#434 ProductOS realignment — superseded by the command model; retained for Phase E reference, not installed
infer-research-from-code
Called by product-keeper during /codify, strictly after
infer-domain-selection-from-code has produced specification/domain-selection.yaml.
Produces one research/{domain}.md per selected domain at
{stm_base}/{issue}/evidence/codify/proposals/research/{domain}.md.
Purpose
In greenfield, research/{domain}.md is copied from the canonical KB during
/specify Stage 3 and extended by research agents. In /codify the codebase
is the evidence surface — no prior product LTM, no web research. This skill
derives each domain's research document from scan-index.json signals attributed
to that domain, the canonical KB entry (when one exists), and any ADR / README
material matching the domain's search patterns. Every output carries the five
KB-extension sections from core/components/memory/standards/rules/kb-extension.md;
where scan evidence cannot populate a section, it is emitted with an inline
knowledge_gap: true marker so /garura:enrich surfaces the gap rather than silently
resolving it. Tier-2 inference, learning_category: domain, sub_category: null.
Input
Receive from the /codify play orchestrator via JSON contract. All paths absolute.
Field
Required
Description
scan_index_path
yes
scan-index.json produced by scan.py.
stm_base
yes
STM root from stm.base-path in .garura/core/config.yaml.
issue
yes
Issue number (STM namespace).
related_proposal_paths
yes
MUST contain the absolute path to specification/domain-selection.yaml. Missing → missing_related_proposal.
scan_index_path exists and parses as JSON with manifests, patterns,
config_files, docs, git. Missing → scan_index_missing.
related_proposal_paths includes an existing domain-selection.yaml.
Missing → missing_related_proposal.
kb_domain_dir exists with ≥1 non-underscore .md file. Missing →
kb_domain_dir_missing.
output_dir is creatable. Failure → output_path_unwritable.
2. Resolution Protocol walk (R1–R3, R4 skipped)
Per core/components/memory/standards/rules/resolution.md. Write every probe
to resolution_trace_path with source, path, outcome, payload.
R1 — STM. Skipped (codify bootstrap). Record reason "codify-bootstrap".
R2 — Product LTM. Probe {product_base}/research/{domain}.md per
selected domain. If present AND LOCKED, propose only when scan evidence
materially conflicts; non-conflicts emit alignment_confirmed: true in
frontmatter and skip the body.
R3 — KB. Per selected_domain in domain-selection.yaml:
inferred_domain_new: false → read {kb_domain_dir}/{domain}.md to inherit
canonical feature IDs, search patterns, and five-section structure.
inferred_domain_new: true → no KB base; structure directly from
kb-extension.md and emit knowledge_gap: true on every section without
a code signal.
R4 — Web. Not invoked. Gaps route through /garura:enrich to a human.
3. Attribute scan evidence per domain
Replay the signal → domain mapping used by infer-domain-selection-from-code,
persisting per-signal evidence under the owning domain:
patterns.framework_idioms tagged for this domain (express → backend-api).
patterns.naming_suffix_counts whose suffix is typical for the domain
(*Controller/*Service → backend-api; *Screen/*Page → frontend-web).
patterns.test_framework_signals whose test files sit under paths
implicated by the domain's source files.
config_files.* associated with the domain (Dockerfile → containerized
runtimes; .github/workflows → engineering-experience; helm → deployment).
docs.adrs whose title contains the domain's search-pattern tokens (from
KB base for canonical domains; derived from slug + triggering readme
excerpt for new domains).
docs.readme_preview sections whose heading or surrounding paragraph
matches the domain's search patterns — record matched span and line.
manifests deps mapped to the domain (Stripe → payments; Auth0/Clerk
→ user-management; etc.).
git.churn_top is used ONLY for Experiential; never as membership evidence.
Every item carries a concrete evidence path (JSON pointer or file path) and,
where applicable, a literal excerpt ≤ 200 chars.
