fix(booking-ui): the consultee can finally answer a reschedule proposal - #1177

The #1169 train's wave-1 PRs carried their own documentation; the late
ones (#1174, #1177, #1178, #1179, #1180) shipped without changelog rows.
Adds 21 rows to the August 2026 table, each verified against the PR diff
rather than the PR description, plus a note in 01-architecture recording
that the client auto-allocator is gone and the grid now polls.

* docs(collaborators): rewrite all seven files against the merged Collaborator model

The collaborators folder was the worst-drift band in the repo: it still
documented the deleted WebinarCollaborator/ClassCollaborator models and
their per-type role enums (merged into one Collaborator model by #784),
a permissions JSON override (replaced by four typed booleans in #768, of
which only canSeeAttendees is enforced today), a nonexistent
lib/collaborators/permissions.ts module and checkWebinarPermission
function, and a float revenueSharePercentage column (revenueShareBps Int
since #772 B5). All seven files are rewritten from the current code:
service.ts, availability.ts (the AE-2 enforced co-host guard), the
collaboration routes, and the settlement path in earnings-service.ts
(pool-based split with floors per #778 §C-2, org settlement per #773,
verified Stream revocation per #1125).

Part of #1169.

* docs(payments): re-verify every file:line citation in the funding-seam doc

The prose was correct but the line references had drifted: the Payment
model is at prisma/schema.prisma:4136-4242 (doc said 3515-3563),
FundingSource at :1100 (said 901), and the fundingSource resolution at
checkout.ts:1986 (said 1907). The remaining refs in the doc had drifted
the same way (PaymentLeg, WalletTopUp, skipPayment, walletDebit, and the
refund.ts audit/clawback/Step-9 blocks); each new number was verified
against the current files before writing. Also cross-links the new
booking-side page for this rail.

Part of #1169.

* docs(booking): document the org-funded checkout rail

docs/booking/ documented the sponsored path nowhere. The new
17-org-funded-checkout.md covers, with verified file:line refs: the
shared checkout route with optional organizationId; the resolution chain
(canSponsor gate, overdue-invoice dunning suspension, ACTIVE membership,
DPDP consent, fundingSource from the org BillingAccount, INVOICE
credit-limit and verified-domain gates, ProgramAssignment resolution —
which fails closed rather than falling back to the learner's card — and
the ADR 18 allowlist/exclusivity gates inside the lock); the gateway
skip with synthetic org_* intents; the atomic conditional-updateMany
wallet debit; CLASS debiting N engagements at checkout while
SUBSCRIPTION debits lazily per allocation; and inline settlement with
the booking-journal posting, including what happens when the posting
fails after the booking has committed. The README quick-nav gains rows
for 15, 16 and the new 17.

* docs(prompts): index the corpus, fix the ledger drift, reconcile the seed cohorts, add two booking cases

Four changes to the prompts corpus. (1) A new prompts/README.md indexes
the 43 prompt files by directory and states how the enterprise-tests
tree relates to docs/enterprise/90-audits/03-verification-guide.md.
(2) shared-setup.md stops teaching the deleted three-ledger models:
FundingLedgerEntry and SettlementLedgerEntry (and WalletEntry) were
replaced by the LedgerAccount/LedgerTransaction/LedgerEntry double-entry
journal plus UsageLedgerEntry in #772 — rule 2, the glossary section,
the webhook-idempotency note and the schema table are all corrected.
(3) The two documented seed cohorts are reconciled: the founder@*.test /
TestPassword123! roster in shared-setup §2 never existed in the seeds
(and its table swapped the IIT/LearnPro shapes); the verification
guide's SeedPass123! roster matches prisma/seedFiles/, so §2 now defers
to it and each doc points at the other. (4) Two new case files in the
Agent-005 template style: 007 covers the reschedule-proposal response
loop (lands with train PR 3, #1162) and 008 covers maintenance-freeze
correctness — a freeze must not destroy a PENDING payment, and
freeze-then-cancel must not double-refund (lands with train PR 4,
#1163); both carry explicit coverage markers. New files are added with
-f, matching how the ignored-but-tracked corpus is versioned.

