feat(P0b): Markdown jobspec parser + dispatcher + fuzz harness (REQ-064,067)
P0b — Canonical Markdown+frontmatter jobspec parser (R-013/R-014).
Parser (internal/jobspec/markdown.go, REQ-064):
- WorkloadSpec/RuntimeBlock/PortSpec/VolumeSpec types. ParseMarkdown
hand-rolled YAML frontmatter (no yaml.v3 dep). Kind validation (Job/
Service/DaemonSet per R-012). BOM-stripped frontmatter, byte-exact body
preservation (R-015) via the fuzz harness.
Dispatcher (internal/jobspec/dispatch.go, REQ-064):
- ParseFile/Dispatch routes on extension: .md->Markdown, .yaml/.yml->
Markdown-with-empty-body, .hcl->ParseHCL adapter. HCL adapter converts
Spec{Job,Tasks} to *WorkloadSpec (Kind=Job, Runtime.one_of=process).
Backward compat preserved (REQ-090) — orca job run old-spec.hcl works.
- Legacy Parse renamed ParseHCLLegacy, marked // Deprecated per R-013.
Fuzz harness (internal/jobspec/markdown_fuzz_test.go, REQ-067, R-015):
- FuzzParseMarkdownRoundTrip with 10 seed corpus entries (CRLF, BOM,
no-frontmatter, only-closing-separator, code-fence ---, trailing
whitespace, empty body, etc). Asserts byte-exact body round-trip.
Tests: markdown_test.go (19 tests), dispatch_test.go (17 tests), fuzz
(10 seeds). jobspec package 89.2% coverage. cli 81.8% (no regression).
18 packages pass, 20 bats pass, gofmt clean, verify-reqs 90 consistent.
