5efe97c0ae docs(solutions): your environment is a variable in every measurement you report (#3291)
Extends the doc from #3255/#3273 with the failure that cost the most in
a single session: **one stale install produced five wrong reports on one
issue** (#3264).

## What happened

A `node_modules` that had drifted from the lockfile — `jsdom@29.0.1`
installed, `29.1.1` pinned — generated failures that existed on no CI
machine and no other checkout. They were not subtle: deterministic,
reproducible on demand, with plausible stack traces and real-looking
assertion diffs.

Each round of triage got **more precise about the wrong data**:

| round | claim | why it was wrong |
| --- | --- | --- |
| 1 | "4 deterministic failures" | measured in a 4-file batch, called it
isolation |
| 2 | "3 deterministic, 2 order-dependent" | isolated correctly, but a
race is not deterministic |
| 3 | "TaskCard is broken" | stale jsdom; the CSS assertion was correct
|
| 4 | "no contamination" | true of four app files; published unqualified
|
| 5 | "quarantine these two" | never read the failure text — both were
timeouts |

The through-line is not carelessness about the code. **The environment
was never treated as part of the claim**, so no amount of care about the
analysis could recover it.

## The checks, in the order they cost the most

```bash
pnpm install --frozen-lockfile   # node_modules is not evidence until it matches the lockfile
<run the file ALONE, 3+ times>   # isolation and repetition answer different questions
<read the failure TEXT>          # a timeout and an assertion failure need opposite responses
uptime                           # a loaded box manufactures timeouts that mean nothing
```

## Why the load check earned its place

Two tests "failing" in a full-suite run were `Test timed out in 15000ms`
on a box at **load average 9.7 with 84 users**. Under AGENTS.md's
quarantine-on-sight rule that reads as a flake to quarantine — and the
ledger's **14-day deletion ratchet would have made the lost coverage
permanent**.

The rule presumes the failure is a property of the test, not of the
machine. A wall-clock budget crossed under local contention is evidence
about the hardware. I was one comment away from deleting healthy
coverage on that basis.

## The tell

A finding is environment-derived when it is **local, recent, and
unshared**: nobody else has reported it, CI is green, and it appeared
without a commit that could explain it. Any two of those should stop a
report before it is written. All three applied here, and the report went
out anyway — five times.

## Verification

Docs only; no code paths change. `fnxc-future-dates`,
`lifecycle-columns`, `quarantine-ledger` exit 0. No changeset — internal
docs are excluded.

Context: the one finding in #3264 that survived all five rounds is #3286
(merged), and it survived because it was verified by **reverting the
product change** rather than by trusting a red — 3/3/2 failures without
the fix, 27/27 across four runs with it.

29eb512d57 docs(solutions): the general shape — a green that answers a different question (#3273)
Extends the doc merged in #3255 with two more instances of the same
pattern, both found this session, **neither involving a ratchet**. Four
instances now, from four unrelated directions:

| what was read as "pass" | what the green actually meant |
| --- | --- |
| `node scripts/check-*.mjs` exits 0 | report-only mode — the failure
path needs `--strict` |
| a census reports 0 for a new file | the file is untracked, so it was
never scanned |
| a backgrounded `cmd > log; grep …` reports exit 0 | that is `grep`'s
status; the suite inside had 8 failures |
| a rebased branch's tests pass | the rebase never started, so it ran on
the **old** base |

The two new ones are worth writing down because they are not about
tooling anyone built here — they are about how results are read.

**Exit codes belong to the last command in the pipeline.** A
backgrounded `run_tests > log 2>&1; echo done; grep X log` exits with
`grep`'s status, so the harness reported "completed, exit code 0" for a
dashboard suite that had 8 failures. I nearly recorded that suite as
green. Read the summary out of the log; never infer a suite's result
from a wrapper's exit code.

**A failed rebase leaves you on the old base, and the tests still pass
there.** `git rebase` refused with `cannot rebase: You have unstaged
changes`, so the branch never moved. `git diff origin/main` then listed
20+ files including other workers' commits — which reads exactly like my
branch had reverted their work — and a full test run on that tree came
back green. Both signals were true about a tree nobody cared about.

```
git merge-base --is-ancestor origin/main HEAD
```

said STALE while the tests said pass. That is the only check that
separates the two, and it belongs before any claim of "verified on
current main".

The shared tell, stated once: **a result too clean, or too alarming, for
what changed.** Every probe shape passing including ones that obviously
should not; a two-file branch appearing to revert twenty. When the
answer does not fit the size of the question, find out what was actually
measured before believing it.

## Verification

Docs only; no code paths change. `lifecycle-columns`,
`move-target-literals`, `inert-sync-lanes`, `quarantine-ledger` all exit
0. No changeset — AGENTS.md excludes internal docs.

**Pre-existing red, not from this branch:** `check:fnxc-future-dates`
currently fails on main from a `2026-08-01-00:50` stamp in
`packages/core/src/task-store/lifecycle-ops.ts` (commit `e52da740a5`) —
a timezone-ahead clock writing tomorrow's date, at 23:45 UTC. Already
claimed by **#3269 and #3270**, so I have not touched it; flagging only
so this branch's CI result is not misattributed. It is the same
recurring class this doc's sibling rule addresses: take the stamp from
`date -u`, not the local clock.

d14294b6cb docs(solutions): add the count-based probe, which the report-only trap cannot fool (#3257)
## What

Adds one technique to #3255. Docs only.

#3255 records that probing a ratchet **by exit code** can read green
because the tool is report-only without `--strict` — a real trap that
nearly got a healthy gate reported as dead. There is a second technique
that sidesteps it entirely and is strictly more informative: **parse the
tool's own per-file count.**

```bash
node scripts/check-move-target-literals.mjs 2>&1 | grep -a "my-probe-tmp" \
  | grep -aoE "^ +[0-9]+" | tr -d ' '
```

**Immune to the report-only trap** — a report-only run still *prints*
the count, so the number moves 0 → 1 whether or not `--strict` was
passed.

**It measures which shapes, not just whether something fired.** An exit
code is one bit for the whole run. Auditing a detector means asking *"of
these five spellings, which are seen?"*, and five separate binary runs
cannot distinguish **partial** detection from a probe file that failed
to compile. The move-target audit read `direct 1 / backtick 1 / ternary
0 / const 0` in a single run, which named the gap immediately.

## Both belong

| question | technique |
|---|---|
| **can this ratchet fail at all?** | `pnpm check:*` — ask this first
(#3255 §1) |
| **what can it see?** | per-file counts — an exit code is too coarse |

I also added a caveat that applies to both: confirm the probe is
actually being scanned by watching the tool's **scanned-file total**
move. A probe that never compiled and a probe the tool never discovered
both report zero hits, and neither is a finding — that one cost me a
wasted measurement before I noticed the total had stayed at 1961.

## Why this is worth a follow-up rather than a comment

#3255's rule as written — *"use `pnpm check:*`, not a bare `node
scripts/...`"* — would have made the shape-coverage audits impossible,
since `--strict` collapses five distinct per-form answers into one bit.
The rule is right for its question and wrong for the other one, and the
distinction is easy to lose once only the rule survives in someone's
memory.

9690f46439 docs(solutions): probe the instrument the way CI runs it (#3255)
Records two instrument-level defects found this session. Both were in
the tools the program uses as ground truth, and both looked exactly like
a pass.

## 1. A ratchet that could not fail from the command I typed

`check-move-target-literals` is report-only unless given `--strict`,
which `package.json` supplies. Probed bare, it returned **exit 0 for
every probe** — including a blatant `moveTask(id, "in-review")` pasted
into `scheduler.ts`.

That is the exact signature of a dead ratchet, and I nearly reported
another worker's guard as inert on the strength of it. The guard was
fine; my invocation could not fail. What makes it dangerous is the
output: a report-only run prints its normal summary line and exits 0, so
the terminal is indistinguishable from a genuine pass.

## 2. A ratchet that could not see the file I had just written

`lifecycle-column-census` and `check-move-target-literals` discovered
files with `git ls-files` — **tracked only** — while the other five walk
the filesystem.

| new file with a plain legacy guard | result |
| --- | --- |
| same guard in an already-tracked file | caught |
| new file, untracked | **missed, exit 0** |
| identical file, `git add`ed | caught, exit 1 |

The detectors are fine. The blindness is discovery, and it lands at the
one moment the number is consulted: add a helper, check your own work,
read zero, commit — and it surfaces later in someone else's CI run,
attributed to a push instead of to the edit. The tool was answering
about the last commit while being asked about the working tree.

## 3. Why it is worth a doc rather than two one-line fixes

Individually these are cheap. Together they cost a day.

Because `check-inert-sync-lane-conversions` walks the filesystem and the
census did not, the **same probe file** was caught by one and missed by
the other. I read that differential as a claim about expression walking
and investigated it as one — the real cause was that two instruments in
the same program disagreed about which files exist.

