Verification Report

Summary Decision

  • Status: pass for public-release sanitization and offline implementation.
  • Git handoff ready: yes.
  • Live deployment status: approval_required.
  • Live systems, credentials, schedules, and private ledgers touched: none.

The repository, generated zipapp, generic commit attribution, and all reachable Git objects pass the public-release audit. The operational claim proven here remains offline: a harness can call the module or zipapp, parse success and failure JSON, execute fixture-backed collection, persist and verify an isolated append-only ledger, reject unsafe or incomplete inputs, and recover derived state without a GUI or downloaded runtime dependency.

Public-Release Changes

  • Replaced tenant-specific workspace, channel, user, and message fixtures with synthetic examples.
  • Replaced private organization and contributor attribution with project-level attribution.
  • Removed local profile paths, automation locations, private run timestamps, and run metrics.
  • Made workspace and channel allowlists runtime configuration while retaining syntax and Slack response identity checks.
  • Changed the example token variable and schedule timezone to generic values.
  • Added a repeatable tracked-tree, reachable-history, unreachable-object, and zipapp content audit.
  • Prevented the zipapp builder from copying bytecode or cache directories that can embed host paths.
  • Replaced the unpublished root commit with sanitized content and generic attribution.

Tests and Gates

Test or gate Status Evidence Notes
Sanitization red phase pass Audit module was absent; zipapp cache regression failed before fixes Expected failures observed
Full unit/integration suite pass 43 tests Fake Slack transport and temporary ledgers; no network
Focused public-release/config suite pass 12 tests Synthetic config, negative patterns, source-only zipapp
Python syntax compilation pass Package, tests, and scripts compiled Bytecode isolated to temporary output
Import smoke pass Package modules and release auditor imported Python 3.14.6 verification runtime
Line length and trailing whitespace pass No Python line over 100 characters; no trailing whitespace Built-in checks
Git diff whitespace gate pass git diff --check returned clean No bypass
Tracked/untracked tree audit pass Zero sensitive-pattern findings Includes new non-ignored files
Reachable Git history audit pass Zero sensitive-pattern findings Includes commit/tag/blob content
Unreachable Git object audit pass No dangling or unreachable objects after cleanup Reflogs expired before prune
Commit attribution audit pass Generic name and .invalid address One sanitized root commit
Ruff lint/format not run Ruff unavailable No dependency downloaded
mypy/pyright not run Type checkers unavailable Strict mypy config remains for CI/dev
Source-only zipapp build pass 84,594 bytes; SHA-256 6b091dd7db59b1418f0716a5fb344e101486b5d66b1bb717a2c7f4516391accc No bytecode/cache entries
Zipapp content audit pass Zero sensitive-pattern findings Source entries scanned
Zipapp offline doctor pass Parseable JSON; no token/network check Actual artifact invoked directly
Zipapp empty-ledger verify pass Record count 0; canonical/derived status empty Actual artifact invoked directly
PEP 517 wheel/install not run Build dependencies unavailable Direct Git and zipapp paths verified
Docker image build not run Would require a base-image pull Dockerfile reviewed only
Live Slack doctor/backfill not run No token or live approval Deployment airlock
Scheduler installation not run Examples only Deployment airlock

Failure and Remediation Ledger

Failure Classification Root cause Remediation Rerun result
Tree audit module missing expected TDD red Release gate did not exist Added bounded scanner and regression tests Focused tests passed
License words and fixed Slack host flagged detector false positives Identifier pattern lacked a digit constraint; service host looked tenant-specific Tightened ID semantics and allowed fixed Slack service hosts Tree audit passed
Weekly schedule fixture selected incremental test/config mismatch Example timezone changed to UTC but fixture retained a different offset Aligned the fixture with the public UTC example Full suite passed
Test copied config into repository root test isolation Fixture helper received the repository path Moved fixture to a temporary directory and removed the generated file Status remained clean
Zipapp contained bytecode caches packaging/privacy Builder copied the package directory without exclusions Excluded cache directories and bytecode; added a regression test Zipapp test/audit passed
Initial history audit found removed details Git history/privacy Clean working tree sat on the original local root commit Replaced root commit, expired reflogs, pruned objects, reran history audit History audit passed

Security Assertions Verified

  • Tracked content and the zipapp contain no user-profile paths, personal email addresses, private-key markers, OAuth-token-shaped values, host identifiers, non-example tenant URLs, or non-example Slack identifiers under the defined audit rules.
  • Package, license, author, and committer attribution is generic.
  • Any syntactically valid Slack tenant may be configured, but collection proceeds only after exact workspace and channel identity verification.
  • Duplicate and malformed configured identities fail before network collection.
  • Slack write methods remain rejected before transport.
  • Credentials remain environment-only and redacted from errors and output.
  • Failed or incomplete collection creates no canonical/checkpoint mutation.
  • Canonical JSONL remains append-only, hash-chained, tamper-evident, and authoritative.
  • Derived state can be rebuilt without rewriting canonical bytes.
  • Scheduler-facing output remains one parseable JSON object with nonzero structured failures.

Bypass Check

  • --no-verify used: no.
  • Hooks disabled: no.
  • Tests weakened or skipped: no.
  • Scanner rules suppressed: no.
  • Secret findings ignored: no.

Remaining Risks and Required Approvals

  • The audit is pattern-based and is paired with manual semantic review; it cannot prove the absence of every possible sensitive concept.
  • search.messages is legacy and may be affected by user search filters. Weekly full reconciliation mitigates polling misses but does not change the upstream contract.
  • A live operator must validate scopes, token type, membership, workspace URL, channel identity, pagination shape, and rate-limit behavior.
  • Python 3.11 was not available on the verification host; declared compatibility is based on syntax and configuration review while execution evidence is from Python 3.14.6.
  • Ruff, a static type checker, wheel installation, Docker build, and live Slack checks were not run.
  • Publication/push, container publication, live token use, existing-ledger migration, and schedule installation remain explicit operator actions.
