docs: regenerate star history chart

* feat(filer): option to store system metadata logs in their own collection

The filer's internal /topics/.system/log chunks are assigned to the
filer's default collection (-collection). In a multi-filer deployment
that default is often empty, so every restart flap, full-sync, or
event-buffered flush grows the default collection with system chunks that
are indistinguishable from user data in collection.list. This is a large
part of what makes the default collection balloon and confuses orphan
analysis.

This keeps the internal log in a dedicated collection when the operator
asks for one, without changing where user data goes:

- New optional override, filer.options.metaLog.collection (and
  .replication), read in NewFiler so both `weed filer` and
  `weed server -filer` honour it. Default "" => exactly today's
  behaviour (log follows the filer default), fully backward compatible.
- Resolution is a small helper: override first, then the filer default,
  then a storage rule matched on the log path. Kept separate from the
  user write path so the internal log targets itself.
- bucketCollection() is hardened the same way it already protects the
  filer's default collection: a bucket that happens to resolve to the
  redirected meta-log collection must not drop it on delete, because it
  backs internal log volumes.
- Scaffold filer.toml documents the new knobs under [filer.options].

Related to the persisted deletion ledger branch (fix/persist-deletion-queue):
together they cut the two sources of post-flap junk in the default
collection — that PR stops orphaned user-chunk leak on filer crash,
this one stops the internal log from living in default at all. They are
independent: no file overlap, no functional dependency; either can merge
first. They are paired only in the narrative of cleaning up default.

Adds unit tests for the collection/replication resolution chain, the
viper keys, and the bucket-delete guard (run green under -race).

* filer: collect bucket chunks when its collection survives the delete

bucketCollection returning "" preserves the collection, but the bucket
path still skipped per-entry chunk collection and could skip listing the
children entirely, so a bucket sharing the meta-log (or any preserved)
collection left its object chunks orphaned with no entry pointing at
them. Only the wholesale drop of a deleted collection skips those now.

Note in filer.toml that the meta-log target should stay stable: chunks
written under an older collection are not migrated.

* filer: exercise the metaLog override wiring through NewFiler

The viper test only echoed back the keys it set, so a wrong key in
NewFiler would still pass. It now asserts the fields NewFiler fills
from those keys.

+One `weed` binary serves an S3 object store, a POSIX file system, and a lakehouse with S3 Tables, all over the same data. Each blob is one disk read away, capacity grows by starting another volume server, and cloud storage can be cached or tiered transparently. Both read and write operations have O(1) complexity and can run at the full speed supported by the underlying hardware.

 # Quick Start #
 
+## One command ##
 
-## Quick Start with weed mini ##
+Download the latest binary from the [releases](https://github.com/seaweedfs/seaweedfs/releases/latest) page and unzip the single `weed` (or `weed.exe`) file, or let the install script put it in `/usr/local/bin`:
 
-Download the latest binary from https://github.com/seaweedfs/seaweedfs/releases and unzip the single `weed` (or `weed.exe`) file, or run `go install github.com/seaweedfs/seaweedfs/weed@latest`. Then start a ready-to-use S3 object store with credentials and a pre-created bucket in one command:
+```bash
+curl -fsSL https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/install.sh | bash
+```
+
+Then start a ready-to-use S3 object store:
 
 ```bash
 AWS_ACCESS_KEY_ID=admin \
 AWS_SECRET_ACCESS_KEY=secret \
 S3_BUCKET=my-bucket \
-./weed mini -dir=/data
+./weed mini -dir=./data
 ```
 
-That's it — the S3 endpoint is at http://localhost:8333, `my-bucket` already exists, and `admin`/`secret` are valid credentials. `S3_BUCKET` accepts a comma-separated list (e.g. `raw,processed`); use `S3_TABLE_BUCKET` for S3 Tables (Iceberg) buckets. Drop any of the env vars to skip that piece (no AWS keys → S3 runs in unauthenticated "Allow All" mode for development).
+That's it. The S3 endpoint is at http://localhost:8333, `my-bucket` exists, and `admin`/`secret` are valid credentials:
 
-The same command starts everything else too:
-- **S3 Endpoint**: http://localhost:8333
-- **Master UI**: http://localhost:9333
-- **Volume Server**: http://localhost:9340
-- **Filer UI**: http://localhost:8888
-- **WebDAV**: http://localhost:7333
-- **Admin UI**: http://localhost:23646
+```bash
+AWS_ACCESS_KEY_ID=admin AWS_SECRET_ACCESS_KEY=secret \
+  aws --endpoint-url http://localhost:8333 s3 cp README.md s3://my-bucket/
+```
+
+The same process also runs the master, a volume server, the filer, WebDAV, the Iceberg REST catalog, and the Admin UI. Add `S3_TABLE_BUCKET=warehouse` to also create an Iceberg table bucket, or `warehouse:LANCE` for a Lance one. Drop the AWS keys to run without authentication for development.
 
 > macOS: if the binary is quarantined, run `xattr -d com.apple.quarantine ./weed` first.
 
-Perfect for development, testing, learning SeaweedFS, and single-node deployments. To scale out, add more volume servers by running `weed volume -dir="/some/data/dir2" -master="<master_host>:9333" -port=8081` locally, on another machine, or on thousands of machines.
+`weed mini` is auto-tuned for one node and is fine for single-node production, such as an S3 gateway that issues presigned URLs. See [Quick Start with weed mini][WeedMini].
 
-## Quick Start for S3 API on Docker ##
+## Docker ##
 
 ```bash
-docker run -p 8333:8333 \
+docker run -p 8333:8333 -v weed-data:/data \
   -e AWS_ACCESS_KEY_ID=admin \
   -e AWS_SECRET_ACCESS_KEY=secret \
   -e S3_BUCKET=my-bucket \
   chrislusf/seaweedfs
 ```
 
-Same behavior as the `weed mini` command above — the S3 endpoint is at http://localhost:8333 with `my-bucket` pre-created. Drop the env vars to run anonymously for development.
+Same behavior as the `weed mini` command above.
 
-# Introduction #
+## Docker Compose ##
 
-SeaweedFS is a simple and highly scalable distributed file system. There are two objectives:
+To run master, volume server, filer, S3, and WebDAV as separate services:
 
-1. to store billions of files!
-2. to serve the files fast!
+```bash
+wget https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/docker/seaweedfs-compose.yml
+wget -P prometheus https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/docker/prometheus/prometheus.yml
+docker compose -f seaweedfs-compose.yml -p seaweedfs up
+```
 
-SeaweedFS started as a blob store to handle small files efficiently. 
-Instead of managing all file metadata in a central master, 
-the central master only manages volumes on volume servers, 
-and these volume servers manage files and their metadata. 
-This relieves concurrency pressure from the central master and spreads file metadata into volume servers, 
-allowing faster file access (O(1), usually just one disk read operation).
+[Docker Compose for S3][DockerComposeS3] adds credentials, and the [docker/compose](docker/compose) folder has variants for replication, mounts, message queues, and more.
 
-There is only 40 bytes of disk storage overhead for each file's metadata. 
-It is so simple with O(1) disk reads that you are welcome to challenge the performance with your actual use cases.
+## Kubernetes with Helm ##
 
-SeaweedFS started by implementing [Facebook's Haystack design paper](http://www.usenix.org/event/osdi10/tech/full_papers/Beaver.pdf). 
-Also, SeaweedFS implements erasure coding with ideas from 
-[f4: Facebook’s Warm BLOB Storage System](https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-muralidhar.pdf), and has a lot of similarities with [Facebook’s Tectonic Filesystem](https://www.usenix.org/system/files/fast21-pan.pdf) and [Google's Colossus File System](https://cloud.google.com/blog/products/storage-data-transfer/a-peek-behind-colossus-googles-file-system)
+```bash
+helm repo add seaweedfs https://seaweedfs.github.io/seaweedfs/helm
+helm install seaweedfs seaweedfs/seaweedfs -n seaweedfs --create-namespace -f values.yaml
+```
 
-On top of the blob store, optional [Filer] can support directories and POSIX attributes. 
-Filer is a separate linearly-scalable stateless server with customizable metadata stores, 
-e.g., MySql, Postgres, Redis, Cassandra, HBase, Mongodb, Elastic Search, LevelDB, RocksDB, Sqlite, MemSql, TiDB, Etcd, CockroachDB, YDB, etc.
+A production-shaped `values.yaml` for a three-node cluster: two copies of every write, three masters, and an S3 endpoint with credentials and a bucket.
 
-SeaweedFS can transparently integrate with the cloud. 
-With hot data on local cluster, and warm data on the cloud with O(1) access time, 
-SeaweedFS can achieve both fast local access time and elastic cloud storage capacity.
-What's more, the cloud storage access API cost is minimized. 
-Faster and cheaper than direct cloud storage!
+```yaml
+global:
+  seaweedfs:
+    enableReplication: true
+    replicationPlacement: "001"   # one extra copy on another server; "002" for two
 
-SeaweedFS also ships a built-in **Iceberg REST Catalog**, turning the same cluster into a self-contained lakehouse.
-Spark, Trino, Dremio, DuckDB, and RisingWave can query Iceberg tables directly — no Hive Metastore, Glue, or
-external catalog service required. Storage and table metadata live in one system, simplifying on-prem and
-small-team analytics stacks.
+master:
+  replicas: 3
+  data:
+    type: persistentVolumeClaim   # the cluster's default storage class; add storageClass to pick one
+    size: 1Gi
+
+volume:
+  replicas: 3                     # at least 1 + the sum of the replication digits
+  dataDirs:
+    - name: data
+      type: persistentVolumeClaim
+      size: 500Gi
+      maxVolumes: 0               # size the volume count from the disk
+
+filer:
+  replicas: 2
+  data:
+    type: persistentVolumeClaim
+    size: 20Gi
+
+s3:
+  enabled: true
+  replicas: 2
+  enableAuth: true
+  credentials:
+    admin:
+      accessKey: admin
+      secretKey: change-me
+  createBuckets:
+    - name: app-storage
+```
+
+The S3 endpoint is the `seaweedfs-s3` service on port 8333. [Helm Chart Recipes][HelmRecipes] has values for a development cluster, a lakehouse with the Iceberg catalog exposed, filer metadata on PostgreSQL, and node-local disks. The [SeaweedFS Operator][Operator] and the [CSI driver][SeaweedFsCsiDriver] are the other Kubernetes paths.
+
+## Build from source ##
+
+```bash
+git clone https://github.com/seaweedfs/seaweedfs.git
+cd seaweedfs/weed && make install
+```
+
+`weed` lands in `$GOPATH/bin`. [Getting Started][GettingStarted] covers running master, volume, filer, and S3 as separate processes.
+
+## Scale out ##
+
+Capacity is a volume server. Start one on any machine with disk and point it at the master:
+
+```bash
+weed volume -dir=/data -master=<master_host>:9333
+```
+
+Nothing rebalances until you ask it to. Throughput is a filer or S3 gateway; they are stateless, so run as many as you need behind a load balancer. [Production Setup][ProductionSetup] walks through a multi-node cluster.

