What & why

The gap. RecordComment had no outward link of any kind. An agency's comment on an
entitlement or permit was a text blob at the end of a thread: readable, and impossible to assign,
track or close. ④ made comments survive a revision — that is the inbound half of "round-tripping";
this is the outbound half R22-ENTITLEMENT still listed as remaining.

POST /projects/{pid}/modules/{key}/{rid}/comments/{cid}/promote mints a Topic carrying the comment
text, the source record's ref and its element_guids, and writes a back-link on the comment.

The back-link is the idempotency

A second promote 409s instead of minting a duplicate RFI — the failure mode a promote button
produces on every double-click. Both load-bearing assertions in
services/api/test_comment_promote.py were mutation-checked:

  • removing the 409 guard → one comment mints two RFIs, and the failure output shows both
    comment.promote activity entries side by side;
  • removing the back-link write → topic_id disappears from the comment.

Follows promote_markup (POST …/drawings/markup/{mid}/promote) rather than inventing a second
idiom: mint, carry provenance, link back, 409, audit.

Reachable, not merely built

The control renders beside the comment and is replaced by "→ RFI raised" once promoted, because a
button whose only remaining outcome is a 409 is worse than no button.

Adding it turned register.ts's extraction ratchet red, and the remedy is the one that file
states: extraction, never headroom.
The comment thread, composer and new control came out to
apps/web/src/portal/register/recordComments.ts (2,516 → 2,505, pin lowered with it). A genuine
leaf — it touches the record's comments, the API and a reload callback and nothing else on the class
— and the directory already holds three leaves extracted the same way (elementTies.ts,
schemaStale.ts, tiedElements.ts).

What the premise-check found

The ring entry demands a premise-check before anyone touches it, because it has produced a
naming-based false blocker four times. Its "Remaining:" line named two things and contradicted
itself on one
— it listed submittal packages flatly while the note directly above said the inbound
half had already shipped.

Measured against the whole surface rather than the name-matching file:

  • comment→RFI round-tripping — genuinely missing, and worse than stated: no outward link at all.
  • submittal packages — still open, for a reason nobody had written down. The inbound view is
    real (…/related returns incoming), but assembling a package to send is not, because
    services/api/modules/transmittal/module.json types items as a textarea and to_company
    as plain text
    . Package contents are prose no machine can resolve back to the records named, and
    the recipient cannot be the agency an entitlement names, since that is free text too. That is a
    schema question — reference fields — not a workflow one, which is why reading the workflow surface
    kept reporting it done.
    The roadmap now says that instead of the flat line.

Also corrected

The roadmap's argument against picking SCALE-SEAM quoted apps/web/src/api/client.ts at 2,837
lines
. It is 642 — the number was copied forward through every slice since, which is the exact
drift the rows beside it document twice.

Schema

Adds record_comments.topic_id (nullable, no server default — an existing comment has not been
promoted, and NULL says that without inventing a state). Migration
c8a4e2f71b39, down_revision f4b8c2d51e93; test_alembic_single_head.py reports one head across
28 migrations.

…trix loses

Moves `lodSummary`/`setLod` and `phasing`/`setPhase` out of `client.ts` into
`api/model.ts`. They answer one question — *what state are the model's elements
in, and set it?* — and `client.ts` goes 727 -> 711, 76 methods above the STAYING
banner.

The grouping is derived, not asserted:

- identical return shape `{ total, <x>ed, prop, counts: Record<...> }`;
- both writers are `(pid, guids, <enum>, publish) -> editIfc`;
- both readers are consumed by `viewer/tools/modelStatePanels.ts` (251, 316);
- both writers sit unwired and *adjacent* on `clientCallers.test.ts`'s UNCALLED
  allowlist;
- `model.ts` already owned `/model/lod/census`, `/lod/handover-readiness` and
  `/lod/assessment`, while the base distribution `/projects/{pid}/lod` was left
  behind in `client.ts` — `lodSummary` was a sibling separated from its family.

`authoring_matrix.py` DISAGREES and is recorded as the losing vote rather than
elided. It files `set_lod` under `data` and `set_phase` under `lifecycle`,
because it categorises by the IFC output each recipe writes — an LOD stage tag
against `Massing_Phasing.Status`. Different property sets, same question, which
is (89)'s "storage is a HOW" trap. This is the first slice where the matrix has
been wrong after being right three running.

It also MEETS (94)'s objection rather than overriding it: that slice declined
`setPhase` because taking the writer alone would have stranded `phasing()`, the
reader/writer split (87) had to undo. Both halves move together here.

The four names are added to `surface.test.ts` because its floor is a slack
ratchet (788 actual vs 751 floor) — the count alone would not notice a loss —
and because the UNCALLED allowlist is about call sites, not the surface.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
`test_file_sizes.py` / `test_claude_md_gates.py` / `test_roadmap_status.py` /

…ness that actually bounds

Moves `lod500`, `setManufacturerInfo` and `attachOmDocument` out of `client.ts`
into `api/model.ts`, rejoining `verifyAsbuilt` and `recordAsbuiltDimension`
which (94) moved. `client.ts` goes 711 -> 698, 73 methods above the STAYING
banner.

TWO BOUNDING WITNESSES, derived independently, agreeing:

- `openAsBuiltPanel` in `viewer/tools/modelStatePanels.ts` calls exactly five
  API methods — read off that function's brace closure rather than grepped for,
  so it is the closure of a scope and not a sample. Two of the five were
  already in `model.ts`.
- The reader's own response type names its writer set field by field:
  `verified`/`by_method` from `verify_asbuilt`;
  `with_dimensions`/`dimensions_out_of_tolerance` from
  `record_asbuilt_dimension`; `with_manufacturer`/`with_serial` from
  `set_manufacturer_info`; `with_om_docs`/`om_documents` from
  `attach_om_document`. The backend route says it in prose: "Stamp elements
  with the `verify_asbuilt` recipe."

A reader whose response type enumerates its writers is a DERIVED population.
After eight slices of sampling, that is the first grouping witness here that
bounds a set instead of illustrating one.

WHAT CORROBORATES IS NOT WHAT BOUNDS. `test_lod500.py` reaches exactly three
recipes — `attach_om_document`, `set_manufacturer_info`, `verify_asbuilt` — and
OMITS `record_asbuilt_dimension`, which is unambiguously in this family. It
agrees with the answer without being able to establish it. Three slices claimed
"and no others" off a test file and were wrong all three times.

NOT CLAIMED, and said in the header, the pin, the changelog and the roadmap
rather than only in review: `attachDocument` stays in `client.ts`, takes a
`purpose` parameter, and `asbuilt_summary` counts ANY purpose-tagged document
reference — so "every writer of `with_om_docs` moves here" is false. The field
map is of the recipes each field was designed around, not of everything that
can set it.

Two sources disagree and lose for the same reason: `attach_om_document` is a
purpose-tagged wrapper of `detailing.attach_document`, and
`authoring_matrix.py` files it and `set_manufacturer_info` under `data`. The
first is a shared HELPER, the second a STORAGE bucket — the groupings (89) and
(90) each had to reject. The matrix is the losing vote twice running after
being right three times.

Also fixes the extraction helper: it terminated its brace count on the method
signature line, so a signature wrapping across two lines with no opening brace
on the first read as a 3-line method. `attachOmDocument` is 6.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py`, `test_ruff_scope.py`,
`test_reachable.py` all 0.

… and was not

Moves `editHistory`, `editUndo` and `editRedo` out of `client.ts` into
`api/authoring.ts`. `client.ts` goes 698 -> 687, 70 methods above the STAYING
banner.

WHY THAT MIXIN: `editIfc`, already there, is the PUSH they pop. `authoring.py`
records the pre-edit version on every `/edit` call "so this edit can be undone",
`_restore_version` pops that stack, and `edit_history.state()` reads its depths.
One stack, and the operation that fills it was already in this file.

The types agree: both writers return `{restored, state: {can_undo, can_redo}}`,
and `state` is `editHistory`'s own return type minus the depths — the writers
hand back the reader's answer. That is a type-level relation, not the shared
`/edit/` prefix. The prefix is real and is deliberately not the argument, since
a route prefix is exactly what the verification slice was caught grouping on.

A HYPOTHESIS TESTED AND WITHDRAWN, which is the part worth keeping. "Undo
restores the prior model version" makes `model.ts` the obvious home — it owns
`modelVersions`, `versionDiff`, `versionCostDelta`. It is the wrong home: those
read `/projects/{pid}/versions` out of `bim.py`, while undo pops a DIFFERENT
stack, the `edit_history` sidecar, which `recipe_log.py` describes as a list of
file paths with "No recipe, no parameters, no actor". Two stacks, one word — and
the word is what made the wrong answer look obvious. Second withdrawal of a
plausible destination after checking it, after (93) withdrew (92)'s `HttpCore`
forecast.

THE BOUND IS WEAKER THAN (96)'s AND IS STATED THAT WAY. `app.ts`'s S4 block
wires `refreshUndo` (calling only `editHistory`) and `doUndoRedo` (calling only
`editUndo`/`editRedo`), so the union is exactly these three — but that unit is a
block delimited by reading, not a closure the braces define. It corroborates; it
does not bound. Not every set has a witness as strong as the last one's, and
promoting a block to a closure would be this sequence's own recurring defect.

…flagged one

CodeRabbit flagged `editUndo`'s docstring on #414: it says "restore the prior
model version + republish" unconditionally, but `publish` defaults to true and
can be false. Verified against the backend — `_restore_version` guards the
republish with `if publish:` — so the claim is wrong whenever a caller passes
`publish: false`.

Grepping every site of that wording found the same unconditional claim in THREE
live places, not one:

- `apps/web/src/api/authoring.ts` — `editUndo` (the flagged one)
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/undo` route
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/redo` route

All three now say republishing happens only when `publish`. The remaining hits
are UI button labels, where the call site never passes the flag so republish
really is unconditional, and historical CHANGELOG entries; both are correct as
written and are left alone.

Also fixes the same defect's other half in the same five lines: the declared
return type omitted `publish`, which the backend adds as `"running"` when it
republishes. Correcting the prose while leaving the type silent about the same
conditional would be the half-applied fix this sequence has twice been caught
making.

…module but not the codebase

Moves `elementDetailing`, `classify`, `applyDetailingRules`, `validateDetailing`
and `attachDocument` out of `client.ts` into a new `api/detailing.ts`.
`client.ts` goes 687 -> 665, 65 methods above the STAYING banner.

WHAT THEY ANSWER: what informational carriers are attached to this element,
write them, and which are missing?

THE WITNESS IS A 1:1 AND TOTAL FIELD-TO-WRITER MAP, the shape (96) established.
`element_detailing` walks `HasAssociations` and branches on exactly two
relationship types, and `detailing.py` holds exactly two writers, one per
response array:

  classifications[]  <-  classify        (IfcRelAssociatesClassification)
  documents[]        <-  attachDocument  (IfcRelAssociatesDocument)

The map is read out of the reader's own body, not matched on names. The other
two methods are those same writes automated and audited: `applyDetailingRules`
runs the condition-to-content rule set and writes both carrier kinds,
`validateDetailing` reports elements a rule applies to that lack the code.

TOTAL OVER THE MODULE, NOT THE CODEBASE, and the difference is the claim.
`attachOmDocument` — moved to `model.ts` in (96) — wraps the SAME
`detailing.attach_document` and also lands in `documents[]`, so "these are all
the writers of this reader's fields" is false. That overlap was recorded when it
moved, which is why it was on hand to qualify this slice rather than being found
in review.

ADJACENCY AGREED WITH THE ANSWER AND IS NOT EVIDENCE FOR IT. These five were
contiguous in `client.ts`; unlike (95), where non-contiguity was the whole
argument, a positional split would have found this set too. Stated precisely
because it looks like support.

ALSO RECORDED: `api.classify()` has no call site — `detailingSection.ts` drives
the recipe through the generic `authorAndReload` path, bypassing the typed
method, and `clientCallers.test.ts` counts it reached because it matches bare
string literals as well as calls. That looseness is deliberate per that file's
own docstring, so it is a limit of the gate rather than a defect in it.

The new mixin needs `editIfc`, so it declares `NeedsEditIfc` and composes
outside `withAuthoring`; `compositionOrder.test.ts` gains a fourth assertion.
MUTATION-CHECKED: relaxing the constraint to `Ctor<any>` produces "TS2578:
Unused '@ts-expect-error' directive" on exactly the new line, so it fails for
the reason claimed rather than merely passing.

The extraction removed 27 lines and the banner plus import added 5 back — caught
by the ratchet, not by me, the same way (94) found its own banner growth.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py` all 0.

…s wrong until now

Moves `contentCatalog`, `placeContent` and `importContent` out of `client.ts`
into `api/authoring.ts`. `client.ts` goes 665 -> 648, 62 methods above the
STAYING banner.

WHAT THEY ANSWER: what pre-made content can I place, and place it?

