Fixes #850

Twin: synonymdev/bitkit-android#1662
Refs: synonymdev/ldk-node#120

This PR updates LDK Node from 0.7.0-rc.76 to 0.7.0-rc.77, so incoming Lightning payments can use the whole channel instead of 10% of it.

Description

• Updates LDK Node to 0.7.0-rc.77 (release), which accepts incoming payments up to the full channel value on nodes that cannot announce channels, as Bitkit's node. Before, a single payment above 10% of the channel failed with no route.
• 0.7.0-rc.77 is 0.7.0-rc.76 plus fix: let unannounced channels take full-size payments ldk-node#120; no API changes.

Out of Scope

• Existing channels: the limit is set when a channel opens, so channels opened before this update keep the 10% limit until they are closed and reopened.

Design

N/A — no UI changes.

Preview

N/A — no user-visible UI change.

QA Notes

Setup

Regtest or staging with an LSP channel opened after installing this build.

Journeys

• J1: new receive-above-ten-percent-of-channel.xml — on a channel opened by this build, a single Lightning payment above 10% of the channel arrives

Manual Tests

• 2. Upgrade from a build on 0.7.0-rc.76 with an existing wallet and channels → the node starts, channels reconnect, balances match — upgrade path not in Capabilities

Automated Checks

• ran xcodebuild -resolvePackageDependencies — resolves ldk-node at 0.7.0-rc.77; Package.resolved pins the release tag's commit f05161ed

Evidence

• The fix itself was verified in fix: let unannounced channels take full-size payments ldk-node#120: its integration test fails without the change (a payment above 10% of the channel value is not routable) and passes with it.

Gaps

• J1 and manual test 2 not run on a device yet.
• Manual test 1 is retired: J1 covers it, since the LSP node pays from the journey harness.

Models used

• Planning/scoping: claude-opus-5-5 (reasoning: Not exposed)
• Implementation: claude-opus-5-5 (reasoning: Not exposed)
• Review: Not performed

No findings. Moves LDK Node from 0.7.0-rc.76 to 0.7.0-rc.77 so incoming Lightning payments can use the whole channel on new channels. Reviewed 4997c7c, full tier (dependency pin). Reasoned from the code and CI: iOS does not build on this reviewer's Linux host.

What I checked

Read in full: the 4 changed files; git grep rc.76 at the head finds no remaining pin.
Pin: exactVersion 0.7.0-rc.77 in the project matches Package.resolved, whose revision f05161e is the commit the v0.7.0-rc.77 tag in synonymdev/ldk-node points to (that tag's Package.swift checksum matches its published xcframework asset).
Upstream delta: rc.77 is rc.76 plus synonymdev/ldk-node#120 only, which touched no bindings, so no Swift call site here can break.
CI: SwiftFormat and validate green; Run Tests and build-local were still running when I read them.

Merge confidence: 4/5, a dependency bump not built here, with Run Tests still pending and the rc.76 upgrade path (manual test 2) not run yet.

Confidence Score: 5/5

[Medium impact] The PR appears safe to merge, with no actionable issues found.

Summary

Updates ldk-node from 0.7.0-rc.76 to 0.7.0-rc.77 to allow larger incoming Lightning payments on newly opened channels.

• New Bitkit channels can receive payments up to their full value.

Pushed 012fdf8: adds the journey receive-above-ten-percent-of-channel.xml (J1), which receives a payment above 10% of a newly opened channel, paid from the LSP node. Manual test 1 is retired in its favour; the QA notes are updated.

[pwltr]

Approved. The exact rc.77 requirement and resolved commit match the published LDK Node release, and Bitkit’s node configuration activates the increased inbound limit. No API changes or blocking integration findings. Existing channels retain their negotiated limit; newly opened channels get the change.

Build, unit tests, integration tests, formatting and E2E are green. Approval is based on source/dependency review and CI; device journey J1 and upgrade check 2 remain unverified as documented in the QA notes.

Put on 3.1.0: merged to master for the next release.
