Two items, both found by checking a record against the code rather than reading it. Band 3 of the roadmap is now empty.


1 · ROADMAP-TRUTH — four records called concurrency gaps open that the sweep had closed

services/api/test_rmw_sweep.py reports "43 ORM sites: 43 reasoned exempt or locked, 0 named open". docs/roadmap.md still carried RMW-LOCKGAP and RMW-TOKEN as 🟡 OPEN, and docs/security/threat-model.md still carried G-10 and G-12 as open gaps under a summary line reading "Four sites remain open".

A stale OPEN is a work item. The roadmap's ranking sends the next reader at it, the threat model presents a reviewer with a live exposure, and RMW-TOKEN's entry additionally priced its fix as "a migration (add the column, backfill, route both writers through a CAS)" — work nobody ever did, because both of its sites closed with an advisory lock already in the tree and already serving the gap next door.

Half of that entry was wrong on the day it was filed. realestate.save_appraisal took pid_lock.mutating(pid) in #552 on 2026-09-13; the entry naming it as open was written on 2026-09-14. Also corrected: #556 is titled "RMW-TOKEN" and closed a different gap (the connections pair, G-12) — citing it against this entry would look right and be wrong.

record closed by correction
RMW-LOCKGAP #555 8503b0be all six routes wrapped 2026-09-14
RMW-TOKEN #552 c7fdc658 + #572 cd5d9e24 closed with a lock, not the prescribed migration
G-12 #556 e736c4d9, #557 49f4cc0f, #572 cd5d9e24 five sites, all locked
G-10 #552 c7fdc658 + #572 cd5d9e24 both JSON collections locked

The new gate

services/api/test_gap_records.py derives the sites from the sweep's own ledgers by AST and the records from both documents by indentation, and holds any record that cites the sweep and reads as open to naming at least one still-open site. It replays the four records as they shipped at 53cfa71a — frozen under services/api/tests/fixtures/gap_records/ — and must re-find all four, and nothing else, before it may report a clean tree. Fails closed on a ledger it cannot parse, a status outside the declared set, or a missing/truncated fixture.

Six things it got wrong first, each fixed and recorded beside the code:

  • CI caught what no local run could. The replay first read those records with git show 53cfa71a:…. That works on a full clone; CI's checkout is shallow, so the object is absent and the gate failed closed on every build. Failing closed was right — but a proof-of-reach that depends on the depth of somebody's clone is not a proof, it is a dependency on an environment nobody here controls. Every neighbouring gate already embeds its pre-fix subject rather than fetching it. The records are now copied; the gate runs no git at all.
  • Twelve roadmap items were outside its population entirely — the marker list knew ✅ ◧ 🟡 ⭐ and not ⛔, ❌ or a ~~struck~~ code, so it examined 78 items where it should have examined 90, and a population smaller than it looks reports a clean tree in exactly the same words as a clean tree. The repair is the loose-vs-strict parity check, not the wider list — it found ❌ on its first run, after the other two had been added by hand from the same measurement. A hand-widened list is a list somebody stopped widening.
  • The replay was reading today's ledger. A replay is a claim about a moment; feeding it a moving input makes it a claim about nothing. Statuses are frozen alongside the records, with a mutation proving they are read.
  • Ruling on every open record reported SCALE-SEAM — an item about client.ts — as a stale concurrency gap, because 894 lines into its body it mentions _restore_version. Hence the scoping clause, learned rather than designed.
  • Without / in the identifier chain, routers/proforma.share_scenario read as routers, and RMW-TOKEN came back clean from the replay.
  • Matching a prefix of a backticked span made edit-mep, a recipe category, match the route edit.

The rule is "must name an open site", not "must not name a closed one": a genuinely open record cites its closed siblings for contrast, and RMW-LOCKGAP's named all six LOCKED routes beside the six it was about.

The gate that should have caught it

services/api/test_roadmap_status.py asks the right question — does the item's own gate report the work done? — but only for items registered in its DONE_WHEN map, and nothing forces a closing pull request to add itself. A registry reports on what it contains, and its silence is indistinguishable from a clean bill.