-# Features #
-## Additional Blob Store Features ##
-* Support different replication levels, with rack and data center aware.
-* Automatic master servers failover - no single point of failure (SPOF).
-* Automatic compression depending on file MIME type.
-* Automatic compaction to reclaim disk space after deletion or update.
-* [Automatic entry TTL expiration][VolumeServerTTL].
-* Flexible Capacity Expansion: Any server with some disk space can add to the total storage space.
-* Adding/Removing servers does **not** cause any data re-balancing unless triggered by admin commands.
-* Optional picture resizing.
-* Support ETag, Accept-Range, Last-Modified, etc.
-* Support in-memory/leveldb/readonly mode tuning for memory/performance balance.
-* Support rebalancing the writable and readonly volumes.
-* [Customizable Multiple Storage Tiers][TieredStorage]: Customizable storage disk types to balance performance and cost.
-* [Transparent cloud integration][CloudTier]: unlimited capacity via tiered cloud storage for warm data.
-* [Erasure Coding for warm storage][ErasureCoding]  Rack-Aware 10.4 erasure coding reduces storage cost and increases availability. Enterprise version can customize EC ratio.
+# Why SeaweedFS #
+
+## Fast ##
+
+* One disk read per blob. A small file is one blob; a large file is split into chunks of a few MB, each its own blob. A volume server keeps a 16-byte index entry per blob in memory and reads it in a single seek, also for erasure-coded data.
+* The master is not in the read path. Clients cache the volume-to-server mapping and talk to volume servers directly.
+* 40 bytes of metadata per file on disk. Small files are packed into append-only volume files, so there is no per-file inode, no per-file metadata file, no fragmentation, and writes are SSD friendly.
+* Hot data is replicated; [erasure coding][ErasureCoding] is applied to warm data in the background, so writes never pay the encoding cost.
+* The [Rust volume server][RustVolume] is a drop-in for higher throughput and lower tail latency on the same on-disk format.
+
+On one laptop, [`weed benchmark`][Benchmarks] writes 1KB files at 15,700 per second and reads them back at 47,000 per second, and a mixed S3 [warp][S3Benchmark] run totals 3.2 GiB/s. Numbers are in the [Benchmark](#benchmark) section; throughput grows with volume servers and gateways.
+
+## Scalable ##
+
+* The master tracks volumes, not files. A cluster with billions of files has a few thousand volumes, so the master stays small. One master is enough for most clusters; run three for [Raft failover][FailoverMaster].
+* Adding a server adds capacity with no data reshuffle. Balancing, vacuum, erasure coding, and repair run on demand from [`weed shell`][WeedShell] or the [maintenance worker][Worker].
+* Filer and S3 gateways are stateless and scale linearly. Directory metadata lives in a [store you already run][FilerStores]: LevelDB, RocksDB, SQLite, MySQL, PostgreSQL, Cassandra, HBase, MongoDB, Redis, Elasticsearch, etcd, TiKV, FoundationDB, YDB, ArangoDB, Tarantool, and MySQL or PostgreSQL compatible databases such as TiDB, CockroachDB, and MemSQL.
+* Rack and data center aware [replication][Replication], [tiered storage][TieredStorage] across disk types, and [transparent cloud tiering][CloudTier] for unlimited capacity.
+* Files from a byte to [tens of TB][SuperLargeFiles]. Volumes up to 8TB with the large-disk build.
+
+## The most complete S3 API ##
+
+The S3 gateway implements the object, bucket, S3 Tables, IAM, and STS APIs on one endpoint, so the AWS SDKs and CLI, rclone, restic, Spark, and Trino work unchanged.
+
+| API | Operations |
+| --- | --- |
+| S3 bucket and object | 73 |
+| S3 Tables | 36 |
+| IAM | 39 |
+| STS | 5 |
+
+* [Versioning][Versioning], [Object Lock][ObjectLock] with retention and legal hold, [lifecycle][Lifecycle] rules, tagging, [CORS][CORS], [conditional reads and writes][ConditionalOps], checksums, presigned URLs, browser POST uploads, multipart uploads, and an atomic [RenameObject][RenameObject].
+* [Bucket policies][BucketPolicies] with [conditions][PolicyConditions] and [variables][PolicyVariables]; IAM users, groups, and policies; STS with [OIDC][OIDC], LDAP, and [Kubernetes service accounts][K8sSA].
+* [SSE-S3, SSE-KMS, and SSE-C][SSE] server-side encryption, with OpenBao and Vault, AWS KMS, Azure Key Vault, and GCP KMS as key providers.
+* [Audit log][AuditLog], [bucket quota][BucketQuota], and [rate limiting][RateLimiting].
+* Each bucket is its own collection, so deleting a bucket is instant.
+
+The full operation list is in [Amazon S3 API][AmazonS3API], and [Supported APIs vs MinIO][S3vsMinio] compares. The S3 compatibility suite and the SDK, IAM, SSE, policy, and Spark integration tests run in CI on every change.
+
+## A data warehouse with S3 Tables ##
+
+SeaweedFS is a lakehouse in one system. [S3 Table Buckets][S3TableBucket] hold Apache Iceberg tables by default, or [Lance][LanceCatalog] tables for vectors and multimodal data, and the built-in [Iceberg REST Catalog][IcebergCatalog] and Lance namespace serve them directly. There is no Hive Metastore, Glue, or separate catalog service to deploy, secure, and back up.
+
+* Query engines operate on the same tables at the same time: [Spark][SparkIceberg], [Trino][TrinoIceberg], [Dremio][DremioIceberg], [DuckDB][DuckDBIceberg], [Apache Doris][DorisIceberg], [RisingWave][RisingWaveIceberg], ClickHouse, and [LanceDB][LanceDB]. Catalog commits are atomic compare-and-swap, so concurrent writers are safe. [Lakekeeper][Lakekeeper] can front the same storage with STS-vended credentials.
+* [Automated table maintenance][IcebergMaintenance]: compaction, snapshot expiration, orphan file removal, and manifest rewriting, configured per bucket or table through the S3 Tables maintenance APIs, and the same for [Lance][LanceMaintenance].
+* IAM at the bucket, namespace, and table level with standard bucket policies, see [S3 Tables Security][S3TablesSecurity].
+* A [Hadoop compatible file system][Hadoop] for Spark, Flink, and HBase.
+
+`S3_TABLE_BUCKET=warehouse ./weed mini -dir=./data` brings the whole stack up on a laptop.
+
+## A fast cache for cloud storage ##
+
+[Cloud Drive][CloudDrive] mounts a bucket from S3, Google Cloud Storage, Azure, Backblaze B2, Wasabi, Storj, or any S3-compatible store into SeaweedFS and serves it at local speed:
+
+* Metadata is pulled once, so listing, stat, and directory walks cost no cloud API calls.
+* File content is downloaded once, on first read or [warmed][CacheRemote] by folder, name pattern, size, or age, and cached with the capacity of the whole cluster: cache everything, no churn.
+* Local writes complete at local latency and are written back to the cloud asynchronously in the cloud's native layout, so other tools keep reading the bucket directly.
+* Uncache by the same rules to free local disk while keeping the metadata.
+
+[Cloud Tier][CloudTier] goes the other direction, moving whole warm volumes to cloud storage while keeping one-read access, and the [Gateway to Remote Object Storage][GatewayToRemoteObjectStore] mirrors every bucket to a remote store. Faster and cheaper than reading the cloud directly.
+
+## Active-active replication and more ##
+
+* [Active-active or active-passive replication][ActiveActiveAsyncReplication] between clusters, continuous and resumable, for the whole tree or chosen folders, across data centers.
+* [Filer store replication][FilerStoreReplication] for metadata HA, [async backup][AsyncBackup] to cloud storage, [metadata backup][MetaBackup], and [change data capture][CDC] with [webhooks][Webhook] on every metadata event.
+* The same data as a [FUSE mount][Mount] on Linux, macOS, and [Windows][MountWindows], over [WebDAV][WebDAV], [SFTP][SFTP], HDFS, HTTP, and [TUS resumable uploads][TUS]; on Kubernetes through the [CSI driver][SeaweedFsCsiDriver] and [Operator][Operator].
+* [AES256-GCM encryption at rest][FilerDataEncryption], TLS and mTLS between components, JWT-signed volume access, and [FIPS][FIPS] builds.
+* [Admin UI][AdminUI], Prometheus [metrics][Metrics], [TTL][VolumeServerTTL] per file or volume, automatic compression and compaction, and [seaweed-up][SeaweedUp] for bare-metal clusters.

+* **Master** servers, one or a Raft group of three, track which volume lives on which volume server and hand out file ids. They are not in the read path.
+* **Volume** servers store blobs in append-only volume files, keep a 16-byte in-memory index per blob, and replicate or erasure-code at the volume level.
+* **Filer** servers add directories and files on top, with metadata in a store of your choice, and expose HTTP, S3, WebDAV, SFTP, FUSE, and the table catalogs.
 
+The blob store started from [Facebook's Haystack](http://www.usenix.org/event/osdi10/tech/full_papers/Beaver.pdf), erasure coding takes ideas from [f4](https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-muralidhar.pdf), and the whole has a lot in common with [Tectonic](https://www.usenix.org/system/files/fast21-pan.pdf) and [Colossus](https://cloud.google.com/blog/products/storage-data-transfer/a-peek-behind-colossus-googles-file-system). How file ids are assigned, written, and looked up, and why a master that tracks volumes scales, is in [Blob Store Architecture][BlobStoreArchitecture]; the services are in [Components][Components] and the [white paper][WhitePaper].

-## Example: Using Seaweed Blob Store ##
-
-By default, the master node runs on port 9333, and the volume nodes run on port 8080.
-Let's start one master node, and two volume nodes on port 8080 and 8081. Ideally, they should be started from different machines. We'll use localhost as an example.
-
-SeaweedFS uses HTTP REST operations to read, write, and delete. The responses are in JSON or JSONP format.
-
-### Start Master Server ###
-
-```
-> ./weed master
-```
-
-### Start Volume Servers ###
-
-```
-> weed volume -dir="/tmp/data1" -max=5  -master="localhost:9333" -port=8080 &
-> weed volume -dir="/tmp/data2" -max=10 -master="localhost:9333" -port=8081 &
-```
-
-### Write A Blob ###
-
-A blob, also referred as a needle, a chunk, or mistakenly as a file, is just a byte array. It can have attributes, such as name, mime type, create or update time, etc. But basically it is just a byte array of a relatively small size, such as 2 MB ~ 64 MB. The size is not fixed.
-
-To upload a blob: first, send a HTTP POST, PUT, or GET request to `/dir/assign` to get an `fid` and a volume server URL:
-
-```
-> curl http://localhost:9333/dir/assign
-{"count":1,"fid":"3,01637037d6","url":"127.0.0.1:8080","publicUrl":"localhost:8080"}
-```
-
-Second, to store the blob content, send a HTTP multi-part POST request to `url + '/' + fid` from the response:
-
-```
-> curl -F file=@/home/chris/myphoto.jpg http://127.0.0.1:8080/3,01637037d6
-{"name":"myphoto.jpg","size":43234,"eTag":"1cc0118e"}
-```
-
-To update, send another POST request with updated blob content.
-
-For deletion, send an HTTP DELETE request to the same `url + '/' + fid` URL:
-
-```
-> curl -X DELETE http://127.0.0.1:8080/3,01637037d6
-```
-
-### Save Blob Id ###
-
-Now, you can save the `fid`, 3,01637037d6 in this case, to a database field.
-
-The number 3 at the start represents a volume id. After the comma, it's one file key, 01, and a file cookie, 637037d6.
-
-The volume id is an unsigned 32-bit integer. The file key is an unsigned 64-bit integer. The file cookie is an unsigned 32-bit integer, used to prevent URL guessing.
-
-The file key and file cookie are both coded in hex. You can store the <volume id, file key, file cookie> tuple in your own format, or simply store the `fid` as a string.
-
-If stored as a string, in theory, you would need 8+1+16+8=33 bytes. A char(33) would be enough, if not more than enough, since most uses will not need 2^32 volumes.
-
-If space is really a concern, you can store the file id in the binary format. You would need one 4-byte integer for volume id, 8-byte long number for file key, and a 4-byte integer for the file cookie. So 16 bytes are more than enough.
-
-### Read a Blob ###
-
-Here is an example of how to render the URL.
-
-First look up the volume server's URLs by the file's volumeId:
-
-```
-> curl http://localhost:9333/dir/lookup?volumeId=3
-{"volumeId":"3","locations":[{"publicUrl":"localhost:8080","url":"localhost:8080"}]}
-```
-
-Since (usually) there are not too many volume servers, and volumes don't move often, you can cache the results most of the time. Depending on the replication type, one volume can have multiple replica locations. Just randomly pick one location to read.
-
-Now you can take the public URL, render the URL or directly read from the volume server via URL:
-
-```
- http://localhost:8080/3,01637037d6.jpg
-```
-
-Notice we add a file extension ".jpg" here. It's optional and just one way for the client to specify the file content type.
-
-If you want a nicer URL, you can use one of these alternative URL formats:
-
-```
- http://localhost:8080/3/01637037d6/my_preferred_name.jpg
- http://localhost:8080/3/01637037d6.jpg
- http://localhost:8080/3,01637037d6.jpg
- http://localhost:8080/3/01637037d6
- http://localhost:8080/3,01637037d6
-```
-
-If you want to get a scaled version of an image, you can add some params:
-
-```
-http://localhost:8080/3/01637037d6.jpg?height=200&width=200
-http://localhost:8080/3/01637037d6.jpg?height=200&width=200&mode=fit
-http://localhost:8080/3/01637037d6.jpg?height=200&width=200&mode=fill
-```
-
-### Rack-Aware and Data Center-Aware Replication ###
-
-SeaweedFS applies the replication strategy at a volume level. So, when you are getting a blob id, you can specify the replication strategy. For example:
-
-```
-curl http://localhost:9333/dir/assign?replication=001
-```
-
-The replication parameter options are:
-
-```
-000: no replication
-001: replicate once on the same rack
-010: replicate once on a different rack, but same data center
-100: replicate once on a different data center
-200: replicate twice on two different data center
-110: replicate once on a different rack, and once on a different data center
-```
-
-More details about replication can be found [on the wiki][Replication].
-
-[Replication]: https://github.com/seaweedfs/seaweedfs/wiki/Replication
-
-You can also set the default replication strategy when starting the master server.
-
-### Allocate Blob Key on Specific Data Center ###
-
-Volume servers can be started with a specific data center name:
-
-```
- weed volume -dir=/tmp/1 -port=8080 -dataCenter=dc1
- weed volume -dir=/tmp/2 -port=8081 -dataCenter=dc2
-```
-
-When requesting a blob key, an optional "dataCenter" parameter can limit the assigned volume to the specific data center. For example, this specifies that the assigned volume should be limited to 'dc1':
-
-```
- http://localhost:9333/dir/assign?dataCenter=dc1
-```

