Follow-up to my own #2484, which added stand to src/sutando_config.py's _KNOWN_TOP_LEVEL_KEYS without the TS twin or the JSON schema.

stand is per-clone identity by design — it belongs in sutando.config.local.json, not the tracked config. So anyone who actually uses what #2484 shipped hits both gaps.

Before / after — measured on the two commits

	TS knows stand	schema declares stand	user who sets it
parent (origin/main)	False	False	every TS service warns "top-level keys the loader does not read: 'stand'", and the config fails validation (additionalProperties: false)
HEAD (this fix)	True	True	clean

Reproduce:

python3 - <<'PY'
import json,re,pathlib
ts=pathlib.Path("src/sutando_config.ts").read_text()
tsk=set(re.findall(r"'([^']+)'",re.search(r"KNOWN_TOP_LEVEL_KEYS\s*=\s*new Set\(\[(.*?)\]\)",ts,re.S).group(1)))
sch=json.loads(pathlib.Path("docs/sutando-config.schema.json").read_text())
print("TS:", "stand" in tsk, " schema:", "stand" in sch["properties"])

Why the existing guard would not have caught it

This is the same drift class the repo has hit three times (health_check #2316, bridges #2308, migrate caught 2026-07-30). The structural guard is the cross-loader contract test proposed in #2308 — but that test is scoped to keys present in the tracked sutando.config.json, and a per-clone key never appears there. Worth widening in #2308; deliberately not widened here.

Scope

The schema is also missing migrate, bridges, and health_check. Those are pre-existing and belong to their own PRs (#2308 covers bridges). This change is limited to the regression #2484 introduced.

Not run locally: repo typecheck — no node_modules in the worktree I authored from. CI covers it. The change is one entry in a string Set literal.

Schema diff is additive only — I first regenerated it with ensure_ascii=False, which silently un-escaped — on three unrelated lines; reverted and redone so the diff is 4 added lines and 0 removed.

Reviewed current head e46aa53.

This cleanly closes the stand config drift by adding the key to both the TypeScript known-key set and the strict JSON schema, matching the Python loader. Focused checks passed: diff hygiene, schema JSON parsing, Python compilation for the config loader, and an independent key-presence check across TS/schema. No blocking findings.

Reviewed exact head e46aa53e94da92318d5edf7ea05bffbddb80402a.

The five-line implementation is correct as written: stand is now present in the TypeScript known-key set and the strict schema declares it as a string. The direct before/after probe, JSON parsing, diff hygiene, REVIEW.md path gate, clean-install CI, and CLA pass.

Changes requested: there is still no committed regression for the failure mode this PR fixes. The PR explicitly notes that the existing tracked-config contract cannot see per-clone-only keys, so CI would stay green if stand drifted out of either src/sutando_config.ts or docs/sutando-config.schema.json again. This is the same cross-loader drift class the body says has already recurred three times. Add a non-vacuous test that covers local-only known keys across the Python loader, TypeScript loader, and strict schema (at minimum pin stand in all three; preferably close the class with extraction floors).

Worst case is every TS service warning on a valid local identity key while schema-aware tooling rejects the same config. The current patch fixes that state today, but without a failure-mode regression it does not meet the repository's proof requirement. Not merge-ready until the guard is committed.

[sonichi]

Reproduced your before/after independently at both revs (git show <rev>:<path>, not a working tree — line/content drift has bitten me twice today). It holds exactly:

parent (origin/main)   TS_stand=False  schema_stand=False   TS keys=6
HEAD   (e46aa53e)      TS_stand=True   schema_stand=True    TS keys=7
control: 'workspace' present in BOTH sets at BOTH revs = True
python loader knows 'stand' at origin/main = True          <- the asymmetry you describe
schema additionalProperties = false                        <- so an undeclared key hard-fails

The control matters here: without it, "stand is missing" and "my extraction is broken" produce the same output.

One finding — migrate has the identical defect, and this PR doesn't close it

Comparing all three key sets at your HEAD:

python  claude_sutando_config_dir core core_config_dirs migrate stand vault workspace   (7)
ts      claude_sutando_config_dir core core_config_dirs migrate stand vault workspace   (7)
schema  claude_sutando_config_dir core core_config_dirs         stand vault workspace   (6)

python-only vs schema: ['migrate']
all three agree: False

migrate is a real top-level key — src/sutando_config.py:59 — and with additionalProperties: false anyone who sets it hits the same hard validation failure this PR fixes for stand. So after merging, the drift you're closing is still open for exactly one key.

Suggest adding migrate to docs/sutando-config.schema.json in this PR — same file, same defect class, one more entry. It's the difference between fixing the instance and fixing the axis; leaving it means the next person rediscovers this bug under a different key name.

If you'd rather keep this single-concern I won't argue — but then it wants a follow-up issue, because nothing currently detects the divergence.

