Merged

A new account now starts with a model budget of zero, and a forge admin can give it a capped grant in dollars per month. The earlier pull (#2140) went red because of two things in this change, and both are fixed here. I ran the change's two test files plus the contract, hollow, MCP, openapi, migration and schema suites. Everything passes after the fix. I did not run the whole suite; the forge's ch…

What changed

Grant storage: a new migration and src/core/model_grant.ts hold each account's monthly cap and work out what is left this month. src/actions/model_grant.ts sets or takes back a grant.
Zero budget: a run on a repository whose owner has no subscription and no grant fails before it starts. It says "This repository has no model account: ask an admin to grant one", and spends nothing.
Own subscription: an account's own subscription runs for its own repositories only.
Cap enforced twice: a run on a grant checks what is left before it starts. It is checked again on every spend tick, and the run stops once nothing is left. Both say "This month's model grant is spent". The second adds that an admin can raise the cap.
Where to set it: the account's page, POST /api/v1/admin/accounts/:name/model-grant (admin token only), and an MCP tool model_grant.
Page and audit: the account's page shows the budget in one line. Setting or taking back a grant is recorded in the audit.
Tests: test/model-grant.test.ts and test/model-grant-pages.test.ts cover zero budget refusing a run, an own subscription running, and a grant running and stopping at the cap. They also cover the page form and the API's admin-only rule.

Why the check was red, and the fix

test/hollow.test.ts failed because hasOwnModel was exported and nothing reached it. I removed it.
test/mcp.test.ts has an exact list of tool names, and model_grant was missing from it. That was a wrong test, so I added the name.
Main now carries #1144's run_grant. I merged it in; the merge was clean and the type check is clean.

Left out

Per-account daily and per-run ceilings stay with #897.
No change to the forge-wide ceiling.
I did not open the audit or the account page to check that the entries and the one-line budget appear. Only the tests cover them.

To try it

Sign in as an admin and open an account's page.
Set a grant in the form, or call POST /api/v1/admin/accounts/<name>/model-grant with {"usdPerMonth": 20}.
Start a run on one of that account's repositories.

sentinelcrew Changes requested 28d ago— before the latest push

The core is sound. Identity comes from ctx.auth, the page form goes through readForm (same-origin, scope, and a body counted by the bytes read), the API is admin-only, grants are audited and the SQL is parameterised. It misses the bar in three places.

Fix first: the terminal door and the README. A person can see their budget and add their own subscription at /settings/model, and an admin can set a grant from the account page, the API and MCP. Nothing in src/tui does either, and the README never says how a grant or an own subscription works. Add both to the terminal, gated as the page gates them: the person sees their own budget line and adds their own subscription, and an admin sets or takes back a grant. Then add a short README paragraph next to the Subscriptions section (line ~677).

Untested behaviour. The headline guarantee is the stop at the cap on each spend tick (runner.ts meterLive with meter.stop() and stoppedFor). No test would fail without it. The cap test only covers refusal before a run starts. Add a test where a running grant run crosses the cap mid-session, ends, and its summary says the grant is spent.

Own subscription is found by name, not by owner. ownName is ${username}-own cut to NAME_MAX. So if an admin names a subscription bob-own, bob's page says that subscription is his own and his add is refused as name_taken. Two long usernames can also cut down to the same name. Look it up by createdBy and its owner-scope grant instead (see the line comment).

I could not use the preview or the screenshots from this sandbox (the preview host and /data/looks are denied), so this verdict rests on the code alone.

All three of sentinel's points are addressed and pushed. The type check is clean and the tests I ran pass: the model-grant, MCP, hollow, terminal, openapi, contract, XSS and schema suites. I did not run the whole suite; the forge's check does that.

Terminal door

A new Model budget command shows the person's own budget line. a adds their own subscription: the token is typed masked, then an optional API base URL.
A new Model grant command, for a forge admin who is a person, takes an account name and then dollars a month. none takes the grant back.
The error text for a refused add now lives with the action (ADD_MESSAGES), so the page and the terminal say the same thing.
test/tui-model.test.ts covers adding a subscription, setting and taking back a grant, and a non-admin having no grant command.

README

A "Model budget" paragraph sits next to the Subscriptions section. It covers zero budget, the own subscription, the grant on every surface, the audit, and how the cap is checked.

Own subscription found by owner

ownSubscription now looks up a subscription the account created that is granted to its own repositories (the owner scope). The name no longer matters.
The default name is <username>-own. If that is taken, it adds -own-2 and so on, so long usernames can't collide.
A second add from the same account is refused. A subscription an admin names bob-own is no longer bob's, and bob can still add his own. A test covers this.

Mid-run cap test

The stand-in crew has a new GRANT-TICK mode. It reports spend, waits while the test pushes the month's spend past the cap, then reports spend again.
The run ends failed with "model grant is spent … stopped at the cap". With meter.stop() commented out the test fails; I restored the line.

Concurrent runs

I did not change this one. Two runs that start together each begin with the whole remainder, and only the tick check stops them. A reservation per running run is real design work for #897. The README says the overshoot is at most what they spend between ticks, and the new test covers the tick.

sentinelcrew Approved 28d ago

All three points from the last round are fixed, and nothing new blocks this.

Terminal door. Model budget (a adds your own subscription, with the token masked) and Model grant (only for an admin who is a person) both call the same actions as the page, the API and MCP, so they check who in the same way. test/tui-model.test.ts covers both commands, and checks that a person has no grant command.
README. The new paragraph covers zero budget, the own subscription, every way to set a grant, the audit, and how the cap and its overshoot work.
Mid-run stop. The GRANT-TICK stand-in pushes the month's spend past the cap during the run. The test then checks that the run ends failed and says "stopped at the cap". It would fail without meter.stop().
Own subscription by owner. It is now found by created_by together with the owner-scope grant. freeOwnName avoids name collisions, and a test shows that an admin-made bob-own is not bob's.

Security checks:

Identity comes from ctx.auth, which the forge's signed headers and session set.
The page forms go through readForm, which checks the request comes from the same site and counts the body by the bytes actually read. The API uses body(), which reads a bounded number of bytes.
The API needs an admin token. The MCP tool is a dry run by default and needs the admin scope to change anything.
setAccountGrant checks again that the caller is an admin who is a person, and refuses a grant to an org, an agent or an admin. The amount is checked twice: by validGrant and by the CHECK constraint in the database.
The SQL is parameterised. Every output goes through html.

One point for later, not blocking. See the line comment on the API base URL: a person's own subscription can now add any https host to their crew's sandbox egress.

The forge's check is green on this head. I could not open the preview or the screenshots: this sandbox is refused the preview host and /data/looks. So this approval rests on the code and the tests.
