Of ~75 candidates across 13 subsystems, only 13 survive as actionable (1 adopt-now, 12 adapt) — roughly 47 are already-have (pythinker implements them in its own kimi-derived soul idiom, frequently MORE robustly than the reference, e.g. abort tool_result pairing, single-flight dedup, the typed wire union, fail-closed PreToolUse blocks, the lazy skill index, and the shimmer/theme TUI), and the rest are stub-only/rewrite-defer/anti-pattern. Most of the reference's load-bearing subsystems (real model calls, compaction, stop-hook executor, token budget, skills discovery, memory injection, MCP/LSP, the agent loop trampoline, the permission gate interior) are explicit '# TODO(port:' no-op skeletons, so their value is design-reference only. The genuinely adoptable items are small, additive, and safe: one read-only prompt-dump command, plus narrow hardening around resource-bounding (parallel fan-out cap, USD spend ceiling), permission safety (dangerous-dotfile re-confirm then accept-edits tier), prompt cache-stability (separate-reminder context), hook steering (additionalContext injection), file-edit safety (read-before-write cache), and a couple of telemetry/observability caveats. The single largest item (max-output-token escalation) is blocked on a pythinker-core precondition (core captures no finish_reason, so truncation is silently accepted today) and is therefore last and partly cross-package. + +**Gap stats:** adopt-now: 1, adapt: 12, already-have: 47, stub-only: 4, rewrite-defer: 5, anti-pattern: 8 + +## Recommended waves + +### Wave 1: Low-risk additive hardening (no behavior change to existing happy paths) _(est. risk: low)_ + +- **Items:** `dump-system-prompt-entrypoint`, `shell-timeout-literals-not-interpolated`, `per-memory-freshness-disclaimer`, `bounded-parallel-fanout-cap`, `max-budget-usd-loop-stop` +- **Rationale:** All single-file or near-single-file, OFF-by-default or observational, no tool-semantics change.

Reference WIRING is NOT portable: reference memory injection is stubbed (memdir/memdir.py:2 'Phase 1: no memory section') and the only live call site is FileReadTool output (file_read_tool.py:290-294), not an injected block — adopt the mtime->note TECHNIQUE only; the literal string at memory_age.py:35-38 is reference-only. +- **Current evidence:** LIVE injection path is RecallInjectionProvider (registered app.py:381-385) rendering via memory/recall.py:build_recall_block (:129-169); existing caveat (recall.py:141-143) is authority/actionability NOT freshness; durable snapshot header (project_memory.py:460-465) calls memory 'durable facts' with no staleness note; recency only affects RANKING (retriever.py:84-85), never a model-facing note; grep for freshness/stale/point-in-time/verify-against found no per-block caveat +- **Reference liveness:** live +- **Adoption sketch:** Add a tiny pure helper (memory/freshness.py with freshness_note(mtime_epoch) returning '' for <=1 day old else a generic pythinker-worded caveat — DO NOT copy the reference literal string). CRITICAL CORRECTION to the naive sketch: durable-tier blocks (MEMORY.md/USER.md/JOURNAL.md) are injected with created_at_epoch=now (recall.py:254-263), so keying the caveat off per-block created_at_epoch would NEVER fire for the file:line citations that motivate it. Drive the durable-tier staleness note off the FILE mtime already computed by RecallInjectionProvider._memory_files_mtime() (recall.py:293-309); reserve per-block created_at_epoch for the scratch tier (recall.py:241).

