2026-10-26 +- Catalog capability ID: `bugbot-analysis-and-autofix` +- Last verified: not applicable +- Owners: Copilot maintainers +- Scope: Preserve complete sanitized review conversation comments within the existing bounded context while retaining truthful completeness reporting and existing safety gates. +- Related issues/PRs: [Issue #724](https://github.com/vypdev/copilot/issues/724); [PR #719](https://github.com/vypdev/copilot/pull/719) +- Required review gates: product UX, architecture, testing, documentation, security/operations +- Open decisions blocking readiness: none + +> Prospective companion specification. It adds a focused conversation-fragment contract to the existing Bugbot capability. It does not replace or repeat its owning specifications. + +## 1. Executive summary + +Bugbot currently treats a logical review comment that exceeds the 4,000-character item limit as truncated. That can make overall review context partial even when diff analysis completed. The proposed change fragments the complete normalized and sanitized comment into bounded prompt fragments, wraps each fragment using existing untrusted-content framing, and reconstructs each selected logical comment exactly. Fragmentation does not create extra comments or increase any source, item, or total context limit. + +The recommended behavior is generic lossless packing for selected comments, including both generated User-account reports and ordinary human comments. No new report verification, producer allowlist, login-based trust, or heading-based trust is introduced. If a comment or other source cannot be fully retained within existing limits, coverage remains honestly partial. Full diff analysis and review-context completeness remain separately visible. + +```text +Fetch bounded sources -> normalize and sanitize each logical comment -> select up to 50 -> fragment and safely frame -> pack within 24,000 characters -> report source completeness and diff completeness independently +``` + +## 2. Problem, current behavior, and evidence + +### 2.1 Problem + +A reviewer or operator can see a partial review and a blocked lifecycle despite all diff-analysis partitions completing, because an oversized conversation item was truncated. This obscures which input is incomplete and can make a complete code analysis look incomplete. The correction must preserve the original evidence and provenance, retain genuine human discussion when it fits the established total budget, and avoid treating user-controlled report content or identity claims as trusted instructions. + +### 2.2 Current behavior + +1. The repository fetches and selects bounded review-conversation sources, retaining source identity and existing provider limits. +2. `bugbot_review_context.ts` normalizes NFKC, CRLF, and outer whitespace, then excludes existing provider-classified automated authors and configured Copilot-bot authors. +3. Remaining entries are limited to `MAX_CONVERSATION_ITEM_LENGTH=4000`; an oversized item is truncated. +4. `load_bugbot_context_use_case.ts` derives human-conversation partial status from omitted or truncated logical comment counts. `summarizeBugbotCoverage` combines source completeness. +5. On PR #719, the Codecov comment is attributed by GitHub as account type User and is 5,959 characters. The reported run completed 9/9 partitions with zero candidate or published findings, while conversation status was partial, `truncatedItems=1`, and `limitReached=true`. + +Steps 1–4 describe the supplied repository evidence. The issue report and telemetry are the concrete incident evidence; the proposed behavior is not current behavior. + +### 2.3 Evidence + +- Code/workflow/documentation references: `src/application/usecases/steps/commit/bugbot/bugbot_review_context.ts`; `src/application/usecases/steps/commit/bugbot/load_bugbot_context_use_case.ts`; `src/domain/bugbot/context.ts`; `src/domain/security/untrusted_content.ts`; `src/application/policies/bugbot_diff_partition_policy.ts`; `src/application/policies/bugbot_review_presentation_policy.ts`; `src/data/repository/issue/bugbot_issue_comment_query_repository.ts`; `src/application/usecases/steps/commit/bugbot/bugbot_context_request.ts`. +- Incidents or concrete examples: [Issue #724](https://github.com/vypdev/copilot/issues/724), [PR #719](https://github.com/vypdev/copilot/pull/719), and [the generated Codecov comment](https://github.com/vypdev/copilot/pull/719#issuecomment-6412438827). Reported telemetry: 9/9 partitions completed; open=0; verification-required=0; one truncated conversation item; review outcome partial. +- External primary sources: GitHub’s issue, pull request, comment, and Action run linked above. +- Unknowns: The historical reason for the 4,000-character item cap is not established by supplied evidence. This proposal preserves that per-fragment cap and all existing total/provider limits. + +### 2.4 Retrospective classification (as-built baselines only) + +Not applicable: this is a prospective companion and does not reconstruct an implemented baseline. Current behavior and verified facts are recorded in 2.2 and 2.3. + +## 3.

