SUGGESTION: Avoid splitting Unicode surrogate pairs when truncating the title
String.slice counts UTF-16 code units, so a heading whose 119th code unit is the first half of an emoji produces a lone surrogate before the ellipsis. That malformed title will be escaped as \ud8xx in JSON and can render as a replacement character in the workspace UI. Truncate by code points (for example, with Array.from(text).slice(...)) and add a boundary test containing an emoji.

Strip closing ATX markers from title.
A valid heading such as # Release notes ### makes this regex return Release notes ###. The workspace UI then displays Markdown syntax in the record title. Remove a trailing closing hash sequence before truncation, and add a test for this form.

Memory blocks synced to the workspace arrived with no heading in the UI. A create runs the backend's LLM extractor, which writes its own `title` into the record's metadata. The repair `update` that follows restores the block verbatim, and it replaces the metadata dict wholesale — so the extractor's heading is written and then immediately dropped. `buildMetadata` never supplied one of its own, leaving every synced block title-less. `blockTitle` borrows the block's leading markdown heading, which blocks conventionally open with, and falls back to the block id when the content starts with body text. Long headings are capped at 120 characters. The archive path is unaffected: it spreads the record's existing metadata before overriding, so a title already stored survives.

Addresses review findings on the title derivation: - Read past a training block's metadata comment. Training blocks always open with `<!-- training ... -->`, so scanning raw content saw it as body text and fell back to the block id, costing exactly the blocks a title helps most. Reuses `stripTrainingMeta`, as `contentHash` already does. - Accept the up-to-three leading spaces CommonMark permits before the hashes. - Drop a closing run of hashes (`## Release notes ##`), which is decoration rather than title text. The run must be preceded by whitespace, so a heading ending in `C#` keeps its hash. - Truncate by code point. `slice` counts UTF-16 units, so a heading with an emoji on the 120-character boundary was cut mid-surrogate and rendered as a replacement character.

Thanks — all four findings were valid and are fixed in e7f6d64.
The training-block one was the most worth catching: those blocks always open with One finding I did not implement as suggested: a test asserting four leading spaces is an indented code block rather than a heading.

[WARNING]: Preserve indentation when stripping training metadata
stripTrainingMeta() ends with .trim(), so using it here removes all leading spaces from ordinary blocks before the CommonMark check. As a result, content such as # example (an indented code block, not an ATX heading) becomes # example and is published as the workspace title instead of falling back to the block ID. Strip only TRAINING_META_COMMENT for this scan, or otherwise avoid trimming indentation before matching, and add a four-space regression case.

Multi-model consensus review
Reviewed independently by 5 models (Claude, GPT-5.4 Codex, MiniMax M2.7, GLM-5.1, MiMo V2 Pro), converged over one round. No blocking issues — approving with a few suggestions inline and below.
The fix itself is correct: buildMetadata centralizes title computation and is called consistently on the create, repair-update, and plain-update paths, so the new title field survives the wholesale-metadata-replacement bug this PR describes. Test coverage of the blockTitle regex edge cases (indentation, closing hash runs, C#-style embedded hashes, training-block comment skipping, emoji truncation boundary) is thorough.
Additional minor issue (not inline — touches pre-existing code outside this diff)
archiveNow doesn't compute a title for legacy untitled records (memory-sync.ts:719-727, unchanged by this PR) — it builds metadata by spreading current.metadata rather than calling blockTitle, so a pre-PR record with no title archives without one. Consistent with this PR's stated scope; non-blocking. Worth noting: the archive code's own comment says "only this client filters the marker — other readers do not — so an archived record stays visible elsewhere," so an untitled archived record can still be visible, untitled, to other workspace readers — not fully without user-facing effect, just low-impact.
Missing tests
- No end-to-end test asserts the repair-update PATCH body actually contains
title— all new tests targetblockTitle/buildMetadatain isolation. The existing "a create is repaired with a verbatim update" test checksbody.metadata.block_idbut notbody.metadata.title, the one field this PR is about. - Boundary truncation at exactly 119/120/121 characters.
- A line with 7+ leading hashes (
####### heading) — not a valid CommonMark heading, should fall through toblock.id. - Content that is only a training-metadata comment with no heading after it.
- Windows line endings (
\r\n) —\s*$should consume the trailing\r, untested directly.
Positive observations
- Comments consistently explain why, not what — e.g. the surrogate-pair truncation rationale and the CommonMark closing-hash note.
- The fallback-to-id design (rather than borrowing the first body line) is the right call, and is explicitly justified both in code and in the PR description.
- Unicode-safe truncation via
Array.from(text)correctly avoids splitting surrogate pairs.

