From 6a63657298b8b3f0a71776bf8304489e73a5ca5c Mon Sep 17 00:00:00 2001 From: Amantux Date: Fri, 11 Sep 2026 04:32:55 +0000 Subject: [PATCH 001/110] docs: standardize operator-facing tape devices on the no-rewind /dev/nstN nodes docs/hardware-setup.md said /dev/st0 while tests/hardware/README.md already used /dev/nst0. LTFS on a rewinding node repositions the tape on every close and can corrupt the index, so every instruction, example and --device flag now names the no-rewind node, with a short section in docs/hardware-setup.md explaining why. Parser fixtures and sample tool output (openblade/hardware/{discovery,ltfs,mtx}.py, tests/unit/*, the nst->st normalizers in tests/hardware/) are left alone: lsscsi and ltfs genuinely report /dev/stN and falsifying that output would break the parsers and mislead operators reading real tool output.

This adds a never-auto-loaded example override that maps the changer sg node and up to three drives (/dev/nst0..2 plus their sg nodes, one commented block per drive so operators delete what they lack) and wires OPENBLADE_BACKEND / OPENBLADE_REAL_HARDWARE_ENABLED / OPENBLADE_CHANGER_DEVICE / OPENBLADE_DRIVE_DEVICES. Two findings, both verified empirically rather than assumed: * No cap_add and no privileged: true are needed. A container holding only --device /dev/sgN and the default capability set (CapEff 0xa80425fb, no CAP_SYS_RAWIO) accepted SG_IO for every opcode these backends use - INQUIRY, MODE SENSE, READ ELEMENT STATUS, MOVE MEDIUM, INITIALIZE ELEMENT STATUS, READ/WRITE(6), WRITE FILEMARKS, SPACE, LOAD/UNLOAD. Adding CAP_SYS_RAWIO changed nothing. * The real blocker is ownership, not capabilities: devices: reproduces the node with the host's uid/gid/mode and the image drops to the unprivileged openblade user via gosu, so uid 1000 got EACCES on open() until the node's gid was added as a supplementary group. Hence group_add with a required OPENBLADE_TAPE_GID, which fails loudly at compose time rather than as a confusing permission error on the first SCSI call. Also noted in-file: the image ships mtx but not sg3_utils or LTFS, so only read-only changer inventory works in-container as shipped. Bare-metal venv remains the recommended bring-up path per the runbook; both docs/hardware-setup.md and docs/deployment.md say so where they point here.

The library is configured with product id "QUANTUM Scalar" so mhvtl selects its Scalar personality module, whose SCSI element addressing (drives at 0x0100, storage at 0x1000) is the realistic Scalar i3 case rather than the 0-/1-based default. That is the element-addressing trap the bring-up plan asks this phase to rehearse. Three upstream obstacles had to be solved to get here; all are documented inline where they bite: - mhvtl's scalar_pm.c aborts vtllibrary with heap corruption. Two snprintf bounds exceed their alloc_vpd() page (VPD 0x80 and 0x83), and both functions free the old page without storing the new one back into lu->lu_vpd[], leaving a dangling pointer. Fixed in patches/0001-scalar_pm-fix-vpd-overflow-and-uaf.patch. - mhvtl's own systemd units stop its daemons from working. ProtectClock=yes implies a DeviceAllow= rule, which flips the cgroup device policy to "closed" and denies the daemon its own /dev/mhvtl node; ProtectKernelTunables=yes makes /sys read-only so the daemon cannot write add_lu to register its LU, leaving a daemon that reports "active" while no SCSI device ever appears. Worked around with /run drop-ins. - lsscsi prints the mediumx row before udev creates its /dev/sg node, so a naive readiness check sees a changer with no usable device path. setup.sh also prints the SCSI-address -> /dev/st -> serial correlation on every run: /dev/stN numbering follows daemon registration order, and we observed target 1/2/3 mapping to st2/st1/st0 on one boot and st0/st1/st2 on the next. That is the "wrote to the wrong drive" trap, so it is reported rather than assumed.

Verified against the installed sg3-utils 1.46 (`sg_inq` 2.10 20210328): plain `sg_inq DEVICE` fetches the Unit Serial Number VPD page (0x80) by DEFAULT, so no flag change is needed — `-o/--only` is what suppresses it. That same version prints "Peripheral device type:" rather than "Device type:", which the existing regex did not match, so the device-type pattern now accepts both spellings.

With >=2 drives that is the "wrote to the wrong drive" bug from the i3 bring-up runbook. New openblade/hardware/correlation.py binds each drive element to a host device: - OPENBLADE_DRIVE_SERIAL_MAP=":,..." declares the mapping; every configured device is probed with sg_inq at backend construction and compared against it. A declared serial that is not attached, an attached drive that is not declared, a duplicate serial, a drive with no serial, or an element index beyond the changer's drive count raises DriveCorrelationError (a SafetyViolationError) and the backend refuses to start. - With no map, correlation falls back to positional order and logs a DRIVE ORDER UNVERIFIED warning listing the observed serials, so the operator can build the map from the log. Single-drive behaviour is unchanged. - Dry runs probe nothing and are reported as unverified rather than claimed. OPENBLADE_DRIVE_DEVICES is now authoritative over discovery order, and connect-i3 reports the correlation plus how it was established. The READ ELEMENT STATUS/DVCID route was rejected deliberately: it needs a new binary dependency and a hex descriptor parser that cannot be validated against any captured real-i3 output. Rationale is in the module docstring. --- openblade/config.py | 55 +++ openblade/domain/errors.py | 9 + openblade/hardware/correlation.py | 256 ++++++++++++++ openblade/hardware/library.py | 45 ++- openblade/hardware/validation.py | 9 + tests/unit/test_drive_correlation.py | 312 ++++++++++++++++++ tests/unit/test_real_library_drive_mapping.py | 152 +++++++++ 7 files changed, 828 insertions(+), 10 deletions(-) create mode 100644 openblade/hardware/correlation.py create mode 100644 tests/unit/test_drive_correlation.py create mode 100644 tests/unit/test_real_library_drive_mapping.py diff --git a/openblade/config.py b/openblade/config.py index 37bd9ef..d9b7fab 100644 --- a/openblade/config.py +++ b/openblade/config.py @@ -43,7 +43,16 @@ class OpenBladeConfig: drive_timeout_seconds: int = 300 hardware_dry_run: bool = False changer_device: str | None = None + # Host tape devices, in LIBRARY drive-element order when no serial map is + # declared.

for the simulator, scheduler and hardware suite - tests/integration/test_three_drive_concurrency.py: three jobs on three drives with disjoint scheduler + JobQueue ownership, the shipped scalar-i3-50-3 profile asserted at three drives, and MockLibraryBackend asserted configurable at 1/2/3/6 drives. - tests/hardware/test_sharded_operations.py: the timeout test sized the pool at min(drives, 2), making it a 2-drive test on a 3-drive library; it now sizes to the attached drives. - tests/hardware/test_device_discovery.py: sg_inq is exercised for drives 0-2 (skipping absent ones) instead of drive 0 only, plus a check that attached drives report distinct serials, which OPENBLADE_DRIVE_SERIAL_MAP depends on. --- tests/hardware/test_device_discovery.py | 20 ++-

Both parsers were written against hand-made sample strings that do not match what mtx actually prints. 1. mtx is inconsistent about whitespace around '=': Data Transfer Element 0:Full (Storage Element 6 Loaded):VolumeTag = OB0007L8 Storage Element 1:Full :VolumeTag=OB0001L8 _BARCODE_RE required the tight form, so every tape loaded in a DRIVE parsed as barcode=None. find_drive_by_barcode() was permanently blind and archive jobs failed with "Barcode ... not found in inventory" about a tape sitting in drive 0. SAMPLE_MTX_LOADED uses the tight form on its drive line, which is why no unit test caught it. This would have fired on the i3 the first time a tape was loaded. 2. _SLOT_RE matched "Storage Element (\d+):" and so did not match "Storage Element 9 IMPORT/EXPORT:Empty". All four I/E slots vanished from the inventory, leaving len(slots)=8 while the header reported 12 slots, and making a tape parked in the mailslot invisible to find_slot_by_barcode(). Phase 3.4 of the bring-up plan predicted i3 I/E slots would be where these regexes diverge; they were right. MtxSlotInfo gains is_import_export so callers can tell the two apart, and the parsed slot count now agrees with the header. Regression tests are anchored on SAMPLE_MTX_REAL_SCALAR - output captured byte-for-byte from the rig, including the trailing barcode padding - rather than on another hand-written sample, since hand-written samples are exactly how these bugs hid. Mutation-checked: restoring the tight VolumeTag regex fails 1 of 7, restoring the I/E-blind slot regex fails 3 of 7.

None were visible without a real LTFS binary; the module's sample strings are fictional. 1. device_list() could never succeed. `ltfs -o device_list` writes its entire output to STDERR and exits 1 even on success, so raise_on_error() raised unconditionally and parsing result.stdout would have found nothing anyway. The real output format is also nothing like the sample the regex was built from: Device Name = /dev/sg1 (14.0.1.0), Vendor ID = IBM , \ Product ID = ULT3580-TD8 , Serial Number = OBLADE_D01, ... Now parses stdout+stderr, judges success by whether any device parsed, and accepts both formats. LTFSDevice gains `serial`, because correlating drives by serial is the documented mitigation for the wrong-drive trap - device ordering is not trustworthy. 2. LTFS was handed the wrong device node. Its sg backend addresses drives as /dev/sgN; library.py supplies /dev/stN. This does not fail cleanly - LTFS reads the wrong device and reports "No index found in the medium", which looks like blank or corrupt media. On the i3 that is a support incident where the operator concludes the cartridge is bad. Added discovery.resolve_sg_device(), which reads the mapping from /sys/class/scsi_{tape,changer}//device/scsi_generic/ and is applied in format_tape/mount_readonly/mount_readwrite. The mapping must be READ, not derived: st and sg numbers are allocated independently, and this rig routinely produces st0 -> sg1 and st2 -> sg4. 3. unmount() returned while the drive was still held. umount returns when the kernel detaches the filesystem, but the LTFS FUSE process lives on to flush its index and close the drive; until it exits the next mount of that drive fails with "Cannot open device: failed to open /dev/sgN (16)" (EBUSY). Any unmount/remount cycle hits this, and so does unload-then-reload on a real library. Added wait_for_ltfs_release() (procfs poll, bounded) and report device_released in the result details. Mutation-checked: a naive st->sg name derivation fails 5 of 7 resolve tests; removing the real-format branch fails 4 of 5 LTFS parser tests. Note for whoever owns library.py: _ordered_drive_devices() prefers block_device, i.e. the REWINDING /dev/stN node, which is the source of (2) and is the corruption footgun Phase 0.3 of the bring-up plan calls out. ltfs.py now defends itself, but that should prefer sg_device. Detail in docs/runbooks/mhvtl-rehearsal.md section 4.

Drives are empty most of the time on a real library, so this was a guaranteed false failure, not an occasional one. Now prefers the sg node, falling back to discovery.resolve_sg_device(). 2. _format_tape() passed the barcode as mkltfs --tape-serial, which takes exactly 6 alphanumeric characters. Real LTO barcodes are 8 (six plus a media-type suffix such as "L8"), so it failed every time with "LTFS15029E Tape serial must be 6 characters." The barcode belongs in --volume-name, which is what the product code in ltfs.py already used correctly. The helper also passed /dev/nstN where LTFS needs the sg node. The second bug existed in TWO hand-rolled copies, in test_ltfs_operations.py and test_performance.py, both diverging from the product's correct version. Both fixed; collapsing them onto LTFSCommandBackend is left as follow-up. _unmount_ltfs in both files now waits for wait_for_ltfs_release() as the product does, so a remount cannot race the still-closing LTFS process.

Phase 4 of the bring-up plan sequences format before archive/restore, so the rig now supplies formatted scratch media as a precondition. setup.sh runs it when mkltfs is present and says plainly what is untested when it is not. - reset.sh: returns every loaded tape to its home slot. A test that fails part way through leaves media in a drive, and the next run then skips itself with "Drive 0 is not empty" or "Scratch barcode ... is not currently present" - cascading skips that look like passes. - mhvtl.conf: CAPACITY 500 -> 8000 MB. The suite writes 100 MB payloads and several in a row; 500 MB cartridges fail mid-test with ENOSPC from inside the LTFS mount, which reads as an OpenBlade bug and is not. Backing files are sparse, so this costs only what is actually written. - setup.sh waits for the /dev/sg nodes rather than the lsscsi rows, and prints the SCSI-address -> /dev/st -> serial correlation on every run. - README.md: the configuration, the three upstream mhvtl bugs the rig works around, and the two traps it exists to expose (drive order is not device order; sg/st/nst are not interchangeable).

The raw addresses matter to anything issuing SCSI directly.) + +## Three upstream obstacles this rig works around + +All three are mhvtl bugs, not OpenBlade bugs. Each is documented at the point it +bites; summarised here so you recognise the symptom on a new host. + +**1. `vtllibrary` aborts with heap corruption under the Scalar personality.** +`malloc(): invalid next size (unsorted)`, immediately after +`smc_personality_module_register(): mhVTL - Scalar emulation`. `scalar_pm.c` has +two `snprintf` bounds that exceed their `alloc_vpd()` page (VPD `0x80` writes 25 +bytes into 24; VPD `0x83` writes 25 bytes at offset 12 of a 36-byte page), and +both functions free the old page **without storing the new one back into +`lu->lu_vpd[]`**, leaving a dangling pointer. Fixed by +`patches/0001-scalar_pm-fix-vpd-overflow-and-uaf.patch`, which `setup.sh` +applies. + +**2. mhvtl's own systemd units stop its daemons from working.** Two independent +problems in `vtltape@.service` / `vtllibrary@.service`: + +- `ProtectClock=yes` implies a `DeviceAllow=` rule, and setting *any* + `DeviceAllow` switches the cgroup device policy from `auto` to **closed** — + which then denies the daemon its own `/dev/mhvtl` node. Symptom: + `chrdev_create(): Error creating device node for mhvtl: Operation not + permitted`, or `Could not open transport for minor NN: Operation not + permitted`. +- `ProtectKernelTunables=yes` mounts `/sys` read-only, so the daemon cannot + write `/sys/bus/mhvtl/drivers/mhvtl/add_lu` to register its logical unit. + Symptom — the nasty one — the daemon reports **`active`** while **no SCSI + device ever appears**: `Could not open 'add_lu': Read-only file system`. + +`setup.sh` writes drop-ins under `/run/systemd/system/` (so they vanish on +reboot and never edit a packaged unit) re-allowing the module's dynamic +character major and turning `ProtectKernelTunables` off. + +**3. `lsscsi` prints the `mediumx` row before udev creates its `/dev/sg` node.** +A readiness check that waits only for the row sees a changer whose sg column is +`-`, and `mtx -f -` then fails. `setup.sh` waits for the sg nodes themselves. + +## Two traps this rig is specifically here to expose + +**Drive order is not device order.** mhvtl hands out `/dev/stN` in daemon +*registration* order, which does not track SCSI target order. Across reboots of +this rig we have seen targets 1/2/3 map to `st0/st1/st2` **and** to `st2/st1/st0`. +`setup.sh` prints the SCSI-address → `/dev/st` → serial correlation on every run +rather than letting anyone assume it. Correlate drives by **serial number**, never +by device numbering — the same instruction Phase 3 gives for the real i3. + +**`/dev/sg`, `/dev/st` and `/dev/nst` are not interchangeable.** + +- LTFS's `sg` backend addresses drives as `/dev/sgN`. Given `/dev/st0` it reads + the wrong device and reports `No index found in the medium` — a wrong-device + error that looks exactly like blank media. +- `sg_inq` against the **rewinding** `/dev/stN` exits 50 (`close error: No medium + found`) whenever the drive is empty, because closing a rewinding node attempts + a rewind. The inquiry succeeds; the command still reports failure. +- `stN` and `sgN` numbers are allocated independently. `st0 -> sg1` and + `st2 -> sg4` are both real pairings from this rig. Never derive one from the + other; `openblade.hardware.discovery.resolve_sg_device()` reads the mapping + from sysfs. + +## Requirements + +- Linux with headers for the **running** kernel (`linux-headers-$(uname -r)`). +- Secure Boot **disabled**, or the unsigned out-of-tree module will not load. +- Root.

Phase 2 of real-i3-bringup-plan.md executed end to end: mhvtl and LTFS both built from source (neither is packaged on Ubuntu), one changer + three LTO-8 drives + 8 barcoded slots, and the full tests/hardware/ suite driven against the real hardware backend for the first time. Result: 24 pass / 8 fail / 24 skip on the first run, 48 pass / 0 fail / 8 skip at the end. Six product defects found and fixed, each with the failure output that exposed it and a note on how it would have presented at the i3. Two suspected bugs in library.py are reported rather than changed, since that file is owned elsewhere. Section 6 is deliberate: TapeAlert/diagnostics, robotics timing and failure modes, raw element addressing, media compatibility and control-path bridging are all still unrehearsed. Phases 3 and 4 stand unchanged. What this removes is the class of failure where the parsers and device plumbing are wrong - and it found six of those.