It also had a fail-open hole, found by mutation and fixed here. Its loop reads if not marked_open(code): PASS; continue, so a marked_open that can never say yes sends every registered item down the passing branch. Measured: breaking its bullet regex with one literal left every line green, the exit status 0, and the verdict "every item with a measurement agrees with its marker" printed over nothing.


2 · PIN-OPEN-ROW — clicking a register pin on the model opens its record

A pin on the 3D model is a register record's marker. Clicking one selected the element it sits on and wrote a line to the status bar, and that was all.

The behaviour was already written down as shipped. apps/web/src/pins/pins.ts branches topic-versus-record on click and explains why — "a topic restores a saved viewpoint, a record opens its register row". Only the first half was true.

It was filed as needing a UX decision and did not need one. The entry concluded the choice between a new tab, a side panel and a route change was open, on the strength of a grep for an opener over apps/web/src/viewer/app.ts returning zero. There is no opener in that directory: main.ts has had one since the command palette shipped. A grep bounded by one directory answers a question about that directory, and the conclusion drawn was about the application.

The handler is apps/web/src/viewer/pinOpen.ts, so app.ts did not grow — its ratchet holds at 2,442. The opener reaches the viewer as a required callback on ViewerCtx rather than an import: required so a dropped wire is a compile error instead of a dead pin, injected because the viewer reaching into the portal is the coupling the MassingViewer extraction has to unpick. Two of the tests read app.ts and main.ts as source and assert the wire, because every behavioural test passes on a handler nobody calls — which is the state this item shipped in.

What review found, all real

  • A marker click also reached the viewport, whose raycast misses a DOM overlay and then clears the selection a few frames later — undoing the highlight this handler had just set, and falsifying a sentence this pull request had written. Both marker kinds now stop the event.
  • A rejected selectByGuid took the record jump with it, although the record id came from the pin and not from the scene. Selection is best effort now, and says when it failed rather than swallowing it.
  • The jump waited a fixed 500 ms instead of the portal's own init. There were three copies of that guess in main.ts; all three now share one wait. openPortalTab also latched on "we called it once" rather than on a successful init — the defect the developer tab beside it carries a comment about.
  • That last fix created the round's only new defect, found by the next pass: making init() retryable turned every partial mutation on the way to a rejection into reachable state, so a retry would have nested a second shell inside the first. Making a failure recoverable makes every partial mutation on the way to it reachable. Guarded, and held by apps/web/src/portal/portalRetry.test.ts, whose two arms both red when the guard is removed.
  • And that guard's comment grew a ratcheted file (portal.ts 1239 > 1228). The reasoning moved to the test, where the check that holds it lives; shrunk to the cap rather than raising it. My own verification had the hole CI found — the size gate had been run two commits earlier. A gate is only evidence about the state it was run against.

Verification

  • All CI checks green on d469ebf7 — API test gate, web typecheck/test/build, CodeQL (both languages), alembic runtime-parity.
  • 715/715 backend suites and 2809/2809 web tests pass locally; typecheck, lint and build clean.
  • ruff check clean on the changed Python.
  • Every new check verified by mutation in both directions: the fixture path by deleting and truncating a fixture, the frozen statuses by reopening a site, the retry guard by removing it, the pin wire by replacing the opener with a no-op.
  • All six review threads across two rounds addressed and resolved.

…ep had closed

`test_rmw_sweep.py` reports "43 ORM sites: 43 reasoned exempt or locked, 0
named open". `docs/roadmap.md` still carried RMW-LOCKGAP and RMW-TOKEN as
OPEN, and `docs/security/threat-model.md` still carried G-10 and G-12 as open
gaps under a summary line reading "Four sites remain open". All four are
corrected against the code, each naming the pull request that closed it.