When the measuring tools disagree about their own domain, every
differential between them is unreadable until someone notices. That is
the transferable lesson, and it is not visible from either fix alone.

## Status of the fixes

- Census discovery scope: **#3254** (open).
- Type-assertion blind spot in the sync-lane ratchet: **#3252** (open).
- `check-move-target-literals` discovery scope: reported to **#3253**,
whose author is already in that file — not touching it.

## Verification

Docs only; no code paths change. All eight ratchets exit 0. No changeset
— AGENTS.md excludes internal docs.

59dfc4678b docs(solutions): record what each lifecycle ratchet cannot see, measured (#3251)
## What

This note already prescribes: *"Before trusting a ratchet: mutate the
shape it claims to catch and confirm it exits non-zero."* This is that
checklist item **executed against all five lifecycle gates** on one
tree, one staged probe file per form. Docs only.

**Two of the five were wrong.**

| gate | catches | does NOT catch |
|---|---|---|
| `lifecycle-column-census` | `===` / `!==` | ~~membership, switch~~
**fixed (#3247)** |
| `check-move-target-literals` | direct + backtick destinations |
~~ternary~~ **fixed (#3250)**; still misses a destination bound to a
local |
| `check-sql-column-literals` | `"column"` comparisons — **including
plain template literals**, not only drizzle `sql` tags | nothing; the
one miss probed was an identifier the schema never uses |
| `check-inert-sync-lane-conversions` | lane reads via the
`resolvePlannerLanes` helper | a **direct**
`store.resolveTaskWorkflowIrSync(...)` read feeding
`resolveLifecycleColumns` — inert by the same mechanism, untracked |
| `check-fnxc-future-dates` | future stamps | nothing — it caught this
table's author, twice |

## The two lessons the table encodes

**A ratchet's blind spot is invisible in exactly the way its subject
is.** Both fixed gaps sat next to a printed zero *and a sentence
promising nothing could land silently*. The count was true. The sentence
was true only for the forms the parser happened to visit. That is the
same shape as the conversions this program spent weeks finding — code
that looks converted because the instrument cannot see the difference.

**Probe correctness is its own trap.** The first census probe measured
nothing: the scanner enumerates git-tracked files, the probe was
untracked, and the scanned-file count staying flat reads *exactly* like
"no gap". A `DELIBERATE-LITERAL` probe likewise read as a broken escape
hatch until the marker moved to its own line — mid-expression it
attaches to the wrong node, which is the documented gotcha, and it still
caught the person who had just written it down.

## Reported, not fixed

The inert-sync gap is left open deliberately: it is one narrow shape,
the only in-tree instance (`replan-target.ts:95`) is documented, new
conversions would use the tracked helper, and that gate has uncommitted
work from another worker. Recording it beats editing a file someone else
is mid-change on.

```
lint clean; fnxc-future-dates: none added; all five gates --strict green on this tree

478b15d7ec docs(solutions): add the CI failure-rate method, and a fourth instance (#3244)
## What

Follow-up to #3243. That note said *"take a second measurement of a
different kind"* — true, and useless at 2am without the technique. This
adds the one that actually settled every case, plus a fourth instance
that occurred after #3243 was written. Docs only.

## The technique

Enumerate recent failing CI runs and compute a **per-file failure
rate**. Seven runs separated three populations that are
indistinguishable from a single local run:

| rate on CI | meaning | action |
|---|---|---|
| **7/7** | consistent, real | fix, or diagnose and hand off with
evidence |
| **1/7** | intermittent | flake or race; two in one subsystem is a
product-race smell |
| **0/7** (fails only locally) | environment | fix your sandbox, change
**nothing** in the repo |

Measured on this repo's main while writing it: `planning-browser-e2e`
**7/7**, `postgres/schema-applier` **1/7**, `report-store.pg` **1/7**.

## The fourth instance

#3243 documented three reversals. A fourth happened after it merged: a
component test with **2 failing cases locally, 0/7 on CI**. That makes
**three separate local-only failures in a single session** — a
model-routes test hanging offline, a component test with four failing
cases, and a set of assertions I was ready to call a regression.

Each felt like a finding. All three were my sandbox. That is frequent
enough to be a habit rather than bad luck, which is why it is worth a
row in a table rather than a mention.

## The cost asymmetry, which should drive the default

Acting on a **0/7** by quarantining **deletes coverage that is green
everywhere else**. Acting on a **7/7** by investigating costs an hour.
The errors are not symmetric, so when unsure which row you are in, the
cheap move is always more samples from the *other* environment — not
more confidence about the one you have.

This is the concrete form of the point the standing quarantine rule
already encodes with *"without a corresponding real bug"*: **"I saw it
fail" is not that clause**, and the failure-rate table is how you tell
the difference before acting.

```
lint clean; fnxc-future-dates: none added (exit code checked before piping)
```

5365746d37 docs(solutions): record "one sample is not a diagnosis" (#3243)
## What

A `docs/solutions` note recording three diagnoses I reversed **in one
session**, all wrong the same way. Docs only.

## The three

| observed | my story | what it was |
|---|---|---|
| `planning-browser-e2e` fails at width **769**, passes at **768** |
layout regression at the tablet breakpoint, from FN-8606 | a **race** —
5 passes in 6 runs; on every pass the control sits inside the viewport
at 769 (`right: 753 ≤ 769`) |
| a model-routes test fails **3 of 3** locally | red on main; quarantine
candidate | **green on CI**; a sandbox interaction. The fixture is
configured offline, so a sandbox should not have changed the outcome —
the tell was there from run one |
| one approach could not cover a resolver | the site is **unpinnable** |
a *different shape* covered it — a helper that **resolves** rather than
one that **receives** |

Each was plausible, mechanistic, and consistent with the evidence I had.
That is what made each dangerous: **a diagnosis that explains your one
data point feels finished.**

Each survived exactly until a second measurement **of a different kind**
— another environment, more samples, an instrumented probe. Re-running
the same command is not a second measurement.

## The reusable part

| observation | tempting story | check first |
|---|---|---|
| fails at boundary X, passes at X−1 | structural bug at the boundary |
run it 5 more times — boundaries are where races surface |
| **consistent** locally, green on CI | main is broken | the
environment; consistency is not universality |
| **intermittent** locally, consistent on CI | flaky test | a race the
slower runner loses every time |
| one approach failed | the site cannot be done | whether a different
*shape* of the approach works |

## Why it matters beyond debugging hygiene

Two of the three would have caused real damage if acted on:

- Quarantining the model-routes test — the action the standing rule
seems to license on "observed failing" — would have **deleted coverage
that is green everywhere else**. The rule's *"without a corresponding
real bug"* clause is load-bearing, and a local observation does not
satisfy it.
- "Unpinnable" hardened a single failed approach into a property of the
site. Left standing, it becomes a permanent excuse not to look — the
same failure I corrected in an inherited note earlier today, which had
recorded four resolvers as unmeasurable for environment reasons that did
not hold here.

Hence the last rule: **record cautions as environment-scoped, not as
properties of the code.** Say where you measured.

```
lint clean; fnxc-future-dates: none added (exit code checked before piping)
```

851369a480 docs(solutions): record "silence is not success" (#3241)
## What

A new `docs/solutions` note recording a failure that hit **three
different tools in one session**, each time reading as a pass. Docs
only.

## The three costumes

| what happened | looked like | was |
|---|---|---|
| `git stash --keep-index` swept the new test file out of the tree | "45
passed" | the pre-existing count; the new test never ran |
| a blinding script hit an unmapped role and `sys.exit(2)` **with no
message**; `&&` skipped the check, `;` let the run proceed | "375/375
green under blinding" | nothing blinded — run was against unmodified
source |
| a gate piped to `tail -1`, printing a blank line | "gate ran, no
complaints" | exit code 1; the FNXC stamp check had failed, and **CI
caught it in #3238** |

## Why it deserves its own note

**A passing run and a run that never happened produce the same evidence:
no failure text.** Every other bug announces itself; this one is defined
by the absence of an announcement. The instinct that catches ordinary
bugs — *"nothing looks wrong"* — is precisely the instinct that
certifies this one.

It gets worse under automation, where output is piped and skimmed. `|
tail -1`, `| grep "Tests"`, `>/dev/null 2>&1` all discard the part that
would have said `No test files found` or `command not found`.

## The five rules, each paid for above

1. **Assert the exit code before any pipe.** A pipeline's status is the
*last* stage's — `cmd | tail -1` reports `tail`'s success, never
`cmd`'s.
2. **Confirm the run did the work.** "Test Files 1 passed" when you
expected 16 is a finding, not a pass.
3. **A tool that can no-op must say what it did** — print the
substitution and location, fail loudly where it cannot act.
4. **Verify the mutation, not the tool's promise** — `git diff --stat`,
not the exit code.
5. **Break the guard on purpose once** and watch it fail. A guard never
observed failing has not been shown to work — the standard this repo
already applies to product ratchets, turned on your own verification.

## The uncomfortable part, kept in

The third instance was a rule **I added to AGENTS.md myself in #3174**,
broken for the second time. I ran the gate. I read `tail -1`. I moved
on.

Writing a rule down does not make you follow it. The only reason it was
caught is that **CI read the output when I did not** — an argument for
the gate existing, not for me having been careful.

Cross-linked from the resolver-audit note, whose every wrong reading
came from a run that never happened rather than from the blinding
itself. That connection is the point: I spent this session auditing a
program whose subject is defects hiding behind green results, and
reproduced the same class three times in my own tooling.

