Reviewed c373a35. No actionable bugs found in this planning-only amendment. Seeding Source from the resolved catalog handle is the right direction: it closes the initial own-path race while preserving lazy sibling resolution and the documented stitch lifecycle. Planned API impact is a breaking Source::new change; wire impact is none.
Unlike the concern in the existing review, exporter-side seeding can be safe: TS already carries the exact resolved broadcast into build_with. Retain that handle rather than resolving again.
Non-blocking test clarification for source-pin.md: explicitly exercise catalog A resolved, replacement B wins, then Source is constructed from A and makes its first track request. This distinguishes constructor seeding from the previous lazy-cache design.
Verification: inspected the complete two-file diff, Source/Binding, TS construction/follow logic, HLS Upstream, caller search, and current reviews. No tests or quest check run; implementation remains deferred.

When this quest lands, downstream Rust users must change every Source::new call, yet the plan limits documentation to Source and inline comments. The existing next-breaking-release section in doc/setup/upgrade.md already documents related Source and TS export migrations, so omitting this constructor change would leave the user-facing migration instructions incomplete; include an update to that existing paragraph rather than creating a new page.

Not applied here: the maintainer decided docs for this quest as "No, inline only", and adding a doc/setup/upgrade.md entry would amend that. The Unreleased section there does record comparable Rust breaks (Source::returned, ts::Export::resume), so I've raised it with the maintainer to decide.

The maintainer accepted this. Applied in d7064c8: the quest's Public API paragraph now adds a line for the Source::new break to the Unreleased section of doc/setup/upgrade.md, still with no new doc page.

Reviewed c91417b against the previously reviewed c373a35. No new actionable bugs found.
The added constructor-after-replacement test scenario addresses my earlier non-blocking suggestion. The exact-handle seeding and HLS self-reference conditions make the implementation boundary clearer. The direction remains sound.
The existing upgrade-guide discussion remains a maintainer documentation-scope decision; no duplicate finding here.
Verification: reviewed the changed plan and current discussion. The comparison contains one descendant commit with an unchanged base, not a rebase. No implementation changed; no tests or quest check run.

- Line 1: Qualify the source-pin plan title to state that an export’s later
requests remain on the broadcast only for its own path and sibling paths already
resolved by `Source`; update the summary in `README.md` to express the same
path-specific guarantee, allowing a sibling first referenced after replacement
to resolve the then-current broadcast.
- Around line 57-59: Clarify the plan’s treatment of the crate-private
Source::pinned helper: state whether the new broadcast argument to Source::new
replaces it. If the helper is removed, include updating the ts::Export call and
epoch-pin test to pass the resolved broadcast through Source::new.

Reviewed d7064c8 against c91417b. No new actionable bugs found.
The updated documentation requirement addresses the existing upgrade-guide finding at the planning level. Extending the existing Unreleased section is appropriate for the breaking constructor change. Handle-seeding design and planned regression coverage remain unchanged.
Verification: inspected the plan delta and current review discussion. One descendant commit, unchanged base, no runtime changes. No tests or quest check run; implementation and the actual upgrade-guide entry remain future work.

Implements the #5251 amendment to the source-pin quest. `Source::new` takes the catalog broadcast its caller resolved, which seeds its own-path handle, and `Source::broadcast()` returns it without awaiting. Every caller resolves first, so no first lookup through `Source` can land on a replacement. moq-hls's `Upstream` catalog hold is gone, since the source holds that broadcast itself, and `Broadcaster::new` no longer awaits or fails.
