field-inventory.md's apm-agent-allowlist and validate.sh's runtime
check already included source_keys as a 4th allowed field, and the
apm-agent.md template already instructed authors to add it for
provenance tracking — but SKILL.md (x2), README.md, ADR-0016, and
deployment-modes.md still described the allowlist as name/description/
model, "nothing else". The template itself even contradicted its own
source_keys guidance with a header claiming "ONLY the three fields
below — full stop" directly above it.
Updates all six locations to document source_keys as the intentional
4th field, resolving the contradiction.
A fresh /code-review of the APM-native authoring retarget (PR #93) found
several correctness bugs beyond the ones already fixed on this branch:
- new-agent.sh silently walked a marker-less subdirectory under $HOME up
to user scope, contradicting its own usage text ("user scope is checked
directly, no walk-up") and risking scaffolding into shared global
~/.claude or ~/.copilot directories instead of the intended local path.
- The hand-copied apm.yml type: manifest detector in new-agent.sh and
new-skill.sh accepted mismatched quotes (e.g. `type: "skill'`) that
validate.sh's regex correctly rejects, and silently dropped a final
apm.yml line lacking a trailing newline — causing the scaffolder and
validator to disagree on scope for identical input.
- Plugin-scope agent frontmatter could still contain the apm-agent.md
template's HTML comments at ship time with no audit signal, yet
apm compile copies frontmatter verbatim and <!-- --> breaks YAML
parsing on both downstream harnesses.
- ADR-0016 asserted agent-audit already implements a SUGGESTION heuristic
for tool-restriction-needing plugin-scope agents; it doesn't.
- agent-audit/README.md still described the old plugin-pair model this
PR replaced with a single-file allowlist model.
- validate.sh's project/user-scope CC-only/Copilot-only field checks and
counterpart-missing check lost their only test coverage when the old
plugin-pair fixture was deleted.
Also replaces an echo-into-sed two-value parse (4 forks per call) with a
single space-separated echo + read in both scaffolders.
Regression tests added for every fix above, including one for a bug this
pass introduced and the test suite caught: an initial two-line
echo + `read` attempt silently dropped the second value, since `read`
consumes only one line regardless of embedded newlines.
Full suite: 158 bats tests, 39 shell-script tests, 12/12 summary
categories, 0 failures.

#89's grilling session surfaced a real upstream gap: APM's agent
primitive has no per-target compile integrator, so tools: and every
Claude-only field (isolation, maxTurns, effort, memory, permissionMode)
would verbatim-copy into Copilot's file with an incompatible or
unrecognized shape. Omitting them entirely is the only option that
never ships a wrong value to a real harness.
Scoped to plugin-scope agent-author only — project/user scope keep
today's Claude+Copilot pair model unchanged. Partially supersedes
ADR-0005 and ADR-0008's plugin-scope clauses (addenda appended to
both); ADR-0009's field-inventory.md mechanism is unaffected, only
its plugin-scope content shape changes.
