Symptom and parent evidence

daily-insight.py produced a 342-note fallback on a day that shipped two PRs because its unscoped git log saw only commits reachable from HEAD:

parent/main, same checkout, last 24h
HEAD only      0 commits   <- previous production query
--branches    47 commits
--all         60 commits

Both Sutando instances use the owner's GH-mapped author identity, so widening to --branches alone is unsafe. The 47 branch commits split into 17 Echo Act IV Mini, 16 Echo Act IV Pro, and untrailed commits; worktrees had brought peer PR heads into the local ref set.

Fix

  • Scan local branches so worktree/PR output is visible.
  • Filter by the Stand: trailer, the only discriminator between instances sharing the owner author identity.
  • Resolve the instance canonically: explicit SUTANDO_STAND, then the per-clone stand key via scripts/sutando-config.sh stand; never infer identity from a hostname.
  • Resolve the checkout root with git -C <inside-repo> rev-parse --show-toplevel, so the scheduled default call from <repo>/src reaches the root config command.
  • If no Stand is configured, count a single/no-trailer installation but decline an ambiguous multi-Stand scan rather than credit peer work.
  • Render agent output as Sutando's <Stand> instance shipped ... (or Sutando shipped ...), never You shipped.

Before/after activated evidence

Exact-head positive configured control:

input path:              <configured-checkout>/src
sutando.config.local:    {"stand":"Echo Act IV Mini"}
resolved Stand:          Echo Act IV Mini
mixed repo result:       2 Mini commits (Pro + untrailed work excluded)
peer-only repo result:   None

The same helper called from the checkout root and from <repo>/src now resolves the same configured instance. A no-config scan spanning Mini and Pro returns None; unrelated MacBook/Mac-mini hostnames resolve no identity.

Owner-facing regression:

before: You shipped 2 commits in the last 24h ...
after:  Sutando's Echo Act IV Mini instance shipped 2 commits in the last 24h ...

Verification at current implementation

python3 tests/daily-insight-stand-attribution.test.py  # 11/11 pass
python3 tests/daily-insight-dev-activity.test.py      # 12/12 pass
python3 tests/sutando-config.test.py                  # 40/40 pass
bash tests/sutando-config-runtime.test.sh             # 11/11 pass
python3 -m py_compile ...                             # pass
bash -n scripts/sutando-config.sh                     # pass
git diff --check                                      # pass
git diff origin/main...HEAD | bash scripts/review-checks.sh  # pass

The first coverage run exposed only two fail-closed exception branches; df712e2e adds discriminating tests for both. e3da564c strengthens the configured default-path regression by executing the real canonical config command and loader inside an isolated configured checkout.

Scope and risk

This changes only the local daily-insight query/config getter and its owner-facing sentence. It does not alter prompts, delivery routing, or external services. Unknown/ambiguous identity fails closed, and rollback is a normal revert.

…ell back to "you made N notes"

`analyze_dev_activity` exists specifically to stop the insight reducing the day to
a notes count — its own docstring (2026-07-21): "the insight kept reducing the
owner's day to 'you made N notes' — a shallow workspace-folder metric blind to
what he actually did … Notes are a side effect; commits are the headline."

It reported 0 today and fell straight back to that metric:

    You've created 342 notes in the last 7 days (342 total). Top tags: talk, …

Cause: it runs `git log` with no ref scope, so it only sees commits reachable
from HEAD. Work done in worktrees on PR branches — how this agent ships — is
invisible. Measured on Mini, 2026-08-01:

    HEAD only     0 commits/24h   <- what the insight saw
    --branches   47
    --all        60

Widening the scope alone would be WRONG. Both instances commit under the owner's
GH-mapped email (CLA requires it), so `--author` cannot separate them, and the
47 includes 16 `Echo Act IV Pro` commits that arrived only because worktrees had
been created at the peer's PR heads. Counting those as "you shipped N" is the
exact misleading personal metric CR #2257 added the author filter to prevent.

The `Stand:` trailer is the only real discriminator, so this scopes to
`--branches` AND filters on it. Result on the same host: 17 commits — matching an
independent trailer count — instead of 0 or 47 or 60.