```
lint clean; fnxc-future-dates: none added (exit code checked before piping this time)
```

05f09c29f8 docs(solutions): complete the repo-wide resolver audit; correct a superseded note (#3236)
## What

Completes the repo-wide resolver audit and **corrects a note of mine
that had gone stale**. Docs only.

Every `resolveProjectColumnsForRoles` call site in the repository has
now been blinded individually.

## Final results

| package | sites | outcome |
|---|---|---|
| `engine` | 10 files | scheduler, triage, evaluator uncovered → pinned;
executor, restart-recovery, notification already covered; self-healing
21 pinned / 1 inert |
| `core` | 14 | 9 covered, **5 uncovered → all 5 pinned** (#3225, #3227,
#3233, #3234, #3235) |
| `dashboard` | 4 | `register-task-workflow-routes.ts:1268` covered;
`server.ts` ×3 flagged |
| `cli` | 1 | flagged |

## The correction

A note recorded `workflow-analytics.ts` and `team-analytics.ts` — 4
resolvers — as **unmeasurable**, because `pgDescribe` probes TCP and the
`.pg` suites skip without it.

The caution is real and stays: a skipped suite reads exactly like a
passing one. But on an environment where those suites **do** run, all 4
were measured, and `team-analytics.ts` turned out to have a half-covered
pair — `completeLanes` covered, **`activeLanes` not** — in a file named
`team-analytics-renamed-lanes`. That is now pinned (#3227, merged).

Left standing, the note converts a real finding into a **permanent
excuse for not looking**. It now says: confirm the suite actually skips
*here* before recording a site as unmeasurable for environment reasons.

## A fourth measurement failure mode — the opposite direction

The three already recorded all produce false *uncovered*. This one
produces false *covered*:

**A COVERED verdict needs a baseline.** The dashboard sweep reported 5
failing files under the global blind. **4 of them fail on clean `main`**
and have nothing to do with lanes — a docs-inventory test and a
model-routes test among them. Read as-is, that is four resolvers falsely
credited as covered. Only
`register-task-workflow-routes.awaiting-planning.test.ts` passes clean
and fails blinded, so it is the sole real detector.

Second time today a baseline changed a conclusion (the first found a
genuine red on main, #3229).

## Why 4 sites are flagged rather than pinned

- **`server.ts:1922/1923/1938`** — inside the `/api/health/reliability`
route closure. No route-level test exists, and the only way in is
booting `createServer(store)` behind a mock-the-world shell, which the
slow-test rule forbids. The alternative is a refactor to expose a seam —
its own commit, since moving code and changing behaviour do not ride
together. (A note already in this doc reached the same conclusion
independently; this confirms it by measurement.)
- **`cli/commands/task.ts:660`** — worth its own warning. Extracting a
pure helper and testing it **would look like coverage and would not
be**: blinding the resolver leaves such a test green, because the helper
*receives* the lane set rather than resolving it. The uncovered thing is
the resolve call, not the decision it feeds. Its sibling test file
already records the same limit honestly for `boardColumnsForDisplay`.

## Reported, not fixed: 4 pre-existing red dashboard files on main

`lazy-loaded-views-docs.test.ts` (AGENTS lazy-view inventory drifted —
24 actual vs 18 documented), `ResearchView.test.tsx`,
`planning-browser-e2e.test.ts`,
`register-model-routes-kimi-k3-supplemental.test.ts` — 7 failing tests,
all in the non-blocking suite.

I am not fixing them here: the lazy-views inventory is a curated list
other workers are actively adding to, and rewriting it mid-flight would
collide. Flagging so it is visible rather than silently absorbed into my
blind's noise.

01ab2400d0 docs(learnings): blinding measures the instrument you picked — rule 5, and where the measurement cannot be taken (#3222)
Extends `blind-the-resolver-to-find-uncovered-conversions.md` rather
than forking a second doc on the same technique.

## Rule 5: blinding measures the instrument you picked, not the site

A suite that never reaches the blinded site reports `0 failed` for the
same reason a covered one does. The outputs are identical. This produced
a **wrong answer twice in one sweep**, both times reading as a finding:

| blinded | suite run | said | actually |
|---|---|---|---|
| `reads.ts` ×3 | `search-excludes-renamed-archive-lane.test.ts` | 3
uncovered | that file unit-tests `liveSearchPredicate` and never runs
`reads.ts`; against `cold-storage-renamed-archive-lane.test.ts` one of
the three is covered |
| `server.ts` ×3 | `reliability-metrics.test.ts` | 3 uncovered | that
file imports `../reliability-metrics`; nothing executes the route at all
|

The `reads.ts` case is the one to remember, because **the misleading
suite was written for that exact conversion**. It proves the
collaborator honours a resolved set — which says nothing about whether
the caller passes one, and can never fail when the call site is blinded.
That gap shipped as a real hole and was closed in #3220.

Doc adds the cheap guard: make the blinded edit obviously fatal (`throw
new Error("x")`) and re-run. Still green means the suite does not reach
the site and the measurement is void.

## Where the measurement cannot be taken

Per #3212's stance that recording *why* something cannot be pinned is a
result, three groups are written down so nobody re-derives them:

- **No TCP PostgreSQL** — `workflow-analytics.ts` / `team-analytics.ts`
(4 resolvers) keep renamed-lane coverage in `.pg` suites. `pgDescribe`
probes **TCP**; `pg_isready` succeeding on a **Unix socket** is not the
same thing. I made exactly this mistake and reported PG as reachable one
round before correcting it — mistaking the two turns 4 skipped suites
into 4 false "uncovered" readings.
- **No injectable seam** — `reads.ts`'s incremental-sync scan composes
Drizzle conditions against `layer.db`. A test there asserts the query
built, not the rows excluded: green, and blind to the bug.
- **Logic inside a route closure** — `server.ts`'s three resolvers sit
in the `/api/health/reliability` handler, which has no route-level test.
The only harness in that package is a mock-the-world shell the slow-test
rule forbids; the alternative is a refactor to expose a seam, which is
its own commit.

## Census

206ff11874 docs(solutions): record the blinding audit's own failure modes (#3223)
## What

Extends
`docs/solutions/workflow-learnings/blind-the-resolver-to-find-uncovered-conversions.md`
with what this session's audit work paid for. Docs only — no code, no
changeset (internal doc).

## The main addition: the audit's own failure modes

**Every wrong reading this method has produced came from test
*selection*, not from the blind.** Three in one session, each of which
reads exactly like coverage:

| what I ran | why it lied |
|---|---|
| `vitest run src/__tests__ -t "executor"` | `-t` filters test
**names**, not files. Reported two `executor.ts` resolvers uncovered;
**both are covered.** |
| `blind3.py <file> <var>` with an unmapped role | exited non-zero
**silently**; `&&` skipped the check and `;` let vitest run against
**unmodified source**. Reported "375/375 green under blinding" with
nothing blinded. |
| `vitest run src/__tests__/notification` | missed
`src/notification/__tests__/` — a nested `__tests__` the glob never
reached. Reported covered code as uncovered. |

The rule that follows: an UNCOVERED verdict is a claim about the whole
tree and needs the whole tree's tests. Confirm the blind actually
modified the file with `git diff --stat` — *not* the tool's exit code —
and that the run included every file importing the module.

I am documenting my own instrument failing the standard I have been
applying to product guards all phase: *a guard that reports success
without checking anything is worse than no guard.* Mine reported success
without checking anything. It now echoes what it substituted and where,
and fails loudly on an unmapped role or missing variable; I self-tested
both directions before trusting any number in #3219 and #3221.

## Rule 5: the resolver must be able to answer differently in the
harness

`resolveProjectColumnsForRoles` returns **legacy ids and nothing else**
when the store has no `listWorkflowDefinitions` — an intentional degrade
so an unreadable workflow list cannot fail a sweep. A harness omitting
it makes the resolved set and the literal set **equal by construction**,
so the conversion is unobservable however good the assertion is.

This is not a test bug. It is correct production behaviour that erases
the difference the test is trying to measure — and it alone left both
the `scheduler.ts` and `triage.ts` conversions unpinnable.

## A correction to my own earlier rule

I had "seed-then-union sites hide defects" too broad. Such a site hides
a defect **only while every lane you assert on is already in the seed**.
On a renamed board the resolver is the sole contributor of the renamed
lane, so the legacy blind is *not* a no-op — I predicted it would be and
it failed. Also: expand roles to legacy ids **per role** from
`LEGACY_COLUMN_IDS_BY_ROLE`; `intake` is `["todo","triage"]`, not
`["triage"]`, and a stricter-than-real blind manufactures failures that
read as coverage.

## Inventory, so the gap is legible

**116 non-test call sites across 30 files** — core 17, engine 10,
dashboard 2, cli 1. Audited so far, all in engine: `self-healing.ts` (64
mapped / 21 pinned / 1 inert by construction), `executor.ts` (2,
covered), `scheduler.ts` (uncovered → pinned in #3219), `triage.ts`
(uncovered → pinned in #3221), `restart-recovery-coordinator.ts`
(covered), `notification-service.ts` (covered).

**`packages/core`'s 17 files are entirely unaudited.** Stated as a gap
rather than left implied, so nobody reads engine's coverage as a
repo-wide clean bill.

## Flagged, not guessed

- `evaluator.ts`'s archived read is uncovered — **no test file imports
that module at all.** Left unpinned deliberately: it is a thin
pass-through into `collectDeterministicSignals`, which is testable
directly, and it affects eval signal quality rather than task lifecycle.
Recorded in the doc rather than silently skipped.
- I did not audit core; it is outside my package and I am not claiming
anything about it either way.

2868eb4797 docs(learnings): blind the resolver to find uncovered conversions (#3214)
Sibling to #3203 (`a-falling-count-is-not-evidence`), which records that
a metric moving is not proof the system moved. **This is the positive
procedure**: how to find out whether a landed conversion is held by
anything, and how to write a test that holds it.

## The measurement it is written from

Of **64 resolved lane sets in `self-healing.ts`, 26 had no test that
could distinguish them from the literal they replaced** — including
three conversions I shipped that same day, and two halves of sweeps I
had already recorded as covered.

## The procedure