A stale OPEN is a work item, not a typo: the roadmap's ranking sends the next
reader at it, the threat model shows a reviewer a live exposure, and
RMW-TOKEN's entry priced its fix as "a migration (add the column, backfill,
route both writers through a CAS)" — work nobody ever did, because both of its
sites closed with an advisory lock already in the tree and already serving the
gap next door. Half of that entry was wrong on the day it was written:
`realestate.save_appraisal` took its lock the day before, in the sweep the gap
was split out of.

`services/api/test_gap_records.py` fails the build on the class. It derives the
sites from the sweep's own ledgers by AST and the records from both documents
by indentation, and holds any record that cites the sweep and reads as open to
naming at least one still-open site. It replays both documents as shipped at
53cfa71 and must re-find all four records, and nothing else, before it reports.

Three things it got wrong first, each fixed and recorded beside the code.
Ruling on every open record reported SCALE-SEAM — an item about `client.ts` —
as a stale concurrency gap, because 894 lines into its body it mentions
`_restore_version`; hence the scoping clause. Without `/` in the identifier
chain, `routers/proforma.share_scenario` read as `routers` and RMW-TOKEN came
back clean from the replay. Matching a prefix of a backticked span made
`edit-mep` match the route `edit`.

`services/api/test_roadmap_status.py` gained the self-tests it was missing. Its
loop reads `if not marked_open(code): PASS; continue`, so a `marked_open` that
can never say yes sends every registered item down the passing branch —
measured by mutation: breaking its bullet regex with one literal left every
line green, the exit status 0, and the verdict "every item with a measurement
agrees with its marker" printed over nothing. Its one precondition guarded that
the roadmap was readable, not that the predicate could still say yes.

715/715 backend suites pass.

📝 Walkthrough

Walkthrough

The viewer opens register records from model pins through a shared function that waits for portal initialization. Portal retries reuse the existing shell and persona listener. The roadmap and threat model update concurrency-gap records, and a test gate checks those records against sweep-ledger statuses and frozen fixtures.

Changes

Viewer Pin Navigation

Layer / File(s) Summary
Portal readiness and retry handling
apps/web/src/main.ts, apps/web/src/portal/portal.ts, apps/web/src/portal/portalRetry.test.ts, apps/web/src/viewer/pinOpen.test.ts, docs/roadmap.md, CHANGELOG.md
Portal initialization returns its in-flight or cached promise and clears it on failure. The viewer and command palette use the shared record opener. Portal retries build the shell and register the persona listener once.
Pin click handling
apps/web/src/viewer/pinOpen.ts, apps/web/src/viewer/app.ts, apps/web/src/pins/pins.ts, apps/web/src/viewer/pinOpen.test.ts, apps/web/src/main.ts, docs/roadmap.md, CHANGELOG.md
Pin clicks select an associated element when present, update the status line, and open non-topic records through an injected callback. Marker clicks stop propagation. Selection failure does not prevent record navigation. Tests cover these behaviors and status formatting.

Concurrency Gap Record Checks

Layer / File(s) Summary
Ledger-backed record checks
services/api/test_gap_records.py, CLAUDE.md, CHANGELOG.md
The gate derives function statuses from sweep ledgers, checks scoped records for open entries that cite no open function, and detects headings missed by the strict parser.
Frozen replay and test registration
services/api/test_gap_records.py, services/api/tests/fixtures/gap_records/*, services/api/test_roadmap_status.py, services/api/run_tests.py
The gate checks frozen records against frozen ledger statuses and tests a reopened-site mutation. The test runner registers the gate and roadmap-status suite, which includes predicate self-tests.
Gap record updates
docs/roadmap.md, docs/security/threat-model.md, CLAUDE.md, CHANGELOG.md
The roadmap and threat model record concurrency gaps as closed and update their closure details. Project notes describe the gate, its fixtures, and parser checks.

Comment @coderabbitai help to get the list of available commands.

A pin on the 3D model is a register record's marker — an RFI, a punch item, an
observation. Clicking one selected the element it sits on and wrote a line to
the status bar, and that was all: the record the pin stood for had no way in.
It now selects, reports, and opens the record.