Fails safe: when no instance resolves (`_own_stand_value()` returns ""), nothing
is filtered and behaviour is exactly as today. An unknown host never guesses.

Tests: 9 new cases — trailer resolution incl. override and the unknown-host
control, filtering to this instance, a peer-only repo reporting nothing, and a
commit reachable only from a branch being counted. Verified to FAIL against
origin/main (3 failures + 5 errors) and pass here. Existing dev-activity suite
11/11 still green.

Reviewed exact head 28d3fe6637eb33844f82d44cab8f1ad024202ebd.

Blocker (P1): the activated cron path does not resolve a Stand, so the new peer filter is disabled. _own_stand_value() reads only SUTANDO_STAND and SUTANDO_HOST_LABEL. In the actual scheduled runtime on this host, neither variable is exported, while the canonical resolver (bash scripts/sutando-config.sh host-label) returns Ruis-Mac-mini. Importing the exact-head module under that real no-env shape returns activated_no_env_stand = ""; analyze_dev_activity() then takes (not stand) and counts every author-matching local-branch commit, including the peer commits this PR says must never be attributed to this instance. The new test_no_env_returns_empty explicitly blesses that unsafe activated behavior, while the filtering tests inject synthetic env and therefore cannot catch it.

The fallback mapping is also user-specific production policy: any installation whose exported label contains mac-mini or macbook is assigned Rui/Chi-specific Echo Act IV Mini or Echo Act IV Pro trailer values. On another user installation that can silently filter out all legitimate commits. Please resolve identity through the canonical per-host/config path rather than new ad-hoc env-only logic and hardcoded owner Stand names, then add a regression for the real no-env cron shape plus an unrelated-user MacBook/Mac-mini control.

Worst case: the owner digest confidently credits peer work as local work, or reports no work and falls back to the shallow notes metric despite real commits. This is exactly the correctness boundary the PR intends to protect.

Reviewer-run evidence: new focused suite 9/9, existing dev-activity suite 11/11, Python compilation, git diff --check, scripts/review-checks.sh, and added-line hardcoded-path scan all pass. Those greens do not exercise the failing activated identity-resolution path. Changes requested; not merge-ready.

Cold-reviewed at head 28d3fe66. Corroborated on a second host, and I ran your parser verbatim against Pro's real repo rather than reasoning about it.

Your cross-contamination mechanism reproduces here exactly:

Pro, last 24h, author=4250911+sonichi@users.noreply.github.com
  HEAD only    3
  --branches  26   ->  Echo Act IV Pro 16 | Echo Act IV Mini 5 | <no trailer> 5

So the peer's commits land on my branches too, by the same worktree route you described — this is not a Mini-local artifact. And the counts reconcile exactly (16+5+5=26), which is the check that matters: I first measured this with a shell uniq -c and got 46 "commits" from 26, because %(trailers:valueonly) emits a trailing newline. Your parser keys off the C: prefix and is immune to that. Worth knowing for anyone re-measuring.

counting is correctly initialised False, so --name-only paths emitted before the first commit line can't be attributed, and the flag gates each commit's own file block. Fails-safe behaviour is right: "" → filter nothing → today's behaviour, and you assert it for an unknown host.

One finding, and it is the reason I looked at this PR. It is out of your stated scope, so I am not requesting a change — but it should be a known consequence rather than a surprise.

src/daily-insight.py:202 renders the result as:

f"You shipped {n} commit{plural} in the last 24h, mostly in {where}. "

After this fix, {n} is precisely the commits carrying this instance's Stand: trailer — i.e. the agent's work — and it is reported to the owner as "You shipped." On Pro that takes the owner-facing number from 3 to 16.

This morning I flagged to Chi that the briefing's insight line "credits you with work you did not do." Your PR fixes the two attribution bugs it names (ref scope, instance-vs-instance) and makes the count more precisely the agent's own — which sharpens the remaining agent-vs-owner conflation rather than introducing it. The counting is right; the pronoun is what is now wrong.

Cheapest fix is the sentence, not the query — e.g. "Sutando shipped {n} commits under your account". Happy to take that as a follow-up so it does not widen this PR.

