_companion_tag_uses_dotted_suffix
- capture_is_order_independent_of_filesystem_readdir (guard against
  the exact bug we saw in the field)

252 tests pass (+1 from Phase 5h's 251). Pre-existing macOS `du -sb`
failure unchanged.

Supersedes #20 (also included here). Ready for re-deploy to
tank + architect for the retest run.

# clawstor # clawstor
ZFS-backed fleet storage daemon for the clawverse two-node cluster (architect + tank). Manages a three-tier hot/warm/cold storage model with automatic GC, hourly/daily/weekly ZFS snapshots, incremental cold replication, and a live SSE dashboard. Rust-native distributed storage + fingerprint-keyed cargo build cache for
small trusted fleets. Content-addressed blobs over QUIC+mTLS, gossip
membership, CRDT-merged metadata, FUSE mount, and a claw-cargo wrapper that
turns any peer with the cache into a build accelerator.
**Source:** <https://git.redclaw.dev/clawverse/clawstor>
--- ---
## Architecture ## What you get
``` **Distributed content-addressed storage**
Hot tier /hot/targets/<org>/<repo>/ NVMe — active Cargo target dirs - BLAKE3-hashed blobs, chunk-level dedup (1 MiB chunks).
Warm tier /slab/projects/<org>/<repo> ZFS dataset — canonical git repos - Every peer-to-peer transfer QUIC 0-RTT + mutual TLS 1.3 against a fleet CA.
Cold tier /data/archive/ Nightly incremental ZFS snapshot send - LAN-first probe with tailnet fallback — roaming laptops keep working from anywhere.
``` - Same-fingerprint = same bytes anywhere in the fleet: never re-upload the same cache.
**Hot (NVMe):** `cargo build` target directories symlinked into the NVMe partition. Activated on demand; GC'd when stale or when the hot tier exceeds `max_gb`. **Fingerprint-keyed cargo cache**
- `claw-cargo build` = drop-in `cargo build` with a peer-cache lookup wrapper.
- Fingerprint = deterministic function of `Cargo.lock` + `Cargo.toml` + rustc release + profile + features.
- HIT: download + restore `target/` in seconds. MISS: build + capture + upload.
- Streaming chunk transfer with `--parallel-restore N` for cross-node WAN links.
**Warm (ZFS):** The working checkout of every project, on a ZFS dataset that receives hourly, daily, and weekly snapshots. This is the source of truth for all git history. **Human-friendly primitives**
- **Pins / tags** — `claw-cargo pin --name clawverse:main:latest-cache`. Human handle for a specific blob. Auto-annotates git ref via `--repo` + `--git-ref`.
- **Snapshots** — `cluster-snapshot-create --name release-2026-07`. Immutable named record of every blob live at capture time. Blobs referenced by any snapshot survive LRU eviction automatically.
- **Ref-tracking** — every cache-put records `(repo, git-ref)`. Nightly Gitea sweep finds fingerprints whose refs are gone → deletion candidates.
- **Read-only FUSE mount** — `~/clawstor-mount/{blobs,snapshots,tags,refs}/*` — any POSIX tool sees the whole store.
**Cold (ZFS send):** Tank sends incremental ZFS snapshots to architect nightly over the 10G fabric link (`10.10.0.9 = architect-fab-tank`). The first run is a full send; subsequent runs are incremental (`zfs send -i <prev>`). **Operations**
- **Scrub** — read-only BLAKE3 fsck (weekly).
- **Repair** — peer-pull missing/corrupt chunks with hash re-verify.
- **GC** — orphan-chunk sweep + pin-aware LRU eviction (nightly).
- **Snapshot rotation** — `daily-YYYY-MM-DD` create + 30-day retention (daily).
- All ordered via systemd user timers; log to journalctl.
**Roaming clients (Phase 8)**
- `fleet-ca-tailscale-sign` — mint a leaf cert whose SANs include this node's Tailscale MagicDNS + tailnet IPs. Zero-touch bootstrap for laptops.
- Daemon dual-binds on LAN + tailnet interfaces. Advertised via gossip.
- `--tailscale-addr` on peer-status / repair / ping CLIs enables fallback routing.
**Reliability shape**
- Write-ahead log (Phase 4): `pin --offline` queues mutations; `drain` replays on reconnect.
- CRDT-merged refs + tags (Lamport `(clock, node)` total order) — concurrent writes are conflict-free.
- Non-zero-exit on integrity failures — timers surface via systemd `failed` state.
--- ---
## Nodes ## Architecture (one paragraph)
| Node | Role | IP (LAN) | ZFS pool | Each node runs `claw-store daemon`. Daemons find each other via `chitchat`
|---|---|---|---| SWIM gossip. Content flows over `quinn` (QUIC/TLS 1.3) with mutual auth
| architect | primary | 10.0.0.13 | `slab` | against a fleet CA. Blobs are chunked into content-addressed pieces
| tank | secondary | 10.0.0.14 | `slab` | under `<blob_root>/chunks/<hh>/<hex>` and stitched via
`blobs/<hh>/<blob_id>.manifest.json`. Named handles (tags, refs, snapshots,
ref-tracking annotations) live in sibling directories. Everything under
`<blob_root>` is safely rsync'd — content addressing means restore-from-tar
never corrupts the store.