-## Blob Store Architecture ##
-
-Usually distributed file systems split each file into chunks. A central server keeps a mapping of filenames to chunks, and also which chunks each chunk server has.
-
-The main drawback is that the central server can't handle many small files efficiently, and since all read requests need to go through the central master, so it might not scale well for many concurrent users.
-
-Instead of managing chunks, SeaweedFS manages data volumes in the master server. Each data volume is 32GB in size, and can hold a lot of blobs. And each storage node can have many data volumes. So the master node only needs to store the metadata about the volumes, which is a fairly small amount of data and is generally stable.
-
-The actual blob metadata, which are the blob volume, offset, and size, is stored in each volume on volume servers. Since each volume server only manages metadata of blobs on its own disk, with only 16 bytes for each blob, all access can read the metadata just from memory and only needs one disk operation to actually read file data.
-
-For comparison, consider that an xfs inode structure in Linux is 536 bytes.
-
-### Master Server and Volume Server ###
-
-The architecture is fairly simple. The actual data is stored in volumes on storage nodes. One volume server can have multiple volumes, and can both support read and write access with basic authentication.
-
-All volumes are managed by a master server. The master server contains the volume id to volume server mapping. This is fairly static information, and can be easily cached.
-
-On each write request, the master server also generates a file key, which is a growing 64-bit unsigned integer. Since write requests are not generally as frequent as read requests, one master server should be able to handle the concurrency well.
-
-### Write and Read files ###
-
-When a client sends a write request, the master server returns (volume id, file key, file cookie, volume node URL) for the blob. The client then contacts the volume node and POSTs the blob content.
-
-When a client needs to read a blob based on (volume id, file key, file cookie), it asks the master server by the volume id for the (volume node URL, volume node public URL), or retrieves this from a cache. Then the client can GET the content, or just render the URL on web pages and let browsers fetch the content.
-
-### Saving memory ###
-
-All blob metadata stored on a volume server is readable from memory without disk access. Each file takes just a 16-byte map entry of <64bit key, 32bit offset, 32bit size>. Of course, each map entry has its own space cost for the map. But usually the disk space runs out before the memory does.
-
-### Tiered Storage to the cloud ###
-
-The local volume servers are much faster, while cloud storages have elastic capacity and are actually more cost-efficient if not accessed often (usually free to upload, but relatively costly to access). With the append-only structure and O(1) access time, SeaweedFS can take advantage of both local and cloud storage by offloading the warm data to the cloud.
-
-Usually hot data are fresh and warm data are old. SeaweedFS puts the newly created volumes on local servers, and optionally upload the older volumes on the cloud. If the older data are accessed less often, this literally gives you unlimited capacity with limited local servers, and still fast for new data. 
-
-With the O(1) access time, the network latency cost is kept at minimum. 
-
-If the hot/warm data is split as 20/80, with 20 servers, you can achieve storage capacity of 100 servers. That's a cost saving of 80%! Or you can repurpose the 80 servers to store new data also, and get 5X storage throughput.

-## Disk Related Topics ##
-
-### Hard Drive Performance ###
-
-When testing read performance on SeaweedFS, it basically becomes a performance test of your hard drive's random read speed. Hard drives usually get 100MB/s~200MB/s.
-
-### Solid State Disk ###
-
-To modify or delete small files, SSD must delete a whole block at a time, and move content in existing blocks to a new block. SSD is fast when brand new, but will get fragmented over time and you have to garbage collect, compacting blocks. SeaweedFS is friendly to SSD since it is append-only. Deletion and compaction are done on volume level in the background, not slowing reading and not causing fragmentation.

+# SeaweedFS HTTP REST API
+
+SeaweedFS exposes three HTTP surfaces:
+
+| Service | Default port | Addressing |
+|---------|--------------|------------|
+| Filer | 8888 | File system paths (`/dir/name`) |
+| Master | 9333 | File id assignment and cluster topology |
+| Volume server | 8080 | File content by file id (`vid,fid`) |
+
+Most clients only need the filer API (paths) or the S3 API. The master and
+volume APIs are the lower-level blob store interface.
+
+Conventions applying to all three:
+
+- Responses are JSON unless noted otherwise. Append `&pretty=y` to pretty-print.
+- A file id (`fid`) has the form `volumeId,fileKeyCookie`, e.g. `3,01637037d6`.
+  An optional suffix selects a reserved id from a `count` assignment
+  (`3,01637037d6_1`, `_2`, ...), and an optional extension
+  (`3,01637037d6.jpg`) sets the content type on reads.
+- `replication` is a 3-digit replica placement `xyz`: `x` copies in other
+  data centers, `y` on other racks in the same data center, `z` on other
+  volume servers on the same rack. `000` = no replication, `001` = one copy
+  on the same rack, `010` = one copy on a different rack, `100` = one copy in
+  another data center, `200` = two copies in two other data centers, `110` =
+  one copy in another data center plus one on another rack.
+- `ttl` units: `m` minute, `h` hour, `d` day, `w` week, `M` month, `y` year.
+
+## Filer API (port 8888)
+
+The filer presents a POSIX-like namespace over the volume servers.
+
+### Upload a file
+
+```bash
+# PUT the raw body to the target path
+curl -T /home/chris/myphoto.jpg "http://localhost:8888/dir/myphoto.jpg"
+
+# or POST as multipart form (the part filename becomes the entry name)
+curl -F file=@/home/chris/myphoto.jpg "http://localhost:8888/dir/"
+```
+
+Response `201 Created`:
+
+```json
+{"name":"myphoto.jpg","size":43234,"eTag":"0x6c656...","mtime":"...","chunks":[...]}
+```
+
+Query parameters:
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `collection` | collection name | empty |
+| `replication` | replica placement code | filer default |
+| `ttl` | file expiration, e.g. `3d` | never |
+| `disk` | disk type to store on | filer default |
+| `fsync` | `true` fsyncs on the volume server | false |
+| `dataCenter` | preferred data center | empty |
+| `rack` | preferred rack | empty |
+| `dataNode` | preferred volume server | empty |
+| `saveInside` | store small content inside the metadata instead of a volume | false |
+| `maxMB` | split the upload into chunks of this many MB | filer `-maxMB` |
+| `mode` | unix permission bits, e.g. `0644` | `0660` |
+| `op` | `append` appends to an existing file | overwrite |
+| `skipCheckParentDir` | `true` skips the parent-directory existence check | false |
+
+### Create a directory
+
+```bash
+curl -X POST "http://localhost:8888/dir/newdir/"
+```
+
+A POST to a path ending in `/` with no content creates the directory,
+including missing parents.
+
+### Read a file
+
+```bash
+curl "http://localhost:8888/dir/myphoto.jpg"
+```
+
+Supports `Range` requests (`Accept-Ranges: bytes`), `ETag`, and the
+`If-None-Match` / `If-Modified-Since` conditional headers. `HEAD` returns
+headers only. Entry headers stored as extended attributes are echoed back,
+minus internal `Seaweed-` and `xattr-` keys.
+
+Entry metadata instead of content:
+
+```bash
+curl "http://localhost:8888/dir/myphoto.jpg?metadata=true"
+```
+
+`metadata=true&resolveManifest=true` additionally resolves chunked-manifest
+entries into their real chunk list.
+
+### List a directory
+
+```bash
+curl -H "Accept: application/json" "http://localhost:8888/dir/?limit=10&lastFileName=a.jpg"
+```
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `limit` | max entries per page | filer `-dirListLimit` |
+| `lastFileName` | resume listing after this entry name | empty |
+| `namePattern` | include only names matching the wildcard | empty |
+| `namePatternExclude` | exclude names matching the wildcard | empty |
+
+The JSON response carries `Path`, `Entries`, `Limit`, `LastFileName`,
+`ShouldDisplayLoadMore`, and `EmptyFolder`. Without the `Accept` header the
+filer renders its HTML browser.
+
+### Move and copy
+
+```bash
+curl -X POST "http://localhost:8888/dir/newname.jpg?mv.from=/dir/myphoto.jpg"
+curl -X POST "http://localhost:8888/dir/copy.jpg?cp.from=/dir/myphoto.jpg"
+```
+
+`mv.from` renames or moves the source to the request path (`204 No Content`).
+`cp.from` copies it.
+
+### Append
+
+```bash
+curl -T chunk2.bin "http://localhost:8888/dir/file.bin?op=append"
+```
+
+### Delete
+
+```bash
+curl -X DELETE "http://localhost:8888/dir/myphoto.jpg"
+curl -X DELETE "http://localhost:8888/dir/?recursive=true"
+```
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `recursive` | delete a non-empty directory tree | false; when the filer runs with `filer.options.recursive_delete=true`, deletes are recursive unless `recursive=false` |
+| `ignoreRecursiveError` | keep deleting remaining entries after an error | false |
+| `skipChunkDeletion` | remove only the metadata, keep volume data | false |
+
+### Tagging
+
+Tags are carried as `Seaweed-`-prefixed request headers, not query
+parameters; `?tagging` selects the tagging handler and `?tagging=K1,K2`
+lists the keys to remove. Header names are canonicalized on write
+(`Seaweed-k1` is stored as `Seaweed-K1`), and the delete list is matched
+case-sensitively against the stored names.
+
+```bash
+curl -X PUT -H "Seaweed-k1: v1" -H "Seaweed-k2: v2" "http://localhost:8888/dir/file.jpg?tagging"
+curl -X DELETE "http://localhost:8888/dir/file.jpg?tagging=K1,K2"
+```
+
+### Read by file id
+
+```bash
+curl "http://localhost:8888/?proxyChunkId=3,01637037d6"
+```
+
+The filer proxies the chunk read to the right volume server, so only the
+filer port needs to be exposed.
+
+### Resumable uploads
+
+The filer serves the [TUS protocol](https://tus.io/) for resumable uploads
+(`POST`, `PATCH`, `HEAD` on upload URLs). It is enabled by default at
+`/.tus`; `-tusBasePath` changes the endpoint base path.
+
+### Health
+
+`GET /healthz` and `GET /readyz` return `200 OK`.
+
+## Master API (port 9333)
+
+Write-affecting endpoints are automatically proxied to the current leader, so
+any master in the quorum can serve them.
+
+### Assign a file id
+
+```bash
+curl "http://localhost:9333/dir/assign?count=1&replication=001&collection=turbo&dataCenter=dc1&ttl=3d&disk=ssd"
+{"count":1,"fid":"3,01637037d6","url":"127.0.0.1:8080","publicUrl":"localhost:8080"}
+```
+
+Upload the file content to `http://<url>/<fid>` afterwards. With `count>1`,
+use `<fid>_1`, `<fid>_2`, ... for the additional ids.
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `count` | file ids to reserve | 1 |
+| `collection` | collection name | empty |
+| `dataCenter` | preferred data center | empty |
+| `rack` | preferred rack | empty |
+| `dataNode` | preferred volume server | empty |
+| `replication` | replica placement | master `-defaultReplication` |
+| `ttl` | file expiration, e.g. `3d` | never |
+| `disk` | disk type | empty |
+| `dataSize` | expected file size in bytes | 0 |
+| `preallocate` | bytes to preallocate for new volumes | master `-volumePreallocate` |
+| `writableVolumeCount` | grow this many volumes when none are writable | master default |
+| `memoryMapMaxSizeMb` | memory-mapped file size (Windows) | 0 |
+
+### Look up a volume or file id
+
+```bash
+curl "http://localhost:9333/dir/lookup?volumeId=3"
+{"locations":[{"url":"localhost:8080","publicUrl":"localhost:8080"}]}
+```
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `volumeId` | volume id; a full `vid,fid` is accepted too | required |
+| `fileId` | like `volumeId`, but also returns a write JWT when security is on | empty |
+| `collection` | speeds up the lookup | empty |
+| `read` | `yes` generates a read JWT instead of a write JWT | empty |
+
+### Store a file in one call
+
+```bash
+curl -F file=@/home/chris/report.pdf "http://localhost:9333/submit?collection=turbo&replication=001"
+{"fileName":"report.pdf","fid":"3,01637037d6","fileUrl":"localhost:8080/3,01637037d6","size":43234,"eTag":"0x6c656..."}
+```
+
+`POST /submit` accepts multipart file data plus the `dir/assign` placement
+parameters (`count`, `collection`, `dataCenter`, `rack`, `replication`,
+`ttl`, `disk`), assigns a file id, uploads to the volume server, and returns
+the result.
+
+### Redirect to a file
+
+```bash
+curl -v "http://localhost:9333/3,01637037d6"
+```
+
+`GET /{fileId}` answers `308 Permanent Redirect` to a volume server holding
+the file, preserving the query string (e.g. image-resize parameters).
+
+### Cluster status
+
+```bash
+curl "http://localhost:9333/dir/status?pretty=y"   # full topology tree
+curl "http://localhost:9333/vol/status?pretty=y"   # every volume on every node
+curl "http://localhost:9333/collection/info?collection=turbo"
+curl "http://localhost:9333/collection/info?collection=turbo&detail=true"
+```
+
+`collection/info` returns aggregated `TotalSize`, `FileCount`, `UsedSize`,
+`VolumeCount`; `detail=true` splits them per volume layout.
+
+### Grow volumes
+
+```bash
+curl "http://localhost:9333/vol/grow?count=4&replication=001&collection=turbo&ttl=5d&disk=ssd&dataCenter=dc1&rack=rack1"
+{"count":4}
+```
+
+`count` is required; the placement parameters match `dir/assign`. One volume
+serves one write at a time, so pre-allocated volumes raise write concurrency.
+
+### Vacuum deleted space
+
+```bash
+curl "http://localhost:9333/vol/vacuum?garbageThreshold=0.4"
+```
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `garbageThreshold` | minimum deleted-bytes ratio before a volume is compacted | master `-garbageThreshold` (0.3) |
+
+Vacuuming makes a volume read-only, copies live needles to a new volume, and
+swaps it in.
+
+### Delete a collection
+
+```bash
+curl "http://localhost:9333/col/delete?collection=benchmark"
+```
+
+Deletes all volumes of the collection, including erasure-coded shards.
+`204 No Content` on success.
+
+### Health
+
+```bash
+curl -I "http://localhost:9333/healthz"     # liveness
+curl -I "http://localhost:9333/readyz"      # readiness
+curl "http://localhost:9333/"               # web UI
+```
+
+## Volume server API (port 8080)
+
+The volume server stores file content by file id. Clients normally get the
+volume URL from `dir/assign` or `dir/lookup`.
+
+### Upload
+
+```bash
+curl -F file=@/home/chris/myphoto.jpg "http://127.0.0.1:8080/3,01637037d6"
+{"name":"myphoto.jpg","size":43234,"eTag":"0x6c656...","mime":"image/jpeg","contentMd5":"..."}
+```
+
+PUT or POST the body (or a multipart `file` part) to `/{vid},{fid}`.
+`204 No Content` is returned when the content is unchanged. `?ts=<unix>`
+sets the stored modification time.
+
+### Read
+
+```bash
+curl "http://127.0.0.1:8080/3,01637037d6"
+curl "http://127.0.0.1:8080/3,01637037d6.jpg"        # sets Content-Type from the extension
+```
+
+Supports `Range` and `HEAD`. Image files can be resized server-side:
+
+| Parameter | Description |
+|-----------|-------------|
+| `width`, `height` | resize bounds in pixels |
+| `mode` | `fit` (contain) or `fill` (cover); omitted resizes to `width`/`height` |
+| `crop_x1`, `crop_y1`, `crop_x2`, `crop_y2` | explicit crop rectangle |
+| `cm` | `false` returns the chunk-manifest blob instead of resolving it |
+| `readDeleted` | `true` reads soft-deleted needles |
+| `collection` | passed through redirects for the right volume |
+
+### Delete
+
+```bash
+curl -X DELETE "http://127.0.0.1:8080/3,01637037d6"
+{"size":43234}
+```
+
+`?ts=<unix>` sets the deletion timestamp. Replicated volumes propagate the
+delete to every replica.
+
+### Status
+
+```bash
+curl "http://localhost:8080/status?pretty=y"  # disk and volume inventory
+curl -I "http://localhost:8080/healthz"       # liveness/readiness
+```
+
+`OPTIONS` preflights answer CORS headers. When `-port.public` differs from
+`-port`, the volume server opens a separate read-only public listener on
+that port; `-publicUrl` sets the address it advertises to clients.