4. Author research/{domain}.md — five required sections
Per selected domain emit Markdown: YAML frontmatter (Section 5), short prose
preamble, five KB-extension sections in order. Each section states
inferred: true and emits inline knowledge_gap: true bullets rather than
fabricating content when evidence is absent.
Inclusion — MUST cite scan evidence (e.g., "Express middleware +
*Controller suffix present → backend-api included"). knowledge_gap: true
is NOT permitted here; a domain without inclusion justification would not
be in selected_domains.
Success Criteria — derived from detected test patterns and assertion
counts where attributable. Otherwise emit one bullet: - knowledge_gap: true — no measurable success criteria observable from scan; defer to /garura:enrich.
Failure Scenarios — derived from try/catch clusters, error-taxonomy
modules, or ADRs naming failure modes. Usually absent; emit
knowledge_gap: true with pointers to insufficient-but-present signals
(ADR titles, churn clusters) as leads.
Cross-Tree Refs — derived from co-change clusters in git.churn_top
and cross-domain imports in manifests / entry_points. If no cross-tree
signal exists, emit - (none observed) — a valid finding, NOT a
knowledge_gap.
Experiential — ADR titles matching search patterns, README notes under
the domain's umbrella, and long-lived churn clusters (git.churn_top
entries with earliest commit > 180 days old). Usage count bootstraps to
0; Last promoted: never. If no ADR / README / churn match, emit
knowledge_gap: true on Scenarios-observed and Common-mistakes sub-bullets.
5. YAML frontmatter meta block
Every file begins with:
---source_type:"inferred_from_code"evidence:-"<scan-index JSON pointer or file path>"-"..."confidence:"high"|"medium"|"low"learning_category:"domain"sub_category:nulltier:2domain:"<slug>"inferred_domain_new:<bool>alignment_confirmed:<bool># true only when R2 hit LOCKED with no conflictknowledge_gap_sections:# explicit catalog of gap-marked sections-"Success Criteria"-"Failure Scenarios"---
Confidence uses the same tiers as infer-domain-selection-from-code, computed
per-domain from the signal count in THIS research file.
6. Write artifacts + decision manifest
Write every research/{domain}.md first, then the decision manifest, then the
resolution trace. The manifest lists every section-level inference — one entry
per (domain, section) derived from evidence AND one entry per (domain, section)
emitted as knowledge_gap: true. Per Decision Surfacing Discipline each entry
carries decision_id, decision_type, tier (low for knowledge_gap, mid/high
for evidenced), grounding_source, recommendation, alternatives,
chosen_reason. Nothing silently resolved.
Output
Primary artifacts — research/{domain}.md (one per selected domain):
YAML frontmatter meta block + prose preamble + five KB-extension sections
(Inclusion, Success Criteria, Failure Scenarios, Cross-Tree Refs, Experiential).
Sections with no code evidence carry inline knowledge_gap: true markers;
sections with evidence cite concrete scan-index pointers or file paths.
Decision manifest — decision-manifest-infer-research.yaml: standard
Garura shape (schema_version, skill, generated_at, decisions[]); one
entry per (domain, section) inference or knowledge_gap.
Emit status: failure with what_failed, detail, and evidence (offending
path / field). Codes:
missing_related_proposal — related_proposal_paths lacks an existing
domain-selection.yaml.
kb_domain_dir_missing — kb_domain_dir absent or empty.
scan_index_missing — scan_index_path absent or not valid JSON.
insufficient_signal — domain-selection declares domains but every
per-domain evidence bundle is empty; would produce pure knowledge_gap
stubs. Fall back to /garura:enrich.
output_path_unwritable — output_dir cannot be created.
Boundaries
Read-only against scan_index_path, kb_domain_dir, and related_proposal_paths.
Emits proposals, never canonical LTM. Promotion from STM proposals to
.garura/product/research/ is handled downstream by /garura:enrich.
Does NOT re-run scan.py, consult the web, or modify the canonical KB even
when inferred_domain_new: true — new canonical entries are created only
after human promotion.