The behaviour was already written down as shipped. `pins.ts::load` branches
topic-versus-record on click and explains why — "a topic restores a saved
viewpoint, a record opens its register row". Only the first half was true. A
comment describing a branch's purpose is a claim about behaviour, and that one
had been false since the branch was written.

Nothing new was designed for it. The item was filed as needing a UX decision —
a new tab, a side panel or a route change — on the strength of a grep for an
opener over `apps/web/src/viewer/app.ts` returning zero. There is no opener in
that DIRECTORY. `main.ts` has had one since the command palette shipped and
jumps to a record through it whenever a search hit is chosen. A grep bounded by
one directory answers a question about that directory, and the conclusion drawn
was about the application. That jump is now the shared `jumpToRecord`, used by
the palette and the pin alike, because two openers are two answers and the next
edit drifts one of them.

Selection stays in the viewer rather than following the user across, so coming
back to the Model workspace finds the element still highlighted.

The handler lives in `apps/web/src/viewer/pinOpen.ts`, so the viewer's `app.ts`
did not grow — the size ratchet holds at 2,442. The opener reaches the viewer
as a REQUIRED callback on `ViewerCtx` rather than an import: required so a
dropped wire is a compile error instead of a dead pin, injected because the
viewer reaching into the portal is the coupling the MassingViewer extraction
has to unpick.

Two of the eight tests read `app.ts` and `main.ts` as source and assert the
wire, because every behavioural test passes on a handler nobody calls — which
is the state this item shipped in. Verified by mutation: replacing
`openRecord: jumpToRecord` with `openRecord: () => {}` compiles, restores the
old dead pin, and reds the suite.

Band 3 is now empty. The line recording that it held one item was written
earlier the same day and was already wrong before this branch was pushed: a
count and the change that moves it must land in the same edit, not the same
session.

2804/2804 web tests pass; typecheck, lint and build clean.

@ibuilder ibuilder changed the title ROADMAP-TRUTH: four records called concurrency gaps open that the sweep had closed ROADMAP-TRUTH + PIN-OPEN-ROW: four stale gap records, the gate that missed them, and a pin that now opens its record Sep 24, 2026
…f git

CI red on aa4f8e4: `fatal: invalid object name '53cfa71a'`. The replay that
proves this analyser finds anything read the pre-fix documents with `git show`.
That works on a full clone; CI's checkout is shallow, the object is not in it,
and the gate failed closed on every build — as it is designed to, since an
analyser that cannot read its inputs must not report a clean tree.

Failing closed was right. Depending on history was not. **A proof-of-reach that
depends on the depth of somebody's clone is not a proof, it is a dependency on
an environment nobody here controls** — and it would break the same way in any
contributor's shallow clone, not only in CI. Every neighbouring gate in this
tree already embeds its pre-fix subject rather than fetching it:
`test_seeding_sweep` runs against the shipped pre-fix SAML door,
`test_system_columns` reinstates the pre-fix `_system_field`. Reaching into
history was the novel choice and the worse one.

The four records are now frozen verbatim under
`services/api/tests/fixtures/gap_records/`, copied out of 53cfa71 while that
commit was still reachable. The gate no longer runs git at all. A fixture that
is missing, or too small to hold what it must, reds the build rather than
letting the replay pass by having nothing to find — verified by deleting one
and by truncating one.

Local verification could not have caught this: the commit is present here. The
lesson is recorded in CLAUDE.md beside the gate it belongs to.

…and seventh

**A pin marker's click also reached the viewport.** `app.ts` raycasts container
clicks and calls `selectMap(null)` on a miss — asynchronously, after a race with
a 1.5s timeout. A pin is a DOM overlay, not scene geometry, so a click on one
easily raycasts to nothing: this handler selected the element and the container
handler cleared it a few frames later. That falsified the sentence this pull
request had just written, that selection stays put. *Two handlers that both
answer a click are not two features, they are a race*, and the loser was the one
the user aimed at. Both marker kinds now stop the event.