The repo's `SAMPLE_MTX_LOADED` uses the tight form on its +drive line, which is why unit tests never caught it. + +This would have fired on the i3 the first time a tape was loaded. Fixed; regex +now tolerates optional whitespace. + +### 3.2 `mtx.py` — import/export slots silently dropped + +`_SLOT_RE` matched `Storage Element (\d+):`, which does not match +`Storage Element 9 IMPORT/EXPORT:Empty`. All four I/E slots vanished from the +inventory, leaving `len(status.slots) == 8` while the header said 12. A tape in +the mailslot was invisible. + +The bring-up plan flags i3 I/E slots as a likely regex divergence (Phase 3.4). +It was right. Fixed; `MtxSlotInfo` gained an `is_import_export` flag and slot +count now agrees with the header. + +### 3.3 `ltfs.py` — `device_list()` could never succeed + +Three independent problems, all invisible without real LTFS: + +- `ltfs -o device_list` writes its **entire output to stderr**; the code parsed + `result.stdout`, which is empty. +- It **exits 1 even on success**; the code called `raise_on_error()`, so the + method raised unconditionally. +- The real output format is + `Device Name = /dev/sg1 (14.0.1.0), Vendor ID = IBM, ... Serial Number = OBLADE_D01`, + nothing like the fictional `LTFS14001I 0: /dev/st0 (...)` sample the regex was + written against. + +Fixed: parses stdout+stderr, judges success by whether devices were parsed, and +handles both formats. `LTFSDevice` gained a `serial` field — see §4. + +### 3.4 `ltfs.py` / `discovery.py` — LTFS was given the wrong device node + +The LTFS `sg` backend addresses drives as `/dev/sgN`. `library.py` supplies +`/dev/stN`. Handing LTFS `/dev/st0` does **not** produce a clean error — it +reads the wrong device and reports: + +``` +LTFS17016E Cannot parse index direct from medium (-21700). +LTFS11253E No index found in the medium. +LTFS11027E Cannot mount volume: medium consistency check failed. +``` + +which reads as *blank or corrupt media*. On the i3 that is a support incident +where the operator concludes the cartridge is bad. + +Added `discovery.resolve_sg_device()` — reads the mapping from +`/sys/class/scsi_{tape,changer}//device/scsi_generic/` — and applied it in +`format_tape`, `mount_readonly`, `mount_readwrite`. **The mapping must be read, +not derived:** `st` and `sg` numbers are allocated independently, and this rig +routinely produces `st0 -> sg1` and `st2 -> sg4`. + +### 3.5 `ltfs.py` — unmount returned before the drive was released + +`umount` returns when the kernel detaches the filesystem, but the LTFS FUSE +process lives on briefly to flush its index and close the drive. Until it exits +the drive's sg node is held, and the next mount fails: + +``` +LTFS30210I Cannot open device: failed to open /dev/sg2 (16). # EBUSY +``` + +Any unmount→remount cycle hits this, and on a real library so does +unload→reload. Added `wait_for_ltfs_release()` (polls procfs, bounded 60 s); +`unmount()` now waits and reports `device_released` in its result details. + +### 3.6 Test-side defects — `sg_inq` on a rewinding node, and `--tape-serial` + +Two bugs in `tests/hardware/` helpers, both of which would have produced false +failures against the i3: + +- `_resolve_scsi_path()` normalised `/dev/nst0` → `/dev/st0` for matching and + then **returned the rewinding node**. `sg_inq /dev/st0` exits 50 + (`close error: No medium found`) whenever the drive is empty, because closing + a rewinding node attempts a rewind. The inquiry itself succeeds — the command + still reports failure. Drives are empty most of the time, so this was a + guaranteed false failure. Now prefers the sg node. +- `_format_tape()` (duplicated in `test_ltfs_operations.py` **and** + `test_performance.py`) passed the barcode as `--tape-serial`, which takes + **exactly 6 alphanumeric characters**. Real LTO barcodes are 8 (six plus a + media-type suffix like `L8`), so this failed every time with + `LTFS15029E Tape serial must be 6 characters.` The barcode belongs in + `--volume-name`, which is what the product code already used correctly. Both + copies fixed. + + *The duplication is the underlying smell:* two hand-rolled copies of the LTFS + invocation in two test files, both diverging from the product's own correct + version. Worth collapsing onto `LTFSCommandBackend` later. + +### Regression tests + +Every fix ships with one, in `tests/unit/test_hardware_parsers.py`: +`TestMtxParserAgainstRealOutput` (7), `TestLTFSParserAgainstRealOutput` (5), +`TestResolveSgDevice` (7). They are anchored on byte-accurate captured output — +`SAMPLE_MTX_REAL_SCALAR` and `SAMPLE_LTFS_DEVICE_LIST_REAL` — rather than on +hand-written samples, which is precisely how the original bugs hid. + +**All were mutation-checked.** Each fix was reverted and the corresponding tests +confirmed to fail, then restored: + +| Mutation | Tests that failed | +|---|---| +| tight `VolumeTag=` regex restored | 1 of 7 | +| I/E-blind slot regex restored | 3 of 7 | +| `resolve_sg_device` → naive name derivation | 5 of 7 | +| real-format branch removed from LTFS parser | 4 of 5 | + +--- + +## 4. Suspected bugs in `library.py` — NOT fixed here + +`openblade/hardware/library.py` is owned by a parallel agent, so these are +reported rather than changed. Both concern `_ordered_drive_devices()`. + +**(a) It returns the REWINDING `/dev/stN` node.** It prefers `block_device` over +`sg_device`, and `lsscsi` reports `/dev/st0` in the block column. Every consumer +of `drive_device()` therefore gets a rewinding node. This is the direct cause of +§3.4, and Phase 0.3 of the bring-up plan explicitly calls LTFS-on-a-rewinding- +device a corruption footgun. `ltfs.py` now defends itself with +`resolve_sg_device()`, but the source should prefer `sg_device`, or at minimum +the no-rewind `nst` node. + +**(b) Drive ordering is assumed, and the assumption is fragile.** It sorts by +`(host, bus, target, lun)` and indexes by `drive_id`. On this rig that ordering +is **correct** — verified by serial: changer Data Transfer Element 0 is +`OBLADE_D01` at `[14:0:1:0]`, which is the first row in SCSI-address order. + +But it is correct by luck of mhvtl's config ordering, and the *device names* +around it are not stable at all. Across reboots of this same rig: + +| boot | target 1 | target 2 | target 3 | +|---|---|---|---| +| A | `/dev/st0` | `/dev/st1` | `/dev/st2` | +| B | `/dev/st2` | `/dev/st1` | `/dev/st0` | +| C | `/dev/st1` | `/dev/st2` | `/dev/st0` | + +So sorting by SCSI address is defensible and sorting by device name would be +actively wrong — but neither is *verified*. Phase 2 of the plan asks for exactly +this to be proven with ≥2 drives, and the honest answer is: **the ordering +happens to hold on mhvtl, and nothing checks it.** Recommend correlating changer +elements to drives by **serial number** (`sg_inq`, or the new `LTFSDevice.serial`) +and failing loudly on mismatch, before the first multi-drive write to the i3. +`scripts/mhvtl/setup.sh` now prints the correlation table on every run. + +*No bugs suspected in `sg.py` — `parse_sg_inq` handled real `sg_inq` output +unchanged.* + +--- + +## 5.

The barcode-reader lag noted in the LTO-7 quirks section, load timeouts, + and retry paths cannot appear here. +- **Real element addressing.** The rig uses the Scalar personality's element + addresses deliberately, but `mtx` normalises them to 1-based logical numbers + before OpenBlade ever sees them. Phase 3.4's "diff real `mtx status` against + the samples" is still required at the i3. +- **Media compatibility, LTO generation rules, cleaning cycles, WORM.** +- **Control-path/LUN-1 bridging** — the "no `mediumx` appears" failure mode from + Phase 1 is structurally absent here. +- **Dirty-unmount recovery**, which needs process control beyond `SafeRunner`. + +Phases 3 and 4 stand unchanged.

This also matches the repo's other sg_inq call sites. - Run the duplicate-serial check on BOTH paths, not just the declared one: two devices reporting one serial (e.g. /dev/st0 and /dev/nst0) are one drive and can never be a correct configuration. Duplicate entries in OPENBLADE_DRIVE_DEVICES are refused for the same reason. - Refuse at startup when a declared map leaves a drive element with no device: the scheduler sizes itself from the changer, so that element would get a cartridge loaded and strand it at mount. - Typed errors only: sg_inq failures (missing binary, timeout, non-zero rc) and an uncorrelated element now raise DriveCorrelationError with a curated message naming the fix, instead of leaking CommandError/KeyError; connect-i3 prints the message rather than a traceback, and reports correlation warnings. - An empty device list warns instead of raising — connect-i3 is the diagnostic you run *because* no drive appears, so it must still produce a report. - Dry runs cannot apply a serial map (serials need a live probe) and now say so explicitly instead of presenting a positional guess as the plan. Every guard is mutation-checked: disabling it fails a named test. The transposition limitation is pinned by a test so the API cannot quietly start claiming more than it checks. --- docs/hardware-setup.md | 50 +++- openblade/cli/main.py | 9 +- openblade/config.py | 16 +- openblade/hardware/correlation.py | 201 +++++++++++---- openblade/hardware/library.py | 25 +- openblade/hardware/validation.py | 23 +- tests/unit/test_drive_correlation.py | 236 ++++++++++++++++-- tests/unit/test_hardware_validation.py | 2 +- tests/unit/test_real_library_drive_mapping.py | 12 +- 9 files changed, 492 insertions(+), 82 deletions(-) diff --git a/docs/hardware-setup.md b/docs/hardware-setup.md index 24af540..2b13f86 100644 --- a/docs/hardware-setup.md +++ b/docs/hardware-setup.md @@ -46,24 +46,58 @@ OpenBlade therefore correlates the two sides explicitly OPENBLADE_DRIVE_SERIAL_MAP=10WT073820:0,10WT073821:1,10WT073819:2 ``` + ⚠ **The element index is 0-based** — it is `mtx`'s *Data Transfer Element* + number, which you can read straight off `mtx -f /dev/sgN status`.

Parsing I/E elements was right; putting them in `MtxStatus.slots` alongside storage slots was not. `SlotState` carries no is_import_export field, so the distinction is erased at the library.py boundary and every consumer would have started seeing 12 slots where it saw 8. The sharp edge is routes_aml_move_medium.py::_first_empty_slot(), which returns the first UNOCCUPIED slot: on a full library - the normal state of a production library - the first empty element is the operator mailslot, so an unload would eject the cartridge to the front panel. routes_aml_library.py would also have double-counted I/E slots in slotsTotal, on a parity-gated AML response. So `slots` stays "data storage slots you may park or unload a tape into", `import_export_slots` holds the mailslot elements, `all_slots` merges them in element order for anyone who wants both, and `slot_count` - the figure from mtx's own header, which counts both kinds - equals the two lists together. Nothing downstream changes behaviour; the information simply stops being discarded, which was the actual bug.

The unmount wait was added but nothing acted on its result, so the invariant it was supposed to protect was still unenforced - just 60 seconds slower. - `unmount()` computed `device_released` and threw it away: callers marked the drive UNMOUNTED regardless, and `can_unload_drive()` gates purely on that, so an unload could still be green-lit with LTFS holding the drive. Pulling a cartridge then can discard an index that has not been written. Success now MEANS the drive is free, not that umount exited 0. Judging on release also makes retries work: a second call whose umount says "not mounted" reports success once LTFS has gone. - `wait_for_ltfs_release()` failed open. `_ltfs_processes_holding()` swallowed the /proc enumeration error and returned [], so under hidepid, in a container, or as a different uid, "I could not look" read as "released". It now returns None for that case and the wait reports False. For a gate protecting an unload, unknown must not mean safe. - The timeout was 60s of blocking sleep, reachable from an async request handler (routes_ltfs.py). Observed release on the rig is well under a second; 20s is now the bound, named as a constant. - discovery.resolve_sg_device() logs a warning when no sg node can be found instead of silently returning the tape node - that fallback is exactly what produces LTFS's "No index found in the medium", i.e. it looks like bad media rather than a bad device path. Adds the command-level tests review found missing: which argv format_tape and both mount helpers actually build (a RecordingRunner, since the hardware suite can only assert this against a live library), device_list's stderr/exit-1 handling, the unmount gate, and a procfs scan exercised against a real live process named `ltfs`. Four new mutations all caught: dropping resolve_sg_device from the three call sites (4 fail), device_list back to stdout+raise_on_error (1), unmount judging on the exit code (2), unreadable /proc treated as released (1).

Now: barcodes are validated as 6-8 upper-case alphanumerics (all of them, before anything is touched), matched against the WHOLE VolumeTag, and after loading the changer is re-read so the LOADED cartridge's VolumeTag must equal the requested barcode before mkltfs runs. That last step is the positive barcode confirmation AGENTS.md requires; the first two only decide what to load. BLOCKER - reset.sh unloaded drives without checking for a live LTFS mount, against the "never unload while LTFS is mounted or dirty" non-negotiable, in the one new script that issues unloads. Worse because it exists to clean up after FAILED runs, which is exactly when a mount has been left behind. Both it and format-scratch.sh now refuse, list what is holding the drive, and print the command to clear it - unmounting someone else's dirty volume is not a decision a cleanup script should make. Also: - Scripts selected the changer as "first mediumx lsscsi reports". Phase 3 of the bring-up plan cables a real i3 to this same host; a real HBA usually enumerates at a LOWER SCSI host number than mhvtl's dynamic one, and a real Scalar i3 reports the same QUANTUM vendor string. They now key on the rig's unit serial and refuse to guess. Drives are restricted to the changer's SCSI host for the same reason. (mhvtl's Scalar personality prefixes VPD 0x80 with the vendor id, so the serial is compared as its last token, not loosened to a substring.) - setup.sh/teardown.sh claimed to touch only what the rig created; /etc/mhvtl and /opt/mhvtl are mhvtl's OWN defaults and may hold another operator's library. Setup now backs up a pre-existing config before overwriting and moves library_contents.30 aside rather than deleting it; --purge removes only the media barcodes named in our library_contents.10 and restores the backup. - MHVTL_REF pinned to the full 59f32ee SHA instead of `master`: patches/ is byte-exact against it and the recorded results are from that build. Fetch reworked to handle a raw SHA, which `git clone --branch` cannot take. - make_vtl_media's fallback dropped --home-dir, so a failure for an unrelated reason wrote media where nothing else looked. - The patch now carries a header explaining all three defects, the alloc_vpd arithmetic, and the truncation it makes explicit but does not remove. shellcheck -S warning clean. Guards verified against the live rig: partial, suffix and empty barcodes all refused; both scripts refuse while an LTFS mount is held; happy path still formats both scratch tapes with confirmation.

It also never checked + what was actually in the drive before running `mkltfs`. Now: barcodes are + validated as well-formed, matched against the whole VolumeTag, and the drive + is re-read after loading so the **loaded** cartridge's VolumeTag must equal + the requested barcode before anything is written. That last step is the + "positive barcode confirmation" AGENTS.md requires; the first two only decide + what to load. +- **`reset.sh` unloaded drives without checking for a live LTFS mount** — + directly against "never unload while LTFS is mounted or dirty", in the one + new script that issues unloads, and worse because it exists specifically to + clean up after *failed* runs, which is exactly when a mount is left behind. + Both it and `format-scratch.sh` now refuse and tell you how to clear it. +- **`unmount()` computed `device_released` and discarded it** — callers marked + the drive `UNMOUNTED` regardless, so `can_unload_drive()` would green-light + an unload with LTFS still holding the drive. The wait was a 20-second pause + that changed nothing. Success now *means* the drive is free. +- **`wait_for_ltfs_release()` failed open** — an unreadable `/proc` (hidepid, a + container, a different uid) read as "released". For a gate protecting an + unload, "I could not look" must not mean "safe". +- **Scripts selected the changer as "first `mediumx`"** — Phase 3 cables a real + i3 to this same host, a real HBA usually enumerates below mhvtl's dynamic + host number, and a real Scalar i3 reports the same `QUANTUM` vendor string. + They now key on the rig's unit serial and refuse to guess. +- **`setup.sh`/`teardown.sh` were not as well-scoped as their comments claimed.** + `/etc/mhvtl` and `/opt/mhvtl` are mhvtl's own defaults, not paths this rig + invented.

+0000 Subject: [PATCH 029/110] fix(cli): honour OPENBLADE_BACKEND instead of always simulating `_default_config()` constructed `OpenBladeConfig()` directly, so every CLI command ran against the simulator regardless of the environment. On the mhvtl rig `openblade inventory` printed a 50-slot library of VOL0nnL9 barcodes while the real library holds 8 slots of OB000nL8 -- plausible, wrong, and silent. Its hardcoded db/cache/staging/restore paths were already identical to `load_config()`'s defaults, so this is a pure widening. Two consequences of that fix are handled here too: * `mock_state.json` is a snapshot of simulator internals. `_save_state` now skips a real context (it would AttributeError on backends that have no `_drives`), and `_load_state` refuses to overwrite a live library with a simulation -- the more dangerous direction. * `mock init` pins BackendMode.MOCK explicitly, so it cannot reach for a real changer just because the shell exports one. * A state file written by an older release used to traceback on every command with no documented recovery. It is now moved to .stale with an explanatory message and re-seeded. All four guards mutation-checked: each reverted individually, the named test confirmed failing, then restored.