Neither completeness fact implies the other. + +GitHub owns source identity and original comment content. The application owns normalized/sanitized prompt copies, selection, packing, and truthful coverage counts. All comment body text is untrusted data, including generated reports, headings, markers, usernames, and delimiter-like text. + +## 4. Goals + +| Requirement | Behavior | +|---|---| +| LCC-1 | Retain the complete normalized and sanitized payload of each selected logical comment when it fits the existing section and source limits, using fragments no longer than 4,000 UTF-16 code units. | +| LCC-2 | Preserve normalization and security framing, exact ordered reconstruction, and source provenance; never split a valid surrogate pair or independently normalize fragments. | +| LCC-3 | Keep fixed conversation caps, source/provider limits, selection order, and logical-comment accounting unchanged; make omitted or malformed input truthfully partial. | +| LCC-4 | Keep provider-classified automated-author and configured Copilot-bot exclusions unchanged; introduce no new trusted-producer classification or identity/heading/marker trust. | +| LCC-5 | Report diff-analysis completeness independently from conversation/source completeness, preserving existing incomplete-coverage and guarded-approval behavior. | +| LCC-6 | Add executable policy, integration, security, and UX regressions; update the catalog and user/operator documentation in the same implementation change. | + +### 4.1 Goals + +1. Meet LCC-1 and LCC-2: eliminate avoidable per-comment truncation while keeping untrusted content safe and reconstructable. +2. Meet LCC-3 and LCC-5: preserve truthful counts and independent completeness signals under exhaustion or incomplete inputs. +3. Meet LCC-4 and LCC-6: retain existing trust and approval boundaries and make the behavior reviewable through tests and documentation. + +### 4.2 Non-goals + +1. Verify generated reports, introduce producer allowlists, or trust authors based on configurable logins, headings, or markers. +2. Increase the 24,000-character conversation section cap, 50-comment cap, provider/page limits, or the 4,000-character fragment limit. +3. Edit, delete, ignore, or replace GitHub source comments, or project a status-only substitute for a report. +4. Change diff partitioning, findings, protected-path policy, human-approval requirements, or extension-branch behavior. + +### 4.3 Fixed product/safety invariants + +1. All GitHub comment content remains untrusted, regardless of author account type or apparent automation. +2. A complete diff result cannot make incomplete conversation input complete, resolve missing evidence, or authorize guarded approval. +3. A complete comment reconstructed from fragments counts once and has no truncation record. Omitted or incompletely retained source content remains partial. + +## 5. Current versus proposed product journey + +| Stage | Current | Proposed | User/operator effect | +|---|---|---|---| +| Fetch and select | Bounded sources, existing provider and selection rules | Unchanged | Same comments and provenance are eligible | +| Normalize and frame | Normalize and sanitize, then truncate oversized remaining entries | Normalize and sanitize once, then fragment and frame each selected entry | Complete sanitized comments fit where the total budget permits | +| Pack | Truncation can count as incomplete | Pack complete logical comments and their wrappers within the same 24,000-character section cap | No per-item truncation solely due to the 4,000-unit fragment limit | +| Summarize | Any truncation or omission contributes to partial context | Fully reconstructed comments count once; actual omissions and unsafe malformed input remain partial | Honest source coverage without conflating completed diff analysis | +| Present | Partial result may obscure that diff partitions completed | Show diff and conversation completeness independently, with incomplete-coverage details | Reviewer can see what completed and what needs inspection | + +```mermaid +flowchart LR + A[Bounded source records] --> B[Normalize and sanitize once] + B --> C[Select logical comments] + C --> D[Unicode-safe fragments and untrusted framing] + D --> E{Within fixed section budget?} + E -->|yes| F[Reconstruct complete selected comments] + E -->|no or unsafe input| G[Record truthful omission or partial status] + F --> H[Independent diff and conversation coverage] + G --> H + H --> I[Review check and incomplete-coverage detail] +``` + +Text equivalent: bounded source records -> normalize and sanitize -> select comments -> fragment and pack under fixed limits -> record complete or partial source coverage -> present that independently from diff completeness. + +## 6. Functional behavior and state model + +### 6.1 Happy path + +1. The existing repository adapter fetches source records under current provider/page limits and preserves source IDs, author metadata, and source category. +2. The application applies current source selection and native automated-author filtering. No new identity or content-based trust rule is added. +3. The review-context builder normalizes and sanitizes each selected body once using existing behavior, then produces ordered fragments of at most 4,000 UTF-16 code units. +4. Fragment boundaries move backward when necessary to keep a valid surrogate pair together. Concatenating payload fragments reconstructs the