**A rejected `selectByGuid` took the record jump with it.** The record id comes
from the pin, not from the scene, so a stalled Fragments worker has no business
losing it — and the caller is a DOM `onclick` that does not hold the promise, so
it was an unhandled rejection too. Selection is best effort now, and the status
line says when it failed: an empty catch would leave a user looking at an
unhighlighted model with no account of why.

**The jump waited a fixed 500 ms instead of the portal's own init**, so a first
visit whose `api.modules()` took longer dropped it silently. There were THREE
copies of that guess in `main.ts`; the wait is consolidated rather than patched
at the site under review, because fixing the trafficked instance is not closing
the class. `openPortalTab` also latched on "we called it once" rather than on a
successful init — the defect the developer tab beside it carries a comment
about — and now returns its promise so a caller can wait for the real event.

**The gap-records replay was reading today's ledger.** A replay is a claim about
a moment; feeding it a moving input makes it a claim about nothing. The statuses
are frozen alongside the records, with a mutation proving they are read: reopen
one of RMW-LOCKGAP's own sites in the frozen ledger and that record must stop
being reported.

**Asked what happens when a heading leaves the parsed set, the answer was that
twelve already had.** The marker list knew `✅ ◧ 🟡 ⭐` and not `⛔`, `❌` or a
struck-through code, so the population was 78 roadmap items where it should have
been 90 — reported as a clean tree in exactly the same words as a clean tree.
The repair is not the wider list but the LOOSE-versus-STRICT parity check beside
it, which reds the build on a marker the gate does not know. It found `❌` on its
first run, after the other two had been added by hand from the same measurement:
*a hand-widened list is a list somebody stopped widening.*

715/715 backend suites, 2807/2807 web tests, lint and build clean.

Review round 2 on #577, one finding, and it is this pull request's own.

Making `openPortalTab` retry was the right fix: the pin jump needs to WAIT for
the portal, and a latch set before the await left the tab broken for the
session. But `PortalUI.init()` reassigns `this.root` to the content pane and
registers an `aec:persona` listener BEFORE it awaits `renderHome()`, which can
reject. Until the retry existed, a rejection was terminal and `init()` was never
re-entered, so those partial mutations were unreachable. Now they are: a retry
would nest a second shell inside the first one's content pane — every later
render writing into the wrong one — and add a duplicate persona listener that
rebuilds the rail twice, compounding with every failed init.

**Making a failure recoverable makes every partial mutation on the way to it
reachable.** The retry was the fix, and the fix is what exposed this.

The shell build and the listener are now guarded on `this.nav`, which is already
the "shell exists" sentinel `buildNav` reads. Everything after it — the module
fetch, the spine, the nav rebuild, the render — still re-runs, because a retry
that cannot render is not a retry. `reg.hookOnline()` needs no guard:
`UploadQueue` latches its own `hooked`.

`apps/web/src/portal/portalRetry.test.ts` drives the real class: force the first
`renderHome` to reject, init again, and assert one shell, one content pane and
one listener. Both arms red when the guard is removed — measured, not reasoned.

The lane ratchet caught the new file belonging to no lane, so it is claimed by
Lane A beside the `portal.ts` it tests, rather than raising the ceiling.

2809/2809 web tests, typecheck, lint and build clean.

… test

CI red on ec4dd8e: `apps/web/src/portal/portal.ts=1239 > 1228`. The retry
guard was three lines of code and eleven of comment, and `portal.ts` sits under
an extraction ratchet.

The ratchet is right and the comment was in the wrong place. The reasoning
belongs next to the check that holds it — `portalRetry.test.ts`, which already
carried most of it — and `portal.ts` keeps one line pointing there. Shrunk to
the cap rather than raising it, as the ratchet's own message asks.

**My own verification had the hole CI found**: `test_file_sizes` was run at the
gap-records stage and not again after the portal edit, so the local pass
described a tree two commits old. A gate is only evidence about the state it
was run against.

2809/2809 web tests, typecheck, lint clean; `test_file_sizes` back to
1228/1228.