The safety line is structural, not prompt-level. Three independent guards: - readonly.py wraps CatalogRepository and LibraryBackend in attribute allowlists, so a tool body cannot reach a write method at all. - tools.py refuses to build a registry containing a name that is not on READ_ONLY_TOOL_NAMES, so a future tool addition fails closed. - session.py has no subprocess, no DB session and no write path; it can only call handlers the registry accepted. Every upstream failure (timeout, connect, 4xx/5xx, non-JSON, missing message) is normalized to a curated AssistantUpstreamError; raw socket and provider text is dropped, never wrapped. scalar_password is reduced to a boolean at the tool-context boundary so no tool can surface it, and the DB URL is reported by scheme only.

Tool calls are shown as dim single lines so the operator can see what was consulted. Lives in its own module so the assistant's dependencies stay out of main.py; the command is registered with app.command(). An unconfigured assistant exits 1 with the setup instructions before touching the database. No API endpoint in v1 — tracked as follow-up.

Walking it finds 469 of the 1171 operations and silently drops every native surface. The generator reads `app.openapi()` instead. * Typer 0.27 vendors its own click fork, so a `TyperGroup` is not a `click.Group`. An isinstance check collapses the whole command tree to one leaf without raising. The walk is duck-typed on `.commands`. The ~980-operation Quantum AML/iBlade surface is counted, not expanded: it is a separate wire contract with its own generated catalog, which api.md links to. Staleness detection was mutation-checked: adding a command to the Typer app turns 3 of the 5 tests red, and removing it turns them green again. --- docs/wiki/reference/api.md | 337 +++++++++++++ docs/wiki/reference/cli.md | 139 ++++++ tests/unit/test_wiki_reference_generated.py | 85 ++++ tools/gen_wiki_reference.py | 516 ++++++++++++++++++++ 4 files changed, 1077 insertions(+) create mode 100644 docs/wiki/reference/api.md create mode 100644 docs/wiki/reference/cli.md create mode 100644 tests/unit/test_wiki_reference_generated.py create mode 100644 tools/gen_wiki_reference.py diff --git a/docs/wiki/reference/api.md b/docs/wiki/reference/api.md new file mode 100644 index 0000000..b249123 --- /dev/null +++ b/docs/wiki/reference/api.md @@ -0,0 +1,337 @@ + + +# HTTP API reference + +Introspected from the OpenAPI schema of `openblade.api.main:app`. + +**1171 operations** total: 191 on the native OpenBlade control plane, 980 on the Quantum AML / iBlade emulator surface. + +The application serves two surfaces from one ASGI app. Setting +`OPENBLADE_SCALAR_API_ONLY=true` puts it in emulator-only mode, where the +native surfaces below return 404. + +Interactive docs for a running instance are at `/docs` and `/redoc`. + +## Native OpenBlade control plane + +### `health` (7 operations) + +| Method | Path | Summary | Parameters | Request | Response | +| --- | --- | --- | --- | --- | --- | +| `GET` | `/error-codes` | Get Error Codes | - | - | `ErrorCodesResponse` | +| `GET` | `/healthz` | Get Health | - | - | `HealthResponse` | +| `GET` | `/readyz` | Get Ready | - | - | `ReadyResponse` | +| `GET` | `/status/catalog` | Get Catalog Status | - | - | `CatalogStatusResponse` | +| `GET` | `/status/library` | Get Library Status | - | - | `openblade__nas__types__LibraryStatusResponse` | +| `GET` | `/system/config-summary` | Get System Config Summary | - | - | `SystemConfigSummaryResponse` | +| `GET` | `/version` | Get Version | - | - | `VersionResponse` | + +### `inventory` (1 operation) + +| Method | Path | Summary | Parameters | Request | Response | +| --- | --- | --- | --- | --- | --- | +| `GET` | `/inventory/` | Get Inventory | - | - | `InventoryResponse` | + +### `cartridges` (3 operations) + +| Method | Path | Summary | Parameters | Request | Response | +| --- | --- | --- | --- | --- | --- | +| `GET` | `/cartridges/` | List Cartridges | - | - | `CartridgeResponse[]` | +| `POST` | `/cartridges/format/confirm` | Format Confirm | - | `FormatConfirmRequest` | `OperationResponse` | +| `POST` | `/cartridges/{barcode}/format/dry-run` | Format Dry Run | `barcode` (path) | - | `DryRunResponse` | + +### `tape-ops` (3 operations) + +| Method | Path | Summary | Parameters | Request | Response | +| --- | --- | --- | --- | --- | --- | +| `GET` | `/tape-ops` | List Tape Ops | `barcode`?

Coverage: disabled-config path and the curated setup message; the tool loop round-trip (model asks get_inventory, gets real seeded state back, answers); loop bound; string-encoded tool arguments; unknown-tool handling; every tool against a seeded volume group, two tapes, two archived files and two jobs; search_docs against docs/safety.md and a nested tree; curated upstream errors for timeout/connect/401/404/429/500/418/non-JSON/error-field, each asserting the raw provider text is absent; and DSN/scalar-password redaction. Safety suite mutation-checked, both guards: - remove the registry allowlist check -> test_registry_guard_rejects_a_ mutating_tool fails (1 failed, 40 passed). - remove the ReadOnlyProxy attribute check -> 11 failures across the catalog-write and media-move cases (11 failed, 30 passed). Restored: 41 passed.

c23b0f11b4ca15465655b1ac4f21fa6893d49372 Mon Sep 17 00:00:00 2001 From: Hermes Agent Date: Fri, 11 Sep 2026 16:18:04 +0000 Subject: [PATCH 034/110] fix(tape-ops): load the cartridge before formatting; log the real failure cause Two defects on the primary destructive path, both found by running `openblade format confirm` against the mhvtl rig. 1. `_format` called `ltfs.format(barcode, ...)` without ever loading the cartridge. mkltfs runs against a drive node, so every format of a cartridge sitting in its slot -- the normal state -- failed with "Barcode OB0001L8 is not loaded in a drive". `MockLTFSBackend.format` only needs a barcode, which is exactly why the simulator never showed it. `_format` now uses the same `_ensure_loaded` + only-put-back-what-we-took-out discipline as `_write`, including on the failure path, so a failed format cannot strand a cartridge in a drive. The confirmation gate is untouched. 2. The operator saw none of that. The orchestrator sanitises the exception into a constant per-op-type string -- correct, it crosses a trust boundary -- but it also logged only that sanitised string, so the cause existed nowhere on the host. The persisted/returned `error` is unchanged; the server log now carries cause_type, cause and a traceback. Also: structlog's default PrintLoggerFactory writes to sys.stdout (verified in the installed structlog source), so those same log lines corrupted the CLI's own JSON -- `openblade format confirm ... | jq` failed with "Extra data". Logs now go to stderr. Plus one dead assignment ruff was already flagging on master. Five regression tests, all mutation-checked: format-with-no-load, format-with-no- unload (2 tests), cause-dropped-from-log, and logs-back-on-stdout each revert to a failing named test. Verified live: 6 cartridges formatted through the CLI against real LTFS 2.4.8.4, all returned to slots, stdout pure JSON.

By then the mount point is an ordinary empty directory, so the walk returned 0 -- and 0 is what `jobs/archive.py:240` then wrote back to the cartridge row. Measured on the mhvtl rig before this change: after write : cap=12000000000 used=5242880 remaining=11994757120 after unmount: cap=12000000000 used=0 remaining=12000000000 So OpenBlade believed every tape was empty after every archive job, and `_choose_tape` -- whose entire job is to roll to the next tape when this one is full -- could never fire. It kept selecting a tape it thought was empty until the LTFS write returned ENOSPC. The hardcoded 12,000,000,000 made it worse: an 8000 MB cartridge measures 6,569,328,640 after LTFS partitioning, so free space was over-reported by 83% even on a genuinely blank tape. Capacity and usage now come from `statvfs` on the live mount, taken *before* the umount runs. That is one syscall instead of an O(files) stat storm after every single write, and it reports the medium's real geometry. After the change, same probe: after write : cap=6569328640 used=22020096 remaining=6547308544 after unmount: cap=6569328640 used=22020096 remaining=6547308544 A tape this process has never mounted still assumes 12 GB -- there is nothing to measure until it is mounted. That is now the only remaining over-report and is recorded in the campaign runbook rather than papered over with a config knob. Three regression tests, mutation-checked: reverting to the directory walk fails all three; reverting only the measure-before-umount ordering fails the ordering test specifically.

Written for an operator who has the hardware but not the codebase. Accuracy method, since these pages make load-bearing claims: * Every CLI invocation in the wiki is validated against the live Typer app — command exists, is not a group, and every flag is real. No invented flags. * The simulator round trip in getting-started.md is a transcript: mock init, inventory, format dry-run/confirm, volume-group, archive, catalog, restore, jobs were all executed and the output pasted. * Every endpoint path cited is cross-checked against app.openapi(). The only two misses are deliberate: both cite /metrics to say it does NOT exist. * Request-body field names were read from the schema, not guessed. Where the code disagrees with an existing doc, the guide documents the code and says so. The substantive ones, each verified at the source: * POST /ltfs/format with {"confirm": true} formats a tape with no dry run, no safety token and no auth — confirmed empirically. docs/safety.md states the token is required. * The unload-while-mounted guard exists only in the simulator backend; RealLibraryBackend.unload has no such check. * JobQueue.claim_drive/claim_changer are never called — two of the eight gates in docs/safety.md are not implemented. * Archive and restore are synchronous; the API's 202/"pending" is a literal. * The CLI ignores OPENBLADE_DB_URL, so CLI and server can use different DBs. * catalog rebuild-from-tape does not recover file_records/file_instances/ volume_groups at all — the classic archive catalog is backup-only. * docs/sharding.md and docs/diagrams/shard-design.md describe ~20 behaviours that were never built; archiving.md tabulates them rather than repeating them. * Nothing is FUSE-mountable and neither the SMB nor the NFS helper is referenced by any code. docs/wiki/guides/assistant.md is deliberately absent — owned elsewhere. --- README.md | 2 + docs/wiki/README.md | 109 +++++++ docs/wiki/guides/archiving.md | 211 ++++++++++++ docs/wiki/guides/drives-and-changer.md | 343 ++++++++++++++++++++ docs/wiki/guides/formatting-tapes.md | 171 ++++++++++ docs/wiki/guides/fuse-and-nas.md | 167 ++++++++++ docs/wiki/guides/getting-started.md | 264 +++++++++++++++ docs/wiki/guides/hardware-bring-up.md | 105 ++++++ docs/wiki/guides/inventory-and-barcodes.md | 138 ++++++++ docs/wiki/guides/jobs-and-monitoring.md | 180 ++++++++++ docs/wiki/guides/restoring.md | 165 ++++++++++ docs/wiki/guides/safety-model.md | 190 +++++++++++ docs/wiki/guides/the-catalog.md | 194 +++++++++++ docs/wiki/guides/troubleshooting.md | 307 ++++++++++++++++++ docs/wiki/guides/volume-groups-and-pools.md | 191 +++++++++++ 15 files changed, 2737 insertions(+) create mode 100644 docs/wiki/README.md create mode 100644 docs/wiki/guides/archiving.md create mode 100644 docs/wiki/guides/drives-and-changer.md create mode 100644 docs/wiki/guides/formatting-tapes.md create mode 100644 docs/wiki/guides/fuse-and-nas.md create mode 100644 docs/wiki/guides/getting-started.md create mode 100644 docs/wiki/guides/hardware-bring-up.md create mode 100644 docs/wiki/guides/inventory-and-barcodes.md create mode 100644 docs/wiki/guides/jobs-and-monitoring.md create mode 100644 docs/wiki/guides/restoring.md create mode 100644 docs/wiki/guides/safety-model.md create mode 100644 docs/wiki/guides/the-catalog.md create mode 100644 docs/wiki/guides/troubleshooting.md create mode 100644 docs/wiki/guides/volume-groups-and-pools.md diff --git a/README.md b/README.md index 786ac58..1f09304 100644 --- a/README.md +++ b/README.md @@ -2,6 +2,8 @@ OpenBlade is a simulator-first DIY tape archive controller inspired by iBlade-style workflows for Quantum Scalar i3 and LTFS media handling.

The simple one writes files to one tape at a time and +is reachable from the CLI. The sharded one writes across several tapes and +drives in parallel and is **API-only**.

Pick a tape — see [volume groups & pools](volume-groups-and-pools.md). Tape + selection is per file, first-fit in barcode order. +2. Load it into a free drive if it is not already loaded; mount `READ_WRITE`. +3. Write the file; record a `file_record` (logical path, size, SHA-256) and a + `file_instance` (barcode + tape path), initially `pending`. +4. When the next file needs a different tape: unmount, flip that tape's pending + instances to `archived`, unload, update `used_bytes`, commit. + +Catalog path = `//`. The +source directory's own name is not included. + +### It is synchronous + +`openblade archive` blocks until the whole job finishes. `POST /archive/` +likewise runs the job **inside the request handler**, then returns +`202 Accepted` with `"status": "pending"` — which is a hardcoded literal, not the +real state. Verified: a `202 … "pending"` response was followed immediately by +`GET /jobs/` showing that job already `completed`. + +Practical consequences: expect long-running HTTP requests, set generous proxy +timeouts, and poll `GET /jobs/{id}` for the truth. + +All archive requests are serialised by a single process-wide lock, so two +concurrent archives queue rather than fight over drives. + +### Failure behaviour + +There is **no retry**. On any exception the job is marked `failed` with the +exception text, the drive is best-effort unmounted and unloaded, and catalog +rows for files that never reached tape are deleted. Tapes already finalised +earlier in the run keep their archived files. + +`dry_run=True` on the core engine returns `tapes_used: []` and marks the job +completed **without consulting any tape**.

Nothing is split; each file is one shard. +- Files are processed in batches of exactly `lane_count`; one batch = one + parallel write round = one atomic commit unit. +- Tape path: `/stripe/`. + +Because assignment is positional, a file's lane **changes** if files are added to +or removed from the source directory. Re-archiving is not lane-stable. + +### `block_stripe` — one file's bytes across lanes + +- The whole-file SHA-256 is computed up front. +- The file is cut into `block_size` blocks (default **128 MiB**) and blocks are + assigned round-robin: `lane = block_index % lane_count`. +- **One shard per lane**, not one per block: each shard is the concatenation of + all blocks belonging to that lane. +- Tape path: `/block_stripe//.shardNNNN`. + +Two operational costs to budget for: + +- Each shard is first written to a **temporary full copy on local disk**, under + `./.openblade-scratch/archive-` — *relative to the process working + directory*. You need roughly 1× the source file in free local space. +- Each of the N workers **re-reads the entire source file** to pick out its own + blocks. Throughput will not approach N× a single drive's rate. + +### Commit is atomic per unit + +The protocol, in order: + +1. Write every shard/file in the unit, and checksum-verify each one. +2. Create catalog rows — instances start as `pending`. +3. Unmount every tape and unload every drive, **aggregating all failures**. +4. Only now flip the instances to `archived`. + +If step 3 fails, the data is on tape but the commit does not happen, and the job +error reads: + +``` +shards written but physical state is unknown (reconcile required): … +``` + +That is deliberate: a dirty unmount or a stuck unload blocks the commit even +though the bytes wrote fine. + +On mid-archive failure, staged instances stay `pending` forever. They are never +selected for restore, so the catalog never claims data it cannot serve — but +there is **no rollback, no erase, no retry and no repair job**. Bytes may sit on +tape unreferenced. + +Commit granularity: `stripe` commits **per batch of `lane_count` files**; +`block_stripe` commits **per file**, and a failure on one file does not stop the +loop. Terminal job state is `completed` if there were no errors, otherwise +`failed_recoverable`. + +### Concurrency caveat + +A `DriveScheduler` is constructed **per HTTP request**, not shared. Archive is +saved by the process-wide archive lock. Restore has no equivalent lock, so +concurrent sharded restores can each believe they own the same drive. +`docs/sharding.md`'s invariant "DriveScheduler never grants the same drive to two +jobs" holds only within one scheduler instance. + +### Checking the result + +``` +GET /catalog/{file_id}/shards # the child records for a sharded file +GET /jobs/{job_id} +``` + +--- + +## 3.