THE WITNESS IS A ROLE-FOR-ROLE PARALLEL with the family shelf already in that
file, read off the signatures rather than the shared noun:

  catalog reader    familyCatalog()  {count, categories: Record<..>}
                    contentCatalog() {count, note, groups: Record<..>}
  placer            placeFamily(pid, family, position)
                    placeContent(pid, category, point, name)
  multipart import  async importFamilies(pid, file, ..)
                    async importContent(pid, file, opts)

Three roles, three methods each, matching shapes and arities. A parallel between
two method TRIPLES is structural; "both are shelves" would have been a shared
word, which is the grouping (88) and (89) each had to reject.

THE DESTINATION'S OWN FIRST LINE WAS WRONG UNTIL THIS COMMIT. `authoring.ts` has
described itself as holding "the family/content shelf" while containing ZERO
content methods — the word's only other appearances there are an HTTP header and
a sentence about IFC *type* content. The docstring stated an intended scope as
fact.

That is recorded as corroboration that was FALSE, not as evidence. A header
agreeing with the answer is worth nothing until someone checks whether it is
true, and this one had been wrong for as long as it had existed. It is the
smallest possible instance of the drift the project instructions keep warning
about.

…ed at its real strength

Moves `elementConnections` and `connectElements` out of `client.ts` into
`api/model.ts`. `client.ts` goes 648 -> 642, 60 methods above the STAYING
banner.

WHAT THEY ANSWER: what is physically joined to what, and record a joint?

THE PAIR IS BOUND BY THE BACKEND NAMING ITS OWN WRITER, the (96) shape: the
`/element-connections` route docstring reads "Author edges with the
`connect_elements` recipe (POST /edit with {guid_a, guid_b})". Reader and
writer, one relationship type (IfcRelConnectsElements), both marked B5.

THE DESTINATION ARGUMENT IS WEAKER THAN THE PAIRING ARGUMENT AND IS LABELLED SO.
`model.ts` owns `modelGraphStats`, whose `by_rel` counts the IFC relationship
graph BY RELATION — IfcRelConnectsElements being one — and `graphNeighbors`,
which walks it. So this pair is one relation of a graph the file already reads,
plus its authoring verb. That is a SPECIALISATION, not an identity: the graph
methods are generic traversal over every IfcRel*, these two are one relation
with a verb attached. The pairing is evidenced; the placement is a judgement,
and collapsing the two into one confident sentence is the overstatement this
sequence keeps catching.

TWO CANDIDATES REJECTED ON CHECKABLE GROUNDS. `connections.ts` is the trap: it
is DATA-SOURCE connections — SQL, ACC, Procore — sharing nothing with this but
the English word, and it is the file a name-based search lands on first. (97)
found two version stacks behind one word; this is the same collision in a
destination rather than a source. `elements.ts` holds element ATTRIBUTES and
views, and a relationship between two elements is not an attribute of either.

`addBasePlate`/`addShearTab` did not come despite sharing `connections.py` with
these: a backend module is a HOW, the grouping (89) had to reject, and those two
author PHYSICAL assemblies rather than relationship edges.

FOUND WHILE DERIVING, RECORDED NOT FIXED: `add_connection_assembly` (B5,
IfcRelConnectsWithRealizingElements) has no client method anywhere in
`apps/web/src` — a backend recipe with no web exposure, the class (93) recorded
for three MEP recipes.

…owns

`RecordComment` had NO outward link of any kind. An agency's comment on an
`entitlement` or `permit` was a text blob at the end of a thread: readable, and
impossible to assign, track or close. ④ made comments survive a revision — the
INBOUND half of "round-tripping"; this is the outbound half the ring entry still
listed as remaining.

`POST /projects/{pid}/modules/{key}/{rid}/comments/{cid}/promote` mints a Topic
carrying the comment text, the source record's ref and its `element_guids`, and
writes a back-link on the comment.

THE BACK-LINK IS THE IDEMPOTENCY. A second promote 409s instead of minting a
duplicate RFI — the failure mode a promote button produces on every
double-click. Both load-bearing assertions in `test_comment_promote.py` were
MUTATION-CHECKED: removing the 409 guard makes one comment mint two RFIs (the
failure output shows both `comment.promote` activity entries), and removing the
back-link write drops `topic_id` from the comment.

Follows `promote_markup` rather than inventing a second idiom — mint, carry
provenance, link back, 409, audit.

REACHABLE, NOT MERELY BUILT: the control renders beside the comment and is
replaced by "→ RFI raised" once promoted, because a button whose only remaining
outcome is a 409 is worse than no button.

Adding it turned `register.ts`'s extraction ratchet red, and the remedy is the
one that file states — extraction, never headroom. The comment thread, composer
and new control came out to `portal/register/recordComments.ts` (2,516 -> 2,505,
pin lowered with it). A genuine leaf: it touches the record's comments, the API
and a reload callback and nothing else on the class, and the directory already
holds three leaves extracted the same way.

WHAT THE PREMISE-CHECK FOUND, and it is why this slice exists. The entry's
"Remaining:" line named two things and contradicted itself on one — it listed
submittal packages flatly while the note above it said the inbound half had
shipped. Measured: the inbound view is real, but assembling a package to send is
not, because `modules/transmittal/module.json` types `items` as a textarea and
`to_company` as plain text. Package contents are prose no machine can resolve
back to the records named, and the recipient cannot be the agency an
`entitlement` names, since that is free text too. That is a SCHEMA question, not
a workflow one — which is why reading the workflow surface kept reporting it
done. The roadmap now says that instead of the flat line.

Also corrected: the roadmap's argument against picking SCALE-SEAM quoted
`client.ts` at 2,837 lines. It is 642 — copied forward through every slice since,
the exact drift the rows beside it document twice.

Verified: tsc 0, lint 0, build 0, `vitest run src/portal src/api` 50 files / 275
tests, ruff (the CI command, from `services/api`) 0, and `test_comment_promote`,
`test_modules`, `test_topic_lifecycle`, `test_reachable`, `test_declared_imports`,
`test_ruff_scope`, `test_file_sizes`, `test_claude_md_gates`,
`test_roadmap_status`, `test_doc_substance`, `test_alembic_single_head` all 0.
Full 660-suite running as a cross-check.

This commit was built on origin/main, which already carries (95)-(100) as
squashes; the remote branch carries their pre-squash originals plus an earlier
reconciliation. Verified before merging: the content diff between the remote
branch and origin/main is empty, so the branch holds no unmerged work.

-s ours keeps this branch's tree (origin/main plus R22-ENTITLEMENT ⑤) and lets
the push fast-forward without rewriting the remote branch's commits.

📝 Walkthrough

Walkthrough

The change adds an API that promotes module-record comments into RFI or issue topics. It stores a back-link, rejects duplicate promotion, exposes the state through the register UI, and documents the shipped behavior.

Changes

Comment Promotion

Layer / File(s) Summary
Backend promotion flow
services/api/..., services/api/migrations/...
The API stores topic_id, creates RFI or issue topics with source data, audits the action, and returns 409 for duplicate promotion.
Register comment controls
apps/web/src/api/..., apps/web/src/portal/register/...
The web client promotes comments, displays the promotion state, and extracts the comment thread and composer into recordComments.ts.
Promotion validation coverage
services/api/test_comment_promote.py, services/api/run_tests.py
Tests cover successful promotion, provenance, element links, duplicate requests, invalid kinds, record scoping, whitespace-only comments, and concurrent requests.
Project records and changelog
CHANGELOG.md, docs/roadmap.md, services/api/test_file_sizes.py
Project records describe the shipped feature and correct roadmap and file-size entries.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 5c79d

Concurrent requests can create duplicate RFIs, while whitespace-only comments can cause promotion to return 500. These issues should be fixed before merge.

Comment thread services/api/src/aec_api/modules.py
Comment thread services/api/src/aec_api/modules.py Outdated
…d a blank one no longer 500s

Two findings on #434, both reproduced before fixing and both mutation-checked after.

**A whitespace-only comment 500s on promote.** The comment route takes
`text: str = Body(...)` with no min-length, so `{"text": "   \n  "}` is a 201.
Promoting it ran `.strip().splitlines()[0]` over an empty list — IndexError.
The `or f"{key} {ref} review comment"` fallback written for exactly this case
had never been reachable at all: when the list is non-empty its first element
is never blank, so the `or` arm could not fire. The guard makes it live.

**Promotion idempotency was not atomic — and the damage is worse than a
duplicate.** `SessionLocal` is `expire_on_commit=False`, so a request that read
the comment before a concurrent promote committed keeps seeing a null back-link
for as long as it holds the session; the `if cm.topic_id` guard reads that stale
copy. A plain assignment then let the later writer overwrite the back-link,
minting a second RFI AND orphaning the first, whose Topic no comment pointed at
any more. The claim is now a conditional `UPDATE ... WHERE topic_id IS NULL`:
under Postgres read-committed the loser blocks on the winner's row lock and
re-evaluates the predicate against the committed row; under SQLite the writes
serialize to the same effect. Rolling back discards the Topic flushed a moment
earlier, so a losing promote leaves nothing behind.

The race test is deterministic rather than timing-dependent — the loser reads,
the winner commits, the loser proceeds from its stale identity map, which is the
production sequence. Mutation-checked both ways: restoring the unguarded index
raises IndexError, restoring the plain assignment fails "a stale-read promote
must be refused, not duplicated".

* SCALE-SEAM (95) — element state: two read/write pairs, and why the matrix loses

Moves `lodSummary`/`setLod` and `phasing`/`setPhase` out of `client.ts` into
`api/model.ts`. They answer one question — *what state are the model's elements
in, and set it?* — and `client.ts` goes 727 -> 711, 76 methods above the STAYING
banner.

The grouping is derived, not asserted:

- identical return shape `{ total, <x>ed, prop, counts: Record<...> }`;
- both writers are `(pid, guids, <enum>, publish) -> editIfc`;
- both readers are consumed by `viewer/tools/modelStatePanels.ts` (251, 316);
- both writers sit unwired and *adjacent* on `clientCallers.test.ts`'s UNCALLED
  allowlist;
- `model.ts` already owned `/model/lod/census`, `/lod/handover-readiness` and
  `/lod/assessment`, while the base distribution `/projects/{pid}/lod` was left
  behind in `client.ts` — `lodSummary` was a sibling separated from its family.

`authoring_matrix.py` DISAGREES and is recorded as the losing vote rather than
elided. It files `set_lod` under `data` and `set_phase` under `lifecycle`,
because it categorises by the IFC output each recipe writes — an LOD stage tag
against `Massing_Phasing.Status`. Different property sets, same question, which
is (89)'s "storage is a HOW" trap. This is the first slice where the matrix has
been wrong after being right three running.

It also MEETS (94)'s objection rather than overriding it: that slice declined
`setPhase` because taking the writer alone would have stranded `phasing()`, the
reader/writer split (87) had to undo. Both halves move together here.

The four names are added to `surface.test.ts` because its floor is a slack
ratchet (788 actual vs 751 floor) — the count alone would not notice a loss —
and because the UNCALLED allowlist is about call sites, not the surface.

* SCALE-SEAM (96) — the as-built question's aggregate reader, and a witness that actually bounds

Moves `lod500`, `setManufacturerInfo` and `attachOmDocument` out of `client.ts`
into `api/model.ts`, rejoining `verifyAsbuilt` and `recordAsbuiltDimension`
which (94) moved. `client.ts` goes 711 -> 698, 73 methods above the STAYING
banner.

TWO BOUNDING WITNESSES, derived independently, agreeing:

- `openAsBuiltPanel` in `viewer/tools/modelStatePanels.ts` calls exactly five
  API methods — read off that function's brace closure rather than grepped for,
  so it is the closure of a scope and not a sample. Two of the five were
  already in `model.ts`.
- The reader's own response type names its writer set field by field:
  `verified`/`by_method` from `verify_asbuilt`;
  `with_dimensions`/`dimensions_out_of_tolerance` from
  `record_asbuilt_dimension`; `with_manufacturer`/`with_serial` from
  `set_manufacturer_info`; `with_om_docs`/`om_documents` from
  `attach_om_document`. The backend route says it in prose: "Stamp elements
  with the `verify_asbuilt` recipe."

A reader whose response type enumerates its writers is a DERIVED population.
After eight slices of sampling, that is the first grouping witness here that
bounds a set instead of illustrating one.

WHAT CORROBORATES IS NOT WHAT BOUNDS. `test_lod500.py` reaches exactly three
recipes — `attach_om_document`, `set_manufacturer_info`, `verify_asbuilt` — and
OMITS `record_asbuilt_dimension`, which is unambiguously in this family. It
agrees with the answer without being able to establish it. Three slices claimed
"and no others" off a test file and were wrong all three times.

