Closes the gap that made optional inputs unusable: rendering rule 5.1(4)
made any unresolved placeholder an error while inputs had no `default`, so
an input marked `required: false` and referenced from the template failed
every render in which the caller omitted it — including the spec's own
section 4 example.
Section 10 already carried the derivation mechanism (`requirement: generate`,
resolution deliberately undefined), so a derived default needed a binding
rather than a new concept: the input's default names a declared prompt
dependency.
Spec:
- 5.1 rewritten as "Resolution and rendering". Resolution may be
non-deterministic and must report what it derived; rendering is
deterministic and must not derive. A tool that handles only supplied
values and static defaults is stated to be conforming.
- 6.1 (new) covers both declaration forms. Reference form is preferred, with
the reason stated — an inline prompt is anonymous, so unversioned,
unprovenanced and un-evaluable — and validators should warn when a
published package derives inline.
- A derived default may declare a static fallback `value`. Without one the
input stays unresolved, which is an error; derivation never silently
yields empty content.
- 4, 10, 18 (rules 11-13), 19 (two new MUST NOTs), 21 updated accordingly.
Reference CLI:
- New `resolve` verb reporting the origin of every value.
- `Resolution` dataclass and `resolve_inputs`; `resolve_values` kept as a
wrapper so existing callers are unaffected.
- `render` refuses with a specific error naming underivable inputs rather
than substituting empty text.
- Tests 3 -> 11. Example package lifecycle re-verified end to end.
INTENT.md is unchanged: splitting resolve from render preserves success
criterion 4 (deterministic rendering) as written.

Register canned-prompts under agents / practice (topic
c1d199b6-55ee-4db6-b49e-257a9f0f15ac, workplan prefix CANP-WP) via
`statehub register`, then replace the generated placeholders with
repo-specific facts.
- SCOPE.md: real boundaries drawn from INTENT.md's deliberate boundary,
current state (spec v0.1 + reference CLI, 3/3 tests pass, example
round-trips), and the developer workflow.
- AGENTS.md: drop the unresolved {CREDENTIAL_ROUTING} template token left
by the generator.
- CANP-WP-0001: bootstrap tasks closed.
- CANP-WP-0002: new workplan carrying the five § 23 open questions promoted
from "experience will decide" to "decide for v0.2" — optional-input
defaults (static or derived), registry namespaces/ownership, prompt
composition, canonical eval schemas, typed context/dependency contracts —
plus two reference-implementation conformance defects found in review
(prerelease versions sort as newest; copy_immutable packages the whole
source directory).
Also lands the previously untracked seed: INTENT.md, the CPF v0.1 spec,
the reference CLI, and examples/pqrst-estimate.
