A held reminder can come back on a day the agent picks, and shows on Today's reminders that morning #299

A draft held on the review page can now be given a "Bring back on" date, and it returns on its own that morning. I haven't tried it in a running preview.

What changed

• Hold: holdReminder (src/deals.ts) takes an optional backOn date. It must be a real date, today or later, and no more than 365 days out; anything else is refused as invalid and nothing is stored. With no date, hold behaves exactly as before.
• Doors: the review page has a date input next to Tomorrow, posted to /reminders/today/hold. The JSON API (back_on) and the MCP hold_reminder tool accept it too, and contract/openapi.json is re-emitted. The existing same-origin and permit checks apply unchanged, and contract.json is untouched.
• Storage: a new nullable reminder_hold.back_on column, added by an appended migration with the pin file updated. Existing held rows stay held with no date.
• Returning: the existing until column already drives when a held draft comes back, so before the date the draft stays out of the list, the count and /tick. From that day it is listed again with its edited words intact. A dated one is labelled "Back from hold" instead of "Held from <weekday>".
• Held drafts: the deal page shows "Returns <date> by <name>" for a dated hold.
• Finished screen: dated holds are counted separately as "N held until a day you chose.", so the existing "N held until tomorrow." count stays right. The flash after a dated hold reads "Held until <date>."
• README: a sentence under reminders. The "Bring back on" label is deliberately not bold, because the tour test checks bold names against pages.

Tests

• src/holddate.test.ts covers a dated hold hidden before its day and shown on it, undated unchanged, and past, too-far and garbage dates refused. It also covers anon refused, the migration keeping old rows, the finished-screen counts, and the web form with a foreign origin refused and a bad date returning 422.
• I edited the old-database test in src/migrations.test.ts: it lists migrations to skip and replay, so I added back_on to that list.
• The affected suites pass: hold, review, migrations, leaks, openapi, readme, design and settled.
• bun x tsc --noEmit printed only its help text, because the repo has no tsconfig.json. So there was no type check here.
• In one wider run, two tests in src/terminal.test.ts and src/tour.test.ts timed out at 5 s. I attributed that to load, not the change, but I didn't re-run them in isolation.
• There is no scripts/gate.ts. docs/VISION.md is absent, and the design lint script is scripts/lint-design.ts (it printed nothing, so I took it as clean).

Chose not to do

• No dated-hold edit or cancel beyond the existing release and re-hold. Holding again without a date clears the date and waits one day past the current hold.
• Nothing touching parties (#287) or amend (#290).

To try it: open /reminders/today, pick a date, press Tomorrow, then look at the deal page for "Returns …".

Closes #292

The preview deploy failed because my earlier push broke three tests, and those are fixed in the latest push (32f8f75). I re-ran the affected suites (tour, README, reach, speed, hold and review) and they pass. A full local bun test still had 3 failures: the README tour test, which I then fixed and re-ran green, and two that I didn't re-check after the fixes. Those two are the people speed budget and a timeout in the terminal reach test.

What broke and how I fixed it

• Reach migration test: it assumed the newest migration is the reach one, and my back_on migration is now newest. It now finds the reach migration by its text.
• Review page reach test: the page called dayOf(agent) for the new date input's minimum day, and that test renders the page with no agent. It now uses dayOf(agent ?? {}).
• README tour test: my "Bring back on" sentence sat inside tour step 6, which src/tour.ts mirrors word for word. I moved it into its own README section, "Holding a reminder for later".

Still failing: the speed budgets

• The "answers in under 50 ms" tests (people, review, clock) failed in the deploy log. They passed when I ran src/speed.test.ts after the fixes, but failed on the people route in the full local run.
• I checked src/speed.test.ts alone with my changes stashed and it printed no failure, so I couldn't tell whether the full-run failure comes from my change.
• The two timeouts in src/terminal.test.ts also failed in the deploy, and they timed out under load in my earlier runs.
• Treat the speed and terminal results as unconfirmed until the next deploy log.

One test was still failing in the preview deploy, and I've pushed a fix (2259919). src/terminal.test.ts now passes in full locally, 53 of 53. I haven't seen the new deploy log yet.

The failing test was "p and e set how a party likes to be reached…". It takes about 5.4 s on the base commit 3a44623, before any of my changes, and about 5.9 s on this branch. Bun's per-test timeout is 5 s, so the test was hovering at the limit and fails depending on machine load. It's a long run of scripted key presses against the shared sample book, and it isn't related to the hold-date work.

I gave that one test a 20 s timeout and left the test's checks alone. The test is still slow; I didn't investigate why or speed it up, so a person may want to look at that later.

In the terminal, h on a reminder now asks "Bring back on (YYYY-MM-DD, blank for tomorrow)" and passes the answer to holdReminder as backOn. src/terminal.test.ts passes in full (54 tests); I did not re-run the rest of the suite after this change, and did not run bun x tsc --noEmit (there is no tsconfig.json).

• Behaviour change: h used to hold at once, so existing terminal tests that pressed h on the reminders list now press Enter to accept the blank answer. The src/waive.test.ts press of h is on the dates view, not the reminders list, and is unchanged.
• New test: src/terminal.test.ts now has a test for the date prompt. A garbage date and a past date each hold nothing. A date two days out sets until and back_on to that day and says "Held until <date>". A blank answer holds until tomorrow with no stored date, as before. Anon is still refused by the existing guest check.
• Docs: the terminal's header comment and footer hint, docs/TECHNICAL.md and the README now describe the date prompt.
• Slow-test timeouts: I raised the timeout to 20 s on a second slow terminal test, "the deal view says which other closing the same day is less than two hours away". It sits near Bun's 5 s limit and timed out in the earlier deploy too. The test body is unchanged.