Architect holds the cold archive. Tank sends to architect. The 10G fabric IP (`10.10.0.9`) is used intentionally for replication bandwidth. Full design: [`ARCHITECTURE-v2.md`](ARCHITECTURE-v2.md).

## Fleet layout (reference)
Current production deployment — 3 nodes, all identical:
| Node | Zone | State |
|---|---|---|
| tank | fabric-10g | daemon + FUSE + 4 timers |
| architect | fabric-10g | daemon + FUSE + 4 timers |
| morpheus | lan-1g | daemon + FUSE + 4 timers |
Consistency snapshot: `deploy/scripts/fleet-status.sh`.

## Install ## Install
### Prerequisites ### Prereqs (Linux)
- Rust toolchain (`rustup`) ```bash
- Node.js + npm (for dashboard build) # For the daemon + claw-cargo (release build)
- ZFS installed and pools imported rustup default stable
- SSH key from tank → architect configured (see [SSH setup](#ssh-setup))
### Build and install # For the FUSE mount only
sudo apt install libfuse3-dev pkg-config
```sh
# On architect
sudo make deploy NODE=architect
# On tank
sudo make deploy NODE=tank
``` ```
This runs `cargo build --release`, copies the binary to `/usr/local/bin/claw-store`, builds and installs the React dashboard to `/usr/share/claw-store/static`, installs systemd units, and enables all services and timers. ### Build
### Makefile targets ```bash
git clone https://git.redclaw.dev/clawverse/clawstor
cd clawstor
| Target | What it does | # Daemon + CLI wrapper — always available.
|---|---| cargo build --release --bin claw-store --bin claw-cargo
| `make build` | Compile release binary |
| `make install` | Install binary to `/usr/local/bin` |
| `make install-systemd` | Install and reload all systemd units |
| `make install-dashboard` | Build React dashboard and copy to `/usr/share/claw-store/static` |
| `make install-config NODE=architect` | Install node-specific config |
| `make deploy NODE=architect` | Full install + enable all units |
| `make uninstall` | Remove binary and systemd units (preserves config and data) |
| `make clean` | Remove build artifacts |
--- # FUSE mount — feature-gated.
cargo build --release --features fuse --bin claw-fuse
```
## Configuration Binaries land at `target/release/{claw-store,claw-cargo,claw-fuse}`.
Config files live in `config/`. Install the right one with `make install-config NODE=<node>` which copies it to `/etc/claw-store/config.toml`. ### First-time cluster bootstrap (once, on the primary)
### Key options ```bash
# Mint the fleet CA. Keep ca.key on this box only.
claw-store fleet-ca-init --dir /etc/claw-store/ca --cn "clawstor fleet CA"
# Sign a leaf for this node.
claw-store fleet-ca-sign \
--ca-dir /etc/claw-store/ca \
--node tank \
--out-dir /etc/claw-store/tls
# For a Tailscale-attached roaming node, use the tailscale-aware variant
# so the leaf's SANs include the MagicDNS name + tailnet IPs.
claw-store fleet-ca-tailscale-sign \
--ca-dir /etc/claw-store/ca \
--out-dir /etc/claw-store/tls
```
For any additional peer: repeat `fleet-ca-sign --node <name>` on the primary
and copy the three PEMs (`ca.crt`, `node.crt`, `node.key`) to that peer.
`node.key` is `chmod 600` — distribute via secure channel.
### Config template
`/etc/claw-store/config.toml`:
```toml ```toml
[node] [node]
name = "architect" name = "tank"
role = "primary" # primary | secondary role = "primary" # primary | secondary

node_key = "/etc/claw-store/tls/node.key"
# Optional — require Bearer token on all HTTP POST endpoints
# api_token = "your-long-random-token-here"
``` ```
To enable API authentication: ### Systemd (Linux)
```toml User-scoped units live under `deploy/systemd/`. Install pattern:
api_token = "$(openssl rand -hex 32)"
```bash
mkdir -p ~/.config/systemd/user
cp deploy/systemd/*.service deploy/systemd/*.timer ~/.config/systemd/user/
systemctl --user daemon-reload
# Always-on: daemon + FUSE mount.
mkdir -p ~/clawstor-mount # required — the unit no longer mkdir's it
systemctl --user enable --now clawstor-cluster.service clawstor-fuse.service
# Scheduled ops (all four).
systemctl --user enable --now clawstor-snapshot-rotate.timer \
clawstor-ref-sweep.timer clawstor-gc.timer clawstor-scrub.timer
``` ```
All `GET` requests (dashboard, status, project list) are always allowed. `POST` requests (activate, deactivate, gc, sync, snapshot) require `Authorization: Bearer <token>`. Full details + drop-in override examples: [`deploy/systemd/README.md`](deploy/systemd/README.md).
### macOS (ghost, macbook)
macFUSE prereq (one-time, requires admin approval + reboot):
```bash
brew install --cask macfuse
brew install pkg-config
# Reboot, click through System Settings → Privacy & Security → Allow.
cargo build --release --features fuse --bin claw-fuse
```
launchd agent template: [`deploy/macos/claw-fuse.plist`](deploy/macos/claw-fuse.plist).

## Systemd units ## Daily usage
| Unit | Runs | ### `claw-cargo build` (the killer app)
Wrap `cargo build` with a peer-cache lookup:
```bash
claw-cargo build \
--peer tank --peer-addr 10.0.0.14:7702 \
--tls-dir /etc/claw-store/tls \
--repo clawverse/clawstor --git-ref main \
--ref-tracking-dir /var/lib/claw-store/data \
--workspace .
