feat: carry the review guidance a threat model needs to be read - #19
Conversation
A threat model that lists threats is not yet a document a reviewer can work through. Three collections close that gap, chosen from the four Kivaar carries that #7 did not specify: - criticality[] records what each priority level means for this project, with worked examples. priority is a schema-owned vocabulary, but where its boundaries fall is a project's judgement about blast radius. A model that ranks threats without recording that judgement leaves its most consequential field unfalsifiable — a reader cannot tell a miscalibrated ranking from an honest disagreement about the scale. - top_abuse_path_links names the abuse paths to read first. Deliberately not derived from priority: editorial order is a judgement, and a list that repeats every critical threat has made none. - focus_paths[] says where in the repository a threat actually lives, and which threats make each location worth reading. No other collection carries that link: components describe what the system is made of and planned_evidence describes what will test it, but neither tells a reviewer what to read. Quantitative policy is configuration, not schema rule — min_criticality_ examples, min_top_abuse_paths, max_top_abuse_paths, and a require_criticality_for_every_priority coverage switch — because the right numbers differ between a small service and a platform. Each bound defaults to zero meaning unbounded. A negative bound, or a maximum below its own minimum, is rejected at load time rather than surfacing later as a document rejection nothing can satisfy. quality_checks is deliberately absent, and the schema documentation says why with the mapping attached: a model's own completeness self-assessment duplicates what this tool proves — coverage across seven collections, requirement resolution, required assumptions and open questions — and a hand-maintained claim can go stale and contradict the validator that ran beside it. What remains are process notes about how a review was run, which belong in the pull request that changed the model. That is schema-or-nothing rather than schema-versus-template, which the issue framed as a third option it is not: unknown members are rejected, so a collection absent from the schema cannot be in a document at all, and a consumer template has nothing to render. New rules are mutation-tested rather than merely written: dropping the level enum, the headline-list minimum, the focus-path validation, and the calibration completeness rule each make the corresponding test fail. Closes #9

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to This change adds new threat-model guidance sections, but valid models can currently render priority calibration in an order that conflicts with the documented schema order, which can mislead readers about how to interpret priorities. Merge should wait for the ordered rendering fix; the configuration documentation also needs a small correction to accurately describe the new policy switch. Sequence Diagram(s)sequenceDiagram

Render calibration entries in schema priority order.
Line 135 preserves document order because it ranges over .Document.Criticality directly. A valid document can list low before critical, but the rendering contract requires critical, high, medium, then low. Build an ordered calibration view from threats.PriorityOrder, and add a fixture with deliberately shuffled entries.

Security review approved the diff but flagged a dependency worth making explicit rather than leaving implicit. A focus path is consumer free text emitted into a table cell through inlineCode, whose pipe escaping is parity-safe only while the value cannot contain a backslash: a backslash immediately before an escaped pipe consumes the escape, and the pipe opens a new column. Nothing said so. Relaxing check.RepoRelativePath to accept backslashes — plausible if someone ever wants Windows-style paths — would silently reintroduce the injection class the risks[].id fix closed. The rejection case now carries that reasoning, and the template says where to look. Mutation-tested by permitting backslashes in RepoRelativePath: the focus-path case fails, and its comment explains why the failure matters rather than just that a string changed. Also list .TopAbusePaths and .FocusPaths among the template data in docs/config.md, which review found missing.
Go review found one real defect. Omitting the criticality array produced five diagnostics for one root cause — the missing array, then every priority level reported as uncalibrated — where omitting assets produces one. The completeness loop is keyed off the fixed priority vocabulary rather than off anything the document declared, so unlike every other coverage rule it had nothing to go quiet against. Presence is now checked inside criticality with an early return, which keeps the legitimate case intact: an explicit empty array with the switch on still reports each missing level, because there the per-level messages are the only signal. Also from that review: topAbusePathLinks re-implemented referenceList instead of calling it, and the field dropped the Links suffix that every other reference field in the model carries, so `grep Links` no longer found them all. Test review mutation-tested the branches I had not, and found four that no test defended: the negative-bound check for both top-abuse-path limits, the guard that treats an unset maximum as no maximum, and the min == max boundary the doc comment explicitly allows. Each is now covered and each was re-mutated to confirm it bites. Added the three new rejection families to the CLI table, whose stated purpose is one representative case per family, and a review-guidance case to the compare table that invites exactly that extension. Documentation review found the coverage table missing its eighth switch while config.md pointed at that table as the complete reference. Added, along with the duplicate-rejection rule the three new list fields inherit — stated once in schema.md rather than per field, since it holds for every declared string list. Folded the "no quality_checks" rationale into Added rather than invent a Notes category this changelog does not otherwise use, and led the criticality rationale with its consequence instead of the abstraction.

Use a backslash immediately before | in the regression input.
The value docs\a|b.md places the backslash before a, not before |. It does not exercise the failure mode described above, where an existing backslash can consume the renderer's generated \| escape and expose a table column. Use docs\|b.md so this test covers the security dependency it documents.

Closes #9
Adds the three collections from Kivaar's model that make a threat model readable rather than merely complete, and documents why the fourth is deliberately absent.
The decision
#9 asked which of four collections belong in the shared schema. Settled with @scottescue as: include
criticality,top_abuse_path_links, andfocus_paths; excludequality_checks.One finding reshaped the question. The issue offered three outcomes per collection — schema, consumer template data, or out of scope. The middle one does not exist: strict unknown-field rejection means a collection absent from the schema cannot appear in a document at all, so a custom template has nothing to render. It is schema-or-nothing.
What's added
criticality[]—level(a schemapriorityvalue, unique),definition,examples[].priorityis schema-owned, but where its boundaries fall is a project's judgement about blast radius. A model that ranks threats without recording that judgement leaves its most consequential field unfalsifiable: a reader cannot tell a miscalibrated ranking from an honest disagreement about the scale.top_abuse_path_links— declared threat IDs, the paths to read first. Deliberately not derived frompriority; editorial order is a judgement, and a list that repeats everycriticalthreat has made none.focus_paths[]—path(repository-relative, never opened),why,threat_links[]. The model's link from a threat to where it lives. No other collection carries it:componentsdescribe what the system is made of,planned_evidencedescribes what will test it, neither says what to read.Rendered as three new sections: Priority calibration, Start here, and Where to look.
Quantitative policy is configuration

quality_checksFour of Kivaar's seven entries are claims this tool already proves:
