P0: fix ChatGPT↔DevSpace caller continuity, live tool projection, and evidence-chain liveness

[James3014]

Problem

Governed DevSpace work is repeatedly stalling for reasons unrelated to the target feature. #236 exposed a recurring control-plane deadlock:

1. The live M5 DevSpace server can advertise git_commit and direct_candidate_execution_evidence while the active ChatGPT callable tool projection does not expose them.
2. Refreshing/reopening the controller surface can change caller identity, after which the same physical Core mutation session fails with CORE_MUTATION_ACTOR_MISMATCH.
3. There is no reliable same-actor tool-manifest refresh or explicit safe caller-rebind/continuation contract.
4. A second DevSpace namespace may be a different host/state root entirely (for example M4/jameschen vs M5/james), so it cannot safely substitute for the original session.
5. Evidence lifecycle semantics have also drifted from real execution lifecycle: successful workers settle as idle/completed, while direct evidence previously expected stopped/completed; mixed writer domains also could not durably narrow CLEAR domains while preserving UNKNOWN domains.
6. Provider qualification is being treated too globally even though host generation matters: HOME, PATH, Node version, provider binary/version, auth state, DevSpace build and state root can differ by Mac.

Fresh main at issue creation: 89828be

Why this is a design bug

The current workflow couples four independent concerns too tightly:

tool-schema freshness
+ caller identity continuity
+ Core mutation provenance
+ evidence producer lifecycle

This creates a deadlock pattern:

need refreshed tool surface
-> refresh/rebind changes caller identity
-> existing Core session becomes inaccessible
-> Candidate/evidence cannot continue under original provenance
-> controller must restart governed work or create recovery plumbing

Governance should remain fail-closed, but refreshing capabilities must not routinely destroy continuity of the exact governed effect.

Evidence from #236

• Wave-3 attempt-6 Candidate already exists: a873ddb.
• Worker replay is not required.
• Live M5 server catalog reported git_commit while one ChatGPT conversation had no callable git_commit method.
• Later continuation attempts hit CORE_MUTATION_ACTOR_MISMATCH on the same physical Core session.
• Another DevSpace namespace exposed git_commit but proved to be the M4/jameschen server/state root, so it could not legally continue M5 provenance.
• A two-file evidence-lifecycle repair reached 25/25 focused tests, typecheck PASS, build PASS and diff-check PASS, yet Candidate formation was blocked by caller/tool binding rather than code correctness.

Relevant #236 reconciliation markers:

• issue236-wave3-attempt6-evidence-lifecycle-blocker-20260924-v1
• issue236-wave3-lifecycle-repair-verified-host-schema-block-20260924-v1
• issue236-evidence-lifecycle-repair-verified-actor-rebind-blocker-20260924-v1

Required outcome

A. Same-actor capability refresh

Provide a supported way to refresh/rebind the live DevSpace tool manifest without silently changing Core actor identity. Expose at least server instance/build/source identity, client projection generation, caller identity and projection freshness.

B. Explicit continuation when caller identity must change

If same-actor refresh is impossible, provide a first-class handoff/rebind operation that binds old caller, new caller, exact workspace/session/effect identity, reconciles unresolved effects first, and preserves Candidate/evidence lineage.

C. Observable catalog convergence

The controller must be able to distinguish CURRENT, SERVER_AHEAD_OF_CLIENT, STALE_RECONNECT_REQUIRED and CALLER_REBIND_REQUIRED instead of seeing a live server tool that is simply undefined client-side.

D. Evidence lifecycle aligned to real execution

Preserve and verify the bounded fixes already identified: idle/completed is a valid successful direct-evidence lifecycle; independently CLEAR writer domains may be durably removed; UNKNOWN/ACTIVE remain unresolved; completion stays fail-closed.

E. Host-bound qualification

Provider readiness must be keyed to host identity and environment, including hostId, OS/arch, HOME, PATH, Node/runtime major, provider executable/version, auth readiness, DevSpace build/source, adapter generation and model identity.

