Its +`context` must equal `manifest.binding`: compare the repository, run ID/attempt, +policy and actual collector checkout revision with trusted runtime values, retaining +the collector's original memory head. Transport the manifest in a separately named, +immutable, same-run artifact uploaded by the collector. Neither the artifact name +nor its contents may come from the model or an agent-writable file. + +## One model-visible proposal route + +For repository-pinned **GH AW v0.76.1**, use one custom job named +`publish-regression-triage`, with one **required string** input `proposals`. +Its acknowledgement must be: + +> Proposal received for validation; publication is not confirmed. + +Pass the entire raw JSON text from `GH_AW_AGENT_OUTPUT` as `output` to retain +duplicate-key detection.

Citations can address current title/body, human comments, linked +issue/PR text, reviews and review comments. Deterministic provenance checks are +**not semantic proof**: the classifier must consider human corrections, intended +changes, unsupported setups and automation failures, not the word "regression". + +The model cannot choose labels, repository, branch/path, permissions, operations, +comment bodies or state deltas. Do not enable independent built-in label/comment +safe outputs. Missing output is an error and does not commit discovery progress. +A valid empty batch commits the complete trusted discovery delta. + +## Durable state and recovery + +Only `memory/regression-triage:state.json` is written. Reads pin the file to the +authoritative branch head; absence is confirmed separately from forbidden, +corrupt or failed reads. Initialization creates that literal branch at the +repository API's default-branch head. State commits use GraphQL +`createCommitOnBranch`, `expectedHeadOid`, one literal file addition and a fixed +message. There is no shell push, tree upload, unsigned fallback, or agent-writable +automatic repo-memory ledger. + +The publisher first CAS-saves the **whole** trusted scan/queue/read-age delta and +prepared publication intents. Operation IDs bind repository, issue, policy and +human fingerprint. A bounded `discoveryReceipt` binds the most recent manifest +and accepted batch; retries cannot change the accepted decisions. A second CAS +claims each external attempt before a fresh complete snapshot immediately adjacent +to the issue write. Only the literal `Regression` label can be added, never removed. +`Needs-Triage`, human label applications/removals and stored human corrections +are preserved. Negative/uncertain classifications never remove labels. + +Each record retains the analyzed fingerprint, classification, compact reported +citations, policy, missing fact, latest actual outcome, latest human label decision, +correction excerpt, clarification status/receipt and any unfinished intent. +Compatible unknown fields and fair-read age survive schema-1 policy migration. +Unsupported schemas and malformed known fields fail instead of resetting history. +The serialized store is bounded to 1 MiB and fails explicitly when +full; it never silently evicts human history or receipts. + +`published` means the effect was observed after the request; `noop` means no issue +mutation was needed. `stale`, `retryable` and `unknown` keep work pending and must be +surfaced by the caller, as must thrown errors. A post-write correction/closure +records a partial stale outcome without undoing the effect. Request errors are +unknown outcomes until a real label/receipt is observed, not success-shaped +fallbacks. Prepared intents can resume; claimed attempts without an observable +result are retained without blind retransmission. A known-unsent failed recheck +returns its claim to prepared state. + +Clarifications are fixed, short, AI-disclosed questions with an issue-level marker +independent of policy/fingerprint. Recovery accepts a live marker only from the +configured **ID + login + API Bot type**, never a human copying it. Durable receipts +also prevent repeats after comment deletion. If the ledger is confirmed missing, +the publisher conservatively persists `clarificationHistoryUnknown`; absence +cannot prove that a previous question was never posted. It still records the +missing fact and can add Regression, but does not start new questions with +ambiguous history. Restoring the trusted ledger restores its history. + +On CAS mismatch the adapter reloads after a failed mutation and throws retryable +`CAS_CONFLICT`; the publisher never replays a stale whole-manifest queue or cursor. +There are no automatic CAS retry loops. Recollect from the latest state on a later +run. GitHub has no transaction spanning issue state, labels, comments and memory: +adjacent rechecks and durable claims reduce races, not provide absolute exactly-once +guarantees. Do not configure transport-level retries for comment creation. + +## Staged execution and workflow wiring + +Trusted `staged: true` **or** `GH_AW_SAFE_OUTPUTS_STAGED=true` forces a local sink. +The same validation, complete rechecks, record construction and recovery execute, +but neither `store.commit`, branch creation nor issue mutations run. Receipts are +`would-add-label`, `would-comment`, and `would-save-memory`. Returned state can seed +an in-memory store for staged restart tests; it must never be committed as live +publication history. + +The independently triggered workflow is not implemented here. When wiring it: +import unchanged `shared/model-defaults.md`, compile with v0.76.1, serialize all +triggers in one concurrency group with `cancel-in-progress: false`, and give only +the trusted custom publication job issue/content write permissions. In that +version custom safe jobs cannot depend directly on `pre_activation`/`activation`; +use the trusted immutable artifact transport instead. Preserve the existing +project-labeling and Repo Assist workflows and their separate memory. + +## Local verification + +```powershell +node --test .github\scripts\regression-triage\core.test.cjs .github\scripts\regression-triage\publish.test.cjs +node --test (Get-ChildItem .github\scripts\regression-triage -Recurse -Filter *.test.cjs).FullName +node --check .github\scripts\regression-triage\core.cjs +node --check .github\scripts\regression-triage\github.cjs +node --check .github\scripts\regression-triage\publish.cjs +git --no-pager diff --check +``` + +Tests use the frozen classification corpus, shared collector simulation, fake +REST/GraphQL and an interleaved CAS store.

