docs: assignment-authoring + grading-types guides for instructors - #20
Merged
Conversation
Official lectern guidance on how to author a coding assignment so it is gradeable the same disciplined way every time: a student-facing spec, an ISA rubric/skill, and an automated grading path wherever a deliverable is machine-checkable, with one reconciled point split. Covers all three grading mechanisms — gradebox (sandbox/runnable), oracle (verify-by-proof, receiving-end contract + course-token CI), manual — plus academic-integrity authoring patterns (forcing functions/canaries, hash forcing, dynamic_flag, flag-don't-deduct) and the academic-use/IP posture (private images for third-party assets, source-available tooling licensing). Generic; Pokémon-malware lab as the worked example. Linked from SKILL.md.

Enrich the academic-integrity authoring patterns: significant base divergence (Super Star Trek technique) and per-student individualized artifacts (exam per-student-serial pattern applied to labs; grader regenerates from bound id, trusts nothing in the repo).

… type A plain-language, use-case-driven selection guide for instructors and ISAs: a decision tree plus per-type 'use when / don't use when', worked CECS examples, authoring entry points, and honest maturity. Written for CS faculty without a security/OS background; points to oracle's docs/grading-model.md for mechanics and keeps the deep specialist docs linked as 'dig deeper' for OS/computer-security depth. Cross-linked from SKILL.md (Authoring assignments) and from assignment-authoring.md Step 0 + See also.

What
Stands up the assignment-authoring guide for lectern, plus a new instructor's selection guide for the grading types. Three commits:
docs/assignment-authoring.md— the generic graders'-contract procedure for any coding assignment (student-facing spec + rubric/skill + grading-mechanism choice + integrity patterns + academic-use/IP posture; Pokémon-malware as the worked example).docs/grading-types.md— a plain-language, use-case-driven guide to choosing a grading type, written for CS faculty without a security/OS background: decision tree, per-type use when / don't use when, worked CECS examples, authoring entry points, a cheat sheet, and honest maturity.Layering
grading-types.mdis the instructor which-do-I-pick layer. It points to oracle'sdocs/grading-model.mdfor mechanics and keeps the deep specialist docs (gradebox.md,exploit-verification.md,ADDING_AN_ASSIGNMENT.md,COMPLIANCE.md) linked as "dig deeper" for OS/computer-security depth — nothing dumbed down, an accessible top added.Cross-links
SKILL.md(Authoring assignments) → start atgrading-types.mdassignment-authoring.mdStep 0 + See also →grading-types.mdand oraclegrading-model.mdMaturity (kept honest)
Oracle verify-by-proof = in production · gradebox code-running = built & stress-tested · exploit-verification = validated end-to-end · binary-artifact/ROM = foundation merged, full grader in design · manual rubrics = in production.