```
Env-driven for CI (all above flags read `CLAWSTOR_*` env fallbacks):
```yaml
# .github/workflows/ci.yml
env:
CLAWSTOR_REPO: ${{ gitea.repository }}
CLAWSTOR_GIT_REF: ${{ gitea.ref_name }}
CLAWSTOR_DATA_DIR: /var/lib/claw-store/data
```
Detailed runner setup: [`docs/runner-integration.md`](docs/runner-integration.md).
### Named pins
```bash
# Pin the current fingerprint's cache blob under a human handle.
claw-cargo pin --name clawverse:main:latest-cache \
--peer tank --peer-addr 10.0.0.14:7702 --tls-dir /etc/claw-store/tls
# List every tag on the peer.
claw-cargo list-tags --peer tank ...
# Restore a specific tag into the local target/ without running cargo.
claw-cargo prefetch --pin clawverse:main:latest-cache --peer tank ...
# Unpin (leaves blob in place; GC reaps it when no refs remain).
claw-cargo unpin --name clawverse:main:latest-cache --peer tank ...
```
### Snapshots (immutable point-in-time records)
```bash
# Capture every blob currently on this node into a named snapshot.
claw-store cluster-snapshot-create --name pre-migration
# List everything.
claw-store cluster-snapshot-list
# See the referenced blob-ids.
claw-store cluster-snapshot-show --name pre-migration
# Delete (removes reference; blob data untouched — will vanish on next
# GC if no other pin holds it).
claw-store cluster-snapshot-delete --name pre-migration
```
Snapshots protect their blobs from LRU eviction automatically. Combined with
the daily rotation timer this gives free 30-day retention.
### Integrity + repair
```bash
# Read-only fsck: BLAKE3 verify every chunk against its manifest.
claw-store cluster-scrub
# If scrub finds corruption / missing chunks: peer-pull repair.
claw-store cluster-repair \
--peer architect --rpc-addr 10.0.0.13:7702 \
--tls-dir /etc/claw-store/tls [--dry-run]
```
### Fleet health at a glance
```bash
deploy/scripts/fleet-status.sh
```
One-line-per-node: daemon state, FUSE mount + layers, blob store size,
every timer's next-fire + last result.
### FUSE mount layout
Once `clawstor-fuse.service` is up:
```
~/clawstor-mount/
├── blobs/<blob-id-hex> # content by hash
├── refs/<fingerprint-hex> # content by cargo fingerprint
├── snapshots/<name>/<hex> # grouped by snapshot capture
└── tags/<sanitized-name> # content by human tag
```
Use with any POSIX tool:
```bash
tar -tvzf ~/clawstor-mount/tags/clawverse:main:latest-cache | head
sha256sum ~/clawstor-mount/blobs/*
find ~/clawstor-mount/snapshots -type f -newer marker
```

## CLI reference ## Prometheus metrics
```sh Each daemon exposes `/metrics` on its `prom_bind` port (7703 by convention).
claw-store activate <org/repo> # Link hot target dir, write .cargo/config.toml Sample metric families:
claw-store deactivate <org/repo> # Remove hot target dir, restore .cargo/config.toml
claw-store sync <org/repo> # git push, notify peer via SSH - `clawstor_cache_hits_total` / `_misses_total` — cache-op counters
claw-store gc # Evict stale + LRU hot targets - `clawstor_cache_hit_rate` — 0..1
claw-store snapshot # Run snapshot cycle now - `clawstor_bytes_served_total` / `_ingested_total` — traffic volumes
claw-store replicate # Run cold replication now (tank only) - `clawstor_hot_used_bytes` / `_hot_max_bytes` — tier utilization
claw-store status # Print node status - Peer discovery + gossip health via SWIM state
claw-store list # List all projects and their active state
claw-store serve # Start HTTP API + dashboard server Feed to your existing scrape config.
claw-store daemon # Start background daemon
claw-store restore <snap> <dest> # Clone snapshot into dest directory
claw-store pin <org/repo> # Mark project as pinned (survives all GC)
claw-store unpin <org/repo> # Remove pin
```
--- ---
## HTTP API ## Ongoing operations (systemd timers)
Base URL: `http://<node>:3030` Once installed, each node runs four timers on a per-day/week rhythm. All log
to `journalctl --user -u <unit>`.
| Method | Path | Description | | Timer | When | Purpose |
|---|---|---| |---|---|---|
| GET | `/api/status` | Node status (role, ZFS pool, uptime, hot usage) | | `clawstor-snapshot-rotate.timer` | daily 02:00 | Create `daily-YYYY-MM-DD` + prune `daily-*` > 30 days |
| GET | `/api/projects` | All projects with active/size/branch info | | `clawstor-ref-sweep.timer` | daily 03:15 | Query Gitea for live refs; report stale (or `--apply`) |
| GET | `/api/snapshots` | ZFS snapshot list with kind and timestamp | | `clawstor-gc.timer` | daily 03:30 | Orphan-chunk sweep. Add `--evict-to-gb N` via drop-in for size-cap fleets |
| GET | `/api/hot` | Hot tier entries with size and last-modified | | `clawstor-scrub.timer` | weekly Sun 04:00 | BLAKE3 verify every chunk. Non-zero exit = corruption |
| GET | `/api/sync-queue` | Pending sync retry jobs |
| GET | `/api/events` | SSE stream (status + projects every 5s) | Sequencing: snapshot → ref-sweep → gc → scrub so scrub reads a fresh
| POST | `/api/activate` | `{"project": "org/repo"}` | post-GC layout and eviction respects the fresh snapshot's pins.