NOT CLAIMED, and said in the header, the pin, the changelog and the roadmap
rather than only in review: `attachDocument` stays in `client.ts`, takes a
`purpose` parameter, and `asbuilt_summary` counts ANY purpose-tagged document
reference — so "every writer of `with_om_docs` moves here" is false. The field
map is of the recipes each field was designed around, not of everything that
can set it.

Two sources disagree and lose for the same reason: `attach_om_document` is a
purpose-tagged wrapper of `detailing.attach_document`, and
`authoring_matrix.py` files it and `set_manufacturer_info` under `data`. The
first is a shared HELPER, the second a STORAGE bucket — the groupings (89) and
(90) each had to reject. The matrix is the losing vote twice running after
being right three times.

Also fixes the extraction helper: it terminated its brace count on the method
signature line, so a signature wrapping across two lines with no opening brace
on the first read as a 3-line method. `attachOmDocument` is 6.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py`, `test_ruff_scope.py`,
`test_reachable.py` all 0.

* SCALE-SEAM (97) — the undo stack, and a destination that looked right and was not

Moves `editHistory`, `editUndo` and `editRedo` out of `client.ts` into
`api/authoring.ts`. `client.ts` goes 698 -> 687, 70 methods above the STAYING
banner.

WHY THAT MIXIN: `editIfc`, already there, is the PUSH they pop. `authoring.py`
records the pre-edit version on every `/edit` call "so this edit can be undone",
`_restore_version` pops that stack, and `edit_history.state()` reads its depths.
One stack, and the operation that fills it was already in this file.

The types agree: both writers return `{restored, state: {can_undo, can_redo}}`,
and `state` is `editHistory`'s own return type minus the depths — the writers
hand back the reader's answer. That is a type-level relation, not the shared
`/edit/` prefix. The prefix is real and is deliberately not the argument, since
a route prefix is exactly what the verification slice was caught grouping on.

A HYPOTHESIS TESTED AND WITHDRAWN, which is the part worth keeping. "Undo
restores the prior model version" makes `model.ts` the obvious home — it owns
`modelVersions`, `versionDiff`, `versionCostDelta`. It is the wrong home: those
read `/projects/{pid}/versions` out of `bim.py`, while undo pops a DIFFERENT
stack, the `edit_history` sidecar, which `recipe_log.py` describes as a list of
file paths with "No recipe, no parameters, no actor". Two stacks, one word — and
the word is what made the wrong answer look obvious. Second withdrawal of a
plausible destination after checking it, after (93) withdrew (92)'s `HttpCore`
forecast.

THE BOUND IS WEAKER THAN (96)'s AND IS STATED THAT WAY. `app.ts`'s S4 block
wires `refreshUndo` (calling only `editHistory`) and `doUndoRedo` (calling only
`editUndo`/`editRedo`), so the union is exactly these three — but that unit is a
block delimited by reading, not a closure the braces define. It corroborates; it
does not bound. Not every set has a witness as strong as the last one's, and
promoting a block to a closure would be this sequence's own recurring defect.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* Correct the undo/redo republish docs — all three sites, not just the flagged one

CodeRabbit flagged `editUndo`'s docstring on #414: it says "restore the prior
model version + republish" unconditionally, but `publish` defaults to true and
can be false. Verified against the backend — `_restore_version` guards the
republish with `if publish:` — so the claim is wrong whenever a caller passes
`publish: false`.

Grepping every site of that wording found the same unconditional claim in THREE
live places, not one:

- `apps/web/src/api/authoring.ts` — `editUndo` (the flagged one)
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/undo` route
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/redo` route

All three now say republishing happens only when `publish`. The remaining hits
are UI button labels, where the call site never passes the flag so republish
really is unconditional, and historical CHANGELOG entries; both are correct as
written and are left alone.

Also fixes the same defect's other half in the same five lines: the declared
return type omitted `publish`, which the backend adds as `"running"` when it
republishes. Correcting the prose while leaving the type silent about the same
conditional would be the half-applied fix this sequence has twice been caught
making.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, `test_file_sizes.py` 0.

* SCALE-SEAM (98) — detailing carriers, and a field map total over one module but not the codebase

Moves `elementDetailing`, `classify`, `applyDetailingRules`, `validateDetailing`
and `attachDocument` out of `client.ts` into a new `api/detailing.ts`.
`client.ts` goes 687 -> 665, 65 methods above the STAYING banner.

WHAT THEY ANSWER: what informational carriers are attached to this element,
write them, and which are missing?

THE WITNESS IS A 1:1 AND TOTAL FIELD-TO-WRITER MAP, the shape (96) established.
`element_detailing` walks `HasAssociations` and branches on exactly two
relationship types, and `detailing.py` holds exactly two writers, one per
response array:

  classifications[]  <-  classify        (IfcRelAssociatesClassification)
  documents[]        <-  attachDocument  (IfcRelAssociatesDocument)

The map is read out of the reader's own body, not matched on names. The other
two methods are those same writes automated and audited: `applyDetailingRules`
runs the condition-to-content rule set and writes both carrier kinds,
`validateDetailing` reports elements a rule applies to that lack the code.

TOTAL OVER THE MODULE, NOT THE CODEBASE, and the difference is the claim.
`attachOmDocument` — moved to `model.ts` in (96) — wraps the SAME
`detailing.attach_document` and also lands in `documents[]`, so "these are all
the writers of this reader's fields" is false. That overlap was recorded when it
moved, which is why it was on hand to qualify this slice rather than being found
in review.

ADJACENCY AGREED WITH THE ANSWER AND IS NOT EVIDENCE FOR IT. These five were
contiguous in `client.ts`; unlike (95), where non-contiguity was the whole
argument, a positional split would have found this set too. Stated precisely
because it looks like support.

ALSO RECORDED: `api.classify()` has no call site — `detailingSection.ts` drives
the recipe through the generic `authorAndReload` path, bypassing the typed
method, and `clientCallers.test.ts` counts it reached because it matches bare
string literals as well as calls. That looseness is deliberate per that file's
own docstring, so it is a limit of the gate rather than a defect in it.

The new mixin needs `editIfc`, so it declares `NeedsEditIfc` and composes
outside `withAuthoring`; `compositionOrder.test.ts` gains a fourth assertion.
MUTATION-CHECKED: relaxing the constraint to `Ctor<any>` produces "TS2578:
Unused '@ts-expect-error' directive" on exactly the new line, so it fails for
the reason claimed rather than merely passing.

The extraction removed 27 lines and the banner plus import added 5 back — caught
by the ratchet, not by me, the same way (94) found its own banner growth.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* SCALE-SEAM (99) — the content shelf, and a destination header that was wrong until now

Moves `contentCatalog`, `placeContent` and `importContent` out of `client.ts`
into `api/authoring.ts`. `client.ts` goes 665 -> 648, 62 methods above the
STAYING banner.

WHAT THEY ANSWER: what pre-made content can I place, and place it?

THE WITNESS IS A ROLE-FOR-ROLE PARALLEL with the family shelf already in that
file, read off the signatures rather than the shared noun:

  catalog reader    familyCatalog()  {count, categories: Record<..>}
                    contentCatalog() {count, note, groups: Record<..>}
  placer            placeFamily(pid, family, position)
                    placeContent(pid, category, point, name)
  multipart import  async importFamilies(pid, file, ..)
                    async importContent(pid, file, opts)

Three roles, three methods each, matching shapes and arities. A parallel between
two method TRIPLES is structural; "both are shelves" would have been a shared
word, which is the grouping (88) and (89) each had to reject.

THE DESTINATION'S OWN FIRST LINE WAS WRONG UNTIL THIS COMMIT. `authoring.ts` has
described itself as holding "the family/content shelf" while containing ZERO
content methods — the word's only other appearances there are an HTTP header and
a sentence about IFC *type* content. The docstring stated an intended scope as
fact.

That is recorded as corroboration that was FALSE, not as evidence. A header
agreeing with the answer is worth nothing until someone checks whether it is
true, and this one had been wrong for as long as it had existed. It is the
smallest possible instance of the drift the project instructions keep warning
about.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py` all 0.

* SCALE-SEAM (100) — the element-connection pair, and a destination named at its real strength

Moves `elementConnections` and `connectElements` out of `client.ts` into
`api/model.ts`. `client.ts` goes 648 -> 642, 60 methods above the STAYING
banner.

WHAT THEY ANSWER: what is physically joined to what, and record a joint?

THE PAIR IS BOUND BY THE BACKEND NAMING ITS OWN WRITER, the (96) shape: the
`/element-connections` route docstring reads "Author edges with the
`connect_elements` recipe (POST /edit with {guid_a, guid_b})". Reader and
writer, one relationship type (IfcRelConnectsElements), both marked B5.

THE DESTINATION ARGUMENT IS WEAKER THAN THE PAIRING ARGUMENT AND IS LABELLED SO.
`model.ts` owns `modelGraphStats`, whose `by_rel` counts the IFC relationship
graph BY RELATION — IfcRelConnectsElements being one — and `graphNeighbors`,
which walks it. So this pair is one relation of a graph the file already reads,
plus its authoring verb. That is a SPECIALISATION, not an identity: the graph
methods are generic traversal over every IfcRel*, these two are one relation
with a verb attached. The pairing is evidenced; the placement is a judgement,
and collapsing the two into one confident sentence is the overstatement this
sequence keeps catching.

TWO CANDIDATES REJECTED ON CHECKABLE GROUNDS. `connections.ts` is the trap: it
is DATA-SOURCE connections — SQL, ACC, Procore — sharing nothing with this but
the English word, and it is the file a name-based search lands on first. (97)
found two version stacks behind one word; this is the same collision in a
destination rather than a source. `elements.ts` holds element ATTRIBUTES and
views, and a relationship between two elements is not an attribute of either.

`addBasePlate`/`addShearTab` did not come despite sharing `connections.py` with
these: a backend module is a HOW, the grouping (89) had to reject, and those two
author PHYSICAL assemblies rather than relationship edges.

FOUND WHILE DERIVING, RECORDED NOT FIXED: `add_connection_assembly` (B5,
IfcRelConnectsWithRealizingElements) has no client method anywhere in
`apps/web/src` — a backend recipe with no web exposure, the class (93) recorded
for three MEP recipes.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* R22-ENTITLEMENT ⑤ — an agency review comment becomes an RFI somebody owns

`RecordComment` had NO outward link of any kind. An agency's comment on an
`entitlement` or `permit` was a text blob at the end of a thread: readable, and
impossible to assign, track or close. ④ made comments survive a revision — the
INBOUND half of "round-tripping"; this is the outbound half the ring entry still
listed as remaining.

`POST /projects/{pid}/modules/{key}/{rid}/comments/{cid}/promote` mints a Topic
carrying the comment text, the source record's ref and its `element_guids`, and
writes a back-link on the comment.

THE BACK-LINK IS THE IDEMPOTENCY. A second promote 409s instead of minting a
duplicate RFI — the failure mode a promote button produces on every
double-click. Both load-bearing assertions in `test_comment_promote.py` were
MUTATION-CHECKED: removing the 409 guard makes one comment mint two RFIs (the
failure output shows both `comment.promote` activity entries), and removing the
back-link write drops `topic_id` from the comment.

Follows `promote_markup` rather than inventing a second idiom — mint, carry
provenance, link back, 409, audit.

REACHABLE, NOT MERELY BUILT: the control renders beside the comment and is
replaced by "→ RFI raised" once promoted, because a button whose only remaining
outcome is a 409 is worse than no button.

Adding it turned `register.ts`'s extraction ratchet red, and the remedy is the
one that file states — extraction, never headroom. The comment thread, composer
and new control came out to `portal/register/recordComments.ts` (2,516 -> 2,505,
pin lowered with it). A genuine leaf: it touches the record's comments, the API
and a reload callback and nothing else on the class, and the directory already
holds three leaves extracted the same way.

WHAT THE PREMISE-CHECK FOUND, and it is why this slice exists. The entry's
"Remaining:" line named two things and contradicted itself on one — it listed
submittal packages flatly while the note above it said the inbound half had
shipped. Measured: the inbound view is real, but assembling a package to send is
not, because `modules/transmittal/module.json` types `items` as a textarea and
`to_company` as plain text. Package contents are prose no machine can resolve
back to the records named, and the recipient cannot be the agency an
`entitlement` names, since that is free text too. That is a SCHEMA question, not
a workflow one — which is why reading the workflow surface kept reporting it
done. The roadmap now says that instead of the flat line.

Also corrected: the roadmap's argument against picking SCALE-SEAM quoted
`client.ts` at 2,837 lines. It is 642 — copied forward through every slice since,
the exact drift the rows beside it document twice.

Verified: tsc 0, lint 0, build 0, `vitest run src/portal src/api` 50 files / 275
tests, ruff (the CI command, from `services/api`) 0, and `test_comment_promote`,
`test_modules`, `test_topic_lifecycle`, `test_reachable`, `test_declared_imports`,
`test_ruff_scope`, `test_file_sizes`, `test_claude_md_gates`,
`test_roadmap_status`, `test_doc_substance`, `test_alembic_single_head` all 0.
Full 660-suite running as a cross-check.

* R22-ENTITLEMENT ⑤ review: promotion claims the comment atomically, and a blank one no longer 500s

Two findings on #434, both reproduced before fixing and both mutation-checked after.

**A whitespace-only comment 500s on promote.** The comment route takes
`text: str = Body(...)` with no min-length, so `{"text": "   \n  "}` is a 201.
Promoting it ran `.strip().splitlines()[0]` over an empty list — IndexError.
The `or f"{key} {ref} review comment"` fallback written for exactly this case
had never been reachable at all: when the list is non-empty its first element
is never blank, so the `or` arm could not fire. The guard makes it live.

**Promotion idempotency was not atomic — and the damage is worse than a
duplicate.** `SessionLocal` is `expire_on_commit=False`, so a request that read
the comment before a concurrent promote committed keeps seeing a null back-link
for as long as it holds the session; the `if cm.topic_id` guard reads that stale
copy. A plain assignment then let the later writer overwrite the back-link,
minting a second RFI AND orphaning the first, whose Topic no comment pointed at
any more. The claim is now a conditional `UPDATE ... WHERE topic_id IS NULL`:
under Postgres read-committed the loser blocks on the winner's row lock and
re-evaluates the predicate against the committed row; under SQLite the writes
serialize to the same effect. Rolling back discards the Topic flushed a moment
earlier, so a losing promote leaves nothing behind.

The race test is deterministic rather than timing-dependent — the loser reads,
the winner commits, the loser proceeds from its stale identity map, which is the
production sequence. Mutation-checked both ways: restoring the unguarded index
raises IndexError, restoring the plain assignment fails "a stale-read promote
must be refused, not duplicated".

* R24-REPORTS-BY-MOMENT — a finished pack can be sent, not only downloaded

`POST /projects/{pid}/jobs/{job_id}/deliver` emails any finished job's artifact
to named recipients, surfaced as **Send** beside **Download** in the job tray.

**The roadmap named the wrong blocker, one layer too high.** The entry said
making a pack a scheduled deliverable "still wants a delivery surface and SMTP".
Both already existed when that was written: `mailer.py` sends real mail (stdlib
smtplib, a Settings "Test connection" button), and `POST …/notifications/digest`
is a working assemble-then-send surface returning a per-recipient status map.
What was actually missing was one size smaller — **the mailer could not carry a
file**. That is why the entry sat: the two things it named were present, so every
look confirmed it and nobody checked the layer below.

`build_message` gained attachments. The ORDER is load-bearing: `add_alternative`
must run before `add_attachment`, or the html body lands inside the mixed part —
Python's EmailMessage refuses outright ("Cannot convert mixed to alternative"),
which the test asserts rather than assumes.

Refusals mirror the download route exactly (404 wrong project, 409 while
queued/running, 404 with no artifact) so a caller does not learn two answers to
"is this artifact ready", plus two of delivery's own: an empty recipient list is
422 rather than a silent success, and over 15 MB is 413 rather than a
per-recipient error from a server that would have bounced it anyway. An
unconfigured deployment returns 200 with every recipient `disabled`, so the UI
reads `smtp_configured` before claiming a send. The delivery is audited — a file
leaving the system is what an audit log is for.

**Not shipped, deliberately: the SCHEDULED half.** There is no scheduler of any
kind in this tree — no APScheduler, no croniter, no cron — so the existing digest
is admin-triggered and nothing runs on a date. Choosing in-process versus
external cron hitting an endpoint is a deployment decision with different
operational consequences, not a wiring task. The roadmap now says that instead of
naming two things that already ship.

Mutation-checked, four ways on the route and one on the tray: dropping the
empty-recipient refusal reproduces the silent success it exists to prevent (200
with `"results":{}`); dropping the size cap admits 15 MB + 1; ignoring
attachments loses the file; attaching before the alternative raises; and ungating
Send from `hasArtifact` offers it on a job with nothing to send.

The client-caller gate did its job here — it failed the build because
`deliverJobArtifact` had no screen, which is what drove the job-tray wiring
rather than shipping another endpoint nobody can reach.

* Review round on #435: five findings, all verified real, all fixed

**1. A malformed recipient aborted the whole delivery (Major).** `send_email`
built the message BEFORE its try block. `EmailMessage` rejects a header value
containing CR/LF with ValueError, and this function is documented to never raise
— so one bad address raised out of the loop after earlier recipients had already
received the artifact and before the audit row was written, leaving the record
disagreeing with what happened. Construction moved inside the protected flow;
a bad address is now that recipient's "error" and nobody else's. Also built (and
discarded) on the unconfigured path, so a malformed address does not become
visible only in production.

**2. STARTTLS presented an unverified context (Major, CWE-295).** The finding's
stated reason was wrong — it said "Python 3.9 uses an unverified context" and
this repo is on 3.12 — but the conclusion holds on 3.12 too: measured,
`ssl._create_stdlib_context()` reports verify_mode=0 and check_hostname=False,
so the artifact and the SMTP password went up with no certificate check. Both
call sites now pass `ssl.create_default_context()`.

**3. The size cap ran AFTER materialising the object (Major).** `storage.get`
pulls the whole artifact into memory and `len(data)` checked it afterwards, so
the memory was already spent on exactly the payload being refused — and
concurrent callers multiply it. `storage.size(key)` already existed; the check
now runs before the read.

**4. Recipients were unbounded and undeduplicated (Major, CWE-770).** Each
address is a synchronous SMTP conversation with a 15-second timeout, so an
unbounded list occupies a worker for hours. Now de-duplicated case-insensitively
(preserving caller order) and capped at 25 — as a 422 refusal, not a silent trim,
because quietly dropping recipients is the same silent-success failure the
empty-list 422 exists to prevent.

**5. The test stole the runner's STORAGE_DIR (Minor).** `run_tests.py` assigns
`STORAGE_DIR=./_storage_{test}` and sweeps exactly that path; the test overwrote
it, so its 15 MiB blob landed somewhere the runner does not own. That is what the
suite footer's "dir(s) this runner does not own" counts, and the stray directory
was sitting on disk at 61 MB. Now `setdefault`.

Every fix is mutation-checked. Restoring the pre-fix code fails with: build
outside the try -> AssertionError on the per-recipient result map; size-after-read
-> "materialised <key>" from a patched storage.get, which proves the object was
pulled in; no cap -> 26 recipients accepted; no dedup -> a@ and A@ both served;
bare starttls() -> "called with no context — that context does NOT verify",
asserted through a fake SMTP that captures what is actually passed rather than by
reading the source.

* Second review round on #435: the port fix is the root cause my first fix missed

Three new findings on the fix commit. Two were real defects, one is a design
question answered rather than obeyed.

**A mistyped SMTP port escaped the no-raise boundary (Major) — and this is the
SAME defect class the previous commit fixed, one line above the guard.** That fix
moved `build_message` inside the try and left `int(AEC_SMTP_PORT)` outside it.
Settings are stored as arbitrary strings (`settings_store.set_value(db, k,
str(v))`, no numeric validation), so a typo in the Settings form raised
ValueError straight through a function documented never to raise, aborting the
delivery loop before its audit row — exactly the failure the CR/LF fix was for.
Treating the instance instead of the class is what left it. The whole prologue is
now inside the boundary: this function returns a status for ANY input,
configuration included.

**A recipient could forge log lines (Minor, CWE-117).** Both exception handlers
logged `to` with `%s`, so CR/LF in an address writes literal newlines into the
stream and a recipient can append a plausible-looking record of its own. Now
`%r`, which escapes them — the value is still reported, never as its own line.
This one was introduced by my previous commit, not found in old code.

**Cleartext SMTP auth: warned, not refused — deliberately.** The finding asks to
reject `send_email`/`smtp_test` outright when `AEC_SMTP_TLS=0`. That is a
documented deployment choice for a self-hosted product relaying through localhost
or a trusted internal MTA, where cleartext is not an exposure; hard-refusing
would break those installs to protect against a risk they do not have. What is
not defensible is doing it silently, so a credential sent without TLS now logs a
warning naming the setting and the remedy. The password is never logged, and the
test asserts that.

Mutation-checked: %s in place of %r puts the forged line back in the stream;
moving the port parse back outside the try loses the "error" status; removing the
warning loses the cleartext notice. The password assertion was rewritten after it
passed for the wrong reason — the fixture used "p" as the password and the
haystack was full of the letter p, so it now uses a distinctive value.

* SCALE-SEAM (95) — element state: two read/write pairs, and why the matrix loses

Moves `lodSummary`/`setLod` and `phasing`/`setPhase` out of `client.ts` into
`api/model.ts`. They answer one question — *what state are the model's elements
in, and set it?* — and `client.ts` goes 727 -> 711, 76 methods above the STAYING
banner.

The grouping is derived, not asserted:

- identical return shape `{ total, <x>ed, prop, counts: Record<...> }`;
- both writers are `(pid, guids, <enum>, publish) -> editIfc`;
- both readers are consumed by `viewer/tools/modelStatePanels.ts` (251, 316);
- both writers sit unwired and *adjacent* on `clientCallers.test.ts`'s UNCALLED
  allowlist;
- `model.ts` already owned `/model/lod/census`, `/lod/handover-readiness` and
  `/lod/assessment`, while the base distribution `/projects/{pid}/lod` was left
  behind in `client.ts` — `lodSummary` was a sibling separated from its family.

`authoring_matrix.py` DISAGREES and is recorded as the losing vote rather than
elided. It files `set_lod` under `data` and `set_phase` under `lifecycle`,
because it categorises by the IFC output each recipe writes — an LOD stage tag
against `Massing_Phasing.Status`. Different property sets, same question, which
is (89)'s "storage is a HOW" trap. This is the first slice where the matrix has
been wrong after being right three running.

It also MEETS (94)'s objection rather than overriding it: that slice declined
`setPhase` because taking the writer alone would have stranded `phasing()`, the
reader/writer split (87) had to undo. Both halves move together here.

The four names are added to `surface.test.ts` because its floor is a slack
ratchet (788 actual vs 751 floor) — the count alone would not notice a loss —
and because the UNCALLED allowlist is about call sites, not the surface.

* SCALE-SEAM (96) — the as-built question's aggregate reader, and a witness that actually bounds

Moves `lod500`, `setManufacturerInfo` and `attachOmDocument` out of `client.ts`
into `api/model.ts`, rejoining `verifyAsbuilt` and `recordAsbuiltDimension`
which (94) moved. `client.ts` goes 711 -> 698, 73 methods above the STAYING
banner.

TWO BOUNDING WITNESSES, derived independently, agreeing:

- `openAsBuiltPanel` in `viewer/tools/modelStatePanels.ts` calls exactly five
  API methods — read off that function's brace closure rather than grepped for,
  so it is the closure of a scope and not a sample. Two of the five were
  already in `model.ts`.
- The reader's own response type names its writer set field by field:
  `verified`/`by_method` from `verify_asbuilt`;
  `with_dimensions`/`dimensions_out_of_tolerance` from
  `record_asbuilt_dimension`; `with_manufacturer`/`with_serial` from
  `set_manufacturer_info`; `with_om_docs`/`om_documents` from
  `attach_om_document`. The backend route says it in prose: "Stamp elements
  with the `verify_asbuilt` recipe."

A reader whose response type enumerates its writers is a DERIVED population.
After eight slices of sampling, that is the first grouping witness here that
bounds a set instead of illustrating one.

WHAT CORROBORATES IS NOT WHAT BOUNDS. `test_lod500.py` reaches exactly three
recipes — `attach_om_document`, `set_manufacturer_info`, `verify_asbuilt` — and
OMITS `record_asbuilt_dimension`, which is unambiguously in this family. It
agrees with the answer without being able to establish it. Three slices claimed
"and no others" off a test file and were wrong all three times.

NOT CLAIMED, and said in the header, the pin, the changelog and the roadmap
rather than only in review: `attachDocument` stays in `client.ts`, takes a
`purpose` parameter, and `asbuilt_summary` counts ANY purpose-tagged document
reference — so "every writer of `with_om_docs` moves here" is false. The field
map is of the recipes each field was designed around, not of everything that
can set it.

Two sources disagree and lose for the same reason: `attach_om_document` is a
purpose-tagged wrapper of `detailing.attach_document`, and
`authoring_matrix.py` files it and `set_manufacturer_info` under `data`. The
first is a shared HELPER, the second a STORAGE bucket — the groupings (89) and
(90) each had to reject. The matrix is the losing vote twice running after
being right three times.

Also fixes the extraction helper: it terminated its brace count on the method
signature line, so a signature wrapping across two lines with no opening brace
on the first read as a 3-line method. `attachOmDocument` is 6.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* SCALE-SEAM (97) — the undo stack, and a destination that looked right and was not

Moves `editHistory`, `editUndo` and `editRedo` out of `client.ts` into
`api/authoring.ts`. `client.ts` goes 698 -> 687, 70 methods above the STAYING
banner.

WHY THAT MIXIN: `editIfc`, already there, is the PUSH they pop. `authoring.py`
records the pre-edit version on every `/edit` call "so this edit can be undone",
`_restore_version` pops that stack, and `edit_history.state()` reads its depths.
One stack, and the operation that fills it was already in this file.

The types agree: both writers return `{restored, state: {can_undo, can_redo}}`,
and `state` is `editHistory`'s own return type minus the depths — the writers
hand back the reader's answer. That is a type-level relation, not the shared
`/edit/` prefix. The prefix is real and is deliberately not the argument, since
a route prefix is exactly what the verification slice was caught grouping on.

A HYPOTHESIS TESTED AND WITHDRAWN, which is the part worth keeping. "Undo
restores the prior model version" makes `model.ts` the obvious home — it owns
`modelVersions`, `versionDiff`, `versionCostDelta`. It is the wrong home: those
read `/projects/{pid}/versions` out of `bim.py`, while undo pops a DIFFERENT
stack, the `edit_history` sidecar, which `recipe_log.py` describes as a list of
file paths with "No recipe, no parameters, no actor". Two stacks, one word — and
the word is what made the wrong answer look obvious. Second withdrawal of a
plausible destination after checking it, after (93) withdrew (92)'s `HttpCore`
forecast.

THE BOUND IS WEAKER THAN (96)'s AND IS STATED THAT WAY. `app.ts`'s S4 block
wires `refreshUndo` (calling only `editHistory`) and `doUndoRedo` (calling only
`editUndo`/`editRedo`), so the union is exactly these three — but that unit is a
block delimited by reading, not a closure the braces define. It corroborates; it
does not bound. Not every set has a witness as strong as the last one's, and
promoting a block to a closure would be this sequence's own recurring defect.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* Correct the undo/redo republish docs — all three sites, not just the flagged one

CodeRabbit flagged `editUndo`'s docstring on #414: it says "restore the prior
model version + republish" unconditionally, but `publish` defaults to true and
can be false. Verified against the backend — `_restore_version` guards the
republish with `if publish:` — so the claim is wrong whenever a caller passes
`publish: false`.

Grepping every site of that wording found the same unconditional claim in THREE
live places, not one:

- `apps/web/src/api/authoring.ts` — `editUndo` (the flagged one)
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/undo` route
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/redo` route

All three now say republishing happens only when `publish`. The remaining hits
are UI button labels, where the call site never passes the flag so republish
really is unconditional, and historical CHANGELOG entries; both are correct as
written and are left alone.

Also fixes the same defect's other half in the same five lines: the declared
return type omitted `publish`, which the backend adds as `"running"` when it
republishes. Correcting the prose while leaving the type silent about the same
conditional would be the half-applied fix this sequence has twice been caught
making.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, `test_file_sizes.py` 0.

* SCALE-SEAM (98) — detailing carriers, and a field map total over one module but not the codebase

Moves `elementDetailing`, `classify`, `applyDetailingRules`, `validateDetailing`
and `attachDocument` out of `client.ts` into a new `api/detailing.ts`.
`client.ts` goes 687 -> 665, 65 methods above the STAYING banner.

WHAT THEY ANSWER: what informational carriers are attached to this element,
write them, and which are missing?

THE WITNESS IS A 1:1 AND TOTAL FIELD-TO-WRITER MAP, the shape (96) established.
`element_detailing` walks `HasAssociations` and branches on exactly two
relationship types, and `detailing.py` holds exactly two writers, one per
response array:

  classifications[]  <-  classify        (IfcRelAssociatesClassification)
  documents[]        <-  attachDocument  (IfcRelAssociatesDocument)

The map is read out of the reader's own body, not matched on names. The other
two methods are those same writes automated and audited: `applyDetailingRules`
runs the condition-to-content rule set and writes both carrier kinds,
`validateDetailing` reports elements a rule applies to that lack the code.

TOTAL OVER THE MODULE, NOT THE CODEBASE, and the difference is the claim.
`attachOmDocument` — moved to `model.ts` in (96) — wraps the SAME
`detailing.attach_document` and also lands in `documents[]`, so "these are all
the writers of this reader's fields" is false. That overlap was recorded when it
moved, which is why it was on hand to qualify this slice rather than being found
in review.

ADJACENCY AGREED WITH THE ANSWER AND IS NOT EVIDENCE FOR IT. These five were
contiguous in `client.ts`; unlike (95), where non-contiguity was the whole
argument, a positional split would have found this set too. Stated precisely
because it looks like support.

ALSO RECORDED: `api.classify()` has no call site — `detailingSection.ts` drives
the recipe through the generic `authorAndReload` path, bypassing the typed
method, and `clientCallers.test.ts` counts it reached because it matches bare
string literals as well as calls. That looseness is deliberate per that file's
own docstring, so it is a limit of the gate rather than a defect in it.

The new mixin needs `editIfc`, so it declares `NeedsEditIfc` and composes
outside `withAuthoring`; `compositionOrder.test.ts` gains a fourth assertion.
MUTATION-CHECKED: relaxing the constraint to `Ctor<any>` produces "TS2578:
Unused '@ts-expect-error' directive" on exactly the new line, so it fails for
the reason claimed rather than merely passing.

The extraction removed 27 lines and the banner plus import added 5 back — caught
by the ratchet, not by me, the same way (94) found its own banner growth.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,

* SCALE-SEAM (99) — the content shelf, and a destination header that was wrong until now

Moves `contentCatalog`, `placeContent` and `importContent` out of `client.ts`
into `api/authoring.ts`. `client.ts` goes 665 -> 648, 62 methods above the
STAYING banner.

WHAT THEY ANSWER: what pre-made content can I place, and place it?

THE WITNESS IS A ROLE-FOR-ROLE PARALLEL with the family shelf already in that
file, read off the signatures rather than the shared noun:

  catalog reader    familyCatalog()  {count, categories: Record<..>}
                    contentCatalog() {count, note, groups: Record<..>}
  placer            placeFamily(pid, family, position)
                    placeContent(pid, category, point, name)
  multipart import  async importFamilies(pid, file, ..)
                    async importContent(pid, file, opts)

Three roles, three methods each, matching shapes and arities. A parallel between
two method TRIPLES is structural; "both are shelves" would have been a shared
word, which is the grouping (88) and (89) each had to reject.

THE DESTINATION'S OWN FIRST LINE WAS WRONG UNTIL THIS COMMIT. `authoring.ts` has
described itself as holding "the family/content shelf" while containing ZERO
content methods — the word's only other appearances there are an HTTP header and
a sentence about IFC *type* content. The docstring stated an intended scope as
fact.

That is recorded as corroboration that was FALSE, not as evidence. A header
agreeing with the answer is worth nothing until someone checks whether it is
true, and this one had been wrong for as long as it had existed. It is the
smallest possible instance of the drift the project instructions keep warning
about.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py` all 0.

* SCALE-SEAM (100) — the element-connection pair, and a destination named at its real strength

Moves `elementConnections` and `connectElements` out of `client.ts` into
`api/model.ts`. `client.ts` goes 648 -> 642, 60 methods above the STAYING
banner.

WHAT THEY ANSWER: what is physically joined to what, and record a joint?

THE PAIR IS BOUND BY THE BACKEND NAMING ITS OWN WRITER, the (96) shape: the
`/element-connections` route docstring reads "Author edges with the
`connect_elements` recipe (POST /edit with {guid_a, guid_b})". Reader and
writer, one relationship type (IfcRelConnectsElements), both marked B5.

THE DESTINATION ARGUMENT IS WEAKER THAN THE PAIRING ARGUMENT AND IS LABELLED SO.
`model.ts` owns `modelGraphStats`, whose `by_rel` counts the IFC relationship
graph BY RELATION — IfcRelConnectsElements being one — and `graphNeighbors`,
which walks it. So this pair is one relation of a graph the file already reads,
plus its authoring verb. That is a SPECIALISATION, not an identity: the graph
methods are generic traversal over every IfcRel*, these two are one relation
with a verb attached. The pairing is evidenced; the placement is a judgement,
and collapsing the two into one confident sentence is the overstatement this
sequence keeps catching.

TWO CANDIDATES REJECTED ON CHECKABLE GROUNDS. `connections.ts` is the trap: it
is DATA-SOURCE connections — SQL, ACC, Procore — sharing nothing with this but
the English word, and it is the file a name-based search lands on first. (97)
found two version stacks behind one word; this is the same collision in a
destination rather than a source. `elements.ts` holds element ATTRIBUTES and
views, and a relationship between two elements is not an attribute of either.

`addBasePlate`/`addShearTab` did not come despite sharing `connections.py` with
these: a backend module is a HOW, the grouping (89) had to reject, and those two
author PHYSICAL assemblies rather than relationship edges.

FOUND WHILE DERIVING, RECORDED NOT FIXED: `add_connection_assembly` (B5,
IfcRelConnectsWithRealizingElements) has no client method anywhere in
`apps/web/src` — a backend recipe with no web exposure, the class (93) recorded
for three MEP recipes.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* R22-ENTITLEMENT ⑤ — an agency review comment becomes an RFI somebody owns

`RecordComment` had NO outward link of any kind. An agency's comment on an
`entitlement` or `permit` was a text blob at the end of a thread: readable, and
impossible to assign, track or close. ④ made comments survive a revision — the
INBOUND half of "round-tripping"; this is the outbound half the ring entry still
listed as remaining.

`POST /projects/{pid}/modules/{key}/{rid}/comments/{cid}/promote` mints a Topic
carrying the comment text, the source record's ref and its `element_guids`, and
writes a back-link on the comment.

THE BACK-LINK IS THE IDEMPOTENCY. A second promote 409s instead of minting a
duplicate RFI — the failure mode a promote button produces on every
double-click. Both load-bearing assertions in `test_comment_promote.py` were
MUTATION-CHECKED: removing the 409 guard makes one comment mint two RFIs (the
failure output shows both `comment.promote` activity entries), and removing the
back-link write drops `topic_id` from the comment.

Follows `promote_markup` rather than inventing a second idiom — mint, carry
provenance, link back, 409, audit.

REACHABLE, NOT MERELY BUILT: the control renders beside the comment and is
replaced by "→ RFI raised" once promoted, because a button whose only remaining
outcome is a 409 is worse than no button.

Adding it turned `register.ts`'s extraction ratchet red, and the remedy is the
one that file states — extraction, never headroom. The comment thread, composer
and new control came out to `portal/register/recordComments.ts` (2,516 -> 2,505,
pin lowered with it). A genuine leaf: it touches the record's comments, the API
and a reload callback and nothing else on the class, and the directory already
holds three leaves extracted the same way.

WHAT THE PREMISE-CHECK FOUND, and it is why this slice exists. The entry's
"Remaining:" line named two things and contradicted itself on one — it listed
submittal packages flatly while the note above it said the inbound half had
shipped. Measured: the inbound view is real, but assembling a package to send is
not, because `modules/transmittal/module.json` types `items` as a textarea and
`to_company` as plain text. Package contents are prose no machine can resolve
back to the records named, and the recipient cannot be the agency an
`entitlement` names, since that is free text too. That is a SCHEMA question, not
a workflow one — which is why reading the workflow surface kept reporting it
done. The roadmap now says that instead of the flat line.

Also corrected: the roadmap's argument against picking SCALE-SEAM quoted
`client.ts` at 2,837 lines. It is 642 — copied forward through every slice since,
the exact drift the rows beside it document twice.

Verified: tsc 0, lint 0, build 0, `vitest run src/portal src/api` 50 files / 275
tests, ruff (the CI command, from `services/api`) 0, and `test_comment_promote`,
`test_modules`, `test_topic_lifecycle`, `test_reachable`, `test_declared_imports`,
`test_ruff_scope`, `test_file_sizes`, `test_claude_md_gates`,

Full 660-suite running as a cross-check.

* R22-ENTITLEMENT ⑤ review: promotion claims the comment atomically, and a blank one no longer 500s

Two findings on #434, both reproduced before fixing and both mutation-checked after.

**A whitespace-only comment 500s on promote.** The comment route takes
`text: str = Body(...)` with no min-length, so `{"text": "   \n  "}` is a 201.
Promoting it ran `.strip().splitlines()[0]` over an empty list — IndexError.
The `or f"{key} {ref} review comment"` fallback written for exactly this case
had never been reachable at all: when the list is non-empty its first element
is never blank, so the `or` arm could not fire. The guard makes it live.