nothing live to port) + +- **fallback-model-retry-on-overload** — In-loop fallback-model retry on provider overload: verify REFUTED liveness: the handler at loop.py:628-674 is real but its trigger FallbackTriggeredError has ZERO raise sites (defined once at with_retry.py:90), and the overload-classification-and-raise logic lives in the deferred multi-attempt loop (with_retry.py docstring: 'model-fallback decision is infra-bound, TODO(port: P3)'). The handler can never execute. Gap is genuinely missing in pythinker (no in-loop overload->fallback concept; _step retries the same model via tenacity) but there is no live behavior to port — design only. +- **cost-state-restore-on-resume** — Restore accumulated cost/usage when resuming a session: verify REFUTED liveness (AND-gate): the durable cross-resume continuity unit is exactly the reference's TODO(port:P3) stub — cost_tracker.py:209-215 _project_config is in-memory only ('round trips WITHIN a process'), save writes to a dict not disk, so nothing survives a real process restart. Genuinely missing in pythinker (context.py persists only token_count; cost/usage are fresh per run) but no reference code to port — extend-the-_usage-journal design is reference-able, low priority. +- **token-budget-continuation-nudge** — Per-turn token-budget continuation nudge + diminishing-returns early stop + completion telemetry: Double-stubbed in the reference (feature('TOKEN_BUDGET')=False AND get_turn_output_tokens hardwired to return 0). Pythinker's structural intent is already served by bounded _run_goal_continuations (goal.max_continuations), the one-shot intent-nudge, and the consecutive-failure 'stuck' backstop. Adopting the token-budget algorithm needs new per-turn output-token telemetry pythinker does not track at turn granularity — a new feature, not a port. (Covers diminishing-returns-early-stop and budget-completion-telemetry siblings.) +- **static-dynamic-cache-boundary-marker** — Static/dynamic prompt-cache-scope boundary sentinel: Only meaningful with cross-organization/global prompt-cache scopes (the reference's should_use_global_cache_scope, a vendor-specific beta). Pythinker is multi-provider and does not segment prompt caching by org scope, so the marker would be inert. Pythinker already gets the equivalent win for free: dynamic content lives in user-role messages after the byte-stable system.md. Revisit only if a provider-level global cache scope is introduced. +- **render-tool-hooks** — Per-tool UI render hooks (tool-use message, result, activity description): Reference hooks are explicit P6 no-op stubs returning None. Pythinker has its own render layer (ToolReturnValue.display/BriefDisplayBlock, wire ToolExecutionStarted events, extract_key_argument feeding TUI/ACP) — nothing live to port. + +## Rewrite-defer (would require a loop swap / large structural rewrite — out of scope) + +- **graduated-stall-ramp** — Stall severity as a continuous color ramp toward an error hue: verify confirmed=false (the task gate drops unconfirmed candidates out of adapt; the stray final_verdict:adapt in the data is inconsistent and not honored). The reference interpolation math is live and the blend primitives already exist and drive the shimmer ramp, but the current ActivitySnapshot.stalled field is DEAD scaffolding never set by any producer (both construction sites rely on the default False; git log -S confirms it was born unused and the consumer branch motion.py:301-302 is unreachable). There is no stall-detection infra at all. Adopting the ramp therefore requires BUILDING a stall-detection signal first (a new feature), not porting a pattern — out of scope for a polish pass. +- **unified-can-use-tool-seam** — Single can_use_tool decision seam returning {allow|deny|ask}: Even the scout's '80/20' sliver only relocates the deny-or-pass profile gate; Approval.request remains a separate seam with a different return type (ApprovalResult vs ToolError|None). Folding both into one decision object is a structural rewrite of the approval subsystem, already tracked as blueprint P2b. The reference seam interior is itself hollow (auto-mode classifier/acceptEdits/bypass fast-paths + ask-handler all TODO(port) stubbed), so it does not even prove the payoff. +- **declarative-allow-deny-rule-config** — User-configurable source-precedence allow/deny/ask rule strings: The session-allow sub-capability is already-have (signature-keyed session approval, approval.py:535/623). What remains — user-authored persistent rule files with user/project/local/cli/session source precedence, a rule-string parser, a wildcard matcher, persistence, and a config UI — is a new subsystem, exactly the