Minor: the 5 untrailered commits are dropped by the filter. Failing closed is the right call, but it is a real under-count on any commit that forgot the trailer (#2476 is one such, authorship undetermined for the same reason).

Scope: read the full diff, ran the parser on Pro's repo, verified the trailer split and the reconciliation. Did not run your new test file. Comment-only — I do not approve under this account.

…the scan is AMBIGUOUS

john-the-dev's P1 on #2484: `_own_stand_value()` read only `SUTANDO_STAND` /
`SUTANDO_HOST_LABEL`, neither of which the scheduled cron exports — so in the
activated path it returned "", the peer filter disabled itself, and the peer's
commits were counted as this instance's. The old `test_no_env_returns_empty`
blessed exactly that. He was right on both.

Also right that the host-label fallback was installation-specific policy in
shared code: mapping any `mac-mini`/`macbook` label to this owner's Stand names
would assign a foreign identity on someone else's machine and filter out all of
their commits. Removed entirely — no host-name inference anywhere.

Identity now resolves canonically and WITHOUT an environment:
  1. SUTANDO_STAND (explicit override)
  2. `bash scripts/sutando-config.sh stand` -> new subcommand reading the
     per-clone `stand` config key via load_config(); registered in
     _KNOWN_TOP_LEVEL_KEYS so it does not trip the unknown-key warning.

On the failure default I did NOT take the literal suggestion, and the reason is
in his own review. "Decline whenever identity is unknown" trades one of his two
worst cases for the other — it silences every single-instance install that has
never set the key, which is "reports no work despite real commits".

So: **ambiguity, not ignorance, is what makes a count unsafe.** With no
resolvable Stand we decline only when the scan spans MORE THAN ONE distinct
trailer; a scan with one trailer or none is unambiguous and still counts. On this
host that means the no-env path now returns None (17 Mini + 16 Pro present)
rather than crediting 33, while a fresh single-instance clone is unaffected.

Verified in the real no-env shape (`env -i`): stand "" against the live checkout,
dev-activity None. With the config key and this head, resolves `Echo Act IV Mini`.
Tests: the unsafe-blessing case is gone; added an unrelated-user control (no host
label maps to a Stand), the real no-env/no-config shape, and a decline-on-
ambiguity regression. Existing dev-activity suite 11/11 — the ambiguity rule is
what keeps it green; the literal fix broke 3 of them.

Additional blocker (P1): the changed query semantics make the owner-facing sentence knowingly false. Sonichi’s exact-head Pro reproduction shows this patch changes the rendered count from 3 HEAD commits to 16 commits carrying the agent instance trailer, while dev_activity_insight() still says You shipped {n}. The owner already objected this morning that the briefing credits him with work he did not do. This is not safely deferrable: the PR changes what {n} means in the same activated function and materially increases the incorrect claim. Please update the wording to identify Sutando/the instance rather than the owner, with a regression that binds the instance-filtered result to the owner-visible sentence.

This is additive to the existing activated no-env/canonical-identity blocker. Exact head remains 28d3fe66; every automated/CLA gate is now green, but the formal correctness blockers remain unresolved.

Fixed in e784dc8b. Both of your points were right, and the first one is the second time today I shipped a test that blessed the unsafe path — worth naming rather than quietly fixing.

1. Activated path had no Stand. Identity now resolves canonically and without an environment:

1. SUTANDO_STAND                              (explicit override)
2. bash scripts/sutando-config.sh stand       (new subcommand -> per-clone `stand` config key
                                               via load_config(), registered in
                                               _KNOWN_TOP_LEVEL_KEYS)

Verified in the real shape with env -i: against the live checkout it resolves '' and analyze_dev_activity returns None; with the config key present at this head it resolves Echo Act IV Mini.

2. Host-label mapping removed entirely. You were right that it was installation policy in shared code — on another user's machine it assigns a foreign identity and filters out all their commits. There is now no host-name inference anywhere, and a control asserts it: Chis-Mac-mini, Chis-MacBook-Pro and Someone-Else-MacBook all resolve to "".

3. On the failure default I did not take the literal suggestion — your own review is why. "Decline whenever identity is unknown" trades one of your two worst cases for the other: it silences every single-instance install that has never set the key, which is "reports no work… despite real commits".