| POST | `/api/deactivate` | `{"project": "org/repo"}` |
| POST | `/api/sync` | `{"project": "org/repo"}` |
| POST | `/api/gc` | Trigger GC pass |
| POST | `/api/snapshot` | Trigger snapshot cycle |

## SSH setup ## Testing
Tank's replication and peer-probe commands SSH to architect. The daemon runs as root (via systemd), so root's key on tank must be authorized on architect. ```bash
cargo test --bins
```sh
# On tank — generate key if not present
sudo ssh-keygen -t ed25519 -f /root/.ssh/id_ed25519 -N ""
# Copy to architect
sudo ssh-copy-id [email protected]
# Verify
sudo ssh -o BatchMode=yes [email protected] true && echo "OK"
``` ```
The peer probe in `serve.rs` uses `BatchMode=yes` (no password prompts) with a 3-second connect timeout. Replication SSH calls use `ConnectTimeout=10` with server-alive checks to prevent indefinite hangs. **389 tests** across the blob store, cluster gossip, RPC transport, WAL
replay, streaming chunk protocol, snapshot store, ref-tracking, Gitea
adapter, Tailscale identity, and every CLI handler that isn't pure glue.
Known pre-existing macOS-only failure: `hot::tests::test_project_target_size_bytes`
(du -sh idiom drift on APFS). Non-blocking for Linux CI.
Full suite via CI on every push to `main`; runners are Gitea Actions with
the `clawstor-cache:host` label.
--- ---
## Snapshot schedule ## Design docs
Snapshots are taken by `claw-store-snapshot.timer` which fires hourly. - **[`ARCHITECTURE-v2.md`](ARCHITECTURE-v2.md)** — data tiers, transport, consistency, phase plan, placement policy, cleanup modes.
- **[`docs/runner-integration.md`](docs/runner-integration.md)** — wire `claw-cargo` into your Gitea Actions workflow.
Each run: - **[`deploy/systemd/README.md`](deploy/systemd/README.md)** — install every user unit + drop-in override recipes.
- Always takes an **hourly** snapshot; prunes to `snapshot_retain_hours` - **[`deploy/macos/README.md`](deploy/macos/README.md)** — macFUSE install + launchd agent.
- At midnight (`HHMM = 0000`): also takes a **daily** snapshot; prunes to `snapshot_retain_days`
- At Sunday midnight: also takes a **weekly** snapshot; prunes to `snapshot_retain_weeks`
Snapshot names: `<dataset>@<kind>-<YYYY-MM-DD-HHMM>` e.g. `slab/projects@hourly-2026-06-30-0400`.
--- ---
## Project pinning ## Contributing
Pinned projects survive all GC passes — both the stale-hours sweep and the LRU space-pressure eviction. If every unpinned project has been evicted and the hot tier is still over budget, the daemon logs a warning and stops rather than evict pinned projects. Standard workflow:
```sh 1. Fork or branch off `main`.
claw-store pin myorg/critical-service 2. `cargo test --bins` clean.
claw-store unpin myorg/critical-service 3. `cargo clippy --bins -- -D warnings` clean.
``` 4. Open a PR at <https://git.redclaw.dev/clawverse/clawstor/pulls>.
Pinned status is stored in the manifest (`/var/lib/claw-store/manifest.toml`). Every PR gets auto-merged after CI passes if it's flagged
`polish-*`/`phase-*`; other branches await review.
--- ## License
## Troubleshooting Internal to the clawverse fleet. Not currently open-source.
**Hot tier not shrinking after gc:**
Check `journalctl -u claw-store` for "over budget but every remaining project is pinned". If so, unpin a project or raise `max_gb`.
**Replication not running on tank:**
```sh
systemctl status claw-store-replicate.timer
journalctl -u claw-store-replicate -n 50
sudo claw-store replicate # run manually, check output
```
**Snapshot cycle missed:**
```sh
systemctl status claw-store-snapshot.timer
sudo claw-store snapshot
```
**Dashboard shows uptime 0:**
The serve process reads `/var/lib/claw-store/daemon-started`. If the daemon (`claw-store.service`) isn't running, uptime will show 0.
**Peer shown as unreachable:**
SSH key not installed, or the peer's `claw-store-serve.service` is down. Run the SSH verify command above.
**`activate` fails with "non-UTF-8 path":**
Project path contains non-UTF-8 bytes. All paths under `/slab/projects` should be ASCII.
---
## Development
```sh
# Run all tests
~/.cargo/bin/cargo test --manifest-path claw-store/Cargo.toml
# Lint
~/.cargo/bin/cargo clippy --manifest-path claw-store/Cargo.toml -- -D warnings
# Release build
~/.cargo/bin/cargo build --release --manifest-path claw-store/Cargo.toml
```
Tests cover: manifest atomicity, hot GC (stale + LRU + pinning), ZFS snapshot lifecycle, weekly snapshot scheduling, incremental replication logic, HTTP handler responses, auth middleware, project name validation, and sync queue.

//! <mount>/blobs/ # dir, ls shows every blob-id in the store
//! <mount>/ # dir, contains a single `blobs` entry

//! Read-only. No writes, no metadata mutation, no permissions changes.