```
- const reviewColumns = await resolveProjectColumnsForRoles(this.store, REVIEW_ROLES);
+ const reviewColumns = new Set<string>(["in-review"]);
```

Suite fails → covered. Suite passes → nothing in the tree can tell the
conversion from the literal. One resolver, one 17-second run — cheaper
than writing the conversion was.

## Why the census cannot answer this

| instrument | question |
|---|---|
| census / lane-wiring ratchet | is this site written in the resolved
vocabulary? |
| blinding | does anything break if it stops being? |

Neither substitutes for the other. A conversion merged with 204 green
tests behind it and zero able to see it.

## Four rules, each paid for by a test that proved nothing

1. **Blind each resolver separately** — coverage is per-resolver, not
per-sweep. Twice a sweep recorded as done was half-done, because control
flow short-circuited before the second guard.
2. **The fixture must reach the branch the resolver gates.** A card in a
renamed *wip* lane cannot exercise a *terminal* skip — it is caught by
the wip∪review set first.
3. **Assert a path-specific side effect, never a return value.**
`outcome === "reclaimed"` is reachable without the guarded branch.
4. **A store fake must honour `options.column`.** Flat and call-order
stubs answer identically whatever column is requested — a fake that
ignores its own filter cannot see a filter bug.

## The two shapes a ratchet cannot distinguish

- **resolved gate, literal branch** — reads as *unwired*, was a live
defect (#3208: a working agent lost its task link)
- **passed-but-unread** — reads as *wired*, is dead code (#3212)

A ratchet counting call sites scores the first as debt and the second as
done. Both wrong.

## Why a doc and not more PR comments

Everything above currently lives in ~20 PR descriptions. The next person
to touch a lane conversion will not read those. `docs/solutions/` is
where this project already keeps the things it learned the expensive
way, and the frontmatter (`applies_when: deciding whether a lane
conversion is actually protected by a test`) is what makes it findable.

## Verification

`pnpm test:gate` 13 + 161 + 499 + 71 · lint · fnxc-dates (TZ=UTC) ·
`self-healing-docs` 2 passed. Docs only; no changeset, per the AGENTS.md

e9a57ca8ba docs(learnings): a falling count is not evidence that anything changed (#3203)
## The metric counterpart to #3200

#3200 (merged) records the **shapes** an inert conversion takes, and its
grammatical tell is the portable one: *if a claim can be written without
running anything, it has not been tested.* I offered this material there
and said I would write it as a sibling rather than bloat that doc; it
merged without it, so here it is.

That doc is about **claims**. This one is about **numbers**.

## The tell

**A count that falls is not evidence that anything changed.** Every gate
here reports a number, and a number goes down three ways — work
happened, the code got denser and the scan stopped matching, or someone
lowered the allowance. Only the first is progress, and from inside the
check all three look identical.

Four times in one phase:

| what moved | what actually happened |
|---|---|
| census 12 → 2 (`scheduler.ts`, #3051) | ten guards routed through
`resolveTaskWorkflowIrSync`, which answers with the DEFAULT board under
PostgreSQL. Byte-identical. Refuted in #3058 |
| census 45 → 44 (`triage.ts`, #3114) | converted the exact arm #3108
flagged hours earlier. #3126 reverted it — three PRs for one line |
| ratchet 20 → 15 | not a conversion: #3065 rewrote `a === x \|\| a ===
y` as `set.has(a)`. It printed *"total fell — re-record"*, which would
have **permanently retired live guards** |
| ratchet 22 → 9 | `scheduler.ts` reported **0** while 13 guards still
fell back to the default board |

Rows three and four are the dangerous shape: **the gate went quiet
exactly when someone improved the code**, and the remedy it suggested
was to lower the allowance.

## Also recorded

- **One defect, four spellings** (#3062, #3068, #3079, #3181) — each fix
correct about the shape in front of it and blind to a respelling. The
lesson is not "write a better regex": enumerating consuming syntax is a
losing game, and the durable form keys on the *source*.
- **An instrument that runs nowhere and one that cannot fail are the
same defect.** `check:inert-sync-lanes` was invoked by nothing for six
PRs; `check:quarantine-ledger` ran nowhere *and* omitted `--strict`, so
wiring it alone would have been theatre. Includes the mechanical audit
that finds both.
- **Base drift makes branch numbers incomparable** — three false alarms,
one of them mine, from comparing against a remembered figure. The
procedure that works is extracting both scripts and running them against
one tree; that is how #3169 and #3181 were shown additive (22 = 13 + 7 +
2), which decided merge order and collapsed one into six lines inside
the other.
- **A pick-work list at 100% false positives**, because under-reporting
deferrals is the direction that manufactures the #3108 → #3114
collision.

## Every claim is a measurement

No mechanism here is derived from reading. Nine PRs cited, each the one
that produced or refuted the finding — including the ones where I was
wrong: a stale number I mistook for a regression, and two future-dated
stamps of my own that the full ratchet set caught before they shipped
(one earlier one it did not, and that broke `main`).

## Census before / after

```
before:  COLUMN guards (the backlog):   12
after:   COLUMN guards (the backlog):   12
```

## Verification

`test:gate` exit 0 · `fnxc-future-dates`, `lifecycle-columns`,
`inert-sync-lanes`, `quarantine-ledger`, `inert-flag-seams`,
`lane-wiring`, `sql-column-literals` — all exit 0 · `pnpm lint` clean.

5f97fbcb06 docs(learnings): a blocker described four times, wrong twice — instrument before you file (#3200)
Records the method that moved a `triage.ts` site flagged unconvertible
for four cycles. The method transfers; the three conversions do not.

## Four mechanisms, split by derivation rather than care

| # | claimed mechanism | derived from | held? |
|---|---|---|---|
| 1 | merged intake/hold vocabularies | reading | no |
| 2 | orphan arm scoped to `source === "selection"` | reading + one test
run | partly |
| 3 | provenance verifies by `ir.id`, which builtins lack | reading a
**comment** | **no — filed as #3187, closed as wrong** |
| 4 | two test harnesses cannot answer a selection query | instrumented
isolation | **yes** |

(3) is the expensive one. The text I quoted was **historical prose
describing code that had been removed**, sitting directly above a
paragraph saying exactly that. I read a rationale as an implementation,
and it reached an issue other lanes could have acted on.

## The isolation took three runs

