abcd-intent-quoted-text-create-symmetric

Summary

spc-7 delivers itd-46: abcd intent "<text>" becomes the sub-verb-free create path, symmetric with abcd capture "<text>". The three invocation shapes are now crisp on both ledger commands — bare → read-only status, quoted text → create, sub-verb + id → act on existing. A seeded draft lands in intents/drafts/, abcd intent new survives as a deprecation-warning alias for one transition period, the skill-surface promote flow hands an issue's text to the create verb (engine-backed at last), and both bare renders carry the one-line capture-vs-intent decision rule.

Approach

Mirrors the shipped capture engine where it applies and the spec store where it is stronger:

• Engine: internal/core/intent/create.go — CreateFromText derives a kebab slug (non-alphanumeric runs → -, trimmed, capped 60 chars, validated against slugRe before it becomes a filename), refuses empty/whitespace text before any write, mints itd-N under an exclusive flock on the intents/ directory fd (O_NOFOLLOW, 5s timeout, no lock artifact in the record tree — the spec store's mint-lock pattern, not capture's), scanning max N across all five buckets inside the lock, and writes atomically via fsutil.WriteFileAtomic.
• CLI wiring: newIntentCommand accepts a positional; bare invocation keeps rendering read-only status (the create branch is guarded on len(args) > 0); new is a registered alias that routes to the same create call and prints the deprecation warning on stderr only, keeping stdout byte-identical to the quoted-text form.
• Canonical seeded-draft shape (the record this spec defines): frontmatter id, slug, spec_id: null, kind: null, suggested_kind: null, reclassification_history: [], builds_on: [], severity: minor; body # <title from whitespace-collapsed seed>, ## Press Release (placeholder blockquote), ## Why This Matters (the raw seed text), ## Acceptance Criteria (itd-1 discipline placeholder, no bullets — the human fills them before intent plan), ## Open Questions, ## Audit Notes. The shape passes intent.Validate and the intent_lifecycle record-lint drafts rule by construction (verified by a test that runs the real lint engine).

Adjudications (deviations from the intent letter, recorded not hidden)

1. "Byte-identical to intent new" is historical. No intent new verb ever existed in the Go CLI (it was a pre-rebuild markdown-surface shape); the seeded shape defined above IS the canonical artefact, and the alias produces it identically.
2. Two scope bullets name files that do not exist in this tree — commands/abcd/intent.md and docs/reference/commands.md are old-system references. The intent verb family has no plugin markdown surface at all (pre-existing boundary gap, now on the ledger as iss-105); the routing/table updates those bullets describe have no native counterpart to edit. The AC-level requirements they served (create path reachable, decision rule visible) are met at the surfaces that do exist.
3. Typo-guard asymmetry accepted for now: unlike capture's suspectedTypoedSubcommand heuristic, any non-sub-verb first token is create text, so a mistyped sub-verb files a draft instead of erroring. The ACs do not require the guard; recorded as iss-104 for a symmetry follow-up.

Milestones as delivered

1. Create engine + tests (a9329f8), watched-fail first.
2. CLI wiring: quoted-text route, new alias + stderr warning, bare no-mutation pin, decision rule in both bare renders (c3d4d0a).
3. Skill-surface re-plumb: commands/abcd/capture.md promote now hands the issue body to abcd intent "<text>" and honestly states the related_intents back-link is still verb-less (spc-6 AC3 stays open on it); CHANGELOG entry (7289aa5).

Acceptance-criteria satisfaction

AC as ordered in itd-46 → evidence (tests in internal/surface/cli/intent_cli_test.go unless noted):

1. Quoted text creates a seeded draft — TestIntentQuotedTextCreates; engine: internal/core/intent/create_test.go (TestCreateFromTextSeedsDraft, TestCreateFromTextAllocatesNextID, TestCreateFromTextPassesRecordLint — the real lint engine over the created file). Watched-fail captured before implementation (undefined CreateFromText; CLI unknown command).
2. new routes to create with a clear transition signal — lean (a) as pre-adjudicated: TestIntentNewAliasWarnsAndCreates (stdout identical, deprecation warning on stderr only). Watched-fail: unknown command "new".
3. Bare invocation stays status-only — TestIntentBareCreatesNothing (status render asserted, zero files under drafts/).
4. Promote hands the issue text to the create path — commands/abcd/capture.md promote section now routes through abcd intent "<text>", which the AC1 tests cover end-to-end; the markdown states exactly what promote does and does not do today.
5. The decision rule is visible in both bare helps — TestBareHelpsCarryDecisionRule (both bare renders contain the nitpick→capture / user-facing-change→intent rule). Watched-fail: bare intent render lacked the rule.

Out-of-scope confirmations: no ID-scheme rename, no command merge, mutating sub-verbs keep requiring ids, iss-101/iss-102 code untouched.