+# SeaweedFS as an Apache CloudStack Object Storage Provider
+
+A CloudStack ObjectStore plugin that makes SeaweedFS a first-class object storage
+backend inside Apache CloudStack, alongside the existing MinIO and Ceph RGW
+providers. This is a collaboration with proIO (Swen), who builds private clouds on
+CloudStack and wants SeaweedFS as a storage option.
+
+## The request
+
+> We can only add MinIO and Ceph as object storage [in CloudStack] today. I want
+> to get SeaweedFS into this project... What we need is to build a provider which
+> does the communication between Cloudstack and SeaweedFS.
+
+This is **not** a SeaweedFS-side feature. The work lives in the Apache CloudStack
+repo (Java): a new plugin under `plugins/storage/object/seaweedfs/` that implements
+CloudStack's ObjectStore plugin framework and talks to SeaweedFS over its S3 and
+IAM APIs. SeaweedFS itself needs no changes for the core to work — its S3 API
+already covers every bucket operation CloudStack requires, and its IAM API covers
+user/credential management.
+
+## How the CloudStack ObjectStore framework works
+
+CloudStack 4.18+ introduced an Object Storage framework. An admin registers an
+object storage pool via `addObjectStoragePool` (URL + provider + credentials);
+tenants then create and manage buckets on it through CloudStack APIs. CloudStack
+manages pool and bucket lifecycle; the underlying provider handles the actual
+object protocol.
+
+A provider is a plugin module implementing three interfaces:
+
+### 1. `ObjectStoreProvider` — registration
+
+`MinIOObjectStoreProviderImpl` is the reference. It is a Spring `@Component` that:
+- Returns a provider name (`"MinIO"`)
+- Returns `DataStoreProviderType.OBJECT`
+- In `configure()`, injects the lifecycle and driver implementations and calls
+  `storeMgr.registerDriver(name, driver)`
+
+### 2. `ObjectStoreLifeCycle` — pool add/remove
+
+`MinIOObjectStoreLifeCycleImpl.initialize()` reads the URL, name, and
+`accesskey`/`secretkey` details from the `addObjectStoragePool` call, tests the
+connection by listing buckets, and persists an `ObjectStoreVO` via
+`ObjectStoreHelper`. The other methods (attachCluster/Host/Zone, maintain,
+deleteDataStore) are no-ops for object storage.
+
+### 3. `ObjectStoreDriver` — bucket + user operations
+
+`ObjectStoreDriver` (in `engine/storage/.../object/ObjectStoreDriver.java`) extends
+`DataStoreDriver` and defines the bucket/user contract. Every provider must
+implement:
+
+| Method | Purpose |
+| --- | --- |
+| `createBucket(Bucket, boolean objectLock)` | Create a bucket |
+| `listBuckets(long storeId)` | List all buckets |
+| `deleteBucket(BucketTO, long storeId)` | Delete a bucket |
+| `createUser(long accountId, long storeId)` | Provision a user + credentials for a CloudStack account |
+| `setBucketPolicy` / `getBucketPolicy` / `deleteBucketPolicy` | Bucket policy CRUD |
+| `setBucketEncryption` / `deleteBucketEncryption` | SSE config |
+| `setBucketVersioning` / `deleteBucketVersioning` | Versioning enable/suspend |
+| `setBucketQuota(BucketTO, long storeId, long size)` | Per-bucket quota |
+| `getAllBucketsUsage(long storeId)` | Usage map for billing/accounting |
+| `getBucketAcl` / `setBucketAcl` | ACLs (MinIO/Ceph return null / no-op) |
+
+`BaseObjectStoreDriverImpl` provides no-op defaults for the `DataStoreDriver`
+methods (`createAsync`, `deleteAsync`, `copyAsync`, `canCopy`, `resize`,
+`getTO`, `getStoreTO`), so object-store providers only implement the bucket/user
+methods above.
+
+## How the four existing providers differ (and where SeaweedFS lands)
+
+CloudStack ships four object-store providers. Three are relevant; the simulator
+is a test stub.
+
+| Concern | MinIO | Ceph RGW | Cloudian HyperStore | SeaweedFS |
+| --- | --- | --- | --- | --- |
+| Bucket CRUD | `MinioClient` (S3) | `AmazonS3` (AWS SDK v1) | `AmazonS3` (AWS SDK v1) | `AmazonS3` (AWS SDK v1) |
+| Bucket policy | `MinioClient` | `AmazonS3` | `AmazonS3` | `AmazonS3` |
+| Versioning | `MinioClient` | `AmazonS3` | `AmazonS3` | `AmazonS3` |
+| Encryption | `MinioClient` | not implemented | `AmazonS3` | `AmazonS3` |
+| **User creation** | `MinioAdminClient` | `RgwAdmin` | **`AmazonIdentityManagement`** | **`AmazonIdentityManagement`** |
+| **Per-bucket quota** | `MinioAdminClient` | `RgwAdmin` | **not supported** (throws) | **S3 extension** (`PUT /{bucket}?seaweedfs-quota`, SigV4, `s3:PutBucketQuota`) |
+| **Usage reporting** | `MinioAdminClient` | `RgwAdmin` | Cloudian admin API | S3 `ListObjectsV2` (MVP); Prometheus / SOSAPI `capacity.xml` (recommended) |
+
+**Cloudian HyperStore is the direct precedent.** It is an S3-compatible store
+that, like SeaweedFS, manages users via the **standard AWS IAM API** using the
+AWS IAM Java SDK (`com.amazonaws.services.identitymanagement`). Its driver
+(`CloudianHyperStoreObjectStoreDriverImpl`) and util
+(`CloudianHyperStoreUtil`) are the template this design follows almost line for
+line. Cloudian even validates the quota limitation the same way this design
+proposes for the MVP: `setBucketQuota` throws for any non-zero size and only
+accepts `0` (no quota).
+
+The SeaweedFS plugin is therefore a **simpler Cloudian** — same AWS S3 + IAM SDK
+clients, same store-details keys (`s3Url`, `iamUrl`, `accesskey`, `secretkey`),
+same IAM-user-with-restricted-policy pattern, but with no proprietary admin
+client at all (Cloudian has its own `CloudianClient` for its admin API; SeaweedFS
+needs only S3 + IAM). For quota, the plugin uses a narrow SeaweedFS S3 extension
+(see below); for usage reporting, it falls back to S3 `ListObjectsV2` in the MVP
+and recommends Prometheus or SOSAPI `capacity.xml` for production scale.
+
+### Quota via the S3 `?seaweedfs-quota` extension
+
+SeaweedFS supports bucket quota natively (server-side enforcement via a
+read-only flag when usage exceeds the limit). Rather than exposing the broad
+admin REST API (which would require a global bearer token and grant cluster-wide
+admin access), the integration uses a **narrow, scoped S3 subresource**:
+
+- `PUT /{bucket}?seaweedfs-quota` — set bucket quota (IAM permission `s3:PutBucketQuota`)
+- `GET /{bucket}?seaweedfs-quota` — get bucket quota (IAM permission `s3:GetBucketQuota`)
+
+**PUT request body** (JSON):
+```json
+{"quota_size": 100, "quota_unit": "GB", "quota_enabled": true}
+```
+
+**GET response body** (JSON):
+```json
+{"quota_size": 107374182400, "quota_unit": "B", "quota_enabled": true}
+```
+
+Note: GET always returns `quota_unit: "B"` and the absolute byte count, not
+the original unit. A disabled-but-retained quota returns a positive
+`quota_size` with `quota_enabled: false`.
+
+Quota is stored on the bucket's filer entry (positive = enabled, negative =
+disabled but retained, zero = no quota), matching the existing admin REST API
+behavior. When quota is cleared, the bucket's read-only flag is also lifted.
+
+**Authentication** uses the existing S3 SigV4 flow — no new global secret is
+needed. The CloudStack service credential (the `accesskey`/`secretkey` on the
+object store) is the admin credential used for all driver operations: bucket
+CRUD, IAM user provisioning, and quota management. It must have broad S3 and
+IAM permissions. The per-account IAM users created by `createUser` are the
+ones with restricted permissions (full S3 access except bucket
+creation/deletion). A future hardening could split quota management onto a
+separate credential scoped to only `s3:PutBucketQuota`/`s3:GetBucketQuota`,
+but the MVP uses the single admin credential for simplicity, matching how
+the MinIO and Ceph providers work.
+
+The plugin's `setBucketQuota` signs and sends the `PUT /{bucket}?seaweedfs-quota`
+request using the AWS SDK v1 `AWSS3V4Signer` for SigV4 signing, then sends the
+signed request via `java.net.http.HttpClient` (the AWS S3 SDK doesn't natively
+support custom subresources, so we sign manually and send the request
+ourselves). The `seaweedfs-quota` query parameter is included in the signed
+canonical query string.
+
+### Usage reporting
+
+`getAllBucketsUsage` must return a `Map<String, Long>` of bucket name → size.
+MinIO uses `MinioAdminClient.getDataUsageInfo`; Ceph uses
+`RgwAdmin.listBucketInfo`. SeaweedFS has no admin rollup endpoint, so the MVP
+plugin computes it by listing buckets and summing object sizes via S3
+`ListObjectsV2` — expensive for large stores.
+
+For production scale, SeaweedFS already exposes per-bucket size in:
+- **Prometheus metrics** (`bucket_size_bytes` gauge, refreshed every minute)
+- **SOSAPI `capacity.xml`** (reports capacity, available space, and usage
+  through the S3 endpoint)
+
+Operators should consume one of those instead of S3 list-based aggregation for
+large deployments. The MVP's list-based approach is correct but slow; flag it as
+a known limitation.
+
+## SeaweedFS API surface (what the plugin relies on)
+
+SeaweedFS exposes two relevant APIs, both AWS-compatible:
+
+### S3 API (`weed s3`)
+Full S3-compatible surface. Confirmed against the SeaweedFS S3 wiki and code:
+- `CreateBucket`, `HeadBucket`, `ListBuckets`, `DeleteBucket`
+- `PutBucketPolicy`, `GetBucketPolicy`, `DeleteBucketPolicy`
+- `PutBucketVersioning` (Enabled / Suspended), `GetBucketVersioning`
+- `PutBucketEncryption`, `GetBucketEncryption`, `DeleteBucketEncryption`
+- `PutBucketAcl`, `GetBucketAcl`
+- `ListObjectsV2`, `HeadObject`, `GetObject`, `PutObject`, `DeleteObject`
+- Bucket quota via extended attributes / `s3.bucket.quota` (enforced server-side,
+  surfaced as a read-only state when exceeded — see PR #10224)
+
+### IAM API (`weed iam` / `iamapi`)
+AWS IAM-compatible REST endpoints, implemented in `weed/iamapi/`. Confirmed by
+the test suite which uses the **AWS IAM SDK** (`aws-sdk-go/service/iam`) against
+the same handlers CloudStack would call:
+- `CreateUser`, `DeleteUser`, `ListUsers`, `GetUser`
+- `CreateAccessKey`, `DeleteAccessKey`, `ListAccessKeys`
+- `PutUserPolicy`, `GetUserPolicy`, `DeleteUserPolicy`
+- `AttachUserPolicy`, `ListAttachedUserPolicies`
+
+This means the CloudStack plugin can manage SeaweedFS users with the **AWS IAM
+Java SDK** (`com.amazonaws.services.identitymanagement.AmazonIdentityManagement`),
+exactly the way the AWS IAM Go SDK is used in SeaweedFS's own tests. No proprietary
+admin client is needed. **Cloudian HyperStore already does exactly this** in the
+CloudStack tree — the SeaweedFS plugin follows the same pattern.
+
+## Design
+
+### Module layout
+
+New CloudStack plugin module, mirroring `plugins/storage/object/cloudian/`
+(the closest precedent — same AWS S3 + IAM SDK approach):
+
+```
+plugins/storage/object/seaweedfs/
+  pom.xml
+  src/main/java/org/apache/cloudstack/storage/datastore/
+    driver/SeaweedFSObjectStoreDriverImpl.java
+    lifecycle/SeaweedFSObjectStoreLifeCycleImpl.java
+    provider/SeaweedFSObjectStoreProviderImpl.java
+    util/SeaweedFSObjectStoreUtil.java
+  src/test/java/org/apache/cloudstack/storage/datastore/
+    driver/SeaweedFSObjectStoreDriverImplTest.java
+    provider/SeaweedFSObjectStoreProviderImplTest.java
+  src/main/resources/META-INF/cloudstack/storage-object-seaweedfs/
+    module.properties
+    spring-storage-object-seaweedfs-context.xml
+```
+
+### `SeaweedFSObjectStoreProviderImpl`
+
+Direct copy of `MinIOObjectStoreProviderImpl` with `providerName = "SeaweedFS"`,
+injecting the SeaweedFS lifecycle and driver. Registers via
+`storeMgr.registerDriver`.
+
+### `SeaweedFSObjectStoreLifeCycleImpl`
+
+Copy of `MinIOObjectStoreLifeCycleImpl`. `initialize()` reads `url`, `name`,
+`accesskey`, `secretkey` from the `addObjectStoragePool` details map, tests the
+connection by calling `AmazonS3.listBuckets()` against the SeaweedFS S3 endpoint,
+and persists the `ObjectStoreVO`. No proprietary client needed — the AWS S3 SDK
+is enough for the health check.
+
+### `SeaweedFSObjectStoreDriverImpl`
+
+The substantive class. Uses two AWS SDK v1 clients (same dependency Ceph already
+pulls in, so no new CloudStack dependency):
+
+- `AmazonS3` for bucket operations (path-style, endpoint-pinned, `us-east-1`
+  region placeholder — same as Ceph's `getS3Client`)
+- `AmazonIdentityManagement` for user/credential operations, pointed at the
+  SeaweedFS IAM endpoint
+
+#### Bucket operations — straightforward S3
+
+| Interface method | Implementation |
+| --- | --- |
+| `createBucket` | `s3.createBucket(name)`; reject if `doesBucketExistV2`; persist access/secret key + URL on `BucketVO` (same as Ceph) |
+| `listBuckets` | `s3.listBuckets()` → wrap as `BucketObject` (same as Ceph) |
+| `deleteBucket` | `s3.deleteBucket(name)` (same as Ceph) |
+| `setBucketPolicy` | `s3.setBucketPolicy(...)` with the same public/private JSON the MinIO/Ceph drivers build |
+| `getBucketPolicy` / `deleteBucketPolicy` | `s3.getBucketPolicy` / `s3.deleteBucketPolicy` |
+| `setBucketVersioning` | `s3.setBucketVersioningConfiguration(Enabled)` |
+| `deleteBucketVersioning` | `s3.setBucketVersioningConfiguration(Suspended)` |
+| `setBucketEncryption` | `s3.setBucketEncryptionConfiguration(SSE-S3 rule)` |
+| `deleteBucketEncryption` | `s3.deleteBucketEncryptionConfiguration` |
+| `getBucketAcl` / `setBucketAcl` | no-op / null (same as MinIO and Ceph) |
+
+#### User creation — the key difference
+
+MinIO calls `MinioAdminClient.addUser`; Ceph calls `RgwAdmin.createUser`. SeaweedFS
+exposes the standard AWS IAM API, so the plugin calls:
+
+```java
+AmazonIdentityManagement iam = getIamClient(storeId);
+String userName = "acs-" + account.getUuid();
+
+// CreateUser (idempotent — check GetUser first, like Ceph does)
+iam.createUser(new CreateUserRequest(userName));
+
+// CreateAccessKey → returns the access key + secret key to persist
+CreateAccessKeyResult result = iam.createAccessKey(
+    new CreateAccessKeyRequest().withUserName(userName));
+AccessKey key = result.getAccessKey();
+
+// Persist per-account, same pattern as Ceph's CEPH_ACCESS_KEY/CEPH_SECRET_KEY
+details.put(SEAWEEDFS_ACCESS_KEY, key.getAccessKeyId());
+details.put(SEAWEEDFS_SECRET_KEY, key.getSecretAccessKey());
+_accountDetailsDao.persist(accountId, details);
+```
+
+This is the cleanest mapping of the three providers: no proprietary admin client,
+just the AWS IAM SDK that CloudStack already has access to. The IAM endpoint URL
+is provided as `iamUrl` in the store details. If `iamUrl` is omitted, the driver
+defaults it to `s3Url` — SeaweedFS registers its embedded IAM API at `POST /` on
+the same S3 endpoint (`UnifiedPostHandler` in `s3api_server.go`), so the IAM
+endpoint is the same as the S3 endpoint unless the deployment runs a separate
+`weed iam` server.
+
+#### Bucket quota — S3 `?seaweedfs-quota` extension
+
+This is the one genuine gap. MinIO and Ceph both have an admin API to set a
+per-bucket quota that the backend enforces. SeaweedFS enforces bucket quota
+server-side, but the configuration path was **not exposed over a standard S3 or
+IAM API** — it was only set via the admin REST API or shell commands.
+
+The integration adds a **narrow S3 subresource** to SeaweedFS:
+- `PUT /{bucket}?seaweedfs-quota` — set bucket quota (IAM permission `s3:PutBucketQuota`)
+- `GET /{bucket}?seaweedfs-quota` — get bucket quota (IAM permission `s3:GetBucketQuota`)
+
+This is implemented in SeaweedFS PR #11279. It uses SigV4 authentication and
+dedicated IAM permissions, so the CloudStack service credential can be scoped
+to quota management only — no global admin token, no cluster-wide admin access.
+The enforcement already exists (PR #10224); this PR only adds the HTTP
+configuration surface.
+
+An earlier approach (PR #11278, closed) added bearer-token auth to the broad
+admin REST API. After review, that was unnecessary for this integration —
+static S3 config plus standard S3 APIs plus one scoped quota mutation API is
+sufficient and far safer.
+
+> **Note on AWS tools compatibility.** `?seaweedfs-quota` is a SeaweedFS-specific
+> S3 subresource, not part of the AWS S3 API. Standard AWS tools (`aws s3api`,
+> `s3cmd`, `rclone`) cannot call it directly. This is the same limitation MinIO
+> and Ceph have — MinIO quota lives behind a separate admin API (`mc admin
+> bucket quota`), and Ceph quota lives behind the Admin Ops API
+> (`radosgw-admin quota set`). Neither is callable via `aws s3api` either.
+> SeaweedFS's approach is the closest to standard S3 because it uses the same
+> endpoint and same SigV4 credentials, just with a custom query parameter.
+> Interactive quota management remains available via `weed shell`; the S3
+> extension exists for programmatic integration (CloudStack) where the
+> integrator can sign SigV4 requests but cannot run shell commands.
+
+#### Usage reporting
+
+`getAllBucketsUsage` must return a `Map<String, Long>` of bucket name → size.
+MinIO uses `MinioAdminClient.getDataUsageInfo`; Ceph uses
+`RgwAdmin.listBucketInfo`. SeaweedFS has no admin rollup endpoint, so the MVP
+plugin computes it by listing buckets and summing object sizes via S3
+`ListObjectsV2` — expensive for large stores. Better options exist in
+SeaweedFS already:
+- **Prometheus metrics** (`bucket_size_bytes` gauge, refreshed every minute)
+- **SOSAPI `capacity.xml`** (reports capacity, available space, and usage
+  through the S3 endpoint — note: the current "return zero on backend error"
+  behavior should be validated before using it for billing)
+
+For the MVP, `listBuckets` + per-bucket size via the S3 API is correct but slow;
+flag it as a known limitation. Operators should consume Prometheus or SOSAPI
+for production-scale usage reporting.
+
+### Spring wiring
+
+`spring-storage-object-seaweedfs-context.xml` registers the provider bean,
+identical to the MinIO one. `module.properties` sets
+`name=storage-object-seaweedfs`, `parent=storage`.
+
+### `pom.xml`
+
+Depends on `aws-java-sdk-s3` and `aws-java-sdk-iam` — both already in the
+CloudStack dependency tree (Ceph uses the S3 SDK; the IAM SDK is the standard AWS
+bundle). No new third-party dependency, unlike MinIO which pulls in the MinIO
+Java client.
+
+## What changes on the SeaweedFS side
+
+**One narrow S3 extension is required for quota management.** SeaweedFS PR #11279
+adds the `?seaweedfs-quota` S3 subresource:
+
+- `PUT /{bucket}?seaweedfs-quota` — set bucket quota (IAM permission `s3:PutBucketQuota`)
+- `GET /{bucket}?seaweedfs-quota` — get bucket quota (IAM permission `s3:GetBucketQuota`)
+
+This is authenticated via standard S3 SigV4 and authorized via dedicated IAM
+permissions, so no global admin token is needed. The enforcement already exists
+(PR #10224); this PR only adds the HTTP configuration surface.
+
+One follow-up improvement on the SeaweedFS side would close the usage reporting
+gap:
+
+1. **Validate SOSAPI `capacity.xml` usage calculation** — the current "return
+   zero on backend error" behavior should be validated before using it for
+   billing. If reliable, CloudStack can consume it directly instead of
+   list-based aggregation.
+
+## Open questions for proIO / Swen
+
+1. **IAM endpoint path.** ~~Where does `weed iam` listen relative to the S3
+   endpoint in a typical proIO deployment?~~ **Resolved.** SeaweedFS registers
+   its embedded IAM API at `POST /` on the same S3 endpoint
+   (`UnifiedPostHandler`), so the driver defaults `iamUrl` to `s3Url`. A
+   separate `iamUrl` is only needed if the deployment runs a standalone
+   `weed iam` server on a different host/port.
+2. **Quota requirements.** Do proIO's customers need server-enforced per-bucket
+   quotas, or is CloudStack-side accounting sufficient for the first release?
+   The `?seaweedfs-quota` S3 extension (PR #11279) provides server-enforced
+   quotas via a scoped credential; this is the recommended path.
+3. **Object Lock.** `createBucket` takes an `objectLock` boolean. MinIO supports
+   it; Ceph ignores it. SeaweedFS has Object Lock support. Should the plugin pass
+   it through?
+4. **Contribution model.** Does proIO want to submit the PR to
+   `apache/cloudstack` themselves (with SeaweedFS maintainers as reviewers), or
+   the reverse? Apache CloudStack requires an ICLA for non-trivial contributions.