Keep ambiguous histories pending, migrate legacy terminal noops, and reconcile recovered creation timestamps without replaying unresolved comment attempts. Add existing-ledger controls and missing branch/file, boundary, migration and receipt recovery coverage. Both prescribed Node suites pass all 396 tests; syntax, formatting and diff checks pass. The clean Release solution build passes with zero warnings or errors. Full solution tests have reported failures; results are retained in the session logs.

It adds the existing +`Regression` label to open `Needs-Triage` reports supporting previously working +behavior becoming broken. This means **reported regression awaiting reproduction**, +not independently verified behavior or a bisected cause. It neither requires +`Bug` nor removes `Needs-Triage` or any human label. + +## Operation and safety + +Issue opened/edited/reopened/labeled/transferred and human comment +created/edited/deleted events supply issue-number hints, never authoritative +state. Unknown contributors are readable (`roles: all`, `min-integrity: none`). +PR payloads, bot event senders/comments and labels other than `Needs-Triage` are +filtered before model activation. Scheduled collection still reads real reports +opened by bots and their human discussion. + +Hourly reconciliation covers automation-generated labels that do not trigger +another workflow, missed events and replacement of pending concurrency runs. +For example, an opened event can precede `add_to_project.yml` applying +`Needs-Triage`; the next sweeps discover it without a label event. There is no +creation-date cutoff, search-cap enumeration or issue-number cursor. +All triggers share `regression-triage` concurrency with cancellation disabled. + +The collector uses read-only credentials and immutable `github.workflow_sha` +helper code. Only the default-branch workflow/ref is accepted, including manual +dispatch. The two dispatch inputs are an optional positive safe issue number and +a boolean `staged` (default true), not arbitrary instructions. The compiler also +injects internal `aw_context`; this adapter accepts it only when empty. + +The model reads a separate input artifact containing exact current human and +directly linked issue/PR text, source identities, fingerprints and a small prior +record excerpt. It cannot execute samples, access attachments, edit files, use +shell/CLI/web-fetch tools, or write GitHub data. Its GitHub MCP surface is limited +to issue/PR reads. Untrusted text cannot authorize extra tools or operations. +GH AW v0.76.1 still emits an edit grant for `edit: false`; a trusted +`pre-agent-steps` launcher prepends Copilot's overriding write/shell/URL +denials, excludes delegation and disables custom instructions. The generated harness invokes that +launcher after the checksum-verified CLI installation; the shared model stays +unchanged. The detector has the same restrictions: its verdict goes to stdout, +which the trusted framework records, so it needs no model-side file writes. +One custom safe output accepts a strict bounded proposal batch; receipt is not +publication. It must cover every selected report and cite each report itself, +not just a linked comparison. Missing-data/tool, no-op and failure-as-issue routes +are disabled. + +The publisher runs only after successful agent/threat detection. Its read/write +token is confined to that trusted job. It resolves the immutable collector artifact +by this repository/run/attempt/policy/code-SHA prefix, rejects missing or ambiguous +artifacts, checks service run metadata, downloads by ID, and verifies the content +hash in its name. The model cannot upload/delete/replace this artifact. No +agent-workspace file supplies publication authority or memory deltas. + +## Bounds, memory and recovery + +Production limits are five classifications, ten issue-list page requests and ten +snapshot reads per run. Each snapshot bounds comment/timeline reads to ten requests +each, five direct links and five requests per PR review endpoint. Discussion +enumerations must agree across two passes; moving pages or incomplete dependencies +are not complete evidence. Input is limited to 48 KiB per selected entry and +192 KiB per batch; oversized entries remain pending, never silently truncated. +The manifest is bounded to 4 MiB. The collection step has a ten-minute deadline; +the agent and publication have fifteen-minute deadlines. Trusted Node watchdogs +enforce collection/publication deadlines because v0.76.1 discards custom step +timeouts. An interrupted publisher leaves its persisted intent for recovery. + +An update-time scan with fifteen-minute overlap and an independent labeled-backlog +sweep retain page boundaries and continuations. Durable per-issue read ages and +reserved historical capacity prevent repeatedly reading the same first reports. +The staged suite drains eleven stable reports at these production limits. + +Authoritative memory is schema 1 `state.json` on **`memory/regression-triage`**: +scan continuations, pending