Issue being fixed or feature implemented

Reviewing agents are often triggered by missing "prerequisites" or "backport is not full but partial" false alarm if the feature is meant to be skipped intentionally.
There's example of alerts that I see on GitHub for backports:

#7646 (comment)

🔴 Blocking: Missing fee-bumper prerequisite chain for bitcoin#25344
Upstream merge 73966f7 adds an outputs option to bumpfee_helper, parses it through AddOutputs, forwards replacement outputs through feebumper::CreateRateBumpTransaction, updates feebumper.{cpp,h} and wallet/interfaces.cpp, and adds wallet_bumpfee.py coverage. This backport changes only the generic raw-transaction helpers and documentation because Dash lacks the fee-bumper implementation and bumpfee/psbtbumpfee RPC chain. Commit 0c8c405 and the PR title nevertheless advertise bitcoin#25344 as a full merge. Backport the applicable prerequisites and omitted behavior/tests, or explicitly mark and document bitcoin#25344 as partial.

#7684 (comment)

🔴 Blocking: Document the complete witness and replacement-test exclusions

The bitcoin#26631 commit is explicitly partial and mentions both missing Taproot descriptors and a witness/Taproot fixup; its omitted dust cases are P2WPKH, P2WSH, P2TR, and future witness versions 2 and 16. The separate bitcoin#26646 commit is still advertised as a full backport, but omits upstream additions to package_witness_swap_tests, the effective-fee assertions in rpc_packages.py's test_rbf, and the response-shape updates in p2p_segwit.py. Those sections exist before upstream bitcoin#26646 but are absent from Dash's base and head. Under the full-backport completeness requirement, absent prerequisite test sections need an explicit exclusion rather than silently disappearing. Mark bitcoin#26646 as partial and enumerate the intentionally excluded witness/replacement hunks in the backport metadata, or supply the missing coverage. This is a backport-scope blocker, not a demonstrated runtime failure or a request to introduce SegWit or RBF into Dash.

As well, it happens also with automated backports flow [dashcoreautoguix], that had been active in the past:
It attempted to do completely irrelevant backports, such as bitcoin#26107: [test] only run feature_rbf.py once - see DashCoreAutoGuix#74

What was done?

Added a list of features that meant to be always omitted for Dash Core and should not be considered as "missing" or "forgotten" or "required" by reviewing agents.

How Has This Been Tested?

Let's see how agents will do review on github.

Walkthrough

The change documents upstream features that Dash Core does not implement, including SegWit, replace-by-fee, feefilter, and Signet. It identifies Taproot-related features as temporarily absent. The BIP documentation removes entries for unsupported descriptor-wallet, wtxid-relay, and descriptor BIPs.

⚠️ DEGRADED — Final review — Phase 1 only (trivial change)

⚠️ DEGRADED review. The primary review models were unavailable (gpt-6-astra unavailable: All credentials for model gpt-6-astra are cooling down (last error: usage_limit_reached: The usage limit has been reache), so this review ran on stand-in models: gpt-5.6-lunamuse-spark-1.3-contributor, gpt-5.6-solmuse-spark-1.3-contributor, gpt-5.6-terramuse-spark-1.3-contributor, gpt-6-astramuse-spark-1.3-contributor. Both review phases and the independent verifiers still ran, but on weaker models, with Phase 1 capped at high effort. Treat the verdict as provisional; a full-strength re-review will run on the next push once the primary models are back.

Docs-only PR adds never-adopt guidance and prunes doc/bips.md. The pruning and new guidance are broadly consistent, but BIP 86 removal conflicts with the Taproot roadmap that explicitly names BIP 86 as a future candidate, and two grammar errors were introduced.

- [SUGGESTION] doc/bips.md:3: BIP 86 removal contradicts Taproot roadmap and BIP 386 retention
  This PR removes the BIP 86 entry while adding a preamble stating omitted BIPs are ones Dash "will never have". AGENTS.md and CLAUDE.md explicitly list "BIP 86 paths" as part of a possible future Taproot project to be treated as "temporarily absent", not permanently excluded. BIP 386 (tr() descriptors), also Taproot-related and unimplemented as a Dash feature, is retained at line 50. Either retain BIP 86 alongside BIP 386 or narrow the preamble so deferred Taproot BIPs are not mischaracterized as never-adopted.
- [NITPICK] doc/bips.md:3: Fix subject-verb agreement in omission note
  Line 3 says "BIPs that describes". The plural subject requires "describe". Fixes a grammar error introduced by this PR.

  Lines 218-219 say "treat them as temporary absent or incomplete". "Temporary" is an adjective; the adverb "temporarily" must modify "absent". Same fix is required in CLAUDE.md lines 216-219, which must stay in sync per the repo guide.

Re-review — Final review — Phase 1 only (trivial change)

The documentation-only changes introduce permanent feature-exclusion guidance and remove irrelevant BIP entries without changing runtime or consensus behavior. AGENTS.md and CLAUDE.md remain identical, all three prior findings are addressed at the exact head, and git diff --check passes. No actionable in-scope findings remain.
