xiongyuanwen-byted 7b58ba1b1d feat(sheets): batch-update contract hardening and style-vocabulary acceptance (#2028)
* feat(sheets): harden +batch-update sub-op contract (P0-1/2/3/5)

Eval-driven fixes for the top +batch-update error clusters (137 errors
across 7 eval batches, attribution in the optimization plan doc):

- Reject unknown sub-op input keys with did-you-mean + full key contract
  instead of silently ignoring them (silent ignore surfaced as misleading
  'missing required flag' errors — the largest cluster, ~35 hits).
  Habitual spellings are rewritten in place: camelCase -> snake_case,
  commandFlagAliases (new: size -> width/height on the resize pair, the
  pre-July vocabulary and the --styles protocol spelling, 15+ hits),
  single-entry ranges unwraps onto range.
- Aggregate per-op validation errors into one pass (each op's first
  error) instead of fail-fast first-error-only; single-error batches
  keep the standalone-shaped error (contract tests unchanged).
- Precheck cells matrix vs range locally: empty cells (prescribes
  +cells-clear) and row/column count mismatches no longer reach the
  server mid-batch.
- Correct the atomicity story: execution is fail-fast without rollback
  (verified against live batches; docs promised a rollback that does
  not happen). Partial-failure errors now spell out that succeeded
  operations stay applied and prescribe resending only the failed
  tail, preventing double-apply on retry.

* feat(cli): accept @file payload reads from the system temp dir (P0-6)

Agents stage generated payloads (batch operations JSON, CSV) in /tmp as
a matter of course; the relative-to-cwd-only policy pushed every
--operations @/tmp/ops.json through an extra python/stdin round trip
(recurring friction cluster in eval traces).

Scope is deliberately narrow: a new SafeTempAbsInputPath accepts an
absolute READ path only when it resolves (symlinks included) under the
canonical os.TempDir(), and only the @file expansion in
cmdutil.ReadInputFile uses it. SafeInputPath stays strict — uploads,
drive sync and the CI quality gates treat 'absolute paths rejected' as
a load-bearing invariant. Absolute paths outside the temp dir now get
a prescriptive error naming all three options (relative path, temp-dir
path, stdin).

* feat(sheets): add +styles-put, +dim-delete --ranges, freeze in --styles

Batch-B of the +batch-update overhaul (attribution: ~73% of real batch
calls were pure formatting finishers hand-built as operations arrays).

- +styles-put: declarative visual spec for existing spreadsheets.
  Reuses the workbook-create/table-put --styles parser (identical
  vocabulary and aggregate-all-issues errors), expands client-side into
  ONE atomic batch_update per spec: cell_merges -> cell_styles ->
  row_sizes -> col_sizes -> freeze. Style stamps are safe to re-run.
  Verified live: 6/6 sub-ops applied, frozen rows / merges / row
  heights confirmed by read-back.
- freeze section added to the shared --styles pipeline ({rows, cols}),
  so +workbook-create and +table-put gain it too — closes the one gap
  that still forced a separate +dim-freeze call.
- +dim-delete --ranges: scattered row/column ranges in one atomic
  batch, ordered DESCENDING so earlier deletions never shift later
  indexes (the recurring failure of hand-built dim-delete batches);
  same-dimension and non-overlap enforced, nesting inside
  +batch-update rejected with a prescription.
- +cells-batch-set-style enters phase-1 deprecation: kept working,
  docs point at +styles-put, an in-band note steers new usage.

Skill docs regenerated from sheet-skill-spec (new
lark-sheets-styles-put reference, three-way dispatch in guideline 6,
fail-fast-no-rollback wording).

* feat(sheets): accept height/width as one-way aliases for size in --styles row/col_sizes

size stays the canonical dimension key: it keeps row_sizes and col_sizes
items shape-uniform (the array name already carries the dimension), it is
what shipped with workbook-create/table-put and what models demonstrably
converge on, and it matches the dimension-neutral precedent of comparable
APIs. The Excel-vocabulary words are accepted silently only where
unambiguous — height inside row_sizes, width inside col_sizes; the wrong
dimension's word gets a targeted error instead of a rewrite, and giving
both size and the alias is rejected. Shared parser, so +workbook-create /
+table-put / +styles-put all gain it.

* chore(sheets): sync skill docs — +cells-batch-set-style fully exits the skill surface

Regenerated from sheet-skill-spec: the deprecated command no longer
appears anywhere in SKILL.md or the references (multi-range styling
routes to +styles-put); its flag-defs entry is untouched, so the command
and --help keep working for compatibility callers, with the in-band
supersedence note steering them to +styles-put.