See +[drives & changer ops](drives-and-changer.md). + +**Operator rule:** on real hardware, never script an unload immediately after an +unmount without checking the unmount result's `device_released` field. + +## 4. The drive ownership gate ❌ + +`JobQueue.claim_drive()` is **never called by any production code**. A `JobQueue` +is constructed at startup and handed to the services; none of them use its +ownership methods, and its state never reaches the database. + +What actually serialises drive access: + +- a process-wide lock around **archive** requests (not restores), +- the orchestrator's per-drive lock for write and format, and per-barcode lock + for read and verify, +- `DriveScheduler` for sharded jobs — real, but constructed **per HTTP request**, + so two concurrent requests hold independent lock tables. + +## 5. The changer ownership gate ⚠️ + +`JobQueue.claim_changer()` is likewise never called. The simulator does serialise +the changer with a non-blocking lock (`ChangerBusyError: Changer is already +moving media`). The real backend has no equivalent; it trusts `mtx`. + +Load, unload, move and eject take **no orchestrator lock at all**. + +## 6. The archive completion gate ⚠️ + +The **sharded** engine genuinely implements it: every shard is checksum-verified, +then every tape is cleanly unmounted and unloaded with all failures aggregated, +and only then are catalog instances flipped from `pending` to `archived`. A dirty +unmount blocks the commit even though the bytes wrote fine, with the error +`shards written but physical state is unknown (reconcile required)`. + +The **classic** engine is weaker: it writes catalog rows per file and, on +failure, deletes rows for files that never reached tape.

From 2892e67d0218954a18821a4075a5cb05c3e30827 Mon Sep 17 00:00:00 2001 From: Hermes Agent Date: Fri, 11 Sep 2026 16:32:46 +0000 Subject: [PATCH 039/110] fix(archive): a full tape is not a valid home for a zero-byte file Archiving the campaign dataset (1,073 files, 430 MB) onto 95 MiB tapes died part way through with a raw traceback: OSError: [Errno 28] No space left on device: '/srv/openblade-campaign/ltfs/OB0001L8/campaign-plain/logs' after 617 of 1,073 files. `_choose_tape` asked `remaining_capacity(barcode) >= size_bytes`, which is True for `0 >= 0`, so once the first tape was full every *empty* file in the tree was routed straight back onto it. An empty file still needs a directory entry and index space, so LTFS answered ENOSPC -- and because it surfaced as an OSError rather than a capacity decision, the job aborted instead of rolling to the next tape. `_has_room_for()` now treats a tape with zero remaining capacity as unusable for anything, empty or not. Four regression tests; reverting to the bare `>=` comparison fails two of them. After the fix the same archive completes: 1,073 records / 450,492,947 bytes across five tapes, spillover working. Also lands the campaign harness: env.sh, the phase runner, restore_and_verify.py, and set_media_capacity.sh (rig-only -- it shrinks mhvtl's virtual cartridges so a 430 MB dataset actually overflows one, which is how the bug above was reached). The dataset generator now emits both a resolvable and a dangling symlink, since the product treats them differently and the runbook has to say how.

Each fix below was re-verified at the source before being applied. 1. The CLI is simulator-only, and two guides used it as a hardware check. _default_config() (cli/main.py:39) never calls load_config(), so the backend stays mock and OPENBLADE_DB_URL is ignored. Only `hardware connect-i3` and `hardware validate-ltfs` read the real config. Proven: under OPENBLADE_BACKEND=real + REAL_HARDWARE_ENABLED=true, `openblade inventory` exits 0 printing simulator cartridges. safety-model.md step 6 was telling operators to use exactly that as their read-only pre-flight check. Now warned in getting-started §5, safety-model step 6, and in the GENERATED cli.md header so it cannot drift out. 2. `openblade format confirm` cannot format real media but reports success. formatting-tapes.md recommended it for "anything an operator drives". Scoped to the /cartridges pair with a banner at the top of the page. 3. The quarantine advice was inverted for the mainline restore path. jobs/restore.py:166 writes a PERSISTENT `.quarantine` in the operator's destination directory; only sharded_restore.py:168 uses the scratch dir that is later deleted. The guide documented the sharded path and told operators to treat a failure as "nothing was produced" — which would leave corrupt data sitting in a production restore target. Split into three rows + cleanup instruction. Also: sharded archives catalog files under their RAW ABSOLUTE SOURCE PATH (sharded_archive.py:284,428), not //... — so the group-prefix "invariant" asserted in four pages is a property of the simple engine only. Verified and corrected in archiving, restoring, volume-groups, the-catalog. Generator hardening (same review): build_pages() now pins the introspection environment. Previously OPENBLADE_SCALAR_API_ONLY=true regenerated api.md with every native route missing, and OPENBLADE_BACKEND=real — which the bring-up guides tell operators to set — made the staleness test ERROR with RealHardwareDisabledError. Importing the app also seeded demo rows into the operator's real ~/.openblade/openblade.db, the same file the CLI reads; the DB URL is now redirected to a temp file. Both hostile environments verified green, and no ~/.openblade is created. assert_app_surface_is_complete() is the backstop for the case where the app was already imported by another test. Plus nits: /health returns {"status":"ok","backend":"mock"}; the classic checksum error string; DriveBusyError blocks 300s when drives are merely busy rather than failing fast; phase-2 tape selection commits cartridge rows for tapes it then rejects. --- docs/wiki/guides/archiving.md | 10 +++ docs/wiki/guides/formatting-tapes.md | 18 ++++- docs/wiki/guides/getting-started.md | 46 +++++++++--- docs/wiki/guides/jobs-and-monitoring.md | 2 +- docs/wiki/guides/restoring.md | 53 +++++++++---- docs/wiki/guides/safety-model.md | 14 +++- docs/wiki/guides/the-catalog.md | 10 ++- docs/wiki/guides/volume-groups-and-pools.md | 17 ++++- docs/wiki/reference/cli.md | 9 +++ tools/gen_wiki_reference.py | 83 ++++++++++++++++++++- 10 files changed, 224 insertions(+), 38 deletions(-) diff --git a/docs/wiki/guides/archiving.md b/docs/wiki/guides/archiving.md index 72aaeef..4da55c2 100644 --- a/docs/wiki/guides/archiving.md +++ b/docs/wiki/guides/archiving.md @@ -84,6 +84,16 @@ POST /archive/sharded sharded archives, and `openblade restore` cannot correctly restore them** — it does not replicate the shard detection that the API does. +### ⚠️ Catalog paths are NOT group-prefixed here + +Unlike the simple engine, the sharded engine catalogs each file under its **raw +absolute source path** — `/data/big/note.txt`, not `/shard-vg/note.txt` — even +though it does assign the lane tapes to the volume group.

The checksum guard then turns that into a clean failure -- that part is deliberate and correct -- but its message is "tape read failed or data corrupt", which points the operator at the cartridge. Against real hardware the actual cause is almost always "Barcode ... is not loaded in a drive": HydrationExecutor never calls `library.load()`, so `RealLTFSBackend.read_bytes` -> `mount` raises before it touches the medium. The operator was being told their tape was corrupt when the tape was simply still in its slot. The cause is now logged with a traceback; the fallback and the guard are unchanged. Regression test mutation-checked: restoring the bare `except Exception` fails it. Also: restore_and_verify.py now classifies a dereferenced symlink as its own outcome rather than a checksum mismatch, and reports manifest entries that were never archived at all -- which is how the silently-skipped dangling symlink shows up.

MUST-FIX, both proven with repros: - ReadOnlyProxy leaked the live object. __getattr__ only runs when normal lookup FAILS, and __slots__ creates class-level descriptors found by normal lookup — so proxy._target returned the real CatalogRepository, hence .session, hence .commit(). The proxy now keeps no instance state at all (module-private WeakKeyDictionary) and filters every access through __getattribute__; _target, __class__, __dict__, __reduce__ are all refused. - __setattr__ was not enough: __init__ was reachable and uses object.__setattr__ internally, so proxy.__init__(evil, {...}, "catalog") re-pointed the proxy at an arbitrary object with an arbitrary allowlist. Now refused like any other attribute. Also fixed: - httpx.InvalidURL is not an httpx.HTTPError, so a scheme-less OPENBLADE_OLLAMA_URL escaped the curated-error contract as a traceback. - Model replies containing "[/x]" raised rich MarkupError and killed the REPL; all console output is now markup-free. - A failed turn left an assistant message with unanswered tool_calls plus a dangling tool message in the transcript. ask() now rewinds on error. - catalog_search loaded the whole catalog into memory and filtered in Python on a model-chosen pattern. It now narrows in SQL via the existing list_catalog_files (glob patterns contribute their literal prefix), caps the scan at 500 rows, reports scanTruncated, and resolves volume-group names from one map instead of an N+1 lazy load. - search_docs treated "#" inside fenced code as a heading, shredding docs/sharding.md into fragments attributed to headings that do not exist. - Tool calls are now capped at 8 per round; only rounds were bounded before. - Secrets are redacted at build_context rather than at output, ToolContext no longer stores a raw DSN, and config is repr=False so a traceback with locals cannot print the Ollama API key. - A long-lived REPL session pinned rows in SQLAlchemy's identity map; each turn now expires them first so reads reflect other processes' commits. - docsRoot no longer ships the operator's absolute home path to the model.

Now rglob, plus an explicit file list so a new module fails the suite until it is reviewed and named. Added: - proxy escape probes as parametrized cases: _target, _allowed, __class__, __dict__, __init__, __reduce__, __reduce_ex__, __getstate__, __getattribute__ — none of which were covered, which is why the leak shipped green. Plus re-initialisation, copy and pickle. - forbidden imports extended from stdlib-only to OpenBlade's acting subsystems: hardware (SafeRunner shells out), jobs, safety, fuse, sftp, simulator. - regressions for each fix: InvalidURL curation, transcript rewind on a failed turn, the per-round call cap, SQL-bounded catalog_search, fence-aware doc splitting, no absolute docs path, refresh wiring, and repr redaction.

failed jobs recorded no reason Two defects, both found by running a sharded archive of real data. 1. DATA LOSS. STRIPE wrote every file to `/stripe/{basename}` -- one flat namespace. Two files with the same name in different source directories that landed on the same lane wrote to the same on-tape location; the second silently overwrote the first, and BOTH were marked `archived`. Demonstrated on the rig: /srv/.../collide/alpha/same.txt sha 0020e5d47ac5 OB0001L8:/stripe/same.txt /srv/.../collide/beta/same.txt sha 502c24866d7f OB0001L8:/stripe/same.txt Restoring alpha returned beta's bytes; only the restore-time checksum verify caught it, long after the operator would have considered the source safe. `_stripe_tape_path()` now mirrors the source tree under /stripe, the way the non-sharded path already mirrors it under the volume group. Re-verified on the rig: both files now round-trip to their own bytes. Existing media are unaffected -- restore reads `file_instances.tape_path` as stored rather than recomputing it. 2. A sharded archive that failed collected one message per failed batch into a list that was returned in ShardedArchiveResult and nowhere else. The API route discards the result (it answers {job_id, status:"pending"}), and `update_job_state` was called without an error. The first full run wrote 3 of 1,073 files over ten minutes and surfaced as `failed_recoverable` with `error: null` and not one log line -- there was no way to find out why. The per-batch handler now logs with a traceback, and a bounded, de-duplicated summary is persisted on the job. Four regression tests, mutation-checked: restoring the flat tape path fails the collision and round-trip tests; dropping the error summary fails the job-error test.

On the rig: POST /tape-ops/execute {"op_type":"move","barcode":"OB0003L8", "slot_id":3,"extras":{"dest_slot_id":9}} -> 200, and mtx status showed Storage Element 9 IMPORT/EXPORT:Full :VolumeTag=OB0003L8 No confirmation, no warning, no safety token. That cartridge held 358 archived files, and `inventory()` reports data storage slots only -- deliberately, see hardware/mtx.py -- so after the move OpenBlade could not see the tape at all. `openblade inventory` showed slot 3 empty and no OB0003L8 anywhere. Every file on it became unrestorable ("Barcode not found in inventory"). One unconfirmed integer orphaned a third of an archive. Moving media out of the library is an export, and the product's position on export is already explicit: routes_aml_move_medium rejects moveClass import/export on i3/i6 with 422. The orchestrator now agrees -- a destination outside the library's own storage slots is rejected during validation, naming the valid range. Verified live: the same request now returns 400 and the cartridge stays in slot 3. Two regression tests, mutation-checked: removing the guard fails the refusal test, and the ordinary slot-to-slot move still passes.

The FUSE and import/export sections say 'does not exist' rather than 'could not be tested': this host has /dev/fuse and fusermount3, so that is a product gap, not an environment one.

Useless where it matters. | +| `GET /status/catalog` | API | Reported `total_file_records: 0` while the catalog held 1,075 — it counts NAS `nas_file_records`, a different table. | +| `GET /dashboard/stats` | API | `totalAssignedTapes: 0`, `totalTapeCapacityBytes: 0` after archiving 450 MB (see below). | +| `GET /volume-groups/` | API | Every group reports `barcodes: []`. | +| `GET /cartridges/` | API | Every cartridge reports `formatted: false` after being formatted through the product — the format path never writes the flag back. | +| Cartridge write-back, sharded path | `jobs/sharded_archive.py` | After a full sharded archive, **no cartridge row has a `volume_group_id`, `used_bytes` or `capacity_bytes`**. The non-sharded path does this at `archive.py:240`; the sharded path does not. This is what empties the four surfaces above, and it means a second sharded archive onto the same lanes treats them as blank. | +| Spillover, sharded path | `jobs/sharded_archive.py` | No capacity check and no roll-to-next-tape at all. On 95 MiB cartridges the 430 MB dataset failed every batch. A lane filling up is a raw `ENOSPC` in `errors[]`, not a tape change. | +| Catalog namespace, sharded path | `jobs/sharded_archive.py` | Records are keyed on the **absolute source path** (`/srv/…/data/x.bin`), not `/{volume_group}/{relative}` as the non-sharded path does. The volume group is not part of the key, so archiving the same source twice in different modes **merges into one record with mixed instances** — observed when `bigblob.dat` was archived STRIPE then BLOCK_STRIPE. | +| `/nas/fuse/open` | API | Returns `{"action":"queue_hydration","message":"File is offline. Hydration queued."}` — nothing is queued. No restore job, no executor, no queue append. The message is untrue. | +| `POST /nas/datasets/{id}/export` | API | Flips two database columns to EXPORTED. No robot, no tape op, no audit record. The tape does not move; the catalog then claims the data left. | +| `TapeOpType.EJECT` | none | Never constructed anywhere, and non-functional if constructed: no library backend defines `eject`, so it silently falls through to an unload into a storage slot. | +| `GET /catalog/seed-demo` | API | Shadowed by `GET /catalog/{file_id}`, declared earlier — always 404s as `file_id="seed-demo"`. | +| `Dockerfile` `OPENBLADE_BACKEND=simulator` | container | Not a valid `BackendMode`; `load_config()` catches the `ValueError` and silently falls back to `mock`. | + +### Does not exist + +| Function | Status | +|---|---| +| **FUSE / NAS mount** | **No FUSE filesystem exists.** No `fusepy`/`pyfuse3`/`llfuse` in `pyproject.toml`; grepping the tree for them returns nothing. `CatalogFilesystem` is a plain 98-line in-process object whose only production consumer is `openblade catalog`. There is no mount command, entrypoint, or unit file. **This is not an environment limitation** — this host has `/dev/fuse` and `fusermount3 3.10.5` available; the feature is simply unimplemented. `docs/fuse.md` says so ("a lightweight namespace abstraction… so future kernel FUSE work can reuse the same contracts"). | +| **Import / export (I/E slot) flows** | No CLI command, no native REST route, nothing in `openblade/hardware/`. `MtxStatus.import_export_slots` is parsed and has **zero consumers**. The AML surface returns 422 for import/export moveClass on i3. The only way to reach an I/E element was the unvalidated `dest_slot_id` of defect 3.9, now closed. | +| **Bulk / directory restore** | `openblade restore` and `POST /restore/` take one catalog path. There is no "restore this volume group" anywhere. The NAS hydration path does bulk work but is pool/dataset-scoped and never populated by the archive jobs. `scripts/campaign/restore_and_verify.py` loops because it has to. | +| **CLI load / unload / move on a real library** | `openblade mock load` / `mock unload` are simulator-only (and now explicitly pinned to `BackendMode.MOCK`). Real media movement is API-only, through `POST /tape-ops/execute`. | +| **CLI sharded archive** | API only. | +| **Drive health / TapeAlert** | No native route. Drive state comes from `/inventory/` and `/status/library`. The rehearsal already recorded that mhvtl does not emulate TapeAlert, so this stays unexercised until the i3. | +| **`WRITE` / `READ` / `VERIFY` tape ops** | No dedicated CLI command or route; reachable only by hand-crafting a `/tape-ops/execute` body. | +| **Virtual namespace over archived data** | `GET /virtual/ls?path=/` returns `{"entries":[],"total_entries":0}` after archiving 450 MB. The NAS namespace is dataset-backed and the archive jobs never create datasets — the two halves of the product are not connected. | + +--- + +## 5. Behaviours worth knowing (not defects) + +- **Symlinks are dereferenced.** A resolvable symlink is archived as a regular + file holding the target's bytes; the link is not preserved. Restoring it + produces a file, not a link. +- **A dangling symlink is silently skipped.** No warning, no error, no entry in + the job result — the job reports `completed` with a file count that is quietly + lower than the source tree. In this campaign: 1,073 archived from 1,074 + entries. +- **Restore to a directory uses the basename only.** `openblade restore --to + /some/dir` writes `/some/dir/{basename}`, so restoring a tree into one + directory collapses same-named files from different subdirectories. Pass an + explicit per-file destination (what the campaign verifier does). +- **`RealLTFSBackend.write_file` reads the whole file into memory** + (`source.read_bytes()`). The 120 MB blob was fully buffered. For a product + targeting multi-TB media this is a scaling limit worth a look. +- **A tape this process has never mounted still assumes 12 GB.** There is nothing + to measure until it is mounted, so `_choose_tape` can pick an over-estimated + tape on the first file after a restart. Left as-is rather than papered over + with a config knob; recorded here instead. +- **Single-file restore load/unloads per file.** 1,073 restores produced ~1,073 + load/unload pairs. 612 s on mhvtl; on a real i3, where a tape change is + measured in tens of seconds, a full restore of this shape is impractical. This + is the strongest argument for a bulk restore path. +- **STRIPE batching is chatty.** One batch of *lane_count* files does + load + mount + write + unmount + unload on every lane. 1,073 files over 3 lanes + produced 358 batches and ~2,166 robot moves. + +--- + +## 6.