queue, fingerprints, policy, cited evidence, missing +facts, actual results, human decisions, clarification receipts and pending intents. +It is not agent-writable repo-memory or an Actions cache. +`createCommitOnBranch(expectedHeadOid)` persists whole discovery deltas together +with work/intents using CAS. It is **not** a transaction across GitHub API calls. +See the [helper contract](../scripts/regression-triage/README.md) for state details. + +Even empty selections submit `results: []` so the publisher can preserve discovery. +Missing output or failed agent/detection leaves old memory for retry. Incomplete +scans/reads are summarized; the publisher retains pending work and fails the job +visibly after saving legitimate progress. A CAS conflict requires recollection, +not replay over a newer head. Failed memory reads never become empty memory. + +Immediately before each mutation the publisher rechecks open/Needs-Triage state, +complete human/linked fingerprints and human label decisions. Corrections invalidate +stale proposals; human rejection/removal is not silently reversed. Policy-version +changes reanalyze without resetting human decisions or clarification receipts. +When changing classification semantics, bump `POLICY_VERSION` and the workflow's +example/artifact-name version together, freeze expectations and rerun evaluation. +At most one fixed-template question is asked; unresolved/missing historical +receipts suppress potentially duplicate questions. Never delete memory to retry. + +`staged: true` **or** `GH_AW_SAFE_OUTPUTS_STAGED=true` suppresses all issue writes, +branch creation and remote memory commits; model fields cannot disable either. +The custom job exposes the latter through the repository variable of the same name. +The job summary shows would-label/comment/save receipts. Staging does not advance +remote memory; local integration explicitly reloads the returned simulated state. + +No supported bisector workflow exists in this inventory. A separate bisector +can discover `Regression` through reconciliation, not solely bot-generated label +events. This workflow does not dispatch anything, especially not the regression +PR shepherd.

Do not +build, download or run samples, attachments or historical source. + +Classify as `regression` only when the report supports previously working behavior +becoming broken under a meaningful comparison. Explicit good/bad versions, a +linked causative change and precise observable differences are useful evidence. +The word "regression" is neither necessary nor sufficient evidence. A missing +known-good comparison is `uncertain`, not evidence of `not-regression`. + +Keep compiler, FSharp.Core, SDK, runtime, target framework, Debug/Release +configuration, producer and consumer versions distinct. Cite what was held +constant and what changed. Do not manufacture SDK or compiler versions from +each other. Runtime-only failures can be regressions in generated compiler output. +Consuming an old producer binary with a new compiler is not the same experiment +as recompiling both sides; assess the actual producer/consumer comparison. + +Feature requests, documented intended behavior changes, unsupported configurations, +recurring automation failures and unrelated CI incidents are not automatically +product regressions. `not-regression` requires affirmative evidence; otherwise use +`uncertain` and state the missing fact. + +Prefer current explicit human corrections over contradicted original claims, +including corrections found only in the supplied linked discussion. Cite a +rejecting correction using the optional `correction` field when applicable. +Preserve human-applied Regression. Do not silently reverse a human removal or +rejection: if the supplied current discussion/decision rejects the regression +claim, do not recommend it again. The publisher independently enforces these +decisions. Label removal alone vetoes publication, but does not disprove a reported +before/after comparison; classify the evidence without overruling the label veto. +Cite rejecting human text, not a label/timeline entry. Prior records are a read-only +excerpt, not permission to change state. +Existing labels are not evidence of a before/after comparison. Classification and +label preservation are separate: a human-applied Regression stays in place even +when the evidence is uncertain or affirmatively describes a never-existing feature. +Never choose `regression` merely to preserve that label. + +A positive result means **reported regression awaiting reproduction**, never +independent reproduction, verified product behavior or a bisected cause. +Do not start bisection or any other workflow. + +For uncertainty state a specific missing fact. If a useful clarification has not +already been asked, choose at most one of `known-good`, `affected-component`, +`comparable-configuration`, `producer-consumer`; otherwise use null. The publisher +owns the fixed question text and lifetime receipt; never compose a public