**Promotion idempotency was not atomic — and the damage is worse than a
duplicate.** `SessionLocal` is `expire_on_commit=False`, so a request that read
the comment before a concurrent promote committed keeps seeing a null back-link
for as long as it holds the session; the `if cm.topic_id` guard reads that stale
copy. A plain assignment then let the later writer overwrite the back-link,
minting a second RFI AND orphaning the first, whose Topic no comment pointed at
any more. The claim is now a conditional `UPDATE ... WHERE topic_id IS NULL`:
under Postgres read-committed the loser blocks on the winner's row lock and
re-evaluates the predicate against the committed row; under SQLite the writes
serialize to the same effect. Rolling back discards the Topic flushed a moment
earlier, so a losing promote leaves nothing behind.

The race test is deterministic rather than timing-dependent — the loser reads,
the winner commits, the loser proceeds from its stale identity map, which is the
production sequence. Mutation-checked both ways: restoring the unguarded index
raises IndexError, restoring the plain assignment fails "a stale-read promote
must be refused, not duplicated".

* R24-REPORTS-BY-MOMENT — a finished pack can be sent, not only downloaded

`POST /projects/{pid}/jobs/{job_id}/deliver` emails any finished job's artifact
to named recipients, surfaced as **Send** beside **Download** in the job tray.

**The roadmap named the wrong blocker, one layer too high.** The entry said
making a pack a scheduled deliverable "still wants a delivery surface and SMTP".
Both already existed when that was written: `mailer.py` sends real mail (stdlib
smtplib, a Settings "Test connection" button), and `POST …/notifications/digest`
is a working assemble-then-send surface returning a per-recipient status map.
What was actually missing was one size smaller — **the mailer could not carry a
file**. That is why the entry sat: the two things it named were present, so every
look confirmed it and nobody checked the layer below.

`build_message` gained attachments. The ORDER is load-bearing: `add_alternative`
must run before `add_attachment`, or the html body lands inside the mixed part —
Python's EmailMessage refuses outright ("Cannot convert mixed to alternative"),
which the test asserts rather than assumes.

Refusals mirror the download route exactly (404 wrong project, 409 while
queued/running, 404 with no artifact) so a caller does not learn two answers to
"is this artifact ready", plus two of delivery's own: an empty recipient list is
422 rather than a silent success, and over 15 MB is 413 rather than a
per-recipient error from a server that would have bounced it anyway. An
unconfigured deployment returns 200 with every recipient `disabled`, so the UI
reads `smtp_configured` before claiming a send. The delivery is audited — a file
leaving the system is what an audit log is for.

**Not shipped, deliberately: the SCHEDULED half.** There is no scheduler of any
kind in this tree — no APScheduler, no croniter, no cron — so the existing digest
is admin-triggered and nothing runs on a date. Choosing in-process versus
external cron hitting an endpoint is a deployment decision with different
operational consequences, not a wiring task. The roadmap now says that instead of
naming two things that already ship.

Mutation-checked, four ways on the route and one on the tray: dropping the
empty-recipient refusal reproduces the silent success it exists to prevent (200
with `"results":{}`); dropping the size cap admits 15 MB + 1; ignoring
attachments loses the file; attaching before the alternative raises; and ungating
Send from `hasArtifact` offers it on a job with nothing to send.

The client-caller gate did its job here — it failed the build because
`deliverJobArtifact` had no screen, which is what drove the job-tray wiring
rather than shipping another endpoint nobody can reach.

* Review round on #435: five findings, all verified real, all fixed

**1. A malformed recipient aborted the whole delivery (Major).** `send_email`
built the message BEFORE its try block. `EmailMessage` rejects a header value
containing CR/LF with ValueError, and this function is documented to never raise
— so one bad address raised out of the loop after earlier recipients had already
received the artifact and before the audit row was written, leaving the record
disagreeing with what happened. Construction moved inside the protected flow;
a bad address is now that recipient's "error" and nobody else's. Also built (and
discarded) on the unconfigured path, so a malformed address does not become
visible only in production.

**2. STARTTLS presented an unverified context (Major, CWE-295).** The finding's
stated reason was wrong — it said "Python 3.9 uses an unverified context" and
this repo is on 3.12 — but the conclusion holds on 3.12 too: measured,
`ssl._create_stdlib_context()` reports verify_mode=0 and check_hostname=False,
so the artifact and the SMTP password went up with no certificate check. Both
call sites now pass `ssl.create_default_context()`.

**3. The size cap ran AFTER materialising the object (Major).** `storage.get`
pulls the whole artifact into memory and `len(data)` checked it afterwards, so
the memory was already spent on exactly the payload being refused — and
concurrent callers multiply it. `storage.size(key)` already existed; the check
now runs before the read.

**4. Recipients were unbounded and undeduplicated (Major, CWE-770).** Each
address is a synchronous SMTP conversation with a 15-second timeout, so an
unbounded list occupies a worker for hours. Now de-duplicated case-insensitively
(preserving caller order) and capped at 25 — as a 422 refusal, not a silent trim,
because quietly dropping recipients is the same silent-success failure the
empty-list 422 exists to prevent.

**5. The test stole the runner's STORAGE_DIR (Minor).** `run_tests.py` assigns
`STORAGE_DIR=./_storage_{test}` and sweeps exactly that path; the test overwrote
it, so its 15 MiB blob landed somewhere the runner does not own. That is what the
suite footer's "dir(s) this runner does not own" counts, and the stray directory
was sitting on disk at 61 MB. Now `setdefault`.

Every fix is mutation-checked. Restoring the pre-fix code fails with: build
outside the try -> AssertionError on the per-recipient result map; size-after-read
-> "materialised <key>" from a patched storage.get, which proves the object was
pulled in; no cap -> 26 recipients accepted; no dedup -> a@ and A@ both served;
bare starttls() -> "called with no context — that context does NOT verify",
asserted through a fake SMTP that captures what is actually passed rather than by
reading the source.

* Second review round on #435: the port fix is the root cause my first fix missed

Three new findings on the fix commit. Two were real defects, one is a design
question answered rather than obeyed.

**A mistyped SMTP port escaped the no-raise boundary (Major) — and this is the
SAME defect class the previous commit fixed, one line above the guard.** That fix
moved `build_message` inside the try and left `int(AEC_SMTP_PORT)` outside it.
Settings are stored as arbitrary strings (`settings_store.set_value(db, k,
str(v))`, no numeric validation), so a typo in the Settings form raised
ValueError straight through a function documented never to raise, aborting the
delivery loop before its audit row — exactly the failure the CR/LF fix was for.
Treating the instance instead of the class is what left it. The whole prologue is
now inside the boundary: this function returns a status for ANY input,
configuration included.

**A recipient could forge log lines (Minor, CWE-117).** Both exception handlers
logged `to` with `%s`, so CR/LF in an address writes literal newlines into the
stream and a recipient can append a plausible-looking record of its own. Now
`%r`, which escapes them — the value is still reported, never as its own line.
This one was introduced by my previous commit, not found in old code.

**Cleartext SMTP auth: warned, not refused — deliberately.** The finding asks to
reject `send_email`/`smtp_test` outright when `AEC_SMTP_TLS=0`. That is a
documented deployment choice for a self-hosted product relaying through localhost
or a trusted internal MTA, where cleartext is not an exposure; hard-refusing
would break those installs to protect against a risk they do not have. What is
not defensible is doing it silently, so a credential sent without TLS now logs a
warning naming the setting and the remedy. The password is never logged, and the
test asserts that.

Mutation-checked: %s in place of %r puts the forged line back in the stream;
moving the port parse back outside the try loses the "error" status; removing the
warning loses the cleartext notice. The password assertion was rewritten after it
passed for the wrong reason — the fixture used "p" as the password and the
haystack was full of the letter p, so it now uses a distinctive value.

* Only committed capital owns anything — cap table and waterfall

`capital.cap_table` summed `commitment` across every investor whatever their
workflow state. A `prospect` carrying a $10M interest and $0 contributed took
50% of a $10M cap table and halved a real LP from 60% to 30%. It did not stop at
display: `distwaterfall` allocates `share = lp_total * (commitment / lp_commit)`
off these rows, so the prospect drew **$1,818,181.82 of a $2M distribution**
while the committed LP got $181,818.18.

**The obvious filter is wrong on its own, which is why this took a guard.**
`investor` declares `initial: prospect` and every record is stamped with it at
creation, so on a project where nobody ran the `commit` transition EVERY investor
is a prospect and filtering empties the cap table. The roadmap records this was
implemented once and made `test_distwaterfall` return 0.0 instead of $2,000,000.

`workflow_in_use` separates two readings of the same value: **a default state is
not a signal.** Until some investor has moved off the stamped initial state,
`prospect` means "nobody used the workflow" and everyone counts, exactly as
before. Once one has, `prospect` means "not committed" and the state is evidence.

Of the three options the roadmap put to the owner, this is (c). (b) — keying on
`contributed > 0` — was rejected as a domain error: in an uncalled fund an LP
with a signed commitment and no contribution yet is normal, and that rule would
zero out real LPs who simply have not been called. (a) — changing the initial
state — needs a data migration and rewires the default entry path.

Prospect rows are never dropped: they stay visible at 0%, their money reported as
`pipeline_commitment`, and they no longer sort above real owners, because rank in
a cap table reads as ownership. `by_class` follows the same denominator or the
two halves of one table contradict. The decision rides on each row as
`counts_toward_ownership` rather than being re-derived by each of seven consumers.
`exited` is evidence the workflow was used, but is not current ownership.

Mutation-checked, and one mutation earned its keep: removing the filter restores
30%/50%; dropping the `workflow_in_use` guard reproduces the recorded failure
(`test_distwaterfall` -> 0.0); and making `distwaterfall` ignore the flag was
initially NOT caught, because `test_distwaterfall`'s fixture has no prospect. That
gap is now covered through the real API, and the mutation fails with the
$1.8M-to-the-prospect split above.

* SCALE-SEAM (95) — element state: two read/write pairs, and why the matrix loses

Moves `lodSummary`/`setLod` and `phasing`/`setPhase` out of `client.ts` into
`api/model.ts`. They answer one question — *what state are the model's elements
in, and set it?* — and `client.ts` goes 727 -> 711, 76 methods above the STAYING
banner.

The grouping is derived, not asserted:

- identical return shape `{ total, <x>ed, prop, counts: Record<...> }`;
- both writers are `(pid, guids, <enum>, publish) -> editIfc`;
- both readers are consumed by `viewer/tools/modelStatePanels.ts` (251, 316);
- both writers sit unwired and *adjacent* on `clientCallers.test.ts`'s UNCALLED
  allowlist;
- `model.ts` already owned `/model/lod/census`, `/lod/handover-readiness` and
  `/lod/assessment`, while the base distribution `/projects/{pid}/lod` was left
  behind in `client.ts` — `lodSummary` was a sibling separated from its family.

`authoring_matrix.py` DISAGREES and is recorded as the losing vote rather than
elided. It files `set_lod` under `data` and `set_phase` under `lifecycle`,
because it categorises by the IFC output each recipe writes — an LOD stage tag
against `Massing_Phasing.Status`. Different property sets, same question, which
is (89)'s "storage is a HOW" trap. This is the first slice where the matrix has
been wrong after being right three running.

It also MEETS (94)'s objection rather than overriding it: that slice declined
`setPhase` because taking the writer alone would have stranded `phasing()`, the
reader/writer split (87) had to undo. Both halves move together here.

The four names are added to `surface.test.ts` because its floor is a slack
ratchet (788 actual vs 751 floor) — the count alone would not notice a loss —
and because the UNCALLED allowlist is about call sites, not the surface.

* SCALE-SEAM (96) — the as-built question's aggregate reader, and a witness that actually bounds

Moves `lod500`, `setManufacturerInfo` and `attachOmDocument` out of `client.ts`
into `api/model.ts`, rejoining `verifyAsbuilt` and `recordAsbuiltDimension`
which (94) moved. `client.ts` goes 711 -> 698, 73 methods above the STAYING
banner.

TWO BOUNDING WITNESSES, derived independently, agreeing:

- `openAsBuiltPanel` in `viewer/tools/modelStatePanels.ts` calls exactly five
  API methods — read off that function's brace closure rather than grepped for,
  so it is the closure of a scope and not a sample. Two of the five were
  already in `model.ts`.
- The reader's own response type names its writer set field by field:
  `verified`/`by_method` from `verify_asbuilt`;
  `with_dimensions`/`dimensions_out_of_tolerance` from
  `record_asbuilt_dimension`; `with_manufacturer`/`with_serial` from
  `set_manufacturer_info`; `with_om_docs`/`om_documents` from
  `attach_om_document`. The backend route says it in prose: "Stamp elements
  with the `verify_asbuilt` recipe."

A reader whose response type enumerates its writers is a DERIVED population.
After eight slices of sampling, that is the first grouping witness here that
bounds a set instead of illustrating one.

WHAT CORROBORATES IS NOT WHAT BOUNDS. `test_lod500.py` reaches exactly three
recipes — `attach_om_document`, `set_manufacturer_info`, `verify_asbuilt` — and
OMITS `record_asbuilt_dimension`, which is unambiguously in this family. It
agrees with the answer without being able to establish it. Three slices claimed
"and no others" off a test file and were wrong all three times.