Acceptance criteria

1. A server update that adds a tool can reach the active ChatGPT controller without losing current Core mutation authority.
2. If caller identity must change, there is a supported audited continuation path rather than an actor-mismatch dead end.
3. The controller can prove whether its callable tool surface matches the live server catalog.
4. A governed mutation can survive one tool-manifest refresh and continue through Candidate formation, direct evidence and Core verification without restarting implementation solely because of projection drift.
5. Mixed writer-domain reconciliation narrows only proven-clear domains and never treats UNKNOWN as absence.
6. Direct evidence accepts the actual successful worker lifecycle.
7. Cross-host DevSpace endpoints cannot be mistaken for equivalent continuation surfaces.
8. End-to-end regression proves no blind replay and no provenance bypass.
9. Normal operation does not require opening a new chat merely to expose tools the already-connected server advertises.
10. A server-generation change requires at most one deterministic refresh/rebind step, not repeated manual retries.

Non-goals

• weakening exact-effect identity or Core provenance
• allowing bare Git commits to masquerade as governed Candidates
• treating OUTCOME_UNKNOWN as retry permission
• bypassing independent Candidate acceptance
• changing HerdR gateway semantics in P0: implement thin DevSpace -> HerdR external-agent runtime gateway #236

Relationship to #236

#236 should remain focused on DevSpace -> HerdR gateway behavior, durable HerdR execution identity, reconciliation, latest-main integration and acceptance.

This issue owns the recurring controller/projection/provenance deadlock that is slowing #236 and will also affect future governed work.

Priority: P0 reliability / workflow throughput.

Wave 1 + Wave 2 checkpoint is complete and merged.

Integrated via PR #248:

• bootstrap commit: 7e40f22420d04222325ec1600b76f5319527a471
• merge/main: f127c6aee669172c6349a22ef290a850e866e3bf
• exact six-file target tree: 77ecd7eeb012d29ee34238f28cccafa042c00c1f

Wave 1 closure:

• direct evidence accepts settled idle|stopped + completed;
• active turn, termination-pending, corrupt/blocked lifecycle stays fail-closed;
• mixed writer reconciliation durably removes only independently proven-CLEAR domains and preserves unresolved domains.

Wave 2 closure:

• controller-facing CURRENT / SERVER_AHEAD_OF_CLIENT / STALE_RECONNECT_REQUIRED / CALLER_REBIND_REQUIRED;
• hashed stable caller identity plus optional hashed conversation identity;
• explicit client callable projection vs live server catalog convergence;
• server-ahead projection supports one same-session tools/list_changed refresh;
• cross-session refresh is rejected;
• mixed missing+extra projection drift requires reconnect;
• caller drift is detected without implementing caller handoff.

Verification:

• core mutation session: 25/25 PASS
• deployment convergence: 20/20 PASS
• capability generation: 6/6 PASS
• focused public MCP cases: PASS
• typecheck/build/diff-check: PASS
• full server suite: 82/83, with sole P1 Convergence: resolve RECONNECT_REQUIRED session snapshot deadlock after server restart #159 ECONNRESET independently reproduced on unmodified b8f4c965 baseline
• independent repaired-patch review: REVIEW_PASS
• GitHub CI: SUCCESS
• Repository Intelligence: SUCCESS

Important provenance note: 7e40f224 was formed through an Owner-authorized bootstrap escape hatch because the old ChatGPT callable projection omitted server-advertised git_commit / direct-evidence tools. Core correctly did not retroactively classify that bootstrap commit as a normally recorded Candidate. The exception remains explicit; it was not laundered into formal Candidate provenance.

Scope boundary:

• Wave 3 caller continuation/rebind is NOT implemented here.
• The full live server-generation N→N+1 refresh/caller-continuity E2E witness remains a later P0: fix ChatGPT↔DevSpace caller continuity, live tool projection, and evidence-chain liveness #240 E2E gate (Wave 5), not a Wave 2 requirement.
• P0: fix ChatGPT↔DevSpace caller continuity, live tool projection, and evidence-chain liveness #240 remains OPEN.

Next implementation gate: Wave 3 caller continuation/rebind.

[James3014]

Wave 3 independent audit found three concrete defects before merge; repair is in progress on an isolated M5 worktree and the original dirty implementation remains untouched.

1. Upgrade migration false-green: the draft added core_mutation_session_rebinds inside historical migration v19. Existing production DBs that already recorded v19/v20 would never rerun it, so the rebind table would be missing after upgrade even though fresh-DB tests pass. Repair: restore v19 semantics; add v21 core-mutation-session-rebinds plus upgrade-from-v20 regression.

