--ISSUE Content-Type: application/sprints Sprints: --ISSUE Content-Type: application/modules Modules: - Name: sekft Path: . --ISSUE Content-Type: application/bugzilla URL: https://bugs.code.tiararodney.com/rest Mappings: - Module: sekft Product: sek Component: sekft --ISSUE Content-Type: application/issue ID: 1 Type: feature Title: Package sekft as an installable namespace package Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: Turn the flat trainer scripts into an installable tiararodney.sekft namespace package: src layout, pyproject with the abstract posix-sdc dependency and an optional gpu extra, console scripts, a Pipfile pinning posix-sdc as a local editable override, and tox environments. --ISSUE Content-Type: application/issue ID: 2 Type: feature Title: SFT trainer with chat-template render and assistant-only mask Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: Add the supervised fine-tuner: render trajectories through the tokenizer's own chat template (matching serving), canonicalise turns (fold system, merge consecutive), derive an assistant-only loss mask by token-prefix differencing, and train a QLoRA adapter. --ISSUE Content-Type: application/issue ID: 3 Type: feature Title: Behavioural evaluator Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: Add the behavioural eval: load base plus LoRA adapter, drop it into held-out scenarios with no scaffold, drive them through a local operator that renders with the model's chat template, and report reach/terminate/checker rates. --ISSUE Content-Type: application/issue ID: 4 Type: feature Title: Resident-base train/eval harness Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: Add the resident harness that loads the 14GB base once and keeps it hot, training fresh LoRA adapters and evaluating them without reloading the base, for the slow-OcuLink iterate loop. --ISSUE Content-Type: application/issue ID: 5 Type: feature Title: Pipeline overview README Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: Document the sekft pipeline: the trainer, evaluator, and resident harness; how they consume the posix-sdc dataset; the render contract; and how to run on the GPU box. --ISSUE Content-Type: application/issue ID: 6 Type: feature Title: Test suite: unit and smoke Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: Add a pytest suite: torch-free unit tests for the render canonicalisation and assistant-only mask (fake tokenizer), and smoke tests that the console entry points respond to --help without the GPU stack. --ISSUE Content-Type: application/issue ID: 7 Type: feature Title: Add GPL-2.0 license and drop the relocated Dockerfile Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: License sekft under GPL-2.0 (canonical text plus pyproject metadata) and remove the dash Dockerfile, which now lives in posix-sdc under docker/alpine-dash. --ISSUE Content-Type: application/issue ID: 8 Type: feature Title: Refresh docs for the packaged trainer Status: done Priority: medium Created: 2026-06-16 Module: sekft Relationships: Description: The README still describes sekft as the data factory (generate/rollout/dashdocker/taxonomy/schema), which all moved to posix-sdc. Rewrite it as the trainer (sft/eval/resident) that consumes posix-sdc, and update the module docstrings to console-script invocations and the chat-template render contract. --ISSUE Content-Type: application/issue ID: 9 Type: feature Title: Type-check the package under mypy strict Status: done Priority: medium Created: 2026-06-17 Module: sekft Relationships: Description: Make the lint env honestly pass: add mypy as a dev dependency, ignore_missing_imports for the ML libs, fully annotate eval/resident/sft (including the inner operator callables), and ship a py.typed marker so the Typing::Typed claim is real. --ISSUE Content-Type: application/issue ID: 10 Type: feature Title: structured logging for the trainer (sft) Status: done Priority: medium Created: 2026-06-17 Module: sekft Relationships: Description: The trainer is nearly silent: outside an example count and a save line it prints nothing through tokenizer load, the ~14GB base-model load, example building, and the whole training loop, and trajectories dropped for exceeding --max-len or having an empty loss mask vanish without a trace. Add a small shared logging setup (_log.py, stderr so stdout stays clean for results) and a module logger; give sekft-train -v/--verbose and -q/--quiet. Log the run config and each phase, report dataset accounting (keepers -> usable, with counts dropped for length / empty-mask and a warning when any are dropped), and raise transformers' verbosity during training so the per-step curve shows. Apply to train() and inspect(). --ISSUE Content-Type: application/issue ID: 11 Type: bugfix Title: operate_rate can sum a None (eval + resident) Status: done Priority: medium Created: 2026-06-17 Module: sekft Relationships: Description: operate_rate computes sum(t.steps > 0 and t.meta.get('clean') for t in rows). The 'and' yields the right operand when steps>0, so if meta lacks the 'clean' key it yields None and sum() raises TypeError at runtime; mypy (now that posix-sdc ships py.typed and Trajectory is typed) flags the generator item type in eval.py:83 and resident.py:157. Wrap the predicate in bool() so it counts trajectories that operated and are clean, fixing both the type error and the latent crash.