```
flag only, no conversion             8 passed   -> the orphan arm is not the cause
flag + conversion                    5 failed   -> the conversion is
same, with a realistic mock store    8 passed   -> the mock was the cause
```

Change one variable, let the suite answer. Available from cycle one.

## Why this is not just "test more"

Every wrong mechanism was plausible, specific, and consistent with the
code as read. **Plausibility is what made them dangerous** — each was
good enough to write down, publish and act on. The failure mode is not
sloppiness; it is that a careful reading of a large file *feels* like
evidence.

The tell is grammatical: **a claim that can be written without running
anything is a hypothesis, not a measurement.** "This cannot be converted
because X" versus "reverting X fails these 3 of 8 cases."

## The corollary, including its negative result

Once the harness was the suspect, a class fell out: a test that stubs a
reader **broken in production** proves the call site's logic while
unable to see that production resolves nothing. Eight files stubbed
`resolveTaskWorkflowIrSync` — one masking a live defect, four redundant
(#3198), one legitimate.

The doc also records that the obvious generalisation **fails**:
`getTaskWorkflowSelection` is equally degraded under PostgreSQL but
stubbing it masks nothing, because the resolver prefers the async twin
and both answer the same. The distinguishing property is that the reader
returns something *incorrect*, not merely *unused*. Written down so
nobody repeats the 120-file sweep.

Docs only; `check-fnxc-future-dates` exit 0.

984b3ed0c1 docs(learnings): a seventh inert shape — reusing an already-resolved local (my #3114 turned main red) (#3130)
Records the failure shape behind #3126, from the person who caused it.

## What is new about it

The three inert conversions this program had catalogued — #3051, #3062,
#3068 — all called `resolveTaskWorkflowIrSync` **at the call site**,
where the sync resolver is visible in the diff. That is what the
existing entries describe, and it is why they read as avoidable.

Mine was not that. #3114 converted a `triage.ts` arm to
`disposeLanes.wip`, reusing a value `resolvePlannerLanes` had produced a
few lines above. It merged, and `main` went red: `triage.ts: 7 -> 8`.

My reasoning at the time, verbatim from the PR body:

> `resolvePlannerLanes` already called immediately above — no new
resolution/await.

That sentence checks the **cost** question and skips the **correctness**
one. I confirmed I was not adding an `await` to a synchronous listener —
the usual blocker, and a real one — and never asked what kind of
resolver had produced the local I was reusing.

**Reusing an already-resolved value reads as strictly safer than
resolving.** No new work, no new await, no new failure mode. That
intuition is correct about cost and silent about correctness, and the
sync-ness sits one hop away inside the helper, where a call-site
reviewer does not see it.

So the check is not *"am I calling a sync resolver here?"* but **"what
produced every lane value I am about to compare against,
transitively?"** A local is not evidence; the resolver behind it is.
#3122 widened the gate to follow wrappers for precisely this reason —
and I walked through the door it was widened to cover, during the same
phase I was adding it.

## Two corollaries recorded with it

1. **A gate that catches the defect but does not block is a report.**
`check-inert-sync-lanes` fired correctly and the PR merged anyway,
because it is not in the blocking set. #3127 fixes that, and I would
prioritise it over any individual conversion — this is the second time
this phase a correct non-blocking signal was ignored.
2. **`triage.ts`'s remaining 7 are not backlog.** The revert takes it to
7, and those seven are the same shape: they need the emitter-side /
async-threading work tracked in #3082, not another conversion pass.
`--claims` (#3124) now marks sync-resolver files as inert-risk and keeps
them out of the start-here list for exactly this reason.

## Scope

Docs only — one section appended to the existing learnings file, placed
with the other numbered shapes and before "The rule that produced every
fix above". No code, no gate, no changeset (internal docs).

The revert itself is #3126, which I confirmed on a clean detached
`origin/main` checkout rather than on a branch; I did not open a
competing fix.

20e3731eb1 docs(workflow-learnings): a deferral's stated blocker is a claim, and it decays like a measurement (#3026)
Two pieces of work were filed rather than fixed in one session, each
with a specific technical reason. **Both reasons were wrong**, and in
both cases the real obstacle was smaller than the stated one.

| filed rationale | reality |
|---|---|
| "the plugin has no scaffolding for faking its stores" (#3020) |
`_harness.ts` builds a real `PluginContext` over a live PostgreSQL
layer; the gap was **two missing readers on a stub** — fixed in #3022 |
| "supplying this needs a published-API change" (#3003) | the type is
dashboard-internal, `@fusion/plugin-sdk` is `private: true`; the actual
obstacle is stale type declarations between two in-repo packages |

The first one matters most: the filed issue was a **pipeline that stalls
forever** on a renamed board. The cost of that excuse would have been a
real stall sitting open behind a plausible-sounding note.

## The shape

Both times the blocker was asserted **from the shape of the problem**
rather than tested. *"This needs infrastructure that doesn't exist"* and
*"this crosses a published boundary"* are each checkable in about five
minutes, and neither was checked before I wrote a paragraph explaining
why the work couldn't proceed.

## Why it's worth writing down

Filing is often right — someone else owns the contract, the fix needs a
decision, the data genuinely isn't there. What makes it wrong is filing
on an **untested** blocker, because a filed issue with a confident
rationale is the one thing nobody re-derives. It reads as settled.

That's the same mechanism as a stale "do not re-probe" note (which this
document already records, and which I had to correct in #3018), one
level up: there a *measurement* went stale, here a *decision* did.

## The rule

**Before writing the blocker down, spend five minutes trying to hit
it.** If it's real you'll hit it immediately and can describe it
precisely — which makes the issue more useful. If it isn't, you have the
fix instead of the issue.

eecc87c31e docs(workflow-learnings): the "named legacy-id collections are clean" entry was wrong (#3018)
It hid two real defects — and it explicitly told the next reader not to
re-probe them.

## What the entry did

Counted **declarations** (48, then 49) and concluded the population was
benign because each one is a fallback vocabulary, a builtin column list,
or an already-converted seam.

All true of the declarations. **The declaration isn't where the defect
lives.**

## Measure the use, not the declaration

A collection used as a **membership gate against a column**. Nine exist,
and two were live user-visible defects sitting inside a population this
doc had marked clean:

| site | defect |
|---|---|
| `TIME_INDICATOR_COLUMNS.has(task.column)` — `TaskCard` | elapsed-time
indicator never rendered on a renamed board (#3014) |
| `PLANNER_ACTIVITY_COLUMN_IDS.has(task.column)` — `useTasks` | planning
border and pulsing badge never appeared (#3017) |

The other seven are genuinely fine, and the reasons are kept because
they're the shapes worth recognising: the no-flags fallback *inside* a
role helper, a seam that seeds the legacy pair then unions resolved
lanes, a marked `DELIBERATE-LITERAL` fallback chain, and a plugin with
no trait source at all.

## The tell

One question separates the two groups: **does a flags path exist in this
file at all?**

Both defects had none — the gate was the only decision, with nothing to
degrade from. Every benign case had a resolved path sitting right next
to the literal.

## Why this is worth its own PR

A "do not re-probe" note that is wrong is **worse than no note**: it
converts one person's incomplete measurement into everybody's blind
spot. That's the same failure this document already records for
`sortTasksForDisplayColumn`, one level up — there an annotation told
readers to skip a *row*, here it told them to skip a *population*.

I wrote the original entry, and I'd read past it twice myself before
#3014 forced the re-measurement.

e9f587c363 docs(workflow-learnings): correct the "bounded" heuristic — a clock-shaped dep is not a fast one (#3012)
The severity heuristic I wrote in #2998 sorted dependencies **by name**,
and #3007 is the counterexample.

## What I got wrong

I classified `lifecycleDates` as *bounded* because its dep list contains
`lifecycleNowMs`, and deferred it in #3001 with the line *"any wrong
answer there survives only until the next update."*

That value is driven by a **local-midnight boundary timer** — one tick
per card per day. So a finished card shows no completion date for up to
**twenty-four hours**. @gsxdsm found it after I'd written it off.

`nowMs`, `Ticker` and `lastFetchTimeMs` span a live 30-second ticker, a
per-fetch stamp, and a daily boundary. Sorting them by name puts a
day-long defect in the same bucket as a 30-second one.

## The sharper half

A card in a **completion lane doesn't subscribe to the shared live
ticker at all** — that's exactly what the ticker's eligibility check is
for, and what #2996 fixed. So the "fast" dependency that would have
rescued this population is the one thing that population never receives.

The corrected question is: **which dependencies refresh *for this
population*** — not which ones appear in the list. Two of my three
severity calls in that sweep leaned on a dep that the affected cards
structurally never get.

## Why this is worth a PR rather than a quiet edit

The doc is what the next person triages against. #3001 explicitly told
them the four "bounded" sites were deprioritised **by design** — on
reasoning that was wrong for at least one of them. Leaving that in place
means someone defers a day-long defect on my say-so.

e78bf20d55 docs(workflow-learnings): a sixth shape — the resolved value arrives after a memo has answered (#2998)
## The shape

Three defects this session, all the same, none visible to any instrument
here:

A lane value resolved **asynchronously** (the board fetches workflow
traits after first paint) is read inside a `useMemo`/`useCallback` whose
dependency list omits it. The first computation runs with the flags
`undefined`, the role helpers correctly fall back to legacy ids, and on
a **renamed** board that answer is wrong. When the flags arrive nothing
in the dep list changed, so the memo never recomputes.

| defect | severity |
|---|---|
| blocker fan-out trait index (#2993) | permanent — empty index for the
mount |
| card live elapsed-time indicator (#2996) | permanent — never
subscribes |
| near-duplicate chip (#2997) | bounded — self-heals on the next task
refresh |

A legacy board hides all three: there the fallback already answers
correctly on the first paint, so the stale list costs nothing. **Every
instance is renamed-board-only**, which is why they accumulated — and
this repo has no `react-hooks/exhaustive-deps` rule, so the class is
invisible to lint.

## Two properties decide severity, both readable off the dep list

1. **Does any dependency refresh quickly?** `allTasks`, a live clock, a
task identity — any of them rebuilds the closure on the next update,
making the wrong answer a bounded window. The chip keys on `allTasks`
and recovers; the indicator keys on `task.column`, which never changes,
so it never does.
2. **Is the value covered transitively?** A dependency that itself lists
the flags gets a new identity when they arrive, and that propagates.

## A gate was built and rejected — the part worth writing down

The scanner reports **19 sites; two were real.** Property 2 is why:
transitive coverage is invisible to any purely syntactic check and would
need a real dependency graph.

`TaskCard`'s context-menu memo omits all three role flags and is
**nonetheless correct** — it depends on `taskActionMenuModel.actions`,
and that model lists `taskColumnFlags`, so the whole chain recomputes. I
checked that before filing it, which is the only reason this PR isn't a
bug report about missing Archive/Revert menu entries.

Freezing 19 would have baselined mostly noise and trained everyone to
skip the report — the exact failure this document already records for
`sortTasksForDisplayColumn`, where an annotation saying "ignore these"
hid a real defect for days. **A good investigative tool is not
automatically a good ratchet**, and the next person deserves to know the
turn was considered rather than missed.

The triage that does work is cheap: run the scan, then ask the two
questions above. Nine of nineteen survive question 1; hand-checking
those is an afternoon, not a project.

Docs only — no code, no baselines.

6a465e1006 docs(workflow-learnings): probe harnesses lie more often than the gates do (#2983)
## What

Probing four gates with unimagined shapes this session (#2979, #2980,
#2981) produced **two rounds of silently invalid results** — both from
the harness rather than the instrument, and both agreeing with what I
expected, which is why neither was noticed on the spot.

1. **`node gate.mjs | tail` then `echo $?` reads *tail's* exit status.**
Every probe reported "caught". The gate was in fact failing on `main`
for an unrelated reason, so the runs proved nothing. That fictional
evidence nearly shipped a double-counting change to the SQL gate.
2. **A gate that lists files with `git ls-files` cannot see an untracked
probe file.** Six census probes reported "missed" — including the shape
the census is explicitly built for, which was the tell.
Filesystem-walking gates (`check-sql-column-literals`,
`check-inert-flag-seams`) see untracked files; the census does not.

The rule that catches both in one step, now written down:

> **A probe run needs its own control.** Include one shape the
instrument is known to catch and one it must not flag. If the known-good
shape doesn't come back caught, stop — you're measuring your harness.

Worth stating plainly because the two failure modes have opposite costs:
a probe that wrongly reports *caught* retires a real hole; one that
wrongly reports *missed* sends you rewriting an instrument that was
already correct.

## Two measured negative results, recorded so nobody re-runs them

Added to the existing "Surfaces that were checked and are CLEAN"
section:

| shape | population |
|---|---|
| `switch (task.column)` with legacy `case` labels | **0 sites** |
| a legacy id hoisted into a single const, then compared | **1 site —
and it is correct code** |

The one site is `self-healing.ts:2992`, which seeds `let holdColumn =
"todo"` as its documented legacy floor and then overwrites it from
`resolveLifecycleColumns(...).hold`. The census is right not to flag it;
a naive version of this probe reports it as a defect.

The second shape was worth measuring precisely because **the same shape
had a real population in SQL** — it's what #2980 fixed. It did not
transfer. Population is a property of how people write that particular
kind of code, so each instrument has to be measured on its own rather
than by analogy to a sibling that just turned something up.

## Why this is docs and not a gate change

The census's comparison-only scope is adequate for this codebase: every
blind shape I could construct has an effectively empty real population.
Demanding new detection would have forced a large baseline change across
the program's central instrument for **zero defects** — the same mistake
as filing "48 uncounted sites" that the existing section already warns
about.

Docs only. No code, no baselines touched. All five gates green.

b1bd571682 batch-sql-ratchet: the census / gate-ratchet family — collection branch, fold here (#2941)
## Family branch for consolidation directive item 4

`batch-sql-ratchet` did not exist and ~10 open PRs are waiting for a
collection point, so this establishes it. **Fold your census/ratchet
commit here and close your own PR as superseded.**

