# Concept declaration coverage

## Why

`concept_ownership()` in `src/info_tech_canon/generation.py` builds the ownership
index from exactly two sources: each artifact's title, and its
`owned_concepts` frontmatter. A concept that is defined in prose, is referenced
elsewhere by qualified id, and is treated by the corpus as owned is invisible to
it. `concept_ownership_conflict` in `src/info_tech_canon/service.py` can only
fire on what that index contains, so the conflict check covers a minority of the
concepts the canon actually defines.

Measured on the working tree at `209bb5a`:

- the ownership index holds **164 entries** — 81 from artifact titles, 83 from
  `owned_concepts` frontmatter;
- **13 live artifacts declare nothing at all** (T01 measured one more than this
  estimate): itc-core, the kernel map, access-control, data, devsecops,
  governance, information-space, landscape, network, observability, security,
  task, and tagging;
- a single bold-definition pattern (`**Name** is|—`) finds **519 defined terms
  across 15 live artifacts** that appear in no declaration. That pattern is a
  lower bound, not a census: it misses numbered-section definitions and
  table-defined terms.

This is not theoretical. The SecurityCanon boundary review
(`infospace/interfaces/security-canon-boundary.md`) checked SecurityCanon's seven
declared concepts against every InfoTechCanon `owned_concepts` declaration,
found no conflict, and recorded that as evidence. It could not have found
`itc-org:Authority` — defined at ITC-ORG section 10.17, assigned to Organization
by the kernel map, and referenced by qualified id in the governance model —
because ITC-ORG's frontmatter does not list it. The gap was caught by hand in
SECURITY-WP-0001-T03 (finding F-1) and would otherwise have shipped as a false
clean result.

SCOPE.md already concedes that the calculation "does not establish ownership of
every concept in prose". This workplan converts that concession into a measured
number and closes the part of it that matters for federation.

## What this is not

Not a complete ontology, and not automated concept extraction promoted to
canon. Extraction produces *candidates for review*; a concept becomes owned
because a human or a reviewed change declares it, never because a regex found
it. No concept is renamed, moved or removed by this workplan.

## Establish the true denominator

```task
id: INFO-WP-0027-T01
status: done
priority: high
state_hub_task_id: "1e139d9a-8883-59af-a163-1c6da903dad6"
```

Write a candidate extractor over live artifacts (excluding `assimilation/` and
`seeds/`, which preserve source rather than define canon). Cover at least the
bold-definition form, the numbered-section-heading form used by ITC-ORG section
10.17 and ITC-IDENT section 2.10, and terms defined in a table's first column.

Output is a review report under `history/`, listing per artifact: declared
concepts, extracted candidates, and the difference. No corpus change and no
frontmatter edit in this task. The report is the input to T02 and the baseline
the coverage check in T03 measures against.

### Result — 2026-09-20 (T01)

Extractor added as `maintenance.concept_candidates()` with the CLI command
`concept-coverage`, covering the bold, numbered-heading and concept-table forms
over live artifacts, with `assimilation/`, `seeds/` and `incoming/` excluded as
preserved source. Baseline report:
`history/2026-09-20_230456+0200-concept-declaration-baseline.md`.

Measured over 31 live artifacts: 113 concepts declared against 690 defined in
prose, leaving **637 defined but undeclared** — about 16 percent declaration
coverage. The workplan's 519 was the bold form alone; the heading form, which is
what hid `itc-org:Authority`, raises it.

Two corrections to the workplan's own framing. The silent artifacts number
**thirteen, not twelve**: `kernel/itc-core` declares nothing while defining 57
concepts across two forms, and it is the artifact every other artifact imports
from, so T02 should take it first. And the gap is wider than ownership of
obscure terms — `Actor` itself is undeclared in `model/organization`, though
SecurityCanon imports it from there by name with a pinned hash.

Three tests cover the extractor, including one that asserts `Authority` appears
in the organization model's undeclared list, so the F-1 blind spot now has a
regression test. `make check` passes with 49 tests.

## Declare concepts for the thirteen silent artifacts

```task
id: INFO-WP-0027-T02
status: done
priority: high
state_hub_task_id: "b086abf1-3b36-5b05-a8a8-c8b12c9ab280"
```

Add reviewed `owned_concepts` frontmatter to the thirteen live artifacts that
declare none, working from the T01 candidates rather than from the regex output
directly. Each declared concept must be one the artifact genuinely defines, not
one it merely mentions or imports.

Order by federation exposure, not by file size: `kernel/itc-core` first, since
every other artifact imports from it, then access-control, security, devsecops
and governance, since those are the surfaces SecurityCanon,
InterfaceCanon and the small-saas profile reference. The kernel map is a
different case and may end up declaring nothing — it assigns concepts to owners
rather than defining them, and that judgment should be recorded either way.

Expect this task to surface genuine conflicts once the index grows. A conflict
found here is the workplan working, not a regression; resolve each by naming one
owner, as ADHOC-2026-09-20-T01 did for `Scope`.

### Result — 2026-09-20 (T02)

Declarations written for twelve of the thirteen silent artifacts, plus the
map-assigned concepts the Organization Model was missing and the Landscape seed
concepts the extractor could not see. The ownership index goes from **164 entries
to 750**, and undeclared prose definitions fall from **637 to 57**, with
**zero ownership conflicts**. The 57 that remain are the overlaps this round
assigned to another owner: they are imports, and each is recorded in a boundary
review.

