Why

A trace analysis over 14,818 lark-cli sheets calls attributed 2,036 command errors to 57 (subcommand, flag) groups; the top 6 cover 76%. This PR addresses the four that are ours to fix, each at the layer that produced it.

Reproduced every group against main first — several were already prescribed correctly and are left alone; what follows is only what still failed.

What changed

--styles vocabulary — 291 cases, the only group whose retry also failed

  • One shared prescription for the border family. foldBorderFamilyAliases already absorbs border / borders / border_<side> / border_<attr>. What still reached the error path was the Lark OpenAPI's border_type (FULL_BORDER / OUTER_BORDER) and CSS's border_width — real vocabularies with no equivalent here, and border_type was the single top field in the group. Neither maps unambiguously onto a per-side style/weight/color triple (FULL vs OUTER differ on interior edges this payload cannot address), so they get a prescription, not a silent alias.
  • Prescribe the nested {range, style:{…}} envelope — the OpenAPI's own request shape, copied one level too deep — plus bg_color / fill_color / text_color.
  • Prescriptions match on the key's letters alone, so border_type, borderType and border-type are one mistake rather than three.
  • Collapse repeated issues in the --styles / --writes folds. One wrong field name in a payload styling N cells produced N identical issues, each re-listing the full supported vocabulary — the fold meant to save round trips was burying its own answer. Six same-field cells went from 1,646 characters of repetition to one statement plus the other locations:
--styles has 7 issues (2 distinct): …cell_styles[0].border_type … [same at 5 more: …cell_styles[1].border_type, …[2], …[3], +2 more] | …cell_styles[6].bold …

--sheets payload — 419 cases

  • Accept dtypes / formats as a positional array. The same pandas habit that produces columns and data produces df.dtypes.tolist(); the payloads were otherwise correct and every retry just rewrote the same information as a map. Only a 1:1 match with columns is accepted — a length mismatch is rejected with the alignment rule, never guessed. The map form and the unknown-column check are unchanged, and the canonical form stays the map (wide acceptance layer, one documented shape).

+csv-put --file — 35 cases

  • Read the value as a path. --file is aliased onto --csv because agents reach for it, but the two names promise different things: rewriting only the name left the path to be written into the sheet as literal text, which the file-path guard then rejected — an error naming a flag the caller never typed. The read goes through the same cmdutil.ReadInputFile as @file, so the relative-path policy is identical (an absolute path is still rejected, toward stdin). A value naming nothing readable falls through untouched, so --file holding literal CSV keeps working.

--help — 88 cases of required flag(s) "title" not set

  • Mark required flags in the sheets help. MarkFlagRequired only sets a completion annotation cobra never renders, so --title was listed exactly like an optional flag. Scoped to this domain (rides the existing withFlagErgonomics PostMount chain); no other domain's help shifts. Sourced from flag-defs rather than the cobra annotation, because +chart-create and +csv-put deliberately clear it after mounting while the flag stays required on the real path — and a flag cobra has since put in a one-required group is left unmarked, since neither member of such a pair is individually required.
+workbook-create   --title      (required) Spreadsheet title
+chart-create      --properties (required) Full chart config JSON…      # relaxed annotation, still required
+csv-put           --csv        (required) RFC 4180 CSV text…
+csv-put           --start-cell Top-left A1 anchor…                     # one-required pair with --range, unmarked

Not in scope

The largest single group — absolute paths passed to --file / @file (636 cases) — is deliberately untouched. The cwd-relative policy is a protocol decision (PR #2091), and that thread is being followed up separately.

Testing

  • New: 7 rows in stylesPriorCorpus, 4 collapse-fold unit cases, 4 positional-dtypes cases, 5 --file path cases, 4 required-help cases. One existing assertion was rewritten into two (distinct defects each render; identical defects collapse).
  • go vet ./..., gofmt, go test ./shortcuts/... ./cmd/... clean; lint/ source-contract scan byte-identical to main; make quality-gate passes.
  • Pre-existing failures on main, unrelated and unchanged: tests/cli_e2e/base TestBase_BasicWorkflow, and the sheets e2e suite (the locally built binary's app lacks drive:drive / space:folder:create).