//! Build gate: this file is compiled only when `--features fuse` is set
//! (see Cargo.toml). Linux-only dep on the fuser crate.

//! Peer-side wiring for `deploy/scripts/safe-shutdown-prep.sh`,
//! surfaced through the RPC layer so the dashboard-v2 aggregator can
//! offer a "prepare this node for shutdown" action.
//!
//! Split into two RPCs deliberately:
//!
//! - [`Method::ShutdownPrepCheck`] runs the script's `--dry-run` mode
//! and waits for it to finish. Dry-run never stops this node's own
//! daemon, so the RPC connection survives to deliver the full
//! report — this is the part a browser can meaningfully show.
//! - [`Method::ShutdownPrepExecute`] runs the real script, which (by
//! design) stops `claw-store.service` — i.e. the very process
//! handling this RPC. There is no way to stream a live result past
//! that point, so this RPC detaches the script into its own
//! transient systemd scope (outside this daemon's service cgroup,
//! so `systemctl stop claw-store.service` doesn't take the script
//! down with it) and returns immediately. The full report lands in
//! `SHUTDOWN_PREP_LOG` for whoever is physically at the machine (or
//! over SSH) to read once the node has gone dark.

//! Snapshot store (Phase 7d).
//!
//! A **snapshot** is a named, immutable record of every blob live in
//! the store at the moment it was created. It is *not* a copy of the
//! data — blobs are content-addressed and already live under
//! `blobs/`. A snapshot is a list of `blob_id`s + wall-clock creation
//! time, stored as JSON at
//! `<root>/snapshots/<name>.json`.
//!
//! Why this exists:
//! * **Rollback anchor** — before a risky migration, snapshot the
//! current graph; if things go sideways the snapshot lists exactly
//! which blobs must survive.
//! * **Retention pin** — combined with the pin-aware LRU eviction
//! from Phase 4a, the operator can guarantee "these blobs stay on
//! disk for the next N days" without hand-listing them.
//! * **Audit** — "which blobs existed at release time?"
//!
//! Layout:
//!
//! ```text
//! <root>/snapshots/<name>.json # SnapshotManifest, JSON
//! ```
//!
//! Snapshot names are operator-supplied strings; the same
//! `validate_name` rules that guard `TagStore` apply — printable
//! non-slash characters, bounded length.

//! Tailscale identity helpers (Phase 8).
//!
//! When a laptop or roaming client wants to join the fleet, its
//! "identity" naturally includes its Tailscale hostname
//! (`laptop.taila4f562.ts.net`) and its tailnet IPv4 (`100.x.y.z`).
//! Those are what other peers will dial it by. This module reads
//! them from the local `tailscale` CLI so the operator doesn't
//! have to eyeball them off the Tailscale admin panel.
//!
//! We shell out to `tailscale status --json` rather than link
//! `tsnet` because:
//! * `tsnet` pulls a hefty Go runtime and full Tailscale client
//! into every binary.
//! * `tailscale` CLI is universally installed on any node that
//! actually uses Tailscale.
//! * The API surface we need — one identity query — is trivial.

//! `segment-<20digit-first-seq>.bin` so lexical sort equals seq
//! order. Each segment is scanned linearly. A short read or wrong
//! length prefix on the *last* segment stops the scan — the file
//! is size-truncated to the last complete record. Corruption on a
//! full-length record surfaces as a hard error.
//!
//! Phase 4d (2026-07-13): segment rotation. New records land in the
//! newest segment until it exceeds `max_segment_bytes` (default
//! 8 MiB), at which point `append` opens a new segment on the next
//! seq. Old segments become read-only. `truncate_up_to` drops whole
//! segments below the watermark and rewrites the boundary one.
//!
//! No mocks / no stubs / full impl per the delivery constraints.

//! Phase 4d (2026-07-13): typed mutation records for the WAL.
//!
//! The WAL itself (`cluster::wal`) treats payloads as opaque bytes.
//! Callers need a stable, self-describing encoding so a replay can
//! decide which RPC to re-issue on reconnect. This module owns that
//! encoding.
//!
//! Frame:
//! ```text
//! version : u8 = 0x01 today
//! kind : u8 — one of `Kind`
//! body : [u8] — kind-specific
//! ```
//!
//! Body encodings deliberately mirror the existing on-wire shapes
//! (`refs::StampedRef::to_bytes`, `tags::encode_stamped_record`,
//! ...) so a future consumer can splice a WAL record straight into
//! an RPC payload with a memcpy.
//!
//! Blob-put mutations are NOT modeled here. Blob data is too large
//! to keep in the WAL; the roaming-client design stages blobs on
//! local disk and records a reference to them once the local
//! `BlobPutStream` completes. Ref/tag updates *are* the ordered,
//! small mutations the WAL was built for.

//! Phase 4d (2026-07-13): `WalQueue` — the caller-facing wrapper

//!
//! Callers that want to add client-mode / offline durability to a

//! ```ignore

//!
//! `drain` runs `drive_replay` and, when it walked the whole log
//! cleanly, `truncate_up_to(last_applied)`. On partial progress
//! (hard error mid-stream), `truncate_up_to` still runs up to the
//! last successfully-applied seq — nothing is truncated past the
//! failure point, so the failing record and everything after it
//! are retried on the next `drain`.