Nit (Code Quality): title?: string is optional here, but buildMetadata always populates it. Worth a one-line addition to the doc comment explaining the optionality is for backward compatibility with records written before this field existed (and for archiveNow, which spreads possibly-pre-PR metadata).

Minor (Design): This only recognizes ATX (#) headings, not Setext (===/----underlined) headings. A block whose first line is Deploy Steps followed by a line of === is valid CommonMark but falls straight to the block.id fallback here. Low-impact (worst case is the id fallback, not a wrong title), but worth a one-line comment scoping this to ATX intentionally so a future reader doesn't assume all heading forms are handled.

Minor (Logic Error): For a line like # ### or ## ##, CommonMark treats the trailing hash run as closing decoration on an empty heading (canonical example: # ## renders as <h1></h1>). The mandatory (\S.*?) capture here instead consumes those hashes as literal heading text, producing a title of "###" or "##" rather than falling back to block.id. Rare content shape, but a real deviation from the CommonMark handling the rest of this function is careful about.
Suggestion: after matching, check whether the captured text is itself only hashes/whitespace and treat that as no heading.

Minor (Design): contentHash (line ~449, unchanged by this PR) hashes content + tags + expires, not title. So an index entry written before this PR still matches on re-save, and push() returns "unchanged" before this line — and therefore blockTitle() — ever runs, for any block whose content/tags/expiry haven't changed since it was last synced. This matches the PR's Scope note ("Existing records keep their missing heading").
Worth confirming with the author: the "separate backfill call" mentioned in Scope would hit the same wall if it means today's backfill() — it calls the same partitionPending()/contentHash gate, so a plain re-run would also skip these records rather than fixing them.
#1353 (synced memory blocks get a title) merged to main between the beta and the release PR; the [0.12.2] entry now lists it. The changelog ships inside the binary, so it has to be in the tagged commit.

Summary
Memory blocks synced to the workspace arrive with no heading in the UI.
A create runs the backend's LLM extractor, which writes its own
titleinto therecord's metadata. The repair
updatethat follows restores the block verbatim,and it replaces the metadata dict wholesale — so the extractor's heading is
written and then immediately dropped.
buildMetadatanever supplied one of itsown, so every synced block ends up title-less.
memory-api.tsalready documents the extractor overwritingmemory_type/title;what was missing is that our own replacement never puts a title back.
Change
blockTitle(block)borrows the block's leading markdown heading — which blocksconventionally open with — and falls back to the block id when the content starts
with body text:
Falling back rather than borrowing the first body line avoids inventing a heading
the user never wrote. Headings are capped at 120 characters, since a block can run
to
MEMORY_MAX_BLOCK_SIZEand its first line can be most of that.The archive path is unaffected — it spreads the record's existing metadata before
overriding, so a stored title survives archiving.
Verification
memory-sync.test.ts, including 7 new ones covering headinglevels, leading blank lines, the body-text fallback, a bare
#hashtag, andtruncation.
test/memory/andtest/altimate/workspace/.tsgo --noEmitclean;oxlintreports no new warnings on the changed files.Scope
Existing records keep their missing heading — this fixes writes from here on. A
backfill would mean re-syncing each block, which is a separate call.

It now does viablockTitle, which borrows the block's leading markdown heading—skipping a training block's metadata comment—and falls back to the block id. Parsing follows CommonMark (leading spaces, decorative closing hash runs), and truncation counts code points so an emoji at the boundary is never split. Existing records keep their missing heading; only new writes are fixed. The archive path is unaffected since it preserves stored metadata.Written for commit e7f6d64.