+# Lance Catalog for SeaweedFS
+
+A second catalog surface next to the Iceberg REST catalog, speaking the Lance Namespace
+REST spec, over the same table buckets and the same filer.
+
+## Why
+
+Gravitino 1.1 added a Lance REST service and 1.3 ships it as a standalone server; Lakekeeper
+added Lance in the same window by a completely different route. That is the useful signal:
+two unrelated catalogs decided independently that Lance had to be first-class, not a niche.
+The client side is already there — `lance-spark` (`LanceNamespaceSparkCatalog`
+with `impl=rest`), `lance-ray`, and the generated Python/Java/Rust clients all talk the same
+OpenAPI. Implementing the spec means those engines work against SeaweedFS with no
+SeaweedFS-specific code on the client.
+
+The second reason is that Gravitino's own documentation names the gap it cannot close:
+DuckDB, pandas and DataFusion "do not support Lance REST natively yet" and have to fetch a
+location from the catalog and then open the dataset directly. Gravitino cannot help there,
+because it does not own the storage. SeaweedFS does. That is the whole design opportunity
+below.
+
+## Prior art: three families
+
+Upstream lists twelve catalog implementations, and they fall into three shapes. Knowing
+which one we are building matters more than any individual API decision.
+
+**1. Storage-native, no service.** The Lance Directory Catalog. V1 is a directory listing
+where every `<name>.lance/` child of a prefix is a table; V2 adds a `__manifest` table —
+itself a Lance table — holding `object_id`/`object_type`/`location` rows, with nested
+namespaces, hash-prefixed table directories, and optional managed versioning. No server, no
+credentials, no governance. This is the floor every other implementation has to beat.
+
+**2. Protocol-native server.** Someone implements the Lance Namespace REST OpenAPI and
+clients connect with `impl=rest`. Gravitino is the only one of the twelve that does this,
+and it is what this design proposes.
+
+**3. Client-side adapters onto an existing catalog.** Nine of the twelve. The Lance client
+translates namespace operations into whatever the backing catalog already speaks: Apache
+Polaris, Unity Catalog, AWS Glue, Hive Metastore v2 and v3, Google BigLake, Dataproc,
+Microsoft OneLake — and Apache Iceberg REST. Two flavors:
+
+- Catalogs with a real non-Iceberg table concept mark the format directly. Polaris uses its
+  Generic Table API with `format = lance`; Unity uses an `EXTERNAL` table with
+  `table_type=lance` in properties and the path in `storage_location`; Glue uses
+  `EXTERNAL_TABLE` plus `table_type=lance` in `Parameters`, path in
+  `StorageDescriptor.Location`.
+- Catalogs with no such concept fake one. The Iceberg REST adapter registers **a regular
+  Iceberg table with a dummy schema — a single nullable string column named `dummy`** —
+  carrying the property `table_type=lance`, and treats the Iceberg table location as the
+  Lance dataset root.
+
+Every adapter in family 3 lands in the same place: `DeclareTable`/`ListTables`/
+`DescribeTable`/`DeregisterTable` only, `DropNamespace` in RESTRICT mode only,
+`load_detailed_metadata=false` only, and `managed_versioning=false`. They are a name-to-
+location map and nothing more.
+
+Lakekeeper is the instructive outlier. It has the same generic-table concept Polaris has,
+but no upstream adapter exists for it — there is no `lance-namespace` reference anywhere in
+its repository and no page for it in the supported-catalogs list. So Polaris's generic tables
+are reachable from a stock Lance client and Lakekeeper's are not, despite being the same
+idea. Shipping the concept is not the same as shipping the integration.
+
+## Gravitino and Lakekeeper: the two opposite bets
+
+Both shipped Lance support in the same window and did not build the same thing.
+
+**Gravitino implements the protocol.** Its `lance/` module serves the Lance Namespace REST
+spec on its own port (`:9101/lance`), so stock `lance-spark` and `lance-ray` connect with
+`impl=rest` and no vendor-specific client. The cost is governance: storage credentials are
+static properties on the catalog (`lance.storage.access_key_id`, `secret_access_key`,
+`endpoint`, `region`, `allow_http`), optionally overridden per table, handed to the engine
+as-is. No STS, no expiry, no per-table scoping.
+
+**Lakekeeper refuses the protocol and governs the object instead.** There is no
+`lance-namespace` anywhere in the repository; Lance arrived in 0.13.0 (2026-06-30, issue
+#1673 `Generic Table API with Lance`) as one `format` string on a Lakekeeper-native Generic
+Table API:
+
+```
+POST/GET/DELETE /lakekeeper/v1/{prefix}/namespaces/{ns}/generic-tables[/{table}]
+GET             /lakekeeper/v1/{prefix}/namespaces/{ns}/generic-tables/{table}/credentials
+POST            /lakekeeper/v1/{prefix}/generic-tables/rename
+```
+
+`format` is opaque, `schema` and `statistics` are stored but never validated, and the
+catalog writes no format-specific metadata — engines go straight to the location. In
+exchange Lance tables get everything Iceberg tables get: STS-vended prefix-scoped
+credentials, OpenFGA per-action permissions (16 actions), soft-delete with undrop, a
+protection flag, rename, pagination, and name uniqueness across Iceberg tables, views and
+generic tables in one namespace. The price is that no stock Lance client can talk to it —
+you need `pylakekeeper`, which exists mainly to translate vended credentials into
+`lance_storage_options`.
+
+So: protocol fidelity and weak governance, or strong governance and client lock-in. Both
+documented their limit honestly, and it is the same limit. Lakekeeper's capability table
+says it outright — "Commit coordination: the catalog does not arbitrate writes — engines
+write directly." Gravitino does not claim it either. Neither of them coordinates a Lance
+commit, which is exactly the thing a store can do and a control plane cannot.
+
+We do not have to choose. Serve the Lance protocol natively the way Gravitino does, over
+the `s3tables` entries that already carry ARNs, policies, tags and maintenance config, and
+the governance comes from the layer underneath rather than from a proprietary API on top.
+That is only available to us because we are the store, which is also what makes the third
+option — arbitrating the commit — available.
+
+## We are probably already a Lance catalog, and that is a problem
+
+The Iceberg REST adapter does not care whose Iceberg catalog it is talking to. It needs
+`/v1/config?warehouse=`, `/v1/{prefix}/namespaces`, `/v1/{prefix}/namespaces/{ns}/tables`
+and unit-separator (`\x1F`) multi-level namespaces. We serve all of those, and
+`parseNamespace` in `weed/s3api/iceberg/utils.go:22` already splits on `\x1F`. So a stock
+Lance client pointed at our Iceberg catalog on :8181 with the Iceberg impl should already
+create, list, describe and deregister Lance tables today, with no SeaweedFS change at all.
+
+That is worth testing before writing a line of the design above, for two reasons. It is a
+free baseline — and possibly a free announcement. And it is a data-loss hazard.
+
+A Lance table registered this way is an Iceberg table whose metadata references no data
+files, sitting on top of a Lance dataset that uses `data/` for its fragments — the same
+subdirectory name Iceberg uses. The maintenance worker's orphan cleaner walks exactly
+`<table>/metadata` and `<table>/data`, and deletes every file not referenced by a snapshot
+and older than `orphan_older_than_hours`
+(`weed/worker/tasks/iceberg/operations.go:331`, default 72). Against an adapter-registered
+Lance table, every fragment is unreferenced by construction. Run maintenance and the
+dataset is deleted.
+
+Maintenance is disabled by default (`handler.go:334`), so this is a latent hazard rather
+than a live one: it needs an operator to enable Iceberg maintenance on a bucket that also
+holds adapter-registered Lance tables. But it costs nothing to close — detection should
+skip any table carrying a non-Iceberg format marker (`table_type` property, or
+`Format != "ICEBERG"` once the format field is honest), and that guard is worth landing on
+its own regardless of whether the rest of this design ever gets built. It is the same
+"catalog-only, no maintenance" marker the generic-format question needs.
+
+## Where we differ from Gravitino
+
+Gravitino is a metadata service in front of somebody else's object store:
+
+```
+  Spark / Ray                  Spark / Ray / pandas / duckdb
+      |                              |
+  Lance REST                    Lance REST          (direct S3)
+      |                              |                   |
+  Gravitino                     SeaweedFS S3 gateway ----+
+      |                              |
+   S3 keys handed out           SeaweedFS filer + volumes
+      |
+  somebody else's S3
+```
+
+It resolves a name to a location plus `lance.storage.*` credentials, and steps out of the
+way. Everything a Lance table actually is — `_versions/`, `data/`, `_indices/` — is opaque
+to it.
+
+We are the store. Three things follow that Gravitino cannot do:
+
+1. The catalog and a plain directory listing can be made to agree, so a client with no
+   catalog at all still sees the right tables.
+2. `_versions/` is a filer directory listing, not an object-store `LIST`. Version history
+   is cheap and can back the admin UI.
+3. We can offer a genuinely atomic commit reservation. Lance's commit protocol needs
+   put-if-not-exists; our S3 layer does not currently provide one (see
+   [Commit safety](#commit-safety)). The filer does.
+
+## Placement
+
+The Iceberg catalog is a thin HTTP shell over `s3tables.Manager`; the storage work lives in
+`weed/s3api/s3tables`. Table buckets live under `TablesPath = s3_constants.DefaultBucketsPath`,
+i.e. the same filer tree the S3 gateway serves, so `s3://bucket/ns/table/` is simultaneously
+a catalog entry and an S3 prefix. Catalog entries are filer directories carrying `s3tables.*`
+extended attributes. `Table.Format` already exists and is hard-checked against `"ICEBERG"`
+in `weed/s3api/s3tables/handler_table.go:48`.
+
+So:
+
+```
+weed/s3api/lance/          new: HTTP surface, id codec, error model
+weed/s3api/s3tables/       extended: Format "LANCE", lance state xattr, version entries
+weed/command/s3.go         new: -port.lance (default 9101), startLanceServer
+```
+
+`Format: "LANCE"` on the table entry is the whole storage-model change for phase 1.
+Everything else — namespaces, ARNs, policies, tags, ownership — is shared verbatim.
+
+```
+                        s3tables.Manager (filer)
+                                 |