//!
//! Introspection surface (`pending_count`, `oldest_pending_seq`,
//! `newest_pending_seq`, `snapshot`) is what a metrics endpoint /
//! CLI status view wants.

//! Phase 4d (2026-07-13): WAL replay engine.
//!
//! Given a peer connection and a decoded `WalMutation`, re-issue
//! the correct RPC. This is the piece that closes the loop from
//! "durably logged at client" to "actually applied at peer" on
//! reconnect.
//!
//! Failure classification is deliberate:
//!
//! * `Applied` — peer accepted the mutation (Merged, or non-versioned
//! OK).
//! * `Superseded` — peer rejected because a dominant version already
//! exists (`PutRefVersioned` / `PutTagVersioned` returning
//! `Ok(false)`; `DeleteTag` on an absent key). Not a failure —
//! the log's intent is satisfied by peer state.
//! * `Err(_)` — genuine RPC failure. Caller decides retry vs abort.
//!
//! Callers walk the WAL with `wal_mutation::replay_mutations`,
//! then feed each decoded mutation here. On `Applied` or
//! `Superseded`, advance the watermark and `wal.truncate_up_to`.
//! On error, stop and retry later — the WAL still has the record.

//! Aggregator-side session + lease store (Phase 9 S1-S3).
//!
//! A **session** is a TTL-bounded container that owns one or more
//! **tag leases**. Callers create a session, attach pins to it, and
//! either `commit` (make the tags permanent, drop tracking) or let
//! the session `expire` / `DELETE` it (unpin every tag on every peer).
//!
//! This solves the wizard-cancel problem: the client picks a repo,
//! we mint a session + pin under it, and if the browser closes we
//! reap automatically. No orphaned fleet-wide state.
//!
//! ## Persistence
//!
//! One JSON file at `path`. Rewritten on every mutation (small store,
//! aggregator only, correctness > throughput). Survives aggregator
//! restart so mid-flight leases don't leak.
//!
//! ## Concurrency
//!
//! One `RwLock<HashMap<SessionId, Session>>`. Handlers take the write
//! lock briefly (mutation + `save()`), the sweeper takes it for the
//! per-tick scan + reap. Peer fan-out RPCs happen **outside** the
//! lock so a slow peer never blocks other API calls.
//!
//! ## Auth
//!
//! Every session carries the caller's `namespace` at creation. The
//! aggregator enforces "same-namespace only" access on every session
//! endpoint. Admin callers see all sessions.

# React + TypeScript + Vite # clawstor dashboard
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules. React + Vite frontend for the (legacy) `claw-store serve` HTTP API.
Displays node status, hot-tier usage, ZFS snapshots, and the sync
queue for the original ZFS-backed deployment.
Currently, two official plugins are available: **Note:** the primary observability path in the current distributed
architecture is Prometheus (`/metrics` on each node's `prom_bind`
port, default `:7703`) + `deploy/scripts/fleet-status.sh`. This
dashboard predates that and is not maintained as the operator's
main pane of glass. Kept in-tree because the underlying HTTP
endpoints on `claw-store serve` still function.
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs) ## Build
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
## React Compiler ```bash
cd dashboard
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation). npm install
npm run build
## Expanding the ESLint configuration # → dist/ ready to serve from claw-store serve --static-dir <path>
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
```js
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Remove tseslint.configs.recommended and replace with this
tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
tseslint.configs.stylisticTypeChecked,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
``` ```
You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules: ## Dev
```js ```bash
// eslint.config.js npm run dev
import reactX from 'eslint-plugin-react-x' # Vite dev server + HMR against a running `claw-store serve` on :3030.
import reactDom from 'eslint-plugin-react-dom'
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
``` ```
## What it shows
- `/api/status` — node role, uptime, hot usage, ZFS pool.
- `/api/projects` — active + branch + size per project.
- `/api/snapshots` — ZFS snapshot list.
- `/api/hot` — hot-tier entries.
- `/api/sync-queue` — pending retries.
- `/api/events` — SSE stream, updates every 5 s.
See the top-level [README](../README.md) for the current
architecture, which centers on the distributed content-addressed
blob store rather than the ZFS project mirror model this dashboard
was originally built for.

# macOS setup (ghost, macbook, smith)
The `claw-fuse` binary supports macOS via [macFUSE](https://osxfuse.github.io).
macFUSE requires a kernel extension approval on first install — the
user has to click through System Settings → Privacy & Security →
Allow, then reboot. This is one-time.
## One-time prereqs
```bash
# macFUSE (kernel extension). Requires admin password + a reboot.
brew install --cask macfuse
# pkg-config so the fuser crate can discover macFUSE headers.
brew install pkg-config
```
After the reboot, verify:
```bash
pkg-config --modversion fuse # or `osxfuse` on older installs
```
## Build the binary
```bash
cd path/to/clawstor
cargo build --release --features fuse --bin claw-fuse
```
If pkg-config can't find `fuse`, the build will panic with an
unhelpful message from fuser's build.rs. Confirm the pkg-config
check first.
