Vance IngallsandClaude Sonnet 4.6 740a83abb3 feat(core): hf-id write-back to disk + serve-time surfacing (R7, Tasks 1-2) (#1289)
* feat(core): clip-model hf- ids minted at parse, emitted as data-hf-id (R1)

* docs(core): document legacy-id round-trip in clip-model readback (R1 review)

Addresses Rames' review on #1270: clarifies that a pre-R1 clip authored with
id="my-title" round-trips as data-hf-id="my-title" (non-hf-shaped but stable,
exact-match) by design — targeting uses exact [data-hf-id="…"] match and does
not require the hf- shape; legacy values re-mint only at the R7 write-back. Not
a bug. Comment-only.

* docs(core): fix misleading legacy-id migration comment in htmlParser.ts

The original comment said legacy data-hf-id values "are re-minted only
once the R7 write-back persists freshly-minted ids to source" — which is
incorrect. ensureHfIds skips elements that already carry data-hf-id, so
legacy values (e.g. data-hf-id="my-title") persist indefinitely and are
NOT automatically re-minted. Exact-match targeting still works correctly.
Update comment to reflect actual behaviour.

* feat(studio): sourcePatcher data-hf-id targeting (R1, T3)

* fix(studio): warn on duplicate match in execDataAttrPattern (R1, T3 review)

Addresses Rames' review on #1271: execDataAttrPattern returned the first regex
match without checking for a second. A duplicate id/data-hf-id in source (id
drift) would silently patch one element and leave the other stale. Now warns
when more than one element matches. By the mint contract it should never fire.

* test(studio): pin hfId-is-authoritative-over-selector contract (R1, T3 review)

Adds test: "hfId match is authoritative — selector is not used as a
narrowing filter". When hfId matches element A and selector points at
element B, findTagByTarget returns A without consulting selector as a
narrowing filter. Pins the intended behaviour so a future refactor
cannot silently start narrowing by selector.

* feat(core): sourceMutation data-hf-id targeting (R1, T7)

* test(core): update htmlParser baselines for R1 hf- id format

Elements now get data-hf-id minted by ensureHfIds; parser reads
data-hf-id as model id, so HTML id attrs are no longer the model id.

* test(core): data-hf-id survives id/selector patch (R1, T7)

Locks the preservation guarantee the write-back design depends on: a
Studio edit targeting by id or selector (it never sends hfId) must not strip
an existing data-hf-id, or the stable handle is destroyed by the next edit.

* fix(core): escape hfId in selector + warn on duplicate match (R1, T7 review)

Addresses review on #1272 (Miguel P3 + Rames): findTargetElement interpolated
target.hfId raw into a [data-hf-id="..."] selector. Escape it (CSS attr-value
injection guard) and warn when a hfId matches more than one element instead of
silently patching an arbitrary one. Adds an injection-guard test.

* test(core): previewAdapter contract failing tests (T10 spec for R7)

* feat(core): hf-id write-back to disk + serve-time surfacing (R7, Task 1-2)

* test(core): replace tautological stability tests with real disk tests for persistHfIdsIfNeeded

Prior tests only exercised normalizeHfIds (pure function) and the existing
pin guard in ensureHfIds — both pass on the parent commit without any Task 1
code. Replace with three tests that exercise the actual disk write-back:

- writes data-hf-id to disk when source is untagged
- does not rewrite disk when source is already tagged (idempotent)
- returned id matches id written to disk (serve-time == persist-time invariant)

These fail on the parent commit (persistHfIdsIfNeeded doesn't exist) and
green after Task 1.

* test(core): route-level tests for data-hf-id surfacing and disk write-back (R7, Task 1-2)

Two integration tests against the preview route (via Hono test harness):

- served HTML carries data-hf-id on body elements (>= 2 matches for div+p)
- disk file contains data-hf-id after first GET (write-back verified via readFileSync)

These fail on the parent commit (no hfIdPersist wiring in preview.ts) and
green after Task 1. Closes the verification gap flagged in review.