+```
+
+## Identifier mapping
+
+Lance identifiers are `["ns", ..., "table"]`, encoded in the URL as a single string joined
+by a delimiter that defaults to `$`. The delimiter alone means the root namespace, so
+`/v1/namespace/$/list` lists the root's children.
+
+Iceberg had to invent a warehouse selector because its identifier is flat and every table
+bucket is a separate catalog. Lance does not need that — its identifier is already
+hierarchical, and Gravitino uses exactly three levels (`["lance_catalog", "sales", "orders"]`).
+That maps onto us without inventing anything:
+
+```
+  $                            root      -> list of table buckets
+  $analytics                   level 1   -> a table bucket
+  $analytics$sales             level 2   -> a namespace in that bucket
+  $analytics$sales$orders      table
+```
+
+`spark.sql.catalog.lance.parent = analytics` then makes `sales.orders` resolve, which is the
+same shape Gravitino's Spark example uses.
+
+Levels 2..N join into one `s3tables` namespace with `.`, matching what the Iceberg catalog
+already does with `flattenNamespacePath`. The flattened form is only the directory name —
+`namespaceMetadata.Namespace []string` in the xattr keeps the authoritative parts, so the
+mapping stays invertible even though `.` is a legal character inside a namespace part.
+Reject `$` in any name part with `InvalidInput`; our charsets already exclude it, so no
+escaping scheme is needed.
+
+Root-level `ListNamespaces` returning table buckets means an unauthenticated or
+broadly-scoped caller can enumerate buckets. Filter it through the same
+`s3tables/permissions.go` check `ListTableBuckets` uses, not a separate path.
+
+`CreateNamespace` on a one-part identifier creates a table bucket, and it does so only if
+the caller is permitted to — the namespace never creates a bucket as a side effect of
+creating something inside it. A table bucket is a tenant resource with its own policy, ARN
+and lifecycle, and conjuring one because a client said `CREATE SCHEMA` is a privilege
+escalation dressed as a convenience. Lakekeeper draws the same line explicitly: its client
+creates tables, not warehouses.
+
+## Storage layout
+
+Lay tables out as:
+
+```
+s3://<table-bucket>/<flattened-namespace>/<table>/
+    data/
+    _versions/
+    _indices/
+```
+
+**Built without the `.lance` suffix this design originally proposed.** The suffix would have
+made every namespace prefix a valid Lance Directory Catalog V1 root, since V1 recognises a
+table by exactly that naming. It does not survive contact with the storage layer: the
+catalog entry *is* the dataset directory, `validateTableName` excludes `.` from the charset,
+and a suffixed entry name would leak into ARNs, policy documents and the S3 Tables API,
+where the same table would answer to two different names. Making `GetTablePath` format-aware
+instead spreads an "unless it is Lance" branch through code that has no business knowing —
+the exact cross-cutting cost this design rejects family 3 for.
+
+So one name, one directory. What survives is direct access by URI, which is the larger half
+of the story and needs no naming convention at all:
+
+```python
+# with the catalog
+spark.sql("SELECT * FROM lance.sales.orders")
+
+# without it, same bytes
+lance.dataset("s3://analytics/sales/orders")
+```
+
+DuckDB, pandas and DataFusion still reach the data with no catalog running, which is the gap
+Gravitino's documentation admits to. What they no longer get for free is *enumeration* — a
+directory-catalog client pointed at the namespace prefix will not list these as tables. If
+that turns out to matter, the cheapest fix is a repair-style tool that materialises `.lance`
+aliases, not a rename of the catalog entry.
+
+Note also that the directory catalog's own V2 mode puts child-namespace tables in
+`<hash>_<ns$table>` directories at the root and creates no physical subdirectories for
+namespaces, so full directory-catalog fidelity was never on offer anyway. We are a
+server-backed catalog; the human-readable prefix layout is worth more than partial V1
+lookalike behaviour.
+
+## The table bucket was not a neutral container
+
+This design assumed a table bucket is a place to put a table's files. It is
+not: `validateTableBucketObjectPath` runs on every S3 write into one and
+validated the path against Iceberg's layout, so a Lance client got 403 on
+`data/*.lance`, on `_versions/`, and on `_transactions/` — a directory Lance
+writes that neither the spec documentation nor this design anticipated. Nothing
+about the catalog worked end to end until that changed.
+
+The layout guard now admits the union of what the supported formats write, and
+treats any underscore-prefixed top-level directory as belonging to the format,
+checking only that the path stays inside the table. Enumerating Lance's
+internal directories by name is exactly the mistake that missed
+`_transactions`. Iceberg writes none of them, so it loses nothing.
+
+Found by pointing the real Python client at a running gateway, not by reading
+the spec. Worth remembering for the next format: the premise to check first is
+whether the storage layer will accept its files at all.
+
+## Table lifecycle
+
+Lance has three table states, and the spec pins them to marker files:
+
+| State | Marker | Created by | Visible in ListTables |
+| --- | --- | --- | --- |
+| declared | `.lance-reserved` | `DeclareTable` | yes, when `include_declared=true` |
+| created | `_versions/` present | client writes, or `CreateTable` | yes |
+| deregistered | `.lance-deregistered` | `DeregisterTable` | no; data preserved |
+
+Record the state in an xattr (`s3tables.lanceState`) on the catalog entry *and* write the
+marker file into the table directory. The xattr is what the catalog reads; the marker is
+what keeps a directory-catalog client honest. Dual-write is the price of the interop claim
+above, and it is one extra filer write on three rarely-called operations.
+
+`DeclareTable` is the operation `lance-spark` actually calls on `CREATE TABLE` (it replaced
+the legacy `create-empty`), so it is not optional in practice even though the spec marks
+only a subset as required.
+
+`DeregisterTable` preserving data is the same shape as our Iceberg rename, where the catalog
+entry moves and the data stays put — reuse `TableDataDirFromMetadataLocation`'s idea rather
+than re-deriving the data path from the catalog name.
+
+## Commit safety
+
+This is the part I got wrong, and the correction removed a feature rather than adding one.
+
+Lance commits a version by writing `_versions/{v}.manifest` with put-if-not-exists: exactly
+one writer is supposed to win, and the loser rebases. In lance 10 that path is not optional
+and needs nothing bolted on — `commit_handler_from_url` hands every `s3://` dataset a
+`ConditionalPutCommitHandler`, which calls `put_opts` with `PutMode::Create`, which
+object_store's S3 backend sends as `If-None-Match: *`.
+
+I originally read our gateway as evaluating that header check-then-act, and designed around
+it. That was already out of date. `buildWriteCondition`
+(`weed/s3api/s3api_object_routed_write.go`) reduces `If-None-Match: *` to a filer
+`WriteCondition{IF_NOT_EXISTS}`, and `putToFiler` routes the create to the object's owner
+filer, which evaluates the precondition under its per-path lock; when routing is not
+available it falls back to the object write lock, which evaluates it under the lock too.
+Either way it is atomic. Sixteen concurrent writers of the same fresh key get one 200 and
+fifteen 412s, repeatedly.
+
+So the store already has the primitive Lance needs, cluster-wide, for every conditional-PUT
+client and not just this one.
+
+### What that removed
+
+An earlier draft of this design offered the catalog as an **external manifest store**:
+`managed_versioning: true` plus `CreateTableVersion` and friends, with the reserve step as a
+filer `CreateEntry` with `o_excl`. It was implemented, tested, and shipped behind a default-off
+flag — and it should not exist.
+
+- It solves a problem this store does not have. The spec offers that path for stores that
+  cannot order commits themselves.
+- It moves a table's version history out of the dataset and into the catalog, so a reader
+  that does not go through this namespace no longer sees the whole picture. That is a real
+  cost paid for nothing.
+- lance 10 cannot even use it past the first commit: `NamespaceManifestStore::put_if_not_exists`
+  answers "put_if_not_exists is not supported for namespace-backed stores", which is exactly
+  what a second `append` needs.
+
+The version operations now answer `Unsupported` alongside the other operations the catalog
+does not serve, and `managed_versioning` is answered `false`. The property they were
+protecting is covered instead by a test that races eight writers at the manifest key through
+S3 and asserts one wins — testing the path Lance actually takes.
+
+## Credential vending
+
+Iceberg needed a header (`X-Iceberg-Access-Delegation: vended-credentials`) and a bespoke
+response shape. Lance has it in the spec: `vend_credentials: true` on the request,
+`storage_options` on the response, with `expires_at_millis` as the well-known expiry key.
+
+Reuse the existing vendor interface unchanged — `iceberg.CredentialVendor` /
+`STSService.AssumeRoleForPrincipal` scoped to the table prefix (#10777) — and map its output
+to the storage options Lance passes through to `object_store`:
+
+```
+aws_access_key_id, aws_secret_access_key, aws_session_token,
+aws_region, aws_endpoint, allow_http, expires_at_millis
+```
+
+Those are the names `pylakekeeper` emits as `lance_storage_options`, which is the shape
+Lakekeeper's tested S3 path actually feeds to Lance. `object_store` also accepts the
+un-prefixed aliases (`endpoint`, `region`) that the directory catalog's `storage.` prefix
+strips down to and that Gravitino's `lance.storage.endpoint` resolves to, but the `aws_`
+forms are the ones with a tested integration behind them, so emit those. `aws_endpoint`
+should come from `deriveS3AdvertisedEndpoint()`, the same source the Iceberg `FileIO` config
+uses, and `allow_http` must be set when that endpoint is plain HTTP or every read fails with
+a TLS error that looks like a credential problem — Lakekeeper vends both automatically for
+exactly this reason, and calls out that there is then no per-vendor branch in client code.
+
+We emit this server-side, in the `storage_options` field the Lance spec already defines,
+which is strictly better than Lakekeeper's arrangement: no client library has to translate
+anything, so vending works from any stock Lance client rather than only from theirs.
+
+Guard the same way #10777 had to after review: bucket-scoped list grants need an `s3:prefix`
+condition, and a location containing `*` or `?` must be refused rather than widened into a
+resource pattern.
+
+## Auth and authorization
+
+Authentication reuses `S3Authenticator` and `CredentialValidator` as-is. The Lance spec maps
+identity to headers — `api_key` to `x-api-key`, `auth_token` to `Authorization: Bearer` — and
+SigV4 keeps working because it is the same authenticator the Iceberg catalog already fronts.
+
+Authorization needs nothing new. A Lance table gets the same ARN shape,
+`arn:aws:s3tables:...:bucket/B/table/NS/T`, so every existing table-bucket policy covers
+Lance tables with no new policy language and no second permission model. Route it through
+`s3tables/permissions.go` and inherit the `DefaultAllow` semantics the Iceberg server already
+mirrors from the S3 port.
+
+One spec quirk worth honoring: request context entries prefixed `header.` become request
+headers, and every response header comes back as a `header.`-prefixed context entry. Echoing
+`x-request-id` through it costs nothing and makes tracing work.
+
+## What to take from Lakekeeper
+
+Rejecting Lakekeeper's API shape does not mean rejecting what it learned building it.
+
+**Deregister is soft-delete, so implement it as one.** Lakekeeper gives generic tables
+soft-deletion with undrop and a `protected` flag that makes a drop require `force=true`.
+Lance already has the concept — `DeregisterTable` preserves the data and hides the table —
+so the `.lance-deregistered` marker is a soft-delete by another name, and a re-register is
+an undrop. A protection flag on table-bucket entries is worth having regardless of Lance:
+it is a few lines against the existing xattrs and it applies to Iceberg tables too.
+
+**Enforce one identifier space across entry kinds.** Lakekeeper rejects a generic table
+whose name collides with an Iceberg table or view in the same namespace. Our catalog entries
+already share one filer directory and already carry `s3tables.entryType`, so this is
+structurally true — but it has to be enforced deliberately on every path, or a Lance handler
+happily loads an Iceberg table's directory and vice versa. That is the same crossover bug
+class as the view/table rename authorization fixed in #10776; the `catalogEntryKind` pattern
+from that change is the thing to reuse rather than re-derive.
+
+**A re-vend path matters more than it looks.** Lakekeeper exposes `/credentials` separately
+from load, because STS credentials expire in the middle of long jobs and re-loading the
+whole table to refresh them is wasteful. In Lance the spec's answer is another
+`DescribeTable` with `vend_credentials: true`, which is fine — but it means `DescribeTable`
+must stay cheap when `load_detailed_metadata` is false, which is another reason not to open
+the dataset on that path.
+
+**Generic tables are a cheap orthogonal win.** Lakekeeper's real insight is that Delta,
+Parquet, CSV, Vortex and Paimon all get governance for free once the catalog stops caring
+what the format is. Our `Table.Format` field already exists and the only thing stopping it
+is the hard `"ICEBERG"` check in `handler_table.go:48`. Loosening that and letting the S3
+Tables API register a table with an arbitrary format and a location — no metadata, no
+commits — is a small change that makes every format cataloguable. It is independent of this
+design and probably worth doing first, since `Format: "LANCE"` is then just a value rather
+than a special case.
+
+**Skip remote signing.** It is Lakekeeper's fallback for S3-compatible stores with no STS,
+and their own documentation notes that Lance will not use it — format libraries with their
+own S3 client expect static credentials and do not implement the Iceberg signer protocol. We
+have STS, so vended credentials are the path, and the signer is not worth building for a
+client that cannot consume it.
+
+## Errors
+
+Lance uses `{code, error, detail, instance}` with numeric codes, not Iceberg's exception-type
+strings. The mapping is mechanical:
+
+| HTTP | code | when |
+| --- | --- | --- |
+| 400 | 13 InvalidInput | charset violations, malformed id, route/body mismatch |
+| 401 | 16 Unauthenticated | |
+| 403 | 15 PermissionDenied | |
+| 404 | 1 NamespaceNotFound, 4 TableNotFound, 11 TableVersionNotFound | |
+| 409 | 2/5 AlreadyExists, 3 NamespaceNotEmpty, 14 ConcurrentModification | |
+| 501 | 0 Unsupported | every phase-3 data operation |
+
+Route/body mismatch is a spec requirement, not a nicety: when the identifier appears in both
+the path and the body and they disagree, the server must return 400. Cheap to get right at
+the decode step, annoying to retrofit.
+
+## Route surface
+
+Phase 0 is not in this table: point a stock Lance client at the existing Iceberg catalog
+with the Iceberg impl, see how far it gets, and land the maintenance guard either way. That
+tells us what the native server actually has to beat.
+
+Phase 1, the whole `lance-spark` and `lance-ray` contract:
+
+```
+POST /v1/namespace/{id}/create         CreateNamespace       mode: Create|ExistOk|Overwrite
+GET  /v1/namespace/{id}/list           ListNamespaces
+POST /v1/namespace/{id}/describe       DescribeNamespace
+POST /v1/namespace/{id}/drop           DropNamespace         mode: Fail|Skip, behavior: Restrict|Cascade
+POST /v1/namespace/{id}/exists         NamespaceExists
+GET  /v1/namespace/{id}/table/list     ListTables            ?include_declared, ?page_token, ?limit
+GET  /v1/table                         ListAllTables
+POST /v1/table/{id}/declare            DeclareTable
+POST /v1/table/{id}/describe           DescribeTable         ?with_table_uri, ?load_detailed_metadata, ?check_declared
+POST /v1/table/{id}/exists             TableExists
+POST /v1/table/{id}/register           RegisterTable         mode: Create|Overwrite
+POST /v1/table/{id}/deregister         DeregisterTable
+POST /v1/table/{id}/drop               DropTable
+POST /v1/table/{id}/rename             RenameTable
+```
+
+`DescribeTable` with `load_detailed_metadata=false` needs only `location`, which is the
+common case and which we can answer from xattrs alone. With `load_detailed_metadata=true`
+the spec wants `version`, `schema` and `stats`, which means reading the Lance manifest. For
+phase 1, return the fields we can derive from the filer — `version` from the highest entry in
+`_versions/`, given V2 naming is `{u64::MAX - version:020}.manifest` and V1 is
+`{version}.manifest` — and omit `schema`/`stats` rather than fabricating them. The spec
+tolerates a partial response here; it does not tolerate a wrong one.
+
+Phase 2 was the five version operations plus `managed_versioning`; it was built and then
+removed, for the reasons under Commit safety.
+
+Phase 3 is the data plane: `CreateTable`, `InsertIntoTable`, `MergeInsertIntoTable`,
+`UpdateTable`, `DeleteFromTable`, `QueryTable`, `CountTableRows`, and the index and tag
+operations. These exchange Arrow IPC, and more to the point they require reading and writing
+the Lance file format, for which no Go implementation exists. Return `Unsupported` (code 0)
+and say so in the docs. `arrow-go/v18` is already an indirect dependency, so Arrow framing is
+not the blocker — Lance is.
+
+## Does a Lance table need maintenance?
+
+Yes, and one part of it has no Iceberg equivalent. The client exposes three jobs:
+
+- `optimize.compact_files()` — Lance writes a fragment per write batch, so a table fed by
+  small appends accumulates small files exactly the way an Iceberg table does.
+- `optimize.optimize_indices()` — **rows written after an index was built are not covered by
+  it.** A vector search against a stale index silently misses recent data. That is a
+  correctness-shaped failure, not a slow query, and it is specific to what people use Lance
+  for.
+- `cleanup_old_versions()` — every version is retained until something removes it. Lance can
+  do this itself: `optimize.enable_auto_cleanup()` sets it on the dataset, so this one need
+  not be an external job at all.
+
+None of it can run in the Go worker. All three read and rewrite Lance files, which needs
+Lance format code that does not exist in Go, and there is no useful subset either: deciding
+which fragments an old version still references means parsing Lance manifests.
+
+So the maintenance worker must not touch a Lance table, and it declines by reading the format
+the catalog recorded rather than by failing to parse Iceberg metadata.
+
+## The worker can be Rust, and it is not a sidecar
+
+The Go worker is not the only worker. `weed/pb/plugin.proto` defines `PluginControlService`,
+a language-agnostic gRPC stream that external maintenance workers connect on: the worker
+opens `WorkerStream`, sends `WorkerHello` with the job types it can `detect` and `execute`,
+answers `RequestConfigSchema` with a `JobTypeDescriptor`, replies to `RunDetectionRequest`
+with `JobProposal`s and to `ExecuteJobRequest` with `JobProgressUpdate`s and `JobCompleted`.
+`weed worker -admin=host:23646` is the Go reference implementation of exactly that contract,
+from outside the admin process.
+
+Nothing in it is Go-specific, and the Rust toolchain is already in the tree.
+`seaweed-volume/build.rs` compiles protos straight out of `../weed/pb/` with `tonic_build`,
+including `filer.proto`, on tonic 0.12 and prost 0.13. A Lance worker is that same build
+with `plugin.proto` added and the `lance` crate as a dependency — the real one, no FFI and
+no Python.
+
+Three job types, one per real maintenance operation:
+
+| Job type | Calls | Detected from |
+| --- | --- | --- |
+| `lance_compact` | `optimize.compact_files` | fragment count and sizes |
+| `lance_optimize_indices` | `optimize.optimize_indices` | rows an index does not cover |
+| `lance_cleanup_versions` | `cleanup_old_versions` | version count and age |
+
+What the existing machinery then supplies for free is the part worth noticing. Scheduling,
+retries, dedupe by `dedupe_key`, progress reporting, per-job concurrency limits and the
+admin settings page all come from the protocol: a worker that answers `RequestConfigSchema`
+with a descriptor gets its configuration form rendered in the admin UI without a line of Go
+or templ. A Rust worker is a first-class maintenance worker, not an appendage.
+
+The remaining wiring is small and mostly decided already. `RunDetectionRequest` carries a
+`ClusterContext` with filer and S3 addresses plus a free-form `metadata` map, which is where
+the Lance namespace URL goes; the worker lists Lance tables from the namespace, which is the
+catalog of record and already filters by format. It gets at the data by asking
+`DescribeTable` for `storage_options` with `vend_credentials`, so the worker is just another
+client of the STS path rather than a component with its own credentials. And when it commits
+a compaction it goes through `CreateTableVersion` like any other writer, which is what
+managed versioning was for.
+
+## The worker is also the only thing that can describe the table
+
+Admin can render an Iceberg table because it can read Iceberg metadata. It cannot read
+Lance: it knows the dataset's location and its format string, and that is the whole of it.
+The details page showed a location and two empty panels, which is an honest answer and a
+useless one.
+
+The worker already knows. Detection opens every dataset to decide whether it needs
+compacting, so at that moment it holds the schema, the row count, the fragment count and
+the version count. It just had no way to say so — every message on the stream was about
+work.
+
+So `WorkerObservations` is a body on `WorkerToAdminMessage`: a repeated `ObjectObservation`
+of `object_id`, `object_kind`, `format`, and a `ConfigValue` map the worker fills with
+whatever it can cheaply say. Admin keeps the last observation per object and serves it back
+with the time it was taken and the worker that took it. Nothing schedules from it, and it is
+not authoritative — it is a cache with its staleness on the label, which is why the page
+badges it rather than presenting it as metadata it read itself.
+
+The keys are the worker's to choose, which keeps the protocol out of the business of knowing
+what a Lance table is. A worker for any other format admin cannot parse describes itself the
+same way.
+
+## A bucket declares its format
+
+Format was recorded per table, which is enough for the storage layer and not enough for
+anything that has to answer a question about a bucket. The admin UI printed one Iceberg
+endpoint for every bucket, including the ones holding Lance datasets, where that endpoint
+serves nothing; an empty bucket had no format at all.
+
+So `CreateTableBucket` takes an optional `format`, stored with the rest of the bucket
+metadata. Empty means `ICEBERG` - what AWS S3 Tables serves, and therefore what an SDK
+that has never heard of the field means. `CreateTable` refuses another format, and
+`CreateView` refuses outright outside an Iceberg bucket, a view being Iceberg metadata.
+The Lance namespace declares `LANCE` for the buckets it creates.
+
+**Enforced rather than defaulted**, because the point of showing a format at all is the
+endpoint that follows from it, and that endpoint is only truthful if the bucket holds one
+format. **Buckets that already exist stay undeclared** and keep taking anything: nothing is
+migrated, and the UI shows "unset" as a fact about the bucket's age rather than a fault.
+That state is also the only way to hold both formats at once, which is what the
+Iceberg-REST adapter path produces.
+
+## Sample rows are fetched, not cached
+
+The same asymmetry has a second half. Admin renders an Iceberg table's rows by
+reading its Parquet files directly; for Lance it has nothing to read with, so the data
+page offered a Browse Data button that led to an empty grid.
+
+`RequestObjectPreview` / `ObjectPreviewResponse` mirror the config-schema round trip
+already on the stream: admin asks, the worker scans the dataset and hands back rows it
+has already rendered as text, because it is the only side that knows the types. Admin
+picks the worker from the observation store, so the one that last described a table is
+the one asked to read it.
+
+The rows are deliberately not cached, and that is the line between the two channels. An
+observation describes an object, so a copy with a timestamp on it is useful. Rows are the
+object's contents: a copy held in admin would be stale, larger, and nobody's business.
+The page fetches on load, bounded, or says why it cannot.
+
+## The sidecar question
+
+The data plane is a different problem, and this design previously conflated the two.
+Maintenance rides the worker protocol; `QueryTable` and `InsertIntoTable` do not, because
+they are synchronous REST operations on the namespace's own surface. Serving those means a
+Rust process that answers HTTP, either behind the Go namespace as a proxy target or in front
+of it. It would make SeaweedFS a store you can run vector search *in* rather than one you
+read vectors *out of*, which is the larger prize and the reason to keep the option open.
+
+Neither should gate phase 1. Phases 1 and 2 are pure Go over the filer and are worth
+shipping on their own — they are what makes Spark and Ray work.
+
+## Testing
+
+Mirror the Iceberg package: `httptest` plus a fake filer client for the handler tests, in
+`weed/s3api/lance`. Then an integration suite under `test/s3tables/catalog/` next to the
+existing `pyiceberg_test.go`, driving the generated Python `lance-namespace` client against
+a live gateway. Three things that suite must cover and unit tests cannot:
+
+- the storage-options key names actually work, i.e. a client that gets `storage_options` from
+  `DescribeTable` can open the dataset;
+- a table created through the catalog is visible to `lance.dataset()` by URI and to a V1
+  directory-catalog client rooted at the namespace prefix;
+- concurrent writers do not lose a commit, which is the phase-2 acceptance test and the
+  thing that justifies the external manifest store.
+
+Phase 1 is validated: `lance_namespace` 0.11.1 with `impl=rest` drives the namespace,
+`lance.write_dataset` writes to the vended location with the vended `storage_options`, and
+the rows read back. Note that this client version drops `check_declared` and
+`include_declared` on the wire, so `is_only_declared` reads null through it however the
+server behaves.
+
+The commit path is validated at both levels. The mechanism: eight writers race the same
+manifest key through S3 with `If-None-Match: *`, and exactly one wins. The property that
+actually matters, which single-winner exclusivity does not by itself establish: eight
+writers append to one dataset concurrently through lance, and afterwards every batch is
+still there — the losers saw the conflict, rebased, and committed again. That second test
+is also the sequence managed versioning could not complete at all, since its store answers
+"put_if_not_exists is not supported" to the second commit.
+
+One more that belongs in the Iceberg suite, not this one: a Lance dataset registered through
+the Iceberg adapter must survive a full maintenance pass. Reading the code, that test should
+fail today; it has not been run.
+
+## Open questions
+
+- Root-level `ListNamespaces` enumerating table buckets is convenient and is a listing
+  surface we do not have on the Iceberg side. Decide whether it is gated behind a flag.
+- Whether the `.lance` directory suffix is worth the divergence from the Iceberg layout. I
+  think yes — it is what makes the catalog optional — but it means the two catalogs' tables
+  do not look alike on disk, and the admin UI has to know that.
+- Names: our charsets are lowercase-only and Lance identifiers are arbitrary strings. Reject
+  and document, as Iceberg does, or case-fold. Rejecting is right, but see #10734 for how
+  case handling bites when only one side normalizes.
+- Whether to land generic-format registration first. Dropping the `"ICEBERG"` check and
+  letting a table carry an arbitrary format plus a location is smaller than this whole
+  design, gets Delta and Parquet catalogued as a side effect, and turns `Format: "LANCE"`
+  into an ordinary value. The argument against is that it invites tables the maintenance
+  worker cannot service, so it needs a "catalog-only, no maintenance" marker to be honest.