```bash
git fetch origin batch-sql-ratchet
git checkout -B batch-sql-ratchet origin/batch-sql-ratchet
git cherry-pick <your-sha>
# verify scoped, not full suite:
pnpm --filter @fusion/core exec vitest run src/__tests__/archived-column-gate-parity.test.ts --silent=passed-only --reporter=dot
git push origin HEAD:batch-sql-ratchet
```

**Candidates I can see open right now** (owners: please fold + close):

| PR | branch |
|---|---|
| #2938 | `fix/comments-ops-sentinel` |
| #2935 | `fix/task-artifacts-sentinels` |
| #2933 | `chore/commit-tightened-census-baseline` |

| #2921 | `fix/plugin-store-migration-marker` |
| #2894 | `gate/sql-literals-match-census-placement` |

That is **10 → 1** once folded. I have not cherry-picked anyone else's
commits — folding someone's work without them verifying it is how a
batch lands broken.

---

## What is in it so far (mine, from #2924)

**Clears a live main red:** `archived-column-gate-parity` fails on
`origin/main` today.

```
AssertionError: TypeScript encoding changed.
  async-comments-attachments.ts: 8 → 5
```

#2886 fixed a real bug — archived-document guards failing in *opposite*
directions on a renamed lane — by replacing three `column ===
"archived"` comparisons with `isArchivedLane(column, archivedColumns)`.
The AST scan counts raw comparisons, so the tally dropped.

**What I did not do is record it as three sites converted**, because
measured, it is not:

```
grep -rn "archivedColumns:" packages/core/src packages/engine/src --include="*.ts" | grep -v __tests__
→ (no matches)
```

No caller passes it. The parameter defaults to `LEGACY_ARCHIVED_LANES =
new Set(["archived"])`, so every call resolves to the literal it
replaced — byte-identical behaviour, resolved branch dead.

That matters for this guard's whole argument: its header warns that
converting the TypeScript half while the Drizzle and raw-`sql` halves
still compare the string is a split brain *"no test would catch, because
every builtin workflow spells the column `archived` so the two halves
agree by accident on every board we ship."* **There is no split brain
today precisely because the resolved half is unwired** — it becomes one
the moment a caller threads real lanes in without the SQL sides moving.
Recorded inline so `5` cannot be read as "3 sites done"; flagged on
#2886.

Verified not a split brain: the Drizzle and raw-sql inventories are
unchanged and both pass — worth stating because those assertions run
*after* the TypeScript one, so a plain red says nothing about them.

Scoped edit to `AUDITED_TS_SITES` by line range: these paths appear in
more than one inventory here, and an unscoped replace would quietly edit
the raw-sql side too, making the parity guard agree with itself (the
trap I hit in #2817).

Guard still bites: appending a real `task.column === "archived"` to an
audited file fails it. Core **4852 passed / 0 failed**, lint clean,
test-only.

Closing #2924 as superseded by this.

7b68f20501 batch(docs): fold the three workflow-learnings / annotation PRs into one (#2942)
## Family batch — replaces #2926, #2892, #2887

Per the consolidation directive: the u9/e2e **docs family**, folded into
one branch and one CI run. Three PRs, five commits, **five files,
comment and markdown only**.

| folded PR | commits |
|---|---|
| #2892 `docs/union-vs-per-task` | the project union and the per-task
answer are not ranked; date correction |
| #2926 `docs/date-my-measured-claims` | date the measured claims (one
was wrong); date the grep-vs-AST measurement in the SQL gate header |
| #2887 `docs/archived-state-literals` | mark the three archived STATE
literals as deliberate |

Cherry-picked in original order with authorship preserved; all five
applied clean, no conflicts.

## Scope is provably comment-only