* fix(sheets): forgive habitual vocabulary on the --styles payload path

07-20 rerun attribution: the batch-update dispatch worked (calls 105->25,
errors 21->8; +styles-put adopted by 16/35 tasks) but +styles-put itself
hit a 56% stateful error rate — the redesign moved traffic from the flag
path onto the payload path, and the round-2 forgiveness layers (key
aliases, enum-value canonicalization) only existed on the flag path.
Both dominant clusters are fixed in the shared styles pipeline, so
+styles-put / +table-put / +workbook-create / typed --cells all gain it:

- border family folding (largest cluster, up to 88 issues in one retry):
  borders/border objects, border_top..right objects, border_style/color/
  weight scalars, and flattened border_<side>_<attr> keys all fold into
  the canonical nested border_styles; border_style:"thin" reads as a
  thin solid line (weight vocabulary in the style slot).
- enum VALUE canonicalization inside cell_styles (~10 server-side
  round trips: vertical_alignment "center" -> "middle"), sourced from
  the +cells-set-style flag enums; off-enum values now fail client-side
  with a did-you-mean instead of failing the whole batch server-side.
- wrap family: wrap_text/text_wrap -> word_wrap, boolean -> enum.
- bare-string cell_merges entries read as {range, merge_type:all}.
- fore_color gets a prescription (openpyxl fgColor is the FILL color;
  a silent pick could color the wrong thing).

Replayed the eval-failing payload shapes live: 2/2 applied.

* feat(sheets): resize type optional in --styles; acceptance-surface contract tests

- {range, size} in row/col_sizes now means a pixel resize (type stays
  for standard/auto) — the payload path matches the flag path, where
  --width never required --type.
- Two closure tests turn the --styles acceptance surface into a locked
  contract instead of open-ended patching:
  * vocabulary parity — every +cells-set-style flag (iterated from
    flag-defs) must be accepted verbatim by the payload path, so a
    future flag can never again ship without payload-path support;
  * prior corpus — every model spelling observed across the 07-08..07-20
    eval batches must either normalize to canonical or produce a
    targeted prescription; silent ignoring and bare rejection both fail
    the suite. New eval finding -> add a corpus row -> fix -> locked.

Skill docs regenerated: the border shorthand ({style,weight,color} on
all four sides) is now the teaching form, border_styles demoted to
per-side differences; resize examples drop the type ceremony.

* fix(sheets): close the 07-21 rerun residuals — full-form thin, range coalescing, typed-cells style key

Valid rerun (skill injection verified at ~31k chars/task): +styles-put
stateful error rate fell 56.5% -> 34.3% and batch-update stayed at its
post-dispatch low. Three residual clusters, all closed:

- weight vocabulary in the FULL nested form's style slot
  (border_styles.<side>.style:"thin" — 8 tasks, the dominant residual;
  the earlier rewrite only covered the shorthand scalar path). Now
  normalized in expandBorderAllShorthand, the single border touchpoint
  shared by the flag, typed-cells and styles-payload paths.
- per-row specs blowing the 100-op cap (184/203/861-op expansions):
  coalesceStyleStamps fuses identical-style entries into rectangles
  (vertical fixpoint merge on same column span, horizontal on same row
  span) before the cap — a declarative spec describes intent, execution
  shape is the CLI's to optimize. Cap message now also routes
  alternating-row banding to +cond-format-create.
- typed --cells habitual keys (recurring server-side 900015206 in both
  reruns): cells[][].style object rewrites to cell_styles;
  cells[][].type gets a prescription instead of a server round trip.
  The content-in-styles message is also neutral now (was
  workbook-create-specific).

Corpus + coalescing + typed-cells tests added; live replay: full-form
thin accepted and 3 same-style rows fused, all applied.

* refactor(sheets): give the style-vocabulary acceptance layer its own home

Pure mechanical move, zero behavior change (locked by the acceptance
contract tests). The acceptance layer had grown as an accretion across
helpers.go and lark_sheet_workbook.go — deliberate design (one canonical
form + wide acceptance, per the divergent-priors evidence), accidental
placement.

style_vocab.go now holds the whole subsystem — flag-path style builders,
key aliases, enum-value canonicalization, border folding/normalization,
typed-cells cell-object rewrites — under a header that states the design
contract: rewrites must be unambiguous, ambiguity prescribes, silence
and bare rejection are both bugs, closure is enforced by the parity +
prior-corpus tests. helpers.go shrinks back to generic plumbing
(818 -> 542 lines).