## Mount
Same CLI as Linux:
```bash
mkdir -p ~/clawstor-mount
target/release/claw-fuse \
--data-dir /path/to/clawstor/data \
--mount ~/clawstor-mount
```
## Unmount
```bash
umount ~/clawstor-mount
# or, if the process is still running:
diskutil unmount force ~/clawstor-mount
```
## launchd auto-mount (optional)
Copy [claw-fuse.plist](claw-fuse.plist) into
`~/Library/LaunchAgents/`, edit the paths to match, then:
```bash
launchctl load ~/Library/LaunchAgents/dev.clawstor.claw-fuse.plist
launchctl start dev.clawstor.claw-fuse
ls ~/clawstor-mount/
```
Unload with `launchctl unload ~/Library/LaunchAgents/dev.clawstor.claw-fuse.plist`.
## Known differences from Linux mount
* No `AllowOther` support on macFUSE by default — the mount is
visible only to the mounting user unless you set
`allow_other` in `/etc/fuse.conf` (macFUSE 4.x).
* Read-only enforcement is honored the same way. `read` /
`readdir` / `getattr` work identically.
* Unmount is `umount` (BSD) not `fusermount3 -u` (Linux).

# safe-shutdown-prep.sh — bring a clawstor node to a clean, safe stop
# before hardware maintenance (parts replacement, drive swap, etc.).
#
# Run this ON the node you're about to power off. It does NOT power
# the machine off itself — the last line of output tells you the
# command to run for that, once everything above it is clean.
#
# What it does, in order:
# 1. Refuse to proceed if a cargo/rustc build is active against a
# tracked project's warm_path (unless --force).
# 2. Refuse to proceed if the sync queue has pending jobs peers
# haven't received yet (unless --force). Gives it one chance to
# drain via `claw-store sync <project>` before failing.
# 3. Take a final ZFS snapshot of the warm tier + replicate it to
# the configured cold peer, and wait for both to finish.
# 4. Stop the four maintenance timers (scrub/gc/ref-sweep/
# snapshot-rotate) so nothing fires mid-shutdown or immediately
# after next boot before you've verified the node.
# 5. Stop claw-store-serve.service (dashboard) — no data risk, just
# tidy.
# 6. Stop claw-store.service gracefully. The unit's
# TimeoutStopSec=60 gives the daemon's SIGTERM handler room to
# let gossip announce this node's departure to peers before the
# process exits — skipping this step means peers only notice via
# the failure detector's dead_node_grace_period (10s) instead of
# an immediate clean departure.
# 7. Stop claw-fuse.service and verify the mount is actually gone
# (retries a lazy unmount if the clean one doesn't take).
# 8. Sync filesystem buffers and print zpool health for the warm
# tier's pool — warns (does not block) if the pool is degraded,
# since that's independently worth knowing before you touch
# hardware.
#
# Flags:
# --force Skip the active-build and pending-sync guards.
# Everything else (steps 3-8) still runs.
# --export-zpool Additionally `zpool export` the warm-tier pool
# at the end — only do this if you're physically
# removing the storage drives, not for e.g. a RAM
# or PSU swap. Requires a matching `zpool import`
# after the node is back up before claw-store.service
# will find its data again.
# --skip-replicate Skip step 3 (snapshot + replicate). Use only if
# you already know cold tier is current, or this
# node has no [replication] configured.
# --dry-run Run every check (steps 1-2) and the snapshot/
# replicate (step 3) for real, but only print what
# steps 4-8 (stop timers/services, unmount, zpool
# export) would do instead of doing them. Use this
# first to verify the script sees your node's
# actual state correctly before trusting it live.

# deploy/systemd
Systemd **user** units for clawstor.
## Units
| Unit | Purpose |
|---|---|
| `clawstor-cluster.service` | daemon (gossip + RPC + Prometheus + build cache). Not shipped here — deployed per-node from the fleet playbook. |
| `clawstor-fuse.service` | Phase 6 read-only FUSE mount at `~/clawstor-mount/`. Depends on `clawstor-cluster.service`. |
| `clawstor-dashboard.service` | HTTP dashboard on `:7700`. Serves the v2 SPA at `/v2/*` + `/api/v2/*`. See `docs/dashboard-v2.md`. |
| `clawstor-scrub.service` + `clawstor-scrub.timer` | Weekly (Sun 04:00) BLAKE3 verify every chunk against its manifest. Non-zero exit = integrity failure — surfaced by systemd status. |
| `clawstor-gc.service` + `clawstor-gc.timer` | Nightly (03:30) orphan-chunk sweep. Override ExecStart via drop-in to add `--evict-to-gb N` for size-cap fleets. Sequenced before the Sunday scrub so scrub reads a fresh layout. |
| `clawstor-ref-sweep.service` + `clawstor-ref-sweep.timer` | Nightly (03:15) Gitea live-refs poll + stale-fingerprint report. Set `GITEA_TOKEN` via a drop-in for private repos. Report-only (dry-run) — deletion is a follow-on. |
| `clawstor-snapshot-rotate.service` + `clawstor-snapshot-rotate.timer` | Daily (02:00) create `daily-YYYY-MM-DD` snapshot + prune snapshots older than `RETAIN_DAYS` (default 30). Only touches snapshots whose name matches `daily-*` — hand-created ones survive. |
## Install `clawstor-fuse.service` (Linux)
Prereqs: `libfuse3-dev` + `pkg-config` installed, `claw-fuse` binary built with
`cargo build --release --features fuse --bin claw-fuse`. Create the
mount directory once before enabling the unit — the unit no longer
does that itself (some Ubuntu builds refuse subsequent FUSE mounts
after an ExecStartPre chain touches the mount point):
```bash
mkdir -p ~/clawstor-mount
```
```bash
# 1. Copy the binary
cp target/release/claw-fuse ~/clawstor-deploy/claw-fuse
# 2. Install the unit
mkdir -p ~/.config/systemd/user
cp deploy/systemd/clawstor-fuse.service ~/.config/systemd/user/
# 3. Reload + enable
systemctl --user daemon-reload
systemctl --user enable --now clawstor-fuse.service
# 4. Verify
systemctl --user status clawstor-fuse.service
ls ~/clawstor-mount/ # blobs snapshots tags
```
Override the default paths with a drop-in:
```bash
systemctl --user edit clawstor-fuse.service
```
```ini
[Service]
Environment=CLAWSTOR_MOUNT=/mnt/clawstor
```
## Install `clawstor-scrub.timer`
```bash
cp deploy/systemd/clawstor-scrub.service ~/.config/systemd/user/
cp deploy/systemd/clawstor-scrub.timer ~/.config/systemd/user/
systemctl --user daemon-reload
systemctl --user enable --now clawstor-scrub.timer
# Verify:
systemctl --user list-timers clawstor-scrub.timer
# Run once manually to confirm the service works:
systemctl --user start clawstor-scrub.service
journalctl --user -u clawstor-scrub.service --since -5min
```

# dashboard-v2 — single-pane-of-glass command center
Redesign of the legacy `claw-store serve` dashboard for the current
distributed architecture.