Summary by CodeRabbit

  • New Features

    • Help output now marks genuinely required flags with “(required)”.
    • --file can load CSV content from a readable file path.
    • Sheet data types and formats support positional arrays aligned with columns.
    • Added clearer guidance for common style-field and border-related names.
  • Bug Fixes

    • Validation errors now consolidate repeated issues while preserving useful locations and counts.
    • Invalid column definitions and mismatched positional data produce clearer alignment errors.
    • CSV input now preserves intended behavior when switching between --file and --csv.

…val batch

A trace analysis over 14,818 `lark-cli sheets` calls attributed 2,036 command
errors to 57 (subcommand, flag) groups, with the top 6 covering 76%. Four of
them are ours to fix; each is addressed at the layer that produced it.

--styles vocabulary (291 cases, the only group whose retry also failed):

  - Prescribe the border family as a whole. foldBorderFamilyAliases already
    absorbs border / borders / border_<side> / border_<attr>; what still
    reached the error path was the Lark OpenAPI's border_type (FULL_BORDER,
    OUTER_BORDER) and CSS's border_width — real vocabularies with no
    equivalent here, and border_type was the single top field in the group.
    Neither maps unambiguously onto a per-side style/weight/color triple, so
    they get one shared answer, not a silent alias.
  - Prescribe the OpenAPI's nested {range, style:{...}} envelope, plus
    bg_color / fill_color / text_color.
  - Match prescriptions on the key's letters alone, so border_type,
    borderType and border-type are one mistake, not three.
  - Collapse repeated issues in the --styles / --writes folds. One wrong
    field name in a payload styling N cells produced N identical issues, each
    re-listing the full supported vocabulary: the fold meant to save round
    trips was burying its own answer. The defect is now stated once and the
    other locations are named.

--sheets payload (419 cases):

  - Accept dtypes / formats as a positional array. The same pandas habit that
    produces `columns` and `data` produces df.dtypes.tolist(), and the
    payloads were otherwise correct. Only a 1:1 match with `columns` is
    accepted; a length mismatch is rejected rather than guessed.

+csv-put --file (35 cases):

  - Read the value as a path. --file is aliased onto --csv because agents
    reach for it, but the names promise different things — rewriting only the
    name left the path to be written into the sheet as literal text, which the
    file-path guard then rejected, with an error naming a flag the caller
    never typed. The read goes through the same cmdutil.ReadInputFile as
    @file, so the relative-path policy is unchanged and stdin stays the
    out-of-tree route. A value naming nothing readable still falls through to
    the guard, so --file holding literal CSV keeps working.

--help (88 cases of "required flag(s) ... not set"):

  - Mark required flags in the sheets help. MarkFlagRequired only sets a
    completion annotation cobra never renders, so a required flag read exactly
    like an optional one. Sourced from flag-defs, since +chart-create and
    +csv-put deliberately clear that annotation after mounting; a flag cobra
    has put in a one-required group is left unmarked, because neither member
    of such a pair is individually required.

The remaining big group (absolute paths passed to --file / @file, 636 cases)
is deliberately untouched: the cwd-relative policy is a protocol decision, and
that thread is being followed up separately.

📝 Walkthrough

Walkthrough

The change adds CSV file-alias provenance and resolution, required-flag help markers, positional dtype and format inputs, repeated validation issue collapsing, and targeted style-field prescriptions.

Changes

Input ergonomics

Layer / File(s) Summary
Flag provenance and required help
shortcuts/sheets/flag_ergonomics.go, shortcuts/sheets/flag_ergonomics_test.go
Flag normalization records the alias used for a canonical flag. Mounted help marks applicable required flags.
CSV file alias resolution
shortcuts/common/runner.go, shortcuts/sheets/lark_sheet_write_cells.go, shortcuts/sheets/csv_put_guard_test.go
+csv-put reads paths supplied through --file, marks file contents as source-resolved, and preserves inline or already-resolved values.