sanitized logical comment exactly. +5. Existing untrusted-content framing wraps fragment payloads so delimiter-like input remains data. The complete rendered section, including wrappers, separators, and omission notice, remains at most 24,000 characters. +6. The loader counts selected/fetched/retained/omitted/truncated logical comments once each and sets conversation completeness from actual omissions or incomplete source retention. +7. Presentation reports diff and conversation status independently and retains existing guarded-approval behavior. + +### 6.2 Alternative paths + +- If the total section or 50-logical-comment limit is reached, preserve bounded source-category and aggregate omission counts; do not invent IDs or raw text for omitted comments. +- Fully reconstructed comments have `truncatedItems=0`. For affected retained comments, keep existing bounded IDs (`issue:` or `review:`, at most 160 characters each). Existing presentation displays at most 50 source IDs. +- If source content is omitted or only partially retained, report partial context and `limitReached` truthfully. Never claim clean or complete, resolve missing evidence, or authorize approval. +- If malformed or unpaired surrogate input cannot be safely represented, fail safely before claiming complete review. Do not silently discard content or fabricate replacement evidence. +- A valid surrogate pair at a proposed boundary is retained intact by moving the boundary; that adjustment is not truncation. + +### 6.3 State machine + +| State | Entered when | User-visible meaning | Allowed next states | Recovery/owner | +|---|---|---|---|---| +| Complete conversation | Selected logical comments reconstruct fully within limits | Conversation source is complete for retained scope | Review complete or diff-partial | Application coverage summary | +| Partial conversation | Any applicable source is omitted, truncated, or unsafe | Review context is incomplete; inspect listed coverage | Retry on a later run or remain partial | Loader and presentation | +| Diff partial | A required diff partition is incomplete | Code analysis is incomplete independently of conversation | Retry or remain partial | Existing partition completion policy | +| Review complete | Required diff and applicable context are complete | Review result is complete for the run | New run on new revision | Existing workflow lifecycle | + +Duplicate or out-of-order events continue to follow existing operation and revision handling. Fragment packing is a deterministic per-run representation; source records are never mutated. Cancellation and retry do not change an already emitted run’s packing facts. + +## 7. User-facing configuration + +No new user-facing configuration is introduced. + +| Input | Type | Recommended default | Allowed values/range | Scope/persistence | +|---|---|---|---|---| +| Conversation section cap | Existing fixed internal bound | 24,000 characters, including wrappers, separators, and omission notice | Fixed; not configurable by this change | Per analysis run | +| Retained logical comments | Existing fixed internal bound | At most 50 | Fixed; not configurable by this change | Per analysis run | +| Fragment length | Internal representation bound | At most 4,000 UTF-16 code units per fragment | 1–4,000, with safe boundary adjustment | Per analysis run; fragments are not persisted | + +Validation rejects unsafe fragment boundaries and malformed surrogate input from a complete result. Existing source/page/provider limits and current normalization/security policies remain authoritative. No precedence, migration, or alternative configuration is applicable because no configuration surface changes. The limits, author filtering, and approval gates are intentionally not configurable by this proposal. + +## 8.

Per-run context and telemetry carry logical counts and existing bounded IDs. +- Concurrency/idempotency strategy: deterministic per-run packing over immutable fetched records; no comment writes or new cross-run state. +- Trusted and untrusted inputs: provider metadata establishes source facts only. Comment bodies, author names, headings, markers, and embedded instructions are untrusted. Existing configured Copilot-bot exclusion remains unchanged. +- Provider error mapping: existing adapter/provider errors retain current behavior. Unsafe malformed text must not be converted into a complete result. + +### 8.3 Executable architecture constraints + +The pure packing policy must not import provider, SDK, filesystem, or workflow modules. Application code must depend on semantic source contracts, not provider DTOs. Add or extend an architecture test that rejects forbidden dependency directions and verifies the packing policy is composed through the existing loader. Contract tests must assert fragment reconstruction, cap accounting, and logical-comment counts from structured outputs rather than matching prose. + +## 9.

+``` + +Required state variants retain existing localized messages and presentation policy: + +- **Pending/no action:** “Review is running. No action is required while analysis is in progress.” Show completed partition progress and the run link. +- **Action required:** “Review context is partial. Inspect Incomplete coverage before treating this review as complete.” Show independent diff and conversation states. +- **Blocked or failed before irreversible effects:** “Review could not complete.