## Design goals
1. **One URL for the whole fleet.** Hit any node's `:7700`; that node
fans out to every peer via existing QUIC RPC and serves an
aggregated view. No "3 browser tabs" pattern.
2. **Command-center landing page.** At-a-glance health strip + key
metrics + recent-events feed. Operator answers "is anything on
fire?" in <2 s.
3. **Node-detail drill-down.** Click any node in the strip → detail
page with per-node metrics, timers, storage counts, journal tail.
4. **Cross-cutting content browsers.** Blobs / Tags / Refs / Snapshots
aggregated across the fleet, searchable, click-through to detail.
5. **Trigger actions from the UI.** Scrub, GC, snapshot-create,
pin/unpin — anything currently a CLI invocation.
## Non-goals (v2 scope)
- Real-time streaming metrics beyond SSE snapshots. Prometheus stays
the source of truth for graphs; this dashboard is for state +
actions, not observability.
- Auth beyond a shared bearer token (fleet is trust-perimeter — CA
auth for the UI is future work).
- Editing configs. Read + trigger, never write config.
## Backend shape
Additive `/api/v2/*` alongside the legacy `/api/*` handlers so the
cutover is safe:
```
/api/v2/fleet aggregated snapshot (all peers)
/api/v2/node/<name>/status this-peer or remote via gossip lookup
/api/v2/node/<name>/timers systemd timer state for the 4 timers
/api/v2/node/<name>/journal?unit=… last N lines of journalctl
/api/v2/storage/blobs?limit&offset BlobStore::list_blob_ids + summaries
/api/v2/storage/tags?prefix TagStore::list (both layers)
/api/v2/storage/refs?limit&offset RefStore::list unioned
/api/v2/storage/snapshots SnapshotStore::list
/api/v2/storage/ref-tracking?repo RefTracking::list_all
/api/v2/cache/metrics router.metrics().snapshot() + gossiped
/api/v2/peers gossip snapshot + last-probe route
/api/v2/events SSE — fleet event stream
POST /api/v2/actions/scrub
POST /api/v2/actions/gc { evict_to_gb? }
POST /api/v2/actions/snapshot { name }
POST /api/v2/actions/pin { key, blob_id_hex }
POST /api/v2/actions/unpin { key }
```
## Aggregation model
**Server-side fan-out.** When the dashboard requests `/api/v2/fleet`,
the serving node walks its gossip peer list and issues a
`PeerStatus` RPC to each. Results collated into one JSON.
Trade-offs:
- Simpler frontend (no per-peer TLS material in browser).
- Backend caches results per-endpoint (5 s TTL) so 10 dashboard
tabs don't cause 30 peer RPCs.
- Any node can serve the dashboard — no "coordinator" single point
of failure.
## Frontend shape (implementation PR follows)
Routes:
```
/ → CommandCenter
/nodes/<name> → NodeDetail
/storage/blobs → StorageBrowser (blobs tab)
/storage/tags → StorageBrowser (tags tab)
/storage/refs → StorageBrowser (refs tab)
/storage/snapshots → StorageBrowser (snapshots tab)
/refs/tracking → RefTracking
/ops → OpsPanel (timers + actions + journal)
```
React + Vite + Tailwind, single SPA served from `/usr/share/claw-store/static-v2/`.
## Cutover plan
1. Ship v2 backend endpoints — legacy `/api/*` untouched.
2. Ship v2 frontend at `dashboard-v2/`, built to `static-v2/`.
3. `claw-store serve --v2-static-dir <path>` — new flag serves v2 assets at `/v2` while `/` still serves legacy for a burn-in period.
4. After burn-in: swap defaults; legacy accessible at `/legacy`.
5. Remove legacy after 30 days.
## Auth
Config-driven: `[dashboard] api_token = "..."`. Bearer required for
all POST endpoints; GET endpoints open on trusted-fleet networks
(tailscale + LAN). If token absent → POSTs disabled entirely
(read-only dashboard). Same shape as the legacy dashboard.