+## Verify an image signature
+
+Every image CI pushes to `chrislusf/seaweedfs` and `ghcr.io/chrislusf/seaweedfs` is signed with [cosign](https://docs.sigstore.dev/cosign/verifying/verify/), keyless, by the GitHub Actions workflow that built it, so there is no key to fetch or pin. The signature is attached to the image digest and covers the multi-arch index and each platform image in it; `latest` is the release image under another tag and verifies the same way. Images published before September 2026 predate signing.
+
+```bash
+cosign verify \
+  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
+  --certificate-identity-regexp '^https://github.com/seaweedfs/seaweedfs/\.github/workflows/container_release_unified\.yml@' \
+  chrislusf/seaweedfs:latest
+```
+
+cosign prints the digest it verified. Deploy by that digest, or let an admission controller resolve the tag, so what runs is what was checked.
+
+The identity is `https://github.com/seaweedfs/seaweedfs/.github/workflows/<workflow>@<ref>`. The ref is `refs/tags/<version>` for a release and `refs/heads/master` when a variant was republished by hand. The workflow is `container_release_unified.yml` for the release images, `container_dev.yml` for `dev`, `container_latest.yml` for a `latest` rebuilt by hand, `container_release_foundationdb.yml` for the `_large_disk_foundationdb` release image, and `container_foundationdb_version.yml` or `container_rocksdb_version.yml` for the per-version builds. The regexp above accepts release images only; `container_[a-z_]+\.yml@` accepts everything this repository publishes, `dev` included.
+
+The same check as a Kyverno policy, release images only:
+
+```yaml

