The answer to the capability question was conditional: keep both fields if
they carry the required/observed distinction, fix the terminology if they do
not. They did not.
Section 9 opened with "records known requirements or observations", mixing
both in one field — `models` was observational ("known to be compatible or
evaluated") while `capabilities` was prescriptive ("expected from the
execution environment"). Section 10 then described dependencies as what a
prompt "expects". Both fields said expected, so the overlap was real
ambiguity rather than redundancy, and the fix is terminology.
`dependencies` now means **required**; `compatibility` means **observed**. A
consumer must not refuse to run a package because its environment is absent
from a compatibility list. The same capability name may legitimately appear in
both: required to run at all, and separately observed to work well on
particular models. `compatibility.aliases` records the same capability under
other names, so a consumer can recognize a requirement its environment labels
differently.
Dependencies now have three kinds, separated by what the format can do about
them: `prompts` it resolves by id and version; `context` names what it does
not package at all; `capabilities` are what the environment must be able to
do. Context entries use `name` rather than `id`, because nothing can look them
up, and `description` is required because nothing else can explain an
unpackaged dependency. A capability takes no version and no
`requirement: generate` — it is not an artifact and cannot be fetched, pinned
or generated. Capability names are free-form kebab-case, validated for shape
and not membership, exactly as tags are.
Section 10.1 also draws the line the format had never stated: an input is
content the caller passes for one use; a context dependency is a standing fact
about the environment.
Spec: 9 rewritten, 9.1 and 10.1 and 10.2 new, 10 reframed, 18 (rules 19-20),
4 updated. Former 10.1/10.2 renumbered to 10.3/10.4 with cross-references.
Reference CLI: validate_capabilities, validate_context_dependencies, and a
`resolve` section listing required capabilities and context under "this tool
cannot verify these" rather than implying it checked. Tests 51 -> 65.
Also drops an invented `session-review` capability from the example package in
favour of an honest `long-context` observation.

practice/house-style
A type: fragment package: a reusable block meant to be included by other
packages rather than used on its own.
examples/pqrst-estimate composes it:
dependencies:
prompts:
- id: practice/house-style
version: ">= 0.1.0"
requirement: required
inputs:
- name: house_style
required: false
default:
include: practice/house-style
Inclusion is deterministic — the fragment's template is rendered and inlined as
text, with no model involved — so the reference CLI performs it during
resolve. See CannedPromptFormat-v0.1.md § 10.4.
Its tone parameter is inherited from the including package when that package
declares one, and otherwise falls back to the default here.