Validation messages

Layer / File(s) Summary
Repeated validation issue rendering
shortcuts/sheets/helpers.go, shortcuts/sheets/helpers_test.go, shortcuts/sheets/lark_sheet_write_cells.go, shortcuts/sheets/lark_sheet_workbook.go, shortcuts/sheets/styles_prescription_test.go
Repeated indexed validation issues collapse into distinct messages with repeated locations and distinct counts.
Style field prescription lookup
shortcuts/sheets/style_vocab.go, shortcuts/sheets/lark_sheet_workbook.go, shortcuts/sheets/styles_acceptance_test.go
Style validation adds targeted prescriptions for border, color, nested-style, and separator-variant field names.

Table column label input

Layer / File(s) Summary
Column label decoding and normalization
shortcuts/sheets/lark_sheet_table_io.go
dtypes and formats accept maps or positional arrays. Arrays align with columns, and resolved values drive normalization and validation.
Column label validation coverage
shortcuts/sheets/lark_sheet_table_io_test.go
Tests cover positional arrays, length mismatches, map compatibility, unknown columns, and format overrides.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to cbe3a

The PR improves Sheets input guidance, payload compatibility, CSV file handling, and required-flag help. A bounded risk remains that reused command instances may carry an earlier local-file value into a later recovery flow, and one validation hint omits the newly supported positional label form; the change is mergeable with explicit owner awareness or follow-up.

374-375: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the expected-shape hint.

Line 374 says that dtypes and formats must be column-name-keyed maps. Positional arrays are now valid when they align 1:1 with columns. If another field fails to decode, this hint can tell the caller to rewrite a valid array unnecessarily.

Proposed fix
- "expected shape: %s (columns is a flat string array; dtypes/formats are column-name-keyed maps; data is row-major)",
+ "expected shape: %s (columns is a flat string array; dtypes/formats are name-keyed maps or arrays aligned 1:1 with columns; data is row-major)",

Two defects in the +csv-put --file rule from the previous commit, both found
in review:

- The alias record was written from the flag-name normalizer, which pflag also
  runs for Lookup and Set — including once with the canonical name right after
  the rewrite, and again on every later lookup. `--file a.csv --csv ./b.csv`
  therefore still counted as "supplied by --file", and an explicit --csv path
  was silently read as a file instead of meeting its guard. The spelling is now
  staged by the normalizer and committed by the flag's Value, which runs once
  per real occurrence, so the last occurrence wins in either order.

- The rewritten value was not marked as read from a source, so a file whose
  contents are themselves path-shaped ("report.csv") failed csvPutInput's shape
  check — a valid CSV rejected as a caller who forgot the @. Marking it makes
  --file behave exactly like --csv @<path> all the way down, which also lets
  the guard skip it on its own rather than through a special case in Validate.

RuntimeContext gains an exported MarkInputResolved for the second half: the bit
already existed for @file / stdin, and a domain that resolves a source itself
needs to set it. No other domain calls it, so nothing else changes.

Also assert the typed contract (Param, Cause) rather than message text alone in
the style-prescription corpus and the collapsed-issue fold, per the repo's
error-test guideline.

Thanks — verified all four findings against the code before acting; two were real bugs, both now fixed in 224a416.

1. Alias provenance not cleared by a later canonical occurrence — valid, fixed.

Reproduced: --file a.csv --csv ./second.csv silently read second.csv as a path, where a bare --csv ./second.csv correctly errors.

The suggested fix (clear the record on a canonical occurrence) does not work as stated, though: pflag runs the normalizer for Lookup and Set too — once with the canonical name immediately after the rewrite, and again on every later lookup, including the framework's own resolveInputFlags before Validate. Clearing there would wipe a legitimate --file attribution on a plain --file x.csv call.

Fixed by moving the commit point off the normalizer: it now only stages the spelling, and the flag's pflag.Value commits it on Set, which runs exactly once per real occurrence. Last occurrence wins in either order. Same shape as flagalias.Bind's own pendingSource/commit, which this can't reuse because Bind advertises its aliases on the flag and in the exported manifest while these rewrites are deliberately silent. Regression tests cover both orders plus --file alone.