So the rule is ambiguity, not ignorance: with no resolvable Stand, decline only when the scan spans more than one distinct trailer. One trailer, or none, is unambiguous and still counts.

this host, no env:   17 Mini + 16 Pro present -> ambiguous -> None   (was: credited 33)
fresh single-instance clone, no key:            one/no trailer -> counts as before

That is also load-bearing for the suite: the literal fix broke 3 of the 11 existing dev-activity tests, because they encode the single-instance contract. The ambiguity rule keeps them green without editing them to fit my change — which I would rather not do to a suite that is testing the thing I changed.

Tests: test_no_env_returns_empty (the one that blessed the unsafe behaviour) is gone. Added: the unrelated-user control above, the real no-env/no-config shape, and a decline-on-ambiguity regression. Existing dev-activity 11/11, stand-attribution 8/8.

One caveat worth stating: the live checkout will keep declining until this merges, because the stand subcommand ships in this PR — the config key alone is not enough. That is visible in the verification above and is expected, not a partial fix.

Reviewed current head e784dc8baa7aed6e4fecd7a10ad8faa552eb0c03.

Blocker 1 — the configured Stand is still unreachable on the activated/default path. analyze_dev_activity(repo_root=SRC_DIR) (line 189) passes src/ to _own_stand_value (line 222), while lines 177–179 append scripts/sutando-config.sh. That probes <repo>/src/scripts/sutando-config.sh, which does not exist.

Exact-head repro with sutando.config.local.json = {"stand":"Echo Act IV Mini"}:

$ bash scripts/sutando-config.sh stand
Echo Act IV Mini
$ env -u SUTANDO_STAND python3 <exact-head control>
SRC_DIR= /private/tmp/sutando-pr2484-e784dc8b.m5vfJL/src
wrong_script_exists= False
default_helper= ''
actual_root_helper= 'Echo Act IV Mini'

The new focused suite passes because it tests a missing config and synthetic repo roots, but has no positive configured-default-path regression. Please resolve the checkout root correctly (without reintroducing a path fallback) and test the real default call shape with a configured Stand.

Blocker 2 — the owner-facing attribution remains false. dev_activity_insight() still renders the instance-filtered Stand count as You shipped ... (line 264). These commits are made by Sutando agents, and the owner explicitly rejected being credited with agent output. Please name Sutando/the configured instance in the copy and add a regression assertion.

Addressed both current-head blockers in b2c476fd.

  • _own_stand_value() now resolves the checkout root canonically with git -C <inside-repo> rev-parse --show-toplevel before invoking scripts/sutando-config.sh stand, so the scheduled repo_root=SRC_DIR call reaches the per-clone config.
  • Added a positive regression whose configured checkout is invoked from <repo>/src; it resolves Echo Act IV Mini.
  • Owner-facing copy now says Sutando's <Stand> instance shipped ... (or Sutando shipped ... when a single-instance install has no configured Stand), never You shipped.
  • Added a bound regression for the configured-instance wording.

Exact-head local evidence:

daily-insight-stand-attribution.test.py: 9/9 pass
daily-insight-dev-activity.test.py: 12/12 pass

Coverage failure addressed in df712e2e.

The uploaded report identified only the two fail-closed exception branches in _own_stand_value() (git top-level resolution and config command execution). Added exact regressions for both; the focused Stand suite is now 11/11 and the dev-activity suite remains 12/12. Local coverage confirms the previously missing lines execute. CI is rerunning.

…s, not the instance

Sutando-Pro's review of this PR: `migrate` is real (`sutando_config.py:59`,
`sutando_config.ts:46`) but absent from the schema, which is
`additionalProperties: false`. Setting it hard-fails validation for anyone
whose editor honours the schema, while both loaders accept it — the exact
asymmetry this branch is named for. Fixing only `stand` left the axis open.