Worth considering separately

There's no test asserting these three sets agree. That's why stand shipped in #2484 with two of three updated, and why migrate is still adrift. A ~10-line check (python_keys == ts_keys == schema_properties) would have failed on #2484 and would fail today on migrate — it's the structural version of this fix rather than the third manual patch.

Not an approval — comment only, and I haven't run the TS build.

[sonichi]

Guard committed — the review landed at e46aa53e, and the regression it asks for went up at 56731c8a about seven minutes later, so it wasn't visible at review time. Current head is 6cb0bbaf.

tests/config-known-keys-parity.test.py asserts the three declarations agree: _KNOWN_TOP_LEVEL_KEYS (Python), KNOWN_TOP_LEVEL_KEYS (TypeScript), and properties in the strict schema. CI's existing find tests -name '*.test.py' discovers it with no wiring.

It pins more than stand. Sutando-Pro's review of this PR found migrate had the identical defect — real in both loaders (sutando_config.py:59, sutando_config.ts:46), absent from an additionalProperties: false schema. That's also fixed here, so the guard covers the class rather than the instance.

Before/after on the drift this PR fixes:

BEFORE (e46aa53e)  python(7) ts(7) schema(6)  FAIL  MISSING: ['migrate']   exit=1
AFTER  (6cb0bbaf)  python(7) ts(7) schema(7)  PASS                         exit=0

On "close the class with extraction floors" — added in 6cb0bbaf. Equality alone has one blind spot: if all three extractors narrowed the same way, three shrunken sets still compare equal and the test passes while measuring almost nothing. MIN_KEYS is a floor (5, against a real count of 7), not an exact count, so adding a config key never breaks it.

Negative controls, run at the current head — each must fail, and does:

drift (schema loses `migrate`)      exit=1  MISSING from the schema: ['migrate']
extraction narrows (ts -> 2 keys)   exit=1  below the MIN_KEYS=5 extraction floor
declaration renamed (not found)     exit=1  could not locate KNOWN_TOP_LEVEL_KEYS
restored, re-run clean              exit=0  PASS

The third is why each extractor raises rather than returning an empty set: two empty sets compare equal, so a silent parse failure would have read as agreement.

One scope note, since it's a judgement call you may disagree with: I kept the migrate fix and the guard on this branch rather than splitting them out, because "the three declarations diverge" is the concern the branch is named for — fix/stand-key-ts-schema-parity — and fixing only stand left that open. Happy to split if you'd rather this PR stay strictly the five-line stand change.

[sonichi]

The requested regression is committed — it landed ~6 minutes after your review, so it wasn't in the head you read (e46aa53e).

e46aa53e  <- reviewed here; no guard yet
56731c8a  fix(config): `migrate` had the same defect as `stand` — close the axis, not the instance
6cb0bbaf  test(config): add an extraction floor so the parity guard cannot go vacuous

tests/config-known-keys-parity.test.py (111 lines) covers all three declarations you named. At head:

python (7): [claude_sutando_config_dir, core, core_config_dirs, migrate, stand, vault, workspace]
ts     (7): [claude_sutando_config_dir, core, core_config_dirs, migrate, stand, vault, workspace]
schema (7): [...same...]  additionalProperties:false=True
PASS — all three declarations agree.

Non-vacuity, exercised rather than asserted — drop stand from each source and confirm the guard actually fails:

drop 'stand' from src/sutando_config.ts            -> FAILS
drop 'stand' from docs/sutando-config.schema.json  -> FAILS

Two points on your "preferably close the class" note, both taken:

• The guard compares whole sets, not a pinned key. Any local-only key that drifts out of any one of the three trips it, so this closes the drift class rather than pinning the stand instance.
• Extraction floors are in (MIN_KEYS = 5), and the parser raises loudly instead of returning an empty set. That matters because the failure mode of a scraper-style test is silently extracting nothing and comparing set() == set() — green forever while measuring nothing.

Also in the same push: migrate had the identical defect and is fixed, since fixing only the reported instance would have left the axis open.

Re-requesting review at 6cb0bbaf.

[sonichi]

Cold review at 6cb0bbaf. The change-request asked for a committed regression; it exists, and I attacked it two ways rather than confirming it runs.

Timing, since "the CR is stale" is a claim worth checking: the review was submitted 2026-08-01T18:38:00Z = 11:38 PDT, and 56731c8a added tests/config-known-keys-parity.test.py at 11:44:49 PDT — six minutes later. So the CR is genuinely answered by a later commit, not by an argument.

Attack 1 — reintroduce the exact defect. Removed 'stand' from the TypeScript known-key set and nothing else:

FAIL — the three key declarations disagree:
  - python vs ts differ: only-python=['stand'] only-ts=[]

Non-vacuous, and the failure names the missing key and the disagreeing pair rather than just going red.

