Post (slot Thu 2026-11-05): When Should You Not Use an Executable Business Ontology?

Carries item B of #236. #236 keeps item D; item A is PR #260, held to 2026-11-03; item C is split into its own card in the same stroke.
Filing-gate category: ③ maintainer-directed task. The maintainer, PM session chat, 2026-10-15: 「立卡处理」 on the evaluation that proposed this post. #236 split it out per its own body: one dev per post.
Who acts: repo:www.objectos.ai · seat 2 (objectstack-ai/objectstack#23827). It dispatches on filing.
Dedupe: all 113 issues on this repo, open and closed, REST, 2026-10-16T07:34Z. when (should you )?not (to )?use|when-to-use|not a fit: 2 hits, #236 (the parent) and #235 (closed; its /compare/ page carries a "Not a fit today" list — see the overlap fence below).
Dispatch tier: ceiling (CONTRACT_REVIEW_TIER) — reason: the maintainer's 2026-10-15 ruling that article cards dispatch at the ceiling tier.

The post

"When Should You Not Use an Executable Business Ontology?" (working title, query-shaped). Slot Thu 2026-11-05, merged on that day by the seat.

Source of truth: objectstack content/docs/concepts/when-to-use.mdx — good fits, the not-a-fit list, the five questions before you start, what you get in the first weeks and after a year — and content/docs/concepts/compare.mdx concessions.
Steelman each non-fit (writing rule 7): core ERP or finance of a large enterprise, integration-heavy workloads, analytics over data lakes, algorithm-heavy domains, certified-platform requirements. For each, say what the reader should use instead and why that is the right call. The product appears only as the subject of its limits.
Overlap fence. /[lang]/compare/ (PR content(pages): add the /ontology/ pillar and /compare/ with a "when not to use it" section #258, landed 2026-10-16) already lists these non-fits and the five questions in one line each. This post must go further: a concrete scenario per non-fit, the cost of choosing wrong, and a decision checklist the reader can run on their own case. Link the page; do not restate it. Vary the opening, structure and proof against Post (slot Thu 2026-10-08): What Does "The Ontology Is the Software" Mean? An Executable Business Ontology, Defined #211, content(blog): executable ontology vs knowledge ontology — post 2 of the positioning wave (slot 2026-10-20) #244, content(blog): what makes a business app AI-writable — post 3 of the positioning wave (slot 2026-10-22) #245, content(blog): agent-operable apps — every object and action an MCP tool under the user's permissions (post 4, slot 2026-10-27) #237 and PR content(blog): What Do AI Models Lack in the Enterprise? A World, Hands and a Fence (slot 2026-11-03) #260 (writing rule 9).
Proof artifact: a decision table (workload → fit / not a fit → what to use instead → the deciding fact), with each row sourced.

en and zh-Hans authored (the Chinese re-derived, not translated); zh-Hant generated. Facts verified against objectstack origin/main on the day of writing. No token figures as positioning (#209 Q5).

Done looks like

Draft PR Refs #236 (item B) with Fixes this card. Gates pnpm content:lint, pnpm content:lint --published, pnpm check, pnpm build, pnpm seo:smoke green. Browser check en + zh-Hans at 1440×750 and 390×844. SVGs rendered at native size and at phone width and looked at.

  "deviations": "(1) zh-Hans does not link this site’s /compare/ or /ontology/ pages. Measured before the first commit: with [对比页](/zh-Hans/compare/) in the zh-Hans body, scripts/gen-zh-hant.mjs leaves the link untouched in the generated zh-Hant file (prints: left 2 /zh-Hans/ link(s) as-is — no provable Traditional build) and pnpm content:lint exits 1 with a blocking Cross-locale internal link error because /zh-Hant/compare/ IS built; linking /en/compare/ from zh-Hans fails the same rule the other way. The zh-Hans text names the page without a link and links the objectstack concept pages instead; en links /en/compare/, /en/ontology/ and /en/security/. The generator fix is outside this card’s file surface (see out_of_scope_findings and open_questions). (2) First build failed with NoImageMetadata: Astro’s SVG size probe validates the root tag inside the first 1000 bytes and the self-check SVGs’ long aria-label pushed the root tag to 1263/1300 bytes; fixed in 64a1442 by moving the description into a desc element (root tags now 261/236 bytes). (3) The first decision table had four columns, which scroll at 390 under the layout’s 104px per-column floor (417px of content in 358); reduced to three columns in f9955fa with the fit verdict merged into the use-instead cell. (4) The first lock run joined its parts with semicolons and got a batch-last-exit verdict; discarded, re-run with && (VERDICT command-exit 0 is the one quoted). (5) The first preview server was pnpm-wrapped and its re-exec survived the parent’s SIGTERM; found by cmdline and killed by exact PID; later servers were spawned detached and killed by process group; ports probed down afterwards, nothing of mine left running. No label writes, no MCP writes, no PATCH of the PR body. Commit trailers are model-free (Co-Authored-By: Claude; Claude-Session URL).",
