Summary

dev-docs/ARCHITECTURE.md had grown to 818 lines, 475 of which (58%) were 33 inline ### Decision: entries with no IDs, dates, or status. This PR moves each decision into its own architecture decision record under dev-docs/adr/ and leaves the architecture doc as pure narrative (343 lines).

  • One file per decision (0001–0033), numbered chronologically by the date each decision's heading first appeared, recovered from git history (git log --follow -S per heading). Bodies are migrated verbatim — the only content change is one relative link retargeted for the new directory depth (MODELS.md → ../MODELS.md in ADR-0022).
  • dev-docs/adr/TEMPLATE.md: a concise template for future ADRs — ID/date/status header plus Context, Decision, Consequences.
  • dev-docs/adr/README.md: index table (ID, date, title, status) plus instructions for adding and superseding decisions.
  • ADR-0034: a meta-ADR recording this convention itself.
  • dev-docs/ARCHITECTURE.md: decision blocks removed; a new "Decision Records" section points at the ADR directory.
  • CLAUDE.md / AGENTS.md: the four decision-log references (Non-Negotiable bullet, "say so when you decline", feature-checklist Documentation bullet, Reference Docs table) now point at dev-docs/adr/; the two files remain byte-identical from line 4.
  • internal/sbom/origin_test.go: a failure message that named the removed decision-log entry now names ADR-0033.

Verification

  • Content-loss check: every non-blank line removed from ARCHITECTURE.md appears in exactly one ADR (0 missing, 0 extra); grep -c '### Decision:' dev-docs/ARCHITECTURE.md → 0.
  • All relative links in dev-docs/adr/*, dev-docs/ARCHITECTURE.md, CLAUDE.md, and AGENTS.md resolve.
  • diff <(tail -n +4 CLAUDE.md) <(tail -n +4 AGENTS.md) → empty.
  • make test passes.
  • make generate untouched: the generator only writes under docs/ and never sweeps dev-docs/.

🤖 Generated with Claude Code

Summary by CodeRabbit

  • Documentation
    • Moved architecture decisions into individually numbered Architecture Decision Records (ADRs).
    • Added an ADR index and reusable template for recording and revising decisions.
    • Updated architecture guidance and documentation checklists to reference the ADR workflow.
    • Added ADRs documenting existing architectural decisions, with links and statuses for easier discovery.

Move the 33 inline "### Decision:" entries out of dev-docs/ARCHITECTURE.md
(where they made up 58% of the file) into dev-docs/adr/, one ADR per
decision. Bodies are preserved verbatim; each file gains an ID, a date
backfilled from the git history of the heading that introduced it, and an
Accepted status. Numbering is chronological by that date.

- dev-docs/adr/TEMPLATE.md: concise Context/Decision/Consequences template
  for future ADRs
- dev-docs/adr/README.md: index table plus instructions for adding and
  superseding decisions
- dev-docs/adr/0034: meta-ADR recording this convention
- dev-docs/ARCHITECTURE.md: decision blocks removed, new Decision Records
  section points at the ADR directory
- CLAUDE.md / AGENTS.md: the four decision-log references now point at
  dev-docs/adr/ (kept byte-identical from line 4)
- internal/sbom/origin_test.go: failure message names the origin ADR
  instead of the removed decision-log entry

📝 Walkthrough

Walkthrough

Architecture decisions moved from dev-docs/ARCHITECTURE.md into numbered ADR files. New ADR guidance, an index, and a template were added. Agent instructions and an origin test reference the new ADR locations.

Changes

Architecture decision records

Layer / File(s) Summary
ADR framework
dev-docs/ARCHITECTURE.md, dev-docs/adr/README.md, dev-docs/adr/TEMPLATE.md
The architecture document now links to individual ADRs. The ADR README defines numbering, indexing, and superseding. The template defines required metadata and sections.
Migrated ADRs 0001–0017
dev-docs/adr/0001-*.md ... dev-docs/adr/0017-*.md
The first 17 architecture decisions now exist as individual ADR documents.
Migrated ADRs 0018–0027
dev-docs/adr/0018-*.md ... dev-docs/adr/0027-*.md
ADR-0018 through ADR-0027 document enrichment, audit, configuration, remediation, warnings, input limits, and diff behavior.
Migrated ADRs 0028–0034
dev-docs/adr/0028-*.md ... dev-docs/adr/0034-*.md
ADR-0028 through ADR-0034 document CLI presentation, integrations, SBOM behavior, package origin, and the ADR migration.
Guidance and test references
AGENTS.md, CLAUDE.md, internal/sbom/origin_test.go
Agent instructions now require ADRs for architecture decisions and decline reasons. The origin test points to ADR-0033.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to a7fb8

This documentation-only change is broadly mergeable, but the ADR index and numbering need alignment, and one ADR should either match the implemented path-handling guarantee or narrow its wording to avoid misleading maintainers.

…ical

The author date of 58dfdc6 (2026-08-25, +00:44 -0400) is a timezone
artifact; the decision landed on main 2026-08-24 (-0700), the same day the
meta-ADR was recorded, so the index stays chronologically ordered.

- Line 8: Update ConsolidateGraphs so location rebasing applies to results from
every detector origin, including externalDetector.ResolveGraph and bundled
plugins, before consolidation and diff matching. Ensure detector paths are
converted from each subproject’s working-directory coordinates to
repository-relative paths while preserving existing no-op behavior for root,
absolute, and already-prefixed paths; otherwise narrow the ADR guarantee to
core-detector output and document the external-detector contract.

In `@dev-docs/adr/0034-decisions-are-recorded-as-individual-adrs.md`:
- Around line 3-4: Resolve the chronological inconsistency between ADR-0034 and
ADR-0033 by determining whether ADR dates or IDs are authoritative, then either
renumber the affected ADRs and update all index and cross-references or correct
ADR-0034’s date to its actual first-recorded date. Preserve the numbering rule
stated in the ADR guidance.
