 ## Details
 
-### 153. Decide whether `src/markdown/` root may import `emit/`, `parse/` or `portable/`, and hold the answer in `.oxlintrc.json` and §The source parts by ADF and format.
+### 153. Return from `parseInlineContent` whether a link opens the paragraph in a spellable form, ask the writer only in `parse/`, and ban `src/markdown/` root files from importing `emit/`, `parse/` and `portable/`, and `emit/` from importing `parse/`.
 
-The writers read each escaped line back through `src/markdown/inline-content.ts`'s scan. A writer
-question put back on that scan's path, such as the opening-link consult `parseInlineContent` takes
-as an argument today, would close the cycle writer → reader → writer and recurse without bound on
-a paragraph opening with a spellable `!adf:link` (§Nothing recurses unbounded). The override for
-`src/markdown/**` bans only `html/`; banning `emit/`, `parse/` and `portable/` for the root's own
-files, with its `ci.sh` probe, extends the decision.
+Today `parseInlineContent` (`src/markdown/inline-content.ts`) takes `openingLinkTakesDirective`, the
+writer's answer, as an argument, and all three callers (`parse/markdown-to-adf.ts`,
+`portable/portable-markdown-to-adf.ts`) pass the same function. The writers read lines back through
+`readLineBack`, which never asks the writer, so nothing recurses today. A root file importing the
+writer would close a module cycle, and a read-back honouring `openingSpellableLink` would recurse
+without bound on a paragraph opening with a spellable `!adf:link` (§Nothing recurses unbounded).
+
+- `parseInlineContent` drops the argument and returns `openingSpellableLink` beside the nodes and
+  the image. One function in `parse/` runs the scan, asks `emit/spelling-questions.ts` and refuses
+  with `spellableLink`; both readers call it, so `portable/` drops its `emit/` import.
+- `.oxlintrc.json`: an override for `src/markdown/*.ts` bans `emit/`, `parse/`, `portable/` and
+  `html/`, since a later override replaces an earlier one's rule; `emit/`'s override also bans
+  `parse/`. `ci.sh` probes both. §The source parts by ADF and format names the root's two bans.
+- A comment on `readLineBack` says a read-back never asks the writer, and the false comment at
+  `inline-content.ts:120` goes. A round-trip test covers a paragraph opening with a spellable
+  `!adf:link`.
+- The reader panel's smaller findings, not in this item: `commonmark/` and root names such as
+  `adjacent-text.ts` do not say which side they serve.
 
 ### 80. Name the node's path and the attribute key when `not-an-adf-document` refuses a node inside the document.