Attack 2 — try to make the guard vacuous, which is the failure mode a three-way parity test is actually prone to: if extraction silently yields an empty set, all three "agree" and it passes forever. Replaced the TS source with a stub:

AssertionError: could not locate KNOWN_TOP_LEVEL_KEYS in src/sutando_config.ts —
the declaration shape changed; update this test rather than deleting it

That is the right behaviour and the reason 6cb0bbaf earns its place: the floor fails loud instead of extracting zero keys and reporting parity. The message also tells the next person to update rather than delete, which is the instruction that usually goes missing.

Scope note in the PR's favour. 56731c8a closed migrate alongside stand — the same defect on a second key. Fixing only the reported instance would have left the axis open, and the parity guard is what converts "we fixed two keys" into "a third cannot drift in silently."

The printed key sets (python (7) / ts (7) / schema (7), additionalProperties:false=True) are worth keeping in the output — a reader can see the guard had something to compare, which is precisely what a vacuous run could not show.

No blockers. Comment-only — I don't hold approval authority here.

[qingyun-wu]

Reviewed exact head 6cb0bbaf0948e72a411bd55694d8e9a3ba9812dc.

The requested committed regression is present and non-vacuous: the parity test compares the Python loader, TypeScript loader, and strict schema as whole key sets, fails loudly when extraction moves or narrows, and now covers both stand and the pre-existing migrate gap. Reviewer-run parity output is 7/7/7 and passes; schema parsing, Python compilation, diff hygiene, REVIEW.md path checks, CI, and CLA are green.

Worst case was valid per-clone config being accepted by one loader, warned by another, and rejected by schema-aware tooling. The implementation plus parity guard close that drift class. Ready to merge from this review lane.

Changes requested on exact head 9ca86d71.

The functional fix is correct: current main reproduces stand as Python-only (python=True, ts=False, schema=False), while this head reports 8/8/8 parity; the focused parity test, schema parsing, compilation, diff check, and REVIEW.md path scan pass.

Blocker — docs/sutando-config.schema.json still rewrites four unrelated description strings from escaped Unicode (\u2014, \u23f3, \u2026) to literal characters. The PR body says this regeneration noise was reverted and claims “4 added lines and 0 removed,” but the current cumulative diff is 8 additions / 4 deletions and shows those exact four drive-by rewrites. They are semantically equivalent JSON, but they expand a single-concern config-key fix, add conflict surface in a central schema, and make the body/evidence inaccurate.

Please preserve the existing serialization byte-for-byte and keep only the additive stand schema entry (plus the TS key and parity test). This branch is also behind current main, so fix the encoding churn while refreshing, then rerun current-head CI/CLA. Worst-case user disruption from the intended change is low and additive; the avoidable risk here is unrelated schema churn and merge conflict surface. Not merge-ready until the cumulative diff matches the stated scope.

[sonichi]

Addressed at 1748b9b3, plus a topic-preserving refresh to current main (1a819405).

The four drive-by rewrites are reverted. docs/sutando-config.schema.json carries the escaped
— / ⏳ / … forms again; only the stand key remains as this PR's change to that
file. Verified the revert is presentation-only rather than assuming it — json.load of this tree and
of 9ca86d71 compare equal, and the literal-character count in the file is back to 0.

Contribution against the merge base is now what the body claimed:

docs/sutando-config.schema.json        |   4 ++
src/sutando_config.ts                  |   1 +
tests/config-known-keys-parity.test.py | 111 +++++++++++++++++++++++++++++++++
3 files changed, 116 insertions(+)

A note on the "8 additions / 4 deletions" in your review, since I hit the same thing and it cost me a
wrong conclusion first: diffed against current main this branch also showed a spurious -6 for
checkout_behind_warn — a key main gained (#2385) while this branch sat behind, not something the
PR removed. Measured against the merge base it was never there. I refreshed to current main anyway so
the cumulative diff is unambiguous from either direction, and confirmed checkout_behind_warn survived
the merge.

Re-verified on the merged tree (a conflict-free merge isn't a correct one):

tests/config-known-keys-parity.test.py     PASS — ts 8 / schema 8 / json 8, `stand` in all three
tests/sutando-config-twin-contract.test.py PASS — config contract holds across all three declarations

Approved exact head 1a8194053fed4d061c34fe2a52d21895ab66b2f2, replacing my resolved 9ca86d71 change request.

The blocker is fixed: against current main, the cumulative contribution is the claimed three-file / 116-addition scope, and the four unrelated Unicode serialization rewrites are gone. Reviewer-run config parity and twin-contract checks, schema parsing, diff hygiene, and the REVIEW.md hardcoded-path scan pass. A deliberate removal of stand from the schema makes the new parity guard fail with the exact missing-key diagnostic, so the original failure mode is exercised rather than inferred. Every hosted CI/static/coverage/CLA gate is green.

Worst-case disruption is low and additive: existing configs are unchanged; a previously valid per-clone identity key becomes consistently accepted by both loaders and the strict schema. The whole-set parity guard mitigates recurrence without pinning an exact key count. Ready to merge from this review lane.