2. Historical transition replay bug: draft idempotency searched any historical (session, from, to) pair before current-actor/state checks. Sequence A->B->A->B could return the first A->B receipt without changing the current actor. Repair: idempotent replay is only the latest exact transition while current actor is already the requested new actor, binding/evidence match exactly; repeated pairs after intervening transitions create a new ledger row. Pair UNIQUE index removed.

3. Transport ledger replay bug: public rebind callback appended callerRebinds[] even when Core returned an existing idempotent receipt. Repair: snapshot application is deduplicated by durable rebindId; duplicate replay returns the existing snapshot unchanged.

Focused repaired tests already PASS:

• caller rebind: 8/8, including same-evidence replay, different-evidence conflict, A->B->A->B, terminal historical replay, v20->v21 migration.
• deployment convergence: 21/21, including transport rebind replay dedupe.

Exact repair base: f127c6aee669172c6349a22ef290a850e866e3bf.
Core repair session: cms_1fc6bf7a684b4c7ea5c5c33056853bac on isolated M5 worktree.

The next affected-suite command was started with durable attemptKey issue240-wave3-affected-suites-1, but the M5 MCP control surface then began returning an internal transport failure for both command_status and even read-only convergence/Core-status calls. No blind resend or cross-host substitution is being used. Wave 3 is NOT accepted/merged yet; resume from exact attempt reconciliation when the M5 surface is readable.

[James3014]

Wave 3 caller continuation/rebind is merged.

PR #252 merged as:

• exact PR head: a390c1db8cb22d77450b261ecae682cb41ea84c8
• merge/main: f28af5ef92e80a190d61f4318837a631fc9c2fb5

Independent audit found and repaired three defects before merge:

1. production upgrade false-green: rebind ledger moved to new migration v21 instead of mutating already-applied v19;
2. historical A→B replay no longer swallows a later A→B after an intervening transition;
3. MCP session caller-rebind projection is idempotent by durable rebindId.

Test-quality audit also added an exact request-gate oracle: only core_mutation_session_rebind + CALLER_REBIND_REQUIRED crosses the stale-session gate; server/manifest/cutover staleness remains fail-closed.

Exact head CI: 13/13 SUCCESS, including Ubuntu/macOS smoke, Local agent sessions, continuation suites, Diff check, snapshot and terminal.

Important evidence boundary: during the M5 control-plane outage this Candidate was rebuilt through GitHub immutable objects, so no valid DEVSPACE_DIRECT_EVIDENCE + CORE_GENERIC_VERIFICATION_RESPONSE v4 acceptance receipt exists. The Owner-authorized merge is explicit integration authority, not a fabricated formal v4 Candidate acceptance artifact.

Wave 3 status: COMPLETE.
Next gate: Wave 4 host-bound qualification.

Architecture reconciliation — 2026-09-25

Fresh cross-repo audit keeps #240 as the DevSpace physical continuity owner, but narrows what it must not become.

#240 owns physical facts/mechanics for:

• server/session/client tool projection convergence;
• caller identity continuity and audited rebind;
• host-bound provider qualification;
• evidence-lifecycle continuity.

It does not own Nexus-wide READY_TO_EXECUTE or blocker precedence. James3014/Nexus-new#807 remains the sole controller-facing end-to-end readiness/convergence owner and should consume #240 outputs as physical evidence.

New adjacent owners:

• P0: extract Nexus recovery ownership from DevSpace into a transport-independent manager adapter #262 — remove Nexus recovery lifecycle ownership from DevSpace; Dev MCP becomes adapter-only to the transport-independent manager.
• P0: collapse Dev MCP self-cutover into one reconciled advancement contract #263 — collapse self-cutover choreography into one reconciled advancement contract.

Wave 4 host-bound qualification should therefore emit scoped facts (host/build/runtime/caller/projection/provider identities), not a second overall readiness verdict.

AUTO_CHAIN=false.

Fresh live-runtime reconciliation — 2026-09-25

Direct readback from the currently connected Dev MCP confirms the historical generation-drift problem is still physically present now, not only in prior audit notes.

