 ### Functional
 
-- [sce::Job::JobManager](../../../core/libs/prx/libSceJobManager/Export.cpp) (libSceJobManager) is written from the disassembly of the copies PPSA01474 and PPSA36082 ship in `sce_module`, and `guest_job_manager_tests` passes against both of those modules as well: the memory size formula, the error codes, sync point ordering, the per-sequence limits and the priority order are the original's. Compute sequences submit through `sceAgcDriverSubmitAcb` on the queue their mask bit selects and are checked the same way by `agc_driver_job_manager_compute_tests`: results, ordering against CPU dispatches and sync points, limits and sizes match the two modules. The command stream is simpler than the original's: every compute dispatch is submitted with its own label write and interrupt, where the original batches the label write and rewinds commands it encoded ahead, and the command buffers and labels live on the host heap. The per-queue command size in `calculateRequiredMemorySize` is a constant (104, 148 and 32 bytes per dispatch, sync point and wait), which is what the original measures by running the builders of this project's libSceAgc. A compute dispatch on a CPU sequence throws (the original does not check), and a failing `sceAgcDriverAddEqEvent` throws. `shutdown` throws while a compute sequence has work in flight, a sequence's label total is written as 32 bits, and since the label is host memory no GPU import covers, the driver drains recorded work before each label write. The manager's state lives on the host heap, with only the block header written to the title's memory; the original keeps everything in that block, and a block smaller than 0x2d8 bytes throws here. The worker sleep policy, the spin count and the persistent thread count are validated and stored but change nothing, a factory priority above 1 throws, `shutdown` throws while a thread is blocked in a sequence wait, and using a sequence after its `destroy` throws. `initialize` returns 0 where the original returns the result of its last import (`BG26hBGiNlw`, not resolved to a name), the `sceRazorCpuJobManager*` profiler calls are not made, and a worker thread that cannot be created or configured throws where the original does not check. The order of the sequence and factory virtual functions is read from the modules' vtables only, since no title that calls them has been run
+- [sce::Job::JobManager](../../../core/libs/prx/libSceJobManager/Export.cpp) submits every compute dispatch with its own label write and interrupt, while the original batches label writes and rewinds commands encoded ahead. Command buffers and labels live on the host heap; labels outside a GPU import force the driver to drain recorded work before each write. Completion labels are written as 32 bits; wrap behavior is unverified. The per-queue command-size formula uses fixed builder sizes of 104, 148 and 32 bytes per dispatch, sync point and wait.
+- The [manager](../../../core/libs/prx/libSceJobManager/Export.cpp) keeps its state on the host heap rather than in the caller's block, apart from the block header. Blocks smaller than 0x2d8 bytes throw. Worker parking uses a host condition variable and mutex rather than the original semaphore and atomic queues; console scheduling and spin timing have not been measured.
+- [Sequence and manager operations](../../../core/libs/prx/libSceJobManager/Export.cpp) throw on a compute dispatch on a CPU sequence, a failing `sceAgcDriverAddEqEvent`, a factory priority above 1, and use of a destroyed sequence. `shutdown` throws while compute work is in flight or a caller is blocked in a sequence wait. Worker creation and attribute failures throw where the original does not check.
+- [`initialize`](../../../core/libs/prx/libSceJobManager/Export.cpp) returns 0 instead of the result of the original's final import (`BG26hBGiNlw`, unresolved). The `sceRazorCpuJobManager*` profiler calls are not made. Sequence and factory virtual-function order is recovered from module vtables; no calling title has been run.
+- The [fallback](../../../core/libs/prx/libSceJobManager/Export.cpp) and Windows [reference runner](../../../tools/test_job_manager_reference.py) disagree: the runner times out in the node-pool exhaustion fixture against the PPSA06888 module with the host kernel; the fallback returns `SequenceInvalid` and recycles its nodes. The cause remains unverified. Original-module execution on Linux and console timing equivalence are not covered by this runner.