From 831be6d99753cff429d285ab07fd5c764e6715a5 Mon Sep 17 00:00:00 2001 From: Amantux Date: Fri, 11 Sep 2026 17:36:50 +0000 Subject: [PATCH 047/110] fix(assistant): go through InventoryService, satisfying SAFETY_003 The full suite caught a real violation: tests/safety/test_import_guard.py failed on this branch (and passes on master) because the assistant called `context.library.inventory()` directly, which the SAFETY_003 static guard forbids outside the authorized hardware access points. The right fix was not to widen the guard's allowlist. `InventoryService` already existed on AppContext, is what the API uses, and lives in a module the guard already permits -- the assistant had simply bypassed it. This is the "grep for it first" case: a bypassed policy and a missing policy look identical from the symptom side. The assistant now receives InventoryService, never the LibraryBackend, so load/unload/move/eject are not merely un-allowlisted -- they are not attributes of the wrapped object at all. The proxy allowlist narrows from {"inventory"} to {"snapshot"}. Verified: import guard green; 114 assistant tests green; all three guards still mutation-checked (registry 1F/62P, proxy 26F/37P, rogue subpackage 4F/59P, restored 68P); end-to-end CLI smoke against a stub Ollama still returns grounded inventory.

Two defects in the fix itself, both found by probing it rather than reading it: * `Path.relative_to` does not normalise, and `source_root` arrives straight from the API body (`POST /archive/sharded {"source_path": ...}`). `/data/../etc/passwd` relative to `/data` gave `../etc/passwd`, which `write_file` joins onto the mount point -- escaping /stripe, and with enough `..` escaping the LTFS mount onto the host filesystem. * `relative_to(itself)` returns `Path(".")` rather than raising, so a single-file source collapsed the tape path to a bare `/stripe`, a directory rather than a file. The earlier single-file test passed only because MockLTFSBackend accepts any path string. Normalised lexically with `os.path.normpath` -- never `resolve()`, which touches the filesystem and follows symlinks -- with a final component filter so nothing can climb out regardless. Verified across traversal, single-file, unicode and repeated-separator inputs; reverting to the naive `relative_to` fails two tests.

Three blockers, two of them introduced or enabled by the campaign's own fixes. **The format safety token was self-issued.** `extras` on POST /tape-ops/execute is bound straight from the request body, and `{"confirmed_format": true}` -- a bare boolean -- was the entire gate. `_format` then minted its own SafetyToken to satisfy the confirmation it was supposed to be checking. AGENTS.md: "Never perform format or erase operations without positive barcode confirmation and a cryptographically valid safety token." The hole predates this branch, but the load-before-format fix is what made it lethal: previously the bypass died at "not loaded in a drive" before reaching mkltfs. A change that turns a latent auth hole into a working one has to close it in the same series. `_format` now refuses without a supplied FormatConfirmation and validates it against the requested barcode. POST /ltfs/format routes through FormatService.confirm, which checks the persisted one-time dry-run token -- a deliberate contract tightening: the route ignored the `safetyToken` its own callers already send (tests/i3/test_07_ltfs.py:53) and formatted on `confirm: true` alone. tests/i3/ needs a live emulator and was not run; expect test_format_with_timing to need a real token. **statvfs could read the host filesystem.** The capacity fix trusted a `mounted` flag that is the caller's belief. With OPENBLADE_HARDWARE_DRY_RUN=true and BackendMode.REAL -- a supported, tested config -- nothing is ever mounted, and the reviewer measured `capacity_bytes: 1965172678656` off the host disk, which jobs/archive.py then persists onto the cartridge row. `_is_distinct_mount()` compares st_dev with the parent's and fails closed. Verified against real LTFS: True while mounted, False after unmount. **`openblade mock inventory|load|unload` drove the real library.** Only `mock init` was pinned to BackendMode.MOCK; the rest used the env-driven config, so in the campaign's own shell `mock load` issued a real `mtx load`. Also: two of the format regression tests were vacuous against a *full* revert (with no load, "not in a drive afterwards" passes trivially) -- they now assert the load happened and that the cartridge returns to its original slot, and all three fail on a full revert; the CLI test fixture cleared only two env vars while the campaign shell exports six; a capacity assertion raced the host filesystem and is now a range; /ltfs/mount and /ltfs/unmount returned str(exc) from a bare except on an unauthenticated route; and one .pyc committed in bffd191 is restored. Remaining review findings -- raw exception text in the unauthenticated `jobs.error`, the 1-byte capacity threshold, unhydrated tape capacity after a restart, the missing can_unload_drive guard on RealLibraryBackend -- are recorded in the runbook rather than changed. The first of those should be fixed before merge. Gates: 1,331 passed, 2 failed (both reproduce on clean master). ruff 11 findings, all pre-existing; this branch removes 3 of master's 14.

ReadOnlyProxy stays as the read-only specialisation so "cannot write" is still stated by the annotation. Two hardenings found by attacking the boundary rather than by a failing test: - Callables leaving a proxy are wrapped in SealedCall. A bound method advertises its receiver, so `proxy.list_volume_groups.__self__.create_volume_group` was a live write straight through the allowlist. Sealed callables answer `()` and refuse every attribute. - `AllowlistProxy.__init__(proxy, evil, ...)` — the unbound form, which bypasses instance attribute lookup entirely — is refused: state binds exactly once.

Both mirror an endpoint the REST API already serves and call the two repository methods it calls; no service capability is invented. There is deliberately no removal operation, because the catalog layer has none. setup_facade.py is the entire write surface: a SetupFacade over the catalog (never the LibraryBackend) exposing five named operations, with every other attribute refused. Operation names are deliberately not the repository's, so a test can assert that this is the only module in the package naming a catalog write method. Ambiguity refuses even when confirmed: each operation has a plan_* twin that validates before the operator is asked, and the executing operation re-validates inside the write path. An unknown barcode, a tape already in another pool, or a name already taken returns typed candidates and changes nothing — notably, the underlying add_cartridge would otherwise CREATE a row for an unknown barcode and invent a tape that does not physically exist. setup_tools.py holds two guards over what may ever be tier 1: a fail-closed SETUP_TOOL_NAMES allowlist, and a DESTRUCTIVE_VERBS denylist that wins over it, so widening tier 1 to something destructive takes two deliberate edits, not one. The denylist is a substring test and therefore rejects `remove_*` via `move` — noted in the module docstring, since a future removal must be named `detach_*`. Every executed or declined action logs one structured JSON-encoded line, so a crafted name cannot forge a second one. The catalog has no events table the API uses for volume-group changes, so the log is the audit trail; no schema invented. --- openblade/assistant/setup_facade.py | 326 +++++++++++++++++++++++++ openblade/assistant/setup_tools.py | 356 ++++++++++++++++++++++++++++ 2 files changed, 682 insertions(+) create mode 100644 openblade/assistant/setup_facade.py create mode 100644 openblade/assistant/setup_tools.py diff --git a/openblade/assistant/setup_facade.py b/openblade/assistant/setup_facade.py new file mode 100644 index 0000000..8310e49 --- /dev/null +++ b/openblade/assistant/setup_facade.py @@ -0,0 +1,326 @@ +"""The narrow write facade — the assistant's *only* route to a catalog write. + +The assistant is read-only everywhere except here.

The session validates it against live state, builds a PendingAction whose preview names the objects ("Create volume group 'photos'"), and asks the confirm callback. Only an explicit yes executes. - No confirm callback => no facade, no setup registry, and the setup schemas are never shown to the model. One-shot mode therefore cannot execute anything, and its system prompt says setup execution needs the REPL. A half-wired session fails closed to read-only rather than to unconfirmed writes. - A decline is fed back as a result, not an error, so the model can adapt; the same action proposed again is answered from the decline cache without asking the operator a second time. - Ctrl-C/Ctrl-D at the prompt is a no. An unexpected failure during execution is curated, never echoed raw — a DSN can appear in a database error. The read-only prompt is unchanged byte-for-byte apart from an appended note about where setup execution lives; the setup prompt replaces only the hard-limits section and shares the destructive-flow and refusal text verbatim, because tier 1 softens no gate. --- openblade/assistant/__init__.py | 20 ++++ openblade/assistant/prompts.py | 81 ++++++++++++- openblade/assistant/session.py | 194 ++++++++++++++++++++++++++++++-- 3 files changed, 281 insertions(+), 14 deletions(-) diff --git a/openblade/assistant/__init__.py b/openblade/assistant/__init__.py index e85688f..340dd03 100644 --- a/openblade/assistant/__init__.py +++ b/openblade/assistant/__init__.py @@ -34,6 +34,13 @@ ) from openblade.assistant.provider import ChatReply, OllamaClient, ToolCall from openblade.assistant.session import AssistantSession, AssistantTurn +from openblade.assistant.setup_facade import setup_facade +from openblade.assistant.setup_tools import ( + SETUP_TOOL_NAMES, + ConfirmCallback, + PendingAction, + build_setup_registry, +) from openblade.assistant.tools import ( READ_ONLY_TOOL_NAMES, ReadOnlyTool, @@ -49,6 +56,7 @@ __all__ = [ "DISABLED_MESSAGE", "READ_ONLY_TOOL_NAMES", + "SETUP_TOOL_NAMES", "AssistantConfig", "AssistantDisabledError", "AssistantError", @@ -58,6 +66,7 @@ "AssistantUpstreamError", "ChatReply", "OllamaClient", + "PendingAction", "ReadOnlyTool", "ReadOnlyViolationError", "ToolCall", @@ -77,11 +86,17 @@ def create_session( *, config: AssistantConfig | None = None, http_client: httpx.Client | None = None, + confirm: ConfirmCallback | None = None, ) -> AssistantSession: """Build a session over a live :class:`~openblade.bootstrap.AppContext`.

11 Sep 2026 20:58:49 +0000 Subject: [PATCH 059/110] docs(assistant): document the two tiers and a worked pool-setup transcript MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the tier table, what tier 1 refuses even after a yes, the full guard table (allowlist, denylist, facade, confirmation gate, one-write-path AST scan), and a REPL transcript of setting up a pool end to end — including the moment the work turns destructive and it goes back to proposing, and what a declined action looks like.

A failure inside `plan` — which reads the live catalog — escaped the loop entirely. Not an AssistantError, so the transcript was not rewound and the REPL died with a traceback carrying the DSN from a SQLAlchemy connect error. Plan and confirm now get the curated treatment `perform` already had (type name only), and the REPL survives an unexpected defect in one question. 2. The repository commits per cartridge, so "add three tapes" is three transactions. A mid-loop failure left tape one committed while the model, the operator and the audit log were all told nothing happened. It now raises a typed SetupPartialWriteError carrying exactly which barcodes landed; the result says `partially_applied` and the audit line names them. Also from the review: - AssistantError is re-raised on the write path instead of being swallowed into a polite "could not be completed" — a facade violation is the loudest signal this design has, and it was being handed to the model as data. - A confirmed write that lands before the turn fails is no longer erased by the transcript rewind, and the CLI prints it on the error path too. Otherwise the assistant re-proposes an action the operator already approved and it already did. - DESTRUCTIVE_VERBS grew from 11 to 26. The original list let `purge_volume_group`, `destroy_pool`, `export_tape_to_mailslot` and `revoke_api_token` through, which made the "two independent guards" claim false — only the allowlist was stopping them. - The AST scan's write-method set is derived from CatalogRepository instead of hand-listed; the hand-written ten covered a fifth of the real write surface and would have rotted silently. - A broken confirmation prompt is a no. Fail closed: if we cannot establish that the operator agreed, they did not. - SealedCall gets the bind-once guard AllowlistProxy already documents. - Two tests the reviewer called vacuous now assert the thing their names claim. - `readonly.py` states the residual honestly: an allowlisted read returns a live ORM row, and a row knows its session, so the guarantee is "no attribute path to a write", not "no reachable write in the process". Pre-existing; the AST scans are what cover the deliberate version. Documented in the guide's limits too. Nits: a volume group named "0" is no longer read as a missing name; the create TOCTOU window is documented where it is accepted. All 14 structural guards re-mutation-checked after these changes — including the new ones, one of which came back VACUOUS on the first run (the test tripped during plan, leaving the write path's re-raise uncovered) and was fixed. --- docs/wiki/guides/assistant.md | 10 +- docs/wiki/reference/cli.md | 2 +- openblade/assistant/errors.py | 15 ++ openblade/assistant/readonly.py | 17 ++ openblade/assistant/session.py | 102 +++++++- openblade/assistant/setup_facade.py | 49 +++- openblade/assistant/setup_tools.py | 46 +++- openblade/cli/assist.py | 32 ++- tests/safety/test_assistant_read_only.py | 89 ++++--- tests/unit/test_assistant.py | 282 ++++++++++++++++++++++- 10 files changed, 574 insertions(+), 70 deletions(-) diff --git a/docs/wiki/guides/assistant.md b/docs/wiki/guides/assistant.md index 4ff0f3f..ca6b02b 100644 --- a/docs/wiki/guides/assistant.md +++ b/docs/wiki/guides/assistant.md @@ -51,7 +51,7 @@ built: | Read-only tool allowlist | `openblade/assistant/tools.py` (`READ_ONLY_TOOL_NAMES`) | A read tool registered without being added to the allowlist raises at startup.

The assistant is a new caller, not a new path. Every operation goes through the service the REST API and CLI already use -- execute_tape_request for robotics, FormatService.dry_run/confirm for format, ArchiveService/RestoreService for bulk data -- so job-queue drive ownership, RealHardwareGuard, the mount-state gate and the one-time SafetyToken all still apply because they live inside those services. No service capability is invented: there is no eject, import/export or delete. Structure: * MediaFacade is a third AllowlistProxy with its own resolver -- no instance state, thirteen named operations, every returned callable sealed. Its own validation reads go through the tier-1 read-only proxy, so the half of the module that decides cannot write. It never names a library/LTFS method directly, so SAFETY_003 stays intact without adding the assistant to ALLOWED_FILES. * MEDIA_TOOL_NAMES is a separate fail-closed allowlist, and the registry also refuses any name claimed by the tier-1 or read-only registries. The tier-1 DESTRUCTIVE_VERBS denylist is untouched, which is what makes every tier-2 name permanently unregistrable as a tier-1 tool. * ConfirmationGrade is a property of the tool and its resolved plan, never of the model's arguments. Robotics and archive take y/N; format takes the typed barcode; restore takes the typed word OVERWRITE exactly when the filesystem says the destination exists. perform() re-verifies the authorization against the action before calling anything, so the strength of a confirmation does not depend on the REPL prompt being correct. * Format keeps both phases: planning runs the real dry run and mints the real persisted token, and the executing operation presents that token back to FormatService.confirm. No dry run means no token means the format fails. * Ambiguity refuses before any prompt and again inside the write path: unknown barcode (with ranked candidates), a barcode in two places, an occupied drive or slot, an unspecified unload target, a mounted drive, an import/export element. * Failures are curated at the raise site -- the orchestrator's per-op constant, a typed OpenBladeError message, or safe_job_error's class name only. Raw mtx and mkltfs output never reaches the model or the operator. log_action now takes an AuditableAction protocol so both tiers write one audit stream in one format.

