Reviewed rename pairing, validation, and archive refusal behavior and ran the focused 15-test suite locally. Malformed pairs now fail safely while valid consecutive pairs remain unchanged. Approved.
Resolve the conflict with Fission-AI#1800 and Fission-AI#1802 in requirement-blocks.ts: keep main's per-copy section reader and `[-*+]` bullet markers, and thread the unpaired-rename sink through every RENAMED header copy. A FROM left pending at the end of one copy is reported rather than paired with a TO in the next, and entries are sorted by line so the first reported is the first in the file.

…kers Cover the two shapes main gained after this branch was cut: a FROM in one `## RENAMED Requirements` copy and a TO in another are both reported as unpaired, and unpaired lines written with `*` or `+` are reported like `-` ones. Add a patch changeset matching the other parser fixes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Hardening pass pushed:
Re-verified the #1805 repro through the built CLI: main renames Invoice Generation's body to "Overdue Penalties" and exits 0; this branch reports both unpaired lines with line numbers and leaves the spec untouched. |

Unpaired RENAMED entries are detected with precise locations and fail before archive mutates specs, while valid pairs remain unchanged. Focused tests pass.
Closes #1805.
Why
parseRenamedPairswalked## RENAMED Requirementscarrying a single mutable{ from, to }and dropped whatever did not fit:FROM:overwrote an unpaired first oneTO:with no pendingFROM:was discardedFROM:was forgotten when the section endedNothing recorded any of it, and
validateChangeDeltaSpecsonly ever iteratesplan.renamed— the pairs that did form — so the validator structurally couldnot see the dropped lines. Two outcomes, both silent:
TO:written before itsFROM:yieldsno pair at all;
validatereports the change valid andarchiveexits 0having renamed nothing.
write a batch rename, listing the old names then the new ones — the second
FROMpairs with the firstTO. Archive renames a requirement the deltanever named, under a name the author wrote for a different one, and reports
→ 1as though exactly one intended rename occurred.Verified against a project built entirely by
openspec init+openspec new change: the body under the renamed header was the other requirement's body.What Changes
FROM:followed by aTO:with no secondFROM:betweenthem — the shape the documented format uses.
FROM:/TO:line that never formed a pair is recorded in a newDeltaPlan.unpairedRenamesentry (side,name, 1-basedline), sorted byline.
## RENAMED Requirementsis written more than once, pairs are still readper copy: a
FROM:left at the end of one copy is reported as unpaired, neverpaired with a
TO:in the next.validate <change>reports each one as an ERROR with its line number, sothe author learns at authoring time.
buildUpdatedSpecthrows on any unpaired entry, soarchiverefuses ratherthan applying a pairing it guessed. This is deliberate: with interleaved lines
the guessed pairing rewrites the wrong requirement, and a spec rewrite is not
something to do on a guess.
Well-formed renames are unaffected, including several consecutive pairs and the
no-bullet form.
Testing
test/core/parsers/renamed-pair-integrity.test.ts— 17 tests. Run againstmain: 15 failed / 2 passed (the passing two are well-formed-rename controls).All 17 pass on this branch.
Edge cases covered:
TO:beforeFROM:; aFROM:displaced by anotherFROM:; a trailingFROM:; fully interleaved FROM/FROM/TO/TOboth report nothing
buildUpdatedSpecstill applies a well-formed rename, and throws with theoffending line number for each malformed shape
validatereports the ERROR, and leaves a well-formed rename cleanFull suite green on this branch.
Changeset
.changeset/renamed-refuses-unpaired-entries.md(patch). Worth noting forrelease notes: this turns a previously silent mis-apply into a hard error, so a
change carrying a malformed RENAMED section that used to archive will now be
rejected until the pairing is fixed.