The other two acceptance surfaces keep their own homes: cobra flag
ergonomics in flag_ergonomics.go, batch sub-op key vocabulary in
batch_op_dispatch.go.

* fix(sheets): enforce the cells-vs-range match on single-cell ranges too

The precheck deliberately skipped bare single-cell ranges when server
behavior was unverified; the 07-21 rerun supplied the evidence (12 rows
against range "A1" failing server-side with row count 1) — +cells-set
has no anchor semantics, the strict match applies everywhere. Corpus
updated accordingly.

* feat(sheets): make +csv-get --range optional — omitted reads the whole sheet

The tool requires a range but clips past-grid references and reports the
clip in actual_range, so the CLI sends an over-wide whole-columns range
(A:ZZZ) when --range is omitted: one call reads the entire sheet, no
workbook-info pre-flight to size it first. Eval evidence: 'required
flag(s) range not set' was the most-missed required flag on +csv-get
(4 tasks in the 07-21 batch) — the models' intent was always 'read it
all'. Blank --range now means the same as omitting it.

Skill docs updated (quick-reference row, read-data full-read example,
flag desc); round-3 backlog item A5.

* feat(sheets): add editing rule #10 — never fabricate missing values

补齐 / 扩展 / 按原表格式续填时,查不到或无法确定的值一律留空 +
备注注明,禁止用推算 / 估算 / 凭空数据充数;原表已示范缺失值写法时照抄。

Synced from sheet-skill-spec (SoT).

* fix(sheets): accept side-first border word order and wrap_strategy

07-21 evening batch (first run carrying the previous fixes — thin
full-form / style/type keys / csv-get range all at zero): the corpus
loop caught the next spelling permutations. bottom_border /
bottom_border_style (side-first word order, alongside the border_bottom
family already folded) and wrap_strategy (the Google Sheets API word)
now normalize; three corpus rows lock them.

* feat(sheets): universal did-you-mean on unknown style fields; formalize the silent-alias admission bar

The alias table was drifting toward per-permutation entries with fast-
falling marginal value (first aliases covered 15+ errors each, the last
ones 1-2). The asymmetry that matters: rejection is universal, aliases
are per-word. So:

- unknown style fields now reject with did-you-mean + the full canonical
  field list (this error had neither — the actual reason word-order
  permutations turned into multi-issue retry loops). Any future
  permutation costs one self-healing retry, zero new code, and corrects
  the whole session (silent aliases never correct the model in-session).
- the acceptance-layer contract now states the admission bar for silent
  aliases: real external vocabularies only (Excel/openpyxl, CSS, Google
  Sheets API — a finite set), recurring across batches or ≥3 tasks,
  zero ambiguity. Permutations go to the universal rejection. Existing
  permutation aliases are grandfathered.

* feat(sheets): +cells-set --writes — scattered multi-region writes in one atomic call

The last compressible batch-update scenario: eval traces show 'fix all
broken formulas across ranges/sheets' (~6 calls / 3 tasks per batch)
still hand-assembled as +batch-update operations arrays. --writes takes
[{sheet_name|sheet_id, range, cells}, ...] (up to 100 items, cross-sheet)
and fans it into ONE atomic batch_update of set_cell_range ops.

Design decisions:
- the sheet selector LIVES IN EACH ITEM — no top-level fallback, no
  precedence table; same convention models already learned from
  +batch-update sub-ops and +styles-put items. A top-level
  --sheet-name/--sheet-id with --writes is rejected with the fix.
- every item runs the exact standalone pipeline via a per-item flag
  view: key vocabulary (camelCase, aliases, did-you-mean), the style
  acceptance layer for inline cell_styles, matrix precheck, schema
  validation; item errors aggregate so one retry fixes all.
- XOR with --range/--cells/--copy-to-range; top-level --allow-overwrite
  propagates to items that don't override it.
- nesting inside +batch-update rejected (expands into its own batch).
- predictable prior handled: --styles on +cells-set now hints the
  layering (range-level styling -> +styles-put; per-cell styles ride in
  the cells objects) instead of a bare unknown-flag error.

Live smoke: value + formula regions in one call, 2/2 applied.
Expected effect: batch-update calls drop another ~30% to its
heterogeneous-atomic-chain steady state.

* chore(sheets): bump lark-sheets skill version to 3.1.0

Version roll-up for the batch-update optimization series: cells-set
--writes, universal did-you-mean on style fields, border word-order and
wrap_strategy acceptance, editing rule #10, and optional +csv-get
--range.