2. Rewritten value not marked source-resolved — valid, fixed.

Reproduced: a file containing report.csv was read correctly and then rejected by csvPutInput's shape check. RuntimeContext.MarkInputResolved is now exported (the bit already existed for @file / stdin; a domain that resolves a source itself needs to set it) and resolveCSVPathFromFileAlias sets it. --file <path> is now equivalent to --csv @<path> all the way down, which also removed the special case that was skipping the guard from Validate. Regression test added for path-shaped contents.

3. Typed-error assertions — valid, applied.

Both sites now assert Param and a non-nil Cause alongside the message, including the shared prescription-corpus runner that covers the seven new rows.

4. Expected-shape hint still says maps only — acknowledged, not changing.

Deliberate. style_vocab.go states the domain contract this file follows: one canonical form is documented, the acceptance layer beneath it is wide and undocumented. The hint is a repair instruction, and the map form it prescribes is always correct — including for a caller who already wrote a valid positional array. Advertising the array form would make the wide layer part of the contract, which is what that rule exists to prevent.

…age alias provenance only while parsing

Both from self-review of the branch.

An unreadable path passed as --file fell through to the --csv guard, which
answered naming a flag the caller never typed — and for a file that exists but
cannot be opened, prescribed "pass the same path with an @ prefix", which routes
through this very reader and fails identically. Only one case may fall through
now: a value that names nothing AND is not path-shaped, i.e. literal CSV text,
which --file accepted before this rule existed. A path-shaped value naming
nothing, an unreadable file, and a directory each answer under --file.

The alias spelling was staged with no Parsed() guard (the first commit had one;
flagalias.Bind still does). chainFlagAliases looks its aliases up while
installing and pflag normalizes on Lookup, so composing PostMount twice — which
installAliasProvenance explicitly anticipates — replayed "file" through the
already-installed normalizer at mount time, and the next real --csv occurrence
committed it: an explicit --csv path would then be read from disk instead of
meeting its guard. Verified the new regression test fails without the guard.

Self-review of the full branch turned up two more defects in the --file rule, both fixed in 962f206.

1. An unreadable --file path was answered under --csv.

The fall-through kept only the "value names nothing" case in mind, but it also caught paths that name something unreadable. Reproduced through the mounted shortcut:

  • --file ./typo.csv--csv value "./typo.csv" looks like a file path…, Param --csv, hint offering --csv @<path> — the wrong flag named.
  • --file ./noread.csv (mode 0000) → …is an existing file… pass the same path with an @ prefix, which cannot work: @file routes through this same reader and fails identically.

Now exactly one case falls through: a value that names nothing and is not path-shaped, i.e. literal CSV text, which --file accepted before this rule existed. Everything else answers under --file:

input answer
absolute / out of tree --file … must be a relative path + stdin
path-shaped, names nothing --file "…" names no file under the current directory
exists, unreadable / a directory --file cannot read file "…" (hint points at stdin, not @)
literal CSV text passes through to the --csv guard, unchanged

2. The alias spelling was staged with no Parsed() guard.

The first commit had one; I dropped it when moving the commit point to the flag's Value, on the reasoning that Value.Set is the only committer. But staging still happens in the normalizer, and chainFlagAliases looks its own aliases up while installing — so with PostMount composed twice (which installAliasProvenance explicitly anticipates and handles), Lookup("file") replays through the already-installed normalizer at mount time and arms pending; the next real --csv ./data.csv occurrence then commits it and the value gets read from disk instead of meeting its guard.

Restored the guard. Confirmed the new double-mount regression test fails without it (expected error, got nil) and passes with it.

go vet / gofmt / go test ./shortcuts/... ./cmd/... ./internal/... clean; lint/ contract scan byte-identical to main; make quality-gate passes.

…y --file read error

Second review pass, both valid.

