Claude — info-tech-canon: the door, and the first thing to walk through it

Who I was

I was a Claude Code session working with Bernd on info-tech-canon, the markdown-first semantic canon. He had created a directory called incoming/, dropped two files into it, and asked for two things in one breath: document how we process inputs like this, and now process these.

That order matters. I was asked to build the door before walking through it — and then to walk through it, which is the only way to find out whether a door you designed actually opens.

Contribution

The practice — infospace/assimilation/intake-and-assimilation-practice.md. Five stages from drop zone to versioned canon: incoming/ → frozen source snapshot → the Minimal Assimilation Profile → a human disposition gate → canon transformation and registration → a semantic version bump with change notes. It is anchored to what InfoTechCanonCore already says (§14 assimilation, §8.13 ChangeRecord, §8.14 DecisionRecord, §27.4) rather than inventing a parallel process, and it ends in a checklist, because a practice nobody can run at 11pm is a document, not a practice.

The first run through it — the Information Technology Capability Canon v0.1, a 1,150-line draft with a companion YAML, absorbed under disposition adapt as InfoTechCanonCapabilityModel (ITC-CAP): 41 capabilities, a D0–D7 provision maturity scale, C/S/N/I/P resource classes, canon 0.1.0-scaffold → 0.2.0.

Then, a turn later, canon 0.2.1: splitting one navigation domain to close the one blocking question the assimilation had left open.

What I would want remembered

The input asked to be adopted, and adopting it as-is would still have been wrong. ITCC's own §15 says it is meant to be reconciled into InfoTechCanon. That is an invitation, not a verdict. Read closely, it carried a second definition of Profile colliding with Core §8.6, a proposed sibling landscape model duplicating one the canon already had, and a maturity rule stated correctly with no object to attach it to. Four changes on adoption — rename, reject, make the provision explicit, bind requirements to the existing demand model — and the same content stopped competing with the canon and started extending it. Assimilation is not adoption is written in Core §6.7. This session is what that sentence costs when you actually honour it.

Anchors were the load-bearing invention. A capability catalog is the kind of artifact that quietly becomes a second ontology: forty-one plausible nouns, each one a little bit about identity, or data, or policy, and within a year nobody knows which document owns Policy. So every capability must name the canon model(s) that own the concepts it exercises, or carry an explicit note saying it has no owner. That single required field turns "single canonical owner" from a principle in a kernel document into something a validator could enforce — and it made the seven genuinely unanchored capabilities visible as a known weakness instead of an invisible one.

Preferring the cheap fix is not the same as preferring the small one. Two capability ids used a governance. prefix inside a domain named security. The tempting fix was renaming them into line. But ids in this model are declared durable interfaces, and the domain grouping is declared navigation_only — so renaming would break two real interfaces to tidy a table of contents, while splitting the domain fixed the same defect and touched no id at all. I said so, recommended it, and let Bernd decide. He did. Six lines of YAML, a patch version, nothing downstream disturbed.

A validator that only says ok is not the interesting half. My first registration passed structurally and then failed on consistency_cycles: 2 — I had written relationship edges in both directions between the model, its catalog, and its assimilation record. The graph metric caught a modelling mistake that no file-existence check would have. Whoever built that metric into this repo was right, and I would not have found it by reading my own work.

Durable legacy

• infospace/assimilation/intake-and-assimilation-practice.md — the door; stage 4 records the repo's registration machinery (three registries, regenerate, validate, and the artifact counts hardcoded in tests/), which is the part that cost this session the most to learn
• incoming/README.md — drop-zone rules, and the incoming/ vs demand/ vs seeds/ distinction, so an input that is really a need gets routed instead of assimilated
• infospace/assimilation/it-capability-canon/ — frozen source snapshot, 18 extracted concepts, comparison matrix, 26 mappings, 8 proposed changes, 7 open questions, two decision records
• infospace/models/capability/ — ITC-CAP and its machine-readable catalog; prose and data separated so they cannot drift
• CHANGELOG.md — the repo's first, with the versioning rule stated at the top
• ITC-WP-0014 — the promotion path, honestly scoped

Visual prompt

A cartographer's workshop at night, pale gold light on deep indigo. A large map of a known territory is pinned across the wall — coastlines, regions, everything already named. On the table lies a newly arrived chart of the same ground, drawn by another hand in another convention. The cartographer is not copying it onto the map and not throwing it away: they are running a fine thread from each landmark on the new chart to the region on the old map that already owns it, and where a thread finds nothing to tie to, they leave it hanging, visible, deliberately unfinished. Beside them a sealed envelope holds the original chart, untouched, kept as evidence. Patient, exacting, unhurried. Precise technical illustration, dark indigo background, warm gold and teal accents, no logos, no readable text, square composition.

Handoff

To whoever picks this up:

ITC-CAP is proposed, and it should stay there until a consumer uses it. Three gates remain in ITC-WP-0014: the contract schema (T02), formal mapping artifacts (T03), and a real capability requirement set expressed in the small-SaaS profile (T04). T04 is the one that matters. The first three can all be completed while the model is quietly wrong; only a consumer trying to state what it actually requires will reveal whether the vocabulary works.

Seven capabilities have no anchoring model — commerce.metering, commerce.billing, commerce.payment, and four intelligence.*. That is recorded as OQ-5, not hidden, and it is fine at proposed status. It stops being fine the moment a consumer needs structure rather than ability, because there is nothing behind those ids: no invoice, no entitlement, no evaluation. Resist filling the gap with a model nobody has asked for.

The artifact counts in tests/ are a tripwire, and I left it armed. Adding any canon artifact breaks five tests on hardcoded numbers. I updated them rather than loosening the assertions, because the tripwire is doing real work — it makes registration a deliberate act. Just know that it will fire on you, and that the fix is one line.

OQ-3 is the one I would take up next if the canon were mine. ITCC proposed distinguishing intended / declared / applied / observed / assessed state, so a provider can claim D5 while an assessment concludes D4 without corrupting the model. I deliberately did not adopt it inside the capability model, because adopting it in one model creates a local dialect. That distinction is worth having canon-wide, at the kernel — controls, access maps, and network policy all want it. It is the most valuable idea in the source document and the one I declined to take.
