Apply the AGENTS.md comments guideline to every .ts under tests/: remove
what the code already expresses, keep only what it cannot.
Removed: spec-header coverage inventories the describe/test tree already
names; comments restating the next line's assertion or its message; helper
JSDoc whose body already says it; within-file duplicates; five stale
claims (trendChart's "six aggregated turns" against agg.length === 8,
agentGraph's "six categories" against CATS' seven, fold-timing's "cheapest
call LAST" against a loop that feeds it first, fold-surface's unreachable
plain-JSON note, contextView's "two turns" for a one-turn fixture).
Kept and condensed: the projection-freeze class, strict wire/state-schema
hazards, retention and pricing windows, pairing rules, hostile-input
rationale, fixture and expectation-array ground truth, jsdom mechanics,
and issue-numbered regressions.
Comment lines 2604 -> 2014 (-22%); 85 module headers kept, 30 coverage
inventories dropped; every surviving comment line is within the 140-column
limit, with 36 wrapped lines joined onto fuller ones.
No logic, string, identifier, import or directive changed: a comment-strip
gate proves each file's comment-free code is byte-identical to HEAD, and a
line-level proof pairs all 845 changed lines with an unchanged code part.
pnpm run lint && pnpm run test (106 files / 2061 tests, per-file 100%
coverage) && pnpm run build all pass.
Merge consecutive short comment lines in tests/** up to the 140-col limit
without touching their text: comment-stripped content, comment text (whitespace
normalised) and line-comment runs are all proven identical per file. This is the
line-count half of the cleanup only; the content pass over tests/** is still
outstanding.
- compareVersions had zero production callers (the gate rides
meetsBaseline alone) and is not re-exported through the package entry;
its spec block duplicated what meetsBaseline's cases already pin
through compareParsed (a major-gap case joins meetsBaseline's block to
keep every arm covered). isNewerVersion keeps its own numeric-only
compare: ignoring prereleases there is the upgrade nudge's deliberate
semantics, and adopting the channel-aware order would change
user-visible behavior.
- pad2 hand-rolled padStart(2, '0') in a function that already used
padStart for the year.
- StoredHeaderTool/StoredHeaderRecord and DecodeCounts/DecodeSpans lost
export keywords nothing inside or outside the repo imported.
The supported set is now the two V4-generation lines (0.1.7-rc.2+ and
0.2.0-rc.2+): the manifest's dshReleases, the peer floors (>=0.1.7-rc.2,
cordis ^4.0.4 — both lines vendor 4.0.4), the devDependency pins, the
baseline matrix, the release workflow's tag fetch, and the compatibility
docs.
With every supported line on session format V4, the V3-only paths leave:
the fold reads the tool result's first-class message alone (source.callId
pairing, message.isError — the admission validation refuses any row whose
data.error outlives it); the settings.register host face module is gone
(the Config-form entry schema serves the preferences); the client drops
the settingsScope/settings.plugin.item card seat, the retired sessions.open
jump fallback, the legacy icon spellings, and the settings-dialog leg of
the settings jump; the history page's tool/result mapper reads the V4
message (its V3 wrapper reads were dropping result content on supported
lines); the cache probe rides the 2-arg cachedSnapshot face. The baseline
gate stays: a below-floor harness composes the fallback units and the
upgrade prompt, and an undetectable version still fails open.
Verified: pnpm run lint:fix && pnpm run test && pnpm run build green (1918
tests, 100% per-file coverage); the compat matrix passes against the real
dsh sources at both baseline tags; live on dsh 0.2.0-rc.2 the plugin
composes, the Plugins-page preference card renders and round-trips a
write, the insights warm-up fills the heatmap, and the session jump and
Context tab work end to end.
The supported range is now two baselines - dsh-v0.1.5-rc.1 (session
format V3) and dsh-v0.1.7-rc.2 (V4) - enforced by the runtime gate at
BASELINE_DSH_VERSION = 0.1.5-rc.1; below it the fallback units and the
upgrade modal take over (0.1.2/0.1.3 hosts were previously served by the
real folds).
The pre-V3 log shapes are dead code on every supported harness: the
running harness migrates historical logs on every read path (or refuses
the session wholesale), and 0.1.5-rc.1 rejects a request/header carrying
header.system outright. The fold therefore drops the V0/V2-only paths -
the header.system envelope system prompt, assistant/chunk floods,
{start, end} replacement endpoints, tool/code-dispatch - and the state
fields only they wrote (systemsFromHeader, the stepStart decode
accumulators). stateVersion stays 20: no supported log folds
differently, and pre-V3-era cached rows are discarded by the projection
cache's identity gate (and the strict stepStart sub-schema) instead of
served. The headers unit folds metadata-only epochs (envelope
systemTokens write dropped; the v1 cached-row read-compat and its pinned
stateVersion 1 stay); replaceRangeOf speaks startSeq/endSeq only; the
browser's epoch fetch maps request/header to tools and system/message to
the prompt text.
tests/baselines.ts re-fits to the two entries (the right Sidebar seam is
required on both), the compat matrix drives both tags' REAL sources
(canonical logs re-shaped to V3, the hostile probe renumbered past them),
and the version fixtures pin the new floor. Manifest: dshReleases
{0.1.5-rc.1, 0.1.7-rc.2}, dsh peers >=0.1.5-rc.1 (satisfies the 0.1.7
admission check under includePrerelease), devDeps pinned to the
0.1.5-rc.1 surface plus the ui-primitives runtime closure the client
lane inlines (test-only), and the release workflow fetches the two tags.
docs/compatibility.md is rewritten around the two-line matrix; README,
AGENTS.md and the issue template follow.
Also riding this move, from the audit pass: the fold re-proves an inject
source's form before it books the event record (the harness validates
`kind` but not `form` - a hostile one previously failed the strict
wire/state schemas on every delivery, the #44 freeze class), the headers
unit guards a data-less envelope (it has no try/catch of its own), the
schemastery schema annotations drop the explicit z<T> wrappers the 3.18.4
Mode generics reject, and the version-history note records why
stateVersion is deliberately not bumped.
At apply time the host probes the running harness's version (the
dshHomePath-anchored profiles mirror first, the plugin's module anchor
second) and compares it against BASELINE_DSH_VERSION 0.1.2-rc.1 — with
release > rc > beta > alpha ordering at equal X.Y.Z. A harness below the
baseline gets fallback projection units (both registry contract
generations) that fold nothing and serve zeroed data plus an
`unsupported` wire record; the client keeps rendering the blank cards
and pops a per-session-dismissable modal naming both versions and urging
the update. A detection failure or an unparseable version fails open, so
a probe misfire can never blank a working deployment.