NOT CLAIMED, and said in the header, the pin, the changelog and the roadmap
rather than only in review: `attachDocument` stays in `client.ts`, takes a
`purpose` parameter, and `asbuilt_summary` counts ANY purpose-tagged document
reference — so "every writer of `with_om_docs` moves here" is false. The field
map is of the recipes each field was designed around, not of everything that
can set it.

Two sources disagree and lose for the same reason: `attach_om_document` is a
purpose-tagged wrapper of `detailing.attach_document`, and
`authoring_matrix.py` files it and `set_manufacturer_info` under `data`. The
first is a shared HELPER, the second a STORAGE bucket — the groupings (89) and
(90) each had to reject. The matrix is the losing vote twice running after
being right three times.

Also fixes the extraction helper: it terminated its brace count on the method
signature line, so a signature wrapping across two lines with no opening brace
on the first read as a 3-line method. `attachOmDocument` is 6.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py`, `test_ruff_scope.py`,

* SCALE-SEAM (97) — the undo stack, and a destination that looked right and was not

Moves `editHistory`, `editUndo` and `editRedo` out of `client.ts` into
`api/authoring.ts`. `client.ts` goes 698 -> 687, 70 methods above the STAYING
banner.

WHY THAT MIXIN: `editIfc`, already there, is the PUSH they pop. `authoring.py`
records the pre-edit version on every `/edit` call "so this edit can be undone",
`_restore_version` pops that stack, and `edit_history.state()` reads its depths.
One stack, and the operation that fills it was already in this file.

The types agree: both writers return `{restored, state: {can_undo, can_redo}}`,
and `state` is `editHistory`'s own return type minus the depths — the writers
hand back the reader's answer. That is a type-level relation, not the shared
`/edit/` prefix. The prefix is real and is deliberately not the argument, since
a route prefix is exactly what the verification slice was caught grouping on.

A HYPOTHESIS TESTED AND WITHDRAWN, which is the part worth keeping. "Undo
restores the prior model version" makes `model.ts` the obvious home — it owns
`modelVersions`, `versionDiff`, `versionCostDelta`. It is the wrong home: those
read `/projects/{pid}/versions` out of `bim.py`, while undo pops a DIFFERENT
stack, the `edit_history` sidecar, which `recipe_log.py` describes as a list of
file paths with "No recipe, no parameters, no actor". Two stacks, one word — and
the word is what made the wrong answer look obvious. Second withdrawal of a
plausible destination after checking it, after (93) withdrew (92)'s `HttpCore`
forecast.

THE BOUND IS WEAKER THAN (96)'s AND IS STATED THAT WAY. `app.ts`'s S4 block
wires `refreshUndo` (calling only `editHistory`) and `doUndoRedo` (calling only
`editUndo`/`editRedo`), so the union is exactly these three — but that unit is a
block delimited by reading, not a closure the braces define. It corroborates; it
does not bound. Not every set has a witness as strong as the last one's, and
promoting a block to a closure would be this sequence's own recurring defect.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* Correct the undo/redo republish docs — all three sites, not just the flagged one

CodeRabbit flagged `editUndo`'s docstring on #414: it says "restore the prior
model version + republish" unconditionally, but `publish` defaults to true and
can be false. Verified against the backend — `_restore_version` guards the
republish with `if publish:` — so the claim is wrong whenever a caller passes
`publish: false`.

Grepping every site of that wording found the same unconditional claim in THREE
live places, not one:

- `apps/web/src/api/authoring.ts` — `editUndo` (the flagged one)
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/undo` route
- `services/api/src/aec_api/routers/authoring.py` — the `/edit/redo` route

All three now say republishing happens only when `publish`. The remaining hits
are UI button labels, where the call site never passes the flag so republish
really is unconditional, and historical CHANGELOG entries; both are correct as
written and are left alone.

Also fixes the same defect's other half in the same five lines: the declared

republishes. Correcting the prose while leaving the type silent about the same

making.

* SCALE-SEAM (98) — detailing carriers, and a field map total over one module but not the codebase

Moves `elementDetailing`, `classify`, `applyDetailingRules`, `validateDetailing`
and `attachDocument` out of `client.ts` into a new `api/detailing.ts`.
`client.ts` goes 687 -> 665, 65 methods above the STAYING banner.

WHAT THEY ANSWER: what informational carriers are attached to this element,
write them, and which are missing?

THE WITNESS IS A 1:1 AND TOTAL FIELD-TO-WRITER MAP, the shape (96) established.
`element_detailing` walks `HasAssociations` and branches on exactly two
relationship types, and `detailing.py` holds exactly two writers, one per
response array:

  classifications[]  <-  classify        (IfcRelAssociatesClassification)
  documents[]        <-  attachDocument  (IfcRelAssociatesDocument)

The map is read out of the reader's own body, not matched on names. The other
two methods are those same writes automated and audited: `applyDetailingRules`
runs the condition-to-content rule set and writes both carrier kinds,
`validateDetailing` reports elements a rule applies to that lack the code.

TOTAL OVER THE MODULE, NOT THE CODEBASE, and the difference is the claim.
`attachOmDocument` — moved to `model.ts` in (96) — wraps the SAME
`detailing.attach_document` and also lands in `documents[]`, so "these are all
the writers of this reader's fields" is false. That overlap was recorded when it
moved, which is why it was on hand to qualify this slice rather than being found
in review.

ADJACENCY AGREED WITH THE ANSWER AND IS NOT EVIDENCE FOR IT. These five were
contiguous in `client.ts`; unlike (95), where non-contiguity was the whole
argument, a positional split would have found this set too. Stated precisely
because it looks like support.

ALSO RECORDED: `api.classify()` has no call site — `detailingSection.ts` drives
the recipe through the generic `authorAndReload` path, bypassing the typed
method, and `clientCallers.test.ts` counts it reached because it matches bare
string literals as well as calls. That looseness is deliberate per that file's
own docstring, so it is a limit of the gate rather than a defect in it.

The new mixin needs `editIfc`, so it declares `NeedsEditIfc` and composes
outside `withAuthoring`; `compositionOrder.test.ts` gains a fourth assertion.
MUTATION-CHECKED: relaxing the constraint to `Ctor<any>` produces "TS2578:
Unused '@ts-expect-error' directive" on exactly the new line, so it fails for
the reason claimed rather than merely passing.

The extraction removed 27 lines and the banner plus import added 5 back — caught
by the ratchet, not by me, the same way (94) found its own banner growth.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,

* SCALE-SEAM (99) — the content shelf, and a destination header that was wrong until now

Moves `contentCatalog`, `placeContent` and `importContent` out of `client.ts`
into `api/authoring.ts`. `client.ts` goes 665 -> 648, 62 methods above the
STAYING banner.

WHAT THEY ANSWER: what pre-made content can I place, and place it?

THE WITNESS IS A ROLE-FOR-ROLE PARALLEL with the family shelf already in that
file, read off the signatures rather than the shared noun:

  catalog reader    familyCatalog()  {count, categories: Record<..>}
                    contentCatalog() {count, note, groups: Record<..>}
  placer            placeFamily(pid, family, position)
                    placeContent(pid, category, point, name)
  multipart import  async importFamilies(pid, file, ..)
                    async importContent(pid, file, opts)

Three roles, three methods each, matching shapes and arities. A parallel between
two method TRIPLES is structural; "both are shelves" would have been a shared
word, which is the grouping (88) and (89) each had to reject.

THE DESTINATION'S OWN FIRST LINE WAS WRONG UNTIL THIS COMMIT. `authoring.ts` has
described itself as holding "the family/content shelf" while containing ZERO
content methods — the word's only other appearances there are an HTTP header and
a sentence about IFC *type* content. The docstring stated an intended scope as
fact.

That is recorded as corroboration that was FALSE, not as evidence. A header
agreeing with the answer is worth nothing until someone checks whether it is
true, and this one had been wrong for as long as it had existed. It is the
smallest possible instance of the drift the project instructions keep warning
about.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py` all 0.

* SCALE-SEAM (100) — the element-connection pair, and a destination named at its real strength

Moves `elementConnections` and `connectElements` out of `client.ts` into
`api/model.ts`. `client.ts` goes 648 -> 642, 60 methods above the STAYING
banner.

WHAT THEY ANSWER: what is physically joined to what, and record a joint?

THE PAIR IS BOUND BY THE BACKEND NAMING ITS OWN WRITER, the (96) shape: the
`/element-connections` route docstring reads "Author edges with the
`connect_elements` recipe (POST /edit with {guid_a, guid_b})". Reader and
writer, one relationship type (IfcRelConnectsElements), both marked B5.

THE DESTINATION ARGUMENT IS WEAKER THAN THE PAIRING ARGUMENT AND IS LABELLED SO.
`model.ts` owns `modelGraphStats`, whose `by_rel` counts the IFC relationship
graph BY RELATION — IfcRelConnectsElements being one — and `graphNeighbors`,
which walks it. So this pair is one relation of a graph the file already reads,
plus its authoring verb. That is a SPECIALISATION, not an identity: the graph
methods are generic traversal over every IfcRel*, these two are one relation
with a verb attached. The pairing is evidenced; the placement is a judgement,
and collapsing the two into one confident sentence is the overstatement this
sequence keeps catching.

TWO CANDIDATES REJECTED ON CHECKABLE GROUNDS. `connections.ts` is the trap: it
is DATA-SOURCE connections — SQL, ACC, Procore — sharing nothing with this but
the English word, and it is the file a name-based search lands on first. (97)
found two version stacks behind one word; this is the same collision in a
destination rather than a source. `elements.ts` holds element ATTRIBUTES and
views, and a relationship between two elements is not an attribute of either.

`addBasePlate`/`addShearTab` did not come despite sharing `connections.py` with
these: a backend module is a HOW, the grouping (89) had to reject, and those two
author PHYSICAL assemblies rather than relationship edges.

FOUND WHILE DERIVING, RECORDED NOT FIXED: `add_connection_assembly` (B5,
IfcRelConnectsWithRealizingElements) has no client method anywhere in
`apps/web/src` — a backend recipe with no web exposure, the class (93) recorded
for three MEP recipes.

Verified: tsc 0, lint 0, `vitest run src/api` 27 files / 119 tests, build 0,
ruff (the CI command, from `services/api`) 0, and `test_file_sizes.py`,
`test_claude_md_gates.py`, `test_roadmap_status.py` all 0.

* R22-ENTITLEMENT ⑤ — an agency review comment becomes an RFI somebody owns

`RecordComment` had NO outward link of any kind. An agency's comment on an
`entitlement` or `permit` was a text blob at the end of a thread: readable, and
impossible to assign, track or close. ④ made comments survive a revision — the
INBOUND half of "round-tripping"; this is the outbound half the ring entry still
listed as remaining.

`POST /projects/{pid}/modules/{key}/{rid}/comments/{cid}/promote` mints a Topic
carrying the comment text, the source record's ref and its `element_guids`, and
writes a back-link on the comment.

THE BACK-LINK IS THE IDEMPOTENCY. A second promote 409s instead of minting a
duplicate RFI — the failure mode a promote button produces on every
double-click. Both load-bearing assertions in `test_comment_promote.py` were
MUTATION-CHECKED: removing the 409 guard makes one comment mint two RFIs (the
failure output shows both `comment.promote` activity entries), and removing the
back-link write drops `topic_id` from the comment.

Follows `promote_markup` rather than inventing a second idiom — mint, carry
provenance, link back, 409, audit.

REACHABLE, NOT MERELY BUILT: the control renders beside the comment and is
replaced by "→ RFI raised" once promoted, because a button whose only remaining
outcome is a 409 is worse than no button.

Adding it turned `register.ts`'s extraction ratchet red, and the remedy is the
one that file states — extraction, never headroom. The comment thread, composer
and new control came out to `portal/register/recordComments.ts` (2,516 -> 2,505,
pin lowered with it). A genuine leaf: it touches the record's comments, the API
and a reload callback and nothing else on the class, and the directory already
holds three leaves extracted the same way.

WHAT THE PREMISE-CHECK FOUND, and it is why this slice exists. The entry's
"Remaining:" line named two things and contradicted itself on one — it listed
submittal packages flatly while the note above it said the inbound half had
shipped. Measured: the inbound view is real, but assembling a package to send is
not, because `modules/transmittal/module.json` types `items` as a textarea and
`to_company` as plain text. Package contents are prose no machine can resolve
back to the records named, and the recipient cannot be the agency an
`entitlement` names, since that is free text too. That is a SCHEMA question, not
a workflow one — which is why reading the workflow surface kept reporting it
done. The roadmap now says that instead of the flat line.

Also corrected: the roadmap's argument against picking SCALE-SEAM quoted
`client.ts` at 2,837 lines. It is 642 — copied forward through every slice since,
the exact drift the rows beside it document twice.