+  name: verify-seaweedfs-images

+
+`accessKeyKey` and `secretKeyKey` default to the chart's own key names
+(`admin_access_key_id`, `admin_secret_access_key`, and the `read_` pair). The
+generated `seaweedfs_s3_config` references the keys as `${SEAWEEDFS_S3_ADMIN_ACCESS_KEY_ID}`
+and the gateway resolves them from the environment, which the chart wires up
+from the Secret. Nothing is read from the cluster at render time, so
+`helm template`, `--dry-run` and an Argo CD diff all render what an install
+applies. Rotating a key in the Secret takes effect on the next pod restart, as
+with any other environment variable. The COSI driver parses the config itself
+and does not resolve these references.

 ## Admin Component
 
 The admin component provides a modern web-based administration interface for managing SeaweedFS clusters. It includes:

 As an alternative, a kubernetes Secret can be used (`admin.secret.existingSecret`).
 
+### Admin listen address
+
+Since SeaweedFS 4.46, `weed admin` defaults to listening on loopback (`127.0.0.1`).
+The chart's httpGet readiness/liveness probes dial the pod IP, so the admin
+server must bind a non-loopback address for the probes to succeed. The chart
+therefore passes `-ip={{ .Values.admin.ip }}`, defaulting `admin.ip` to `0.0.0.0`
+(the pre-4.46 behaviour of listening on all interfaces).
+
+Binding a non-loopback address requires authentication: `weed admin` refuses to
+start on a non-loopback address without `-adminPassword`, so the chart fails at
+render time if `admin.ip` is non-loopback and authentication is not configured via
+`admin.secret.adminPassword`, `admin.secret.existingSecret`, or
+`WEED_ADMIN_PASSWORD` supplied through `admin.extraEnvironmentVars` /
+`admin.secretExtraEnvironmentVars`. Setting `admin.allowInsecureBind` renders
+`-allowInsecureBind` and bypasses this guard; it leaves the admin API
+unauthenticated on the network, so use it only when access is otherwise
+restricted (e.g. network policies). The whole `127.0.0.0/8` range and `::1` are
+treated as loopback (matching `weed admin`); `localhost` is treated as
+non-loopback. Set `admin.ip` to a loopback address only if you also replace the
+httpGet probes (e.g. with an `exec` probe that checks `127.0.0.1`).
+
+The `-ip` flag requires SeaweedFS 4.46 or newer; pinning `admin.imageOverride`
+to an older image is not supported with this chart version.
+
 ### Admin Data Persistence
 
 The admin component can store configuration and maintenance data. You can configure storage in several ways:
@@ -520,6 +570,14 @@ Two things worth knowing before you turn this on:
 
 The DNS selectors default to CoreDNS as kubeadm, kind and the managed offerings from AWS, Google and Azure install it. On OpenShift, override `egress.dnsNamespaceSelector` and `egress.dnsPodSelector` to match `openshift-dns`; see the comment in `values.yaml`.
 
+## Pod and container security contexts
+
+Pod and container security contexts are configurable independently for every built-in workload and remain empty by default for backwards compatibility. The examples in `values.yaml` show how to enable a `RuntimeDefault` seccomp profile, disable privilege escalation and privileged mode, and drop all Linux capabilities.
+
+The chart does not enable `runAsNonRoot` by default because its default `hostPath` storage may be owned by root. To enforce the Kubernetes `restricted` Pod Security Standard, use storage that is writable by a non-root user and configure `runAsNonRoot` or use the OpenShift overrides below.
+
+Security contexts configured for a component also apply to the chart-managed helper containers for that component. User-provided init containers and sidecars must define their own container security context.
+
 ## OpenShift Support
 
 SeaweedFS can be deployed on OpenShift or any cluster enforcing the Kubernetes "restricted" Pod Security Standard. By default, OpenShift blocks containers that run as root or use `hostPath` volumes.