`kernel/itc-kernel-map` declares nothing, deliberately. It assigns concepts to
owners rather than defining them, and it is now the only silent artifact — which
the test suite asserts, so a future artifact that declares nothing fails.

The kernel map's concept-owner table was used as the arbiter wherever it assigns
an owner, which resolved most overlaps without new judgment. Fifteen concepts it
does not assign were decided in this round and recorded with rationale.

`itc-org:Authority` — the concept whose absence produced finding F-1 — is now
declared, along with `Actor`, `Ownership`, `Membership`, `Role`, `Responsibility`
and `Accountability`, which SecurityCanon and the identity model already treat as
organization-owned. The regression test asserts the kernel map's assignment and
the declaration agree.

One concept is deliberately left undeclared. The kernel map assigns `Profile` to
Core, but the identity model owns `Profile` under accepted CUST-ADR-006, and
Observability defines a runtime performance profile that the identity boundary
review already disambiguates. Declaring Core's sense would have created the
first real conflict; resolving three senses needs a decision, not a declaration.
It is recorded as open in the kernel boundary review.

### Boundary reviews

```task
id: INFO-WP-0027-T06
status: done
priority: medium
state_hub_task_id: "61ad08c4-d76c-59b9-b8ff-f44500df4bc7"
```

Every artifact that gained a declaration and has an overlap now carries a
`boundary-review.md` beside it, in the shape the identity model has used since
INFO-WP-0021: one row per overlapping concept, naming the owner, the resolution
and whether the kernel map or this review decided it. Eleven were written —
kernel, access-control, data, devsecops, governance, information-space, network,
observability, security, task and tagging. Landscape gained declarations without
overlaps and needs none.

The largest finding is in the kernel review. Core and the Information Space model
restate eight provenance concepts — `Activity`, `AgentReference`, `Alias`,
`DecisionRecord`, `ExternalReference`, `Influence`, `Namespace` and `Source` — in
nearly identical words. Core owns them with the provenance family; Information
Space imports. Four more were decided by disambiguation rather than transfer:
`Label` (Core, with Tagging's display sense kept), `Drift` (Core, with Network's
configuration drift kept), `Summary` (Information Space, with Observability's
metric aggregation kept) and `Attribute` (Data, with Access Control importing for
attribute-based decisions). `Exposure` and `Investigation` go to Security;
`Subject` stays with ITC-ACCESS as SECURITY-DEC-2026-003 records.

## Report coverage instead of asserting completeness

```task
id: INFO-WP-0027-T03
status: todo
priority: medium
state_hub_task_id: "48dbd089-a0bf-5d02-b574-b1acf554f658"
```

Extend the validation coverage report added by INFO-WP-0019 with a
concept-declaration coverage metric: per artifact, declared concepts against
extracted candidates, and a corpus total. Wire the extractor from T01 in as the
measurement, so the number moves when the corpus does.

Decide and record the enforcement level. The recommendation is a warning with an
explicit threshold rather than an error: a hard failure on undeclared prose
terms would fail the corpus today for 519 terms, most of which are legitimately
undeclared prose, and would train reviewers to ignore it. An error is
appropriate for one narrower case — an artifact that declares nothing while
defining concepts that another artifact references by qualified id.

## Re-verify the federation boundaries against the enlarged index

```task
id: INFO-WP-0027-T04
status: todo
priority: medium
state_hub_task_id: "b9313ad5-7cb0-5be6-bc28-196f84640895"
```

Re-run the ownership-conflict check against the enlarged declaration set and
re-verify the two accepted extension boundaries: SecurityCanon's nine owned
concepts and twelve declared imports, and InterfaceCanon's. Record the result in
each boundary file, including the correction if the earlier clean result no
longer holds.

Notify security-canon and interface-canon through the State Hub inbox if either
boundary's evidence changes. This is the task that converts the fix into
restored trust in the earlier reviews.

## Resolve R-3 as the first real use

```task
id: INFO-WP-0027-T05
status: todo
priority: low
state_hub_task_id: "eb02c948-6401-5ef7-a341-4563ee73e00c"
```

Residual R-3 from the SecurityCanon review: `Authority` carries two live senses
inside InfoTechCanon — the recognized right held by an actor (ITC-ORG section
10.17) and an external body compelling disclosure (CARING section 10.7 exposure
mode). Declaring both under T02 forces the question rather than leaving it in
prose.

Resolve by disambiguation, not by rename: CARING's exposure mode is a demand
from an authority, and saying so in one sentence is likely enough. The test is
that a reader arriving from `sec-authority:AuthMode` can tell which sense a given
section means.

Residual R-2 — the proposal to generalise CARING section 32 beyond non-human
subjects — is explicitly *not* in this workplan. It is a semantic change to a
release-candidate standard and needs its own review.

## Done when

The ownership index is built from declarations that cover every concept the
twelve silent artifacts define; coverage is reported as a number that moves with
the corpus; the enforcement level is recorded with its rationale; and both
accepted extension boundaries carry a conflict result re-verified against the
enlarged index.