FlagSet.Parsed() stays true once parsing has started, so the guard added in the
last commit only covers a remount that happens BEFORE the first parse. A remount
afterwards — its own alias lookups running through the normalizer the first pass
installed — could still leave a spelling staged for the next occurrence to
commit, which would read an explicit --csv path from disk. Re-running the
install now resets staging, closing the window from the other side. Verified the
new parse/remount/reparse test fails without the reset.

The unreadable-file and directory branches preserve the read error as Cause;
their tests now assert it, matching the sibling that already did.

Second review pass — both valid, fixed in cbe3a8f.

Clear alias staging independently of Parsed() — correct, and it reproduces.

Parsed() stays true once parsing has started, so my guard only covered a remount that happens before the first parse. Wrote the parse → remount → reparse test you asked for and it fails on the previous commit exactly as described: an explicit --csv ./data.csv is read from disk instead of meeting its guard.

Closed it from the other side rather than by dropping Parsed(): re-running installAliasProvenance (which every remount does) now resets staging, so a spelling staged by a remount's own alias lookups cannot survive into the next occurrence. Parsed() stays as the pre-parse half of the same invariant — together they cover both orders, and each half now has a test that fails without it.

Assert Cause on the unreadable-file and directory branches — applied; they now match the sibling subtest that already asserted it.


On CI: the e2e-live failure on the previous head is tests/cli_e2e/base TestBase_RoleWorkflow+role-create succeeds, then the role is missing from +role-list, so every later subtest fails on an empty role ID. That is the live Base tenant, not this branch: the only file outside shortcuts/sheets/** in this PR is a rename of RuntimeContext.markInputResolved to MarkInputResolved plus its three call sites (git diff main...HEAD -- shortcuts/common/ is 12 lines, all mechanical), which no Base command reaches. results is the aggregate job and follows e2e-live. Watching the run on the new head.

CI is green on cbe3a8f4run 33295498157, e2e-live included.

That settles the earlier e2e-live red: tests/cli_e2e/base TestBase_RoleWorkflow is flaky against the live tenant, not a regression here. Two things confirm it — the same suite passed on #2558 at 08:57 the same day, and in the failing log +role-list returned only the three template defaults (Editor / 普通用户 / Reader, total: 3) with byte-identical role_ids across independent re-runs, i.e. the listing was not seeing the base the role had just been created in. Worth a look from the Base side, but nothing this branch touches.

The one remaining red check in the rollup is the results job of run 33295421461, which was cancelled mid-flight by the concurrency group when the current run superseded it; the same check on the live run is green.

Merging main brought #2559's tests for the --file → --csv alias, written
against the policy this branch replaces. Two of them fail on it, both because
the verdict they describe moved rather than disappeared.

The out-of-tree case used /tmp, which the allowlist now accepts, so the value
came back as a missing file instead of an out-of-tree one; it now names a path
no allow root can contain. The directory case is refused when the descriptor
is inspected, before a read is attempted, so the message reads "not a regular
file". What the caller sees of both — the flag named, the cause kept, stdin
offered — is unchanged.

That message listed the kinds it refuses and omitted directories, which is how
it reached a directory test reading as a mismatch. It now names them.

* feat(vfs): allow absolute paths under a built-in path allowlist

Path flags only accepted paths relative to the working directory, so an
agent passing a full path (typically under /tmp) failed on its first call
and had to retry with a relative one.

Absolute paths are now accepted when they resolve inside a built-in
allowlist: the working directory, /tmp, and ~/files. A built-in denylist
covers system and credential locations and wins over the allowlist,
including over the working directory. Both lists are compiled in and read
no environment variable, flag, or config file, so the effective policy is
fixed by the binary; upgrading is all it takes for the new behavior to
apply.

Containment is decided by file identity (device and inode) alongside the
resolved name, because a single directory has many spellings: APFS folds
U+017F onto "s", so ".sshh" spelled with it opens ~/.ssh, and NTFS and
APFS both compare case-insensitively.