broad-infrastructure-for-edge-cases the AGENTS.md simplicity rules forbid building speculatively. The shell classifier the rules would gate is itself a P3 stub in the reference. +- **structured-output-retry-cap** — Structured-output mode with a bounded retry counter via tool-call counting: Pythinker has no headless json_schema/output-contract mode, so there is nothing to bound — adding a StructuredOutput tool + schema-validated result mode is a feature, not a gap-fill. If a `--output-schema` headless mode is ever added, the retry-cap-via-tool-call-counting technique is the right pattern to adopt then, implemented over pythinker's Message.tool_calls. +- **user-configurable-keybindings** — User-configurable keybinding system (closed action/context vocabulary + JSON config + resolver): A user-facing feature (config schema, parser, context-aware resolver, public config key + docs/tests per compatibility rules), not theme/spinner polish. The reference default_bindings carry a TODO(port) stub. If user-rebindable keys are ever prioritized, scope it as its own task touching config.py + a new keybindings module + keyboard.py dispatch. + +## Anti-patterns in the reference (do NOT import) + +- **heterogeneous-attr-or-key-message-switch** — Stringly-typed attr-or-key discriminator dispatch over mixed dict/dataclass messages: The reference's _mtype/_msubtype/_attr switch exists only because it reconstructed message types from an absent src/types/message.ts and mixes dicts with dataclasses. Pythinker already has a typed wire protocol + typed TurnOutcome dataclass; adopting the stringly-typed discriminator would be a regression. +- **to-auto-classifier-input** — Per-tool compact rendering feeding an LLM-driven auto-mode security classifier: No consumer exists: pythinker auto-approval is a deterministic allowlist + token classifier, not an LLM security-classifier transcript. The hook only pays off after building that whole classifier subsystem — out of scope for the tool base contract. +- **swarm-teammate-coordinator-machinery** — Multi-agent swarm / in-process teammate / coordinator-mode spawn paths and external build gating: Reverse-engineered multi-agent/remote features, almost entirely stubbed (NotImplementedError / dead external-build-gated and feature-flag-gated branches carrying leaked external-internal symbol names). Importing any of it adds a large speculative spawn surface with no live behavior and would surface external product names. Pythinker's fan-out is already served by launching multiple foreground/background subagents. +- **agent-source-precedence-merge** — Agent-definition source-precedence merge (project overrides builtin): Refuted: pythinker already registers project markdown agents with NEW names; the only behavior the merge changes is the collision case, where today builtin wins by deliberate skip-and-warn. agents/default/agent.yaml:40-72 shows ALL ~12 builtins are core role agents, so there is no 'non-protected builtin' to safely override — adopting it would let a project silently CLOBBER a fixed core role agent. Keep the skip-and-warn inverse design. +- **module-global-mutable-state-budget** — Module-global mutable accumulators for turn/token accounting: Would break pythinker's multi-instance/ContextVar invariants. Pythinker already carries this state on session-scoped objects surfaced via the typed wire StatusUpdate; the reference's free-function globals (get_turn_output_tokens hardwired to 0) are a stubbed anti-pattern. +- **cwd-memoized-style-cache** — Memoize the resolved output-style set keyed on cwd: A cwd-keyed global cache is justified only by per-build re-resolution across multiple on-disk sources; pythinker resolves the prompt once at agent-load, so it adds a global mutable plus a stale-style invalidation bug for zero benefit. +- **verbatim-proprietary-prompt-text** — Byte-for-byte verbatim model-facing description strings + external build/user-type gates: The reference prompt files are reverse-engineered proprietary text with external-product build gates; copying the literal wording or the external-gate/internal-user-type/fidelity-verifier machinery is forbidden. Pythinker's own original .md descriptions are the correct compliant approach. +- **stringly-typed-hook-event-bus** — Stringly-typed event/regex-matcher hook dispatch: The matcher is inherent to the user-facing hook config contract (a public compatibility surface) and is already defensively handled (invalid regex fails closed-to-non-match with a warning). Do not 'improve' it into a typed matcher DSL — that breaks the documented config.toml hook schema for zero correctness gain. diff --git a/tests/auth/test_kimi_auth.py b/tests/auth/test_kimi_auth.py