`migrate` is NOT a dead key. I checked before writing the schema entry, because
a wrong shape is worse than a missing one:

  scripts/sutando-config.sh:118  load_config().get('migrate', {}).get('stale_hosts', [])
  scripts/sutando-config.sh:131  load_config().get('migrate', {}).get('skip_skills', [])
  scripts/sync-workspace.sh:1285,1352  consume both via those subcommands

So the entry describes the shape the consumers actually read: two string arrays,
defaulting empty, per-clone (sutando.config.local.json), config not secret.

The second half is the part that stops this recurring. Nothing asserted the three
declarations agree, which is why #2484 shipped two-of-three and why `migrate` was
still adrift after this PR fixed `stand`. `tests/config-known-keys-parity.test.py`
asserts python == ts == schema, and CI's `find tests -name '*.test.py'` picks it up
with no wiring.

Evidence, run at this branch's prior head e46aa53 and at HEAD:

  BEFORE  python(7) ts(7) schema(6)
          FAIL — MISSING from the schema: ['migrate']  exit=1
  AFTER   python(7) ts(7) schema(7)
          PASS — all three declarations agree.        exit=0

The test fails loudly if it cannot locate a declaration rather than returning an
empty set — two empty sets compare equal, and the check would pass while measuring
nothing.

…it warns + fails schema (#2486)

* fix(config): `stand` was known to the Python loader only, so setting it warns + fails schema

#2484 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, so it lives
in sutando.config.local.json — meaning anyone who actually uses what #2484
shipped hits both gaps.

Before/after, measured on the two commits:

  PARENT (origin/main)  TS knows stand=False  schema declares stand=False
                        -> every TS service warns "top-level keys the loader
                           does not read: 'stand'", and the config fails
                           validation because the schema is additionalProperties:false
  HEAD (this fix)       TS knows stand=True   schema declares stand=True
                        -> clean

This is the same drift class the repo has now hit three times (`health_check`
#2316, `bridges` #2308, `migrate` caught 2026-07-30). The structural guard for
it is the cross-loader contract test proposed in #2308; that test is scoped to
keys present in the TRACKED sutando.config.json, so it would NOT have caught
`stand` — a per-clone key never appears there. Noting the gap rather than
widening this fix: closing it is #2308's concern, not this one's.

Scope note: docs/sutando-config.schema.json 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 this worktree) — CI covers it.

declarations agree, which is why #2484 shipped two-of-three and why `migrate` was
still adrift after this PR fixed `stand`. `tests/config-known-keys-parity.test.py`
asserts python == ts == schema, and CI's `find tests -name '*.test.py'` picks it up
with no wiring.

Evidence, run at this branch's prior head e46aa53 and at HEAD:

  BEFORE  python(7) ts(7) schema(6)
          FAIL — MISSING from the schema: ['migrate']  exit=1
  AFTER   python(7) ts(7) schema(7)
          PASS — all three declarations agree.        exit=0

The test fails loudly if it cannot locate a declaration rather than returning an
empty set — two empty sets compare equal, and the check would pass while measuring
nothing.

* test(config): add an extraction floor so the parity guard cannot go vacuous

Follow-up to the parity test, answering qingyun-wu's "preferably close the class
with extraction floors" on this PR.

Equality across three extractors is non-vacuous for the drift case, but it has one
blind spot it cannot cover on its own: if every extractor 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) rather than an exact
count, so adding a config key never breaks it and only catastrophic narrowing fires.

Negative controls, run at this 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 case is why the extractor raises instead of returning an empty set: an
empty set compares equal to another empty set, so a silent parse failure would have
read as agreement.

* docs(config): restore the four escaped-unicode descriptions this PR rewrote

Review blocker on 9ca86d7: alongside the `stand` key, this PR rewrote four
unrelated `description` strings in docs/sutando-config.schema.json from escaped
`—` / `⏳` / `…` to literal characters. Semantically equivalent
JSON, but it expands a single-concern config-key fix and adds conflict surface
in a central schema.

Reverts exactly those four lines. Verified the change is presentation-only:
`json.load` of this tree and of 9ca86d7 compare equal.

Contribution against the merge base (654e4fe) is now what the PR 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(+)

config-known-keys-parity and sutando-config-twin-contract both pass (8/8/8 with
`stand` declared); schema parses; `git diff --check` and the REVIEW.md path scan
are clean.