```
docs/solutions/workflow-learnings/lifecycle-conversions-that-score-as-wins.md
docs/solutions/workflow-learnings/project-union-versus-per-task-lanes.md
packages/core/src/task-store/async-maintenance.ts        ← FNXC DELIBERATE-LITERAL annotation
packages/core/src/task-store/workflow-definitions.ts     ← FNXC DELIBERATE-LITERAL annotation
scripts/check-sql-column-literals.mjs                    ← header prose only
```

Every added line in `packages/` and `scripts/` is inside a comment —
checked by filtering the diff for declarations, conditionals and
returns, which returns nothing. The two core files gain
`DELIBERATE-LITERAL` markers explaining that `'archived'` is a **state**
marker there, not a lane: the sweep collects rows Fusion itself archived
or soft-deleted, so widening to the resolved archived set would pull
live cards into a cleanup pass.

## Verification (scoped, per the directive — not the full suite)

- `pnpm lint` — clean
- `check-sql-column-literals` — exit 0 (the file it annotates)
- `check:lifecycle-columns` — exit 0 (the markers it adds are
census-visible)
- `sync-workflow-ir-callsite-allowlist.test.ts` — 3/3

## A correction worth recording

Mid-fold I saw a changeset, `self-healing.ts` and a test file in `git
diff origin/main..HEAD` and nearly reported the batch as impure. They
were **main's own commits** — `origin/main` advanced between branch
creation and the diff, so the comparison was against a stale base.
Rebasing onto current `main` reduced it to the five files above. Worth
flagging for anyone else folding a family today: with `main` moving this
fast, diff the branch **after** rebasing or the file list will lie to
you.

## Closing the originals

#2926, #2892 and #2887 are superseded by this and are being closed. I
hold no PRs of my own in this family — all mine merged — so this fold is
on behalf of the family rather than a rollup of my own work.

5792452f0a docs(workflow-learnings): mutation testing has one blind spot — your own imagination (#2858)
The most transferable thing this lane produced, and it is a correction
to advice I wrote earlier in the same document.

## The gap

Every other section here says *"watch the guard go red before you trust
it."* That rule is necessary and **not sufficient**, and the way it
fails cost the most.

Three instruments were written during this program. Each was
mutation-tested in both directions before shipping. Each was green.
Reviewers then found, in those same instruments:

- a **file-level pre-filter** that skipped whole files, so a forbidden
site added to a file with no other SQL was invisible;
- an **anchored pattern** that missed qualified and compound fragments
(`t."column" = 'done'`);
- a scan over **SOURCE text**, where a double-quoted TS string still
spells `\"column\"` with the backslashes in it;
- an operator list of `= != <>` that never considered **`IN (...)`**;
- and worst, a template scan that joined only the **static spans** — so
a Drizzle query, which puts the COLUMN in the interpolation hole and the
legacy id in the static text, matched nothing. **That gate was blind on
the exact files it was built to freeze.** Enabling that one shape took
the population from 14 to 31 and revealed five previously invisible
files.

## Why the mutation tests could not catch any of them

All five are **false negatives**, and the reason is structural rather
than sloppy:

> A mutation you write is a mutation you already imagined, so it lands
inside the space your scanner understands.

Reintroducing a defect the checker was designed around proves the
checker still handles that defect. It says nothing about shapes you
never modelled.

## What does find them

1. **Run the instrument against the code it was written for and read the
hits by hand.** The Drizzle blindness was obvious the moment someone
asked *"why is the merge-queue query — the reason this exists — not in
the output?"*
2. **Prefer one unanchored pattern over a fast pre-filter plus a precise
one.** Every false negative above came from two patterns disagreeing
about whether to run the real check at all. A pre-filter is a second,
weaker specification of the thing you are testing.
3. **Treat a guard's own count as a claim to verify, not a result.** "14
sites" read as coverage for days; it was the subset one scanner happened
to model.

A false positive is loud and gets fixed. **A false negative prints a
baseline and reads as coverage.**

Docs only — no changeset.

be12ca905b docs(workflow-learnings): the fifth shape — converted consumer, literal-passing producer (#2835)
Found by the operator reviewing **my own** shipped fix (#2823). It
belongs in this document because it is the only shape so far that every
instrument in the program reported as done.

## The defect

`clearNearDuplicateReferencesTo` was converted to resolve the
canonical's column flags, and my test proved that by supplying `column:
"shipped"`. Both production call sites in `moves.ts` gated on the
**resolved** complete lane and then passed the literal `column: "done"`.
The consumer was correct; the producer was never converted; and the
hand-supplied fixture value is exactly what hid it.

Why nothing caught it:

- the **census** counts comparisons — a value passed as an argument is
not a comparison;
- the **seam check** asks whether callers *supply* the argument — these
did, with a literal;
- the **test** supplied the interesting value itself, so it exercised
the consumer and never the producer.

And the part I would have got wrong: driving the flow end to end still
does **not** distinguish them. The consumer looks the passed column up
in the canonical's IR, finds nothing for `done` on a renamed board, and
falls through to the legacy predicate where `done` *is* terminal — right
answer, wrong reason. It only bites on a board that declares a `done`
column **without** the complete trait.

## The rule

> A differential test must vary the value the **production** code
computes, not one the test hands in.

If the fixture passes the lane name, it has tested the consumer. Who
computes that argument in production, and do they compute it or spell
it, is a separate question — and the one that was wrong here.

## Measured, so nobody builds the wrong instrument

An AST probe for call arguments shaped `{ column: "<legacy id>" }` finds
**79 sites** across `packages/`. It correctly flags the two real
`moves.ts` offenders — but most of the rest are legitimate: `set({
column: "archived" })` writing the archive state, `listTasks({ column:
"todo" })` filtering a query.

So a blocking gate on this shape needs a curated list of consumers that
interpret a column as a **role**, as opposed to storing or filtering it
— a per-consumer judgment call, not a mechanical check. **Recorded
rather than built**, and deliberately not attempted on top of five
unmerged PRs in packages I do not own.

I also verified one nearby call site that a naive version of this probe
flags and which is **not** a defect: `archive-lifecycle-2.ts:353` passes
`column: "archived"`, but that path sets `task.column = "archived"`
unconditionally, so it is passing the column the card actually reached.
Exactly what the operator's fix is about.

Docs only — no changeset.

ba40942a10 batch-dashboard-app: 75 → 2 across packages/dashboard/app — the last two are deliberate, not missed (#2772)
**Batch branch is live: `batch-dashboard-app`.** Push conversions here
as commits rather than opening per-file PRs — that is the CI-run
bottleneck this model removes.

**One-line ownership note for you to arbitrate:** you have addressed me
as U11, U12 and U7 at different points, so the `u12 worker ->
batch-dashboard-app` mapping is ambiguous from my side. I claimed it
because `dashboard/app` is where I have done the most work this session
(TaskContextMenu, Column, TaskCard, TaskDetailModal, columnRoles,
taskActivity) and I know which of its guards are load-bearing fallbacks.
**If another worker is the intended owner, say so and I will hand the
branch over rather than both of us pushing to it** — two workers on one
shared branch is exactly what silently discarded a reviewed fix in #2645
today.

## The work order (measured at branch point, tests excluded)

**75 guards across 32 files.** Largest: `TaskContextMenu.tsx` 9 ·
`Column.tsx` 7 · `ListView.tsx` 6 · `TaskDetailModal.tsx` 4 · then a
long tail of 3s, 2s and 1s. Full per-file list is in the committed work
order so feeders can claim without re-measuring.

## Two rules this surface keeps tripping on

**1. A literal after `??`, or in the `else` of a `flags ?` ternary, is a
DEGRADED-MODE answer — not an unconverted guard.** Two real states reach
it: the **pre-load window** (board renders before the workflows fetch
resolves) and a card stranded on an id its workflow no longer declares.
In both, `columnFlagsById` has no entry at all. Deleting the fallback
does not remove a decision — it substitutes "no role" silently, and
affordances vanish during first paint.

Those sites reach 0 by **marking**, not deleting. Expect
`TaskContextMenu.tsx` and the `utils` files to be **mostly marks**. A "9
→ 0" that deleted 9 fallbacks is a regression wearing a green census.

**2. A marker excuses ONLY the construct it is attached to** — the
statement or function holding the literal, not a sibling declaration.
This has cost three passes, two of them mine; my first attempt on
`reliability-metrics.ts` scored **1 of 6**. **Verify by the count
moving, not by the comment existing.** With the ratchet gate-blocking, a
mis-marked batch either wedges the gate or locks the miss into a
re-recorded baseline.

## Status

Opening commit is the work order only — **0 of 75 converted so far.** I
am near the end of my context, so I am establishing the branch and the
shared list rather than starting conversions I cannot finish cleanly.
Feeders can begin immediately; I will keep the branch rebased.

My other PR **#2762** (`live-agent-count.ts` 6 → 0) is green and
unconflicted — per your rule it should land rather than fold into a
batch, and it is `packages/core` so it belongs to batch-core anyway.

## Late addition: the seam gate was masking a real offender

`scripts/check-inert-flag-seams.mjs` matched call sites by NAME, so two
same-named functions in
different modules were conflated. I had documented that as a known
false-positive source and moved
on — reports mentioning `sortTasksForDisplayColumn` are noise, read past
them.

