Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The AI dispatch changes can produce provider request failures and allow credential resolution to outlive request timeouts or cancellation, potentially leaving requests hung. Ticker limit handling and test cleanup also need follow-up, so the PR is not ready to merge safely until the transport issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@packages/plugins/ai/doc/init.md`:
- Around line 66-70: Update the AiConfig configuration reference to document the
dynamic context fields timeZone, locale, calendar, and sphere, including their
supported supplier-function behavior, matching the API advertised in the Dynamic
Provider Credentials & Context Suppliers section.
In `@packages/plugins/ai/doc/security.md`:
- Around line 126-128: Update the key supplier to validate the result of
tenantStore.getStore() before accessing openaiApiKey; throw a tenant-context
error when no tenant context exists, and return the tenant-specific key
otherwise so the AsyncEvaluable<string> contract is preserved.
In `@packages/plugins/ai/src/core/support.ts`:
- Around line 68-74: Update the fallback selection around rawLoc so resLoc and
cfgLoc are accepted only when defined and, for arrays, non-empty; preserve the
existing priority order and en-US final fallback while ensuring an empty
resolved locale array allows the configured locale to be selected.
In `@packages/plugins/batch/package.json`:
- Line 3: Synchronize release metadata across all four sites: in
packages/plugins/batch/package.json lines 3-3, keep version 1.0.2 and update
packages/plugins/batch/CHANGELOG.md lines 5-8 so its top entry is 1.0.2 if it
documents that release; likewise, keep version 1.0.4 in
packages/plugins/finance/package.json lines 3-3 and rename or replace the top
entry in packages/plugins/finance/CHANGELOG.md lines 3-6 to 1.0.4 when it
documents that package release.
Apply the same fix in `@packages/plugins/snap/CHANGELOG.md` around lines 8 - 12:
The snap changelog lacks an entry for the manifest version.
In `@packages/plugins/ticker/doc/index.md`:
- Around line 253-255: Update the pulse() entry in the ticker documentation to
state that it returns the emitted pulse Tempo, not the next internal Tempo after
advancing state.
- Around line 84-87: Update the Tempo.ticker example using until to include a
deterministic seed before the until value, ensuring the seeded start time
precedes the configured deadline and the example remains executable regardless
of the current date.
In `@packages/plugins/ticker/package.json`:
- Line 27: Update the prepublishOnly script in package.json to perform the
main-branch check through a cross-platform Node.js script or command instead of
POSIX [ ... ] syntax, while preserving the existing failure message, exit
behavior, and npm run build execution.
In `@packages/plugins/ticker/README.md`:
- Around line 29-31: Update the TickerPlugin initialization example to register
it through the extends option rather than plugins, using Tempo.init with extends
containing TickerPlugin or Tempo.extend before initialization so Tempo.ticker is
attached.
In `@packages/plugins/ticker/src/index.ts`:
- Around line 279-311: Update `#scheduleNext` and/or `#delayMs` to prevent immediate
zero-delay rearming when `#current` is past-dated, particularly for backward or
negative-interval tickers. Apply a minimum positive delay or stop the catch-up
chain once the schedule is not advancing toward the present, while preserving
normal future-schedule timing and existing limit/until termination behavior.
In `@packages/plugins/ticker/test/ticker_cold_start.test.ts`:
- Around line 12-16: Replace the ineffective count-based idle assertion in the
ticker cold-start test with an assertion on t.info.ticks, verifying it remains
zero after the 250 ms wait before the listener is added; keep the existing
listener behavior unchanged.
In `@packages/tempo/bin/resolve-types.ts`:
- Around line 40-42: Remove the flat declaration copy using destFlat and retain
only the nested declaration copy via destNested in the resolve-types flow.
Ensure each nested index.js module continues writing its matching declaration
under its domain directory without creating or overwriting a root
lib/index.d.ts.
In `@packages/tempo/plan/v4-architecture-modernization-plan.md`:
- Line 23: Replace each machine-local file:///home/michael/Project/magma/...
reference in the architecture modernization plan with a repository-relative link
or stable repository URL, preserving the existing targets and link text across
all five references.