Reads are hardened where the policy applies: O_NOFOLLOW pins the final
component, O_NONBLOCK keeps a FIFO from blocking before it can be
refused, and the opened descriptor is matched against the inspected
object, rejected when it is not a regular file, and rejected when it
carries extra hard links. The relaxed local-input tier used by apps
upload keeps its own contract (symlinks are legitimate arguments there)
and gains the denylist check instead.

Two behaviors are deliberate rather than incidental. Working inside a
denylisted directory now refuses even relative paths, since the denylist
is unconditional. Running as root leaves only the working directory and
/tmp, because the home directory is then /root, itself a deny root.

Existing tests asserted the old "every absolute path is refused"
baseline; they now assert the allowlist. Traversal fixtures escape to the
filesystem root, which stays outside every allowed root on Linux, where
the temp directory that hosts t.TempDir() is /tmp itself.

* fix(vfs): close two paths around the built-in denylist

A "~/..." argument had two readings: validation expanded it to the home
directory, while a caller that keeps the original string — SafeLocalFlagPath
returns it verbatim — opens whatever "~" names in the working directory. A
symlink there carried reads past the denylist, confirmed by reading
/etc/passwd through it. Every interpretation of an argument is now checked,
so the shorthand still reaches ~/files while the literal entry cannot
escape.

With no LARKSUITE_CLI_CONFIG_DIR and no reachable home directory,
core.GetBaseConfigDir keeps credentials in a bare ".lark-cli" resolved
against the working directory, which is an allow root. That fallback is now
mirrored as a deny root, so containers whose home lookup fails do not expose
their stored tokens.

* fix(vfs): enforce hard-link checks across readers

* fix(vfs): stop an output hard link from rewriting a file outside the allowlist

A hard link has no target for name resolution to follow, so a link inside an
allowed root looked like an allowed destination while sharing its inode with a
file outside every root. A caller that truncated the approved name in place
rewrote that outside file: `auth qrcode --output <link>` reported success and
replaced a 43-byte JSON file outside the allowlist with its PNG.

Output validation now refuses an existing target that carries more than one
name, which covers callers that write directly, and auth qrcode commits
through a temp file and a rename, which replaces the directory entry and
leaves the other names alone. Writers already going through FileIO.Save were
never affected, since that path has always committed by rename.

* fix(vfs): give the hard-link refusal a workable recovery hint

The message told the caller to copy the file into an allowed directory, which
answers a question they did not ask: the file that triggers this is normally
already inside one, with every one of its names there too. It now states what
the check actually cannot do — enumerate the other names a file is reachable
by — and offers the step that works, which is to copy the file and use the
copy.

* test(vfs): pick the denylist fixture for the platform under test

Two tests reached for "/etc/passwd" as a denylisted absolute path. That path
is not absolute on Windows, so one test met the foreign-path rejection instead
of the denylist it was asserting, and the other saw the path joined to the
working directory and no rejection at all. Both now ask for a deny root that
exists on the platform running them — the credential directories under the
account home qualify everywhere — which keeps the denylist covered on Windows
rather than skipping it there.

Verified on Windows 10.0.19045 by running the package's test binary from this
branch and from main: main passed, this branch failed these two, and both pass
after the change. The other packages this branch touches were compared the
same way and their Windows results are identical on both sides.

* fix(vfs): state the hard-link check as the condition it tests

The check read as "bail out unless the target can be inspected", which
nilerr reads as an error swallowed on the way out. It now names the case it
acts on — an existing regular file with more than one name — and the comment
carries what the early return used to imply: a target that cannot be
inspected has no link count to judge, and the write layer reports the real
failure with proper typing.

* docs(vfs): scope the policy's environment claim to what holds

The header promised that neither list accepts runtime input and that no
caller controlling the environment can widen them. Two inputs contradict
that: LARKSUITE_CLI_CONFIG_DIR contributes a deny root, and where the account
database cannot name the running uid, $HOME decides where ~/files points —
reproduced in a container running as an unregistered uid, which wrote into a
directory the environment chose.