comment. +Policy/fingerprint changes do not authorize repeated questions. +When the baseline is missing or retracted, explicitly identify the missing +**earlier known-good comparison**, with the relevant source, configuration or +unchanged producer binary. A possibly successful future version is not that fact. + +Citations must cover the current symptom, expected behavior, before/after +comparison and stated held-constant controls. Include relevant facts from both +the report and its linked sources, including an explicitly absent baseline. +Every result must include evidence from the selected report itself: cite its +current symptom or request from its body, title or human discussion, even when a +linked PR supplies a strong comparison. Linked citations supplement that root +citation; they never replace it. Check this explicitly before submitting. +When a claim is corrected, cite both the original claim and the correcting +evidence; the correction governs the conclusion. Do not cite only the final +failure or only the correction and discard the comparison's context. +Keep related before/after statements and their qualifiers together in one +self-contained quotation, not disconnected fragments. Prefer the full contiguous +paragraph when it fits the 1000-character bound; otherwise use complete sentences +that retain the relationship, including whether settings were identical. + +## Strict output + +Submit exactly one `publish_regression_triage` safe-output call with the string +argument `proposals`, containing this JSON shape: + +```json +{"schemaVersion":1,"policyVersion":"reported-regression-v1","results":[{"number":42,"fingerprint":"COPY_SELECTED_FINGERPRINT","classification":"regression","evidence":[{"sourceId":"COPY_EXACT_SOURCE_ID","url":"COPY_EXACT_SOURCE_URL","quote":"EXACT_SUBSTRING","dimension":"compiler"}],"missingFact":null,"clarification":null}]} +``` + +Use the supplied policyVersion.

A batch is at most 65536 UTF-8 bytes. +`classification` is exactly `regression`, `not-regression` or `uncertain`. +`evidence` contains at most 12 exact source citations; positives need at least one. +Use the snapshot's `titleSourceId`, `bodySourceId`, or human comment `sourceId` +and corresponding canonical `url`, including linked sources. Quotes must be +nonempty exact substrings of the cited text and at most 1000 characters; source +IDs at most 200 and URLs at most 500 characters. Cite the actual comparison and +current corrections, not invented facts. Optional evidence `dimension` is one of +`compiler`, `sdk`, `fsharpCore`, `runtime`, `targetFramework`, `configuration`, +`producer`, `consumer`. +For every quoted paragraph, emit a separate citation for each relevant dimension +it establishes, not just its dominant topic. A paragraph about compiler versions +and build configuration needs both tags. A missing earlier-working baseline for +a known compiler/configuration is relevant to both; a never-supported option +combination needs `configuration` evidence even when a compiler rejects it. Compiler +identity or changed/unchanged compiler facts use `compiler`, even when the compiler +is a consumer; producer/consumer binary-version relationships additionally need +their respective role citations. Observed execution results use `runtime`; +compilation success/failure and type-checking diagnostics use `compiler` when +the comparison independently identifies the compiler, even when the bug is only +observable at runtime. +Debug/Release contrasts use `configuration`. SDK and FSharp.Core version facts +need their own tags, not a single compiler/package tag for a whole paragraph. +Audit outcome coverage separately from control coverage: a citation saying which +compiler changed does not replace a citation saying whether compilation succeeded. +For a runtime-only generated-output failure, include a `compiler` citation for +the reported successful compilation on both sides as well as a `runtime` citation +for the execution contrast. A mixed paragraph may need citations under both tags; +including a compilation fact inside a runtime-tagged quote alone is insufficient. +For producer/consumer experiments, cite the producer binary's compatibility fact +under `producer` and the consumer's success/failure (including rebuilding both +sides) under `consumer`; a passage establishing both roles can be cited for each. +Component attribution takes precedence over phase and multi-dimension tagging. +If compiler identities/versions are unknown in an SDK-only comparison, use no +`compiler` citations at all: even "builds with the old SDK, fails with the new SDK" +is `sdk` evidence, not independently established compiler evidence. Cite the known +SDK facts and omit a dimension on unknown details. + +`missingFact` is a nonempty string of at most 1000 characters for `uncertain`, +and null otherwise. `clarification` is null or, only for uncertainty, one fixed +selector above. Optional `correction` is an exact `{sourceId,url,quote}` citation +to a human rejection, only for non-positive results.