* docs(skills): add the booking-doctrine skill

Captures the booking subsystem's seven non-negotiable invariants for
future agents: CAS status transitions through lib/booking/transitions.ts
(the WHERE clause is the state machine); nothing is deleted (soft-cancel
via completionStatus and tombstones — never delete an appointment a
Payment points at, #1074); the two refund front doors and the three
intent rails (gateway pi_/cs_/order_/pay_, internal org_*, free_); the
one-lock-namespace rule under utils/appointmentlock.ts with the global
lock order; the prisma/sql sidecars applied via db:sidecars; explicit
org scoping with personal surfaces pinning organizationId null; and the
testing recipes (background dev server + mock data, never db push;
__tests__/booking-algorithm and __tests__/payments; chaos runbook).

Part of #1169.

* docs(misc): ADR 20 no-drill-in addendum + booking changelog entry for the refresh

ADR 20 gains a dated addendum stating plainly that the org "Everyone"
appointments table is metadata-only by design — the missing row link is
intent, not a gap — so the 2026-08-13 audit finding stops being
re-reported as a bug. The booking troubleshooting doc gains a 2026-08-14
changelog section for this documentation refresh (#1169, closing #1013).

* docs(skills): model-orchestration — the advisor/teacher/student tier split

Encodes the pattern that shipped the #1169 train and the session-budget
lesson that cost it four agent fleets: judgment on the advisor tier,
spec-following execution on the teacher tier, mechanical breadth on the
student tier, per-role effort levels, the commit-early limit clause, and
the resume-from-worktree recovery pattern. Placeholders left for team
defaults.

* docs(booking): changelog rows for the late train PRs

The #1169 train's wave-1 PRs carried their own documentation; the late
ones (#1174, #1177, #1178, #1179, #1180) shipped without changelog rows.
Adds 21 rows to the August 2026 table, each verified against the PR diff
rather than the PR description, plus a note in 01-architecture recording
that the client auto-allocator is gone and the grid now polls.

* docs: adversarial-review corrections — merged-reality alignment

Four corrections against merged dev, each verified before writing.

Rule 4 of the booking-doctrine skill listed `trial-slot-booking:` as a
live lock namespace. #1170 retired it entirely: trials now take the
shared `slot-booking:` atom keys, one key per 30-minute atom the booked
interval covers, floored to the half-hour grid. The rule also still
promised the consolidation as future work; it has landed.

`08-cancellation-flow.md` was untouched by this train despite the PR
claiming `Closes #1013`, and PRs 4 and 6 never picked it up either — the
file is byte-identical on dev. It still taught delete-on-cancel, no
authentication and no refunds, which are the three claims #1013 was
raised against. The walkthrough, every diagram, the record tables and
the error contract now match `cancel/route.ts`. The #1006 escalation for
partly-consumed subscriptions is gone: #1006 is closed and the linear
per-session proration replaced it, so the refundable base is
`floor(gross × sessionsRemaining / slotsTotal)` for subscriptions and
the policy tier applies to that base. The only surviving `MANUAL_REVIEW`
path is the credit-funded partial-window case (#1161).

The collaborators rewrite dropped a qualifier the pre-PR text had right:
`assertCollaboratorsAvailable()` is called from the webinar plan route
alone, so class-plan co-hosts have no availability guard. The over-claim
had spread to six files, all corrected.

`16-recurring-events-journey.md` still named the deleted
`ClassCollaborator` model; de-drifted to `Collaborator` with
`collaboratorType: CLASS` and `revenueShareBps` (#784, #772 B5).

The ~27 stale citations in `17-org-funded-checkout.md` and
`payments/05-b2c-b2b-funding-seam.md` are deliberately left alone —
they re-derive after this branch's final rebase.

Part of #1169. Closes #1013.