The comments now state the preference and its boundary rather than a
guarantee, and record what the boundary costs: a directory named "files"
under the named path, with the home directory itself still outside the
allowlist and every candidate home still carrying the credential deny roots.
The trustedHome note also said the pure-Go lookup falls back to $HOME
silently; it does so only when $USER is set as well, and returns an error
otherwise, which drops the ~/files root instead of moving it.

No behavior change.

* fix(auth): keep the mode of a QR output file that already exists

Committing the QR write by rename fixed a hard link from rewriting a file
outside the allowlist, but it also changed what happens to the target's mode.
A rename installs the temp file's inode, mode included, where the previous
in-place write left the existing file's mode untouched. Overwriting a target
the caller had restricted to 0600 therefore published it as 0644.

The mode now comes from the file already at the path; only a path with
nothing at it takes the default. Verified against main, which preserved 0600
here, and covered by a test that fails when the fixed mode is restored.

* test(sheets): move the csv file-alias tests onto the new path baseline

Merging main brought larksuite#2559's tests for the --file → --csv alias, written
against the policy this branch replaces. Two of them fail on it, both because
the verdict they describe moved rather than disappeared.

The out-of-tree case used /tmp, which the allowlist now accepts, so the value
came back as a missing file instead of an out-of-tree one; it now names a path
no allow root can contain. The directory case is refused when the descriptor
is inspected, before a read is attempted, so the message reads "not a regular
file". What the caller sees of both — the flag named, the cause kept, stdin
offered — is unchanged.

That message listed the kinds it refuses and omitted directories, which is how
it reached a directory test reading as a mismatch. It now names them.

* fix(im): let the path policy judge a download target

`+messages-resources-download` refused an absolute --output before the shared
policy saw it, so the flag stayed relative-only after the policy learned to
accept full paths. It is the command behind 99% of a reported 1,189 download
path errors in one week, where 97.2% of first calls passed an absolute path
and every later success had switched to a relative one.

The shape checks are gone. Both call sites already hand the result to
ResolveSavePath, which applies the allowlist, the denylist and symlink
resolution, so refusing a shape here decided nothing the policy would not
decide better — an absolute path is now answered by where it points rather
than by how it is written.

The file-key checks stay, and they are what the batch caller relies on: it
embeds the key in the path, and a key carrying a separator is refused as a
malformed key, so a traversal cannot be built from one. Verified against a
real tenant: /tmp and ~/files now save, while ~/.ssh, /etc and a path outside
every root are still refused.

* test(im): pin the download output contract the policy now decides

The dry-run suite listed an absolute path among the values --output must
refuse. That held while the command rejected the shape itself; now that the
built-in policy decides, /tmp is an allowed root and the path is accepted, so
the case asserted a rule that no longer exists.

It is replaced by the two halves of the real contract: an absolute path
inside an allowed root reaches the request, and a path that resolves outside
every root — a parent escape from this working directory, or a denylisted
directory — is still turned down as a validation error naming --output.

* fix(vfs): hold a relative path to the working directory

Accepting /tmp as an allow root gave a relative path somewhere new to go.
A process whose working directory sits under /tmp — CI runners, containers
and agent sandboxes commonly arrange that — could climb out with "../" and
still satisfy the allowlist, because the sibling it landed in was also under
/tmp. /tmp is world-writable, so that sibling can belong to another user or
another session, and the write side commits by rename, which replaces an
existing target unconditionally. The previous policy refused this: it
required every resolved path to stay under the working directory.

Naming a full path and climbing out of the working directory are different
acts and no longer share one verdict. An absolute path is judged by the
allowlist, which is what this branch set out to allow; a relative one has to
resolve inside the working directory, whatever wider root contains it.

The home denylist grows at the same time and for the same reason: the working
directory is an allow root and running from the home directory is ordinary,
so a credential store there is reachable by a relative name unless the list
covers it. It now names the common ones — netrc, git and shell credentials,
kube, docker, azure, gh, gcloud, the language package registries — and the
shell histories, which carry pasted keys as reliably as a credential file.