That annotation was the damage. Core's `sortTasksForDisplayColumn`
genuinely never receives its
`columnFlags` argument outside its own tests. The dashboard's separate
function of the same name
(`app/components/taskSorting.ts`), called with up to five arguments from
`Lane`/`Board`/`ListView`,
was raising the arg-count max and clearing core's seam. The offender was
behind a row everyone had
been told to skip.

The gate now records the module each callee is imported from and matches
it against the seam's
declaring module.

**Measured, by reverting the change:** the scan prints `17 seams, all
supplied` and emits **no row**
for the function. With the change, it is reported. Both directions
watched.

Reported on #2783 rather than fixed from outside — core owns it, and
"wire the flags" vs "drop the
parameter and let the literal stay counted" is their judgment call.
TEMPORARY allow-list entry
carries it meanwhile; the existing staleness check fails the moment the
site becomes supplied, so
the entry cannot outlive the fix.

Two known limits remain, both inherent to name matching and both
documented in the script: the
one-supplier floor, and the `__tests__` exclusion (hence the two
permanent `ALLOWED` entries).


## And the one-supplier floor, closed the same way

I wrote in the section above that the floor "hasn't cost anything yet."
That is verbatim the
reasoning that kept the imported-shadow bug alive, so I closed it
instead of leaving the note.

`best < arity` asked only whether SOME caller supplied the argument. One
correct call site cleared
the seam while every sibling took the legacy fallback — the
`isTaskStuck` defect class, where two of
three sites omitted the flags and the gate stayed green because the
third was right. Review caught
that one. A partially-supplied seam is the harder of the two:
wholly-unsupplied is uniformly wrong,
this works on the board you tested and degrades on the column you did
not.

**Measured:** dropping the flags argument at `Column.tsx`'s supplied
call site produces
`supplied by 5/6 call sites; omitted at
packages/dashboard/app/components/Column.tsx:1 (of 2)`;
restoring returns `all supplied at every call site`. Red and green both
watched.

Two real omissions found, both on `isNearDuplicateCanonicalInactive`:

- **`TaskDetailModal.tsx`** — deliberate, and it **corrects a note I
left at that site**. The old
note said hoisting the flags state was "the actual fix." It is not, for
this call: the flags in
scope describe the *modal's* task, and the canonical is a **different
task** on a column this
component never resolves. Passing them would type-check, read as a
conversion, and answer about
the wrong task — exactly what `column-role-degraded-flags.test.ts`
exists to catch. Supplying it
  correctly needs a fetch, which is a data change and out of scope.
- **`core/task-store/branch-group-ops.ts`** — genuinely wireable (the
impl is async and already
holds `store` and `canonicalId`). Reported on #2783, not edited from
outside.

Exemptions for this class are keyed by **call site**
(`<file>::<function>`), not by function name.
A name-level entry would waive every site of a partially-supplied seam,
which is backwards — its
other sites are correct and are the reason the omission is worth
reporting. Both entries carry the
same staleness check as the name-level list and cannot outlive their
fix.

Remaining known limit, now the only one: the `__tests__` exclusion,
which makes a test-only export
read as having no callers. That is what the two permanent `ALLOWED`
entries are.


## The `__tests__` exclusion, and two allow-list entries built on false
reasons

Named as the "last remaining limit" above, so it got closed too. The
scan now reads test files for
call sites — but counts them **separately**, and a test never clears a
seam. That direction is the
dangerous one: counting test callers as suppliers would have re-hidden
core's
`sortTasksForDisplayColumn`, whose only suppliers are its own tests.
Measured by lifting its
exemption: still reported.

Both permanent allow-list entries claimed the scanner couldn't see their
callers. **Both reasons
were false**, and reading tests is what proved it:

- **`evaluateMergeBlockerGuard`** — zero callers in tests either. Its
only reference in the repo is
its own declaration; never registered as a trait hook; the
`evaluateDefaultWorkflowGuards` reader
its file header credits does not exist. The `lifecycleColumns`
conversion went onto dead code, and
its note describes a crossing the guard cannot make. Reported on #2783,
including the two things I
am explicitly *not* concluding (no `"guard"` hook is registered in
production; whether that is
  residue or a dropped registration needs core's intent).
- **`isRecoverableMissingWorktreeReviewFailure`** — 5 test call sites.
It wraps
`...WithProgress`/`...NoProgress`, the live pair called from
`self-healing.ts`, both supplying
  `reviewColumns`. Entry kept, true reason recorded.

### A wrong turn, recorded because it is the failure mode this PR is
about

I first classified no-production-caller seams as *informational* when
they weren't re-exported from
a package index, reasoning that a public export might be called
externally. That silently downgraded
`sortTasksForDisplayColumn` — a confirmed real offender — from failing
to a footnote. Publication
status has nothing to do with whether there is production behaviour to
be wrong. Reverted to the
simple rule: no production caller means inert, and it fails.

It is worth stating plainly because it is the exact shape of everything
else in this PR: a change
that made the gate read *cleaner* while making it catch *less*, and it
type-checked, passed every
test, and would have reviewed fine.

### Where that leaves the check

Every blind spot named in this PR has now been closed, and **each one
produced a real defect within
minutes of closing it** — imported shadows, the one-supplier floor, the
`__tests__` exclusion. Four
verified findings went to core, one to engine. I would not read the
remaining ~240 guards' green
gates as evidence that they are clean; I would read them as untested.


## Two guards for one question, one of them worse

Having hardened the script, I checked its older twin rather than
assuming it was fine.
`resolved-flags-seams-have-suppliers.test.ts` carried its own copy of
the trailing-flags-parameter
check — written before the script existed — with **all three** holes the
script has since closed.

**Measured on one reintroduced defect** (dropping the flags argument at
`Column.tsx`'s supplied
`isNearDuplicateCanonicalInactive` call):

| | result |
|---|---|
| `scripts/check-inert-flag-seams.mjs` | `supplied by 5/6 call sites;
omitted at .../Column.tsx:1 (of 2)` |
| this test's arity half | **3 passed** |

Deleted the arity half. Redundancy between a strong and a weak check
isn't redundancy — it's a green
result available to whoever runs the weak one, and there was no signal
at the call site telling you
which you were looking at.

The **props-shape half stays**: it has no twin in the script, and I
confirmed it still fires by
reintroducing the original `PrPanel` defect (outer component stops
destructuring `taskColumnFlags`)
— it reports `PrPanel declares taskColumnFlags but never takes it`.

Dashboard app suite: **113 files / 3921 tests** (was 3922 — the deleted
case is the difference).


## The gate started catching defects as they landed

Syncing with main brought in three fresh conversions from other workers.
The hardened check flagged
all three immediately — the first time these guards have fired on
someone else's landed code rather
than on my own.

- **`TaskCard`** — `getRunningOptionalGateBadge(task)` omitted flags
while *both* `ListView` sites
supplied. Fixed, and `taskColumnFlags` added to the `useMemo` deps: no
`exhaustive-deps` rule here,
so a memo that reads flags without listing them keeps the first-paint
`undefined` answer and
  reproduces the bug through staleness instead of omission.
- **`TaskTokenStatsPanel`** — `getTotalAgentActiveMs` omitted while
`TaskCard` supplied, so the same
runtime number came from the real column on a card and from legacy ids
in the detail modal. Now
takes `columnFlags`, supplied from `detailColumnFlags` — correct here
because the panel renders the
  modal's **own** task, unlike the near-duplicate canonical above.
- **`ListView` ×2** — passed `columnFlagsById.get(task.column)`, the
cross-workflow **union**. A task
whose own workflow doesn't declare that column gets a *neighbour
workflow's* traits. The landed
comment justified it as "this list already owns `columnFlagsById`" —
exactly the reasoning
`column-role-degraded-flags.test.ts` exists to reject. It failed on
merge and is how I found this.

Also: the `getTotalAgentActiveMs` exemption I was carrying
**self-retired**. Main wired the seam, the
staleness check failed the entry, and I removed it. That mechanism has
now paid for itself once.

### Pre-existing, NOT from this PR: `App.test.tsx` is red on main

`app/components/__tests__/App.test.tsx` fails **10 of 141** identically
with my changes, with my
changes stashed, and with main's own `App.tsx` restored. Not mine, and
not in the merge gate.

**Bisected on clean `main` checkouts, so this is measured rather than
inferred:**

| commit | date | result |
|---|---|---|
| `main~400` (`41d60f0355`) | 2026-07-25 | **140 passed** (140 tests) |
| `main~275` (`74d6513fae`) | 2026-07-27 | 3 failed / 141 |
| `main~210` (`d2ce1ba8b5`) | 2026-07-29 | 10 failed / 141 |
| `main` (`6fc98fd6c7`) | 2026-07-30 | 10 failed / 141 |

So it is **not one regression** — it degraded in two stages across
2026-07-25 → 07-29, and the test
file itself changed in that window (140 → 141 tests). Three commits
touched it there:
`73b2a32e2b`, `f26cbedf4f`, `f157bf7460`. That window overlaps the
workflow-owned lifecycle
migration, which is suggestive but not something I confirmed.

The failures are render-level, not assertion-level — `Unable to find an
element with the text: + New
Task`, `Unable to find role="dialog"`, `Unable to find ... Back nav
task`. The board appears to
render nothing. That reads like a real regression or a harness mismatch
after the lifecycle
migration, not a flake, so I have deliberately **not** quarantined it —
quarantine is for flakes, and
using it here would hide the signal. Flagging for whoever owns
`App.tsx`.

My suites: `app/__tests__` **113 files / 3921 tests** green, `tsc` 0,
lint 0, census `--strict` 0,
seam gate 0.