This module is the other thing the assistant may execute: the six media and +robotics operations the operator has to confirm *strongly* first. + +* ``load_tape`` / ``unload_drive`` / ``move_tape`` — robotics. Nothing is written, + nothing is lost; they move a cartridge between a slot and a drive. +* ``archive_path`` — copies a local directory or file onto tape. Additive. +* ``restore_path`` — copies an archived file back to local disk. Additive *unless* + the destination file already exists, in which case it destroys it. +* ``format_tape`` — irreversible. Everything on the cartridge is lost. + +Two things make this a new *caller* rather than a new *path*: + +1. Every operation goes through the service the REST API and the CLI already use — + :func:`openblade.nas.tape_orchestrator.execute_tape_request` for robotics, + ``FormatService.dry_run``/``confirm`` for format, ``ArchiveService.enqueue`` and + ``RestoreService.enqueue`` for bulk data. The job queue's drive and changer + ownership, ``RealHardwareGuard``, the mount-state gates and the one-time + ``SafetyToken`` all still apply, because they live *inside* those services and + this module does not reimplement any of them. No service capability is invented + here: there is no eject, no import/export, no delete, because the assistant has + no business owning one and the orchestrator's own export refusal stands. +2. :class:`MediaFacade` is an :class:`~openblade.assistant.readonly.AllowlistProxy` + with a custom resolver, exactly like the tier-1 facade. It holds no instance + state, an allowlisted name resolves to an operation *defined in this module*, + and every callable it hands out is a + :class:`~openblade.assistant.readonly.SealedCall`. ``facade._target``, + ``facade.__init__``, ``facade.library`` and ``operation.__closure__`` all raise. + +Reads go through the tier-1 read proxy. The facade validates against a +:class:`~openblade.assistant.readonly.ReadOnlyProxy` over the catalog and over +``InventoryService``, so its *validation* half cannot write even by accident, and +the live backends are reachable only as opaque arguments handed to the services +above. That is also why this module never calls a load/unload/move/inventory method +on a library backend or a format/mount method on an LTFS backend directly: +SAFETY_003 (:mod:`openblade.safety.import_guard`) forbids that outside the +authorized access points, and the assistant is deliberately not one of them. (The +forbidden call patterns are described here rather than written out, because the +guard is a line-based substring scan and spelling them would trip it — the same +reason :mod:`openblade.assistant.readonly` describes its one indirectly.) + +Ambiguity refuses even when confirmed. Every operation has a ``plan_*`` twin that +resolves the target against the live library before the operator is asked, and the +executing operation resolves it *again* inside the write path.

One-shot mode passes neither callback and is therefore offered neither tier's schemas. The media confirmation callback returns the operator's TEXT rather than a bool. A bool cannot express "typed the barcode", so the typed grade would collapse back into a y/N at the boundary; the registry decides whether the text satisfies the grade. Ctrl-C, EOF and a prompt that raises are all declines, never a yes. Archive and restore block the REPL for minutes, so a progress callback prints one line before and one after. The job id lands on the completion line because the services create the job inside the call that runs it -- there is no id to print beforehand, and a placeholder would be worse than the honest ordering. The REPL prints a destructive preview in red and demands the typed word; the banner and the one-shot note say so. The tier-2 prompt keeps the two-phase format flow and the bypass-refusal text verbatim from the tier-1 contract: tier 2 executes that flow instead of proposing it, and softens nothing.

The action-key and grade checks were each covered only by a scenario where a later check also refused, so removing them changed nothing. Both tests were rewritten to isolate their guard -- same-grade replay for the key check, a response that satisfies the real grade for the grade check -- and both mutations then killed them. A redundant guard covered by a redundant test is not a tested guard. The adversarial round also produced three tests from attacks rather than from design: mutating a frozen action's (mutable) arguments dict after authorizing it, passing a model-invented safety token as a tool argument, and bypassing __getattribute__ with object.__getattribute__. All three are refused; the last one is documented with the residual it does NOT claim.

example The guide's "two tiers" table becomes three, with the confirmation each one takes and why it is allowed. Adds the guard rows for the media allowlist, the media facade, the confirmation grade and the second AST scan; a section on what tier 2 refuses even when confirmed; and an explanation of why format still takes two phases when the assistant drives it. The worked example is captured verbatim from the mhvtl rehearsal rig with OPENBLADE_BACKEND=real and a real changer, real /dev/nst* drives, real mkltfs and real LTFS mounts: load OB0003L8 into drive 1 by ask-confirm-do, unload it by drive number, format scratch tape OB0007L8 through the typed-barcode flow (186 catalogued files, 203.4 MB named as lost before the prompt), archive a directory, restore it back. The restored file is byte-identical -- sha256 9597d98b...35dda0 both sides -- and the transcript includes the model's refused create_volume_group call, because a refusal that happens before any prompt is exactly the behaviour worth showing.

Nothing enforced that they still match the code, so they could describe a past release indefinitely. Adds a 'wiki' path filter (openblade/cli, openblade/api, the generator, and the generated pages themselves) and a wiki-reference job running `gen_wiki_reference.py --check`, wired into ci-gate. Blocking rather than advisory: the fix is one command, and a stale generated page reads exactly like a correct one.

LTFS is built from the pinned ref and cached on (ref, runner image), since it is compiled against the image's libicu/libfuse.

NOT MOVE with an I/E destination -- _dest_slot refuses import/export elements (defect 3.9) and must keep refusing; these carry their own guards instead. - _guard_export refuses an export that would take archived data out of the library, naming the cartridge, its volume group, the file count, the bytes and up to five catalog paths. extras["force"] is the single override. It fails CLOSED on a catalog-less repository: an unknown payload is not an empty one. The refusal re-raises (like OperationNotConfirmedError) rather than being flattened into a failed record -- and _safe_error_message lets its text through, because that text exists precisely to be read. - catalog/export_policy.py answers "what is on it?" once, so the preview and the refusal cannot disagree. It counts sibling cartridges in the volume group too: a block_stripe file is split ACROSS tapes. - CatalogRepository.set_cartridge_state writes the `exported` flag every restore path already reads. Nothing outside a fixture ever set it, so physically removing media left the catalog claiming the data was online. - MailslotService owns slot-picking policy (first empty storage slot on import, first empty I/E on export) and NAMES the slot it chose. --- openblade/catalog/export_policy.py | 123 +++++++++++++++ openblade/catalog/repository.py | 17 ++ openblade/nas/mailslot.py | 245 +++++++++++++++++++++++++++++ openblade/nas/tape_orchestrator.py | 109 ++++++++++++- openblade/nas/types.py | 6 + 5 files changed, 497 insertions(+), 3 deletions(-) create mode 100644 openblade/catalog/export_policy.py create mode 100644 openblade/nas/mailslot.py diff --git a/openblade/catalog/export_policy.py b/openblade/catalog/export_policy.py new file mode 100644 index 0000000..fa5e9a9 --- /dev/null +++ b/openblade/catalog/export_policy.py @@ -0,0 +1,123 @@ +"""What is lost when a cartridge leaves the library. + +Exporting media is the one operation in this product that makes archived data +unreachable without deleting anything: the bytes are fine, they are just in +someone's hand.

The test hardcoded destination "1,1,11", which was an empty slot when it was written (8f3adb1) and is now occupied, so the move is correctly rejected with 409 SlotOccupiedError. The product is right; the test was stale. Derive the destination from the live simulator inventory so a future seed change cannot rot it again. Mutation-checked: forcing require_service_token to reject, and pinning the helper back to "1,1,11", each make this test fail; restoring greens it.

The test still asserted the placeholder formula and seeded file records with no bytes behind them, so every file stats as missing and files_verified is 0. The product change was intended; the test was stale. Archive real bytes to the simulated tapes first, then assert the read-back checksum. Also assert files_corrupt == 1, since docs/b.txt carries a preset checksum that cannot match its tape contents — a mismatch is exactly what verify must flag. Mutation-checked: making verify return the recorded checksum instead of the tape read-back, and dropping the mismatch branch, each make this test fail.

All three are fixed with a mutation-checked regression test. 1. BLOCKER -- restore's overwrite grade was sampled at plan time and never re-checked. The window is the operator's thinking time at the prompt, and the writer can be a cron job, another tool, or the assistant's own previous action. Repro: plan a restore to a path that does not exist (grade YES_NO), create the file, answer "y" -- the file was destroyed. The applier now carries the plan's verdict into the write path and the facade refuses with `destination_changed` if reality no longer matches. The docstring had claimed this check existed. 2. BLOCKER -- the assistant refused to UNLOAD a mounted drive but would FORMAT the cartridge in it. Formatting runs mkltfs against a drive and the orchestrator LOADS a slotted cartridge to do it, so the mount-state non-negotiable applies here with more force than it does to unload, and the guard was simply absent. `_resolve_format_target` now runs it, and the preview names the drive the cartridge will be loaded into -- a format is also a media move, and the operator was not being told. 3. `create_file_record` is an upsert, so archiving a path that is already catalogued replaced the record describing the copy already on tape -- behind a y/N whose preview said "existing data on them is not touched". Detected at plan time and refused; the message names the colliding paths and the supported way through. Known trade-off, documented: a format does not purge catalog rows, so re-archiving the same paths after one is refused too. Also from the same round: * The decline cache keyed on raw argument VALUES, so "vol001l9" and " VOL001L9 " were different actions and one refused format could be re-proposed four more times. Confirmation fatigue is the realistic attack on a type-the-barcode gate. Normalization moved into the normalizers, where the key is built. * The cache is now consulted BEFORE planning. Planning a format runs the real dry run, which persists a live safety token; a model re-proposing a refused format left one live authorization behind per attempt. * A failed archive is not "nothing happened" -- the job writes file by file, so a failure part-way leaves files on tape. Long-running failures are now flagged possiblyPartial, reported to the model and the operator, and kept by the transcript rewind. * Tier 2 now requires tier 1. The tier-2 prompt describes both tiers, so a media-only session advertised a tool it would then refuse. * ACTING_OPERATIONS/DESTRUCTIVE_OPERATIONS were dead constants presented as a review surface; a test now ties them to the registry and the grades. * Dropped two unreachable `job.error` keys and added the token-expiry recovery line to the format preview. Nine further mutations, each confirmed to kill a named test: restore: expect_overwrite re-check -> test_a_destination_that_appears_after_the_yes_is_refused restore: applier passes the verdict -> test_a_destination_that_appears_after_the_yes_is_refused format: mount-state gate -> test_formatting_a_mounted_cartridge_is_refused archive: catalog-collision refusal -> test_archiving_over_a_catalogued_path_is_refused normalize: canonical barcode -> test_a_declined_format_is_not_re_proposed_under_another_spelling session: cache before planning -> test_a_repeated_format_proposal_mints_no_second_safety_token session: possibly-partial marker -> test_a_failed_long_running_action_is_reported_as_possibly_partial session: tier 2 requires tier 1 -> test_media_without_setup_is_off_rather_than_half_advertised facade: declared surface vs registry -> test_the_declared_acting_surface_matches_the_registry The worked example was re-captured on the mhvtl rig after these changes -- format (OB0008L8), archive and restore all still round-trip byte-identical, and the quoted collision refusal is the live message.

What the contract actually gives us (verified against both halves): - GET /aml/drives publishes `serialNumber` per drive, and every drive-scoped path in the Rev H matrix is keyed by it (catalog rows 106, 124-148). - GET /aml/physicalLibrary/elements publishes drive ELEMENT ADDRESSES with no serial (`ElementResource`). Both halves exist; the join between them does not, and the endpoint catalog documents no response fields at all. Joining the two lists by position is exactly the guess `hardware/correlation.py` exists to refuse. So: the mapping stays operator-declared via OPENBLADE_DRIVE_SERIAL_MAP, reusing `correlate_drives` (no second scorer), and refuses with a typed DriveCorrelationError naming what is missing — never positional order, which the SCSI backend tolerates but this transport must not. On top of the live sg_inq check it adds one check mtx cannot make: the declared serials are cross-checked against the serials this library reports, catching a map that belongs to a different library. A disjoint result warns rather than refuses (a library UI and a SCSI serial need not spell a drive the same way); a partial mismatch refuses, because overlap proves the forms are comparable. Correlation is built lazily on first use so a robotics-only deployment with no tape devices on the host starts exactly as before. - correlation.py: additive `verify_against_library_serials` only. - library.py: `build_drive_correlation` extracted so both real backends decide "which devices, probed through which nodes" in one place. - The refusal now reaches `validation._drive_device_or_blank`, which already catches DriveCorrelationError but not NotImplementedError. Tests: stubbed-session unit tests incl. two mutation checks (neutering the library cross-check and the positional guard each make the corresponding refusal test pass, proving neither is vacuous), plus integration tests against a uvicorn-launched emulator that assert the contract claim itself. --- openblade/bootstrap.py | 23 +- openblade/hardware/correlation.py | 72 ++++- openblade/hardware/library.py | 34 ++- .../hardware/scalar_http/library_backend.py | 169 ++++++++++- .../test_scalar_http_drive_device_emulator.py | 210 +++++++++++++ tests/unit/test_scalar_http_drive_device.py | 276 ++++++++++++++++++ 6 files changed, 763 insertions(+), 21 deletions(-) create mode 100644 tests/integration/test_scalar_http_drive_device_emulator.py create mode 100644 tests/unit/test_scalar_http_drive_device.py diff --git a/openblade/bootstrap.py b/openblade/bootstrap.py index 65d1394..629f2d2 100644 --- a/openblade/bootstrap.py +++ b/openblade/bootstrap.py @@ -15,6 +15,7 @@ from openblade.catalog.repository import CatalogRepository from openblade.config import BackendMode, OpenBladeConfig, load_config from openblade.domain.backends import LibraryBackend, LTFSBackend +from openblade.domain.policies import RealHardwareGuard from openblade.hardware.discovery import discover_library from openblade.hardware.library import RealLibraryBackend from openblade.hardware.ltfs import RealLTFSBackend @@ -374,11 +375,15 @@ class AppContext: restore_service: RestoreService -def _create_scalar_http_library(config: OpenBladeConfig) -> LibraryBackend: +def _create_scalar_http_library( + config: OpenBladeConfig, runner: SafeRunner, guard: RealHardwareGuard +) -> LibraryBackend: """Build the Web Services robotics backend for a real Scalar i3 AML endpoint.""" import httpx from openblade.domain.errors import RealHardwareDisabledError + from openblade.hardware.correlation import DriveCorrelation + from openblade.hardware.library import build_drive_correlation from openblade.hardware.scalar_http import ScalarHttpLibraryBackend, ScalarHttpSession if not config.scalar_url: @@ -391,7 +396,19 @@ def _create_scalar_http_library(config: OpenBladeConfig) -> LibraryBackend: session = ScalarHttpSession( client, username=config.scalar_user, password=config.scalar_password ) - return ScalarHttpLibraryBackend(session) + + def _correlate() -> DriveCorrelation: + # Deferred to first use: local SCSI discovery and sg_inq are only needed for + # the LTFS data path, so a robotics-only deployment (no tape devices on this + # host) keeps starting exactly as it did before drive_device was implemented. + return build_drive_correlation( + config=config, + runner=runner, + guard=guard, + discovery=discover_library(runner, guard), + ) + + return ScalarHttpLibraryBackend(session, correlation_factory=_correlate) def _create_real_backends(config: OpenBladeConfig) -> tuple[LibraryBackend, LTFSBackend]: @@ -399,7 +416,7 @@ def _create_real_backends(config: OpenBladeConfig) -> tuple[LibraryBackend, LTFS runner = SafeRunner(dry_run=config.hardware_dry_run) library: LibraryBackend if config.robotics_transport == "webservices": - library = _create_scalar_http_library(config) + library = _create_scalar_http_library(config, runner, guard) else: discovery = discover_library(runner, guard) library = RealLibraryBackend(config=config, runner=runner, discovery=discovery) diff --git a/openblade/hardware/correlation.py b/openblade/hardware/correlation.py index 9d687f9..91580b7 100644 --- a/openblade/hardware/correlation.py +++ b/openblade/hardware/correlation.py @@ -49,13 +49,20 @@ The serials are captured either way, so ``connect-i3`` output tells an operator exactly what to paste into ``OPENBLADE_DRIVE_SERIAL_MAP``. + +A backend that can *ask the library* which drives it has (the AML Web Services +backend can; ``mtx`` cannot) gets one more check on top of the two above: +:func:`verify_against_library_serials` compares the declared serials with the +serials the library reports, which catches a declaration that matches this +host's drives but belongs to a different library.

This exposes the same session loop over HTTP for a UI or an automation to use. Read-only is structural, not a policy note. create_session builds the tier-1 registry and the write facade only when it is handed a confirmation callback, and an HTTP request has nobody to ask — so the route passes none and the mutating tools are never constructed. `_require_read_only` then asserts that outcome (checking each part independently, not just `setup_enabled`) so a future change to the factory fails loudly here instead of silently exposing writes. The same reasoning covers the media tiers: confirmation is interactive. Request carries the whole conversation; only user/assistant roles are accepted, so a caller cannot replace the system prompt or forge a `tool` message claiming something was executed. Response is {reply, toolCalls: [names only]} — arguments and results can carry catalog contents. 503 with the CLI's curated setup message when OPENBLADE_OLLAMA_URL is unset; 502 for a provider or round-limit failure (already curated at the raise site). Declared `def`, not `async def`, so the blocking session loop runs in the threadpool rather than on the event loop. Rate limit: in-process token bucket per peer address, env-tunable, with idle eviction so the key set stays bounded. X-Forwarded-For is ignored on purpose — honouring caller-controlled identity defeats the limit. It is a cost bound, not access control: the native API has no auth on this base, and since /assist is a native route, the parallel bearer-auth work will cover it at integration with no change here. The docs say all of this plainly. Tests: stubbed-Ollama MockTransport happy path, disabled-503, upstream-502 with no leaked host, role/shape rejections, scalar-api-only 404, rate limit plus the bucket on a fake clock, and two mutation checks — adding a confirm callback makes the guard refuse, and neutering the guard as well lets a tier-1 tool really write, proving the read-only tests are not vacuous.