Verified: tsc 0, lint 0, build 0, `vitest run src/portal src/api` 50 files / 275
tests, ruff (the CI command, from `services/api`) 0, and `test_comment_promote`,
`test_modules`, `test_topic_lifecycle`, `test_reachable`, `test_declared_imports`,
`test_ruff_scope`, `test_file_sizes`, `test_claude_md_gates`,
`test_roadmap_status`, `test_doc_substance`, `test_alembic_single_head` all 0.
Full 660-suite running as a cross-check.

* R22-ENTITLEMENT ⑤ review: promotion claims the comment atomically, and a blank one no longer 500s

Two findings on #434, both reproduced before fixing and both mutation-checked after.

**A whitespace-only comment 500s on promote.** The comment route takes
`text: str = Body(...)` with no min-length, so `{"text": "   \n  "}` is a 201.
Promoting it ran `.strip().splitlines()[0]` over an empty list — IndexError.
The `or f"{key} {ref} review comment"` fallback written for exactly this case
had never been reachable at all: when the list is non-empty its first element
is never blank, so the `or` arm could not fire. The guard makes it live.

**Promotion idempotency was not atomic — and the damage is worse than a
duplicate.** `SessionLocal` is `expire_on_commit=False`, so a request that read
the comment before a concurrent promote committed keeps seeing a null back-link
for as long as it holds the session; the `if cm.topic_id` guard reads that stale
copy. A plain assignment then let the later writer overwrite the back-link,
minting a second RFI AND orphaning the first, whose Topic no comment pointed at
any more. The claim is now a conditional `UPDATE ... WHERE topic_id IS NULL`:
under Postgres read-committed the loser blocks on the winner's row lock and
re-evaluates the predicate against the committed row; under SQLite the writes
serialize to the same effect. Rolling back discards the Topic flushed a moment
earlier, so a losing promote leaves nothing behind.

The race test is deterministic rather than timing-dependent — the loser reads,
the winner commits, the loser proceeds from its stale identity map, which is the
production sequence. Mutation-checked both ways: restoring the unguarded index
raises IndexError, restoring the plain assignment fails "a stale-read promote
must be refused, not duplicated".

* R24-REPORTS-BY-MOMENT — a finished pack can be sent, not only downloaded

`POST /projects/{pid}/jobs/{job_id}/deliver` emails any finished job's artifact
to named recipients, surfaced as **Send** beside **Download** in the job tray.

**The roadmap named the wrong blocker, one layer too high.** The entry said
making a pack a scheduled deliverable "still wants a delivery surface and SMTP".
Both already existed when that was written: `mailer.py` sends real mail (stdlib
smtplib, a Settings "Test connection" button), and `POST …/notifications/digest`
is a working assemble-then-send surface returning a per-recipient status map.
What was actually missing was one size smaller — **the mailer could not carry a
file**. That is why the entry sat: the two things it named were present, so every
look confirmed it and nobody checked the layer below.

`build_message` gained attachments. The ORDER is load-bearing: `add_alternative`
must run before `add_attachment`, or the html body lands inside the mixed part —
Python's EmailMessage refuses outright ("Cannot convert mixed to alternative"),
which the test asserts rather than assumes.

Refusals mirror the download route exactly (404 wrong project, 409 while
queued/running, 404 with no artifact) so a caller does not learn two answers to
"is this artifact ready", plus two of delivery's own: an empty recipient list is
422 rather than a silent success, and over 15 MB is 413 rather than a
per-recipient error from a server that would have bounced it anyway. An
unconfigured deployment returns 200 with every recipient `disabled`, so the UI
reads `smtp_configured` before claiming a send. The delivery is audited — a file
leaving the system is what an audit log is for.

**Not shipped, deliberately: the SCHEDULED half.** There is no scheduler of any
kind in this tree — no APScheduler, no croniter, no cron — so the existing digest
is admin-triggered and nothing runs on a date. Choosing in-process versus
external cron hitting an endpoint is a deployment decision with different
operational consequences, not a wiring task. The roadmap now says that instead of
naming two things that already ship.

Mutation-checked, four ways on the route and one on the tray: dropping the
empty-recipient refusal reproduces the silent success it exists to prevent (200
with `"results":{}`); dropping the size cap admits 15 MB + 1; ignoring
attachments loses the file; attaching before the alternative raises; and ungating
Send from `hasArtifact` offers it on a job with nothing to send.

The client-caller gate did its job here — it failed the build because
`deliverJobArtifact` had no screen, which is what drove the job-tray wiring
rather than shipping another endpoint nobody can reach.

* Review round on #435: five findings, all verified real, all fixed

**1. A malformed recipient aborted the whole delivery (Major).** `send_email`
built the message BEFORE its try block. `EmailMessage` rejects a header value
containing CR/LF with ValueError, and this function is documented to never raise
— so one bad address raised out of the loop after earlier recipients had already
received the artifact and before the audit row was written, leaving the record
disagreeing with what happened. Construction moved inside the protected flow;
a bad address is now that recipient's "error" and nobody else's. Also built (and
discarded) on the unconfigured path, so a malformed address does not become
visible only in production.

**2. STARTTLS presented an unverified context (Major, CWE-295).** The finding's
stated reason was wrong — it said "Python 3.9 uses an unverified context" and
this repo is on 3.12 — but the conclusion holds on 3.12 too: measured,
`ssl._create_stdlib_context()` reports verify_mode=0 and check_hostname=False,
so the artifact and the SMTP password went up with no certificate check. Both
call sites now pass `ssl.create_default_context()`.

**3. The size cap ran AFTER materialising the object (Major).** `storage.get`
pulls the whole artifact into memory and `len(data)` checked it afterwards, so
the memory was already spent on exactly the payload being refused — and
concurrent callers multiply it. `storage.size(key)` already existed; the check
now runs before the read.

**4. Recipients were unbounded and undeduplicated (Major, CWE-770).** Each
address is a synchronous SMTP conversation with a 15-second timeout, so an
unbounded list occupies a worker for hours. Now de-duplicated case-insensitively
(preserving caller order) and capped at 25 — as a 422 refusal, not a silent trim,
because quietly dropping recipients is the same silent-success failure the
empty-list 422 exists to prevent.

**5. The test stole the runner's STORAGE_DIR (Minor).** `run_tests.py` assigns
`STORAGE_DIR=./_storage_{test}` and sweeps exactly that path; the test overwrote
it, so its 15 MiB blob landed somewhere the runner does not own. That is what the
suite footer's "dir(s) this runner does not own" counts, and the stray directory
was sitting on disk at 61 MB. Now `setdefault`.

Every fix is mutation-checked. Restoring the pre-fix code fails with: build
outside the try -> AssertionError on the per-recipient result map; size-after-read
-> "materialised <key>" from a patched storage.get, which proves the object was
pulled in; no cap -> 26 recipients accepted; no dedup -> a@ and A@ both served;
bare starttls() -> "called with no context — that context does NOT verify",
asserted through a fake SMTP that captures what is actually passed rather than by
reading the source.

* Second review round on #435: the port fix is the root cause my first fix missed

Three new findings on the fix commit. Two were real defects, one is a design
question answered rather than obeyed.

**A mistyped SMTP port escaped the no-raise boundary (Major) — and this is the
SAME defect class the previous commit fixed, one line above the guard.** That fix
moved `build_message` inside the try and left `int(AEC_SMTP_PORT)` outside it.
Settings are stored as arbitrary strings (`settings_store.set_value(db, k,
str(v))`, no numeric validation), so a typo in the Settings form raised
ValueError straight through a function documented never to raise, aborting the
delivery loop before its audit row — exactly the failure the CR/LF fix was for.
Treating the instance instead of the class is what left it. The whole prologue is
now inside the boundary: this function returns a status for ANY input,
configuration included.

**A recipient could forge log lines (Minor, CWE-117).** Both exception handlers
logged `to` with `%s`, so CR/LF in an address writes literal newlines into the
stream and a recipient can append a plausible-looking record of its own. Now
`%r`, which escapes them — the value is still reported, never as its own line.
This one was introduced by my previous commit, not found in old code.

**Cleartext SMTP auth: warned, not refused — deliberately.** The finding asks to
reject `send_email`/`smtp_test` outright when `AEC_SMTP_TLS=0`. That is a
documented deployment choice for a self-hosted product relaying through localhost
or a trusted internal MTA, where cleartext is not an exposure; hard-refusing
would break those installs to protect against a risk they do not have. What is
not defensible is doing it silently, so a credential sent without TLS now logs a
warning naming the setting and the remedy. The password is never logged, and the
test asserts that.

Mutation-checked: %s in place of %r puts the forged line back in the stream;
moving the port parse back outside the try loses the "error" status; removing the
warning loses the cleartext notice. The password assertion was rewritten after it
passed for the wrong reason — the fixture used "p" as the password and the
haystack was full of the letter p, so it now uses a distinctive value.

* Only committed capital owns anything — cap table and waterfall

`capital.cap_table` summed `commitment` across every investor whatever their
workflow state. A `prospect` carrying a $10M interest and $0 contributed took
50% of a $10M cap table and halved a real LP from 60% to 30%. It did not stop at
display: `distwaterfall` allocates `share = lp_total * (commitment / lp_commit)`
off these rows, so the prospect drew **$1,818,181.82 of a $2M distribution**
while the committed LP got $181,818.18.

**The obvious filter is wrong on its own, which is why this took a guard.**
`investor` declares `initial: prospect` and every record is stamped with it at
creation, so on a project where nobody ran the `commit` transition EVERY investor
is a prospect and filtering empties the cap table. The roadmap records this was
implemented once and made `test_distwaterfall` return 0.0 instead of $2,000,000.

`workflow_in_use` separates two readings of the same value: **a default state is
not a signal.** Until some investor has moved off the stamped initial state,
`prospect` means "nobody used the workflow" and everyone counts, exactly as
before. Once one has, `prospect` means "not committed" and the state is evidence.

Of the three options the roadmap put to the owner, this is (c). (b) — keying on
`contributed > 0` — was rejected as a domain error: in an uncalled fund an LP
with a signed commitment and no contribution yet is normal, and that rule would
zero out real LPs who simply have not been called. (a) — changing the initial
state — needs a data migration and rewires the default entry path.

Prospect rows are never dropped: they stay visible at 0%, their money reported as
`pipeline_commitment`, and they no longer sort above real owners, because rank in
a cap table reads as ownership. `by_class` follows the same denominator or the
two halves of one table contradict. The decision rides on each row as
`counts_toward_ownership` rather than being re-derived by each of seven consumers.
`exited` is evidence the workflow was used, but is not current ownership.

Mutation-checked, and one mutation earned its keep: removing the filter restores
30%/50%; dropping the `workflow_in_use` guard reproduces the recorded failure
(`test_distwaterfall` -> 0.0); and making `distwaterfall` ignore the flag was
initially NOT caught, because `test_distwaterfall`'s fixture has no prospect. That
gap is now covered through the real API, and the mutation fails with the
$1.8M-to-the-prospect split above.

* SCALE-SEAM (101) — design-phase predicted performance, client.ts 642 -> 603

Six methods out. Five to a new `apps/web/src/api/designPerformance.ts` (energy,
energyModel, energyExportUrl, carbonComplianceReport, projectCarbon) and
benchmarkCosts to cost.ts.

**The seam was drawn by earlier slices, not this one.** operations.ts's own
header records why projectCarbon did not go there — "EMBODIED carbon ... a
design-phase estimate. The GHG figures in esgSummary come from metered utility
data. Same molecule, opposite ends of the asset life" — models.ts records the
parallel call for /energy, and operations.ts does hold /energy/actual. Prediction
versus measurement, committed to twice independently. These five are the
prediction side of an axis this codebase already chose.

Not named environmental.ts on purpose: that names the TOPIC both halves share,
which is exactly what would re-blur the seam operations.ts drew. What separates
them is not subject matter but whether the number is forecast or observed.

**A planned benchmarks.ts was abandoned before any code was written.** Grepping
every /benchmarks caller showed two already live elsewhere: cost.ts holds
unitRates (/benchmarks/unit-rates) and schedule.ts holds benchmarksPullPlanning
(/benchmarks/pull-planning). So the repo had already decided that prefix
distributes by what each method ANSWERS, and a benchmarks.ts would have been
route-prefix grouping contradicting two live placements. benchmarkCosts went to
cost.ts instead, beside unitRates — the same question at a different granularity,
same low/p25/median/p75/high shape. benchmarkResponseRates and
spaceUtilBenchmarks STAYED: no existing mixin owns their question, and inventing
a home for two methods on a guess is what produced this file's UNFILED banner.

Two gates earned their keep. DOC-STRAND caught the extraction stranding
unitRates' doc comment above the inserted block — reunited, not deleted. And the
size ratchet reported 603 where `wc -l` said 602, which is the off-by-one its own
message warns about; the pin took the gate's number.
