• Shape: src/markdown/portable/adf-to-portable-markdown.ts:289 reduceTaskList: the loop lost its nested accumulator and nestIn; line 303 packs the split and a merge into one expression
• Shape, Locality: src/markdown/portable/task-list.ts:8 splitTaskList: a standing flag across iterations and stands overwritten mid-iteration; heldTask says little
• Locality: src/markdown/parse/markdown-to-adf.ts:86 readBlocks: bulletNode returns a schema-breaking task list that its caller splits, and neither says so

Inherited architect, decided by:

• Self-sufficiency: src/markdown/portable/task-list.ts:5 splitTaskList: the comment states the schema constraint, not the rule; the loop must be traced by hand

• Locality: src/markdown/portable/adf-to-portable-markdown.ts:311 reduceTask: dropping blankedCode rests on a guarantee neither unit states
• Locality: src/markdown/portable/adf-to-portable-markdown.ts:317 nestIn: two hand-mirrored halves of one rule became one function
• Self-sufficiency, Locality: src/adf/inline-nodes.ts:12 inlineNodes: takesMarks: false makes the hard-break rule checkable at its source
• Self-sufficiency: src/markdown/portable/adf-to-portable-markdown.ts:288 reduceTaskList: the comment no longer prepares the reader for line 303
• Shape: src/markdown/portable/task-list.ts:12 splitTaskList: standing/stands reuse a word reduceStanding uses for another meaning

Maintainability senior, decided by:

• Locality: src/markdown/portable/task-list.ts:5 splitTaskList: the stay-or-stand rule lives once, where the reader's bulletNode and the writer's nestIn mirrored it
• Locality: src/markdown/parse/markdown-to-adf.ts:86 readBlocks: bulletNode returns a shape the caller quietly replaces, behind an unexplained block.kind guard
• Shape: src/markdown/portable/task-list.ts:9 splitTaskList: two cross-iteration accumulators, a negated compound ternary, near-synonym names, and heldTask hides the taskItem conversion
• Shape: src/markdown/portable/adf-to-portable-markdown.ts:303 reduceTaskList: one 180-character line maps the split and re-merges
• Shape: AGENTS.md:28 decision index: a title grew into a two-clause sentence

Junior A, decided by:

• Locality, Navigation: src/markdown/portable/task-list.ts:5 splitTaskList: one function decides for reader and writer, where each had its own rule
• Locality: src/markdown/parse/markdown-to-adf.ts:86 readBlocks: bulletNode returns an unfinished shape only the caller completes
• Locality: src/adf/inline-nodes.ts:3 InlineNodeModel.takesMarks: the hard break's rule lives in one row both directions read
• Shape: src/markdown/portable/task-list.ts:5 splitTaskList: a carried standing flag, a reassigned stands, and heldTask's name hides the conversion
• Navigation: src/markdown/parse/markdown-to-adf.ts:22 imports: both converters lead to the same named file

• Locality, Navigation: src/markdown/parse/markdown-to-adf.ts:98 listBreakFault: gone, with the base's look at blocks[index - 1] and blocks[index + 1] and the separator spelled in four places
• Navigation, Shape: src/markdown/parse/blocks.ts:232 continuesList: one named predicate on kind and delimiter that itemStart and openedList share

Inherited architect, decided by:

• Locality, Shape: src/markdown/parse/markdown-to-adf.ts:79 readBlocks: reads one block at a time, where the base judged a separator by its siblings
• Locality: src/markdown/emit/adf-to-markdown.ts:73 joinBlocks: a toggle carried across iterations sends a third adjacent list back to -, seen only by tracing
• Shape: src/markdown/emit/adf-to-markdown.ts:334 spelledList: the both-or-neither rule is one uncommented expression
• Self-sufficiency: src/markdown/emit/adf-to-markdown.ts:369 tryListItemLines: inner.startsWith('*') depends on the alternate bullet being *, and the comment needs the inline escaping worked out

Junior A, hardest first:

• Locality: src/markdown/parse/markdown-to-adf.ts:229 splitPath: replays splitTaskList's internals to name a path
• Self-sufficiency: src/markdown/emit/line-escaping.ts:189 escapeClosedRuns: the escaping rule lives in spec/flavour.md

Mid A, hardest first:

• Locality: src/markdown/emit/adf-to-markdown.ts:30 SpellingMemo: reference-keyed memo shared by parse and emit
• Self-sufficiency: src/markdown/parse/inline-content.ts:62 Scan: rules read with spec/flavour.md open alongside

Maintainability senior, hardest first:

• Locality: src/markdown/parse/markdown-to-adf.ts:257 directiveNode: the parser asks the emitter whether input was legal
• Self-sufficiency: src/markdown/emit/line-escaping.ts:189 escapeClosedRuns: needs spec/flavour.md Escaping open

Inherited architect, would restructure first:

• Navigation: src/markdown/portable/conventions.ts:23 flavourClaims: every flavour's switchboard sits in portable/
• Locality: src/markdown/emit/adf-to-markdown.ts:117 readableBlock: reader acceptance hangs on emitter verdicts