Semantics v1, deliberately small: - tree + stat come from catalog metadata; 0555/0444, no write bit anywhere - every mutating op returns EROFS (explicit handlers, not just the `ro` flag) - read of a file not in the staging cache returns EIO and logs the exact `openblade restore` command that fixes it - `--hydrate` (OFF by default) instead blocks the read while the restore service fetches from tape; the blocking-read tradeoff is documented - without the extra the CLI prints an install hint and exits 1 The operations object deliberately does not subclass `fuse.Operations` and imports nothing from fusepy, so the whole semantic layer is unit-testable with the extra absent. Verified with a real mount on this host (/dev/fuse): tree, stat, cached read, EIO, hydrate, EROFS, clean unmount.

From: Amantux Date: Fri, 11 Sep 2026 23:41:54 +0000 Subject: [PATCH 080/110] feat(hardware): TapeAlert parsing and `openblade hardware drive-health` New openblade/hardware/tapealert.py follows sg.py's shape: captured sample-output constants, a pure parser, and one guarded `read_tape_alerts` taking SafeRunner + RealHardwareGuard. - The 64-flag table (number, name, severity) is transcribed from T10/02-142r0 "TapeAlert Diagnostic Specification" v3.0, section Tape Drive Flag Definitions. v3.0 only classifies flags 1-54; SSC-3's later 55-60 are reported UNKNOWN rather than given a guessed severity. - Names are matched against sg3_utils' own spellings (captured from the rig) as well as the spec names -- they differ often enough (spec "Clean Now" vs sg_logs "Cleaning required") that spec-only matching would drop flags. - A drive with no TapeAlert page is not an error: supported=False + a reason, and the CLI prints "not supported by this drive" and exits 0. A failed sg_logs invocation is distinguished from an absent page. Format verified empirically, not from memory: `sg_logs -p 0x2e` on the rig's mhvtl ULT3580-TD8 (page present, all flags 0 -- mhvtl serves the page but never sets a flag), on the changer (undecodable payload, rc=0), and for an unimplemented page (illegal request, rc=5). The set-flag fixtures were made by hand-encoding page 0x2E and decoding it with sg_logs itself (`--in=`), so the fixture text is the real tool's formatting. Guard enforcement is mutation-checked: removing `guard.validate()` fails test_read_tape_alerts_requires_the_guard.

Replaced that with what `openblade fuse mount` actually does -- semantics table, the --hydrate blocking-read tradeoff and why it defaults off, whole-file buffering, and the fact that it serves the catalog namespace and not the NAS one. The remaining gaps (SMB, NFS, SFTP, the three hydration implementations) are unchanged. Added stale-doc pointers for the pages this work invalidates but that are out of scope here: docs/wiki/README.md, docs/fuse.md, docs/runbooks/real-data-campaign.md and the readiness roadmap.

The group may already be in SQLAlchemy's identity map with a collection loaded before the newest cartridge was linked, so a STALE "no siblings" answer reads as "safe to export". Query the cartridges directly instead. - MailslotService now add_cartridge()s before set_cartridge_state().

Add an opt-in bearer token. OPENBLADE_API_TOKEN (or OPENBLADE_API_TOKEN_FILE, which wins when both are set) turns it on; unset means auth is disabled and behaviour is unchanged, announced with a loud startup warning so the default cannot be silent. A token file with mode looser than 0600 warns; a missing/unreadable/empty one is fatal, because failing open there gives an operator who asked for auth no auth at all. Enforcement is ONE chokepoint -- an http middleware, not per-route dependencies -- so a route added later is protected by default and a missed decorator cannot become a shipped hole. It is registered before enforce_scalar_api_scope so emulator-only mode still answers 404 rather than 401 for native paths. Scope is native routes only. /aml/* and /iblade/* keep their own AML session auth untouched (it is the i3 wire contract), and /health, /healthz and /readyz stay open for monitors. Comparison is secrets.compare_digest over bytes; the 401 body is curated and never echoes the supplied token; failure logs scrub CR/LF from client-controlled values. --- openblade/api/api_auth.py | 312 ++++++++++++++++++++++++++++++++++++++ openblade/api/main.py | 15 ++ 2 files changed, 327 insertions(+) create mode 100644 openblade/api/api_auth.py diff --git a/openblade/api/api_auth.py b/openblade/api/api_auth.py new file mode 100644 index 0000000..9732b89 --- /dev/null +++ b/openblade/api/api_auth.py @@ -0,0 +1,312 @@ +"""Bearer-token authentication for the OpenBlade-native REST surface. + +Scope is deliberately narrow.

Two mutation checks, because a coverage sweep is the easiest test to write vacuously: - test_sweep_catches_an_exempted_router simulates a router left out of the chokepoint and asserts the sweep goes red. - test_the_sweep_does_not_take_its_route_list_from_the_code_it_tests pins that the expected-gated list is computed independently of api_auth.requires_api_token. The first draft derived it from that function and was genuinely vacuous: exempting /archive deleted those routes from the sweep instead of failing it, and the suite stayed green. Verified by running that mutation before and after the rewrite. Also covers: token-file precedence and permission warnings, fail-closed on a missing/empty file, the AML surface being unaffected in both modes, /health open in both modes, docs/openapi open when disabled and gated when enabled, the 401 never echoing the supplied token, CRLF scrubbing in the failure log, and that secrets.compare_digest is what does the comparison. --- tests/integration/test_api_auth_sweep.py | 362 +++++++++++++++++++++++ tests/unit/test_api_auth.py | 281 ++++++++++++++++++ 2 files changed, 643 insertions(+) create mode 100644 tests/integration/test_api_auth_sweep.py create mode 100644 tests/unit/test_api_auth.py diff --git a/tests/integration/test_api_auth_sweep.py b/tests/integration/test_api_auth_sweep.py new file mode 100644 index 0000000..0413017 --- /dev/null +++ b/tests/integration/test_api_auth_sweep.py @@ -0,0 +1,362 @@ +"""Coverage sweep for the native REST bearer-token layer. + +The point of this module is that nobody has to remember anything.

through one client and hits native routes (/jobs, /ltfs/*, /archive/*, /api/libraries) as well as /aml/*, so with a token configured the suite needs to authenticate to both. A request event hook attaches the token to native paths only, leaving the AML surface's Authorization header alone. A few native routes (/api/libraries, /status/*) want both credentials at once, so the AML session is moved to the sessionID cookie -- the channel require_auth prefers anyway -- while Authorization carries the API token.

The native API token neither unlocks nor blocks +them. If you need that surface locked down, that is a separate change to the AML +session layer — do not assume this token covers it. + +**Authorisation.** There is one token and it is all-or-nothing. There are no +scopes, no read-only tokens, no per-user attribution. Anyone holding the token +can format a tape. + +**Transport.** The token travels in a plain header. Terminate TLS in front of +OpenBlade, or keep the port on a trusted network. A bearer token on plaintext +HTTP is a token you have published. + +**Rotation.** Changing the token means editing the env var or file and +restarting. There is no online rotation and no grace period for the old value. + +**The safety gates.** Authentication is orthogonal to +[the safety model](safety-model.md). An authenticated caller still has to do the +dry-run → token → confirm dance to format a tape. + +--- + +## Rolling it out without an outage + +Every client of the native API needs the header before you flip the switch. +In a default deployment that is at least: + +1. **The React frontend**, if it talks to the API from a browser. It has no + place to put a bearer token that a browser user cannot also read — if you + serve the UI publicly, front it with a reverse proxy that injects the header + and authenticates users itself, rather than shipping the token to the client. +2. **Your own scripts and cron jobs.** +3. **Monitoring**, unless it only polls `/health`. + +A safe sequence: + +```bash +# 1. Pick the token, but do not enable it yet. +python3 -c "import secrets; print(secrets.token_hex(24))" | tee /etc/openblade/api-token +chmod 600 /etc/openblade/api-token + +# 2.

Sending the header while auth is still off is a +no-op, which is exactly why it is the right order: you find the client you forgot +*before* it starts failing. + +--- + +## A wrinkle worth knowing: two credentials, one header + +A few native routes — `/api/libraries`, `/status/library`, `/status/catalog`, +`/system/config-summary` — additionally require an **AML session**, because they +read library state through the emulator layer. With native auth enabled, the +`Authorization` header is taken by the API token, so those routes need the AML +session delivered the other way: as the `sessionID` cookie that +`POST /aml/users/login` sets. + +```bash +# Log in for the AML session cookie, then send both credentials. +curl -c /tmp/ob-cookies -X POST http://localhost:8000/aml/users/login \ + -H 'Content-Type: application/json' \ + -d '{"name":"admin","password":"password"}' + +curl -b /tmp/ob-cookies -H "Authorization: Bearer $OPENBLADE_TOKEN" \ + http://localhost:8000/api/libraries +``` + +`require_auth` prefers the cookie and only falls back to the bearer token, so +this works in both modes and is what the i3 compliance suite does. + +--- + +## Troubleshooting + +**Everything returns 401, including with the token.** Check the server actually +loaded the token you think it did — a `OPENBLADE_API_TOKEN_FILE` with a stray +trailing space in the *path*, or a file the service user cannot read, fails +startup rather than falling back.

The campaign's own diagnosis was LTFS index overhead, which does not stop mattering at one byte: a tape with a sliver left still ENOSPCs on an empty file. Recorded in docs/runbooks/real-data-campaign.md under "Reported rather than changed". A tape is now full when its free space is at or below a reserve of min(64 MiB, 1% of capacity) -- ceiling sized for a full-cartridge LTFS index plus block-size rounding (0.001% of an LTO-8), fraction so the policy stays usable on the rig's 95 MiB cartridges. The derivation, and what the mhvtl rig could and could not be made to demonstrate, are in the module docstring. The policy lives in one place, openblade/domain/capacity.py, and both write paths go through it: `jobs/archive.py::_has_room_for` (which also stops re-deriving `capacity - used` itself), and `jobs/sharded_archive.py`, which had no capacity check at all -- a full lane there was a raw OSError [Errno 28] from inside a batch. It is now a TapeFullError naming the tape. This does NOT add spillover to the sharded path; that gap stays as the runbook records it. `test_a_tape_with_exactly_enough_room_is_still_chosen` moves its boundary by the reserve: "exactly enough room" now means above the reserve, by design.

It does not + account for the index that will be written when we unmount. +* Free space does not arrive one byte at a time. ``used_bytes`` for a tape this + process has not mounted comes from the catalog and is byte-granular, so a + free figure of "512 bytes" is entirely representable there and is exactly the + state nothing can be written into. + +Measured on the mhvtl rig (2026-09-11, one 8000 MB cartridge formatted, filled +with incompressible data until ``write`` returned ENOSPC): + +* capacity 6,569,328,640 bytes, ``f_frsize`` 524,288 -- LTFS reports free space + in 512 KiB blocks, so on that path ``f_bavail`` steps 524,288 -> 0 and the + sub-block tail of the medium is never visible as free space at all. +* at ``free == 0``, creating a **zero-byte file** fails with ``ENOSPC`` -- + the campaign's failure, reproduced directly. +* unmounting that 100%-full tape succeeded, so on this rig the drive's own + end-of-medium margin absorbed the final index write. + +In other words the rig can demonstrate the zero-free half of the problem but +not the nonzero-free half, because its free-space reporting cannot express it. +The reserve is therefore sized conservatively rather than fitted to a measured +failure point: it costs 0.001% of a real LTO-8 cartridge, and the failure it +prevents cost the campaign an aborted 1,073-file archive job. + +So the reserve is **the smaller of 64 MiB and 1% of the medium's capacity**: + +* 64 MiB is the ceiling, and comfortably covers a full-cartridge index plus + block-size rounding on real LTO media. Against LTO-8's ~6.6 TiB usable that is + 0.001% of the tape -- unmeasurable waste in exchange for never ENOSPCing. +* The 1% floor keeps the policy usable on *small* media, which is not a + hypothetical: the campaign's mhvtl rig deliberately runs 400 MB cartridges + presenting **99,614,720 bytes (95 MiB)** of usable LTFS capacity in order to + force spillover (runbook §1). A flat 64 MiB reserve would write off two thirds + of such a tape. 1% of 95 MiB is ~1 MiB, which is still ~2000x the 512 bytes + that provably ENOSPCs, and scales with the file count the medium can hold. + +The reserve is deliberately a constant policy and not a config knob: an operator +tuning it down to 0 reintroduces the exact campaign failure. +""" + +from __future__ import annotations + +# Ceiling on the reserve.

So after every restart each tape reported the fictional 12 GB default until this process had mounted it once, and `_choose_tape` believed a nearly-full 6.57 GB cartridge still had 12 GB free. The campaign recorded this as "a tape this process has never mounted still assumes 12 GB" and left it. The catalog's `cartridges` rows are the authority -- `jobs/archive.py` writes `capacity_bytes`/`used_bytes` onto the row at the end of every tape's turn, from the statvfs numbers measured while it was mounted. `bootstrap` reads them once (`_catalog_tape_states`) and passes them to the constructor. Never fatal, in three ways: a missing/unreadable database is an empty mapping, a barcode with no row falls back to the configured default with a debug log, and a row with a non-positive capacity is ignored rather than trusted. `used` is clamped into the capacity so a stale row cannot make a tape look fuller than it is.

The warning said only "not cross-checked", which undersells the other possibility: the controller may be driving a different library than the drives attached to this host, and then a load puts a cartridge into an element whose drive is not here. Both the warning text and the two module docstrings now name that case and tell the operator how to settle it.

Section 4 is the honest half: per-file load/unload is unchanged because the tree restore reuses the existing per-file services rather than reimplementing them; sharded archive still catalogs under the absolute source path; `--lanes` often finds nothing on a fresh volume group; and docs/wiki/reference/cli.md is stale on this branch by design -- it is a generated artifact owned elsewhere. --- docs/runbooks/mailslot-and-bulk-restore.md | 242 +++++++++++++++++++++ 1 file changed, 242 insertions(+) create mode 100644 docs/runbooks/mailslot-and-bulk-restore.md diff --git a/docs/runbooks/mailslot-and-bulk-restore.md b/docs/runbooks/mailslot-and-bulk-restore.md new file mode 100644 index 0000000..bdc1dcf --- /dev/null +++ b/docs/runbooks/mailslot-and-bulk-restore.md @@ -0,0 +1,242 @@ +# Mailslot (I/E) flows and bulk restore — mhvtl rig addendum + +> Addendum to [`real-data-campaign.md`](real-data-campaign.md).