Failure, recovery, and cleanup + +| Failure/partial state | User impact | Retained facts | Automatic retry | Required action | Cleanup | +|---|---|---|---|---|---| +| Total rendered-section cap reached | Conversation is partial | Fetched/retained/omitted logical counts, source category, `limitReached` | Existing bounded retry behavior only | Inspect incomplete coverage or rerun after source changes | No source edits; discard per-run prompt representation normally | +| 50-comment limit reached | Some comments are omitted | Aggregate omitted count and source category; no fabricated IDs or raw text | No special retry | Inspect coverage details | No persistent fragment data | +| Malformed/unpaired surrogate input | Complete review cannot be claimed | Safe bounded source identity and failure/partial state | Existing workflow policy | Inspect source and rerun when corrected | Do not rewrite GitHub source | +| Existing provider failure or incomplete diff partition | Review remains partial independently of conversation | Existing provider/partition evidence and correlation | Existing retry policy | Follow current Action run guidance | Existing cleanup policy | + +Errors follow impact -> cause -> action -> retained state. A completed diff analysis remains reported as completed if only conversation retention is incomplete. + +## 11. Security, permissions, and privacy + +1. Preserve current least-privilege GitHub permissions and read-only source behavior; this change adds no write permission. +2. Treat all comment content as untrusted. Use existing `createUntrustedContent`, control-character removal, and safe/verbatim rendering rules. Literal terminators and delimiters in source text must remain data. +3. Do not log or persist raw comment bodies or fragment payloads. Keep existing bounded source IDs, counts, and sanitized diagnostics. +4. Do not infer trust from account login, account type, heading, marker, or claimed workflow provenance. Existing provider-classified automated-author and configured Copilot-bot exclusions remain as-is. +5. Malformed Unicode must not be silently replaced or dropped before a complete result is claimed. Fragmentation must not split a valid surrogate pair. + +## 12. Observability and operational UX + +- User-facing state: report `diff` and `human-conversation` completeness separately with existing localized coverage and partial-result presentation. +- Job Summary/operator evidence: retain fetched, retained, omitted, and truncated logical-comment counts; `limitReached`; bounded affected retained source IDs; and completed partition counts. A reconstructed comment has no truncation count. +- Logs, metrics, and correlation: use existing run correlation and bounded telemetry. Fragments are internal representation and are not counted as source comments. +- Pending external dependency versus workflow failure: preserve existing provider pending/failure distinctions; packing does not mask provider errors. +- Rate-limit/retry behavior: unchanged provider limits and retries. +- Noise/comment budget: no new comment per fragment and no increase in notifications. + +## 13. Compatibility, migration, rollout, and rollback + +- Existing in-flight operations/data: no persisted representation changes; an in-flight run uses its existing immutable fetched records and current code version. +- Schema/configuration migration: none; no public setting or durable schema is introduced. +- Deprecated behavior and compatibility window: per-comment truncation caused solely by the fragment limit is removed when the complete comment fits the section budget. True omissions remain partial. +- Rollout stages/feature flag if needed: no new flag is required; ship with the Action implementation after tests and documentation are updated. +- Rollback and irreversible effects: reverting restores prior per-item truncation behavior. GitHub source records and already published findings are not changed by packing. + +## 14. Testing strategy + +The minimum budget is 13 new distinct executable cases. Existing selection and diff-partition inventories remain unchanged and are referenced through `specs/bugbot-context-selection-and-budgeting.md` and `specs/bugbot-analysis-publication-and-autofix.md`; they are not recounted here. Every inventory row is one case in one exact budget area. New pure packing policy branches require 100% branch coverage; all changed lines require 100% coverage.

Given a selected 5,959-character Codecov comment attributed to a User account, when the sanitized comment fits the existing total section budget, then all payload content is represented by ordered fragments of at most 4,000 UTF-16 code units and reconstructs exactly, without classifying it as trusted automation. +2. Given a genuine human comment under the same conditions, when packing runs, then it receives the same complete retention behavior and remains untrusted conversation input. +3. Given a comment from a real provider-classified Bot, when existing filtering runs, then current automated-author exclusion behavior is unchanged; no new classification rule is inferred from its body. +4. Given an unknown User comment with a spoofed report heading or marker, when packing runs, then the heading or marker grants no trust and the body remains safely framed as untrusted data. +5. Given literal framing terminator text in a comment, when fragments are rendered, then it remains data and concatenated payloads equal the complete sanitized comment. +6. Given a valid surrogate pair at a 4,000-unit boundary, when fragments are formed, then the boundary moves to preserve the pair and exact reconstruction; given an unpaired surrogate, then the system cannot claim complete context. +7. Given a selected comment fully reconstructed from fragments, when coverage is summarized, then it counts once with `truncatedItems=0`. +8. Given total-section or 50-comment exhaustion, when coverage is summarized, then omitted and truncated logical counts, source category, `limitReached`, and bounded retained IDs are truthful; omitted comments receive no fabricated IDs or raw text. +9. Given mixed human and automation-filtered source records, when context is loaded, then provenance and logical counts remain correct and fragment count does not inflate comment count. +10. Given complete diff analysis but genuinely incomplete conversation input, when the check is rendered, then diff is shown complete, conversation is shown partial, the reviewer is directed to Incomplete coverage, and approval remains guarded. +11. Given incomplete diff or analysis input but complete conversation packing, when the review is summarized, then overall review remains partial because diff completeness is independently incomplete. +12. Given the partial result on a narrow screen, when reviewed without color or emoji, then state, completed work, next action, and links remain understandable. +13. Given implementation completion, when specification and documentation validation run, then the companion and catalog evidence are discoverable and all new cases map to requirements. + +## 17.