Live caller/server generation

serverInstanceId = f8365872-c970-4fcd-81a0-3ded0c88ca26
sourceCommit     = 89828be8705913cd251b3855c6bcaa7526fa5ce2
buildId          = devspace-1.0.7-89828be8
session state    = CURRENT
session converged= true
cutover mode     = normal

The current callable catalog still reflects that generation; for example it does not expose the later #240 caller-rebind surface merged after this baseline.

Current GitHub source

Fresh GitHub readback in the same audit:

devspace/main = 94cfeb3e6543190769854914fb40c32f9086672e

Therefore the live controller is still running the pre-Wave-2/3 baseline lineage while source has advanced materially.

Why CURRENT is still insufficient

The same live capability_convergence_status reports:

• session/server: CURRENT / converged=true;
• multi-role accepted/installed/running identity: all bound to 89828be8, therefore internally converged;
• control-plane convergence: converged=false;
• blocker: TOPOLOGY_MANIFEST_STALE;
• topology's canonical-production source is separately recorded as e03fa9ea....

So CURRENT currently proves only the scoped session/server/accepted-deployment relationship. It does not prove equivalence to fresh GitHub main or global control-plane freshness.

Required #240 consequence

Keep the existing scoped states, but Wave 4 / final E2E must explicitly prove and report separate clocks:

fresh_repository_source
accepted_deployment
installed_generation
running_generation
session_generation
client_projection
control_topology
caller_continuity

No single unqualified CURRENT should be surfaced to a controller as a global readiness claim.

This live observation also reinforces the boundary already reconciled above:

• P0: fix ChatGPT↔DevSpace caller continuity, live tool projection, and evidence-chain liveness #240 = DevSpace physical generation/caller/projection facts;
• Nexus-new#807 = end-to-end readiness and blocker precedence;
• P0: collapse Dev MCP self-cutover into one reconciled advancement contract #263 = self-cutover lifecycle simplification.

No deployment/restart is authorized by this comment.

AUTO_CHAIN=false.

Post-completion reconciliation — current client projection regression

• tree: a224ca6afb1b51030430206dfda022be4a06adfe
• M5 running build: devspace-1.0.7-1f1ec946
• M5 server instance observed: e3114a9d-d16a-4a32-9b81-ebb94bba10a3

Fresh contradiction to the prior closure claim

The live M5 server catalog physically exposes:

• git_commit
• git_push
• git_promote_candidate
• direct_candidate_execution_evidence

But the current ChatGPT callable projection for the same M5 connector does not expose git_commit, git_push, or direct_candidate_execution_evidence.

The same live convergence report currently has:

session/server = CURRENT / converged=true
client_projection = null

So server/session convergence is still capable of reporting CURRENT while the actual ChatGPT action projection required for governed continuation is incomplete.

A second callable namespace (dev) does expose git_commit, but it is a physically different DevSpace server/state:

• source/build observed there: 3d8f522b... / devspace-1.0.7-3d8f522b
• different server instance/caller identity
• it reports ws_1a29266dae as not loaded / zero matching workspace sessions

It therefore cannot lawfully substitute for the M5 Core-bound attempt.

Concrete blocked execution

This regression currently blocks James3014/devspace#280 after its exact G1 payload has already passed its required focused verifiers. The active Core-bound workspace is:

• workspace: ws_1a29266dae
• Core session: cms_73b3933c5d8345d9a1dd62fe594d3b52
• source HEAD: 1f1ec9465dbb8edd0c67c91faee5d406878322ac
• exact dirty paths: src/server.ts, src/host-capability-snapshot.ts, src/host-capability-snapshot.test.ts

Candidate formation cannot legally proceed without the same M5 caller gaining the live git_commit action. Bare shell commit, alternate DevSpace server, direct Core store mutation, or synthetic Candidate provenance would violate the existing contract.

Required same-contract repair

#240 owns this exact original seam: live server catalog vs ChatGPT callable tool projection / same-actor continuation.

The next gate is to make the current M5 client projection truthfully reflect the live server tool catalog (or provide the already-defined safe same-caller refresh/rebind mechanism) and prove it on an effect-bearing Core-bound continuation.

Do not weaken provenance or treat server-side CURRENT alone as client-projection convergence.

AUTO_CHAIN=false.