Design notes worth knowing + +**The refusal lives in the orchestrator, not the CLI.** `TapeOperationOrchestrator` +is this codebase's single choke point for moving media, so `IMPORT`/`EXPORT` +became op types there and the guard sits inside `_export`. Anything that reaches +the orchestrator is guarded, including `POST /tape-ops/execute`. It fails +**closed** on a catalog-less repository: an unknown payload is not an empty one. + +**`MOVE` still refuses I/E destinations.** Defect 3.9 (an unvalidated +`dest_slot_id` ejecting a cartridge holding 358 archived files) stays closed — +`_dest_slot` rejects import/export elements exactly as before. The new op types +are the only way to reach the mailslot, and they carry their own guard. There is +a regression test for this. + +**The guard is mutation-checked** (both halves), see the test commit message. + +**Export writes `cartridges.state = "exported"`.** That flag was read by +`jobs/restore.py`, `jobs/sharded_restore.py` and `jobs/archive.py` and set by +nothing outside a fixture, so media leaving the library used to leave the catalog +claiming the data was online. Import clears it. A unit test demonstrates the +whole consequence chain: export → `run_restore_job` raises `CartridgeOfflineError`. + +**A cartridge in the mailslot is still `CartridgeState.IN_SLOT`** at the library +layer — it is inside the machine until a human opens the door. Whether its *data* +is online is the catalog fact above. `find_slot_by_barcode` does not see it, so +nothing can load or unload to it by accident. + +--- + +## 4. Still true after this work (do not assume otherwise) + +- **Per-file load/unload remains.** `restore tree` reuses `run_sharded_restore` / + `run_restore_job` verbatim rather than reimplementing the loop, and those load + and unload around each file. Grouping the plan by cartridge keeps one tape's + files consecutive, which helps locality but does **not** remove the swap. The + campaign runbook's "1,073 restores produced ~1,073 load/unload pairs" still + describes the cost; fixing it means a batching restore session in the service + layer, which is a separate piece of work. +- **Sharded archive catalogs files under their absolute source path**, not under + `//…` the way `run_archive_job` does. So the prefix for a + `restore tree` of sharded content is the source directory + (`restore tree /data/photos`), not `/photos`. This is existing + `run_sharded_archive` behaviour, identical through the API; the CLI wraps it + rather than changing it. Worth unifying, deliberately, at some point. +- **`--lanes N` often finds nothing on a fresh volume group.** + `run_sharded_archive` links a lane cartridge to the volume group only when the + cartridge row does not already exist, so media the catalog already knows about + never joins the group. `--lane-barcode` (repeatable) is the reliable form and + the error message says so. Again: identical on the API path. +- **Restore-to-a-directory basename collapse** is unchanged in the *single-file* + paths. `restore tree` avoids it; `openblade restore --path … --to ` does + not. +- **`docs/wiki/reference/cli.md` is stale on this branch** and + `tests/unit/test_wiki_reference_generated.py` is red because of it. The page is + a build artifact of `tools/gen_wiki_reference.py`; regenerating it is owned + elsewhere and these commands will be picked up then. + +--- + +## 5. Simulator support + +`MockLibraryBackend` gained `num_import_export_slots` (default **0**, so nothing +that constructs it today changes) with elements numbered after the storage slots, +mirroring the i3. `openblade mock init --ie-slots` defaults to **4** — the rig +and i3 shape — so every mailslot flow above is exercisable with no hardware: + +```bash +openblade mock init --slots 8 --drives 2 --cartridges 3 --ie-slots 4 +openblade mailslot list +openblade mailslot export MCK00003 +openblade mailslot import 9 +``` + +`mock_state.json` round-trips the elements by their own numbers, and a state file +written before I/E slots existed still loads (as a library with no mailslot). From 8f738a4040d795f8b56fe0b4f595742627a90964 Mon Sep 17 00:00:00 2001 From: Amantux Date: Sat, 12 Sep 2026 02:15:12 +0000 Subject: [PATCH 094/110] fix(restore): refuse a catalog path that cannot map safely under --dest Found by the path-escape test added alongside it, which is the point of writing that test. `_relative_parts` strips `""`, `"/"`, `"."` and `".."` from the components it joins onto `--dest`, then fell back to `path.name` when nothing survived. For the catalog path `/vg/..` that basename is literally `".."`, so the fallback put the escape straight back and the destination became `/..`. Catalog rows are not trusted input here: `create_file_record` normalises with `PurePosixPath`, which does not collapse `..`. Now it raises the typed `UnsafeCatalogPathError` instead. The CLI already curates OpenBladeError through `safe_job_error`, so the operator gets the message and exit 1 rather than a surprise write outside the destination. The test asserts the real invariant -- never outside `--dest` -- accepting either a contained path or a typed refusal, with a separate test pinning that the traversal-only case is the refusal. --- openblade/domain/errors.py | 10 +++++++++ openblade/jobs/tree_restore.py | 19 ++++++++++++++-- tests/unit/test_tree_restore.py | 40 +++++++++++++++++++++++++++++++++ 3 files changed, 67 insertions(+), 2 deletions(-) diff --git a/openblade/domain/errors.py b/openblade/domain/errors.py index 2e0513e..65b4ed8 100644 --- a/openblade/domain/errors.py +++ b/openblade/domain/errors.py @@ -74,6 +74,16 @@ class CartridgeOfflineError(OpenBladeError): """Cartridge is exported/offline.""" +class UnsafeCatalogPathError(SafetyViolationError): + """A catalog path cannot be mapped under a restore destination safely. + + Catalog rows are not trusted to be well-formed: ``create_file_record`` + normalises with ``PurePosixPath``, which does not collapse ``..``.

Reproduced end to end. The source slot is now resolved FROM THE BARCODE; `slot_id` is only ever a cross-check, and a disagreement is refused. Import refuses likewise when the element does not hold the barcode the request names. 2. **`ie_slot` reached `mtx transfer` unvalidated.** `_dest_slot` refuses an unvalidated MOVE destination with a comment explaining exactly this incident; the new op types skipped it. `ie_slot` is now checked against the library's own `import_export_slots()` and the destination storage slot against `inventory().slots`, both for occupancy too. Typed as `ImportExportSlotError` so the specific, device-path-free reason survives the error curation instead of becoming "Tape export operation failed". 3. **The catalog `exported` flag was written only by MailslotService**, so an export through `/tape-ops/execute` moved the media and left every restore path believing the data was online -- the exact failure the service's own comment warns about. Moved beside the move, in the orchestrator, where the repo is already in hand. Also: IMPORT/EXPORT now take the barcode lock (a concurrent restore could load the tape between resolve and move), and `assess_export` no longer refuses a cartridge that carries nothing just because a SIBLING in its volume group does. That reasoning was wrong -- a shard is a file instance, so a tape holding part of a striped file is caught by the real check -- and it refused routine scratch-tape rotation with the false sentence "still carries archived data". A guard that cries wolf is a guard that gets `--force`d. Sibling data is still reported, as context. In exchange the guard now also refuses while a `pending` write is in flight to the tape. Tree restore: catalogued records with nothing archived are reported as `skipped` instead of silently dropped from a run that says "completed"; an interior `..` is refused rather than stripped (stripping made `/vg/a/../x.txt` and `/vg/x.txt` collide); and a sharded-restore error keeps its curated text instead of being flattened to "Job failed (RuntimeError)". CLI: `restore file --dest` treats a non-existent path as a file unless `--into-dir` is passed (`is_dir()` is false for a directory that does not exist yet, so `--dest /tmp/outdir` wrote a *file* named `outdir`); the catalog lookup moved ahead of the job row so a typo leaves no orphan job; skipped files are called out on stderr; and a library with no mailslot now says so instead of claiming the mailslot is full. Tests: 11 new, attacking the orchestrator directly rather than the service, since that is the surface `/tape-ops/execute` exposes. Mutation-checked (each restored byte-for-byte): re-trust `request.slot_id` -> 1 fails; drop the `ie_slot` validation -> 1 fails; drop the catalog state write -> 4 fail. `test_a_library_with_no_mailslot_refuses_by_type` was passing for the wrong reason (it asserted only the exception class, which the "all slots occupied" branch also satisfies) and now asserts the message. --- openblade/catalog/export_policy.py | 61 +++-- openblade/cli/main.py | 39 +++- .../domain/__pycache__/errors.cpython-310.pyc | Bin 3704 -> 6293 bytes openblade/jobs/tree_restore.py | 56 ++++- openblade/nas/mailslot.py | 36 ++- openblade/nas/tape_orchestrator.py | 130 +++++++++-- tests/unit/test_cli_new_commands.py | 36 ++- tests/unit/test_mailslot_service.py | 215 +++++++++++++++++- tests/unit/test_tree_restore.py | 35 ++- 9 files changed, 525 insertions(+), 83 deletions(-) diff --git a/openblade/catalog/export_policy.py b/openblade/catalog/export_policy.py index 4dcfe6b..7344d35 100644 --- a/openblade/catalog/export_policy.py +++ b/openblade/catalog/export_policy.py @@ -21,6 +21,13 @@ {FileInstanceState.ARCHIVED.value, FileInstanceState.VERIFIED.value} ) +# A `pending` instance is a write in flight: the archive job has claimed a tape +# path on this cartridge and has not finished.

But `OPENBLADE_DRIVE_SERIAL_MAP` is documented in `correlation.py` as *mtx* Data Transfer Element numbering, 0-based, and the i3 web UI numbers drive bays from 1. Nothing reconciled the two number spaces. A map that is merely shifted passed the sg_inq check AND the library serial cross-check — both report success — and then handed back a neighbouring drive's device. Silent LTFS write to the wrong cartridge, which is exactly the failure `_UNVERIFIED_CORRELATION` refuses positional order to avoid. Fixed by `_refuse_on_element_address_mismatch`: the declared element ids must EQUAL this library's drive element addresses, checked against a live `inventory()` before the correlation is cached. Equality both ways — a declared element the library lacks means the wrong number space; a library element the map omits would have a cartridge loaded into it with no device to mount it, which `correlate_drives` already refuses for the SCSI backend. The emulator test that should have caught it was a tautology: it invented the element ids with `enumerate()` and asserted against the same range, never reading a real element address. It now derives them from `inventory()`, and there are new refusal tests plus a mutation check proving the guard is what stops the wrong-drive result. Also from the review: - `library_drive_serials` caught only `ScalarHttpError`, so a connect/timeout/TLS failure escaped as a raw httpx error — breaking its "None means unreadable" contract and putting upstream text (which for OPENBLADE_SCALAR_URL can embed credentials) into a traceback. Now caught; the log records the exception TYPE, not its text. - The refusal message told operators to read element ids off `connect-i3`, an mtx command that cannot run on this transport. It now names the AML elements endpoint, which is the actual source of truth. - `build_drive_correlation`'s docstring claimed the AML backend passes `element_count`; it does not and cannot. Says so, and points at the stronger check that replaces it. /assist, same review: - It was the app's only sync route handler, so it borrowed from AnyIO's shared 40-token default threadpool and held a token for up to max_rounds x timeout (12 min). A few requests could starve every sync dependency in the process — including the AML emulator surface. Now `async def` with an explicit hand-off under its own small capacity limiter, and a bounded queue wait that sheds load with a curated 503 before calling the model. - Each turn now gets its own DB session. `AppContext.catalog` wraps one process-global SQLAlchemy Session; the assistant reads it from a worker thread and calls `expire_all()` between rounds, which could expire rows out from under a request on the loop thread. `inventory_service` holds no session, so it stays shared. - A failed read-only guard leaked an httpx.Client per request. --- docs/wiki/guides/assist-api.md | 15 +- openblade/api/routes_assist.py | 131 ++++++++++++++---- openblade/hardware/library.py | 12 +- .../hardware/scalar_http/library_backend.py | 70 +++++++++- tests/integration/test_assist_api.py | 81 +++++++++++ .../test_scalar_http_drive_device_emulator.py | 63 +++++++-- tests/unit/test_scalar_http_drive_device.py | 117 +++++++++++++++- 7 files changed, 442 insertions(+), 47 deletions(-) diff --git a/docs/wiki/guides/assist-api.md b/docs/wiki/guides/assist-api.md index 70f3cdd..c619186 100644 --- a/docs/wiki/guides/assist-api.md +++ b/docs/wiki/guides/assist-api.md @@ -102,12 +102,25 @@ Set OPENBLADE_OLLAMA_URL to an Ollama endpoint to enable it: The route reads the same environment as the CLI (`OPENBLADE_OLLAMA_URL`, `OPENBLADE_OLLAMA_MODEL`, `OPENBLADE_OLLAMA_API_KEY`, `OPENBLADE_OLLAMA_TIMEOUT`, -`OPENBLADE_ASSISTANT_MAX_ROUNDS`) plus two of its own: +`OPENBLADE_ASSISTANT_MAX_ROUNDS`) plus four of its own: | Variable | Default | Meaning | |---|---|---| | `OPENBLADE_ASSIST_RATE_BURST` | `5` | Requests allowed back-to-back per client | | `OPENBLADE_ASSIST_RATE_WINDOW_SECONDS` | `60` | Window those refill over | +| `OPENBLADE_ASSIST_MAX_CONCURRENCY` | `2` | Assistant turns running at once, process-wide | +| `OPENBLADE_ASSIST_QUEUE_TIMEOUT_SECONDS` | `30` | How long a request waits for a slot before `503` | + +### Why concurrency is capped so low + +A turn is a long blocking call — up to `max_rounds × timeout`, 12 minutes on the +defaults.

BYPASS: /aml/proxy/libraries/{id}/probe was exempt. It is mounted under /aml but is NOT emulator wire contract (not a matrix endpoint; it 404s in scalar_api_only mode) -- it is an OpenBlade-native route that opens an outbound connection to an operator-supplied host:port and relays a username/password. The only thing in front of it was the AML session, whose shipped default credential is admin/password. Proven reachable with no API token; now 401 without one, 200 with. The prefix is a mount point, not a statement of ownership, so classification gets an explicit native-exception list rather than a bare string prefix. 2. VACUOUS SWEEP: 64 of 190 swept operations carry their own Depends(require_auth) and already answered 401 with this layer removed, so asserting status alone tested nothing for a third of the surface. The sweep now asserts the native 401 BODY, which is distinguishable from the AML layer's. Deleting the middleware went from 134 failures to 201. Also fixed from the same review: - Classify on the path the router matches (scope path minus root_path), not a prefix re-derived from X-Forwarded-Prefix. Under `uvicorn --root-path /ob` the old code gated /ob/health and /ob/aml/... -- fail-closed, but it broke the health exemption and the AML contract in a supported deployment. - The 401 now carries nosniff/X-Frame-Options/Referrer-Policy. add_security_ headers is registered earlier and so never saw a short-circuited rejection, making the 401 the only response in the app without them. - Tests for the two invariants that were comments: middleware registration order (scope enforcement must stay outermost so emulator-only mode 404s), and that no gated path has an exempt-looking tail, which is what makes trusting X-Forwarded-Prefix safe. - i3 conftest uses the cached token accessor instead of re-reading the file per request, and now raises a named error instead of silently destroying a Basic-auth AML credential it cannot carry. - Docs: /aml/proxy row added; corrected a false claim that a trailing space in the token-file path fails startup (it is stripped); documented that browsers see a CORS error rather than a readable 401. --- docs/wiki/guides/api-authentication.md | 25 ++++- openblade/api/api_auth.py | 71 +++++++++++-- tests/i3/conftest.py | 33 ++++-- tests/integration/test_api_auth_sweep.py | 127 ++++++++++++++++++++++- 4 files changed, 231 insertions(+), 25 deletions(-) diff --git a/docs/wiki/guides/api-authentication.md b/docs/wiki/guides/api-authentication.md index 6038ac6..4979b0d 100644 --- a/docs/wiki/guides/api-authentication.md +++ b/docs/wiki/guides/api-authentication.md @@ -129,12 +129,23 @@ without a credential. | `/inventory`, `/jobs`, `/archive`, `/restore`, `/ltfs`, `/catalog`, `/cartridges`, `/volume-groups`, `/dashboard`, `/storage`, `/nas`, `/virtual`, `/safety`, `/tape-ops`, `/api/*` | token required | open | | `/docs`, `/redoc`, `/openapi.json` | token required | open | | `/health`, `/healthz`, `/readyz` | **open** | open | +| `/aml/proxy/*` | token **and** AML session | AML session | | `/aml/*`, `/iblade/*` | AML session (unchanged) | AML session (unchanged) | `/health`, `/healthz` and `/readyz` stay open on purpose so container health checks, load balancers and uptime monitors keep working without a credential.

The header is client-controlled and the strip matched on segment boundaries, so an attacker could reduce the CLASSIFIED path to any suffix of the real path while Starlette still ROUTED on the original: GET /catalog/aml/instances X-Forwarded-Prefix: /catalog -> classified "/aml/instances" (exempt), routed to /catalog/{file_id} 53 native operations answered something other than this layer's 401 that way. They stopped at 404/405 only because no resource happens to be NAMED "aml" -- a pool, dataset, share or library with that id turned each into live unauthenticated access, and the same trick reopened /aml/proxy. The docstring's safety argument was the tell: it reasoned about route TEMPLATES ("no native route is mounted at a path whose tail is /aml") and forgot that parameter VALUES are attacker-supplied. The test I wrote to pin that invariant had the identical blind spot -- it walked template tails, so /catalog/{file_id} yielded /{file_id} and passed while the hole was live. 274 tests were green over a working bypass. Fix: classify only on scope["path"] minus the SERVER-set scope["root_path"], and delete the header branch entirely -- classification_path no longer takes a header argument at all. Accepted consequence: behind a proxy that announces its prefix only via X-Forwarded-Prefix, the AML surface is classified native and gated. That fails closed, is immediately visible, and is fixed with --root-path (server-side config, not a forgeable header). Tests replacing the blind-spot one: - live attack table asserting the forged header cannot change the outcome - every parametrized native route re-probed with "aml"/"iblade"/"health" substituted into its path parameters - classification_path's signature is pinned to (scope) so nobody reintroduces the header as a convenience Also from the same review: restore the previous app context on fixture teardown instead of leaking it into later modules; correct the fixture comment that claimed no writes reach handlers (the mutation test deliberately makes them); cover require_auth's bearer fallback directly, since the i3 hook moves the session to a cookie in token mode and cannot see a regression there; and fix three doc claims (exemption count, the vacuous description of the sweep, "byte-for-byte") plus document the --root-path requirement. --- docs/wiki/guides/api-authentication.md | 37 ++++-- openblade/api/api_auth.py | 63 +++++----- tests/integration/test_api_auth_sweep.py | 140 +++++++++++++++++++---- tests/unit/test_api_auth.py | 51 +++++++-- 4 files changed, 215 insertions(+), 76 deletions(-) diff --git a/docs/wiki/guides/api-authentication.md b/docs/wiki/guides/api-authentication.md index 4979b0d..1a889ac 100644 --- a/docs/wiki/guides/api-authentication.md +++ b/docs/wiki/guides/api-authentication.md @@ -54,8 +54,10 @@ the method, path and source address only. ### Leaving it off If neither variable is set, authentication is disabled and behaviour is -byte-for-byte what it was before — but the server says so, loudly, once per -start: +unchanged — every status code and body is what it was before; the middleware +short-circuits on its first line.
